Evaluation Of Selected Pulmonary Function Tests In Resting Thoroughbred Horses Having Reversible, Experimentally Induced Respiratory Dysfunctions., Alan John Guthrie Jan 1990

Evaluation Of Selected Pulmonary Function Tests In Resting Thoroughbred Horses Having Reversible, Experimentally Induced Respiratory Dysfunctions., Alan John Guthrie

LSU Historical Dissertations and Theses

The purpose of the first part of this study was to develop computerized techniques for automation of instrument calibration, data collection and calculation of indices of pulmonary mechanical function in resting and exercising horses. The microcomputer system developed enabled a single trained technician to reliably operate the equipment in an equine pulmonary mechanics laboratory. The first experiment investigated the temporal effects of histamine and methacholine aerosols on indices of pulmonary mechanics derived from the linear equation of motion. Data calculated on a breath-by-breath basis were too variable to be reliably modeled. Following application of averaging techniques, the temporal effects of …

Beta-Endorphin Receptors On Equine Lymphocytes: Relationship To Immune Function And Exercise., Jena Gosselink Hamra Jan 1990

Beta-Endorphin Receptors On Equine Lymphocytes: Relationship To Immune Function And Exercise., Jena Gosselink Hamra

LSU Historical Dissertations and Theses

Current evidence suggests that endogenous opioids are released in response to various stressors and that these opioids interact with cells of the immune system, and modulate immune function. However, data substantiating this are conflicting. Therefore, this study endeavored to clarify the role of beta-endorphin (BE) in exercise and immune function. Beta-endorphin exhibited a diurnal rhythm in the horse with peak plasma levels occurring at 0900 hours. Analgesia, tachycardia and mydriasis were also observed at this time, mimicking the effects of morphine in the horse. Therefore, subsequent experiments were performed at 0900 hours during times of increased basal opioid activity. Beta-endorphin …

Assessment Of Athletic Potential And Augmentation Of Performance In Thoroughbred Racehorses., John Daniel Harkins Jan 1990

Assessment Of Athletic Potential And Augmentation Of Performance In Thoroughbred Racehorses., John Daniel Harkins

LSU Historical Dissertations and Theses

The purposes of this dissertation were to (1) determine running abilities of horses on the racetrack, (2) design treadmill standard exercise tests (SETs) to measure exercise variables that correlate with racetrack performance, and (3) assess the influence of training, competition, and ergogenic aids on performance. Run times of 25 Thoroughbreds were determined during solo and competitive track runs of 1200, 1600, and 2000 meters. Cardiac, respiratory, and hematologic variables were later measured during treadmill SETs. Variables were correlated with average run times. Heart rate scores, V$\sb{200}$, plasma lactate values, and maximal oxygen uptake correlated best with performance. Interval and conventional …

Effects Of Gel Teat Cleaning And Sanitizing On Raw Milk Quality And Udder Health., Kasimu Hudu Ingawa

LSU Historical Dissertations and Theses

Thirty lactating Holstein cows were divided into three groups of ten each and assigned to three treatments. The first treatment required using a gel teat sanitizer cleaner (GEL) and paper towels, no water to clean teats prior to milking. The second used only water (WASH) and paper towels, and the third used water, paper towels, and predipping (PREDIP) with 0.5% iodophor solution. Individual cow samples of milk were aseptically collected weekly from weigh jars for ten weeks. Bacteria counts were determined. Microorganism counts were also monitored from individual cow teat swabs. Treatment effects on daily milk yield, fat and protein …

An Adaptive Control System For Biological And Robotic Simulations., Sunggyu Kwon

LSU Historical Dissertations and Theses

An adaptive control algorithm based on Albus' CMAC (Cerebellar Model Articulation Controller) was studied with emphasis on how to build a Multilayered CMAC Control System. This concept has been devised to circumvent the excessive memory requirements of CMAC controllers for complex control systems with many inputs. The Neighborhood Sequential Training technique was devised as a general CMAC training technique. This training technique is straightforward to implement and well matched to CMAC's memory generalization. A two-layered CMAC control module was simulated for a six dimensional CMAC problem of trajectory control for a six degree of freedom manipulator. Layering was accomplished by …

In Situ And Laboratory Evaluation Of Liquefaction Resistance Of A Fine Sand., Behnam Mahmoodzadegan Jan 1990

In Situ And Laboratory Evaluation Of Liquefaction Resistance Of A Fine Sand., Behnam Mahmoodzadegan

