| anion exchanger | Family of Integral membrane proteins that perform the exchange of chloride and bicarbonate across the plasma membrane. Best known is Band III protein of the red blood cell. (18 Nov 1997) |
|---|---|
| cation exchanger | An insoluble solid (usually a polystyrene or a polysaccharide) that has negatively charged radicals attached to it (e.g., -COO-, -SO3-), which can attract and hold cations that pass by in a moving solution if these are more attracted to the acid groups than the counter ion present. (05 Mar 2000) |
| countercurrent exchanger | A system in which heat or chemicals passively diffuse across a membrane separating two countercurrent exchanger streams so that at each end the fluid leaving along one side of the membrane nearly resembles, in temperature or composition, the fluid entering the other; e.g., the venae comites in the arms serve as a countercurrent exchanger exchanger, the arterial blood serving to rewarm the cooler venous blood. (05 Mar 2000) |
| sodium-calcium exchanger | An electrogenic ion exchange protein that maintains a steady level of calcium by removing an amount of calcium equal to that which enters the cells. It is widely distributed in most excitable membranes, including the brain and heart. (12 Dec 1998) |
| ion exchanger | See: anion exchanger, cation exchanger. (05 Mar 2000) |
| atomic heat | The amount of heat required to raise an atom from 0 |
| radiant heat | Heat given off from any body in the form of waves, similar to light waves but of greater wavelength. (05 Mar 2000) |
| molar heat capacity | <chemistry> The amount of energy required to raise the temperature of one mole of a substance by one degree Celsius (or Kelvin). (09 Jan 1998) |
| molecular heat | The product of the specific heat of a body multiplied by its molecular weight. (05 Mar 2000) |
| combined heat and power | An older term for what is now generally called cogeneration. The term is currently used in Europe and other foreign countries. (05 Dec 1998) |
| conductive heat | Heat transmitted by direct contact, as by an electric pad or hot water bottle. (05 Mar 2000) |
| convective heat | Heat conveyed by a warm medium, such as air or water, in motion from its source. (05 Mar 2000) |
| conversive heat | Heat produced in a body by the absorption of waves that are not in themselves hot, such as the sun's rays or infrared radiation. (05 Mar 2000) |
| prickly heat | An eruption of papules and vesicles at the orifices of sweat glands, accompanied by redness and inflammatory reaction of the skin. Synonym: heat rash, lichen infantum, lichen strophulosus, prickly heat, strophulus, summer rash, tropical lichen, lichen tropicus, wildfire rash. (05 Mar 2000) |
| heat | <chemistry> Energy transferred between two objects because of a temperature difference, the thermal motion of atoms and molecules. For chemical systems the sign for heat flow into the system is positive, because this process increases the internal energy of the system. Heat flowing out of the system is defined to be negative, since this process decreases the internal energy of the system. (09 Jan 1998) |

| heat exchanger |
a device in which heat is transferred by conduction through a metal barrier from a hotter liquid or gas, to warm a cooler liquid or gas on the other side of the metal barrier. Types of heat exchangers include "shell and tube," and "plate."
