However the development of heavy forms of reactive armour such as the Soviet, later Russian, Kontakt-5 which were designed to shear long rod penetrators, has prompted the reversal of this trend in the newest U. S. rounds.

However, it may be that proactive aggression is associated with low cortisol levels while reactive aggression may be accompanied by elevated levels.

However, theoretical calculations have shown that it could be quite reactive, so that it probably cannot be considered a noble gas.

However, if the hydrogen is molecular and thus not reactive, this permits the heavier atoms to react or remain bonded together, producing CO, CO < sub > 2 </ sub >, CN, etc.

However, fluorocarbons with double bonds ( fluoroalkenes ) and especially triple bonds ( fluoroalkynes ) are more reactive than their corresponding hydrocarbons.

However, the District of Columbia draft board exempted Buchanan from military service because of reactive arthritis, classifying him as 4-F.

However, today's modern reactive resin bowling balls now allow strokers to hit the " pocket " at a relatively high angle.

However, Eves was never able to gain control of the political agenda, and appeared indecisive and reactive on issues ranging from electricity restructuring to taxes.

However ; at some frequencies there may be a moderately reactive element within the loading, so the use of an antenna tuner may be beneficial when using modern, solid-state transmitters at anything approaching their rated power output.

However, if an unreactive alkylating agent is used ( e. g. an alkyl chloride ) then the rate of reaction can be greatly improved by the addition of a catalytic quantity of a soluble iodide salt ( which undergoes halide exchange with the chloride to yield a much more reactive iodide, a variant of the Finkelstein reaction ).

However, whether hypoxia leads to an increase or decrease in reactive oxygen species is unknown.

However, carboxylic acids tend to be less reactive than esters as electrophiles.

However, it operates not by inducing direct DNA damage, but by producing reactive oxygen species which damage DNA indirectly.

However, this breakdown of the ROS is not completely efficient ; some reactive residues are left in the brain to accumulate, contributing to neurotoxicity and cell death.

However, to be able to maintain 80 to 90 % hit probability on non-moving reactive army targets, this maximum shooting distance has to be reduced to at freezing point conditions or in Arctic winter conditions, when the muzzle velocity may drop to-i. e.

However, after the reactive armor has protected the vehicle from the primary attack, it is no longer " reactive " in that location ( since reactive armour is primarily a one-time defense solution ) and the location is left more vulnerable.

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, 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.