LSU Historical Dissertations and Theses

Liquefaction is a phenomenon during which saturated cohesionless soils lose a major portion of their shear strength, and can potentially cause catastrophic failures. This study was focused on the in-situ and laboratory evaluation of liquefaction risk. Several types of penetration tests were performed. Four procedures were selected to evaluate the liquefaction potential of a number of sandy sublayers in two sites with well-documented seismic history. A new hollow cylinder equipment, which allows performing monotonic or cyclic liquefaction tests on annular soil specimens, was designed, fabricated and calibrated. The laboratory testing program included monotonic and cyclic liquefaction tests using two different …

Working-Class Culture: Definition And Outcomes., Joan Marie Morris Jan 1990

Working-Class Culture: Definition And Outcomes., Joan Marie Morris

LSU Historical Dissertations and Theses

This dissertation is a quantitative analysis of the dynamics of class culture. The project has two primary components. In part one I construct a class categorization scheme in which occupations are grouped according to the substantive complexity of work. In part two, I conduct four separate sub-analyses, each of which uses a pre-existing dataset to model the effects of class status on four dimensions of class culture: orientations to work, family power, political orientation, and class self-identification. In regard to work, I find that task complexity has an independent effect on job satisfaction; that manual workers, more than nonmanual workers, …

Stress And Headache., Thomas Hamilton Mosley Jr Jan 1990

Stress And Headache., Thomas Hamilton Mosley Jr

LSU Historical Dissertations and Theses

Stress is the most frequently cited precipitant of both migraine and muscle-contraction headache. Although stress is thought to play a causal role in the etiology of headache, past research has relied solely on cross-sectional designs and between-subjects data analytic techniques, thus severely restricting conclusions regarding causality and obscuring potentially meaningful individual variability. The present investigation provided a partial replication and extension of prior research on the relation between minor stress and headache and attempted to redress a number of prior methodological shortcomings. A longitudinal design and within subject, lagged, time-series regression analyses were employed. Migraine (n = 26) and muscle-contraction …

The Relations Between Stress, Mood And Insomnia., Susan Rubman Jan 1990

The Relations Between Stress, Mood And Insomnia., Susan Rubman

LSU Historical Dissertations and Theses

Stress is hypothesized to cause increased cognitive and physiological arousal which is incompatible with sleep. Major life events have been implicated as a significant factor in the onset of chronic insomnia (Healey et al., 1981), and there is some suggestion that minor life events influence symptoms as well (Haynes et al., 1981). The present study was designed to evaluate and further clarify the role of daily minor stressors and mood variables on sleep in both normal sleepers and insomniacs. Subjects with insomnia secondary to medical or physical disorders were excluded from this study. Fifty-four adult subjects (20 mixed-complaint insomniacs, 17 …

A Rock-Plant Filter Bench-Scale Study And Computer Model., Donna Gail Skipper

LSU Historical Dissertations and Theses

In Part One, three bench-scale rock filters containing 2 feet of gravel were investigated. Two of the filters were planted with Sagittaria lancifolia and Scirpus validus, while the third filter was an unvegetated control filter. During a preliminary portion of this study, the BOD$\sb5$ surface loading was held constant at 4.96 g/day/m$\sp2$. The BOD$\sb5$ mass removal percentages at this time averaged 75%, 60%, and 44% for the Scirpus, Sagittaria, and control systems, respectively. Following this constant loading rate, an 80-day experiment was run on the filters using eight combinations of two flow rates and four influent BOD$\sb5$ concentrations, each combination …

With The Flavor Of The South: The Influence Of The Southern Tradition On The Writings Of Shirley Ann Grau., Judy Ann Tarver Jan 1990

With The Flavor Of The South: The Influence Of The Southern Tradition On The Writings Of Shirley Ann Grau., Judy Ann Tarver

LSU Historical Dissertations and Theses

Since before the time of the so-called Southern Renaissance of the 1920's, critics have been debating the existence and the value of a literature of the South. Although they agree on little else, most would concur that such a literature would share certain characteristics: a belief in the importance of community and the past; a tendency to prefer myth, or a perception of reality, to reality itself; a religious sensibility, especially a pervading sense of sin and guilt; an emphasis on place; and the use of elements of the Gothic. For thirty-five years Shirley Ann Grau has been writing fiction …

Effects Of Artificial Mineral Licks On White-Tailed Deer., Stephen Redmore Schultz Jan 1990

Effects Of Artificial Mineral Licks On White-Tailed Deer., Stephen Redmore Schultz

