The inelastic interactions of negative pi mesons with protons at 374, 417, and 454 Mev incident pi kinetic energy are studied by measuring the differential distributions of finalstate neutrons. The pi source is an internal target of the Berkeley 184-inch synchrocyclotron. A magnetic beamtransport system momentum-anaiyzes and focuses the pi beam at a liquid hydrogen target located in an adjacent shielded experimental area. The time-of- flight distribution of neutral particles is measured at various laboratorysystem angles between 10 and 65 deg. Neutral particles are detected by observing the charged products of their interactions in plastic scintillator. The time-of- flight information is determined electronically by time-to-height conversion and pulse-height analysis. The time resolution of the total system is 1.0 nsec. Detected neutral particles accompanied by charged particles are separated by the electronic system from those not accompanied by charged particles. Analysis presuming the principal inelastic reactions to be pi /sup -/p yields pi /sup +/ pi /sup -/n and pi /sup -/p yields pi /sup 0/ pi /sup 0/n separates the time-of-flight spectra into gamma rays, neutrons from the reaction pi /sup -/p yields pi /sup 0/n, and inelastic neutrons. Calculated values of the neutron- detection efficiency are used in the …

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 …

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.

The purpose of this thesis is to explore the available evidence concerning Eliot's theological beliefs--particularly as that evidence is found in his plays--in an attempt to define with as much accuracy as possible the understanding of Eliot's theology which provides the most adequate understanding of and enjoyment of Eliot's writings.

Effects due to elementary particle-like collisions within nuclear matter have been observed in several nuclear reactions caused by pions and protons. Simple nuclear reactions of the form ZA(a,an)Z/sup A-1/ and Z/sup A/(a,ap)(Z-1)/ sup A-1/ have excitation functions that are sensitive to changes in the elementary-particle cross sections. The excitation function for the reaction C/ sup 12/( pi /sup -/, pi /sup -/n)C/sup 11/ is measure d from 53 to 1610 Mev by bombarding targets of plastic scintillator with pions. The intensity of the pion beam is monitored with a two-counter telescope and 40 Mc scaling system. The scintillator target is mounted on a phototube and becomes the detector for the carbon-11 positron activity. Corrections are made for muon contamination in the beam, coincidence losses in the monitor system, carbon-11 activity produced by stray background at the accelerator, carbon-1l activity produced by secondaries in the target, and the efficiency of the carbon-11 detection system. The C/sup 12/( pi /sup -/, pi /sup -/n)C/sup 11/ cross sections rise to a peak of abo ut 70 mb at 190 Mev, that corresponds to the resonance in freeparticle pi /sup -/n scattering at 190 Mev. Calculations based on a knock-on'' collision mechanism and sharp-cutoff …

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.

This study was conducted in an effort to examine: (1) adolescents' concepts of their relationships with their families, (2) possible correlations between adolescents' percentile ranks indicated in family relationships with a limited number of other factors which appear to be associated with personal and social adjustment, and (3) any significant differences in responses of adolescent girls enrolled in homemaking education and those not currently enrolled in homemaking.

To provide a better understanding of civil government as taught in the public senior high schools of Texas, this study investigates the scope of subject matter now included in the course, the method of presentation of the students, and suggests possible improvement toward solution.

Since there has been an abundance of research concerning high and low social status and little on inconsistents, the present study intends to shed some understanding of this group by comparing their feelings and attitudes to the highs and lows. Four principle areas are emphasized: family relationships, attitude toward sex, interpersonal relationships and self concept, with sub-areas lending added data.

With the aid of the labor legislation passed during the New Deal era, it would appear that southern labor should have been as well organized proportionately as northern labor. Outwardly it would also appear that southern labor did not enjoy more success in organization because it was still docile and preferred to bargain on an individual basis, an attitude which met with the approval of the southern employer. However, the attitude of the individual southern worker does not explain what occurred in the South under the New Deal. Rather, other important factors retarded unionization: southern community attitudes, regional hostility to anything northern, southern courts, the national aspect of the New Deal and the various unions themselves. To understand the slow but continuous process of unionization in the South during the New Deal period, these factors have to be considered in their setting. Only here can the effect of the New Deal labor legislation be readily discernible.
