Fr.: instrumentation   

1) The design and use of scientific instruments for detection, measurement, control, computation, and so on.
2) The ensemble of instruments contained in a given machine or system.

From → instrument + -ation a combination of -ate and -ion, used to form verbal nouns.

Sâzâlgari, noun from sâzâlgar, → instrumentalist. Sâzâlgân, with plurality suffix -gân.

  عایق کردن   
âyeq kardan (#)

Fr.: isoler   

To cover or to separate from conducting bodies by means of nonconductors so as to prevent or reduce the passage, transfer, or leakage of heat, electricity, or sound. → insulation, → insulator.

From L. insulatus "made into an island," from L. insula "island."

From âyeq, → insulator, + kardan "to do," → -or.

âyeqkâri (#)

Fr.: isolation   

1) The act or fact of insulating.
2) Any material used to reduce or prevent the transfer of electricity, heat, cold, or sound.

Verbal noun from → insulate.

âyeq (#)

Fr.: isolant   

1) A material or an object that does not easily allow heat, electricity, light, or sound to pass through it.
2) Electricity: A material, such as glass or porcelain, that opposes a very high resistance to the passage of an electric current so that the flow of current through it is negligible; a nonconductor.
3) One who, or that which, insulates.

Agent noun from → insulate + → -or.

Âyeq, loan from Ar.

bimé (#)

Fr.: assurance   

The act, system, or business of insuring property, life, one's person, etc., against loss or harm arising in specified contingencies, as fire, accident, death, disablement, or the like, in consideration of a payment proportionate to the risk involved (

insure; → -ance.

Bimé, from bim "fear, danger" (variant bâk "fear, hesitation"); Mid.Pers. bīm "fear, fright, dread;" Av. b(a)ii- "to fear;" cf. Skt. bhayi- "to fear," bhīmá- "terrible;" Lith. bijoti(s), Latv. bîtiês "to fear, be afraid;" O.H.G. biben "to shiver;" PIE *bheiH2- "to fear" (Cheung 2007).

Fr.: s'assurer   

1) To provide or obtain → insurance on or for.
2) Make certain that something is definitely so. Same as make sure and ensure.

Variant of → ensure.

1) Bimé kardan, from bimé, → insurance, + kardan "to do, make," → -ize.
2) Dartenzidan, from dar-, → in-, + tenz, → sure, + -idan infinitive suffix, → -ize.

dorost (#)

Fr.: entier   

Same as → integer number.

From L. integer "whole," literally "intact, untouched," from → in- "not" + root of tangere "to touch."

Dorost "whole, complete; healthy; right," → integral.
