Some Romanian surrealists invented a number of surrealist techniques (such as cubomania, entoptic graphomania, and the movement of liquid down a vertical surface) that purported to take automatism to an absurd point, and the name given, "surautomatism", implies that the methods "go beyond" automatism, but this position is controversial.

In addition to its obvious meaning of writing that is illegibile or for whatever other reason cannot be made out by the reader, indecipherable writing refers to a set of automatic techniques, most developed by Romanian surrealists and falling under the heading of surautomatism. Examples include entoptic graphomania, fumage and the movement of liquid down a vertical surface.

Forward movement through the water has been used as a substitute for neutral buoyancy, particularly before buoyancy compensators became available, and still is used for this purpose. The flutter kick has a tendency to kick up silt from the bottom from downwash, but is good for avoiding contact with a nearby vertical surface, as when swimming along a wall.

Western yellowjacket (V. pensylvanica) on a fennel flower (Foeniculum vulgare), near Robber's Peak, Orange, California The western yellowjacket foraging behavior is similar to other Vespula species. Yellowjackets forage for insects and dead animals for meat and plant nectar for carbohydrates. The captured prey is typically taken to a more vertical surface and malaxated by chewing off legs and wings.

Like all swifts, it is incapable of perching, and can only cling vertically to surfaces. The chimney swift feeds primarily on flying insects, but also on airborne spiders. It generally mates for life. It builds a bracket nest of twigs and saliva stuck to a vertical surface, which is almost always a human-built structure, typically a chimney.

The vertical surface was triangular overall, with a small fin but a generous and pointed balanced rudder.

This had a single landing pivot in the bow.

Xanthoparmelia mougeotii typically grows on rocks, particularly ones that are smooth, and on a vertical surface. It is often found in scree fields, rock outcrops, cliffs, on boulders, stones, pebbles or siliceous conglomerates. The lichen has a distribution in temperate locales. It is found in Europe, the United States (including Hawaii), the Dominican Republic, South America, South Africa, and Asia.

Some woodpeckers and wrynecks in the order Piciformes have zygodactyl feet, with two toes pointing forward, and two backward. These feet, though adapted for clinging to a vertical surface, can be used for grasping or perching. Several species have only three toes. The woodpecker's long tongue, in many cases as long as the woodpecker itself, can be darted forward to capture insects.

The Indian swiftlet, or Indian edible-nest swiftlet, (Aerodramus unicolor) is a small swift. It is a common resident colonial breeder in the hills of Sri Lanka and south west India. The half-cup nest is built on a vertical surface, often in a cave. The male swift uses thick saliva to construct the white, shiny nest into which two eggs are laid.

During the breeding season, each adult's salivary glands more than double in size, from in the non-breeding season to during the breeding season. Unlike some swift species, which mate in flight, chimney swifts mate while clinging to a vertical surface near their nest. They copulate daily, until the clutch is complete. The female typically lays , though clutch sizes range from .

The main product sold by PopSockets LLC is the PopSockets grip. The PopSockets grip is designed to allow easier handling of the phone. The PopSockets grip also functions as a stand, to prop a phone up while watching video. PopSockets LLC also sells the PopSockets mount, which enables one to temporarily mount one's phone on a vertical surface, such as a car dashboard or wall.

This species nests colonially in caves where it uses echolocation to navigate. The nest is a shallow cup of mossy material and saliva, usually attached to a vertical surface of a cave wall in the completely dark zone. On Guam, Neckeropsis lepiniana, is used as the nesting material and in Hawaii, a liverwort (Herberta spp.) is used. One or two white eggs form the clutch.

There, students learn the challenges of vertical-surface rescue, cliff operations, sea-cave traversing, and extreme-high-seas rescue. AHRS is considered the premier helicopter-rescue training school of its kind by most military and civilian rescue operators. Official web page, National Motor Lifeboat School, US Coast Guard official website. The Coast Guard also trains a basic form of life-saving swimmers known as Cutter Surface Swimmers.

The giant swiftlet has the largest average wingspan of all the swiftlets, at 150 millimeters. It is a fairly large swift that can grow to 16 cm in length. The female weighs 35 to 39 grams, and the male around 37 grams. Unlike other swiftlets, it builds its nest on a flat horizontal surface instead of molding it against a vertical surface with saliva.

The nest is a 5 cm wide shallow half-saucer of twigs and saliva attached to a vertical surface. This is often a man-made structure like a chimney or manhole, as with its relative, the chimney swift (C. pelagica), but natural caves and tree cavities are also used. Up to seven white eggs (average 3 or 4) are incubated by both parents for 17–18 days.

Kammback on a 1969 Fiat 850 Coupe A Kammback — also known as "Kamm tail" or "K-tail" — is an automotive styling feature. The rear of the car slopes downwards before abruptly cutting off with a vertical surface. A Kammback minimizes aerodynamic drag while maintaining a practical shape for a vehicle. The Kammback is named after German aero-dynamicist Wunibald Kamm for his work developing the design in the 1930s.

