Long bone

The long bones are those that are longer than they are wide. They are one of five types of bones: long, short, flat, irregular and sesamoid. Long bones, especially the femur and tibia, are subjected to most of the load during daily activities and they are crucial for skeletal mobility. They grow primarily by elongation of the diaphysis, with an epiphysis at each end of the growing bone. The ends of epiphyses are covered with hyaline cartilage ("articular cartilage"). The longitudinal growth of long bones is a result of endochondral ossification at the epiphyseal plate. Bone growth in length is stimulated by the production of growth hormone (GH), a secretion of the anterior lobe of the pituitary gland.

The long bones include the femora, tibiae, and fibulae of the legs; the humeri, radii, and ulnae of the arms; metacarpals and metatarsals of the hands and feet, the phalanges of the fingers and toes, and the clavicles or collar bones. The long bones of the human leg comprise nearly half of adult height. The other primary skeletal component of height are the vertebrae and skull.

Bone

A bone is a rigid organ that constitutes part of the vertebral skeleton. Bones support and protect the various organs of the body, produce red and white blood cells, store minerals and also enable mobility. Bone tissue is a type of dense connective tissue. Bones come in a variety of shapes and sizes and have a complex internal and external structure. They are lightweight yet strong and hard, and serve multiple functions. Mineralized osseous tissue, or bone tissue, is of two types, cortical and cancellous, and gives a bone rigidity and a coral-like three-dimensional internal structure. Other types of tissue found in bones include marrow, endosteum, periosteum, nerves, blood vessels and cartilage.

Bone is an active tissue composed of different types of bone cells. Osteoblasts are involved in the creation and mineralisation of bone; osteocytes and osteoclasts are involved in the reabsorption of bone tissue. The mineralised matrix of bone tissue has an organic component mainly of collagen and an inorganic component of bone mineral made up of various salts.

Bône (département)

Bône is a former French département in Algeria which existed between 1955 and 1962.

Considered as a French province, Algeria was departmentalised on 9 December 1848. Three civil zones (départements) replaced the three beyliks into which the Ottoman former rulers had divided the territory. The easternmost of the three original Algerian departments was called Constantine. For over a century the town of Annaba, known at that time as Bône (and in classical times as Hippo), was a sub-prefecture in the département of Constantine: this changed in 1955.

On 7 August 1955 the eastern extremity of the former département of Constantine was split off and became the separate département of Bône. This administrative reorganisation was a response to the rapid population increase experienced across the territory, especially during the preceding decade.

The new coastal département of Bône covered an area of 25,367 km²: a population of 730,594 was recorded. The department comprised five sub-prefectures: these were La Calle, Clairfontaine, Guelma, Souk Ahras and Tébessa. A final but temporary change took place between 17 March 1958 and 7 November 1959, during which time the Tébessa sub-prefectures was transferred to the département of Batna.

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.
