Report discussing a method for the stepwise calculation of the number of transfer units utilized in a given solvent extraction operation. "Use of the method results in a very appreciable saving in time of calculation with an error of 1.5% for the runs tested. The error tends to become smaller with increasing total numbers of transfer units involved."

A report discussing an experiment conducted to determine the effect of radiation on the melting point of Tempilaq, a commercially available, temperature-indicating liquid.

Report discussing the results of research conducted by the Hanford Works Analytical Research Group during the period from March 1949 to April 1949.

Technical report including multiple lectures on nuclear science and engineering, planned to survey the theories, designs, operations, and experimental facilities of the Brookhaven Nuclear Reactor.

Technical report outlining the differences in conductivity of AGOT graphite and AGHT graphite.

From introduction: This report represents an effort to assemble, relate, and evaluate available information about possible primary uranium mineralization in the state of Arizona. This is the initial step in preparation for a system ratio field study of the state.

Preface: The existence of adequate experimental equipment, in particular the two operating cyclotrons of the Radiation Laboratory and the large 184-inch unit under construction, together with a nucleus of trained personnel, made it inevitable that work in connection with the war effort would be prosecuted vigorously at the University of California.

Partial abstract: "The investigation of the high temperature and pressure dissociation of water under irradiation was undertaken by the Power Pile Division of Oak Ridge National Laboratory in an effort to determine the degree of importance of the phenomenon with respect to the design of a high temperature water-cooled power reactor. Theory and past experimentation indicate that net steady-state dissociation is determined by the rates of the dissociation and recombination reactions under the imposed conditions, the dissociation rate being essentially a function of flux and the recombination rate essentially a function of temperature" (p. 3).

This report discusses a series of investigations for biological and biochemical study of chronic exposures of animals to neutrons through an irradiation procedure.

Abstract: "The analysis of hafnium and zirconium by the copper spark technique is presented for solutions of HCl, HF, and HClO4 acids. The special techniques of electrode protection and vacuum drying of perchloric acid samples are outlined. Also given are the working curves and deviations of both elements."

From abstract: "The means of preparing uranium trifluoride are discussed. The most practical method is the reduction of uranium tetrafluoride with uranium although reduction with hydrogen or atomic hydrogen may also be feasible...A literature survey and discussion of other means of preparation are given."

Abstract: An electronic device has been developed for indication at a distance and simultaneous automatic correction of changes in density, temperature, and interface level of polyphase solutions.

Report describing the radioactive energy output of U slugs from the Clinton pile. Outputs were measured in a calorimeter. Results have been calculated to watts per gram and compared with previous reports.

Report discussing the research done on volatile "X" compounds during the period from February 1942 to March 1943.

Report discussing experiments on the photometric determination of various elements in the presence of trace amounts of Uranium.

Report detailing the approximate calculation of the neutron flux from a plane source in an infinite medium.

Final report describing the development and usage of an automatic decade scaler which operates for a fixed number of counts, developed for use with a Geiger tube.

"Methods for calculating the opacity of materials at high temperatures are discussed in this report. Minor improvements are outlined for the treatment of continuous absorption processes, and a small error usually made in treating the scattering process is corrected. In contrast to all previous calculations of opacity, the effect of line absorption is carefully examined, for it may well be the dominant process under certain conditions of temperature and density. Detailed methods for calculating the line absorption contribution are, therefore, developed. To illustrate the principles involved, the opacity of pure iron at a temperature of 1000 volts and normal density is worked out in detail" (p. ii).

This report describes the flow meter for measuring air-flow rate through special hoods that allow the decrease in flow rate.

"The following report is meant to serve a two fold purpose. First, it is the quarterly report of the homogeneous reactor project for the Technical Division of Oak Ridge National Laboratory. Secondly, it is a description and general feasibility discussion of a 200-1000 K.W. pilot model, homogeneous reactor."

The following document presents designs and blueprints to the bubble-cap column built to replace a nitric acid concentrator.

The following report is a quarterly report by the Monsanto Chemical Company for liquid waste disposal research, covering the period between April 1 to June 30, 1949.

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.