Most soap dishes are standalone accessories whose placement is at the user's discretion, though some are a built-in feature of a sink, shower, or bathtub. Standalone soap dishes may be entirely portable or may include options for semi-permanent or permanent installation on a horizontal or vertical surface. Locating a soap dish outside the perimeter of a faucet's or showerhead's stream helps the soap to avoid excess erosion.

The building has a flat composite roof with a parapet. The main entry is in the north elevation, which is the most elaborate. The entablature above the third story windows projects slightly from the vertical surface of the building, set off by a limestone stringcourse. A decorative parapet at the top of the building features a carved limestone frieze with a stylized Ionic order capital and shield design.

An elaborate entablature, including a dentil molding, cornice, medallions, and a simple frieze, encircles the building, topped by a decorative parapet that includes both a pedestal and balustrade. The main entry doors are in the west elevation, in the second and tenth bays. Stone steps provide access to the entrances, each of which is flanked by freestanding ornamental metal lampposts. Each entrance projects outward from the vertical surface of the building.

Every surface was changed from the door-cut back. The rear fenderlines dropped off from the horizontal surface to the vertical surface a couple of inches farther out than on the coupé to maintain visual proportions. The rear spoiler was also reshaped. The front and rear wheels were redesigned and a thin orange line was applied to the outer edge, a nod to the redwalls available on the 1969 Camaro.

Adult males and females emerge from the ground in the autumn. The female climbs up a tree, post or any other vertical surface and this is where mating takes place. After mating, the female attaches herself to a surface and invaginates her abdomen, creating a "marsupium" in which she lays a batch of eggs. She dies soon thereafter, her cuticle making a leathery protective casing for the eggs.

Like other dorid nudibranchs, it is a hermaphrodite. The genital opening is located on the right of the animal near the side and two individuals adopt a head to tail position for mating. Sperm is exchanged through a channel and fertilization is internal. The eggs are laid in the form of an orange-brown spiral gelatinous ribbon, deposited on a horizontal or vertical surface, which swells as it absorbs water.

Once the floor jet reaches its potential, it migrates outward until it meets a side wall or other vertical surface. Under ideal conditions, an diameter fan produces a floor jet of air approximately deep. A diameter fan produces a floor jet deep, tall enough to engulf a human standing on the floor or a cow, its initial development purpose. Commercial HVLS fans differ from residential ceiling fans with regard to diameter, rotational speed, and performance.

The rock face has been worked to a vertical surface to accept the anchor which is fastened to it, with a remnant shackle attached. The memorial includes a stone plinth bonded to the wall detailing the date and purpose of the monument. A timber safety rail fence surrounds the memorial precinct. The second item, a rock cut inscription, was inscribed on the flat (horizontal) sandstone cliff top above the actual wreck site location.

Sometimes, the wrigglers are spit onto a vertical surface rather than a pit. The young adhere to the surface because of adhesive mucus-producing glands on the top of their heads. If they fall off, they are retaken by the parents and spit back into position. This use of vertical surfaces is most commonly seen when oxygen levels are low; the parents then spit the wrigglers onto aquatic plants, near the water surface.

To operate well on vibrating surfaces, pads are usually made of soft, rubber like materials with very high friction coefficients. Designs seek to achieve certain level of adhesion (e.g. for use on vertical or very steep surfaces) without compromising easy detachment and continuous use without residual left-over. Some applications (such as sticking smartphones or tablets to vertical surface) require high degree of reliability, which is difficult to achieve without strong sticking to the surfaces.

It breeds in sheltered locations such as caves, natural rock crevices or under the roofs of houses. The nest is a half-cup of dry grass and other fine material that is gathered in flight, cemented with saliva and attached to a vertical surface. The two or three white eggs are incubated for about seventeen days to hatching. Subsequently, the chicks have a long but variable period in the nest before they are fully fledged.

The lesser swallow-tailed swift or cayenne swift (Panyptila cayennensis) is a resident breeding bird from southern Mexico and Tobago south to Ecuador, eastern Peru and Brazil. This small swift is found in range of habitats including forest clearings, more open woodland, and cultivation. The nest is tubular, wider at the top, and with the entrance at its base. It is made of plant material and attached to a branch or a vertical surface.

The protagonists of the game, Puff and Blow, each have a Methane Gas Gun which fires a cloud of immobilising gas. If this comes into contact with a bad guy, he will be absorbed into the gas and then float around the screen for a limited time. Bad guys are harmless in this state. Puff and Blow must suck the floating gas clouds into their guns and blast them out against a vertical surface.

Yaw is induced by a moveable rudder-fin. The movement of the rudder changes the size and orientation of the force the vertical surface produces. Since the force is created at a distance behind the centre of gravity, this sideways force causes a yawing moment then a yawing motion. On a large aircraft there may be several independent rudders on the single fin for both safety and to control the inter-linked yaw and roll actions.

This helped trap the shock wave under the wing between the downturned wing tips. It also added more vertical surface to the aircraft to maintain directional stability at high speeds. NAA's solution had an additional advantage, as it decreased the surface area of the rear of the wing when the panels were moved into their high-speed position. This helped offset the natural rearward shift of the center of pressure, or "average lift point", with increasing speeds.

