Grimaldi

Description: Grimaldi is a synesthetic work composed of aural and visual media including noise, tone, electronic devices, lighting and theatrical events. It is designed for solo saxophone with an accompanying ensemble of eight wind instruments and four percussion. The most important aspect of the piece is its texture, which consists of constantly changing and interacting aural and visual events. The compositional process of Grimaldi began with the selection of a form constructed of two equal arches of unequal subdivision, and the designation of texture for each section. After these selections were made, the theatrical elements were selected, based on a traditional story about the clown Joseph Grimaldi (1787-1836). By gradually refining these general selections into specific notation, and by considering them as a whole rather than individually, consistent relationships were maintained.

Synthesis and characterization of metal--metal bonded dimers of tantalum and tungsten

Description: A search for innovative synthetic routes to new metal-metal bonded metal-halide clusters resulted in isolation of two completely independent dimeric species. The syntheses and characterizations of Ta/sub 2/X/sub 6/(SC/sub 4/H/sub 8/)/sub 3/ (X = Cl, Br) and ((n-C/sub 3/H/sub 7/)/sub 4/N)/sub 2/(W/sub 2/Br/sub 9/) followed entirely different experimental routes, yet occasionally similar properties linked the two projects.

A Study Combining Stoneware and Found Objects

Description: The intention of this study is to examine the relationship between fired clay and certain found objects. Working from the assumption that clay, being a natural substance, shares a common ground with certain other natural substances, such as wood, hemp, rock, etc., a primary aspect of the investigation consists of discovering successful combinations of these materials. In each design two subordinate problems were encountered. These were (1) determining the best means of combining and preserving objects in a semi-permanent state and (2) ascertaining whether the thrown form is by itself visually satisfying or if it would be improved by distortion.

Molecular beam kinetics

Description: The design of a crossed molecular beam ''supermachine'' for neutral-- neutral collisions is discussed. The universal electron bombardment ionizer, mass filter, and ion detection system of the detector, the supersonic nozzle sources, the differential pumping arrangement for the sources and detector, the time-of-flight detection of scattered products, and the overall configuration of the apparatus are described. The elastic scattering of two systems, CH$sub 4$ + Ar and NH$sub 3$ + Ar, has been measured using the supermachine with two supersonic nozzle sources. The rainbow structure and the interference oscillations are seen in each system. The best fit to the data was found using a Morse--Spline--Van der Waals (MSV) potential. The three potential parameters epsilon, r/sub m/, and $beta$ were found to be 2.20(+-0.04) x 10$sup -14$ ergs, 3.82(+-0.04)A, and 7.05 +- 0.20 for CH$sub 4$ + Ar, and 2.21(+-0.04) x 10$sup - 14$ ergs 3.93 (+-0.05)A, and 8.45 +- 0.30 for NH$sub 3$ + Ar. A new phenomenon in crossed molecular beams of condensation of a molecule on a cluster to form a complex was observed. A bromine molecule condensed on clusters of chlorine (Cl$sub 2$)/sub chi/ and ammonia (NH$sub 3$)/sub chi/. The value of chi for measurements in these experiments ranges from 7 to 40 for chlorine clusters and from 10 to 70 ammonia clusters. (auth)

