Factors Which Motivated Me to Produce as a Working Sculptor
The purpose of this project is to provide a record, much like the ones left to us by Michelangelo and Leonardo da Vinci, of the personal influences which motivated the present artist to function productively as a sculptor for a period of one semester: from September 1, 1975 through December 12, 1975. The methods involved in charting such artistic transpirations consisted of two types: a written diary, daily recorded, which indicated the progress, regression, frustration, inspiration, and perceptions which were experienced by the artist during the three-month period; and a series of personal, emotional self-enquiries.

A One-Person Exhibition: An Investigation of Problems in the Production, Selection, Presentation, and Installation
In this creative project, I investigated the problems of producing, selecting, presenting, and installing a one-person exhibition. I executed a series of 31 drawings, paintings and prints from which 21 pieces for the exhibit were selected. From the body of work executed prior to and during my graduate study, 21 pieces were included based upon the relative quality of the imagery. There were no restrictions with regard to media or size. My goal in this project was to assemble and present a coherent and harmonious exhibit in the North Texas State University art gallery.

Three Procedures for Creatively Joining Paper and Fabric Surfaces in Painting
During the last several years, my art work has evolved around a developing concept nurtured by a fascination with timeworn relics of the past centered itself around an emotional sensibility toward deteriorating fragmentary remnants of archaeological finds and relics of ancient art, predominately pottery shards and old textiles. I was intrigued and stimulated by the feeling of age and by the beauty of these worn and irregular shapes.

Gum-Bichromate Photographic Printing as Applicable to the Ceramic Process
The questions answered by this investigation were as follows: 1. Will a clay surface accept multiple emulsions and multiple development processes with little or no loss of detail? 2. Can a gum-bichromate print be accomplished using a normal 35 millimeter negative in an enlarger? 3. What is the effect of different oxides and fluxes on the emulsion? and 4. What is the effect of firing on the experimental emulsions?

Non-Heat Joining of Metals
The concern in this project was the utilization of metal joining processes which used no heat in the construction of sculpture. The problem area was motivated by an attempt to avoid some of the inherent problems and limitations incurred when welding, brazing soldering are employed. Specifically, the following questions were considered: 1) Can the non-heat joining process be utilized as a design element? 2) Does non-heat joining allow the use of lighter (30-16) gauge metal? 3) Are distortion and bracing problems reduced by use of non-heat joining processes? 4) Can more diverse metals such as aluminum, copper, brass and bronze be utilized in these processes? 5) Do these non-heat processes make allowances for manipulation of the metal prior to the construction of the sculpture?

Warp-Faced Weaving on an Architectural Scale
The impetus for this project emerged in an effort to move beyond small scaled weavings executed in neutral hues to larger pieces with more color. All of my previous work had been technically oriented, lacking in direction, and limited to neutral hues which blended well together and were readily available. I determined that the project would involve answering two basic questions: (1) could i successfully push these panels to large scale, and (2) could several of these large panels be manipulated to create an interchangeable piece that would work visually in more than one arrangements.

Photography Versus Direct Observation: An Investigation in Painting
To clarify this investigation, certain questions were formulated to guide the research. These were: 1. is the working procedure markedly different when using a photograph as a source for a work than the procedure used when working from direct observation? 2. If different, does this working procedure affect the final outcome or product? and 3. Whether the working procedure is similar or dissimilar, is the end result, i.e., the work of art, affected by the method used? That is, will the style of the works done from photographs be different from the style of those done from direct observation?

Telluric and D. C. resistivity techniques applied to the geophysical investigation of basin and range geothermal systems. Part III. The analysis of data from Grass Valley, Nevada
A detailed interpretation is presented of E-field ratio telluric, bipole-dipole resistivity mapping, and dipole-dipole resistivity data obtained in the course of geophysical exploration of the Leach Hot Springs area of Grass Valley, Nevada. Several areas are singled out as being worthy of further investigation of their geothermal potential. Comparison of the three electrical exploration techniques indicates that: the bipole-dipole resistivity mapping method is the least useful; the dipole-dipole resistivity method can be very useful, but is, for practical purposes, exceptionally expensive and difficult to interpret; the E-field ratio telluric method can be a highly successful reconnaissance technique for delineating structures and relating the resistivities of different regions within the survey area.

Characterization of sialon-type materials
Four sialon-type materials using volcanic ash as a raw material were characterized and some of their properties were determined. The M3 and M4 materials were identified as ..beta../sup 1/--Si/sub 3/N/sub 4/ sialons; their principal constituent is silicon. The M2 material was identified as a 15R-A1N polytype sialon whose principal constituent is aluminum. The M1 material is a mixture of the two types. An overview of results showing the general structural formulae and the relative order of the materials with respect to various properties as determined by the investigation is presented. It is concluded that of the materials tested, the M2 material shows the most promise as a candidate for meeting some of the current needs for high-temperature materials. It is also concluded that more research is needed in order to explain the low resistance of these materials to thermal shock since their coefficients of thermal expansion are relatively low.