An eyebrow piercing is a vertical surface piercing, wherein a twelve to eighteen gauge cannula needle is inserted through the bottom of the eyebrow and exits through the top of the eyebrow to permit insertion of jewellery. Those performing the piercing may use a pennington clamp to better guide the needle through the skin. A curved barbell is the most common jewellery inserted post-piercing. A piercing of underneath the eye is known as an anti- eyebrow piercing.

The tail surfaces consisted of one swept vertical surface and a pair of swept horizontal surfaces, which had zero camber. The adjustable horizontal stabilizer was attached to the sides of fuselage, at about the same height as the wing. The rudder top was made of a dielectric material, and served as a cover for the radio antenna. The airplane had a wide lower elongated fin with a rounded profile, and contained one pair of air brakes.

Pterophyllum is a small genus of freshwater fish from the family Cichlidae known to most aquarists as angelfish. All Pterophyllum species originate from the Amazon Basin, Orinoco Basin and various rivers in the Guiana Shield in tropical South America. The three species of Pterophyllum are unusually shaped for cichlids being greatly laterally compressed, with round bodies and elongated triangular dorsal and anal fins. This body shape allows them to hide among roots and plants, often on a vertical surface.

The ideal shape to minimize drag is a teardrop. However researchers including Kamm found that abruptly cutting off the tail resulted in minimal increase in drag. The reason for this is that a turbulent wake region forms behind the vertical surface at the rear of the car. This wake region mimics the effect of the tapered tail in that air in the free stream does not enter this region (avoiding boundary layer separation), therefore smooth airflow is maintained which minimises drag.

During the growing season, the sun shines on a vertical surface at an extreme angle such that much less light is available to crops than when they are planted on flat land. Therefore, supplemental light would be required. Bruce Bugbee claimed that the power demands of vertical farming would be uncompetitive with traditional farms using only natural light. Environmental writer George Monbiot calculated that the cost of providing enough supplementary light to grow the grain for a single loaf would be about $15.

A behavior called "pendeling" can then be seen at the boundaries of the territories: the two male territory owners alternate charges and retreats between them, but never go beyond the boundary, as if it were a glass wall. The males can also "parallel-run", swimming parallel to each other along the boundary. Females also engage in territorial defense, but typically less than males. The preferred egg-laying substrate is a vertical surface, ideally as part of a cave or tunnel.

Many kinds of paints and inks—e.g., plastisols used in silkscreen textile printing—exhibit thixotropic qualities. In many cases it is desirable for the fluid to flow sufficiently to form a uniform layer, then to resist further flow, thereby preventing sagging on a vertical surface. Some other inks, such as those used in CMYK-type process printing, are designed to regain viscosity even faster, once they are applied, in order to protect the structure of the dots for accurate color reproduction.

These could be operated in conjunction to act as elevators as well as assisting in the lateral control of the aircraft. A single rectangular rudder was mounted between two booms, the upper attached to the centre of the rear spar and the lower to the rear of the fuselage. A large canvas triangle was stretched between the trailing edge of the upper wing and the end of the upper tail boom. A small fixed vertical surface was also mounted above the upper wing.

He was known for doing what needed to be done and for taking an interest in "all things ingenious or intriguing." Ivan Sutherland used a light pen in his programs as did Jack Gilmore and others before him. The pens allow fine detail but drawing on a vertical surface like a CRT tires the hand quickly. There is no evidence they studied ergonomics but T-Square used an input device more like a mouse in that it rested on a horizontal surface.

Park of the Revolution is located in the southern part of the city, landscaping is decorated with high pine trees and low growing evergreen flora. The park is enriched with monuments 1961 in honor of all the fallen soldiers and participants of People's Liberation Movement. The mound makes a semicircular shape in which the inner part of the entire vertical surface paved with white marble slabs. On them are inscribed the names of 462 killed partisans from Prilep and the surrounding places.

Notable examples of dry mixture mortars which utilize methyl cellulose include tile adhesives, EIFS, insulating plasters, hand-troweled and machine-sprayed plaster, stucco, self-leveling flooring, extruded cement panels, skim coats, joint & crack fillers, and tile grouts. Typical usage is about 0.2% – 0.5% of total dry powder weight for dry mixtures. Derivatives of methyl cellulose which improve performance characteristics include hydroxypropyl methyl cellulose (HPMC) and hydroxyethyl methyl cellulose (HEMC). These derivatives typically improve the characteristics such as water retention, vertical surface slip resistance, open time, etc.

Seats for one or two passengers could be fitted in the rear with access via a triangular shaped starboard side door. The tailplane was mounted on top of the fuselage and carried horn balanced elevators. The combination of a triangular fin and straight edged rudder, which extended down to the bottom of the fuselage in a cut out between the elevators, gave the vertical surface a rather pointed look. The main undercarriage legs, with prominent shock absorbers, were mounted on the upper fuselage longerons.

Tracked Hovercraft test system, the RTV 31. The earliest examples of serious hovertrain proposals come, unsurprisingly, from Christopher Cockerell's group, organized in Hythe, Kent as Hovercraft Development Ltd. As early as 1960 their engineers were experimenting with the hovertrain concept, and by 1963 had developed a test- bed system about the size of a tractor-trailer that ran for short distances on a concrete pad with a central vertical surface that provided directional control. The prototype was pushed along its short test track by hand.

