Some < sup > 238 </ sup > U atoms, however, could absorb another two neutrons ( for a total of 17 ), resulting in < sup > 255 </ sup > Es, as well as in the < sup > 255 </ sup > Fm isotope of another new element, fermium .< ref >< sup > 254 </ sup > Es, < sup > 254 </ sup > Fm and < sup > 253 </ sup > Fm would not be produced because of lack of beta decay in < sup > 254 </ sup > Cf and < sup > 253 </ sup > Es </ ref > The discovery of the new elements and the associated new data on multiple neutron capture were initially kept secret on the orders of the U. S. military until 1955 due to Cold War tensions and competition with Soviet Union in nuclear technologies.

Some reactors are used for the neutron irradiation of samples for radioisotope production for a range of purposes.

Some processes involving neutrons are notable for absorbing or finally yielding energy — for example neutron kinetic energy does not yield heat immediately if the neutron is captured by a uranium-238 atom to breed plutonium-239, but this energy is emitted if the plutonium-239 is later fissioned.

Some of the neutrons wander past the acrylic vessel into the light water, and since light water has a very large cross section for neutron capture these neutrons are captured very quickly.

Some of the more important of these include the r process, which involves rapid neutron captures, the rp process, which involves rapid proton captures, and the p process ( sometimes known as the gamma process ), which involves photodisintegration of existing nuclei.

: Some particle accelerator-based neutron generators exist that work by inducing nuclear fusion between beams of deuterium and / or tritium ions and metal hydride targets which also contain these isotopes.

Some designs add neutron reflectors or absorbers.

Some early evidence for nuclear fission was the formation of a short-lived radioisotope of barium which was isolated from neutron irradiated uranium, with a half-life of 12. 8 days, are major fission products of uranium.

Some common experimental applications of these studies are in liquid helium ( He-3 and He-4 ), and of the interior of neutron stars and the quark-gluon plasma.

Some interpretations claim that understanding the interference effect requires one to concede that a single neutron takes both paths through the interferometer at the same time ; a single neutron would " be in two places at once ", as it were.

Some materials are more subject to neutron activation than others, so a suitably chosen low-activation material can significantly reduce these problems.

Some early fast neutron reactors used mercury.

Some of this neutron

Some other actinides need more than one neutron capture before arriving at an isotope which is both fissile and long-lived enough to probably be able to capture another neutron and fission instead of decaying.

Some thorium-cycle reactor designs try to protect Pa-233 from further neutron capture producing Pa-234 and U-234 which are not useful as fuel.

Some < sup > 155 </ sup > Eu is also produced by successive neutron capture on < sup > 153 </ sup > Eu ( nonradioactive, 350 barns thermal, 1500 resonance integral, yield is about 5 times as great as < sup > 155 </ sup > Eu ) and < sup > 154 </ sup > Eu ( half-life 8. 6 years, 1400 barns thermal, 1600 resonance integral, fission yield is extremely small because beta decay stops at < sup > 154 </ sup > Sm ); however the differing cross sections mean that both < sup > 155 </ sup > Eu and < sup > 154 </ sup > Eu are destroyed faster than they are produced.

Some of Boötes ' stars were traditionally described as representing the club ( Greek, Κολλοροβος ) of Boötes.

Some stars, such as the nearby star 82 Eridani, were named in a major southern-hemisphere catalog called Uranometria Argentina, by Benjamin Gould, and are not true Flamsteed numbers, and should properly contain a G, as in 82 G. Eridani.

Some have pointed out that the constellation is on the celestial equator and have suggested that the stars rotating in the night sky may have been associated with Frigg's spinning wheel.

Some stars in globular clusters appear to be as old as the universe itself ( by entirely different measurement and analysis methods ).

Some galaxies have been observed to form stars at an exceptional rate, known as a starburst.

Some new helium is being created currently as a result of the nuclear fusion of hydrogen in stars.

