Abstract A kinetic study of the graft copolymerization of methyl methacrylate onto jute fiber using KMnO 4 –malonic acid redox initiator system has been made. Effects of the concentrations of malonic acid, monomer, and KMnO 4 on graft yield have been studied. Besides, the effects of temperature, acid, and reaction med…
The applicability of the structural unit model, developed for tilt boundaries by Sutton and Vitek (1983), to (001) twist boundaries in f.c.c. metals is investigated. The model is found to be useful in discussing the continuity of boundary structure with misorientation and the Burgers vectors of screw grain boundary di…

A model is constructed which explicitly includes the microscopic phenomena occurring in krypton adsorbed on basal graphite from submonolayer to dense-layer regimes. Second-layer adsorption is also included. The experimentally observed reentrant phase diagram, in the pressure and temperature variables, is reproduced. T…

The extent to which the photoelectronic properties of amorphous chalcogenides can be influenced by specific chemical dopants is a key issue in the study of this technologically important class of semiconductors. The elemental nature and ambipolarity of a-Se make it a particularly attractive candidate for study. The ef…

Abstract An empirical pressure–volume–temperature (PVT) equation of state is presented for polymers in the liquid state, i.e., above the melting point of a crystalline polymer or the glass transition of an amorphous polymer. In terms of reduced variables, the equation is given by \documentclass{article}\pagestyle{empt…
An experimental study of electrostatic electron lenses as a function of geometrical and electrical parameters is described. The lenses are of the symmetrical three-electrode unipotential type. The parameters are the thickness of the center electrode and the interelectrode spacing, both relative to the center electrode…
We present the sequence of full-length chicken triosephosphate isomerase (D-glyceraldehyde 3-phosphate ketol-isomerase, EC 5.3.1.1) mRNA based on the analysis of cDNA and genomic clones. To isolate cDNA clones encoding the enzyme, we screened a muscle cDNA library with radioactively labeled cDNA made from RNA that had…
A computer program to calculate the contributions of crystal, capillary and a simple model of mother liquor to the overall absorption of X-rays has been written. It is based on the Gaussian quadrature method of integration; the crystal is described by the polyhedral faces bounding it, the capillary by its diameter, th…
Abstract— The binding of hematoporphyrin derivated (Hpd) to lipid vesicles and bacterial membranes was determined by fluorescence spectroscopy. The fluorescence measurements of Hpd in aqueous solutions showed two bands at 613 and 677 nm. In lipid environments of lecithin vesicles the fluorescence spectrum was shifted…
A new lyginopterid pollen organ is described based upon specimens occurring in a single coal ball from the Providence, Kentucky locality. Seven to nine beaked sporangia are fused together at their proximal ends forming a common synangial chamber; synangia are joined together in clusters of two or three. In situ prepol…

Low-density regions developed in liquefied polyethylene with a point-plane electrode configuration under high electric fields have been investigated using a Schlieren technique in the temperature range from 120 to 200°C. This region, having a refractive index or a density lower than the surrounding medium, is always f…
The crystallization behavior of an Li 2 O‐Zn0‐SiO 2 glass with a ZnO content of −28.5 wt% and nucleated with P 2 O 5 was investigated by infrared spectroscopy, X‐ray diffraction, and scanning electron microscopy.
