Palynological And Carbon-Isotopic Techniques For Reconstruction Of Paleomarsh Salinity Zones., Gail Lois Chmura Jan 1990

Palynological And Carbon-Isotopic Techniques For Reconstruction Of Paleomarsh Salinity Zones., Gail Lois Chmura

LSU Historical Dissertations and Theses

Palynological and carbon-13 analyses were studied to determine their practicality as tools for paleoecological reconstruction of marsh vegetation communities of the Mississippi delta plain. Both were calibrated on marsh surface sediment samples from four vegetation zones within Barataria Basin, Louisiana: fresh, intermediate, brackish and salt marsh. Samples were taken concurrent to vegetation sampling to allow comparison of sediment data to plant biomass and clip plot data from each of the four zones. The $\partial\sp{13}$C of sedimentary carbon reflects the proportion of C-3 and C-4 species at a site (which corresponds to a salinity gradient in the basin). The average from …

Faculty Publications

Glucose transport in skeletal muscle is mediated by two distinct transporter isoforms, designated muscle/adipose glucose transporter (Glut4) and erythrocyte/HepG2/brain glucose transporter (Glut1), which differ in both abundance and membrane distribution. The present study was designed to investigate whether differences in insulin responsiveness of red and white muscle might be due to differential expression of the glucose transporter isoforms. Glucose transport, as well as Glut1 and Glut4 protein and mRNA levels, were determined in red and white portions of the quadriceps and gastrocnemius muscles of male Sprague-Dawley rats (body wt. approx. 250 g). Maximal glucose transport (in response to 100 nM-insulin) …

Intrinsic Tryptophan Fluorescence Measurements Suggest That Polylactosaminyl Glycosylation Affects The Protein Conformation Of The Gelatin‐Binding Domain From Human Placental Fibronectin, Betty C.R. Zhu, Roger A. Laine, Mary D. Barkley

Faculty Publications

Glycosylation can affect the physical and biochemical properties of the polypeptide chain in glycoproteins. Asparagine‐N‐linked polylactosaminyl glycosylation of the chymotryptic 44‐kDa gelatin‐binding domain from human placental fibronectin confers protease resistance [Zhu, B. C. R., Fisher, S. F., Panda, H., Calaycay, J., Shively, J. E. & Laine, R. A. (1984) J. Biol. Chem. 259, 3962–3970] and weakens the binding to gelatin [Zhu, B. C. R. & Laine, R. A. (1985) J. Biol. Chem. 260, 4041–4045]. Intrinsic tryptophan fluorescence of the gelatinbinding domain was used to probe glycosylation‐dependent protein conformation changes. In gelatin‐binding fragments containing incrementally smaller polylactosamine oligosaccharides, the fluorescence intensity …

Videomicroscopic Comparison Of Bull Sperm And Leukocyte Chromosome Areas As Related To Gender, J. E. Chandler, V. Tirado, R. W. Adkinson

Faculty Publications

Chromosomal areas from metaphase spreads of male bovine leukocytes were digitized and sex chromosomes identified using videomicroscopy. Autosomal areas were ranked in descending order within a cell and assigned to two categories based on alternating rank. X and Y chromosome areas were assigned to respective categories. Areas were divided by 4 to make their sum equivalent to sperm DNA content. Data were analyzed before and after inclusion of sex chromosomal areas. Before X and Y inclusion, rank contributed to difference in chromosomal areas. Rank by category interaction and category effects did not contribute to area variation. After X and Y …

Analysis For Creep, Shrinkage And Temperature Effects On Expansion Joint Movements In Composite Prestressed Concrete Bridges., Keith Joseph Rebello Jan 1990

Analysis For Creep, Shrinkage And Temperature Effects On Expansion Joint Movements In Composite Prestressed Concrete Bridges., Keith Joseph Rebello

