| thermal melting profile | In general a record of the phase state of a system over a temperature range. Phase changes can be detected by exothermy or endothermy. Valuable in studying lipid and DNA structures. (18 Nov 1997) |
|---|---|
| thermal neutron | <radiobiology> A neutron in thermal equilibrium with its surrounding environment. Thermal neutrons are those that have been slowed down by a moderator to speeds characteristic of the local temperature. Compare: fast neutron. (09 Oct 1997) |
| thermal resource | A facility that produces electricity by using a heat engine to power an electric generator. The heat may be supplied by the combustion of coal, oil, natural gas, biomass, or other fuels, including nuclear fission, solar, or geothermal resources. (05 Dec 1998) |
| thermal sense | The ability to distinguish differences of temperature. Synonym: temperature sense, thermal sense, thermic sense, thermesthesia. Origin: thermo-+ G. Aisthesis, sensation (05 Mar 2000) |
| thermal sensors | Sensors that detect tiny changes in heat or temperature. (14 Nov 1997) |
| thermal spectrum | The part of the invisible spectrum of wave length just longer than that of visible red light. Synonym: thermal spectrum. (05 Mar 2000) |
| thermal velocity | <radiobiology> Average speed (magnitude of velocity) of a particle at a given temperature (in a Maxwellian velocity distribution). (09 Oct 1997) |
| absolute unit | A unit whose value is constant regardless of place or time and not derived from dependent on gravitation. (05 Mar 2000) |
| alexin unit | The smallest amount (highest dilution) of complement that will cause haemolysis of a unit of red blood cells in the presence of a haemolysin unit. Synonym: alexin unit. (05 Mar 2000) |
| Allen-Doisy unit | The quantity of oestrogen capable of producing in a spayed mouse a characteristic change in the vaginal epithelium, namely, disappearance of leukocytes and appearance of cornified cells, as determined by a vaginal smear; equal approximately to one-half of an estrone unit. Synonym: mouse unit. (05 Mar 2000) |
| amboceptor unit | haemolysin unit |
| androgen unit | The androgenic activity of 100 ug (0.1 mg) of crystalline androsterone as assayed by the comb growth response in capons. (05 Mar 2000) |
| antigen unit | The smallest amount of antigen that, in the presence of specific antiserum, will fix 1 complement unit. (05 Mar 2000) |
| antitoxin unit | A unit expressing the strength or activity of an antitoxin; in general, determined with reference to a preserved standard preparation of antitoxin. See: L doses. (05 Mar 2000) |
| antivenene unit | The amount of antivenum which, injected in the ear vein, will protect 1 g weight of rabbit against a fatal dose of snake venom. (05 Mar 2000) |
| British thermal unit |
A unit of measure for heat (equal to 1055 J).

| British thermal unit |
The amount of energy required to heat a pound of water 1 degree Fahrenheit. The Btu is the unit commonly used in calculating energy requirements. (It can apply to any energy use, not just heating water; for example, air conditioners are often rated by their Btu capacity.)

| British thermal unit |
The mean British Thermal Unit (BTU) is 1/180 of the heat required to raise the temperature of one-pound (1 lb.) of water from 32?F to 212?F at a constant atmospheric pressure. It is about equal to the quantity of heat required to raise one-pound (1 lb.) of water 1?F.
