| economy | 1. The management of domestic affairs; the regulation and government of household matters; especially as they concern expense or disbursement; as, a careful economy. "Himself busy in charge of the household economies." (Froude) 2. Orderly arrangement and management of the internal affairs of a state or of any establishment kept up by production and consumption; especially, such management as directly concerns wealth; as, political economy. 3. The system of rules and regulations by which anything is managed; orderly system of regulating the distribution and uses of parts, conceived as the result of wise and economical adaptation in the author, whether human or divine; as, the animal or vegetable economy; the economy of a poem; the Jewish economy. "The position which they [the verb and adjective] hold in the general economy of language." (Earle) "In the Greek poets, as also in Plautus, we shall see the economy . . . Of poems better observed than in Terence." (B. Jonson) "The Jews already had a Sabbath, which, as citizens and subjects of that economy, they were obliged to keep." (Paley) 4. Thrifty and frugal housekeeping; management without loss or waste; frugality in expenditure; prudence and disposition to save; as, a housekeeper accustomed to economy but not to parsimony. Political economy. See Political. Synonym: Economy, Frugality, Parsimony. Economy avoids all waste and extravagance, and applies money to the best advantage, frugality cuts off indulgences, and proceeds on a system of saving. The latter conveys the idea of not using or spending superfluously, and is opposed to lavishness or profusion. Frugality is usually applied to matters of consumption, and commonly points to simplicity of manners, parsimony is frugality carried to an extreme, involving meanness of spirit, and a sordid mode of living. Economy is a virtue, and parsimony a vice. "I have no other notion of economy than that it is the parent to liberty and ease." (Swift) "The father was more given to frugality, and the son to riotousness [luxuriousness]" (Golding) Origin: F. Economie, L. Oeconomia household management, fr. Gr, fr. One managing a household; house (akin to L. Vicus village, E. Vicinity) + usage, law, rule, fr. To distribute, mange. See Vicinity, Nomad. Source: Websters Dictionary (01 Mar 1998) |

| token economy | A practice whereby tokens representing money, toys, candy, etc., are given as secondary reinforcers contingent upon certain desired behaviours or performances. (12 Dec 1998) |
| 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) |
| thermal expansion | <radiobiology> Characteristic property of most solids and liquids which causes their volume to increase when they are heated. Thermal expansion and contraction can cause structural problems in pulsed fusion devices. (09 Oct 1997) |
| 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) |
