M.Fr. absorber, from L. absorbere "to swallow up," from ab- "from" + sorbere "suck in;" PIE root *srebh- "to suck, absorb;" cf. Arm. arbi "I drank;" Gk. rhophein "to sup up, gulp down;" Lith. srebiu "to drink greedily;" Proto-Iranian *hrab- "to sip, suck (in)," cf. Pashto raw-, Shaghni râv-, Sariqoli rov-, Ishkashimi ruv- "to suck" (Cheung 2007), Pers. (prefixed) zâlu "leech."
Daršamidan, from daršam, from dar- "in, into" + šam, variant of šâm, as in âšâm, âšâmidan "to drink, to sip;" Av. šam- "to drink, sip, swallow;" Skt. cam, camati "to sip, drink, lick up, absorb."
Capable of being absorbed.
Daršamidani adj. from aršamidan "to absorb" + -i, → -able.
The ability of a solution or a layer of a substance to absorb → radiation, i.e. the ratio of the intensity of the light incident on the solution to the intensity transmitted by it, in logarithmic scale.
Absorbent, from → absorb + -ent.
Daršamandé from aršam present stem of daršamidan, → absorb, + -andé suffix forming adj. and/or agent name.
Any medium that absorbs something.
Fr.: coin absorbant
Optics: A strip or annulus of material, such as glass or film, whose density increases progressively from one end to the other. The function of the wedge is to weaken the light beam in an optical system.
To take up and hold another substance on the surface.
1) A material that can hold or condense molecules of another substance
on its surface by adsorption.
From → adsorb + →-ent.
Baršamandé, from baršamidan, → adsorb, + -andé.
Fr.: absorbeur froid
A broad → absorption feature observed in → X-ray spectra of → active galactic nuclei (AGN). It is caused by material associated with the → interstellar medium in our → Galaxy and/or the host galaxy of the AGN or cold material near the AGN. → Quasars commonly have their X-ray spectrum absorbed by cold gas between us and the quasar X-ray source (along our → line of sight). This is particularly common in less luminous quasars. See also → warm absorber.
Verbal form of → desorption.
To gather on a surface either by absorption, adsorption, or a combination of the two processes.
Verb, from sorption, extracted from → absorption→ adsorption, from L. sorbere "suck in," from PIE base *srebh- "to suck, absorb" (cf. Arm. arbi "I drank;" Gk. rhopheo "to gulp down;" Lith. srebiu "to drink greedily").
Šamidan, from šam, variant of šâm, as in âšâm, âšâmidan "to drink, to sip;" Av. šam- "to drink, sip, swallow;" Skt. cam, camati "to sip, dirink, lick up, absorb."
Fr.: absorbeur chaud
A cloud of ionized gas within → active galactic nuclei (AGN) that causes absorption at → soft X-ray wavelengths. Warm absorbers were first suggested by Halpern (1984) to explain Einstein data of the quasar MR 2251-178. They are dubbed "warm" absorbers as they imply gas at temperatures of 104-105 K; the gas is → photoionized, not collisionally ionized. High resolution observations of warm absorbers have shown that they are outfowing. See also → cold absorber (Ceri Ellen Ashton, 2005, A Study of Warm Absorbers in Active Galactic Nuclei, Thesis, Mullard Space Science Laboratory Department of Space and Climate Physics University College London ).
