Vâlâyeš, verbal noun from vâlâ "sublime, majestic," may be a variant of bâlâ "up, above, high, elevated, height," variants boland "high," borz "height, magnitude" (it occurs also in the name of the mountain chain Alborz), Lori dialect berg "hill, mountain;" Mid.Pers. buland "high;" O.Pers. baršan- "height;" Av. barəz- "high, mount," barezan- "height;" cf. Skt. bhrant- "high;" L. fortis "strong" (Fr. & E. force); O.E. burg, burh "castle, fortified place," from P.Gmc. *burgs "fortress;" Ger. Burg "castle," Goth. baurgs "city," E. burg, borough, Fr. bourgeois, bourgeoisie, faubourg); PIE base *bhergh- "high."

subluminous star

A star that is less luminous than a main-sequence star of the same spectral type.

sub-; → luminous; → star.

Fr.: sous-marin   

(Adj.) Located, occurring, operating, or living beneath the surface of the → sea.

sub- + → marine.

submarine ridge
  روک ِ زیر-دریایی   
ruk-e zir-daryâ-yi


Geology: A long, steep elevation of the deep sea floor.

submarine; → ridge.

submarine spring
  چشمه‌ی ِ زیر-دریایی

  ۱) مرچیدن؛ ۲) مرچاندن   
1) marcidan; 2) marcândan

Fr.: submerger   

1) To sink or plunge under water or beneath the surface of any enveloping medium.
2) To cover or overflow with water; immerse (

From L. submergere, from → sub- + mergere "to dip, immerse;" probably by rhotacism from PIE *mezg- "to dip, plunge;" cf. Skt. majj- "to sink in water;" Lith. mazgoju "to wash."

Marcidan, from Av. mraoc- "to float, submerge;" cf. Skt. mroc/mloc "to go down, set (of the Sun), to disappear, to hide;" Kurd., Laki, Nahâvandi, Bovir-Ahmadi mala- "swim," Kurd. melâna "ship, boat," melaq "wave" may be related to this Av. form.


Fr.: sub-millimétrique   

Of or pertaining to scales smaller than millimeter.

sub-; → millimeter.

submillimeter astronomy
  اخترشناسی ِ زیر-میلیمتری   
axtaršenâsi-ye zir-milimetri

Fr.: astronomie sub-millimétrique   

The study of astronomical objects with → submillimeter waves. As with millimeter-wave astronomy, this part of the spectrum is rich in lines emitted by interstellar molecules and dust.

submillimeter; → astronomy.

submillimeter galaxy (SMG)
  کهکشان ِ زیر-میلیمتری   
kahkešân-e zir-milimetri

Fr.: galaxie sub-millimétrique   

A member of an extremely luminous population of → high-redshift galaxies which are detected in → submillimeter waves (→ flux density at 850 μm ≥ 3 - 5 mJy). SMGs are powered primarily by star formation rather than an → active galactic nucleus (AGN). Because of their high → dust content, these galaxies emit almost all of their luminosity in the infrared, with a → bolometric luminosity ranging from 1012-1013 → solar luminosities. As such, SMGs resemble → ultraluminous infrared galaxies (ULIRGs), which are almost exclusively → merging galaxies. Indeed, many observations support a → merger origin for SMGs (see, e.g. C.C. Hayward et al. 2011 and references therein, astro-ph/1101.0002).

submillimeter; → galaxy.

submillimeter radiation
  تابش ِ زیر-میلیمتری

submillimeter; → radiation.

submillimeter wave
  موج ِ زیر-میلیمتری   
mowj-e zir-milimetri

Fr.: onde sub-millimétrique   

An electromagnetic wave having wavelengths less than one millimeter (frequencies greater than 300 gigahertz).

millimeter; → wave.


Fr.: soumission   

An act or instance of submitting. The condition of having submitted. → submit

Verbal noun of → submit.


Fr.: soumettre   

To present for the approval, consideration, or decision of another or others. For example, to submit a research paper for publication, to submit an observing proposal.

From L. submittere "to yield, lower, let down, put under, reduce," from → sub- "under" + mittere "to let go, send."

Dar sepordan, dar sepârdan "to yield, surrender, give in," from dar "in, into" (→ in-) + sepordan/sepârdan "to give in charge, entrust to, deposit with;" ultimately Proto-Iranian *spar- "to hand over, entrust."


Fr.: sous preuve   

A proof that occurs within the context of a larger proof

sub-; → proof.


Fr.: subrelativiste   

Describing a system or situation for which the → Lorentz factor, γ, is much smaller than 1. See also → ultrarelativistic.