The team secured some additional funding for the construction of a scale-model system. This was built in the yard of the Hythe site, consisting of a large loop of track about three feet off the ground. By this point the basic layout had changed, with the guideway now in the form of a box girder, with the vertical pads on the sides of the guideway rather than a separate vertical surface on top of it. The vehicle itself was now flatter and wider.

The Ugly Indian conducted a comprehensive survey on their UFO Project which audited nearly 2200 pillars (metro & flyover) on 17 April 2019. The survey was conducted on this date because it was the day prior to Lok Sabha Elections (General Elections) in Bangalore; elections typically produce a slew of new posters hung on every vertical surface which would allow TUI to see if their poster deterrent designs for flyover pillars were effective.Out of the 950 flyover pillars, only 4% were found defaced or marked with posters.

Color of dorsal is dark mixed with brown and blackish hairs, and side color is pinkish cinnamon, and belly and feet have pure white color. The mouse morphological adapted to have long tail as balancing when they climb vertical surface, and large eye as activating in darkness. Adult Peromyscus attwateri's total length is usually about 182 to 220 mm with weight 25-35 grams. The tail is about 83-104mm, ear length is about 18–20 mm, and length of hind foot is about 24–27 mm.

However, the long tail was not a practical shape for a car, so automotive designers sought other solutions. In 1935, German aircraft designer Georg Hans Madelung showed alternatives to minimize drag without a long tail. In 1936, a similar theory was applied to cars after Baron Reinhard Koenig-Fachsenfeld developed a smooth roofline but with an abrupt end at a vertical surface, effective in achieving low amounts of drag similar to a streamlined body. He worked on an aerodynamic design for a bus, and Koenig-Fachsenfeld patented the idea.

A three cylinder, inverted Y configuration Anzani air-cooled engine of 26 kW (35 hp) in the nose drove a two-blade propeller. The triplane had a fixed undercarriage of wide track, with a single wheel at each end of a single axle with its extremities attached to extensions of the outer interplane struts. Its cruciform tail had horizontal surfaces mounted on the top of the fuselage; the vertical surface was trapezoidal and extended equally above and below the fuselage. A small tailskid was carried on its lower tip.

Exceptions are the black-backed woodpecker and the American and Eurasian three-toed woodpeckers, which have only three toes on each foot. The tails of all woodpeckers, except the piculets and wrynecks, are stiffened, and when the bird perches on a vertical surface, the tail and feet work together to support it. Woodpeckers have strong bills for drilling and drumming on trees, and long sticky tongues for extracting food (insects and larvae).Winkler, Hans & Christie, David A. (2002), "Family Picidae (Woodpeckers)" in del Hoyo, J.; Elliot, A. & Sargatal, J. (editors). (2002).

The game can be played on any available rectangular table on which a net may be affixed, gameplay can be altered by using different size tables which alter the available space in which to hit the ball. Alternatively a two piece table can be folded into a right angle. With the net secured to the edge of the horizontal surface and allowing a small gap between the vertical surface. The game then commences making use of the tables centre line as the deliniator for points and serves and continues using the regular table squash rules.

While most jumping spiders walk quickly, in a stop-go gait and jumping over obstacles, the movements of Phaeacius are very unusual. Phaeacius usually uses a "flattened posture" head-down on a vertical surface, with the body, legs and palps pressed against the surface, the hindmost legs upwards and the other legs downwards, and its markings and flattened body make it easily hidden against the bark of a tree trunk. Its habit of walking with its body and legs flattened against a surface helps Phaeacius to be unobtrusive.

Web of an undetermined species of Hypochilus in its 'normal' orientation Like other members of the family, Hypochilus thorelli makes a "lampshade-shaped" web. The web is usually fixed to the underside of an overhang, or sometimes on a vertical surface. The spider first makes a circular "mat" of silk and then uses this as the top of a cylindrical web that widens downwards and is open at the bottom like a lampshade. The web is held taut by threads of silk connecting it to the substrate below.

Glyph detail There is a hypothesis that provides petroglyphs of Ingá an exceptional importance from the archeoastronomical point of view. In 1976, the Spanish engineer Francisco Pavía Alemany started a mathematical study of this archaeological monument. The first results were published in 1986 by the Instituto of Arqueologia Brasileira (Pavía Alemany F. 1986). He identified in Inga a series of "bowls" and another petroglyph etched into the vertical surface of the wall of Inga that formed a "solar calendar", over which a gnomon projected the shadow of the first solar rays of every day.

The BL 9.2 also affected the development of radar. Immediately before the second world war, an army team developed a surface-scanning radar to detect enemy ships in the English Channel. By chance, in July 1939 one of these radars was being tested while the 9.2-inch battery at Brackenbury Battery outside Harwich was firing. The radar team noticed odd returns on their displays, and realised that these were due to the waterspouts caused by the shells exploding in the water creating a vertical surface off which the signals reflected.

