Dan. may mean:
Dan is an old Scandinavian given name with disputed meaning. Dan is also a Hebrew given name, after Dan, the fifth son of Jacob with Bilhah and founder of the Israelite Tribe of Dan. It is also a given name or a nickname for people named Daniel.
Dan, or the acronym DAN may refer to the following:
Dan (Chinese: 旦; Wade–Giles: tan), is the general name for female roles in Chinese opera, often referring to leading roles. There are a few different kinds of dan in Chinese opera. The commonly seen ones are 'Guimen Dan', 'Hua Dan', 'Daoma Dan', 'Wu Dan', 'Lao Dan' and 'Cai Dan'. Each different kind of dan has its own unique characteristics.
Guimen Dan (闺门旦) is the role of the virtuous lady. It is also known as Qingyi (青衣)or Zhengdan (正旦). Qingyi means 'green robes' in Chinese, although the term traditionally extends to the colour black. This kind of dan used to wear black robes. Qing Yi are normally mature and sometimes married women. They may be rich or poor, young or of middle age, but they have to be mature women to fall under this category. Qingyi focus more on singing and they have little movement. They sing in a very high pitched and piercing voice which many people who do not appreciate Chinese opera find difficult to like. Opera schools in China have difficulty recruiting students for this kind of role, since it requires a good voice, good looks and a good height. The most famous qingyi of the last century was Mei Lanfang. Examples of Guimen Dan are Du Liniang (杜丽娘) from The Peony Pavilion (牡丹亭) and Wang Baochuan (王宝钏)from Wujiapo (武家坡).
Excess may refer to:
The limiting reagent (or limiting reactant) in a chemical reaction is the substance that is totally consumed when the chemical reaction is complete. The amount of product formed is limited by this reagent, since the reaction cannot continue without it. If one or more other reagents are present in excess of the quantities required to react with the limiting reagent, they are described as excess reagents or excess reactants.
The limiting reagent must be identified in order to calculate the percentage yield of a reaction, since the theoretical yield is defined as the amount of product obtained when the limiting reagent reacts completely. Given the balanced chemical equation, which describes the reaction, there are several equivalent ways to identify the limiting reagent and evaluate the excess quantities of other reagents.
This method is most useful when there are only two reactants. One reactant (A) is chosen, and the balanced chemical equation is used to determine the amount of the other reactant (B) necessary to react with A. If the amount of B actually present exceeds the amount required, then B is in excess and A is the limiting reagent. If the amount of B present is less than required, then B is the limiting reagent.
Excess is Coma's first English-language album, which was released in Europe on 11 October 2010. The album consists of nine tracks from Hipertrofia (2008), which were re-recorded in English, and three new songs: "F.T.P." and "F.T.M.O." from the movie Skrzydlate Świnie (where Rogucki played one of the main roles), and "Turn Back The River". On 1 September 2010, the album was made available to buy in Poland, but only via Mystic Production website.