Some fraction of elements beyond helium were created in the Big Bang, as the protons and neutrons collided with each other ( lithium, beryllium, and perhaps some boron ), but all of the " heavier elements " ( heavier than carbon, element number 6 ) that we see today, were created inside of stars during a series of fusion stages, such as the proton-proton chain, the CNO cycle and the triple-alpha process.

Some nebulae are formed as the result of supernova explosions, the death throes of massive, short-lived stars.

Some of the biggest stars of this era were Kareem Abdul-Jabbar, Rick Barry, Dave Cowens, Julius Erving, Elvin Hayes, Walt Frazier, Moses Malone, Artis Gilmore, George Gervin, Dan Issel, and Pete Maravich.

Some astronomers believe the two types of star clusters form via the same basic mechanism, with the difference being that the conditions that allowed the formation of the very rich globular clusters containing hundreds of thousands of stars no longer prevail in the Milky Way.

Some open clusters contain hot blue stars which seem to be much younger than the rest of the cluster.

Some of the bigger stars in the industry, such as Shawn Michaels, Triple H, The Undertaker, and The Sandman, can perform ring entrances lasting up to three minutes or more.

Some stars may fuse helium in core hot-spots, causing an unstable and uneven reaction as well as a heavy stellar wind.

* Some stars in entirely different constellations may have the same name: Algenib in Perseus and Algenib in Pegasus ; Gienah in Cygnus and Gienah in Corvus, Alnair in Grus and Alnair in Centaurus.

Some Italian Western films were made as vehicles for musical stars, like Ferdinando Baldi's Rita of the West featuring Rita Pavone and Terence Hill.

Some of which include Annie ( 1982 ), Clue ( 1985 ), and most notably, the 1990 horror miniseries Stephen King's It in which he stars as " Pennywise the Dancing Clown ", an alternate physical appearance of the titular antagonist, It.

Some lighter stars also form these elements in the outer parts of the stars over long periods of time, by absorbing energy from fusion in the inside of the star, by absorbing neutrons that are emitted from the fusion process.

Some astrologers also take note of minor planetary bodies, fixed stars, asteroids ( for example, Chiron ) and other mathematically calculated points and angles such as the vertex, equatorial ascendant, etc.

Some crinoids, however, namely the feather stars, are also highly motile ( able to move themselves ).

Some burrowing sea stars poke their tube feet through the surface of the sand or mud above them into the water column and use them to attain oxygen from the water column.

Some stars, for example, seem to have magnetic fields, fossil stellar magnetic fields left over from their period of formation, while others seem to generate the field anew frequently.

Some of these elements, particularly those lighter than iron, are thought to be delivered to the interstellar medium in the last stages of evolution of dying low mass stars, in the non-explosive ejection of the outer envelope gases of plantetary nebulae before these stars continue to form white dwarfs.

Some skaters are able to rotate in both directions.

Some stands allow the feet of the tripod to be adjusted to tilt the stand, or to allow the tripod to rotate on the stand to allow the feet to be positioned among other stands.

Some smaller instruction classes include the shift / rotate instructions and the procedure call instructions.

Some slingers will rotate the sling slowly once or twice to seat the projectile in the cradle.

Some versions allow the player to rotate the playing field 90 degrees clockwise or counter-clockwise, which causes one of two things to happen:

Some versions of this design allowed the bell to also rotate forward, projecting the sound to the front of the band.

Some clients rotate between residences in different cities when attending public events or meetings to prevent being tailed home or to a private location.

Some of the largest and most modern Ferris wheels have cars mounted on the outside of the rim, and electric motors to independently rotate each car to keep it upright.

Some blue stragglers have been observed to rotate quickly, with one example in 47 Tucanae observed to rotate 75 times faster than the Sun, which is consistent with formation by collision.

Some teams rotate captains rather than keep one for an extended period of time ( the Minnesota Wild rotated captaincy every one or two months until the 2009-10 season, when Mikko Koivu was named the first permanent captain since the franchise began ).

Some keychains allow one or both ends the ability to rotate, keeping the keychain from becoming twisted, while the item is being used.
