| high output failure | Heart failure in which, despite relative myocardial insufficiency and consequent congestive heart failure, the cardiac output is maintained at normal or supernormal levels, as is sometimes seen in emphysema, thyrotoxicosis, etc. (05 Mar 2000) |
| high-palmed | <zoology> Having high antlers; bearing full-grown antlers aloft. Source: Websters Dictionary (01 Mar 1998) |
| high-pass filter | A device or material that allows high frequency signals to pass while attenuating other signals. (05 Mar 2000) |
| high-performance liquid chromatography | <investigation> A lab technique, a type of column chromatography, which uses a combination of several separation techniques to separate substances at higher resolution. Extremely sharp peaks on the elution profile can be produced with high-performance liquid chromatography (HPLC). (09 Oct 1997) |
| high-pressure | 1. Having or involving a pressure greatly exceeding that of the atmosphere; said of steam, air, water, etc, and of steam, air, or hydraulic engines, water wheels, etc. 2. Urgent; intense; as, a high-pressure business or social life. High-pressure engine, an engine in which steam at high pressure is used. It may be either a condensing or a noncondensing engine. Formerly the term was used only of the latter. See Steam engine. Source: Websters Dictionary (01 Mar 1998) |

| high pressure nervous syndrome | <syndrome> A syndrome of tremors, nausea, dizziness, and decreased motor and mental performance which develops in those who dive deeply (c. 1000 ft) usually breathing a mixture of oxygen and helium. Nitrogen is not a factor as it is in inert gas narcosis. (12 Dec 1998) |

| high quality filter paper | Used in paper chromatography. Synonym: high quality filter paper. Congo red paper, paper impregnated with Congo red; used as a pH indicator, changing from blue-violet at 3.0 to red at 5.0. Filter paper, an unsized paper used in pharmacy and chemistry for filtering solutions; many varieties are used for paper chromatography. (05 Mar 2000) |
| high-resolution banding | Banding, especially in prophase, which increases the clarity and number of discernible chromosome bands. (05 Mar 2000) |
| high resolution computed tomography | Computed tomography with narrow collimation to reduce volume-averaging and an edge-enhancing reconstruction algorithm to sharpen the image, sometimes with a restricted field of view to minimise the size of pixels in the region imaged; used particularly for lung imaging. Hypocycloidal tomography, body section radiography using a complex film and tube motion with a pattern resembling a three-leaf clover. (05 Mar 2000) |
| high-resolution imaging | <technique> High Resolution Electron Microscopy is phase contrast microscopy of the atomic structure of materials. In most crystalline inorganic materials and a number of polymeric materials HREM allows the imaging of individual atomic columns. The images can frequently be interpreted in terms of the projected crystal potential, although it is often necessary to match the experimental images with those calculated from multislice algorithms. Allows direct measurement of lattice parameters, inspection of individual defects and grain orientation. (05 Aug 1998) |
