(0) (biology) The regulation of some aspect of a biological organism in a changing environment. The American Heritage® Student Science Dictionary, Second Edition. Currently unavailable. An adjustable resistance; an apparatus for changing the resistance without opening the circuit. The rheostat is a device that varies the resistance in a circuit without interrupting the flow of the current in the circuit. Rheotaxis definition, oriented movement of an organism in response to a current of fluid, especially water. To examine the rheostat-like functions of kinases, Kawashima et al. The English scientist Sir Charles Wheatstone coined the word rheostat, it is derived from the Greek word “rheos” and “-statis” which means a stream controlling device or a current controlling device. Conductor The movement of electron gives rise to the flow of current through metals an apparatus for regulating resistance in an electric circuit. A contrivance for adjusting or regulating the strength of electrical currents, operating usually by the intercalation of resistance which can be varied at will. A potentiometer is a three-terminal resistor with a sliding or rotating contact that forms an adjustable voltage divider. All other applications are mostly derived from this very current controlling property of the rheostat. The construction of rheostat is extremely related to potentiometer construction.

How to pronounce rheostat. The education of developing natural killer (NK) cells for optimal functional responsiveness at maturity — specialized to kill certain types of injurious target cells — appears to operate rheostatically, individual NK cells quantitatively tuned by graded inhibitory inputs during development. The measuring instrument called a potentiometer is essentially a voltage divider used for measuring electric potential; the component is an implementation of the same principle, hence its … We found that naive human T cells after mitogenic activation, apart from expected protective Bcl-2 members, also rapidly upregulate the BH3-only protein Noxa in a p53-independent fashion. Heterogeneity in the natural killer (NK) cell population is determined by variegated expression of polygenic and polymorphic receptors and distinct phenotypes and functions of NK cell subsets.
