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 engines convert heat from noncombustive processes into mechanical work, for example a nuclear power plant uses the heat from the nuclear reaction to produce steam and drive a steam engine, or a gas turbine in a rocket engine may be driven by decomposing hydrogen peroxide.

Some scientists and engineers have expressed reservations about nuclear power, including: Barry Commoner, S. David Freeman, John Gofman, Arnold Gundersen, Mark Z. Jacobson, Amory Lovins, Arjun Makhijani, Gregory Minor, Joseph Romm and Benjamin K. Sovacool.

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

Some of the helium-3 found in the terrestrial atmosphere is also a relic of atmospheric and underwater nuclear weapons testing, conducted by the three big nuclear powers before 1963.

Some scientists say that the 2011 Japanese nuclear accidents have revealed that the nuclear industry lacks sufficient oversight, leading to renewed calls to redefine the mandate of the IAEA so that it can better police nuclear power plants worldwide.

Some toponyms ( like Banana and Main Camp ) come from the nuclear testing period, during which at times over 4, 000 servicemen were present.

Some metals have specialized uses ; radioactive metals such as uranium and plutonium are used in nuclear power plants to produce energy via nuclear fission.

Some serious nuclear and radiation accidents have occurred.

Some in the UFO community, such as nuclear physicist Stanton Friedman, say there is no basis for the search and it is therefore unscientific.

Some Cold War strategists such as Henry Kissinger argue that a limited nuclear war could be possible between two heavily armed superpowers ( such as the United States and the Soviet Union ).

Some predict, however, that a limited war could potentially " escalate " into a full-scale nuclear war.

Some work is being done that would use nuclear resonance ; however there is no reliable evidence that any nuclear resonance processes have been scaled up to production.

Some other crucial contributions were Robert Christy's realization that implosive compression would facilitate nuclear detonation by significantly increasing the density of the plutonium sphere, Luis Alvarez's development of exploding-bridgewire detonators, which ensured that the explosive lenses would all fire simultaneously, and Bruno Rossi's RaLa experiments, which tested ( without plutonium ) various weapon designs to arrive at one that produced an accurately symmetrical implosion.

Some synthetic radioisotopes are extracted from spent nuclear reactor fuel rods, which contain various fission products.

Some first-strike weapons were deployed ; however like most nuclear weapons, they were never used.

Some of the issues considered within nuclear strategy include:

Some organizations such as nuclear power plants collect " as-found " calibration data before any routine maintenance is performed.

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

Some reactors do not use moderators to slow the neutrons.

Some of Vattenfall's most notable power generation plants include the 110 MW Lillgrund Wind Farm off the coast of Malmö, Sweden, the world's largest offshore wind farm at Thanet, UK, the nuclear reactors Brunsbuttel Nuclear Power Plant ( 67 % ownership ), Krummel Nuclear Power Plant ( 50 % ownership ), Brokdorf Nuclear Power Plant ( 20 % ownership ) in Germany, and the Forsmark Nuclear Power Plant and Ringhals Nuclear Power Plant in Sweden.

Some modern naval nuclear power reactors have, in addition to scramming, the ability to automatically run the electric motors in the inward direction at high speeds for a few seconds, thus driving the rods into the core a short distance while leaving them latched to their motors.

Some nuclear reactors use heavy water as cooling.

Some smaller reactors, such as the TOPAZ nuclear reactor, are built to minimize moving parts, and use methods that convert nuclear energy to electricity more directly, making them useful for space missions, but this electricity has historically been used for other purposes.

Some marine reactors run on relatively low-enriched uranium ( requiring frequent refueling ).

Some reactors circulate pressurized water, some use liquid metal, such as sodium, NaK, lead, or mercury ; others use gases ( see advanced gas-cooled reactor ).

Some reactors operate with the coolant in a constant state of boiling, using the generated vapor to turn turbines.

Some pressurized water reactors, for example, do not contain enough fuel of high enough enrichment to make a prompt critical assembly with the materials in the core.

