The initial singles, "Ch-Ching" and "Romeo," have lush synth orchestration and hum-along hooks; the greatest appeal rests in the singer Caroline Polachek's jazz-inflected vocals, which fascinate in their agile leaps and slightly mechanical serration.

The story of generations of people who felt the lash of bondage, the shame of servitude, the sting of serration, but who kept on striving and hoping and doing what needed to be done so that today, I wake up every morning in a house that was built by slaves.

A 7.7 millimeter precanine diastema is located behind the upper incisor on that same right side. This seems large, but when compared to incisors of dinocephalians and anomodonts, they are relatively small. Serration is present in NMQR 1702 but it is faint compared to the intense serration of BP/1/816. It is speculated that these differences in serration between NMQR 1702 and BP/1/816 might be ontogenetic, for it is common for juvenile therapsids to lose serration as they get older.

Its supraacicular simple chaetae shows distal serration, while subacicular chaetae are compound, its blades showing serration. Its pygidium has a terminal anus, with two pygidial cirri being laterally inserted, as well as an unpaired appendage that is placed ventrally.

At least five classes can be identified according to the stress-strain relation appearance of Serration.

Serration is present on the last ray of the dorsal and anal fins, and the caudal fin is forked.

As is common in serrated leaves, each serration has a central vein extending to its tip. However, the serration vein originates from lower down the central vein of the leaflet, typically opposite to the position of, not the first notch down, but the next notch. This means that on its way from the midrib of the leaflet to the point of the serration, the vein serving the tip of the serration passes close by the intervening notch. Sometimes the vein will actually pass tangent to the notch, but often it will pass by at a small distance, and when that happens a spur vein (occasionally a pair of such spur veins) branches off and joins the leaf margin at the deepest point of the notch.

The incisors have an oval cross-section and longitudinal striations. Their upper canine’s edges are preserved well enough to conclude they lack serration, but the lower canines are not still sharp enough to make any conclusions about their serration. The lower canines are slightly longer than the upper canines. The post-canine teeth are, as of now, the most distinct feature of Progalesaurus.

Full rubber serration tests were performed on various tracks such as Fiorano, Imola, Jerez and Mugello resulting in an optimal compromise between grip, endurance and wear.

The largest known tooth is 5.8 cm in height. Like that of later sauropods, the teeth are spoon shaped and show wrinkled enamel. A basal trait is the coarse serration.

The mine consists of a rather broad corridor that often follows the serration of the leaf margin. The frass line is quite broad, especially in the first part of the mine.

Individual sheets can be separated at the perforation (leaving a slight serration), and sheets also have edges with punched holes, which also can be removed at the perforation (one typical format).

Albertosaurus had similarly crack-like serrations, but, at the base of each serration Abler discovered a round void, which would have functioned to distribute force over a larger surface area. This void, termed an ampulla, would hinder the ability of the "crack" formed by the serration to propagate through the tooth. The phytosaur was found to lack adaptations for preventing its dental "cracks" from propagating. Abler examined another sort of prehistoric predator, Dimetrodon, and found that it also lacked adaptations for guarding against crack propagation.

Several more recent studies have raised the possibility that the dinosaur was omnivorous and used its tusks for prey killing during an occasional hunt. In 2000, Paul Barrett suggested that the shape of the premaxillary teeth and the fine serration of the tusks are reminiscent of carnivorous animals, hinting at facultative carnivory. In contrast, the muntjac lacks serration on its tusks. In 2008, Butler and colleagues argued that the enlarged tusks formed early in the development of the individual, and therefore could not constitute sexual dimorphism.

Elongated, fat crypts and little to no serration. Therefore, they may not be obvious without comparing to adjacent normal intestinal wall. They are filled with goblet cells, extending to surface, which commonly has a tufted appearance.

Fixed fanlike reflecting structures in the inlet tunnel divert radar energy away from the rotating fan blades.Donald 2004, pp. 50–51, 56. The Super Hornet also makes considerable use of panel joint serration and edge alignment.

