| occupational exposure | The exposure to potentially harmful chemical, physical, or biological agents that occurs as a result of one's occupation. (12 Dec 1998) |
|---|---|
| environmental exposure | The exposure to potentially harmful chemical, physical, or biological agents in the environment or to environmental factors that may include ionizing radiation, pathogenic organisms, or toxic chemicals. (12 Dec 1998) |
| exposure | <radiobiology> A quantitative measure of x or gamma radiation at a certain place, based on its ability to produce ionisation in air. The former special unit of exposure was the roentgen (R). 1R = 2.58 x 10-4 C/kg. In the international system (SI unit), the special unit is coulomb per kilogram. (Exposure also is frequently used as a synonym for irradiation). (16 Dec 1997) |
| exposure dose | The radiation dose, expressed in roentgens, delivered at a point in free air. Synonym: air dose. (05 Mar 2000) |
| exposure keratitis | Inflammation of the cornea resulting from irritation caused by inability to close the eyelids. Synonym: lagophthalmic keratitis. (05 Mar 2000) |
| exposure odds ratio | <epidemiology> See Odds ratio. (05 Dec 1998) |
| assisted mechanical ventilation | <anaesthetics> The use of a mechanical device to fill the lungs with oxygenated air then allow time for passive exhalation. (27 Sep 1997) |
| ventilators, mechanical | Mechanical devices used to produce or assist pulmonary ventilation. (12 Dec 1998) |
| mechanical | 1. Pertaining to, governed by, or in accordance with, mechanics, or the laws of motion; pertaining to the quantitative relations of force and matter, as distinguished from mental, vital, chemical, etc.; as, mechanical principles; a mechanical theory; mechanical deposits. 2. Of or pertaining to a machine or to machinery or tools; made or formed by a machine or with tools; as, mechanical precision; mechanical products. "We have also divers mechanical arts." (Bacon) 3. Done as if by a machine; uninfluenced by will or emotion; proceeding automatically, or by habit, without special intention or reflection; as, mechanical singing; mechanical verses; mechanical service. 4. Made and operated by interaction of forces without a directing intelligence; as, a mechanical universe. 5. Obtained by trial, by measurements, etc.; approximate; empirical. See the 2d Note under Geometric. Mechanical effect, effective power; useful work exerted, as by a machine, in a definite time. Mechanical engineering. See the Note under Engineering. Mechanical manoeuvres, the application of mechanical appliances to the mounting, dismounting, and moving of artillery. Mechanical philosophy, the principles of mechanics applied to the inverstigation of physical phenomena. Mechanical powers, certain simple instruments, such as the lever and its modifications (the wheel and axle and the pulley), the inclined plane with its modifications (the screw and the wedge), which convert a small force acting throught a great space into a great force acting through a small space, or vice versa, and are used separately or in combination. <mathematics> Mechanical solution, a solution of a problem by any art or contrivance not strictly geometrical, as by means of the ruler and compasses, or other instruments. Origin: From Mechanic. Source: Websters Dictionary (01 Mar 1998) |
