Headbutting
A headbutt is a targeted strike (attack), strike with the head, typically (when intentional) involving the use of robust parts of the headbutter's Human cranium, cranium as the area of impact. The most effective headbutts strike the most sensitive areas of an opponent, such as the Human nose, nose, using the stronger bones in the forehead (frontal bone) or the back of the skull (occipital bone, occipital or parietal bone). Mechanics Headbutts can be used from close range such as from the grappling position#Stand-up grappling position, clinch, or on the grappling position#Ground grappling position, ground. They are typically applied to the head of the opponent, since the head is often a readily available target and has several sensitive areas, but can be delivered to any part of the body. It is considered a quick, very effective but risky maneuver, as a misplaced strike can also cause injury to the person delivering the headbutt. An effective headbutt can be performed with a fo ...

Boys From The Blackstuff
''Boys from the Blackstuff'' is a British drama television series of five episodes, originally transmitted from 10 October to 7 November 1982 on BBC2. The serial was written by Liverpudlian playwright Alan Bleasdale, as a sequel to a television play titled ''The Black Stuff''. The British Film Institute described it as a "seminal drama series... a warm, humorous but ultimately tragic look at the way economics affect ordinary people… TV's most complete dramatic response to the Thatcher era and as a lament to the end of a male, working class British culture." ''The Black Stuff'' The television play ''The Black Stuff'' was originally written by Bleasdale and directed by Jim Goddard for BBC1's ''Play for Today'' anthology series in 1978. After filming however, the play was not transmitted until 2 January 1980.

Strike (attack)
A strike is a directed physical attack with either a part of the human body or with an inanimate object (such as a weapon) intended to cause blunt trauma or penetrating trauma upon an opponent. There are many different varieties of strikes. A strike with the hand closed into a fist is called a punch, a strike with the leg or foot is referred to as a kick and a strike with the head is called a headbutt. There are also other variations employed in martial arts and combat sports. "Buffet" or "beat" refer to repeatedly and violently striking an opponent; this is also commonly referred to as a combination, or combo, especially in boxing or fighting video games. Usage Strikes are the key focus of several sports and arts, including boxing, savate, karate, Muay Lao, taekwondo and wing chun. Some martial arts also use the fingertips, wrists, forearms, shoulders, back and hips to strike an opponent as well as the more conventional fists, palms, elbows, knees and feet that are commo ...

Capoeira
Capoeira () is an Afro-Brazilian martial art that combines elements of dance, acrobatics, music and spirituality. Born of the melting pot of enslaved Africans, Indigenous Brazilians and Portuguese influences at the beginning of the 16th century, capoeira is a constantly evolving art form. It is known for its acrobatic and complex maneuvers, often involving hands on the ground and inverted kicks. It emphasizes flowing movements rather than fixed stances; the '' ginga'', a rocking step, is usually the focal point of the technique. Although debated, the most widely accepted origin of the word ''capoeira'' comes from the Tupi words ''ka'a'' ("forest") ''paũ'' ("round"), referring to the areas of low vegetation in the Brazilian interior where fugitive slaves would hide. A practitioner of the art is called a capoeirista (). Though often said to be a martial art disguised as a dance, capoeira served not only as a form of self defence, but also as a way to maintain spirituality and cu ...

Pheromones
A pheromone () is a secreted or excreted chemical factor that triggers a social response in members of the same species. Pheromones are chemicals capable of acting like hormones outside the body of the secreting individual, to affect the behavior of the receiving individuals. There are ''alarm pheromones'', ''food trail pheromones'', ''sex pheromones'', and many others that affect behavior or physiology. Pheromones are used by many organisms, from basic unicellular prokaryotes to complex multicellular eukaryotes. Their use among insects has been particularly well documented. In addition, some vertebrates, plants and ciliates communicate by using pheromones. The ecological functions and evolution of pheromones are a major topic of research in the field of chemical ecology. Background The portmanteau word "pheromone" was coined by Peter Karlson and Martin Lüscher in 1959, based on the Greek φερω ''pheroo'' ('I carry') and ὁρμων ''hormon'' ('stimulating'). Pheromones ...

Scent Glands
Scent gland are exocrine glands found in most mammals. They produce semi-viscous secretions which contain pheromones and other semiochemical compounds. These odor-messengers indicate information such as status, territorial marking, mood, and sexual behaviour. The odor may be subliminal—not consciously detectable. Though it is not their primary function, the salivary glands may also function as scent glands in some animals. In even-toed ungulates The even-toed ungulates (Artiodactyla) have many specialized skin glands, the secretions of which are involved in semiochemical communication. These glands include the sudoriferous glands (located on the forehead, between the antlers and eyes), the preorbital glands (extending from the medial canthus of each eye), the nasal glands (located inside the nostrils), the interdigital glands (located between the toes), the preputial gland (located inside the foreskin of the penis), the metatarsal glands (located outside of the hind legs), the ...

Hydraulic Ram
A hydraulic ram, or hydram, is a cyclic water pump powered by hydropower. It takes in water at one "hydraulic head" (pressure) and flow rate, and outputs water at a higher hydraulic head and lower flow rate. The device uses the water hammer effect to develop pressure that allows a portion of the input water that powers the pump to be lifted to a point higher than where the water originally started. The hydraulic ram is sometimes used in remote areas, where there is both a source of low-head hydropower and a need for pumping water to a destination higher in elevation than the source. In this situation, the ram is often useful, since it requires no outside source of power other than the kinetic energy of flowing water. History The Alhambra, built by Nasrid Sultan Ibn al-Ahmar of Granada beginning AD1238, used a hydram to raise water. Through a first reservoir, filled by a channel from the Darro River, water emptied via a large vertical channel into a second reservoir bene ...

Battering Ram
A battering ram is a siege engine that originated in ancient history, ancient times and was designed to break open the masonry walls of fortifications or splinter their wooden gates. In its simplest form, a battering ram is just a large, heavy log carried by several people and propelled with force against an obstacle; the ram would be sufficient to damage the target if the log were massive enough and/or it were moved quickly enough (that is, if it had enough momentum). Later rams encased the log in an arrow-proof, fire-resistant canopy mounted on wheels. Inside the canopy, the log was swung from suspensory chains or ropes. Rams proved effective weapons of war because at the time wall-building materials such as stone and brick were weak in Tension (physics), tension, and therefore prone to cracking when impacted with force. With repeated blows, the cracks would grow steadily until a hole was created. Eventually, a breach would appear in the fabric of the wall, enabling armed ...

Mouflon
The mouflon (''Ovis gmelini'') is a wild sheep native to Cyprus, the Caspian Sea, Caspian region from eastern Turkey, Armenia, Azerbaijan, and Iran. It is thought to be the ancestor of all modern domestic sheep breeds. Taxonomy ''Ovis gmelini'' was the scientific name proposed by Edward Blyth in 1841 for wild sheep in the Middle East. In the 19th and 20th centuries, several wild sheep were described that are considered mouflon subspecies today: * ''Ovis ophion'' by Blyth in 1841 for wild sheep in Cyprus; * ''Ovis laristanica'' by Nikolai Nasonov in 1909 for wild sheep in Lar, Iran, Lar in southern Iran; * ''Ovis orientalis isphahanica'' by Nasonov in 1910 for wild sheep in the Zagros Mountains. Subspecies Five mouflon subspecies of are distinguished by Mammal Species of the World, MSW3: * Armenian mouflon (Armenian red sheep), ''O. g. gmelini'' : nominate subspecies; native to northwestern Iran, Armenia, and Azerbaijan. It has been introduced to Texas in the U.S. * Esfahan mou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
