Foehn wind Labeling for preparations of aspirin combined with caffeine, codeine and the like will sometimes include "Föhnkrankheit" amongst the indications. Evidence for effects from Chinook winds remain anecdotal. The name "Foehn" (, ) arose in the Alpine region. Originating from Latin "(ventus) favonius", a mild west wind of which Favonius was the Roman personification and probably transmitted by or just "fuogn", the term was adopted as . In the Southern Alps, the phenomenon is known as föhn but also and fen in Croatian and Slovene. The German word "Fön" (without the "H", but pronounced the same way), a genericized trademark, also
Dirichlet boundary condition Dirichlet boundary condition In mathematics, the Dirichlet (or first-type) boundary condition is a type of boundary condition, named after Peter Gustav Lejeune Dirichlet (1805–1859). When imposed on an ordinary or a partial differential equation, it specifies the values that a solution needs to take on along the boundary of the domain. The question of finding solutions to such equations is known as the Dirichlet problem. In applied sciences, a Dirichlet boundary condition may also be referred to as a fixed boundary condition. For an ordinary differential equation, for instance, the Dirichlet boundary conditions on the interval take the form where
