Abstract Extinction of the diffusion flames in the stagnation‐point flow above the commercial polymers, poly(methyl methacrylate), polyoxymethylene (two types), polyethylene (three types), and polystyrene, is studied. The extinction data are used in a theory developed to obtain overall rate parameters for gas‐phase co…

Projectilelike reaction products from the $^{209}\mathrm{Bi}$+$^{136}\mathrm{Xe}$ reaction were studied at a laboratory bombarding energy of 1422 MeV. The fragments were identified by atomic number, and their kinetic energies and angular distributions were measured using three solid-state $\ensuremath{\Delta}E\ensurem…
Abstract The title compound has been synthesized by reaction of MeSnBr 3 and NaHSe in aqueous solution. The X-ray structure determination showed adamantane-like molecules (Sn-Se 253(1), Sn-C 215(1) pm) arranged in a quasi hexagonal-close packing. The atomic coordinates were used for an analysis of the vibrational spec…
The plastic deformation of niobium single crystals, purified by ultra-high-vacuum annealing, has been investigated in tension at temperatures between 77. and 4.2 K. The strongly orientation-dependent behaviour has been demonstrated by studying two tensile axis orientations, C (χ=l°, λ = 47°) and H (χ = 30°, λ = 45°).…
Abstract Die Perowskite Ba 2 B III SbO 6 kristallisieren monoklin (B III La, Pr, Nd) bzw. kubisch (B III Sm, Eu, Gd, Tb, Dy, Yb, Lu, Y). Die Sr‐Verbindungen, Sr 2 B III SbO 6 , besitzen eine monokline (B III Nd, Sm, Eu, Dy), rhombische (B III Yb, Lu, Y, Sc) bzw. kubische (B III In, Ga) Perowskitstruktur. Mit…
Abstract In a model reaction of terephthalic acid with aniline by using triphenyl phosphite in a mixed solvent of pyridine and N ‐methylpyrrolidone (NMP), mono‐ and dianilides were produced with relative yields varying with the content of pyridine in the solvent. The polycondensation of terephthalic acid with aromatic…
Abstract Based on the single, composition‐dependent glass transition criterion, poly‐ϵ‐caprolactone (PCL) was found to be miscible with each of four poly(styrene‐co‐allyl alcohol) (SAA) copolymers with hydroxyl contents between 1.3 and 7.7 wt %. Melting point depression of the PCL in the blends was used to evaluate th…
Dielectric properties of MnO at rf (up to ${10}^{5}$ Hz) along a [111] direction have been measured for the temperature range of 7 to 298 K, with special attention to the region near ${T}_{N}\ensuremath{\simeq}118$ K. A significant anomaly (\ensuremath{\sim}12% drop) in ${K}^{\ensuremath{'}}$, the real part of the die…
Anodic galvanostatic charging of nickel in p H 7.65 borate buffer solution produces a finely porous oxide film which is distinctly different from the passive film of NiO . The porous film which is probably NiOOH can grow to thicknesses in excess of 1000Å. It is reduced to a lower oxidation state during galvanostatic r…
Retention times (Rt) for acrylates, methacrylates, and vinyl monomers were measured with two different columns (C18 Corasil and C8 LiChrosorb) using reverse-phase HPLC in order to obtain their partition coefficients between 1-octanol and water (log P). The log P values of test compounds were determined from the regres…
Electrophoretic and albumin immunological data indicate that the Brachyphyllinae as currently conceived is a natural assemblage, with Erophylla sezekorni and Phyllonycteris aphylla being more closely related to each other than either is to Brachyphylla cavernarum. In both data sets, values that distinguish Erophylla f…
The birefringence in mixtures of 4-cyano-4\ensuremath{'}-octyloxybiphenyl (80CB) and 4-cyano-4\ensuremath{'}-hexyloxybiphenyl (60CB) has been studied near the nematic---to---smectic-$A$ ($\mathrm{NA}$) and smectic-$A$---to---reentrant-nematic ($A{N}^{\ensuremath{'}}$) transitions. There is an overall increase in the b…
Repeated attempts have been made to develop a corrosion index that would be applicable to all waters. These attempts have made it clear that a series of indexes must be employed to take into account the many different types of corrosion as well as all mitigating parameters.
It was shown that a modified Huey test, i.e., a 24-h immersion in boiling 40% HNO3, is able to exactly detect the susceptibility to intergranular corrosion of Alloy 600, which is correlated with intergranular stress corrosion cracking (IGSCC) behavior in high temperature water containing small amounts of chloride ions…
Forty-two patients who had bursts of spontaneous, bilaterally synchronous slow waves during the waking state in an otherwise normal EEG were compared with 42 age-matched control subjects with normal EEGs. The study group had a significantly higher incidence of diffuse encephalopathy than did the control group. They al…

To investigate mechanisms of reactive hyperemia, single arterioles of the hamster cheek pouch were occluded for periods of 1 s-3 min. Arteriolar diameters were measured upstream and downstream from the occlusion. O2 availability to the tissue was controlled by equilibrating the suffusate with low (0% O2) or high (10%…
The x-ray diffraction pattern from aligned samples of the smectic-$I$ ($\mathrm{Sm}I$) phases of a number of compounds has been considered, with particular emphasis on TBDA (${\mathrm{C}}_{10}$${\mathrm{H}}_{21}$ PhNCHPhCHNPh${\mathrm{C}}_{10}$${\mathrm{H}}_{21}$, where Ph stands for the phenyl group) which exhibits b…