LSU Historical Dissertations and Theses

A rigorous and efficient analytical model to predict the long-term deformation behavior of bridges with multiple, precast, pretensioned, prestressed concrete girders supporting cast-in-place-concrete deck slabs, was developed. The analytical procedure uses the finite element method with three-dimensional 20-node isoparametric elements to realistically model bridge geometry. Time dependent effects due to load and temperature history, creep, shrinkage and aging of concrete are included in the analysis. Creep and shrinkage strains are evaluated at different times using the more commonly used procedures, namely, the ACI-209, Bazant-Panula II and CEB-FIP procedures. Temperature strains are calculated from an assumed typical bridge temperature distribution based …

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 …

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 …

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, …

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 …

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 …

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$\sb{\rm 2p}$. …

Role Duality As Represented In The Antiabolitionist Speeches Of James Shannon., Barry Cole Poyner Jan 1990

Role Duality As Represented In The Antiabolitionist Speeches Of James Shannon., Barry Cole Poyner

LSU Historical Dissertations and Theses

The dissertation alleges that a speaker may juggle roles in a given rhetorical situation, what may be termed role duality. Role duality refers to a speaker's attempt to effect multiple intentions while fulfilling or partially fulfilling multiple role expectations. A purpose of this dissertation was to speculate further on the nature and function of role duality by analyzing the speeches of James Shannon. Correspondingly, another purpose was to evaluate through rhetorical criticism the pro-slavery, anti-abolitionist speeches of Shannon. Shannon (1799-1859), an evangelist in the Churches of Christ and an influential educator, delivered two principal speeches in defense of slavery: (1) …

Existentialism And New England: The Poetry And Criticism Of Hayden Carruth., Anthony Jerome Robbins Jan 1990

Existentialism And New England: The Poetry And Criticism Of Hayden Carruth., Anthony Jerome Robbins

LSU Historical Dissertations and Theses

Hayden Carruth (b. 1921) has reached an advanced stage in his distinguished career as a poet, critic, and editor without having received the critical attention which he deserves and which has been accorded many of his less able contemporaries. He is a thorough-going existentialist, a dyed-in-the-wool Yankee, and an anarchist. The study uses these characteristics to explore the importance of his poetry and the nature of his complex relations with his chosen traditions. The first three chapters describe and analyze Carruth's development book by book from 1959 to 1983. The fourth chapter, "Carruth's Existential Revisions of Walden," considers Carruth's response …

Individual Motives For Campaign Giving., Sheldon D. Beychok Jan 1990

Individual Motives For Campaign Giving., Sheldon D. Beychok

LSU Historical Dissertations and Theses

The basic assumptions of this study are that individual contributors to campaigns are motivated by a desire to enhance their self-esteem through access, acquired through giving, and that large givers exhibit behavior that indicates a greater desire for access. Large givers exhibit such behavior to a significantly greater extent than moderate or small givers, and seek "status" by giving for other than politically-explicit reasons. It is hypothesized that: (I) All contributors have a greater sense of political efficacy and greater trust in government than the general public. (II) Individuals contribute as a result of conventional, acceptable motives, which are: (1) …

Isolation And Physical Mapping Of The Mitochondrial Chromosome From The Zygomycete Mucor Racemosus., Mary Louise Schramke Jan 1990

Isolation And Physical Mapping Of The Mitochondrial Chromosome From The Zygomycete Mucor Racemosus., Mary Louise Schramke

LSU Historical Dissertations and Theses

Mitochondria were isolated from Mucor racemosus and DNA was purified from these organelles by cesium chloride/ethidium bromide isopycnic centrifugation. Examination of mitochondrial DNA samples with a transmission electron microscope revealed a circular mitochondrial chromosome approximately 63.8 kbp in length. Summation of restriction fragments of mitochondrial DNA separated by agarose gel electrophoresis yielded a comparable value of 63.4 kbp for the size of the intact molecule. Electrophoretic mobility and stoichiometry were determined for restriction fragments generated using nine different restriction enzymes. A physical map was deduced from single and double digestions of mitochondrial DNA with several of the restriction enzymes. The …

