âtanu, from â- affirmative prefix + tanu "stretched, strained," from tan + -u suffix of excess. The middle element tan, from tanidan "to spin, twist, weave" (Mid.Pers. tanitan; Av. tan- to stretch, extend;" cf. Skt. tan- to spin, stretch;" tanoti "stretches," tantram "loom;" Gk. teinein "to stretch, pull tight;" L. tendere "to stretch;" PIE base *ten- "to stretch"), Pers. târ "string," tân "thread," tur "fishing net, net, snare," and tâl "thread" (Borujerdi dialect) belong to this family; variants tanta "cobweb," tanadu, tafen, kartané, kârtané, kâtené, Pashtu tanistah "cobweb;" cf. Skt. tantu- "cobweb, thread, string").

Agent noun of → intensify.

intensive; → prefix.

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").

  توند ِ جنبشیک   
tavand-e jonbešik

Fr.: potentiel cinétique