Climbing consists of moving up or down a vertical surface using all four arms and legs to help move the body upward or downward. There are many different ways in which in animal can climb such as using alternating arms and legs, climbing sideways, fire-pole slides and head or bottom first decline. Vertical climbing is the most costly form of locomotion as the animal must defy gravity and move up the tree. This is particularly harder for animals with a larger body mass, as carrying their entire weight becomes more difficult with size.

On August 1, 1947, USS BOARFISH conducted the first under-ice transit of an ice floe in the Chukchi Sea, which was relatively unexplored at the time, while the other ships mapped its perimeter. At 2:39 PM at 72° 05' N 168° 42' W BOARFISH commenced a stationary dive and underwater transit of the ice floe. The transit took over an hour and average ice thickness was eight to ten feet thick with the deepest reading being eighteen feet thick. When she got to the other side she conducted a vertical surface.

In 1939, Edmund T. "Eddie" Allen hired Schairer to be chief of the aerodynamics unit at Boeing, replacing Ralph Cram, who had been killed in the crash of the Boeing 307 prototype.The Boeing 367-80; Jet Transport Prototype Mechanical Systems Retrieved 3 August 2011. In this position, he helped develop and test the Boeing 307 Stratoliner, the first pressurized airliner, including the redesign of the vertical tail in response to the March 18, 1939 crash of the prototype.Schairer, George S. "Directional Stability and Vertical Surface Stalling", Journal of the Aeronautical Sciences, Vol.

Nesting mossy-nest swiftlets The nest of many species is glued to a vertical surface with saliva, and the genus Aerodramus use only that substance, which is the basis for bird's nest soup. The eggs hatch after 19 to 23 days, and the young leave the nest after a further six to eight weeks. Both parents assist in raising the young. Swifts as a family have smaller egg clutches and much longer and more variable incubation and fledging times than passerines with similarly sized eggs, resembling tubenoses in these developmental factors.

The flag of Maastricht (Dutch: Vlag van Maastricht, Limburgish (Maastrichtian variant): Veendel vaan Mestreech or Drappo vaan Mestreech) is the official flag of Maastricht, the capital city of the province of Limburg, Netherlands. It constitutes a red vertical surface with a five-pointed star on its left side (a star that is common among many flags e.g., the flag of Chile). It had been a historical flag, with its first image of appearance dating from 1549, of the municipality but was replaced in 1938 with a flag similar in design to the Polish flag.

The Organ pipe mud dauber ranges from Southeastern Canada to Eastern United States Mud daubers use tree holes or the underside of bridges to construct their nests out of mud. Nest site choice usually depends on 3 specifications: a smooth vertical surface with ample shade and rainfall protection, a source of mud nearby, as well as an adjacent forest. The females form long mud tubes consisting of multiple cells, which they will fortify with paralyzed spiders. The female then lays an egg in each cell, leaves the nest and, once hatched, the larvae feed on the spiders.

The Cloud Dancer II features a single four-bladed main rotor, a two-seats in side-by-side configuration enclosed cockpit, tricycle landing gear with wheel pants and a twin cylinder, air- cooled, four-stroke, turbocharged Rotortec MPE engine that was developed in- house and is mounted in pusher configuration. It drives a three-bladed composite propeller though a planetary reduction drive. The aircraft fuselage and the three vertical surface tail are made from aluminum and Kevlar composites. Its diameter rotor has a chord of and is equipped with a micro- processor controlled hydraulic pre-rotator.

A window tomb in the Salina Catacombs The site comprises five hypogea cut into the vertical surface of a small quarry. A number of other openings can be seen in rocky outcrops around the site and at least one hypogeum has been damaged by further quarrying, resulting in the destruction of a number of burials. The most impressive hypogeum is adorned with two decorated pillars, an agape table and two baldacchino tombs, rarely found outside the catacombs of Rabat. The window tombs that surround the agape table suggest that it was an important feature of the catacomb.

Muhammad Ali's star was granted after the committee decided that boxing could be considered a form of "live performance". Its placement, on a wall of the Dolby Theatre, makes it the only star mounted on a vertical surface, acceding to Ali's request that his name not be walked upon, because he shared his name with the Prophet Muhammad. All living honorees have been required since 1968 to personally attend their star's unveiling, and approximately 40 have declined the honor due to this condition. The only recipient to date who failed to appear after agreeing to do so was Barbra Streisand, in 1976.

The Indian spotted creeper has grey and white spotted and barred plumage, clearly different from the treecreepers of the subfamily Certhiinae. It weighs up to 16 grams, twice as much as treecreepers of similar length (up to 15 cm). The Indian spotted creeper has a thin pointed down-curved bill, a bit longer than the head, that it uses to extricate insects from bark, but it lacks the stiff tail feathers which treecreepers use to prop themselves on the vertical surface of tree trunks. They have a whitish supercilium contrasting with a dark eye stripe and white on the throat.

Before the arrival of European colonists into North America, the chimney swift nested in hollow trees; now, it uses human-built structures almost exclusively. While the occasional nest is still built in a hollow tree (or, exceptionally, in an abandoned woodpecker nest), most are now found in chimneys, with smaller numbers in airshafts, the dark corners of lightly used buildings, cisterns, or wells. The nest is a shallow bracket made of sticks, which the birds gather in flight, breaking them off trees. The sticks are glued together (and the nest to a vertical surface) with copious amounts of the bird's saliva.

