Abstract of Paper Presented at the Symposium on Metal ChelateChemistry at Brooklyn Polytechnic Institute on April 26, 1952

Description: The essential structural element which differentiates metal chelate compounds from metal coordination compounds, or metal complexes in general, is the existence of some linkage between two or more of the donor atoms in the first coordination sphere of the metal. It is the purpose of the present discussion to examine the influences that this structural factor may have upon the physical and chemical properties of chelate compounds. Examples of well known, simple coordination compounds involving a… more

Accumulation of Radioactivity in Columbia River Fish in the Vicinity of the Hanford Works

Description: Abstract: The data obtained from the radioassay of fish collected in vicinity of the Hanford Works between April, 1948 and June, 1950 are presented. Most of the radioactivity in the fish resulted from the concentration of p32 in the scales, bone, and certain visceral organs. The level of activity density in the fish was influenced by size, feeding habits and metabolic rate in addition to the activity density of the water. Changes in operation of nuclear reactors have resulted in progressive inc… more

Aerodynamic characteristics at supersonic speeds of a series of wing-body combinations having cambered wings with an aspect ratio of 3.5 and a taper ratio of 0.2: Effects of sweep angle and thickness ratio on the static lateral stability characteristics at M = 2.01

Description: Report presenting an investigation in the 4- by 4-foot supersonic pressure tunnel at Mach number 2.01 to determine the effects of sweep angle and thickness ratio on the static lateral stability characteristics of a series of wings with taper ratio 0.2 and aspect ratio 3.5. The results are presented with little analysis.

Analysis of V-g records from the Grumman F8F-2 airplane

Description: From Introduction: "In the present paper, which supplements reference 1, V-g records obtained from F8F-2 airplanes in 1949 are analyzed statistically to determine the frequency of experiencing large values of normal load factor and airspeed. These results are compared with the results from the F8F-1 airplane."

Argonne National Laboratory monthly progress report, April 1952

Description: This progress report from the Argonne National Laboratory covers the work in Biological and Medical Research, Radiological Physics, and Health services for the quarterly period ending March 31, 1952. Numerous experiments were conducted in an attempt to answer some of the questions arising from exposure to ionizing radiation, especially X radiation. Some of the research involved the radiosensitivity of cells and some involved animals. The effects of radium in humans was also evaluated. Other stu… more

Continuous Solvent Recovery Process Using Pulse Contacting Column

Description: From abstract: "This report presents the progress in the laboratory development of a continuous solvent recovery process for the tributyl phosphate-diluent mixture used in the Purex Process. Investigations were made with 1/2" diameter pulse columns, using a nine foot sodium carbonate contacting column and a four foot water wash column."

Design and construction history, Aquatic Biology Laboratory: Project C-364, December 31, 1951

Description: The GE Nucleonics Division Staff Department which now is called the Radiological Sciences Department was formerly known as the ``Health Instrument Divisions. A part of this department, presently known as the Biology Section, was formerly identified as the ``Biology Division.`` This project is concerned with a laboratory facility which is being built for the use of the Aquatic Biology Unit of the Biology Section. The Aquatic Biology group was established in 1945 to study the effect of the pile e… more
