| addition polymer | <chemistry> A polymer which is formed from the fusion of two monomers which join completely without losing any small molecules. (15 Jan 1998) |
|---|---|
| condensation polymer | <chemistry> The kind of polymer that is formed by the combination of monomers and the release of a small molecules at the point where monomers are joined. (05 Jan 1998) |
| polymer | <chemistry> A macromolecule made of repeating (monomer) units or protomers. (18 Nov 1997) |
| polymer fume fever | An occupational disease marked by fever, pain in the chest, and cough caused by the inhalation of fumes given off by a plastic, polytetrafluorethylene, when heated. (05 Mar 2000) |
| British Thermal Unit | <unit> Unit of energy needed to raise one pound of water by one degree fahrenheit. It is equal to 252 calories or 1055 Joules. Acronym: BTU (13 Nov 1997) |
| differential thermal analysis | Technique by which phase transitions of chemical reactions can be followed by observation of the heat absorbed or liberated. (12 Dec 1998) |
| thermal | Pertaining to or characterised by heat. (18 Nov 1997) |
| thermal anaesthesia | Loss of temperature appreciation. (05 Mar 2000) |
| thermal barrier | <radiobiology> In magnetic mirror devices, this is a depression of electrostatic potential formed by enhancing ion loss in the region between the central cell and the positive potential plug. The thermal barrier significantly reduces the density requirements in the plug and lowers the overall power required to sustain the solenoidal plugging by thermally decoupling central cell electrons from the end plugs. (09 Oct 1997) |
| thermal burn | A burn caused by heat. (05 Mar 2000) |
| thermal capacity | <chemistry> The amount of energy required to raise the temperature of an object by one degree Celsius (or Kelvin), it is represented by the symbol C and is given in units of J/K. (09 Jan 1998) |
| thermal conductivity | <radiobiology> Degree to which a substance transmits heat. (basic definition, I believe, is: (heat flow) = (thermal conductivity) (temperature gradient)) (09 Oct 1997) |
| 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) |
| thermal cover | Vegetative condition, generally with greater than 70% canopy closure and 40 feet in height, that can significantly ameliorate weather effects such as wind, heat, cold, and snow. Used by wildlife in winter. (05 Dec 1998) |
| thermal efficiency | <radiobiology> Ratio of the electric power produced by a power plant to the original amount of heat produced. This measures the efficiency with which the thermal energy is converted to electricity. (09 Oct 1997) |
