| resins | Flammable, amorphous, vegetable products of secretion or disintegration, usually formed in special cavities of plants. They are generally insoluble in water and soluble in alcohol, carbon tetrachloride, ether, or volatile oils. They are fusible and have a conchoidal fracture. They are the oxidation or polymerization products of the terpenes, and are mixtures of aromatic acids and esters. most are soft and sticky, but harden after exposure to cold. (12 Dec 1998) |
| resins, synthetic | Polymers of high molecular weight which at some stage are capable of being molded and then harden to form useful components. (12 Dec 1998) |
| resist | A substance used to prevent a colour or mordant from fixing on those parts to which it has been applied, either by acting machanically in preventing the colour, etc, from reaching the cloth, or chemically in changing the colour so as to render it incapable of fixing itself in the fibres. The pastes prepared for this purpose are called resist pastes. Source: Websters Dictionary (01 Mar 1998) |
| resistance | The failure of a condition to respond or remit following treatment. (16 Dec 1997) |
| resistance factor | <molecular biology> A self-replicating fragment of nucleic acid that confers drug resistance and is transmitted from one bacterium to another via conjugation. (09 Oct 1997) |
| resistance factors | Plasmid's carrying genes responsible for antibiotic (or antibacterial drug) resistance among bacteria (notably Enterobacteriaceae); they may be conjugative or nonconjugative plasmid's, the former possessing transfer genes (resistance transfer factor) lacking in the latter. Synonym: R factors, R plasmids, resistance factors, resistance-transferring episomes. (05 Mar 2000) |
| resistance form | The shape given to a cavity preparation that enables the dental restoration to withstand masticatory forces. (05 Mar 2000) |
| resistance plasmids | Plasmid's carrying genes responsible for antibiotic (or antibacterial drug) resistance among bacteria (notably Enterobacteriaceae); they may be conjugative or nonconjugative plasmid's, the former possessing transfer genes (resistance transfer factor) lacking in the latter. Synonym: R factors, R plasmids, resistance factors, resistance-transferring episomes. (05 Mar 2000) |
| resistance pyrometer | A device measuring temperature by the change of the electrical resistance of a metal wire. Synonym: resistance pyrometer. (05 Mar 2000) |
| resistance thermometer | A device measuring temperature by the change of the electrical resistance of a metal wire. Synonym: resistance pyrometer. (05 Mar 2000) |
| resistance, antibiotic | The ability of bacteria and other microorganisms to withstand an antibiotic to which they were once sensitive (and were once stalled or killed outright). Also called drug resistance. (12 Dec 1998) |