Nucleation and dynamics of vortices in type-II superconductors
The one- and two-dimensional Ginzburg-Landau equations are numerically integrated in a slab geometry, which is appropriate for comparison to experimental work done on films. When two-dimensional variations become energetically favorable, a vortex is found to nucleate and move to the center of the film with the Gibbs free energy decreasing during the process. An important process by which the energy is lowered during this nucleation procedure is found to be the savings in condensation energy arising from the shrinking size of the vortex core as it moves to the center of the film. The solutions of the Ginzburg-Landau equations are used to explain anomalies observed experimentally in the tunneling characteristics of thin films of PbIn. Excellent agreement between theory and experiment is found with the Ginzburg-Landau equations correctly predicting the field at which flux would first enter the films. We then use the Clem model of an isolated vortex to model vortex nucleation and dynamics under the influence of a transport current. The entry fields predicted by the model are found to be off by almost a factor of two but have the advantage of requiring simple computer programs for their solution, while the Ginzburg-Landau solutions require substantially more numerical …

Polarized electronic spectra for the crystals of three compounds, potassium tetrabromoplatinate(II) dihydrate, tetraethylammonium hexabromodiplatinate(II), and tetra-. mu. -glycine-dimolybdenum (II) sulfate tetrahydrate
The polarized absorption spectra for K/sub 2/PtBr/sub 4/ . 2H/sub 2/O, (N(C/sub 2/H/sub 5/)/sub 4/)/sub 2/PtBr/sub 6/, and Mo/sub 2/(O/sub 2/CCH/sub 2/NH/sub 3/)/sub 4/(SO/sub 4/)/sub 2/ . 4H/sub 2/O have been recorded at 300 and 15/sup 0/K. In K/sub 2/PtBr/sub 4/ . 2H/sub 2/O the bands at 24,000 and 27,000 cm/sup -1/ in both a- and b-polarizations appear to be vibronically induced. The energy spacing of the vibrational structure was noted to be somewhat higher at 180 cm/sup -1/ than for the analogous structure of K/sub 2/PtBr/sub 4/. The presence of a Pt/sub 2/Br/sub 6//sup 2 -/ impurity gave rise to red sections, which evidently were due to the electron transfer, Pt(IV)/reverse arrow/Pt(II), occurring in c-polarization. Very weak spin-forbidden bands were observable in all three polarizations below 23,500 cm/sup -1/. In the crystal spectra of (N(C/sub 2/H/sub 5/)/sub 4/)/sub 2/Pt/sub 2/Br/sub 6/ the transitions were defined with respect to the three molecular axes of the Pt/sub 2/Br/sub 6//sup 2 -/ ion. Excited states were assigned under the D/sub 2//sub h/ point group symmetry of the ion. The delocalization of the d electrons gave rise to strongly enhanced intensities for both spin-forbidden and spin-allowed d/reverse arrow/d transitions. The M/reverse arrow/L charge-transfer …

Effects of hydrogen on the single crystalline elastic constants of niobium
A special hydriding system was designed and constructed to satisfy conditions for hydriding niobium. This system controlled the temperature and hydrogen atmosphere surrounding the niobium while ultrasonic measurements were recorded. Ultrasonic wave velocities were determined by measurement of the times for ultrasonic pulses to transit and then echo through known dimensions of test specimens. The method which was employed is commonly known as the pulse-echo-overlap method. This study confirmed the general trends of earlier investigations. In this study C' continued to decrease and C/sub 44/ continued to increase up to 4.69 atomic percent hydrogen which is the maximum concentration which has yet been examined. In the case of the niobium-hydrogen system the Snoek effect may well be a contributory factor to the decrease of C' with increasing hydrogen concentration. However, crystallographic considerations preclude this effect from contributing a concentration dependence to C/sub 44/ or B. The observation of the present work implies that other factors must also be contributing to the overall behavior.

Development of large high current density superconducting solenoid magnets for use in high energy physics experiments.
The development of a unique type of large superconducting solenoid magnet, characterized by very high current density windings and a two-phase helium tubular cooling system is described. The development of the magnet's conceptual design and the construction of two test solenoids are described. The successful test of the superconducting coil and its tubular cooling refrigeration system is presented. The safety, environmental and economic impacts of the test program on future developments in high energy physics are shown. Large solid angle particle detectors for colliding beam physics will analyze both charged and neutral particles. In many cases, these detectors will require neutral particles, such as gamma rays, to pass through the magnet coil with minimum interaction. The magnet coils must be as thin as possible. The use of superconducting windings allows one to minimize radiation thickness, while at the same time maximizing charged particle momentum resolution and saving substantial quantities of electrical energy. The results of the experimental measurements show that large high current density solenoid magnets can be made to operate at high stored energies. The superconducting magnet development described has a positive safety and environmental impact. The use of large high current density thin superconducting solenoids has been proposed …
