Fluorescein (n.) A yellow dye that is visible even when highly diluted; used as an absorption indicator when silver nitrate solution is added to sodium chloride in order to precipitate silver chloride (turns pink when no chloride ions are left in solution and negative fluorescein ions are then absorbed) [syn: fluorescein, fluoresceine, fluorescent dye, resorcinolphthalein].
Fluorescence (n.) (Chemistry, Optics) A luminescence emitted by certain substances due to the absorption of radiation at one wavelength, and the almost instantaneous re-emission of radiation at another, usually longer wavelength. The re-radiation stops almost as soon as the incident radiation is halted, thus distinguishing this phenomenon from phosphorescence, in which re-radiation of light may continue for some time after the incident radiation is halted.
Note: The color of the radiated light typically differs from the apparent color of the material, as when green crystals of fluor spar afford blue reflections. It is due not to the difference in the color of a distinct surface layer, but to the power which the substance has of modifying the light incident upon it, by first absorbing the light to achieve an excited state, and then radiating light to resume the ground energy level.
The light emitted by fluorescent substances is in general of longer wavelength than the incident light.
The radiation can also be induced by ionizing radiation which is not electromagnetic, such as alpha or beta rays, and cathode rays. This property is possessed by fluorspar, uranium glass, sulphide of calcium, and many other substances. It finds use in analytical instruments to detect or measure radiation, and in some commercial applications.
Fluorescence (n.) Light emitted during absorption of radiation of some other (invisible) wavelength.
Fluorescent (a.) Having the property of fluorescence.
Fluorescent (a.) Emitting light during exposure to radiation from an external source.

Fluoride (n.) (Chem.) A binary compound of fluorine with another element or radical.
Calcium fluoride (Min.), Fluorite, CaF2. See Fluorite.
Fluoride (n.) A salt of hydrofluoric acid.
Fluorine (n.) (Chem.) A non-metallic, gaseous element, strongly acid or negative, or associated with chlorine, bromine, and iodine, in the halogen group of which it is the first member. It always occurs combined, is very active chemically, and possesses such an avidity for most elements, and silicon especially, that it can neither be prepared nor kept in glass vessels. If set free it immediately attacks the containing material, so that it was not isolated until 1886. It is a pungent, corrosive, colorless gas. Symbol F. Atomic weight 19.00.
Note: Fluorine unites with hydrogen to form hydrofluoric acid, which is the agent employed in etching glass. It occurs naturally, principally combined as calcium fluoride in fluorite, and as a double fluoride of aluminium and sodium in cryolite.
Fluorine (n.) A nonmetallic univalent element belonging to the halogens; usually a yellow irritating toxic flammable gas; a powerful oxidizing agent; recovered from fluorite or cryolite or fluorapatite [syn: fluorine, F, atomic number 9].

?Flush? was standard ITS terminology for aborting an output operation; one spoke of the text that would have been printed, but was not, as having been flushed. It is speculated that this term arose from a vivid image of flushing unwanted characters by hosing down the internal output buffer, washing the characters away before they could be printed. The Unix/C usage, on the other hand, was propagated by the fflush(3) call in C's standard I/O library (though it is reported to have been in use among BLISS programmers at DEC and on Honeywell and IBM machines as far back as 1965). Unix/C hackers found the ITS usage confusing, and vice versa.
[crunchly-5]

Flush, () To delete something, usually superfluous, or to abort an operation.
"Flush" was standard ITS terminology for aborting an output operation. One spoke of the text that would have been printed, but was not, as having been flushed. It is speculated that this term arose from a vivid image of flushing unwanted characters by hosing down the internal output buffer, washing the characters away before they could be printed.
Compare Drain.
Flush, () To force temporarily buffered data to be written to more permanent memory. E.g. flushing buffered disk writes to disk, as with C's standard I/O library "fflush(3)" call. This sense was in use among BLISS programmers at DEC and on Honeywell and IBM machines as far back as 1965. Another example of this usage is flushing a cache on a context switch where modified data stored in the cace which belongs to one processes must be written out to main memory so that the cache can be used by another process.
