Annular brooch with animal heads The miscellaneous forms of annular brooch are: the broad-framed brooch, the chunkier annular brooch with ribbed decoration, and the late Anglo-Saxon period annular brooches. The broad-framed was a smaller brooch with a wider frame than the typical annular brooch. The chunkier annular is uncommon. It has a thicker oval frame and cast decoration with diagonally marked edges.
There are three main styles of annular brooch: flat annular, quoit style and miscellaneous.
Annular solar eclipses occur when the Moon's apparent diameter is smaller than the Sun's. Almost all annular solar eclipses between 1880 and 2060 in Solar Saros 144 and almost all annular solar eclipses between 1940 and 2120 in Solar Saros 128 are micromoon annular solar eclipses.
Annular characteristics can be attained as tropical cyclones intensify; however, outside the processes that drive the transition from asymmetric systems to annular systems and the abnormal resistance to negative environmental factors found in storms with annular features, annular tropical cyclones behave similarly to asymmetric storms. Most research related to annular tropical cyclones is limited to satellite imagery and aircraft reconnaissance as the conditions thought to give rise to annular characteristics normally occur over water well removed from landmasses where surface observations are possible.
During circulation, the bottom hole pressure is equal to the hydrostatic pressure on the annular side plus the annular pressure loss (APL).

This is the volume contained between the inside diameter of the hole and the outside diameter of the pipe. Annular capacity is given by : : Annular capacity (bbl/ft) = (IDhole2 \- ODpipe2) / 1029.4 where : IDhole2 = Inside diameter of the casing or open hole in inches : ODpipe2 = Outside diameter of the pipe in inches Similarly : Annular volume (bbls) = Annular capacity (bbl/ft) × length (ft) and : Feet occupied by volume of mud in annulus = Volume of mud (bbls) / Annular Capacity (bbls/ft).Jerome Jacob Schubert, 1995, pp.2-1, 2.
Bottom hole pressure is equal to hydrostatic pressure on the annular side, plus annular pressure loss, plus choke (casing) pressure. For subsea, add choke line pressure loss.
Annular hurricanes have a single eyewall that is larger and circularly symmetric. Observations show that an eyewall replacement cycle can lead to the development of an annular hurricane. While some hurricanes develop into annular hurricanes without an eyewall replacement, it has been hypothesized that the dynamics leading to the formation of a secondary eyewall may be similar to those needed for development of an annular eye. Hurricane Daniel (2006) and Typhoon Winnie (1997) were examples where a storm had an eyewall replacement cycle and then turned into an annular hurricane.
Regulations typically require that an annular preventer be able to completely close a wellbore, but annular preventers are generally not as effective as ram preventers in maintaining a seal on an open hole. Annular BOPs are typically located at the top of a BOP stack, with one or two annular preventers positioned above a series of several ram preventers. An annular blowout preventer uses the principle of a wedge to shut in the wellbore. It has a donut-like rubber seal, known as an elastomeric packing unit, reinforced with steel ribs.
Rail Core Drill or Rail Annular Cutters with Tungsten Carbide Tip. Available in 30 mm or 55 mm cutting lengths depending on the manufacturer. The Rail Annular Cutters or Rail Core Drills are one of the types of Annular Cutters. These rail core drills are made from Tungsten Carbide Tip.
During circulating with a rotating head the bottom hole pressure is equal to the hydrostatic pressure on the annular side, plus the annular pressure loss, plus the rotating head backpressure.
The intensity of annular systems is typically greater than 83.5% of the maximum potential intensity, suggesting that the conditions in which storms gain annular characteristics are generally conducive for tropical cyclone persistence and intensification. Annular tropical cyclones also require low wind shear, and of the storms in the East Pacific and North Atlantic studied by Knaff and Kossin, all exhibited easterly winds and cold air in the upper troposphere. In addition to strong outflow, suggesting that the conditions that give rise to annular tropical cyclones are most optimal towards the equatorward side of a subtropical ridge and within the tropics. However, warmer sea surface temperatures (SSTs) are not required for annular tropical cyclones, with annular characteristics developing only within a narrow range of modest SSTs, ranging from .
Although tropical cyclones can achieve annular characteristics across a wide spectrum of intensities, annular storms are typically strong tropical cyclones, with average maximum sustained windspeeds of 108 kn (200 km, 124 mph). In addition, storms attaining annular characteristics are less prone to weakening as a result of negative environmental factors. Annular cyclones can maintain their respective peak intensities for extended periods of time unlike their asymmetric counterparts. Following peak intensity, such systems will tend to gradually taper off.
An annular engine is an unusual type of engine that has an annular (ring- shaped) cylinder.Murray, pp.15-16. Some of American pioneering engineer James P. Allaire's early compound engines were of the annular type, with a smaller, high-pressure cylinder placed in the centre of a larger, ring-shaped low- pressure cylinder.Murray, pp. 376-377.
See engine description for Buckeye State. Trunk engines were another type of annular engine. A third type of annular marine engine used the Siamese engine connecting mechanism—but instead of two separate cylinders, it had a single, annular-shaped cylinder wrapped around the vertical arm of the crosshead (see diagram under "Siamese" above).Murray, pp. 15-16.
BOPs come in two basic types, ram and annular. Both are often used together in drilling rig BOP stacks, typically with at least one annular BOP capping a stack of several ram BOPs.

Ulcerative sarcoidosis is a cutaneous condition affecting roughly 5% of people with sarcoidosis. Annular sarcoidosis is a cutaneous condition characterized by papular skin lesions arranged in annular patterns, usually with a red-brown hue.
While usually annular, they may also be penannular like a brooch.
The annular lift fan concept uses two parallel annular fans counter-rotating about the central fuselage.(see plan view) The two fans are incorporated in an annular duct, separated by a baffle, but coupled by the gears in the baffle to counter- rotate and eliminate torque. During VTOL, the outer fan is driven pneumatically or mechanically by the jet engines in the outer wing. As the annular fan area can be made large enough, low disc loading and high hovering efficiency can be achieved in hover.
Atomic resolution imaging of SrTiO3, using annular dark field (ADF) and annular bright field (ABF) detectors. Overlay: strontium (green), titanium (grey) and oxygen (red). In annular dark-field mode, images are formed by fore-scattered electrons incident on an annular detector, which lies outside of the path of the directly transmitted beam. By using a high-angle ADF detector, it is possible to form atomic resolution images where the contrast of an atomic column is directly related to the atomic number (Z-contrast image).
In discussing the spur gear differential, the use of the term annular gear is a convenient way to distinguish the sun gears of the two epicyclic gear trains. The second sun gear serves the same purpose as the annular gear of a simple planetary gear train, but clearly does not have the internal gear mate that is typical of an annular gear.
This design is similar to the double-annular combustor in that it has two combustion zones; this combustor "swirls" the flow, creating an ideal fuel–air mixture. This difference allows the combustor to generate much less NOx than other combustors. Tests on a CFM56-7B engine demonstrated an improvement of 46% over single-annular combustors and 22% over double-annular combustors.Mongia, Hukam (2003).
The flat annular is the most common annular brooch form in early Anglo-Saxon England. It is constructed with a flat, wide circular ring, generally 35mm to 65mm in diameter. The ring is usually cast in copper alloy with a pin generally made of iron. The flat annular is constructed with either a closed ring or an open ring with overlapping ends.
At this time, Nestor began showing annular characteristics. Nestor began to weaken slowly, as typical annular typhoons do, while it developed an eye measuring 65 kilometers across. On June 15, Nestor transitioned into an extratropical cyclone.
In human anatomy, the annular ligaments of the fingers, often referred to as A pulleys, are the annular part of the fibrous sheathes of the fingers. Four or five such annular pulleys, together with three cruciate pulleys, form a fibro- osseous tunnel on the palmar aspect of the hand through which passes the deep and superficial flexor tendons. The annular and cruciate ligaments serve to govern the flexor mechanism of the hand and wrist, providing critical constraints to the flexor tendons to prevent bowstringing upon contraction and excursion of extrinsic flexor musculo-tendinous units. The first annular pulley (A1 pulley), near the head of the metacarpal bone, lies in the flexor groove in the deep transverse metacarpal ligament.
The tip of the snout is pale. The annular grooves are whitish.
In thermal engineering, an annular fin is a specific type of fin used in heat transfer that varies, radially, in cross-sectional area. Adding an annular fin to an object increases the amount of surface area in contact with the surrounding fluid, which increases the convective heat transfer between the object and surrounding fluid. Because surface area increases as length from the object increases, an annular fin transfers more heat than a similar pin fin at any given length. Annular fins are often used to increase the heat exchange in liquid–gas heat exchanger systems.
The atoms that are part of the ring structure are called annular atoms.
A small French toleware annular lamp stands on the sideboard to the right.
The annular hurricane was first defined as a subset of tropical cyclones by John Knaff of Colorado State University and James Kossin of the University of Wisconsin–Madison in 2002 by use of infrared satellite imagery, which serves as the visual means of ascertaining annular characteristics within tropical cyclone. Knaff and Kossin defined an annular tropical cyclone as a tropical cyclone that maintains either an average or larger-than-average eye surrounded by deep convection containing the storm's inner core and a lack of convection occurring outside the central dense overcast for at least three hours. As a result, annular storms lack the rainbands characteristic of typical tropical cyclone. These features lend the storm an axisymmetric appearance common to annular tropical cyclones.
Annular Cutters in TCT and HSS The magnetic core drilling machine utilizes core drills or annular cutters. With a cutter wall thickness of approximately 5 mm only a small amount of material around the edge of a hole is removed by an annular cutter. Numerous teeth remain sharper longer than the single pointed tip of a spiral drill. Holes produced are smooth and burr-free - no reaming is required.
This eclipse is a hybrid eclipse, starting and ending as an annular solar eclipse.
Satellite image of Hurricane Isabel of 2003, displaying a large, circular, and symmetric eye, and symmetrical storm shape, which are characteristics of annular tropical cyclones. Isabel is also exhibiting a pinwheel eye, a rare feature found in some annular tropical cyclones. An annular tropical cyclone is a tropical cyclone that features a normal to large, symmetric eye surrounded by a thick and uniform ring of intense convection, often having a relative lack of discrete rainbands, and bearing a symmetric appearance in general. As a result, the appearance of an annular tropical cyclone can be referred to as akin to a tire or doughnut.
An annular solar eclipse occurred on June 21, 2020. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. This was an annular solar eclipse because the Moon’s apparent diameter was 0.6% smaller than the Sun’s.
The green or white embryo is either spirally (and without perisperm) or annular (rarely straight).
Instead of having just one combustion zone, the double-annular combustor has a second combustion zone that is used at high thrust levels. This design lowers the emissions of both nitrogen oxides (NOx) and carbon dioxide (CO2). The first CFM56 engine with the double-annular combustor entered service in 1995, and the combustor is used on CFM56-5B and CFM56-7B variants with the suffix "/2" on their nameplates."CFM'S Advanced Double Annular Combustor Technology".
An annular-type blowout preventer can close around the drill string, casing or a non-cylindrical object, such as the kelly. Drill pipe including the larger- diameter tool joints (threaded connectors) can be "stripped" (i.e., moved vertically while pressure is contained below) through an annular preventer by careful control of the hydraulic closing pressure. Annular blowout preventers are also effective at maintaining a seal around the drillpipe even as it rotates during drilling.
A hybrid (annular/total) solar eclipse occurred on October 30, 1845 during winter. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A hybrid solar eclipse shifts between a total and annular eclipse. At certain points on the surface of Earth it appears as a total eclipse, whereas at other points it appears as annular.
A hybrid (annular/total) solar eclipse occurred on February 11, 1804. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An hybrid solar eclipse shifts between a total and annular eclipse. At certain points on the surface of Earth it appears as a total eclipse, whereas at other points it appears as annular.
In this particular case the eclipse path starts out as annular. Further down the track it changes to total and then back to annular before the path ends. It was the 23rd eclipse of the 143rd Saros cycle, which began with a partial eclipse on March 7, 1617 and will conclude with a partial eclipse on April 23, 2897. This hybrid solar eclipse started annular solar eclipse and ended total solar eclipse.

It is a hybrid eclipse, with portions of its path near sunrise and sunset as annular.
However, this definition is only applicable while a storm maintains these characteristics—when and while a storm does not feature annular characteristics, the tropical cyclone is considered asymmetric. In addition to the primary defining characteristics, the diurnal pulsation of the cirrus cloud canopy associated with outflow is subdued once storms become annular. Some annular tropical cyclones may also display a "pinwheel eye", a feature in which conditions in the storm causes its eye to take the appearance of a spoked wheel. An algorithm for identification of annular tropical cyclones in real-time by objective criteria has been developed, and shows some power, but is not yet operational.
Annular pustular psoriasis is a rare variant of pustular psoriasis, having an annular, or circinate, lesion morphology that may appear at the onset of pustular psoriasis, with a tendency to spread and form enlarged rings.Freedberg, et al. (2003). Fitzpatrick's Dermatology in General Medicine. (6th ed.). McGraw-Hill. .
Swirl fuel nozzles of a CFM56 annular combustor Most variants of the CFM56 feature a single- annular combustor. An annular combustor is a continuous ring where fuel is injected into the airflow and ignited, raising the pressure and temperature of the flow. This contrasts with a can combustor, where each combustion chamber is separate, and a canannular combustor which is a hybrid of the two. Fuel injection is regulated by a Hydromechanical Unit (HMU), built by Honeywell.
The annular atmospheric condenser was easier to control with respect to cooling rates. The gas in the tall vertical cylinders was annular in form and allowed an inside and outside surface to be exposed to cooling air. The diagonal side pipes conveyed the warm gas to the upper ends of each annular cylinder. Butterfly valves or dampers were fitted to the top of each vertical air pipe, so that the amount of cooling could be regulated.
This is about 4 minutes longer than total solar eclipses could ever get. (The solar eclipse of January 4, 1992, was longer, at 11 minutes, 40.9 seconds, occurring in the middle of the Pacific Ocean.)Annular Solar Eclipse Occurs on January 15, 2010 Lasting 11 minutes and 7.8 seconds, and eclipse magnitude of only 0.91903, this was the longest and smallest annular solar eclipse of the 21st century. It was an annular solar eclipse on January 15, 2010.

The annular ligament (orbicular ligament) is a strong band of fibers that encircles the head of the radius, and retains it in contact with the radial notch of the ulna.Gray's Anatomy (1918), see infobox Per Terminologia Anatomica, the spelling is "anular", but the spelling "annular" is frequently encountered.
Non-flying replica of the biplane In 1910 Cedric Lee approached Richards to work on an annular biplane which he had acquired half- finished from J. G. A. Kitchen. Together they finished the aeroplane, fitting a Gnome Omega engine in the front. The machine is known variously as the Kitchen annular biplane and the Lee-Richards annular biplane. Flight tests in 1911 were disappointing and that Autumn the biplane was destroyed on the ground by high winds, when its hangar collapsed.
Annular dark-field imaging is a method of mapping samples in a scanning transmission electron microscope (STEM). These images are formed by collecting scattered electrons with an annular dark-field detector. Conventional TEM dark-field imaging uses an objective aperture in order to only collect scattered electrons that pass through. In contrast, STEM dark-field imaging does not use an aperture to differentiate the scattered electrons from the main beam, but uses an annular detector to collect only the scattered electrons.

This was an annular solar eclipse because occurred in January and January is near its perihelion (closest approach to the Sun).
The xylem of anthesis flower parts and pedicels consists exclusively of tracheary elements with helical bands, and rarely, with annular bands.
In contrast the annular solar eclipse of January 26, 2009 (Saros 131, ascending node) occurred 3.3 days after lunar apogee and 7.175% smaller apparent diameter to the sun. And the next solar eclipse of January 15, 2010 (Saros 141, ascending node) was also annular, 1.8 days before lunar apogee, with the Moon 8.097% smaller than the Sun.
An annular eclipse will cross Europe and Russia. Eight European capitals will observe annual eclipse: Monaco, San Marino, Ljubljana, Zagreb, Vienna, Bratislava, Budapest and Moscow. For Moscow it will be the first central eclipse since 1887. Other European large cities (non- capitals), in which the annular eclipse will seen, include Barcelona, Marseille, Genoa, Graz, Lviv, Nizhny Novgorod, Kirov.
The path width of the large annular solar eclipse of May 9, 1948 was about 200 meters and lasted only 0.3 seconds. A large annular eclipse covered over 99% of the Sun, creating a dramatic spectacle for observers in only an extremely narrow strip; however, it was fleeting, lasting just moments at the point of maximum eclipse.
Fruiting spurs are specialized twigs that generally branch off the sides of branches and are stubby and slow-growing, with many annular ring markings from seasons past. The age and rate of growth of a twig can be determined by counting the winter terminal bud scale scars, or annular ring marking, down the length of the twig.
A guitarist usually performs Golpe with the middle or annular (ring) finger, either simultaneously with a down-stroke by another finger (e.g., simultaneous down-stroke with index finger and golpe with annular finger), or independently to accent off beats. The technique requires that the strumming finger and golpe finger move in opposite directions at the same time.
An ordinary Steiner chain is obtained by inverting an annular chain of tangent circles bounded by two concentric circles. This may be generalized to inverting three or more concentric circles that sandwich annular chains of tangent circles. Hierarchical Steiner chains are yet another generalization. If the two given circles of an ordinary Steiner chain are nested, i.e.
The vertical seed is disc- shaped with tuberculate to papillose surface. It contains a semi-annular embryo and copious perisperm (feeding tissue).
An annular solar eclipse occurred on January 15, 2010 with a magnitude of 0.9190. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. It was the longest annular solar eclipse of the millennium,NASA – Solar Eclipse Search Engine and the longest until December 23, 3043, with the length of maximum eclipse of 11 minutes, 7.8 seconds, and the longest duration of 11 minutes, 10.7 seconds.
In Andree's operation the annular cartilages were not divided, but only two punctures made in the membrane between them. No tube was introduced.
The stability of these annular polar vortices are still being researched as scientists believe Martian dust may play a role in their formation.
The palmar annular ligament is located on the back of the fetlock, covering the SDFT and DDFT as they wrap around the joint. Injury to the flexor tendons leads to inflammation, edema, and secondary compression of the surrounding tissues, similar to carpal tunnel syndrome. This makes it more difficult for the SDFT to glide over the surface of the joint, and the palmar annular ligament may thicken and adhere to the tendon sheath or SDFT, further reducing function of the SDFT and worsening lameness. Transection of the palmar annular ligament aims to release the pressure placed on these soft-tissue structures.
An annular solar eclipse took place at the Moon’s descending node of the orbit on May 9–10 (UTC), 2013, with a magnitude of 0.9544. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun fogghhvfhvsjvhr a viewer on Earth. An annular solar eclipse occurs whenshit the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide.
Initially filled with a cottony pith, the stem becomes hollow in maturity. A delicate ring forms an annular zone on the mid to upper portion of the stem that may be darkened from spore deposits. Above the annular zone, the stem is covered with fine silk-like hairs; below, it is sticky. The stem tissue is white with a yellowish pith.
Hybrid eclipses are comparatively rare. This eclipse is a hybrid event, a narrow total eclipse, and beginning and ending as an annular eclipse. The greatest eclipse was in the Sahara Desert in modern-day Algeria at 26.7 N, 4.5 W at 11:16:33 UTC, in that portion it shown as a total eclipse, the remainder was as an annular.
The fruit wall (pericarp) is membranous. The erect seed is oblong and red-brown, containing the half-annular embryo and copious perisperm (feeding tissue).
There are approximately 5000 formulas that are used today in the drilling industry. These formulas are mainly to do with annular dynamics and fluid dynamics.
The shell of this species is oblate, with red outer lip and light brown periostracum. Some individuals have 1~2 black or brown annular bands.
The Sun will be 94% covered in a moderate annular eclipse, lasting 7 minutes exactly and covering a broad path up to 238 km wide.
It is occupied by the base of the stapes, the circumference of which is fixed by the annular ligament to the margin of the foramen.
The Notch of Rivinus is a small defect in the posterior edge of the bony annular tympanic ring. The defect is located just superior to the tympano- mastoid suture line in the posterior ear canal. Following identification of the spine of Henle it is possible to follow the tympano-mastoid suture line medially towards the annular ring. At this location the Chorda Tympani Nerve is often identified.
Annular brooch The annular brooch style dates from the fifth to the seventh centuries in Anglo-Saxon England. It was common throughout southern England, the Midlands, East Anglia and North East England. It consists of a closed ring of wire or flattened metal with a pin set across it. The brooch style is plain, decorated simply with parallel marks or a circle of stamps.
Gap junctions were so named because of the "gap" shown to be present at these special junctions between two cells. With the increased resolution of the transmission electron microscope (TEM) gap junction structures were first able to be seen and described in around 1953. Annular gap junction cross section in TEM thin section. Gap junctions are usually linear rather than annular in TEM thin sections.
Changyi Li and his research team at the University of New Mexico recently showed that by changing the geometry of the openings on gallium nitride nanotubes, the shape of emitted light changes when acting as light-emitting diodes. The group used electron beam lithography to create well-defined annular shaped hollow regions within the gallium nitride nanotubes, which ultimately led to annular shaped emitted light.
The duration of annularity at maximum eclipse (closest to but slightly shorter than the longest duration) was 12 minutes, 9.17 seconds in the Indian Ocean. It was the longest annular solar eclipse from December 17, 168 to January 14, 3080. Among all the 23740 solar eclipses from 4000 BC to 6000 AD, 7881 are annular, and only 3 of them are longer than this one.
Some designs with a pull-down apex have the fabric removed from the apex to open a hole through which air can exit (most, if not all, round canopies have at least a small hole to allow easier tie-down for packing - these aren't considered annular), giving the canopy an annular geometry. This hole can be very pronounced in some designs, taking up more 'space' than the parachute. They also have decreased horizontal drag due to their flatter shape and, when combined with rear-facing vents, can have considerable forward speed. Truly annular designs - with a hole large enough that the canopy can be classified as ring-shaped - are uncommon.
In 1944, the German designer Ernst Heinkel began working on an annular-wing VTOL multirole single-seater called the Lerche, but the project was soon abandoned.

A small annular eclipse covered only 94% of the Sun in a very broad path, 499 km wide at maximum, and lasted 6 minutes and 35 seconds.
Pinion and annular gearA pinion is a round gear—usually the smaller of two meshed gears—used in several applications, including drivetrain and rack and pinion systems.
The fruit wall (pericarp) is membranous. The seed is lenticular to edge-shaped with tuberculate surface. It contains a semi-annular embryo and copious perisperm (feeding tissue).
Combustion chamber GE J79 Flame fronts generally travel at just Mach 0.05, whereas airflows through jet engines are considerably faster than this. Combustors typically employ structures to give a sheltered combustion zone called a flame holder. Combustor configurations include can, annular, and can- annular. Great care must be taken to keep the flame burning in a moderately fast moving airstream, at all throttle conditions, as efficiently as possible.
In 2014, Nerilie Abram used a network of temperature-sensitive ice core and tree growth records to reconstruct a 1000-year history of the Southern Annular Mode. This work suggests that the Southern Annular Mode is currently in its most extreme positive phase over at least the last 1000 years, and that recent positive trends in the SAM are attributed to increasing greenhouse gas levels and later stratospheric ozone depletion.
The machine is known variously as the Kitchen annular biplane and the Lee-Richards annular biplane. Flight tests in 1911 were disappointing and that Autumn the biplane was destroyed on the ground by high winds, when its hangar collapsed.Lewis (1962), pages 340-343. A non-flying replica later appeared in the 1965 film Those magnificent men in their flying machines and is now on display at the Newark Air Museum.
Tilghman Richards continued to promote the benefits of the annular wing, but without success. While working for Beardmore in 1916 he patented an improved method of construction. He went on to work for the Science Museum, London, where a model of a Lee-Richards annular monoplane is on display. During World War I Lee ended up with the Royal Naval Volunteer Reserve (RNVR) and was subsequently killed in action.
Positive and negative phases of the Arctic Oscillation The Arctic oscillation (AO) or Northern Annular Mode/Northern Hemisphere Annular Mode (NAM) is a weather phenomenon at the Arctic poles north of 20 degrees latitude. It is an important mode of climate variability for the Northern Hemisphere. The southern hemisphere analogue is called the Antarctic oscillation or Southern Annular Mode (SAM). The index varies over time with no particular periodicity, and is characterized by non-seasonal sea-level pressure anomalies of one sign in the Arctic, balanced by anomalies of opposite sign centered at about 37–45° N.Arctic Oscillation (AO) time series, 1899 – June 2002 The North Atlantic oscillation (NAO) is a close relative of the Arctic oscillation.
Consequently, the contrast mechanisms are different between conventional dark field imaging and STEM dark field. perovskite oxide strontium titanate (SrTiO3) taken with a high-angle annular dark field (HAADF) detector An annular dark field detector collects electrons from an annulus around the beam, sampling far more scattered electrons than can pass through an objective aperture. This gives an advantage in terms of signal collection efficiency and allows the main beam to pass to an electron energy loss spectroscopy (EELS) detector, allowing both types of measurement to be performed simultaneously. Annular dark field imaging is also commonly performed in parallel with energy-dispersive X-ray spectroscopy acquisition and can be also done in parallel to bright-field (STEM) imaging.
A hollow cylindrical bit which will cut a hole with an annular cross-section and leave the inner cylinder of material (the "core") intact, often removing it, is also called a core drill bit or annular cutter. Unlike other drills, the purpose is often to retrieve the core rather than simply to make a hole. A diamond core drill bit is intended to cut an annular hole in the workpiece. Large bits of similar shape are used for geological work, where a deep hole is drilled in sediment or ice and the drill bit, which now contains an intact core of the material drilled with a diameter of several centimeters, is retrieved to allow study of the strata.
An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. The annular eclipse was the first visible from the contiguous United States since the solar eclipse of May 10, 1994 (Saros 128), and the first in Asia since the solar eclipse of January 15, 2010 (Saros 141). The path of the eclipse's antumbra included heavily populated regions of China and Japan, and an estimated 100 million people in those areas were capable of viewing annularity.
Since all resins shrink (epoxy resins shrink far less than poly and vinyl ester versions) and it is impossible to bond to a sewer that has fats, oils, and grease an annular space exists between the new CIPP liner and the host pipe. The annular space exists in all installations just some are larger than others and depending on the severity may need additional rehabilitation. There are multiple ways to prevent water from tracking in the annular space and entering back into the waste stream including: water swelling material (hydrophilic), lining of the entire connection and host pipe with a continuous repair (YT repair) gaskets, and point repairs placed at the ends of the host pipe.
An annular solar eclipse occurred at the Moon's ascending node of the orbit on February 7, 2008. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring 7 days after apogee (January 31, 2008) and 6.9 days before perigee (February 14, 2008), the Moon’s apparent diameter was near the average diameter.
The fossils are well preserved due to extensive petrifaction. The trees' annular rings and pit structures are clearly visible, allowing their age to be determined by counting the rings.
The seed is ovoid to circular, compressed, with leathery, smooth or papillose seed coat. The seed contains the half-annular, uncinate or curved embryo and copious perisperm (feeding tissue).
Annular velocity is the speed of a fluid's movement in a column called an annulus in wells being drilled with circulating drilling fluid.Annulus (mathematics) It is commonly measured in feet per minute (ft/min) or meters per minute (m/min). Annular velocity is often abbreviated as AV, though this is not exclusively so, as AV also refers to apparent viscosity which is calculated from rheometer readings from tests that the mud engineer performs.
Atomic resolution imaging of SrTiO3, using annular dark field (ADF) and annular bright field (ABF) detectors. Overlay: strontium (green), titanium (grey) and oxygen (red). In scanning TEM (STEM), a focused probe is rastered over an area of interest, and a signal is recorded at each probe position to form an image. This typically requires different types of detector from conventional TEM imaging, in which a broad area of the specimen is illuminated.
The relatively thick outer layer is composed of annular muscles, and the similarly voluminous inner layer of longitudinal muscles. Between them lie thin diagonal muscles that wind backward and forward along the body axis in a spiral. Between the annular and diagonal muscles exist fine blood vessels, which lie below the superficially recognisable transverse rings of the skin and are responsible for the pseudo-segmented markings. Beneath the internal muscle layer lies the body cavity.
This brooch is composed of an incomplete circle of wire or flattened metal with a pin lying across it. It is less common than the annular brooch. Similar in decoration to the annular, the penannular is usually garnished with parallel marks or a ring of stamps. There are two main categories of the pennanular brooch found in Early Anglo-Saxon graves: one form with coiled terminals and another form with multifaceted terminals.
Annular sun eclipse on February 12, 1831 Beginning in February 1831, Turner claimed certain atmospheric conditions as a sign to begin preparations for a rebellion against slaveowners. On February 12, 1831, an annular solar eclipse was visible in Virginia. (This was coincidentally Abraham Lincoln's 22nd birthday.) He believed the eclipse to be a sign that it was time to revolt. Turner envisioned this as a black man's hand reaching over the sun.
The packing unit is situated in the BOP housing between the head and hydraulic piston. When the piston is actuated, its upward thrust forces the packing unit to constrict, like a sphincter, sealing the annulus or openhole. Annular preventers have only two moving parts, piston and packing unit, making them simple and easy to maintain relative to ram preventers. The original type of annular blowout preventer uses a “wedge-faced” (conical-faced) piston.
This indicates that growth had slowed substantially by the end of the third year. Each LAG is surrounded by two bands of dense avascular (i.e. lacking openings for blood vessels) bone, which Shen and colleagues termed the "pre-annular" and "post-annular" bands. The first LAG differs from the others in that it consists of two LAGs, one weaker than the other, indicating that growth mildly slowed before the resumption of bone growth.
Richards would continue to promote the benefits of the annular wing throughout his life, but without success. While working for Beardmore in 1916 he patented an improved method of construction.
The diameter of the annular distant field intensity distribution (b) is proportional to the length l. The width of the ring is about half the diameter of the incident beam.
Annular elastolytic giant-cell granuloma (also known as "Giant cell elastophagocytosis," "Meischer's granuloma," "Miescher's granuloma of the face") is a cutaneous condition characterized histologically by a dermal infiltrate of macrophages.

Well "integrity was not considered a risk" due to the "integrity of the casing, and the cement, in the upper completion", "confirmed by surface gas measurements and annular pressure readings".
Along with the advantages of dendroclimatology are some limitations: confounding factors, geographic coverage, annular resolution, and collection difficulties. The field has developed various methods to partially adjust for these challenges.
The last annular eclipse in Britain was on April 8, 1921, and if you miss out this time, there will not be another visible one in Scotland for 90 years.
At the same time, the shadow (antumbra) of Phobos moves across the Martian surface. The event could also be regarded as a particularly quick and shallow annular solar eclipse by Phobos.
The horizontal seed is orbicular or reniform, with dark brown, smooth or glossy seed coat. The seed contains an annular embryo and copious perisperm. The base chromosome number is x = 9.
Motion constraints on lipids in lipid bilayers are also imposed by presence of proteins in biological membranes, especially so in the annular lipid shell 'attached' to surface of integral membrane proteins.
The embryo is curved, half-annular or horseshoe-shaped, rarely only slightly curved. In most genera, the seed contains copious perisperm, but a feeding tissue is missing in Salicornia and Sarcocornia.
Lateral bottom view with the annular duct closed off by shutter or louvers After the aircraft reaches the speed of aerodynamic flight, the annular duct is closed off by shutters mounted at the top and bottom of the duct to form a smooth disc wing. The lift fans stop working and are enclosed in the annular duct during cruise flight. The traditional ailerons and elevators located at the rear edge of the outer wing are needed for roll and pitch control, but the rudder probably is not necessary. According to the CFD simulations, turbofans with a thrust-to-weight ratio of 0.3 can enable a top forward speed of Mach 0.62 (759 km/h) based on aerodynamic drag predictions, much faster than helicopters and tiltrotors.
A top view and side view sketch of the motion of an Annular Fluidized Beds The annular fluidized bed is a new type of fluidized bed that has a specific type of motion where it moves in radial. There is relatively little axial mixing of gases and there is radial motion. The axial flow profile of the annular fluidized bed can be determined by pressure drops along the plant height, which can be divided into three major parts: the annulus, the bottom and the top part of the mixing chamber. Based on the height of the bed, while the annulus has a porosity close to the solids minimal fluidization porosity, each region of bed is characterized by different pressure gradients.
The single cone supersonic intake supplied ram air to a long annular diffuser terminating at the aft-mounted cylindrical combustion chamber. The centreline of the intake system was gently curved, presumably to line up the intake face with the flow-field of the missile nose section. The combustion chamber flame-holder consisted of a center-body pilot region, with three annular V-gutters interconnected by slanted radial V-gutters. Fuel jets were of variable area design.
Historic saros cycle animation January 3, 1927 event from Buenos Aires, Argentina Partiality from annular event Series member 24 February 26, 2017 event from Buenos Aires, Argentina Partiality from annular event Series member 29 Saros cycle series 140 for solar eclipses occurs at the Moon's descending node, repeating every 18 years, 11 days, containing 71 events. All eclipses in this series occurs at the Moon’s descending node. This solar saros is linked to Lunar Saros 133.
An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Occurring only 4.8 days after apogee (September 28, 2005), the Moon's apparent diameter was smaller. It was visible from a narrow corridor through the Iberian peninsula and Africa.
Patent Drawing of Original Shaffer Spherical-type Blowout Preventer (1972) Diagram of an Annular blowout preventer in open and fully closed configurations. The flexible annulus (donut) in blue is forced into the drillpipe cavity by the hydraulic pistons. The annular blowout preventer was invented by Granville Sloan Knox in 1946; a U.S. patent for it was awarded in 1952. Often around the rig it is called the "Hydril", after the name of one of the manufacturers of such devices.
An annular solar eclipse has a magnitude of less than 1.0 The magnitude of eclipse is the fraction of the angular diameter of a celestial body being eclipsed. This applies to all celestial eclipses. The magnitude of a partial or annular solar eclipse is always between 0.0 and 1.0, while the magnitude of a total solar eclipse is always greater than or equal to 1.0. The cycle of magnitude of eclipse is 141 years minus 1 month.
Therefore, fuel injectors located in the burners were given two stages, resulting in good efficiency over a large operational range. ;Combustion chamber The chamber was a can- annular design. Based on experiences with Junkers' can-type chambers (Jumo 004) and BMW's annular-type chambers (BMW 003), this design choice was successfully applied already during the Soviet period. 12 burner cans and 60 air pockets (integrated into inner and outer wall) were used, along with several more air canals.

