|---|---|
| genes, regulator | Genes which regulate or circumscribe the activity of other genes; specifically, genes which code for proteins (repressors or activators) which regulate the genetic transcription of the structural genes and/or regulatory genes. (12 Dec 1998) |
| regulator | A substance or process that regulates another substance or process. Growth regulators, substances that can alter the growth of a living organism. (05 Mar 2000) |
| regulator gene | A gene that produces a repressor substance that inhibits an operator gene when combined with it. It thus prevents production of a specific enzyme. When the enzyme is again in demand, a specific regulatory metabolite inhibits the repressor substance. (05 Mar 2000) |
| cystic fibrosis transmembrane conductance regulator | Gene believed to be defective in cystic fibrosis. Gene encodes a chloride channel, homologous to a family of proteins that actively transport small solutes in an ATP dependent manner (ABC transporters). The regulator protein is a protein which is embedded in the cell membrane and acts as a channel for certain ions to be transported into or out of the cell. The disease cystic fibrosis is caused by a defect in the gene for this protein. (09 Oct 1997) |
| radio frequency heating | <radiobiology> Process for heating the plasma by transferring energy to ions or electrons using waves generated by an external oscillator at an appropriate frequency. (This is similar to how a microwave oven heats food.) There are various types: See: ECRH, ICRH, and Lower Hybrid. (09 Oct 1997) |
| gross heating value | (GHV) The maximum potential energy in the fuel as received. It reflects the displacement of fibre by water present in the fuel. Expressed as: GHV = HHV (1 - MC / 100) (05 Dec 1998) |
| heating | That heats or imparts heat; promoting warmth or heat; exciting action; stimulating; as, heating medicines or applications. Heating surface, the aggregate surface exposed to fire or to the heated products of combustion, especially. Of all the plates or sheets that are exposed to water on their opposite surfaces. Synonym: fire surface. Source: Websters Dictionary (01 Mar 1998) |
| heating curve | <chemistry> A plot of temperature verses time for a substance where energy is added at a constant rate. (09 Jan 1998) |
| heating value | The maximum amount of energy that is available from burning a substance. (05 Dec 1998) |
| higher heating value | (HHV) The maximum potential energy in dry fuel. For wood, the range is 7,600 to 9,600 Btu/lb. (05 Dec 1998) |
| net heating value | The potential energy available in the fuel as received, taking into account the energy loss in evapourating and superheating the water in the sample. Expressed as NVH = (HHV x (1- MC / 100)) - (LH(2)O x MC / 100) (05 Dec 1998) |
| district heating or cooling | A system that involves the central production of hot water, steam, or chilled water and the distribution of these transfer media to heat or cool buildings. (05 Dec 1998) |
| electron cyclotron heating | <physics, radiobiology> Radiofrequency heating scheme that works by injecting electromagnetic wave energy at the electron cyclotron gyration frequency. The electric field of the electromagnetic wave at this frequency looks to a gyrating electron like a static electric field, and thus causes large acceleration of the electron (larger than if the frequency were off the cyclotron frequency and thus, to the electron, appearing to change direction as a function of time). The accelerated electron gains energy, which is then shared with other particles through collisions, resulting in heating. Higher harmonics (multiples) of the cyclotron frequency can also be used in principle. (09 Oct 1997) |
| turbulent heating | <radiobiology> Technique of using turbulence induced by large electric fields to rapidly heat a plasma, the turbulence increases the resistivity of the plasma. (09 Oct 1997) |
