| steam conversion factors | (approximations) 1 pound of steam = 1,000 Btu = .3 kW. 10,000 lbs/hr steam = 300 boiler horsepower. (05 Dec 1998) |
|---|---|
| internal conversion electron | An electron, similar to an Auger electron, released from one of the electron orbits of the atom upon activation by a gamma-ray from that atom's nucleus; the electron has kinetic energy equal to the net energy transition of the disintegration. (05 Mar 2000) |
| thermal conversion cycle | <radiobiology> Process of generating electrical power with a fusion reactor by means of a steam / other gas turbine. This is distinct from direct conversion cycles. (09 Oct 1997) |
| thermochemical conversion process | Chemical reactions employing heat to produce fuels. (05 Dec 1998) |
| fibrinogen-fibrin conversion syndrome | <syndrome> A syndrome characterised by hypofibrinogenaemia with incoagulable blood; it may be seen in abruptio placentae, prolonged retention of a dead foetus in an Rh-isosensitised mother, haemolytic blood reactions, bilateral renal cortical necrosis, and cases of trauma. (05 Mar 2000) |
| lysogenic conversion | <virology> The ability of some phages to survive in a bacterium as a result of the integration of their DNA into the host chromosome. The integrated DNA is termed a prophage. A regulator gene produces a repressor protein that suppresses the lytic activity of the phage, but various environmental factors, such as ultraviolet irradiation may prevent synthesis of the repressor, leading to normal phage development and lysis of the bacterium. The best example of this is bacteriophage lambda. (18 Nov 1997) |
| atomic heat | The amount of heat required to raise an atom from 0 |
| radiant heat | Heat given off from any body in the form of waves, similar to light waves but of greater wavelength. (05 Mar 2000) |
| molar heat capacity | <chemistry> The amount of energy required to raise the temperature of one mole of a substance by one degree Celsius (or Kelvin). (09 Jan 1998) |
| molecular heat | The product of the specific heat of a body multiplied by its molecular weight. (05 Mar 2000) |
| combined heat and power | An older term for what is now generally called cogeneration. The term is currently used in Europe and other foreign countries. (05 Dec 1998) |
| conductive heat | Heat transmitted by direct contact, as by an electric pad or hot water bottle. (05 Mar 2000) |
| convective heat | Heat conveyed by a warm medium, such as air or water, in motion from its source. (05 Mar 2000) |
| conversive heat | Heat produced in a body by the absorption of waves that are not in themselves hot, such as the sun's rays or infrared radiation. (05 Mar 2000) |
| prickly heat | An eruption of papules and vesicles at the orifices of sweat glands, accompanied by redness and inflammatory reaction of the skin. Synonym: heat rash, lichen infantum, lichen strophulosus, prickly heat, strophulus, summer rash, tropical lichen, lichen tropicus, wildfire rash. (05 Mar 2000) |
