The increase in the electrical resistance of the specimen, associated with the α→ω transformation in Ti, has been used to obtain the fraction ζ of the ω phase as a function of time under isobaric–isothermal conditions in the pressure range 4–9 GPa and at 300±3 K. In the entire pressure range ζ–t data fit an equation o…
1. Introduction. In order to provide a continuum mechanical model for capillarity, the Dutch physicist D
The two-band transport model is expanded in order to analyze the Hall mobility of p-type III–V compound semiconductors. Using this model, the drift and the Hall mobilities can be calculated separately. The alloy scattering as an additional scattering mechanism in alloy semiconductor systems is assumed and the Hall mob…

Examination of type material showed that 8 taxa must be reduced to synonomy with Thalassiosira punctigera (Castr.) comb, nov., an extremely variable species as to size and valve structure. Preliminary experiments indicated a certain relationship between the areola size and the temperature at which clonal cultures had…
Uranium-plutonium carbide offers an improved fuel system for advanced breeder reactors. The high-thermal conductivity and density of carbide fuels permit superior breeding performance and high specific power operation. These advantages combine to increase plutonium production, reduce fuel cycle and power costs, and lo…
We investigate the coupling of the collective modes of a coexistent incommensurate charge-density-wave (CDW) superconductor (SC). We use a gauge-invariant random-phase approximation that correctly includes screening to treat both the amplitude and phase modes of the coupled system. Unlike previous work, the SC and CDW…
Abstract Wide‐angle x‐ray line broadening methods have been used to determine the crystallite size and degree of distortion for the crystalline hard domains in MDI/diol polyurethane elastomers. Crystallite widths have been determined from the integral breadths of the 00 l reflections following correction for distortio…

The temperature dependence of dielectric permittivities, shear moduli and internal friction of LiCsSO4 crystals were measured. Large anomalies were found in G1 and G2 shear moduli and in the internal friction Q-1 for the samples in a and b directions, near the Curie point Tc = 202 K. The temperature dependence of stre…
The oxygen potentials at 1,000 and 1,300°C and the lattice parameters of UO2 fuels with soluble fission product elements (Zr, Ce, Pr, Nd, Y), simulating high burnup of up to 10a,o have been measured by means of thermogravimetry and X-ray diffraction. The oxygen potentials for (U, FP)O2+x fuels are higher than pure UO2…

Computer simulation of high energy primary electron scattering and subsequent generation of ‘‘fast’’ secondary electrons in thin film targets is demonstrated with Monte Carlo techniques. A hybrid Monte Carlo model is utilized to calculate the generation and subsequent spatial trajectory of each secondary electron in t…
A sequence of edge defined techniques has been developed which allows the successive multiplication of the number of lines in a grating pattern. Holographic lithography at 351.4 nm wavelength in a liquid medium has been used as the primary pattern generation technique for producing gratings with periods of ≊160 nm. A…