A New Approach To Analyzing High-Resolution Aerial Photographs Of Urban Areas., Timothy Dwayne Phillips Jan 1990

A New Approach To Analyzing High-Resolution Aerial Photographs Of Urban Areas., Timothy Dwayne Phillips

LSU Historical Dissertations and Theses

This dissertation proposes a new approach for analyzing high resolution aerial photographs of urban areas. Analyzing aerial photographs is the process of constructing an overall description of a scene. It involves knowledge of visual sensors, computing systems, artificial intelligence, software engineering, and perceptual psychology. Researchers have had only limited success in this area. This dissertation considers a high level analysis approach. Most aerial photograph interpretation systems concentrate on analyzing an airport, roadway, or urban scene. Those systems, however, do not explain how they know they were examining such a scene. This dissertation concentrates on how to reach that point. It …

Coronary Heart Disease, Negative Affectivity, And Response Bias., Sharon Elaine Alcock Parisi Jan 1990

Coronary Heart Disease, Negative Affectivity, And Response Bias., Sharon Elaine Alcock Parisi

LSU Historical Dissertations and Theses

The purpose of this study was to examine the relation between negative affectivity, a broad band construct of negative emotions, and coronary heart disease. It was hypothesized the relation had been obscured in previous research by the tendency of some subjects to underreport negative affects. To test this hypothesis, 78 male cardiac patients between to ages of 37 and 65, who had undergone cardiac arteriography procedures within the previous 6 months, were given the Taylor Manifest Anxiety Scale Short Form (TMAS-S; Bendig, 1956) and the Marlowe-Crowne Social Desirability Scale Form C (MCSD-C; Reynolds, 1982).

The Narrative Creation Of Self In The Fiction By African-American And African-Caribbean Women Writers., Jerome P. De Romanet Jan 1990

The Narrative Creation Of Self In The Fiction By African-American And African-Caribbean Women Writers., Jerome P. De Romanet

LSU Historical Dissertations and Theses

This study entails an examination of the works of six authors (Maya Angelou, Audre Lorde, Paule Marshall, Toni Morrison, Gloria Naylor and Simone Schwarz-Bart) whose works are shaped by values and perceptions influenced by their experiences of sexual, racial and social marginalization. While I acknowledge differences in origin, beliefs and personality, I explore the common ground which unites them, and more specifically the complex ties that bind their individual "writing I" with their environment--"communitas," to use Victor Turner's term. This study is also an exploration of the modes in which these six writers create their idiosyncratic selves out of the …

The Eating Disorders Diagnostic Inventory (Eddi): The Development Of A New Assessment Instrument., Cecilia Jo Davis Jan 1990

The Eating Disorders Diagnostic Inventory (Eddi): The Development Of A New Assessment Instrument., Cecilia Jo Davis

LSU Historical Dissertations and Theses

The area of eating disorders have been intensively by both the psychological and medical researchers over the last two decades. Differential diagnosis of the four most prevalent eating disorders (anorexia nervosa, bulimia nervosa, compulsive overeating, and the non-binging obese) continues to be a problem for both researchers and clinicians. Diagnosis of these disorders has been complicated by the many changes in diagnostic criteria for each of the disorders. One consequence of these frequent changes is that there is no single self-report inventory for differential diagnosis which is based on currently accepted diagnostic criteria. The purpose of this study was the …

Design Of A Two-Stage Procedure For Three-Class Screening., Chungtae Kim

LSU Historical Dissertations and Theses

A two-stage screening procedure is developed for a situation where the items can be sold in one of two markets, or scrapped. The item's selling price and product specifications differ for each market. In the first stage of the screening procedure, each item is inspected on a surrogate variable that is correlated with the performance variable of interest. If a decision is not reached at this point, the item is subjected to a second-stage inspection on a performance variable. A loss in selling price is incurred by the producer when an item that meets the specifications of a higher-price market …
