|---|---|
| transport number | The fraction of the total current carried through a solution by a particular type of ion present in that solution. (05 Mar 2000) |
| turnover number | <biochemistry, pharmacology> Equivalent to Vmax, being the number of substrate molecules converted to product by one molecule of enzyme in unit time, when the substrate is saturating. (18 Nov 1997) |
| Kestenbaum's number | The difference between the two pupil diameters when each eye is measured in bright light with the other eye tightly covered; an indicator of the relative afferent pupillary defect in patients with two normally innervated irises. (05 Mar 2000) |
| Knoop hardness number | A number obtained by dividing the load in kg applied to a pyramid-shaped diamond of specific size divided by the projected area of the impression: KHN = L/A, where A= the projected area of the impression in mm2 and L= the load in kg; used for measurements of hardness of any materials, especially very hard and brittle substances such as tooth dentin and enamel. (05 Mar 2000) |
| Koettstorfer number | The number of milligrams of KOH required to saponify 1 g of fat; an approximate measure of the average molecular weight of a fat, with which it varies inversely. Synonym: Koettstorfer number. (05 Mar 2000) |
| fluoride number | The percent inhibition of pseudocholinesterase produced by fluorides; used to differentiate normal from atypical pseudocholinesterases. See: dibucaine number. (05 Mar 2000) |
| f-number | <radiobiology> In optics, denotes the ratio of the equivalent focal length of an objective lens to the diameter of its entrance pupil. (09 Oct 1997) |
| linking number | A property of a long biopolymer (such as duplex DNA) equal to the number of twists (related to the frequency of turns around the central axis of the helix) plus the writhing number. (05 Mar 2000) |
| Loschmidt's number | The number of molecules in 1 cm3 of ideal gas at 0캜 and 1 atmosphere of pressure; Avogadro's number divided by 22,414 (i.e., 2.6868 × 1019 cm-3). (05 Mar 2000) |
| acid wave | A temporary increase in the acidity of the urine occurring during fasting. Synonym: acid wave. (05 Mar 2000) |
| alkaline wave | A period of urinary neutrality or even alkalinity after meals due to withdrawal of hydrogen ion for the purpose of secretion of the highly acid gastric juice. Synonym: alkaline wave. (05 Mar 2000) |
| alpha wave | Brain waves in the encephalogram which have a frequency of 8 to 13 per second. They are typical of the normal person awake and in a quiet resting state, and occur principally in the occipital region. (12 Dec 1998) |
| arterial wave | A wave in the jugular phlebogram due to transmission of carotid artery pulsation. B wave, the initial positive deflection in the electroretinogram, possibly arising from the inner nuclear layer of the retina. (05 Mar 2000) |
| A wave | The initial negative deflection in the electroretinogram, presumably reflecting retinal photoreceptor activity, an atrial deflection in an electrocardiogram recorded from within the atrium of the heart, the first positive deflection of the atrial and venous pulses due to atrial systole.
