1) tarâjâyidan; 2) tarâzabânidan
Fr.: 1) translater; 2) traduire
1a) Mechanics: To subject a body to → translation.
M.E. translaten, from L. translatus, from → trans- "across" + latus suppletive p.p. of ferre "to carry;" cognate with Pers. bordan "to carry, transport;" Mid.Pers. burdan; O.Pers./Av. bar- "to bear, carry," barəθre "to bear (infinitive);" Skt. bharati "he carries;" Gk. pherein "to carry;" PIE base *bher- "to carry."
1) Tarâjâyidan, from tarâ-, → trans- "across" +
jâ "place" (from Mid.Pers. giyag "place;" O.Pers. ā-vahana-
"place, village;" Av. vah- "to dwell, stay," vanhaiti "he dwells, stays;"
Skt. vásati "he dwells;" Gk. aesa (nukta) "to pass (the night);"
Ossetic wat "room; bed; place;" Tokharian B wäs- "to stay, wait;"
PIE base *ues- "to stay, live, spend the night")
+ -idan infinitive suffix.
A geometrical method in land surveying for the determination of the relative position of points. In contrast to → triangulation, trilateration involves measuring the lengths of the three sides of touching or overlapping triangles and not their angles.
very late thermal pulse (VLTP)
tape-ye garmâyi-ye besyâr dir
Fr.: flash de l'hélium très tardif
In evolutionary models of → post-asymptotic giant branch stars, the occurrence of the helium shell burning when the star has reached the → white dwarf cooling track. This leads to the possibility of a violent → helium shell flash and expansion on a time-scale of ≤ 10 years. The rapid expansion and prompt change in surface composition observed in → Sakurai's Object are thought to be due to such a very late thermal pulse.
To break, infringe, or transgress (a law, rule, agreement, promise, instructions, etc.). → parity violation.
M.E., from L. violatus p.p. of violare "to treat with violence, violate," from violentus "violent, " from vis "force, violence."
Enâhidan infinitive from enâh, from Av. aēnah- "violence, mischief, crime, outrage," from aēn- "to do violence to, to violate, to injure, to offend;" cf. Skt. énas- "offence, mischief, crime, sin;" Gk. ainos "terrible."
tiqe-ye mowj (#)
Fr.: lame à retard
An optical element that retards the phase of one plane of vibration of light relative to the plane at right angles. The two beams then recombine to form a single beam with new polarization characteristics. A typical wave plate is a birefringent crystal with a carefully chosen orientation and thickness. Also known as → retardation plate. A → half-wave plate creates a half-wave retardation. See also → quarter-wave plate.
X-ray Dim Isolated Neutron Star (XDINS)
setâre-ye notroni bâ partowhâ-ye X-e nazâr
Fr.: étoile à neutron de faibles rayons X
A member of a class of isolated, radio-silent → pulsars with peculiar properties. They show a purely thermal spectrum at X-ray energies with no evidence for a high-energy, power-law component often detected in other → isolated neutron star classes. The X-ray luminosity is 1031 - 1032 erg s-1, fully consistent with surface blackbody emission with temperatures ~ 40-100 eV and (radiation) radii of a few kilometers, as derived from X-ray spectral fits. With the only exception of RX J1856.5-3754, broad absorption features have been found in all XDINSs. These features have energies ~ 300 - 700 eV, equivalent widths of ~ 50 - 150 eV and, as in the case of RX J0720.4-3125, may be variable.
