"Thermal" Quotes from Famous Books



... more vigorous race, it set a high premium on colored blood. It has fostered and multiplied a vigorous black race, and engendered a feeble mulatto breed. Many of each of these classes have drifted northward, right in the teeth of thermal laws, to find homes where they would never live by natural election. Now, by utterly rooting out slavery, and by that means alone, shall we remove these disturbing forces and allow fair play to natural laws, by the operation of which, it seems to me, ...

... continuous, unlimited medium, without an atom in it. On this assumption it is clear that no form of energy with which we have to deal in physical science would have any existence in the ether; for every one of those forms, gravitational, thermal, electric, magnetic, or any other—all are the results of the forms of energy in matter. If there were no atoms, there would be no gravitation, for that is the attraction of atoms upon each other. If there were no atoms, ...

We had pretty bad storms right after transit a year ago; they'll be much worse this time. Thermal convections; air starts to cool when it gets dark, and then heats up again in ...

... iron, in part reflected, in part absorbed, in part transmitted, gradually raising the temperature of the water from normal to boiling point, a rise in temperature expressible as the result of an expenditure of 72 thermal units needed to raise 1 pound of water from 50 degrees to 212 ...

... character, are variegated with yellow, gray and brown, and the action of the water in its rapid passage down the sides of the canon has worn the fragments of shale into countless capricious forms. Jets of steam issue from the sides of the canon at frequent intervals, marking the presence of thermal springs and active volcanic forces. The evidence of a recession of the river through the canon is designated by the ridges apparent on its sides, and it is not improbable that at no distant day the lower fall will become blended by this process with the upper, forming a single cataract ...

... electro-chemical industries, for these industries could never otherwise develop into extended commercial applications. Of the total output of, say, 55,000 horse-power at the Niagara Falls generating plant, no less than 23,200 horse-power is used in various electrolytic and electro-thermal processes in the immediate neighborhood. Some of the more important consumers of the electric power, named in the order of consumption, are for the manufacture of the following products: calcium carbide, aluminium, caustic soda and bleaching ...

... resistance occurs with corresponding localization of heating effect. This is the cause of the intense light. Thus if the carbons are but 1/32 of an inch apart as in a commercial lamp the resistance may be 1.5 ohms. The poor thermal conductivity of the carbon favors the concentration of heat also. The apparent resistance is too great to be accounted for by the ohmic resistance of the interposed air. A kind of thermoelectric effect is produced. The positive carbon has a temperature ...

... delivered by pipeline from Azerbaijan to the port of Batumi for export and local refining. Gas is supplied in pipelines from Krasnodar and Stavropol'. Georgia is nearly self-sufficient in electric power, thanks to abundant hydropower stations as well as some thermal power stations. The dismantling of central economic controls is being delayed by political factionalism, marked by armed struggles between the elected government and the opposition, and industrial output seems to have fallen more steeply ...

... and rupture of the choroid, paralysis of the oculomotor muscles, and paralysis of the optic nerve. According to Buller of Montreal, such injuries may arise from the mechanic violence sustained by the patient rather than by the thermal or chemic action of the current. Buller describes a case of lightning-stroke in which the external ocular muscles, the crystalline lens, and the optic nerve were involved. Godfrey reports the case of Daniel ...

... toxins—and they are essentially similar in kind whatever the irritant may be. The extent to which the process may go, however, and its effects on the part implicated and on the system as a whole, vary with different irritants and with the intensity and duration of their action. A mechanical, a thermal, or a chemical irritant, acting alone, induces a degree of reaction directly proportionate to its physical properties, and so long as it does not completely destroy the vitality of the part involved, the changes ...
