The Use of Symbolic Imagery Through the Decorative Qualities of Majolica
For the purpose of this study I intended to use Majolica to allow me both more flexibility in the physical act of decorating my ceramic work, as well as the opportunity for the expansion of my selection of symbols. During this investigation the following questions were addressed: 1. Was the color range attainable with Majolica relevant to my work? 2. Was my chosen imagery complemented by the special properties of Majolica. 3. Did the textural possibilities of Majolica benefit my work?

Art by the Yard: Exploring Narrative Drawings
I am interested, both from a personal standpoint and from a cultural perspective, in pursuing the meaning of thes eimages singly and as they combine with others. In turn, the results, I hope, will lead to the discovery of more images for my image encyclopedia. After this introduction subsequent chapters will explore my reasons for the combinations of images I choose and will place the finished drawings in their contemporary art context. My goal will be to note the changing meanings of the objects as they interact serially.

Concept Vs. Intuition: A Study Into the Personal Understanding of Images
I was curious as to what my work was about and what images were important to me. There had to be a reason why I was driven to do what I did, whether it was a conscious, conceptual purpose or a subconscious, intuitive reason. The problem of this investigation was to discover which of these I used in the creation of my images or whether I used both.

The Effect of Paper Supports as Aesthetic Choices Made in the Oil Painting Process
I believe that an artist needs a mechanism(s) built into his or her working method out of which the greatest number of options may arise. I suggested that, for me, painting on paper could be one such mechanism. I wanted to pursue paper as a viable surface on which to paint and discover to what extent it would influence my choices in the working process.

The Influence of the Exploration of Scale on the Responses Made in Sculpture
The purpose of this problem-in-lieu of thesis is to explore the effect of scale in my sculpture, on me as an artist as well as the viewer. My work addressed the following questions: 1. Can smaller-than-life-size sculpture communicate with the same intensity as my previous life-size work? 2. How does scale affect the ability of the work to communicate ideas and feelings? 3. Can the sculpture be as confrontational without occupying space as we do? 4. Does a larger-than-life-size piece gain intensity in any of these questions due to its scale? 5. How does scale affect my feelings toward the work and my method of working?

The Imagery of "Man": An Analysis of Ten Paintings and Their Related Imagery
The Isle of Man and Southeast Texas both display unique aspects of their geographical localities. In many ways they share similar attributes. I feel strongly that we are a product of our past and of our surroundings. So what type of imagery can be dealt with as a personal icon to link the two diverse places of my past and present?

One-Sitting Paintings
Even Though I already did paint fairly rapidly, I felt I had a tendency to let the painting in progress sit too long in between times spent working on it. I also felt that I was spending too much time stepping back away from the work to look at it and was milling around the studio sometimes needlessly. Thus I became intrigued with the idea of doing a painting in one block of time. The purpose of this investigation was to explore and study the possibilities generated by a series of "one-sitting" paintings. I defined one-sitting painting as a painting which proceeded from beginning to end without a significant break, meaning that it could take anywhere from four to sixteen hours to complete.

Masks and Nature
The intention of my mask-making was to present a body of work that visually captured my many encounters with spiritual presences in nature. From my perspective, these spiritual presences can be described most effectively as Platonic ideals, or the blueprints from which all physical forms are derived. These spirits are, therefore, the life breath and animating force behind the material world. I wanted to transcend the mere physical manifestations of nature and create in the masks a primary vehicle or conduit for the spiritual presences that I sensed in nature.

Building a Personal History With Layered Symbolic Images
Since I was a young child, I have had a deep interest in all facets of the cultures of early humans and more modern primitive peoples-- in particular, their art and their mythology. It was my proposal, therefore, to combine these interests with the styles of my earlier works by using images drawn from the various aspects of my ancestry in several pieces of work in which the layering of those images-- similar to the layers of my heritage-- was used. My choices were limited to a set number of images listed in a "dictionary of symbols." I continued to engage in on-going research of these symbols to determine if there were relationships in their meanings between the various cultural elements of my ancestry.

Developing an Efficient One-Man Potter's Studio
The problem I proposed to explore involved making changes in personal work practices in the studio as well as studio organization. Using advice and practices that I have gleaned over the past few years, I made changes in the areas of studio organization, wheel production, and the glaze decoration process with the goal of adapting to a limited studio space and becoming more productive.

An Investigation of Mexican Gravesites in Nuevo Laredo, Mexico and Laredo, Texas
My work already shared some of the characteristics of the gravesites that I proposed to study. They were similar in that they both attempted to integrate sacred and profane imagery. Both called attention to personal events and related these events to a larger scheme. Finally, both were involved with the creation of objects of veneration according to personal edicts, but in relation to already established mythologies. I proposed to create a body of work based on the information gathered from the investigation of three predominantly Mexican graveyards-- one in Nuevo Laredo, Mexico, and two outside of Laredo, Texas.

An Analysis of Verticality and Architectural Reference in the Presentation of Figurative Sculpture
The purpose of this study was to analyze the physical issues of verticality and architectural reference in the presentation of my figurative sculpture and to determine how these issues affect me as viewer. In this analysis, the term architectural reference refers to the fundamental structural elements historically associated with architecture, such as column, pylon, pilaster, pyramid, elevated platform, and bilateral symmetry. The term does not address broader architectural concepts such as spatial organization, circulation, or shelter.

