The effect on the interfacial gravity wave between two fluids is studied when there is a temperature gradient in the fluids. It is found that the thermal effect is closely related to the phase transformation across the interface. The interfacial conditions with mass flow are first derived. Then the dispersion relation…
Summary The adsorption of silicate and phosphate from pure and mixed solutions by four soils known to fix phosphate strongly has been measured. The adsorption at constant pH for each acid from its pure solution follows the Langmuir isotherm. The maximum adsorption of silicate by three of the soils from the pure soluti…
The scattering of x rays from noncrystalline samples of BeF2 and SiO2 at 25°C has been measured and analyzed. The diffraction patterns, typical of the atomic arrangement found in liquids, show interference to values of the scattering variable s=16 and beyond. The glasses contain BeF4 (SiO4) tetrahedra joined at the co…
Dielectric specimens in the shape of a frustum of a cone were evaluated for surface flashover strength in vacuum of 10-5 torr. Data were obtained for positive and negative pulses of several hundred kilovolts amplitude and with rise times in the nanosecond and microsecond region. The results indicate that most material…

Abstract Calcite phases with different amounts of ferrous iron (determined by microprobe analysis) are distinguishable by study of stained thin sections and stained acetate peels. We have defined four such phases, they are (a) non-ferroan calcite (0.0% FeO; red stain), (h) ferroan calcite I (0.5% to 1.5% FeO; red-purp…

An analysis of infrared conversion to visible and ultraviolet radiation by Yb3+–Er3+, Yb3+–Ho3+, and Yb3+–Tm3+ ions in crystals is presented. The expression for the visible power output in the presence of back transfer from the active ion to the energy-transferring ion (Yb3+) is given and the relationship between the…
