Survey of the Present Status of Isotope Separation Methods
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 Counting Efficiency of Counter Tubes with Aluminum, Copper and Gold Cathodes for X-Rays in the Range 5 Kev to 60 Kev
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.

About the Model of Bacterial Photosynthesis
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 Activation of the Rare Earths by Thermal Neutrons
The present knowledge of artificial radio-activity is more spotty for the rare earths than for any other region of the periodic table. The chief reason for this is the difficulty of obtaining sufficiently pure samples or at any rate such of well-known composition. Rare earthers were investigated through the activation by thermal neutrons.
