This thesis investigates various theorems on polynomials over the rationals, algebraic numbers, algebraic integers, and quadratic fields. The material selected in this study is more of a number theoretical aspect than that of an algebraic structural aspect. Therefore, the topics of divisibility, unique factorization, prime numbers, and the roots of certain polynomials have been chosen for primary consideration.

Resource recovery is an attractive alternative to the waste disposal problem. The chief by-product of this process, refuse derived fuel (RDF) can be co-fired in traditional coal burning facilities. The cement industry is a potential user of RDF. This study, based on a test burn done at Texas Industries Inc. in Midlothian, Texas, demonstrated the technical, environmental, and economic feasibility of using RDF fuel in a cement kiln. Technically, the cement showed no deleterious effects when RDF was substituted for coal/natural gas at 20% by Btu content. Environmentally, acid rain gases were reduced. Economically, RDF was shown to be a cost effective fuel substitute if a resource recovery facility was erected on site.

The object of this problem in lieu of thesis has been the exploration and identification of the retained two dimensional design idiom in the sculptural format of my work. (By this, I am referring to the lateral, planar quality which often continues as part of my designs.)

Abstract: Modern readers frequently perceive female characters in Victorian novels as insipid and inane, blaming the static portrayals on the angel in the house stereotype attributed to Coventry Patmore's poem of the same name. The stereotype does not accurately reflect the actual Victorian woman's life, however. Examining how the stereotype evolved and how the middle-class Mid-Victorian woman really lived provides insight into literary devices authors employed either to reinforce the angel ideal or to reconcile the ideal with the real. Wilkie Collins's portrayal of Marian Halcombe in The Woman in White features a dynamic female who has both androgynous characteristics and angel-in-the-house qualities, exemplifying one more paradox in a society riddled with contradictions.

I intended to create a body of work using a variety of media and a combination of imagery that is both subjective and objective in regards to representation. I incorporated into the work, words and phrases which are not related to the imagery. This has allowed the work to be variously interpreted. I wanted certain elements of the work to appear simultaneously very old and very new.

Many Nineteenth century writers experienced the withdrawal of God discussed by Miller in The Disappearance of God. Robert Browning and Charles Dickens present two examples of "Fra Lippo Lippi" and Great Expectations model effective alternatives to accepting God's absence. Conversely "Andrea del Sarto" accepts the void the other two heroes shun.

By the early eighteenth century, French music was tangibly influenced by the Italian style which had already permeated much of Europe. The French Cantata is symptomatic of that often disparaged influx. The cantatas of Rameau are a significant contribution to an important form. Written almost entirely in the early years of the artist's career, they hold details of his stylistic development. In the present study of Rameau's cantatas several aspects of his style are discussed as they relate both to his theoretic writings and to the various influences of the time. Examples of those stylistic elements found in the cantatas are cited and discussed. There is, as well, a comparison of the works to the poetic form standardized by Rousseau.

The biosynthesis of pyrimidines in Pseudomonas putida was investigated. In this study, pyrimidine requiring mutants were isolated by conventional mutagenesis and enrichment. The strains required exogenously supplied pyrimidines for growth and were found by enzyme assays to be deficient for the product of the pyrB gene encoding the enzyme aspartate transcarbamoylase. None of the intermediates of the pathway could supply the auxotrophic requirement of the strain; only preformed pyrimidines, metabolized via salvage pathways could suffice. Pyrimidine limitation in the mutant caused a slight but significant fifty per cent increase in expression of all the de novo biosynthetic enzymes. Pyrimidine starvation's effect on nucleotide pool levels was examined in the mutant and caused a marked swelling of the purine nucleotide pools.

An efficient two step procedure has been developed using CI GC/MS for analyzing amphetamines and related compounds. The first step allows the analysis of underivatized amphetamines with the necessary sensitivity and specificity to give spectral identification, including differentiation between methamphetamine and phentermine. The second step involves preparing a chiral derivative of the extract to identify d and 1-isomeric composition.

