| gun | 1. A weapon which throws or propels a missile to a distance; any firearm or instrument for throwing projectiles by the explosion of gunpowder, consisting of a tube or barrel closed at one end, in which the projectile is placed, with an explosive charge behind, which is ignited by various means. Muskets, rifles, carbines, and fowling pieces are smaller guns, for hand use, and are called small arms. Larger guns are called cannon, ordnance, fieldpieces, carronades, howitzers, etc. See these terms in the Vocabulary. "As swift as a pellet out of a gunne When fire is in the powder runne." (Chaucer) "The word gun was in use in England for an engine to cast a thing from a man long before there was any gunpowder found out." (Selden) 2. A piece of heavy ordnance; in a restricted sense, a cannon. 3. Violent blasts of wind. Guns are classified, according to their construction or manner of loading as rifled or smoothbore, breech-loading or muzzle-loading, cast or built-up guns; or according to their use, as field, mountain, prairie, seacoast, and siege guns. Armstrong gun, a wrought iron breech-loading cannon named after its English inventor, Sir William Armstrong. Great gun, a piece of heavy ordnance; hence (Fig), a person superior in any way. Gun barrel, the barrel or tube of a gun. Gun carriage, the carriage on which a gun is mounted or moved. <medicine> Gun cotton, to blow a gale. See Gun. Origin: OE.

| soluble gun cotton | <chemistry> A substance resembling gun cotton in composition and properties, but distinct in that it is more highly nitrified and is soluble in alcohol, ether, etc. Synonym: pyroxyle. Source: Websters Dictionary (01 Mar 1998) |
| electron gun | <apparatus> A cathode/anode device intended to produce a stream of electrons. Also used inside a video camera tube and monitor picture tube that contains a heated cathode. Electrons emitted by the gun are focused to produce the scanning beam. (05 Aug 1998) |
| balanced stock | <genetics> A genetic strain of any of several lab organisms (like fruit flies) which can be maintained as heterozygous individuals without requiring constant artificial selection for the heterozygotes, due to a number of lethal recessive genes with the result that the homozygous females are sterile (unable to produce offspring) and the males with the wrong recessive alleles are dead. (Male fruit flies are not homozygous or heterozygous because they only have one allele per particular genetic loci in question). (09 Oct 1997) |

| frozen stock | <cell culture> Because cell lines tend to change their properties with continuous rounds of subculturing, it is common practice to keep stocks of cells frozen (either in liquid nitrogen or at 70_C) and to keep returning to this stock so that experiments are all carried out on cells of comparable passage number. The method also allows strains to be stored for long periods. Cells are usually frozen down in the presence of a cryoprotectant such as DMSO or glycerol. The method is also extensively used for storing semen for artificial insemination. (18 Nov 1997) |
