However in Superman III ( 1983 ) it is said that Kryptonite is an alloy made up of 15. 08 % plutonium, 18. 06 % tantalum, 27. 71 % xenon, 24. 02 % promethium, 10. 62 % dialium, 3. 94 % mercury, and 0. 57 % of an unknown substance.

However, in accordance with periodic trends, radon has a lower electronegativity than the element one period before it, xenon, and is therefore more reactive.

However, Ramsauer and Townsend observed that for slow-moving electrons in argon, krypton, or xenon, the probability of collision between the electrons and gas atoms obtains a minimum value for electrons with a certain amount of kinetic energy ( about 0. 7 electron volts for xenon gas ).

However, most makes of nitrous systems combined with unsuitable intake designs, often result in distribution problems and / or intake backfires.

However, many people took the lyrics at face value, interpreting the song as a paean to masturbation and sadomasochism, or a reference to inhaling nitrous oxide from whipped cream cans ( taken from the name " whip-it ", used to describe the nitrous chargers for whipped cream dispensers ).

However, silane produces a lower-quality oxide than the other methods ( lower dielectric strength, for instance ), and it deposits nonconformally.

However, it tarnishes quickly in moist air, forming a loosely adhering gadolinium ( III ) oxide ( Gd < sub > 2 </ sub > O < sub > 3 </ sub >), which spalls off, exposing more surface to oxidation.

However, the soda makes the glass water soluble, which is usually undesirable, so lime ( calcium oxide, generally obtained from limestone ), some magnesium oxide ( MgO ) and aluminium oxide ( Al < sub > 2 </ sub > O < sub > 3 </ sub >) are added to provide for a better chemical durability.

However, when exposed to moist air at room temperature, lanthanum oxide forms a hydrated oxide with a large volume increase.

However, it is disadvantaged by it being necessary for the base metal ( or ceramic ) having to undergo some wear first to generate sufficient oxide debris.

However, it is slow to react with water and air, because it forms a passive and protective oxide coating that protects it from further reaction.

However, like the other lanthanides, the most common oxidation state is + 3, seen in its oxide, halides and other compounds.

However, alkylating agents ( e. g. ethylene oxide ), and 10 % bleach are effective against endospores.

However, stabilization of cubic zirconium oxide had been realized early on, with the synthetic product stabilized zirconia introduced in 1930.

However, commercial monazite sands typically contain between 6 and 12 % thorium oxide.

However, not all heavy elements make this transition as some chalcophilic heavy elements bind into low-density silicate and oxide compounds, which differentiate in the opposite direction.

However, the development of strontium oxide aluminate, with a luminance approximately 10 times greater than zinc sulfide, has relegated most zinc sulfide based products to the novelty category.

However, because sexual stimulation is required to initiate the local penile release of nitric oxide, tadalafil's inhibition of PDE5 will have no effect without direct sexual stimulation of the penis.

However, in 2006, Henry Spencer stated that the phenomenon of spontaneous cold welding in outer space is " basically a myth ", pointing out that " there are no documented cases of it actually occurring in orbit, except in experiments deliberately designed to provoke it ( with susceptible materials, great care to avoid contamination, and deliberate mechanical removal of oxide layers, etc .).

However, already D. C. Brodie was aware of the highly lamellar structure of thermally reduced graphite oxide in 1859.

However, recent developments with new catalysts based on Ruthenium ( IV ) oxide were developed by Sumitomo and the first detailed mechanistic study can be found in J. Catal.

However, demand for emery has decreased with the development of sintered carbide and oxide materials as abrasives.

However, the process was tweaked with a 6th metal layer to allow for better density and speed, and the transistors have a slightly shorter gate length and thinner gate oxide.

( OCLC 313492506 )</ ref > However, increasing the ripple current load over the specified value, especially when the temperature is high, may generate a reverse voltage to the cathode foil higher than the natural dielectric strength, and may form up the oxide on the cathode foil.

However, oxide and sulfate are not water soluble and do not enter the blood stream while orotate and glycerate have normal exiguous liver conversion.

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, in the context of legal and civic policy, these controversies are less than novel.

However, despite the insight of many of his observations, his own conclusions are open to suspicion because of his failure to employ at all times the correct research methods.

However, there are still several types of calls that necessitate the use of telephone operators.

However, he states unequivocally `` the scandals in business are far less significant than the scandals in labor ''.

However, few are taxed, and the owners and location of most boats are unknown to the assessors on the date of assessment of town valuations.

However, the surface temperature gradient can produce erroneous vapor-pressure measurements for the bulk liquid helium unless precautions are taken to isolate the tube ( which passes through the surface to the vapor pressure bulb ) from the liquid helium surface.

However, if their United States income is not subject to the withholding of tax on wages, their returns are due June 15, 1962, if they use a calendar year, or the 15th day of the 6th month after the close of their fiscal year.

However, the aircraft which we have today are tied to large, `` soft '' airfields.

However, some formulas are used more than others.

However, there is also much to be gained by making use of the abilities of the local people who are available and interested in recreation.

However, there are photographs of suspended drops of cyclohexanol phthalate ( viscosity 155 poises ) suspended in corn syrup of 71 poises in a paper by Mason and Bartok.

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, as so many of the records are not certainly based on newborn snakes, these data must be taken tentatively ; ;

However, if these procedures are applied more often, conditioned emotional responses are temporarily abolished.

However, it cannot be presumed, informal though the structure of the population seems, that there are not well-defined roles within the system.

However, the differences in procedure are fundamental.

However, the regionally differentiated results, which appear below in tables, are interesting evidence of the problems of developing self-government under even the most favorable circumstances.

However, if Federal funds are used, it would be entirely appropriate to train workers for jobs which could be obtained elsewhere as well as for jobs in the area of chronic unemployment.

However, it is not known to either the union or the public precisely how much of a cost increase is caused by a given change in the basic wage rate, although the companies are presumed to have reliable estimates of this magnitude.

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, modesty and triviality are different qualities.

`` However, evidence that the Axis powers are making significant preparations indicative of such an intention is being reported with increasing frequency from a variety of sources.