The eyes are visible through a layer of skin. Living animals have blue-black coloration. The annular grooves are ventrally marked with dark pigment, in sharp contrast to the otherwise pale venter.
The eclipse magnitude varies not only between eclipses, but also by viewing location. An eclipse may be annular in one location and total in another. These mixed-type eclipses are called hybrid.
Note: The partial solar eclipse of April 8, 1902, the annular solar eclipse of March 29, 1903 and the total solar eclipse of September 21, 1903 occur during the next lunar year set.
The tepals can enlarge or develop wings, spines or long hairs, or become fleshy or woody. The seed with thin testa contains an annular or folded embryo sometimes engirdling a rudimentary central perisperm.
A lockbolt is a fastener similar to a bolt in appearance and function. However, instead of using screw threads which connect to a nut using a turning motion, a lockbolt has annular grooves around the shaft of the bolt (pin). After placing the lockbolt in a hole, a threadless collar is forced at high pressures around the annular grooves, deforming the collar and permanently locking it into place around the grooves. Swaging is the generic term for setting a lockbolt and collar assembly.
Annular eclipse of the Sun by Phobos (Curiosity, August 20, 2013) Eclipse of the Sun by Phobos, the larger of the two moons of Mars, in real time (Curiosity, August 20, 2013) The two moons of Mars, Phobos and Deimos, are much smaller than the Moon, greatly reducing the frequency of solar eclipses on that planet. Neither moon's apparent diameter is large enough to cover the disk of the sun, and therefore they are annular solar eclipses and can also be considered transits.
This unusual intensity persistence makes their future intensities difficult to forecast and often results in large forecast errors. In an analysis of hurricanes in the East Pacific and North Atlantic between 1995 and 1999, Knaff and Kossin observed that the National Hurricane Center underestimated the intensity of annular hurricanes 72 hours out by 18.9 kn (35.0 km/h, 21.7 mph). A survey of Pacific typhoons between 1990 and 2009 found only 12 with annular characteristics, representing an occurrence rate of 4 percent.
The head is cylindrical to allow axial rotation of the radius, thus to articulate with the annular ligament and the radial notch on the ulna. However, the head of the radius is not perfectly cylindrical but slightly oval. In anatomical position, its major axis () is directed antero-posteriorly and the shorter axis () lateralo- medially. Even though the annular ligament holds the head firmly in place, the ligament is still flexible enough to allow some stretching while the head rotates within it.
A total solar eclipse will occur on December 6, 2067. It is a hybrid event, beginning and ending as an annular eclipse. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring).
The cities of San Antonio and Corpus Christi, Texas will also be in the direct path of this annular eclipse. Occurring only 4.6 days after apogee (Apogee on October 10, 2023), the moon's apparent diameter will be smaller. Future total solar eclipses will cross the United States in April 2024 (12 states) (Saros 139, Ascending Node) and August 2045 (10 states) (Saros 136, Descending Node), and an annular solar eclipse will occur in June 2048 (9 states) (Saros 128, Descending Node).
Section drawing of an annular fluidized bed Fluidisation is a phenomenon whereby solid particulate is placed under certain conditions to cause it to behave like a fluid. A fluidized bed is a system conceived to facilitate the fluidisation. Fluidized beds have a wide range of applications including but not limited to: assisting with chemical reactions, heat transfer, mixing and drying. A recent concept devised and patented by Outotec, "An annular fluidized bed consists of a large central nozzle surrounded be a stationary fluidized" .
Scand Cardiovasc J. 2003 Sep;37(5):253-8 It shares the advantage of annular displacement, that it is reduced also in hypertrophic hearts with small ventricles and normal ejection fraction (HFNEF), which is often seen in Hypertensive heart disease, Hypertrophic cardiomyopathy and Aortic stenosis.Yip G, Wang M, Zhang Y, Fung JW, Ho PY, Sanderson JE.

By 1938, radical modifications from the first prototype began to produce a "heavy" dive bomber. The wings were strengthened, dive brakes were added, the fuselage was extended and the number of crewmen was increased to four. Due to these advances, the Ju 88 was to enter the war as a medium bomber. Annular radiator on a wrecked Ju 88 The choice of annular radiators for engine cooling on the Ju 88, which placed these radiators immediately forward of each engine and directly behind each propeller, allowed the cooling lines for the engine coolant and oil-cooling radiators (integrated within the annular design) to be as short as possible, with integral port and starboard air intakes for cooling the exhaust headers, the starboard inlet also supplying the inlet air for the supercharger.
This event is a hybrid, starting and ending as an annular eclipse. Annularity was visible from Chile, Argentina, Uruguay and southern Brazil, while totality was visible only from southern Atlantic Ocean with no land.
These shared traits include: tracheids with scalariform pits with tori interspersed with annular thickenings, absence of scalariform pitting in primary xylem, scale-like and strap-shaped leaves of Ephedra and Welwitschia; and reduced sporophylls.
On the ulnar side, the capsule reaches down to the posterior part of the annular ligament. The posterior capsule is attached to the triceps tendon which prevents the capsule from being pinched during extension.
CFM International Press Release. 9 July 1998. Retrieved 16 November 2009. GE started developing and testing a new type of combustor called the Twin Annular Premixing Swirler combustor, or "TAPS", during the Tech 56 program.
The center of the Moon's shadow missed the Earth's South Pole, but the partial eclipse was visible from parts of Antarctica and Australia, and an annular eclipse was visible from a small part of Antarctica.
An architectural marvel, the dome has a framework of brick supported by an annular arch and is filled in by pottery cones. Its blue interior is formed by crushed sea shells mixed with lapis lazuli.
As described the schizonts were annular and amoeboid and between 1/5 and 1/6 of the erythrocyte in size. Black pigment was seen. 9-11 merozoites per schizont were seen. The gametocytes were oval.
Annular pancreas is characterized by a pancreas that encircles the duodenum. It results from an embryological malformation in which the early pancreatic buds undergo inappropriate rotation and fusion, which can lead to small bowel obstruction.
LET is usually found on sun-exposed areas of the body. Skin lesions are edematous, urticarialike annular papules and plaques. Topical corticosteroids are not effective as treatment for LET, but many will respond to chloroquine.
Sometimes systemic drug treatment is necessary. Besides corticosteroids other immunosuppressants such as methotrexate are also used. Lesions of SCLE may have an annular (shaped like a ring) configuration, with raised red borders and central clearing.
The annular velocity is one of two major variables in the process of cleaning solids (drill cuttings) from the wellbore. By maintaining the annular velocity at certain rates (speeds) in conjunction with the rheological properties of the drilling fluid, the wellbore is kept clean of the drill cuttings to prevent them from settling back down to the bottom and causing drilling problems. The other major variable is the rheology of the drilling fluid. Rheology is sometimes thought of as viscosity to the uninitiated, though improperly.
Figure 2: An annular hexlet. The annular Soddy's hexlet is a special case (Figure 2), in which the three mutually tangent spheres consist of a single sphere of radius r (blue) sandwiched between two parallel planes (green) separated by a perpendicular distance 2r. In this case, Soddy's hexlet consists of six spheres of radius r packed like ball bearings around the central sphere and likewise sandwiched. The hexlet spheres are also tangent to a fourth sphere (red), which is not tangent to the other three.
Conditions favorable for annular typhoon development in the Western North Pacific are localized within two areas within a zonal belt between 20°N−30°N; one of these areas lies over the central part of the basin, while the other is located east of Taiwan. Within the Eastern North Pacific, such conditions were present only 3 percent of the time between 1998 and 1999. In the same timeframe, the North Atlantic basin only exhibited conducive conditions for annular development 0.8 percent of the time.
Although the basic configuration of both engines was almost identical, the -07 variant had a larger fan diameter. The -06 version HP compressor was based on the eight- stage version of the RC34B research compressor, unscaled, whereas the -07 was a scaled-up unit. A single stage fan, driven by a two-stage LP turbine, supercharged the HP compressor which was driven by the single stage transonic HP turbine. The combustor was annular and the co-annular exhaust featured a lightweight target type thrust reverser.
An annual solar eclipse occurred on November 12, 1947. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring). An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide.
Gas-flow diagram of Olympus Mk 101 The first engine, its development designation being BOl.1 (Bristol Olympus 1), had six LP compressor stages and eight HP stages, each driven by a single-stage turbine. The combustion system was novel in that ten connected flame tubes were housed within a cannular system: a hybrid of separate flame cans and a true annular system. Separate combustion cans would have exceeded the diameter beyond the design limit, and a true annular system was considered too advanced.Baxter 1990, p.
Levitt, 2013, p. 59.) Nor was Fresnel the first to suggest replacing a convex lens with a series of concentric annular prisms, to reduce weight and absorption. In 1748, Count Buffon proposed grinding such prisms as steps in a single piece of glass. In 1790 (although secondary sources give the date as 1773 or 1788), the Marquis de Condorcet suggested that it would be easier to make the annular sections separately and assemble them on a frame; but even that was impractical at the time.
Blow extrusion of plastic film The manufacture of plastic film for products such as shopping bags and continuous sheeting is achieved using a blown film line. This process is the same as a regular extrusion process up until the die. There are three main types of dies used in this process: annular (or crosshead), spider, and spiral. Annular dies are the simplest, and rely on the polymer melt channeling around the entire cross section of the die before exiting the die; this can result in uneven flow.
Information regarding the W33 has suggested that it was either a double gun and/or that it may have used an annular barrel assembly. The device's internal mechanism was apparently code- named Fleegle. A double gun mechanism reduces the required velocity of each projectile by half, which reduces the gun system weight by a factor of 8. An annular bore may allow a larger projectile which remains subcritical by itself (a hollow projectile has lower effective density, and critical mass scales with the square of density).
Hybrid eclipses are comparatively rare. This eclipse is a hybrid event, a narrow total eclipse, and beginning and ending as an annular eclipse. The greatest eclipse was in northeasternmost Antarctica south of where the Indian and Pacific Ocean divides at 69.1 S and 144.5 E at 23:51 UTC (9:51 am on October 31), in that portion of Antarctica and the surrounding waters it shown as a total eclipse, the remainder was as an annular, first in the Indian Ocean then in the Antarctic Peninsula.
The proximal radioulnar articulation (superior radioulnar joint) is a synovial pivot joint between the circumference of the head of the radius and the ring formed by the radial notch of the ulna and the annular ligament.
Adult males measure and adult females in total length. The eyes are not visible. The snout projects strongly beyond the recessed mouth. The body has 150 to 157 annular grooves and is subcylindrical, slightly dorsoventrally flattened.
Richea gunnii is a common montane shrub that grows in boggy areas. It is an erect shrub, 30–100 cm high. The branches are divaricate. Mature stems become bare of leaves and show prominent annular scars.
Typhoon Noru of 2017, displaying all annular characteristics (minus the pinwheel eye) Tropical cyclones can become annular as a result of eyewall mesovortices mixing the strong winds found in the eyewalls of storms with the weak winds of the eye, which helps to expand the eye. In addition, this process helps to make the equivalent potential temperature (often referred to as theta-e or \theta_e) within the eye relatively uniform. This transition takes roughly 24 hours to complete and can be considered a type of eyewall replacement cycle. Winds have also been found to decrease in a stairstep like fashion within the radius of maximum wind, which may indicate that more wind is mixed between the eye and eyewall as cyclones strengthen, which helps to explain why annular characteristics are generally exclusive to storms of higher intensities.
The following day, Longwang underwent a structural change, transitioning from asymmetrical banding to symmetrical, making it an annular tropical cyclone. During the transition, upper-level divergence and outflow significantly decreased, resulting in temporary weakening of the typhoon.
Solar Saros 136 repeats every 18 years, 11 days, 8 hours. Solar Saros 136 contains 71 events in which of 15 will be partial eclipses and 56 will be umbral eclipses (6 annular, 6 hybrid, 44 total).
In DRAM, the array and periphery are exposed at different illumination conditions. For example, the array could be exposed with dipole illumination while the periphery could use annular illumination.T. Winkler et al., Proc. SPIE 5754, 1169 (2005).

For solar eclipses the statistics for the complete saros series within the era between 2000 BC and AD 3000 are given in this article's references. It takes between 1226 and 1550 years for the members of a saros series to traverse the Earth's surface from north to south (or vice versa). These extremes allow from 69 to 87 eclipses in each series (most series have 71 or 72 eclipses). From 39 to 59 (mostly about 43) eclipses in a given series will be central (that is, total, annular, or hybrid annular-total).
A total solar eclipse will occur on November 25, 2049. It is a hybrid event, with only a fraction of its path as total, and longer sections at the start and end as an annular eclipse. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring).
A number of different terms are used to denote the CHF condition: departure from nucleate boiling (DNB), liquid film dryout (LFD), annular film dryout (AFD), dryout (DO), burnout (BO), boiling crisis (BC), boiling transition (BT), etc. DNB, LFD and AFD represent specific mechanisms which will be introduced later. DO means the disappearance of liquid on the heat transfer surface which properly describes the CHF condition; however, it is usually used to indicate the liquid film dryout from annular flow. BO, BC and BT are phenomenon-oriented names and are used as general terms.
Air Cooled Condensers Condensers were either air cooled or water cooled. Air cooled condensers were often made up from odd lengths of pipe and connections. The main varieties in common use were classified as follows: Horizontal Air Cooled Condenser (a) Horizontal types Vertical Air Cooled Condenser (b) Vertical types Annular Air Cooled Condenser (c) Annular types Battery Air Cooled Condenser (d) The battery condenser. The horizontal condenser was an extended foul main with the pipe in a zigzag pattern from end to end of one of the retort-house walls.
An annulus Illustration of Mamikon's visual calculus method showing that the areas of two annuli with the same chord length are the same regardless of inner and outer radii. In mathematics, an annulus (the Latin word for "little ring" is anulus / annulus, with plural anuli / annuli) is a ring-shaped object, a region bounded by two concentric circles; equivalently, it is the set difference between two concentric disks. The adjectival form is annular (as in annular eclipse). The open annulus is topologically equivalent to both the open cylinder and the punctured plane.
This eclipse is a hybrid event, a narrow total eclipse, and beginning and ending as an annular eclipse. It was visible within a narrow corridor in the Pacific Ocean. The path of the eclipse started south of New Zealand and crossed the Pacific Ocean in a diagonal path and ended in the extreme northwestern part of South America. The total solar eclipse was not visible on any land, while the annular solar eclipse was visible in the southern tip of Puntarenas Province of Costa Rica, Panama, Colombia and Venezuela.
As the piston rises, vertical movement of the packing unit is restricted by the head and the sloped face of the piston squeezes the packing unit inward, toward the center of the wellbore. In 1972, Ado N. Vujasinovic was awarded a patent for a variation on the annular preventer known as a spherical blowout preventer, so-named because of its spherical-faced head. As the piston rises the packing unit is thrust upward against the curved head, which constricts the packing unit inward. Both types of annular preventer are in common use.
Artifacts are found, typically redeposited, deflated, or both, in Late Pleistocene to early Holocene gravelly mud, muddy gravel, clayey sand, and silty sand. These sediments are often cemented into either concretionary masses or beds by calcrete. Ridges typically consist of deeply weathered bedrock representing truncated Cenozoic paleosols that formed under tropical environments. The Pleistocene to Middle Holocene sediments occur along wadis as thin, meter- to less than meter-thick accumulations in the interior annular depressions to thick accumulations along the wadis in the outermost annular depression of the Richat Structure.
Advancements in technology have allowed the development of transgenic mice expressing A53T alpha-synuclein that have been used in multiple studies on Parkinson's disease. Wild-type alpha-synuclein has been shown to form oligomeric species termed protofibrils before forming full fibrils. Research has been conducted to test the hypothesis that the oligomeric protofibril species is neurotoxic rather than the fibrillar species. Electron microscopy has revealed that the A53T mutant protein formed annular and tubular protofibrils easily, whereas the wild-type protein formed annular protofibrils only after extended incubation.
Bonded Seals are made by Trelleborg in the United Kingdom to the original specification. A bonded seal consists of an outer annular ring of a hard material, typically steel, and an inner annular ring of an elastomeric material that acts as a gasket. It is the compression of the elastomeric part between the faces of the parts on either side of the bonded seal that provides the sealing action. The elastomeric material, typically nitrile rubber, is bonded by heat and pressure to the outer ring, which holds it in place.
The stipe is pruinose (powdery) or smooth towards the upper region. The velum sometimes leaves a partial annular (ringed) zone. It bruises bluish to blackish when injured, sometimes with the entire stipe completely blue or with vinaceous tones.
Cutting with a hole saw is analogous to some machining operations, called trepanning in the trade, that swing a cutter analogous to a fly cutter in order to achieve a similar result of annular kerf and intact core.
The fruit wall (pericarp) is free. The horizontal seed is black, with a hard, thin, glossy seed coat. It contains an annular embryo and mealy perisperm (feeding tissue). The flowering and fruiting phase reaches from July to November.
The membranous pericarp adheres to the vertically orientated seed. The dark seed coat is spiny or smooth. The embryo is annular, surrounding the copious, farinaceous perisperm. The chromosome base number is x = 6, which is unusual for Chenopodioideae.
Similar equations can also be derived for the obscured Airy diffraction patternRivolta, Applied Optics, 25, 2404 (1986).Mahajan, J. Opt. Soc. Am. A, 3, 470 (1986). which is the diffraction pattern from an annular aperture or beam, i.e.

It requires ample water in summer and benefits from application of non-phosphate based organic fertilisers along with manure and mulch. This species also responds well to annular pruning, and its attractive evergreen foliage can be harvested for floriculture.
Generalized granuloma annulare is a skin condition of unknown cause, tending to affect women in the fifth and sixth decades, presenting as a diffuse but symmetrical, papular or annular eruption of more than ten skin lesions, and often hundreds.
Crux Easton wind engine is a Titt Simplex geared wind engine. It has a diameter sail mounted on a hexagonal steel tower. The annular sail has 48 blades, each one long. It is winded by a six blade fantail.
This test proved the nozzle control system unacceptable. The spoilers were intended to direct the air out over the top or bottom of the annular flap, out the bottom only during hover, but over the top and bottom during forward flight.
The tepal lobes are not modified and appressed to the fruit. The solitary fruits are nearly globular capsules, they fall down when ripe and open with a circumscissile lid. The vertical seed contains an annular embryo and copious perisperm (feeding tissue).
There are also a wide variety of Anglo-Saxon fibulae from the 5th to 7th century such as the equal-arm type and the small-long type. Most Viking fibulae are variations on the ring or annular design (see below).
The flexor retinaculum (transverse carpal ligament, or anterior annular ligament) is a fibrous band on the palmar side of the hand near the wrist. It arches over the carpal bones of the hands, covering them and forming the carpal tunnel.
Alternatives to nested wells are engineered nested wells or multilevel monitoring systems that are designed to provide robust annular seals along with the ability to collect groundwater samples and measure hydraulic heads at many discrete depths in a single well.
The zona orbicularis or annular ligament is a ligament on the neck of the femur formed by the circular fibers of the articular capsule of the hip joint. It is also known as the orbicular zone, ring ligament, and zonular band.
The Supermarine Spitfire uses a modified elliptical wing. An elliptical wing is a wing planform whose leading and trailing edges each approximate two segments of an ellipse. It is not to be confused with annular wings, which may be elliptically shaped.
The cloaked region is a cylindrical [annular] region between the first and last lenses. For a shorter 3 lens symmetric cloak the middle lens can be diverging to give a '3D triangular-ring' cloaked region between the first and last lenses.
Some have achieved successful transition between flight modes, as the turboprop-powered Convair XFY Pogo did in November 1954."Convair XFY." Flight, 12 November 1954, p. 696. The coleopter type has an annular wing forming a duct around a lift rotor.
Isaac Newton Vail, from his 1912 book The Earth's Annular System Isaac Newton Vail (1840-26 January 1912) was an American Quaker, schoolteacher, and pseudoscientist supporting the theory of catastrophism. His ideas were taken up by creationists including Jehovah's Witnesses.
The fruit in an ovoid, compressed utricle with membranous pericarp. The erect seed is brown or reddish brown, oblong, with smooth surface. It contains copious perisperm (feeding tissue), and a half-annular embryo. The chromosome basic number is x = 9.
The annular embryo surrounds the perisperm. The chromosome base number is x = 9, except for Atriplex lanfrancoi, which is x=10. A few Atriplex species are C3-plants, but most species are C4-plants, with a characteristic leaf anatomy (kranz anatomy).
The annular embryo surrounds the copious perisperm. The chromosome number is 2n = 36. The shrub sheds its leaves and flowers by the summer in hot or dry areas and becomes a woody gray thicket; it is evergreen in some regions.
An ameboma, also known as an amebic granuloma, is a rare complication of Entamoeba histolytica infection, where in response to the infecting amoeba there is formation of annular colonic granulation, which results in a large local lesion of the bowel.
An annular closed wing A closed wing is a wing that effectively has two main planes which merge at their ends so that there are no conventional wing tips. Closed wing designs include the annular wing (commonly known as the cylindrical or ring wing), the joined wing, the box wing and spiroid tip devices. Like many wingtip devices, the closed wing aims to reduce the wasteful effects associated with wingtip vortices which occur at the tips of conventional wings. Although the closed wing has no unique claim on such benefits, many closed wing designs do offer structural advantages over a conventional cantilever monoplane.
A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. The eclipse is either total or annular. In a total eclipse, the moon's size from earth is large enough to block all of the disk of the sun. An annular solar eclipse occurs when the Moon's apparent diameter is smaller than the Sun's, blocking most of the Sun's light and causing the Sun to look like an annulus (ring), that is there is a ring of the sun around the dark moon.
Schematic representation of solvent extraction and countercurrent stagewise process The industrial separation processes will be implemented stepwise by annular centrifugal contactors, developed for the first time at Argonne National Laboratory in the 1970s. The countercurrent process consists of the aqueous and organic phases moving continuously in opposite directions stage by stage. The two immiscible liquids enter each contactor unit, first contacted in the annular region between the housing and the spinning rotor and then centrifuged in the inner part of the unit. Two main ways are currently followed within the partitioning strategy: the heterogeneous and homogeneous recycling.
The claws of the feet are used only on hard, rough terrain where a firm grip is needed; on soft substrates, such as moss, the velvet worm walks on the foot cushions at the base of the claws. Actual locomotion is achieved less by the exertion of the leg muscles than by local changes of body length. This can be controlled using the annular and longitudinal muscles. If the annular muscles are contracted, the body cross- section is reduced, and the corresponding segment lengthens; this is the usual mode of operation of the hydrostatic skeleton as also employed by other worms.
The aircraft was to be propelled by this wing rotation. For takeoff and landing it would fly vertically as a helicopter, then tilt over horizontally to fly as a self-propelled wing generating both lift and thrust. The contemporary Heinkel Lerche project had an annular wing forming a duct around a conventional propeller, and in the transition from vertical to forward flight the lift would have transferred to the wing. Dan Sharp, Luftwaffe: Secret Weapons of the Third Reich, Mortons, 2015 The SNECMA Coléoptère was a postwar French development of the annular wing concept, but powered by a turbojet.
The dye cell is usually side-pumped, with one or more flashtubes running parallel to the dye cell in a reflector cavity. The reflector cavity is often water cooled, to prevent thermal shock in the dye caused by the large amounts of near-infrared radiation which the flashtube produces. Axial pumped lasers have a hollow, annular-shaped flashtube that surrounds the dye cell, which has lower inductance for a shorter flash, and improved transfer efficiency. Coaxial pumped lasers have an annular dye cell that surrounds the flashtube, for even better transfer efficiency, but have a lower gain due to diffraction losses.
Below the ring-like annular zone the stem is nattered; above, it is white and smooth. The cap of H. olivaceoalbus is wide and is hemispherical in young fungi; they become flatter and wider with age, but they keep their characteristic dark umbo. Underneath the slimy grey to sooty-brown surface, the cap cuticle is streaked with fine, dark grey radially arranged fibers. Young fruit bodies are covered by two velum layers; the inner velum, composed of dark fibrils, becomes a ring or sheath (annular zone) on the stem that is covered by the gelatinous outer layer.
As a general rule, the A1, A3, and A5 pulleys in the fingers are "joint pulleys" that originate from the volar plate on the volar aspect of the metacarpophalangeal, proximal interphalangeal, and distal interphalangeal joints, respectively. The A2 and A4 pulleys arise from the periosteum on the proximal half of the proximal phalanx and the mid portion of the middle phalanx, respectively. The first annular pulley (A1 pulley), near the head of the metacarpal bone, lies in the flexor groove in the deep transverse metacarpal ligament. In the thumb there are two annular pulleys and a single oblique pulley.
Postnatal diagnostic procedures include abdominal x-ray and ultrasound, CT scan, and upper GI and small bowel series. Abdominal radiography can show the classic sign of the "double bubble": the presence of air in the stomach and duodenum. Unfortunately, this double-bubble sign is not pathognomonic for annular pancreas, as it can also be observed in other conditions, such as duodenal atresia and intestinal malrotation. Upper GI series may be suggestive of annular pancreas, especially if they show a duodenal narrowing of the second portion of the duodenum and the concomitant dilatation of the proximal duodenum.
Eclipse progression at the annular stage, seen from Minxiong, Chiayi, Taiwan The central path of this annular eclipse passed through parts of Central and Eastern Africa, including Congo Republic, DR Congo, the Central African Republic, South Sudan, Ethiopia, Eritrea, and Djibouti; the southern Arabian Peninsula, including Yemen, Oman, and southern Saudi Arabia; parts of South Asia and the Himalayas, including southern Pakistan, northern India, Nepal, and Tibet; parts of East Asia, including South China and Taiwan, and part of Micronesia, including Guam. A partial eclipse was visible throughout much of the rest of Africa, southeastern Europe, most of Asia (except the north part of Siberia and most of the island of Java), and in New Guinea and the north of Australia just before sunset. In Europe, the partial eclipse was visible for places southeast of the line roughly passing through Perugia, Miskolc, Lviv, and Yaroslavl. For Oman and India, it was the second annular eclipse 6 months after the December 2019 eclipse.
The most useful measures are the peak velocities, in systole S' and in early diastole (e') and late diastole during atrial contraction (a'). Annular velocities summarize the longitudinal contraction of the ventricle during systole, and elongation during diastole. Peak velocities are commonly used.

They usually come in clusters such as linear arrays. Less frequently, urticarial, nodular, or sometimes annular lesions may be appreciated. The dorsal aspect of the hands, face, elbows, and extensor portions of the extremities are most frequently affected. Mucosal lesions are absent.
The basal segment of the labium is very short and annular with the distal segment transverse and longer than the first segment. The palpifer is sclerotised and fused with the opposite palpifer to form a complete ring. The submentum is entirely membranous.
If a moon with same apparent diameter in this eclipse near the Aphelion, it will be Total Solar Eclipse, but in this time of the year, just 2 weeks and 4 days (18 days) before perihelion, it is an Annular Solar Eclipse.
Tropical Depression Tina dissipated on October 11, shortly after entering the Central Pacific Hurricane Center's area of responsibility. Although the tropical cyclone never made landfall, heavy rains were recorded across western Mexico. While at peak intensity, the storm also displayed annular characteristics.

Future total solar eclipses will cross the United States in April 2024 (12 states) and August 2045 (10 states), and annular solar eclipses—wherein the Moon appears smaller than the Sun—will occur in October 2023 (9 states) and June 2048 (9 states).
Urticarial allergic eruption is a cutaneous condition characterized by annular or gyrate urticarial plaques that persist for greater than 24 hours.Ackerman AB: Urticarial allergic eruption. In: Ackerman AB, ed. Histologic Diagnosis of Inflammatory Skin Diseases, 1st edn, Philadelphia: Lea & Febiger; 1978:181-183.
This annular solar eclipse was non-central. Instead, over half of the antumbral shadow fell off into space throughout the eclipse. Gamma had a value of 0.9992. Annularity was visible from northern Soviet Union (today's Russia) and Bear Island, the southernmost island of Svalbard, Norway.
This was the last of 57 umbral eclipses of Solar Saros 118. The 1st was in 947 AD and the 57th was in 1957. The total duration is 1010 years. While it was an annular solar eclipse, it was a non-central solar eclipse.
Thickest portion of capsule is annular region surrounding the anterior pole. This will also increases with age (from 13.5-16μm). Even though capsule is a highly elastic structure, it contains no elastic fibers. Elasticity is because of the thick lamellar arrangement of the collagen fibers.
The most important example of this style is the Sarre brooch, discovered in an Anglo-Saxon cemetery near Kent. It is intricately decorated with three- dimensional birds on the annular ring and on the pin. It currently can be found in the British Museum.
This event was a hybrid, starting and ending as an annular eclipse. The path of totality crossed central Russia, the Arctic Ocean, northeastern Ellesmere Island in Canada, Greenland, , and annularity crossed southern Siberia in Russia (now in northeastern Kazakhstan and southern Russia) and southern Greenland.
This event is a hybrid, starting and ending as an annular eclipse. The path of totality crossed the eastern Pacific Ocean, northwestern United States, and across central and eastern Canada, and northern Labrador of the Dominion of Newfoundland (today's Newfoundland and Labrador in Canada).
The cap is up to in diameter, convex in shape, sometimes with an umbo, and whitish in color. After being scratched or bruised, the cap turns yellow. The stipe is long by thick and bulbous. A large, white annular ring is present on the stipe.
The annular combustor has 16 air-blast fuel injection nozzles. The turbine that drives the compressor has two stages, with the first stage using single- crystal blades. A free power turbine with two stages drives the propeller through an inner shaft and a gearbox.
The annular eclipse commenced over the Chinese province of Hainan at sunrise, at 6:06 a.m. China Standard Time. Travelling northeast, antumbra of the eclipse approached and passed over the cities of Guangzhou, Hong Kong, and Xiamen, reaching Taipei, Taiwan by 6:10 a.m NST.
Occurring only 3.2 days after perigee (Perigee on Friday, August 18, 2017), the moon's apparent diameter was larger during the total solar eclipse on Monday, August 21, 2017. There was another solar eclipse in 2017, a large annular solar eclipse (99.223%) on February 26.
The radial collateral ligament is attached to the lateral epicondyle below the common extensor tendon. Less distinct than the ulnar collateral ligament, this ligament blends with the annular ligament of the radius and its margins are attached near the radial notch of the ulna.
Annular erythema of infancy is a skin condition reported in children roughly six months in age, characterized by transitory skin lesions that resolved without treatment within eleven months.James, William; Berger, Timothy; Elston, Dirk (2005). Andrews' Diseases of the Skin: Clinical Dermatology. (10th ed.). Saunders. .
High-angle annular dark-field imaging (HAADF) is an STEM technique which produces an annular dark field image formed by very high angle, incoherently scattered electrons (Rutherford scattered from the nucleus of the atoms) — as opposed to Bragg scattered electrons. This technique is highly sensitive to variations in the atomic number of atoms in the sample (Z-contrast images). For elements with a higher Z, more electrons are scattered at higher angles due to greater electrostatic interactions between the nucleus and electron beam. Because of this, the HAADF detector senses a greater signal from atoms with a higher Z, causing them to appear brighter in the resulting image.
A hole saw with pilot bit A diamond hole saw A hole saw (also styled holesaw), also known as a hole cutter, is a saw blade of annular (ring) shape, whose annular kerf creates a hole in the workpiece without having to cut up the core material. It is used in a drill. Hole saws typically have a pilot drill bit (arbor) at their center to keep the saw teeth from walking. The fact that a hole saw creates the hole without needing to cut up the core often makes it preferable to twist drills or spade drills for relatively large holes (especially those larger than ).
Phase plugs that interface with dome-type diaphragms include a wide variety: designs with radial slots, designs with concentric annular ring slots, and hybrid designs with a combination of annular and radial slots. Altec engineer Clifford A. Henricksen reported on the differences between radial and "circumferential" types of phase plugs at Audio Engineering Society conventions in 1976 and 1978. The radial design is easier to produce, but it does not differentiate between sound waves from the perimeter of the diaphragm and sound waves from the center. At high frequencies, the diaphragm does not act as a perfect piston; instead, it displays rippling, modal properties related to its stiffness and density.

