American Civil Religion And The Presidential Rhetoric Of Jimmy Carter., Michael James Adee

LSU Historical Dissertations and Theses

Scholars have long speculated about the role of American civil religion and political discourse. Of particular interest to rhetorical scholars is the function of a civil religion idiom within presidential discourse. The cornerstone of this study is founded upon Rod Hart's ideas in The Political Pulpit (1977) wherein the nature of American civil religion is described through the metaphor of a legal contract. A rhetorical approach to civil religion provides the framework for this study. Nine major public speeches by Carter as candidate and president, from 1974 to 1979, are examined in order to locate and identify the symbolic breeches …

Non-Classical Derivation Of The Transport Theorems For Wave Fronts, R. Estrada, R. P. Kanwal

Faculty Publications

We establish a relationship between the derivatives of generalized functions and the transport theorems for moving surfaces of discontinuity. We study the motion of a propagating and deforming wave front which itself can have a moving discontinuity on its surface. With the help of the theory of generalized derivatives we present a general transport theorem which embodies the known results as special cases. © 1991.

Tide Gauge Records, Water Level Rise, And Subsidence In The Northern Gulf Of Mexico, R. Eugene Turner

Faculty Publications

Long-term water level changes in the northern Gulf of Mexico were examined using tide gauge records for this century. Strong coherence exists between the annual mean water changes at Galveston, Texas, and (1) the relatively geologically-stable west coast of Florida, (2) global mean sea level, and 93) the subsiding Louisiana coast. Water levels at the Galveston gauge, one of the longest records (81 yr), have risen steadily, but not accelerated over the long-term. The apparent acceleration of water rise in the recent two decades is within the historical pattern, and is probably driven by regional or global, but not local …

Simplified Procedure For The Isolation Of Intact Chloroplasts From Chlamydomonas Reinhardtii, Catherine B. Mason, Sharon Matthews, Terry M. Bricker, James V. Moroney

Faculty Publications

A simple procedure that yields highly purified intact chloroplasts from Chlamydomonas reinhardtii is described. This procedure involves breakage of cell wall-deficient cells by passing them through a narrow bore syringe needle. The intact chloroplasts are then purified from the crude homogenate by differential centrifugation and Percoll gradient centrifugation. This procedure generates relatively high yields of chloroplasts capable of CO2 fixation. These chloroplasts were characterized by electron microscopy, marker enzyme analysis, and ferricyanide exclusion. Transmission electron microscopy indicates that these chloroplasts retain their pyrenoids and eyespots. Scanning electron microscopy confirms that the characteristic cup shape of C. reinhardtii chloroplasts persists in …

Biological Treatment Of Hazardous Waste Sludges In Suspended Growth Systems For Removal Of Benzo(A)Pyrene And Other Polynuclear Aromatics., Robert E. Marks

LSU Historical Dissertations and Theses

The scope of this research project was to develop a bioremediation process for accelerated oxidation of bioresistant hazardous waste sludges in continuous flow sludge reactors. Benzo(a)pyrene (BaP) was selected as the target compound due its strong bioresistance, highly carcinogenic nature, extremely low aqueous solubility, and extremely low allowable release limits for land disposal. BaP is often a major hazardous organic component in many hazardous waste impoundments when source wastes have originated from either petroleum refining or associated petrochemical facilities. There is evidence that the biodegradation rate of high molecular weight polynuclear aromatic hydrocarbons (PNA's) is the rate limiting step in …

"Spades Players" And "Senators": An Ethnography Of Black Subcultures In A Community College., Anthony Louis Molina Sr

LSU Historical Dissertations and Theses

This ethnographic study of Black community college students, in a predominantly white community college, took place over a three-year period and focused on two groups. One group, the spades players, neglected their studies in favor of the card game spades, which they made the central activity of their family-like collective in the student commons. The other group, Black senators in the Student Government Association, were academic achievers who performed service to the college. By immersion into both cultures, the researcher gained the confidence of individual students in both groups, interviewed them in various settings, and looked for reasons behind the …

The Alkaloids Of Erythrina: Clonal Evaluation And Metabolic Fate., Lori Denise Payne