The jawss are large, but imperfectly cornified. The jaws are angular and minutely, irregularly serrate. They are composed of numerous minute prismatic rods. On the margin many of these rods are transverse and project slightly, forming a minute serration.

It possesses no eyes, its mandibles being L-shaped, counting with anterior serration. Its maxillae exhibits 7 free denticles. It also counts with two peristomial segments without setae. Its parapodia has dorsal ventral cirri, with simple supraacicular chaetae and compound subacicular chaetae with serrated blades.

The leaves are palmately lobed and roughly shaped like a hand. They grow up to 30 cm wide and the margins are entire (no serration). The fertile fronds are a set of small tapering sporophores that bear the spores. There are several to many at the base of each leaf blade.

Its leaves are dark and lustrous on the upper surface. It produces umbels of white flowers in April through June. It is similar to Angelica keiskei, but differs in several key features. Angelica japonica can be distinguished its red-striped stem, and leaves that are thicker with less coarse serration.

Its body shape is elongated, with a uniform width for the majority of its length. It is transparent in colour, white eggs being visible in females. It lacks eyes; it possesses long, cirriform paired antennae, with palps being inserted lateroventrally on the prostomium. Its mandibles are rod-like, and lack serration.

It is often grown as an ornamental tree, and used in bonsai. There are two varieties, Zelkova serrata var. serrata in Japan and mainland eastern Asia, and Zelkova serrata var. tarokoensis (Hayata) Li on Taiwan which differs from the type in its smaller leaves with less deeply cut serration on the margins.

Micrograph of a sessile serrated adenoma. H&E; stain Sessile serrated adenomas are characterized by (1) basal dilation of the crypts, (2) basal crypt serration, (3) crypts that run horizontal to the basement membrane (horizontal crypts), and (4) crypt branching. The most common of these features is basal dilation of the crypts.

Leaves alternate, firm, heavy and toothed, but not toothed at the base. The leaf serration is more evident and more widely spaced than in the white hazelwood. The leathery leaves "rattle" together when a branch is shaken. The leaf shape is elliptic or wide lanceolate 12 to 18 cm long to a short leaf tip.

Long lanceolate leaves 6-12 inches (15–30 cm) long with an attractive bluish-green upper surface, a light green midrib and side nerves. The underside of the leaves is a deep reddish purple. The leaf stems are short in proportion to the leaf blade. Several forms are sold in the aquarium trade differing in colour and serration of the leaf edge.

There are two periods of occupation-an early period when Moche ceramics were in use, and a later period characterized by the use of Chimu ceramics. Brick serration used in construction allows us to see a chronology of occupation within each of those times of occupation. Pacatnamu was unoccupied before the end of Moche IV or the beginning of the Moche V (ca. A.D. 600).

Vegetative phase change is the juvenile-to-adult transition in plants. This transition is distinct from the reproductive transition and is most prolonged and pronounced in woody species. Manipulating phase change may be an important avenue for plant improvement. In the model plant Arabidopsis thaliana, vegetative phase change is relatively subtle: leaves become more curled, with an increased number of abaxial trichomes, and increased serration.

Basal leaves are oblanceolate in shape and have petioles. Cauline leaves, those growing along the stem, are ovate to ovate-lanceolate in shape, with alternate attachment to stem, sessile, acuminate at the base, acute at the tip. Leaf margins are entire, or smooth and lacking teeth or serration. Leaf texture is sericeous adaxially (above) and abaxially (below), giving the leaves a silvery-grey appearance.

Leaves ovate or elliptic in shape, 6 to 12 cm long, 1.5 cm to 6 cm wide with a sharply angled tip. Leaves are opposite on the stem, prominently toothed, 7 to 9 teeth on each side of the leaf. The bottom third of the leaf is without leaf serrations. The point of the leaf base to the first serration is almost a straight line.

Diet is largely deduced by the tooth morphology, tooth marks on bones of the prey, and gut contents. Some theropods, such as Baryonyx, Lourinhanosaurus, ornithomimosaurs, and birds, are known to use gastroliths, or gizzard-stones. The majority of theropod teeth are blade-like, with serration on the edges, called ziphodont. Others are pachydont or phyllodont depending on the shape of the tooth or denticles.