The branch pipe is a penetrant, as is the plastic sleeve, which is a code violation if left in place, unless allowed by the certification listing with a firestop that permits such sleeving to be left in place. The space between the sleeve and the pipe is the annulus or annular space The annulus, or annular space, is the space between a penetrant and whatever surrounds it, such as the sides of an opening or a sleeve, as the case may be. Sometimes an annulus can be "offset", meaning that the penetrant is not centred.
Oblique Landsat image of Araguainha crater draped over digital elevation model (5× vertical exaggeration); screen capture from NASA World Wind Araguainha is a complex crater with annular and radial faults, exposed to the surface and eroded, cut through by the Araguaia River. The crater has an uplifted central core, shaped like an elliptical basin, consisting of exposed basement granite. Surrounding this core is a ring of shocked granite and overlying breccias; then another ring of ridges and mountains, in diameter and up to high, consisting of folded and steeply tilted Devonian sandstones. This central region is surrounded by an annular depression floored by rocks from Devonian and Carboniferous sandstone formations.
However, there was an annular region on either end where ions of the right energy could escape, and various calculations demonstrated the rate would be fairly high. By injecting electrons into the mirror before the fuel, the E-layer would create a second magnetic field that would cause the annular areas to fold back into the center of the tank. The resulting field was shaped like a tube, and very similar to the Field-Reversed Configuration, or FRC. The main difference between these devices is the way the field reversal is achieved; with the E-layer in the Astron, and by currents in the plasma for the FRC.
On the atolls an annular reef rim surrounds the lagoon, with several natural reef channels. A standard definition of an atoll is "an annular reef enclosing a lagoon in which there are no promontories other than reefs and islets composed of reef detritus".The northern part of the Funafuti lagoon has a deep basin (maximum depth recorded of 54.7 m) basin, and the southern part of the lagoon has very narrow shallow basin. The eastern shoreline of Fongafale in the Funafuti lagoon (Te Namo) was modified during World War II; several piers were constructed, beach areas filled, and deep water access channels were excavated.
NASA: Eclipses During 2010: Annular Solar Eclipse of January 15 At approximately 13:20 IST, the annular solar eclipse entered India at Thiruvananthapuram (Trivandrum), the capital of Kerala and exited India at Rameswaram, Tamil Nadu. The eclipse was viewable for 10.4 minutes in India. After Rameswaram, it entered Sri Lanka at Delft Island, exited at Jaffna in Sri Lanka, crossed the Bay of Bengal and re-entered India in Mizoram. Eclipse picture from Thiruvananthapuram, India where the eclipse was 94% Thiruvananthapuram, which was the entry point of the eclipse in India, was equipped with telescopes and announced facilities for the public to view the eclipse.
A general Annular Fluidized Bed (AFB) introduces gas at high speeds that enter the reactor from the bottom of the large central nozzle and additional fluidized gas is introduced through an annular nozzle ring. As a result, gas and solids are extensively mixed in the dense bottom part of the mixing chamber and flow upward in the riser. The gas and solids both leave the riser and are separated in a cyclone depending on the set velocities. The separated gas flows through a bag filter and the solids move downwards in the downer which is fed into the bottom of the plant which repeats the process again.
Influence of gas velocity in the Annular Fluidized Bed Bubbling occurs in the annular fluidized bed caused by the introduction of gas by the central nozzle at a certain velocity moves in the general upwards direction. The sudden eruption of gas at the central nozzle causes particles to be transport in the bubbles wake By increasing the velocity of the annulus results in an increase in the bubble size and the bubbling velocity. The new increase in bubble dynamics enables “the ejected solids to penetrate deeper into the central gas jet”. As a result of this, the concentration and velocity of solids increases and consequently the solid optimum mass flux increases.
These are among the largest plant-parasitic nematodes, reaching 1.5 to 3 millimeters in length. They are slender and cylindrical in shape with annular rings along their bodies. They have long, strong stylets. There are male and female individuals in each species, and they reproduce sexually.
The quadrate ligament is a fibrous band attached to the inferior border of the radial notch on the ulna and to the neck of the radius. Its borders are strengthened by fibers from the upper border of the annular ligament. The ligament is long, wide, and thick.
This relies on the exploitation of chromatic aberration (wavelength-dependence of focal length). Numerical modeling shows that chromatic aberration can yield useful chromatic information through the dependence of image acuity on accommodation. The unusual off-axis slit and annular pupil shapes in cephalopods enhance this ability.
The Mars Science Laboratory capsule, carrying the Mars rover Curiosity, descending under a ring parachute. Ribbon and ring parachutes have similarities to annular designs. They are frequently designed to deploy at supersonic speeds. A conventional parachute would instantly burst upon opening and be shredded at such speeds.
An annular eclipse will start in European Russia north-east of Moscow (passing through Yaroslavl, Vologda and Syktyvkar), will cross Arctic Ocean, Alaska, west part of Canada and will finish in the United States, crossing north-western states (Washington, Oregon, Wyoming, California, Nevada and Utah) respectively.
The path of annularity crossed Atlantic Ocean, Africa and Indian Ocean. This was the 47th solar eclipse of Solar Saros 125. The Sun was 95% covered in a moderate annular eclipse, lasting 7 minutes and 22 seconds and covering a broad path up to 232 km wide.
Paul Tracy was second-fastest for the day at 229.961 mph, and Fittipaldi was third at 229.264 mph. During the afternoon practice, an annular eclipse crossed over the state of Indiana, and the Speedway. Track temperatures cooled, and generally faster laps were observed during the phenomenon.

McLelland 2009, p. 41. Supersonic speeds also threatened inlet stability. The inlet's central shock cone served as a compression surface, diverting air into the annular inlet. As the Lightning accelerated through Mach 1, the shock cone generated an oblique shock positioned forward of the intake lip.
It was the 20th eclipse of the 145th Saros cycle, which began with a partial eclipse on January 4, 1639 and will conclude with a partial eclipse on April 17, 3009. The moon's apparent diameter was 7 arcseconds larger than the February 4, 1981 annular solar eclipse.
A double-cone is a surface of revolution, generated by a line. A 2-dimensional object with circular symmetry would consist of concentric circles and annular domains. Rotational circular symmetry has all cyclic symmetry, Zn as subgroup symmetries. Reflective circular symmetry has all dihedral symmetry, Dihn as subgroup symmetries.
A front anti-roll bar attached to the inboard extensions of the upper A-arms. The 804 was the first Porsche to come standard with disc brakes. The car used Porsche's unique annular ring system. The 804 was also the first Porsche equipped with rack- and-pinion steering.
For this article, annular velocity is described, as used in drilling fluid applications in the oil exploration industry. There may be other applications in other fields of study such as fluid mechanics (the study of the movement of fluid) or fluid dynamics (the study of the flow of fluid).
Thomas 2010, pp. 13–14. One Typhoon, R8694, was used by Napier for trials with the more powerful Sabre IV, cooled using an annular radiator and driving a four-bladed propeller. The new engine and radiator arrangement required substantial modifications to the forward fuselage and engine bearer structures.
The moon's apparent diameter was 4.8 arcseconds smaller than the January 25, 1963 annular solar eclipse. This was a total solar eclipse because occurred in July and July is near is aphelion (furthest apart to the Sun). The moon's apparent diameter was just over 2.2% larger than the Sun's.
Rift-sawing is a woodworking process that aims to produce lumber that is less vulnerable to distortion than flat sawn lumber. Rift-sawing may be done strictly along a log's radials—perpendicular to the annular growth ring orientation or wood grain—or as part of the quarter sawing process.
The fruit body has a long stem ranging from , a diameter of and a somewhat slimy surface in wet weather. It is often wavy or bent. The base of the stem is sometimes slimmer than near its apex. Above the annular zone, the stem is smooth and whitish.
The shell is sealed with a permanent calcareous plug at one end and (when the animal has withdrawn into the shell) with a circular, multispiral, horny operculum at the other end, the shell aperture. The sculpture is smooth or consists of a close-set, large number of annular ridges.
The tentacles are very close to the edge of the mouth. The head is slightly widened around the jaw angle and narrows anteriorly. The body has 312–318 annuli in total. The annular grooves are dorsally complete but narrowly separate ventrally, except for the last one tenth of body.
Cross-sectional representation of a non-transferred DC plasma torch. Showing the pointed cathode and annular anode. The inlets and outlets of the water-cooling system are labelled, note that the arc temperature can be up to 15 000°C. The plasma arc is drawn for illustration purposes only.
For DNB type of boiling crisis, the flow is characterized by creeping vapor fluid between liquid and the wall. On top of the convective heat transfer, radiation heat transfer contributes to the heat transfer. After the dryout, the flow regime is shifted from an inverted annular to mist flow.
The duration of annularity at maximum eclipse (closest to but slightly shorter than the longest duration) was 11 minutes, 36.56 seconds in the Atlantic Ocean north of Brazil. It was the longest annular solar eclipse since January 5, 1647, but the Solar eclipse of December 2, 1937 lasted longer.
The stipe is 3–8 cm long and 0.5 cm thick. It has an equal structure only enlarging near the base. The stipe is striate, pallid to yellow brown with fine fibrils that stain blue when handled. The stipe has a cortina that sometimes leaves a fragile annular zone.
Anus surmounted by a spoon shaped hood with a ventral opening, 20 fine annular rings and 14-20 long papillae along edge. On the ventral side of basis, two long cirrus, behind one unpaired longer cirri. .Kirkegaard, J. B. Danmarks Fauna 86, Havbørsteorme II. Copenhagen. Danmarks Naturhistoriske Forening, 1996.
In 1890, the Colchester millwright Bryant replaced the old wooden windshaft with the cast iron windshaft from the annular sailed mill at Roxwell. Bryant may have added the fantail at this time. Milling by wind ceased c1911. During World War I the mill was worked by steam alone.
Parthenolide undergoes trans-annular cyclization and elimination to form the guaianolide skeleton. The second pathway includes the enzymatic hydroxylation of (+)-costunolide followed by dehydration and cyclization to give the guaianolide skeleton. (Fig. 3) Further epoxiation of the guaianolide skeleton would yield the desired sesquiterpene lactone, arglabin. 605x605px Fig. 2.
Some species are dioecious, like Spinacia, Grayia, Exomis, and Atriplex. In several species of tribe Atripliceae, the female flowers are without perianth, but enclosed by two bracts. The species with a perianth have up to five tepals. The seed is horizontal or vertical, with annular or horseshoe-shaped embryo.
For integral membrane proteins spanning the thickness of the membrane bilayer, these annular/shell lipids may act like a lubricating layer on the proteins' surfaces, thereby facilitating almost free rotation and lateral diffusion of membrane proteins within the 2-dimensional expanse of the biological membrane(s). Outside the layer of shell/annular lipids, lipids are not tied down to protein molecules. However, they may be slightly restricted in their segmental motion freedom due to mild peer pressure of protein molecules, if present in high concentration, which arises from extended influence of protein-lipid interaction. Membrane areas away from protein molecules contain lamellar phase bulk lipids, which are largely free from any restraining effects due to protein-lipid interactions.
Using a composite fan case will also reduce weight. The high pressure (HP) compressor is up to 2% more efficient. As the GE90 fan left little room to improve the bypass ratio, GE looked for additional efficiency by upping the overall pressure ratio from 40 to 60, focusing on boosting the high-pressure core's ratio from 19:1 to 27:1 by using 11 compressor stages instead of 9 or 10, and a third-generation, twin-annular pre-swirl (TAPS) combustor instead of the previous dual annular combustor. Able to endure hotter temperatures, ceramic matrix composites (CMC) are used in two combustor liners, two nozzles, and the shroud up from the CFM International LEAP stage 2 turbine shroud.
It underwent an eyewall replacement cycle as it turned to the west-northwest, temporarily halting its intensification trend, before quickly strengthening and attaining major hurricane status on July 20. Later that day, Hurricane Daniel organized into a very symmetric cyclone with a distinct eye about 30 miles (45 km) in diameter. Upon attaining Category 4 status on the Saffir- Simpson Hurricane Scale, the cyclone resembled the appearance of an annular hurricane; an annular hurricane is one with a large and symmetric eye, surrounded by a thick ring of intense convection, and usually is able to maintain its intensity and structure for several days. On July 21 the hurricane underwent another eyewall replacement cycle.
In 1924 he went to work for the Science Museum, London and remained there until his retirement in 1954. During his time there a model of a Lee-Richards annular monoplane was commissioned and put on display. He also wrote The History and Development of Typewriters, Science Museum, London, 1938.

Bagnold's fluid refers to a suspension of neutrally buoyant particles in a Newtonian fluid such as water or air. The term is named after Ralph Alger Bagnold, who placed such a suspension in an annular coaxial cylindrical rheometer in order to investigate the effects of grain interaction in the suspension.
Approximations to Bessel beams are made in practice either by focusing a Gaussian beam with an axicon lens to generate a Bessel–Gauss beam, by using axisymmetric diffraction gratings, or by placing a narrow annular aperture in the far field. High order Bessel beams can be generated by spiral diffraction gratings.

Rhizomatous root system relatively dense and shallow, penetrating to a depth of only 10–20 cm, but often spreading to form substantial clump. Habitat: light shade of upland forest on calcareous rocks and screes.
This eclipse occurred two days after the RMS Titanic sank in the northwestern Atlantic Ocean under the darkness of new moon.www.astronomeer.com: The "Titanic" eclipse of 17 April 1912 The last annular eclipse in the Netherlands was 17 April 1912, just two days after the Titanic hit an iceberg and sank.
The protoxylem was probably inside the xylem, maturing from the inside out. The tracheids have annular secondary wall thickening. Round- to kidney-shaped sporangia lie on dichotomous branches at the end of the lateral branches, and open with symmetrical valves. The trilete spores are 18 to 36 µm in size.
The circular air inlet behind the reduction gear has a de-icing device using hot air. The compressor's two axial stages use blisks. The shaft runs on ball bearings. Air flow through the annular combustion chamber is S-wise, with fuel being added in radial direction by a rotating atomizer disc.
The entry is from the south side through the wooden door from late 19th century. In the vestibule, there is a cross- shaped vault as well as in the church. The church is divided into three naves by two pairs of columns with polygonal pedestals. The sacristy has an annular vault.
If no fluid is moving, the well is static. The bottom hole pressure (BHP) is equal to the hydrostatic pressure (HP) on the annular side. If shut in on a kick, bottom hole pressure is equal to the hydrostatic pressure in the annulus plus the casing (wellhead or surface pressure) pressure.
The seed contains an annular, horseshoe-shaped or folded embryo that surrounds the perisperm. The fruiting perianth remains either unappendaged or develops 5 wings. The wings are spiny in Bassia hyssopifolia. According to its most recent description, the genus is defined by its three types of C4 "kochioid" leaf anatomy.
2000 also marked the year that the concept of a loud side and a quiet side was replaced by the rule that large scale sound camps would be placed at the 10:00 and 2:00 edges, facing out into the deep playa. Extra annular streets have been added as need has increased.
2010 Mar;11(2):149-56. Epub 2009 Dec 3 The method measures annular velocities to and from the probe during the heart cycle. Single spectral tissue velocity curve from the mitral annulus. The curve shows velocities towards the probe (positive velocity) in systole, and away from the probe (negative velocities) in diastole.
In 1991, a case was reported of a man having plaque psoriasis and treating it with UV radiation at a tanning salon. After receiving a partial thickness burn from overexposure, he presented with annular pustular psoriasis, which cleared after 21 days, only to reoccur every 3 to 6 weeks for a year.
CNT Laurel wreaths are sometimes used in heraldry. They may be used as a charge in the shield, around the shield, or on top of it like an annular form. Wreaths are a form of headgear akin to circlets. In heraldry, a twisted band of cloth holds a mantling onto a helmet.
Functionally equivalent myelin-like sheaths are found in several invertebrate taxa including oligochaetes, penaeids, palaemonids, and calanoids. These myelin-like sheaths share several structural features with the sheaths found in vertebrates including multiplicity of membranes, condensation of membrane, and nodes. However, the nodes in vertebrates are annular; i.e. they encircle the axon.
An annular eclipse will start on the north of Africa and will cross Eurasian continent, will cross Algeria, Tunisia, Libya, Malta, Greece, Bulgaria, Ukraine, Russia, Kazakhstan, China and Japan. An eclipse will pass through lot of large cities such as Tripoli, Athens, Istanbul, Krasnodar, Rostov-on-Don, Volgograd, Omsk, Krasnoyarsk and Sapporo.
Its geometrical parameters were R = 3.6 mm, r = 2.5 mm, w = 0.2 mm, t = 0.9 mm. R and r are used in annular parameters, w is the spacing between the rings and t = the width of the outer ring. The material had a thickness of 1.6 mm. Permittivity was 3.85 at 4 GHz.
For a fluid moving between two plane parallel surfaces—where the width is much greater than the space between the plates—then the characteristic dimension is equal to twice the distance between the plates. This is consistent with the annular duct and rectangular duct cases above taken to a limiting aspect ratio.
The tube is short and campanulate, with an annular, crenulate disk inside at the base. The calyx lobes oblong and mucronate, without a dorsal keel. The corolla is a vibrant candy pink, or rarely white, setting off the vivid yellow anthers. The corolla tube is as long as the calyx or slightly longer.
Stipules of terminal buds eventually leave annular scars. The glossy and very dark elliptic leaves have a prominent driptip, and measure up to 14 cm long. They are glossy below, and have two small lobes at the base. The flowers appear in spring and are arranged in a whitish to mauve puff.
The radial notch of the ulna (lesser sigmoid cavity) is a narrow, oblong, articular depression on the lateral side of the coronoid process; it receives the circumferential articular surface of the head of the radius. It is concave from before backward, and its prominent extremities serve for the attachment of the annular ligament.
The storm exhibited winds of as it passed within of the island. After completing the cycle on July 16, Dolores exhibited annular characteristics, with a symmetric and wide eye. The NHC described the eyewall as thick and "donut-shaped". Re-strengthening did not commence, as Dolores had moved over cooler sea surface temperatures.
The engine employs a simple thrust vectoring system that uses four swiveling nozzles, giving the Harrier thrust both for lift and forward propulsion, allowing for STOVL flight. Combustion system is an annular combustor with ASM low-pressure vaporising burners. Engine starting was by a top-mounted packaged combined gas turbine starter/APU.
The 12 LAV stations are constructed from four or five annular rings of lead glass scintillator detectors surrounding the decay volume. The first 11 stations are operated in the same vacuum tank as the decay volume and STRAW while the final chamber (LAV12) is positioned after the RICH and operated in air.
Partial solar eclipse of September 22, 2006 (of annular event) from São Paulo, Brazil, member 16, of Saros series 144 Saros cycle series 144 for solar eclipses occurs at the Moon's descending node, repeating every 18 years, 11 days, containing 70 events. All eclipses in this series occurs at the Moon’s descending node.
They incorporate a feature called Annular Fuel Discharge, which greatly reduces the likely-hood of hesitation and flat spots under acceleration. They use the standard Holley bolt pattern (same as Holley two barrels). Size is determined by the diameter of the venturii. This can be found cast into the float chamber side.
Specimens from Costa Rica measure in total length and have 85–102 primary and 11–26 secondary annuli; the annular grooves lack dark pigment seen in Dermophis mexicanus and Dermophis oaxacae. The body is slender. The eyes can be seen through the skin. The head is pinkish, contrasting with the purplish-gray body.
Profile view of a laser Lightcraft type 200 First small-scale models used laser propulsion which is a technique still in early stages of development. Lightcraft prototypes are made of solid aluminium machined axisymmetrically. The nose is shaped as a blunted cone for aerodynamical purpose. The rim has an annular air inlet.
This type of overhead crane has one end of the bridge mounted on a fixed pivot and the other end carried on an annular track; the bridge traverses the circular area beneath. This offers improvement over a jib crane by making possible a longer reach and eliminating lateral strains on the building walls.
Dioscoreales are vines or herbaceous forest floor plants. They may be achlorophyllous or saprophytic. Synapomorphies include tuberous roots, glandular hairs, seed coat characteristics and the presence of calcium oxalate crystals. Other characteristics of the order include the presence of saponin steroids, annular vascular bundles that are found in both the stem and leaf.
Expansion of the annulus can result in leaflets that do not join soundly together, leading to functional mitral regurgitation. The normal diameter of the mitral annulus is , and the circumference is . Microscopically, there is no evidence of an annular structure anteriorly, where the mitral valve leaflet is contiguous with the posterior aortic root.
The 218B could be certified in early to mid-1996. The new engine, dubbed the "8000", was to feature a new fan of increased diameter (by 1.7 in), extended exhaust cone, a larger LP compressor, a new annular burner, and a new LP turbine and mixer. The initial thrust rating would be around .
"Episode 6646", also known as "The Eclipse", is the 6646th episode of the Australian soap opera Neighbours. It premiered on Eleven on 20 May 2013. The episode was written by Jason Herbison and directed by Laurence Wilson. "Episode 6646" revolves around an annular eclipse, which changes the lives of several Ramsay Street residents.
The eclipse was visible as only a partial eclipse in much of Africa, Eastern Europe, the Middle East and Asia. It was seen as an annular eclipse within a narrow stretch of width across Central Africa, Maldives, South Kerala (India), South Tamil Nadu (India), Sri Lanka and parts of Bangladesh, Burma and China.
Simple venturis have fixed throat areas and so will only operate efficiently over a certain range of flow rates. Adjustable- throat venturis allow efficiency to be maintained over a much larger range of flows by changing the size of the throat in accordance with the gas flow rate. Certain types of orifices (throat areas) that create more turbulence than a true venturi were found to be equally efficient for a given unit of energy consumed and the results of these findings led to the development of the annular-orifice, or adjustable-throat, venturi scrubber (Figure 5). The size of the throat area is varied by moving a plunger, or adjustable disk, up or down in the throat, thereby decreasing or increasing the annular opening.
The annular ligament binds the head of the radius to the radial notch of the ulna, preventing any separation of the two bones laterally. Therefore, the humeroradial joint is not functionally a ball and socket joint, although the joint surface in itself allows movement in all directions The annular ligament secures the head of the radius from dislocation, which would otherwise tend to occur, from the shallowness of the cup-like surface on the head of the radius. Without this ligament, the tendon of the biceps brachii would be liable to pull the head of the radius out of the joint. The head of the radius is not in complete contact with the capitulum of the humerus in all positions of the joint.
The annular ligament is attached by both its ends to the anterior and posterior margins of the radial notch of the ulna, together with which it forms the articular surface that surrounds the head and neck of the radius. The ligament is strong and well defined, yet its flexibility permits the slightly oval head of the radius to rotate freely during pronation and supination. The head of the radius is wider than the bone's neck, and, because the annular ligament embraces both, the radial head is "trapped" inside the ligament which thus acts to prevent distal displacement of the radius. Superiorly, the ligament is supported by attachments to the radial collateral ligament and the fibrous capsule of the elbow joint.
The anterior ligament of the elbow is a broad and thin fibrous layer covering the anterior surface of the joint. It is attached to the front of the medial epicondyle and to the front of the humerus immediately above the coronoid and radial fossae below, to the anterior surface of the coronoid process of the ulna and to the annular ligament, being continuous on either side with the collateral ligaments. Its superficial fibers pass obliquely from the medial epicondyle of the humerus to the annular ligament. The middle fibers, vertical in direction, pass from the upper part of the coronoid fossa and become partly blended with the preceding, but are inserted mainly into the anterior surface of the coronoid process.
A full-size manned glider proved successful. Model tests of a new design at the National Physics Laboratory gave promising results, confirming that an annular monoplane would be aerodynamically stable and have benign stalling characteristics. Through 1913-14 three monoplanes were built and flown. All were stable in flight and successively showed improved handling.
Replica images of a partial solar eclipse. A pinhole camera effect can sometimes occur naturally. Small "pinholes" formed by tree leaves will create replica images of the sun on flat surfaces. During an eclipse, this produces small crescents in the case of a partial eclipse, or hollow rings in the case of an annular eclipse.
The size of the stapes, compared with a 10-cent euro coin. The stapes is the third bone of the three ossicles in the middle ear. The stapes is a stirrup-shaped bone, and the smallest in the human body. It rests on the oval window, to which it is connected by an annular ligament.
The wingspan is 43–44 mm. The forewings are grey-whitish with a few fuscous and blackish scales. These form a dark streak along the fold not reaching the tornus, and a median streak from one-fifth to four-fifths. There is an ochreous grey annular mark at three-fifths interrupting the median streak.
Page 1170. . In the skin, this process leads to the abnormal replacement of annular squames with nucleated cells. Parakeratosis is associated with the thinning or loss of the granular layer and is usually seen in diseases of increased cell turnover, whether inflammatory or neoplastic. Parakeratosis is seen in the plaques of psoriasis and in dandruff.
Patterns of this "ring cent" were struck in various metals and with various hole sizes. There were also various different designs, with some designs lacking a date or a reverse design. Some did not even have a hole, in its place being a circle resembling a line for perforation. These were known as annular cents.
Armament was the specified single synchronised Vickers machine gun, with two 65 lb bombs carried internally. The Hispano-Suiza engine was enclosed in an annular cowling and drove a two-bladed propeller. Flat-bottomed pontoon-type floats were fitted, which were angled outwards to divert spray away from the engine and propeller.Mason 1992, p. 109.
This is the annular Soddy's hexlet (Figure 2). Six spheres s1-s6 may be packed around c and likewise sandwiched between the bounding planes a and b. Re- inversion restores the three original spheres, and transforms s1-s6 into a hexlet for the original problem. In general, these hexlet spheres S1-S6 have different radii.
These contain a concentric internal cylinder. This gathers pre-heated air from the cooling zone, which is then used to pressurize the middle annular zone of the kiln. Air spreading outward from the pressurized zone causes counter-current flow upwards, and co-current flow downwards. This again produces a long, relatively cool calcining zone.
The Lyulka TR-3A was redesignated as the AL-5 to honor Arkhip Mikhailovich Lyulka in 1950. It was a single-shaft turbojet with a seven-stage axial compressor. It had an annular combustion chamber with 24 nozzles and a single-stage turbine. It had a fixed exhaust nozzle and had a turbine starting unit.
Arena firing of continuous-rod warhead, 1972 at Naval Air Weapons Station China Lake. A continuous-rod warhead is a specialized munition that exhibits an annular blast fragmentation pattern, so that when it explodes it spreads into a large circle that cuts the target. It is used in anti-aircraft and anti-missile missiles.
All pump pressure does is "fill in the hole" and refresh the oil in the annular space faster than the leak expels it. This is why low-speed engines have relatively large journals, with only modest pump size and pressure. Low pressure indicates that leakage from the bearings is higher than the pump's delivery rate.
The VCP-1 was powered by a Wright-built Hispano-Suiza 8 V-8 engine and had tapered single-bay biplane wings. The fuselage was a monocoque structure constructed of plywood, while the wings were of wood and fabric construction. The engine was cooled with an unusual annular radiator.Green and Swanborough 1994, p. 193.
Between 1966 and 1989 a facility for launching sounding rockets was established near the town. The first launches were performed from Koroni on May 20, 1966 for investigation an annular solar eclipse. These rockets reached an altitude of 114 kilometers. From 1972 to 1989 several Russian meteorological rockets of M-100 type were launched.
Brooch styles were predominantly circular by the middle to late Anglo-Saxon era. During this time period, the preferred styles were the annular and jewelled (Kentish) disc brooch styles. The circular forms can be divided generally into enamelled and non-enamelled styles. A few non-circular style were fashionable during the eighth through eleventh centuries.
The quoit brooch combines the annular and penannular form with a double ring, and is intricately decorated. The descriptive name originates from the rings thrown in the game of Quoits. The earliest of these jewellery items were large, opulent silver brooches made in Kent in the mid-fifth century. The quoits were probably worn alone.
The three-dimensional crystal structure of a decameric, annular ribonucleoprotein complex of the RSV nucleoprotein (N) bound to RNA has been determined at 3.3 Å resolution. This complex mimics one turn of the viral helical nucleocapsid complex. Its crystal structure was combined with electron microscopy data to provide a detailed model for the RSV nucleocapsid.
Crossopetalum taxa are shrubs or trees, with opposite or whorled persistent leaves with petiole and stipules. Inflorescences are axillary, regrouping white, pale green, reddish, or purplish radially symmetric flowers, with four sepals, four petals, and a four-carpellate pistil. Intrastaminal nectaries are annular and fleshy. Fruits are red drupes, with one-two seeds per fruit.
The hurricane retained annular characteristics for about 48 hours before moving over cooler water. On August 28, it weakened to a tropical storm, and early on August 30, Howard was considered to have dissipated. A small, low-level swirl of clouds devoid of convection persisted for a few days before dissipating. Howard never affected land.
Thus, early marine engines are classified mostly according to their connection mechanism. Some common connection mechanisms were side-lever, steeple, walking beam and direct-acting (see following sections). However, steam engines can also be classified according to cylinder technology (simple-expansion, compound, annular etc.). One can therefore find examples of engines classified under both methods.
Sergio traveled towards the west and west-southwest throughout this period. The cyclone went through a third eyewall replacement cycle on October 8 as it tracked northeastward. Sergio acquired annular characteristics as it weakened slightly during the next couple of days. The storm then quickly weakened as it was propelled towards the Baja California Peninsula.
Resistance of an annular ring of material having a surface resistance of η per square. The radius of the outer surface of the inner electrode (yellow) is r. The radius of the inner surface of the outer electrode (magenta) is r. In the case of a coaxial cable, there is a closed-form solution.
Urticarial erythema multiforme is an unusual reaction virtually always associated with antibiotic ingestions, characterized by skin lesions that consist of urticarial papules and plaques, some of which clear centrally forming annular lesions, but with no true urticarial lesions.James, William; Berger, Timothy; Elston, Dirk (2005). Andrews' Diseases of the Skin: Clinical Dermatology. (10th ed.). Saunders. .
In his design, Center Camp remained the starting point, with two angular arms reaching out on either side to form a shallow "V" shape around the Man. These main arms consisted of six annular roads, and two outlying plazas. 1997 is the first year of a Ranger-patrolled perimeter, and also the first year of one entry gate.

