Blackout (drug-related amnesia)

A misfire or blackout (from English to black out, dim ') is the sudden complete failure of a state. The term is used in English only in certain contexts.

Meanings

  • Originally the term referred to the sudden blackout, complete extinction of the spotlight as the end of a scene in the cabaret, later also in the theater. This creates a very strong reduction of the contrast so that the audience can no longer see and recognize.
  • When blackout is defined as the sudden loss of power of large power grids. Particularly popular was the term with the major power outage in 2003 in the U.S. and the blackout in Europe in November 2006.
  • As a station blackout or black case is referred to in energy technology to a power failure in a power plant. Gas-fired power plants and oil-fired power plants can be approached without electricity; other Kaftwerkstypen need substantial amounts of electricity (or other energy) for the starting process (and some start-up time; see coal power plant start- # ).
  • Nuclear power plants need after a shutdown (eg scram ) significant amounts of electricity to operate the pumps of the cooling system on. Each nuclear reactor produces decay heat after shutdown; if this is not removed, the fuel rods melt ( meltdown ); there is also a risk of explosion (see Nuclear disaster of Fukushima, 2011). A station blackout is therefore to be avoided.
  • As a blackout (or blackout ) is the colloquial term for a temporary loss of memory; this may be associated with loss of consciousness. An example of this is the test anxiety that can culminate in that one actually does not remember in a test on what they have learned.
  • In addition, you can suffer a blackout in an alcohol - drunken stupor, which may manifest as loss of memory of up to several hours ( medically: amnesia or palimpsest ).
