Fragments of science, V. 1-2 They act sometimes separately, and sometimes they interact in conduction with each other, producing their various effects. Evolution in Modern Thought Here an increase in the potential difference produces a much greater percentage increase than in conduction through metals, where the current is proportional to the potential difference. Encyclopaedia Britannica, 11th Edition, Volume 6, Slice 8 "Conduction, Electric" But there may be a likelihood that the power of conduction possessed by a nerve is not constant but capable of change. Sir Jagadis Chunder Bose His Life and Speeches The function of nerve fibres is simply conduction, and the nature of the impressions they convey is entirely determined by the nature of their distal and proximal terminations. Text Book of Biology, Part 1: Vertebrata The local character of the signs seems, however, to point to causation by molecular disturbance, resulting from the conduction of forcible mechanical vibration to the brain tissue rather than to upset in the intra-cranial pressure. Surgical Experiences in South Africa, 1899-1900 Being Mainly a Clinical Study of the Nature and Effects of Injuries Produced by Bullets of Small Calibre I am now convinced that the è is an error of the writer or the copyist and should be simply the conduction e. Lucretia Borgia According to Original Documents and Correspondence of Her Day True, we have things like NaCl solutions in ordinary H2O which will carry electricity, but here it's ionic conduction. The Black Star Passes "Indeed, then, you're right, ma'am," put in nurse, who happened to be in the room, adding, with a pointed glance at me, "I wonder what the dear lady would 'a' said to this day's conductions!" We Ten Or, The Story of the Roses In thalloid forms a thinner marginal expansion or a definite wing increasing the surface exposed to the light can be distinguished from a thicker midrib serving for storage and conduction. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3 "Brescia" to "Bulgaria" The syllables belonging to a word are often separated by pauses like the words themselves—a sort of dysphasia-of-conduction on account of the more difficult and prolonged conduction of the motor-impulse. The Mind of the Child, Part II The Development of the Intellect, International Education Series Edited By William T. Harris, Volume IX. While in some forms of animal tissue irritation spreads, at a very slow rate, only to points in close neighbourhood, in other forms, as for example in nerves, conduction is very rapid and reaches far. Response in the Living and Non-Living No substance capable of carrying electricity by metallic conduction is transparent. The Black Star Passes By the conduction and radiation of heat from its surface as from a stove. Physiology and Hygiene for Secondary Schools The elaters serve as lines of conduction of plastic material to the developing spores, and later usually assist in their dispersal. Encyclopaedia Britannica, 11th Edition, Volume 4, Part 3 "Brescia" to "Bulgaria" How is it as to the existence and practicability of the nervous conduction, and the genesis of the centers? The Mind of the Child, Part II The Development of the Intellect, International Education Series Edited By William T. Harris, Volume IX. The greater output of light is compensated by losses by conduction of heat through the gas. Artificial Light Its Influence upon Civilization Now we know that there is no substance which is transparent to light, that will carry electricity by metallic conduction. The Black Star Passes After being induced the change results by supposing the conduction of electricity either from the upper or from the lower side, according to greater or smaller speed of the air in the height. Scientific American Supplement, No. 633, February 18, 1888 Hence the self-induction of a strand, coil or conductor of the same section varies with the rapidity of current changes, owing to the conduction being uneven. Scientific American Supplement, No. 711, August 17, 1889 This carrying of the heat from particle to particle through the length of the rod is called heating by conduction. The First Book of Farming The knowledge gained in these investigations indicated that a thicker filament lost a relatively less percentage of energy by conduction than a thin one for equal amounts of emitted light. Artificial Light Its Influence upon Civilization But again, glass is not a solid, but a viscous liquid, and it is again carried by ionic conduction. The Black Star Passes The combustion, moreover, is never perfect; and some heat is lost by conduction and radiation. Scientific American Supplement, No. 508, September 26, 1885 Heat excited, concentrated into a certain point of a solid body, communicates itself by way of conduction, first to the particles nearest the heated point, then gradually to all the regions of the body. Biographies of Distinguished Scientific Men Because its darker color helped it to absorb heat more rapidly than the sand, and, as the particles were smaller and more compact, heat was carried into it more rapidly by conduction. The First Book of Farming Other methods involve conduction of heat from the hot air or other hot applications. Artificial Light Its Influence upon Civilization That the molecules of those substances, being frictionless bodies in a frictionless medium, and their motion not being dissipated by conduction or radiation, continue incessantly in motion until some cause arises to prevent them. Scientific American Supplement, No. 443, June 28, 1884 It is not a matter of the conduction of heat from point to point in the ice. The Birth-Time of the World and Other Scientific Essays When heat flows in this way from a warm part of a body to a colder part, the process is called conduction. General Science The mulch will also check the conduction of heat from the lower soil to the surface and therefore check loss of heat by radiation from the surface. The First Book of Farming Giese was a forerunner, but his ideas could not triumph so long as there were no means of observing conduction in simple circumstances. The New Physics and Its Evolution See Brush, electric —— condition of particles of matter —— conduction, . Experimental Researches in Electricity, Volume 1 This region will, however, again warm up by conduction of heat from the surrounding ice, or by the circulation of water from the suxface.

