Abstract The temperature dependence of 35 Cl NQR frequencies of [(CH 3 ) 2 NH 2 ] 2 SnCl 6 was precisely determined between 78 and ca. 250 K. by means of an FT NQR spectrometer. The high‐frequency line of the two 35 Cl NQR signals having the intensity ratio of 2:1 already reported was observed to be split below 102 K.…

Several 13.2 kV, 21,000 HP synchronous motors failed as a result of interturn insulation breakdown. Investigation of motor failures indicated that the cause was related to high magnitude, steep fronted surge waves (References 1 and 2). Partial discharge (corona) related failures were discounted without any actual meas…

The pressure dependence of the Raman-active vibrational modes in ${\mathrm{TlReO}}_{4}$ has been investigated up to 16 GPa, using the diamond-anvil cell. The abrupt changes in the Raman spectra indicate that three pressure-induced phase transitions occur at 0.5, 1.9, and 9.7 GPa. The first two transitions are not acco…

Abstract An experimental study of agglomeration tendency and the compounding of calcium carbonates of varying particle size into polypropylene and polystyrene melts in an internal mixer and in a two roll mill is described. The tendency of particles to agglomerate was studied using the sedimentation volume method. Aggl…

It is imperative that operating personnel and regulatory agencies have secure, advance, and accurate knowledge of the true surface properties of materials to be contacted with flowing blood. The actual devices must be characterized in their sterile, immediate pre-exposure states. Although very sensitive electronic ins…

The amplification of light signals by the mechanism of stimulated Raman scattering is discussed, with specific reference to certain heavy-metal germanate and arsenate glasses with Raman-gain-coefficients G of up to 20 times that of fused silica. Calculations are presented of the intrinsic scattering losses from Raylei…

Proteins may be rigid or flexible to various degrees as required for optimum function. Flexibility at the level of amino acid side-chains occurs universally and is important for binding and catalysis. Flexibility of large parts of a protein which rearrange or move are particularly interesting and will be discussed her…

Abstract The effect of varying interaction parameters on the phase diagrams of ternary polymer blends was explored by simulating spinodals through use of the Flory‐Huggins lattice theory. Results indicate that miscibility is favored for the case of ternary mixtures of marginally miscible or marginally immiscible pairs…

Abstract The crystal structures of oxidized and photoreduced decatungstates are compared. Three specimens of decatungstate complexes were prepared in mixed solvents of H2O–CH3CN and were characterized by X-ray diffraction. Unit cell parameters are as follows: (C6H16N)4[W10O32]·2CH3CN; DECA Mr=2841.4, monoclinic, P21⁄n…

A model for protein adsorption kinetics has been presented. This model includes diffusion-limited adsorption, adsorption and desorption rate constants kon and koff, which are dependent on the surface concentration, and an interaction term for the mutual influence of the adsorbed protein molecules. It has been shown th…

Graphite intercalation compounds are synthetic metals formed by inserting layers of atoms or molecules of a guest chemical species between the layers of carbon atoms that make up graphite. Because carbon occupies a middle position in the order of electronegativity of the elements in the periodic table, graphite welcom…
