Rack unit

A rack unit, U or RU as a unit of measure describes the height of electronic equipment designed to mount in a 19-inch rack or a 23-inch rack. The 19 inches (482.60 mm) or 23 inches (584.20 mm) dimension reflects the width of the equipment mounting-frame in the rack including the frame; the width of the equipment that can be mounted inside the rack is less. One rack unit is 1.75 inches (44.45 mm) high.

While the rack unit describes the height (or number of units) for both 19-inch and 23-inch-wide racks, it is 19-inch-wide racks that are most commonly used for computer equipment, which is usually 17.25 in (438 mm) wide.

The 23 in racks are from the Western Electric 23-inch standard, with holes on 1-inch (25.4 mm) centers; it is still used in legacy ILEC/CLEC facilities.

The height of rack-mounted equipment is frequently described as a number in "U". For example, one rack unit is often referred to as "1U", 2 rack units as "2U" and so on.

Configurations

A typical full size rack is 42U, which means it holds just over 6 feet (1.8 m) of equipment, and a typical "half-height" rack would be 18–22U, or around 3 feet (0.91 m) high.

List of minor Buffy the Vampire Slayer characters

Buffy the Vampire Slayer is an American franchise which spans several media and genres. It began in 1992 with the film Buffy the Vampire Slayer, written by Joss Whedon and directed by Fran Rubel Kuzui, and was resurrected as the television series, Buffy the Vampire Slayer in 1997. The show's popularity caused it to spawn a multitude of Expanded Universe tie-in material such as comic books, novels, and video games, as well as a spin-off program entitled Angel. In 2007, four years after the television series' seventh and final season, Buffy the Vampire Slayer was officially continued in the comic book Season Eight. The following is a list of minor recurring characters who appear in the franchise.

Amanda

Amanda is a Potential Slayer who appears in Season Seven, played by Sarah Hagan. A Sunnydale High student and member of the swing choir, she first appears in the episode "Help" as part of the seemingly-random stream of students showing up at Buffy's guidance office. Amanda was sent to Buffy for beating up another student who was picking on her. In the later episode "Potential", it is revealed that Amanda is in fact a Potential Slayer, and she aptly slays a vampire who threatens her and Dawn. Afterwards, Amanda moves into the Summers' residence, where she trains and becomes friends with her fellow Potentials. In the final episode of the show, "Chosen", Amanda is activated as a Slayer along with the other Potentials and battles against an army of Turok-Han vampires. She is last seen falling to the ground dead after her neck was snapped by a Turok-Han. She was the first Potential to kill a vampire and the first one to kill a Turok-Han.

Rack (torture)

The rack is a torture device consisting of a rectangular, usually wooden frame, slightly raised from the ground, with a roller at one or both ends. The victim's ankles are fastened to one roller and the wrists are chained to the other. As the interrogation progresses, a handle and ratchet mechanism attached to the top roller are used to very gradually increase the tension on the chains, inducing excruciating pain. By means of pulleys and levers this roller could be rotated on its own axis, thus straining the ropes until the sufferer's joints were dislocated and eventually separated. Additionally, if muscle fibres are stretched excessively, they lose their ability to contract, rendering them ineffective.

One gruesome aspect of being stretched too far on the rack is the loud popping noises made by snapping cartilage, ligaments or bones. One powerful method for putting pressure upon prisoners was to force them to watch someone else being subjected to the rack. Confining the prisoner on the rack enabled further tortures to be simultaneously applied, typically including burning the flanks with hot torches or candles or using pincers made with specially roughened grips to tear out the nails of the fingers and toes. Usually, the victim's shoulders and hips would be separated and their elbows, knees, wrists, and ankles would be dislocated.

Rack (billiards)

A rack (sometimes known as a triangle) is the name given to a frame (usually wood, plastic or metal) used to organize billiard balls at the beginning of a game. Rack may also be used as a verb to describe the act of setting billiard balls in starting position in billiards games that make use of racks (usually, but not always, using a physical rack), as well as a noun to describe the balls in that starting position.

The most common shape of a physical rack is that of a triangle, with the ball pattern of 5-4-3-2-1. Racks are sometimes called simply "triangles" (most often by amateur shooters) based on the predominance of this form. Triangular-shaped racks are used for eight-ball, straight pool, one-pocket, bank pool, snooker and many other games. Although diamond-shaped racks, with an intended pattern of 1-2-3-2-1, are made for the game of nine-ball, the triangular rack is more often employed in nine ball as well.

Unit of alcohol

Units of alcohol are used in the United Kingdom (UK) as a measure to quantify the actual alcoholic content within a given volume of an alcoholic beverage, in order to provide guidance on total alcohol consumption.

A number of other countries (including Australia, Canada, New Zealand, and the US) use the concept of a "standard drink", the definition of which varies from country to country, for the same purpose. "Standard drinks" were referred to in the first UK guidelines (1984) that published "safe limits" for drinking, but these were replaced by references to "alcohol units" in the 1987 guidelines and the latter term has been used in all subsequent UK guidance.

One unit of alcohol (UK) is defined as 10 millilitres (8 grams) of pure alcohol. Typical drinks (i.e. typical quantities or servings of common alcoholic beverages) may contain 1–3 units of alcohol.

Containers of alcoholic beverages sold directly to UK consumers are normally labelled to indicate the number of units of alcohol in a typical serving of the beverage (optional) and in the full container (can or bottle), as well as information about responsible drinking. Additionally, the advent of smartphones has led to the creation of apps which report the number of units contained in an alcoholic drink.

Military organization

Military organization or military organisation is the structuring of the armed forces of a state so as to offer military capability required by the national defense policy. In some countries paramilitary forces are included in a nation's armed forces, though not considered military. Armed forces that are not a part of military or paramilitary organizations, such as insurgent forces, often mimic military organizations, or use ad hoc structures.

Military organization is hierarchical. The use of formalized ranks in a hierarchical structure came into widespread use with the Roman Army. In modern times, executive control, management and administration of military organization is typically undertaken by the government through a government department within the structure of public administration, often known as a Ministry of Defense, Department of Defense, or Department of War. These in turn manage Armed Services that themselves command combat, combat support and service support formations and units.
