While general relativity replaces the scalar gravitational potential of classical physics by a symmetric rank-two tensor, the latter reduces to the former in certain limiting cases.

While this makes the weapon safer to carry and reduces the likelihood of an accidental discharge, it also means that there will be a longer delay before the officer can fire the weapon.

While there is little precipitation, giving the archipelago a steppe climate, plants still have good access to water because the cold climate reduces evaporation.

While this is intuitively false and is also false according to Carnap's theory of induction, observing non-ravens ( according to that same theory ) causes us to reduce our estimate of the total number of ravens, and thereby reduces the estimated number of possible counterexamples to the rule that all ravens are black.

The first study found a roughly linear relationship between length of membership and abstinence with reduced anxiety and increase self-esteem While the NA sample had higher anxiety than the non-addicted comparison groups, these levels were equivalent for those with three or more years membership, which is consistent with the hypothesis that NA membership reduces anxiety as well as substance use.

While this usually reduces the bulk, it does not reduce the extra weight of noise-cancelling headphones compared to traditional headphones.

While many male genital piercings are transurethral, the longer length of the male urethra reduces the risk of urinary tract infection due to transurethral piercings.

While the reduced function of the clipped bird's primaries prevent propulsion and therefore lift, this also reduces braking abilies, so clipped birds may crash-land at higher speeds than full-winged birds.

While allowing knockout as winning criterion, the protective equipment reduces the chances for it, and points are usually scored for clean techniques and techniques knocking the opponent off his feet.

While the inclusion of a covariate into an ANOVA generally increases statistical power by accounting for some of the variance in the dependent variable and thus increasing the ratio of variance explained by the independent variables, adding a covariate into ANOVA also reduces the degrees of freedom.

While periodontal infection has been linked with preterm birth, randomized trials have not shown that periodontal care during pregnancy reduces preterm birth rates.

While Detritus does not have much imagination and was originally not highly regarded even by other trolls, he has become fairly intelligent by troll standards, especially since the end of Men At Arms when Cuddy made a clockwork cooling helmet which reduces the effect heat has on the conductivity of Detritus ' silicon brain.

While electrostimulation techniques ( NEST ) have been used for twenty years to treat osteoarthritis in the knee, there is no evidence to show that it reduces pain or disability.

While the procedure generally reduces the over-all risk level for the remaining fetus or fetuses, reduction does have its own risks, including the possibility that one or more of the remaining fetuses will also die.

While oxygen is abundant in the bloodstream, HVS reduces effective delivery of that oxygen to vital organs due to low -- induced vasoconstriction and the suppressed Bohr effect.

While some funeral homes will use the hearse for these initial pickups, having vehicles for first calls and using the hearse solely for funerals reduces wear on hearses.

While contact with enemies reduces the player's health, it also slowly drains on its own, thus creating a time limit.

While the mechanism is not fully understood, it is likely to involve the production of electron – positron pairs, as ordinary matter gains tremendous energy while falling into a stellar remnant .< ref >

While playing, members exert energy on behalf of the team ( personal investment in the group ).

While people expected elements with higher atomic number to form from neutron bombardment of lighter elements, nobody expected neutrons to have enough energy to actually split a heavier atom into two light element fragments, and it was thought still more unlikely that slow neutrons could accomplish such a task.

While most of the energy of the signal is contained within f < sub > c </ sub > ± f < sub > Δ </ sub >, it can be shown by Fourier analysis that a wider range of frequencies is required to precisely represent an FM signal.

While perceived quality varied widely, the energy and enthusiasm involved tended to be communicated clearly to the readership, many of who were also fanzine contributors.

While the energy delivered to the target increases linearly with mass, it increases geometrically with the speed ( see the effect of the handle, below ).

While melting, any energy added breaks the hydrogen bonds between ice ( water ) molecules.

While encouraging the construction of large dams ( which Nehru called the " new temples of India "), irrigation works and the generation of hydroelectricity, Nehru also launched India's programme to harness nuclear energy.

While Liechtenstein produces only 15 % of its energy requirements.

While earthquakes are common in British Columbia and adjacent coastal waters, most are minor in energy release or are sufficiently remote to have little effect on populated areas.

While searching for the energy of the Black Lantern simultaneously dispatching various Doomsday ' clones ' created from the original to distract Earth's heroes by sending them after the other members of the Superman family with the aid of a robotic duplicate of Lois Lane created to give him an honest opinion on his actions, Luthor encountered Brainiac in space while attempting to alter the last of the Black Lantern energy, acting upon an unspoken theory of his.

While the work on radioactivity by Becquerel and Marie Curie predates this, an explanation of the source of the energy of radioactivity would have to wait for the discovery that the nucleus itself was composed of smaller constituents, the nucleons.

While hydrogen fusion can occur in a stable manner on the surface of the white dwarf for a narrow range of accretion rates, for most binary system parameters the hydrogen burning is thermally unstable and rapidly converts a large amount of the hydrogen into other heavier elements in a runaway reaction, liberating an enormous amount of energy, blowing the remaining gases away from the white dwarf's surface and producing an extremely bright outburst of light.

While typical chemical reactions release energies on the order of a few eVs ( e. g. the binding energy of the electron to hydrogen is 13. 6 eV ), nuclear fission reactions typically release energies on the order of hundreds of millions of eVs.

While the reason for this underabundance is not yet fully understood, one possibility is that convection in stellar interiors can ' overshoot ' into regions where radiation is normally the dominant mode of energy transport.
