Synthesis, Purification and Pharacterization of Small Mono(ADP-Ribosyl)ated Molecules in the ADP-Ribose Elongation Reaction Catalyzed by Poly(ADP-ribose)Polymerase: The ADP-ribose elongation catalyzed by poly(ADP-ribose) polymerase (PARP) [EC 2.2.2.30] has been partially characterized utilizing mono (ADP-ribosyl)ated polyamines. Arginine methyl ester (AME)-(ADP-ribose) and agmatine (AGMT)-(ADP-ribose) were synthesized enzymatically with a eukarytic mono(ADP-ribosyl) transferase and cholera toxin, respectively.
Studies on Carotenoid Biosynthesis and Carotenoproteins of Corynebacterium Poinsettiae ATCC 9682: Thin layer chromatography and high performance liquid chromatography were used to compare pigments of the wild type streptomycin resistant strain of C. poinsettiae with those of mutants derived from it. Possible biosynthetic pathways in carotenoid biosynthesis of the wild type were postulated on the basis of observed blocks in pigment synthesis.
Isolation and Characterization of Triosephosphate Isomerase Isozymes from Human Placenta: Two isozymes of triosephosphate isomerase have been isolated to homogeneity from human placenta. Triosephosphate isomerase A and triosephosphate isomerase B were compared in terms of their chemical, and biological properties.
Partial Purification and Some Properties of Lipase From Pseudomonas Aeruginosa: Purification of lipase from Pseudomonas aeruginosa (from both a washed cell suspension and crude culture supernatant as the enzyme source) was performed utilizing affinity chromatography. Affinity chromatography was carried out using n-dodecylamine bound to Sepharose 4B. Chromatography of the concentrated crude culture supernatant resulted in a 65 to 95 fold purification with 5.8% recovery. Washed cells collected from a ten hour culture suspended in water also produced enzyme. Activity of the washed cell suspension supernatant was found to be 4.5 fold higher than the activity of the culture supernatant. A thirty percent recovery was obtained using the washed cell suspension supernatant. The washed cell suspension provides a cleaner preparation for use with the dodecylamine-agarose chromatography in purifying the enzyme.
An Analysis of Adding Land Cover as a Variable to the DRASTIC Ground Water Model: This study involved a geographic information systems (GIS) approach to modeling ground water pollution potential in the Southern Edwards Aquifer Region in Texas. The DRASTIC ground water model was analyzed using two methods. First, the effects of adding land cover data to the drastic model were evaluated. In the second approach, the effects of the removal of DRASTIC variables were evaluated. Six, five, and four variable models were generated and analyzed.
A Short History of the Trombone With Emphasis on Construction Innovations and Performance Modifications From 1945 to 1970: For all of recorded history musical instruments have been a source of fascination and curiosity for man. Through a major portion of this time one instrument, the trombone, has evolved with a unique design, character, and history. The earliest trombones, called sackbuts, originally had a sliding mechanism located near the mouthpiece. In the sixteenth century this was improved by the addition of the "U-turn" which facilitated holding and playing. This construction innovation was the last major change in trombone design; the trombone of 1600 was essentially the same as the trombone of today.
Colchicine Reversibly Inhibits Electrical Activity in Arthropod Mechanoreceptors: Dendrites of cockroach tibial spine mechanoreceptors contain hundreds of free microtubules, which may have some relation to the generation of electrical activity. Deflection of a spine produces a train of action potentials. Continuous perfusion over a period of 4 hours results in no response decrement. Perfusion with 10mM colchicine reversibly inhibits the response within 5-7 minutes. Irreversible inhibition is produced by perfusion with 1mM vinblastine sulfate in perfusion solution containing 1% dimethyl sulfoxide. Deuterium oxide does not inhibit at concentrations less than 50%, nor does it counteract inhibition by 10mM colchicine. Colchicine may be affecting (1) intracellular microtubules, (2) membraneous tubulin, (3) other membrane components, or (4) axoplasmic transport of essential materials to the sensory dendrites.
An Experiment in the Deliberate Subordination of Primary Pictorial Features in Painting and Investigation of the Pictorial Interface: This study concerns the deliberate subordination in painting of thirteen art elements and principles, the primary pictorial features, and examination of the intervals between pictorial events, the pictorial interface. A written record was kept of the artist's observations and impressions during the making of ten nonobjective paintings and their later study. The artist selected five paintings as more successfully subordinating the primary pictorial features and three paintings as most successfully exhibiting the three characteristics determined for the pictorial inter face: (1) conceptual resonance, (2) ambiguity, and (3) unbiasedness. The three paintings selected as most successfully exhibiting the characteristics of the pictorial interface coincided with three of the five paintings selected as more successfully subordinating the primary pictorial features.
