Head louse

The head louse (Pediculus humanus capitis) is an obligate ectoparasite of humans that causes pediculosis capitis. Head lice are wingless insects spending their entire life on the human scalp and feeding exclusively on human blood.Humans are the only known hosts of this specific parasite, while chimpanzees host a closely related species, Pediculus schaeffi. Other species of lice infest most orders of mammals and all orders of birds, as well as other parts of the human body.

Lice differ from other hematophagic ectoparasites such as fleas in spending their entire life cycle on a host. Head lice cannot fly, and their short stumpy legs render them incapable of jumping, or even walking efficiently on flat surfaces.

The non-disease-carrying head louse differs from the related disease-carrying body louse (Pediculus humanus humanus) in preferring to attach eggs to scalp hair rather than to clothing. The two subspecies are morphologically almost identical but do not normally interbreed, although they will do so in laboratory conditions. From genetic studies, they are thought to have diverged as subspecies about 30,000–110,000 years ago, when many humans began to wear a significant amount of clothing. A much more distantly related species of hair-clinging louse, the pubic or crab louse (Pthirus pubis), also infests humans. It is visually different from the other two species and is much closer in appearance to the lice which infest other primates. Lice infestation of any part of the body is known as pediculosis.

Sheepshead (game)

Sheepshead or Sheephead is a trick-taking card game related to the Skat family of games. It is the Americanized version of a card game that originated in Central Europe in the late 18th century under the German name Schafkopf. Sheepshead is most commonly played by five players, but variants exist to allow for two to eight players. There are also many other variants to the game rules, and many slang terms used with the game.

Although Schafkopf literally means "sheepshead," it has nothing to do with sheep; the term probably was derived and translated incorrectly from Middle High German and referred to playing cards on a barrel head (from kopf, meaning head, and Schaff, meaning a barrel).

In the United States, sheepshead is most commonly played in Wisconsin as well as the German counties in Southern Indiana, which has large German-American populations, and on the internet. Numerous tournaments are held throughout Wisconsin during the year, with the largest tournament being the "Nationals", held annually in the Wisconsin Dells during a weekend in September, October or November, and mini-tournaments held hourly throughout Germanfest in Milwaukee during the last weekend of each July.

Long (finance)

In finance, a long position in a security, such as a stock or a bond, or equivalently to be long in a security, means the holder of the position owns the security and will profit if the price of the security goes up. Going long is the more conventional practice of investing and is contrasted with going short. An options investor goes long on the underlying instrument by buying call options or writing put options on it.

In contrast, a short position in a futures contract or similar derivative means that the holder of the position will profit if the price of the futures contract or derivative goes down.

Song

A song is a single (and often standalone) work of music intended to be sung by the human voice with distinct and fixed pitches and patterns using sound and silence and a variety of forms that often include the repetition of sections. Written words created specifically for music or for which music is specifically created, are called lyrics. If a pre-existing poem is set to composed music in classical music it is an art song. Songs that are sung on repeated pitches without distinct contours and patterns that rise and fall are called chants. Songs in a simple style that are learned informally are often referred to as folk songs. Songs that are composed for professional singers are called popular songs. These songs, which have broad appeal, are often composed by professional songwriters, composers and lyricists. Art songs are composed by trained classical composers for concert performances. Songs are performed live and recorded. Songs may also appear in plays, musical theatre, stage shows of any form, and within operas.

Song (airline)

Song, LLC was a low-cost air service within an airline brand owned and operated by Delta Air Lines from 2003 to 2006.

Song's main focus was on leisure traffic between the northeastern United States and Florida, a market where it competed with JetBlue Airways. It also operated flights between Florida and the West Coast, and from the Northeast to the west coast.

Song's aircraft were fitted with leather seats and free personal entertainment systems at every seat, with audio MP3 programmable selections, trivia games that could be played against other passengers, a flight tracker, and satellite television (provided by the DISH Network). Song offered free beverages, but charged for meals and liquor. Both brand-name snack boxes and healthy organic meals were offered. The flight safety instructions were sung or otherwise artistically interpreted, depending on the cabin crew. In addition to crew uniforms designed by Kate Spade, customized cocktails created by nightlife impresario Rande Gerber and an in-flight exercise program designed by New York City fitness guru David Barton, the airline created its own distinct mark in the industry. The Song brand was placed on more than 200 flights a day which carried over ten million passengers.
