| anaesthesia recovery period | The period of emergence from general anaesthesia, where different elements of consciousness return at different rates. (12 Dec 1998) |
|---|---|
| recovery | 1. A getting back or regaining; recuperation. 2. Emergence from general anaesthesia. 3. In nuclear magnetic resonance, refers to relaxation. Origin: M.E., fr. O.Fr. Recoverer, fr. L. Recupero, to recover, get back, fr. Re-, again, + capio, to take (05 Mar 2000) |
| recovery boiler | A pulp mill boiler in which lignin and spent cooking liquor (black liquor) is burned to generate steam. (05 Dec 1998) |
| recovery room | Hospital unit providing continuous monitoring of the patient following anaesthesia. (12 Dec 1998) |
| recovery score | A number expressing the condition of an infant at various stipulated intervals greater than 1 minute after birth and based on the same features assessed by the Apgar score at 60 seconds after birth. (05 Mar 2000) |
| materials recovery facility | A recycling facility for municipal solid waste. (05 Dec 1998) |
| resource conservation and recovery act | (RCRA) A federal law regulating solid and hazardous waste. RCRA governs the generation, storage, treatment, transport, and disposal of hazardous waste. (05 Dec 1998) |
| creep recovery | The time-dependent portion of the decrease in strain in a material or object following removal of the stress that has deformed it. (05 Mar 2000) |
| product recovery | The process of separating a desired recombinant protein from the growth medium and the other elements in the host cells in which it was grown. (14 Nov 1997) |
| sinoatrial recovery time | <cardiology, physiology> Interval from the last paced P wave to the first succeeding spontaneous P wave (after 2 to 5 minutes of right atrial pacing at 120 to 140 beats per minute, and when expressed as percentage of control cycle length, it normally ranges from 115 to 159%). (05 Mar 2000) |
| spontaneous recovery | The return of the conditioned response, after apparent extinction, in the presence of the conditioned stimulus without the unconditioned stimulus also being present. See: classical conditioning. (05 Mar 2000) |
| supernormal recovery phase | A brief period during the recovery of cardiac muscle following excitation when diseased muscle is more (i.e., less abnormally) excitable; corresponds to the end of the T wave in the ECG. (05 Mar 2000) |
| ultrasonic egg recovery | Obtaining an egg for in vitro fertilization by means of an ultrasonically guided needle aspiration of ovarian follicles; may be performed transvesically or via the cul-de-sac. (05 Mar 2000) |
| fluorescence recovery after photobleaching | Many fluorochromes are bleached by exposure to exciting light. If, for example: the cell surface is labelled with a fluorescent probe and an area bleached by laser illumination, then the bleached patch that starts off as a dark area will gradually recover fluorescence. The recovery is due to the re population of the area by unbleached molecules and diffusion of bleached molecules to other areas. The rate and extent of recovery are a measure of the fluidity of the membrane and the proportion of labelled molecules that are free to exchange with adjacent areas. The technique is usually applied to cell surface fluidity or viscosity measurements, but is also applicable to other structures. (18 Nov 1997) |
| allantoic fluid | The fluid within the allantoic cavity. (05 Mar 2000) |
