Vestibular Responsiveness In Normal- And In Impaired-Hearing Children., Nancy Mixon Hillman Jan 1981

Vestibular Responsiveness In Normal- And In Impaired-Hearing Children., Nancy Mixon Hillman

LSU Historical Dissertations and Theses

Vestibular responsiveness of 90 normal- and of 31 impaired-hearing children from 4 through 16 years of age was investigated using a modified Barany-chair test to provide horizontal angular acceleratory stimuli to the semi-circular canals and a parallel swing to provide alternating horizontal linear acceleratory stimuli to the otolithic end organs. Children's eye movements behind a sleep mask in response to vestibulo-ocular reflexes initiated by the angular and linear accelerations were recorded via electronystagmography and telemetry. Mean frequency, amplitude, and slow phase velocity of primary postrotatory nystagmus and presence or absence and latency of secondary per- and postrotatory nystagmus were obtained …


Methanogenesis In Marine Sediments Of The Mississippi River Delta., Leonard Alan Hook Jan 1981

Methanogenesis In Marine Sediments Of The Mississippi River Delta., Leonard Alan Hook

LSU Historical Dissertations and Theses

The highest most probable numbers (MPNs) of methanogens (1.18 x 10('6) cells per 100 g sediment, dry weight) and sulfate-reducers (0.31 x 10('6) cells per 100 g sediment, dry weight) in unstable, gas-rich, Mississippi River delta sediments occurred together in samples taken 0.2m below the sediment-water interface. The presence of sulfate-reducers was directly related to dissolved sulfate in the interstitial water. Dissolved methane in the sediments was inversely related to the presence of sulfate-reducing bacteria. Methanogens and sulfate-reducers were recovered from maximum depths of 29.3 and 75.0 m, respectively. Two horizons of dissolved sulfate, with peaks of sulfate-reducer MPNs, indicated …


The Forgiving Landscape: The Poetry Of William Stafford., Malovika Mukerji Jan 1981

The Forgiving Landscape: The Poetry Of William Stafford., Malovika Mukerji

LSU Historical Dissertations and Theses

There is a wholeness and a sanity in William Stafford's vision that arises out of his allegiance to the authentic elements of our experience. These elements include the vital but continually imperiled wilderness, the human landscape of the past comprised of family, friends, and lovers, and the eternal and inescapable rhythms of time, death, mutability, and terror. In his own words, Stafford is seeking to embody in his work "the unanalyzed impressions of holiness" that the world thrusts at him. By temperament and by choice, Stafford is alienated from the so-called confessional school of poetry. Instead, he writes in the …

Faraday Rotation Investigations Of Surface Space-Charge Layers In Metal - Oxide - Semiconductor (Mos) Systems., Gary L. Wallace

LSU Historical Dissertations and Theses

The free carrier Faraday effect is considered in both the Drude model and the Appel-Overhauser model for inversion layer electrons at the SiO(,2)-Si interface. An exact algebraic relation between the photon, cyclotron, collision and plasma frequencies is obtained which must be satisfied in order to achieve null rotation and null ellipticity for a single pass of the electromagnetic wave in the Drude model. Plots of the rotation versus angular photon frequency in the Appel-Overhauser model for various values of the electron-electron (e-e) scattering time (tau)(,e) are presented. These plots show that Faraday rotation measurements are a possible way of determining …

The Austrian Problem Of Language And Peter Handke: A Documentation., Donald Russell Bailey Jan 1981

The Austrian Problem Of Language And Peter Handke: A Documentation., Donald Russell Bailey

LSU Historical Dissertations and Theses

Linguistic skepticism and the resultant awareness of the limits of language can be traced back to Hamann, Herder, and Humboldt, through Romanticism and French Symbolism, up to modern times. What has come to be called the crisis of language (Sprachkrise) can be viewed as one segment of a broader, multi-media phenomenon. The intensity of this crisis is concentrated in Austro-Hungary in the waning days of the Habsburg Monarchy. From this time forward supersensitivity to language remains a strongly Austrian phenomenon and can be followed through the European, German-language, and Austrian movements of this century, up to the founding of the …

Catalytic Generation Of Hydrogen From The Hydrolysis Of Sodium-Borohydride. Application In A Hydrogen/Oxygen Fuel Cell., Clifford Mark Kaufman

