This quartet is comprised of two wind instruments, flute and clarinet, and two stringed instruments, violin and violoncello. This unusual combination affords a wide variety of colors in both melody and chord-voicing that are impossible with an "unmixed" quartet.

The electron flux spectrum resulting from the slowing down of electrons from /sup 64/Cu uniformly distributed in Cu was measured from 0.1 ev to 37 kev for both a plane disk source and a black body cavity source. The cavity source consisted of a hollow Cu frustrum with walls infinitely thick for /sup 64/Cu beta rays. A matching thick cover allowed only electrons from inside the cavity to enter the Keplertron, a spherical electrostatic beta spectrometer. The cavity data agreed well from 1 kev to 37 kev with a simplified calculation of the Spencer-Fano theory. Below 1 kev, the experimental flux exceeded the calculated flux by as much as 35% at 30 ev. A stopping power derived from proton dath was used in the theory for electrons below 5.5 kev. A buildup of several orders of magnitude in the electron flux below 1 kev was observed. The disk data was lower than the cavity data at all energies above 1 kev, the former approaching the latter at higher energies. The beth spectrometer was calibrated for transmission and resolution from 1.5 ev to 3 kev using an isotropic electron gun and at 31.4 kev using the /sup 152/Sm Auger line. (auth)

For this study, the forms of the movements of forty-four symphonies of Mozart-those appearing in the Breitkopf and Hartel "complete" edition of his works- were analyzed. For convenience of reference, the symphonies are discussed in this thesis in their conventional numbering-that of the Breitkopf and Hartel edition- except for six symphonies that appeared in a supplementary volume and are inserted in this study into their approximately correct chronological positions.

The significance of the application of valves to brass instruments will be better understood by a brief discussion of conditions immediately preceding this innovation.

There are two major purposes in selecting Couperin's programmatic clavecin pieces for study; to prove their importance in the evolution of programmatic music and to prove the value of their study by the modern pianist. Due to the enormous number of Couperin's programmatic pieces, a detailed analysis of each piece will not be attempted in this paper. Instead, a general survey will be made.

Samuel Barber was born in West Chester, Pennsylvania, a town on the outskirts of Philadelphia, on March 9, 1910. He was the son of Samuel Le Roy Barber and Marguerite Beatty Barber. His father came from a long line of tradesmen and professional people and was a doctor and prominent citizen in the Pennsylvanian town in which his son was born. Although no musical tendencies existed on the father's side, there were numerous accounts of musical abilities in his mother's family. Marguerite Beatty Barber was a talented pianist and the sister of the celebrated contralto, Louise Homer. At the age of six, Samuel Barber began to play the piano and a year later began to compose. Although his mother helped to write down some of his first compositions, neither she nor her husband made any attempt to develop a possible prodigy. Instead, they tried to encourage him to indulge in the activities of any normal American boy.

The problem of the present investigation was to study the soundness of guidance practices in a metropolitan high school approximately one year after the initiation of a program of guidance services. The purposes of the study were: 1. To determine to what extent the objectives of the guidance program were met. 2. To determine to what extent students, parents, and faculty considered that the guidance program had made a contribution to the school program. 3. To determine what objective measures revealed as to the effectiveness of the guidance program.

The aims of this study were: (1) to determine simultaneously by means of a micro-potometric method the rates of water and various isotopic ion effluxes from isolated onion roots; (2) to determine and compare the effects of metabolic inhibitors on both processes simultaneously; (3) to ascertain the similarity or dissimilarity of mechanisms involved with these two processes; (4) to ascertain the role of active metabolism in each of these processes; (5) to shed light on possible gearing mechanism(s) between metabolic and transport processes.

Draws a comparison between the piano variation techniques of Beethoven and Copland with reference only to the two works discussed herein, Thirty-Two Variations and Piano Variations, with the intent of gaining from these isolated examples knowledge of the changes in variation writing from Beethoven's time to the present.

The use of fantasy by the artists of the period 1250-1650 A.D. will be discussed under five categories. 1. Fantasy was used by artists in religious paintings, which served as a visual book to be viewed by the people. The artist used fantasy to show or illustrate events or miracles which could not be logically explained. 2. Fantasy was used by the artists to portray Greek and Roman mythological subjects and events. 3. Fantasy was used by the artists to present allegorical figures and ideas. 4. Fantasy was used to illustrated dreams or visions. 5. Finally, fantasy was used to create and present all kinds of fantastic creatures and monsters of the subconscious or dream world.

The purpose of this thesis is to evaluate the economic thought involved in the process of the economic evolution of Venezuela.

The purpose of the study is to determine if significant differences and relationships exist between students who enrolled late and those who enrolled on time at Tarleton State College between the years 1955-1962 inclusive. The study involves comparing the records of 325 freshman and sophomore students who registered late with those of 325 matched freshman and sophomore students who enrolled on time.

The problem of this study was to determine the relationship between the creative thinking ability of one hundred selected Negro fourth grade pupils and their parents' attitudes about rearing children.

The problem of the present study is to determine what changes will take place in certain personal and social attitudes of pre-adolescent children at the fourth- and fifth-grade levels as a result of their "having learned about the factors that underlie behavior" through a mental hygiene program utilizing "causally" oriented materials at their own level of interest and understanding.

This study made a comparative analysis of certain selected characteristics of a group of academically able male youth who persisted and those who did not persist in a five-year academic sequence in mathematics and science. Two major questions were dealt with in this study: 1. Can the persisting youth as a group be distinguished from those youth who did not persist in this academic sequence on the basis of their functioning in certain nonintellective areas? 2. Are the performances of the persisting youth on certain dimensions elevated in the same directions as are the performances of mature creatives who have been intensively studied on the same dimensions?

In this study an attempt was made to gain insight into the meaning of personality traits and how they can be arranged to build an instrument to be used for rating and selecting agents to sell life insurance.

This study was undertaken to make a comparative analysis of selected nonintellective characteristics of intellectually superior female students who persisted and those who did not persist in an Advanced Placement Program offering sequentially planned course offerings in mathematics and science. A second dimension of the study was an investigation of selected nonintellective traits to determine if the students' scores are elevated in the same direction as those of superior female adults who have been studied on essentially the same dimensions.

The problem of the study was to compare racial prejudice and self-acceptance in Negro and white college students. An attempt was made to determine the degree to which acceptance of self compared with acceptance of people of different races.

In this work, the principal concern will be with the coupling reaction and it is anticipated that the other reactions referred to above will be considered further when products of the RX-R'Li reactions are discussed.