Cindy's Feller: an Adaptation of Cinderella: The problem with which this thesis is concerned is that of writing and directing an adaptation of the classic fairy tale, Cinderella. This study is a culmination of research on children's theatre, and the writing and producing of children's plays. The research led to the writing of the first draft of Cindy's Feller, an adaptation of Cinderella, beginning with a scenario which utilized a country-western theme. Upon completion of the first draft, the play was produced at North Texas State University during the summer of 1981. Stage directions of the play, a director's log of daily rehearsals, and an evaluation of the final productions were recorded to provide a stimulus for the writing of a final draft of Cindy's Feller and the preparation of this thesis.
Components of a Basic Wardrobe for Professional Women: The study was based on a survey of the outer garments and accessories within the wardrobes of twenty professional and business women of this vicinity. A questionnaire was used in order to obtain information concerning the wardrobes. From the results tabulated, the following concusions were reached: (1) the expenditures to provide adequate wardrobes were much more than they should have been; (2) in most cases, the distribution of garments was inadequate to meet the needs for all occasions; (3) the color selections were unrelated; and (4) the number of articles in the majority of the wardrobes was excessive. In light of the findings, the components of what the writer considers an adequate basic wardrobe have been presented and discussed.

Humanism and the Artist Raphael: a View of Renaissance History Through his Humanist Accomplishments: The thesis advances the name of Raphael Santi, the High Renaissance artist, to be included among the famous and highly esteemed Humanists of the Renaissance period. While the artistic creativity of the Renaissance is widely recognized, the creators have traditionally been viewed as mere craftsmen. In the case of Raphael Santi, his skills as a painter have proven to be a timeless medium for the immortalizing of the elevated thinking and turbulent challenges of the time period. His interests outside of painting, including archaeology and architecture, also offer strong testimony of his Humanist background and pursuits.
The Experimental Preparation of Earth Pigments of Denton County, Texas: This study is a report of the results of a series of experiments, the purposes of which were to determine: (1) what natural pigments are available in Denton County, Texas, (2) the variety, quality, and quantity of the native pigments as compared with standard commercial pigments, and (3) the suitability of these native pigments for use in the preparation of artists' colors. Since the chief interest was in the specific hues, their quality and variety, the factor of commercial possibilities was not investigated.

Kami: Kami is a two-movement composition for chamber orchestra. It is scored for two flutes; two Bb clarinets; bassoon; two F horns; Bb trumpet; bass trombone; a percussion section consisting of two performers alternating on triangle, suspended cymbal, three toms (low, medium, high), two timpani, and xylophone; piano; harp; and strings. The movements are approximately five and six minutes in duration, respectively, with a total duration of approximately eleven minutes. The title, Kami, is taken from the Japanese word for "god," and is meant to convey a sense of otherworldliness. This piece is intended as a fantasy for chamber orchestra, merging eastern and western musical influences.
Serological Reactions Among Some Species of Azotobacter: The investigation presented here was accomplished using agglutination and agar gel immunodiffusion techniques to compare Azotobacter agilis s 3at, A. chroococcum Italy AC 16, A. macrocytogenes St. M and A. vinelandii ATCC 12837. It was found that the agglutination titers differed sufficiently to allow partial identification of the four species. The homologous and heterologous systems studied by agar gel immunodiffusion tests showed that each of the four Azoto bacter species differed sufficiently in their soluble antigens to give distinct, identifiable patterns of antigen-antibody reactions on Ouchterlony agar plates. These studies also showed several antigens common to the four species tested and the resultant antigen-antibody cross reactions. The results of these investigations suggest that this approach opens a new avenue for the identification of the organisms of genus Azotobacter and perhaps, by extension, the family Azotobacteraceae.
Inferences of Sexual Orientation and Gender Role Based on Clothing and Posture: This study investigated the effect of clothing, posture, and sex of subject on inferences concerning sexual orientation and gender role. Subjects were a convenience sample of 327 students. The study wa sa 2 (masculine/feminine clothing) X 2 (masculine/feminine posture) X2 (sex of subject) between subject experimental design. Perceptions of sexual orientation were measured by a single item anchored at one end by homosexual and the other end by not homosexual.