General Science Placing the square between the prisms, and heating the wire, the heat passes by conduction to the glass, through which it spreads from the centre outwards. Six Lectures on Light Delivered In The United States In 1872-1873 In two memoirs published in 1882 and 1889, he plainly arrives at the conception that conduction in gases is not due to their molecules, but to certain fragments of them or to ions. The New Physics and Its Evolution Though assumed to be essentially different, yet neither Cavendish nor Poisson attempt to explain by, or even state in, their theories, what the essential difference between insulation and conduction is. Experimental Researches in Electricity, Volume 1 His most important work was concerned with the conduction of heat and with spectroscopy. Encyclopaedia Britannica, 11th Edition, Volume 2, Part 1, Slice 1 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.

Experimental Researches in Electricity, Volume 1 Heat is lost to the body through the faeces and urine, respiration, conduction and radiation from the skin, and by evaporation of perspiration. Encyclopaedia Britannica, 11th Edition, Volume 2, Part 1, Slice 1 In a transparent dielectric the conduction must be either electrolytic or disruptive, otherwise light vibrations would be damped. Scientific American Supplement, No. 795, March 28, 1891 In the former case, the bodies are in good heat-communication with the ground, whereas in the latter little or no heat is received by conduction from the earth. Scientific American Supplement, No. 530, February 27, 1886 Nothing in his past life, nothing in his conductions, nothing in his expensiture, nothing to find fault with. Light With an electric current of, or under this intensity, it is probable that increasing the number of interposed platina plates would not involve an increased difficulty of conduction. Experimental Researches in Electricity, Volume 1 This is true both of the nervous system as a whole and of any particular conduction unit. How to Teach But conduction and induction combined would not carry messages to a distance that would enable extensive communication. Masters of Space Morse, Thompson, Bell, Marconi, Carty For the conduction of these researches the sanitary superintendent is allowed a competent chemical staff. Hygeia, a City of Health 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 If the water is altered only in that small degree which consists in its having the solid instead of the fluid state, the conduction is stopped, and the decomposition is stopped with it. Experimental Researches in Electricity, Volume 1 Currents originally passing with difficulty over a certain conduction unit later pass with greater and greater ease. How to Teach Preece finally decided that a combination of conduction and induction was the best means of wireless communication.

The Dawn of Amateur Radio in the U.K. and Greece: a personal view 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 On the other hand, the relation between the conduction of the electricity and the decomposition of the water is so close, that one cannot take place without the other. Experimental Researches in Electricity, Volume 1 The air-tubes are placed so as to intercept the hot gases as completely as possible; and also, of course, obtain heat by conduction from the sides of the annular body. Scientific American Supplement, No. 362, December 9, 1882 This is an important point, as many physicists speak and write of the phenomenon as one of conduction. Scientific American Supplement, No. 275, April 9, 1881 Heat may be lost from a flame in three several ways: by direct radiation and conduction into the surrounding air, among the products of combustion, and by conduction into the body of the burner. Acetylene, the Principles of Its Generation and Use A Practical Handbook on the Production, Purification, and Subsequent Treatment of Acetylene for the Development of Light, Heat, and Power This small gap is a place of bad conduction and of the piling up of atoms, producing heat, burning, light. Steam, Steel and Electricity Upon thawing parts of this thin film, at both metals, conduction occurred. Experimental Researches in Electricity, Volume 1 Plug connection so heat insulated as to prevent conduction of heat, and overheating of cord at connections. The Consumer Viewpoint This is because the glass being heated no longer condenses the vapor on its surface, and there is no superficial conduction, as in the previous case. Scientific American Supplement, No. 275, April 9, 1881 The more blood passes through the skin, the greater will be the loss of heat by conduction, radiation, and evaporation. A Practical Physiology Removal of the thyroid produces a degeneration of nerve cells and their processes, and associative memory becomes difficult or impossible because conduction from cell to cell is interfered with. The Glands Regulating Personality I think it expedient, next in the course of these experimental researches, to describe some effects due to conduction, obtained with such bodies as glass, lac, sulphur, &c., which had not been anticipated. Experimental Researches in Electricity, Volume 1 The external covering controlled the influx of cold from the penetrating winds, and, on the other hand, the conduction of the sun's warmth in summer. The Home of the Blizzard Being the Story of the Australasian Antarctic