Report providing information about the ongoing city planning for Dallas, Texas that started with the Kessler Plan in 1911. This report is broken up into four sections: "Railroad Transportation; Air Transportation; Highway Transportation; Water Transportation," and discusses the existing conditions of each, and proposed plans to improve the transportation system. Also included are maps and a table showing transportation facilities and the "[v]olume and Direction of Passenger and Freight Train Movements - Average Normal Day."

Abstract: Procedures are presented in detail of two methods for the determination of very small percentages of uranium (down to 0.002%). The methods are applicable to a wide variety of materials. Notes on the methods and confirmatory experiments are also given.

A report about commercial production of rugged portable radioactivity detectors. The objective in all cases is to use the fastest and most productive method of detecting radioactive deposits in a given area.

This report analyzes a procedure based on the production of acetylene from the active water, with subsequent measurement of the ionization caused by the tritium beta particle. This eliminates the troublesome absorption on the chamber walls when hydrogen is used, and provides a rapid method for the preparation of the urine samples.

The following report covers investigations on the application of the beta counter as an analytical tool for use in experiments on the extraction and concentration of uranium from low-grade (.005-.02 % uranium) shale and phosphate rock ores.

From introduction: "The discovery of element number 96, curium, was realized by the preparation and identification of the isotope Cm-242 by G. T. Seaborg, R. A. James and A. Ghiorso by cyclotron bombardment of Pu-239 with helium ions."

Abstract: "Preliminary studies are reported on the use of the ion exchange resins for the adsorptions of purines, uracil, nucleotides, kynurenic acid, and coproporphyrin. Adenine and guanine are adsorbed on IR-100 resin from neutral solution and eluted by HCl. Kynurenic acid and coproporphyrin are adsorbed from neutral solution on IR-4 resin and eluted by HCl. Coproporphyrin is strongly adsorbed on IR-100 resin from either acid, alkaline, or neutral solution. Kynurenic acid is poorly adsorbed on IR-100 resin from neutral aqueous solution. The preliminary application of these procedures to the spectro-photometric study of urine is described."

The following document describes some studies of the radioactive isotopes of cerium and lanthanum lying on the light or neutron-deficient side of stability.

The following report records the study of albino rats subjected to beta rays and analyzes the skin reactions and metabolic patterns.

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 report is divided into two parts, both parts center around the effects of radiation on skin tissue. Part one focuses on superficial radiation, or Beta rays, while part two is on penetrating radiation, or neutrons and gamma rays.

This report discusses the contributions of the workers at Tennessee Eastman Corporation in the investigation of limiting conditions in the application of penta-ether (aka. dibutoxytetraethylene).

Introduction: "The purpose of this work was to develop a high-frequency pulse generator that could be used in conducting research on high-rate trigger pairs and scaler circuits. The need for an instrument of this type arose because there was no parallel commercial instrument having this type arose because there was no parallel commercial instrument having a pulse recurrence frequency over approximately 200,000 pulses per second."

Abstract: "This is a compilation of the material in several reports on the extraction of uranium from aqueous solutions with dibutyl carbitol. Data is presented concerning the optimum conditions for the extraction of the uranium and elimination of impurities."

Abstract: "This is a compilation of the data on uranium peroxide precipitations appearing in several reports. The solubility product is measured. The effect of many individual ions on the hydrogen peroxide decomposition rate and the complexing of uranium is demonstrated. Studies on plant and other highly contaminated solutions are not included."

"This report is concerned with the effectiveness of this washback procedure in reducing the phosphate concentration and also with other methods by which the simultaneous extraction of phosphate along with tuballoy may be minimized."
