| scheme | 1. A combination of things connected and adjusted by design; a system. "The appearance and outward scheme of things." (Locke) "Such a scheme of things as shall at once take in time and eternity." (Atterbury) "Arguments . . . Sufficient to support and demonstrate a whole scheme of moral philosophy." (J. Edwards) "The Revolution came and changed his whole scheme of life." (Macaulay) 2. A plan or theory something to be done; a design; a project; as, to form a scheme. "The stoical scheme of supplying our wants by lopping off our desires, is like cuttig off our feet when we want shoes." (Swift) 3. Any lineal or mathematical diagram; an outline. "To draw an exact scheme of Constantinople, or a map of France." (South) 4. <astronomy> A representation of the aspects of the celestial bodies for any moment o at a given event. "A blue case, from which was drawn a scheme of nativity." (Sir W. Scott) Synonym: Plan, project, contrivance, purpose, device, plot. Scheme, Plan. Scheme and plan are subordinate to design; they propose modes of carrying our designs into effect. Scheme is the least definite of the two, and lies more in speculation. A plan is drawn out into details with a view to being carried into effect. As schemes are speculative, they often prove visionary; hence the opprobrious use of the words schemer and scheming. Plans, being more practical, are more frequently carried into effect. "He forms the well-concerted scheme of mischief; 'T is fixed, 't is done, and both are doomed to death." (Rowe) "Artists and plans relieved my solemn hours; I founded palaces, and planted bowers." (prior) Origin: L. Schema a rhetorical figure, a shape, figure, manner, Gr, form, shape, outline, plan, fr, to have or hold, to hold out, sustain, check, stop; cf. Skr. Sah to be victorious, to endure, to hold out, AS. Sige victory, G. Sieg. Cf. Epoch, Hectic, School. Source: Websters Dictionary (01 Mar 1998) |

| occlusal scheme | The form or design and arrangement of the occlusal and incisal units of a dentition or the teeth on a denture. Synonym: occlusal scheme. (05 Mar 2000) |
| Z scheme of photosynthesis | <biochemistry, biology> A schematic representation of the light reactions of photosynthesis, in which the photosynthetic reaction centres and electron carriers are arranged according to their electrode potential (free energy) in one dimension and their reaction sequence in the second dimension. This gives a Z shape, the two reaction centres (of photosystems I and II) being linked by the photosynthetic electron transport chain. (18 Nov 1997) |
| radioactive decay | <physics> The process by which a spontaneous change in nuclear state takes place. This process is accompanied by the emission of energy in various specific combinations of electromagnetic and corpuscular radiation and neutrinos. (16 Dec 1997) |
| decay | To pass gradually from a sound, prosperous, or perfect state, to one of imperfection, adversity, or dissolution; to waste away; to decline; to fail; to become weak, corrupt, or disintegrated; to rot; to perish; as, a tree decays; fortunes decay; hopes decay. "Ill fares the land, to hastening ills a prey, Where wealth accumulates and men decay." (Goldsmith) Origin: OF. Decaeir, dechaer, decheoir, F. Dechoir, to decline, fall, become less; L. De- + cadere to fall. See Chance. 1. Gradual failure of health, strength, soundness, prosperity, or of any species of excellence or perfection; tendency toward dissolution or extinction; corruption; rottenness; decline; deterioration; as, the decay of the body; the decay of virtue; the decay of the Roman empire; a castle in decay. "Perhaps my God, though he be far before, May turn, and take me by the hand, and more - May strengthen my decays." (Herbert) "His [Johnson's] failure was not to be ascribed to intellectual decay." (Macaulay) "Which has caused the decay of the consonants to follow somewhat different laws." (James Byrne) 2. Destruction; death. 3. Cause of decay. "He that plots to be the only figure among ciphers, is the decay of the whole age." (Bacon) Synonym: Decline, consumption. See Decline. Source: Websters Dictionary (01 Mar 1998) |
| decay accelerating factor | <biochemistry, protein> Plasma protein that regulates complement cascade by blocking the formation of the C3bBb complex (the C3 convertase of the alternate pathway). Widely distributed in tissues but deficient in paroxysmal nocturnal haemoglobinuria. (18 Nov 1997) |
| decay constant | <physics, radiobiology> The fraction of the amount of a radionuclide that undergoes transition per unit time. Formally: Lamda=dP/dt Where dP is the probability of a given nucleus undergoing spontaneous nuclear transition in the time interval dt. (16 Dec 1997) |
| decay modes | <radiobiology> Different pathways for decay of radioactive nuclei. The decay modes for a given unstable state can include beta emission (negative = electron, positive = positron), electron capture, alpha emission, fission, and gamma emission. (13 Nov 1997) |
| decay theory | A theory of forgetting based on the premise that an engram or memory trace dissipates progressively with time during the interval when it is not activated. (05 Mar 2000) |
| tone decay test | The sounding of a continuous tone at threshold for 1 min; if the intensity must be increased by more than 5 dB for continued perception, it may be a sign of retrocochlear damage. (05 Mar 2000) |
| exponential decay | <epidemiology> A decline in which the rate of decay is always proportional to the amount of material remaining; the constant of proportionality is the rate constant. (05 Dec 1998) |
| free induction decay | In magnetic resonance imaging, the decay curve that is detected by the radiofrequency coil after the application of an excitation pulse, without additional pulses (free). (05 Mar 2000) |
