A Matter Of Life And Death: Jose Maria Arguedas, Mario Vargas Llosa, And The Postmodern Condition., Lynn Marie Walford
A Matter Of Life And Death: Jose Maria Arguedas, Mario Vargas Llosa, And The Postmodern Condition., Lynn Marie Walford
LSU Historical Dissertations and Theses
Despite all that has been written in recent years on the subject of literary postmodernism, theorists and critics have yet to arrive at a consensus about the meaning of the term. In the context of Latin America, the theoretical disagreement is given an added dimension by an ongoing debate over whether the notion of postmodernism, in any of its manifestations, is relevant to contemporary Latin American letters. This study maintains that at least some of the issues raised in the debate over postmodernism are not only relevant, but crucial to an understanding of the many complex worlds of Latin America …
Effects Of Microstructure And Crystallographic Texture On Yield Behavior Of Aluminum-Copper-Lithium 2195 Plate., Karen Elizabeth Crosby
Effects Of Microstructure And Crystallographic Texture On Yield Behavior Of Aluminum-Copper-Lithium 2195 Plate., Karen Elizabeth Crosby
LSU Historical Dissertations and Theses
The focus of this research is to study the effects of deformation and aging on the yield behavior of precipitation-hardened Al-Cu-Li alloys, specifically AI-Cu-Li 2195 plate. Al-Cu-Li 2195 is a relatively new and exceptionally strong, yet lightweight aluminum alloy. Experimental methods applicable to mechanical/structural engineering and materials science problems provide the means for understanding the interrelation of deformation, microstructure, and crystal orientation (texture) as they affect the mechanical properties of crystalline materials. Yield strength is a vital mechanical property in that it defines the boundary of stress that may be applied to a part before a permanent, in some cases, …

Safety Of Brucella Abortus Strain Rb51 In Bull Elk, Walter E. Cook, Elizabeth S. Williams, E. Tom Thorne, Terry J. Kreeger, Glenn W. Stout, Gerhardt Schurig, Lesley A. Colby, Fred Enright, Philip H. Elzer
Faculty Publications
Some of the elk (Cervus elaphus nelsoni) of the Greater Yellowstone Area (Wyoming, Idaho, Montana; USA) are infected with Brucella abortus, the bacterium that causes bovine brucellosis. Brucella abortus strain RB51 vaccine is being considered as a means to control B. abortus induced abortions in cow elk. However, the most probable vaccination strategies for use in free-ranging elk might also result in some bull elk being inoculated, thus, it is important to insure that the vaccine is safe in these animals. In the winter of 1995, 10 free-ranging bull elk calves were captured, tested for B. abortus antibodies, and intramuscularly …

Safety And Efficacy Of Brucella Abortus Strain Rb51 Vaccine In Captive Pregnant Elk, Terry J. Kreeger, Michael W. Miller, Margaret A. Wild, Philip H. Elzer, Steven C. Olsen
Faculty Publications
Brucella abortus strain RB51 is a laboratory-derived rough mutant of virulent B. abortus strain 2308 used as a vaccine because it induces antibodies that do not react on standard brucellosis serologic tests. Strain RB51 vaccine was evaluated in pregnant captive elk (Cervus elaphus) to determine (1) if it induced abortion and (2) if it protected against abortion following subsequent challenge. The time period of this study (February-June, 1998) was similar to field conditions where elk are vaccinated and possibly exposed to B. abortus. Fourteen elk were randomly and equally divided into vaccinated and control groups. The vaccinated group was vaccinated …

Faculty Publications
We conducted three experiments to determine the influence of mechanical processing on corn silage utilization by lactating dairy cows. Total mixed rations contained either unprocessed or processed corn silage harvested between 1/4 and 3/4 milk line. In trial 1, 12 multiparous Holstein cows were used in a replicated double switchback design with 21-d periods. Intake of dry matter (DM) was increased 1.2 kg/d by processing, but milk yield was unaffected. Processing did not affect apparent total-tract DM digestibility, but processing tended to lower starch and corn excretion in feces and reduced concentration of sieved corn kernel particles in feces. In …

The tricarbocyanine dyes were synthesized to contain a heavy atom-modification to enhance k isc through spin-orbit coupling and a reactive functional group …
Effects Of Cobalt-60 Gamma Irradiation On The Malaysian Prawn Macrobrachium Rosenbergii., Nyanti Lee
Effects Of Cobalt-60 Gamma Irradiation On The Malaysian Prawn Macrobrachium Rosenbergii., Nyanti Lee
LSU Historical Dissertations and Theses
A major obstacle in culture of the Malaysian prawn, Macrobrachium rosenbergii, is the complex social structure whereby a few large males dominate the population and reduce production. The goal of this work was to induce reproductive sterility by use of gamma radiation as a means to increase production. Of the 62 publications related to the use of gamma radiation in aquatic species published between 1938 and 1996, 66% did not indicate performance of dosimetry (dosage verification). Samples were not rotated during irradiation in 98% of these studies, which introduces considerable variation in dose. A dosimetric study in this dissertation found …
Modeling Escherichia Coli Concentration In Surface Runoff: The Ecoli Model., Teck Yee Ling
Modeling Escherichia Coli Concentration In Surface Runoff: The Ecoli Model., Teck Yee Ling
LSU Historical Dissertations and Theses
A biological model, ECOLI, is developed that is capable of continuously simulating E. coli concentration in surface runoff from agricultural land applied with manure. The model was calibrated and validated by using data from field-scale studies at Franklinton, Louisiana. During validation the model was interfaced with GLEAMS-SWT model to obtain the necessary hydrologic and erosion variables as input to the ECOLI model. The ECOLI model was found to perform best when simulating runoff concentration following the first application of waste. For reapplication of waste within 50 days, the trend of decrease over time was well-simulated but simulated E. coli concentrations …

