Bullwhip
A bullwhip is a single-tailed whip, usually made of braided leather or nylon, designed as a tool for working with livestock or competition. Bullwhips are pastoral tools, traditionally used to control livestock in open country. A bullwhip's length, flexibility, and tapered design allows it to be thrown in such a way that, toward the end of the throw, part of the whip exceeds the speed of sound—thereby creating a small sonic boom. The bullwhip was rarely, if ever, used to strike cattle, as this could inflict damage to the animal. The bullwhip should not be confused with the stockwhip, an Australian whip also used to control livestock but having a somewhat different structure. History The origins of the bullwhip are also a matter for debate and, given the perishable nature of leather, are likely to remain so. Difficulties in tracing its development also arise from regional and national variations in nomenclature. There are claims that it was developed in South America where, ...

Bullwhip Effect
The bullwhip effect is a supply chain phenomenon where orders to suppliers tend to have a larger variability than sales to buyers, which results in an amplified demand variability upstream. In part, this results in increasing swings in inventory in response to shifts in consumer demand as one moves further up the supply chain. The concept first appeared in Jay Forrester's ''Industrial Dynamics'' (1961) and thus it is also known as the Forrester effect. It has been described as “the observed propensity for material orders to be more variable than demand signals and for this variability to increase the further upstream a company is in a supply chain”. Science at Stanford University helped incorporate the concept into supply chain vernacular using a story about Volvo. Suffering a glut in green cars, sales and marketing developed a program to sell the excess inventory. While successful in generating the desired market pull, manufacturing did not know about the promotional plans. In ...

Whip (implement)
A whip is a tool or weapon designed to strike humans or other animals to exert control through pain compliance or fear of pain. They can also be used without inflicting pain, for audiovisual cues, such as in equestrianism. They are generally either a firm stick designed for direct contact, or a flexible line requiring a specialized swing. The former is easier and more precise, the latter offers longer reach and greater force. A hunting whip combines a firm stick (the stock or handle) with a flexible line (the lash or thong). Whips such as the "cat o' nine tails" and knout are specifically developed for flagellation as a means of inflicting corporal punishment or torture on human targets. Certain religious practices and BDSM activities involve the self-use of whips or the use of whips between consenting partners. Misuse on non-humans may be considered animal cruelty, and misuse on humans may be viewed as assault. Use Whips are generally used on animals to provide directional g ...

Whip Cracking
Whipcracking is the act of producing a cracking sound through the use of a whip. Used during livestock driving and horse riding, it has also become an art. A rhythmic whipcracking belongs to the traditional culture among various Germanic peoples of Bavaria ('' Goaßlschnalzen''), various Alpine areas (''Aperschnalzen''), Austria, and Hungary (Ostorozás). Today it is a performing art, a part of rodeo show in United States, a competitive sport in Australia and increasingly popular in the United Kingdom, where it crosses boundaries of sport, hobby and performance. Physics The crack a whip makes is produced when a section of the whip moves faster than the speed of sound creating a small sonic boom. The creation of the sonic boom was confirmed in 1958 by analyzing the high-speed shadow photography taken in 1927.American Physical Society (2002) Whip Cracking Mystery Explained'' 26 May 2002 Recently, an additional, purely geometrical factor was recognized: the tip of the whip moves ...

Sonic Boom
A sonic boom is a sound associated with shock waves created when an object travels through the air faster than the speed of sound. Sonic booms generate enormous amounts of sound energy, sounding similar to an explosion or a thunderclap to the human ear. A decibel is the primary unit measurement of sound. "A thunderclap is incredibly loud, producing levels between 100 and 120 dBA (Decibel, decibels A)- the equivalent of standing near a jet during take-off." The crack of a supersonic bullet passing overhead or the crack of a bullwhip are examples of a sonic boom in miniature. Sonic booms due to large supersonic aircraft can be particularly loud and startling, tend to awaken people, and may cause minor damage to some structures. This led to prohibition of routine supersonic flight overland. Although they cannot be completely prevented, research suggests that with careful shaping of the vehicle, the nuisance due to the sonic booms may be reduced to the point that overland super ...

Paracord
Parachute cord (also paracord or 550 cord when referring to type-III paracord) is a lightweight nylon kernmantle rope originally used in the suspension lines of parachutes. This cord is now used as a general purpose utility cord. This versatile cord was used by astronauts during the 82nd Space Shuttle mission to repair the Hubble Space Telescope. The braided sheath is usually made up of 32 interwoven strands, giving it a relatively smooth texture. The all-nylon construction makes paracord somewhat elastic. Current technical standards for the manufacture of cord for use in parachutes are published by the Parachute Industry Association. The now inactivated US military standard MIL-C-5040H required the material to be nylon. Similar styles of cord are manufactured with other materials such as polyester. Usage Historically associated with airborne units and divisions, paracord is not used as cordage for modern "square" parachutes. However, it continues to be used by many militar ...

