Siyah Bir Veda Öpücügü
A composite bow is a traditional bow made from horn, wood, and sinew laminated together, a form of laminated bow. The horn is on the belly, facing the archer, and sinew on the outer side of a wooden core. When the bow is drawn, the sinew (stretched on the outside) and horn (compressed on the inside) store more energy than wood for the same length of bow. The strength can be made similar to that of all-wood "self" bows, with similar draw-length and therefore a similar amount of energy delivered to the arrow from a much shorter bow. However, making a composite bow requires more varieties of material than a self bow, its construction takes much more time, and the finished bow is more sensitive to moisture. Archaeological finds and art indicate composite bows have existed since the second millennium BCE, but their history is not well recorded, being developed by cultures without a written tradition. They originated among Asiatic pastoralists who used them as daily necessities, clas ...

The Odyssey
The ''Odyssey'' (; grc, Ὀδύσσεια, Odýsseia, ) is one of two major ancient Greek epic poems attributed to Homer. It is one of the oldest extant works of literature still widely read by modern audiences. As with the ''Iliad'', the poem is divided into 24 books. It follows the Greek hero Odysseus, king of Ithaca, and his journey home after the Trojan War. After the war, which lasted ten years, his journey lasted for ten additional years, during which time he encountered many perils and all his crew mates were killed. In his absence, Odysseus was assumed dead, and his wife Penelope and son Telemachus had to contend with a group of unruly suitors who were competing for Penelope's hand in marriage. The ''Odyssey'' was originally composed in Homeric Greek in around the 8th or 7th century BCE and, by the mid-6th century BCE, had become part of the Greek literary canon. In antiquity, Homer's authorship of the poem was not questioned, but contemporary scholarship predom ...

Bow String
A bowstring joins the two ends of the bow stave and launches the arrow. Desirable properties include light weight, strength, resistance to abrasion, and resistance to water. Mass has most effect at the center of the string; of extra mass in the middle of the string slows the arrow about as much as at the ends. String forms Most bowstrings may be described as either simple, reverse-twisted, or looped. Simple strings may be made of any fiber, twisted into a single cord. Such strings have been used in many parts of the world and are still effective and fairly quick to make. However, they tend to be weaker for their weight, and they may also come apart if not kept constantly under tension. They are normally secured to the bow by a knot/round turn and two half-hitches at each end. Reverse-twisted strings are traditional in Europe and North America for most natural materials. Linen and hemp fiber have been widely used. The form is also used for modern materials. A reverse-twisted ...

Gas Bladder
The swim bladder, gas bladder, fish maw, or air bladder is an internal gas-filled organ that contributes to the ability of many bony fish (but not cartilaginous fish) to control their buoyancy, and thus to stay at their current water depth without having to expend energy in swimming. Also, the dorsal position of the swim bladder means the center of mass is below the center of volume, allowing it to act as a stabilizing agent. Additionally, the swim bladder functions as a resonating chamber, to produce or receive sound. The swim bladder is evolutionarily homologous to the lungs. Charles Darwin remarked upon this in ''On the Origin of Species''.Darwin, Charles (1859''Origin of Species''Page 190, reprinted 1872 by D. Appleton. Darwin reasoned that the lung in air-breathing vertebrates had derived from a more primitive swim bladder. In the embryonic stages, some species, such as redlip blenny, have lost the swim bladder again, mostly bottom dwellers like the weather fish. ...

Isinglass
Isinglass () is a substance obtained from the dried swim bladders of fish. It is a form of collagen used mainly for the clarification or fining of some beer and wine. It can also be cooked into a paste for specialised gluing purposes. The English word origin is from the obsolete Dutch ''huizenblaas'' – ''huizen'' is a kind of sturgeon, and ''blaas'' is a bladder, or German ''Hausenblase'', meaning essentially the same. Although originally made exclusively from sturgeon, especially beluga, in 1795 an invention by William Murdoch facilitated a cheap substitute using cod. This was extensively used in Britain in place of Russian isinglass, and in the US hake was important. In modern British brewing all commercial isinglass products are blends of material from a limited range of tropical fish. The bladders, once removed from the fish, processed, and dried, are formed into various shapes for use. Foods and drinks Before the inexpensive production of gelatin and other compe ...

Hide Glue
Animal glue is an adhesive that is created by prolonged boiling of animal connective tissue in a process called rendering. In addition to being used as an adhesive it is used for coating and sizing, in decorative composition ornaments, and as a clarifying agent. These protein colloid glues are formed through hydrolysis of the collagen from skins, bones, tendons, and other tissues, similar to gelatin. The word ''collagen'' itself derives from Greek (), meaning 'glue'. These proteins form a molecular bond with the glued object. Conventionally, keratin glues, while made from animal parts like horns and hooves, are not considered animal glues as they are not collagen glues. Stereotypically, the animal in question is a horse, and horses that are put down are often said to have been "sent to the glue factory". However, other animals are also used, including cattle, rabbits and fish. History Early uses Animal glue has existed since ancient times, although its usage was not widespr ...