LSU Historical Dissertations and Theses

Hydrogen has been promoted as the energy alternative of the future. Fuel cell utilization of hydrogen minimizes pollution while optimizing energy conversion efficiencies. Sodium borohydride has been investigated as a possible hydrogen storage and transport medium. Within the proper catalytic environment, one gram of sodium borohydride liberates almost 2.4 liters of hydrogen at a controllable rate. The effects of acids, transition metal salts, and transition metals on the hydrolysis of sodium borohydride have been mathematically quantified. Least squares analyses have reduced the data to simple combinations of algebraic expressions. Specifically, acid acceleration is subject to pseudo-first-order kinetics; equivalent acid concentrations …


Acoustic Detection Of High Energy Particles., Stanley Dean Hunter Jan 1981

Acoustic Detection Of High Energy Particles., Stanley Dean Hunter

LSU Historical Dissertations and Theses

The acoustic signals generated by charged particles traversing a medium offer a new technique for particle detection. Rapid thermal expansion of the medium produces an impulsive signal with a shape similar to one cycle of a sine wave. In the case of charged particles, the energy deposition results from thermalization of the particles ionization energy loss in the medium. A thermodynamic model which derives an acoustic potential for the signal produced by a given energy deposition is presented. The relationship between the acoustic potential and the signal period and amplitude is illustrated. Three non-thermal mechanisms (1) microbubble production; (2) molecular …


On The Biosynthesis Of Irregular Terpenes: Mechanistic Studies Employing The Thiamine Thiazole As An Isoprenoid Analogue., Steven J. Jungk Jan 1981

On The Biosynthesis Of Irregular Terpenes: Mechanistic Studies Employing The Thiamine Thiazole As An Isoprenoid Analogue., Steven J. Jungk

LSU Historical Dissertations and Theses

The irregular terpene, 2,6,9,13-tetramethyl-6-vinyl-tetradeca-2,8,12-trien-7-one (18), and the terpenoid, 1-phenyl-2,6-dimethyl-2-vinyl-hept-5-en-1-one (19) were synthesized by the Continuous Flow Reformatsky method using geranoyl chloride and benzoyl chloride, respectively. Geranyl bromide was used to generate the required organo-zinc adduct. Citral and geranyl bromide produced 3,6,9,13-tetramethyl-9-vinyl-tetradeca-3,7,12-trien-6-ol (17) by this method. Attempts to isomerize 17 to 2,6,9,13-tetramethyl-6-vinyl-tetradeca-2,8,12-trien-7-ol failed. It is postulated that 17 is more stable due to steric compression around the quaternary carbon. Comparison of 18 and the terpene isolated from yeast enzyme preparations by Bell('135) showed them to be identical. Attempts to synthesize 2-hydroxygeranyl thiamine by the addition of thiamine to citral failed. Cinnamaldehyde …

Attribution theory (Heider, 1958; Jones and Davis, 1965; Jones and Nisbett, 1972; Bem, 1967) has been modified from its usual experimental setting to serve as a theoretical model for a survey of cigarette smoking behavior. The smoking behavior of "significant others" is analyzed as an important information source in the process of belief formation. The instrument for the study was a "Health Information Questionnaire" which was given to 3014 school children (grades 3-12) in Bogalusa, Louisiana, during the 1976-1977 school year. Frequencies and percentages of students' own smoking behavior and of students by the smoking behavior of "significant others" were …


The Biology Of Beggiatoa., William Roy Strohl Jan 1980

The Biology Of Beggiatoa., William Roy Strohl

LSU Historical Dissertations and Theses

Part I. An accurate most-probable-number enumeration method was developed for counting the number of Beggiatoa trichomes from various freshwater sediments. The medium consisted of extracted hay, diluted soil extract, 0.05% sodium acetate, and 15-35 units per ml of catalase. The same enrichment medium, but without the acetate, was the best enrichment medium from which to obtain pure cultures. A total of thirty-two strains of Beggiatoa were isolated from seven different freshwater habitats and were separated into five groups based on several preliminary characteristics. Four of the groups contained cells with trichomes of approximately the same diameter (1.5-2.7 (mu)m) and may …

The Occurrence Of Alliinase In Selected Bacterial Strains., Lawrence A. Reily Jan 1980

The Occurrence Of Alliinase In Selected Bacterial Strains., Lawrence A. Reily

LSU Historical Dissertations and Theses

Alliinases have been studied in animals and plants, but relatively little attention has been given to bacterial alliinases. Therefore, an investigation was initiated to determine the prevalence and nature of alliinase systems in bacteria. A method of determining alliinase activity in bacteria was developed. The procedure was based on qualitative or quantitative detection of allicin, by a color reaction with N-ethylmaleimide. Alliinase was found to be present in some strains and absent in others. In still other strains, alliinase seemed to be a variable characteristic. It was speculated that alliin cleavage in bacteria might be accomplished via an inducible cystathionase. …
