| fast neutrons | Neutrons, the energy of which exceeds some arbitrary level, usually around one million electron volts. (12 Dec 1998) |
|---|---|
| fast pyrolysis | Thermal conversion of biomass by rapid heating to between 450> To 600>C in the absence of oxygen. (05 Dec 1998) |
| fast ray | <microscopy> The fast ray or fast component for a crystal or fibre corresponds to the lower refractive index. (05 Aug 1998) |
| fast smear | A cytologic smear containing material from the vaginal pool and pancervical scrapings, mixed and prepared on one microscopic slide, smeared, and fixed immediately; used principally for routine screening of ovaries, endometrium, cervix, vagina, and hormonal states. (05 Mar 2000) |
| Kluver-Barrera Luxol fast blue stain | <technique> In combination with cresyl violet, a stain useful for demonstrating myelin and Nissl substance. (05 Mar 2000) |
| liquid-metal fast-breeder reactor | <physics> Fission breeder reactor concept using liquid-metal coolant and breeding additional fuel off fast neutrons. See: breeder reactor. (09 Oct 1997) |
| Luxol fast blue | Name for a group of closely related copper phthalocyanin dyes used as stains (with PAS, PTAH, haematoxylin, silver nitrate, etc.) for myelin in nerve fibres. (05 Mar 2000) |
| anamnestic response | <immunology> Archaic term now replaced by such terms as secondary immune response, immune memory. (18 Nov 1997) |
| audiometry, evoked response | A form of electrophysiologic audiometry in which an analog computer is included in the circuit to average out ongoing or spontaneous brain wave activity. A characteristic pattern of response to a sound stimulus may then become evident. Evoked response audiometry is known also as electric response audiometry. (12 Dec 1998) |
| auditory brainstem response audiometry | An electrophysiologic measure of auditory function utilizing responses produced by the auditory nerve and the brainstem to repetitive acoustic stimuli. (05 Mar 2000) |
| biological response modifier | <pharmacology, oncology> A substance used in adjuvant therapy that takes advantage of the bodys own natural defense mechanisms to inhibit the growth of a tumour. (16 Dec 1997) |
| biological response modifiers | Substances that stimulate the body's response to infection and disease. The body naturally produces small amounts of these substances. Scientists can produce some of them in the laboratory in large amounts and use them in cancer treatment. Also called BRMs. (12 Dec 1998) |
| biphasic response | Two separate and distinct responses that are separated in time, immediate reaction to an antigenic challenge followed by a recurrence of symptoms after an interval of quiescence. (05 Mar 2000) |
| booster response | The response of the immune system to the second or subsequent occasion on which it encounters a specific antigen. (18 Nov 1997) |
| brainstem evoked response audiometry | An electrophysiologic measure of auditory function utilizing responses produced by the auditory nerve and the brainstem to repetitive acoustic stimuli. (05 Mar 2000) |
