Summary In the “terra firme” of the Amazon basin near Manaus, podzol soils occur carrying heath forest. The parent materials are geologically young sandy sediments deposited in valleys. There are no indications that man's activity is one of the pedogenetic factors of the podzol development. Podzols have gradational co…
The Eyring Model has been used to derive the "power rule" for capacitors. Analytical models for evaluating progressive and step stress tests are presented. Various methods are discussed for determining the value of the exponent for the power rule. In particular, the relation between the exponent of the power rule and…
Stacking-fault tetrahedra have been observed in plastically deformed specimens of copper, silver, gold and several alloys. A dislocation reaction is proposed for the formation of these defects during deformation. From the size of the largest tetrahedra, estimates of stacking-fault energy are made which indicate that t…
Abstract The scheme and treatment of the kinetics of scorch-delay vulcanization proposed in a previous paper were applied to natural rubber sulfur vulcanization accelerated by 2,2′-thiobisbenzothiazole (MBTS), 2-(N-cyclohexyl)benzothizaolesulfenamide (CBS), 2-(N-morpholinothio)benzothiazole (MOR), or 2-(N,N-diisopropy…
Pratt and Bailey have recently explained the optical and anomalous magnetic properties of Cr2O3 by means of a model consisting of the basic Cr2O3 antiferromagnetic structure with moments canted away from the c axis and forming some kind of spiral. Our neutron powder-diffraction data confirm the original Brockhouse mom…
It is argued that there is a critical cation-anion covalent mixing parameter λc such that ligand-field theory is appropriate for λ<λc, but band theory must be used for λ>λc. This provides, therefore, a criterion for distinguishing metallic vs magnetic compounds in those structures, like perovskite, where…

A gas-filled bubble in a liquid will generally dissolve because of diffusion of gas out of the bubble into the surrounding liquid. However, when set into motion by an acoustic field, a bubble may grow by a process called rectified diffusion. This process can counteract the effect of diffusion for values of the acousti…
Fluorescence yields and lifetimes of solutions of europium and terbium salts in solution are greatly enhanced by using deuterated solvents. The magnitude of increase varies from an 18-fold enhancement in yield and lifetime for an aqueous solution of europium nitrate to a twofold enhancement for europium ethylenediamin…
A review of neutron diffraction studies of the magnetic properties of rare-earth metals and alloys is presented. For each of the pure metals Tb, Dy, Ho, Er, and Tm there is observed a transition at a temperature TN to an oscillatory antiferromagnetic configuration (helical or linear oscillator type). At lower temperat…
