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 …

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.

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.

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.

Polymetrics is a one-movement work for symphonic wind ensemble, of approximately 8 minutes' duration. The instrumentation includes thirty woodwinds, thirteen brasses, and ten percussionists. The pitch organization is based on two hexachords that encompass all twelve pitch classes.

This sonata by Alban Berg is a product of Arnold Schoenberg's teachings and is, indeed, a musical reflection of the Schoenberg of 1907-1908. At this time the musical thought of Schoenberg himself was in a state of metamorphosis, developing from the chromaticism of the late Romantic composers toward the twelve-tone technique which he was to formulate a few years later. The sonata, as a whole and above all, reflects the growth of an important composer, one who is perhaps the most important link between the traditional Classical and Romantic schools and the modern schools. His growth was based on a thorough knowledge of traditional styles and techniques, vestiges of which are seen in the formal design, chromaticism, and evasive harmony of the work. His advance is seen in his peculiar use of polyphony and motivic variation. Compared with many other works for piano, Berg's sonata is perhaps not among the most celebrated. But as indication of the attitude of a great composer who wished to build upon rather than break with his heritage, it is a most significant work.

It is the object of this paper to review Sir Edward Elgar's life as a composer, and to discuss and study the thematic elements of his oratorio, "The Apostles." To understand and evaluate the significance of any person's rise to fame in his own field, it is necessary to reconstruct the surroundings from which he came. If a study of the musical conditions had been made when Elgar's development as a composer was starting to draw attention, it would have been noted that the British public was prepared to listen to music in newer forms only if it was from a country other than England. There was very little done or said to encourage any music in a modern character if it was composed by someone from England.