Investigation Into the Causes for the Loss of Resolution in an Ion Chromatograpy Resin: Four mechanisms were considered as possible causes of the loss in resolution for a Dionex CG2 ion chromatography resin: 1) presence of inorganic ions strongly bound to the active sites; 2) adsorption of organic species; 3) physical alterations; and 4) chemical alterations. The instrumental analyses used to gather data were ICP, FT-IR, SEM, solid C-13 NMR and IC. Based on the results, no metal ions are bound to the resin, no organic species are held onto the resin, and no physical change was observable. The cause for the loss of resolution is a strong reduction in the number of active sites in the resin as confirmed by elemental analysis for the sulfur in the sulfonic acid present in the active sites.
The Relation Between Tissue Eosinophilia and Phospholipase B Activity in Mice Infected with Trichinella Spiralis: The number of tissue eosinophils were counted and phospholiphase B activity was assayed in the intestines of nonsensitized and sensitized and sensitized mice infected with Trichinella spiralis.

The Slide Trumpet in England From 1796 to 1900: Definitions of the trumpet, although disagreeing in certain details, generally concur in a fundamental precept: that the tube of the trumpet is cylindrical for the greater part of its length while flaring into a bell at its end. This study outlines the history of the slide trumpet in England.
A Psychological Approach to the Character of Wotan in Richard Wagner's Der Ring Des Nibelungen: The ancient Germanic god that Richard Wagner resurrected in his operatic style Der Ring des Nibelungen was worshiped and feared from Greenland to Asia Minor for 1,000 years after the birth of Christ. This thesis examines the psychological aspects of Wotan as he appears in the opera.
Induction of Interferon Messenger RNA and Expression of Cellular Oncogenes in Human Lymphoblastoid Cells: The purposes of this study was to demonstrate the induction of alpha interferon mRNA in Sendai virus-induced Namalava cells, to follow the level of alpha interferon mRNA synthesis at the transcriptional level, and to determine whether the Namalava cell line expresses the c-myc oncogene and to what degree. The amount of c-myc message deteted in Namalva cell RNA was about one-tenth that of Daudi cell RNA, whereas no difference in the amount of the c-Ha-ras message was observed between the two cell lines.
Microstructural Development of Simox and Simox Related Materials: A novel structure related to Seperation by Implanted Oxygen (SIMOX) of NiSi2/SiO2/Si is studied for two primary reasons: the importance of metal silicide and insulating oxide in IC devices and the difficulty of direct growth of crystalline silicide on amorphous substrates.
Variations of the Mouthpiece Chamber and Their Effects on the Harmonic Spectrum of the Alto Saxophone: It is the intent of this study to describe the harmonic activity that is present in the tone of the alto saxophone and to compare the spectra of selected tones when the chamber of the mouthpiece is changed in size and shape. It is hoped that the following questions might be answered: 1. What does the harmonic spectrum of the alto saxophone contain in terms of harmonic activity and the relative intensities of these harmonics? 2. What basic changes in chamber shape and size have evolved from early models? 3. Is there an appreciable change in the envelope of harmonic activity when the mouthpiece chamber is altered in size and shape? 4. Is it possible for these changes to be used to explain common terminology of the musician in describing tone qualities?
Characterization of the Specificity of DNA Uptake and Transformation by Naturally Competent Acinetobacter Calcoaceticus: Although cultures of A. calcoaceticus BD413 are naturally competent at all growth phases, genetic markers can only be successfully transformed by DNA from the genus Acinetobacter. Transformation frequencies of nearly 1.2% were obtained with pcaA mutants were incubated in liquid culture with wild-type DNA.
German singing Societies in Texas: The Germans who immigrated to Texas in the 1830s, 40s, and 50s brought with them many and varied cultural institutions which they had known and enjoyed in Europe. As soon as the initial hardships of the frontier could be overcome, they eagerly established singing societies in the Lidertafel tradition. These organizations were to have a profound impact on music in Texas from about 1850 to the time of World War I.
The Mercury Photosensitized Reactions of Some Hydocarbons: The problem was to study several hydrocarbons when they were subjected to ultraviolet light of 2536 Å in the presence of mercury vapor. It would be expected from the work of Stallings that the rupture of any tertiary hydrogen bond in the molecule would be the predominant effect. However, secondary and primary bond splitting would occur as well as some C-C bond rupturing, but these could be expected to a lesser degree than the first, since the t-hydrogen has the greatest reactivity.
Compliance-Gaining Among Anglo and Mexican-American Children: This study investigates compliance-gaining rhetoric among Anglo and Mexican-American fourth graders in three schools in north Texas. The children were asked to respond to a scenario and to give a rationale for their persuasive strategies. An analysis of interviews with 52 children indicates that although the children used some similar strategies when attempting to gain compliance from an adult, there are also some significant differences between the two cultural groups.