The 2001 biopic Ali garnered a Best Actor Oscar nomination for Will Smith for his portrayal of Ali.. Prior to making the film, Smith rejected the role until Ali requested that he accept it. Smith said the first thing Ali told him was: "Man, you're almost pretty enough to play me." In 2002, Ali was honored with a star on the Hollywood Walk of Fame for his contributions to the entertainment industry. His star is the only one to be mounted on a vertical surface, out of deference to his request that the name Muhammad—a name he shares with the Islamic prophet—not be walked upon.

The gas will initially be distributed throughout the magma as small bubbles, that cannot rise quickly through the magma. As the magma ascends the bubbles grow through a combination of expansion through decompression and growth as the solubility of volatiles in the magma decreases further causing more gas to exsolve. Depending on the viscosity of the magma, the bubbles may start to rise through the magma and coalesce, or they remain relatively fixed in place until they begin to connect and form a continuously connected network. In the former case, the bubbles may rise through the magma and accumulate at a vertical surface, e.g.

A shelf is also known as a counter, ledge, mantel, or rack. Tables designed to be placed against a wall, possibly mounted, are known as console tables, and are similar to individual shelves. A shelf can be attached to a wall or other vertical surface, be suspended from a ceiling, be a part of a free-standing frame unit, or it can be part of a piece of furniture such as a cabinet, bookcase, entertainment center, some headboards, and so on. Usually two to six shelves make up a unit, each shelf being attached perpendicularly to the vertical or diagonal supports and positioned parallel one above the other.

Flying with nesting material near coastal cliffs in Japan Most Apus swift species nest in rocky areas, and the majority will accept human habitations as a substitute for natural sites. The Pacific swift is a colonial species which nests in sheltered locations such as caves, crevices in vertical rock faces (including sea-cliffs), or under the eaves of houses. The nest is a half-cup of feathers, dry grass and other light vegetation collected in flight, cemented with saliva and attached to a ledge or vertical surface with the same substance. Two or three eggs is the normal clutch, the number varying with geographical location.

Twin tail of Avro Lancaster The twin tail of a Chrislea Super Ace, built in 1948 High-mounted twin tail of Blackburn Beverley transport Separating the control surfaces allows for additional rudder area or vertical surface without requiring a massive single tail. On multi-engine propeller designs twin fin and rudders operating in the propeller slipstream give greater rudder authority and improved control at low airspeeds, and when taxiing. A twin tail can also simplify hangar requirements, give dorsal gunners enhanced firing area, and in some cases reduce the aircraft's weight. It also affords a degree of redundancy—if one tail is damaged, the other may remain functional.

Andrena agilissima is a southern and central European species of mining bee, recognizable by its bluish color, which is found from the Netherlands and Poland in the north south through the islands of the Mediterranean to North Africa, where it is widespread, and as far east as the former Czechoslovakia, it is absent from Great Britain but does occur on the Channel Islands. It is a typical hollow way bee. A. agilissima needs a vertical surface to nest on and it typically feeds on flowers of plants in the mustard family for food. In Southern Germany, it collects its pollen from the wild mustard plant (Sinapsis arvensis).

The Circuit of Britain biplane was a four-bay tractor biplane with a square- section fuselage with the forward part covered with aluminium back to the aft cockpit and the remainder covered with fabric. The forward sections of the longerons were made of ash and the rear sections of spruce. Lateral control was effected by ailerons on both the upper and lower wings, which were staggered and had spruce spars spindled to an I section and hollow interplane struts."The Sopwith Tractor Water-Plane" Flight 16 August 1913 The tail surfaces consisted of unbalanced elevators mounted on the large semi-circular tailplane and an aerodynamically balanced rudder, with no fixed vertical surface.

The Excalibur was designed as "clone" of the Quad City Challenger II aircraft. The company took the basic Challenger design and incorporated many changes, including mounting the engine upright allowing larger propellers and the Rotax gearbox to be mounted, lengthening the tailboom and enlarging the tail vertical surface to increase stability, shortening the ailerons and replacing control cables with torque tubes. The optional Dacron covering on the Challenger was replaced with Superflite standard aircraft fabric, the fuselage was lengthened to give more backseat room and the nosecone was reduced in size to provide better over-the-nose visibility. The design was also streamlined to reduce drag and round cross- section wing struts were replaced with aerodynamic extrusions.

Westland SA-341D Gazelle, 1975 Originally developed as a replacement to Aérospatiale's Alouette helicopter, some aspects of the Gazelle such as its purpose and layout were based on the previous model. The Gazelle featured several important innovations. It was the first helicopter to carry a fenestron or fantail; this is a shrouded multi- blade anti-torque device housed internally upon the vertical surface of the Gazelle's tail, which replaces a conventional tail rotor entirely. The fenestron, while requiring a small increase in power at slow speeds, has advantages such as being considerably less vulnerable and with low power requirements during cruise speeds, and has been described as "far more suitable for high-speed flight".

