Flux is the net movement of particles across a specified area in a specified period of time. [1] The particles may be ions or molecules, or they may be larger, like insects, muskrats or cars. The units of time can be anything from milliseconds to millennia. Flux is not the same as velocity or speed nor is it the same as density or concentration.
Given a flux according to the electromagnetism definition, the corresponding flux density, if that term is used, refers to its derivative along the surface that was integrated. By the Fundamental theorem of calculus , the corresponding flux density is a flux according to the transport definition.
Since one of the assumptions of the GHK flux equation is that the ions move independently of each other, the total flow of ions across the membrane is simply equal to the sum of two oppositely directed fluxes. Each flux approaches an asymptotic value as the membrane potential diverges from zero. These asymptotes are
Flux (biology), movement of a substance between compartments; Flux (metabolism), the rate of turnover of molecules through a metabolic pathway; 4-Fluoroamphetamine (4-FA; PAL-303; "Flux"), a central nervous system stimulant with quasi-amphetamine effects; Dysentery, or other diseases called "flux", which cause the loss of fluid by diarrhea or ...
At the time when biologist Carl Linnaeus (1707–1778) published the books that are now accepted as the starting point of binomial nomenclature, Latin was used in Western Europe as the common language of science, and scientific names were in Latin or Greek: Linnaeus continued this practice.
Flux is therefore of great interest in metabolic network modelling, where it is analysed via flux balance analysis and metabolic control analysis. In this manner, flux is the movement of matter through metabolic networks that are connected by metabolites and cofactors , and is therefore a way of describing the activity of the metabolic network ...
Scientific terminology is the part of the language that is used by scientists in the context of their professional activities. While studying nature, scientists often encounter or create new material or immaterial objects and concepts and are compelled to name them.
Physics – negentropy, stochastic processes, and the development of new physical techniques and instrumentation as well as their application. Quantum biology – The field of quantum biology applies quantum mechanics to biological objects and problems. Decohered isomers to yield time-dependent base substitutions. These studies imply ...
