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..

Wheel :: Wheel (n.) A firework which, while burning, is caused to revolve on an axis by the reaction of the escaping gases..

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..

Reaction :: Reaction (n.) Backward tendency or movement after revolution, reform, or great progress in any direction..

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

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

Coagulation :: Coagulation (n.) The change from a liquid to a thickened, curdlike, insoluble state, not by evaporation, but by some kind of chemical reaction; as, the spontaneous coagulation of freshly drawn blood; the coagulation of milk by rennet, or acid, and the coagulation of egg albumin by heat. Coagulation is generally the change of an albuminous body into an insoluble modification..

Reactionary :: Reactionary (n.) One who favors reaction, or seeks to undo political progress or revolution..

Lactucin :: Lactucin (n.) A white, crystalline substance, having a bitter taste and a neutral reaction, and forming one of the essential ingredients of lactucarium..

Bile :: Bile (n.) A yellow, or greenish, viscid fluid, usually alkaline in reaction, secreted by the liver. It passes into the intestines, where it aids in the digestive process. Its characteristic constituents are the bile salts, and coloring matters..

Catalysis :: Catalysis (n.) A process by which reaction occurs in the presence of certain agents which were formerly believed to exert an influence by mere contact. It is now believed that such reactions are attended with the formation of an intermediate compound or compounds, so that by alternate composition and decomposition the agent is apparenty left unchanged; as, the catalysis of making ether from alcohol by means of sulphuric acid; or catalysis in the action of soluble ferments (as diastase, or ptyali

Casein :: Casein (n.) A proteid substance present in both the animal and the vegetable kingdom. In the animal kingdom it is chiefly found in milk, and constitutes the main part of the curd separated by rennet; in the vegetable kingdom it is found more or less abundantly in the seeds of leguminous plants. Its reactions resemble those of alkali albumin..

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

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..

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..

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..

Earth :: Earth (n.) A similar oxide, having a slight alkaline reaction, as lime, magnesia, strontia, baryta..

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..

Reactionary :: Reactionary (a.) Being, causing, or favoring reaction; as, reactionary movements..

Resist :: Resist (v. t.) To counteract, as a force, by inertia or reaction..