The Effects of Selected Work Intervals of Eccentric Exercise During a Strength Training Program: The purpose of this study was to compare the effects of six- and twelve-second time intervals of eccentric strength training among college males. Thirty-eight students were used in two experimental groups and one control group. Subjects in the two experimental groups trained three days a week for seven consecutive weeks and were required to perform two sets -of eccentric exercise with three repetitions in each set for either six- or twelve-second intervals, depending upon the experimental group assignment. Results indicated that there was a significant differ ence between the experimental groups' mean strength gain and that of the control group. There was no significant difference between the two experimental groups.
Expanded Plastics Used as Sculptural Patterns for Burn out in Ceramic Shell Molds: The purpose of this investigation was to develop a method of burning out expanded plastic patterns invested in ceramic shell molds. Technological information suggested that the procedure was not feasible because plastic expansion or gas combustion invariably spoiled the mold. However, burning out expanded plastic patterns would provide a practical method of using such materials in the sculptor's studio; combined with ceramic shells, the patterns would promote accurately detailed castings with ease and convenience.
The Reader as Rhetor: a Group Interpretation Script for the Roman Catholic Diocese of Fort Worth: This thesis examines the rhetorical dimensions of oral interpretation. A group interpretation script entitled "A New Prayer for Peace" was compiled and rehearsed. Two public performances were given to audiences in the Roman Catholic Diocese of Fort Worth (Texas). The audience members were surveyed to solicit subjective reaction.
An Annotated Translation of the British Museum, Additional 4918: Traité De La Musique Moderne, Avec Quelques Remarques Sur La Musique Ancienne Par A.D.V. (1702): The British Museum, Additional Manuscript 4918, provides an interesting insight into the sociology as well as the music of the Baroque period. This treatise was written by an unknown "music-lover," who was not a musician by profession. All that is definitely known about his identity are the initials A.D.V. that appear on the title page. The manuscript is dated 1702. In method and design this work represents the transitional character of the seventeenth and eighteenth centuries. Because the author was not a professional musician, it is important to consider the sociological aspects which influenced the writing of a treatise of this sort. A study of the development of Baroque musical treatises indicates a direct parallel with the social and political temperament of the time.
ADP-Ribosylation in a Murine Myelomonocytic Cell Line and its Association with G-CSF Induced Differentiation: In this study, ADP-ribosylation reactions in the murine myelomonocytic cell line WEHI-3BD+ were investigated.
Organelle- and Organ-Specific Isozymes of Euglena Gracilis and Catfish: Two distinct compartmentalized isozymes of aldolase and triosephosphate isomerase were examined in the photoautotrophically and heterotrophically grown green alga Euglena gracilis. A comparison of the chemical and physical properties of the isozymes was carried out. Isozymes of phosphoglucose isomerase were isolated in homogeneous form from liver and muscle tissue of the fresh water catfish. The two organ-specific isozymes were essentially identical with respect to their molecular weights but exhibited different electrophoretic and kinetic properties, and amino acid compositions.
A Comparison of Drawings Between a Group of Dyslexic Adolescents and a Group of Non-Dyslexic Adolescents: The purpose of this paper is to compare a group of adolescents with the learning disorder of dyslexia and a group of adolescents without dyslexia in regard to their ability to make realistic drawings. Subjects selected for the study were from a suburban junior high school in which a random sample was taken of both dyslexic and non-dyslexic students. Each was given three standardized drawing tasks, including a still-life drawing, a contour drawing, and a perspective drawing. The drawings were judged by five evaluators on a continuum of realistic to non-realistic. The ratings were then analyzed by the application of the Mann-Whitney U-Test, which indicated that there are no significant differences in the abilities of the two groups to render drawings realistically.
Franz Liszt: A Study of His Life and Piano Music: This study of Franz Liszt presents the Hungarian master as a figure of conflicting forces, a sort of conflicting forces, a sort of Dr. Jekyl and Mr. Hyde of music. In other words, Liszt was a dual personality. In this study of Liszt's major piano works, it will become evident that several factors were vital in the ultimate realization of these works.
The Student use of English Examination at North Texas State University, 1944-1976: This study is concerned with the history of the Student Use of English examination at North Texas State University in Denton, Texas. Conceived in 1944 and implemented in 1946, the examination serves as a measure to insure that marginal English students demonstrate a minimal proficiency in composition evidenced by a three and a half page essay written in topics related to their major fields.
