Measurements of the effects of stress on the initial magnetization curve of a sample of 1 % Mn pipe line steel and on its reversible component are presented. Stress-induced changes in the reversible and irreversible magnetization components are shown. Examples of magnetization changes induced by tensile and compressiv…

A differential scanning calorimeter (DSC) investigation (heating rate 10 K/min) is presented on the multiple transition (relaxation) spectra of PMMA: Tβ < Tg; Tg, Tll > Tg; and Tlρ > Tll, as a function of tacticity. Specimens are characterized by fractional triad content: isotactic (it-), Xii; syndiotactic (st-), Xss;…
The efficiencies of a solid absorption heat pump are calculated with the help of chemical models. The first one is based on a reversible analysis where only the energy contributions to regenerate and insure continuous operations of the engine are taken into account. In the second one, the complete thermochemical behav…

Measurements of thermodynamic compatibility, technological properties, stress-strain isotherms at high elongation, birefringence, and wide-angle x-ray diffraction have been made on blends of guayule rubber (cis-1,4-polyisoprene) and trans-polyisoprene (t-PI). Both cross-linked and un-cross-linked systems, prepared by…
Polypropylene containing the blowing agent azodicarbonate was first grafted with vinyl trimethoxy silane, then crosslinked using the hot water treatment. Two heating stages initiated the blowing agent and formed polypropylene structural foam. The effects of such reaction variables as initiator, cross-linking agent, cr…
Abstract Mineralogical analysis of Devonian Red Marl using XRD, TEM, SEM and EDAX showed that it consisted of illite, quartz, and feldspar with minor amounts of chlorite and hematite. Physico-chemical changes in the soil minerals on reaction with lime (calcium hydroxide) from one day up to two years were investigated…
The reduction of proline by Clostridium sporogenes NCIB8053 is coupled to transmembrane proton translocation in an uncoupler-sensitive fashion (and might therefore conserve free energy). This finding serves to explain the increase in the growth yield of this organism when proline is added to a defined growth medium co…
Heat treatment of polyester yarns induces the selective crystallization of the cyclic trimer [(GT)3] in the form of polygonal solids on the fiber surfaces. At the temperature studied, namely, 200°C, the diffusion rate of (GT)3 appears to be very rapid. Small quantities of the cyclic tetramer were also found. The total…

Two independent state-of-the-art equations for incipient hydroplaning speeds, which were regressed from experimental data for different ranges of magnitudes of water film thicknesses, are investigated relative to merging them into a single criterion. One equation was developed for water film thicknesses above 0.10 in.…
Polymer surfaces have been modified by chemical reaction or thin film deposition using a capacitatively coupled plasma RF-discharge system. This has allowed the production of a graded, reproducible series of surfaces with surface energies ranging from low to high. Three gases, hexafluoroethane (C2F6), perfluoropropane…

Using the Landau expansion simple formulas are found that allow for systematic calculations of the tricritical temperature for a given molecular model. The theory is applied to some molecular models of the nematic–smectic A (NA) phase transition of liquid crystals. It is shown exactly that for a large class of molecul…
