The object of this invention is a bearing: a thrust bearing. This bearing is one in which the bearing faces is a continuous annular surface and the other an annular surface divided into shoes having the form of sectors.

A selection of Russian papers on the geochemical prospecting for ores

A brief history of the development of the atomic bomb in the United States and Germany during World War II.

The following document is a collection of investigative reports on the victims of the atomic bomb in Japan. Information covers injuries, how the victim was found, if they were protected, where they were when the bomb went off, radiation effects, and more.

This article examines the history of accelerating charged particles with new types of accelerators. It is translated from a Russian publication.

The problem of the separation or enrichment of isotopes is as old as the knowledge of the existence of isotopes of stable elements. The article focuses on the mass-dependent property of atoms continuing to be investigated in laboratories to test its usefulness for new solutions to this problem.

The author's measurement using counting tubes were performed with an X-ray beam, produced by an X-ray tube. The X-ray beam impinges on only a very small part of the counting tube. In this work the counting efficiency of counting tubes with A1-Cu- and Au-cathodes is determined for X-radiation in the range 5 Kev to 60 Kev.

Report of the capabilities of the state of New York to construct and service atomic propelled vessels and to handle the shipment of packaged radioactive materials, including used nuclear fuels.

From foreword: This report provides a review of the Soviet and U.S. technical information systems.

The report is about the geophysical year oceanographic program of the Argentine Republic.

In recent years German physicists have been making increasing use of both mass spectrographs in the stricter sense and mass spectrometers which can only measure elative isotopic abundances and use electrical methods of measurement.

Using classical concepts, the author establishes a model of a luminescence atom or molecule.

On 14 November 1949, The General Assembly of the Academy of Sciences USSR met in the academy's Conference Hall to discuss the 1950 plans of the Academy

One of the problems in the spectrographic investigation of the atomic nucleus is to increase the efficiency of the source of light used for the investigation. Using new procedures outlined in the article new elements may be detected through nuclear change.

The authors describe Praseodymium which is a rare earths metal that forms several oxides.

The information about electrolytic representation of dichloroethylene is presented in this study.

A. N. Back expressed a hypothesis about the participation of organic peroxide in the process of photosynthesis. Experimental data on this question were very few. This article provides a method of investigation to support the hypothesis.

At the base of photosynthesis of green sulfur bacteria lies an oxidation-reduction reaction of transferring hydrogen from hydrogen sulfide to carbon dioxide, accomplished with the participation of light energy. Based on experiments the author concludes that chlorophyll in the process of photosynthesis plays the role of optical sensitizer.

The discussion of the preparation and properties of thorium by Werner von Bolton have led the author to make comments regarding its preparation.

Dr. H. Karsten responds to a critical review of an earlier article on Thorium originally written by Dr. von Bolton and reviewed by Mr. R. J. Meyer.

The paper represents an effort to make a quantitative determination of actinium by the emanation method in a continuous current of air.

Adsorption passivation of metals is discussed in this paper.

This study has shown the possibility of applying the adsorption method to the separation of krypton and xenon from a concentrate

The theory of metallic diffusion should be facilitated if the regularity of the lattice is disturbed mechanically, or by means of an alletropic transformation.