Leaf margins are serrated with blunt tips and a black gland at the apex of each serration. Leaf shape ranges from lanceolate elliptical to oblanceolate with an acute apex and leaf base which narrows into a short petiole. Flowering occurs in late spring and often again in autumn. The flower heads, known as inflorescences, are borne in terminal racemes which are about the same length as the leaves.

The lateral line has an irregular zigzag pattern. The head is flattened anteriorly with a terminal mouth. There are three pairs of thread- like barbels, one pair maxillary and two pairs mandibular. The dorsal fin and pectoral fins have large spines; the dorsal fin spine has a lower degree of serration than the pectoral fin spines, which is always serrated strongly on the entire length of both margins.

The maxilla contains specimens largest teeth and is extended posterior to the center of the triangular lateral temporal fenestra. The maxilla, which is longer compared to other 'pelycosaurs' contacts the quadratojugal in this specimen. The lacrimal is a sheet of bone that covers most of the anterior orbital margin and constricts the front of the orbit. The jugal has a unique lateral serration and narrow postorbital ramus similar to Varanops.

Currie, P.J., Rigby, Jr., J.K., and Sloan, R.E., 1990, "Theropod teeth from the Judith River Formation of southern Alberta, Canada", pp. 107–125 in: K. Carpenter and P. J. Currie (eds.), Dinosaur Systematics: Perspectives and Approaches. Cambridge University Press, New York One study, by Sunny Hwang, showed that the tooth enamel is identical to that found in Byronosaurus, a troodontid known from juveniles with serration-less teeth.Hwang, S.H. 2005.

Tooth from Megalosaurus Dental findings are frequently used to differentiate between various theropods and to further inform cladistic phylogeny. Tooth morphology and dental evolutionary markers are prone to homoplasy and disappear or reappear throughout history. However, megalosaurids have several specific denture conditions that differentiate them from other basal theropods. One dental condition present in Megalosauridae is multiple enamel wrinkles near the carinae, the sharp edge or serration row of the tooth.

In some species, the basal leaves are shed before flowering. The leaf margins are most commonly entire, but often display heavier serration. Some leaves may display trinerved venation rather than the pinnate venation usual across Asteraceae. The flower heads are usually of the radiate type (typical daisy flower heads with distinct ray and disc florets) but sometimes discoid (with only disc florets of mixed, sterile, male and bisexual types).

Llanocetus had several ancient characteristics reminiscent of archaeocetes. The dental formula, , indicating number of, in order, incisors, canines, premolars, and molars in one half of a jaw, is similar to basilosaurid archaeocetes. However, the broad snout is unlike archaeocetes. Wearing patterns on the cheek teeth, the molars and premolars, indicate they sheared passed each other while biting, which would have given Llanocetus the ability to slice through flesh, and serration wearing indicates a gripping function.

They have 10 dorsal spines, 9 dorsal soft rays, 2 anal spines, 7 anal soft rays, and 25 vertebrae. The body is elongated an compressed with large cycloid scales. Body uniformly blackish- brown in young, black dorsally, paler ventrally in adults. It is distinguished by its anal fin element counts, lack of fin spine with serration on the anterior edge, and 3 to 6 large canine-like teeth on lateral side of the lower jaw.

The oval grouper has a compressed, oval-shaped body and its depth is 2.0 to 2.8 times its standard length. It has an oblique mouth and the lower jaw projects beyond the upper jaw. The dorsal profile of the head is convex while the intraorbital area is rather wide and convex. The preopercle is not smoothly rounded, but is not sharply angled, and has fine serration on its margin which are enlarged at its angle.

Caucasian spinach has green, heart-shaped (cordate) leaves, often slightly crimped, but without serration or lobing, which taper to a narrow point (acumiate), and sometimes have very soft, almost silky hairs on them. Hablitzia's leaf-surface is more or less matt, and the veins are arranged around a single, central axis. The stems are generally green, with noticeable ridges running their length and can be flushed red. The leaves are edible, similar to those of the related spinach.

