Lowest-Order Contribution to the Lattice Thermal Conductivity
In a previous paper the correlation function formula for the thermal conductivity was used to derive equations for the lowest-order contribution to the lattice thermal conductivity Kij. An explicit but formal solution of these equations is obtained here, and it is shown how this solution simplifies in the limit of inf…
Dynamical Dislocation Theory of Crystal Plasticity. II. Easy Glide and Strain Hardening
Mathematical descriptions of the stress-strain-time behavior of plastic crystals are developed using a statistical approach to dislocation dynamics. First, the ``easy-glide'' portions of stress-strain curves are described in terms of glide band propagation. Then, three models of strain hardening are developed and used…
Transmittance of Optical Materials at High Temperatures in the 1-μ to 12-μ Range
Transmittance measurements of optical materials were made at 25°C, 100°C, 200°C, 300°C, and 400°C in the 1-μ to 12-μ range with a Perkin-Elmer Model 21 spectrophotometer. A continuous proportioning temperature control system, using a modified Loyola LC-2 4KVA Power Manipulator in conjunction with a Wheelco Capacitrol,…
The breakdown of the air-formed oxide film on iron upon immersion in solutions of pH 6–13
The breakdownof the air-formed oxide film on iron is greater upon immersion in corrosive than inhibitive solutions; it is retarded by dissolved oxygen and in some solutions marginally affected by the age, or thickness,of the film. The breakdown is not due to direct solution, as with aluminium, but to reductive dissolu…
Pressure Dependence of the Dielectric Constant of Strontium Titanate
The effect of pressure, up to 50 kbar, on the low-frequency dielectric constant $\ensuremath{\epsilon}$ of SrTi${\mathrm{O}}_{3}$ has been measured at 25\ifmmode^\circ\else\textdegree\fi{}C. $\ensuremath{\epsilon}$ decreases with increasing pressure according to the relation $\ensuremath{\epsilon}=\frac{{C}^{*}}{(p\en…
Die Absorption der Röntgenstrahlen im Dreistrahlfall der Interferenz
Article Die Absorption der Röntgenstrahlen im Dreistrahlfall der Interferenz was published on November 1, 1965 in the journal Zeitschrift für Kristallographie - Crystalline Materials (volume 121, issue 1-6).

Oxygen Stoichiometry in the Barium Ferrates; Its Effect on Magnetization and Resistivity
The barium ferrates comprise a series of compositions exhibiting a wide range of oxygen deficiency. Members of this series are isostructural with the high-temperature polymorph of barium titanate which is hexagonal with space group C63/mmc. Polycrystalline specimens with varying oxygen contents, i.e., Fe4+ concentrati…

Petch Relation in Single‐Phase Oxide Ceramics
Detailed examination of recent strength‐grain size data for MgO, Al 2 O 3 , and BeO ceramics showed that for large grain sizes behavior was of the form of the Knudsen equation: image . For small grain sizes, behavior fitted the form of the Petch equation, image or appeared similar but with negative slope. Three charac…
X-Ray-Emission Microanalysis of Rock-Forming Minerals I. Experimental Techniques
In order to provide a basis for calibration of X-ray-emission analyses, existing theories and experimental measurements on the generation, absorption, and fluorescence of X-rays produced by electron bombardment of mixed targets are reviewed and compared with new measurements for a variety of targets, principally commo…
Poly(ethylene terephthalate). I. Study of crystallization kinetics
Cast amorphous one mil films of poly(ethylene terephthalate)were allowed to crystallize isothermally in silicone oil over the temperature range 25–240°C. The crystallization paths were followed by recording the percent of transmission of 4000 A. light through the films as a function of time at specific temperatures. A…

The Influence of Temperature and pH Value on the Macro-molecular Composition of Magnesium-limited and Glycerol-limited Aerobacter aerogenes Growing in a Chemostat
SUMMARY Progressive alteration of the incubation temperature of Aerobacter aerogenes cultures, growing in a chemostat at a fixed dilution rate, caused a progressive change in bacterial concentration and in bacterial RNA, carbohydrate and protein contents; the DNA content did not vary significantly. The change in bacte…
Monovacancy formation energy and debye temperature of close-packed metals
A useful and significant relationship exists between the Debye temperature θD and the monovacancy formation energy E f. It appears that E f for close-packed metals can be calculated from θD with an uncertainty of not more than 5–10%.
Theory of Low-Energy-Electron Scattering by Polar Molecules
The diffusion cross section for electrons in a gas of polar molecules is calculated. The improvement over a previous calculation is the use of the exact scattering cross section of a charged particle by a point dipole rather than the first Born approximation. For ${\mathrm{H}}_{2}$O the correction amounts to about 20%…
Temperature and Bias Characteristics of Pb(Zr-Ti)O3 Families Ceramics
Temperature and bias characteristics of ceramics of Pb(Zr-Ti)O 3 and its families have been measured. Bias dependence can be understood with a schematic model on the reorientations of 180° and 90° domains. Dielectric and elastic anisotropies of the single crystal are expected to be larger in the rhombohedral phase tha…
Dynamical Dislocation Theory of Crystal Plasticity. I. The Yield Stress
The derivation is outlined of a general relation connecting the macroscopic plastic strain rate with the configuration and velocity distribution of dislocations in a monocrystal with a single active glide system. This can be simplified for particular cases, the most simple being the case of parallel straight dislocati…
