However, there are some exceptions: many of the stars in the constellation of Ursa Major ( including most of the Big Dipper ) are genuinely close to one another, travel through the galaxy with similar velocities, and are likely to have formed together as part of a cluster that is slowly dispersing.

However, their velocities are too large for them to remain gravitationally bound by their mutual attractions, implying the presence of either an additional invisible mass component, or an additional attractive force besides gravity.

However, either fission or fusion technologies can in principle achieve velocities far higher than needed for Solar System exploration, and fusion energy still awaits practical demonstration on Earth.

However, the velocities of plates range widely.

However, there has yet to be an established case of a planetary nebula discovered in an open cluster as based on a consistent set of distances, reddenings, and radial velocities.

Compression results in damage to the myelin sheath and manifests as delayed latencies and slowed conduction velocities However, normal electrodiagnostic studies do not preclude the presence of carpal tunnel syndrome, as a threshold of nerve injury must be reached before study results become abnormal and cut-off values for abnormality are variable.

However, in the many cases dealing with gases ( especially at higher velocities ) and those cases dealing with liquids with large pressure changes, the significant variations in density can occur, and the flow should be analysed as a compressible flow if accurate results are to be obtained.

However, it does require that each small locality change slowly enough to practically sustain its local Maxwell-Boltzmann distribution of molecular velocities.

However, in the last version of his theory in 1742 he shortened the related passages and ascribed " perfect elasticity or spring force " to the particles and on the other hand " imperfect elasticity " to gross matter, therefore the particles would be reflected with diminished velocities.

However, there have been some criticisms of the carbine, such as lower muzzle velocities and louder report due to the shorter barrel, additional stress on parts because of the shorter gas system, and a tendency to overheat faster than the M16A2.

However, it has recently been shown that they are not hot and that they owe their low seismic velocities to their distinct composition.

However, modern instrumentation shows that current velocities in deep water masses can be significant ( although much less than surface speeds ).

However, assuming the limit exists ( which it does for any bounded system, which fluid velocities certainly are ), there exists some such that integration from to is arbitrarily close to the average.

However, observations of spiral galaxies, particularly radio observations of line emission from neutral atomic hydrogen ( known, in astronomical parlance, as HI ), show that the rotation curve of most spiral galaxies flattens out, meaning that rotational velocities do not decrease with distance from the galactic center.

However, following the development of smokeless powder, the focus shifted to smaller-diameter bullets propelled at higher velocities, and the development of. 50 and larger calibers in handguns became uncommon.

However, if one does some simple thought experiments using the Newtonian definitions of momentum and energy, one sees that these quantities are not conserved in SR. One can rescue the idea of conservation by making some small modifications to the definitions to account for relativistic velocities.

However, certain Zarubintsy elements remained, found scattered throughout neighbouring areas of eastern Europe.

However, the Federalist electors scattered their second votes, resulting in the Democratic-Republican Party presidential candidate, Thomas Jefferson, receiving the second highest number of electoral votes and thus being elected Vice President.

However, this works only if the scattering is weak, i. e., if the scattered beams are much less intense than the incoming beam.

However, for all its self-consciousness and researched archaic vocabulary, the late epic was based on very old, scattered materials.

However, the relationship between the angles of the diffracted beams, the grating spacing and the wavelength of the light apply to any regular structure of the same spacing, because the phase relationship between light scattered from adjacent elements of the grating remains the same.

However, rumours of homosexuality were scattered around the country during and after his life by his political enemies, generally in a crudely homophobic fashion.

However, with the help of the Choctaw, traditional enemies of the Natchez, the French defeated and scattered the Natchez and their allies, the Yazoo.

However, summer, which is the driest seasion, primarily relies on precipitation from scattered diurnal thunderstorm activity and the Gulf of California monsoon.

However, electromagnetic radiation scattered by moving scattering centers does undergo a Doppler shift, which can be detected and used to measure the velocity of the scattering center / s in forms of techniques such as LIDAR and radar.

However, the traditional meaning is also to be found in the introduction to the Book of Mormon, in the statement that it is written to both " Jew " ( literal descendants of the House of Israel ) and " Gentile " ( those not descended from the House of Israel or those of the tribe of Ephraim scattered among the " Gentiles " throughout the earth ).

However, remains are also scattered throughout the islet, at Roi-Namur, and in various places throughout the atoll.

However, German infantry had already started to infiltrate Villers-Bocage and scattered house-to-house fighting and skirmishing broke out.

