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

However, any such suggestion accounts for only some of the difficulties in hearing tone, or in developing a realistic attitude about tone, but not for the analytic difficulties that occur even when tone is meticulously recorded.

However, he had a strong interest in the fledgling motion picture industry and when Essanay Studios offered him the opportunity to become a scriptwriter, he took the job.

However, it would require all data transmission to send eight bits when seven could suffice.

However, the Greeks thought of the two qualities as complementary: the two gods are brothers, and when Apollo at winter left for Hyperborea, he would leave the Delphic oracle to Dionysus.

However, when applied to data from non-randomized experiments or observational studies, model-based analysis lacks the warrant of randomization.

However, when anxiety becomes overwhelming, it may fall under the classification of an anxiety disorder.

However, when forced to choose between Poirot and his wife in that novel, he initially chooses to betray Poirot to the Big Four so that they would not torture and kill his wife.

However, in general, the books only feature mental battles when there is some reason for mind-to-mind contact ( for example, Trump contact ) and magic or Trump is involved in all three of the above conflicts, so it is not clear whether Zelazny intended his characters to have such a power ; the combination of Brand's " living trump " powers and his high Psyche ( as presented in the roleplaying game ) would have guaranteed him victory over Corwin.

However, its intermediate result storage mechanism, a paper card writer / reader, was unreliable, and when inventor John Vincent Atanasoff left Iowa State College for World War II assignments, work on the machine was discontinued.

However, he continued his slave trading career until 1754 or 1755, when he ended his seafaring altogether and began studying Christian theology.

However, when campaigning against Germanic tribes of Germania, Alexander attempted to bring peace by engaging in diplomacy and bribery.

However, when the time came, Anna quickly and surreptitiously mobilized the remainder of the family and took refuge in the Hagia Sophia.

However, this situation changed drastically when Alexios ' first son John II Komnenos was born in 1087: Anna's engagement to Constantine was dissolved, and she was moved to the main Palace to live with her mother and grandmother.

However, when an Athenian took up an office, he was regarded as ' serving ' the people.

However, the allophone phenomenon becomes obvious when speakers switch languages.

However, when there are complementary allophones of a phoneme, so that the allophony is significant, things become more complicated.

However, in some situations, especially when deep behind enemy lines, the actual attack will be carried out by a platoon, a company-sized unit will be deployed to support the attack group, setting up and maintaining a forward patrol harbour from which the attacking force will deploy, and to which they will retire after the attack.

However, in 2004, Maher concluded that " Physical treatments, such as acupuncture, backschool, hydrotherapy, lumbar supports, magnets, TENS, traction, ultrasound, Pilates therapy, Feldenkrais therapy, Alexander technique, and craniosacral therapy are either of unknown value or ineffective and so should not be considered " when treating lower back pain with an evidence-based approach.

However, the atomic mass in u of pure isotope atoms is quite close ( always within 1 %) to its simple mass number.

IUPAC prefers that isotope symbols be written in superscript notation when practical, for example < sup > 12 </ sup > C and < sup > 235 </ sup > U. However, other notations, such as carbon-12 and uranium-235, or C-12 and U-235, are also used.

However, the exact mass of hydrogen-1 ( the most common hydrogen isotope ) is 1. 00783, and the exact mass of oxygen-16 ( the most common oxygen isotope ) is 15. 9949, so the mass of the most common molecule of water is 18. 01056 u.

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, construction of an isochron does not require information on the original compositions, using merely the present ratios of the parent and daughter isotopes to a standard isotope.

However, it is a major concern to those in the field of nuclear proliferation because it may be cheaper and more easily hidden than other methods of isotope separation.

However, recent advances in mass spectrometry ( i. e. multiple-collector inductively coupled plasma mass spectrometry ) now enable the measurement of isotope ratios in heavier stable elements, such as iron, copper, zinc, molybdenum, etc.

This is because < sup > 238 </ sup > U is much more stable than < sup > 235 </ sup > U or < sup > 234 </ sup > U, as the half-life of each isotope reveals: 4. 468 × 10 < sup > 9 </ sup > years for < sup > 238 </ sup > U compared to 7. 038 × 10 < sup > 8 </ sup > years for < sup > 235 </ sup > U and 245, 500 years for < sup > 234 </ sup > U. However, the natural abundance of a given isotope is also affected by the probability of its creation in nucleosynthesis ( as in the case of samarium ; radioactive < sup > 147 </ sup > Sm and < sup > 148 </ sup > Sm are much more abundant than stable < sup > 144 </ sup > Sm ) and by production of a given isotope by natural radioactive isotopes ( as in the case of radiogenic isotopes of lead ).

However, it should be distinguished from the molecular mass ( also known as molecular weight ), which is the mass of one molecule ( of any single isotopic composition ) and is not directly related to the atomic mass, the mass of one atom ( of any single isotope ).

However, this isotope has a day half life of 59 years, and thus in the supernova grains derived from such explosians, is soon converted entirely to calcium-44.

However, it is reported that in the case of vinyl alcohol, formation of a stabilized enol form can be accomplished by controlling the water concentration in the system and utilizing the kinetic favorability of the deuterium produced kinetic isotope effect ( k < sub > H < sup >+</ sup ></ sub >/ k < sub > D < sup >+</ sup ></ sub >

However, with his friend Otto Frisch, a fellow German scientist living in exile in England, Peierls then began to examine the neutron cross-section of uranium-235, the rare lighter isotope that makes up only 0. 7 % of natural uranium, the rest being uranium-238.

However, due to the relative rarity of that isotope, this process lasts only a tiny fraction of the star's lifetime, and hence most brown dwarfs would have ceased fusion long before their discovery.

However, the high abundance of this isotope would make war quite unlikely.

However, later study challenged the universality of the successive capture theory since no element was found to have a stable isotope with an atomic mass of five or eight, hindering the production of elements beyond helium.

However, since the other 90 % of radiation ( beta radiation ) causes tissue damage without contributing to any ability to see or " image " the isotope, other less-damaging radioisotopes of iodine are preferred in situations when only nuclear imaging is required.

However, this may again have some side effects like the deterioration of the target properties ( melting for a serious temperature rise ) or the decrease of absolute isotope production due to the shrinkage of the amount of target.

However, modern strontium isotope analysis of the human remains recovered from the tomb attributed to him indicate that K ' inich Yax K ' uk ' Mo ' spent his formative years much closer to Copán, at Tikal, and had not himself lived at Teotihuacan.

However, if this happens, there can be no stable isotope with an even number of neutrons and an even number of protons.
