A Note on the Transient Gas Flow Problem
From abstract: "Expressions have been obtained for pressure distribution, velocity, volume flux, and total cumulative production of a gas well as a function of time after opening of a closed-down well... The calculations can be applied to problems involving short-term transient flow of gases, such as in experiments with radioactive tracers."

Preliminary Report of the Results of Reconnaissance for Uraniferous Materials in the Powder River Basin, Wyoming
From introduction: During three months of the summer of 1952, a geologic and radiometric reconnaissance examination for uraniferous materials in the peripheral parts of the Powder River structural basin in northeastern Wyoming (fig. 1) was made by the Survey on behalf of the Division of Raw Materials of the U. S. Atomic Energy Commission. The purpose was to find, describe, locate, and sample deposits of uraniferous or radioactive materials other than those in the central part of the Powder River Basin in the general vicinity of the Pumpkin Buttes.

Preliminary Report on Geologic Investigations in Monument Valley Area, Arizona, 1952
From introduction: A program of uranium investigations and geologic mapping on the Navajo Indian Reservation in Apache and Navajo Counties, northeastern Arizona (fig. 1) was undertaken by the U. S. Geological Survey on behalf of the Atomic Energy Commission during the field seasons of 1951 and 1952. Field work on this program has been completed and preliminary copies of the maps, which cover an area of about 700 square miles, are inclosed as part of this report. The two principal objectives of the program were to establish geologic criteria useful as guides in prospecting for uranium deposits, and to appraise the favorableness of the Shinarump conglomerate and other Triassic rocks for the occurrence of uranium deposits in order to select areas that deserve exploration for concealed deposits.

Preliminary Report on Geologic Investigations in White Canyon, San Juan County, Utah, 1952
From introduction: Field work, begun in the field season of 1951, was continued by the U. S. Geological Survey in the White Canyon area, San Juan County, Utah, from May 1 to October 28, 1952, The objectives of this work were to study the habits and character of uranium deposits in the area, to determine control and guides to ore and suitable areas for physical exploration, and to map and study the ore-bearing and adjacent strata to determine the regional geologic controls and habits of the uranium deposits, The White Canyon project is part of a regional mapping program on the Colorado Plateau being conducted by the Geological Survey on behalf of the U. S. Atomic Energy Commission.

Meson Production By High-Energy Neutrons
The angular distribution of charged x mesons produced by 300 <x> 30 Mev neutrons on C12 and Be9 have been studied. An analysis of the kinematics for meson production in a nucleon-nucleon collision indicates a fairly well defined center-of-mass system.

Preliminary Report on the Results of Geobotanical Prospecting on the South Flank of Haystack Butte, McKinley County, New Mexico
Abstract: The absorber plant method of geobotanical prospecting was tested systematically over the bench formed by the Jurassic Todilto limestone on the south flank of Haystack Butte, McKinley County, N. Mex. This portion of the bench includes the largest known uranium ore body in limestone and most has been extensively drilled by private enterprise. Geobotanical prospecting was accomplished to provide control data. Comparison of the geobotanical anomalies with the available drill hole information from the mining companies and Atomic Energy Commission geologists have shown that the known ore occurrences would have been outlined by the results of the tree sampling. In addition some geobotanical anomalies are indicated in drilled areas in which ore was not reported and in areas not physically explored at the time of sampling. These anomalies may represent mineralized ground below ore grade or new ore deposits.

The Comet and Gray Eagle Mines and Adjacent Area, Jefferson County, Montana
Abstract: Anomalous radioactivity and uranium minerals have been found on the dumps of the Comet, Gray Eagle, and Silver Hill mines situated along the Comet-Gray Eagle shear zone. The shear zone is from 50 to 200 feet in width and has been traced 5 1/2 miles. The Gray Eagle mine is currently being reopened but no underground work, with the exception of a few shallow shafts and adits, has been done between the Gray Eagle and Comet mines. Because of the high U3 08 content of the samples from the Comet and Gray Eagle dumps, it is recommended that a minimum of four diamond drill holes totaling 3, 000 feet be drilled by AEC between the two mines to intersect the shear zone 300 to 500 feet below the surface. This drilling should be made contingent upon the results of the Gray Eagle exploration.

Geophysical Investigations on the Gramlich Group, Paradox District, Montrose County, Colorado
From abstract: The U. S. Geological Survey made a geophysical investigation on the Gramlich group, Paradox district, Montrose County, Colo., during the period May 26 to July 11, 1952.. Electrical resistivity and self-potential surveys were made to determine the thickness of the upper Salt Wash sandstone and to test electrical prospecting methods in an area of shallow overburden. The investigations were made in conjunction with a diamond-drilling program.

Low-Lift Buffet Characteristics Obtained From Flight Tests of Unswept Thin Intersecting Surfaces and of Thick 35 Degree Sweptback Surfaces
Report presenting testing of two rocket-propelled research models to determine the effect of the intersection of thin aerodynamic surfaces and the effect of moderate sweepback of thick aerodynamic surfaces on low-lift buffeting. Results regarding trim changes and drag are also provided. It was discovered that low-lift buffeting may be induced at high subsonic speeds by interference due to the intersection of thin aerodynamic surfaces.

A Lead-Uranium Deposit at the White Oak No. 1 Mine, Santa Cruz County, Arizona
From abstract: A small quantity of uranium ore was shipped from the White Oak No. 1 mine, Pajarito mining district, Santa Cruz County, Ariz., in 1952. The uranium is associated with oxidized lead ore in a shear zone that cuts rhyolite 'porphyry of Tertiary(?) age. The uranium minerals -- kasolite, uranophane, dumontite, autunite, and possibly radioactive pyromorphite -- are concentrated along small, discontinuous fractures, and accordingly the ore bodies are small and widely dispersed.
