10 microsecond time resolution studies of Cygnus X-1

Description: Time variability analyses have been applied to data composed of event times of X-rays emitted from the binary system Cygnus X-1 to search for unique black hole signatures. The X-ray data analyzed was collected at ten microsecond time resolution or better from two instruments, the High Energy Astrophysical Observatory (HEAO) A-1 detector and the Rossi X-ray Timing Explorer (XTE) Proportional Counter Array (PCA). HEAO A-1 and RXTE/PCA collected data from 1977--79 and from 1996 on with energy sens… more

The addition of disilanes to cumulenes

Description: The syntheses of silicon-containing compounds and the studies of their rearrangements have been active research areas in the Barton research group. Previously, the addition of disilanes to acetylenes was studied in the group and an intramolecular 2S + 2A mechanism has been proposed. In this thesis, the work is focused on the addition of disilanes to cumulenes. The syntheses of the precursors are discussed and the possible mechanisms for their thermal, photochemical and catalytic rearrangements … more

AIDS Preventative Behavior Among Taiwanese University Students

Description: This study used the Health Belief Model to examine the predictors of AIDS preventive behavior. The independent variables were the variables of individual perception, modifying factors (psychological variables), and likelihood variables. The respondents, the Taiwanese students of the University of North Texas, were influenced both by Chinese sexuality and Western values in their AIDS-risk behavior. The results revealed that 90% of the respondents were misinformed on the availability of AIDS vacc… more

An Analysis of the Attempted Amalgamation of Western and Chinese Musical Elements in Huang Anlun's Piano Concerto in G Minor, Opus 25b, a Lecture Recital, Together with Three Recitals of Selected Works by Bach, Beethoven, Chopin, Liszt, Mozart, Schubert, and Schumann

Description: While China possesses one of the world's richest musical heritages, it remained unaffected by Western music until early in this century. Subsequently, there was a movement of nationalism in music approximately three decades after the introduction of Western music. This movement, aimed at utilizing Western compositional techniques to create musical works that still would be uniquely Chinese, continues even today. Huang's piano concerto was written in 1982, just a few years after the Cultural Rev… more

Anion Exchange and Competition in Layered Double Hydroxides

Description: Exchange reactions of anions, especially ferrocyanide and carbonate, with layered double hydroxides (LDHs) were investigated in relation to the origin of life on the early Earth. The effect on ferrocyanide exchange of concentration, pH, reaction time and cations are discussed. It was found that there were two different kinds of ferrocyanide species: one was that intercalated into the layered structure, occupying a site of D symmetry within the LDHs, while in the other, the ferrocyanide group re… more

Anomalous loss of DT alpha particles in the Tokamak Fusion Test Reactor

Description: An escaping alpha collector probe has been developed for TFTR`s DT phase. Energy distributions of escaping alphas have been determined by measuring the range of {alpha}-particles implanted into nickel foils located within the alpha collector. Results at 1.0 MA of plasma current are in good agreement with predictions for first orbit alpha loss. Results at 1.8 MA, however, show a significant anomalous loss of partially thermalized alphas (in addition to the expected first orbit loss), which is no… more

Assessing the Psychological Impact of Fertility Treatment

Description: This controlled descriptive study was designed to investigate the psychological status of couples who are engaged in advanced fertility treatments. A battery of psychological test instruments, including the Millon Behavioral Health Inventory (MBHI), the Health Attribution Test (HAT), the Beck Depression Inventory (BDI), the Beck Anxiety Inventory (BAI), and the Marlowe-Crowne Social Desirability Scale (MCSDS), was used to measure psychological variables that have been shown in the infertility r… more

Assessment and Treatment of Object Mouthing in the Classroom

Description: The object mouthing of a developmentally delayed 8-year-old girl was assessed and treated in a classroom setting. Two pretreatment assessments were conducted: A functional analysis indicated that object mouthing occurred across test conditions and persisted in the absence of social contingencies, and assessment of stimulus preference identified reinforcers to be used during treatments. Based on assessment outcomes, two treatments were implemented. Noncontingent sensory reinforcement was impleme… more

Assessment of Changes in Aquatic Macrophyte Occurrence Following Introduction of Triploid Grass Carp in a North Texas Reservoir

Description: The objectives of this project were to measure changes in frequency of occurrence of submerged macrophytes over the first two growing seasons following stocking with triploid grass carp at two fish per acre and to measure differences in macrophyte biomass between areas excluded from herbivory and adjacent control sites after 16 months following establishment of exclosures. The project also seeks to measure concentrations of fluridone following the herbicide treatment, and to compare two methods… more

Assessment of Malingering in a Jail Referral Population : Screening and Comprehensive Evaluation

Description: Psychological assessment of mentally disordered offenders requires a systematic consideration of response styles, including malingering and defensiveness. Important components of these evaluations are standardized diagnostic interviews. However, the ability of offenders to feign mental disorders on such measures to achieve such external incentives as treatment, placement on safer units, or possible release from jail remains uninvestigated. With a known-groups comparison with the data from the S… more

Atomic holography with electrons and x-rays: Theoretical and experimental studies

Description: Gabor first proposed holography in 1948 as a means to experimentally record the amplitude and phase of scattered wavefronts, relative to a direct unscattered wave, and to use such a {open_quotes}hologram{close_quotes} to directly image atomic structure. But imaging at atomic resolution has not yet been possible in the way he proposed. Much more recently, Szoeke in 1986 noted that photoexcited atoms can emit photoelectron of fluorescent x-ray wavefronts that are scattered by neighboring atoms, t… more

Awen, Barddas, and the Age of Blake

Description: Studies of William Blake's poetry have historically paid little attention to the Welsh literary context of his time, especially the bardic lore (barddas), in spite of the fact that he considered himselfto be a bard and created an epic cosmos in which the bardic had exalted status. Of particular importance is the Welsh concept of the awen, which can be thought of as "the muse," but which must not be limited to the Greek understanding of the term For the Welsh, the awen had to do with the Christi… more

Biology and Energetics of Tropisternus Lateralis Nimbatus (SAY) (Coleoptera: Hydrophilidae) in a Playa on the Southern High Plains of Texas and Aquatic Coleoptera Diversity from Seven Playas on the Southern High Plains of Texas

Description: A study of the biology of Tropisternus lateralis, a hydrophilid beetle, was conducted during the flood period of a single playa on the Southern High Plains of Texas from early June 1995 through early September 1995. Mechanism of colonization, tolerance/avoidance to drought, larval density, and secondary production were analyzed. T. lateralis colonized playas from surrounding aquatic habitats and avoided drought through aerial dispersion. Once in the playa, larval density increased over time. Se… more
