However, cold fusion by this mechanism has not been generally accepted by the scientific community.

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, many endogenous retroviruses play important roles in host biology, such as control of gene transcription, cell fusion during placental development in the course of the germination of an embryo, and resistance to exogenous retroviral infection.

However Daniel P. Whitmire's 1975 analysis indicates that a ramjet may achieve net power via the CNO cycle, which produces fusion at a much higher rate (~ 10 < sup > 16 </ sup > times higher ) than the proton-proton chain.

However, very shortly thereafter, at twenty minutes after the Big Bang, the universe becomes too cool for any further nuclear fusion and nucleosynthesis to occur.

However, the record also made a shift from his traditional ballad-style compositions to a more risky fusion of music centered around traditional Latin sounds, epitomized by the song " Maria ".

However it may be particularly computationally expensive if significant processing is involved in data fusion, such as attempts to increase resolution.

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

However, in this fusion reaction 80 % of the energy, or 14 MeV, is in the motion of the neutron which, having no electric charge and being almost as massive as the hydrogen nuclei that created it, can escape the scene without leaving its energy behind to help sustain the reaction – or to generate x-rays for blast and fire.

However, newer 4th-and 5th-generation nuclear weapons designs including pure fusion weapons and antimatter catalyzed nuclear pulse propulsion-like devices are being studied extensively by the 5 largest nuclear weapon states.

However, some scholars have expressed the view that the most accurate explanation for modern-day United States culture and inter-ethnic relations can be found somewhere in a fusion of some of the concepts and ideas contained in the melting pot, assimilation, and Anglo-conformity models.

However, they made their announcements before any peer review of their work was performed, and no subsequent experiments by other researchers revealed any evidence of fusion.

However, since the most popular variant of satay is chicken satay in peanut sauce ( Sate Madura in Indonesia, Sate Kajang in Malaysia, and Thai chicken use peanut sauce ); in modern fusion cuisine the term " satay " has shifted to satay style peanut sauce instead.

However, other Velikovskian enthusiasts such as Ralph Juergens ( dec .), Earl Milton ( dec .), Wal Thornhill, and Donald E. Scott have embraced and developed these themes to propose a scenario where stars are powered not by internal nuclear fusion, but by galactic-scale electrical discharge currents.

However, he later supported the federalist system after seeing the carnage of the American Civil War ; he sought to avoid the same violent conflicts by maintaining a fusion of powers rather than a separation of powers.

However, not all of the muons are recycled: some bond with other debris emitted following the fusion of the nuclei ( such as alpha particles and helions ), removing the muons from the catalytic process.

However, because the proton and the deuteron would be more than 200 times farther apart in the case of the electronic HDO molecule than in the case of the muonic ( p-μ-d )< sup >+</ sup > molecular ion, Jackson estimates that the rate of p-d " electron "- catalyzed fusion ( eCF ) is about 38 orders of magnitude ( 10 < sup > 38 </ sup >) slower than the rate of p-d muon-catalyzed fusion ( μCF ), which Jackson estimates to be about 10 < sup > 6 </ sup > per second, so p-d " electron "- catalyzed fusions ( eCF ) would be expected to occur at a rate of about 10 < sup >- 32 </ sup > per second, meaning that one p-d " electron "- catalyzed fusion ( eCF ) might occur once every 10 < sup > 24 </ sup > years or so .</ ref >

However, the energy released with every d-d muon-catalyzed fusion reaction is only about 20 % or so of the energy released with every d-t muon-catalyzed fusion reaction.

However, the fusion was not completed.

However, the baseline design allows for a maximum of about 45 MJ of fusion energy release, due to the design of the target chamber.

However, in recent decades, for what doubtless are multiple reasons, an unannounced but nonetheless readily observable shift has occurred in both facets of national activity.

However, as a practicing historian, he, himself, has left few clues to the amount of professional scholarship that he used when writing history.

However, it seems axiomatic that the government has an obligation `` to exercise its mandate reasonably, equitably and with full regard for the disruptions which it inevitably causes ''.

However, because this vulnerability is mutual, it is to the advantage of neither side to destroy the opponent's cities, at least so long as the opponent has nuclear weapons with which to effect reprisal.

However, that is not all he has to do.

However, there are relatively few such political constituencies, and, as has been pointed out, there is seldom a clear-cut distinction between the educational interests of one social class and those of another.

However, electrostatic focus, important for many applications, has not been realized for these devices.

However, readers who accept Freud's findings and believe that he has solved completely the mystery of dreams, should ponder over the following words in his Interpretation Of Dreams, Chapter 1::

However, by cultivating a wine dealer and accepting his advice, one will soon enough ascertain whether he has any knowledge of wines ( as opposed to what he may have been told by salesmen and promoters ) and, better yet, whether he has a taste for wine.

However much football has been over-emphasized, the public likes to measure its collegiate favorites by the scoreboard, so, while Yale need never give its record a thought again since outscoring its opponents 694 to 0 in the season of 1888, Dartmouth had to wait until its championship team of 1925 for national recognition.

However, as Erickson has noted, the individual's failure to develop preliminary identities during infancy and childhood need not be irreversibly deterministic with respect to a given area of identity diffusion in his ( or her ) adolescence.

However, if the child has been constantly surrounded, during nursery and early school age, by peer groups ; ;

In a long commentary which he has inserted in the published text of the first act of the play, he says at one point: `` However, that experience never raised a doubt in his mind as to the reality of the underworld or the existence of Lucifer's many-faced lieutenants.

However, while Apollo has a great number of appellations in Greek myth, only a few occur in Latin literature, chief among them Phoebus ( ; Φοίβος, Phoibos, literally " radiant "), which was very commonly used by both the Greeks and Romans in Apollo's role as the god of light.

However, the monophyly of Cabozoa has been refuted and the monophylies of Archaeplastida and Chromalveolata are currently strongly challenged.

However, only a very small percentage of all these people has remained in Angola, either for personal reasons ( intermarriage ) or as professionals ( e. g. medical doctors ).

However, as has been pointed out by Alexis Manaster Ramer and Paul Sidwell ( 1997 ), Strahlenberg actually opposed the idea of a closer relationship between the languages which later became known as " Altaic "..

However, the method has been criticised as containing possible sources of error.

However, metal formation for condensed-phase astatine has also been suggested.

However, astatine has a few metallic characteristics as well, such as plating out on a cathode, coprecipitating with metal sulfides in hydrochloric acid, and forming a cation in strong acidic solutions.

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

However, it is the editor who has " the power to impose the dominant definition of the writer and therefore to delimit the population of those entitled to take part in the struggle to define the writer ".

However, this has now been replaced by a more professional exhibition space incorporating laser, video, slide shows, audio commentaries, and some interactive elements.