Annular hurricanes have been simulated that have gone through the life cycle of an eyewall replacement. The simulations show that the major rainbands will grow such that the arms will overlap, and then it spiral into itself to form a concentric eyewall. The inner eyewall dissipates, leaving a hurricane with a singular large eye with no rainbands.
TAPS –A 4th Generation Propulsion Combustor Technology for Low Emissions. AIAA/ICAS International Air and Space Symposium and Exposition: The Next 100 Years, 14–17 July 2003, Dayton, Ohio. AIAA 2003–2657. The analytical tools developed for TAPS have also been used to improve other combustors, notably the single-annular combustors in some CFM56-5B and -7B engines.
On August 8, the JTWC upgraded Lekima to a super typhoon, and stated that the system had acquired some of the annular characteristics. Later that day, the JMA stated that Lekima attained maximum sustained winds of . At the same time, Lekima passed between Miyako-jima and Tarama-jima. Shortly thereafter, Lekima began an eyewall replacement cycle.
Hematopoietic cells (present in the liver in greater numbers before birth than afterward), Kupffer cells, and connective tissue cells originate in the mesoderm. The pancreas develops from a ventral bud and a dorsal bud that later fuse to form the definitive pancreas. Sometimes, the two parts surround the duodenum (annular pancreas), causing constriction of the gut.
A Heavy Duty Magnetic Drilling Machine Performing Drilling On Mild Steel Of Thickness 100 mm. A magnetic drilling machine is a portable drilling machine with a magnetic base (either electromagnetic or permanent magnet). It can use twist drill bits, annular cutters, milling cutters, and other rotary cutters. With suitable bits it can also tap threads, ream, and countersink.
The concept of Kuṇḍalinī is mentioned in the Upanishads (9th – 7th centuries BCE). The Sanskrit adjective ' means "circular, annular". It is mentioned as a noun for "snake" (in the sense of "coiled") in the 12th-century Rajatarangini chronicle (I.2). ' (a noun meaning "bowl, water-pot" is found as the name of a Nāga (serpent deity) in Mahabharata 1.4828).
The beautiful annular discs > which surround the mouth are three-quarters of an inch in diameter. :b.In Nepenthes of Mount Kinabalu, Shigeo Kurata gives a different derivation for the name: "The specific epithet edwardsiana refers to S. Edwards—a botanical draughtsman, who made many drawings for the Botanical Magazine." :c.Macfarlane's revised description of N. edwardsiana from 1908 reads: > 26\.
A pulled elbow typically results from a sudden pull on an extended arm. This may occur when lifting or swinging a child by the arms. The underlying mechanism involves slippage of the annular ligament off of the head of the radius followed by the ligament getting stuck between the radius and humerus. Diagnosis is often based on symptoms.
One of the largest impact crater lakes is Lake Manicouagan in Canada; the crater is a multiple-ring structure about across, with its diameter inner ring its most prominent feature; it contains a diameter annular lake, surrounding an inner island plateau, René-Levasseur Island. It is Earth's sixth-largest confirmed impact crater according to rim-to-rim diameter.
Genetic testing should be considered with adrenocortical carcinoma; carcinoid tumors; diffuse gastric cancer; fallopian tube/primary peritoneal cancer; leiomyosarcoma; medullary thyroid cancer; paraganglioma/pheochromocytoma; renal cell carcinoma of chromophobe, hybrid oncocytic, or oncocytoma histology; sebaceous carcinoma; and sex cord tumors with annular tubules. Primary care physicians can identify people who are at risk of heridatary cancer syndrome.
The gamosepalous green sepals consist of ovate lobes, and are distributed in one whorl. The annular disk is hypogynous. The five gamesepalous petals have oblong or ovate lobes and are disposed in one whorl. The corolla lobes overlapping to the left (such as A. rostrata) or to the right (such as A. macrophylla) in the bud.
The Trent 700 is an axial flow, high bypass turbofan with three coaxial shafts. The fan has 26 Wide Chord Blades and is powered by a 4-stage low pressure turbine. The 8-stage IP compressor and 6-stage HP compressor are both driven by a single stage turbine. The single annular combustor has 24 Spray Nozzles.
Another design uses a single open pipe to flow water downward. The water then returns through the annular gap between the pipe and the casing. This design provides better thermal contact than u-tubes, but risks contamination by groundwater. Since this involves practically no downhole equipment, these systems usually only go by the name of borehole heat exchangers (BHT).
Pages 388-389. . A post office operated at Requa 1878–1970, with closures in 1883 and moves in 1895 and 1898. The name is a version of the original Native American settlement, Rekwoi. On May 20, 2012, Requa was the first town on the North American continent to experience an annular eclipse from the centerline since May 10, 1994.
The annular snap-fit utilizes hoop-strain to hold into place. Hoop-strain is the expansion of the circumference of the more elastic piece as it is pushed onto the more rigid piece. In most cases the design is circular. Some popular examples are pen caps, ball and socket joints, snap fasteners and some water bottle caps.
The Chinese Future Giant Telescope has a primary focal ratio of 1.2. Its primary mirror is segmented with 1020 annular submirrors arranged in 17 concentric annuli. Each segment has average length and width both of 0.8 m. Apart from a conventional Cassegrain focus, four Nasmyth foci on two double-deck platforms on both sides are also present.
The Lyulka TR-3 was a single- shaft turbojet with a seven-stage axial compressor. It had an annular combustion chamber with 24 nozzles and a single-stage turbine. It had a fixed exhaust nozzle and had a pneumatic SV-3 starting unit, although this was later replaced by a turbine unit. It had a thrust of .
Atomic resolution scanning transmission electron microscopy image of La0.7Sr0.3MnO3, using an annular dark field detector. Overlay: lanthanum/strontium (blue), manganese (purple), oxygen (red). Lanthanum strontium manganite (LSM or LSMO) is an oxide ceramic material with the general formula La1−xSrxMnO3, where x describes the doping level. It has a perovskite-based crystal structure, which has the general form ABO3.
Francisco slowly weakened as it underwent an eyewall replacement cycle. At noon on October 21, Francisco rapidly weakened to a Category 3 typhoon and became an annular typhoon. Very early on October 22, Francisco entered the Philippine area of responsibility and it was given the name Urduja, as convection around Francisco started to weaken later that day.
The first pharyngeal pouch syndrome associates middle ear anomalies to the malleus and incus structures as well as to the non-differentiation of the annular stapedial ligament. Temporal bone and ear canal anomalies are also related to this structure of the ear and are known to be associated with sensorineural hearing loss and conductive hearing loss.
In fruit, the glomerules of flowers form connate hard clusters. The fruit (utricle) is enclosed by the leathery and incurved perianth, and is immersed in the swollen, hardened perianth base. The horizontal seed is lenticular, 2–3 mm, with a red-brown, shiny seed coat. The seed contains an annular embryo and copious perisperm (feeding tissue).
Other compact alternatives to the return connecting rod or trunk engines were Maudslay's siamese engine and the rare annular piston engine. Like the trunk engine, these placed the gudgeon pin within the length of the piston stroke by having a pair of pistons and a T-shaped crosshead that could relocate the gudgeon pin behind its usual position.
This nudibranch is translucent white in colour and reaches 30 mm in length. The tips of the rhinophores, oral tentacles and tail are dusted with white. The digestive gland in the cerata is dark brown, green or possibly red and there is no pigment on the surfaces of the cerata. The rhinophores have small annular wrinkles.
A flying gyroscope (also known as a flying cylinder or flying tube) is a cylindrical wing or annular airfoil. It is thrown like a football, and can fly very far. The William Mark Corporation invented their flying gyroscope, X-Zylo, in 1993. It was invented by Mark Forti, a Baylor University student, and refined within the aerospace industry.
BOP stacks frequently utilize both types, typically with at least one annular BOP stacked above several ram BOPs. Blowout preventers are used on land wells, offshore rigs, and subsea wells. Land and subsea BOPs are secured to the top of the wellbore, known as the wellhead. BOPs on offshore rigs are mounted below the rig deck.

Stem of the order of several mm to several cm in diameter and several cm to a metre long, erect or arched, dichotomizing occasionally, furnished with true roots at the base. Vascular bundle actinostele, tracheids of primitive annular or helical type (so-called G-type). Leaves are unbranched thorn-shaped (i.e.
The reverse-flow single-annular combustor resembles the GE-Honda HF120 design. The two-stage single-crystal high pressure turbine will be the first in this class of engines to be fully cooled. The three-stage low-pressure turbine is contra- rotating. A FADEC integrated propulsion control system will govern both engine and propeller pitch as an entire system.
Sepals free, greenish, persistent. Petals present or absent, often partly adnate to the nectary disk, equal to the sepals or shorter, white or greenish, usually larger in staminate than in pistillate flowers. Disk present, extrastaminal; annular or divided into alternisepalous segments or glands. Stamens opposite the sepals, free or fused for up to 9/10 of their length.
An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. Totality of this eclipse was not visible on any land, while annularity was visible in southern Argentina, Gabon, Equatorial Guinea, Cameroon, Central African Republic, Sudan (part of the path of annularity crossed today's South Sudan), Ethiopia, Djibouti and northern Somalia.
These boilers had a long life and required little expense in repairs. Five cross-stays were fitted in the steam space above the firebox. The safety valves were arranged above the firebox inside the cab, while a steam escape pipe was fitted above the valves and passed through the roof. The exhaust had an Adams' Vortex pattern annular nozzle.
The vertically or horizontally orientated seed has a brown to yellowish-brown, thin membranous seed coat. The annular embryo surrounds the copious farinaceous perisperm. The flowering time is March to June. The chromosome numbers are 2n = 18 (for the diploid Grayia arizonica and Grayia brandegeei) and 2n = 36 (for the tetraploid Grayia spinosa and Grayia plummeri).
The cyclone is an integral part of an annular fluidized bed, particular sized particles are separated by varying the velocity of feed gas. Consequently, at high velocity gas provides enough kinetic energy to separate particles from the fluidized bed. The feed gas and small particles fly into a cyclone separator and there the feed- gas and particles are separated.
An annular fluidized bed (AFB) can have a wide range of applications due to its ability to be used in conjunction with other fluidized bed type. The AFB is ideal for applications that require a fast and efficient heat and mass transfer with intense mixing. These applications can range from dryers, heat exchangers, heaters, coolers and reactors.
Bruniquel Cave is an archeological site near Bruniquel, in an area that has many paleolithic sites, east of Montauban in southwestern France. Annular (ring) and accumulation (pile) structures made of broken stalagmites have been found 336 metres from the cave entrance. Traces of fire were also found. The constructions have been dated to around 176,000 years ago.
Annularity was visible in Indonesia, Palau (Kayangel Atoll), Northern Mariana on June 11th (Tuesday), and the western tip of Jalisco, Mexico on June 10th (Monday). This eclipse was during the 2002 FIFA World Cup. The closest apogee occurred on June 4, 2002. It was the first annular solar eclipse visible in the Pacific in 6 months.
The cylindrical Hall thruster more readily lends itself to miniaturization and low-power operation than a conventional (annular) Hall thruster. The primary reason for cylindrical Hall thrusters is that it is difficult to achieve a regular Hall thruster that operates over a broad envelope from ~1 kW down to ~100 W while maintaining an efficiency of 45-55%.
Suillus grevillei (commonly known as Greville's bolete and larch bolete) is a mycorrhizal mushroom with a tight, brilliantly coloured cap, shiny and wet looking with its mucous slime layer. The hymenium easily separates from the flesh of the cap, with a central stalk that is quite slender. The species has a ring or a tight-fitting annular zone.
Hover efficiency vs disc loading for different configurations An annular lift fan aircraft is a conceptual vertical takeoff and landing (VTOL) aircraft that was first systematically and numerically investigated in 2015. This concept was proposed to offer a VTOL solution for both high hovering efficiency and high cruise speed, using a large annular lift fan instead of the relatively small conventional circular lift fans used in the Ryan XV-5 Vertifan and the F-35B Lightning II (JSF). Single-stage lift fan aircraft with an inner fan and an outer fan coupled by the gears in the baffle Disc loading vs. power loading for VTOL aircraft The Ryan XV-5 and the F-35B use relatively smaller lift fans, either fan-in-fuselage or fan-in-wing, with very high disc loading.
In some cases it is possible to have signs of inverse peristalsis of the duodenal tract which is proximal to the narrowing caused by the annular pancreas, and the dilatation of the duodenal portion distal to the anomaly. An abdominal CT scan or an MRI allows to highlight the narrowing of the descending duodenal tract and the ring of pancreatic tissue surrounding the duodenum: this ring can be complete or, in patients with an incomplete annular pancreas, extended in a postero-lateral or anterolateral direction with respect to the second part of the duodenum. ERCP or MRCP with secretin allow precise delineation of the anatomical structure and in particular a good visualization of pancreatic ducts, as well as a careful analysis of pancreatic secretion into the duodenum lumen.
Typhoon Noru slowly weakening with annular features south of Japan on August 3 On July 31, Noru reached its peak intensity at around 00:00 UTC with ten-minute sustained winds at 175 km/h (110 mph) and the central pressure at 935 hPa (27.61 inHg). It remained an impressively annular system with a clear eye but lacking banding features, yet the JTWC downgraded it to a typhoon in the afternoon because of recently warming cloud tops. Traveling northwestward over an area of low ocean heat content and isolated from well-defined outflow, Noru's gradual weakening trend became more evident early on the next day, which is also indicated by the JMA. A microwave imagery depicted a weakened eyewall, while the eye was temporarily not as clear as before.
Mature caps develop characteristic yellowish spots. A wispy, rusty brown annular zone is visible on the upper stem. The cap is initially bell-shaped before becoming broadly convex and then flat in maturity (sometimes retaining a broad umbo), and attains a diameter of . The cap surface is slimy (in wet weather) and smooth, and has a lilac or purplish color.

USGS Professional Paper: 1348, Chapter 8. (online) This basin has received the unofficial designation 'Schiller Annular Plain' among lunar observers.
Peak systolic annular velocity (S') of the left ventricle is as close to a contractility measure as you can get by imagingThorstensen A, Dalen H, Amundsen BH, Støylen A.Peak systolic velocity indices are more sensitive than end-systolic indices in detecting contraction changes assessed by echocardiography in young healthy humans. Eur J Echocardiogr. 2011 Dec;12(12):924-30. Epub 2011 Sep 22.
A full-length cowl, an annular exhaust system and a bucket thrust-reverser were fitted for the Convair 990. The unique feature of the -23 was the transonic single stage fan. NACA had done a lot of research on multistage transonic compressors during the 50s. Using this data, GE decided to design and test a high-pressure ratio single stage transonic fan.
The motors drive the sun and annular gears, while the output is taken from the planet gear carrier. This gives 3 different speeds depending on which motors are on. Chinese south-pointing chariots may also have been very early applications of differentials. The chariot had a pointer which constantly pointed to the south, no matter how the chariot turned as it travelled.
The HMU regulates the amount of fuel delivered to the engine by means of an electrohydraulic servo valve that, in turn, drives a fuel metering valve, that provides information to the full authority digital engine controller (FADEC).Croft, John. "Fueling fears", Aviation Week and Space Technology, 18 February 2013, p. 33. In 1989, CFMI began work on a new, double-annular combustor.
The lateral rectus originates at the lateral part of the annulus of Zinn, also known as the annular tendon or common tendinous ring, and inserts into the temporal side of the eyeball. The annulus of Zinn is a tendinous ring that surrounds the optic nerve and serves as the origin for five of the six extraocular muscles, excluding the inferior oblique muscle.
The IIG included the Astafan's characteristic variable-pitch fan, installed in front of an Astazou XVI core (comprising two axial compressor stages preceding a centrifugal compressor on a common shaft). The design also included an annular reverse-flow combustor and a three-stage turbine section. The resulting configuration yielded a bypass ratio of 8.8 and a pressure ratio of 9.1.
This is a list of solar eclipses in the 20th century. During the period 1901 to 2000 there were 228 solar eclipses of which 78 were partial, 73 were annular (two non-central), 71 were total (three non-central) and 6 were hybrids. The greatest number of eclipses in one year was five, in 1935, and one month, July 2000, had two eclipses.
The boiler was a replacement for the original, fitted in 1922, but is similar to the original. The cylindrical boiler measures by , with two Morrison furnaces connecting to a combustion chamber at the rear. The fire tubes pass from the back to the front of the boiler. Exhaust passes through an annular steam dryer/superheater on its way to the smokestack.
The tentacles are short, globular, and closer to the eye than the nostril. There are 124–133 primary annuli. The body has mostly brownish dorsal ground colour, becoming more grey/lavender posteriorly and paler laterally and ventrally. Granular glands appear as white flecks scattered over much of the body; their alignment with the annular grooves makes the grooves conspicuous, more so posteriorly.
In 1929, it became possible for the first time to produce metal bellows. These were also developed by Albert Dreyer of Lucerne, but independently of Witzenmann. Metal bellows are created by rolling annular corrugations into a smooth extruded or welded pipe. In 1946, Albert Dreyer developed a multi-walled joint that was designed to accommodate axial movements as well: the axial expansion joint.
The F118 is a non-afterburning derivative of the F110 specially developed for the B-2 Spirit stealth bomber. A single stage HP turbine drives the 9 stage HP compressor, while a 2-stage LP turbine drives the 3 stage fan. The combustor is annular. In 1998, the USAF's Lockheed U-2S fleet was fitted with a modified version of the F118.
A single-stage turbine drives the 10 stage all-axial compressor, whilst a two-stage free power turbine drives the load. The combustor is annular. The Gnome differed from the T-58 in having a British developed fuel control system (Lucas). Because an all-axial design is employed, the final stage compressor rotor blades are amongst the smallest ever manufactured.
The powerplants selected were the same type of Daimler-Benz DB 603A Kraftei "power-egg" unitized engine installations, complete with their He 219-style annular radiators that were placed on the wings of the quartet of ordered He 177B prototypes, but for the He 274's use, added DVL-designed TK 11 turbochargers, one per engine, for better power output at high altitude.
CDH1, CHEK2, PALB2 and RAD50 have also been associated with ovarian cancer. Several rare genetic disorders are associated with specific subtypes of ovarian cancer. Peutz–Jeghers syndrome, a rare genetic disorder, also predisposes people to sex cord tumour with annular tubules. Ollier disease and Maffucci syndrome are associated with granulosa cell tumors in children and may also be associated with Sertoli-Leydig tumors.
The lamellae are adnate, and light brown to dark purple brown in maturity, with lighter gill edges. There is no distinct annulus, but immature P. cyanescens specimens do have a cobwebby veil which may leave an annular zone in maturity. Both the odor and taste are farinaceous. P. cyanescens has smooth, elliptical spores which measure 9 - 12 x 5 - 8 µm.
The intuitive scenario is that the induced currents surrounding each magnetic line counteract each other, so that a net induced current is concentrated only near the periphery of plasma. It means the hottest part of plasma is off-axis. Therefore, the induction plasma is something like an "annular shell". Observing on the axis of plasma, it looks like a bright "bagel".
Both forms were worn at the shoulders. The brooch was popular from the sixth to seventh centuries, although worn as late as the eighth century. It has a geographical distribution similar to the annular brooch: throughout southern England, the midlands, east anglia and north east England. After the seventh century, the pennannular brooches were made in Celtic, Irish and Viking art styles.
In general, well completions may not incorporate a packer when the annular space is used as a production conduit. A production packer is designed to grip and seal against the casing ID. Gripping is accomplished with metal wedges called "slips." These components have sharpened, carburized teeth that dig into the metal of the casing. Sealing is accomplished with large, cylindrical rubber elements.
Historic saros cycle animation January 26, 2009 Partially of an annular event from Riversdale, South Africa Series member 50 Saros cycle series 131 for solar eclipses occurs at the Moon's ascending node, repeating every 18 years, 11 days, containing 70 events. All eclipses in this series occurs at the Moon's ascending node. This solar saros is linked to Lunar Saros 124.
There is a Coudé focus provided for there interferometric array. The comparatively small secondary mirror is 2.74 m in diameter, which will serve active corrections. Other characteristics include: #Partial annular submirrors #One of coude planar mirrors is aspherical; better image quality is obtained from such a system. #A pair of lens-prisms are used in a wide field of view system.
Partial solar eclipse of May 31, 2003 (of annular event) from Florenville, Belgium, member 22 of Saros series 147 Saros cycle series 147 for solar eclipses occurs at the Moon's ascending node, repeating every 18 years, 11 days, containing 80 events. All eclipses in this series occurs at the Moon's ascending node. This solar saros is linked to Lunar Saros 140.
Satellite image of the eclipse over East Africa. Red dots show where fires were burning in vegetated areas. An annular solar eclipse occurred on October 3, 2005 with a magnitude of 0.958. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth.
Following an improved and intense convective core structure with cooler cloud tops surrounding a large 38-nm wide eye. Dujuan started to undergo explosive intensification. On September 27, Dujuan rapidly reached peak intensity based on JTWC data, with winds of 240 km/h (150 mph). The typhoon became more symmetric, taking on annular characteristics, while featuring a large and well-defined eye.
The scleral spur is an annular structure composed of collagen in the human eye, a protrusion of the sclera into the anterior chamber. It is the origin of the longitudinal and circular fibres (which swerve acutely from the spur to run circumferentially as a sphincter near the periphery of the lens) of the ciliary muscle and is attached anteriorly to the trabecular meshwork.
It looks like a cyclonic storm, similar to a hurricane, but it does not rotate. The cloud appears during the northern summer and at high latitude. Speculation is that this is due to unique climate conditions near the northern pole. Cyclone-like storms were first detected during the Viking orbital mapping program, but the northern annular cloud is nearly three times larger.
Leaves of circular shape (7 cm in diameter) and have a winged venation and a leaf margin. The blade is covered by a dark annular area, more or less visible depending on the variety. The zoned geraniums are very floriferous plants, not quite demanding when it comes to water. Flowering occurs without interruption from spring until the last days of autumn.
Annales de dermatologie et de syphilographie, Paris, 1916-1917, 5: 57-58. Many different terms have been used to classify these types of lesions and it is still controversial on what exactly defines EAC. Some of the types include annular erythema (deep and superficial), erythema perstans, erythema gyratum perstans, erythema gyratum repens, darier erythema (deep gyrate erythema) and erythema figuratum perstans.
Tinea corporis (also known as "ringworm", tinea circinata, and tinea glabrosa) is a superficial fungal infection (dermatophytosis) of the arms and legs, especially on glabrous skin; however, it may occur on any part of the body, it present as annular, marginated plaque with thin scale and clear center. Common organism are Trichophyton mentagrophytes and Micosporum canis. Treatment include : Grisofluvine, itraconazole and clotrimazole cream .
The castle can be made from individual bricks; usually with interlocking chevron edges to prevent "shine paths" of direct radiation through the gaps. They can also be made from lead produced in bespoke shapes by machining or casting. Such an example would be the annular ring castle commonly used for shielding scintillation counters. A typical lead brick weighs about ten kilograms.
Koreozospeum has a thin, squat ovate-conic shell, which shows fine spiral rows of interconnected pits constant throughout the teleoconch. The peristome has an oblique, ear-shaped (auriform) form. The shell shows a conspicuously pleated lip folded back onto the body whorl. Koreozospeum has an interrupted lamellar ridge on the next to last whorl, which then develops a uniformly shaped annular lamella.
The sporangia, which were about in diameter, had spines like the stems, and split (dehisced) along their margin to release the trilete spores, which were in diameter. Vascular tissue was present in the stems, with tracheids having annular, spiral thickenings., p. 254 D. longistipa somewhat resembles Sawdonia, but differs in branching pattern and in the arrangement of the sporangia, including their long stalks.
Ainhum is an acquired and progressive condition, and thus differs from congenital annular constrictions. Ainhum has been much confused with similar constrictions caused by other diseases such as leprosy, diabetic gangrene, syringomyelia, scleroderma or Vohwinkel syndrome. In this case, it is called pseudo-ainhum, treatable with minor surgery or intralesional corticosteroids, as with ainhum.James, William; Berger, Timothy; Elston, Dirk (2005).
Majocchi's disease, also known as Purpura annularis telangiectodes of Majocchi is a not-well-recognized and uncommon skin condition characterized by purple/bluish-red 1- to 3-cm annular patches composed of dark red telangiectases with petechiae. It is one of a group of disorders referred to as pigmented purpuric dermatosis that all occur as a result of vascular inflammation and pigment deposition.
However, there are primary causes of mitral stenosis that emanate from a cleft mitral valve. It is the most common valvular heart disease in pregnancy. Other causes include infective endocarditis where the vegetations may favor increase risk of stenosis. Other rare causes include mitral annular calcification, endomyocardial fibroelastosis, malignant carcinoid syndrome, systemic lupus erythematosus, whipple disease, fabry disease, and rheumatoid arthritis.
The Richat Structure is the location of exceptional accumulations of Acheulean artifacts. These Acheulean archaeological sites are located along wadis that occupy outermost annular depression of this structure. Pre-Acheulean stone tools also have been found in the same areas. These sites are associated with rubbly, chaotic outcrops of quartzite that provided the raw material needed for the manufacture of these artifacts.
This discrepancy in stone count may be attributed to some researchers including or omitting a stone slab inside the top of the tower and not visible from the outside. The stones are fashioned as annular sectors, meaning each stone takes the shape of a curved or bent rectangle. Its construction style parallels that used at the Bunhwangsa Temple in Gyeongju.
It looks like a cyclonic storm, similar to hurricane, but it does not rotate. The cloud appears during the northern summer and at high latitude. Speculation is that this is due to unique climate conditions near the northern pole. Cyclone-like storms were first detected during the Viking orbital mapping program, but the northern annular cloud is nearly three times larger.
The craft contained a cigar-shaped fuselage with low-mounted wings. Unusually, it contained two engines mounted in the junction of the wing and the fuselage, as opposed to on the wings, to allow it to continue running if one engine failed. This also would allow a sleeker and more aerodynamic design. Two annular radiators were present on front of the propellers.
The same successive milling steps applied when making TEM samples can be applied to make conical samples for atom probe tomography. In this case the ion moved in an annular milling pattern with the inner milling circle being made progressively smaller. The beam current is generally reduced the smaller the inner circle becomes to avoid damaging or destroying the sample.
Soemmering ring is an annular swelling of the periphery of the lens capsule. In 1928, Samuel Sömmerring observed posterior capsule opacification and then described Soemmering's ring as deposits of retained equatorial lens epithelial cells which continue to proliferate and form new cortical fibers which eventually form a ring of cortical fibers between the posterior capsule and the edges of the anterior capsule remnant.
He correctly connected the appearance of secondary flow (in both Earth atmosphere and tea cup) with ″friction on the bottom″.James Thomson, On the grand currents of atmospheric circulation (1857). Collected Papers in Physics and Engineering, Cambridge Univ., 1912, 144-148 djvu file The formation of secondary flows in an annular channel was theoretically treated by Boussinesq as early as in 1868.
The internal layout varies from one autoclave to another. Some have an air duct at the six-o'clock position which also carries the cart rails, while others have a wide floor with the mechanical components beneath it. Others have the air duct at the top. Typically, autoclaves use an annular air duct running across the full circumference of the interior.
Hindwing: uniform, with a very small annular spot on the discocellulars. Cilia white. Antennae, head, thorax and abdomen black, the antennae speckled and tipped with white, the thorax clothed with long bluish-grey hairs; beneath: palpi, thorax and abdomen white. The female upperside is very similar to that of the male, with her terminal bands broader and brownish rather than black.
Animated path It was the last solar eclipse of 2019. The central path of the 2019 annular eclipse passed through Saudi Arabian Peninsula, southern India, Sumatra, Borneo, Philippines and Guam. A partial eclipse was visible thousands of kilometers wide from the central path. It covered small parts of Eastern Europe, much of Asia, North/West Australia, East in Africa, Pacific and Indian Ocean.
As part of the Emergency Fighter Program (), at the beginning of 1945, a programme was launched by the OKL for a new generation of fighter/interceptor aircraft in order to replace the He 162 Volksjäger. The new aircraft was intended to have superior performance, in order to deal with high-altitude threats such as the B-29 Superfortress. Messerschmitt designed a number of different high-altitude fighter projects which were submitted in February 1945. One of the designs, the Me P.1110 Ente (Duck), had a 40° wing sweep and annular air intakes in front of the wing root (similar to those on the post-war North American YF-93), feeding a single Heinkel HeS 011A jet engine; the annular intakes, while flowing four percent less air, would produce fifteen percent less drag than a single nose intake.
Female in Hyderabad, India Underside, forewing: white, suffused with sulphur yellow at base of cell and with ochraceous (in some specimens ochraceous grey, in others ochraceous red) on apical area; spot on discocellulars, the postdiscal macular band and spots in interspaces 1 and 2 as on the upperside, but more clearly defined, the spots that compose the postdiscal band sometimes annular. Hindwing: white, suffused to a greater or less degree with, ochraceous, sometimes pink; spot on discocellulars and discal macular band as on the upperside, but both the discocellular spot and the spots that compose the latter more clearly defined, annular and generally centred with carmine; a terminal row of black specks which may or may not be connected by a very slender anteciliary line. Wingspan of 45–50 mm in males and 48–52 mm in females.
Tests showed that the heat was so oppressive that all instruments were baked brown after only a few flights. A completely new design was installed over the winter. The original spoilers were removed and replaced by a single ring below the annular flap. The ring shifted in relation to the craft under control input, "sealing off" the gap on one side while opening it on the other.
In case of infants, research has shown that only in 15% of the cases A1 pulley release alone is sufficient. In most of the cases there was an additional annular pulley structure distal to the A1 to be released resolving the triggering: the so-called Av pulley or variable pulley. Therefore, infants and adults need to be treated differently as the main problem is different.
One study suggests that the most cost-effective treatment is two trials of corticosteroid injection, followed by open release of the first annular pulley. Choosing surgery immediately is the most expensive option and is often not necessary for resolution of symptoms. A 2009 Cochrane review of corticosteroid injection for trigger finger found only two pseudo-randomized controlled trials for a total pooled success rate of only 37%.
In contrast, nodes found in the sheaths of invertebrates are either annular or fenestrated; i.e. they are restricted to "spots". It is notable that the fastest recorded conduction speed (across both vertebrates and invertebrates) is found in the ensheathed axons of the Kuruma shrimp, an invertebrate, ranging between 90 and 200 m/s (cf. 100–120 m/s for the fastest myelinated vertebrate axon).
The medial portion is the larger, and is slightly concave transversely; the lateral is convex above, slightly concave below. The radial notch is a narrow, oblong, articular depression on the lateral side of the coronoid process; it receives the circumferential articular surface of the head of the radius. It is concave from before backward, and its prominent extremities serve for the attachment of the annular ligament.
The antumbra (from Latin ante, "before") is the region from which the occluding body appears entirely within the disc of the light source. An observer in this region experiences an annular eclipse, in which a bright ring is visible around the eclipsing body. If the observer moves closer to the light source, the apparent size of the occluding body increases until it causes a full umbra.
Pandanus utilis is a palm-like evergreen tree, ranging in height up to . They are found in tropical areas and have an upright trunk that is smooth with many horizontal spreading branches with annular leaf scars. Old leaf scars spiral around the branches and trunk, like a screw. The anatomy of Pandanaceae stems can be distinguished from other monocotyledons by the presence of a compound vascular bundle.
A rubber bushing may also be described as a flexible mounting or antivibration mounting. These bushings often take the form of an annular cylinder of flexible material inside a metallic casing or outer tube. They might also feature an internal crush tube which protects the bushing from being crushed by the fixings which hold it onto a threaded spigot. Many different types of bushing designs exist.
The terminal antennomere is highly acute and narrow, approximately 0.33 the width of the pedicel and 0.25 the width of the scape. The scape is annular and much wider than it is long. It is the shortest segment. The pedicel is longer than scape, bearing conical sensorium on the distal surface near the outer rim, and a pair of pre-apical setae on the outer rim.
The hydrogen pressure inside the casing is maintained slightly higher than atmospheric pressure to avoid outside air ingress. The hydrogen must be sealed against outward leakage where the shaft emerges from the casing. Mechanical seals around the shaft are installed with a very small annular gap to avoid rubbing between the shaft and the seals. Seal oil is used to prevent the hydrogen gas leakage to atmosphere.
This list of solar eclipses seen from China describes precise visibility information for solar eclipses and major cities in China. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring Earth's view of the Sun. Eclipses can be total, annular, or partial. The zone of a total eclipse where the sky appears dark is often just a few miles wide.
Lord Kan II used the dates of important astronomical phenomena for these.Schele & Freidel (1990)p. 210, fig 5.4 For example: 9.5.19.1.2 9 Ik 5 Uo – April 14, 553, total lunar eclipse – Accession of Lord Water, grandfather of Kan II 9.6.8.4.2 7 Ik 0 Zip – April 27, 562, annular solar eclipse 8 days ago and penumbral lunar eclipse in 7 days – Star war to Tikal 9.7.19.10.
In humans and most mammals and birds, the iris (plural: irides or irises) is a thin, annular structure in the eye, responsible for controlling the diameter and size of the pupil and thus the amount of light reaching the retina. Eye color is defined by that of the iris. In optical terms, the pupil is the eye's aperture, while the iris is the diaphragm.
A rotating detonation engine (RDE) is a proposed engine using a form of pressure gain combustion, where one or more detonations continuously travel around an annular channel. Computational simulations and experimental results have shown that the RDE has potential in transport and other applications. In detonative combustion, the results expand at supersonic speed. It is theoretically more efficient than conventional deflagrative combustion by as much as 25%.
His final prototype confirmed the inefficiency and poor performance of the idea. Other radical approaches to wing design were also being tried. The Scottish-born inventor Alexander Graham Bell devised a cellular octahedral wing form which, like the multiplane, proved disappointingly inefficient. Other lacklustre performers included the Edwards Rhomboidal, the Lee-Richards annular wing and varying numbers of wings one after the other in tandem.
Saros 121 February 7, 2008 event from New Zealand Partiality from annular event Series member 60 Saros cycle series 121 for solar eclipses occurs at the Moon's ascending node, repeating every 18 years, 11 days, contains 71 solar eclipse events. 55 of these are umbral eclipses. All eclipses in this series occurs at the Moon's ascending node. This solar saros is linked to Lunar Saros 114.
The adult Mexican burrowing caecilian grows to a length of . In general appearance, it resembles a large earthworm. Around a hundred transverse annular folds in the skin give the appearance of segments. The head has a pointed snout, a single row of teeth in the lower jaw, and two vestigial eyes covered with skin, with a pair of protrusible tentacles between the eyes and the nostrils.
The motion thus induced is controllable by the angle at which an annular ring enclosure is pressed against the Flaw. The same spatial transform also can be used to turn tip turbines in order to generate electricity. The Flaw permits a violation of the First Law of Thermodynamics, therefore defining the Way as a perpetual motion machine of the First Order, making energy out of nothing.
The hotel offers views of The Bund, a stretch of restored historical buildings, along the Huangpu River. 18 different room styles are offered. The Hyatt's barrel-vaulted atrium starts at the 56th floor and extends upwards to the 87th. Lined with 28 annular corridors and staircases arrayed in a spiral, it is 27 m in diameter with a clear height of approximately 115 m.
Hellebore, in particular, is known to be abortifacient. Tertullian, a 2nd- and 3rd-century Christian theologian, described surgical implements which were used in a procedure similar to the modern dilation and evacuation. One tool had a "nicely adjusted flexible frame" used for dilation, an "annular blade" used to curette, and a "blunted or covered hook" used for extraction. The other was a "copper needle or spike".
Annular mist flow occurs at high gas velocities. A thin film of liquid is present around the annulus of the pipe. Typically most of the liquid is entrained in the form of droplets in the gas core. As a result of gravity, there is usually a thicker film of liquid on the bottom of the pipe as opposed to the top of the pipe.

