Our review will address two main questions: the passage of ionizing particles through matter, of which the passage of particles through a photographic layer is a special case, and the nature of the processes in the photographic layer that ultimately lead to its development. The second question, bein…
Attempts to influence the lifetime of radioactive substances were undertaken for more than 30 years after the discovery of radioactivity. The effects of temperature, pressure, concentration, age, external fields, chemical state, and the external environment on the decay rate were investigated. Howev…
Several simple models of the structure of the atomic nucleus have been proposed to date. The most important among them are the liquid-drop model and the nucleon shell model. Each of these simple models satisfactorily explains certain nuclear phenomena, but none can explain the entire set of known pr…
The purpose of the present review is to present all the material as elementarily as possible and to make it accessible to a broader circle of theoretical physicists. Unfortunately, the method set forth here, which in the case of a planar lattice solves the problem completely, does not generalize dir…
Let us consider spinless scattering, i.e., the case in which the interaction of particles does not depend on the orientation of their spin and orbital angular momenta. In the case of nuclear forces, for which spin interactions are very large, this is in fact realized only for particles with zero spi…
A report delivered in November 1951 at the Faculte des Sciences de Paris.
This paper examines when closely spaced steeply dipping coal seams in a suite should or can be mined in ascending order, drawing on cases from mines of the Kaganovichugol trust and comparisons with other Soviet coal basins. It classifies relevant factors into conditions that make ascending extractio…
This paper addresses the determination of a rational design service life for a level in an operating coal mine when opening a lower horizon, especially where industrial reserves may be revised beyond the assumptions of the original technical design. It develops an analytical cost minimization approa…
The paper examines the calculation of reduced throw and loosening blasting charges in mining, arguing that existing formulas inadequately explain why specific explosive consumption changes with charge depth and rock properties. It develops an alternative theoretical basis by separating useful and us…
This paper examines prevention of endogenous underground fires during the mining of thick, steeply dipping coal seams in the Southern Kuzbass, using materials from the Prokopyevsk and Kiselevsk mines. It analyzes the causes of spontaneous combustion, including coal accumulations, air inflow, and hea…
The paper develops a method for constructing compact circular nomograms as an alternative to large linear slide rule type instruments for formulas with several variables. It explains how fixed and movable circular scales can perform addition, subtraction, multiplication, and division through uniform…
This paper addresses inconsistent terminology in mine ventilation literature and proposes a unified basis for distinguishing ventilation, ventilation method, ventilation layout, and ventilation system. Using definitions from mining ventilation theory, general language usage, and the Bernoulli equati…
This paper examines how to determine rational level heights in steeply dipping ore and coal deposits whose strike dimensions limit mine-field layout. It distinguishes between minimum level height, needed to maintain continuity of extraction while preparing new levels, and optimal level height, defin…
This paper examines dielectric losses in alkali halide crystals at high frequency in relation to their ionic structure and thermochemical properties. Using measurements of the loss tangent at 10^6 cycles for selected crystals and comparing them with tabulated activation energies, lattice energies, l…
This paper proposes a systematic methodology for creating series of standard setups for turret lathes and, more cautiously, automatic turret lathes in small-batch instrument and machine-building production. It argues that setup time is reduced most effectively by unifying auxiliary tooling and arran…
The paper develops an approximate method for calculating beams and plates on elastic foundations, intended to stand between the Winkler subgrade reaction model and the elastic half-space model. It proposes a two-parameter foundation model in which soil reaction is represented by forces distributed o…
This paper examines methods for determining striker energy in mining impact machines such as pick hammers, drilling hammers, and electro-pneumatic rock drills. It reviews common work-meter approaches based on plastic or elastic deformation and discusses their limitations, especially the dependence o…
This paper develops a methodology for processing experimental diagrams of electropneumatic hammers with free striker motion, focusing on cases where pressure calibration is uncertain or must be checked. Using striker and piston displacement records, pressure traces, impulse relations, and the coeffi…
This paper examines how sharp protrusions and other electrode surface irregularities affect discharge voltage in air, challenging earlier claims that small points on high-voltage electrodes may be practically harmless. Using sphere and plane electrode arrangements with wire protrusions of varied len…
This article presents a graphical-analytical method for determining the electrical parameters of direct-current and alternating-current rail circuits from open-circuit and short-circuit measurements. It reformulates standard calculations for rail and ballast specific resistance, and for alternating-…
This paper examines the selection of an equalizing reactor for two ignitrons connected in parallel, focusing on the case where one ignitron fails to fire during capacitor discharge into an inductive load. It derives relations between the reactor winding inductance, the discharge circuit inductance, …
This paper proposes a voltmeter-based method for measuring voltage distribution across solid dielectrics and insulating structures while correcting for distortion introduced by the measuring circuit. The method uses two measurements from opposite electrodes and derives the true voltage at a point th…
This paper examines whether the electrical strength of dielectric crystals is related to mechanical properties, in contrast to earlier results suggesting that plastic deformation and mechanical stress do not directly determine breakdown strength. Using published data for alkali halide crystals and s…
This paper examines possible relationships between the dielectric strength of solid dielectrics and thermodynamic or elastic properties of their crystal lattices. Using tabulated data for alkali halide salts, it compares dielectric strength with standard entropy and finds a clear inverse trend among…
This paper develops an analytical procedure for calculating the starting parameters of wound-rotor induction motors under automatic current-dependent starting control. Starting from the motor mechanical characteristic, it derives formulas for switching slip, added rotor resistance, and resistance-st…
This paper develops a calculation method for an automatic field suppression resistor whose resistance increases during de-excitation through self-heating. It formulates the transient process in an inductive field circuit using equations for electrical equilibrium, thermal balance, and temperature-de…
This paper examines a self-excited inverter circuit for converting direct current into single-phase alternating current of variable frequency, motivated by the need for economical speed control of squirrel-cage induction motors and for high-frequency power supplies. It compares the proposed choke-ba…
This paper analyzes transient processes and nonlinear oscillations in a system consisting of a series-wound generator feeding a separately excited motor. It classifies possible steady and transient regimes under changes in shaft load, derives differential equations for current and speed, and examine…
This paper examines self-oscillations in an electromechanical system consisting of a series-excited generator and a separately excited motor, a configuration treated as representative of several oscillation-prone generator, motor, and electric-machine amplifier systems. It criticizes earlier linear …
