| mass stopping power | <physics> The mass stopping power (S/r) of a material for charged particles is the quotient dEs by the product of dl and r, where dEs is the average energy lost by a charged particle of specified energy in traversing a path length dl and r is the density of the medium. (16 Dec 1997) |

| pitch angle scattering | <physics> Scattering (collisional, or due to wave-particle effects) of particles in velocity space, in which the pitch angle (see entry above) is changed. (09 Oct 1997) |
| Compton scattering | <radiobiology> An attenuation process observed for x and gamma radiation in which an incident photon interacts with an orbital electron of an atom to produce a recoil electron and a scattered photon of energy less than the incident photon. (16 Dec 1997) |
| scattering | <radiobiology> The deflection of one particle as a result of collisions with other particles or with waves. See: Elastic. (09 Oct 1997) |
| scattering, radiation | The process in which energy is removed from a beam of light or other electromagnetic radiation and emitted without appreciable change in wavelength. May be considered as the change in direction of a particle or photon owing to a collision with another particle or system. (12 Dec 1998) |
| Thomson scattering | <radiobiology> Scattering of photons by electrons, in the classical (low photon energy) limit. Laser light passed through a plasma will experience Thomson scattering, the spread of the scattered light in energy provides a very good measurement of the electron temperature of the plasma. (09 Oct 1997) |
| light scattering | Particles suspended in a solution will cause scattering of light and the extent of the scattering is related to the size and shape of the particles (in a somewhat complex relationship). (18 Nov 1997) |
| candle-power | The luminous flux per unit solid angle in a given direction. Synonym: candle-power, radiant intensity. (05 Mar 2000) |
| resolving power | 1. <optics> The resolution of an optical system defines the closest proximity of two objects that can be seen as two distinct regions of the image. This limit depends upon the Numerical Aperture of the optical system, the contrast step between objects and background and the shape of the objects. The often quoted Airy limit applies only to self luminous discs. 2. <genetics> The smallest map distance measurable by an experiment involving a certain number of classified recombinant progency. (10 Mar 1998) |
| combined-cycle power plant | The combination of a gas turbine and a steam turbine in an electric generation plant. The waste heat from the gas turbine provides the heat energy for the steam turbine. (05 Dec 1998) |
| 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) |
| condensing power | Power generated through a final steam turbine stage where the steam is exhausted into a condenser and cooled to a liquid to be recycled back into a boiler. (05 Dec 1998) |
| polarizing power | <chemistry> Means that a charged species such as a proton can attract negatively charged electrons which causes a shift in the orbital. The higher the positive charge and the smaller the smaller the size, the greater the polarizing power of the species. (09 Jan 1998) |
| power | 1. Ability, regarded as put forth or exerted; strength, force, or energy in action; as, the power of steam in moving an engine; the power of truth, or of argument, in producing conviction; the power of enthusiasm. The agent exercising an ability to act; an individual invested with authority; an institution, or government, which exercises control; as, the great powers of Europe; hence, often, a superhuman agent; a spirit; a divinity. 2. <psychology> The exertion of a strong influence or control over others in a variety of settings; administrative, social, academic, etc. Mental or moral ability to act; one of the faculties which are possessed by the mind or soul; as, the power of thinking, reasoning, judging, willing, fearing, hoping, etc. 3. <mechanics> The rate at which mechanical energy is exerted or mechanical work performed, as by an engine or other machine, or an animal, working continuously; as, an engine of twenty horse power. Applied force; force producing motion or pressure; as, the power applied at one and of a lever to lift a weight at the other end. 4. <unit> The English unit of power used most commonly is the horse power. See Horse power. 5. <mathematics> The product arising from the multiplication of a number into itself; as, a square is the second power, and a cube is third power, of a number. 6. <optics> The degree to which a lens, mirror, or any optical instrument, magnifies; in the telescope, and usually in the microscope, the number of times it multiplies, or augments, the apparent diameter of an object; sometimes, in microscopes, the number of times it multiplies the apparent surface. 7. Power may be predicated of inanimate agents, like the winds and waves, electricity and magnetism, gravitation, etc, or of animal and intelligent beings; and when predicated of these beings, it may indicate physical, mental, or moral ability or capacity. 8. <geometry> Power of a point (relative to a given curve), the result of substituting the coordinates of any point in that expression which being put equal to zero forms the equation of the curve; as, x^2 + y^2 - 100 is the power of the point x, y, relative to the circle x^2 + y^2 - 100 = 0. Origin: OE. Pouer, poer, OF. Poeir, pooir, F. Pouvoir, n. & v, fr. LL. Potere, for L. Posse, potesse, to be able, to have power. See Possible, Potent, and cf. Posse comitatus.
