| pair production | <physics> The simultaneous production of an electron and a positron by an interaction of a photon or a fast charged particle with the electronic field of a nucleus or other particle. (16 Dec 1997) |
|---|---|
| primary production | Production of organic substances by photosynthesis, the quantity of material so produced per unit time. (09 Oct 1997) |
| production | The act or process of producing, bringing forth or making. (18 Nov 1997) |
| speech production measurement | Measurement of parameters of the speech product such as vocal tone, loudness, pitch, voice quality, articulation, resonance, phonation, phonetic structure and prosody. (12 Dec 1998) |
| steroid production rate | The total quantity of a given steroid formed in the body, usually expressed as milligrams per day; represents the sum of the glandular secretion of the steroid and extraglandular formation of it from various steroid precursors. (05 Mar 2000) |
| implantation theory of the production of endometriosis | That, at the time of menstruation, cells of the uterine mucosa pass through the fallopian tubes and escape into the pelvic cavity where they implant themselves on the peritoneum. (05 Mar 2000) |
| orphan drug production | Production of drugs or biologicals which are unlikely to be manufactured by private industry unless special incentives are provided by others. (12 Dec 1998) |
| Abegg's rule | The tendency of the sum of the maximum positive and maximum negative valence of a particular element to equal 8; e.g., C may have a valence of +4 and -4, O of +6 and -2. Sometimes loosely stated as all atoms have the same number of valences, a consequence of the tendency of valence electron shells to be filled to 8. (05 Mar 2000) |
| American Law Institute rule | A test of criminal responsibility (1962): "a person is not responsible for criminal conduct if at the time of such conduct as a result of mental disease or defect he lacks substantial capacity either to appreciate the wrongfulness of his conduct or to conform his conduct to the requirements of law." (05 Mar 2000) |
| astigmatism against the rule | Astigmatism when the greater curvature or refractive power is in the horizontal meridian. (05 Mar 2000) |
| astigmatism with the rule | Astigmatism when the greater curvature or refractive power is in the vertical meridian. (05 Mar 2000) |
| pair rule gene | <molecular biology> A segmentation gene, expressed sequentially between gap genes and segment polarity genes. In development of Drosophila, a set of about 8 genes that are expressed only in alternate segments (odd or even) of the developing embryo. Loss of function mutants thus lack alternate segments. Examples: even skipped (eve), fushi tarazu (ftz), hairy. (18 Nov 1997) |
| Gibb's phase rule | An expression of the relationships existing between systems in equilibrium: P + V = C + 2, where P is the number of phases, V the variance or degrees of freedom, and C the number of components; it also follows that the variance is, V = C + 2 -P. For H2O at its triple point, V = 1 + 2 -3 = 0, i.e., both temperature and pressure are fixed. Synonym: Gibb's phase rule. (05 Mar 2000) |
| Gloger's rule | The rule or observation that the skin of a warm-blooded animal species tends to become darker in colour towards warmer climates at lower altitudes or lower latitudes, and to become lighter in colour towards colder climates at higher altitudes or higher latitudes. (09 Oct 1997) |
| Goriaew's rule | Rarely used term for a rule of a blood counting field by which it is marked off in a series of squares, some of which are again subdivided into sixteen smaller ones. (05 Mar 2000) |
