| conversion reaction | A conversion of emotional stress or mental disturbance into a physical symptom. Examples include paralysis, blindness, inability to speak or another sudden debilitating problem for no reason evident through testing. (27 Sep 1997) |
| stand conversion | The conversion of a noncommercial stand of timber to a commercial stand. (05 Dec 1998) |
| steam conversion factors | (approximations) 1 pound of steam = 1,000 Btu = .3 kW. 10,000 lbs/hr steam = 300 boiler horsepower. (05 Dec 1998) |
| internal conversion electron | An electron, similar to an Auger electron, released from one of the electron orbits of the atom upon activation by a gamma-ray from that atom's nucleus; the electron has kinetic energy equal to the net energy transition of the disintegration. (05 Mar 2000) |
| thermal conversion cycle | <radiobiology> Process of generating electrical power with a fusion reactor by means of a steam / other gas turbine. This is distinct from direct conversion cycles. (09 Oct 1997) |
| thermochemical conversion process | Chemical reactions employing heat to produce fuels. (05 Dec 1998) |
| fibrinogen-fibrin conversion syndrome | <syndrome> A syndrome characterised by hypofibrinogenaemia with incoagulable blood; it may be seen in abruptio placentae, prolonged retention of a dead foetus in an Rh-isosensitised mother, haemolytic blood reactions, bilateral renal cortical necrosis, and cases of trauma. (05 Mar 2000) |
| lysogenic conversion | <virology> The ability of some phages to survive in a bacterium as a result of the integration of their DNA into the host chromosome. The integrated DNA is termed a prophage. A regulator gene produces a repressor protein that suppresses the lytic activity of the phage, but various environmental factors, such as ultraviolet irradiation may prevent synthesis of the repressor, leading to normal phage development and lysis of the bacterium. The best example of this is bacteriophage lambda. (18 Nov 1997) |
| acidified serum test | Lysis of the patient's red cells in acidified fresh serum, specific for paroxysmal nocturnal haemoglobinuria. Synonym: Ham's test. (05 Mar 2000) |
| anticomplementary serum | Serum that destroys or inactivates complement. (05 Mar 2000) |
