However, no bio-defense solution seems to be able to compete with a simple reduction of import volumes, and its corresponding reduction in risk of any accidents.

However, the reduction of unstressed vowels to schwa ( i. e., to unpronounced vowels ), due to a fixed stress location, contributed to this process, a pattern which is common to many Germanic languages ( although a few, such as dialects of Norwegian, Icelandic, and Faroese, have not undergone this reduction of vowel sounds ).

However, the encouragement of olive production for export could actually have led to increased hardship for many Athenians since it would have led to a reduction in the amount of land dedicated to grain.

However NO < sub > 3 </ sub > is more abundant so most phytoplankton have adapted to have the enzymes necessary to undertake this reduction ( nitrate reductase ).

However, in the United Kingdom, the main competition for the broadside was the gradual reduction of the newspaper tax, beginning in the 1830s, and eventually its dismissal in 1855.

However, studies to determine its effectiveness for fever reduction, as a mosquito repellent and to prevent premature ejaculation have been inconclusive.

However, the real attraction of limited animation was the reduction in costs: because limited animation does not require as many drawings as fully keyframed animations, it is much less expensive to produce.

However, the viable counts in these cultivation studies have been small when compared to total counts, and the numerical significance of these isolates has been unclear.

However, the fact that this particular formulation assigns numerical values to levels of satisfaction is the source of criticism ( and even ridicule ).

However, the numerical sign problem makes it difficult to use lattice methods to study QCD at high density and low temperature ( e. g. nuclear matter or the interior of neutron stars ).

However he also mentioned in the same report: " Meanwhile attention is being turned to the still difficult, but less unpromising, problem of radio detection and numerical considerations on the method of detection by reflected radio waves will be submitted when required.

However, the complete theory of the Abbe sine condition shows that if a lens is corrected for coma and spherical aberration, as all good photographic objectives must be, the second principal plane becomes a portion of a sphere of radius f centered about the focal point, ..." In this sense, the traditional thin-lens definition and illustration of f-number is misleading, and defining it in terms of numerical aperture may be more meaningful.

However, there can be problems even with just using numerical averages to compare material standards of living, as opposed to, for instance, a Pareto index ( a measure of the breadth of income or wealth distribution ).

However, needing to counter the Spartans ' numerical advantage, Epaminondas implemented two tactical innovations.

However, it can include decreased oxygen-binding ability of each hemoglobin molecule due to deformity or lack in numerical development as in some other types of hemoglobin deficiency.

However, even this degree-two solution should be used with care to ensure numerical stability.

However, in all but the simplest cases, the problem of determining ahead of time when two bodies will collide ( given some initial data ) has no closed form solution — a numerical root finder is usually involved.

However, numerical tech specs were not included.

However, long MD simulations are mathematically ill-conditioned, generating cumulative errors in numerical integration that can be minimized with proper selection of algorithms and parameters, but not eliminated entirely.

However various numerical methods exist for computing approximatively the value of y corresponding to any fixed value of x ; this allows to find an explicit approximation to the implicit function.

However, controversy has surrounded the high scores achieved by the Chinese students due to the unusual spread of the numerical data, with suggestions that schools were ' gaming ' students for the exams.

However, the two densities must be converted to the same units before carrying out the numerical ratio calculation.

However, in most modern computer programs for molecular Hartree – Fock calculations this procedure is not followed due to the high numerical cost of orthogonalization and the advent of more efficient, often sparse, algorithms for solving the generalized eigenvalue problem, of which the Roothaan – Hall equations are an example.

However this form is not particularly useful for numerical inversion, and faster discrete inversion methods exist.

However, for a formally correct computer program, one would have to introduce a numerical tolerance ε and test in line whether P lies within ε of L, in which case the algorithm should stop and report " P lies very close to the boundary.

However, numerical analysis and analytical methods allow only for the calculation of the stress tensor at a certain number of discrete material points.
