| systolic gradient | The difference in pressure during systole between two communicating cardiovascular chambers, e.g., between the left ventricle and aorta in aortic stenosis. (05 Mar 2000) |
| electrochemical gradient | A measure of the tendency of an ion to move passively from one point to another, taking into consideration the differences in its concentration and in the electrical potentials between the two points; commonly expressed as the additional voltage needed to achieve equilibrium. (05 Mar 2000) |
| ficoll gradient | A density gradient of ficoll (synthetic sucrose polymer) in solution, where concentration of the ficoll varies continuously through the solution. It is often used to separate different types of cells from each other during the process of sedimentation. (09 Oct 1997) |
| field gradient | In magnetic resonance imaging, a magnetic field that varies with location, superimposed on the uniform field of the magnet, to alter the resonant frequency of nuclei and allow recovery of their spatial position. Synonym: field gradient. (05 Mar 2000) |
| burns, electric | Burns produced by contact with electric current or from a sudden discharge of electricity. (12 Dec 1998) |
| magneto-electric | <physics> Pertaining to, or characterised by, electricity by the action of magnets; as, magneto-electric induction. Magneto-electric machine, a form of dynamo-electric machine in which the field is maintained by permanent steel magnets instead of electromagnets. Source: Websters Dictionary (01 Mar 1998) |
| resino-electric | <physics> Containing or exhibiting resinous electricity. Source: Websters Dictionary (01 Mar 1998) |
| volta-electric | Of or pertaining to voltaic electricity, or voltaism. Source: Websters Dictionary (01 Mar 1998) |
| hydro-electric | Pertaining to, employed in, or produced by, the evolution of electricity by means of a battery in which water or steam is used. <physics> Hydro-electric machine, an apparatus invented by Sir William Armstrong of England for generating electricity by the escape of high-pressure steam from a series of jets connected with a strong boiler, in which the steam is produced. Origin: Hydro-, 1 + electric. Source: Websters Dictionary (01 Mar 1998) |
| dynamo-electric | <physics> Pertaining to the development of electricity, especially electrical currents, by power; producing electricity or electrical currents by mechanical power. Origin: Gr. Power + E. Electric. See Dynamic. Source: Websters Dictionary (01 Mar 1998) |
| electric | <physics> A nonconductor of electricity, as amber, glass, resin, etc, employed to excite or accumulate electricity. Source: Websters Dictionary (01 Mar 1998) |
| electric anaesthesia | Anaesthesia, usually general anaesthesia, produced by application of an electrical current. (05 Mar 2000) |
| electric bath | A bath in which the medium is charged with electricity. Synonym: hydroelectric bath. Therapeutic application of static electricity, with the patient placed on an insulated platform. (05 Mar 2000) |
| electric cardiac pacemaker | An electric device that can substitute for the normal cardiac pacemaker, controlling the heart's rhythm by artificial electric discharges. Synonym: electronic pacemaker. (05 Mar 2000) |
