ETYM Latin diarrhoea, Greek diarroia, from diarrein to flow through; dia + rein to flow; akin to Eng. stream. Related to Stream.
(Alternate spelling: diarrhoea)
Frequent and watery bowel movements; SYN. diarrhoea, looseness of the bowels.
Excessive action of the bowels so that the feces are fluid or semifluid. It is caused by intestinal irritants (including some drugs and poisons), infection with harmful organisms (as in dysentery, salmonella, or cholera), or allergies.
Diarrhea is the biggest killer of children in the world. The World Health Organization estimates that 4.5 million children die each year from dehydration as a result of diarrheal disease in Third World countries. It can be treated by giving an accurately measured aqueous solution of salt and glucose by mouth in large quantities (salt water with sugar, to restore the electrolyte balance in the blood). Since most diarrhea is viral in origin, antibiotics are ineffective.
ETYM Latin fluxus, from fluere, fluxum, to flow: cf.French flux. Related to Fluent, Floss, Flush.
1. The total strength of a magnetic, electric, or radiation field over a given area.
2. A chemical used to aid the binding of solder to electrical conductors.
In soldering, a substance that improves the bonding properties of solder by removing contamination from metal surfaces and preventing their oxidation, and by reducing the surface tension of the molten solder alloy. For example, with solder made of lead-tin alloys, the flux may be resin, borax, or zinc chloride.In smelting, a substance that combines with the unwanted components of the ore to produce a fusible slag, which can be separated from the molten metal. For example, the mineral fluorite, CaF2, is used as a flux in iron smelting; it has a low melting point and will form a fusible mixture with substances of higher melting point such as silicates and oxides.A chemically- or physically-active formulation which has the ability to clean oxides and enables wetting of metals with solder.
1. A flow or discharge; SYN. fluxion.
2. A substance added to molten metals to bond with impurities that can then be readily removed.
3. In constant change.
4. The rate of flow of energy or particles across a given surface.
