100-B Area flow analysis
Results of experimental programs indicate that it might be desirable in the future to modify the existing reactors by replacing the aluminum process tubes with tubes made of a zirconium alloy. The zirconium tubes would be more corrosion resistant than the aluminum ones and would also be stronger at higher temperatures. These new tubes would have the same outer diameter as the present tubes (for ease of handling and in order to provide adequate graphite cooling) but would have a thinner wall (since zirconium alloy is both stronger and more expensive than aluminum). The inner diameter of the new tubes would, therefore, be greater than in the present tubes. In addition to the tube change, it might also be desirable to replace the existing solid fuel elements with those known as ``I&E`` alements. These pieces would be similar to the present elements except for a longitudinal hole which would allow the passage of cooling vater through the center. The element would then be Internally and Externally cooled, and would have a more uniform temperature distribution. The combination of the larger tube inside diameter and the central hole in the fuel element would result in reduced friction loss for the reactor …

[1902 Flood in Big Spring, Texas]
Photograph of the 1902 flood in Big Spring, Texas. There are buildings visible in the distance and to the right, as well as a train engine and a few cars filled with debris in the middle-left of the image. A man can be seen to the right in front of a small gate. Text below the image says "Flood in Big Spring in 1902 - [sic] Early settlers and particularly immigrants from Pennsylvania who came to work in the T&P shops, often wrote back about the sandstorms on the frontier. But now and then they had occasion to write about floods, too, which inundated the T&P yards. This view is east from Gregg Street." and "T&P Topics, Jun 1957, pg 21 - J. H. Bradford Photo."

Analysis of Stresses and Deflections in Top Support Grid, PWR Reactor. Final Report
The top grid of the PWR reactor core assembly is treated as a simply supported circular plate. The theory of plate is applied to the grid umder mechanical loads. The thermal stress problem is analyzed by treating the plate as under combined action of a laterally distributed load and forces in the middle plane of the plate. The load distribution is calculated from the temperature variation over the grid. The thermal stress problem then is equivalent to two problems: one, of bendimg of plate; and, the other, a plane stress problem. The theoretical formulation for plates under nonuniform heating is developed by neglecting the effect of uneven expansion in the direction perpendicular to the plane of the plate. In replacing the partial dffferential equations by difference equations, the latter are modified to take into account the change in tbickmess and spacing of the grid webs near the boundary. Twentythree difference equations for the twenty-three stations in one octant of the grid are obtained for each second order partial differential equation. The difference equations are solved by assuming that the twisting moments and shearing stresses in the plane of the grid vanish at the boundary. The stresses and deflections due to …

An Analytical and Descriptive Technique for Rating Student Teachers
The problem of this study was to develop an analytical and descriptive technique for rating the performances of student teachers. In order to arrive at a solution to this problem, the following sub-problems were to be solved; namely, 1. To develop and validate a set of criteria for describing and rating the performances of student teachers; 2. To develop and validate a descriptive rating scale utilizing those criteria; 3. To develop a technique for using this descriptive rating scale; 4. To establish reliability of the instrument and to demonstrate the ability of the instrument to perform its intended functions.

CHARACTERISTICS OF THE SOLID STATE TRANSFORMATIONS IN-URANIUM
The purpose of the investigation was to determine the temperature dependence of the lattice parameters of U from room temperature to the melting point and to provide experimental data on the general characteristics and kinetics of the allotropic transformations in U. Toward this end high-temperature x-ray diffraction, electrical resistance, and sonic experimental techniques were employed. The data presented are interpreted in terms of the known physical, mechanical, and structural properties of the metal and are intended as a contribution toward the complete experimental and theoretical description of the allotropic transformation processes in pure U.

Charts for estimating the effects of short-period stability characteristics on airplane vertical-acceleration and pitch-angle response in continuous atmospheric turbulence
Report presenting charts for estimating the effects of variations in short-period stability characteristics of a rigid airplane on its root-mean-square vertical-acceleration and pitch-angle response to continuous atmospheric turbulence. A comparison of the root-mean-square vertical-acceleration response of an airplane free to be disturbed in vertical and pitching motion with that of an airplane free to be disturbed only in vertical motion indicates that the responses are similar for a nearly critically damped airplane.

The combinations of thermal and load stresses for the onset of permanent buckling in plates
A simple and practical method for evaluating the onset of permanent buckling in plates in the presence of combined thermal and compressive load stresses is outlined. A particular application of the method shows reasonable agreement with tests of 17-7 PH stainless-steel square tubes. The results indicate that the compressive load stress which the plate can support at the onset of permanent buckling is substantially reduced as the temperature difference of the plate and adjoining members increases.

A Comparative Study of Three Sonatas for Solo Brass Instruments and Piano by Paul Hindemith
In the years during the writing of The Craft of Musical Composition, and for the next few years afterwards, Hindemith was engaged in writing a solo sonata for each of the instruments of the orchestra. Muser states that this series of sonatas continues a definite policy of providing music for people who want to play music, and not merely to listen to it. The three sonatas for solo brass instruments and piano were written during this period. The sonatas, written for trumpet, horn, and trombone, were written in the following order: Sonata for Trumpet and Piano—1939; Sonata for Horn and Piano—1939; Sonata for Trombone and Piano—1941. These sonatas, being written rather closely together, should have certain stylistic characteristics in common, and there should also be certain features peculiar to each sonata. To study these sonatas and compare them with each other structurally and stylistically is the purpose of this work.

Design and experimental evaluation of a light-weight turbine-wheel assembly
Report presenting lightweight design concepts, which were developed and tested in a full-scale turbine wheel with a tip diameter of 34.3 inches and a tip speed of 1190 feet per second. It consisted of a rotor of two thin alloy disks attached with spacers and bolts and hollow turbine blades. Testing indicated that it would be particularly applicable to an expendable missile engine.

DEVELOPMENT OF A BATCH PROCESS FOR THE PRODUCTION OF A ZrO$sub 2$-UO$sub 2$ SOLID SOLUTION
A batch process on the 2 kg scale was developed for the production of ZrO/sub 2/--UO/sub 2/ solid solution in the weight proportion of about 4 to 1. The product is tetragonal ZrO/sub 2/-- UO/sub 2/ solution, with no UO/sub 2/ lines showing on the x-ray powder diffraction patterns. The solid solution is prepared from a precipitate of Zr(OH)/sub 4/-- (NH/sub 4/)/sub 2/U /sub 2O/sub 7/ which is filtered, dried, milled, screened to minus 325 mesh, and heated at 9OO deg C in H/sub 2/ for 4 hours. The success of the preparation depends strongly on the conditions of the precipitation, with precipitation from dilute salt solution being necessary to avoid undissolved UO/sub 2/ in the final product.
