Atomic mass unit

The unified atomic mass unit (symbol: u) or dalton (symbol: Da) is the standard unit that is used for indicating mass on an atomic or molecular scale (atomic mass). One unified atomic mass unit is approximately the mass of one nucleon (either a single proton or neutron) and is numerically equivalent to 1 g/mol. It is defined as one twelfth of the mass of an unbound neutral atom of carbon-12 in its nuclear and electronic ground state, and has a value of 6973166053904000000♠1.660539040(20)×10⁻²⁷ kg. The CIPM has categorised it as a non-SI unit accepted for use with the SI, and whose value in SI units must be obtained experimentally.

The amu without the "unified" prefix is technically an obsolete unit based on oxygen, which was replaced in 1961. However, some sources may still use the term "amu" but now define it in the same way as u (i.e., based on carbon-12). In this sense, most uses of the terms "atomic mass units" and "amu" today actually refer to unified atomic mass unit. For standardization a specific atomic nucleus (carbon-12 vs. oxygen-16) had to be chosen because the average mass of a nucleon depends on the count of the nucleons in the atomic nucleus due to mass defect. This is also why the mass of a proton (or neutron) by itself is more than (and not equal to) 1 u.

Dalton (crater)

Dalton is a lunar impact crater that is located near the western limb of the Moon's near side. It is attached to the eastern rim of the walled plain Einstein, with Balboa lying just to the north and Vasco da Gama due south. The rim of this crater is not heavily eroded, and the interior walls are terraced. The interior floor has a system of rilles that are generally concentric with the inner wall. There is a small crater near the southern inner wall, and another at the north face of the small central peak.

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.

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.