The autogyro's two-blade rotor is mounted on a mast largely within a wide chord fairing, though with a significant part exposed below the rotor head. The other differences are in the empennage; the MAI-208 has a straight edged, slightly tapered tailplane and elevators with a cutout for rudder movement but the swept vertical surface of the MAI-223 was replaced by a small triangular fin carrying an almost semicircular rudder. By HeliRussia 2010 this had been reworked, with a wider chord, round topped rudder and a long fin/fillet with an almost horizontal upper edge. The first flight was originally scheduled for 2009, then revised to 2010, though it remained unannounced at HeliRussia 2010.

Gathering mud Verkhniye Mandrogi, Russia A mother flying back to a full nest in the eaves of a house in Kent, England Collecting mud Collecting mud for nests in Denmark Delichon urbicum – MHNT The common house martin was originally a cliff and cave nester, and some cliff-nesting colonies still exist, with the nests built below an overhanging rock. It now largely uses human structures such as bridges and houses. Unlike the barn swallow, it uses the outside of inhabited buildings, rather than the inside of barns or stables. The nests are built at the junction of a vertical surface and an overhang, such as on house eaves, so that they may be strengthened by attachment to both planes.

The Ghost Rider is a human who can transform into a skeletal superhuman wreathed in ethereal flame and given supernatural powers. The motorcycle he rides can travel faster than any conventional vehicle and can perform seemingly impossible feats such as riding up a vertical surface, across water, and leaping across great distances that normal motorcycles cannot. The Ghost Riders are virtually indestructible and notoriously hard to injure by any conventional means, as bullets and knives usually pass through them without causing pain (knives are shown to melt while in their body).Ghost Rider (2007 film) It is possible that they are genuinely immortal, as it is said that God created them and only God can destroy them.

The turbosail' or French ' is a marine propulsion system using a sail-like vertical surface and a powered boundary layer control system to improve lift across a wide angle of attack. This allows the sail to power the boat in any direction simply by moving a single flap at the back of the sail, unlike conventional sails which have to be continually adjusted to react to changes in the relative wind. The turbosail was first developed in a large scale application by Jacques-Yves Cousteau who commissioned the Alcyone to test the concept in production. The larger Calypso II was also designed to use a turbosail, but that design was not built.

This could be opened up into a sloping vertical surface in front of the driver providing a bow of a boat hull, about level with the top of the turret. Fabric formed the rest of the water barrier, folding up from compartments lining the upper corner where the side met the top of the hull, and held up at the back with poles. The front of the "hull" was provided with a plastic window, but in practice it was found that water splashing onto it made it almost useless, and the driver instead usually had to take steering directions from the vehicle commander. The M2 Bradley adopted a similar solution, but dropped it with upgraded armor.

Antrodia serialis is similar in appearance The perennial fruit bodies of A. serialiformis are effused-reflexed (that is, on a vertical surface that is partially lying flat on the substrate with the hymenium covering the upper surface, and partially pileate). In its upper part it has small caps that are often elongated along the growing surface, up to or more in length, with a tough texture. The individual caps, which reach dimensions of up to by , have roughly horizontal upper surfaces that are velvety, and brownish with a narrow white margin. On the underside of the cap, the pore surface is initially white, but turns dirty brown as it matures. The individual pores are round and small, numbering from 3 to 4 per millimeter.

The Monoplane was a mid-wing tractor configuration monoplane powered by a 50 hp Gnome Omega seven-cylinder rotary engine driving a two-bladed Chauvière Intégrale propeller. The fuselage was a rectangular-section wire-braced box girder, with the forward part covered in plywood and the rear part fabric covered: the rear section was left uncovered in some examples. The two-spar wings had elliptical ends and were braced by a pyramidal cabane in front of the pilot and an inverted V-strut underneath the fuselage, behind the undercarriage. Lateral control was effected by wing warping and the empennage consisted of a fixed horizontal stabiliser with tip- mounted full-chord elevators at either end and an aerodynamically balanced rudder, with no fixed vertical surface.

The vessel had a steel hull, and a single 636 Nhp (3,200 ihp) vertical surface- condensing direct-acting reciprocating quadruple expansion steam engine, with cylinders of , , and diameter with a stroke, that drove a single screw propeller and moved the ship at up to . The steam for the engine was supplied by three single-ended Scotch boilers fitted for oil fuel. The sea trials were held on October 1, 1920 in the Massachusetts Bay during which the vessel managed to reach maximum speed of and a mean speed of exceeding contract requirements. Following successful completion of full load run, the ship was transferred to her owners and sailed for Philadelphia and from there proceeded on her shakedown trip down to Gulf ports of Texas to load her first cargo for the Orient.

The net cost of transport (NCT), which indicates the amount of energy required to move a unit of mass a given distance, for a snake moving with a lateral undulatory gait is identical to that of a limbed lizard with the same mass. However, a snake utilizing concertina locomotion produces a much higher net cost of transport, while sidewinding actually produces a lower net cost of transport. Therefore, the different modes of locomotion are of primary importance when determining energetic cost. The reason that lateral undulation has the same energetic efficiency as limbed animals and not less, as hypothesized earlier, might be due to the additional biomechanical cost associated with this type of movement due to the force needed to bend the body laterally, push its sides against a vertical surface, and overcome sliding friction.