Tooth of cf. R. isosceles with close up of denticles The holotype specimen of Richardoestesia gilmorei (NMC 343) consists of the pair of lower jaws found in the upper Judith River Group, dating from the Campanian age, about 75 million years ago. The jaws are slender and rather long, 193 millimeter, but the teeth are small and very finely serrated with five to six denticles per millimeter. The serration density is a distinctive trait of the species.

These include the work material properties, the grit and abrasive type of the grinding belt, belt speed, belt sequences, contact wheel hardness and diameter, serration, type of lubricant (or dry) and grinding pressure. Changing these variables will affect the performances of the belt grinding process. In the wide belt method, a contact wheel supports the abrasive belt. The selection of the contact wheel and abrasive to match the grinding parameters required for a specific operation is very critical.

Skull of Aerosaurus The skull is 1/4 of the precaudal length of the skeleton with a jaw articulation far back seen in Varanops. The snout is long and low with an lessen inclined occiput. The dermal bones are shallow, irregular with pits and grooves and below the orbit we find a saw- like serration that hasn't been seen in other 'pelycosaurs'. The skull roof has large round orbits and an undetermined laterally expanded prefrontal process.

There is strong serration along the margins of the leaf tip, although a hand lens is usually required to see this. The leaves are also strongly plicate (folded along an axis) on either side of a central nerve (midrib) running length-wise through the leaf. The deepness of this pleating helps differentiate D. dicarpum from other Dicranoloma species. Another distinguishing feature is aggregated sporophytes, with 1-10 capsules produced from a single perichaetium (see Figure 2).

Plants in the genus Diocirea are small, multi-stemmed shrubs, rarely growing to a height of with a spread of . Their branches and leaves have many, sometimes raised glands, producing a resin which often gives the foliage a bluish-green tinge. Their leaves range in length from to , lack serration on their margins and are usually glabrous. The flowers appear singly in the axils of the leaves, lack a stalk and have 5 green, egg-shaped, sepals and 5 petals.

The dinosaur Albertosaurus had similarly crack-like serrations, but, at the base of each serration was a round void, which would have functioned to distribute force over a larger surface area and prevent the stresses of feeding from causing the crack to spread through the tooth. Unlike Albertosaurus, Dimetrodon teeth lacked adaptations that would stop cracks from forming at their serrations. The teeth of D. teutonis lack serrations, but still have sharp edges. A 2014 study shows that Dimetrodon was in an arms race against its prey.

After flowering fruits called achenes are formed in a small cluster, each achene is 3.5–5 mm long, lacks wings and has a straight or partly curved beak that is 1–1.5 mm long. Both the Latin and common names reference the leaf shape, which is thinner and with distinctive serration when compared to A. quinquefolia. It is native to the eastern United States in North Carolina, South Carolina, Virginia, and West Virginia. Anemone lancifolia is normally found growing in rich damp soils in woods.

Toe cap detail of a man's semi-brogue (or half brogue) dress shoe Semi-brogues (also known as half brogues) are characterised by a toe cap with decorative perforations and serration along the cap's edge and includes additional decorative perforations in the center of the toe cap. The half brogue was first designed and produced by John Lobb Ltd. as an Oxford in 1937 in an effort to offer his customers a shoe more stylish than a plain oxford, yet not as bold as a full brogue.

The increase in suture complexity over the 108 m.y. duration resulted from the iterative of addition of umbilical lobes, serration of lobes, and the subdivision of lateral and ventral lobes. As many as 12–15 replicate, U-shaped umbilical lobes, originating at the umbilicus and migrating across the flanks were added to the sutures during both ontogeny and phylogeny. Not only did the Prolecanitida evolve their sutures differently than in the Goniatitda, by increasing the number of umbilical lobes rather than by subdivision of the lateral saddle, their body chambers were short by comparison.