LSU Historical Dissertations and Theses

The foliage of thirteen genetic clones of the nitrogen-fixing trees Erythrina berteroana, E. poeppigiana and E. costarricensis growing under similar environmental conditions in the Latin American Nitrogen Fixing Tree Arboretum, CATIE, Turrialba, Costa Rica, was evaluated by gas chromatography/mass spectrometry for toxic alkaloid content. The major alkaloid identified was $\beta$-erythroidine, a naturally derived drug used in the 1950s and 1960s as a neuromuscular blocking agent in surgery and electroshock treatments. Other alkaloids identified were $\alpha$-erythroidine, erybidine, erythraline, erysodine, oxo-$\beta$-erythroidine and several previously undescribed compounds. There was a difference of more than two orders of magnitude in the $\beta$-erythroidine concentration between …

Modeling The Effect Of Shale Heterogeneities On Hazardous Waste Transport In Deep Well Disposal Systems., Seung-Whee Rhee

LSU Historical Dissertations and Theses

The transport of hazardous wastes in heterogeneous confining layers was evaluated using numerical simulations. The expected configuration of the confining layers was defined by Monte Carlo techniques assuming a binary random structure composed of pure sand and pure shale zones. Flow and solute transport in the generated configuration was determined via a finite element model. The effective permeability under saturated steady-state flow was dominated by shale permeability for higher shale fractions ($>$0.65) and by sand permeability for lower shale fraction ($<$0.4). The results agreed well with the numerical result of Desbarats (1987) and the analytical results of Dagan (1979). The effective vertical permeabilities were found to be dependent on shale size and anisotropy. Application of the techniques to a well in Jefferson Parish, Louisiana suggested that a mean advective penetration into confining layer using the injection pressure as an upper bound to the driving pressure was only 3m over 10,000 years. Transport calculations assuming a constant pressure driving force over 10,000 years suggested solute transport was controlled by hydrodynamic dispersion (dispersion + diffusion) rather than advection for higher shale fractions. Transport calculations assuming active injection for only the first 100 years suggested solute transport was controlled by diffusion for higher shale fraction. Buoyancy effects associated with salinity and temperature variations were negligible for solute transport through confining layers with a shale permeability less than 0.01 md. The results of solute transport of hazardous wastes in heterogeneous confining layers suggested that confining layers greater than 300 ft in thickness with shale fractions of greater than 0.65 and shale permeabilities of less than 0.01 md would be expected to contain injected wastes for 10,000 years.

The Clan Of Toil: Piney Woods Labor Relations In The Trans-Mississippi South, 1880-1920. (Volumes I-Iii)., John Reed Tarver

LSU Historical Dissertations and Theses

Lumber boomed in the Reconstructed South, an industrial binge that, by 1920, changed the landscape, first removing the forest then replacing its subsistence economy with consumerism. Men with money made fortunes in lumber. West of the Mississippi and south of the Missouri, it became a bonanza by 1880. Within these boundaries, black and white farmers and field hands sought "public work" in sawmills and log fronts. Most were unskilled. Steam power changed their lives, although all did not respond alike. They kept their folk ways, consistent with the new industry, despite their bondage to machines. Although most workers voluntarily entered …

Measuring Actual Evapotranspiration From Sweet Corn With Lysimeters In A Warm, Humid Climate., Faisal Kasim Ahmed

LSU Historical Dissertations and Theses

A study was conducted to determine the actual evapotranspiration of sweet corn in a warm, humid climate. Sweet corn was grown in six lysimeters at Louisiana Agricultural Experimental Station's Ben Hur Research Farm located 6 km south of Louisiana State University, Baton Rouge, Louisiana. A water balance was measured over three corn growing seasons for the following three soil moisture regimes: No irrigation or drainage (SMR1); No irrigation but drainage as needed (SMR2); and irrigation or drainage as needed (SMR3). The average actual evapotranspiration from SMR1, SMR2, and SMR3 over three seasons were 192 mm, 202 mm, and 304 mm …

Solution Adaptive Grid Procedures For High-Speed Parabolic Flows., Albert Destrehan Harvey Iii

LSU Historical Dissertations and Theses

A solution-adaptive grid procedure based on an error equi-distribution scheme is developed and applied to a Parabolized Navier-Stokes solver. The adaptation scheme re-distributes grid points line-by-line, with grid point motion controlled by forces analogous to tensional and torsional spring forces with the tensional spring force at a point proportional to the error estimate. Where the error estimates are large, the tensional forces become high and drive grid points to cluster in these high error estimate regions. Torsional terms are functions of the grid point positions along neighboring grid lines and provide grid smoothness and orthogonality. A method of selecting error …

