| post-steady state | Any period of time, particularly in an enzyme-catalyzed reaction, after the steady-state interval; e.g., when the rate of product formation is declining in an enzyme-catalyzed reaction. (05 Mar 2000) |
|---|---|
| pre-steady state | Those conditions and the time interval prior to establishment of steady state. (05 Mar 2000) |
| hospitals, state | Hospitals controlled by agencies and departments of the state government. (12 Dec 1998) |
| singlet state | A transient, excited state of a molecule (e.g., of chlorophyll, upon absorbing light) that can release energy as heat or light (fluorescence) and thus return to the initial (ground) state; it may alternatively assume a slightly more stable, but still excited state (triplet state), with an electron still dislocated as before but with reversed spin. (05 Mar 2000) |
| hypnoid state | A drowsy or sleeplike state artificially induced by a hypnotist in individuals of higher than average levels of suggestibility. See: hypnosis. (05 Mar 2000) |
| hypnotic state | <procedure> A state of heightened awareness and focused concentration that can be used to manipulate the perception of pain. (16 Dec 1997) |
| hypometabolic state | A rare state of reduced metabolism with symptoms resembling hypothyroidism but with some tests for thyroid gland function normal; also used to describe the reduced metabolic activity seen in true hypothyroidism. (05 Mar 2000) |
| solid-state detector | A detector that uses a crystalline scintillating material rather than an ionization chamber to detect or measure radiation. (05 Mar 2000) |
| solid state laser | <radiobiology> A laser using a transparent substance (crystalline or glass) as the active medium, doped to provide the energy states necessary for lasing. The pumping mechanism is the radiation from a powerful light source, such as a flashlamp. The ruby, Nd-YAG, and Nd:glass lasers are solid-state lasers. (09 Oct 1997) |
| standard state | <chemistry> The most stable form of a substance at 298 K and 1 atmosphere of pressure. (09 Jan 1998) |
| state | <chemistry> The condition of the system at a given time, it is usually defined by an equation which is called an equation of state. (09 Jan 1998) |
| state dentistry | Control, direction and financing of the total dental care of the population by a national government. (12 Dec 1998) |
| state-dependent learning | Learning during a specific state of sleep or wakefulness, or during a chemically altered state, where retrieval of learned information (e.g., as measured by performance of a learned response) cannot be demonstrated unless the subject is restored to the state that originally existed during learning. (05 Mar 2000) |
| state function | <chemistry> A property that is independent of the pathway, this function can be used to define or specify the state of the system. (09 Jan 1998) |
| state government | The complex of political institutions, laws, and customs through which the function of governing the state is carried out (u.s. Only). (12 Dec 1998) |
