| liquid-liquid chromatography | Chromatography in which both the moving phase and the stationary (or reverse-moving) phase are liquids, as in countercurrent distribution. (05 Mar 2000) |

| pericardial friction sound | A to-and-fro grating, rasping, or, rarely, creaking sound heard over the heart in some cases of pericarditis, due to rubbing of the inflamed pericardial surfaces as the heart contracts and relaxes; during normal sinus rhythm it is usually triphasic; during any rhythm it may be biphasic or uniphasic. Synonym: pericardial rub, pericardial friction rub. (05 Mar 2000) |
| pleural friction rub | Friction rub sound caused by inflammation of the pleura. Synonym: pleural friction rub, pleural rale. (05 Mar 2000) |
| starting friction | The force that must be overcome to initiate the motion of one body relative to another because they have been resting in contact. Compare: dynamic friction. Synonym: static friction. (05 Mar 2000) |
| static friction | The force that must be overcome to initiate the motion of one body relative to another because they have been resting in contact. Compare: dynamic friction. Synonym: static friction. (05 Mar 2000) |
| dynamic friction | The force that must be overcome to maintain steady motion of one body relative to another because they remain in contact. Compare: starting friction. (05 Mar 2000) |
| friction | Surface resistance to the relative motion of one body against the rubbing, sliding, rolling, or flowing of another with which it is in contact. (12 Dec 1998) |
| friction murmur | The sound, heard on auscultation, made by the rubbing of two opposed serous surfaces roughened by an inflammatory exudate, or, if chronic, by nonadhesive fibrosis. Synonym: friction murmur, friction rub. (05 Mar 2000) |

| gas-liquid chromatography | <technique> A chemistry lab technique, a type of column chromatography, used to separate the components of a mixed substance. The substance is held stationary by an inert solid coated with an inert liquid which is not likely to evaporate (i.e. Is nonvolatile), while a gas (called an eluant) flows past it bringing out the components one at a time. (09 Oct 1997) |
| chromatography, high pressure liquid | Liquid chromatographic techniques which feature high inlet pressures, high sensitivity, and high speed. (12 Dec 1998) |
| chromatography, liquid | Chromatographic techniques in which the mobile phase is a liquid. (12 Dec 1998) |
| clear liquid diet | A diet, often used postoperatively, consisting usually of water, tea, coffee, gelatin preparations, and clear soups or broth. (05 Mar 2000) |
| Cotunnius' liquid | <anatomy> The fluid which surrounds the membranous labyrinth of the internal ear, and separates it from the walls of the chambers in which the labyrinth lies. Source: Websters Dictionary (01 Mar 1998) |
