| international normalised ratio | System established by the world health organization and the international committee on thrombosis and haemostasis for monitoring and reporting blood coagulation tests. Under this system, results are standardised using the international sensitivity index for the particular test reagent/instrument combination used. (12 Dec 1998) |
|---|---|
| international system of units | A system of physical units in which the fundamental quantities are length, time, mass, electric current, temperature, luminous intensity, and amount of substance, and the corresponding units are the meter, second, kilogram, ampere, kelvin, candela, and mole. The system has been given official status and recommended for universal use by the general conference on weights and measures. (12 Dec 1998) |
| international unit | The amount of a substance, such as a drug, hormone, vitamin, enzyme, etc., that produces a specific effect as defined by an international body and accepted internationally; e.g., for an enzyme it is umole of product formed (or substrate consumed) per minute. Synonym: unit. (05 Mar 2000) |
| Leiter International Performance Scale | A nonverbal (performance) test for measuring intelligence which contains norms for each age between 2 and 18; originally developed as a method of assessing the comparative intellectual abilities of Caucasian, Chinese, and Japanese children, but now occasionally used for assessing slow learners and those who are blind, deaf, or verbally handicapped. (05 Mar 2000) |
| 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. (05 Aug 1998) |
| 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.
