So, You Think You're an Entrepreneur? 2010-11-18T16:40:00Z He pictured it in the red convection of the womb, growing, thriving, and encroaching on his life. David Bezmozgis: “The Train of Their Departure.” 2010-08-02T04:00:00Z The most important of these was the rapid upward convection in the centers of cyclonic storms whereby abundant heat was carried to high levels where most of it was radiated away into space. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z The field is generated by convection currents in the molten-iron outer-core of the planet, and finding evidence of an even more ancient field would say much about the interior state of the young Earth. Rocks record early magnetic field 2010-05-04T09:19:00Z Generally speaking, the greater part of the heat removal is effected by radiation and convection. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 2 "Ehud" to "Electroscope" 2011-01-29T03:00:23.777Z But if it's thick, we want to understand if convection is getting us material from the ocean to the surface. Jovian vision 2010-03-08T12:52:00Z The part played by a�rial convection is undetermined, but there is no reason to suppose that the infecting material is conveyed any distance by wind or air currents. Encyclopaedia Britannica, 11th Edition, Volume 8, Slice 5 "Dinard" to "Dodsworth" This would arise partly because the storms would be located farther north than now, and partly because of the diminution in temperature due to the increased convection. Climatic Changes Their Nature and Causes 2011-10-28T02:00:24.840Z We may therefore represent the facts by considering the process of electrolysis to be a kind of convection. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" In convection currents electricity is carried from place to place with and on moving material bodies or particles. Encyclopaedia Britannica, 11th Edition, Volume 9, Slice 2 "Ehud" to "Electroscope" 2011-01-29T03:00:23.777Z Inversion is a synonym for vertical convection, and Inclination is used to imply that such clouds consist of sloping lines of falling ice particles. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 5 "Clervaux" to "Cockade" True, the percentage of energy received by convection was small compared to that received by radiation; but it was also wildly variable. Where I Wasn't Going There are two ways in which heat may be applied to the body—by direct radiation, as from the sun or an open fire; and by convection, as through a volume of air. The Turkish Bath Its Design and Construction The escape of heat from a cooling mass is effected by conduction, or by convection, or by both. Essays: Scientific, Political, & Speculative, Vol. I Since heat is so often carried to us by convection,—by warm winds, warm air from the stove, warm ocean currents, etc.,—it seems as if air must be a good conductor of heat. Common Science In these waters a vertical circulation is kept up by convection currents. Encyclopaedia Britannica, 11th Edition, Volume 3, Part 1, Slice 2 "Baconthorpe" to "Bankruptcy" Does the heat reach the hand by convection? Ontario Teachers' Manuals: Nature Study An air thermometer, with a hollow rack-salt bulb, would be unaffected by the heat of the focus: there would be no expansion, and in the open air there is no convection. Fragments of science, V. 1-2 In a solid it is wholly by conduction; in a liquid or gas the chief part is played by convection—by circulating currents which continually transpose the hotter and cooler parts. Essays: Scientific, Political, & Speculative, Vol. I “I suppose you could put this thing in a box, with convection fins, and let it bounce around inside—” “I’m way ahead of you,” I said. The Big Bounce “I know,” cried Vane—“convection: it has to do with water expanding and rising when it is hot and descending when it is cold.” The Weathercock Being the Adventures of a Boy with a Bias Sedimentation from this point of view is a convection of energy. The Birth-Time of the World and Other Scientific Essays The convection current of pure air therefore passed upwards among the inert particles, dragging them after it right and left, but forming between them an impassable black partition. Fragments of science, V. 1-2 When a liquid or a gas moves away from a hot object, carrying heat with it, the process is called convection. General Science From the bottom of the Nile a turbid convection was taking place, as if the river silt had been stirred up, but the fuming current was assuming a dull red tinge. The Yoke A Romance of the Days when the Lord Redeemed the Children of Israel from the Bondage of Egypt Now, suppose I wanted to perform some simple experiment, say, to show what convection is, with water, retort and spirit lamp?” The Weathercock Being the Adventures of a Boy with a Bias Or, if the cold layer is above, and if it is in a sufficient degree colder, there need not be any previous relative motion of the two layers; the inevitable convection currents will suffice. Scientific American Supplement, No. 613, October 1, 1887 These results show how extremely accurate the