Note presenting a review of the data existing in the literature and experimental measurements made in order to obtain the physical properties of white fuming nitric acid. The main object of the investigation was to obtain reliable values of the thermal properties of concentrated nitric acid for use in correlating the data obtained in heat-transfer research and in fluid-friction-characteristics investigations.

Discussing evidence of the potential of uranium in Greece

Report containing geologic and vein maps for part of the Central City District, Colorado. Tables containing Shafts and adits in the area are included.

Abstract: A four-week reconnaissance of certain portions of the mountainous area in Gila and Pinal Counties, Arizona, was undertaken in March and April, 1953, to inspect accessible outcrops of Dripping Spring quartzite, a pre-Cambrian formation which has lately attracted the interest of the Atomic Energy Commission by the discovery of two separate occurrences of uranium mineralization. Although no new deposits were found during the field work, a more thorough examination of the quartzite seems warranted. Recommendations for further prospecting by airborne and ground methods are presented in this report, and are based largely on observations made during the brief visit.

Discussing a reconnaissance examination of certain portions of the mountainous area in Gila and Pinal Counties, Arizona, undertaken to inspect accessible outcrops of Dripping Spring quartzite.

Introduction: A radiometric airborne reconnaissance of the Cameron, Arizona, district was conducted in the late fall of 1952 and early winter of 1953. Flying was carried out under the direction of the Salt Lake Exploration Branch of the Atomic Energy Commission, Division of Raw Materials. Airborne equipment and ground personnel were provided through the Technical Services Branch of the Grand Junction Exploration Division.

A preliminary report regarding exploration in the Atkinson Mesa Area, Montrose County, Colorado

Abstract: Preliminary studies of the Wallapai Mining District and selected properties in the Maynard and Greenwood Mining Districts, Mohave County, Arizona, from January 8 to March 8, 1953, were made to determine the extent of uranium mineralization. All of the uranium properties examined are of the vein type and are believed to be of mesothermal origin. Brecciation and porosity of the veins appear to be controlling factors in the concentration of uranium minerals from the ore-bearing solutions. Although the uranium minerals present in these districts have not been specifically identified, they appear to be mostly primary with very minor occurrences of secondary products. One exception is the State mine in the Greenwood District, where secondary minerals predominate.

Report discussing radioactivity measurements of samples of coal and associated rock that were collected during a reconnaissance study in the coal fields of eastern Kentucky, as well as Logan and Mingo counties, West Virginia.

The following report covers a reconnaissance study that was made of radioactivity of coal and associated rock in the coal fields of eastern Kentucky and Logan Mingo counties, W. Va. Samples of coal, carbonaceous shale, marine shale, flint clay, and dike rock were discovered and radioactivity within these samples were measured.

"The purpose of the reconnaissance was to determine the distribution and the economic importance of the radioactive occurrences of the region. The methods, as well as the results, of the investigation, are given in this report."

Report presenting testing of the vapor-oxidation of iscooctane at 550 degrees Celsius under conditions leading to rapid quenching of the reaction yielding hydrogen peroxide, diiosbutylene, and isobutylene as the major reaction products. Results regarding isooctane, n-Heptane, 2,2,5-Trimethylhexane, isobutane, and hydrogen-peroxide formation are provided.

The following report covers a reconnaissance for uranium-bearing carbonaceous rocks that was made during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. This report discusses uranium samples discovered withing these locations, however it was determined that none of the deposits discovered have commercial possibilities.

Report discussing a reconnaissance for uranium-bearing carbonaceous rocks during the 1952 field season in 23 areas in Colorado, Utah, Idaho, and Wyoming. From Abstract: "Uranium in small amounts occurs in several of the areas examined, but no deposits were found that might have commercial possibilities."

The following report covers a reconnaissance for radioactive materials that was made in parts of Maine, New York, New Jersey, and Pennsylvania. It's primary objective was to examine the iron ore deposits and associated rocks in Adirondack Mountains of New York and the Highlands of New Jersey. Additionally, several deposits known or reported to contain radioactive minerals were examined to delimit their extent. However, most of the deposits examined are not significant as possible sources of radioactive elements and the data pertaining to them are summarized in tables provided.
