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 wave resistance and other impeding forces such as various types of drag ( physics ) on the hull are eliminated as the hull is lifted clear, turbulence and drag act only on the much smaller surface area of the hydrofoil and there is a marked increase in speed.

Since it is bearing surface that matters here, it is important that the bullets have a consistent bearing surface.

Since the beginning of civilization, people have used stone, ceramics and, later, metals found on or close to the Earth's surface.

Since surface area is a geometric notion, areas of congruent surfaces must be the same and area must depend only on the shape of the surface, but not on its position and orientation in space.

Since some of the outward drift is compensated by an inward drift on the same flux surface, there is a macroscopic equilibrium with much improved confinement.

Since 1953 however, AES has become a practical and straightforward characterization technique for probing chemical and compositional surface environments and has found applications in metallurgy, gas-phase chemistry, and throughout the microelectronics industry.

Since orbital energies are unique to an atom of a specific element, analysis of the ejected electrons can yield information about the chemical composition of a surface.

Since then, electric power has been used almost exclusively for powering submarines underwater, although diesel was used for powering them on the surface until the development of diesel-electric transmission by the US Navy in 1928.

Since the sides are also covered up to the spray rails, they are also rough-sanded in that area.
