This study examines physicochemical interactions in binary liquid systems of methyl alcohol with isovaleric acid and with acetic acid. Electrical conductivity, density, and viscosity were measured at 0, 25, and 45 °C, and composition dependent curves, temperature coefficients, and viscosity correcte…

This study examines chemical interaction in binary liquid systems of formic acid with pyridine and with aniline, comparing their behavior with previously studied acetic acid systems. Electrical conductivity, viscosity, and density were measured over selected temperatures, and the formic acid, anilin…

This paper examines gas flame combustion in free turbulent jets, arguing that purely hydrodynamic theories of cold turbulent jets cannot adequately describe burning flames because they omit chemical kinetic parameters. Using experiments on water gas issuing from burners of varied diameters, velociti…

This paper examines how the electric strength of dielectric materials is related to dielectric permittivity, focusing on alkali halide crystals. It compares theoretical expressions linking breakdown strength to total permittivity and to field-induced mechanical stresses with experimental dependencie…

This paper examines the relation between dielectric strength and crystal lattice constant in alkali halide dielectrics, using experimental data and comparisons with earlier theoretical arguments on ionic radius, ionization potential, and lattice bonding. For simple alkali halide crystals, the dielec…

This paper examines the relation between the electric strength of dielectrics and the binding energy of their most weakly trapped electrons. Using experimental data for alkali halide crystals, color centers, sulfur, MgO, and related materials, the authors compare breakdown field strengths with optic…

This paper examines the relation between dielectric polarizability and electron excitation energies in alkali halide crystals. Using tabulated static and optical dielectric constants together with ultraviolet intrinsic absorption edges and energies for electron release from F centers, it compares th…

This paper reassesses the stratigraphy of Lower Cambrian deposits in the Western Sayan, focusing on the position of the West Sayan Formation, its analogues, and associated intrusive rocks. Drawing on long-term field observations, lithological correlations, unconformities, tectonic relationships, and…

This paper examines the structural controls on preserved serpentinite weathering crust in the Kempirsai hyperbasite massif, with emphasis on ochre and nontronite formations of practical mineral significance. Using geological maps, sections, and comparisons of rose diagrams for pluton structures and …

This paper examines the origin of microrelief in the weathering crust of ultramafic rocks in the Kempirsai massif of the Southern Urals. After describing the zonal structure and Mesozoic to Cenozoic history of the crust, it argues against interpretations that identify the present microrelief with a …

This paper describes unusual cockade-like textures in pyroxene-feldspar metasomatic formations observed near the Sartygoy mine in Khakassia, where skarnification affected limestone remnants and gabbro-dioritic rocks associated with a granitic pluton. Using field relations and petrographic observatio…
V. G. KOREL
This paper examines the contact metamorphism of the Sheregesh iron ore deposit in Gornaya Shoria, focusing on its relation to syenite bodies and the younger granites of the Sarlyk massif. On the basis of mineralogical and textural observations of skarns, ores, and country rocks, it describes amphibo…

This study examines the petrographic composition, facies variability, and accumulation conditions of a coal seam in the Prokopyevsk district of the Kuzbass on the basis of 17 seam samples collected along and across strike. The analysis distinguishes lower, mainly bright and semibright coal bands fro…
V. A. KUZNETSOV
This paper reexamines the age and stratigraphic position of ultrabasic intrusions in Tuva and the Western Sayan, a question important for regional tectonics and mineral exploration. On the basis of several years of field observations, mapping of hyperbasite belts, fossil evidence from the Aktovrak F…
A. M. KUZMIN
This paper critically reexamines the mineralogical status of microcline within the alkali feldspars, focusing on its relation to orthoclase, anorthoclase, sanidine, adularia, and albite. Drawing on published crystallographic, optical, chemical, and genetic data, the author reviews earlier interpreta…

The proposed article provides a review of a number of works concerned with elucidating the molecular mechanism of bulk viscosity. The number of experimental and theoretical studies on excess Stokes absorption of ultrasonic waves is very large. We did not aim to provide an exhaustive review of these …

In recent years, much information has been accumulated concerning the static properties of nuclei. Various methods have been used to determine nuclear spins, magnetic moments, and electric quadrupole moments: optical spectroscopy, molecular and atomic beams, nuclear induction, and microwave spectros…

The present article is devoted to certain questions in the theory of adsorption. It will deal with the mechanism of so-called “activated” adsorption. We shall confine ourselves here to the qualitative aspect of the matter. Readers interested in mathematical questions should consult the original work…
