| volume loading rate | The rate of raw materials put into a fermenter or aerobic digester, expressed in terms of material weight per unit volume per unit time. (09 Oct 1997) |
|---|
| acid loading test | <nephrology> This is a test used in the diagnosis of renal tubular acidosis. The patient takes ammonium chloride capsules for 3 days to acidify the blood (lower blood pH). A sample of the urine and the blood is then collected and the results are interpreted. (27 Sep 1997) |
|---|---|
| carbohydrate loading | A procedure popular with long-distance runners and other athletes of filling muscles with a large glycogen pool prior to an athletic event; often, the athlete consumes very few carbohydrates for three days followed by a largely carbohydrate diet for the last three days before the event. (05 Mar 2000) |
| wall loading | <radiobiology> Fusion reactor thermal output power divided by the area of the wall facing the plasma. (Neutron wall loading is 4/5 of the total for D-T fusion.) (09 Oct 1997) |
| salt loading | The administration of 2 g of sodium chloride (with a regular diet) 3 times a day for 4 days; a diagnostic test in primary aldosteronism, in which the salt loading produces the typical plasma electrolyte pattern. (05 Mar 2000) |
| soda loading | A procedure adopted by a number of athletes of ingesting sodium bicarbonate in an attempt to buffer the production of protons during exercise. (05 Mar 2000) |
| loading | Administration of a substance for the purpose of testing metabolic function. (05 Mar 2000) |
| loading dose | <pharmacology> A quantity higher than the average or maintenance dose, used at the initiation of therapy to rapidly establish a desired level of the drug (18 Nov 1997) |
| atomic volume | The atomic weight of an element divided by its density in the solid state; the volume of the gram-atomic weight of a solid element. (05 Mar 2000) |
| blood volume | Volume of circulating blood. It is the sum of the plasma volume and erythrocyte volume. (12 Dec 1998) |
| blood volume determination | Method for determining the circulating blood volume by introducing a known quantity of foreign substance into the blood and determining its concentration some minutes later when thorough mixing has occurred. From these two values the blood volume can be calculated by dividing the quantity of injected material by its concentration in the blood at the time of uniform mixing. Generally expressed as cubic centimeters or liters per kilogram of body weight. (12 Dec 1998) |
| blood volume nomogram | A nomogram used to predict blood volume on the basis of the individual's weight and height. (05 Mar 2000) |
| cardiac volume | The volume of the heart, usually relating to the volume of blood contained within it at various periods of the cardiac cycle. The amount of blood ejected from a ventricle at each beat is stroke volume. (12 Dec 1998) |
| packed cell volume | <haematology> Measurement of the proportion of the blood occupied by the red blood cells. Normal values are 40-54% in males, 35-47% in females. (13 Nov 1997) |
| maximal expiratory flow-volume curve | <chest medicine> Curves depicting maximal expiratory flow in liters/second at each point of lung inflation (expressed in liters or percentage of forced vital capacity) during a forced vital capacity determination. Common abbreviation is mefv. (12 Dec 1998) |
| partial volume | The actual volume occupied by one species of molecule or particle in a solution; the reciprocal of the density of the molecule. (05 Mar 2000) |
