Predictions For Multi-Scale Shock Heating Of A Granular Energetic Material, Venugopal Jogi Jan 2003

Predictions For Multi-Scale Shock Heating Of A Granular Energetic Material, Venugopal Jogi

LSU Master's Theses

This thesis addresses the multi scale heating of a granular energetic solid due to shock loading. To this end, an existing mathematical model that has been used to predict low pressure bulk and localized heating of the granular high-explosive HMX ([CH2NNO2]4) is extended to account for compressibility and melting of the pure phase solid. Dense granular HMX has a heterogeneous structure composed of randomly packed small grains (average size ~ 100 µm) having a free-pour density that is approximately 65% of the pure phase solid density. The shock loading response of this material is …

Random Centroid Optimization Of Lutein-Enriched Oil In Water Emulsion At Acidic Ph, Armen Khachatryan Jan 2003

Random Centroid Optimization Of Lutein-Enriched Oil In Water Emulsion At Acidic Ph, Armen Khachatryan

LSU Master's Theses

Age-related macular degeneration (AMD) is a physiological condition that affects the elderly, diabetic patients, and leads to loss of vision. There are no effective therapies for AMD. The role of nutrition in preventing AMD is receiving strong scientific scrutiny. Lutein and zeaxanthin have been identified as dietary strategies that can delay the onset of AMD. Consumption of at least six milligrams of lutein per day has been reported to delay the onset of AMD by as much as 43%. However, most available food sources contain such low levels of lutein that it would be difficult to meet the daily requirement. …

Remembrances Of Things Past And Future: Memory And Its Significance For Politics In Nietzsche, Sophocles, And Isaiah, Michael Henderson Jan 2003

Remembrances Of Things Past And Future: Memory And Its Significance For Politics In Nietzsche, Sophocles, And Isaiah, Michael Henderson

LSU Master's Theses

This thesis is an inquiry into memory and its significance for politics as described in three sources. Part of its task is to grasp Nietzsche’s phenomenology of memory thought and to inquire into what understanding about politics emerges. Nietszche speaks about memory with respect to the self, yet he offers little elaboration about intersubjectivity or transcendence for linking memory to justice. To further investigate his approach, this essay examines two other texts, Philoctetes, by Sophocles, and Isaiah, which set this discussion on a political stage. What emerges is an approach to how memory can have an impact on self, community, …

Out The Loop, Matthew Christian Anderson Jan 2003

Out The Loop, Matthew Christian Anderson

LSU Master's Theses

Often referred to as resembling an architectural blueprint, the screenplay is known for its laconic style. Discarding the subjective abstractionism of a more flowery writing, the screenplay's brevity forces the writer to make use of the physical world of the text to display its underlying currents of thought. This trend in artistic representation, of which the influence has been heatedly discussed since the onset of the cinema, is not stagnant but evolving. The screenwriters of today produce their craft with an increased savoir faire not only in relation to plot and form but also in regards to the aesthetics of …

Role Of Eintermediaries In The United States Paper Supply Chain, Sanna Maria Kallioranta Jan 2003

Role Of Eintermediaries In The United States Paper Supply Chain, Sanna Maria Kallioranta

LSU Master's Theses

In an attempt to streamline the paper supply chain, paper industry vertical business-to-business eMarketplaces were established to help industry players to decrease inefficiencies in their supply chains, to minimize negative effects of economic cyclicality, and to achieve better visibility. eMarketplaces rode the hype of revolutionizing the way in which industries conduct business, citing the cost savings achieved by expanded market reach, operational efficiencies, aggregated purchasing, and finding the least expensive suppliers. Adoption of eIntermediaries has been lower than expected in the paper industry and many of the paper vertical start-ups failed when the economy softened and the dot.com bubble burst. …

U.S. Regional Newspapers' Coverage On China's Entry Into The Wto--A Regional Economy Approach, Ying Kong Jan 2003

U.S. Regional Newspapers' Coverage On China's Entry Into The Wto--A Regional Economy Approach, Ying Kong

LSU Master's Theses

The purpose of this study is to examine whether a region's economy has an impact on regional coverage of China's WTO entry. It is predicted that regional newspapers vary in reporting this issue because of variation in the regional economic structure. The findings of the study support this prediction. A content analysis of 282 news articles in the U.S. regional newspapers finds that the regional economy can be a predictor of regional newspaper's coverage. For North Carolina, Illinois and California, significant differences exist in the regional coverage of China's WTO accession in terms of reference to key economic issue, reference …

Equations Of Parametric Surfaces With Base Points Via Syzygies, Haohao Wang Jan 2003

Equations Of Parametric Surfaces With Base Points Via Syzygies, Haohao Wang

LSU Doctoral Dissertations

Suppose $S$ is a parametrized surface in complex projective 3-space $mathbf{P}^3$ given as the image of $phi: mathbf{P}^1 imes mathbf{P}^1 o mathbf{P}^3$. The implicitization problem is to compute an implicit equation $F=0$ of $S$ using the parametrization $phi$. An algorithm using syzygies exists for computing $F$ if $phi$ has no base points, i.e. $phi$ is everywhere defined. This work is an extension of this algorithm to the case of a surface with multiple base points of total multiplicity k. We accomplish this in three chapters. In Chapter 2, we develop the concept and properties of Castelnuovo-Mumford regularity in biprojective spaces. …