LSU Historical Dissertations and Theses

A commercial mineral mixture for deer was used to evaluate the effects of broad-spectrum dietary mineral supplementation on white-tailed deer (Odocoileus virginianus) growth, antler development, and tissue mineral content. Forty-two artificial mineral licks for deer were established on 3 study areas in East Feliciana Parish, Louisiana. All licks were monitored monthly, recharged to original level if used, and mineral consumption recorded from May 1988 through December 1989. Consumption data were converted to estimated average per deer values based on population estimates. Effects of artificial lick mineral consumption on free-ranging deer were examined by comparing deer harvested during the 1988-89 and …

Predicting Pseudoneglect By Right Hemisphere Activation., Mark Sterling Warner Jan 1990

Predicting Pseudoneglect By Right Hemisphere Activation., Mark Sterling Warner

LSU Historical Dissertations and Theses

Hemispatial neglect is a visual-perceptual disorder characterized by a conscious and otherwise alert individual's failure to respond to a meaningful stimulus presented to the side opposite a right hemisphere brain lesion. In recent years researchers have demonstrated the existence of a neglect phenomenon in normal subjects which appears as the opposite of that experienced by brain injured subjects. This phenomenon is referred to as "pseudoneglect" and is demonstrated by horizontal line bisection to the left of true center. Researchers have suggested that pseudoneglect may be explained by preferential right hemisphere processing for visuospatial stimulation. The purpose of this study was …

The Combustion Of Linear Droplet Arrays In A Coaxial Convective Flow., Jeng-Syan Tsai Jan 1990

The Combustion Of Linear Droplet Arrays In A Coaxial Convective Flow., Jeng-Syan Tsai

LSU Historical Dissertations and Theses

As approximations for spray-combustion processes, a series of increasingly sophisticated numerical models has been developed to simulate the combustion of linear droplet arrays in a co-axial, convective flow. Common to all of the models is an embedded grid, developed to increase computational accuracy. The first and simplest model is potential flow model (for Re $\to$ $\infty$). The flow is assumed to be ideal and infinitely-fast kinetics (flame sheet assumption) represent the combustion. The results show that the instantaneous droplet burning rates are increased as the droplet spacing is increased, and the burning rates of droplets tend asymptotically to smaller values …

Rice Improvement Through Tissue Culture: Inheritance Of Somaclonal Variation And Improvement Of Somaculture Techniques., Qingjun Xie Jan 1990

Rice Improvement Through Tissue Culture: Inheritance Of Somaclonal Variation And Improvement Of Somaculture Techniques., Qingjun Xie

LSU Historical Dissertations and Theses

The objectives of this research were to study the inheritance of homozygous variation from rice somaculture, to select rice somaclones for increased sheath blight resistance, and to determine the mode of inheritance of the resistance. To accomplish these objectives it was necessary to improve somaculture techniques for rice suspension and protoplast culture especially for the American long-grain cultivars. A method for incorporation of the chemical mutagen, ethyl methane-sulfonate (EMS), into the somaculture system was also developed to increase the frequency of somaclonal variation in tissue culture stable cultivars. The inheritance of six homozygous variant characteristics from five somaclones was investigated. …

Claude Simon Et L'Espace Optique. [French Text]., Jean-Luc Briastre Jan 1990

Claude Simon Et L'Espace Optique. [French Text]., Jean-Luc Briastre

LSU Historical Dissertations and Theses

This study entails of an analysis of the visual space in certain novels of Claude Simon: La Route des Flandres, La Bataille de Pharsale, Orion aveugle, Les Corps conducteurs, Triptyque, Lecon de choses. The fragmentation of Simon's narrative makes the reader rely on the novels' imagery to establish a cohesiveness. Simon describes the formation of the image as a process akin to photographic development. For Simon, the image is, primarily, the physical impression of light particles. This first step leads to a comparison between the impressions of the form projected onto a screen (which is similar to a retina) and …

Probabilistic Analysis Of Bridge Scour Using The Principle Of Maximum Entropy., Donald Edward Barbe' Jan 1990

Probabilistic Analysis Of Bridge Scour Using The Principle Of Maximum Entropy., Donald Edward Barbe'

LSU Historical Dissertations and Theses

The probability distribution function for floods and velocity profile in open channel flow are combined with scour theory to present a procedure for determining the risk of bridge failure due to scour. This is accomplished by deriving a probability distribution function for scour at a bridge pier. The theory of entropy and the principle of maximum entropy are used to determine the velocity profile. The constraints used in the entropy maximization are derived from the physical laws of conservation of mass, momentum, and energy. A procedure to approximate the solution to the resulting equations is shown. The vertical velocity is …