LSU Historical Dissertations and Theses
Infant low birthweight rate in East Baton Rouge Parish is higher compared to the nation. Cancer is one of the most serious health problems in Louisiana. A few studies have indicated a relationship between the two health outcomes and their environment, but conclusions from these studies have not always been consistent. The spatial and temporal scales of the data and the methods used in these studies contribute to the inconsistent and uncertain results. The spatial patterns of infant low birthweight and cancer mortality in East Baton Rouge Parish from 1993 to 1996 and their relationships with environmental factors at three …
Efficient Checkpointing For Heterogeneous Collaborative Environments: Representation, Coordination, And Automation., Kasidit Chanchio
Efficient Checkpointing For Heterogeneous Collaborative Environments: Representation, Coordination, And Automation., Kasidit Chanchio
LSU Historical Dissertations and Theses
Checkpointing can be used to adapt resource utilization in heterogeneous distributed environments. In checkpointing, the state of a process is captured and later restored on a computer to restart execution from the point where the state capturing had occurred. Such capability can be applied to process migration for which resource utilization is adapted toward high-performance by moving a running process from one computer to another. For a heterogeneous environment, problems in checkpointing can be categorized into three domains regarding mechanisms to capture and restore the execution state, memory state, and communication state of a process. Although a few solutions have …

Tetraarylboronic Acid Resorcinarenes: Synthesis, Molecular Recognition, And Templates For The Construction Of Three-Dimensional Electronic Organic Materials., Patrick Tyrone Lewis
LSU Historical Dissertations and Theses
The resorcinarenes are remarkable cyclic aromatic tetramers whose impressive impact in the disciplines of molecular recognition, materials science and supramolecular chemistry has been the subject of extensive study and recent review. The potential utility of these materials as chemosensors, catalysts, energy storage and drug delivery agents has been studied or proposed. Research involving resorcinarene molecular containers (careceplexes, carecerands, hemicarcerands) has resulted in landmark achievements including the stabilization of encapusulated cyclobutadiene and benzyne. Functionalization of the resorcinarene lower rim has begun to attract attention as a means to enhance the properties of the parent macrocycles. There has been only one report …
Efficient Iterative Synthesis Of Oligophenylene Rods And Methodology Studies Involving Aryldiazonium Tetrafluoroborate Salts And Arylboronic Esters., Douglas Macarthur Willis
Efficient Iterative Synthesis Of Oligophenylene Rods And Methodology Studies Involving Aryldiazonium Tetrafluoroborate Salts And Arylboronic Esters., Douglas Macarthur Willis
LSU Historical Dissertations and Theses
Suzuki coupling protocols were applied towards the design and subsequent iterative synthesis of oligophenylene rods bearing polar functional groups. These well-defined, polar-functionalized rigid rods were ultimately constructed using an efficient iterative molecular doubling approach without using protecting groups, boronic acid isolations, Grignard or organolithium reactions or preparative chromatographic methods. Currently, these rods are being appended to resorcinarene macrocyclic scaffolds in efforts towards achieving a controlled synthesis of novel, uniform, three-dimensional, electronic directional materials with extended, highly functional lower aromatic cavities. Unique methodology studies involving aryldiazonium tetrafluoroborate salts and arylboronic esters were also contrived and investigated. A novel procedure for the …

