From Abstract: "Age determinations have been made on 21 crystals of gem quality zircon from Ceylon which are believed to have been derived from pegmatites of pre-Cambrian age."

Discusses American foul brood, a disease caused by a spore that infects bee larvae. Describes how to diagnose and control the disease. Lists the types of bees resistant to the disease.

Note presenting a theoretical investigation of a general method for predicting the flow field behind the wings of plane and cruciform wing and body combinations at transonic or supersonic speeds and slender configurations at supersonic speeds. The effects of certain geometric parameters as aspect ratio,angle of attack and incidence, ratio of body radius to wing semispan, and angle of bank on the vortex wake behidn wings of wing-body combinations were studied.

Report discussing the occurrence and analysis of bastnaesite in the Redstone granite of the Sterling batholith near Westerly, Rhode Island.

Annual report of Brookhaven National Laboratory describing the work and findings for the lab's departments during summer 1953-1954.

From abstract: "In 1953 the Chattanooga shale in the Sequatchie anticline was tested for its uranium content by seven diamond drill cores. Concurrent with the drilling, geologic field work was done to determine the distribution, thickness, and structural setting of the shale." The report contains information regarding location and drainage, geology, the drilling program, subdivisions of the Sequatchie anticline, and unpublished reports.

"The results of an investigation of the Chattanooga shale along the Sequatchie anticline of Tennessee and Alabama are summarized in this report. The project was of an exploratory nature designed to 1) obtain fresh core samples from areas where analyses of outcrop samples showed uranium contents as high or higher than those of the Youngs Bend area in DeKalb County, Tenn.; 2) learn more about the distribution and thickness of the shale in those areas and, if necessary, do some geologic mapping; 3) observe general topographic, drainage, and geologic conditions that would affect the mining of shale."

A spectrophotometric method used in the determination of thorium was modified for the purpose of analyzing plutonium alloys which contained 0.01 to 0.8 percent thorium. Absorbance values were measured at 545 millimicrons for solutions containing thorium and thorin, the organic reagent added to form a colored complex with thorium in the presence of plutonium (III) . With plutonium-thorium 0.8 percent thorium, the average recovery of thorium was 99.6 +- 1.5 percent. For similar samples containing 0.01 to 0.2 percent thorium, the average recovery 101.0 +- 3.4 percent, after the thorium was separated from plutonium by precipitation of thorium fluoride with the aid of lanthanum fluoride as a carrier.

Report issued by the Bureau of Mines over investigations of coking-coal reserves of Mercer County, West Virginia. Methods used, and measurements of coal reserves are listed. This report includes tables, and maps.

Abstract: A study, consisting of field and laboratory work, was undertaken in an endeavor to establish possible structural mineralization controls associated with the copper-uranium occurrences in the Willaha area, Coconino County, Arizona. Uranium mineralization, apparent at present, is localized along small fissures and vugs and in certain beds and lenses of the middle member of the Kaibab formation(Permian). It is associated with copper and iron oxide staining. Though no definite ore controls were disclosed by this study, at least a limited program of shallow drilling is warranted on the property. This sub-surface exploration should determine possible extensions of known mineralized areas, explore surface radiometric anomalies, and provide data for the determination of possible guides to ore. Deeper exploration may encounter mineralization in other horizons of the Kaibab limestone.

Report presenting some information on landing-gear applied drag loads and on the nature of the wheel spin-up phenomenon in landing, based on a program of tests under controlled conditions in the impact basin. Results regarding fundamentals of the wheel spin-up process, comparison of the maximum loads in various types of tests, variation of coefficient of friction, and effect of prerotation are provided.

From April, 1951 to Aug, 1954, New York Shipbuilding Corp. carried out a subcontract with E.I. du Pont de Nemours & Company that was without parallel in the shipyard`s history. The work, designated the NYX Project for reasons of security, was vital to the operations of the Savannah River Plant, Aiken, S.C., which was then being designed and constructed by du Pont for the Atomic Energy Commission. It consisted of three broad parts: developmental and experimental work; fabrication and testing of a prototype unit; fabrication of production units. Five production units were ultimately built, one of them converted from the prototype. All were fabricated from stainless steel, and involved welding techniques, control of thermal distortion and tolerances never previously attempted on assemblies of comparable size. Du Pont`s technical experience and the background of New York Ship in heavy construction, particularly in the fabrication of naval gun turrets, were combined from the outset to resolve the difficult fabrication problems that occurred almost daily. Representatives of both companies worked together as a team in the shops and at supervisory levels to an unprecedented extent. The report is intended primarily to summarize New York Ship`s part in the project, but also includes some …

Average heat-transfer, temperature-recovery, and pressure-distribution measurements were obtained over the hemispherical nose of a body of revolution both with and without flow-separation spikes. The tests, conducted in a range of Reynolds numbers from 1.55 to 9.85 x 10(5) and from Mach number 0.12 to 5.04, indicated that in supersonic flow the addition of spikes approximately doubles the rate of heat transfer, regardless of spike length.

"The lift, drag, and pitching-moment characteristics of the AGARD Calibration Model B as determined in the Langley 9-inch supersonic tunnel are presented at Mach numbers of 1.62, 1.94, and 2.41 and at a Reynolds number, based on body length, of approximately 3.0 x 10(exp 6). The zero-lift drag data compared favorably with available data and were in the proper sequence for the effects of Reynolds number" (p. 1).
