Abstract The sorption and transport of CO 2 in miscible PVF 2 /PMMA blends are reported at 35°C as a function of pressure from 1 to 25 atm. Significant plasticization by CO 2 is evident for all blend compositions. This effect induced further crystallization of PVF 2 for some blends, altered the shape of sorption isoth…
In a previous study, we reported the apparent similarity between a low resolution electron density map of mitochondrial malate dehydrogenase and a model of cytoplasmic malate dehydrogenase (Roderick, S. L., and Banaszak, L. J. (1983) J. Biol. Chem. 258, 11636-11642). We have since determined the polypeptide chain conf…
A simple model of hopping transport in a molecularly doped polymer is described based on a small electric-field perturbation of diffusional (random walk) electron self-exchange reactions in the solid state. A master expression is derived which quantitatively accounts for the electrical field, temperature and concentra…

A Bacillus subtilis 2.7-kilobase DNA fragment containing an intracellular protease gene was cloned into Escherichia coli. The transformants produced an intracellular protease of approximately 35,000 Mr whose activity was inhibited by both phenylmethylsulfonyl fluoride and EDTA. Introduction of the fragment on a multic…
Many alkyl derivatives of carbohydrates are used as detergents for cell wall membranes. This study describes the liquid-crystalline properties of a number of these systems. The combination of a hydrophilic carbohydrate moiety and a hydrophobic aliphatic substituent leads to the formation of both thermotropic and lyotr…

The structure of bovine intestinal calcium-binding protein (ICaBP) has been determined crystallographically at a resolution of 2.3 A and refined by a least squares technique to an R factor of 17.8%. The refined structure includes all 600 non-hydrogen protein atoms, two bound calcium ions, and solvent consisting of one…
Since Thewlis found the "two fiber axes" patterns on x-ray diffractograms of human enamel in 1934, many investigators have studied this problem. However, a definite answer has not yet been obtained. The present detailed x-ray diffraction study showed that the "two fiber axes" patterns in human enamel were caused by re…
Abstract It has been seen from the above survey that a few of the treadwear predictor correlations have the required accuracy to provide a satisfactory alternative to road testing of tires for the wear performance of carbon blacks, depending on requirements and circumstances. Correlations based on laboratory rubber te…

Experiments performed with a current industrial-texturing nozzle on a specially designed singlehead texturing machine are described. These involve the use of high-speed still and cine photography, together with measurements of yarn speed on emergence from the nozzle and yarn-tension measurements at various stages of t…
The growth of crystalline anodic aluminum oxide during anodization in an aqueous ammonium citrate electrolyte has been investigated. Crystalline sites were observed to nucleate only during the early growth of the oxide film, and their number was dependent upon the electrolyte temperature and the crystallographic orien…

Spectroscopic photoresponse of the passive film formed on iron in neutral borate solution was studied. The spectroscopic three parameter reflectometry and the photoelectrochemical technique were employed to obtain the spectra of absorption coefficient and photocurrent. From these spectra, a conversion efficiency, η, f…
