Submitted to Illinois Inst. of Tech., Chicago. A He/sup 3/ cryostat was built to measure the specific heat of rare earth metals which have a component, at low temperatures, attributable to the electrons in the incomplete 4f shell. The specific heat of dysprosium from 0.4 to 4.2 deg K was measured. Pertinent theories about specific heats are outlined. The apparatus included the cryostat, vacuum and He/sup 3/ systems, calorimeter, carbon thermometer, heater, and magnetic thermometer. The experimental procedure is described and results are presented in graphic and tabular form. The specific heat rose sharply below 1 deg K. An anomalous hump was centered about 2.35 deg K. (M.C.G.)

Submitted to Univ. of Tennessee, Knoxville. The fast neutron-induced fission cross section of U/sup 234/ was measured from threshold to 4-Mev neutron energy. A maximum of 1.26 barns was found at 850 kev followed by a minimum of 1.10 barns at 8050 kev. The angular ani-sotropy of the fragment distribution was measured for neutron energies from 400 kev to 4 Mev. Extrema in the ratio sigma /sub f//( sigma /sub f(90 deg ) were found at 500, 850, and 1050 kev; the distribution at 500 kev showing a maximum in the direction normal to the beam (side-wise peaking) while that at 850 kev showed a maximum along the beam direction. The distribution at 8050 kev showed forward peaking but to a lesser extent than for energies immediately higher or lower. The behavior was analyzed according to the theories of Bohr and Wheeler. The dip in cross section between 850 and 1050 kev is consistent with the suggestion of Wheeler that neutron competition in the decay of the compound nucleus enters with increased strength in this area. Vibration-rotational levels in U/sup 234/ beginning at 790 kev are known to exist and inelastic neutron scattering to these levels serves to depress the …

The problem is to study the relationship between two personality measures, self-concept and authoritarianism, as each relates to certain academic, vocational, and biographical variables of male freshmen attending a state-supported university in the Southwest.

Today's colleges and universities are faced with the challenges of reforming their curriculums in an effort to hold a generation of students who are now demanding more than just a degree. Today prominent writers in the field of higher education point to the necessity of assessing and reconstructing college courses so that new direction will be provided. Each student entering college for the first time usually must enroll in an English composition course. Such a course offers great potential to encourage the creative capacity of the incoming student and foster an attitude of personal inquiry. The diversity of subjects and intentions which can be introduced in the beginning composition course offers a healthy reservoir of opportunity for exploring personal meaning. Introducing some of the goals and concepts of creativity may thus inspire the design of a new course given to meeting the challenges of higher education.The problem of this study was to develop a course in freshman English composition based on the theories of creativity and directed towards the development of the student's creative and critical capacity.

This dissertation consists of four programs: one lecture- recital, two recitals for piano solo, and one (the Schubert program) in combination with other instruments. The repertoire of the complete series of concerts was chosen with the intention of demonstrating the ability of the performer to project music of various types and composed in different periods.

The problem of this study was to determine the status and practices of supervisors of secondary student teachers in Texas colleges and universities and to compare these practices with those practices recommended by national authorities in the field of student teaching.

The problem of this study was the prediction of aggressive, submissive, and normal student teaching behavior by the use of needs profiles from sociometrically defined groups of education students. The criteria profiles were constructed using beginning education students, and prediction was made on a student teaching population.

This study was initiated to determine the soundness of certain phases of the counseling and visiting teacher program in a selected school system of a metropolitan area. It was believed that investigation of those programs would prove to be of significant value to those individuals who were in charge of the guidance programs in those schools, and that ultimately the full benefits of these investigations would be received by the students.

This study was designed to determine the relationships between three variables in fifth- and sixth-grade classroom verbal interactions. These variables include sex of teacher, sex of pupil, and approval/disapproval interactions between teacher and pupil.

The problem of the study was to determine the effects of student use of Skill-Builder Controlled Reader training in facilitating skill development in beginning and intermediate typewriting classes at the college level.

The problem of this study was to determine the relationships between aptitudes and vocational and educational success and between aptitudes and vocational proficiency.