The Results Of The Edict Of Toleration In The Southern Austrian Province Of Carinthia During The Reign Of Joseph Ii., Barry Royce Barlow Jan 1990

The Results Of The Edict Of Toleration In The Southern Austrian Province Of Carinthia During The Reign Of Joseph Ii., Barry Royce Barlow

LSU Historical Dissertations and Theses

Historians have debated whether the radical reforms of the Habsburg Emperor Joseph II (1780-1790) were motivated by the spirit of Enlightenment or simply by Realpolitik. The purpose of this work is to go beyond the legal and philosophical discussion surrounding this debate; to examine the effects of one piece of legislation, the Edict of Toleration, as the government interpreted and applied it in the southern province of Carinthia; and in so doing, to provide a clearer picture of the person of the Emperor and his bureaucracy. While today's conception of toleration includes an equal recognition and respect for all rights, …

Panel Analysis: A Critical Method For Analyzing The Rhetoric Of Comic Book Form., Ralph Randolph Duncan Ii Jan 1990

Panel Analysis: A Critical Method For Analyzing The Rhetoric Of Comic Book Form., Ralph Randolph Duncan Ii

LSU Historical Dissertations and Theses

This study devises a method of rhetorical criticism, panel analysis, for the comic book medium. Panel analysis focuses on how the unique form of the comic book medium communicates content. Panel analysis consists of three components: historical context, micro analysis, and macro analysis. The historical component makes use of a humanistic historical approach to place a comic book or a body of comic book work in the contexts of the creator's personal history and the evolution of the comic book medium. These contexts provide understanding of the origins of the various formal aspects of the work(s) being studied. The micro …

A Monte Carlo Comparison Of Tests For Multivariate Normality Based On Multivariate Skewness And Kurtosis., Ronald Larry Horswell Jan 1990

A Monte Carlo Comparison Of Tests For Multivariate Normality Based On Multivariate Skewness And Kurtosis., Ronald Larry Horswell

LSU Historical Dissertations and Theses

The assumption of multivariate normality (MVN) underlies many common parametric multivariate statistical procedures, and numerous tests have been defined for testing the assumption. Among these tests, those based on concepts of "multivariate skewness" and "multivariate kurtosis" hold special interest since they appear to test for specific types of departures from MVN. This research uses Monte Carlo simulation to compare the performance of several MVN tests which are based on various definitions of multivariate skewness and kurtosis. Specifically, the tests are Mardia's (1970) b$\sb{\rm 1,p}$ and b$\sb{\rm 2,p}$, Small's (1980) Q$\sb1$ and Q$\sb2$, and Srivastava's (1984) b$\sb{\rm 1p}$ and b$\sb{\rm 2p}$. …

Attribution Processes In Mother-Adolescent Conflict., Nancy Caryn Grace Jan 1990

Attribution Processes In Mother-Adolescent Conflict., Nancy Caryn Grace

LSU Historical Dissertations and Theses

Because of the potentially serious consequences associated with parent-adolescent conflict, researchers have delineated variables (i.e., communication skills deficits) that might escalate conflict. Despite the theoretical support for the role of cognitive variables in parent-adolescent conflict, this area has received little research attention. In contrast, studies using adult subjects have repeatedly demonstrated a relationship between cognitive variables, (i.e., attributions) and conflict behaviors and relationship dissatisfaction. Researchers have found that distressed spouses tend to emphasize aversive spousal behaviors by attributing them to global and stable causes that reside within their spouses. Additionally, they perceive negative behavior as intentional, selfishly motivated, and blameworthy. …

Genotypic And Phenotypic Adaptations Of The Southern Oyster Drills, Stramonita Canaliculata And S. Haemastoma Floridana To Salinity., Li-Lian Liu Jan 1990

Genotypic And Phenotypic Adaptations Of The Southern Oyster Drills, Stramonita Canaliculata And S. Haemastoma Floridana To Salinity., Li-Lian Liu

LSU Historical Dissertations and Theses

Environmental and genetic effects on salinity adaptation in the southern oyster drill were estimated by their salinity-related genotypic (i.e. determined by electrophoresis) and phenotypic (i.e. determined by salinity tolerance and microcalorimetry) variations. The systematics of Stramonita haemastoma were studied using allozyme, radular and shell characteristics to exclude taxonomic differences which might have obscured variations in salinity adaptation. Radular and shell features are not reliable as systematic characteristics. S. h. canaliculata and S. h. floridana are separable using allozyme characteristics. Nei's genetic distance (D = 0.28) and the fixed allelic differences in Fum, LeuAla, Mdh, and 6-Pgdh indicate that the differences …
