| 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 health planning and development agencies | Agencies established under pl93-641 to coordinate, conduct, and implement state health planning activities. Two primary responsibilities are the preparation of an annual state health plan and giving assistance to the statewide health coordinating council. (12 Dec 1998) |
| state health plans | State plans prepared by the state health planning and development agencies which are made up from plans submitted by the health systems agencies and subject to review and revision by the statewide health coordinating council. (12 Dec 1998) |
