Since the absorption of radio waves in rocklike material varies with wave length, it should be possible to sample the temperature variation at different depths beneath the surface and possibly detect changes in the structure or composition of the lunar surface material.

Since Fogg's was a one-man, one-plane flying service, this meant that he would have to do both trips, flying alone 600 miles a day, under sub-freezing temperature conditions.

Since amphibians are cold-blooded, they must find ways to keep their blood at a constant temperature to maintain homeostasis.

Since temperature is thermodynamically conjugate to entropy, the isothermal process is conjugate to the adiabatic process for reversible transformations.

Since at constant temperature, the entropy is proportional to the volume, the entropy increases in this case, therefore this process is irreversible.

Since the speed of sound varies with temperature, and is virtually stable with pressure change, sonic anemometers are also used as thermometers.

Since many scientific applications require incubation at temperatures close to human body temperature ( 37 ° C ), agar is more appropriate than other solidifying agents that melt at this temperature, such as gelatin.

Since the entropy increases with temperature, many endothermic reactions preferably take place at high temperatures.

Since blunt-ended DNA fragments have no cohesive ends to anneal, the melting temperature is not a factor to consider within the normal temperature range of the ligation reaction.

Since these properties are often used as reference values it is very common to quote them for a standardized set of environmental parameters, or standard conditions, which is typically a temperature of and a pressure of either or.

Since the kinetic energy of a molecule is proportional to its temperature, evaporation proceeds more quickly at higher temperatures.

The event temporarily warmed air temperature by 1. 5 ° C, compared to the usual increase of 0. 25 ° C associated with El Niño events .< ref name =" Trenberth "> Since then, mass coral bleaching has become common worldwide, with all regions having suffered " severe bleaching ".

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 annealing brass requires heating it to about 660 F ( 350 C ), the heating must be done in such a way as to heat the neck to that temperature, while preventing the base of the case from being heated and losing its hardness.

Since the speed of sound increases as the temperature increases, the actual speed of an object traveling at Mach 1 will depend on the fluid temperature around it.

Since all atoms vibrate proportionally to their absolute temperature, a thermal neutron has the best opportunity to fission U-235 when it is moving at this same vibrational speed.

Since the electron is moving at a certain temperature ( Plank spectrum ) this noise source cannot be further eroded.

Since it's fairly close to the equator, the temperature doesn't fluctuate much between winter and summer.

Since the mid-1990s, starspot observations have been made using increasingly powerful techniques yielding more and more detail: photometry showed starspot growth and decay and showed cyclic behavior similar to the Sun's ; spectroscopy examined the structure of starspot regions by analyzing variations in spectral line splitting due to the Zeeman Effect ; Doppler imaging showed differential rotation of spots for several stars and distributions different from the Sun's ; spectral line analysis measured the temperature range of spots and the stellar surfaces.

Since the temperature of the rain was comparatively cool, it could be attributed to the hot pavement of the city.

Since the Laplace operator appears in the heat equation, one physical interpretation of this problem is as follows: fix the temperature on the boundary of the domain according to the given specification of the boundary condition.

Since the efficiency of a rocket engine is related to the square root of the temperature of the working fluid, the solid core design needs to be constructed of materials that remain strong at as high a temperature as possible.

Since by the principle of optimality the remaining stages use an optimal Af-stage policy with respect to Af, we may enter section Af of the table at this state Af and read off the optimal policy for stage Af and the resulting state Af.

Since esterification is highly reversible, the yield of the ester can be improved using Le Chatelier's principle:

Since its first publication in 1946 the principle has been accepted by Germany's Federal Constitutional Court in a variety of cases.

Since air is an insulator, in principle no other substance is needed to keep power where it should be.

Since the flow speed is zero at these points, by Bernoulli's principle the static pressure at these points is at a maximum.

Since bundle theory states that all concrete particulars are merely constructions or ' bundles ' of attributes, or qualitive properties, the substance theorist's indiscernibility argument claims that the ability to recognize numerically different concrete particulars, such as concrete objects, requires those particulars to have discernible qualitative differences in their attributes and that the metaphysical realist who is also a bundle theorist must therefore concede to the existence of ' discernible ( numerically different ) concrete particulars ', the ' identity of indiscernibles ', and a ' principle of constituent identity '.

Since the Heisenberg principle limits the precision of any measurement of the combination of an electron's momentum ( related to energy ) and its position, in a crystal effectively the available energy levels form a continuous band of allowed energy levels.

Since the early 1990s, the legitimatization of the principle of national self-determination has led to an increase in the number of conflicts within states, as sub-groups seek greater self-determination and even full secession, and as their conflicts for leadership within groups and with other groups and with the dominant state become violent.

Since this principle is a key premise in deriving the Liar paradox, the paradox is dissolved.

Since these are unknown in exact detail, cosmological models have been based on the cosmological principle, which states that the universe is homogeneous and isotropic.

Since the uncertainty principle is such a basic result in quantum mechanics, typical experiments in quantum mechanics routinely observe aspects of it.

Since it is absurd to have no logical method by which to settle on one hypothesis amongst an infinite number of equally data-compliant hypotheses, we should choose the simplest theory: " either science is irrational the way it judges theories and predictions probable or the principle of simplicity is a fundamental synthetic a priori truth " ( Swinburne 1997 ).

Since the Pauli exclusion principle forbids electrons from occupying the same state, any additional electron would be forced to occupy a positive-energy eigenstate, and positive-energy electrons would be forbidden from decaying into negative-energy eigenstates.

Since then a number of exceptions to this principle have been allowed.

The transfer principle states that true first order statements about R are also valid in * R. For example, the commutative law of addition, x + y = y + x, holds for the hyperreals just as it does for the reals ; since R is a real closed field, so is * R. Since for all integers n, one also has for all hyperintegers H. The transfer principle for ultrapowers is a consequence of Łoś ' theorem of 1955.

Since only the level spacing is determined by the correspondence principle, you could always add a small fixed offset to the quantum number --- L could just as well have been.

Since independence in 1971, the country has stressed its principle of friendship towards all, malice towards none in dictating its diplomacy.

Since the travel of the motion system is limited, a principle called ' acceleration onset cueing ' is used.

Since this new field concerns abstract rules, it can in principle address issues relevant to other fields of science.

) Since 1662 in Virginia, children born to enslaved mothers took their legal status as slaves under the principle of partus sequitur ventrem.

Since the Middle Ages, the semi-Salic principle was prevalent for the inheritance of feudal land in the Holy Roman Empire: inheritance was allowed through females when the male line expired.

Since the F – D distribution was derived using the Pauli exclusion principle, which allows at most one electron to occupy each possible state, a result is that < math > 0 <
