| electronic 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) |
| genetic load | <genetics> In general terms the decrease in fitness of a population (as a result of selection acting on phenotypes) due to deleterious mutations in the population gene pool. More specifically, the average number of recessive lethal mutations, in the heterozygous state, estimated to be present in the genome of an individual in a population. (18 Nov 1997) |
| viral load | The number of viral particles (usually HIV) in a sample of blood plasma. HIV viral load is increasingly employed as a surrogate marker for disease progression. It is measured by PCR and bDNA tests and is expressed in number of HIV copies or equivalents per millilitre. (09 Oct 1997) |
| Mueller electronic tonometer | A Schiotz type tonometer that electronically indicates the extent of corneal indentation; may also have an attached recorder for continuous pressure readings (tonography). (05 Mar 2000) |
| hydraulic load | Amount of liquid going into a system. (05 Dec 1998) |

| electronic | 1. Pertaining to electrons. 2. Denoting devices or systems utilizing the flow of electrons in a vacuum, gas, or saemiconductor. (05 Mar 2000) |
| electronic cell counter | <apparatus, haematology> An automatic blood cell counter in which cells passing through an aperture alter resistance and are counted as voltage pulses, or in which cells passing through a flow cell deflect light. Some types of counter are capable of multiple simultaneous measurements on each blood sample; e.g., leukocyte count, red cell count, haemoglobin, haematocrit, and red cell indices. (21 Jun 2000) |
| electronic number | <chemistry> The number of electrons in the outermost orbit (valence shell) of an element. (05 Mar 2000) |
| electronic potential | <chemistry, physiology> The measure (in volts) of electron pressure. A measure of the difference in electron concentrations between two compartments, such as either side of a cell membrane. (09 Oct 1997) |
| load | 1. To lay a load or burden on or in, as on a horse or in a cart; to charge with a load, as a gun; to furnish with a lading or cargo, as a ship; hence, to add weight to, so as to oppress or embarrass; to heap upon. "I strive all in vain to load the cart." (Gascoigne) "I have loaden me with many spoils." (Shak) "Those honors deep and broad, wherewith Your majesty loads our house." (Shak) 2. To adulterate or drug; as, to load wine. 3. To magnetize. Loaded dice, dice with one side made heavier than the others, so that the number on the opposite side will come up oftenest. Origin: Loaded; Loading. Loaden is obsolete, and laden belongs to lade. 1. A burden; that which is laid on or put in anything for conveyance; that which is borne or sustained; a weight; as, a heavy load. "He might such a load To town with his ass carry." (Gower) 2. The quantity which can be carried or drawn in some specified way; the contents of a cart, barrow, or vessel; that which will constitute a cargo; lading. 3. That which burdens, oppresses, or grieves the mind or spirits; as, a load of care. " A . . . Load of guilt." . " Our life's a load." 4. A particular measure for certain articles, being as much as may be carried at one time by the conveyance commonly used for the article measured; as, a load of wood; a load of hay; specifically, five quarters. 5. The charge of a firearm; as, a load of powder. 6. Weight or violence of blows. 7. <machinery> The work done by a steam engine or other prime mover when working. Load line, or Load water line, the line on the outside of a vessel indicating the depth to which it sinks in the water when loaded. Synonym: Burden, lading, weight, cargo. See Burden. Origin: OE. Lode load, way; properly the same word as lode, but confused with lade, load, v. See Lade, Lead, Lode. Source: Websters Dictionary (01 Mar 1998) |
| load factor | Load factor is the ratio of average demand to maximum demand or to capacity. (05 Dec 1998) |
| load management | Any method or device that evens out electric power demand by eliminating uses during peak periods or shifting usage from peak time to off-peak time. (05 Dec 1998) |
| artificial pacemaker | Any device that substitutes for the normal pacemaker and controls the rhythm of the organ; especially an electronic cardiac pacemaker, which may be implanted in the chest, with electrodes attached to the external cardiac surface, or passed through the venous circulation into the right side of the heart (pervenous pacemaker).