Ed.s Tanke, D. H., Carpenter, K., Skrepnick, M. W. Indiana University Press. Tyrannosaurid teeth were used as holdfasts for pulling meat off a body, so when a tyrannosaur would have pulled back on a piece of meat, the tension could cause a purely crack-like serration to spread through the tooth. However, the presence of the ampulla would have distributed these forces over a larger surface area, and lessened the risk of damage to the tooth under strain. The presence of incisions ending in voids has parallels in human engineering.

The Simpson and Suwannee points, found in Florida and the Southeastern United States, are similar to the Golondrina in shape and age. The Dalton point, found in the central United States, shares a similar outline and basal corner auriculation with Golondrina, which may imply that they are part of a series. Identification is made by examination of the blade edges—Golondrina exhibits much less serration. The Meserve type has also been known to cause confusion, as it is considered a resharpened variant of the Plainview and Golondrina types.

While Faulwetter et al. researched the soft bottom benthos of Haifa Bay, several individuals of the Sphaerosyllis exhibited features which did not correspond to any known Sphaerosyllis species. These characteristics were: falcigers with prominent serration and with a subdistal spine present in all chaetigers; a subdistal spine on the blades of some of its falcigers (also found in S. hystrix and S. boeroi). The authors then re-examined material of Sphaerosyllis hystrix from previous finds, which revealed some individuals possessed a subdistal spine on the blades of anterior falcigers and also in posterior chaetigers.

Cephalopholis sonnerati has a body which is 2.3 to 2.8 times as long as it is deep using standard length. The dorsal profile of the head in adults is straight to concave, although the nape is markedly convex. The preopercle is rounded and has fine serrations along its margins, with a shallow incision immediately above its angle, the lower edge has irregular serration and some of these are enlarged into small, exposed spines. The dorsal fin contains 9 spines and 14-16 soft rays while the anal fin has 3 spines and 9 soft rays.

Another species noted for its divergent teeth is P. lutugini, where knowledge of the teeth mainly comes from isolated specimens. Known teeth are strongly bicarinate with a weak serration on both carinae. The carinae then divide the teeth into lingual and labial surfaces, with the lingual surface being more convex and large in comparison with the labial. The teeth have a slight posterior and medial recurvature and are noted for having smooth surfaces (which is different from other species of Prognathodon) except for minor wrinkles at the tips of the tooth crowns.

Such ornamentation could potentially strengthen the teeth. The blunt tip and roughened surface suggest a tooth that was used for capturing fairly hard prey, and the presence of turtle bones as gut contents lends support to the hypothesis that Prognathodon was adapted to crush through hard-shelled prey. The teeth are, however, quite high relative to the size of the skull, which suggests that they were used for impaling prey rather than for crushing or grasping it. Many of the fully erupted teeth have crenulations on the carinae that produce a fine serration.

The shape of the preserved serrations are too different from those of Saurornitholestes for the marks to be the result of injuries incurred during intraspecific face biting behaviors. Although the right shape for Dromaeosaurus tooth serrations, the preserved marks are too coarse to have been left by that genus. Although a specific identification cannot be made, the most likely perpetrator would be a juvenile individual of one of the Dinosaur Park Formation's tyrannosaurids, like Gorgosaurus, Daspletosaurus, or Aublysodon. Jacobsen determined that all of the marks on the jawbone were left by the same animal because the serration marks all share the same morphology.

Tyrannosaurid teeth were used as holdfasts for pulling flesh off a body, so when a tyrannosaur pulled back on a piece of meat, the tension could cause a purely crack-like serration to spread through the tooth. However, the presence of the ampulla distributed these forces over a larger surface area, and lessened the risk of damage to the tooth under strain. The presence of incisions ending in voids has parallels in human engineering. Guitar makers use incisions ending in voids to, as Abler describes, "impart alternating regions of flexibility and rigidity" to wood they work.

This brought about the Model 1902 Military model which although inspired by military suggestions, was nonetheless primarily a commercial pistol. It eclipsed the sporting model in sales by about three to one. However, if one considers the production of the 1903 Pocket Hammer models as being just short barreled 1902 Sporting Models, which they basically were, then the 1902 Military comes in second-best. The 1902 "Military" model was introduced with a new style of front serration, a densely checkered area on the front of the slide immediately discernible from the 1902 Sporting Model's plunge serrations.