The genus name Polistes is most likely derived from the Greek polistes (πολιστης) which is translated as “founder of a city”. The specific epithet comes from the Latin word ānnulāris, an alternate spelling of ānulāris. The root word ānnulus is a noun, meaning 'ring', and -ālis is a suffix that modifies a noun into an adjective. Together, the word ānulāris means "ringed", "ring-shaped", or "annular".
Increase in the number of 3D structures of membrane proteins known Membrane protein structures can be determined by X-ray crystallography, electron microscopy or NMR spectroscopy. The most common tertiary structures of these proteins are transmembrane helix bundle and beta barrel. The portion of the membrane proteins that are attached to the lipid bilayer (see annular lipid shell) consist mostly of hydrophobic amino acids.White, Stephen.
Another is the flow within cyclone separators; the swirling flow there occurs in an annular region between two tubes. The flow reverses at the closed end of the outer tube and exits through the inner tube. Under certain conditions, the flow in the reversal region becomes unstable, resulting in a period rotating force on the outer tube. Periodic vibration of a cyclone separator would indicate vortex instability.
3 of Fundamentals of Naval Weapons Systems The Mobin employs the "Toloo-4" turbojet engine. The engine is a single shaft turbojet engine which consists of 3 stage axial compressor, direct annular combustion chamber and 1 stage axial turbine. It weighs 55.9 kg with a diameter of 330mm and length of 1130mm-1330mm. The engine thrust is rated at 345daN with an engine speed of 28500RPM.
The Luckenbooth brooch is a style of brooch that originated on the Royal Mile in Edinburgh. It is a kind of annular brooch that is heart shaped. It often comes in the form of two hearts woven together, with more ornate brooches also containing a crown pattern. The name Luckenbooth comes from the locked booths along the royal mile that had a similar pattern.
X-ray of ventral dislocation of the radial head. There is calcification of annular ligament, which can be seen as early as 2 weeks after injury. Elbow dislocations constitute 10% to 25% of all injuries to the elbow. The elbow is one of the most commonly dislocated joints in the body, with an average annual incidence of acute dislocation of 6 per 100,000 persons.
Annularity was visible in Mexico, the United States, Azores Islands, Morocco and Algeria. It was the first annular solar eclipse visible in the US in 33 years. The moon's apparent diameter was near the average diameter because occurs 6.7 days after apogee (Apogee on May 24, 1984 at 01:00 UTC) and 7.8 days before perigee (Perigee on June 7, 1984 at 11:15 UTC).

While this presented additional surface to the blast, the annular orifice had a tendency to become clogged, which increased back pressure, and the exhaust pipes therefore frequently had to be taken out for cleaning. As delivered, the locomotive had thick wooden buffer beams which were later replaced by thick steel plates. The distance between the locomotive's tyres, i.e. between the wheel flanges on the axle, was .
There were two other eclipses that year. The first was a partial lunar eclipse, during which the shadow of the earth can be seen on the moon, and another solar eclipse that took place on December 3 over South America. The other solar eclipse, however, was an annular eclipse, which occurs when the moon has a smaller apparent diameter and therefore never fully obscures the sun.
At that time, the cyclone was also beginning to acquire some annular characteristics. The hurricane's structure began to decay on August 5, with the eye becoming less distinct by 12:00 UTC. Meanwhile, microwave imagery showed two concentric eyewalls, indicating that Hector was entering a second eyewall replacement cycle. Hector became a Category 4 hurricane at 18:00 UTC after completing the eyewall cycle.
For example, in mining process currently in Mozambique, annular fluidised beds are used to preheat and reduce ilmenite ore, ilmenite is hazardous compound as crystalline silica is known to cause lung fibrosis and is a known carcinogen.Doral Mineral Sands Pty. Ltd. 2007, Material safety Data sheet ilmenite, viewed on 12 October 2013 <> Companies operating such equipment and detrimental substances must dispose of their waste properly.
When steam passes from one stage to another through the diaphragm, some energy losses takes place, which are referred to as carry over losses and therefore, the kinetic energy of steam available at succeeding stage of moving blades for utilization is less than that of the exit at preceding stage. This is due to formation of eddies in annular space between the nozzle and moving blades.
Subacute cutaneous lupus erythematosus is a clinically distinct subset of cases of lupus erythematosus that is most often present in white women aged 15 to 40, consisting of skin lesions that are scaly and evolve as poly-cyclic annular lesions or plaques similar to those of plaque psoriasis.James, William; Berger, Timothy; Elston, Dirk (2005). Andrews' Diseases of the Skin: Clinical Dermatology. (10th ed.). Saunders.
This was done by replacing the multiple individual chambers with a single annular casing with individual flame tubes or cans known as cannular. The pressure ratio was increased and variable inlet guide vanes fitted to prevent low-RPM problems (rotating stall/blade flutter) with the higher design pressure ratio. A 2-stage turbine was required. A low boost (10% at take-off) afterburner was fitted.
Hurricane Daniel was the second strongest hurricane of the 2006 Pacific hurricane season. The fourth named storm of the season, Daniel originated on July 16 from a tropical wave off the coast of Mexico. It tracked westward, intensifying steadily to reach peak winds of 150 mph (240 km/h) on July 22. At the time, the characteristics of the cyclone resembled those of an annular hurricane.
Sometimes the pancreas fails to develop normally and there may be congenital defects associated with the uncinate process. The uncinate process may split and encircle the duodenum, which is known as an annular pancreas.Drake et al, Gray's Anatomy for Students, Churchill Livingstone/Elsevier (2010), 2nd edition, chapter 4 There is also a common condition called pancreas divisum where the dorsal and ventral pancreas do not fuse properly.
It is a tubular annular torc, which would have had a hinge and catch. It is of ornate design compared to the ribbon torcs, and experts have identified it as a type originating from the Toulouse area in southern France. It is the first of its kind to have been found in Britain.MOS The fourth torc is a looped terminal torc, complete and in good condition.
Underside similar to that of the male, but the ground colour very much paler and more ochraceous than green. In some specimens, in addition to the black spots in interspaces 1 and 2 on forewing, there is an anterior postdiscal fuscous curved band. Hindwing: discocellular spot larger than in the 3 and annular; a curved discal series of reddish spots from costa to dorsum. Form 2.
Metacoceras is a nautilitoid cephalopod from the Upper Carboniferous (Pennsylvanian) and Permian, the shell of which is moderately evolute with a subquadrate whorl section, bearing nodes on the ventral or umbilical shoulders or both, but otherwise smooth. The siphuncle is small, subcentral and orthochoanitic. The suture has shallow ventral and lateral lobes but no dorsal or annular lobe. Matacoceras, named by Hyatt, 1883, is a genus in the nautilid superfamily Tainocerataceae.
A key reference point was the accession of King Yi of Zhou, when according to the "old text" Bamboo Annals the day dawned twice. The Project adopted (without acknowledgement) the proposal of the Korean scholar Pang Sunjoo (方善柱) that this referred to an annular solar eclipse at dawn that occurred in 899 BC. Other scholars have challenged both this interpretation of the text and the astronomical calculations involved.
Crushed stone is introduced into the hole by one of two methods. In the dry bottom method, a pipe attached to the vibrator supplies stone directly to it. In the wet top method, water jets located in the vibrator's tip create an annular space around the vibrator through which stone is introduced from the top. The vibrating probe breaks down the pores of the surrounding soil, thereby densifying the soil.
The suit had a positive buoyancy of . Ballast was attached to the suit's front and could be jettisoned from within, allowing the operator to ascend to the surface at approximately per minute. The suit also incorporated a communication link and a jettisonable umbilical connection. The original JIM suit had eight annular oil-supported universal joints, one in each shoulder and lower arm, and one at each hip and knee.
In order to minimise the diameter the widest part of the annular combustor was placed in line with the smaller diameter axial entry to the impeller. At exit from the impeller the air flowed forwards, then turned through 180 degrees to flow rearward through the combustor. The flow was then turned radially inwards to enter the turbine. Although not as compact as the original design, the 3b was much simpler.
The beryllium is surrounded by a water reflector of effectively infinite thickness. In the axial direction, the reactor is reflected by water. The control plates, in the form of two thin, nuclear poison-bearing concentric cylinders, are located in an annular region between the outer fuel element and the beryllium reflector. These plates are driven in opposite directions to open and close a window at the core mid-plane.
A small annular eclipse covered only 93% of the Sun in a very broad path, 953 km wide at maximum, and lasted 6 minutes and 3 seconds. This was the second solar eclipse in 1979, the first one a total solar eclipse on February 26. This was the last of 40 umbral eclipses of Solar Saros 125. The first was in 1276 and the last was in 1979.
Actinic granuloma is a cutaneous condition characterized histologically by a dermal infiltrate of macrophages. Actinic granuloma is an asymptomatic granulomatous reaction that affects sun-exposed skin, most commonly on the face, neck, and scalp. It is characterized by annular or polycyclic lesions that slowly expand centrifugally and have an erythematous elevated edge and a hypopigmented, atrophic center. Advise to reduce exposure to the sun and to use sunscreen.
Truck-mounted core drill A core drill is a drill specifically designed to remove a cylinder of material, much like a hole saw. The material left inside the drill bit is referred to as the core. Core drills used in metal are called annular cutters. Core drills used for concrete and hard rock generally use industrial diamond grit as the abrasive material and may be electrical, pneumatic or hydraulic powered.
The hairy fruit enclosed by the bracteoles is ovate and compressed, its membranous pericarp is free from the seed. The vertically orientated seed has a brown thin seed coat covered with white hairs. The embryo is nearly annular or horseshoe-shaped and encloses the copious perisperm. The chromosome base number is x=9, for example 2n=36 for Krascheninnikovia ceratoides, 2n=18 and 2n=36 for Krascheninnikovia lanata.
Another attempt to solve the overheating problems resulted in the more highly modified F.2/3 during 1943. This version replaced the original annular combustion chamber with can-type burners like those on the Whittle designs. This appears to have solved the problems, raising the thrust to in the process. However, by this time it was decided to move on to a much more powerful version of the engine.
The Ardiden 1 offers and the Ardiden 3 covers the range, for single and twin-engine helicopters. The Ardiden has a two-stage centrifugal compressor, then a reverse flow annular combustor, a single stage axial gas generator turbine followed by a two-stage axial free turbine outputting its power to the front by a concentric shaft, and is controlled by a dual-channel digital engine electronic control unit.
Above the tube banks a single flat spiral tube was used as an economiser or feedwater heater. The furnace used to fire these large boilers was annular, often with four or more separate firedoors. The boiler was also successfully fired with bagasse, plant waste or refuse. Where they were used for continual high-power production, such as for electricity generation, some were also used with early automatic stokers.
January 15, 2010 Annularity from Bangui, Central African Republic Series member 23 Saros cycle series 141 for solar eclipses occurs at the Moon's ascending node, repeats every 18 years, 11 days and contains 70 events. The series started with a partial solar eclipse on May 19, 1613. It contains 41 annular eclipses from August 4, 1739 through October 14, 2460. There are no total eclipses in this series.
It is thought that annular gap junctions result from engulfment by one of the two cells of the membrane plaque to form a vesicle within the cell. This example shows three layers to the junction structure. The membrane from each cell is the dark line with the whiter narrow gap between the two darkly stained membranes. In such electron micrographs there may appear to be up to 7 layers.
The path of annularity will cross North America and South America. This will be the 47th solar eclipse of Saros cycle 134. A small annular eclipse will cover only 94% of the Sun in a very broad path, 262 km wide at maximum, and will last 7 minutes and 54 seconds. Occurring only 4 days after apogee (Apogee on Thursday, November 11, 2077), the Moon's apparent diameter is smaller.
Later that day, Jasmine reached its peak intensity as it passed 280 km (175 mi) to the northeast of New Caledonia, with wind speeds of 215 km/h (135 mph), equivalent to a Category 4 cyclone on both the Australian and Saffir- Simpson hurricane scales (SSHS). Throughout 8 February, Jasmine began to show characteristics of an annular hurricane, maintaining a large, asymmetric eye and rather shallow convective features.
The wide system displayed annular characteristics and a wide eye. Pat reached its peak strength early on February 10 as a severe tropical cyclone with winds of 140 km/h (85 mph) and a barometric pressure of 960 mbar (hPa; 28.35 inHg). Hours later it struck Aitutaki, producing gusts in excess of 185 km/h (115 mph) on the island. Hostile wind shear then prompted rapid weakening of the cyclone.
As an alternative to Blish's idea of launching existing cities into space, Niven proposes a giant annular spaceship, which rotates to generate artificial gravity. ; Inside Outside This describes a hollowed-out planetoid, with living quarters inside. ; Macro-Life Any of the foregoing could be made self-sufficient and a permanent habitation, enlarged by materials obtained from planetary systems. ; Worlds Niven introduces the concept of engineering and terraforming whole planets.
The E. ypsipeda forewings are distinct from E. elverumi in that they all have Sc4 and Sc5 forks on the Sc vein. There are no cross veins connecting either the Rs3 and Rs4 or the M3 and M4. The wings all have a notable patterning to the coloration and range from in length. The head and body have the general panorpiod body morphology, though the legs show fine annular hair growths.
On May 3 an area of disturbed area formed south east of the Mariana Islands. A day later the system strengthened into a tropical depression, and continued to intensify into typhoon status four days later. The system showed annular characteristics on May 11, showing an axisymmetric shape. Walt reached peak intensity on May 12, before showing a distinct eyewall replacement cycle lasting four hours from late May 13 to May 14.
The central orifice is in the form of an Allen socket on the face which accepts the Yoke fitting. Both ends have face sealing O-ring grooves. alt= A yoke adaptor shows the DIN socket at one end. The opposite end of the socket piece has the annular ridge for sealing against the O-ring of the cylinder valve, and the yoke with co-axial clamping screw at the far end.

This is called an annular eclipse, from Latin annulus, meaning "ring". For a total solar eclipse to happen, the ratio of the apparent diameters of the Moon and of the Sun must be 1.0 or more, and the three celestial bodies (Sun, Earth and Moon) must be aligned centrally enough. When that is the case, the Moon's disk covers the Sun's disk in the sky completely. The path of totality (i.e.
A key advantage of a well cluster over a nested well is that there is less potential for vertical leakage and hydraulic short-circuiting because reliable annular seals are installed in each separate borehole in the cluster. However, well clusters require drilling multiple boreholes, which results in higher construction costs compared to nested wells. Economical alternatives to well clusters are multilevel groundwater monitoring systems, also referred to as engineered nested wells.
Kraft Foods and Swizzels Matlow (owner of British Navy Sweets) have made similar applications for annular sweets bearing the mark LIFESAVERS or NAVY. Nestlé has tried to oppose these trademark applications but has failed as the court ruled that customers would be able to distinguish between a Polo, a Lifesaver and a British Navy mint as all of them have their marks boldly and prominently embossed on the mint.
The term "tinea pseudoimbricata" synonymuos with "tinea indecisiva", was coined to describe a form of tinea mimicking the concentric rings of tinea imbricata, but is caused by local or systemic immunosuppression. Since then, 3 cases of Trichophyton tonsurans have been associated with it,Ouchi T1, Nagao K, Hata Y, Otuka T, Inazumi T. Trichophyton tonsurans infection manifesting as multiple concentric annular erythemas. J Dermatol. 2005 Jul;32(7):565-8.
A swan neck duct is a jet engine component, usually situated within the compression or turbine expansion system. Many jet engines have a short annular passageway, linking two components, where there is a large change in mean radius, from front to rear. The shape of the resulting passageway is often similar to that of a swan or goose neck. Consequently, such a passageway is called a swan (or goose) neck duct.
Model tests of a new design at the National Physics Laboratory gave promising results, suggesting that an annular monoplane would be aerodynamically stable and have benign stalling characteristics. The first full-size monoplane was taken for its maiden flight in 1913 by Gordon England. It was found to be stable in the air but was tail-heavy and crashed when the engine failed. England survived to fly the next one.
The huge annular piston valves can deliver up to of water. It is currently being investigated whether the water outflow can be used for energy purposes. The bedrock consists of manganese slate that is not particularly watertight. So that the dam wall is not lifted up from underneath by water pressure at the base, the pressure at the foot is relieved by over 40 bubble caps (Glocken) with drainage pipes (Steigleitungen).
Bottom hole pressure is used to represent the sum of all the pressures being exerted at the bottom of the hole. The pressure is imposed on the walls of the hole. The hydrostatic fluid column accounts for most of the pressure, but the pressure to move fluid up the annulus also acts on the walls. In larger diameters, this annular pressure is small, rarely exceeding 200 psi (13.79 bar).
On December 17, 1987 an incident (INES 1) occurred: Operators overlooked a stop valve that had not been closed. In order to close the armature a valve was opened. The radioactive primary cooling water discharged for a short time into the annular space. Because the discharge of the reactor cooling water took place outside of the reactor containment, there was potentially no feedback from the sump over the safety cooling pumps.
The hurricane exhibited a symmetric central dense overcast with few banding features elsewhere, a characteristic of an annular tropical cyclone. Hector began to move slightly north of west due to a weakness in a subtropical ridge located to the northeast of the Hawaiian Islands. The hurricane crossed the 140th meridian west shortly after 06:00 UTC on August 6, entering the Central Pacific Hurricane Center's (CPHC) area of responsibility.
Segmental sliplining is very similar to continuous sliplining. The difference is primarily based on the pipe material used as the new carrier pipe. When using any bell and spigot pipe such as FRP, PVC, HDPE or Spirally Welded Steel Pipe, the individual pieces of pipe are lowered into place, pushed together, and pushed along the existing pipe corridor. Using either method the annular space between the two pipes must be grouted.
A partial lunar eclipse occurred on March 13, 1979, 15 days later, visible over Africa, Europe and Asia. 177 days later after the total solar eclipse of February 26, 1979, occurred an annular solar eclipse on August 22, 1979. A total lunar eclipse followed on September 6, 1979. 355 days after the total solar eclipse of February 26, 1979, occurred a total solar eclipse on February 16, 1980.
The annular duct is attractive by virtue of creating the smallest intrusion into the net available working space inside the autoclave. It reduces the diameter of the cylindrical volume by only several inches. It also creates the greatest skin friction pressure loss. This means that the fan has to be larger for the same amount of air circulation, and that there is more heating from the motor horsepower.
Close-up of a bird in Johannesburg The crowned lapwing is easily recognized by its combination of brown and white colours, with most tellingly, a black crown intersected by an annular white halo. Adults are noisy and conspicuous. Males measure on average 3% larger than females. Juveniles are dull versions of adults, vermiculated on the wings and mantle, the legs yellowy rather than red and the bill lacking the red base.
Along with the spread of Christianity in seventh century England, religious art and European fashion inspired changes in women's dress. These changes were marked by the disappearance of the paired brooch, aside from very small annular and penannular brooches; occasional elaborate, round brooches were also worn individually. Linked pins appeared during the seventh century. There were fewer bead ornaments than before, and amber largely disappeared during this time period.
Sputtering erosion of discharge channel walls and pole pieces that protect the magnetic circuit causes failure of thruster operation. Therefore, annular and cylindrical Hall thrusters have limited lifetime. Although magnetic shielding has been shown to dramatically reduce discharge channel wall erosion, pole piece erosion is still a concern. As an alternative, an unconventional Hall thruster design called external discharge Hall thruster or external discharge plasma thruster (XPT) has been introduced.
The eclipse started with an antumbra having a magnitude of .96; it stretched 164 kilometers wide, and traveled towards the east at an average rate of 1.1 kilometer per second. The longest duration of annularity was 3 minutes and 40 seconds, at 5.30 UT1 occurring in the South China Sea (0°45'54.0"N 105°29'06.0"E).

As the ventricle relaxes, the annulus moves towards the base of the heart, signifying the volume expansion of the ventricle. The peak mitral annular velocity during early filling, e' is a measure of left ventricular diastolic function, and has been shown to be relatively independent of left ventricular filling pressure.Rodriguez L, Garcia M, Ares M, Griffin BP, Nakatani S, Thomas JD.

These engines were equipped with a new two-speed, two-stage supercharger that dramatically improved altitude performance. The only difference between the two models was that the E included an intercooler for additional high-altitude performance, while the F model lacked this and was optimized for slightly lower altitudes. The E and F models were in high demand for many late-war aircraft, including the Junkers Ju 188, Junkers Ju 388, the Langnasen-Dora models of the Focke-Wulf Fw 190D and the Focke-Wulf Ta 152H. All of these aircraft used annular radiators characteristic of the earlier Jumo 211 engine installations on twin-engined aircraft, often standardized as Kraftei (power-egg), completely unitized power plant "modules" for any twin or multi-engined aircraft, much as the Jumo 211 had evolved for earlier aircraft designs – but with the annular radiators noticeably reconfigured for better cooling of the more powerful Jumo 213 engine.
The suit had a positive buoyancy of . Ballast was attached to the suit's front and could be jettisoned from within, allowing the operator to ascend to the surface at approximately 100 feet (30 m) per minute. The suit also incorporated a communication link and a jettisonable umbilical connection. The original JIM suit had eight annular oil-supported universal joints, one in each shoulder and lower arm, and one at each hip and knee.
While the replacement cycle tends to weaken storms as it occurs, the new eyewall can contract fairly quickly after the old eyewall dissipates, allowing the storm to re-strengthen. This may trigger another re-strengthen cycle of eyewall replacement. Eyes can range in size from (Typhoon Carmen) to a mere (Hurricane Wilma) across. While it is uncommon for storms with large eyes to become very intense, it does occur, especially in annular hurricanes.
It gradually curved to the north, and on April 20 JTWC classified Super Typhoon Isa as reaching peak 1-min winds of 270 km/h (165 mph). At this point, Isa became an annular typhoon, with a large eye and a lack of spiralform rainbands, while moving nearly due northward, through a weakness in the subtropical ridge. Simultaneously, JMA assessed the typhoon as attaining peak 10-min winds of 155 km/h (100 mph).
In 1993, Greenough made national news headlines when a woman and her three young children of this small community were murdered. The killing later featured on the Australian television show Crime Investigation Australia. On 16 February 1999, a rare annular solar eclipse of magnitude 0.9906 was visible from the area. In 2006, floodwaters on the Greenough River undermined and caused the collapse of one of the stone pylons of Maley's bridge in Central Greenough.
These had an outer annular orifice for steam and an inner circular opening for exhaust gases and formed the upper portion of a bell-mouth scoop. The lower portion of the scoop was open towards the bottom rows of tubes so that the draught though them was increased. The vortex blast pipes were, however, removed after a few years since it was found to choke up more readily than an ordinary blast pipe.
T 166-21 Awards to Inventors - Macrae and others. Work began the next day. Clarke purchased some large tin bowls from a nearby branch of Woolworth's and a local tinsmith was engaged to make rims with annular grooves and plates which could be screwed on to close the rims. Small horseshoe magnets were fixed in the grooves and with a filling of porridge in place of high explosive, the first prototypes were created.
The duct acts as an annular wing, which evens out the pulsating thrust, by harnessing aerodynamic forces in the pulsejet exhaust. The duct, typically called an augmentor, can significantly increase the thrust of a pulsejet with no additional fuel consumption. Gains of 100% increases in thrust are possible, resulting in a much higher fuel efficiency. However, the larger the augmenter duct, the more drag it produces, and it is only effective within specific speed ranges.
Bochianites is a straight shelled ammonite which lived from the Upper Jurassic, Tithonian, to the Lower Cretaceous, Hauterivian in what is now Europe, Greenland, Africa, North America and Asia.ARKADIEV, V. V.; ROGOV, M. A.; PERMINOV, V. A. New occurrences of heteromorph ammonites in the Berriasian-Valanginian of the Crimean mountains. Paleontological Journal, 2011, 45.4: 390-396. The shell is long, narrow, moderately expanding; smooth or with weak to strong oblique annular ribs.
Manicouagan Reservoir (also Lake Manicouagan) is an annular lake in central Quebec, Canada, covering an area of . The lake island in its centre is known as René-Levasseur Island, and its highest point is Mount Babel. The structure was created 214 (±1) million years ago, in the Late Triassic, by the impact of a meteorite of diameter. The lake and island are clearly seen from space and are sometimes called the "eye of Quebec".
The distal attachment of the annular ligament covering the radial head is weaker in children than in adults, allowing it to be more easily torn. The older child will usually point to the dorsal aspect of the proximal forearm when asked where it hurts. This may mislead one to suspect a buckle fracture of the proximal radius. There is no tear in the soft tissue (probably due to the pliability of young connective tissues).
The haemocoel is divided by a horizontal partition, the diaphragm, into two parts: the pericardial sinus along the back and the perivisceral sinus along the belly. The former encloses the tube-like heart, and the latter, the other organs. The diaphragm is perforated in many places, enabling the exchange of fluids between the two cavities. The heart itself is a tube of annular muscles consisting of epithelial tissues, with two lateral openings (ostia) per segment.
Here, an annular flow of clean gas is introduced around the aerosol stream to focus the droplets into a tightly collimated beam of material. The combined gas streams exit the print head through a converging nozzle that compresses the aerosol stream to a diameter as small as 10 µm. The jet of droplets exits the print head at high velocity (~50 meters/second) and impinges upon the substrate. Electrical interconnects, passive and active componentsJ.
The vz. 52 is a shoulder-fired semi-automatic rifle with a tilting-bolt locking mechanism powered by an annular short-stroke gas piston system. The bolt is locked by two lugs that recess into slots machined into the receiver. However, unlike most vertically-locking breech mechanism, the rifle's bolt has the unusual feature of tipping the bolt frontally to lock the mechanism, whereas other tipping bolt designs tip the bolt to the rear.