A description of the nature of the transition state structure for phosphoryl transfer in the cAPK reaction requires a measurement of the primary 180 isotope effect at the serine hydroxyl acceptor. Since it is difficult to obtain primary 180 isotope effect directly, the 15N/1 4N ratio of the a-amine of the C-terminal glycine in the peptide Leu Arg-Lys-Ala-Ser-Leu-Gly (when serine is phosphorylated) was used to represent on the phosphorylation at serine. 15N Glycine, ' 4N-Glycine and 180 serine were synthesized and used to synthesize two peptides, one containing 1 80-serine/' 5 N glycine and second 1 60-serine/1 4N-glycine. Methods were developed for hydrolyzing the peptides and quantitatively isolating glycine. Partitioning results suggest that catalytic rate was slow compare to substrate dissociation. The 180 primary isotope effect will be determined in the near future using the method developed herein.

This study sought to determine whether the change in the LDS Church practice of black Priesthood denial on June 8, 1978, was voluntary or was a result of external and internal pressures against the Church. Four official statements given by the First Presidency of the Church were examined using Karlyn Kohrs Campbell's seven elements of rhetorical action. It was determined that external and internal pressures from the NAACP, civil rights activists, and dissonant LDS believers, against the Church's practice of black Priesthood denial, were the motivations behind the change in Church practice.

The effects of moderate workload exercise at different pedal rates on circulatory and respiratory parameters were studied. Five subjects performed seven discontinuous constant-load cycle ergometer tests of 30 minutes duration at pedal rates of 40, 50, 60, 70, 80, 90 and 100 rpm. Oxygen uptake and carbon dioxide production were determined by standard open circuit spirometry, while heart rate was recorded by electrocardiograph. The CO₂ rebreathing procedure was administered during the exercise bout in order to determine cardiac output. Blood pressure was determined for each test, and total peripheral resistance was calculated. The findings indicate that progressive increases in pedal frequency during discontinuous constant-load cycle ergometry produce progressive increases in cardiovascular, respiratory and metabolic responses and a decrease in gross exercise mechanical efficiency. The results indicate that oxygen uptake, cardiac output, heart rate, ventilation and arterial-venous oxygen difference increases curvilinearly as pedal rate increases, possibly as a result of increases in recruitment of muscle fibers and/or muscle groups. These findings suggest that circulatory and respiratory responses are due to "central command" which sets the basic efferent response pattern. However, this effector pattern is modulated by afferent input originating from the legs during progressive increases in pedal rate.

Little scholarly analysis has been devoted to the hypothesis that antebellum Texas women generally married within their own socioeconomic (slaveholding) class, and thus had only limited choice in the selection of marriage partners. This quantitatively based investigation suggests that the popular image should be carefully qualified. This study reveals that although a majority of Texas women who married during the early 1850s chose men who had the same slaveholding status, a significant minority crossed class lines. By using marriage records of the period in correlation with information gleaned from the census, conclusions were reached. Contemporary women's diaries, letters and reminiscences were investigated, in addition to a historiography of marriage in the South, which created the background for this study.

Research estimated toxicity of refuse-derived fuel fly ash (RDF-FA) on two earthworms species, Lumbricus terrestris and Eisenia foetida. Specific objectives were to: (1) Compare their 14-day LC50s under light and dark conditions; (2) separate toxicity due to osmotic, pH and physical factors from that of heavy metal contaminants; (3) compare relative differences of artificial soil and commercial soil as exposure media for evaluating toxicity to earthworms. The 14-d LC50s for L. terrestris in dark and light were 57.0 and 48.34 % RDF-FA, and 59.25 and 41.00 % RDF-FA for E. foetida using artificial soil. All of the toxicity resulted from heavy metals within the RDF-FA. Using L. terrestris, the LC50s for artificial soil and commercial soil were 52.30 and 64.34%.

The thermocyclic fatigue behavior of the low-melting solder 43Sn/43Pb/14Bi has been investigated and compared to that of standard 60Sn/4OPb solder via metallographic analysis (using scanning electron microscopy) and evaluation of the degree of fatigue development (using a fatigue scale as a function of thermocycles). Specimens were subjected to shearing strains imposed by several hundred fatigue thermocycles. Both solder types fatigue by the same microstructural failure mechanism as described by other workers. The mechanism is characterized by a preferential coarsening of the solder joint microstructure at the region of maximum stress concentration where cracks originate.

