Since several elements are gases at commonly encountered temperatures, their densities are usually stated for their gaseous forms ; when liquefied or solidified, the gaseous elements have densities similar to those of the other elements.

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

Since part of this re-radiation is back towards the surface and the lower atmosphere, it results in an elevation of the average surface temperature above what it would be in the absence of the gases.

Since the CFCs themselves are equally powerful greenhouse gases, the mere substitution of HFCs for CFCs does not significantly increase the rate of anthropogenic global warming, but over time a steady increase in their use could increase the danger that human activity will change the climate.

Since interactions between molecules play almost no role, dilute gases form rather trivial solutions.

Since most of the atmosphere's quantity of such triatomic gases is contained within the troposphere, this portion of the atmosphere is readily heated by the earth's radiation.

Since the dielectric strength of gases varies depending on the shape and configuration of the electrodes, it is usually measured as a fraction of the dielectric strength of Nitrogen gas.

Since the molar volume of gases is very roughly 1000 times that of solids and liquids, this results in a factor of about 1000 loss in volumetric heat capacity for gases, as compared with liquids and solids.

Since the land's surface is warm, the gases expand and an area of low pressure develops.

Since the Otto cycle is an isentropic process the isentropic equations of ideal gases and the constant pressure / volume relations can be used to yield Equations 3 & 4.

Since the valves control the flow of the air / fuel mixture intake and exhaust gases, they must be opened and closed at the appropriate time during the stroke of the piston.

Since the EGR system recirculates a portion of exhaust gases, over time the valve can become clogged with carbon deposits that prevent it from operating properly.

Since there are living cells within the cambium layers that need to exchange gases during metabolism, these lenticels, because they have numerous intercellular spaces, allow gaseous exchange with the outside atmosphere.

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

Since venting hot gases to the rear can be dangerous in confined spaces, some recoilless guns such as the Armbrust and MATADOR use a combination of a countershot, smoothbore barrel and pistons to avoid both recoil and back blast.

Since its construction, constant emissions of heat and caustic gases have transformed much of the rock into clays ( mostly kaolinite ), iron oxides, sulfur-rich compounds and quartz.

Since a strong seal is needed to trap propellant gases behind the projectile, and keep the projectile centered in the barrel, something is needed to fill the undesirable but necessary gap between projectile and barrel, a space referred to as the windage, and this is the role of the sabot.

* Since the temperature difference between the hot gases and the fluid to be heated ( steam or water ) is low, and with the heat transmission coefficient being low as well, the evaporator and economizer are designed with plate fin heat exchangers.

Since a metal-halide lamp contains gases at a significant high pressure, failure of the arc tube is inevitably a violent event.

* Since hydrogen is likely to be made from combustion of fossil fuels, it produces less CO < sub > 2 </ sub > and other greenhouse gases to burn the fossil fuel directly.

Since a natural gas stream contains a mix of various hydrocarbon gases of different specific gravities, mole percentages must be determined via a gas sample analysis.

Since the homosexuals widely use marijuana, they do not have to be initiated.

Since the slogans have little application to reality and are sanctimonious to boot, the applause is faint even in areas of the world where we should expect to find the greatest affection for free government.

Since Rhode Island at that time did not have such sanction, his opinion was not popular.

Since the great flood of these dystopias has appeared only in the last twelve years, it seems fairly reasonable to assume that the chief impetus was the 1949 publication of Nineteen Eighty-Four, an assumption which is supported by the frequent echoes of such details as Room 101, along with education by conditioning from Brave New World, a book to which science-fiction writers may well have returned with new interest after reading the more powerful Orwell dystopia.

Since 1957, more and more trans-Atlantic passengers have been crossing by air.

Since two of these could be trustees of the college, actually it would be necessary to have the consent of only one elected official to impose a levy of millions of dollars of tax revenue.

Since appeals to morality, to humanity, and to sanity have had such small effect, perhaps our last recourse is the deterrent example.

`` Since the war I have seen the way the Germans have behaved and I think, Holy Mother, we have behaved like this for hundreds of years.

Since that time the demands of the citizens for new and expanded services have placed financial burdens on the state which could not have been foreseen in earlier years.

Since faculty see themselves as self-employed professionals rather than as employees, enthusiasm in a common enterprise is proportionate to the sense of ownership they have in it by virtue of sharing in the decisions that govern its course.

Since the concept of high fidelity became important some dozen years ago, the claims of technical improvements have multiplied tenfold.

Since SAAMI's conception in 1926, and more specifically since the adoption of the Shooting Development Program in 1954, millions of dollars and promotional man-hours have gone into the development of more places to shoot for more youths and adults.

Says NRLDA's James Wright: `` Since 1958 carriers that move material from the yard to the job site have undergone more radical changes than any of the dealer's other equipment ''.

Since practical washing procedures are both lengthy and expensive, a number of laboratory tests have been developed for the numerical evaluation of detergents.

Since there is a continual loss of micrometeoritic material in space because of the radiation effects, there must be a continual replenishment: otherwise, micrometeorites would have disappeared from interplanetary space.

Since Af and P divides Af for Af, we have Af.

A final class of exceptional lines is identifiable from the following considerations: Since no two generators of Af can intersect, it follows that their image curves can have no free intersections.

Since they are all either rented or borrowed, the requested dates for their use have to be far in advance.

Since the writer had not noticed this characteristic in married students scattered throughout the various sections previous to this experiment, nor, as a matter of fact, in those who were continuing in `` single sections '', he can only conclude that there must have been something `` contagious '' within the specific group which caused this to occur.

Since the details of the elections were settled the change of government had no direct effect on the technical aspects of the elections, and may have been more important as an indication of royal displeasure with the U.N.F.P.

Since 1917 some thirteen supplementary and related acts have extended this Federal program.

Since this type of item was not in the statute when section 381 was enacted in 1954, one cannot say with certainty what effect the enactment of that section should have.