Urumi
Urumi (Malayalam: ''uṟumi''; Sinhalese: ''ethunu kaduwa''; Hindi: ''āra'') is a sword with a flexible, whip-like blade, originating in modern-day Kerala in the Indian subcontinent. It is thought to have existed from as early as the Sangam period. It is treated as a steel whip and therefore requires prior knowledge of that weapon as well as the sword. For this reason, the urumi is always taught last in Indian martial arts such as Kalaripayattu. The word ''urumi'' is used to refer to the weapon in Malayalam. In Kerala, it is also called ''chuttuval'', from the Malayalam words for "coiling," or "spinning,"(''chuttu'') and "sword" (''val''). Alternatively, Tamil names for the weapon are ''surul katti'' (coiling knife), ''surul val'' (coiling sword) and ''surul pattakatti'' (coiling machete). Anatomy The urumi hilt is constructed from iron or brass and is identical to that of the ''talwar'', complete with a crossguard and frequently a slender knucklebow. The typical handle is te ...

Indonesian Martial Arts
Indonesian martial arts includes a variety of fighting systems native to or developed in the archipelago of Indonesia, both the age-old traditional arts, and the more recently developed hybrid combatives. In the Indonesian language the term ''bela-diri'' (lit. self-defense) is used to mean martial art, and in essence the Indonesian fighting arts are meant as one's defence against perceived threat and assault. Other than physical training, they often include spiritual aspects to cultivate inner strength, inner peace and higher psychological ends. Today, Indonesian fighting styles are synonymous with pencak silat, a term coined for the martial arts of the Indonesian archipelago. Nevertheless, a number of fighting arts in Indonesia are not included within the category of silat. Western misconception links silat with "jungle tribes" but in actuality, pencak silat was neither created nor traditionally practised by Indonesia's tribal inhabitants, many of whom have unique martial arts ...

Sjambok
The sjambok () or litupa is a heavy leather whip. It is traditionally made from an adult hippopotamus or rhinoceros hide, but is also commonly made out of plastic. A strip of the animal's hide is cut and carved into a strip long, tapering from about thick at the handle to about at the tip. This strip is then rolled until reaching a tapered-cylindrical form. The resulting whip is both flexible and durable. A plastic version was made for the apartheid era South African Police, and used for riot control. Peter Hathaway Capstick describes a sjambok as a short swordlike whip made from rhino pizzle leather that could lay a man open like a straight razor. The sjambok was heavily used by the Voortrekkers driving their oxen while migrating from the Cape of Good Hope, and remains in use by herdsmen to drive cattle. They are widely available in South Africa from informal traders to regular stores from a variety of materials, lengths and thicknesses. Use by police In South Africa, us ...

Edmonton Journal
The ''Edmonton Journal'' is a daily newspaper in Edmonton, Alberta. It is part of the Postmedia Network. History The ''Journal'' was founded in 1903 by three local businessmen — John Macpherson, Arthur Moore and J.W. Cunningham — as a rival to Alberta's first newspaper, the 23-year-old ''Edmonton Bulletin''. Within a week, the ''Journal'' took over another newspaper, ''The Edmonton Post'', and established an editorial policy supporting the Conservative Party of Canada (historical), Conservative Party against the ''Bulletins stance for the Liberal Party of Canada, Liberal Party. In 1912, the ''Journal'' was sold to the William Southam, Southam family. It remained under Southam ownership until 1996, when it was acquired by Hollinger International. The ''Journal'' was subsequently sold to Canwest in 2000, and finally came under its current ownership, Postmedia Network Inc., in 2010.

Wolf
The wolf (''Canis lupus''; : wolves), also known as the gray wolf or grey wolf, is a large canine native to Eurasia and North America. More than thirty subspecies of ''Canis lupus'' have been recognized, and gray wolves, as popularly understood, comprise wild subspecies. The wolf is the largest extant member of the family Canidae. It is also distinguished from other ''Canis'' species by its less pointed ears and muzzle, as well as a shorter torso and a longer tail. The wolf is nonetheless related closely enough to smaller ''Canis'' species, such as the coyote and the golden jackal, to produce fertile hybrids with them. The banded fur of a wolf is usually mottled white, brown, gray, and black, although subspecies in the arctic region may be nearly all white. Of all members of the genus ''Canis'', the wolf is most specialized for cooperative game hunting as demonstrated by its physical adaptations to tackling large prey, its more social nature, and its highly advanc ...