Fifteen nonsmoking and fifteen smoking females 19 to 36 years of age were evaluated on measures of signal-to-noise ratio (SNR), jitter, shimmer, and speaking fundamental frequency (F0). The results indicated that: 1) there is a significant difference between female smokers and nonsmokers on measures of SNR, mean, and maximum F0 and, 2) there is no significant difference between female smokers and nonsmokers on measures of jitter, shimmer and minimum F0 . The SNR was found to be a powerful tool which is capable of distinguishing subtle vocal characteristics between the subject groups. It would appear that cigarette smoking may have an impact on the voice before distinct laryngeal pathologies are present.

This study assessed the effective use of pure-tone testing versus speech testing as used to predict the degree of hearing handicap experienced by an individual. Twenty-one subjects over the age of 65 were tested. Each subject was administered the following test battery: spondee threshold; a pure-tone evaluation, including air and bone conduction; Speech Perception in Noise (SPIN) test; Synthetic Sentence Identification (SSI) test; NU-6 for speech discrimination; establishment of most comfortable listening level (MCL) and loudness discomfort listening level (LDL); immittance testing including tympanograms, acoustic reflex thresholds, and reflex decay.

The purpose of the present study was to evaluate the reliability of parallel-forms of the Comprehensive Neuropsychological Screening Device (CNS). Forty-five subjects ranging in age from 16 to 69 were administered Form A and Form B of the CNS at two week intervals. Results indicated that the CNS has adequate test-retest reliability. The results suggest the applicability of using the CNS as a screening device for brain dysfunction.

This thesis is intended to give a panorama of technology in foreign language pedagogy. Although my field of study is French, the computer applications under scrutiny do not relate solely to the teaching of French. This paper begins with a criticism of the rigid listen-and-repeat language laboratory concept while tracking the rise of communicative language learning theory; follows the microprocessor revolution in language consoles; documents the development of computer-assisted instruction; showcases software evaluations of computer-assisted language learning; explores telecommunications; discusses satellite dishes and other computer peripherals; presents the results of a survey of Texas universities; and concludes with the presentation of the evolving language media center.

Concertino for Jazz Clarinet. Electric viola and Symphonic Orchestra is a composition of approximately fifteen minutes' duration, and is scored for two flutes (second doubling piccolo), two oboes, two Bb clarinets, two bassoons, four F- horns, two Bb trumpets, three trombones (third bass), two percussionists, solo Bb clarinet, solo electric viola and strings. The piece is divided into two movements; Andante and Canon. Concepts derived from jazz music are employed in, for example, harmony and improvisation in the solo parts, whereas the orchestration is mainly traditional. The piece is written for two great Swedish instrumentalists; Putte Wickman, clarinet, and Henrik Frendin, viola. Stylistically this work is difficult in the orchestral parts, since it uses concepts from two different musical styles, jazz and classical. Influences originate from such wide-ranging composers as Mozart, Stravinsky, Shostakovich and Chick Corea.

From the television advertisements made by presidential candidates from 1952 to 1976, this study analyzed the 131 advertisements that contained women. The analysis used the following descriptors: Number of Women's Roles, Age, Occupation, Marital Status, Locale, Concerns, and Status Relative to the Candidate. The results indicate that women are most likely to be shown as physically present although not speaking, in the 18 to 30 age group, belonging to a non-business atmosphere yet outside the home, and of an unknown marital status, and will not be shown in the same frame as the candidate. Womens' images in these advertisements were most commonly associated with issues involving the cost of living, taxes, pro-Nixon, and social security.

In order to become more aware of valuable characteristics that may be unique to the paintings and/or the books, I proposed to execute a body of work consisting of four sets, each set containing one painting and one book. I continued using religious icons as subject matter and the motif of the layered pentimento of the fresco as a metaphor for self-investigation.

The evolution of the State was a process which went through many stages. Analysis of the modern State tends to begin with the Enlightenment; however, Dante Alighieri, Niccolo Machiavelli, and Martin Luther each represented early phases of this evolution. The theories of these men were closely tied to their evaluation of man's nature. Their main objectives were separation of the State from the Church and the definition of the rulers obligations to his subjects. Although humanism influenced all of them to varying degrees, each developed unique views of the State. Elements of these views can be detected in more modern theorists.

For my problem-in-lieu-of-thesis, I proposed to do a collaborative installation involving three or four spaces which incorporate multi-media and audience participation. My intent was to focus on the decision-making process for creating an installation.
