Current strength

The Stsndard Depth of Penetration is defined as that depth at which the eddy current strength has dropped to 37% of that at the surface. 

The emission of thermal electrons is subject to statistical fluctuations (lead shot effect). It is influenced by the current strength, the number of electric charges hberated and the frequency of the radiation [55] (see [40] for further details). 

Besides the reversible production of heat at the junctions, there is an evolution of heat all round the circuit due to frictional resistance, this Joule s heat being proportional to the square of the current, and hence not reversed with the latter. There is also a passage of heat by conduction from the hotter to the colder parts. But if the current strength is reduced, the Joule s heat, being proportional to its square, becomes less and less in comparison with the Peltier heat, and with very small currents is negligible. We shall further assume that the reversible thermoelectric phenomena proceed independently of the heat conduction, so that the whole circuit may be treated as a reversible heat... 

The individual polarographic characteristic of the analyzed compound is the potential El/2 at which the current strength equals 50% of its maximum value. The binary solvent benzene-methanol or benzene-ethanol is used. The amount of peroxide is proportional to the maximum strength of the electric current at peroxide concentration in solution lower than... 

A good sample preparation would be one that produces from the original sample a form of carbon that 1) yields a large beam current strength 2) with a minimum of handling and processing 3) with small or no isotopic fractionation 4) from a very small (mg) size sample 5) in minimum time.

Equation where the values of current strength and time of plasma exposure are correlated between each other is the most accurate in describing the dependence. This choice is proved by the least value of exact amount -deviation squares S0CT for the given equation [7],... 

Material response is typically studied using either direct (constant) applied voltage (DC) or alternating applied voltage (AC). The AC response as a function of frequency is characteristic of a material. In the future, such electric spectra may be used as a product identification tool, much like IR spectroscopy. Factors such as current strength, duration of measurement, specimen shape, temperature, and applied pressure affect the electric responses of materials. The response may be delayed because of a number of factors including the interaction between polymer chains, the presence within the chain of specific molecular groupings, and effects related to interactions in the specific atoms themselves. A number of properties, such as relaxation time, power loss, dissipation factor, and power factor are measures of this lag. The movement of dipoles (related to the dipole polarization (P) within a polymer can be divided into two types an orientation polarization (P ) and a dislocation or induced polarization. 

Andfo-Marie Ampere, 1775-1836. French physicist, mathematician, and chemist. Professor at the ficole Polytechnique, Paris. One of the founders of electrodynamics. Inventor of the astatic needle. The practical unit of current strength was named for him. 

A number of factors have been investigated as a response to an imposed (dc) electric field. Current strength, specimen shape, time of measurement, applied pressure, and temperature are typical factors which should be considered. 

Protactinium metal is prepared (1) by reducing the tetrafluoride witli metallic barium at about 1,500 0 (2) by heating the halide, usually the iodide, under a high vacuum and (3) by bombardment of the oxide under high vacuum with 35-keV electrons for hours at a current strength of 0.005 0.010 Amperes. 

Another point is that talipexole and rauwolscine do not only decrease and increase, respectively, the effect of histamine but of course, in addition, decrease and increase NA release per se. One might argue that the alteration in the amount of NA release (rather than the activation or blockade of the a2-adrenoceptor) is the reason why the effect of histamine is decreased and increased, respectively. For clarification of this problem, experiments were done in which the current strength or the duration of the electrical pulses was changed in order to adjust the amount of NA release to the level obtained in brain slices not exposed to the a2-adrenoceptor agonist or antagonist. 

Currently, there is a worldwide wine glut which is the result of several factors, among them bumper crops of 1982 and 1983 coupled with a steady decline in consumption in the major European wine producing countries (Table II) (16). Due to the current strength of the US dollar, American wine is placed in a noncompetitive position in the world market. For example, a Bank of America study (14) showed that in 1979, when the dollar was weak, US wine exports grew almost 120% while imports declined 2%. In 1982, when the dollar was strong, imports grew 6% while exports dropped 11%. 

The term electro-osmosis refers to the passage of a liquid through a membrane during electrolysis. The flow of liquid through this membrane which separates anode from cathode depends upon current strength, the resistance of the liquid, and the thickness and porosity of the membrane.
