Since the standard unit for expressing the mass of molecules or atoms ( the dalton or atomic mass unit ) is defined as 1 / 12 of the mass of a < sup > 12 </ sup > C atom, it follows that the molar mass of a substance, measured in grams per mole, is exactly equal to its mean molecular or atomic mass, measured in daltons ; which is to say, to the substance's mean molecular or atomic weight.

Since gravity only varies by a maximum of 0. 5 % over the Earth, and in most locations much less than that, the weight only had to be adjusted slightly.

Since 1973, this design has been built in glass-reinforced plastic with the same weight distribution as the original wooden version.

Since the New Brighton landscape is still recovering from the weight of the glaciers and going through post-glacial rebound and the turmoil this created, the landscape is poorly drained created the numerous lakes and rivers found in the city.

Since these engines typical need extra weight for traction purposes anyway the battery pack's weight is a negligible penalty.

Since the mass of systems must be measured with a weight or mass scale in a reference frame in which the system has zero momentum ( the center of momentum frame ), such a scale always measures the system's invariant mass.

Since this occurs dynamically as air flows over the aerospace object, it is convenient to alter Z, defined for an initial 30 gram mole of air, rather than track the varying mean molecular weight, millisecond by millisecond.

Since 1996, jerky has been selected by astronauts as space food several times for space flight due to its light weight and high level of nutrition.

Since WWI aircraft were largely built from wood to keep their weight down, BFW was equipped with the very latest joinery plant.

Since in humans the knee supports nearly the whole weight of the body, it is vulnerable to both acute injury and the development of osteoarthritis.

Since the elderly are often on multiple medications, they are at risk for taste disturbances increasing the chances of developing depression, loss of appetite, and extreme weight loss.

Since the surfaces of a wet clutch can be slippery ( as with a motorcycle clutch bathed in engine oil ), stacking multiple clutch discs can compensate for the lower coefficient of friction and so eliminate slippage under power when fully engaged.

Since the heat source that supplies thermal energy to the engine can thus be powered by virtually any kind of energy, heat engines are very versatile and have a wide range of applicability.

Since very few actual implementations of heat engines exactly match their underlying thermodynamic cycles, one could say that a thermodynamic cycle is an ideal case of a mechanical engine.

Since Id Software revealed their engine Id Tech 5, they call their engines " Id Tech ", followed by a version number.

Since 2001, trim levels are also indicated by including a number after the main index: '- 00 ' means base trim level, '- 01 ' means standard trim and '- 02 ' designates deluxe version ; for example, VAZ-21121-02 means Lada 112 hatchback with an 1. 6L SOHC engine and deluxe trim.

Since the piston is the main reciprocating part of an engine, its movement creates an imbalance.

Since the engine does not have an oil injection system, two-stroke oil has to be added to the fuel tank every time the car was filled up, at a 50: 1 or 33: 1 ratio of fuel to oil.

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 some Web search engines base the importance of sites on the number of different sites linking to them, referrer-log spam may increase the search engine rankings of the spammer's sites.

Since it provides the graphical elements surrounding the area in which the engine paints documents, the term chrome is sometimes used to refer to it.

Since the mid-1990s, Alenia Aermacchi has participated in programs for the supply of engine nacelles for civil aircraft.

Since the World Sportscar Championship was conceived there have been various regulations regarding bodywork, engine style and size, tyres and aerodynamics to which these cars must be built.

Since it is difficult to know that the rasterization engine will draw all pixels from front to back, there must be some way of ensuring that pixels close to the viewer are not overwritten by pixels far away.

Since the original source code to the game was lost by Rogue Entertainment, game engine recreations of Strife were created by Doom source port developers through reverse engineering, notably by Jānis Legzdiņš ( author of the Doom source port Vavoom ), Randy Heit ( author of ZDoom ), Samuel Villarreal ( author of SvStrife ) and James Haley ( author with Samuel Villareal of Chocolate Strife ).

Since 1976 Hodgkins has been served by the Pleasantview Fire Protection District which had its own humble beginnings with one engine in 1946 and has grown into a top-notch organization since then.

Since the transom may need to be cut down for the engine to fit properly, an engine well should be used to prevent low waves from splashing over the transom and flooding the boat.

Since the pressure on top of the engine is ambient, this means that base gives no overall thrust ( but it also means that this part of the nozzle doesn't lose thrust by forming a partial vacuum, thus the base part of the nozzle can be ignored at low altitude ).

Since fuel is not present in the combustion chamber until virtually the point at which combustion is required to begin, there is no risk of pre-ignition or engine knock.

Since then, improvements in both engine power and armament generally led to a loss of interest in this class for most nations.

Since the success and popularity of a search engine is determined by its ability to produce the most relevant results to any given search, allowing those results to be false would turn users to find other search sources.

Since WorldWideWeb was developed on and for the NeXTSTEP platform, the program used many of NeXTSTEP's components – WorldWideWeb's layout engine was built around NeXTSTEP's Text class.

* Since its introduction in 1975, the Honda Goldwing has utilized a boxer engine, a four-cylinder until 1987, and six-cylinders since.