Expedition, 1911-1914 But about the details of that conduction I need know nothing. The Nature of Goodness When a man feels too warm and throws off his coat, he removes one of the badly conducting layers of air, and increases the heat loss by radiation and conduction. A Practical Physiology If sufficient thyroid is fed in excess, brain conduction may be so facilitated that epilepsy may result upon slight irritation. The Glands Regulating Personality I hope, therefore, I may be excused the attempt to look at the highest cases of conduction as analogous to, or even the same in kind with, those of induction and insulation. Experimental Researches in Electricity, Volume 1 The roots of this tree do not penetrate deeply into the earth, but are spread out near the surface, and of course do not carry off the waters of the swamp by perpendicular conduction. The Earth as Modified by Human Action He lets it cover any process of conduction from a present idea to a future terminus, provided only it run prosperously. Pragmatism The blood, in its swiftly flowing current, carries warmth from the tissues where heat is being rapidly generated, to the tissues or organs in which it is being lost by radiation, conduction, or evaporation. A Practical Physiology The rate of electrolytic conduction is, according to Wiedemann's theory, influenced by the same cause; and the conduction of heat in fluids depends probably on the same kind of action. Five of Maxwell's Papers Thus, that which is called simply conduction involves no chemical action, and apparently no displacement of the particles concerned. Experimental Researches in Electricity, Volume 1 Supposing the conduction to be insufficient for a given purpose; a purpose which shall require perfect conduction? Mont-Saint-Michel and Chartres His next important discovery was that colors had nothing to do with the conduction of electricity. A History of Science — Volume 2 With regard to the conduction of sound—it is to be noted that sound is carried astonishingly far by means of compact bodies. Criminal Psychology; a manual for judges, practitioners, and students They are charged like the particles of the insulator, but they discharge with greater ease and rapidity; and this rapidity of molecular discharge is what we call conduction. Faraday as a Discoverer In ice or water we have a better conductor than spermaceti, and the phenomena of induction and insulation therefore rapidly disappear, because conduction quickly follows upon the assumption of the inductive state. Experimental Researches in Electricity, Volume 1 Among these infinite lines, a certain group ran to the human race, and, as long as the conduction was perfect, each man acted mechanically. Mont-Saint-Michel and Chartres That these mineral acids should confer facility of conduction and decomposition on water, is no proof that they are competent to favour and suffer these actions in themselves. Experimental Researches in Electricity, Volume 1 The question then arises, what is this limiting condition which separates, as it were, conduction and insulation from each other? Experimental Researches in Electricity, Volume 1 Researches on frictional electricity: induction: conduction: specific inductive capacity: theory of contiguous particles. Faraday as a Discoverer Especially too, as we have not in nature the case of perfection either at one extremity or the other, either of insulation or conduction. Experimental Researches in Electricity, Volume 1 Thus the three very different modes of discharge, namely, conduction, electrolyzation, and disruptive discharge, agree in producing the important transverse phenomenon of magnetism. Experimental Researches in Electricity, Volume 1 With regard to airs, one is almost led to expect a permanent difference of force; but in all other bodies, time seems to be quite sufficient to ensure, ultimately, complete conduction. Experimental Researches in Electricity, Volume 1 I venture to give the following summary of the conditions of electric conduction in bodies, not however without fearing that I may have omitted some important points79. Experimental Researches in Electricity, Volume 1 This polar arrangement must precede decomposition, and decomposition is an accompaniment of conduction. Faraday as a Discoverer The specific differences of bodies as to conducting power only serves to strengthen the general argument, that conduction, like insulation, is a result of induction, and is an action of contiguous particles. Experimental Researches in Electricity, Volume 1 There is no strict electrical distinction of conduction which can, as yet, be drawn between bodies supposed to be elementary, and those known to be compounds. Experimental Researches in Electricity, Volume 1 But on examination there were strong reasons for believing that water was present, and that the decomposition and conduction depended upon it. Experimental Researches in Electricity, Volume 1 Is then the act of decomposition essential to the act of conduction in these bodies? Faraday as a Discoverer Conduction then is always preceded by atomic induction; and when, through some quality of the body which Faraday does not define, the atomic discharge is rendered slow and difficult, conduction passes into insulation. Faraday as a Discoverer Here induction appears to be a necessary preliminary to conduction. Experimental Researches in Electricity, Volume 1 |