CARBON-13 NMR STUDIES OF LIQUID CRYSTALS

Description: High resolution, proton decoupled {sup 13}C nmr are observed for a series of neat nematic liquid crystals, the p-alkoxyazoxybenzenes, and a smectic-A liquid crystal, diethylazoxydibenzoate in a magnetic field of 23 kG. The (uniaxial) order parameters S = <P{sub 2}(cos{theta})> are found to be about 0.4 and 0.9 for the nematic and smectic-A phase respectively at the clearing points. The order parameter increases with decreasing temperature in the nematic phase but is constant, or nearly so, with temperature in the smectic-A phase. In the nematic series studied, the ordering exhibits an even-odd alternation along the series and qualitative agreement with a recent theory due to Marcelja is found. In both phases, the spectra show that the molecule rotates rapidly about its long axis. Tentative conclusions about molecular conformational motion and {sup 14}N spin relaxation are presented for both nematic and smectic-A phases. In the smectic-A phase, the sample is rotated about an axis perpendicular to H{sub 0} and the resulting spectra are discussed. The theory of observed chemical shifts in liquid crystals is treated in an appendix. Equations are derived which relate the nmr spectra of liquid-crystals to the order parameters. A model for the smectic-C phase due to Luz and Meiboom and Doane is described and lineshapes are determined on the basis of this model for special cases. Experiments on smectic-C liquid crystals are currently underway for comparison with the theory. Also treated in an appendix is the dependence of the order parameters on the molecular potential which give rise to the various degrees of order in the different liquid crystalline phases. To a good approximation the functional dependence of the order parameters on the molecular potential is shown to be a simple one in the limit of small tilt angle in the smectic-C phase.

The Effects of Birth Order and Family Size on Children's Locus of Control

Description: The present study was concerned with investigating children's generalized locus of control of reinforcement and its possible relationship to the demographic variables of birth order and family size. The sample consisted of 93 school children in Grades 6, 7, and 8. The analysis of data was by a 2 x 3 factorial design. Results indicated no significant differences in the generalized locus of control orientations of first-born, intermediate-born, and youngest children. Results also indicated that children of these different birth order positions from small families and from large families did not differ significantly in their generalized locus of control orientation. A correlational study of the data showed that the children's locus of control orientations were unrelated to sex differences.

A Comparative Analysis of the Need for Various Knowledge and Skills in Plastics as Viewed by Texas High School Plastic Teachers and Texas Plastics Industries

Description: This was a comparative study in which Texas teachers of industrial plastics and the employers of Texas plastic industries were surveyed in order to evaluate the need for various knowledge and skills of the plastics industry. The respondents believed that basic knowledge of plastics was much needed, and knowledge of the thermoplastic family is of more importance than of the thermoset family. It was also concluded that knowledge of demonstration skills is of only average or lesser importance than knowledge of other areas.

Fibre-Tip Pen Line Techniques

Description: In selecting a thesis project, my interest and experience with fibre-tip pen drawings suggested that further investigations would be profitable. Fibre-tip pens provide a fast and convenient means to draw under outdoor conditions. The pens make dense black and consistent lines at whatever speed they are moved. The ink supply is automatic; not requiring a separate container for dipping and not requiring cleaning. Fibre-tip pens designed to make lines of different widths are commercially available at low cost.

The Detection of Poliovirus in Denton Sewage by Immunofluorescence and Immunodiffusion Techniques

Description: Several final sewage effluents from the Denton Disposal Plant were demonstrated to contain Poliovirus types II and III. Pleated encapsulated filters at pH3.5 enhanced the recovery of the Poliovirus at a higher tier in comparison with nitrocellulose filter (Millipore) and glass fiber filter of pore size 0.45u. This thesis explores problems that face us today in our quest to eliminate viral pathogens from the natural and waste water needed for human, domestic, and industrial consumption. Preliminary experiments concern the use of immunofluorescence, and immunodiffusion techniques as a means of poliovirus identification, which invariably suggests that these techniques may be useful as rapid screening procedures of water samples for presence of potentially pathogenic viruses.

The Journalist as Legislator

Description: The focus of the study is the way which members of the press corps in the Texas Capitol influence policy-making through their friendships with legislators and through the news stories which they write. Methods of study included questionnaires to reporters and to legislators, interviews with members of both groups, and review of news stories written about the regular session of the 64th Texas Legislature. Respondents reported that journalists were used as "expert consultants" in legislative strategy as well as in policy content areas. While informal relationships were found to have an impact on policy, published news stories were perceived as having greater influence.