Some reactors, such as the liquid metal and molten salt variants, use Thorium-232 fuel which is more abundant in nature than Uranium isotopes and requires no enrichment.

Some of the main competitors to General Atomics in the supply of research reactors are Areva of Europe and INVAP of Argentina.

Some early fast neutron reactors used mercury.

Some MFE work continued through this period, almost all of it using spheromaks as accessory devices for other reactors.

Some chaps that know an area well can make their way by landmarks, a tree here, a wash here, a boulder there.

Some of the poetic cadence of the older version certainly is lost in the newer one, but almost anyone, with a fair knowledge of the English language, can understand the meaning, without the necessity of interpretation by a Biblical scholar.

Some of the most dramatic successes of Communism in winning local support can be traced to the identification -- correct or not -- of Communist regimes with personal honesty and pro-Western regimes with corruption.

Some limitations of one element can be compensated for by a capability of another.

Some women can sit and sew, crochet, tat or knit by the hour, and look calm and relaxed and turn out beautiful work.

Some people can carve most anything out of a piece of wood.

Some turnpikes have not been in full operation long enough to prove what they can do.

Some interfaith tensions are not occasioned by theological differences at all, but by the need of men to have persons they can blame, distrust, denounce, and even hate.

`` Some can be lonely in a crowd '', Nogol said elaborately.

Some argue that no act of sharing, helping or sacrificing can be described as truly altruistic, as the actor may receive an intrinsic reward in the form of personal gratification.

Some amphibian toxins can be lethal to humans while others have little effect.

Some appellate courts, particularly supreme courts, have the power of discretionary review, meaning that they can decide whether they will hear an appeal brought in a particular case.

Some may suggest that it is probably advisable to use mouthwash at least an hour after brushing with toothpaste when the toothpaste contains sodium lauryl sulfate, since the anionic compounds in the SLS toothpaste can deactivate cationic agents present in the mouthrinse.

Some abugidas use a special symbol to suppress the inherent vowel so that the consonant alone can be properly represented.

Some axons can extend up to one meter or more while others stretch to as little as one millimeter ( inhibitory interneurons ).

Some details were changed slightly to allow more player choice-for example, players can be full Trump Artists without having walked the Pattern or the Logrus, which Merlin says is impossible ; and players ' psychic abilities are far greater than those shown in the books.

Some signs that are created with a 1 handshape can also be made using an L or a 5 handshape ( open handshape ).

Some opcodes require one or more operands as part of the instruction, and most assemblers can take labels and symbols as operands to represent addresses and constants, instead of hard coding them into the program.

Some distinctive accents can be found on the East Coast ( for example, in eastern New England and New York City ) partly because these areas were in close contact with England and imitated prestigious varieties of British English at a time when these were undergoing changes.

Some arguments from moral order suggest that morality is based on rationality and that this can only be the case if there is a moral order in the universe.

Some believe that Luke ’ s gospel can be seen to mirror the Jewish apologetic literature of the time which served to “ defend Jews against misunderstanding and persecution .” Acts is said to be a:

Some scholars believe that the apologetic view of Luke ’ s work is overemphasized and that it should not be regarded as a “ major aim of the Lucan writings .” While Munck believes that purpose of Luke ’ s work is not that clear-cut and sympathizes with other claims, he believes that Luke ’ s work can function as an apology only in the sense that it “ presents a defense of Christianity and Paul ” and may serve to “ clarify the position of Christianity within Jewry and within the Roman Empire .” Pervo disagrees that Luke ’ s work is an apology and even that it could possibly be addressed to Rome because he believes that “ Luke and Acts speak to insiders, believers in Jesus .” Freedman believes that Luke is writing an apology but that his goal is “ not to defend the Christian movement as such but to defend God ’ s ways in history .”

Some high performance permanent PSAs exhibit high adhesion values and can support kilograms of weight per square centimeter of contact area, even at elevated temperature.

Some remixes, particularly in dance music, can also be considered re-arrangements in this style.

Some people, however, can continue to lose potassium while on an ACE inhibitor.
