thermal

1. of, relating to, caused by, or generating heat or increased temperature
2. (of garments or fabrics) specially designed so as to have exceptional heat-retaining properties
3. Meteorol a column of rising air caused by local unequal heating of the land surface, and used by gliders and birds to gain height

thermal

[′thər·məl]
(meteorology)
A relatively small-scale, rising current of air produced when the atmosphere is heated enough locally by the earth's surface to produce absolute instability in its lower layers.
(thermodynamics)
Of or concerning heat.

thermal

A column of rising air heated by the sun or other phenomena. Sailplane and glider pilots use it for soaring. The pilots recognize the presence of a thermal with the help of a variometer—an instrument having two tubes with red and green indicators. A red means a downward air current, and a green means an upward air current, or a thermal. See variometer.

Variance analysis for the variable "bulk spikelet sterility" detected as significant the triple interaction among genotype x temperature x thermic stress/control, indicating that each genotype responded differently to the temperature variation and the imposition of the thermic stress (Table 1).

Binns said that previous studies involving high- and low-protein diets have typically examined the athletic populations and morbidly obese individuals, but she wanted to see what the thermic effect of food was like for a normal individual, who didn't have any metabolic disorders or medications that would affect their metabolism.
Part of the research was petrographic study of the rocks before and after the exposure to the high temperatures, observations of the thermic deepened openings, characteristics and analysis of the rock structure near the deepened openings, furthermore characteristics of the cracks and melt penetration into the cracks, characteristics of the melts.
Thermic has already partnered with companies like Sysco Corp (NYSE:SYY), Safeway Inc (NYSE:SWY), Trinity Industries Inc (NYSE:TRN) for pilot programmes.
NEAH Energy will form a special purpose acquisition vehicle for the transaction, which will involve the purchase of Thermics' intellectual property rights, applications, pending and already approved patents as well as its ultimate refrigerated transport vehicle (URTV) trucks, equipment and other miscellaneous assets, it noted.
* [lambda] = the mean thermic conductivity of the panel (3.36 W/m x K);
At the cooling of the exterior structure, by thermic transfer towards the interior one, this is contracted, causing pressure to the interior one.
The decoration was accomplished with UV-curing printing colors in offset and silk-screen, which are solvent-less compared to traditional thermic dyes and varnishes.
This is known as the 'thermic effect of food' (TEF) or 'specific dynamic action of food.' However, not all foods have the same 'thermic' effect.
A strict control of the electrical and thermic energy of each machine assures accurate cost control.
