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

However, the use of advanced nuclear magnetic resonance methods to directly measure the mobility of water in living cells contradicts this idea, as it suggests that 85 % of cell water acts like that pure water, while the remainder is less mobile and probably bound to macromolecules.

However, this understanding of original sin is what lies behind the Christian emphasis on the need for spiritual salvation from a spiritual Saviour, who can forgive and set aside sin even though humans are not inherently pure and worthy of such salvation.

However, in the 1930s Gödel's incompleteness theorems convinced many mathematicians that mathematics cannot be reduced to logic alone, and Karl Popper concluded that " most mathematical theories are, like those of physics and biology, hypothetico-deductive: pure mathematics therefore turns out to be much closer to the natural sciences whose hypotheses are conjectures, than it seemed even recently.

However Lenard's results were qualitative rather than quantitative because of the difficulty in performing the experiments: the experiments needed to be done on freshly cut metal so that the pure metal was observed, but it oxidised in a matter of minutes even in the partial vacuums he used.

However, as it is composed of both pure goodness and pure evil, it might have enough power to rival that of God Himself.

However, not only because of the message conveyed, but also Bearden ’ s vernacular realism represented in the work makes The Visitation noteworthy ; Bearden describes two figures in The Visitation somewhat realistically but does not fully follow the pure realism by distorting and exaggerating some parts of their body, to “ convey an experiential feeling or subjective disposition .” Bearden ’ s quotation also demonstrates his supportive view to vernacular realism: “ the Negro artists must not be content with merely recording a scene as a machine.

However, such pure systems are rare.

However, the show's purpose today has changed to pure entertainment.

However, this influence is also often shallow and purely aesthetic in nature, ignoring some of Peckinpah's greatest strengths in favor of pure imitation of his stylish approach to cinematic violence.

However, very pure tungsten, though still hard, is more ductile, and can be cut with a hard-steel hacksaw.

However, Lord Henry's cynical outlook on life, and hedonistic nature seems to be in keeping with the idea of the devil's role, that of the temptation of the pure and innocent qualities which Dorian exemplifies at the beginning of the book.

However, it is not a pure genre and is very frequently coupled with elements of other genres, such as the shooter elements in Contra, the adventure elements of Flashback or the RPG elements of Castlevania: Symphony of the Night.

However, pure H < sub > 2 </ sub > O is tasteless and odorless.

However, in the pure Gauss – Bonnet gravity ( a modification to general relativity involving extra spatial dimensions which is sometimes studied in the context of brane cosmology ) exotic matter is not needed in order for wormholes to exist — they can exist even with no matter.

However, pure carving and pure stemming are used in certain circumstances.

However, the Austrian Prime Minister, Bruno Kreisky, argued on behalf of Brandt: " It is a question of whether it is better to be pure or to have greater numbers ".

" However, the Yellowstone Park Bison Herd were pure plains bison, and not any of the other previously suggested subspecies.

However, the possible absence of a center of symmetry not only moves the hydrogen atom off Af, but also allows the oxygen atoms to become nonequivalent, with Af at Af and Af at Af ( space group Af ), where Af represents the oxygens on one side of the Af layers and Af those on the other side.

However, any oxygen nonequivalence would shorten either the already extremely short Af interlayer distance of 2.55 A or the non-hydrogen-bonded Af interlayer interactions which are already quite short at 2.58 Aj.

However, reactive oxygen species also have useful cellular functions, such as redox signaling.

However, unless the airflow is adjusted as well, the flame temperature will decrease because an increased amount of gas is now mixed with the same amount of air, starving the flame of oxygen.

However, iron is the most abundant element ( by mass ) making up the Earth, and oxygen is the most common element in the Earth's crust.

However, it should be noted that because of risks associated with oxygen toxicity, divers tend not to utilize nitrox at greater depths where more pronounced narcosis symptoms are more likely to occur.

However, the singlet form of oxygen is the higher-energy form of the molecule.

However, many of the physical properties of water and ice are controlled by the formation of hydrogen bonds between adjacent oxygen and hydrogen atoms.

However, the atmosphere was found to be in a stable condition close to its chemical equilibrium, with very little oxygen, methane, or hydrogen, but with an overwhelming abundance of carbon dioxide.

However with the help of the correct atomic weights for copper and oxygen ( which Dalton did not know ), it is determined that the formulas of these two oxides are Cu < sub > 2 </ sub > O and CuO.

However, the oxygen molecule, because of the involvement of π-orbitals, is an exception important for the life-sciences.

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, despite their age, they are pretty vulnerable to terrestrial environment: water, salt, oxygen attack the meteorites as soon they reach the ground.

However, " relatively high ," in the case of ozone, is still very small with regard to ordinary oxygen, and is less than ten parts per million, with the average ozone concentration in Earth's atmosphere being only about 0. 6 parts per million.

However, there are some types of bacteria that carry out anoxygenic photosynthesis, which consumes carbon dioxide but does not release oxygen.

However, nuclear submarines run " open loop "— extracting oxygen from seawater, and typically dumping carbon dioxide overboard, although they recycle existing oxygen.

However, he was one of the first scientists to recognize that the oxygen, nitrogen and carbon dioxide in the Earth's atmosphere result from biological processes.

However, the hearts of some other arthropods ( including spiders and crustaceans such as crabs and shrimp ) and some other animals pump hemolymph, which contains the copper-based protein hemocyanin as an oxygen transporter similar to the iron-based hemoglobin in red blood cells found in vertebrates.

However, he chose to fix the atomic weight of oxygen as 100, an innovation that did not catch on.

However the chemical convenience of having oxygen as the primary atomic weight standard became ever more evident with advances in analytical chemistry and the need for ever more accurate atomic weight determinations.

However, of most importance is gas exchange via fine unbranched tubes, the tracheae, which draw oxygen from the surface deep into the various organs, particularly the heart.

However, C. botulinum tolerates traces of oxygen due to the enzyme superoxide dismutase ( SOD ) which is an important antioxidant defense in nearly all cells exposed to oxygen.

However, the dive has taken too long for Bud to return to the top of the trench before the oxygen in the liquid runs out.
