a proton nmr method for the drtermination of salvation numbers of alkaline earth cations with hexamethyl phosphoramide (hmpa) in nitromethane (nm) as diluents is described. the method is based on monitoring the resonance frequency of hmpa protons as a function of hmpa / metal ion molar ratio at constant metalion concentration. the average salvation number of cations,  , at any hmpa / metal ion ...

We derive asymptotic bounds for the ordinary generating functions of several classical arithmetic functions, including the Möbius, Liouville, and von Mangoldt functions. The estimates result from the KorobovVinogradov zero-free region for the Riemann zeta-function, and are sharper than those obtained by Abelian theorems from bounds for the summatory functions. Such functions as P μ(n)x, P φ(n)x...

Some explanation for the title of this paper is necessary. The contention is that unconventional foods are unlikely to make a significant contribution to the world food problem although they may provide sophisticated sensual enjoyment. Eating not only provides nutrients but is also fun, and both are important to man. Those of us who attempt to modify the nutrient content of human diets with a v...

Missionaries are no strangers to students and researchers of the British Empire. The hackneyed image of the rough-hewn Anglican vicar preaching salvation, Christ, and colonialism to legions of natives is one of the enduring archetypes of British colonialism. This image, like so many similar ones, is not without basis in historical fact. Missionaries played a notable role in British imperial exp...
