Reaction :: Reaction (n.) The mutual or reciprocal action of chemical agents upon each other, or the action upon such chemical agents of some form of energy, as heat, light, or electricity, resulting in a chemical change in one or more of these agents, with the production of new compounds or the manifestation of distinctive characters. See Blowpipe reaction, Flame reaction, under Blowpipe, and Flame..

Barker''s Mill :: Barker's mill () A machine, invented in the 17th century, worked by a form of reaction wheel. The water flows into a vertical tube and gushes from apertures in hollow horizontal arms, causing the machine to revolve on its axis..

Xanthoproteic :: Xanthoproteic (a.) Pertaining to, or derived from, xanthoprotein; showing the characters of xanthoprotein; as, xanthoproteic acid; the xanthoproteic reaction for albumin..

Electro-muscular :: Electro-muscular (a.) Pertaining the reaction (contraction) of the muscles under electricity, or their sensibility to it..

Coagulate :: Coagulate (v. t.) To cause (a liquid) to change into a curdlike or semisolid state, not by evaporation but by some kind of chemical reaction; to curdle; as, rennet coagulates milk; heat coagulates the white of an egg..

Lactamide :: Lactamide (n.) An acid amide derived from lactic acid, and obtained as a white crystalline substance having a neutral reaction. It is metameric with alanine..

Sequence :: Sequence (n.) Simple succession, or the coming after in time, without asserting or implying causative energy; as, the reactions of chemical agents may be conceived as merely invariable sequences..

Turbine :: Turbine (n.) A water wheel, commonly horizontal, variously constructed, but usually having a series of curved floats or buckets, against which the water acts by its impulse or reaction in flowing either outward from a central chamber, inward from an external casing, or from above downward, etc.; -- also called turbine wheel..

Water Wheel :: Water wheel () Any wheel for propelling machinery or for other purposes, that is made to rotate by the direct action of water; -- called an overshot wheel when the water is applied at the top, an undershot wheel when at the bottom, a breast wheel when at an intermediate point; other forms are called reaction wheel, vortex wheel, turbine wheel, etc..

Reflux :: Reflux (n.) A flowing back, as the return of a fluid; ebb; reaction; as, the flux and reflux of the tides..

Reflex :: Reflex (a.) Produced in reaction, in resistance, or in return..

Passive :: Passive (a.) Designating certain morbid conditions, as hemorrhage or dropsy, characterized by relaxation of the vessels and tissues, with deficient vitality and lack of reaction in the affected tissues..

Test :: Test (n.) A reaction employed to recognize or distinguish any particular substance or constituent of a compound, as the production of some characteristic precipitate; also, the reagent employed to produce such reaction; thus, the ordinary test for sulphuric acid is the production of a white insoluble precipitate of barium sulphate by means of some soluble barium salt..

Rational :: Rational (a.) Expressing the type, structure, relations, and reactions of a compound; graphic; -- said of formulae. See under Formula..

Acid :: Acid (a.) Of or pertaining to an acid; as, acid reaction..

Abutment :: Abutment (n.) A fixed point or surface from which resistance or reaction is obtained, as the cylinder head of a steam engine, the fulcrum of a lever, etc..

Strook :: Strontium (n.) A radioactive isotope of strontium produced by certain nuclear reactions, and constituting one of the prominent harmful components of radioactive fallout from nuclear explosions; also called radiostrontium. It has a half-life of 28 years..
