Since electrical stimulation of the posterior hypothalamus produces the effects of wakefulness while stimulation of the anterior hypothalamus induces sleep, it may be said that the reactivity of the whole organism is altered by a change in the autonomic reactivity of the hypothalamus.

Since the electrical conductivity is low, gases are dielectrics or insulators.

Since electrical energy cannot easily be stored in quantities large enough to meet demands on a national scale, at all times exactly as much must be produced as is required.

Since that, bilateral trade between Malaysia and Oman stood at nearly RM500 million during January – October 2010, with Malaysia's main exports to Oman being edible oil, machinery, appliances and parts, wood products, electrical and electronic products.

Since batteries produce direct current ( DC ) rather than alternating current ( AC ), induction coils relied upon vibrating electrical contacts that regularly interrupted the current in the primary to create the flux changes necessary for induction.

Since the plasma is an electrical conductor, it is possible to heat the plasma by inducing a current through it ; in fact, the induced current that heats the plasma usually provides most of the poloidal field.

Since AM assumes short term changes in the amplitude to be information, any electrical impulse will be picked up and demodulated along with the desired carrier.

Since the ground is not a perfect electrical conductor, ground waves are attenuated as they follow the earth ’ s surface.

Since a Van de Graaff generator can supply the same small current at almost any level of electrical potential, it is an example of a nearly ideal current source.

Since the electrical conductivity is extremely low, gases are dielectrics or insulators.

Since they have far fewer electrical connections to fail, they are far more reliable than space-division switches, and are therefore the preferred switches for the outer ( input and output ) layers of modern telephone switches.

Since the power dissipated by a resistor is the amount of energy used ( electrical work applied ) per unit time, the total energy consumed and dissipated in time t is:

Since the voltage that is induced in the coil is proportional to the rate of change ( derivative ) of current in the straight conductor, the output of the Rogowski coil is usually connected to an electrical ( or electronic ) integrator circuit to provide an output signal that is proportional to the current.

Since electrical conductance is reciprocal to resistance, the expression for total conductance of a parallel circuit of resistors reads:

Since these fieldline properties seemed to be exhibited down to the event horizon, and general relativity insisted that no dynamic exterior interactions could extend through the horizon, it was considered convenient to invent a surface at the horizon that these electrical properties could be said to belong to.

Since electric vehicles use whatever electricity is delivered by their electrical utility / grid operator, electric vehicles can be made more or less efficient, polluting and expensive to run, by modifying the electrical generating stations.

Since the advent of new technologies such as electrical discharge machining, electrochemical machining, electron beam machining, photochemical machining, and ultrasonic machining, the retronym " conventional machining " can be used to differentiate those classic technologies from the newer ones.

Since the accessory pathway does not have the impulse slowing properties of the AV node, the electrical impulse first activates the ventricles via the accessory pathway, and immediately afterwards via the AV node.

Since US electrical code requires bonding of ground to neutral at the electrical service entrance, the resulting surge ultimately flows into ground at that connection, but by first dumping into neutral, nearby ground contamination is avoided.

Since Karloff's portrayal, the creature almost always appears as a towering, gruesome figure, often with a flat square-shaped head and bolts to serve as electrical connectors or grotesque electrodes on his neck.

Since the design of such high-end chips nominally takes about five years to complete, to stay competitive a company has to fund at least two of these large design teams to release products at the rate of 2. 5 years per product generation.

Since the cancellation of the XM8 program, and into 2008, the LSAT rifle program has been pursued for the next generation of U. S. small arms.

Since the launch of the third generation MX-5, Mazda consolidated worldwide marketing using the MX-5 name, though enthusiasts in the US still refer to it as Miata, a name that means " reward " in Old High German, and the vehicle in 2012 was still marketed by Mazda in the US as the MX-5 Miata.

Since this angle varies depending on system loading and generation, it is undesirable for the angle to approach 90 degrees.

Since Joseph had no male children, and because Louis-Napoléon's own elder brother had died in 1831, the death of the Duke of Reichstadt in 1832 made Louis-Napoléon the Bonaparte heir in the next generation.

Since he first came to prominence in the mid-1960s, critics have cited Campbell as one of the leading writers in his field: T. E. D. Klein has written that " Campbell reigns supreme in the field today ", while S. T. Joshi stated, " future generations will regard him as the leading horror writer of our generation, every bit the equal of Lovecraft or Blackwood.

Since May 2011 in Tychy will start production of the first model of this mark-all-new Lancia Ypsilon 3rd generation.

Since 1983, Reform Judaism in the United States of America officially adopted a bilineal policy: one is a Jew if either of one's parents is Jewish, provided that either ( a ) one is raised as a Jew, by Reform standards, or ( b ) one engages in an appropriate act of public identification, formalizing a practice that had been common in Reform synagogues for at least a generation.

Since such a ship might take thousands of years to reach even nearby stars, the original occupants of a generation ship would grow old and die, leaving their descendants to continue travelling.

Since 1998 these letters have been recognised as representing the sixth and seventh lines of the Fourth Eclogue of Virgil, which reads Redeunt Saturnia Regna, Iam Nova Progenies Caelo Demittitur Alto, meaning ' The Golden Ages are back, now a new generation is let down from Heaven above '.

Since her death, Dalida has become a cult figure to a new generation of fans.

Since few were alive at older ages and their contribution to the next generation was therefore small relative to the large cohorts of younger age groups, the force of selection against such late-acting deleterious mutations was correspondingly small.

Since 2007 a third generation muga with synthetic grass allows all year play.

Since then, the company has sometimes used 1982 as the starting birth year for this generation.

Since this discovery occurred in 1999, ES cells have become a key tool in the generation of specific chimeric mice.

He commented on his website: " Since Spider-Man 1 and 2, I seem to have a whole new generation of fans.

( Since generation time scales with body mass < sup > 0. 259 </ sup >, increasing generation times with increasing size cause the log mass vs. time plot to curve downward from a linear fit.

Since then, a step-by-step process of industry reform has led to the separation of the monopoly elements from the contestable elements to create competitive markets in energy generation and electricity retailing, while imposing regulation on the natural monopolies of transmission and distribution.

Since, however, his book was too philosophical to be popular, the author's theories were practically unnoticed for a generation, and the new ideas are now associated especially with the names of Abraham Kuenen and Julius Wellhausen.

Since April 2010, a facelifted version of the second generation Elise has been available.

Since the Model 39 debuted, Smith & Wesson has continuously developed this design into its third generation pistols now on the market.

Since the introduction of the MiG-15 and North American F-86 which demonstrated a decisive superiority over the slower first generation of straight-wing jet fighters during the Korean War, swept wings have become almost universal on all but the slowest jets ( such as the A-10 ).

Since the 1920s the water of the Isar has been used for the generation of electricity.

Since then, Quadrics have brought out a second generation of 10 GigE switches, starting with a compact 1U switch with 24 ports, which comes in two variants, TG201-CA, 24 ports CX4, and TG201-XA, 24 ports in total, 12 XSP and 12 CX4.
