METHODS FOR PRODUCING FAST PARTICLES

N. S. Khlebnikov
1939 SovietRxiv: ru-193901.19895

The methodology for obtaining fast particles has repeatedly received attention in the pages of this journal. However, since in recent years further major advances have been achieved in this field, quite definite trends in development have emerged, and the production of fast particles itself has acqu…

Cleat of Thick Seams in the Prokopyevsk District and Its Influence on Stoping Operations

I. A. Molchanov and A. A. Belitsky
1939 SovietRxiv: ru-193901.07785

This paper examines cleavage and fracturing in thick coal seams of the Prokopyevsk district of Kuzbass and their practical effects on stoping operations, especially face stability and coal breaking. Based on underground observations in the Koksovaya mine and mines 3 and 3-bis, the authors develop a …

Methodology for Prospecting for the Displaced Limb of a Seam under the Conditions of the Prokopyevsk District of Kuzbass

A. A. Belitsky
1939 SovietRxiv: ru-193901.07784

This paper addresses the practical problem of locating the displaced limb of coal seams after disjunctive disturbances are encountered in underground workings of the Prokopyevsk district of the Kuznetsk Basin. Drawing on mine-geological observations from the Koksovaya Mine area and on simplified min…

Geometric Method for Studying Disjunctives and Its Application to Searching for the Displaced Part of a Deposit

I. A. Molchanov
1939 SovietRxiv: ru-193901.07783

This paper addresses the geometric interpretation of disjunctive disturbances, especially the practical problem of finding the displaced continuation of a bed, seam, or vein after faulting. It argues that existing geological and mine surveying approaches inadequately distinguish the actual relative …

Some Problems of the Tectonics of the Kuznetsk Coal Basin

K. V. Radugin
1939 SovietRxiv: ru-193901.07782

This paper examines several tectonic problems in the Kuznetsk Coal Basin using field observations, stratigraphic relationships, lithologic evidence, petrography, and geomorphological indicators. It argues for distinct pre and post ostracod limestone folding phases near Mount Orlinaya, identifies evi…

Groundwater of the Barzas District of Kuzbass

P. M. Bolshakov
1939 SovietRxiv: ru-193901.07781

This article summarizes hydrogeological investigations conducted from 1932 to 1937 in the Barzas district of the Kuznetsk Basin, an area important for sapromixite coal mining and possible petroleum exploration. Using field surveys, hydrometric observations, borehole data, geological mapping, and wat…

Geotectonic Theory of the Self-Development of Earth's Matter

Acad. M. A. Usov
1939 SovietRxiv: ru-193901.07779

This paper sets out a geotectonic theory in which the evolution of the Earth’s crust is interpreted as an expression of the self-development of Earth’s matter through alternating compression and expansion. It criticizes contraction theory, Tetyaev’s expansion-based explanation of folding, and neo-Ly…

From the Editors

Unknown
1939 SovietRxiv: ru-193901.07777

This editorial note introduces the posthumous publication of M. A. Usov’s unfinished article, “The Geotectonic Theory of the Self-Development of the Earth’s Matter,” found among his papers after his death. It explains the manuscript’s condition, including its partly outline-like form, its planned se…

Academician M. A. Usov: Obituary

M. Usov
1939 SovietRxiv: ru-193901.07776

This obituary commemorates Mikhail Antonovich Usov, a Soviet geologist, educator, academician, and public figure who died suddenly in July 1939. It presents his career as centered on the development of Soviet geological science, the reform of higher technical education at Tomsk, and the training of …

GENERAL PRINCIPLES OF COLORIMETRY

M. M. Gurevich
1939 SovietRxiv: ru-193901.06937

At present there are many books and articles devoted to the exposition of the foundations of colorimetry. The methods of exposition adopted in most of them do not seem to the author entirely satisfactory. The present article is an attempt at a more systematic exposition of the subject, intended prim…

Physics of Ionic and Electronic Processes and Technology

N. Kaptsov
1939 SovietRxiv: ru-193901.06883

In physics, there is hardly any other field in which the problems of practical application are so closely intertwined with the problems of scientific research as in the field of the physics of electronic and ionic processes, or, as it is sometimes called, the field of electrical phenomena in gases a…

HEINRICH HERTZ[^1]

N. Malov
1938 SovietRxiv: ru-193801.72134

This article is a revised version of a report delivered on April 9, 1938, at a meeting of the Department of Physics of the Moscow State Pedagogical Institute dedicated to the memory of H. Hertz.
