| dark current | <physiology> Current caused by constant influx of sodium ions into the rod outer segment of retinal photoreceptors and that is blocked by light (leading to hyperpolarization). The plasma membrane sodium channel is controlled through a cascade of amplification reactions initiated by photon capture by rhodopsin in the disc membrane. (18 Nov 1997) |

| d'Arsonval 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) |
| demarcation current | The current set up when an injured part of a nerve, muscle, or other excitable tissue is connected through a conductor with the uninjured region; the injured tissue is negative to the uninjured. Synonym: demarcation current. (05 Mar 2000) |
| descending current | The direction of current flow in a nerve when the cathode is placed peripheral to the anode, in contrast to ascending current. Synonym: centrifugal current. (05 Mar 2000) |
| 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) |
| red-short | <chemistry> Hot-short; brittle when red-hot; said of certain kinds of iron. Red"-shortness. Source: Websters Dictionary (01 Mar 1998) |
| congenitally short oesophagus | <radiology> Very rare findings: nonreducible intrathoracic gastric segment, short straight oesophagus, circular narrowing at GE junction frequently with ulcer, GE reflux see also: hiatal hernia (12 Dec 1998) |
| hot-short | <chemistry> More or less brittle when heated; as, hot-short iron. Source: Websters Dictionary (01 Mar 1998) |
| short | 1. Not long; having brief length or linear extension; as, a short distance; a short piece of timber; a short flight. "The bed is shorter than that a man can stretch himself on it." (Isa. Xxviii. 20) 2. Not extended in time; having very limited duration; not protracted; as, short breath. "The life so short, the craft so long to learn." (Chaucer) "To short absense I could yield." (Milton) 3. Limited in quantity; inadequate; insufficient; scanty; as, a short supply of provisions, or of water. 4. Insufficiently provided; inadequately supplied; scantily furnished; lacking; not coming up to a resonable, or the ordinary, standard; usually with of; as, to be short of money. "We shall be short in our provision." (Shak) 5. Deficient; defective; imperfect; not coming up, as to a measure or standard; as, an account which is short of the trith. 6. Not distant in time; near at hand. "Marinell was sore offended That his departure thence should be so short." (Spenser) "He commanded those who were appointed to attend him to be ready by a short day." (Clarendon) 7. Limited in intellectual power or grasp; not comprehensive; narrow; not tenacious, as memory. "Their own short understandings reach No farther than the present." (Rowe) 8. Less important, efficaceous, or powerful; not equal or equivalent; less (than); with of. "Hardly anything short of an invasion could rouse them again to war." (Landor) 9. Abrupt; brief; pointed; petulant; as, he gave a short answer to the question. 10. Breaking or crumbling readily in the mouth; crisp; as, short pastry. 11. <chemistry> Brittle. Metals that are brittle when hot are called ot-short; as, cast iron may be hot-short, owing to the presence of sulphur. Those that are brittle when cold are called cold-short; as, cast iron may be cold-short, on account of the presence of phosphorus. 12. Engaging or engaged to deliver what is not possessed; as, short contracts; to be short of stock. See The shorts, under Short, and To sell short. In mercantile transactions, a note or bill is sometimes made payable at short sight, that is, in a little time after being presented to the payer. 13. Not prolonged, or relatively less prolonged, in utterance; opposed to long, and applied to vowels or to syllables. In English, the long and short of the same letter are not, in most cases, the long and short of the same sound; thus, the i in ill is the short sound, not of i in isle, but of ee in eel, and the e in pet is the short sound of a in pate, etc. See Quantity, and Guide to Pronunciation, 22. Short is much used with participles to form numerous self-explaining compounds; as, short-armed, short-billed, short-fingered, short-haired, short-necked, short-sleeved, short-tailed, short-winged, short-wooled, etc. at short notice, in a brief time; promptly. Short rib, any suit having only three cards, or less than three. To come short, To cut short, To fall short, etc. See Come, Cut, etc. Origin: OE. Short, schort, AS. Scort, sceort; akin to OHG. Scurz, Icel. Skorta to be short of, to lack, and perhaps to E. Shear, v. T. Cf. Shirt. Source: Websters Dictionary (01 Mar 1998) |
