biologist zistšenâs (#) Fr.: biologiste An expert or specialist in biology. |
biology zistženâsi (#) Fr.: biologie The study of living organisms and their interactions with the non living world. |
bioluminescence zist-foruzesti Fr.: bioluminescence The production and emission of light by a living organism as the result of a chemical reaction (→ chemiluminescence). In other words, bioluminescence is chemiluminescence from living organisms. It is widespread in the marine environment, but rare in terrestrial and especially freshwater environments. → chemi-; → luminescence. |
biomarker zist-dâjgar Fr.: biomarqueur A biologic feature that is measured and evaluated as an indicator of normal biological processes, pathogenic processes, or pharmacological responses to a therapeutic intervention. For example, prostate specific antigen (PSA) is a biomarker for cancer of the prostate. |
biophysicist zistfizikdân (#) Fr.: biophysicien A specialist in → biophysics. |
biophysics zistfizik (#) Fr.: biophysique The science that deals with biological structures and processes involving the application of physical principles and methods. |
biosignature zist-nešânzad Fr.: biosignature A substance or phenomenon whose presence in an object such as a → meteorite or an → exoplanet indicates the existence of life. |
biosphere zistsepehr (#) Fr.: biosphère The part of a planet or moon within which life can occur. It may include the crust, oceans, and atmosphere. |
Biot-Savart law qânun-e Biot-Savart (#) Fr.: loi de Biot-Savart The → magnetic field due to → electric current flowing in a long straight conductor is directly proportional to the current and inversely proportional to the distance of the point of observation from the conductor. The law is derivable from → Ampere's law, but was obtained experimentally by the authors. Named after the French physicists Jean-Baptiste Biot (1774-1862) and Félix Savart (1791-1841); → law. |
biotic environment pargir-e zistik Fr.: environnement biotique Ecology: The environment consisting of living organisms, which interact with each other and with their non-living surroundings. Biotic adj. of → biotics; of → environment. |
biotics zistik Fr.: biotique The science concerned with the functions of life, or vital activity and force. From biotic, from Gk. biotikos "of or pertaining to life," from → bio- + -tic a suffix equivalent in meaning to → -ic. |
bipolar doqotbi (#) Fr.: bipolaire Having two poles; having two opposite main structures or components. Bipolar, from → bi- + → polar, from → pole. Doqotbi, from do-, → bi-, + qotbi, → polar, from qotb, → pole. |
bipolar flow tacân-e doqotbi Fr.: flot bipolaire Same as → bipolar outflow. |
bipolar jet šân-e doqotbi Fr.: jet bipolaire One of two beams of high-temperature, ionized gas ejected in two opposite directions associated with a → protostar. The collimated jets, a consequence of the → accretion process, can extend over distances of several → light-years. |
bipolar nebula miq-e doqotbi Fr.: nébuleuse bipolaire An interstellar cloud of ionized gas with two main lobes which lie symmetrically on either side of a central star. The bipolar shape is generally due to the ejection of material by the central star in opposing directions. |
bipolar outflow ostacân-e doqotbi Fr.: flot bipolaire A flow of gaseous material in two opposite directions emanating from protostellar regions or from → evolved stars during the early post-→ AGB evolution. In protostellar regions → molecular outflows are pushed by → bipolar jets. |
birefringence došekast (#) Fr.: biréfringence A property of some crystalline materials (e.g. calcite, quartz) which have different indices of refraction associated with different crystallographic directions. Therefore, the crystal splits incident transmitted light into two beams, each polarized perpendicularly to the other. Also called double refraction. Birefringence, from → bi- + refringence, from L. refringere "to break up," from → re- "back" + combination form of frangere "to break." Došekast, from do- "two," → bi- + šekast "breaking," from šekastan "to break up," Mid.Pers. škastan, Av. skand- "to break." |
birefringent došekastgar, došekasti (#) Fr.: biréfringent Of or relating to → birefringence. |
birefringent filter pâlâye-ye došekastgar, ~ došekasti Fr.: filtre biréfringent A type of narrow-band filter that uses the birefringence to produce selective absorption of polarized light. → birefringent; → filter. |
birefringent vacuum xala'-e došekastgar Fr.: vide biréfringent Empty space undergoing → vacuum birefringence. → birefringent; → vacuum. |