However, owing to its scattered composition and lack of focus, it was not his most successful refectory mural.

However, he had taken no steps towards fortifying the position ( e. g. by creating abatis or throwing up earthworks ), so the ground presented no obstacle to the American mounted troops, while scattered trees masked the British fire.

However, the battalion scattered throughout the area, with a number of paratroopers landing a considerable distance from the designated DZ ; Lieutenant-Colonel Terence Otway, the commander of the battalion, landed with the rest of his stick away from the drop-zone in a farmhouse being used as a command post by a German battalion, and after a brief fire-fight and helping other scattered paratroopers, only arrived at the drop-zone at 01: 30.

However, an unintended but beneficial result of these scattered drops was that the German defenders were greatly confused as to area and extent of the airborne landings.

However, the ride was upgraded in 2003 with laser-based plastic guns fitted to shoot LED lights scattered around the ride in order to deactivate scares.

However many flash based devices cannot rewrite part of a block, and they must first perform a ( slow ) erase cycle of each block before being able to re-write, so by putting all the writes in one block, this can help performance as opposed to writes scattered into various blocks, each one of which must be copied into a buffer, erased, and written back.

However, mines were also laid on the peninsula by the LTTE ; generally in ' nuisance minefields ', where the mines were laid at random, and scattered over wide areas.

However, as a result of the encounter, two Japanese destroyers collided and fell behind and the remainder became scattered.

However, Théoden found out that they had been scattered.

However, due to the unfavorable weather conditions of the state, and high ratio of pilots-to-population, over 1700 aircraft wreck sites are scattered throughout its domain.

However they were scattered among seventy different new units, none of which was a complete regiment.

However, a ravenous entity known as The Nameless One, who fed on the energy of the cosms, created several intelligent machines known as Darkness Devices and scattered them throughout the cosms.

However, the hydrogen-1 atom has no neutrons and a positive hydrogen ion has no electrons.

However, both protons and neutrons are composite particles composed of elementary particles called quarks.

However, the rapid capture of so many neutrons would provide needed direct experimental confirmation

However, this process cannot happen to a great extent in a nuclear reactor, as too small a fraction of the fission neutrons produced by any type of fission have enough energy to efficiently fission U-238 ( fission neutrons have a median energy of 2 MeV, but a mode of only 0. 75 MeV, meaning half of them have less than this insufficient energy ).

However, one neutron does collide with an atom of uranium-235, which then fissions and releases two neutrons and some binding energy.

However, neutrons almost invariably impact and are absorbed by other nuclei in the vicinity long before this happens ( newly created fission neutrons move at about 7 % of the speed of light, and even moderated neutrons move at about 8 times the speed of sound ).

However, too few of the neutrons produced by < sup > 238 </ sup > U fission are energetic enough to induce further fissions in < sup > 238 </ sup > U, so no chain reaction is possible with this isotope.

However, one neutron does collide with an atom of uranium-235, which then fissions and releases two neutrons and more binding energy.

However, both slow and fast neutrons react with the atomic nuclei of many elements upon collision with those nuclei, creating unstable isotopes and therefore inducing radioactivity in a previously non-radioactive material.

However, the intense pulse of high-energy neutrons that is generated is intended as the principal killing mechanism, not the fallout, heat or blast.

However, if the mass is critical only when the delayed neutrons are included, then the reaction can be controlled, for example by the introduction or removal of neutron absorbers.

However, if the gas from the primary coolant can be made radioactive by the neutrons in the reactor, or a fuel defect could still contaminate the power production equipment, it may be brought instead to a heat exchanger where it heats another gas or produces steam.

However, the neutrons released by fusion will fission U-238.

However, a small fraction ( about 0. 65 %) of neutrons in a typical power reactor comes from the radioactive decay of a fission product.

However, while plutonium was more expensive and harder to produce than uranium-235, it fissions faster, because it makes better use of the neutrons its fission produces.

However, it was found that natural uranium cannot sustain a chain reaction without a moderator to slow down the fast-moving neutrons given off by the fission.

However, when the lithium-7 isotope is bombarded with energetic neutrons, it captures a neutron then decays yielding an alpha particle, a tritium nucleus, and the captured neutron.

However, recent studies have indicated that, to the contrary, mono-energetic neutrons — particularly 14 MeV neutrons — can be used to quite accurately understand SEE cross-sections in modern microelectronics.

However a small additional source of neutrons is the fission products.
