| magnetic viscosity | <physics> A magnetic field in a conducting fluid will damp fluid motions perpendicular to the field lines, similar to ordinary viscosity, even in the absence of sizeable mechanical forces or electric fields. (09 Oct 1997) |
|---|---|
| relative viscosity | The ratio of the viscosity of a solution or dispersion to the viscosity of the solvent or continuous phase. (05 Mar 2000) |
| viscosity | <chemistry> A physical property of fluids that determines the internal resistance to shear forces. (18 Nov 1997) |
| coefficient of viscosity | The value of the force per unit area required to maintain a unit relative velocity between two parallel planes a unit distance apart. (05 Mar 2000) |
| Poiseuille's viscosity coefficient | An expression of the viscosity as determined by the capillary tube method; the coefficient η = (πPr4t/8vl), where P is the pressure difference between the inlet and outlet of the tube, r the radius of the tube, l its length, and v the volume of liquid delivered in the time t. If volume is in cm3, time is in seconds, and l and r are in cm, then n will be in poise. (05 Mar 2000) |
| newtonian viscosity | The viscosity characteristics of a newtonian fluid. (05 Mar 2000) |
| dynamic viscosity | The internal or molecular frictional resistance of a fluid by Newton's law of viscosity as the ratio of the applied force per unit area to the relative velocity of adjacent fluid layers (produced by the force). (05 Mar 2000) |
| kinematic viscosity | A measure used in studies of fluid flow; the dynamic viscosity, u, in poises divided by the density of the material; units: stokes. (05 Mar 2000) |
| antihemophilic plasma | Human plasma in which the labile antihemophilic globulin component, present in fresh plasma, has been preserved; it is used to temporarily relieve dysfunction of the haemostatic mechanism in haemophilia. (05 Mar 2000) |
| apical plasma membrane | <cell biology> The term used for the cell membrane on the apical (inner or upper) surface of transporting epithelial cells. This region of the cell membrane is separated, in vertebrates, from the baso lateral membrane by a ring of tight junctions that prevents free mixing of membrane proteins from these two domains. (18 Nov 1997) |
| basolateral plasma membrane | <cell biology> The plasma membrane of epithelial cells that is adjacent to the basal lamina or the adjoining cells of the sheet. Differs both in protein and phospholipid composition from the apical plasma membrane from which it is isolated by tight junctions (zonula occludentes). (18 Nov 1997) |
| beam-plasma reaction | <radiobiology> Fusion reaction which occurs from the collision of a fast beam ion with a thermal plasma ion. (09 Oct 1997) |
| bean-shaped plasma | <radiobiology> A toroidal plasma indented on the inboard side (the side with the donut hole), that results in additional stability to ballooning modes. Moderate indentation may provide access to the second-stability region (high beta). (13 Nov 1997) |
| blood plasma | <haematology> Acellular fluid in which blood cells are suspended. Serum obtained by defibrinating plasma (plasma derived serum) lacks platelet released factors and is less suitable to support the growth of cells in culture. (13 Oct 1997) |
| blood plasma fractions | Portions of the blood plasma as separated by electrophoresis or other technique. (05 Mar 2000) |