observations must have been, and that the loss mainly arises from convection and radiation from the boiler. Scientific American Supplement, No. 441, June 14, 1884. The Gulf Stream illustrates the transference of heat by convection. General Science If he gazed through to the bottom he detected a convection in the sand below. The Yoke A Romance of the Days when the Lord Redeemed the Children of Israel from the Bondage of Egypt This convection of negative electricity by the cathode rays seems quite inexplicable on the hypothesis that the rays are ethereal radiations. The New Physics and Its Evolution Hence the conclusion regarding the unity and identity of the current in the case of convection, jointly with the former cases, is not so strange as it might at first appear. Experimental Researches in Electricity, Volume 1 It should be mentioned that the indications of the thermometer during the experiment have been remarkably prompt, the bulb being subjected to the joint influence of radiation and convection. Scientific American Supplement, No. 458, October 11, 1884 In convection, air and water circulate freely, carrying heat with them; in conduction, heat flows from a warm region toward a cold region, but there is no apparent motion of any kind. General Science It took many a night's meditation for the evolution of any fixed idea from the bewildering convection of thought. The Yoke A Romance of the Days when the Lord Redeemed the Children of Israel from the Bondage of Egypt Nothing then remained in order to maintain this hypothesis, except to deny the convection, which, besides, was only established by indirect experiments. The New Physics and Its Evolution Whether convection or carrying discharge will produce the same phenomenon has not been determined, and the few experiments I have as yet had time to make do not enable me to answer in the affirmative. Experimental Researches in Electricity, Volume 1 Air gains and loses heat chiefly by convection, and any gain or loss by conduction may be neglected. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 As will be seen later, modern experiments have confirmed the entire absence of any effect, such as convection would produce, to very high precision. The Project Gutenberg Encyclopedia Volume 1 of 28 For the air resting on the heated surfaces is warmed by convection, rises and gives place to cooler particles, causing a constant heating of its particles by movement. American Woman's Home The bag may be called a "convection shield," slowing convection-cooling due to air currents. The BYU Solar Cooker/Cooler Any convection of that medium could be tested by the change of effective velocity of light, which would be revealed by a prism as was suggested by F. J. D. Arago. The Project Gutenberg Encyclopedia Volume 1 of 28 Frosts generally are preceded by a loss of heat from the lower air strata, due to convection and a horizontal translation of the air. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 True electric current arises solely from convection of the atomic charges or electrons; this current is therefore not restricted as to form in any way. The Project Gutenberg Encyclopedia Volume 1 of 28 The most convenient, economical, and labor-saving mode of employing heat is by convection, as applied in stoves and furnaces. American Woman's Home The convection of a medium thus polarized involves electric disturbance, and therefore must contribute to the true electric current; the determination of this constituent of the current is the most delicate point in the investigation. The Project Gutenberg Encyclopedia Volume 1 of 28 The establishment and convection of a single polar atom constitutes in fact a quasi-magnetization, in addition to the polarization current as above defined, the negative poles completing the current circuits of the positive ones. The Project Gutenberg Encyclopedia Volume 1 of 28 The plant gains heat by convection, radiation and perhaps by conduction of an internal rather than surface character. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 These conditions cannot be consistent with sensible convection of the aether near the earth without involving discontinuity in its motion at some intermediate distance, so that we are thrown back on the previous theory. The Project Gutenberg Encyclopedia Volume 1 of 28 The air is not warmed by the passage of the sun's heat through it, but by convection from the earth, in the same way that it is warmed by the surfaces of stoves. American Woman's Home The Leeds plan embraces the mode of heating both by radiation and convection, very much resembling the open fireplace in operation, and yet securing great economy. American Woman's Home In reference to the warming of rooms and houses already built, there is no doubt that stoves are the most economical mode, as they radiate heat and also warm by convection. American Woman's Home The open fire warms the person, the walls, the floors and the furniture by radiation, and these, together with the fire, warm the air by convection. American Woman's Home |