Other assignments include the Annular Eclipse on December 14, 2001 broadcast live from Nosara Beach, Guanacaste. Conduction of the Miss Costa Rica 2004 beauty contest alongside Mariamalia Jacobo was praised by the entertainment media. Silva has received many awards in his career as a journalist, such as the "Best Documentary for Central American Television" prize given by Florida International University in 1992. ACAN-EFE has honored him for different special reports in 1992 and 1997.
The recognition of coprolites is aided by their structural patterns, such as spiral or annular markings, by their content, such as undigested food fragments, and by associated fossil remains. The smallest coprolites are often difficult to distinguish from inorganic pellets or from eggs. Most coprolites are composed chiefly of calcium phosphate, along with minor quantities of organic matter. By analyzing coprolites, it is possible to infer the diet of the animal which produced them.
Lake Manicougan in Quebec, Canada A satellite photograph of the Siljan Ring. Lake Siljan is a large part of the southwest edge of the much-eroded crater. Lonar Lake in India An impact crater lake is a lake inside a depression caused by the impact of a meteor. It is also known as an annular lake in cases where the water body is shaped like a ring, as many impact crater lakes are.
The Trent 1000 is a high bypass turbofan with three independent, coaxial shafts and a single annular combustor with 18 spray nozzles. The Low Pressure shaft with a swept-bladed, fan is powered by six axial turbines. The Intermediate Pressure spool with 8 axial compressors is turned by a single turbine stage. The six-stage High Pressure Compressor is driven by a single turbine stage, turning in the opposite direction of the two others shafts.
At a latitude of 5° 24', the sun passes directly overhead at noon time about April 3 and September 8 of each year, causing zero-length shadows. This phenomenon is not possible in high-latitude areas. Astronomers from PAGASA set up on the island to observe the December 26, 2019 Annular Solar Eclipse. Balut Island, Sarangani Island, and Olanivan Island are the only places in the Philippines where the annularity was visible.
With the open ring style, each end contains a hole in which a small pin or bolt is passed to join the ring. These simple brooches are often decorated with stamps or diagonal grooves, but many of this style are undecorated. The flat annular often displays a shiny surface, which is possibly the result of the brooch brushing against clothing. This glossy finish has not been observed on other early Anglo Saxon brooches.
This annular taxonomy organized fragrance families in relation to one another, showing their interchange, a system better suited to retail than the linear, sectional genealogy used in previous editions. It was widely adopted in the industry. Renamed Fragrances of the World in 2000 and published annually, Edwards’ guide has become an authoritative reference in the fragrance industry, colloquially termed the 'Fragrance Bible'. Its online database, updated weekly, archives profiles of over 16,000 fragrances.
Cantilever snap-fit The design of the snap-fit determines what it can be used for. There are three main types of snap-fits: annular, cantilever, and torsional. Most snap-fit joints have a common design of a protruding edge and a snap-in area. The specific name of the snap-fit is usually named after the type of stress or strain it utilizes; the torsional snap-fit uses torque to hold parts in place.
After the collapse, dacitic lava flows in the central sector of the caldera form the first postcollapse volcanism. Reestablishment of the volcanic system was strong enough to form another sequence, thick, of pumice and pyroclastics, possibly the consequence of another caldera collapse. The Cabeza de Vaca pluton formed within the caldera, using the western caldera rim and the annular fracture. Activity occurred in the Paleocene-Eocene, with the pluton dated 63-59.8 mya.
Places inside the annular eclipse included a part of North America including a part of Central Mexico around Mexico City and Orlando and Daytona Beach, Florida in the USA which occurred in the morning hours. In Africa, it included Rosso, Mauritania, the northernmost part of Senegal, Bamako and the southwestern French Sudan (now Mali), the southwesternmost part of Upper Volta (now Burkina Faso) and northern British Gold Coast (now Ghana) which occurred before sunset.
The siphuncle interior is occupied by endocones produced by layered annular deposits expanded back toward the apex, leaving a central tube running down the middle. The short phragmocone is poorly known. Discosorus is found in the Middle Silurian of eastern and arctic North America and as part of the Discosoratidae is derived from the Lowoceratidae which forms a link in the Early Silurian from the Late Ordovician exogastric Faberoceras of the Westonoceratidae.
This annular eclipse is notable in that the path of annularity passed over the North Pole. Land covered in the path include part of Alaska, Canada, and Franz Josef Land, Ushakov Island and Vize Island in the Soviet Union (today's Russia). This was the umbral eclipse number 56 out of 57 of Solar Saros 118, this is the last central solar eclipse, and the penultimate umbral eclipse, with last (ultimate) in 1957.
It is one of only eight medieval round churches in Sweden to survive to this day. It is located not far from Hagby Church, another round church with a similar history which probably pre-dates Voxtorp Church and may have served as a source of inspiration. The church building was altered during the 14th century, when the current choir and probably also sacristy were built. In 1667 the annular thin arch collapsed.
A unique development of Prof. Mathews is the Papercopter, a model helicopter whose 'wing' is a trimmable annular ring which, using rotational aerodynamics to provide good forward flight performance without need for a tail rotor. A model helicopter 'body' is suspended beneath the ring, and uses airflow to stabilise itself in the direction of flight, much like a weather vane. The papercopter design permits flights of approximately 10–14 meters on average.
On July 14, 1749, an annular solar eclipse took place, 2 km west, the center of the greatest eclipse took place, it included the area and lasted 4 min 46 sec at 12:19 UTC. Koulikoro was a commune until March 2012, when it became one of 1126 communes nationwide that were abolished."Le gouvernement ivoirien supprime 1126 communes, et maintient 197 pour renforcer sa politique de décentralisation en cours", news.abidjan.net, 7 March 2012.
In 1824, a man called Vallance took out a patent and built a short demonstration line; his system consisted of a diameter cast iron tube with rails cast in to the lower part; the vehicle was the full size of the tube and bear skin was used to seal the annular space. To slow the vehicle down, doors were opened at each end of the vehicle. Vallance's system worked, but was not adopted commercially.
In an annular drainage pattern streams traces a tangential or greater concentric path along a belt of weak rock so, with others, a roughly traced out ring can be seen. It is best displayed by streams draining a maturely dissected structural dome or basin where erosion has exposed rimming sedimentary strata of greatly varying degrees of hardness, as in the Red Valley, which nearly encircles the domal structure of the Black Hills of South Dakota.
Transparent sections in the shell may allow viewing of liner collapse and milk flow. The annular space between the shell and liner is called the pulse chamber. Milking machines work in a way that is different from hand milking or calf suckling. Continuous vacuum is applied inside the soft liner to massage milk from the teat by creating a pressure difference across the teat canal (or opening at the end of the teat).
Cyclone Jasmine was a long–lived annular tropical cyclone that affected several countries, particularly Vanuatu and Tonga, over a 19‑day span. Cyclone Jasmine developed from an area of disturbed weather on February 1 in the Gulf of Carpentaria. Initially, the storm moved towards the east and across the Cape York Peninsula. As it moved across the South Pacific, earlier existing wind shear conditions lessened, and Jasmine began to strengthen at a faster rate.
The high-pressure compressor (HPC) has a common arrangement for a small turbofan engine, with both axial and a centrifugal stages on the same shaft. There are four axial stages and a fifth centrifugal stage. All the blades and the impeller are made from titanium. The fuel is burned in an annular combustor and the core flow passes through a single-stage high-pressure turbine (HPT) followed by a single-stage low-pressure turbine.
Cranial modification was a procedure that occurred when an individual was still young, usually during infancy because the cranial bones are still soft at this stage and capable of morphing. An infant would be bound between padded boards to cause a tabular effect in the growth of the skull. Another method was to wind a band tightly around the head for an annular effect. Both of these methods produced an elongated shape of the head.
Annular eclipse of the Sun by Phobos as viewed by the Mars Curiosity rover (20 August 2013). An observer situated on the Martian surface, in a position to observe Phobos, would see regular transits of Phobos across the Sun. Several of these transits have been photographed by the Mars Rover Opportunity. During the transits, Phobos's shadow is cast on the surface of Mars; an event which has been photographed by several spacecraft.
The north porch is described by art historian Nikolaus Pevsner as "sumptuously decorated", and intended as the main entrance. Externally it is simple and rectangular with plain side walls. The entrance is a steeply arched portal framed by rich mouldings of eight shafts with stiff-leaf capitals each encircled by an annular moulding at middle height. Those on the left are figurative, containing images representing the martyrdom of St Edmund the Martyr.
The wingspan is about 25 mm. The forewings are pale greyish ochreous, irregularly strewn with light grey transverse strigulae, and a few black specks. The costal edge is pale yellowish and there is a slender light grey dorsal streak from one-fourth to three-fourths, suffused pale yellowish above. The stigmata are small and blackish grey, the plical rather obliquely beyond the first discal, the second discal semi-annular, a clearer space around it.
The suit had a negative buoyancy of . Ballast was attached to the suit's front and could be jettisoned from within, allowing the operator to ascend to the surface at approximately 100 feet (30 m) per minute. The suit also incorporated a communication link and a jettisonable umbilical connection. The original JIM suit had eight annular oil-supported universal joints, one in each shoulder and lower arm, and one at each hip and knee.
It is quite flexible, faintly bluish at the top when young, white when mature with a faint tinge of yellow, smooth, sticky or shiny, and with a cortina at the top forming an annular zone. It is narrower at the apex and usually clavately thickened at the base, stuffed, then hollow. The flesh is white, then slightly yellowish, soft, with mild taste, sometimes slightly bitter when mature, with no distinguishable odor. The mushroom is inedible.
The effect on a lunar eclipse is quite similar, with a few differences. First, the eclipsed body is the Moon and the eclipsing 'body' is the Earth's shadow. Second, since the Earth's shadow at the Moon's distance always is considerably larger than the Moon, a lunar eclipse can never be annular but is always partial or total. Third, the Earth's shadow has two components: the dark umbra and the much brighter penumbra.
Pump pressure, which is also referred to as system pressure loss, is the sum total of all the pressure losses from the oil well surface equipment, the drill pipe, the drill collar, the drill bit, and annular friction losses around the drill collar and drill pipe. It measures the system pressure loss at the start of the circulating system and measures the total friction pressure.Jerome Jacob Schubert, 1995, pp.1-4, 5, 6, 7.
There are three main types of sleeve valves: inline, angle pattern and downflow pattern. Inline sleeve valve can be installed in the pipeline or at the end of the pipeline for free discharge. Inline sleeve valve have an inlet section which allows upstream media to flow into an outer annular area. The flow then takes a 90° turn through the sleeve and collides with flow from the opposite side dissipating the energy.
The bark of the trunk is thornless and greenish- gray with a blaze yellow reflection, with a smooth texture. It exudes a milky white latex exudate profusely. Branches and branchlets are terete in shape with a glabrous or puberulous surface covered with annular scars and a pale yellow tinge. Ficus amplissima typically begins as an epiphyte in the branch of a tree that grows aerial roots that can provide nutrients when they reach soil.
Silver dishes were found out in Sudagylan (near Mingachevir) city, in 1949-1950’s. Ornamentation of a silver cup on an annular leg from Mingachevir of 1st to 4th centuries is characterized by decorative motifs like hollows. Rhythmic repetition of "spoons" can be met in analogical silver cup of the 3rd century from Torpaggala. Image of a deer, which is torn to pieces by a winged lion, is engraved in depth of the cup.
In Australia, Eleven released a short trailer for "The Eclipse", featuring scenes from the various events that occur in the episode. British broadcaster, Channel 5 created their own promo, with the tagline "Four life- changing events. One unmissable episode." "Episode 6646" was aired on 20 May 2013 in Australia and almost a month later on 17 June in the UK. A real annular solar eclipse occurred in Australia ten days before the episode aired there.
Annularity was visible in the Federal States of Micronesia, Nauru, Kiribati, Baker Island, Palmyra Atoll, Kingman Reef, and southwestern California, including the southwestern part of Los Angeles. The duration of annularity at maximum eclipse (closest to but slightly shorter than the longest duration) was 11 minutes, 40.9 seconds in the Pacific. It will have been the longest annular solar eclipse until January 2, 3062, but the solar eclipse of December 24, 1973 lasted longer.
Consumer preferences, Edwards felt, did not necessarily fall into a particular olfactory group (floral, oriental, woody, etc), and could span two or more groups if linked by similar subgroups (i.e. soft florals being akin to floral orientals). This he addressed in the 1992 edition of The Fragrance Manual, the first to feature an annular taxonomy known as the ‘fragrance wheel’, which organized olfactory groups in relation to one another while showing their interchange.
At that time, the MFR noted that Idai had a poorly defined eye, as the eyewall replacement cycle was still underway. Over the next day, Idai's intensity changed very little due to ongoing structural changes within its inner core. At the same time, Idai began to travel in a westerly direction. By 18:00 UTC on 13 March, Idai had developed a large eye and taken on the characteristics of an annular tropical cyclone.
Dora turned back to the southwest on February 2, and briefly weakened before re- intensifying, possibly the result of an eyewall replacement cycle. On February 3, the MFR upgraded Dora to an intense tropical cyclone, estimating peak 10-minute winds of 195 km/h (120 mph). The JTWC meanwhile estimated peak 1-minute winds of 215 km/h (135 mph). While at its peak intensity, Dora resembled an annular cyclone, with a large eye and a symmetrical cloud pattern.
Some manufacturers use a single annular ring magnet, others use a series of single bar magnets in a circular array in their float design. In this design the relative field strength of the north and south poles will be equal to one another and less than that of a dual magnet design. Moreover, the field strength as you travel around the circumference will have high and low spots as you pass between the individual bar magnets.
In frenulates, the trophosome is limited to the post-annular portion of the trunk. While a structural variant of the frenulate trophosome seems to occur, this organ typically consists of two epithelias and blood spaces sandwiched between the basal matrix of the epithelia in which the inner one is composed of bacteriocytes and the outer one is the coelomic lining. The trophosome of Sclerolinum brattstromi consists of a centre of bacteriocytes surrounded by blood space and epithelium.
An annular eclipse appears as a partial eclipse over a region of the Earth thousands of kilometres wide. The path of annularity crossed four states of Mexico (Baja California Sur, Baja California, Sonora and Chihuahua), the United States, the Canadian provinces of Ontario, Nova Scotia and the southeastern tip of Quebec, Azores Islands except Santa Maria Island, and part of Morocco including the capital city Rabat. Niagara Falls was also covered by the path of annularity.
The RAF elected to persevere with the Avon to simplify supply and maintenance, since the Canberra bomber used the same engine.Griffin 2006, pp. 25–26. The RAF sought more thrust than was available from the Avon 100 series; in response Rolls-Royce developed the Avon 200 series engine. This was an almost wholly new design, equipped with a new compressor to put an end to surge problems, an annular combustion chamber, and an improved fuel control system.
Because the lift fan system does not work in cruise, it is dead weight in flight. However, this problem can be greatly mitigated by very thin annular fan blades with a thickness of only 1% chord length. The very thin blades are used because they are optimal for hovering efficiency. For a thin 32-blade fan, the strength of carbon fiber composite material is strong enough, with a weight of only 1.05% of the total aircraft weight.
Firefighting crews quickly responded and sprayed the roof of the turret and the left and right gun barrels, which were still fully loaded with both gunpowder and projectiles, with water. On Kissinger's recommendation, Moosally ordered Turret Two's magazines, annular spaces, and powder flats flooded with 16 tons (14,000 kg) of seawater, preventing the remaining powder from exploding and likely saving the ship. The turret fire was extinguished in about 90 minutes.Schwoebel pp. 8–9; Thompson pp. 107–24.
If the forearm of a young child is pulled, it is possible for this traction to pull the radius into the annular ligament with enough force to cause it to be jammed therein. This causes significant pain, partial limitation of flexion/extension of the elbow and total loss of pronation/supination in the affected arm. The situation is rare in adults, or in older children, because the changing shape of the radius associated with growth prevents it.
The inability to stop down the lens results in the catadioptric lens having a short depth of field. Exposure is usually adjusted by the placement of neutral density filters on the front or rear of the lens. Their modulation transfer function shows low contrast at low spatial frequencies. Finally, their most salient characteristic is the annular shape of defocused areas of the image, giving a doughnut-shaped 'iris blur' or bokeh, caused by the shape of the entrance pupil.
Both contain forms that are annunlate (transversally ribbed) as well as smooth. Other Ordovician families are the broad and beviconic Cyclostomiceratidae and exogastric Bassleroceratidae, rounding out the Ellesmeroceratina. Three families, the Bathmoceratidae, Cyrtocerinidae, and Eothinoceratidae differ from the others in that their connecting rings are greatly thickened inwardly as annular lobes. The Ellesmerocerida gave rise to the Endocerida through Pachendoceras and to the Tarphycerida and Oncocerida through Bassleroceras and is the source for the Orthocerida, Pseudorthocerida, Actinocerida, and Discosorida.
This list of solar eclipses visible from the Philippines enumerates the solar eclipse that have been and will be seen over the Philippines. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby obscuring Earth's view of the Sun. Eclipses can be total, annular, or partial. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness for a brief moment in time.
Joseph Betts was an English mathematician: he held the Savilian Chair of Geometry at the University of Oxford in 1765. Betts was a Fellow of University College, Oxford. He had previously sought election as Savilian Professor of Astronomy with the support of the Earl of Litchfield, the Earl of Halifax and the Earl of Bute. He thanked his patrons for that failed attempt in the dedication to an engraving of the annular solar eclipse of 1 April 1764.
The test vehicle was a 3/10-scale model of the Miles E.24/43 design except for the omission of the distinctive annular air intake of the full-scale aircraft.Flight Trials of a Rocket-propelled Transonic Research Model :The R.A.E.-Vickers Rocket Model(HMSO 1954) To maintain the center of gravity (c.g.) it was necessary to include a large balance weight (a!most 1/10 of total all-up weight) in the foremost section of the nose.
A partial solar eclipse will occur on December 6, 2086. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A partial solar eclipse occurs in the polar regions of the Earth when the center of the Moon's shadow misses the Earth. The antumbral (annular) shadow of the moon will pass just above the north pole of the earth.
Varves are a depositional feature of a fluvio-glacial movement. They are layers of annular sediment deposits. The sizes of the sediments vary and depend on the volume of the streams, but are usually associated with mud deposits (silt and clay). The color and amount of the sediment deposited also varies depending upon the season; summer deposits typically have larger volumes of deposition and are characterized as being light, whereas winter deposits are usually the opposite.
Annularity was visible from Ogasawara, Tokyo and South Pacific Mandate (the part now belonging to Marshall Islands) in Japan, and Gilbert and Ellice Islands (the part now belonging to Kiribati). The duration of annularity at maximum eclipse (closest to but slightly shorter than the longest duration) was 12 minutes, 0.33 seconds in the Pacific Ocean. It was the longest annular solar eclipse since December 25, 1628, but the Solar eclipse of December 14, 1955 lasted longer.
In 1979, TAM developed the Casing Annulus Packer (CAP) product line for annular gas migration control. In 1981, TAM developed a hydrological test tool for use in modeling the various aquifers at the Hanford Nuclear Site in Washington. The tool was a multiple packer configuration that allowed selective open hole testing of a distinct test interval. In addition, short intervals were isolated above and below to allow pressure monitoring to verify isolation within the test interval.
Discrete lipid domains with differing composition, and thus membrane fluidity, can coexist in model lipid membranes; this can be observed using fluorescence microscopy. The biological analogue, 'lipid raft', is hypothesized to exist in cell membranes and perform biological functions. Also, a narrow annular lipid shell of membrane lipids in contact with integral membrane proteins have low fluidity compared to bulk lipids in biological membranes, as these lipid molecules stay stuck to surface of the protein macromolecules.
Electric spark ionization is used to produce gas phase ions from a solid sample. When incorporated with a mass spectrometer the complete instrument is referred to as a spark ionization mass spectrometer or as a spark source mass spectrometer (SSMS). A closed drift ion source uses a radial magnetic field in an annular cavity in order to confine electrons for ionizing a gas. They are used for ion implantation and for space propulsion (Hall effect thrusters).
Then Soulik rapidly intensified onto a severe typhoon, and on the next day, Soulik reached its peak intensity, with winds of , and remained that intensity for several days. It also began to display some annular characteristics. After passing the Ryukyu Islands early on 22 August, the storm gradually weakened due to low sea-surface temperatures. On August 23, Soulik made landfall over Haenam County, South Jeolla Province of South Korea at around 23:00 KST (14:00 UTC).
The next day, Sergio began a third eyewall replacement cycle, falling below major hurricane strength. At the same time, the system unexpectedly assumed some annular characteristics. Over the next few days, the cyclone curved from the southwest to the northeast, weakening into a tropical storm on October 9\. Sergio made landfall as a tropical storm on October 12 on the Baja California Peninsula, and later in northwestern Mexico as a tropical depression before dissipating early on October 13\.
The eye feature became more pronounced throughout the day, with convection consolidating inward and becoming more symmetric. Accordingly, the FMS accordingly upgraded Pat to a Category 3 severe tropical cyclone by 18:00 UTC. The system became annular in nature on February 10, characterized by a lack of prominent banding features and uniform convection which surrounded its wide eye. Pat reached its peak intensity at 06:00 UTC that day as it began turning to the southwest.
Thursophyton is a genus of terrestrial vascular plants which flourished in the Middle Devonian period. These plants consisted of aerial stems branching dichotomously, trichotomously or pseudomonopodially, at least the main axes clothed in spirally arranged spines up to 7 mm long, which are not leaves as they are not vascularised and leave no scar when removed. The stems contain an elliptical exarch xylem having both annular and spirally thickened tracheids; very little is known about the sporangia.
Secondly, chemoselective inner ring closure by fluorocyclization between 6-hydroxytrytophan and cysteine was achieved by intra-annular Savige-Fontana reaction. This requires a solid phase peptide synthesis-compatible, and methyliminodiacetic acid (MIDA), a boron protecting group, orthogonal amino acid in 5 steps. As a final step, enantioselective oxidation at the tryptathionine linkage was achieved using a bulky organic oxidizing agent and an optimized solvent system to afford the desired the bio- reactive (R)-enantiomer sulfoxide, completing the total synthesis.
Mill foundations are located on the bank of a creek and include rendered brick concentration tanks and two concrete buddle bases each in diameter with four outer annular channels of concrete. Adjacent to and immediately south of the buddles is a large rendered brick settling pond. There is minimal evidence of the mill building/s or other plant. The site of a large tailings dump is still evident to the south and east of the mill.
For many years it was believed that this missile used a turbojet engine during the sustained flight; after the Russian and the Western media gained access to its performance characteristics, it was understood that its propulsion system was a ramjet.Scott, Richard Russia's 'Shipwreck' missile enigma solved Jane's Naval Forces News. 10 September 2001 The P-700 has a distinctive annular air intake in the nose. Maximum speed is believed to be between Mach 1.6 to Mach 2.5.
A wide, annular depression or moat about deep surrounds the base of Olympus Mons and is thought to be due to the volcano's immense weight pressing down on the Martian crust. The depth of this depression is greater on the northwest side of the mountain than on the southeast side. Olympus Mons is partially surrounded by a region of distinctive grooved or corrugated terrain known as the Olympus Mons aureole. The aureole consists of several large lobes.
The live cornea has a thin layer removed therefrom, leaving an exposed internal surface thereon. Then, either the surface or thin layer is exposed to the laser beam along a predetermined pattern to ablate desired portions. The thin layer is then replaced onto the surface. Ablating a central area of the surface or thin layer makes the cornea less curved, while ablating an annular area spaced from the center of the surface or layer makes the cornea more curved.
Annular pancreas is a rare condition in which the second part of the duodenum is surrounded by a ring of pancreatic tissue continuous with the head of the pancreas. This portion of the pancreas can constrict the duodenum and block or impair the flow of food to the rest of the intestines. It is estimated to occur in 1 out of 12,000 to 15,000 newborns. The ambiguity arises from the fact that not all cases are symptomatic.
In April 1764 Bliss made observations of an annular (solar) eclipse visible from Greenwich. Many of the observations made by Bliss were considered potentially useful for solving the longitude problem, important for cartography and ocean navigation, and were therefore bought by the Board of Longitude from his widow Elizabeth Bliss (née Hillman). His Greenwich observations were not published until 1805 when they were included as a supplement in an edition by Thomas Hornsby on the observations of Bradley.
Bickley has an average winter rainfall of , and Kalamunda has an average winter rainfall of . Perth's winter rainfall is influenced by the southern annular mode (SAM). When the SAM is positive, rainfall in Perth is decreased, and when the SAM is negative, rainfall in Perth is increased. While snow has never been recorded in the Perth CBD, light snowfalls have been reported in outer suburbs of Perth in the Perth Hills around Kalamunda, Roleystone and Mundaring.
The dye cell is placed in the middle, providing a more even distribution of pumping light, and more efficient transfer of energy. The hollow flashlamp also has lower inductance than a normal flashlamp, which provides a shorter flash discharge. Rarely, a "coaxial" design is used for dye lasers, which consists of a normal flashlamp surrounded by an annular shaped dye cell. This provides better transfer efficiency, eliminating the need for a reflector, but diffraction losses cause a lower gain.
The stems are several mm to several cm in diameter and several cm to several metres long, erect or arched, dichotomizing occasionally, furnished with true roots at the base.Hueber 1992, p. 491 (Baragwanathia) and 492 (Drepanophycus) Vascular bundle an exarch actinostele, tracheids of primitive annular or helical type (so-called G-type). Leaves are unbranched microphylls several mm to 2 cm or more long with a single prominent vascular thread, arranged spirally to randomly on the stem.
Pustular lesions with central necrosis on the left leg of a patient with Sweet's syndrome associated with Crohn's disease. Punch biopsy of a skin lesion showing neutrophilic infiltration in the dermis, with no evidence of vasculitis (same patient with Crohn's disease). Acute, tender, erythematous plaques, nodes, pseudovesicles and, occasionally, blisters with an annular or arciform pattern occur on the head, neck, legs, and arms, particularly the back of the hands and fingers. The trunk is rarely involved.
The Twist Compression Tester ("TCT") is a hydraulically operated bench-top apparatus used to evaluate the level of friction and/or wear between two materials under lubricated or non-lubricated conditions. Under controlled conditions, a rotating annular specimen is brought into contact with a non- rotating flat specimen. Specimens can be prepared from die materials, sheet or plate materials, metals or plastics. The applied normal force and the torque are measured, and the coefficient of friction is calculated.
Submerged tube boiler To avoid the problem of exposed fire-tubes above the water level, the submerged multi-tube boiler may be used. The upper boiler shell is extended upwards in an annular ring, so as to always maintain the whole length of the tubes submerged. Used in steam wagons and similar, where the water-level may be disturbed as the vehicle climbs a hill. The relatively rare Fowler steam wagons used a boiler of this form.
The stubborn Tropical Depression Tina dissipated on October 11, shortly after entering the central Pacific. Similar to Hurricane Isabel, Tina displayed annular characteristics. Due to its erratic track and slow motion, Tina was alive from September 17 to October 11— a span of 24 days. This is the record for the eastern Pacific Ocean, smashing the east/central record of 20 days held by Hurricane Fico in the 1978 season and surpassing Typhoon Rita's west Pacific 1972 record.
The eye soon disappeared on satellite imagery, believed to be from an eyewall replacement cycle, and Darby's winds weakened to about 105 mph (170 km/h). A 25-mile (40 km) eye next developed, and on July 26, the hurricane re-intensified to reach peak winds of 115 mph (185 km/h). For a 30-hour period, Darby attained the characteristics of an annular hurricane, retaining a well-defined structure with few banding features for an extended period.
Z.501 in flight The aircraft had a very slim fuselage, a high parasol wing and a single wing-mounted engine nacelle. In the prototype a 560 kW (750 hp) inline Isotta Fraschini Asso-750.RC engine was fitted, with an annular (circular) radiator that made the installation resemble a radial engine, although it was actually a liquid-cooled inline. Some versions of other planes such as the Ju 88 and Fw 190D had this same feature.
The larger Jendrassik Cs-1, with a predicted output of 1,000 bhp, was produced and tested at the Ganz Works in Budapest between 1937 and 1941. It was of axial-flow design with 15 compressor and 7 turbine stages, annular combustion chamber and many other modern features. First run in 1940, combustion problems limited its output to 400 bhp. In 1941, the engine was abandoned due to war, and the factory was turned over to conventional engine production.
This equation has the same structure as the one for the point monopole shown above. Although the amplitude factor A replaces the dimensionless volumetric flow rate in these equations, the speed dependence strongly confirms the monopole-like characteristics of the Hartmann whistle. A cousin to the Hartmann whistle is shown in the figure on the right, the Galton whistle. Here the cavity is excited by an annular jet, which oscillates symmetrically around the sharp edges of the cavity.
E=extracellular space; P=plasma membrane; I=intracellular space An integral membrane protein (IMP) is a type of membrane protein that is permanently attached to the biological membrane. All transmembrane proteins are IMPs, but not all IMPs are transmembrane proteins. IMPs comprise a significant fraction of the proteins encoded in an organism's genome. Proteins that cross the membrane are surrounded by annular lipids, which are defined as lipids that are in direct contact with a membrane protein.
The flowers are hermaphroditic, having a colour ranging from yellow to green and a double perianth radial symmetry. They are composed of an entire annular calyx, five almost fully developed sepals, a corolla with five petals 2.5 mm long, with five stamens and five or six carpels that enclose the ovary. The style is not recognizable and the stigma is established. The fruits have an almost spherical oval drupe, with a diameter of about 5 mm.
Development of the craft was not straightforward, having posed several challenges and difficulties that needed to be overcome from the onset.Paine and Syms 2012, p. 75. Early on, one criticism of the Model A was that the single annular peripheral jet engine would be incapable of adequate pitch and roll stability while the diagonal stability jets featured on Cockerell's original model had been eliminated; however Saunders-Roe's aerodynamics office were confident that the design was good.
Waldeyer's tonsillar ring is an anatomical term collectively describing the annular arrangement of lymphoid tissue in the pharynx. Waldeyer's ring circumscribes the naso- and oropharynx, with some of its tonsillar tissue located above and some below the soft palate (and to the back of the oral cavity). It is believed that Waldeyer's ring prevents the invasion of microorganisms from going into the air and food passages and this helps in the defense mechanism of the respiratory and alimentary systems.
Vail argued that the Earth once had rings like Saturn's, in what became known as the "Vailan theory" or "annular theory". His 1886 "Canopy Theory" proposed that the Earth had been ringed by a toroidal mass of ice, which he named the "firmament", following the usage in Genesis 1:6-8. Vail supposed that this could explain Noah's Flood, as he described in his 1874 book The Earth's Aqueous Ring: or The Deluge and its Cause.Vail, Isaac N. 1874.
A single reverse-flow canister featuring a more-or-less standard spark plug for ignition was employed. Had the engine been further developed, annular combustion chambers along with a second power turbine might have improved power and economy even more. The transmission has an "idle" position instead of "neutral". After the user testing period completed, Chrysler collected all of the cars, destroying 40 out of the original 50 Chrysler kept 2,then sending the remaining examples to museums.
The basic design of the single shaft Astazou has a two-stage compressor, with the first stage an axial and the second stage a radial design. It has an annular combustion chamber, after which the hot exhaust enters a three-stage axial turbine. Maximum rpm was later raised to 43,500. Production turbines have a reduction gear in front of the air inlet, reducing propeller speed to 1,800, 2,080, 2,200, 0r 2,400 rpm, or 6,000 rpm in the helicopter version.
The engine controls itself automatically, so the pilot only needs to set the desired rpms. Handley Page HP.137 Jetstream, with twin Astazou XIV, showing the distinctive annular air inlet and long reduction gear housing As of the Astazou X, the engine received a second axial compressor stage. This was the engine for the Potez 840. The Astazou XIV and XVI were also marketed by Rolls- Royce Turboméca International Ltd under the names AZ14 and AZ16, respectively.
The flow then travels downstream through an exit spool on the downstream end. The angle pattern sleeve valve is installed at a 90° bend in place of an elbow. Angle pattern sleeve valves employ a similar design as the inline sleeve valve by creating an outer annular area to contain the media and a sleeve with tapered nozzles to pass the flow. The difference is that the flow direction after passing through the sleeve changes by 90°.
The synovial membrane of the elbow joint is very extensive. On the humerus, it extends up from the articular margins and covers the coronoid and radial fossae anteriorly and the olecranon fossa posteriorly. Distally, it is prolonged down to the neck of the radius and the superior radioulnar joint. It is supported by the quadrate ligament below the annular ligament where it also forms a fold which gives the head of the radius freedom of movement.
With a maximum length of annularity duration of 12 minutes and 9.17 seconds, this is the longest solar eclipse in the millennium, also the longest duration in Saros 141, one of the longest eclipse that ever happened. The annular path begins in northern Africa,then passing Maldives (near the maximum eclipse), then crosses just southern edge of Sri Lanka, then the track continues to some countries in Indochina and the track ends just slightly after the track passes Taiwan.
In organic chemistry annulation (from the Latin anellus for "little ring"; occasionally annelation) is a chemical reaction in which a new ring is constructed on a molecule. :Annulation: A intramolecular ring closing B transannulation C cycloaddition Examples are the Robinson annulation, Danheiser annulation and certain cycloadditions. Annular molecules are constructed from side-on condensed cyclic segments, for example helicenes and acenes. In transannulation a bicyclic molecule is created by intramolecular carbon-carbon bond formation in a large monocyclic ring.
Using a separator transmission coupled to the compressor rotor, the upper-mounted equipment carrier for fuel pump & control-pressure transmitter as well as the oil pump block were driven. ;Blow-off system Initially, 4 rectangular blow-off flaps (valves) were installed; later they were changed to 8 round flaps. Further during the re-design process, specifically from prototype engine V-07 onwards, this implementation was changed to a different, better controllable system which involved an annular blow-off belt.
The problem was ultimately solved by the introduction of the pointed arch for the transverse and wall ribs – the pointed arch had long been known and employed, on account of its much greater strength and of the less thrust it exerted on the walls. When employed for the ribs of a vault, however narrow the span might be, by adopting a pointed arch, its summit could be made to range in height with the diagonal rib; and, moreover, when utilized for the ribs of the annular vault, as in the aisle round the apsidal termination of the choir, it was not necessary that the half ribs on the outer side should be in the same plane as those of the inner side; for when the opposite ribs met in the centre of the annular vault, the thrust was equally transmitted from one to the other, and being already a broken arch the change of its direction was not noticeable. Rib vault of church Sint- Niklaaskerk in Ghent, Belgium. Top of the rib-vaulted ceiling over the nave of Salisbury Cathedral.
