Surface to Mass Dependence of Effective Resonance Integrals for Uranium 238 Cylinders
Technical report outlining the determination of the effective resonance integral for U238 as a function of the mass ratio for cylinders of 5/8" to 3" diameter. Also gives a linear approximation of the effective resonance integral with infinite shielding in the form of a function. [From Abstract]

Geology and Mineralization of Hunt's Mesa, Monument Valley, Arizona, Navajo County with Recommendations for Exploration Drilling
Abstract: Hunt's Mesa was examined on June 2 and 3, 1951, by the writer assisted by R. C. Cutter. Two channels were located and studied. Outcrops of the channels are mineralized, the mineralization being of the copper-uranium variety. There are indications that an appreciable quantity of ore can be found by exploration drilling. A program of 25,000 feet of wagon drilling is recommended.

Numerical Technique for Criticality Calculations on Hydrogen Moderated Reactors
"The purpose of this memo is to set down a derivation and numerical technique for a method that can be used for criticality calculations on bare reactors containing hydrogen together with another moderator such as BeO. The method and notation are that of G. Goertzel (NDA)-1, and D. Selengut (NEPA). In the interest of the computers, the numerical technique, associated notation, and calculation form are modeled after that currently used by the ANP Physics Group for BeO moderated reactors."

Precision of the Photographic Spectrochemical Assay of Uranium 235 at Low Concentrations
Abstract: "A series of experiments was carried out to determine the precision of the spectrochemical procedure for the isotopic analysis of uranium, especially at low uranium 235 concentrations. Standards were prepared from uranium hexafluoride which had been assayed on the mass spectrometer with a 95 per cent confidence interval of 0.5 per cent of the amount present. For a determination consisting of 9 separate measurements, the best precision obtained at normal concentration on the 95 per cent confidence interval was 0.711 +/- 0.112 per cent uranium 235 (16 per cent of the amount present)."
