| activated partial thromboplastin time | The time needed for plasma to form a fibrin clot following the addition of calcium and a phospholipid reagent; used to evaluate the intrinsic clotting system. (05 Mar 2000) |
| activated resin | Autopolymerizing resin, any resin that can be polymerised by chemical catalysis rather than by the application of heat; used in dentistry for dental restoration, denture repair, and impression trays. Synonym: activated resin, cold cure resin, cold-curing resin, quick cure resin, self-curing resin. (05 Mar 2000) |
| activated sludge | See: activated sludge method. (05 Mar 2000) |
| activated sludge method | A method of sewage disposal in which the sewage is treated with 15% bacterially active, liquid sludge, which is produced by repeated vigorous aeration of fresh sewage to form floccules or sediment; when this flocculation process is complete, the resulting activated sludge contains large numbers of bacteria, together with yeasts, molds, and protozoa, which actively effect the oxidation of organic compounds; this mixture is piped to a sedimentation tank, the effluent from which is completely treated sewage. (05 Mar 2000) |
| activated sludge process | <procedure> A method of treating sewage and wastewater through microbial oxidation. Sewage previously treated in settling tanks is aerated to encourage the growth of nonpathogenic aerobic microorganisms (bacteria, yeasts, moulds and protozoans) which break the organic matter down into carbon dioxide, water and simple salts. After this activated sludge is produced, the wastewater undergoes further processing through anaerobic digestion, filtering and chlorination. (29 Dec 1997) |
| activated state | <chemistry, radiobiology> An atom or nucleus which possesses more energy than its ground state energy. (16 Dec 1997) |

| basic polypeptide-activated protein kinase | <enzyme> Requires mn2+ for its activity; from bombyx mori; does not require cyclicamp, cyclicgmp or ca Registry number: EC 2.7.1.- Synonym: ba kinase (26 Jun 1999) |
| calcium-calmodulin-activated histone 3 arginine kinase | <enzyme> From nuclear extracts of dividing and quiescent rat heart endothelial cells; represents a new class of ca-cam-dependent kinases which phosphorylate arg Registry number: EC 2.7.10.- Synonym: ca(2+)-calmodulin-activated histone 3 arg kinase, ca-cam h3 kinase (26 Jun 1999) |
| Receptors for activated C Kinase | Synonym for endosome. (18 Nov 1997) |