This design was similar in layout but somewhat smaller and powered by two of the largest displacement (at 44.5 litres/2,700 cu. in.) single-block liquid-cooled aviation engines placed in mass production in Germany, the DB 603 inverted V12 engine. As designed by Heinkel, these engines' nacelle accommodations featured annular radiators similar to the ones on the Jumo 211-powered Junkers Ju 88A, but considerably more streamlined in appearance, and which, after later refinement to their design, were likely to have been unitized as a Heinkel-specific Kraftei engine unit-packaging design. Nearly identical-appearance nacelles, complete with matching annular radiators, were also used on the four prototype He 177B prototype airframes built in 1943–44, and the six ordered prototypes of Heinkel's He 274 high-altitude strategic bombers with added turbochargers. The early DB 603 subtypes had poor altitude performance, which was a problem for Heinkel's short-winged design, but Daimler had a new "G" subtype of the DB 603 powerplant meant to produce 1,400 kW (1,900 PS) take-off power apiece under development to remedy the problem.
Several other geometrical solutions to Apollonius' problem were developed in the 19th century. The most notable solutions are those of Jean-Victor Poncelet (1811) and of Joseph Diaz Gergonne (1814). Whereas Poncelet's proof relies on homothetic centers of circles and the power of a point theorem, Gergonne's method exploits the conjugate relation between lines and their poles in a circle. Methods using circle inversion were pioneered by Julius Petersen in 1879; one example is the annular solution method of HSM Coxeter.
Indotyphlops braminus, commonly known as the brahminy blind snake and other names, is a nonvenomous blind snake species found mostly in Africa and Asia, but has been introduced in many other parts of the world. They are completely fossorial (i.e., burrowing) animals, with habits and appearance similar to earthworms, for which they are often mistaken, although close examination reveals tiny scales rather than the annular segments characteristic of true earthworms. The specific name is a Latinized form of the word Brahmin.
Jarrett (1976)Lewis, P.; British Aircraft 1809-1914, Putnam, 1962, pages 340-343. A non-flying replica later appeared in the 1965 film Those magnificent men in their flying machines and is now on display at the Newark Air Museum. Lee and Richards continued experimenting with models and Richards especially further developed the aerodynamic theory of the annular wing. They developed a form having a circular lower wing with an auxiliary plane above the front half of the main wing.
This plain is surrounded by the High Atlas, the Anti-Atlas, the Sea of Atlas (Atlantis Thalassa, today's Atlantic Ocean). Because of this isolated position, Hübner argued, this plain was called Atlantis Nesos, the Island of Atlas by ancient Greeks before the Greek Dark Ages. The Amazigh (Berber) People actually call the Souss-Massa plain island. Of major archaeological interest is the fact that in the North-West of the Souss-Massa plain a large annular caldera-like geomorphologic structure was discovered.
A linear transformer driver (LTD) is an annular parallel connection of switches and capacitors designed to deliver rapid high power pulses. The LTD was designed at the Institute of High Current Electronics (IHCE) in Tomsk, Russia. The LTD is capable of producing high current pulses, up to 1 mega amps (106 ampere), with a risetime of less than 100 ns. This is an improvement over Marx generator based pulsed power devices which require pulse compression to achieve such fast risetimes.
The vortex is formed by placing a semi-porous wall in front of the desired location of the fuel vortex but leaves room along its sides for hydrogen propellant. Propellant is then pumped inside the reactor cavity along an annular inlet region. A dead space then develops behind the semi-porous wall; due to viscous and shear forces, a counter toroidal rotation develops. Once the vortex develops, fissile fuel can be injected through the semi-porous plate to bring the reactor critical.
As such, Styx has no annular eclipses, its widest axis being more than 10 arcseconds larger than the Sun at its largest. However, Kerberos, although slightly larger, cannot make total eclipses as its largest minor axis is a mere 32 arcseconds. Eclipses by Kerberos and Styx will entirely consist of partial and hybrid eclipses, with total eclipses being extremely rare. The next period of mutual events due to Charon will begin in October 2103, peak in 2110, and end in January 2117.
Currently the genus is restricted to a smaller but still large group of species that primarily grow on wood, causing a white rot, but other taxa occur on burnt ground following forest fires or camp fires, on peaty or forest soil, but none are known to be mycorrhizal. Many species have prominent partial veils and form an annulus or annular ring on their stipes. None of the species have purplish or purplish brown spore prints. None form acanthocytes on their mycelia.
One vacuum filler pumps the filling product while a second one deposits the skin (a paste containing alginate) via an annular gap. This is solidified by means of a fixing solution containing calcium ions. Depending on the degree of automation, the portions can be hung or collated or transported further for continuous thermal treatment or packaging. The most important advantage of the ConPro systems in comparison to traditional production methods is that sausage skins or casings no longer have to be changed.
The stapes or stirrup is a bone in the middle ear of humans and other mammals which is involved in the conduction of sound vibrations to the inner ear. This stirrup-shaped bone is connected to the oval window by its annular ligament, which allows the footplate to transmit sound energy through the oval window into the inner ear. The stapes is the smallest and lightest bone in the human body, and is so-called because of its resemblance to a stirrup ().
4 A mechanical model of ceramic forming correctly predicts: (left) the load/displacement curve during cold pressing, (centre) the density (void ratio) map within a formed piece and (right) the dark annular region evidenced on the bottom of a formed piece. The mechanical model developed by Piccoloraz et al. (2006 a;b) permits the description of the forming process (Fig. 4). The INTERCER2 research project is aimed to develop novel constitutive descriptions for ceramic powders and more robust implementation in a numerical code.
"American Standard for Cast-Iron Pipe Centrifugally Cast in Metal Molds, for Water or Other Liquids", American Water Works Association, A21.6-1962 (AWWA C106-62), 1962. When casted with sand molds, two types of manufacturing processes were used. In the first method, a metal pattern was typically positioned in a metal flask and molding sand was rammed into the annular space between the flask and pattern. The pattern was then removed for casting of the pipe using molten grey iron.
Uniquely among the Rhynie chert plants, aerial stems bore rigid hairs or spines made up of single cells. Stems appear to have grown from coiled (circinnate) tips, in a manner similar to modern ferns. Stems contained circular exarch xylem strands with tracheids showing both annular and spiral thickening. The upright spore-forming organs or sporangia were made up of two 'valves', the larger one facing away from the stem and bearing hairs, the smaller facing towards the stem and apparently not bearing hairs.
Special Rail Drill Bits with Weldon Shank manufactured by BDS Maschinen GmbH (Germany) The Rail Twist Drill or Rail Drill Bits are the types of Spiral Drill Bits. These drill bits are ideal for making smaller diameter holes which are not possible with TCT Annular Cutters. These drill bits can make holes as low as 2 mm diameter. Mostly 6 to 8 mm diameter holes required for earthing cables or attaching sensors to rail tracks are made by twist drill bits.
The bimetallic coin design was inspired by the graceful architecture of the library's Jefferson Building. The outer ring is stamped from a sheet of gold, then a solid core of platinum is placed within the ring. Then, the gold ring and platinum core are simultaneously stamped forming an annular bead where the two precious metals meet. The obverse depicts the hand of Minerva, the Goddess of Wisdom, raising the torch of learning aside the dome of the Thomas Jefferson Building.
The nerve also provides sensory branches that travel to the periosteum of the lateral epicondyle, the anterior radiohumeral joint, and the annular ligament. It provides motor function through innervation to most extensor muscles of the posterior arm and forearm. Therefore, it is extremely important in upper body extremity movement and can cause significant pain to patients presenting with radial tunnel syndrome. Unlike carpal tunnel syndrome, radial tunnel syndrome does not present tingling or numbness, since the posterior interosseous nerve mainly affects motor function.
Boyne 2001, p. 9. Two were built, but only one was flown, making its maiden flight on June 11, 1920. The aircraft demonstrated good performance, reaching , but the radical annular radiator was unsuccessful, having to be replaced to a more conventional unit. Because of its performance, it was decided to modify the VCP-1 to a racing aircraft, replacing the Wright-Hispano engine with a Packard 1A-2025 V12 engine, becoming the VCP-R (later again rebuilt as the Verville R-1 Racer).
166 and not in any way directly related to the entirely separate He 277 advanced bomber design project, which by the summer of 1943 was considered to be Heinkel's Amerikabomber aviation contract contender. The first development of the original He 177A to fly with four "individual" engines – using a quartet of He 219-style annular radiators to cool its likely-unitized Daimler-Benz DB 603 powerplants – was the second He 177B prototype, the He 177 V102, on December 20, 1943.
A snap-fit is an assembly method used to attach flexible parts, usually plastic, to form the final product by pushing the parts' interlocking components together. There are a number of variations in snap-fits, including cantilever, torsional and annular. Snap-fits, as integral attachment features, are an alternative to assembly using nails or screws, and have the advantages of speed and no loose parts. Snap-fit connectors can be found in everyday products such as battery compartment lids, snap fasteners and pens.
The first application of STEM to the imaging of biological molecules was demonstrated in 1971.Wall, J.S. (1971) A high resolution scanning electron microscope for the study of single biological molecules. PhD thesis, University of Chicago The advantage of STEM imaging of biological samples is the high contrast of annular dark- field images, which can allow imaging of biological samples without the need for staining. STEM has been widely used to solve a number of structural problems in molecular biology.
In STEM, bright-field detectors are located in the path of the transmitted electron beam. Axial bright-field detectors are located in the centre of the cone of illumination of the transmitted beam, and are often used to provide complementary images to those obtained by ADF imaging. Annular bright-field detectors, located within the cone of illumination of the transmitted beam, have been used to obtain atomic resolution images in which the atomic columns of light elements such as oxygen are visible.
In the retinal ganglion cells there are two types of response, depending on the receptive field of the cell. The receptive fields of retinal ganglion cells comprise a central, approximately circular area, where light has one effect on the firing of the cell, and an annular surround, where light has the opposite effect. In ON cells, an increment in light intensity in the centre of the receptive field causes the firing rate to increase. In OFF cells, it makes it decrease.
This form of psoriasis is characterized by an acute onset of numerous pustules on top of tender red skin. This skin eruption is often accompanied by a fever, muscle aches, nausea, and an elevated white blood cell count. Annular pustular psoriasis (APP), a rare form of GPP, is the most common type seen during childhood. APP tends to occur in women more frequently than in men, and is usually less severe than other forms of generalized pustular psoriasis such as impetigo herpetiformis.
The planet and sun gears mesh so that their pitch circles roll without slip. A point on the pitch circle of the planet gear traces an epicycloid curve. In this simplified case, the sun gear is fixed and the planetary gear(s) roll around the sun gear. An epicyclic gear train can be assembled so the planet gear rolls on the inside of the pitch circle of a fixed, outer gear ring, or ring gear, sometimes called an annular gear.
Solar Saros 147, repeats every 18 years, 11 and 1/3 days, and contains 80 events in which 40 will be partial eclipses and 40 will be annular. There are no total or hybrid eclipses in this series. It includes 25 central solar eclipses with a penumbral internal contact (penumbra northern and southern limits), starting in 2129 and ending in 2562. Lunar Saros 140 interleaves with this solar saros with an event occurring every 9 years 5 days alternating between each saros series.
The bullous stage of BP shows vesicles and bulla, appearing on apparently normal or erythematous skin, predominantly at the flexural aspects of the extremities and the lower trunk. Mucosal lesions, which typically are erosions of the oral mucosa, are present in 10 to 30 percent of patients. Occasionally, the blister fluid becomes blood-tinged. The blisters are tense, about 1–4 cm in diameter, leaving eroded and crusted areas, together with urticarial and infiltrated papules and plaques in an annular or figurate pattern.
The maximum observed temperature has been 36 °C. Average annular precipitation is 243 mm (24% in the spring, 1% in the summer, 33% in the fall, and 44% in the winter). Boroujen has one of the highest elevation among all Iran cities, making it rich and fruitful in terms of vegetable and animal environment. The city is located in a valley with the same name which has a total area of 580 m² in the eastern part of Chahar Mahaal and Bakhtiari province.
Partial solar eclipses occur when the viewer is inside the penumbra. Each icon shows the view from the centre of its black spot, representing the Moon (not to scale) The eclipse magnitude is the fraction of the Sun's diameter that is covered by the Moon. For a total eclipse, this value is always greater than or equal to one. In both annular and total eclipses, the eclipse magnitude is the ratio of the angular sizes of the Moon to the Sun.
The light curve of DS Andromedae shows a main eclipse when the secondary star passes in front of the primary, and a secondary eclipse when the opposite occurs. This cycle repeats with a periodicity slightly over one day. Since the system is almost exactly edge-on the secondary eclipse is total, and allows the determination of the spectral type of the secondary component. The primary eclipse is annular as the smaller secondary passes in front of the hotter brighter primary.
A mechanical seal would most likely be created out of an annular elastomeric material through which the nozzle must pass during refueling, preventing vapors from escaping alongside the nozzle. A liquid seal is created by the design of the filler pipe, which creates a seal with the liquid flowing into the tank. Since the liquid fills the entire pipe, no emissions can escape during refueling. A liquid seal is usually used for smaller vehicles, while the mechanical seal is used for larger vehicles.
Ringtail, also known as tail necrosis,Ringtail at Rat Guide is an epidermal disease that may occur in rats, mice, hamsters and other rodents.L.Crippa et al., Ringtail in suckling Munich Wistar Fromter rats: a histopathologic study In affected individuals, the tail swells as a consequence of annular constrictions along its length (hence the name "ringtail") and subsequent dehydration; in the most severe cases, the process may end up in the tail becoming gangrenous and dropping off. Feet may also swell and redden.
Valvular disease is caused primarily by valvular lesions stemming from infections, especially rheumatic fever (Streptococceus pyogenes), which can result in either a regurgitant or stenotic valve, or both. Regurgitation results from lesions on the valve edges or annular dilation which causes backwards-flow of the blood. Stenosis results in thickened leaflets due to heavy fibrosis of the valve so blood cannot flow through normally. Stenotic valves require valve replacement however conventional valves have decreased lifespan due to an inflammatory response.
In industry, cavitation is often used to homogenize, or mix and break down, suspended particles in a colloidal liquid compound such as paint mixtures or milk. Many industrial mixing machines are based upon this design principle. It is usually achieved through impeller design or by forcing the mixture through an annular opening that has a narrow entrance orifice with a much larger exit orifice. In the latter case, the drastic decrease in pressure as the liquid accelerates into a larger volume induces cavitation.
Pelargonium × hortorum, (also called zonal geranium, garden geranium), is a nothospecies of Pelargonium most commonly used as an ornamental plant. It is a hybrid between Pelargonium zonale and Pelargonium inquinans. They are the group of Pelargonium cultivars, with leaves marked with a brown annular zone and inflorescence in the form of large balls of tight flowers, usually red, pink or white. These are the most common geraniums of garden centers and florists, sold in pots for windowsills and balconies or planted in flowerbeds.
While drilling an oil or gas well, the top of the wellbore is lined with a casing. The drill string runs through the casing. The annular (ring-shaped) region between the casing and the drill stem is filled with drilling mud which provides hydrostatic pressure to keep the formation fluid from coming up the wellbore. If the pressure of the formation fluid exceeds the hydrostatic pressure of the drilling mud, the oil or gas can blow out of the wellbore.
A particularly important example in animal cells is cholesterol, which helps strengthen the bilayer and decrease its permeability. Cholesterol also helps regulate the activity of certain integral membrane proteins. Integral membrane proteins function when incorporated into a lipid bilayer, and they are held tightly to the lipid bilayer with the help of an annular lipid shell. Because bilayers define the boundaries of the cell and its compartments, these membrane proteins are involved in many intra- and inter-cellular signaling processes.
The Becker Mewis Duct is a version based on an eccentric annular nozzle fitted between the hull and the propeller, supported by a number of flow directing radial vanes, each of which is angled to optimise inflow direction. The design is patented and has been in use since 2009. The Schneekluth Wake Equalising Duct is a version using two semicircular nozzles, one on each side of the hull, centred above the shaft centreline, and angled to provide contra-rotational outflow swirl.
A hybrid solar eclipse occurred on October 3, 1986. A hybrid eclipse starts and ends as an annular, but is total in the middle around the point of greatest eclipse. Totality occurred for a very short time (calculated at 0.08 seconds) in an area in the Atlantic Ocean, just east of the southern tip of Greenland. The path, on the surface of the Earth, was a narrow, tapered, horse-shoe, and visible only from a thin strip between Iceland and Greenland.
These changes are more pronounced as time progresses after injury, and are evidenced by end plate osteophytosis, disc damage, disc narrowing, desiccation and disc bulging. “A retrolisthesis hyperloads at least one disc and puts shearing forces on the anterior longitudinal ligament, the annular rings, nucleus pulposus, cartilage end plates and capsular ligaments. The bulging, twisting and straining tissues attached to the endplates pull, push and stretch it. It is worsened with time, becoming irreversible.” This is the etiology of degenerative joint disease.
The elements are made up of zig zag corrugated plates pressed into a steel basket giving sufficient annular space in between for the gas to pass through. These plates are corrugated to give more surface area for the heat to be absorbed and also to give it the rigidity for stacking them into the baskets. Hence frequent replacements are called for and new baskets are always kept ready. In the early days, Cor-ten steel was being used for the elements.
A total solar eclipse will occur on November 14, 2031. It is a hybrid event, with portions of its central path near sunrise and sunset as an annular eclipse. A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon's apparent diameter is larger than the Sun's, blocking all direct sunlight, turning day into darkness.
Integrated into a single component and inserted into the intake bullet, it worked directly on the shaft, where it was coupled with the engine-rotor using a separate transmission assembly for the starter. ;Oil tank Originally to be mounted beneath the engine, it was re-designed as an annular oil tank. The new mounting place was now in the diffuser area, in front of the air-intake casting. ;Air-intake casting This component was made from light metal cast design.
Through 1988, the oldest J402 engine fired in a Harpoon was over eleven years old, exceeding the original five year "wooden round" requirement. The J402-CA-400 was a single-shaft engine, with one axial compressor stage and one centrifugal compressor stage. The compressed air was combusted in an annular combustor, and then passed through a single high-pressure turbine stage before being exhausted. Because the engine was designed for a one-time use missile, its service life was only one hour.
Mcnamaraspis kaprios is an arthrodiran placoderm of the Family Plourdosteidae that inhabited the ancient reef system of north Western Australia during the Frasnian epoch of the Late Devonian period (c. 380-375 million years ago). The type specimen was found and described by John A. Long from the Gogo Formation near Fitzroy Crossing. This fossil fish showed new anatomical features in arthrodires, like the well-preserved annular cartilages of the snout, previously inferred to be present by Erik Stensiö of Sweden.
Although conventional (annular) Hall thrusters are efficient in the kilowatt power regime, they become inefficient when scaled to small sizes. This is due to the difficulties associated with holding the performance scaling parameters constant while decreasing the channel size and increasing the applied magnetic field strength. This led to the design of the cylindrical Hall thruster. The cylindrical Hall thruster can be more readily scaled to smaller sizes due to its nonconventional discharge- chamber geometry and associated magnetic field profile.
SD 10C - Was a German made fragmentation bomb that was constructed differently than the SD 10A but its dimensions and performance was similar. The body was constructed of cast steel with 9 annular grooves machined in the case to enhance fragmentation. The nose had a centrally located fuze and the tail was machined to form a base for the tail unit. The tail was then closed by a steel plate shrunk into position and crimped onto four indentations in the body.
In 1970, Albert Crewe developed the high-angle annular dark- field imaging (HAADF) imaging technique in a scanning transmission electron microscope. Using this technique, he visualized individual heavy atoms on thin amorphous carbon films. In 2010 Krivanek and colleagues reported several technical improvements to the HAADF method, including a combination of aberration corrected electron optics and low accelerating voltage. The latter is crucial for imaging biological objects, as it allows to reduce damage by the beam and increase the image contrast for light atoms.
Gas flows through the annular opening and atomizes liquid that is sprayed onto the plunger or swirled in from the top. Wetted-throat venturis with round throats (Figures 2 and 3) can handle inlet flows as large as 88,000 m3/h (40,000 cfm) (Brady and Legatski 1977). At inlet flow rates greater than this, achieving uniform liquid distribution is difficult, unless additional weirs or baffles are used. To handle large inlet flows, scrubbers designed with long, narrow, rectangular throats (Figure 4) have been used.
This structure has almost the dimensions of Plato's capital of Atlantis and is covered with hundreds of large and small prehistoric ruins of different types. These ruins were made out of rocks coloured red, white and black. Hübner also shows possible harbour remains, an unusually geomorphological structure, which applies to Plato's description of roofed over docks, which were cut into red, white and black bedrock. These 'docks' are located close to the annular geomorphological structure and close to Cape Ghir, which was named Cape Heracles in antiquity.
Dermatan sulfate accumulates abnormally in several of the mucopolysaccharidosis disorders. An excess of dermatan sulfate in the mitral valve is characteristic of myxomatous degeneration of the leaflets leading to redundancy of valve tissue and ultimately, mitral valve prolapse (into the left atrium) and insufficiency. This chronic prolapse occurs mainly in women over the age of 60, and can predispose the patient to mitral annular calcification. Mitral valve insufficiency can lead to eccentric (volume dependent or dilated) hypertrophy and eventually left heart failure if untreated.
As one source describes There are also compound Cornish Engines, which inevitably need extra connections to drive the additional valves linking the cylinders. Andre describes one near Saarbrucken with an additional beam just to work the steam distributing valves. The Cruquius Engine in the Netherlands is complex, being an annular compound, and constructed ‘upside down’, leaving the exhaust valve at floor level with the steam and equilibrium valve on the floor below. Nonetheless it is controlled by the same three arbors in the usual order.
Totality will be visible across the Northwest Territories and Alberta as well as extreme southwestern Saskatchewan in Canada, and will be widely visible in Montana and partially in North Dakota in the United States of America; partiality will be visible throughout the western United States near sunset and in Siberia. This is the last of 41 umbral solar eclipses (annular, total or hybrid) of Solar Saros 126. The first umbral was in 1323 and last will be in 2044. The total duration is 721 years.
A challenge in cancer therapeutics is that the treatments are often toxic, and getting high enough doses to diseased tissue can result in significant damage. To focus ultrasound for chemotherapy and immunotherapy Ferrara combines an annular array and Bruker MRI. Ferrara makes use of nanoparticle encapsulation and ultrasound to achieve high target-to- background imaging. Alongside their work on cancer, the nanoparticles developed by Ferrara and co-workers can be used to image and deliver microRNA treatments for the treatment of damaged heart tissues.
The subcentral siphuncle contains vesicular deposits and a central tube. Otherwise it is like Ovoverina. Umbelloceras is a small breviconic mandaloceratid with a cross section ranging from slightly depressed to slightly compressed (width > height to width < height) and a T-shaped aperture in which the two lateral branches curve toward the venter. Vesperoceras is a medium size, generally straight, breviconic mandaloceratid with a broad annular expansion to the anterior part of the phragmocone followed by a constriction at the base of the body chamber.
The general problem of finding a hexlet for three given mutually tangent spheres A, B and C can be reduced to the annular case using inversion. This geometrical operation always transforms spheres into spheres or into planes, which may be regarded as spheres of infinite radius. A sphere is transformed into a plane if and only if the sphere passes through the center of inversion. An advantage of inversion is that it preserves tangency; if two spheres are tangent before the transformation, they remain so after.
A subluxation of the humeroradial joint is called a "nursemaid's elbow", also known as radial head subluxation. It is generally caused by a sudden pull on the extended pronated forearm, such as by an adult tugging on an uncooperative child or by swinging the child by the arms during play. In radial head subluxation, there is little complaint of pain, and the person generally reports pain in the proximal forearm. The mechanism is slippage of the head of the radius under the annular ligament.
The BMW 801 radials were air-cooled and the DB 603 and Jumo 213 used an annular radiator, all housed as unitized Kraftei (power-egg) engine "modules" onto an airframe for ease of installation and field maintenance, so the normal under-wing radiators were removed. None were ever built, as Me 410 production was canceled before the engines matured. The Me 410D was a simpler upgrade to the B-series to improve altitude performance, but not to the same degree as the C-series.
Binyamin Har-Even, "Khirbet el-Jafir (West) – A Rural Settlement of the Second Temple Period in the El-Jib Highland", in: Summaries (Part One): Bible, History and Archaeology, pp. 27 - 28 In a 2017 paper, Colin Humphreys and Graeme Waddington suggested that the biblical story of the Israelites' victory against the Amorites over Gibeon, where God made the sun stand still (), may be identified with an annular eclipse which occurred on 30 October 1207 BC."Solar eclipse of 1207 BC helps to date pharaohs", OUP.
Severe Tropical Cyclone Jasmine was a long–lived annular tropical cyclone that affected several countries, particularly Vanuatu and Tonga, over a 19-day span. The sixth cyclone of the season, Cyclone Jasmine developed from an area of disturbed weather on 1 February in the Gulf of Carpentaria. Initially, the storm moved towards the east and across the Cape York Peninsula. Dry air and wind shear prevented the system from strengthening significantly, but a moisture field over the Australian continent helped the storm maintain its intensity.
Several holes have been drilled in ice using direct air circulation, in which compressed air is pumped down the drillpipe, to escape through holes in the drillbit, and return up the annular space between the drillbit and the borehole, carrying the cuttings with it. The technique was first tried by the 1st Soviet Antarctic Expedition, in October 1956. There were problems with poor cuttings removal, and ice forming in the borehole, but the drill succeeded in reaching a depth of 86.5 m.Talalay (2016), p. 71.
In humans, the pupil is round, but its shape varies between species; some cats, reptiles, and foxes have vertical slit pupils, goats have horizontally oriented pupils, and some catfish have annular types. In optical terms, the anatomical pupil is the eye's aperture and the iris is the aperture stop. The image of the pupil as seen from outside the eye is the entrance pupil, which does not exactly correspond to the location and size of the physical pupil because it is magnified by the cornea.
In 1860, he was sent on the Labrador Eclipse Expedition, a United States government mission with a group of fellow astronomers to Labrador to observe the annular eclipse of the sun.. Smith was the author of several text books, including An Elementary Treatise on Mechanics, Embracing the Theory of Statics and Dynamics, and Its Application to Solids and Fluids. He died at Annapolis, on March 26, 1866. One of his daughters, Helen Fairchild Smith, was the head of Wells College from 1894 to 1905..
Moreover, for the foundry "7nm" node, the minimum metal pitch for horizontal lines is taken to be around 40 nm, for which quasar-like illumination is expected, while the minimum metal pitch for vertical lines can be taken to be around 50 nm, for which conventional or annular illumination is preferred. For the quasar illumination, the best focus position varies strongly as a function of pitch, particularly 36-40 nm vs. 48-60 nm, as well as over the 48-72 nm range.V. Phiipsen et al.
In theory the machine could sew about 50 feet of seam in an hour, but in practice about 10 or more feet was the average. The sheets of Alclad used were eight to nine thousandths of an inch thick. As the each section of the hull grew internal annular rings were added at appropriate distances to give stiffness and reinforcement to the hull skin. In addition, lightweight longitudinal channels were added between the circular rings, giving the internal structure the appearance of a huge bird cage.
It has been known for several decades that disc herniations result in a massive inflammation of the associated nerve root. In the past five years increasing evidence has pointed to a specific inflammatory mediator of this pain. This inflammatory molecule, called tumor necrosis factor-alpha (TNF), is released not only by the herniated or protruding disc, but also in cases of disc tear (annular tear), by facet joints, and in spinal stenosis. In addition to causing pain and inflammation, TNF may also contribute to disc degeneration.
Unlike most other tropical cyclones, Sergio did not possess an inner wind core. Instead, the maximum sustained winds were located in a rainband approximately 125 mi (205 km) east of the center. alt=Category 3 Hurricane Sergio acquiring some annular characteristics on October 7 Despite being located within a favorable environment of warm sea surface temperatures and low wind shear, Sergio only gradually intensified over the next couple of days, the system becoming a Category 1 hurricane on October 2 at 00:00 UTC.
The forewings are pale yellow and thinly scaled, the costa shaded (darkest at the base). There is a fuscous basal spot on the costa and a subbasal spot in the cell, as well as an antemedial, wavy, oblique, fuscous line, followed by a small annular spot in the cell. The submedian is brownish and a short line is found medially below it to the antemedial. There are two dark lines at the end of the cell, connected with the postmedial by a single line.
The deeper the well, the more overburden pressure, which means the greater the annular compressive stress conditions. On the rocks lying at depths of 3–5 km the compressive stresses may reach up-to 75–125 MPa. In the near-well zone, as a result of concentration these stresses increase and sometimes become equal to double 150–250 MPa. If the tectonic stresses is several times higher than stresses from the weight of rocks, the stresses in the near-well zone may be even greater.
A Continuous Oscillatory Baffled Reactor (COBR) is a specially designed chemical reactor to achieve plug flow under laminar flow conditions. Achieving plug flow has previously been limited to either a large number of continuous stir tank reactors (CSTR) in series or conditions with high turbulent flow. The technology incorporates annular baffles to a tubular reactor framework to create eddies when liquid is pushed up through the tube. Likewise, when liquid is on a downstroke through the tube, eddies are created on the other side of the baffles.
After considerable experimentation, Denys Bliss at Hovercraft Development Ltd. found the solution to this problem. Instead of using two separate rubber sheets to form the skirt, a single sheet of rubber was bent into a U shape to provide both sides, with slots cut into the bottom of the U forming the annular vent. When deforming pressure was applied to the outside of this design, air pressure in the rest of the skirt forced the inner wall to move in as well, keeping the channel open.
Glabrous, much-branched, perennial herb, arising from branched, annular, tuberous rootstock up to 2 cm thick, with crown surrounded by fibrous, remnant, sheathing bases of petioles. Height 30–100 cm. Basal leaves numerous, petioles flattened with ovate sheaths, 2 - 6.5 cm in length; leaf-blades oblong-ovate to broad-ovate, up to 35 x 18 cm (usually smaller), bi- to tripinnatifid, pinnae 3 - 4 pairs, petiolulate, terminal lobes lanceolate, 3-lobed at apex. Upper leaves simplified with sheathing petioles, reduced upwards, often absent, leading to aphyllous branching.
Extinct terrestrial vascular plants of the Silurian to Devonian periods. Stem of the order of several mm to several cm in diameter and several cm to several metres long, erect or arched, dichotomizing occasionally, furnished with true roots at the base. Vascular bundle an exarch actinostele, tracheids of primitive annular or helical type (so-called G-type). Stem clothed in either microphylls (leaves with a single vascular thread or 'vein'), or with leaf-like enations (unvascularized projections) with a vascular trace into the base of each enation.
The typhoon took on annular characteristics, with a symmetric ring of deep convection surrounding a 30 km (15 mi) well-defined eye and fairly uniform cloud top temperatures. Environmental conditions were favorable with radial outflow, enhanced by a poleward outflow channel into the TUTT and a subtropical jet to the east-northeast. Noru's previous southward motion also led itself to the warmer area with SSTs at 29 °C to 30 °C, favoring intensification. At this time, Noru began to drift westward within a competing steering environment.
It is a generalist species that can parasitise a wide range of fish species, including the shortnose greeneye (Chlorophthalmus agassizi), lesser weever fish (Echiichthys vipera), red porgy (Pagrus pagrus), comber (Serranus cabrilla), painted comber (Serranus scriba), Brown comber (Serranus hepatus), Annular seabream (Diplodus annularis), and the common two- banded sea bream (Diplodus vulgaris). Ceratothoa steindachneri has also been reported on Raja asterias, R. polystigma, and R. albas. However, these records are to be confirmed as they are most likely the result of trawl transfers.
Bruno Ernst cites M. C. Escher as stating that he began Print Gallery "from the idea that it must be possible to make an annular bulge, a cyclic expansion ... without beginning or end."Ernst, Bruno. De toverspiegel van M. C. Escher, Meulenhoff, Amsterdam, 1976; English translation by John E. Brigham: The Magic Mirror of M. C. Escher, Ballantine Books, New York, 1976 Escher attempted to do this with straight lines, but intuitively switched to using curved lines which make the grid expand greatly as it rotates.
Cut through a Vello tube - blue: mandrel with blown air connection, orange: liquid glass and drawing direction In the Vello process, the glass runs through an annular slot from the bottom of the feeder. This slot is formed between the round outlet nozzle of the feeder and a height-adjustable hollow needle (also a mandrel). Here, the tube is "inflated" with compressed air as well. The glass tube which initially emerges in the vertical direction is then deflected into the horizontal position in the free sag.
The annular air intake surrounded a reduction gear for propeller drive takeoff, and the exhaust duct was also annular.Green, W. and Swanborough, G.; "Plane Facts", Air Enthusiast Vol. 1 No. 1 (1971), Page 53. With predicted output of 1,000 bhp at 13,500 rpm the Cs-1 stirred interest in the Hungarian aircraft industry with its potential to power a modern generation of high-performance aircraft, and construction was begun of a twin- engined fighter-bomber, the Varga RMI-1 X/H, to be powered by it.
The Baily's beads effect or diamond ring effect is a feature of total and annular solar eclipses. As the Moon covers the Sun during a solar eclipse, the rugged topography of the lunar limb allows beads of sunlight to shine through in some places while not in others. The effect is named after Francis Baily, who explained the phenomenon in 1836. The diamond ring effect is seen when only one bead is left, appearing as a shining "diamond" set in a bright ring around the lunar silhouette.
This distance increases with frequency. As a result, any station employing DX will be surrounded by an annular dead zone where they can't hear other stations or be heard by them. This is the phenomenon that allows short wave radio reception to occur beyond the limits of line of sight. It is utilized by amateur radio enthusiasts (hams), shortwave broadcast stations (such as BBC and Voice of America) and others, and is what allows one to hear AM (MW) stations from areas far from their location.
It was first teased by executive producer Richard Jasek in January 2013. The episode saw several storylines play out with Kyle Canning (Chris Milligan) sustaining serious damage to his eyesight, a child kidnapping, the introduction of a new family and the return of two past characters; Mark Brennan (Scott McGregor) and Brad Willis (Kip Gamblin). Two promotional trailers for the episode were released by Eleven and British broadcaster Channel 5 respectively. A real annular eclipse occurred in Australia ten days before the episode was broadcast.
