| radio frequency current drive | <radiobiology> Plasma waves in the radio-frequency range can be used to push plasma particles in such a way that current forms in the plasma, this is a method of non-inductive current drive which would allow for steady-state fusion reactors to operate. (09 Oct 1997) |

| current drive | <radiobiology> Any of a variety of techniques used to cause current flow in a plasma. See inductive current drive, RF current drive, non-inductive current drive. Usually applied to schemes used to generate current in tokamaks and other toroidal devices which require internal plasma currents. See: bootstrap current. (09 Oct 1997) |
|---|---|
| inductive current drive | <physics> Method to drive current in a toroidal plasma by using the torus of conducting plasma as the second coil in a transformer. The primary coil usually runs down the centre of the torus, changes in the current driven through the primary coil create changing magnetic fields which drive current in the plasma. The current thus driven can be used to heat the plasma as well (see also ohmic heating, induction). (09 Oct 1997) |
| radio frequency heating | <radiobiology> Process for heating the plasma by transferring energy to ions or electrons using waves generated by an external oscillator at an appropriate frequency. (This is similar to how a microwave oven heats food.) There are various types: See: ECRH, ICRH, and Lower Hybrid. (09 Oct 1997) |
| radio frequency or radiofrequency | <physics> Term used to describe electromagnetic radiation with frequencies less than infrared, but greater than audio frequencies, i.e., greater than about 15,000 Hz. Wavelengths are therefore less than about 20,000 km and greater than about 0.01 mm. (These numbers are not precise.) (09 Oct 1997) |
| high frequency current | An alternating electric current having a frequency of 10,000 or more per second; it produces no muscular contractions and does not affect the sensory nerves. Synonym: d'Arsonval current, Tesla current. (05 Mar 2000) |
| meiotic drive | Differential fitness in males and females. (05 Mar 2000) |
| direct drive | <radiobiology> An approach to inertial-confinement fusion in which the energy of the driver (laser or particle beam) is directly incident on the (usually spherical) target, causing compression heating via ablation of the target surface. (09 Oct 1997) |
| drive | 1. To rush and press with violence; to move furiously. "Fierce Boreas drove against his flying sails." (Dryden) "Under cover of the night and a driving tempest." (Prescott) "Time driveth onward fast, And in a little while our lips are dumb." (Tennyson) 2. To be forced along; to be impelled; to be moved by any physical force or agent; to be driven. "The hull drives on, though mast and sail be torn." (Byron) "The chaise drives to Mr. Draper's chambers." (Thackeray) 3. To go by carriage; to pass in a carriage; to proceed by directing or urging on a vehicle or the animals that draw it; as, the coachman drove to my door. 4. To press forward; to aim, or tend, to a point; to make an effort; to strive; usually with at. "Let them therefore declare what carnal or secular interest he drove at." (South) 5. To distrain for rent. To let drive, to aim a blow; to strike with force; to attack. "Four rogues in buckram let drive at me." 1. To impel or urge onward by force in a direction away from one, or along before one; to push forward; to compel to move on; to communicate motion to; as, to drive cattle; to drive a nail; smoke drives persons from a room. "A storm came on and drove them into Pylos." (Jowett (Thucyd)) "Shield pressed on shield, and man drove man along." (Pope) "Go drive the deer and drag the finny prey." (Pope) 2. To urge on and direct the motions of, as the beasts which draw a vehicle, or the vehicle borne by them; hence, also, to take in a carriage; to convey in a vehicle drawn by beasts; as, to drive a pair of horses or a stage; to drive a person to his own door. "How . . . Proud he was to drive such a brother!" (Thackeray) 3. To urge, impel, or hurry forward; to force; to constrain; to urge, press, or bring to a point or state; as, to drive person by necessity, by persuasion, by force of circumstances, by argument, and the like. " Enough to drive one mad." "He, driven to dismount, threatened, if I did not do the like, to do as much for my horse as fortune had done for his." (Sir P. Sidney) 4. To carry or; to keep in motion; to conduct; to prosecute. [Now used only colloquially] "The trade of life can not be driven without partners." (Collier) 5. To clear, by forcing away what is contained. "To drive the country, force the swains away." (Dryden) 6. <chemical> To dig Horizontally; to cut a horizontal gallery or tunnel. 7. To pass away; said of time. Drive, in all its senses, implies forcible or violent action. It is the reverse of to lead. To drive a body is to move it by applying a force behind; to lead is to cause to move by applying the force before, or in front. It takes a variety of meanings, according to the objects by which it is followed; as, to drive an engine, to direct and regulate its motions; to drive logs, to keep them in the current of a river and direct them in their course; to drive feathers or down, to place them in a machine, which, by a current of air, drives off the lightest to one end, and collects them by themselves. "My thrice-driven bed of down." Origin: AS. Drifan; akin to OS. Driban, D. Drijven, OHG. Triban, G. Treiben, Icel. Drifa, Goth. Dreiban. Cf. Drift, Drove. Source: Websters Dictionary (01 Mar 1998) |
| exploratory drive | The drive typical of toddlers and some animals to investigate the unfamiliar or unknown. (05 Mar 2000) |
| learned drive | Causing motion; having power to move, or tending to move; as, a motive argument; motive power. "Motive faculty. <machinery> " Motive power, a natural agent, as water, steam, wind, electricity, etc, used to impart motion to machinery; a motor; a mover. Source: Websters Dictionary (01 Mar 1998) |
| radio | 1. <physics> The transmission and reception of electric impulses or signals by means of electric waves without a connecting wire, or the use of these waves for the wireless transmission of electric impulses into which sound is converted. 2. <anatomy, prefix> A combining form indicating connection with, or relation to, a radius or ray; specifically, with the radius of the forearm; as, radio-ulnar, radiomuscular, radiocarpal. Origin: L. Radius, ray (21 Jun 2000) |
| radio-flagellata | <zoology> A group of Protozoa having both flagella and pseudopodia. Origin: NL. See Radiate, and Flagellata. Source: Websters Dictionary (01 Mar 1998) |
| radio label | A mildly radioactive molecule that is used to tag another molecule (such as a protein) so that it can be identified as it goes through some kind of biochemical process. (09 Oct 1997) |
| radio wave | <physics> Electromagnetic radiation with wavelengths of 300 millimetres or longer (even up to several kilometres). Radiation of this type is used to broadcast radio and television signals, and has frequencies up to thousands of megahertz (or one gigahertz). (09 Oct 1997) |
| radio waves | That portion of the electromagnetic spectrum beyond the microwaves, with wavelengths as high as 30 km. They are used in communications, including television. Short wave or hf (high frequency), uhf (ultrahigh frequency) and vhf (very high frequency) waves are used in citisen's band communication. (12 Dec 1998) |
