Fr.: boson intermédiaire   

A hypothetical → elementary particle that mediates the → weak interaction, carrying its effect from one particle to another as the photon does for electromagnetic interactions. First introduced in 1961 by Sheldon Glashow.

intermediate; → boson.

Fr.: infrarouge moyen   

The infrared radiation with wavelengths between about 1.5 and 20 microns. → near infrared; → far infrared.

intermediate; → infrared.

intermediate-mass black hole (IMBH)
  سیه‌چال ِ میان‌جرم   
siyah câl-e miyân jerm

Fr.: trou noir de masse intermédiaire   

A → black hole with a mass in the range 102-104 solar masses. IMBHs may form as the result of multiple → mergers of smaller objects in the centers of dense stellar clusters in the present universe, assuming → mass loss from → stellar winds is not significant. They may also arise from the evolution of → very massive stars early in the history of the Universe, forming black hole "seeds" in the centers of massive halos (the precursors of the galaxies we see today) early in the history of the Universe, to redshifts z > 10. Currently the best observational evidence for IMBHs comes from models of ultraluminous X-ray sources (See, e.g., J. M. Centrella et al. 2010, astro-ph/1010.5260).

intermediate; → mass; → black; → hole.

intermediate-mass protostar

intermittency
  رفت-و-ماند   
raftomând (#)

Fr.: intermittence   

A property of a turbulent dynamical system which is characterized by chaotic, irregular behavior occurring between quiet (or less irregular) periods. In other words, a → turbulent flow having a large → Reynolds number undergoes a phenomenon in which its turbulent activity at a fixed location stops from time to time and starts again. In fact → turbulence never completely disappears, but it can become extremely weak interrupted irregularly by bursts of strong turbulence (see also → developed turbulence). For intermittent flows → probability density functions are not → Gaussian. Turbulent intermittency plays a fundamental role in fields ranging from combustion physics, chemical engineering, meteorology, to astrophysical systems, more specifically the → interstellar medium.

From L. intermittent, pr.p. of intermittere "to leave a space between, drop (for a while), leave off," from → inter- + mittere "to send, let go."

Raftomând, literally "to go and to stop," from raft past stem of raftan "to go, walk, proceed" (present stem row-); Mid.Pers. raftan, raw-, Proto-Iranian *rab/f- "to go; to attack") + -o- euphonic infix + mând past stem of mândan "to remain, stay, relinquish, leave" (Mid.Pers. mândan "to remain, stay," mân "house, home;" O.Pers. mān- "to remain, dwell;" Av. man- "to remain, dwell; to wait;" cf. Gk. menein "to remain;" L. manere "to stay, remain, abide," mansio "a staying, a remaining, night quarters, station" (Fr. maison, ménage; E. manor, mansion, permanent; PIE *men- "to remain, wait for").

  درونی   
daruni (#)

Fr.: interne   

Situated or occurring in the interior of something; interior.

From M.L. internalis, from L. internus "within," from inter "between," → inter-.

Daruni, adj. of darun " in, into; within" (Mid.Pers. andarôn "inside," from andar, → inter-, + rôn "side, direction;" Av. ravan- "(course of a) river").

internal absorption
  درشم ِ درونی
