Resolution of the products of the reactions of DPN and ATP with ultraviolet light by techniques of partition paper chromatography is reported in this paper.

Abstract: "This final report discusses the project objectives and the manner in which these were attained in connection with the design and manufacture of the Austin Beta-Gamma Hand and Foot checker (Fig 1). Improvements incorporated to conform the equipment to modern production methods, as well as practical changes to achieve automatic operation and increased stability and to facilitate and simplify maintenance procedures, are covered in detail. The report also includes photographs (Figs. 2 and 3) and a schematic diagram of the final product (Fig. 4)" (p. 1)

From introduction: "Discussion of alternate processes for manufacture of perfluoroxylene as insurance against any eventuality, e.g. disaster, poor quality, required amount of elemental fluorine not obtainable, necessity for further expansion at some future date, or decreasing cost."

Development of certain liquid and solid fluorocarbon compounds with special properties.

From foreword: "Construction of some typical ionization detectors and their operation, with most developed at the Los Alamos Laboratory and a few at other projects connected with the development of the atomic bomb." This report includes chapters 8-16 and an appendix to the second part.

Results of an investigation carried on for the following purposes: (1) To determine the relative life of filaments when operated at low emission (low temperatures) as compared to those operated at high emission values. (2) To determine the nature of the dependence of life upon the initial diameter of the filament. (3) To determine the effect of varying concentrations of water vapor and air upon the life of the filaments. (4) To determine the relative life characteristics of tantalum as compared to tungsten.
