Preliminary Summary of Reconnaissance for Uranium in Arizona
From introduction: A reconnaissance of Arizona uranium deposits was started in October 1950 and continued through April 1951. A total of six man--months was spent by H. C. Granger, E. P. Kaiser, and J. W. Adams. About 40 properties were examined and, of these, six were mapped by plane-table method and six were sketch-mapped. This reconnaissance was not intended as a complete evaluation of all Arizona deposits; other areas and occurrences were not examined during the investigations and are not discussed in this report.

Geological Investigation of Mexican Cry Mesa, Lukachukai District, Arizona with Diamond Drilling Recommendations
Abstract: The Salt Wash member of the Jurassic Morrison formation of Mexican Cry Mesa, Lukachukai District, Arizona, was examined to determine size, grade, and distribution of contained carnotite deposits and the possibilities of developing reserves by exploratory drilling. Only three occurrences of carnotite-bearing sandstone were found in 17 miles of rim outcrop. Limited drilling is recommended in the vicinity of these exposures.

An Investigation of Aircraft Heaters 34: Experimental Determination of Thermal and Hydrodynamical Behavior of Air Flowing Between a Flat and a Wave-Shaped Plate
Report presenting an investigation of the thermal and hydrodynamical behavior of air flowing along a passage with one flat side, which was steam-heated, and one wave-shaped side, which was unheated. Two series of tests were conducted, one with the plates in direct opposition and one with the plates slightly separated, which induced turbulence upstream of the thermal boundary layer. Results regarding heat transfer and static-pressure drop are provided.

An investigation of aircraft heaters 36: preliminary investigation of a combustion-type aircraft heater
Report presenting experimental results on the thermal performance of an aircraft combustion-type heater. The performance of the heater with a counterflow and a parallel-flow return passage on the gas side does not appear predictable by use of existing equations. The thermal conductance for the gases within the combustion chamber is predicted to be many times lower than the experimental data indicate.

Effect of Stress-Solvent Crazing on Tensile Strength of Polymethyl Methacrylate
Note presenting an investigation of the loss of strength of tensile specimens of polymethyl methacrylate as a result of stress-solvent crazing at 23 degrees Celsius and 50-percent relative humidity. the materials tested were commercial cast polymethyl-methacrylate sheets of both heat-resistant and ordinary grades from each of two manufacturers.

Statistical Fluctuation of Intensity in Debye-Scherrer Lines Due to Random Orientation of Crystal Grains
Note presenting an exploration of the Debye-Scherrer diagram of a stationary polycrystalline sample, which has an intensity distribution with an erratic line because of statistical irregularities of the crystal grain orientation. The fluctuations of intensity are discussed for the case that the only causes of line breadth are the natural spectral width of the primary radiation and the finite size of the grains.

Kinetics of sintering chromium carbide
Report presenting an investigation of the sintering of chromium carbide under pressure in order to study the kinetics of grain growth and densification during this process. Densification of a sintered chromium carbide compact was accompanied by grain growth and density and grain size seem to be interdependent during this stage of the sintering process.

Skin Friction of Incompressible Turbulent Boundary Layer Under Adverse Pressure Gradients
Note presenting experimental data for skin friction of turbulent boundary layers under adverse pressure gradients from several sources in graphical form. Data obtained by the momentum-balance method are shown to follow a trend opposite to that of data obtained by hot-wire and heat-transfer methods.

A biharmonic relaxation method for calculating thermal stress in cooled irregular cylinders
Report presenting a numerical method for calculating thermal stresses in irregular cylinders cooled by one or more internal passages. The use of relaxation methods and elementary methods of finite differences was found to give approximations to correct values when compared with previously known solutions for concentric circular cylinders with symmetrical and asymmetrical temperature distributions.

Some Measurements of the Effect of Gaseous Imperfections on the Critical Pressure Ratio in Air and the Speed of Sound in Nitrogen
Note presenting experiments made to measure the speed of sound in nitrogen at room temperatures in the pressure range of 0 to 2000 pounds per square inch, and the critical pressure ratio of air expanded isentropically from stagnation conditions in the same range. The experimental results were compared with values obtained by using the Van der Waals equation and the Beattie-Bridgeman equation.

Wind-tunnel investigation and analysis of the effects of end plates on the aerodynamic characteristics of an unswept wing
Report presenting a wind-tunnel investigation to determine the effects of end plates of various areas and shapes on the aerodynamic characteristics of an unswept and untapered wing of aspect ratio 4. End plates were found to provide the basic wing with an increase in the lift-curve slope, a reduction in the induced drag, and an increase in the maximum lift coefficient.
