"Thermal" Quotes from Famous Books



... 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 ...

... periastron was ninety years ago, and we've only been here for sixty-odd; all we have is verbal accounts from memory from the natives, probably garbled and exaggerated. 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 ...

... unnecessarily, because the sergeant had watched as he worked. "They've got detectors out. I could just barely pick up the pulses. But by the time they've been reflected back they'll be away below thermal noise-volume. I don't think even multiples could pick 'em out. I'm saying, sir, that I don't think they can detect us ...

... springs* [Supposing the mean temperature of the air at the elevation of the Momay springs to be 26 degrees or 28 degrees, which may be approximately assumed, and that, as some suppose, the heat of thermal springs is due to the internal temperature of the globe; then according to the law of increment of heat in descending (of 1 degree for fifty feet) we should find the temperature of 110 degrees at a depth of 4,100 feet, or at 11,900 feet above the level ...

... leeward coast. The downfall must, however, have diminished since the times when 'the blacks will tell you the wet weather lasts eleven months and twenty-nine days in the year.' The rains now begin with April and end in September. The position is south of the thermal equator (22 R. 81 5 F.), which runs north lat. 6 on the western coast, 15 in the interior, and 10 on the eastern seaboard. [Footnote: Berghaus, following Humboldt, places the probable equator of temperature (80 16') in N. lat. ...

... 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 ...

... and tools. We were rather surprised to find that the coal and lubricating oil for the engine room were purchased by the manager himself, but not at all surprised to learn that he had never heard of such a quantity as a British Thermal unit and that he had absolutely no records to show the kind of coal most efficient under his boilers. A little further investigation showed that each head of department had charge of the stores of materials and supplies for his department and gave them out to employees upon a mere ...

In the village-inn at which he stopped, a young girl came to wait upon him; and, at the first sight of her face, he felt his heart leap as it had never leaped before. So ...

... till evening, as its appearance was very inviting. Its FAUNA and FLORA, however, were poor in the extreme. The only specimens of quadrupeds, birds, fish and cetacea were a few wild boars, stormy petrels, albatrosses, perch and seals. Here and there thermal springs and chalybeate waters escaped from the black lava, and thin dark vapors rose above the volcanic soil. Some of these springs were very hot. John Mangles held his thermometer in one of them, and found the temperature ...

... habitual vents that have been active during the periods covered by history and tradition, must be numbered by thousands. There are still feebler manifestations of the volcanic forces—such as steam-jets, geysers, thermal and mineral waters, spouting saline and muddy springs, and mud volcanoes—that may be reckoned by millions. It is not improbable that these less powerful manifestations of the volcanic forces to a great extent make up in number what they want in individual energy; and ...

... and 1883, the epicentre is an elongated band, the axis of which, if produced, would pass through the centre of the old crater of Epomeo. Along the line of this band, occur the fumaroles of Monte Cito and Ignazio Verde and the thermal springs of the Rita and Capitello. These facts, as Professor Mercalli suggests, lead us to believe that the foci of the earthquakes coincide with a radial fracture of the volcano, the course of which, as traced by him, is represented by the ...

... are the great fishing grounds of the tunny. Once he had disembarked in the island of Pantellaria, situated halfway between Sicily and Africa. It was a very high, volcanic cone that came up in the midst of the strait and had at its base alkaline lakes, sulphurous fumes, thermal waters, and prehistoric constructions of great stone blocks similar to those in Sardinia and the Balearic Islands. Boats bound for Tunis and Tripoli used to carry cargoes of raisins, the only export ...

Ten miles to the N.W. of Cilli are situated the baths of Neuhaus, with indifferent thermal waters (117 deg. F.), frequented by ladies. Not far from it is the ruined castle of Neuhaus, called since 1643 Schlangenburg, from which an extensive view of the neighbouring Alps ...

... the bedded rocks, which have taken the place of the igneous materials beneath, as a part of the rigid crust of the Earth, must be less able to withstand compressive stress than the average crust. For there has been no absolute rise of the geotherms, the thermal conductivities of both classes of materials differing but little. Sedimentary rock has merely taken the place of average crust-rock, and is subjected to the same average temperature and pressure prevailing in the surrounding crust. But are there ...

... him and raising their voices high in thanks. It was easy, thought Bradley. Really, it was a cinch to be a god. The beasts that were such great dangers to them were mere trifles to him. To him, with a gun loaded with a thousand thermal charges each of which was capable of blasting armor plate. The thing wouldn't even have come close if he himself hadn't been such a timid, cowardly fool. Put Malevski in his place, and the detective would have got the creature as it came out of ...

The "Robinson" Thermal Bath Cabinet is wonderfully simple. A bath in it costs only 2 cents and takes only 15 minutes.

It was built immediately over one of the thermal springs, so that the water flowed from the bowels of the earth directly into the baths. There was accommodation for seventy people, and during the summer and autumn months the place was always full. Not a few also were to be found there during the winter and spring, ...

... to the calorific point of view, in order to estimate the share of energy useful to the organism, we arrive at much the same conclusion. The 46 grs. of nutritive animal elements barely provide 230 thermal units which can be utilised, while the total diet which we are considering brings a power of disposal of nearly 2,350 thermal units. It is, even then, barely 10 per cent. of the total energy. The most convinced flesh eaters, those who buy 400 grs. of meat a ...

... earth's surface live night and day in the midst of aethereal commotion. The medium is never still. The cloud canopy above us may be thick enough to shut out the light of the stars; but this canopy is itself a warm body, which radiates its thermal motion through the aether. The earth also is warm, and sends its heat-pulses incessantly forth. It is the waste of its molecular motion in space that chills the earth upon a clear night; it is the return of thermal motion from the clouds ...
