Abstract The investigation on phase relationships and pertinent heat effects in branched alkali alkanoates was extended to lithium, sodium and potassium 2,2-dimethylpropanoates, 2-ethylbutanoates and 3,3-dimethylbutanoates. The results allow to discuss some aspects of the thermal behaviour of these salts, among which…
Research is being conducted on potentially large-scale uses of sulfur to extend or replace such construction materials as asphalt, cement, and mineral aggregates. Paving materials have been developed in which sulfur replaces up to 50% of the asphalt and which can be handled with existing mixing and paving equipment. S…
Abstract Two major vanenes of glauconite are distinguished within the Upper Cretaceous and Tertiary formations of the Castle Hill Basin. Type A is the only variety present in the Upper Cretaceous Broken River Coal Measures, is absent in the Upper Cretaceous to Eocene Iron Creek Greensand which overlies the coal measur…
A commercial process has been developed by Gulf Oil Canada to produce a novel sulfur-asphalt (SA) binder for flexible pavements by extending and replacing asphalt with up to 50 wt % elemental sulfur. The process uses a sulfur-asphalt mixer module (SAM) to finely disperse liquid sulfur into a continuous asphalt phase w…
The paper summarizes the results of neutron scattering from a weak itinerant ferromagnet MnSi (the itinerant electron system) and Invar alloys: Fe65Ni35 and Fe3Pt (the quasi-localized spin system). Well defined spin wave excitations as well as the excitations in the Stoner continuum could be detected at 5 K for MnSi i…
Abstract Second‐order Raman spectra are studied in tetragonal ZnP 2 and CdP 2 crystals. The main feature of the spectra is a strong dominance of the A 1 ‐component over the E‐ and B 2 ‐components. Whereas the former is due to overtones, the latter ones are associated with combination tones. Besides, the A 1 ‐component…
The digestion and absorption of collagen, native and artificially cross-linked, has been examined in the rat and the Gaboon viper, by feeding known quantities and measuring the hydroxy-proline content of the faeces and of the contents of the gut at different levels, and comparing with an unabsorbable marker (polyethyl…
The reactivity of skin elastin and collagen to ANS (8-anilinonaphthalene-1-sulphonate) dissolved in nonpolar (e.g. butanol) and polar (distilled water, phosphate buffer at pH 2.8 and 8.2) solvents was compared in histological sections. The elastin fibers were demonstrated to differ from collagen at the fluorescence mi…
Abstract A novel type composite catalyst in which small amounts of La2O3 and Ru are incorporated with Ni substrate supported on a granulated silica having bimodal pore structure, was found to be a very efficient hydrogenation catalyst for selective methane formation from carbon oxides. Contrary to the case of Ni, the…
Abstract Uptake of cations by plant roots growing in soil is believed to be influenced by the relative adsorption strengths of cations by soil exchange sites. The adsorption of K and Rb by four soils was investigated to determine the differences in adsorption of K and Rb which may occur and how they are affected by so…

Recent progress in NMR analysis of Fe3O4 has revealed the presence of five B site Fe3+ ions, called B-1, B-2, B-4 and B-5. From the symmetry of the NMR lines of these ions, a very new electron ordering was proposed, in which Fe3+-I ions make pairs along [11̄0] direction and Fe2+-II ions also behave in the same way. In…
Summary An X-ray and chemical examination of deweylites reveals that they are intimate mixtures of very poorly ordered trioctahedral 2:1 and 1:1 layer silicates. The 2:1 mineral exhibits no swelling in the presence of ethylene glycol or water and is best described as an extremely fine-grained and highly disordered for…
Permanent magnets made from SmCo5 exhibit negative reversible change in magnetization with increasing temperature, typically of the order of 0.04% per deg. C. between −100 and +200 C. It is desirable to improve this property by suitable substitutions. In the present study, a systematic examination of the preparation,…

Abstract A study has been made on the impact and yield properties of polycarbonates from two manufacturers as a function of strain rate, melt flow rate, notch radius, thermal history, and test temperature. The yield stress increases with the strain rate and annealing time in exactly the way predicted by a recently pro…

The pseudobinary compounds Er 6 (Fe 1-x Mn x ) 23 are ferrimagnetic with drastically changing Curie temperatures dependent upon the Fe-Mn concentration. The magnetisation against temperature curves are analysed in terms of a two-sublattice molecular field model. It is shown that the 3d-3d interaction is dominant for t…
