Transient Temperature Distributions in a Thermally Orthotropic Plate With Non-Uniform Surface Heating

Description: ent temperature variation in a thermally orthotropic plate which is subjected to an arbitrary heating rate distribution along one face with all other surfaces being insulated. Dimensionless temperature histories and distributions determined from this solution are presented for the special, but representative, case of a linearly varying heating rate distribution on plates with varying degrees of thermal orthotropy. These results establish quantitatively the value of a material with high planar a… more

A Theoretical Study of the Transient Operation and Stability of Two-Phase Natural Circulation Loops

Description: Mathematical models of the time-dependent behavior of two-phase natural- circulation loops were used to predict the operation and to explain the unusual instability sometimes observed. The initial results obtained for a loop similar to the Univ. of Minnesota loop were used to formulate a more complex and accurate model, and the predicted transient behavior was in close agreement with the experimental results from the Minnesota loop. For a 300psia, high-pressure loop, unstable oscillatory behavi… more

Dynamic Simulation of Multi-Pass Pressurized Water Nuclear Power Plants by Analog Computer Techniques

Description: A kinetic model of the primary loop of a multi-pass pressurized water reactor power plant is developed to evaluate, by analog computer techniques, the transient response characteristics under conditions of steam generator load and reactor control rod perturbations. Using the 2-pass 28 Mw(t) SM-2 reactor as a typical plant, transient behavior patterns are illustrated and examined for a variety of load inputs, variations in plant constants, and analog model simplifications.

THE CARRIER-RECOMBINATION BEHAVIOR AND ANNEALING PROPERTIES OF RADIATION- INDUCED RECOMBINATION CENTERS IN GERMANIUM

Description: Carrier recombination and annealing of radioinduced recombination centers were investigated for both n- and ptype Ge. The experimental results are explained by a model in which recombination occurs at 0.36 ev above the valence band in gamma -irradiated, n-type Ge; the position of this level is shifted slightly downward for neutron-irradiated Ge. Trapping levels occur in As-doped Ge (at 0.17 ev above the valence band) which are not present in Sb-doped Ge. For p-type Ge, an energy level present i… more

The Brahms Variations on a Theme of Paganini and the Rachmaninoff Rhapsody on a Theme of Paganini

Description: Born April 2, 1873, on the estate of Oneg in the province of Novgorod, Russia, Sergei Vassilyvitch Rachmaninoff was the fifth of the six children of Vassili and Lyoubov Boutakova Rachmaninoff. Rachmaninoff's aristocratic descent was traced to the Hospodars Dragosh, rulers of the realm of Molday from the fourteenth to the sixteenth century. One of the daughters from this family had married a son of the Grand Duke Ivan III of Moscow. The son's nephew was named Rachmanin, and from this source the … more

Sex-Role Identification as a Determinant of Choice on the Bonney-Fessenden Sociograph

Description: It is the purpose of this study to utilize three psychometric measures in order to quantitatively assess the group of subjects on the basis of the trait heterosexuality, as measured by the Edwards Personal Preference Schedule, and in turn make predictions on the basis of these data as to choices made on the Bonney-Fessenden Sociograph.

Factors Involved in the Antibiotic Sensitivity of Staphylococcus Aureus

Description: It was the purpose of the present investigation to determine if sensitivity to other antibiotics can likewise be affected by subjecting S. aureus to heparin contact. It is of special interest in this problem to determine whether heparin in some manner affects the combining process of penicillin with the cells of several strains of S. aureus.

The Effect of Repeated Antigen Injections on the C' and C'4 Titers in Guinea Pig Serum

Description: In this study the effects of repeated antigen injections on total complement (C') and C'4 of guinea pig serum were investigated to determine if constant antigenic stimulation would show changes in the C' and C'4 titers. Attempts were also made to correlate any changes with variations in antibody titers during the repeated antigen injections.

Dostoyevsky's American Reputation to 1930

Description: Undoubtedly, Dostoyevsky's influence upon the novel is great, but, even yet, few concrete studies have been made and no full-length study has been published. It is hoped that this account of Dostoyevsky's reputation in America during the 1920's will be of assistance in the greater task of tracing Dostoyevsky's influence.

The Runge-Kutta Method

Description: This paper investigates the Runge-Kutta method of numerically integrating ordinary differential equations. An existence theorem is given insuring a solution to the differential equation, then the theorem is modified to yield an analytic solution. The derivation of the method itself is followed by an analysis of the inherent error.

The Use of the Mask in the Plays of Eugene O'Neill

Description: The purpose of this thesis is to indicate the use of the mask by Eugene O'Neill. It is probably possible to say that the mask has been used or implied in all of O'Neill's works, but this thesis will be confined to discussion of the works in which the mask or the implication of the mask is specifically evident.

The Relationships between Eight Situational Factors and High and Low Scores on the Leadership Behavior Dimensions of Instructional Supervisors

Description: The problem of this study was to determine whether there is a significant relationship between certain situational factors and high and low scores on the leadership behavior dimensions of industrial supervisors. The behavior dimensions studies were the two dimensions of Consideration and Initiating Structure, as measured by the instrument used in the study.

A Field Follow-Up Study of Beginning Elementary Teachers

Description: The present study was made to determine the relationship between the level of teaching effectiveness of beginning elementary teachers and three individual characteristics of prospective teachers. A secondary purpose was an attempt to improve the service rendered by the School of Education at North Texas State College, Denton, Texas, in the selection and guidance of students who indicate a desire to enter the program for preparing elementary teachers.

The Factors Influencing Out-of-State Companies to Establish Manufacturing Facilities in Dallas County

Description: "The purpose of this study was to collect and analyze locational data on all branch maufacturing plants established in Dallas County in 1954, 1955, and 1956; these data were acquired through personal interviews in 1957. For comparative purposes the same data on branch plants established in 1959 were obtained in 1960. The following elements of the locational process were determined and analyzed: 1. Origin and character of the new plants; specifically location of home office, types of products, s… more

A History of the Osage Indians Before Their Allotment in 1907

Description: The history of the Osages from 1808 to 1839 may be conveniently divided into three major sections, each separated by a cession treaty. The first begins with the cession treaty of 1808 and terminates with the cession of 1818. It covers the Osages' relations with the whites and the eastern tribes during that decade. The second section begins with the 1818 session treaty and ends with the land cession of 1825. It likewise covers the tribe's relations with the eastern tribes and the whites. The con… more

Aspects of Idiomatic Harmony in the Harpsichord Sonatas of Domenico Scarlatti

Description: Most of Domenico Scarlatti's harmonic progressions are quite orthodox when considered abstractly or free of their positioning in the score. The harmonic movement is given interest by subtle alterations in time; for example, (1) simultaneous upper and lower voices of different lengths, when repeated several times, change their relationship with each other; (2) one voice may be simply delayed so that it lags behind the other voice, thus combining to produce irregular harmonic sound on many succee… more

Demographic Trends in the Older Population of Texas, 1900 To 1960

Description: "The purpose of this thesis is to examine the age structure of the population of Texas as it existed in 1960, and insofar as possible to trace important changes and trends in the older group from 1900 to 1960. The qualification derives from the fact that at this time not all of the data from the 1960 census are available, and hence many trends can be described only through 1950. Where appropriate, the structure and trends characteristic of the total population will be described, usually for com… more