The round dance uses the position of the sun to indicate the direction from the hive to the food source in the same way that the waggle dance does The round dance uses the position of the sun in order to indicate the direction of the food source in the same way that the waggle dance does. On the vertical surface of the comb, the forager expresses the angle between the position of the sun and the path to the food source through an angular deflection from perfect vertical. Honey bees use both the position of the sun and the polarization patterns of a blue sky to communicate the direction to the food source. Support for this theory rests in the observation that honey bees can still recognize the sun's position when it is obscured by a cloud or a mountain, for example.

The submachine gun consists of the following main components: the barrel, frame (containing the shoulder stock, pistol grip and forward grip), slide, return spring and spring guide rod and the magazine. The slide houses an inertia buffer and spring retarder mechanism, designed to reduce the weapon's rate of fire down to 650 rounds/min from a natural frequency of about 840 rounds/min. The slide telescopes around the barrel up to the muzzle and has an extension that serves as a recoil compensator which deflects muzzle gases upward to counteract the natural rise of the weapon when firing in automatic mode. The compensator is shaped like a long spoon and can be used to cock the weapon with just one hand, accomplished by pressing the compensator up against a rigid vertical surface until the slide locks back.

Plaque in tribute to Claude Bernard, at Collège de France in Paris, France. An example of a lightbox used as a commemorative plaque This sign in Dickson, Australian Capital Territory commemorates the establishment of Canberra's first aerodrome and its first fatality in the 1920s. A commemorative plaque, or simply plaque, or in other places referred to as a historical marker or historic plaque, is a plate of metal, ceramic, stone, wood, or other material, typically attached to a wall, stone, or other vertical surface, and bearing text or an image in relief, or both, to commemorate one or more persons, an event, a former use of the place, or some other thing. Many modern plaques and markers are used to associate the location where the plaque or marker is installed with the person, event, or item commemorated as a place worthy of visit.

Instrument panel of the V-Twin The Velocity V-Twin is a four-seat (with a five-seat option), retractable tricycle landing gear, composite construction aircraft with a twin engined pusher configuration and the canard layout of the Velocity XL single engine aircraft. Its fuselage is that of the XL-RG, with the addition of the single, vertical surface which replaces the twin end plate fins of the smaller XL. The aircraft features "gull wing" car-like doors and dual sidestick controllers. The flight control surfaces are the same as those of the XL. The aircraft's design goal was to offer the safety of twin engines without the stall and spin risks of a conventional twin during single-engine operations. The rear-facing pusher propellers are mounted close together where the fuselage cross-section tapers, reducing asymmetrical single-engine thrust yawing compared to conventional twin-engine aircraft.

The "D-500 with Ram Induction" with dual four-barrel carburetors was optional, along with a three-speed TorqueFlite automatic transmission. LIke all contemporary Chrysler automobiles, the automatic transmission was controlled by mechanical pushbuttons on the left side of the instrument panel. The Matador (and the similar, better-trimmed Polara) featured styling cues that were carried over from 1959 models, themselves an evolution of Virgil Exner's "Forward Look" cars introduced in 1957. Now built on a new unibody chassis, the 1960 Matador continued the Dodge styling hallmarks of stacked "jet pod" taillights, however, the size of the lights was greatly exaggerated, with the lower light set into the rear bumper. The design also incorporated Dodge’s trademark (shortened) tailfins, which included small vertical taillight lenses placed on the vertical surface at the back of the fin; again. The purpose of the shortened fin was meant to exaggerate the length of the “jet pods” holding the taillights.

The design also incorporated Dodge's trademark shortened tail fins, which, on the Polara, included small vertical tail light lenses placed on the vertical surface at the back of the fin; again, the purpose of the shortened fin was meant to exaggerate the length of the "jet pods" holding the tail lights. The fins on Darts were shorter both in length and height because unlike the full sized Dodge's, the Polara and Matador, the Darts were based on the Plymouth and used much Plymouth sheet metal forms and the Plymouth rear door. The Plymouth rear door did not have any part of the fin whereas on the full sized Dodges the fin actually started on the rear door (on the 4-doors) and continued back from there. This allowed the fin to start sooner, on the door, and end sooner, relative to the tip of the round tail light and still appear as long or longer than on the Dart.

Avro Vulcan XM607 XV656, a Royal Navy Westland Sea King The registration numbers are normally carried in up to four places on each aircraft; on either side of the aircraft on a vertical surface, and on the underside of each wing. The under-wing registration numbers, originally specified so that in case of unauthorised low flying civilian personnel could report the offending aircraft to the local police, have not been displayed since the 1960s, as by then jet aircraft speeds at low level had made the likelihood of a person on the ground being able to read, and thus report them, increasingly remote. The registration number on each side is usually on the rear fuselage, but this can vary depending on the aircraft type, for instance the delta winged Gloster Javelin had the registration number on the forward engine nacelle, and the Avro Vulcan had the registration number on its tail fin. Helicopters have only carried registration numbers on each side, either on the tail-boom or rear fuselage.