Well Integrity Mechanism, Failure, And Testing In Shallow Marine Sediments., Desheng Zhou
Well Integrity Mechanism, Failure, And Testing In Shallow Marine Sediments., Desheng Zhou
LSU Historical Dissertations and Theses
The leak-off test (LOT) is an in-situ method for testing casing shoe integrity in a well. It is used to evaluate the cement and formation integrity relative to the well plan specifications. The results determine whether any remedial cementing or corrective actions are required and are a basis for planning future wells in the area. Typical analysis of LOTs assumes an elastic wellbore and involves identification of linear trends on the recorded plots. However, LOTs recorded in shallow marine sediments (SMS) are inherently nonlinear and their analysis is a problem. Starting from the analyses of shallow soil properties, LOT plots, …
Agricultural Trade Liberalization And Uneven Development: The Case Of South Korea., Heesun Chung
Agricultural Trade Liberalization And Uneven Development: The Case Of South Korea., Heesun Chung
LSU Historical Dissertations and Theses
The Uruguay Round of the General Agreement on Tariffs and Trade (GATT), which was concluded in 1993, was the principal global forum to discuss agricultural trade in an extensive way. In this last venue of the GATT, South Korean negotiators had to agree to open the nation's agricultural markets so as to assure manufacturing export access to international markets amidst heightening Pressure from surplus agricultural producers A broad range of economic studies have estimated that as an aftermath of the Uruguay Round, a majority of South Korean farmers, who are comparatively disadvantaged due to small-scale, labor-intensive farming, might be displaced. …
Optimization Of Gas Well Completion And Production Practices., John H. Mcmullan
Optimization Of Gas Well Completion And Production Practices., John H. Mcmullan
LSU Historical Dissertations and Theses
In water drive gas reservoirs, wells can be completed with a long perforated interval and produced at high rates to minimize abandonment pressure and maximize recovery. Alternatively, the perforations can be limited to the top of the productive interval and the well produced at a low rate in an effort to prevent coning which results in high abandonment pressures if the strength of the aquifer is adequate to support reservoir pressure. This study uses a reservoir simulation coning model to evaluate these two conflicting completion and production practices. The impact of completion interval, gas production rate, and reservoir permeability were …

A Cultural Genealogy Of The Royal Court Theatre: The Renovation Of A Theatre And An Ideal., Stephen Douglas Berwind
LSU Historical Dissertations and Theses
The Royal Court Theatre's current renovation invites a reexamination of the English Stage Company (ESC). The ESC has entered a crucible of change, raising new questions concerning the Royal Court's architectural semiotics and company's aesthetic mission as London's most acclaimed producer of new plays. This study seeks to understand the ways in which its identity has been shaped and consolidated over the last forty-two years and how the current chapter in ESC history redefines the company's identity and future achievement. The English Stage Company took over the Royal Court in early in 1956. The ESC's marriage with the theatre appears …

Exact Relations For Effective Tensors Of Composites: Necessary Conditions And Sufficient Conditions, Yury Grabovsky, Graeme W. Milton, Daniel S. Sage
Faculty Publications
Typically the elastic and electrical properties of composite materials are strongly microstructure dependent. So it comes as a nice surprise to come across exact formulae for effective moduli that are universally valid no matter what the microstructure. Such exact formulae provide useful benchmarks for testing numerical and actual experimental data and for evaluating the merit of various approximation schemes. They can also be regarded as fundamental invariances existing in a given physical context. Classic examples include Hill's formulae for the effective bulk modulus of a two-phase mixture when the phases have equal shear moduli, Levin's formulae linking the effective thermal …

Acifluorfen Sorption, Degradation, And Mobility In A Mississippi Delta Soil, L. A. Gaston, M. A. Locke
Faculty Publications
Potential surface water and groundwater contaminants include herbicides that are applied postemergence. Although applied to the plant canopy, a portion of any application reaches the soil either directly or via subsequent foliar washoff. This study examined sorption, degradation, and mobility of the postemergence herbicide acifluorfen (5-[2-chloro-4-(trifluoromethyl)phenoxy]-2-nitrobenzoic acid) in Dundee silty clay loam (fine-silty, mixed, thermic, Aeric Ochraqualf) taken from conventional till (CT) and no-till (NT) field plots. Homogeneous surface and subsurface samples were used in the sorption and degradation studies; intact soil columns (30 cm long and 10 cm diam.) were used in the mobility study. Batch sorption isotherms were …

The treatment group visited a web site on the Dead Zone constructed for this study, and interacted with …
The Early Local And Regional Immune Response To Recall Inoculations Of Mycobacterium Leprae In The Skin Of Rhesus Macaques (Macaca Mulatta)., Thomas Xavier D Lemarchand
The Early Local And Regional Immune Response To Recall Inoculations Of Mycobacterium Leprae In The Skin Of Rhesus Macaques (Macaca Mulatta)., Thomas Xavier D Lemarchand
LSU Historical Dissertations and Theses
Epidemiological studies have failed to show any important impact of human immunodeficiency virus (HIV) infection and disease on leprosy, in contrast to the well documented increase in incidence and morbidity with other mycobacteria in these patients, notably Mycobacterium tuberculosis. The early events following exposure and repeated exposure to Mycobacterium leprae (ML) have not still been studied. Previous studies of first inoculations of ML in the skin of rhesus monkeys have indicated delayed recruitment of CD4+ cells and delayed interleukin (IL) 2 secretion in skin inoculation sites in simian immunodeficiency (SIV) positive animals. The development of the secondary immune response against …

Suburbianation: Reading Suburban Landscape In Twentieth -Century American Fiction And Film., Robert Andrew Beuka
LSU Historical Dissertations and Theses
In the years following the end of World War II, a new kind of landscape emerged in the United States, one that would immeasurably alter the way Americans think about place. Critics and commentators greeted the emergence of the environment we know as "suburbia" with a mixed reaction: for some, the suburbs represented the material embodiment of the "American Dream"; for others, architectural and environmental homogeneity marked the new suburbs as an alienating, even dangerous terrain. In the half-century since the onset of mass-suburbanization, the United States---which has, by now, become a primarily suburban nation---has continued to struggle with the …