Mixed-Media Installation Concerns
As I proceeded with my work within this format, I encountered some concerns that dealt with value judgement involving the presentation of an effective installation of this type. The challenge for me was to form a union between the images in my mind and the combination of materials that I chose to use. I wanted the viewer to be conscious of the entire space, as one experience made up of numerous elements.

The Development of Non-Clay Materials With the Expression of Personal Imagery
My creative project was to expand the depth at which non-clay materials such as wood and metal (brought, found, or otherwise acquired) were successfully blended with clay, both physically and visually. Also, imagery--so essential to the narrative quality of the work-- was to be expanded upon to provide a constant freshness that avoided repetition or variation for its own sake.

Theoretical studies of non-Newtonian and Newtonian fluid flow through porous media
A comprehensive theoretical study has been carried out on the flow behavior of both single and multiple phase non-Newtonian fluids in porous media. This work is divided into three parts: development of numerical and analytical solutions; theoretical studies of transient flow of non-Newtonian fluids in porous media; and applications of well test analysis and displacement efficiency evaluation to field problems. A fully implicit, integral finite difference model has been developed for simulation of non-Newtonian and Newtonian fluid flow through porous media. Several commonly-used rheological models of power-law and Bingham plastic non-Newtonian fluids have been incorporated in the simulator. A Buckley-Leverett type analytical solution for one-dimensional, immiscible displacement involving non-Newtonian fluids in porous media has been developed. An integral method is also presented for the study of transient flow of Bingham fluids in porous media. In addition, two well test analysis methods have been developed for analyzing pressure transient tests of power-law and Bingham fluids, respectively. Applications are included to demonstrate this new technology. The physical mechanisms involved in immiscible displacement with non-Newtonian fluids in porous media have been studied using the Buckley-Leverett type analytical solution. In another study, an idealized fracture model has been used to obtain some insights into …

Studies of DNA supercoiling in vivo and in vitro
This thesis describes a number of diverse experiments whose common theme is to elaborate some aspect of DNA supercoiling. The torsion elastic constant of DNA is measure as a function of superhelix density using the technique of picosecond Time Resolved Fluorescence Polarization Anisotropy (FPA) of intercalated ethidium bromide. The results agree with theories which predict that the anisotropy decay should vary with the square root of the relative viscosity. This experiment furthermore demonstrates a sensitivity of FPA to a change in torsion elastic constant of less than 10%. A number of covalently closed DNA samples, ranging in superhelix density from = {minus}0.123 to {plus}0.042, are then examined. A novel method for measuring changes in local supercoiling on a large PNA molecule which is sensitive to changes in supercoiling of regions of chromosomal DNA as short as 1 kilobase in length is presented. Study of chromosomal supercoiling regulating anaerobic gene expression in the facultative photosynthetic bacterium, Rhodobacter capsulatus showed that no stable change in chromosomal supercoiling upon a shift from aerobic respiratory growth to anaerobic photosynthetic conditions. Studies to detect transient changes in DNA supercoiling indicate that DNA downstream from heavily transcribed genes for the photosynthetic reaction center are relaxed or …

Transverse liquid fuel jet breakup, burning, and ignition
An analytical/numerical study of the breakup, burning, and ignition of liquid fuels injected transversely into a hot air stream is conducted. The non-reacting liquid jet breakup location is determined by the local sonic point criterion first proposed by Schetz, et al. (1980). Two models, one employing analysis of an elliptical jet cross-section and the other employing a two-dimensional blunt body to represent the transverse jet, have been used for sonic point calculations. An auxiliary criterion based on surface tension stability is used as a separate means of determining the breakup location. For the reacting liquid jet problem, a diffusion flame supported by a one-step chemical reaction within the gaseous boundary layer is solved along the ellipse surface in subsonic crossflow. Typical flame structures and concentration profiles have been calculated for various locations along the jet cross-section as a function of upstream Mach numbers. The integrated reaction rate along the jet cross-section is used to predict ignition position, which is found to be situated near the stagnation point. While a multi-step reaction is needed to represent the ignition process more accurately, the present calculation does yield reasonable predictions concerning ignition along a curved surface.

Quantum Monte Carlo methods and lithium cluster properties
Properties of small lithium clusters with sizes ranging from n = 1 to 5 atoms were investigated using quantum Monte Carlo (QMC) methods. Cluster geometries were found from complete active space self consistent field (CASSCF) calculations. A detailed development of the QMC method leading to the variational QMC (V-QMC) and diffusion QMC (D-QMC) methods is shown. The many-body aspect of electron correlation is introduced into the QMC importance sampling electron-electron correlation functions by using density dependent parameters, and are shown to increase the amount of correlation energy obtained in V-QMC calculations. A detailed analysis of D-QMC time-step bias is made and is found to be at least linear with respect to the time-step. The D-QMC calculations determined the lithium cluster ionization potentials to be 0.1982(14) [0.1981], 0.1895(9) [0.1874(4)], 0.1530(34) [0.1599(73)], 0.1664(37) [0.1724(110)], 0.1613(43) [0.1675(110)] Hartrees for lithium clusters n = 1 through 5, respectively; in good agreement with experimental results shown in the brackets. Also, the binding energies per atom was computed to be 0.0177(8) [0.0203(12)], 0.0188(10) [0.0220(21)], 0.0247(8) [0.0310(12)], 0.0253(8) [0.0351(8)] Hartrees for lithium clusters n = 2 through 5, respectively. The lithium cluster one-electron density is shown to have charge concentrations corresponding to nonnuclear attractors. The overall shape …