Eight variations of known Hamada pistols exist with slight differences between them with all known pistols containing serial numbers between 2,214 and 2,959. The narrowness of the range may be attributed to the small number of pistol assigned to the Pacific Theater, where U.S. soldiers collected souvenirs. The number of serration made on the rear slide increased from six to seven between variation one and two, being reduced back to six serrations with variation three. The grip made of walnut and had a checked pattern with the border design, and lanyard loop being simplified between pistol variation three and four.

The equalizing pulses and the serration of the vertical sync pulse were necessary because of the limitations of the extant TV receiver video/sync separation technology, thought to be necessary because the sync was transmitted in band with the video, although at a quite different DC level. The early TV sets did not possess a DC restorer circuit, hence the need for this level of complexity. In-studio monitors were provided with separate horizontal and vertical sync, not composite synch and certainly not in-band synch (possibly excepting early color TV monitors, which were often driven from the output of the station's colorplexer).

A section of hydathode in the leaf of Primula sinensis (Brockhaus and Efron Encyclopedic Dictionary) A hydathode is a type of pore, commonly found in angiosperms, that secretes water through pores in the epidermis or leaf margin, typically at the tip of a marginal tooth or serration. Hydathodes occur in the leaves of submerged aquatic plants such as Ranunculus fluitans as well as herbaceous plants of drier habitats such as Campanula rotundifolia. They are connected to the plant vascular system by a vascular bundle. Hydathodes are commonly seen in water lettuce, water hyacinth, rose, balsam, and many other species.

Due to a close resemblance of the swimming legs, C. punctatum is assumed to have been similar in appearance to C. newlini. C. punctatum can be distinguished from C. newlini by the serration along the margin of the distal podomeres of C. punctatum being more pronounced. C. harleyi, from the Late Ludlow epoch, was described mainly based on specimens previously known (some having been reported by Salter as early as 1859) but previously referred to Eurypterus punctatus. Recognized by Kjellesvig-Waering as distinct, the species is named in honor of John Harley, one of the earliest collectors of eurypterid fossils in the region.

The pygidium is papillated, with two anal cirri twice as long as the dorsal cirri. Sphaerosyllis levantina and Sphaerosyllis minima are alike, by having serrated blades of falcigers throughout the body. S. minima, however has a stronger dorso-ventral gradation of the falcigers' blades. Sphaerosyllis capensis, Sphaerosyllis taylori, and Sphaerosyllis sandrae also show similarities with S. levantina, especially with regards to the shape and serration of the falcigers' blades, but S. capensis has all antennae positioned in line, and S. taylori shows no dorso-ventral gradation of the falciger blade length, while S. sandrae has smooth falcigerous blades posteriorly and parapodial glands with hyaline material.

Cephalopholis igarashiensis has a deep body with the depth of the body being greater than the length of the head, the standard length is 2.0 to 2.4 times the depth of the body. The dorsal profile of the head is straight or marginally concave to beyond the eye while the nape is distinctly convex. The preopercleis rounded and the edges have fine serrations although those on the ventral margin are slightly less fine giving it a more irregular appearance but the serration remain enclosed within the skin. The dorsal fin contains 9 spines and 14 soft rays while the anal fin has 3 spines and 9 soft rays.

Two prominent ridges descend from each serration towards the front down the sides of the tooth. No roots are preserved, but the rounded surface of the lower side of the tooth suggests they may have been resorbed, which would indicate that the tooth is deciduous. Krause and colleagues suggested that the tooth may have been the frontmost premolar, whether deciduous or permanent. However, Kielan-Jaworowska and Bonaparte wrote that this tooth does not match the partial jaw MACN Pv-RN 975, which has no alveoli in front of p4, and Pascual and colleagues agreed in 1999 that the tooth probably does not belong to Ferugliotherium.

