It simplifies the theory, and gives a possible relation between the constants, but it does not appear to remove the complication above referred to, which seems to be inseparable from any conduction theory. is due to the conduction of heat in the metal, which is contrary to Thomson's theor y. Local anesthetic agents may be administered intradermally or subcutaneously to block impulse conduction in local nerve fibers. A water-soluble gel is placed on the underside of the transducer to permit the conduction of fetal heart sounds. The disk is cooled primarily by conduction across the gap region, which can be filled with high-thermal-conductivity gases like helium. Digoxin also acts indirectly by increasing parasympathetic activity via the vagus nerve, further slowing atrioventricular node conduction. This conclusion is confirmed by the results of the direct visual determination of ionic velocities (see Conduction, Electric, § Ii. Cardiovascular system Tachycardia, hypotension, at times hypertension, conduction disturbance with widening of QRS complex; syncope in association with cardiac arrest. conduction disturbances increase with age. That, however, complete conduction should arrive with alternations only ten times slower than light was an unexpected and remarkable fact, which verifies the presumption that the process of conduction is one in which the dynamic activities of the molecules do not come into play. abnormalityction conduction abnormalities were present in 91% . His most important work was concerned with the conduction of heat and with spectroscopy. Warm air rises by the process of convection. Conduction can occur in liquid, gaseous or solid objects. The definition of conduction is the movement of something such as heat or electricity through a medium or passage. In starting the furnace, the bottom is prepared by ramming it with charcoal-powder that has been soaked in milk of lime and dried, so that each particle is coated with a film of lime, which serves to reduce the loss of current by conduction through the lining when the furnace becomes hot. Traducir conduction de Inglés a español. (Id., 27, p. Conduction In A Sentence Definition of Conduction (physics) The conveying of heat or electricity through material. Thomson, Recent Researches in Electricity and Magnetism (Oxford, 1893); id., Conduction of Electricity through Gases (Cambridge, 1903); id., Electricity and Matter (London, 1904); O.

Although the cell body or perikaryon of the neuron, with its contained nucleus, is essential for the maintenance of the life of the cell branches, it has become recognized that the actual process and function of "conduction" in many neurons can, and does, go on without the cell body being directly concerned in the conduction. Necessary cookies are absolutely essential for the website to function properly. Taking conduction into account in the application of the second law of thermodynamics, he proposes to substitute the inequality, Td/dET - P, Others have considered conduction in a metal to be analogous to electrolytic conduction, and the observed effects to be due to " migration of the ions.". He developed a great research laboratory of experimental physics, attracting numerous workers from many countries and colonies; advances were made in the investigation of the conduction of electricity through gases, in the determination of the charge and mass of the electron and in the development of analysis by means of positive rays. It is, however, probable that conduction is to some extent a factor in the process. ‘Electrical conduction is the net motion of electric charge, and it cannot take place without the motion of matter on some scale.’ ‘So far, electron conduction has only been found in a few, high electron-affinity organic semiconductors, until now.’ How to use conduction in a sentence. Conduction: This occurs when heat moves through the walls. 7. : A thundercloud, with a distinctive upper anvil shape, results from air which is moist and unstable rising by convection. Wood thus altered is known as heart-wood, or duramen, as distinguished from the young sap-wood, or alburnum, which, forming a cylinder next the cambium, remains alive and carries on the active functions of the xylem, particularly the conduction of water. Heat energy is transported in the Sun by conduction and. heat transfer by lattice vibrations. 5. The difference between bone conduction loss and neurosensory hearing loss is called the air-bone gap. A group of bodies may, however, be yet discovered between alloys and electrolytes in which evidence may be found of some gradual change from wholly metallic to electrolytic conduction. | The act of leading or guiding. It is difficult to see how this complication can be avoided, unless the first postulate is abandoned, and the heat-flow due to conduction is assumed to be independent of the thermoelectric phenomena. Any cookies that may not be particularly necessary for the website to function and is used specifically to collect user personal data via analytics, ads, other embedded contents are termed as non-necessary cookies. In convection, hot currents flow upwards. If the battery leaks inside and dries, you'll have to clean out the grey gunk to be assured of clean conduction. He held his prefecture for fourteen years; and it was during this period that he carried on his elaborate and fruitful investigations on the conduction of heat. The top and bottom rows of the xylem rays are often developed as irregularly-thickened radially-elongated tracheids which serve for the radial conduction of water, and communicate with the ordinary tracheids of the secondary xylem by large bordered pits. Who is a bone conduction hearing aid suitable for? The presence of these threads between all the cells of tfie plant shows that the plant body must be regarded as a connected whole; the threads themselves probably play an important part in the growth of the cell-wall, the conduction of food and water, the process of secretion and the transmission of impulses. Kilometers of super conductive piping runs into the silicon dunes as anthills do. We also use third-party cookies that help us analyze and understand how you use this website. Given a certain allowable heat transmission, the principal points to be considered in connexion with insulation are, first cost, durability, weight and space occupied, the two last named being specially important factors on board ship. The surface of the calorimeter and the enclosure should be permanently blackened so as to increase the loss of heat by radiation as much as possible, as compared with the losses by convection and conduction, which are less regular. The increasing development of the wood as the tree grows older is largely due to the demands for the conduction of water and mineral matters dissolved in it, which are made by the increased number of leaves which from year to year it bears, and which must each be put into communication with the central mass by the formation of new vascular bundles. P. Granville put into practice between Alum Bay in the Isle of Wight and the Needles lighthouse a method which depends upon conduction through sea water. A continuous flow calorimeter has been used by the writer for measuring quantities of heat conveyed by conduction (see Conduction Of Heat), and also for determining the variation of the specific heat of water. Our views of the nature of the ions of electrolytes have been extended by the application of the ideas of the relations between matter and electricity obtained by the study of electric conduction through gases. Though it is raining, they swam in the pool. Heat transfer occurs when there is molecular agitation and energy flow from an object at a higher temperature. Michael has very much money. - Measurements of thermal conductivity present peculiar difficulties on account of the variety of quantities to be observed, the slowness of the process of conduction, the impossibility of isolating a quantity of heat, and the difficulty of exactly realizing the theoretical conditions of the problem. thermal conductivity in a sentence - Use "thermal conductivity" in a sentence 1. www.use-in-a-sentence.com English words and Examples of Usage Example Sentences for "conduction "The natural processes result, on the one hand, in the preparation of fit and proper nutriment out of the materials of the digested food, for the growth and support of the several tissues and functions; and, on the other hand, in the gradual change and conduction out of the … See more. 4.

