Because they do not interact with electromagnetism they cannot be seen directly, and because they do not interact with the strong nuclear force they do not react strongly with atomic nuclei.

Because of their ability to harness the power of what is essentially a continuous nuclear fission explosion, NSWRs would have both very high thrust and very high exhaust velocity, a rare combination of traits in the rocket world, meaning that the rocket would be able to accelerate quickly as well as be extremely efficient in terms of propellant usage.

Because of the downward tilt of the Earth's magnetic field at high latitudes, the area of peak field strength is a U-shaped region to the equatorial side of the nuclear detonation.

Because of the similarity between solar-induced geomagnetic storms and nuclear E3, it has become common to refer to solar-induced geomagnetic storms as " solar EMP.

Because of the need for great security, all production facilities and nuclear reactors would be government-owned, while all technical information and research results would be under Commission control.

Because this procedure of recomputing the electronic wave functions as a function of an infinitesimally changing nuclear geometry is reminiscent of the conditions for the adiabatic theorem, this manner of obtaining a PES is often referred to as the adiabatic approximation and the PES itself is called an adiabatic surface.

Because of this and because the mutation rate of animal mtDNA is higher than that of nuclear DNA, mtDNA is a powerful tool for tracking ancestry through females ( matrilineage ) and has been used in this role to track the ancestry of many species back hundreds of generations.

Because of its remote location, Fort Greely was chosen as one of the first US military posts to have a compact, nuclear power reactor to generate heat and electricity, under the auspices of the Army Nuclear Power Program.

Because the light water reactors would require enriched uranium to be imported from outside North Korea, the amount of reactor fuel and waste could be more easily tracked, making it more difficult to divert nuclear waste to be reprocessed into plutonium.

Because of a well-known system of aquifers and sand mines, this area was selected for " project dribble " to be the site of nuclear tests by the US government during 1961 to 1968 to measure seismic activity.

Because of delays in construction, a number of nuclear power plants in the United States have resorted to dry cask storage of waste on-site indefinitely in nearly impervious steel and concrete casks.

Because the rake angle Af at the tip of the knife is very much smaller ( or even negative ) when compared to the value of **yc for the major portion of the knife, a very rapid increase in cutting force with thickness will result.

Because of the need for literate and skilled young men to handle modern weapons, the army has served as a training ground for a large reserve force.

Because the projected horizontal motion in the rotating frame is a circular motion, the ball's motion requires an inward centripetal force, provided in this case by a fictitious force that produces the apparent spiral motion.

Because centrifugal force increases according to the square of, one would expect gravity to be cancelled for an object travelling 17 times faster than the Earth's rotation, and in fact satellites in low orbit at the equator complete 17 full orbits in one day.

Because of the absence of a net force in the azimuthal direction, conservation of angular momentum allows the radial component of this equation to be expressed solely with respect to the radial coordinate, r, and the angular momentum, yielding the radial equation ( a " fictitious one-dimensional problem " with only an r dimension ):

Because the strength of the force falls off rapidly with distance, it is only measurable when the distance between the objects is extremely small.

Because the Earth completes only one rotation per day, the Coriolis force is quite small, and its effects generally become noticeable only for motions occurring over large distances and long periods of time, such as large-scale movement of air in the atmosphere or water in the ocean.

Because the Congolese army had been in disarray since the mutiny, Lumumba wanted to use the UN troops to subdue Katanga by force.

Because an interaction results in fermions attracting and repelling each other, an older term for " interaction " is force.

Because of the Ethiopian refusal to abide by the Italian version of the treaty and despite economic handicaps at home, the Italian government decided on a military solution to force Ethiopia to abide by the Italian version of the treaty.

Because the unified Swiss Code of Criminal Procedure ( set to enter into force in 2011 ) does not provide for jury trials or lay judges, however, they are likely to be abolished in the near future.

Because there are no sporting rules, individuals trained in Krav Maga are not limited to techniques that avoid severely injuring their opponents, but training and sparring drills provide maximum safety to the students by the use of protective equipment and the use of reasonable force.

Because this is a cross product, the force is perpendicular to both the motion of the particle and the magnetic field.

Because the local governments did not officially receive the bull, it was not, technically, in force in those areas – an example of the interference of states in religious affairs common before the 20th century.

Because this integral depends on the trajectory of the point of application of the force and torque, this calculation of work is said to be " path dependent.

Because the Ringworld spins fast enough to provide gravity, once the police station and ship are on the underside, centrifugal force pushes them outward from the ring into open space.

Because of his health problems, Jordan did not work at full force on the final installment A Memory of Light ( later split into three volumes beginning with The Gathering Storm ), but blog entries confirmed that he continued work on it until his death, and he shared all of the significant plot details with his family not long before he died.

Because there are few jobs, a large proportion of the work force has left to seek employment overseas.

Because, in their view, traditional religions were failing to meet the needs of their day, the signers of 1933 declared it a necessity to establish a religion that was a dynamic force to meet the needs of the day.

Because payment of tax is compulsory and enforced by the legal system, some political philosophies view taxation as theft ( or as slavery, or as a violation of property rights ), or tyranny, accusing the government of levying taxes via force and coercive means.

Because Volta believed that the electromotive force occurred at the contact between the two metals, Volta's piles had a different design than the modern design illustrated on this page.
