Report presenting a wind-tunnel investigation of a model equipped with a 60 degree delta wing and a 60 degree delta horizontal all-movable canard control surface to determine the stability, control, and canard-surface hinge-moment characteristics at low speeds and at a Reynolds number of 9 x 10(exp 6). Two longitudinal positions of the canard surface were tested. Results regarding lift and pitching moment, drag, and hinge moment are provided.

From abstract: Elk Ridge is in southeastern Utah in the central part of San Juan County. It forms a conspicuous ridge on the north end of the Monument upwarp. During the summer of 1953 field work was largely restricted to South Elk Ridge, that part of Elk Ridge which is south of The Notch. Permian and Triassic sedimentary rocks crop out in the area and Jurassic and Cretaceous rocks are exposed east of the area.

From introduction: "This report covers the development of nondestructive techniques for measuring quantitatively: (1) thickness of electrodeposited-nickel diffusion barriers, and (2) thickness of aluminum cladding on flat-plate fuel elements."

During the first 15 months of operation of the Redox process, it was clearly demonstrated that in the absence of any pre-solvent extraction treatment of the starting metal solution, ruthenium contributed from 75 to 95% of the remaining fission product activity in both the final uranium and plutonium streams, and that three solvent extraction cycles were able consistently to produce, at best, only marginal quality product. This precarious position was further endangered by a three-fold reduction in the gamma radioactivity specification for recovered uranium shipped from Hanford, and by increased power levels in the reactors, resulting in still higher fission product concentrations in Redox feed solutions. The purposes of this review are to summarize briefly: (1) the chemistry of Ru in the Redox process; (2) the permanganate head-end treatment and its associated problems in plant operation; and (3) alternate possibilities for the elimination or control of Ru, including those which might solve the permanganate process difficulties. It is also the purpose of this document to present a selected bibliography on the subject of ruthenium specifically for those points under discussion herein. 17 refs.

Technical report covering the work done to explore heat transfer analytically and experimentally in liquid metals in turbulent flow within the thermal entrance region of circular tubes having uniform well temperature. Includes implications of this research. [From Summary]

The process of age calculation for Hanford exponential lattices containing aluminum-matrix slugs, where the sums run over the materials of the lattice cell.

The following calculations have been made at the request of H.R. Schmidt to determine the probability that self-radiation may play a substantial role in the decomposition of the ruthenium tetroxide in the reflux scrubber, section of the Redox Ruthenium Oxidizer (H-4). The validity of the derived data necessarily depends upon the correctness of the basic assumptions made with regard to process conditions and to possible radiation-activated mechanisms of disintegration. It is estimated that the extent of solid ruthenium formation in the tower which results from radiation effects should not exceed 100 micrograms per batch. This rate is negligible compared to that now found in the presence of stainless steel packing, or to that which might be expected from thermally-activated disintegrations alone.

Report discussing details of the design for the Bevatron at the University of California Radiation Laboratory. The Bevatron is a "6-billion-electron-volt (Bev) proton synchotron. This device will receive a 10-million-electron-volt (Mev) proton beam from a linear accelerator, and further accelerate a reasonable percentage of these protons, at a nominally constant radius of 600 inches, to a final energy greater than 6 Bev."

This report follows the work on the Kjedahl digestion procedure in sealed tubes at 470 C. as well as analyzing factors influencing ammonia decomposition within these tubes.

Report discussing experiments to evaluate ion sources for possible use in a thermonuclear reactor.

The following document describes how to determine the measurements of the optical density or absorption spectra of suspensions of micro-organisms.

This document presents a summary of work and progress at the Hanford Engineer Works for May 1954. The report is divided into sections by department. A plant wide general summary is included at the beginning of the report, after which the departmental summaries begin. The Manufacturing Department reports plant statistics, and summaries for the Metal Preparation, Reactor and Separation sections. The Engineering Department`s section summaries work for the Technical, Design, and Project Sections. Costs for the various departments are presented in the Financial Department`s summary. The Medical, Radiological Science, Utilities and General Services, Employee and Public Relations, and Community Real Estate and Services departments have sections presenting their monthly statistics, work, progress, and summaries.

Abstract: An area of high anomalous radioactivity and visible uranium minerals is associated with a nearly vertical north 70° west trending shear zone.

The carbon cycle of photosynthesis is briefly reviewed in its entirety and the experiments involving it which led to the implication of disulfide rupture in photosynthesis are indicated. A review of the organic, physical and photochemistry of disulfides, with particular reference to the five-membered disulfide rings as they appear in thioctic acid, is given.

Recently experimental evidence has accumulated showing that high-energy collisions of protons with various nuclei induce a considerable polarization in proton beams, and a mechanism has been proposed to account for this effect.

Report of findings from various tests: "Model investigations of the surges occurring in sewer lines and of the flow conditions in a typical pumping plant, used to dispose of drainage during high river stages, were conducted as a part of the local flood protection project for Louisville, Kentucky. Studies conducted on a 1:32 scale simplified model of the Southern Outfall Sewer provided general information on the relative amount of relief from surges to be expected from the pumping station and manholes in the sewer line upstream" (p. v).
