| direct current | (DC) Electric current which travels continuously in the same direction over a sustained period of time, contrast with AC (Alternating Current) which oscillates as a function of time. (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) |
| Tesla 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) |
| eddy current | <radiobiology> Electric current induced inside a conductor when the conductor (a) moves through a nonuniform magnetic field, or (b) experiences a change in the magnetic flux through its surface. (09 Oct 1997) |
| eddy-current loss | <radiobiology> Energy loss due to eddy currents circulating in a resistive material. (09 Oct 1997) |
| toroidal current | <radiobiology> Current flowing in the toroidal direction (the long way) around a torus. (As distinct from poloidal currents flowing through the centre of the torus and around to the outside, the short way.) (09 Oct 1997) |
| labile current | An electrical current applied to the body by means of electrodes that are constantly shifted about. (05 Mar 2000) |
| abortion, recurrent | See Abortion, habitual. (12 Dec 1998) |
| anterior tibial recurrent artery | <anatomy, artery> A branch of the anterior tibial artery which ascends to supply the front and sides of the knee joint, thus contributing to the articular network of the knee. Synonym: arteria recurrens tibialis anterior. (05 Mar 2000) |
| radial recurrent artery | <anatomy, artery> Origin, radial; distribution, ascends around lateral side of elbow joint; anastomoses, radial collateral, interosseous recurrent. Synonym: arteria recurrens radialis, recurrent radial artery. (05 Mar 2000) |
| recurrent | Returning after intermissions. Origin: L. Recurrens = returning (18 Nov 1997) |
| recurrent albuminuria | A functional albuminuria sometimes observed intermittently in cycles of 12 to 36 hours' duration, chiefly in younger persons; the degree of albuminuria is usually slight. Synonym: recurrent albuminuria. (05 Mar 2000) |
| recurrent aphthous stomatitis | <dermatology> Roundish pearl-coloured specks or flakes in the mouth, on the lips, etc, terminating in white sloughs, better known as thrush and the specks are called aphthae. Synonym: thrush, candidiasis. Origin: Sing. Of Aphthae. L, fr. Gr. (mostly in pl, Hipp) an eruption, thrush, fr. To set on fire, inflame. (25 Jun 1999) |
| recurrent aphthous ulcers | <dermatology> Roundish pearl-coloured specks or flakes in the mouth, on the lips, etc, terminating in white sloughs, better known as thrush and the specks are called aphthae. Synonym: thrush, candidiasis. Origin: Sing. Of Aphthae. L, fr. Gr. (mostly in pl, Hipp) an eruption, thrush, fr. To set on fire, inflame. (25 Jun 1999) |
| recurrent appendicitis | Repeated episodes of right lower quadrant abdominal pain attributed to recurrence of inflammation of the appendix in an individual who did not have an appendectomy for prior episodes. Synonym: relapsing appendicitis. (05 Mar 2000) |
