| excitatory postsynaptic potential | The change in potential which is produced in the membrane of the next neuron when an impulse which has an excitatory influence arrives at the synapse; it is a local change in the direction of depolarisation; summation of these potential's can lead to discharge of an impulse by the neuron. (05 Mar 2000) |
|---|---|
| junction potential | <physiology> Potential difference at the boundary between dissimilar solutions, arises from differences in diffusion constants between ions. (18 Nov 1997) |
| years of potential life lost | Measure of the relative impact of various diseases and lethal forces on society, computed by estimating the years that people would have lived if they had not died prematurely from injury, cancer, heart disease, etc. (05 Mar 2000) |
| zeta potential | <chemistry> The electrostatic potential of a molecule or particle, for example cell measured at the plane of hydrodynamic slippage outside the surface of the molecule or cell. Usually measured by electrophoretic mobility. Related to the surface potential and a measure of the electrostatic forces of repulsion the particle or molecule is likely to meet when encountering another of the same sign of charge. See: cell electrophoresis. (18 Nov 1997) |
| zoonotic potential | The potential for infections of subhuman animals to be transmissible to humans. (05 Mar 2000) |
| low malignant potential tumour | A neoplasm of the ovary, usually arising in young women, composed of complex epithelial hyperplasia without stromas invasion; may recur if incompletely removed surgically, but is clinically less aggressive than carcinoma. Synonym: low malignant potential tumour. (05 Mar 2000) |
| activation energy | <chemistry> The amount of energy (expressed in joules) that is needed to convert all the molecules in one mole of a reacting substance from a ground state to the transition state. (06 May 1997) |
| binding energy | <chemistry, radiobiology> The binding energy of a nucleus is the minimum energy required to dissociate it into its component neutrons and protons. Neutron or proton binding energies are those required to remove a neutron or proton, respectively, from a nucleus. Electron binding energy is that required to remove an electron from an atom or a molecule. (16 Dec 1997) |
| bioelectric energy sources | Implantable devices which convert biological energy (chemical energy of the metabolism of continuously regenerating body fluids or mechanical energy of periodic movements) to electrical energy. The sources include biogalvanic cells, biofuel cells, and ionic concentration cells. (12 Dec 1998) |
| biomass energy | See Bioenergy. (05 Dec 1998) |
| bond dissociation energy | This is the energy needed to break the bonds between two linked atoms. (09 Oct 1997) |
| bond energy | The energy needed to break a molecular bond. (09 Oct 1997) |
| radiant energy | Energy contained in light rays or any other form of radiation. (05 Mar 2000) |
| radiography, dual-energy scanned projection | A method of producing a high-quality scan by digitizing and subtracting the images produced by high- and low-energy X-rays. (12 Dec 1998) |
| radiotherapy, high-energy | Radiotherapy using high-energy (megavolt or higher) ionizing radiation. Types of radiation include gamma rays, produced by a radioisotope within a teletherapy unit; X-rays, electrons, protons, alpha particles (helium ions) and heavy charged ions, produced by particle acceleration; and neutrons and pi-mesons (pions), produced as secondary particles following bombardment of a target with a primary particle. (12 Dec 1998) |
| potential energy |
is the energy an object has by virtue of its position. The gravitational potential energy of an object of mass m that is a height h above some reference level is PE = mgh, where g is the acceleration of gravity. Since mg is the object's weight w, an alternative formula is PE = wh.

| potential energy |
The energy of a body that is derived from its position, rather than motion, with respect to a specified datum in a field of force. The ability of a body to do work by virtue of its position.

| potential energy |
Potential energy is the energy possessed by an object because of its height above the ground. The amount of potential energy possessed by an object depends on its mass and its height. A roller coaster car is initially hauled by a motor and chain system to the top of a tall hill, giving it a large quantity of potential energy.

| potential energy |
The type on energy a coaster train has when it is on a high section of track, but not necessarily travelling very fast. A train's potential energy is jointly proportional to its mass and height.