However, the term also covers nerve conduction studies - testing the electrical function of nerve conduction studies - testing the electrical function of nerves in the limbs. How to use conduction in a sentence. Conduction definition, the act of conducting, as of water through a pipe. Here we have an instance of the conduction of heat. Beneath these layers are masses of salter water, through which a thermal wave of small amplitude is slowly propagated to the bottom by conduction. Fourier (I822) in connection with the conduction of heat. That is to say, instead of using Boyle's law, which supposes that the pressure changes so exceedingly slowly that conduction keeps the temperature constant, we must use the adiabatic relation p = kpy, whence d p /d p = y k p Y 1= yp/p, and U = (yp/p) [Laplace's formula]. If this doesn't sway you, you'll reap the benefits of great heat conduction and a low price. Conduction: The body absorbs cold when exposed to cold surfaces, such as when you sit on the cold ground or hold cold objects. In the nerve conduction study, small electrodes are placed on the skin over the muscles to be examined. The electromotive force of the coil is, however, great enough to create in these air gaps displacement currents which are of magnitude sufficient to be equivalent to the conduction current required to actuate a telephone. Hence, concentration driven con Electrical conduction is the transfer of electrically charged particles through a medium, such as electricity traveling through the power lines in your house. Here we have an instance of the conduction of heat. Measurements of such order are usually made by diffraction techniques, which detect the ionic cores and the spins of the conduction electrons. These are effective in reducing phonon conduction, i.e. The rate of transmission of heat is Q/AT, and the temperature gradient, supposed uniform, is (B' - B') /x, so that the law of conduction leads at once to the equation Q/AT = k (e' - 0"(/x = kdO/dx. Definition of Conduction the process by which sound waves travel through another material Examples of Conduction in a sentence The conduction of sound through the air is what allows us to hear all of the noise around us, since we wouldn’t hear anything if the sound didn’t travel to our ears from its source. For conduction to take place between two objects, they must be touching each other. Conduction definition: Conduction is the process by which heat or electricity passes through or along something. In this manner Trowbridge showed that signalling might be carried on over considerable distances by electric conduction through the earth or water between places not metallically connected. This category only includes cookies that ensures basic functionalities and security features of the website. eightfold space of uppermost valence and lowest conduction bands at the center of the Brillouin zone and its vicinity. Next To The Radiation Loss, The Most Uncertain Correction Was That For Conduction Of Heat Along The 4 In. He also repeated the suggestion which Lindsay had already made that it might be possible to signal in this manner by conduction currents through the Atlantic Ocean from the United States to Europe. : In spring when the air temperature outside the bin is higher than the grain temperature, a reverse convection current … Examples of Conductive in a sentence The conductive wiring may feel warm to the touch because of the electricity it’s carrying. ‘Electrical conduction is the net motion of electric charge, and it cannot take place without the motion of matter on some scale.’ ‘So far, electron conduction has only been found in a few, high electron-affinity organic semiconductors, until now.’ and growth, reception and conduction of stimuli, heredity, variation, sex and reproduction. Thomson has shown (see CONDUCTION, ELECTRIC, § III.) (noun) Designating or of an oven, grill, etc. If we eliminate the reverse electromotive forces of polarization at the two electrodes, the conduction of electricity through electrolytes is found to conform to Ohm's law; that is, once the polarization is overcome, the current is proportional to the electromotive force applied to the bulk of the liquid. Heartbeat abnormalities such as tachycardia (rapid heart rate) and heart block (impaired conduction of the heart's cardiac impulses) are common occurrences. 3), which practically eliminates conduction and convection. Consider breakability, how likely it is to scratch while you cook, reactivity, and heat conduction. Up to 1895 or 1896 the suggestions for wireless telegraphy which had been publicly announced or tried can thus be classified under three or four divisions, based respectively upon electrical conduction through the soil or sea, magnetic induction through space, combinations of the two foregoing, and lastly, electrostatic induction.