Notch was discovered in a mutant Drosophila in March 1913 in the lab of Thomas Hunt Morgan. This mutant emerged after several generations of crossing out and back-crossing beaded winged flies with wild type flies and was first characterized by John S. Dexter. The most frequently observed phenotype in Notch mutant flies is the appearance of a concave serration at the most distal end of the wings, for which the gene is named, accompanied by the absence of marginal bristles. This mutant was found to be a sex-linked dominant on the X chromosome that could only be observed in heterozygous females as it was lethal in males and homozygous females.

The genealogy of sickles with serrated edge reaches back to the Stone Age, when individual pieces of flint were first attached to a “blade body” of wood or bone. (The majority among the well-documented specimens made later of bronze are smooth-edged.) Nevertheless, teeth have been cut with hand-held chisels into iron, and later steel-bladed sickles for a long time. In many countries on the African continent, Central and South America as well as the Near, Middle and Far East this is still the case in the regions within these large geographies where the traditional village blacksmith remains alive and well. England appears to have been the first to develop the industrial process of serration-making.

The name Anopterus comes from the Ancient Greek words ano (upwards) and pteron (wing), referring to its characteristic winged seeds, while glandulosus refers to the glandular tips present at the end of each leaf serration. The signature 'Labill' often appears after the Latin name of this species as it was first described by Jacques Labillardière in 1805. It is one of two Tasmanian plants in the ancient Gondwanan family Escalloniaceae, the other plant being Tetracarpaea tasmanica. Anopterus is an endemic Australian genus and Anopterus glandulosus is one of two species in the genus. The other species, Anopterus macleayanus or ‘Queensland Laurel’/ ‘Macleay Laurel’ is found in subtropical, warm and cool temperate forests near the coast in New South Wales and Queensland.

Note the sawtooth design on the landing gear door and access panels Stealth is a key aspect of the F-35s design, and radar cross-section (RCS) is minimized through careful shaping of the airframe and the use of radar-absorbent materials (RAM); visible measures to reduce RCS include alignment of edges, serration of skin panels, and the masking of the engine face and turbine. Additionally, the F-35's diverterless supersonic inlet (DSI) uses a compression bump and forward-swept cowl rather than a splitter gap or bleed system to divert the boundary layer away from the inlet duct, eliminating the diverter cavity and further reducing radar signature."Fast History: Lockheed's Diverterless Supersonic Inlet Testbed F-16" aviationintel.com, 13 January 2013"F-35 Joint Strike Fighter (JSF) Lightning II".

Anguanax is a medium size carnivorous basal pliosaurid, at an estimated body length of about 3–4 m based on the holotype. Its general body proportions are similar to those of other early pliosaurid, for example the well preserved Peloneustes. Anguanax fed on soft or small- bodied prey in the upper pelagic zone of its environment, as suggested by its moderately expanded side-facing eye sockets, the gracile and relatively long lower jaw, and the small, slender, and slightly curved teeth with fine serration. Anguanax possesses two unique traits among other plesiosaurians including a projection on the palpebral placed at midheight of the front- facing margin of the eye socket; and a posteroventral process of coracoid developed as a distinct trapezoid that does not reach the glenoid level from the side, and with a straight margin directed back and to the side from its back facing position.

Oxford dress shoes The brogue (derived from the Gaelic (Irish), (Scottish) "shoe") is a style of low-heeled shoe or boot traditionally characterised by multiple-piece, sturdy leather uppers with decorative perforations (or "broguing") and serration along the pieces' visible edges. Brogues were traditionally considered to be outdoor or country footwear not otherwise appropriate for casual or business occasions, but brogues are now considered appropriate in most contexts. Brogues are most commonly found in one of four toe cap styles (full or "wingtip", semi-, quarter and longwing) and four closure styles (Oxford, Derby, ghillie, and monk). Today, in addition to their typical form of sturdy leather shoes or boots, brogues may also take the form of business dress shoes, sneakers, high-heeled women's shoes, or any other shoe form that utilises or evokes the multi-piece construction and perforated, serrated piece edges characteristic of brogues.
