| pace | 1. A single movement from one foot to the other in walking; a step. 2. The length of a step in walking or marching, reckoned from the heel of one foot to the heel of the other; used as a unit in measuring distances; as, he advanced fifty paces. Ordinarily the pace is estimated at two and one half linear feet; but in measuring distances be stepping, the pace is extended to three feet (one yard) or to three and three tenths feet (one fifth of a rod). The regulation marching pace in the English and United States armies is thirty inches for quick time, and thirty-six inches for double time. The Roman pace (passus) was from the heel of one foot to the heel of the same foot when it next touched the ground, five Roman feet. 3. Manner of stepping or moving; gait; walk; as, the walk, trot, canter, gallop, and amble are paces of the horse; a swaggering pace; a quick pace. "To-morrow, and to-morrow, and to-morrow, Creeps in this petty pace from day to day." (Shak) "In the military schools of riding a variety of paces are taught." (Walsh) 4. A slow gait; a footpace. 5. Specifically, a kind of fast amble; a rack. 6. Any single movement, step, or procedure. "The first pace necessary for his majesty to make is to fall into confidence with Spain." (Sir W. Temple) 7. A broad step or platform; any part of a floor slightly raised above the rest, as around an altar, or at the upper end of a hall. 8. A device in a loom, to maintain tension on the warp in pacing the web. Geometrical pace, the space from heel to heel between the spot where one foot is set down and that where the same foot is again set down, loosely estimated at five feet, or by some at four feet and two fifths. See Roman pace in the Note under def. 2. To keep, or hold, pace with, to keep up with; to go as fast as. "In intellect and attainments he kept pace with his age." Origin: OE. Pas, F. Pas, from L. Passus a step, pace, orig, a stretching out of the feet in walking; cf. Pandere, passum, to spread, stretch; perh. Akin to E. Patent. Cf. Pas, Pass. Source: Websters Dictionary (01 Mar 1998) |

| gene products, rev | Trans-acting nuclear proteins whose functional expression are required for HIV viral replication. Specifically, the rev gene products are required for processing and translation of the HIV gag and env mRNAs, and thus rev regulates the expression of the viral structural proteins. Rev can also regulate viral regulatory proteins. A cis-acting antirepression sequence (car) in env, also known as the rev-responsive element (rre), is responsive to the rev gene product. Rev is short for regulator of virion. (12 Dec 1998) |
| genes, rev | DNA sequences that form the coding region for a protein that regulates the expression of the viral structural and regulatory proteins in human immunodeficiency virus (HIV). Rev is short for regulator of virion. (12 Dec 1998) |
| rev | <molecular biology> A regulatory protein produced by HIV within infected cells. Rev helps transport HIV RNA sequences (messenger RNA) out from the nucleus into the cells cytoplasm, where it directs construction of proteins for new virus particles. (11 Jan 1998) |
| Abbe's law of limiting resolution | <physics> For a periodic structure of units separated by distance d and obliquely illuminated by the unrefracted ray and one of the two diffracted rays (extremely oblique illumination). Abbe applied the law of diffraction: d = 0.5 lambda /NA, where: lambda = wavelength of the monochromic light or shortest of mixed wavelengths NA = the limiting numerical aperture (NA) of objective or condenser.

| all or none law | Consistently total response to any effective stimulus. Synonym: all or none law. (05 Mar 2000) |
| American Law Institute formulation | Used in certain jurisdictions to determine criminal responsibility in legal proceedings. See: criminal insanity. (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) |
| Ampere's law | <physics> General equation in electromagnetism relating the magnetic field and the currents generating it. The various forms of the equation can be found in an introductory electromagnetism text. (09 Oct 1997) |
| Angstrom's law | A substance absorbs light of the same wavelength as it emits when luminous. (05 Mar 2000) |
| Arndt's law | An obsolete law stating that weak stimuli excite physiologic activity, moderately strong ones favour it, strong ones retard it, and very strong ones arrest it. (05 Mar 2000) |
| Arrhenius law | The theory of electrolytic dissociation (1887) that became the basis of our modern understanding of electrolytes: in an electrically conductive solution (e.g., acid, base, or salt), free ions are present before electrolysis, and the proportion of molecules dissociated into ions can be calculated from measurements of electrical conductivity as well as of osmotic pressure. Synonym: Arrhenius law. (05 Mar 2000) |
| Avogadro's law | Equal volumes of gases contain equal numbers of molecules, the conditions of pressure and temperature being the same. Synonym: Ampere's postulate, Avogadro's hypothesis, Avogadro's postulate. (05 Mar 2000) |
| Baer's law | The general organ characteristics found in all members of a group appear earlier in embryogenesis than the special organ characteristics that distinguish specific members of the group; this law is the predecessor of the recapitulation theory. (05 Mar 2000) |
| Baruch's law | The effect of any hydriatric procedure is in direct proportion to the difference between the temperature of the water and that of the skin; when the temperature of the water is above or below that of the skin the effect is stimulating; when the two temperatures are the same the effect is sedative.