Louisiana Principals' Perceptions Of Nontraditional Vocational Teachers And The Importance Of Vocational Education., Moo Yul Huh

LSU Historical Dissertations and Theses

Even though the elimination of sex bias and stereotyping has been a national priority in vocational education for a number of years, many educators or administrators still hold sex biased and stereotyped attitudes about labor force participation and have a belief that there are "men's" and "women's" jobs. A study of sources affecting sex bias and sex stereotyping of vocational teachers is critical to provide more productive programs. The local school principal typically has the greatest impact on school level employment decisions because the principal is the chief executive officer or administrator of the basic unit in the school system. …

New Techniques In Scene Understanding And Parallel Image Processing., Krishnakumar Narayanan

LSU Historical Dissertations and Theses

There has been tremendous research interest in the areas of computer and robotic vision. Scene understanding and parallel image processing are important paradigms in computer vision. New techniques are presented to solve some of the problems in these paradigms. Automatic interpretation of features in a natural scene is the focus of the first part of the dissertation. The proposed interpretation technique consists of a context dependent feature labeling algorithm using non linear probabilistic relaxation, and an expert system. Traditionally, the output of the labeling is analyzed, and then recognized by a high level interpreter. In this new approach, the knowledge …

The Structural Organization Of Photosystem Ii Polypeptides., William Robert Odom

LSU Historical Dissertations and Theses

The structural organization of Photosystem II polypeptides has been investigated using the protein crosslinking reagent 1-ethyl-3-(dimethyl-aminopropyl)-carbodiimide (EDC), and a library of mono- and polyclonal antibodies. The first phase of this research was to generate the antibody probes against specific PS II polypeptides. A murine monoclonal antibody, FQC3, was characterized.

Parallel And Distributed Algorithms For A Class Of Graph-Related Computational Problems., Rajanarayanan Subbiah

LSU Historical Dissertations and Theses

There exist at least two models of parallel computing, namely, shared-memory and message-passing. This research addresses problems in both these types of systems, and proposes efficient parallel (Shared-Memory Model) and distributed (message-passing) algorithms for a variety of graph related computational problems. In part I, we design algorithms for three generic problems in distributed systems: set manipulation, network structure recognition and facility placement. We present optimal distributed algorithms for recognizing rectangular-mesh networks. The time and message complexity of our algorithm is linear in the number of nodes in the network. We also lay the foundation for the recognition of 2-reducible, outer-planar …

Modern Algebra And Discrete Structures, R. F. Lax

E-Textbooks

This text is intended for either an applied algebra course or a modern algebra course that includes more applications than has been traditional. It is at an advanced undergraduate (junior-senior) level and is suitable for a one-semester or two-quarter course. We assume that students have already had a course in linear algebra (although we briefly review concepts from linear algebra when they are needed in the sections on fields and linear codes).

Our treatment is fairly rigorous, with almost every proof supplied. However, we have tried to concentrate on examples and applications. In an applied algebra course, which usually consists …

Three-Dimensional Modeling Of Reaction Injection Molding., Yu-Wen Lo

LSU Historical Dissertations and Theses

Since increasing more complex RIM molds are being used in industry, the goal of this research is to develop a model which can be used to predict the dynamic filling front, hot spots, and air entrapment in molds. In this research a method to simulate the RIM process by considering both the filling and curing stages in variously shaped molds for unsteady state three dimensional state cases was developed. This model can be used to predict not only the temperature and conversion changes with time but also the front position changing as a function time. Using given physical and chemical …

Comparative Evaluation Of Exact Extreme Value Stochastic Flood Model For Mixed Populations., Senarath T. B Ekanayake

LSU Historical Dissertations and Theses

Two alternative formulations of the exact extreme value stochastic flood model are presented in explaining the behaviour of observed flood series resulting from mixed climatological processes. As a marginal distribution for flood exceedances, a more flexible Weibull distribution is introduced in the place of the traditional exponential distribution. The asymptotic predictive performances of both the exponential and Weibull model formulations are evaluated in terms of relative bias (BIAS) and relative root mean square error (RMSE) of quantile estimation. The model with Weibull marginal performs well over the exponential for population conditions shown to exist in most of the observed flood …

