| plasma wave | <physics> A disturbance of a plasma away from equilibrium, involving oscillations of the plasma's constituent particles and of an electromagnetic field. Plasma waves can propagate from one point in the plasma to another without net motion of the plasma. (09 Oct 1997) |
|---|---|
| muscle plasma | An alkaline fluid in muscle that is spontaneously coagulable, separating into myosin and muscle serum. (05 Mar 2000) |
| core plasma | <radiobiology> Hot plasma at the centre of a fusion reactor, distinguished from edge plasma and scrape-off layer (SOL). The core plasma does not directly feel the effects of the divertor or limiter in the way the edge plasma does. (09 Oct 1997) |
| pregnancy-associated alpha-plasma protein | An alpha 2-macroglobulin, molecular weight approximately 750,000 now believed to be a pregnancy-specific protein. Its plasma levels increase steadily during the second trimester and continue to rise until the end of gestation. (12 Dec 1998) |
| pregnancy-associated beta-plasma protein | A beta-globulin now believed to be a pregnancy-specific protein. Its plasma levels increase steadily during pregnancy until the end of gestation. (12 Dec 1998) |
| salted plasma | The fluid portion of blood drawn from the vessels, which is prevented from coagulating by being drawn into a solution of sodium or magnesium sulfate. Synonym: salted serum. (05 Mar 2000) |
| human plasma protein fraction | A sterile solution of selected proteins derived from the blood plasma of adult human donors, containing 4.5 to 5.5 g of protein per 100 ml, of which 83 to 90% is albumin and the remainder is alpha-and beta-globulins; used as a blood volume supporter. (05 Mar 2000) |
| standing plasma test | If plasma is stored at 4캜 upright in a test tube, chylomicrons will float to the top and form a creamy layer. (05 Mar 2000) |
| normal human plasma | Sterile plasma obtained by pooling approximately equal amounts of the liquid portion of citrated whole blood from eight or more adult humans who have been certified as free from any disease which is tranmissible by transfusion, and treating it with ultraviolet irradiation to destroy possible bacterial and viral contaminants. (05 Mar 2000) |
| dried human plasma protein fraction | Freeze-dried human plasma protein fraction. (05 Mar 2000) |
| d-shaped plasma | <radiobiology> A toroidal plasma whose cross-section (poloidal plane) is a D (instead of a circle). A D-shape has a higher beta limit than a circular shape. (09 Oct 1997) |
| quasineutral plasma | <physics> An ionised gas in which positive and negative charges are present in approximately equal numbers. (09 Oct 1997) |
| interstitial plasma cell pneumonia | <chest medicine> A pneumonia caused by an infection with Pneumocystis carinii. Pneumocystis carinii grows rapidly in the lungs of patients with immunosuppression, particularly due to AIDS and is the leading AIDS-related cause of death. Pneumocystis carinii infection sometimes may occur elsewhere in the body (skin, eye, spleen, liver or heart). It is considered one of the diagnostic criteria for AIDS in an HIV positive individual. (10 Jan 1998) |
| target plasma | <radiobiology> Plasma used to trap a neutral atom beam. A background plasma of sufficiently high density and temperature can ionize neutral atoms more effectively than the Lorentz process (where v cross B creates effective electric field). (09 Oct 1997) |
| temperature, plasma | <radiobiology> A measure of the random (thermal) kinetic energy of the ions or electrons in the plasma. The temperature of each component of a plasma depends on the mean kinetic energy of that component. An example of this is the fluorescent light bulb, which is an example of a weakly-ionised plasma where the electrons are at temperatures of tens of thousands of degrees, whereas the ions and neutrals are much cooler (so that you can touch the bulb without being burned). See: atomic temperature, electron temperature, ion temperature. (09 Oct 1997) |
