| flowers of benzoin | C6H5COOH;occurs naturally in gum benzoin; it is used as a food preservative, locally as a fungistatic, and orally as an antiseptic, diuretic, and expectorant. It is excreted rapidly as hippuric acid. Synonym: benzoyl hydrate, flowers of benzoin. (05 Mar 2000) |
| flowers of sulfur | Used in preparing sulfur ointment and in the treatment of various skin disorders. Synonym: flowers of sulfur. (05 Mar 2000) |
| flowers of zinc | <chemical> A mild astringent and topical protectant with some antiseptic action. It is also used in bandages, pastes, ointments, dental cements, and as a sunblock. Pharmacological action: dermatologic agents, sunscreening agents. Chemical name: Zinc oxide (ZnO) (12 Dec 1998) |
| flowing | That flows or for flowing (in various sense of the verb); gliding along smoothly; copious. <physics> Flowing battery, a sheet when eased off, or loosened to the wind, as when the wind is abaft the beam. Source: Websters Dictionary (01 Mar 1998) |
| flowing hyperostosis | A hypertrophying and condensing osteitis which tends to run in longitudinal streaks or columns, like wax drippings on a candle, and which involves a number of the long bones. Synonym: flowing hyperostosis, streak hyperostosis. Origin: rheo-+ G. Osteon, bone, + -osis, condition (05 Mar 2000) |
| pulsatile flow | Rhythmic, intermittent propagation of a fluid through a vessel or piping system, in contrast to constant, smooth propagation, which produces laminar flow. The quality of blood flow, whether smooth (laminar) or pulsatile, is important to the integrity of the tissues being artificially perfused by various heart assist devices or in regional perfusion. (12 Dec 1998) |
|---|---|
| sheared flow | <radiobiology> Fluid flow where the magnitude of the fluid velocity changes along a direction perpedicular to the direction of the fluid flow. (Freeway traffic often exhibits sheared flow in that traffic in the fast lane moves more rapidly than traffic in the slow lane with the exits.) Sheared flow typically correlates with reduced transport and enhanced confinement. (This definition is rather informal and may not be fully technically correct - R.F. Heeter) (09 Oct 1997) |
| shear flow | A flow of a material in which parallel planes in the material are displaced in a direction parallel to each other. (05 Mar 2000) |
| shuttle flow | <cell biology> Bulk flow of the cytoplasm of cells. most conspicuous in large cells such as amoebae and the internodal cells of Chara where the rate of movement may be as high as 100 m/sec. See: cyclosis. (18 Nov 1997) |
| newtonian flow | The type of flow characteristic of a newtonian fluid. (05 Mar 2000) |
| Doppler colour flow | A computer-generated colour image produced by Doppler ultrasonography in which different directions of flow are represented by different hues. This technique is typically used to examine blood flow when evaluating heart disease. Where obstructions (for instance, arterial plaques) exist, blood flow will alter according to the principles of fluid mechanics. Eddies and reversals are readily apparent on the colour image. See: Doppler ultrasonography. (05 Mar 2000) |
| instream flow incremental methodology | Technique to predict the biomass of a fish species or life stage that a stream reach can support at a given flow, given knowledge of the fishes' physical habitat preferences. (09 Oct 1997) |
| isovolume pressure-flow curve | The relationship between transpulmonary pressure and respiratory air flow, expressed as a function of lung volume. (05 Mar 2000) |
| effective renal blood flow | The amount of blood flowing to the parts of the kidney that are involved with production of constituents of urine. (05 Mar 2000) |
| effective renal plasma flow | <physiology> The amount of plasma flowing to the parts of the kidney that have a function in the production of constituents of urine; the clearance of substances such as iodopyracet and p-aminohippuric acid, assuming that the extraction ratio in the peritubular capillaries is 100%. It is the amount of plasma perfusing the kidney tubules per unit time, generally measured by p-aminohippurate clearance. It should be differentiated from renal plasma flow which is approximately 10% greater than the effective renal plasma flow. (07 Mar 2000) |
| karyotyping, flow | Use of flow cytometry to analyze and/or separate chromosomes on the basis of their DNA content. Flow cytometry detects the light- absorbing or fluorescing properties of chromosomes passing in a narrow stream through a laser beam and with automated sorting devices can sort successive droplets of the stream into different fractions depending on the fluorescence emitted by each droplet. (12 Dec 1998) |
| laminar air flow unit | An air-filtering system used at some transplant facilities to remove particulate matter and fungi from the air. (16 Dec 1997) |
| laminar flow | The relative motion of elements of a fluid along smooth parallel paths, which occurs at lower values of Reynolds number. (05 Mar 2000) |
| forced expiratory flow | Expiratory flow during measurement of forced vital capacity; subscripts specify the exact parameter measured, e.g., peak instantaneous flow, the instantaneous flow at some specified point on the curve of volume expired versus time, or on the flow-volume curve, the mean flow between two expired volumes. (05 Mar 2000) |
| forced expiratory flow rates | Measurements of rates of airflow during a forced vital capacity determination. (12 Dec 1998) |