An Analysis Of Syntactic Skills Used In Translating Natural Language Sentences Into Algebraic Equations., Elizabeth Devalcourt Gray

LSU Historical Dissertations and Theses

The purpose of this study is to determine how a competent person translates a natural language sentence into an algebraic equation. A current theory of how translation occurs is espoused by a group of cognitive scientists who propose that the competent translator uses only conceptual strategies in the translation process. I propose and investigate an alternate theory that the translation skills of a competent student are based on a syntactic analysis and syntactic manipulation of the sentence. In most cases such direct, syntactic translation processes will suffice, but for a small minority of sentence types a decision must be made …

Fatigue Failure Of Composite Bolted Joints., Paul Douglas Herrington

LSU Historical Dissertations and Theses

The objective of this study is to investigate the fatigue behavior of a double-lap, bolted composite joint. The material used for all tests is a quasi-isotropic graphite-epoxy laminate. Prior to fatigue testing, monotonic loading tests were performed in order to establish the important fundamental properties of friction coefficients and the ultimate bearing strength of composite joints. Proper design of friction type bolted joints for composite materials accounts for the force transmitted through friction between the clamped materials. This consideration requires knowledge of the coefficient of friction between the mating surfaces of the bolt, or washer, and the composite material. In …

Cell adhesion mediated by bonds between receptors in the cell membrane and ligands on a solid support is referred to as specific cell adhesion. This work focused on the application of specific cell adhesion in control of mixed culture fermentations and on the development of solution methods of mathematical models for cell adhesion. Through various experimental techniques, a model two-strain mixed culture system was obtained. This system was used to explore the possibility of mixed culture control through selective adhesion of particular subpopulations. It was found that through a proper reactor design and operating procedure, the coexistence of the mixed …

The Introduction Into Tobacco Plants Of Genes Which Encode Some Of The Natural Components Of The Humoral Immune Response Of Hyalophora Cecropia., Luis Julio Cesar Destefano Beltran

LSU Historical Dissertations and Theses

A number of plant pathogenic bacteria has been shown to be highly sensitive to SB-37, a derivative of cecropin B (one of the three cecropins from the giant silk moth Hyalophora cecropia). The lytic activity exhibited by SB-37 has been shown to increase up to twenty-fold in the presence of chicken egg white lysozyme. The cDNAs genes encoding SB-37, attacin E (another component of the humoral response of Hyalophora cecropia), and chicken lysozyme have been introduced into tobacco (var Xanthi) and potato (a new cultivar 86007) plants by Agrobacterium-mediated transformation using co-integrate and binary vectors. The genes were placed under …

A Neural Network Truth Maintenance System., Suresh Guddanti

LSU Historical Dissertations and Theses

A novel approach using Neural Networks has been developed to generate consistent labelling of facts in relation to a given set of rules. In the proposed system, facts are represented by neurons and their interconnections form the knowledge base. The Neural Network Truth Maintenance System(TMS) arrives at a valid solution provided the solution exists. A valid solution is a consistent labelling of facts. If a valid solution does not exist the network does not converge. An experimental setup was built and tested using conventional integrated circuits. The hardware design is suitable for VLSI implementation for large, real-time problems. The TMS …

This model, referred to as "Community Building" (CBGP), has been utilized among other ways as an intervention technique to resolve organizational/personnel problems in private, business, university, and government …

The Molecular Basis Of Imidazolinone Herbicide Resistance In Arabidopsis Thaliana Var. Columbia., Kanagasabapathi Sathasivan

LSU Historical Dissertations and Theses

Acetolactate synthase (ALS) is a key regulatory enzyme in the biosynthetic pathway of leucine, isoleucine, and valine. ALS is inhibited by four classes of structurally unrelated herbicides viz. sulfonylureas, imidazolinones, triazolopyrimidines, and pyrimidyl-oxy-benzoate. To understand the molecular basis of imidazolinone resistance, the ALS gene was isolated from an imazapyr-resistant mutant GH90 of Arabidopsis thaliana (Haughn and Somerville, 1990. Plant Physiol. 92:1081-1085). DNA sequence analysis of the mutant gene demonstrated a single point mutation from G to A at the 1958th nucleotide of the ALS coding sequence (Sathasivan et al., 1990. Nucl. Acids Res. 18:2188). This would result in serine to …
