The time-dependent diffusion equation is solved using transformation calculus to obtain the solute concentration in a solvent after a segregating liquid-solid interface is passed through the material. The results are presented in graphical and tabular form for typical experimental conditions and compared with previous…
The O—H bending and N—O stretching vibrations were studied in four pairs of isomeric oximes. A band at 1265 cm. −1 , characteristic of the solution spectra of the α oximes, is identified with the O—H bending mode. Tentative assignments for the N—O stretching vibration both in solid and solution spectra are advanced. T…

Abstract Die Phasenverhältnisse der Ceroxyde zwischen CeO 2 und Ce 2 O 3 und der Praseodymoxyde zwischen PrO 2 und Pr 2 O 3 werden durch Röntgenuntersuchungen bestimmt. Beide Oxydsysteme erweisen sich in der Zahl der beobachteten drei Phasen als völlig übereinstimmend und hinsichtlich der Ausdehnung dieser Phasen als…

ABSTRACT Analyses have been made of the inorganic constituents of the blood of Mytilus edulis and Anodonta cygnea. Mytilus blood resembles sea water in total concentration and composition, but has greater concentrations of calcium, potassium and total carbon dioxide. Anodonta blood has a very low total concentration o…
Samples have been cut from single crystals of the nickel-iron ferrite (NiO)0.75(FeO0.25Fe2O3in such a way that they contain one and only one movable ferromagnetic domain wall. The viscous damping coefficient for this wall, which is a measure of the losses associated with domain wall motion in this material, has been m…

Measurements of the coefficient of restitution have been made for the impact of steel balls on plates of glass and plastics. The times of contact have also been measured. The coefficient of restitution is found to be a function of the size of the specimen as well as of its elastic and anelastic properties. The variati…
Since the conventional elastic analysis of thermal stress problems coupled with limiting creep rates and time-dependent fracture stresses as (inelastic) design criteria, results in design procedures for thermal stresses (in heat exchangers, nuclear reactors, flight structures at supersonic speeds, etc.) of considerabl…
