The elements Sn, Mg, Ti, Zr, Hf, Si, Cd, and U were alloyed with plutonium to determine their effect on stabilization of the beta phase. Zirconium was found to be the ' most effective. Kinetic studies were conducted on Pu-Zr alloys having 0.24, 0.65, and 1.7 at.% Zr contents. The beta to alpha transformation in the Pu-Zr alloys was somewhat similar to that in unalloyed plutonium. The main difference being that time, temperature, transformation curves of the alloys were shifted to the right as the zirconium concentration increased. It was determined that the amount of beta phase retained at room temperature increased as the zirconium concentration increased. The minimum amount of Zr needed to stabilize the beta phase of plutonium at room temperature was determined to be 2.0 at.%. A 2.4 at.% Zr addition stabilized the beta phase of plutonium at atmospheric pressure from room temperature to 265 deg C. During mechanical property testing it was determined that the stabilized beta Pu-2.4 at.% Zr alloy was brittle from room temperature to 230 deg C. Both tensile and compression strengths of the beta stabilized alloy were greater than the unalloyed beta phase of plutonium. A brittle-ductile transition was noted between 130 …

Submitted to Univ. of Minnesota, Minneapolis. The gas model of neutron thermalization for a general moderator mass was studied by formulating the thermalization process as an integral equation. The relation of the model to the slowing-down theory was investigated. A discussion of the theory of scattering cross sections for neutrons is presented. The Wigner-Wilkins model was considered for moderator atoms of the same mass as the neutron. The analysis was extended to the case of a gaseous moderator with atoms of general mass. (M.C.G.)

It is the purpose of the present study to add to the growing source of information, so valuable to curriculum makers, by studying the relationship of certain background variables to the Negro girl's curriculum in foods. The background variables included in this study are age, siblings, residence, father's occupation, and mother's education.

The purpose of this paper is to develop some of the more basic Fourier transforms which are the outgrowth of the Fourier theorem. Although often approached from the stand-point of the series, this paper will approach the theorem from the standpoint of the integral.

The purpose of this paper is to trace some of the accepted characteristics of the devil to their origins through a study of folklore and ancient religions. The characteristics include the principal form taken by each devil and trace its beginnings through folklore; the animals connected with these devils; powers allotted to these devils; and purposes served by these devils.

The purpose of this thesis is two-fold: it is (1) to show Emerson's development of a consistent and fully formed theory of education which may well have value for the present time, and (2) to analyze the main aspects of this theory in detail for a better understanding of Emerson's thought.

It is the purpose of this investigation to quantitatively assess the effect of halo in peer ratings of individuals in the areas of friendship, mental ability, and level of anxiety, by identifying the discrepancy between these ratings and the measurement of these characteristics by standardized tests.

The United States suffered a rather severe diplomatic defeat in the collapse of the Nationalist government of China following World War II. It may be possible, by reducing the policy to its essential elements, to determine if a course of action in one given component of the policy was correct or in error, or if it is the usual gray area--neither black nor white, neither totally correct nor totally in error--that defies a valid conclusion.

This thesis is significant for the knowledge it offers concerning the influence of Napoleon Bonaparte's personality and career upon the character and the work of Lord Byron. It is significant because of the light it throws on both Napoleon and the culture of Europe during his era. This study is significant in the insight it indirectly gives into the psychological phenomenon of hero-worship, to which it gives a more universal application through the medium of Byron's attitude toward Napoleon.

The purpose of this study is to get some concrete evidence that group principles can be applied to church groups in an effective manner. The more immediate purpose is to improve the relations in the individual classes so that they will have a feeling of belongingness, relatedness, or close affiliation. It is the purpose of this experiment to help these individuals find the fulfillment of their personal needs that can be supplied in the Sunday School class.

The purpose of this investigation is to study the writings of Baroja to ascertain what his social and political ideas were, and to determine if these ideas changed, as evidenced in a comparison of his earlier and later writings.

The intent of this study was to supply more data to further potential investigations in the systematic study of the normal personality as described in previous paragraphs.

The purpose of this study is fourfold: (1) to investigate any differences in self-concept scores of a normal (adjusted) and abnormal (maladjusted) population; (2) to investigate any difference in self-concept scores between psychotic and non-psychotic hospitalized patients, (3) to investigate changes in self-concept concomitant with psychotherapy, and (4) to investigate any sex differences in self-concept.

There appears to be a vacillation from the original intent of the Employment Act of 1946. It was originally intended to serve as a tool whereby the smoothing and the easing of cyclical fluctuations of the business cycle could be facilitated. It now seems as though this tool has become one which is being used to correct those structural weaknesses which exist in the economy.

The purpose of this study is to attempt to determine what influence configuration and/or letter sequence have on the recognition thresholds of words. It is felt that low configuration and/or rare letter sequences will result in lower recognition thresholds, while high configuration and/or common letter sequence will result in higher recognition thresholds when stimulus words are presented to subjects by means of a tachistoscope.

This thesis will be mostly concerned with the twentieth-century criticism of Othello; some attention will be given to earlier criticism to determine to what extent twentieth-century criticism fits into patterns of thinking before the twentieth century. Some consideration will be given to the background of Othello before taking up the various aspects and periods of criticism.

The purpose of this study is to record the political attitudes of the major Edwardian novelists as they surveyed their contemporary world, diagnosed its maladies, offered suggestions for reform, and attempted to predict the course political life would take in the future.

This paper explores what kinds of paintings do children of a particular locale really like and what are some of the reasons for their choices. This information could be of use in planning methods of developing and nurturing aesthetic experiences through more wisely chosen reproductions of masterpieces of paintings.

The preparation of 3B-(2-mercaptoethylamino)-cholestane was set as the goal of this thesis project.

The present study of an ideal mixture for thrown ware is an outgrowth of a long-time personal interested developed during undergraduate work at North Texas State University. While a natural earthenware clay proved to be the best all-purpose clay for class use, it was not ideal for throwing.

The primary objective was to investigate the effectiveness of short-term group guidance and short-term individual counseling with freshman college students. The design utilizes the method and procedure of comparing similar groups of students who received group guidance, students who received individual counseling, and students who received no counseling or guidance. A comparison of the ratio between self-ratings and objectively evaluated test scores before and after the study served as the basis for determining the effectiveness of the experimental variables.

This study was made to determine the relationship between n Achievement, the McClelland technique measure of achievement motivation obtained from picture-story protocols, and academic achievement in elementary school children. The California Achievement Tests Battery was used as the criterion for academic achievement.

The purpose of the study was to determine trends between selected factors in the study. Trends between thirty position qualifications and proficiency with children, proficiency with staff, education, age, sex, and length of service were examined, trends between the type of institution, areas of duty, and general proficiency were also examined.
