The adiabatic single crystalline elastic constants of six Mg(Cu, Zn)/sub 2/ cubic Laves phases have been determined by the ultrasonic pulse-echo technique over the compositional range 10 to 50 mol % MgZn/sub 2/ and over the temperature range 4.2 to 300/sup 0/K. In addition the elastic constants of the hexagonal MgZn/sub 2/ Laves phase were measured as a function of temperature. A minimum exists in the compositional dependence of the cubic Mg(Cu, Zn)/sub 2/ phase at 20 mol % MgZn/sub 2/ for all three directly measured values and the anisotropy ratio shows a maximum at the same composition. These phenomena may be related to the fact that their Fermi surface touches the (311) faces of the Brillouin zones at this composition. The various energy contributions to the elastic shear constants were considered and it was concluded that the Fermi energy has to be included to achieve satisfactory agreement between the calculated and measured elastic constants. The Debye temperatures were calculated and were found to decrease at low zinc contents and then increase at compositions above 20 mol % MgZn/sub 2/ for the cubic Mg(Cu, Zn)/sub 2/ phase. The initial decrease is probably due to the substitution of the heavier zinc …

The particles in an accelerator interact with one another by electromagnetic forces and are held together by external focusing forces. Such a many-body system has a large number of transverse modes of oscillation (plasma oscillations) that can be excited at characteristic frequencies by errors in the external guide field. In Part I we examine one mode of oscillation in detail, namely the quadrupole mode that is excited in uniformly charged beams by gradient errors. We derive self-consistent equations of motion for the beam envelope and solve these equations for the case in which the space-charge force is much less than the external focusing force, i.e., for strong-focusing synchrotrons. We find that the resonance intensity is shifted from the value predicted by the usual transverse incoherent space-charge limit; moreover, because the space-charge force depends on the shape and size of the beam, the beam growth in always limited. For gradient errors of the magnitude normally present in strong-focusing synchrotrons, the increase in beam size is small provided the beam parameters are properly chosen; otherwise the growth may be large. Thus gradient errors need not impose a limit on the number of particles that can be accelerated. In Part II we examine …

This report is about the Classical Dynamics of Triatomic Systems which is divided into three parts.

Throughout the period following Pearl Harbor, as one crisis in Japanese-American relations followed another, the American public opinion was divided. Some newspapers and personalities feared that there would be war over the San Francisco school board crisis, while others believed that talk of war was ridiculous. Partisan politics often affected the course of affairs on the Japanese question.

The problem of this study was to compare arithmetic performance scores of pupils who had been presented tape-recorded instruction with arithmetic performance scores of pupils who had received the same instruction by means of traditional teaching methods.

"The purpose of this study is to examine the impact of the medicare law on a particular hospital: Flow Memorial Hospital, Denton, Texas. The scope of this study is limited to an analysis of changes in hospital car at Flow Memorial Hospital resulting from medicare. These changes are examined on the basis of 1. number of patients and days of care; 2. hospital services by department; 3. the means of payment; and 4. social characteristics of the aged patient group. A detailed examination of aged patient care was made for the fiscal years 1966 and 1967. The 1966 year was the year immediately preceding medicare. The 1967 year was the first year of medicare. Longer time periods were used where the data were available and pertinent."-- leaf 1.

Four objectives guided the research and writing of this thesis. First, there was an attempt to identify and establish specific educational goals for a group interpretation production. Second, there was an effort to describe certain procedures for selecting, adapting, arranging, and presenting a piece of literature to an audience through a group interpretation performance. Third, this thesis attempted to relate the three modes of group interpretation—Choric Interpretation, Readers Theatre, and Chamber Theatre—as a single art form. Fourth, there has been an attempt to suggest specific evaluative criteria and evaluation sheets for group interpretation performances.

The purpose of this study is to analyze the patterns and magnitudes of per capita expenditures and revenue collections in selected metropolitan areas in an attempt to explain variations in expenditures between metropolitan areas.

The object of this study was to compile a list of solo literature for beginning college voice students and analyze these solos for pedagogical and performance purposes. There is no lack of printed material on the subjects of singing and voice culture. But it is not readily accessible to teachers since it is extremely diversified and rather diffusely distributed throughout a variety of sources, such as books, periodicals, and scientific papers. Several lists and books containing songs for beginners have been compiled.

There is evidence in Steinbeck's works of anti-intellectualism which is expressed by a somewhat maudlin handling of human emotions,and by a doggedly persistent attack on various intellectual types. This attitude is further revealed in Steinbeck's personal life by his abstention from any literary coteries or universities and his adamant refusal to discuss his life and works or offer his considerable talent to any institution of higher learning.

Computers are used in the music field for generation of sound, for composing music, for analysis of music, and for musicological applications, such as cataloguing a bibliography of music literature. These areas are relatively new aspects of computer usage, and research is being conducted to stay abreast of current technological advancements. Avant-garde composers are challenged by new advances in music. Computer-generated music is one of the new trends, but the composer is usually limited in the use of the medium for two reasons: there are no computers to which he may have access, and/or there is not enough knowledge about computer-generated music. The composer sometimes feels that he must have vast knowledge of the computer before he can attempt to use it in musical composition; however, a limited amount of investigation of computer-generated music has shown that methods can be codified to the point where great technical knowledge is not required of the composer.

This thesis presents a comparison of the ideas of two philosopher-psychologists, James and Bergson, and studies the theory and techniques in the three works of fiction that comprise "The Aviary Trio."

The purpose of this study is to trace the development of a practically extinct woodwind instrument, the basset horn, and its use by composers as both a solo and an orchestral instrument. The first chapter concerns the development of the basset horn from the earliest imperfect specimen to the modern-day instrument. The second chapter deals with the physical characteristics that are peculiar to the instrument. The third chapter discusses the literature and musical history of the basset horn. An appendix provides a comprehensive listing of literature for the instrument.

This study is concerned with the nature of the relatively unusual bonding which occurs in organolithium compounds as a direct result of the oligomerization and possible explanations for that bonding.

The purpose of this study was to compare three different approaches to the counselor practicum—-or campus practicum, an off-campus practicum, and a role-playing practicum—-with regard to the changes in attitudes, personality, and effectiveness of counseling behavior of counselor trainees produced by each type of practicum.

Shakespeare's Cleopatra is a character of magnificent aspect, a puzzling paradox of magnetic intensity, an intensified diversity unmatched by any other Cleopatra in literary history. Although she was not his invention, Shakespeare made of her a living woman, believable in spite of her incredulous behavior.