New York / London. pp. 13-20, 63. Urban development in the early Middle Ages, characteristically focused on a fortress, a fortified abbey, or a (sometimes abandoned) Roman nucleus, occurred "like the annular rings of a tree",Siegfried Giedion, Space, Time and Architecture (1941) 1962, in reference to an air view (fig.8) of the medieval Italian town of Bagnocavallo. Giedion's source was Luigi Piccinati, "Urbanistica Medioevale" in Urbanistica deal Antichità ad Oggi (Florence 1943). whether in an extended village or the centre of a larger city.
Annular eclipse of the Sun by Phobos as viewed by the Mars Curiosity rover (20 August 2013). transits the Sun, as viewed by the Mars Opportunity rover (10 March 2004). A transit of Phobos across the Sun as seen from Mars takes place when Phobos passes directly between the Sun and a point on the surface of Mars, obscuring a large part of the Sun's disc for an observer on Mars. During a transit, Phobos can be seen from Mars as a large black disc rapidly moving across the face of the Sun.
A heavy-duty magnetic drilling machine manufactured by BDS Maschinen GmbH (Germany) drilling 100mm-thick mild steel. A magnetic drill is a portable machine for drilling holes in large and heavy workpieces which are difficult to move or bring to a stationary conventional drilling machine. It has a magnetic base and drills holes with the help of cutting tools like annular cutters (broach cutters) or with twist drill bits. There are various types depending on their operations and specializations, like magnetic drilling cum tapping machines, cordless, pneumatic, compact horizontal, automatic feed, cross table base etc.
Blow extrusion of plastic film The manufacture of plastic film for products such as shopping bags and continuous sheeting is achieved using a blown film line. Polymer melt from an extruder is fed through an upright die with an annular opening. There are several types of dies that can be used, depending on final requirements of film quality and characteristics of the polymer melt: spider, crosshead, and spiral dies. A spider die consists of an internal mandrel connected to the outer die wall by several "legs", and is a moderately complex design.
The first dye type is an annular, or tubing/jacketing, die that extrudes a tube of polymer that is initially not touching the bare wire. A vacuum is then applied to the still-molten polymer tube, causing it to be drawn onto and bond to the surface of the bare wire. This type of die is typically used to coat very thin wires with polymer jacketing that is highly viscous. The second die type, known as a pressure type die, relies on contact between the jacketing polymer and bare wire inside the die.
Moreover, winters will usually be wetter than normal in the south and southwest with more snowfall in the alpine areas, but drier in the east coast due to less moist onshore flows from the east. This phase will usually be more frequent with an El Niño event. Winds associated with the Southern Annular Mode cause oceanic upwelling of warm circumpolar deep water along the Antarctic continental shelf, which has been linked to ice shelf basal melt, representing a possible wind-driven mechanism that could destabilize large portions of the Antarctic ice sheet.
This motion is further enhanced by a pronounced three-dimensional configuration during systole, the characteristic saddle shape. These changes throughout the cycle are believed to be key to optimize leaflet coaptation and to minimize tissue stresses. The challenge of mitral valve annuloplasty is to improve the diseased and distorted shape of the mitral valve and to reestablish the physiological configuration, while preserving normal annular dynamics. Today, cardiac surgeons can select from a variety of annuloplasty devices, flexible, semi-rigid, or rigid, incomplete or complete, planar or saddle-shaped, adjustable and non-adjustable.
In August 1912, the G.E.2 was flown by England in the Military Aeroplane Trials at Larkhill. England left the Bristol company, and in 1912 in association with James Radley produced the Radley-England waterplane; it was the first three-engined aircraft built in the United Kingdom. England also built and tested the Lee-Richards Annular Wing Monoplane. Between 1913 and 1916, he was a test pilot and consultant engineer to a number of aircraft constructors, mainly on the English south coast, including J. Samuel White and Company and White and Thompson.
Close-up view of a flat Fresnel lens shows concentric circles on the surface The Fresnel lens reduces the amount of material required compared to a conventional lens by dividing the lens into a set of concentric annular sections. An ideal Fresnel lens would have an infinite number of sections. In each section, the overall thickness is decreased compared to an equivalent simple lens. This effectively divides the continuous surface of a standard lens into a set of surfaces of the same curvature, with stepwise discontinuities between them.
He seems to have recognised the communication of the convoluted surface of the brain and that between the lateral cavities beneath the fornix. He described the corpora striata and optic thalami; the four orbicular eminences, with the bridge, which he first named annular protuberance; and the white mammillary eminences, behind the infundibulum. In the cerebellum he remarks the arborescent arrangement of the white and grey matter and gives a good account of the internal carotids and the communications which they make with the branches of the basilar artery. Willis replaced Nemesius's doctrine.
Pancake G–M tube, the circular concentric anode can clearly be seen. The pancake tube is a variant of the end window tube, but which is designed for use for beta and gamma contamination monitoring. It has roughly the same sensitivity to particles as the end window type, but has a flat annular shape so the largest window area can be utilised with a minimum of gas space. Like the cylindrical end window tube, mica is a commonly used window material due to its low mass per unit area.
Since 1994 according Baranov Central Institute of Aviation Motor Development specification KBKhA has been developed experimental axial symmetrical scramjet 58L (the lead designers — Y.V. Liplavy, Y.A. Martynenko), for studying of processes of hydrogen combustion at stream velocities 3-6.5 M and altitudes of 20–35 km flight conditions. The liquid hydrogen is an engine fuel passing CC cooling channels and being introduced into the combustion zones. The combustion chamber is an annular and three-zone design. In the first zone the hydrogen combustion takes place in subsonic airflow, in two others — in supersonic flow.
The variable-density wind tunnel had a closed-circuit design with an annular return flow to minimize the volume of the tank. A fan powered by a 250-hp motor could produce an air speed up to . A sectional drawing of original, close-throat test section (top), and the failed, post-fire, open-throat test section from 1927 (bottom). During a fire in 1927, the internal wooden test section of the VDT was destroyed and was rebuilt with an open-throat design before complications required it be rebuilt again with a closed-throat design.
This annular solar eclipse was large because the Moon covered 99.4% of the Sun, with a path width of only 25 km (15.534 mi, or 82,080.997 feet). It was visible in Australia, crossing over Tasmania and southern Stewart Island of New Zealand near sunrise on February 5th (Thursday), and ended at sunset over western South America on February 4th (Wednesday). Occurring only 4 days before perigee (Perigee on February 8, 1981), the moon's apparent diameter was larger. The moon's apparent diameter was 7 arcseconds smaller than the July 31, 1981 total solar eclipse.
Production started in 1992 with the thrust FJ44-1A, which comprises a diameter single stage blisk fan plus a single intermediate pressure (IP) booster stage, driven by a 2 stage low pressure (LP) turbine, supercharging a single stage centrifugal high pressure (HP) compressor, driven by a single stage uncooled high pressure (HP) turbine. The combustor is an impingement cooled annular design. Fuel is delivered to the combustor through an unusual rotating fuel nozzle system, rather than the standard fuel-air mixers or vapourisers. The bypass duct runs the full length the engine.
The Coléoptère featured a central core akin to the Atar Volant, but differed in that the fuselage was surrounded by an annular wing greatly resembling the proposals made by von Zborowski. Aerodynamic control and stability was regulated by a series of four triangular winglets, which were installed upon the outwards side of the annual wing; however, these were only effective during conventional horizontal flight. Instead, control while hovering was provided by a series of deflecting vanes within the engine exhaust. The undercarriage of the Coléoptère consisted of four relatively compact castored wheels.
The design comprises five main features. It has a three-stage low pressure compressor, five stage high pressure chamber, an annular combustion chamber and a single stage high and low pressure turbines. In August 2005, the Russian export organization known as Rosoboronexport and India's Hindustan Aeronautics Limited (HAL) signed an agreement for the licensed production of up to 1,000 AL-55I engines. The agreement includes a firm order for 250 engines to be manufactured at HAL facilities in India, to power both HAL HJT-36 trainer and HAL HJT 39 combat trainer aircraft.
Opportunity, March 2004) Due to the small size of Phobos (about ) and its rapid orbital motion, an observer on the surface of Mars would never experience a solar eclipse for longer than about thirty seconds. Phobos also takes only 7 hours 39 minutes to orbit Mars, while a Martian day is 24 hours 37 minutes long, meaning that Phobos can create two eclipses per Martian day. These are annular eclipses, because Phobos is not quite large enough or close enough to Mars to create a total solar eclipse.
The basic configuration of the PW300 is as follows: single-stage fan, driven by a three-stage low pressure turbine, supercharging a four-stage axial/single-stage centrifugal high-pressure compressor, driven by a two-stage high-pressure turbine. An annular combustor is featured. Some versions have an unmixed exhaust, but the PW306 and PW308 include a forced mixer. A Full Authority Digital Engine Control (FADEC) system is incorporated. The PW307A is a new centre-line engine developed specifically for a tri-jet application on the Dassault Falcon 7X.
To allow this rotation, the proximal (elbow) end of the radius is held in proximity to the ulna by a ligament known as the annular ligament. This is a circular ligamentous structure within which the radius is free, with constraints existing elsewhere in the forearm, to rotate.The proximal end of the radius in young children is conical, with the wider end of the cone nearest the elbow. With the passage of time the shape of this bone changes, becoming more cylindrical but with the proximal end being widened.
Neonatal bowel obstruction is grouped into two general categories: high, or proximal, obstruction and low, or distal obstruction, both of which are suspected by failure to pass meconium at birth. High obstruction can be suspected based on the double bubble sign. Cases without distal gas are usually related to duodenal atresia, while high obstruction with distal gas need an upper gastrointestinal series because of the need to distinguish duodenal web, duodenal stenosis and annular pancreas from midgut volvulus, the latter being a surgical emergency. Confirmation is ultimately by surgical intervention.
The wings are black with red markings. There is a large annular spot at the base of the forewings, from the subcostal to the submedian. There is also a quadrate spot from vein 3 to the costa, filled in with black, which is crossed by the discocellular. A red line runs from the outer costal angle of this spot to the yellow apex, then forming large subterminal lunules between the veins to vein 3, and below it twice angled to the submedian where it joins the basal spot.
Learjet 25 about to take-off Two General Electric CJ610-6 single-rotor axial-flow turbojet engines are pylon-mounted on each side of the aft fuselage. Each engine is rated at 2950 pounds of thrust at sea level. The engine compartments consist of an eight- stage axial-flow compressor directly coupled to a two-stage turbine, a through-flow annular combustion system, variable inlet guide vanes, controlled compressor interstage bleed, exhaust nozzle and accessory drive system. Starting ignition is provided by a dual output capacitor-discharge system.
The Trent 900 is an axial flow, high bypass turbofan with the three coaxial shafts of the Rolls- Royce Trent family. The fan with swept blades is driven by a 5-stage LP turbine, the 8-stage IP compressor and the 6-stage HP compressor are both powered by a single stage turbine, with the HP spool rotating in the opposite direction of the others. It has a single annular combustor and is controlled by an EEC. It is certified for thrusts between 334.29 to 374.09 kN (75,152 to 84,098 lbf).
There were variations made in copper alloy in the fifth and sixth centuries which were mostly likely worn in pairs on the shoulders. The Quoit Brooch Style of the Anglo-Saxon era was named for this elaborate brooch. The brooch "consists of a decorated, flat ring enclosing a penannular ring, secured by a pin that passes through a slit in the penannular ring and is held by knobs. The outer annular ring is characteristically decorated in concentric circles of lightly chip-carved geometric motifs, quadrupeds, sea creatures and human masks".
Two types of dome-type phase plug: one with radial slits and one with concentric ring slits, also called annular or circumferential In horn loudspeakers, the phase plug serves to carry sound waves out from all areas of the compression driver diaphragm through the compression chamber to the horn throat such that each pulse of sound reaches the throat as one coherent wave front. With a successful implementation, high-frequency performance is extended higher. The phase plug is a complex and expensive element of the compression driver. Its manufacture requires fine tolerances.
5./JG 4 was captured during Operation Bodenplatte after its engine had been damaged by American light flak. The Fw 190 A-8 entered production in February 1944, powered either by the standard BMW 801 D-2 or the 801Q (also known as 801TU). The 801Q/TU, with the "T" signifying a Triebwerksanlage unitized powerplant installation specifically for single-engined aircraft, was a standard 801D with improved, thicker armour on the front annular cowling, which also incorporated the oil tank, upgraded from 6 mm (.24 in) on earlier models to 10 mm (.
Inferiorly, a few fibres attached to the neck of the radius support a fold of the synovial membrane without interfering with the movements at the joint. The fibrocartilage on the upper part of the ligament is continuous with the hyaline cartilage of the radial notch. At the posterior attachment the ligament widens to reach above and below the radial notch. A thickened band which extends from the inferior border of the annular ligament below the radial notch to the neck of the radius is known as the quadrate ligament.
The cap margins of young specimens are usually curved inwards, and have irregular, wavy edges; young specimens may also have fragments of the partial veil hanging off the margin. The whitish partial veil is similar to those of the genus Cortinarius—cobwebby, and made of silky fibrils. When the cap expands and the veil rips, the fibrils remains briefly as an annular zone on the stem, before fading into nothing. The gills have an adnate or adnexed attachment to the stem, which later becomes seceding (pulled away from the stem).
Generally, the swage nut is made of a hard metal such as stainless steel, which is inserted into a pre- drilled hole in a softer ductile material such as aluminum. The inserted shank has three diameters: a main shaft which fits the hole closely, a thin smaller- diameter undercut, and a larger-diameter serrated clinching ring. Forcing the clinching ring into softer material, with an arbor press or by tightening a screw through the hole, causes it to plastically deform (swage) into the annular recess in the shank. This locks the nut into the hole.
Original contributions have been made by Wang to understand the inelastic scattering in electron diffraction and imaging. His textbook on Elastic and Inelastic Scattering in Electron Diffraction and Imaging (Plenum Press, 1995) is regarded as "a noteworthy achievement and a valuable contribution to the literature" (American Scientist, 1996). In scanning transmission electron microscopy (STEM), the high-angle annular dark-field (HAADF) (referred as Z-contrast) is dominated by the thermal diffuse scattering (TDS), which is revealed by Wang. And the dynamic theory for including TDS in image simulation of HAADF was first proposed by Wang.
They were erect or arched, dichotomized (forked) occasionally, and had adventitious roots arising directly from prostrate stems. As in Asteroxylon the vascular bundle in the stems was an exarch actinostele, with a star-shaped arrangement of tracheids of a primitive annular or helical type (so-called G-type). Leaves were unbranched strap-shaped microphylls (4 cm long in B. longifolia) with a single prominent vascular thread, arranged spirally on the stem. The sporangia were borne in the axils of the leaves, broader than long, dehiscing by a transversely-orientated slit.
A subluxation of a joint is where a connecting bone is partially out of the joint.Page 107 in: In contrast to a luxation, which is a complete separation of the joints, a subluxation often returns to its normal position without additional help from a health professional.page 63 in: An example of a joint subluxation is a nursemaid's elbow, which is the subluxation of the head of the radius from the annular ligament. Other joints that are prone to subluxations are the shoulders, fingers, kneecaps, ribs, wrists, ankles, and hips affected by hip dysplasia.
The secondary walls have thickenings in various forms—as annular rings; as continuous helices (called helical or spiral); as a network (called reticulate); as transverse nets (called scalariform); or, as extensive thickenings except in the region of pits (called pitted). Tracheids provide most of the structural support in softwoods, where they are the major cell type. Because tracheids have a much higher surface to volume ratio compared to vessel elements, they serve to hold water against gravity (by adhesion) when transpiration is not occurring. This is likely one mechanism that helps plants prevent air embolisms.
Severe Tropical Cyclone Jasmine (RSMC Nadi designation: 12F, JTWC designation: 10P) was a powerful and long-lived annular tropical cyclone that affected several countries, particularly Vanuatu and Tonga, over a 16-day span in February 2012. The system was the second cyclone and the only severe tropical cyclone of the relatively quiet 2011–12 South Pacific cyclone season. Cyclone Jasmine developed from an area of disturbed weather on 1 February in the Gulf of Carpentaria. Initially, the storm moved towards the east and across the Cape York Peninsula.
As it moved across the South Pacific, earlier existing wind shear conditions lessened, and Jasmine began to strengthen at a faster rate. Steadily intensifying, Jasmine reached peak intensity on 8 February as a Category 4 equivalent on the Saffir–Simpson Hurricane Scale, while beginning to show annular characteristics. The next day Jasmine entered an area of vertical wind shear, which consequently weakened the cyclone and caused its eye to expand. A high-pressure area south of Jasmine later steered the weakening cyclone to the northeast on 12 February.
Shapley 1 (Sp 1 or PLN 329+2.1) is an annular planetary nebula in the constellation of Norma with a magnitude of +12.6. As viewed from Earth, it is peculiar in that it seems to be a non-bipolar, torus-shaped planetary nebula. However, it is thought that this is due to the viewpoint of looking directly down on a binary system whose orbit is perpendicular to Earth. Discovered in 1936 by Harlow Shapley, it is approximately 4900 light years from Earth, and is around 8700 years old.
A partial eclipse was seen from the much broader path of the Moon's penumbra, including all of Europe, Africa and southwestern Asia. The Sun was 96% covered in a moderate annular eclipse, lasting 4 minutes and 32 seconds and covering a broad path up to 162 km wide. The next solar eclipse in Africa occurred just 6 months later. It was the 43rd eclipse of the 134th Saros cycle, which began with a partial eclipse on June 22, 1248 and will conclude with a partial eclipse on August 6, 2510.
It had a magnitude of 1.0394 that was visible from a narrow corridor through northern Canada (Nunavut), Greenland, central Russia, eastern Kazakhstan, western Mongolia and China. Occurring north of the arctic circle, it belonged to the so-called midnight sun eclipses. The largest city in the path of the eclipse was Novosibirsk in Russia. The moon's apparent diameter was 1 arcminute, 17.8 arcseconds (77.8 arcseconds) larger than the February 7, 2008 annular solar eclipse. This was the first eclipse this season, with the second being the 16 August 2008 partial lunar eclipse.
Early on May 7, Noul entered the Philippine Area of Responsibility and was assigned the name Dodong by PAGASA. Later that day, the JTWC upgraded Noul to a Category 3 typhoon as a small eye had developed. At the same time, according to Jeff Masters of Weather Underground, Noul had taken on annular characteristics. On May 10, the JTWC further upgraded Noul to a Category 5 super typhoon, and the JMA assessed Noul with 10-minute sustained winds of 205 km/h (125 mph) and a minimum pressure of 920 mbar, its peak intensity.
The temperature was held around , sufficient to physically vapourise the oil, but not to break it down chemically. This fractional distillation supported the use of heavy oil fuels, the unusable tars and asphalts separating out in the vapouriser. Hot-bulb ignition was used, which Griffin termed the "catathermic igniter", a small isolated cavity connected to the combustion chamber. The spray injector had an adjustable inner nozzle for the air supply, surrounded by an annular casing for the oil, both oil and air entering at pressure, and being regulated by a governor.
The STEM rasters a focused incident probe across a specimen that (as with the TEM) has been thinned to facilitate detection of electrons scattered through the specimen. The high resolution of the TEM is thus possible in STEM. The focusing action (and aberrations) occur before the electrons hit the specimen in the STEM, but afterward in the TEM. The STEMs use of SEM-like beam rastering simplifies annular dark-field imaging, and other analytical techniques, but also means that image data is acquired in serial rather than in parallel fashion.
Since ancient times, when there were the first coal mines, it was observed, that increasing the depth of the development the coal tunnel, under the action of overburden pressure, surrounding rocks become harder and little-permeable. To solve this problem they developed a cavern of a certain form in the rock. More modern mining geo- mechanics explain the reason for the occurrence of this effect in relation to drilling wells. During any drilling process in the well there is formed the annular compressive stress conditions around the wellbore zone.
The JT15D was, when it first ran in 1967, rare among turbofan engines in that it uses a centrifugal compressor as its high-pressure stage.Gunston 1989, p.131. About 70% of the air passing through the fan goes down the bypass duct. The JT15D-4 and later variants use a "booster" axial stage behind the fan which runs at the same speed as the fan and directs the remaining 30% of the air into the high pressure compressor, after which it passes into a reverse-flow annular combustor.
Map of Niuafoou, showing Lake Vai Lahi Vai Lahi (Tongan: Big water) is the central crater lake of the Tongan island of Niuafoou. The island is the most northerly island of Tonga, is the most northerly island in the kingdom of Tonga, and is located some 570 km north of the kingdom's main island, Tongatapu. Niuafoou is annular in shape, the rim of an active volcano. The island ring encloses two large lakes, Vai Lahi and the much smaller Vai Sii (also known as Vai Mataaho), plus some eight much smaller ponds.
C-reactive protein (CRP) is an annular (ring-shaped), pentameric protein found in blood plasma, whose circulating concentrations rise in response to inflammation. It is an acute-phase protein of hepatic origin that increases following interleukin-6 secretion by macrophages and T cells. Its physiological role is to bind to lysophosphatidylcholine expressed on the surface of dead or dying cells (and some types of bacteria) in order to activate the complement system via C1q. CRP is synthesized by the liver in response to factors released by macrophages and fat cells (adipocytes).
RSMC La Reunion commenced advisories on Tropical Disturbance 04 on November 14, raising the status to a Tropical Depression later the same day. At the time of formation, it was some south of Diego Garcia. Throughout that day, and into the 15th, Anja rapidly intensified from a severe tropical storm to a tropical cyclone on the MFR scale and a Category 3-equivalent cyclone on the Saffir-Simpson Hurricane Scale (SSHS), while remaining well away from land. The system displayed annular characteristics and was very small; its diameter was and it displayed a pinhole eye.
There is one prominent planetary nebula in Andromeda: NGC 7662 (Caldwell 22). Lying approximately three degrees southwest of Iota Andromedae at a distance of about 4,000 light-years from Earth, the "Blue Snowball Nebula" is a popular target for amateur astronomers. It earned its popular name because it appears as a faint, round, blue-green object in a telescope, with an overall magnitude of 9.2. Upon further magnification, it is visible as a slightly elliptical annular disk that gets darker towards the center, with a magnitude 13.2 central star.
A major area of research in the early years of fusion energy research was the magnetic mirror. Most early mirror devices attempted to confine plasma near the focus of a non- planar magnetic field generated in a solenoid with the field strength increased at either end of the tube. In order to escape the confinement area, nuclei had to enter a small annular area near each magnet. It was known that nuclei would escape through this area, but by adding and heating fuel continually it was felt this could be overcome.
Another innovative feature of the steam bogie assembly was the ability to interchange them when faults occurred, an easy operation for maintenance staff when compared to the complexities of overhauling a regular steam locomotive's motion. The three cylinders of each bogie were cast in mono-block format, each surrounded by two annular inlet steam chests and a single large outlet steam chest. These had the added function of keeping the cylinder heated by hot steam to maintain the temperature and pressure of steam entering the cylinders. However, these castings were difficult to machine accurately.
Several of the "non-flying" types flew with the help of "movie magic". The Lee Richards Annular Biplane with circular wings (built by Denton Partners on Woodley Aerodrome, near Reading) was "flown on wires" during the filming.Wheeler (1965), pp. 92-93 The flying replicas were specifically chosen to be different enough that an ordinary audience member could distinguish them. They were all types reputed to have flown well, in or about 1910. In most cases this worked well, but there were a few surprises, adding to an accurate historical reassessment of the aircraft concerned.
It is typically associated with abnormal embryological development, however adult cases can develop. It can result from growth of a bifid ventral pancreatic bud around the duodenum, where the parts of the bifid ventral bud fuse with the dorsal bud, forming a pancreatic ring. It can also result if the ventral pancreatic bud fails to fully rotate, so it remains on the right or if the dorsal bud rotates in the wrong direction, such that the duodenum is surrounded by pancreatic tissue. Blockage of the duodenum develops if inflammation (pancreatitis) develops in the annular pancreas.
This impact feature is not exposed at the surface, but it is known only through wells drilled for oil and gas. First reported by Donald Stone, Cloud Creek is a circular structure documented using several 2D reflection seismic lines of fair to good quality, gravity, magnetic and borehole data. The structure has a central core of brecciated, fractured and faulted rocks uplifted up to 520 m relative to the normal stratigraphy outside the structure. The core is surrounded by an annular trough and a detached fault-bounded rim anticline.
He did his doctoral work with John Yamanis on reactions engineering with annular bed reactors. His academic career started as an Assistant Professor at Virginia Polytechnic Institute & State University in 1981 and rose until becoming the Charles O. Gordon Professor of Chemical engineering in 1990. During his time at Virginia Tech, he developed some of the earlier Zeolite molecular sieves and increasing the pore size. In 1991, he joined the faculty of the California Institute of Technology and served as the Executive Officer of the department from 1999 to 2004.
Fire damper deficiency: The installed annular clearance around the damper violates the certification listing The damper's certification listing is violated because the damper shares the opening with other through-penetrants and the drywall fire- separation is not continuous. In the US, the Joint Commission, State Fire Marshals and Other Authorities Having Jurisdiction (AHJ's), require some Fire and Smoke Dampers to be tested at specified intervals. Similarly, European authorities mandate maintenance and repairs of fire dampers also, as part of approvals or listings issued following successful testing of fire damper assemblies.
Figure (8) showing Coriolis meter Flow conditioners make no effect on meter accuracy while using wet gas due to the annular flow regime, which is not highly affected by flow conditioners. In single-phase conditions, Coriolis meter gives accurate measurement even in presence of severe flow disturbances. There is no need for flow conditioning before the meter to obtain accurate readings from it, which would be the case in other metering technologies like orifice and turbine. On the other hand, in two-phase flows, the meter consistently gives negative errors.
Amid favorable conditions, Noru rapidly intensified into the season's first super typhoon, and reached peak intensity with annular characteristics on July 31. In early August, Noru underwent a gradual weakening trend while curving northwestwards and then northwards. After stalling off the Satsunan Islands weakening to a severe tropical storm again on August 5, the system began to accelerate northeastwards towards the Kansai region of Japan, making landfall in Wakayama Prefecture on August 7. Noru became extratropical over the Sea of Japan on August 8, and dissipated one day later.
As it falls, it leaves a thread attached by the meniscus to the nozzle as long as the viscosity is in the correct range for fiber formation. The smaller the annular ring of the nozzle and the thinner the wall at exit, the faster the drop will form and fall away, and the lower its tendency to wet the vertical part of the nozzle. The surface tension of the glass is what influences the formation of the meniscus. For E-glass it should be around 400 mN/m.
Annular Seal (RTJ Seal) is a high integrity, high temperature, high pressure seal for applications in the oil industry, oilfield drilling, pressure vessel connections, pipes, valves and more. The movement of the ring packing (RTJ) can be described as an irregular flow in the groove of the deformed sealing flange due to the axial compressive load. Colored seal (RTJ seal) has a small load area, which leads to a large surface pressure between the sealing surface and the groove, the maintenance properties are poor and not suitable for reuse.
Across the street is a modern residential development; on the west the church property is bounded by the trailway along the route of the Old Croton Aqueduct, a linear National Historic Landmark. A driveway leads into the property from North Broadway, opening into a large annular parking area just northeast of the main church building, where it meets a walkway from a lych gate along Broadway. The parish house extends from its north side, to the west of the parking area. A modern garage is attached to its west.
Additionally, her work demonstrated links between large- scale atmospheric phenomena (e.g. Southern Annular Mode and El Niño Southern Oscillation) and local phytoplankton dynamics. Schloss plays a central role in the development of international collaborations in Antarctic research. She has been successful in working in polar science in different countries, such as Argentina, Canada, and Germany through the promotion and participation in numerous international research projects and initiatives, cooperating with researchers from USA, Spain, Belgium, Brazil, Poland, and the UK. She further participates in the development of the Antarctic Environmental Portal.
The Floatwall annular combustor ensures the clean burning of the fuel and reduced NOx generation. The high-pressure turbine blades are made of single-crystal superalloys and impingement cooled using air from the high-pressure compressor. The two spools are counter-rotating, which results in weight savings due to the elimination of a row of stators. The requirement for the ATF to supercruise, or fly supersonic without afterburners, results in a very low bypass ratio of 0.3 for the F119-PW-100 in order to achieve high specific thrust.
Epsilon persisted into December, extending the 2005 season beyond its stated November 30 end date. On December 1, it began a northeast motion due to an approaching trough, and the next day it attained hurricane status. After turning to the east, it developed characteristics of an annular hurricane, meaning it had a circular eye, a ring of convection, and had few fluctuations in its intensity. On December 5 Epsilon attained peak winds of 85 mph (140 km/h), and the next day it turned to the south and southwest.
The oxygen injector was a fixed tuyere, located at corner of the base with the side wall, with an annular nitrogen shroud. The initial pilot plant tests showed that it was difficult to maintain the protective accretion that had been generated in the small-scale tests, due to the variation in temperature and bullion composition that occurred throughout the cupelling cycle. Without the accretion, the nitrogen shroud could not provide sufficient protection to the injector, and it burned back to the level of the refractory lining, which resulted in damage to the lining.
The gasholder piston moves up and down the inside of the shell as gas enters and exits the gasholder. The weight of the piston (less the weight of the level weights) produces the pressure at which the gasholder will operate. The piston is designed to apply an equally distributed weight to ensure that the piston remains level at all times. The piston made up of the following sub-elements: ; Piston deck : The outer annular area is formed from butt welded steel plates resting on steel section rest blocks.
The structures have been dated by uranium series dating as 176.5 (±2.1) thousand years old, with 2σ uncertainties (95.5% probability). There are two annular structures, one 6.7 by 4.5 metres, and the other 2.2 by 2.1 metres, composed of one to four aligned layers of stalagmites, with some small pieces placed inside the layers to support them. Some stalagmites were placed vertically against the rings, possibly as reinforcement. There are also four stacks of stalagmites between 0.55 and 2.60 metres in diameter, two of which were inside the large ring and two outside it.
Mk I A Heavy Cockatrice The PWD brought together and supervised a number of otherwise independent developments of vehicle mounted flamethrowers. The first product of this work was a prototype of Cockatrice that was demonstrated in August 1940. Reginald Fraser of Imperial College, London University, who was also a director of the Lagonda car company, developed an annular flamethrower, that threw petrol with an outer layer of thickened fuel. He thought that this would reduce the risk of fire working backwards to the fuel tank because oxygen would not be present.
In about 10% of adults, an accessory pancreatic duct may be present if the main duct of the dorsal bud of the pancreas does not regress; this duct opens into the minor duodenal papilla. If the two buds themselves, each having a duct, do not fuse, a pancreas may exist with two separate ducts, a condition known as a pancreas divisum. This condition has no physiologic consequence. If the ventral bud does not fully rotate, an annular pancreas may exist, where part or all of the duodenum is encircled by the pancreas.
Finger rings are worn in the early Anglo-Saxon era, but declined in popularity in the seventh and eighth centuries, and became fashionable again in the ninth century. At the end of the seventh century, circular brooches increased in popularity over long brooches, and annular and disc brooches start appearing in grave-goods. Eighth century circular brooches are rarely found, but many examples have been found from the ninth to eleventh centuries. Anglo-Saxon rings, 7th to 11th century Brooches which resemble modern safety pins appear in the seventh century.
Located in the east part of the mountain, the Maitreya Garden was built in 2000 with Japanese Corporate Myokoen as a China- Japan Friendship Garden. The garden covers 30 thousand square meters, including the Maitreya statue, Sakura garden, and some other affiliated structures, which is a blend of Chinese and Japanese styles of garden architecture. The whole statue has a height of 30 meters, thus it is known as "the number one largest Buddha north of Yangze River." The information about Maitreya is carved behind the statue on an annular rock face.
The site is located on a small river terrace where the Hida River meets the Hasshaku River, near the southern slope of watershed of Japan in the Northern Alps at an altitude of 680 meters. A full-scale excavation conducted from 1973 to 1979 discovered the foundations of 43 pit dwellings from the early and middle Jōmon period, arranged as an annular village surrounding a central plaza. Middens containing the remnants of nuts, such as walnuts. The pit dwellings from the latter half of the mid-Jōmon period could be divided into two types.
The Turmo was initially developed with a single-stage centrifugal compressor, annular combustion chamber and single stage turbine. Power output was from a single- stage free power turbine and was initially a very modest . During early post- war helicopter development, the use of cold and hot rotor tip-jets was widely investigated. To provide large mass-flow air for efficient operation of the tip-jets, turbomeca developed a gas turbine driven gas producer, powered by the free power-turbine of the Turmo to deliver the required gas flow.
The lengthened tail required a straight-sided bay, 30 cm (12 in) long, spliced in forward of the rear angled joint and tail assembly of the fuselage. To further aid balance, the pilot's oxygen bottles were moved aft and located in the new bay. This gave the rear fuselage a "stretched" appearance.Forsyth 1996, p. 197. Furthermore, the move to a V12 engine from a radial engine required more components to be factored into the design, most significantly the need for coolant radiators (radial engines are air-cooled). To keep the design as simple and as aerodynamic as possible, Tank used an annular radiator (the AJA 180 L) installed at the front of the engine, similar to the configuration used in the Jumo powered versions of the Junkers Ju 88. The annular radiator with its adjustable cooling gills resembled a radial engine installation, although the row of six short exhausts stacks on either side of the elongated engine cowling showed that the Jumo 213 was an inverted V12 engine.Donald 1994, p. 76. While the first few Doras were fitted with the flat-top canopy, these were later replaced with the newer rounded top "blown" canopy first used on the A-8 model.
The original French-made military ammunition tends to be scarce in the United States and is often corrosive and always Berdan-primed. The pressure is rated at around 40,000 CUP or about . The original military brass is highly prone to head separation when reloaded above 40,000 CUP. The reason is that the military Berdan-primed cartridges were made with a specially scored internal annular groove between the head and body to purposely weaken the case and prevent reloading by enemy forces, which had apparently been a problem at one time for the French when they occupied Morocco.