Ungulate
Ungulates ( ) are members of the diverse clade Ungulata which primarily consists of large mammals with hooves. These include odd-toed ungulates such as horses, rhinoceroses, and tapirs; and even-toed ungulates such as cattle, pigs, giraffes, camels, sheep, deer, and hippopotamuses. Cetaceans such as whales, dolphins, and porpoises are also classified as even-toed ungulates, although they do not have hooves. Most terrestrial ungulates use the hoofed tips of their toes to support their body weight while standing or moving. The term means, roughly, "being hoofed" or "hoofed animal". As a descriptive term, "ungulate" normally excludes cetaceans as they do not possess most of the typical morphological characteristics of other ungulates, but recent discoveries indicate that they were also descended from early artiodactyls. Ungulates are typically herbivorous and many employ specialized gut bacteria to allow them to digest cellulose. Some modern species, such as pigs, are omnivorous, ...

Hungarian Grey Cattle
The Hungarian Grey ( hu, Magyar Szürke, italic=no), also known as the Hungarian Grey Steppe, is a Hungarian breed of beef cattle. It belongs to the group of Podolic cattle and is characterised by long lyre-shaped horns and a pale grey coat. It is well adapted to extensive pasture systems and was formerly raised in very large numbers in the Hungarian puszta. In the twentieth century it came close to extinction, but numbers have since risen. History The origins of the Hungarian Grey are unknown. It was formerly accepted that it had arrived in the ninth century with the Magyars who came from the east, took the Carpathian Basin and settled there; this theory is not consistent with the archaeological record. It has also been suggested at various times that it was introduced in some later migration, possibly by Cumanian or Pecheneg peoples; that it was brought from the south by refugees from the Balkans; or that it came from the Italian peninsula, acquired either by raiding in ...

Ibex
An ibex (plural ibex, ibexes or ibices) is any of several species of wild goat (genus ''Capra''), distinguished by the male's large recurved horns, which are transversely ridged in front. Ibex are found in Eurasia, North Africa and East Africa. The name ''ibex'' comes from Latin, borrowed from Iberian or Aquitanian, akin to Old Spanish ''bezerro'' "bull", modern Spanish ''becerro'' "yearling". Ranging in height from and weighing , ibex can live 20 years. Two closely related varieties of goats found in the wild are not usually called ibex: the markhor and the feral goat. A male ibex is referred to as a buck, a female is a doe, and young juveniles are called kids. An ibex buck is commonly larger and heavier than a doe. The most noticeable difference between the sexes is the larger size of a buck's horns. The doe grows a pair of smaller, thinner horns which develop considerably more slowly than those of a buck. The ibex's horns appear at birth and continue to grow through the r ...

Oryx
''Oryx'' is a genus consisting of four large antelope species called oryxes. Their pelage is pale with contrasting dark markings in the face and on the legs, and their long horns are almost straight. The exception is the scimitar oryx, which lacks dark markings on the legs, only has faint dark markings on the head, has an ochre neck, and has horns that are clearly decurved. The Arabian oryx was only saved from extinction through a captive-breeding program and reintroduction to the wild. The scimitar oryx, which is now listed as extinct in the wild, also relies on a captive-breeding program for its survival.Database entry includes justification for why this species is listed as extinct in the wild. Etymology The term "oryx" comes from the Greek word ὄρυξ, ''óryx'', for a type of antelope. The Greek plural form is ''óryges'', although "oryxes" has been established in English. Herodotus mentions a type of gazelle in Libya called ὄρυς, ''orus'', probably related to ...

Gemsbok
The gemsbok or South African oryx (''Oryx gazella'') is a large antelope in the genus ''Oryx''. It is native to the extremely dry, arid regions of Southern Africa; notably, the Kalahari Desert. Some authorities formerly classified the East African oryx, or ''beisa'' oryx, as a subspecies. The gemsbok is depicted on the coat of arms of Namibia, where the current population of the species is estimated at 373,000 individuals. In the town of Oranjemund, resident gemsbok wander freely around the streets, taking advantage of the vegetation in the town, such as the grass in parks, road medians, and browsing on low branches of the many trees. Name The name ''gemsbok'' is from Afrikaans, which itself is from the Dutch word of the same spelling, meaning "male chamois", composed of (“chamois”) + (“buck, male goat”). The Dutch is further from German ("chamois"). Although some superficial similarities in appearance (especially in the facial pattern) are noticed, the chamois and t ...