The purpose of this study was to evaluate the public relations programs in selected Texas public school systems. From this evaluation, criteria were developed which will enable the administrators, particularly those in smaller school systems, to maintain stronger public relations programs. These public relations programs were evaluated in terms of the elements of sound public relations procedures.

Test results are presented that show that a strong concrete weighing approximately 185 lb/ft/sup 3/ can be made using water, waste lead slag, and Ciment Fondu. Feasibility, materials, mortar tests, concrete tests, and Ciment Fondu concretes are discussed. A 24-in.-thick concrete shield wall would have to be increased in thickness by 5 in. if slag concrete is used in place of barytes or magnetite concrete. On a pound-for-pound basis, the waste lead slag concrete materials were 30% cheaper than barytes and magnetite concrete materials. (M.C.G.)

A simple theory of the photoproduction of pi /sup 0/ mesons from complex nuclei based on the impulse and closure approximation is studied. The theory is compared with an experiment of Goodwin, Anderson, and Kenney that shows the dependence of the number of decay gammas from pi /sup 0/ mesons photo- produced from various nuclei as a function of the atomic number at 45, 90, and 135 degrees for incident photon energies from threshold to 350 Mev. The dependence measured near threshold and at 45 degrees does not agree with the simple theory nor is it consistent with partial elastic production. By a method of Placzek and Wick the corrections to the simple theory are estimated, and found to be large near threshold. These corrections may explain the discrepancy between the theory and the experimental results. No information about the nuclear-pair correlation function is obtained. The impulse approximation is used to calculate the relative ratio of the radiative absorption rate of pi /sup -/ mesons absorbed in hydrogen and deuterium from an atomic s state. The calculated value of the ratio T = R( pi /sup -/ + d yields 2n + gamma )/R( pi /sup -/ + p yields …

Experimental studies of the relative atomic mu --meson capture probabilities in the constituents of chemical compounds are described. Fermi and Teller had predicted that the atomic-capture probability is proportional to the nuclear charge of the atomic species weighted by its atomic concentration. This is sometimes referred to as the Fermi-Teller Z law.'' Previous experiments indicated no clear systematics to this capture process, and there are conflicts between the results of several measurements made with the same or similar compounds. In these experiments the capturing atom was identified by detection of either mesic x rays or decay electrons from mu /sup -/ mesons bound in the mesic K shell in the atomic species, In these experiments oxides and sulfides of some medium- and high-Z elements as well as two metallic solutions were used, and a nuclear capture product (neutron) rather than the decay electrons was detected. Results show that among the substances examIned, namely CuO, Sb/sub 2/O/sub 3, PbO, CuS, Sb/sub 2/S/sub 3/, PbS AgLi, and CuAu, the Z law'' behavior is not indicated either in insulators or in metals, although in all cases there is a preference for capturing in the atom of higher Z. If the atomic-capture probability is …

A thesis about the String Septet. The author explains that it deals with problems concerned in the reconciliation of contemporary aesthetics with extensions of romantic harmony, classical and pre-classical form, classical figuration and ornamentation, and contrapuntal organization.

Polycrystalline aluminum-copper alloys containing 4 and 5% copper were given heat treatments designed to develop dispersions of Al/sub 2/Cu precipitate particles of various sizes and distributions. Tensile tests were performed on the dispersion hardened alloys at 4.2, 77, 90 and 114 deg K to determine the strain rate and temperature dependence of the flow stress. The intersection analysis of the tensile data showed that the dispersed particles significantly increase the average effective forest dislocation density produced for a given amount of strain. The increased dislocation density was found to be in qualitative agreement with selected electron-microscope observations of the deformed structure of the alloys. Estimates of contributions to the flow stress arising from effects coincident with the intersection of dislocations and those associated with the build-up of long range stress fields were made. The major strengthening contribution of the dispersed particles during plastic deformation is shown to be due to an increase in the dislocation density associated with relatively high density tangles of dislocations observed to be localized near particles and groups of particles.