Adherence To Medical Regimens In Low-Income Adults With Type 2 Diabetes: The Influence Of Perceived Control Constructs, Erin L. O'Hea Jan 2003

Adherence To Medical Regimens In Low-Income Adults With Type 2 Diabetes: The Influence Of Perceived Control Constructs, Erin L. O'Hea

LSU Doctoral Dissertations

Individuals with Type 2 diabetes often do not adhere to their treatment regimens (e.g., exercise, diet, medication, glucose monitoring). Non-adherence results in poor metabolic control, further morbidity and mortality, and increased health care utilization and costs. One common thread among many health-behavior-theories that attempt to explain non-adherence behaviors is the importance of perceived control. This psychosocial variable has most often been conceptualized as ‘health locus of control,’ which refers to the belief that one has the ability to influence or change one’s health outcomes. Inconsistent findings have been reported regarding the relationship of health locus of control and medical regimen …

Application Of Mechanistic Models In Predicting Flow Behavior In Deviated Wells Under Ubd Conditions, Faisal Abdullah Aladwani Jan 2003

Application Of Mechanistic Models In Predicting Flow Behavior In Deviated Wells Under Ubd Conditions, Faisal Abdullah Aladwani

LSU Master's Theses

Underbalanced drilling (UBD) has increased in recent years because of the many advantages associated with it. These include increase in the rate of penetration and reduction of lost circulation and formation damage. Drilling of deviated and horizontal wells also increased since recovery can be improved from a horizontal or a deviated well. The drilling of deviated wells using UBD method will reduce several drilling related problems such as hole cleaning and formation damage. Prediction of flow and pressure profiles while drilling underbalanced in such wells will help in designing and planning of the well. The main aim of this research …

Iddq Testing Of A Cmos 10-Bit Charge Scaling Digital-To-Analog Converter, Srinivas Rao Aluri

LSU Master's Theses

This work presents an effective built-in current sensor (BICS), which has a very small impact on the performance of the circuit under test (CUT). The proposed BICS works in two-modes the normal mode and the test mode. In the normal mode the BICS is isolated from the CUT due to which there is no performance degradation of the CUT. In the testing mode, our BICS detects the abnormal current caused by permanent manufacturing defects. Further more our BICS can also distinguish the type of defect induced (Gate-source short, source-drain short and drain-gate short). Our BICS requires neither an external voltage …

The Means Of Ignorance: Genuine Dialogue And A Rhetoric Of Virtue, Daniel Anthony Grano Jan 2003

The Means Of Ignorance: Genuine Dialogue And A Rhetoric Of Virtue, Daniel Anthony Grano

LSU Doctoral Dissertations

Aimed at core problems of contemporary moral rhetoric - pluralistic argument, incommensurable disagreement on ordering terms, and a theoretical move away from essence to relativism - this study is an attempt to restore rhetoric as an art capable of investigating and positing terms of order and being. This restoration relies upon viewing rhetoric as a practice of epistemic mediation between the experiential and language-based knowledge of the local, and the perfected knowledge of the Absolute. I propose characteristically Socratic notions of contingency and ignorance as the bases for this mediated approach. As a recognition of what is unknown and uncertain …

Role Of Endothelin In The Pathogenesis Of Acute Laminitis In Horses, Ashley Michelle Stokes Jan 2003

Role Of Endothelin In The Pathogenesis Of Acute Laminitis In Horses, Ashley Michelle Stokes

LSU Doctoral Dissertations

Acute laminitis is a severely debilitating disease of the laminae of the equine digit; however, the mechanism(s) of pathogenesis have yet to be fully elucidated. In physiologic states, the endothelium synthesizes substances, such as nitric oxide (NO; vasodilator) and endothelin-1 (ET-1; profound vasoconstrictor), which play a crucial role in vasomotor regulation. The overall hypothesis is that the initiating factor in the onset of acute laminitis is a disruption in the balance between NO and ET-1, which leads to digital vasoconstriction and subsequent laminar ischemic necrosis. In vitro studies with digital vessels from healthy horses and horses with naturally-acquired laminitis determined …

Angle-Resolved Photoemission Study And Neutron Diffraction Measurements On Lasb2, Alice Acatrinei Jan 2003

Angle-Resolved Photoemission Study And Neutron Diffraction Measurements On Lasb2, Alice Acatrinei

LSU Doctoral Dissertations

LaSb2 has recently been found to have unusual magnetoresistive properties despite the fact that neither La nor Sb are magnetic. The resistance is anisotropic, and at high magnetic fields presents an anomaly that might be a result of a charge density transition. The magnetoresistance is anisotropic and linear, and the resistivity presents high relative changes when a magnetic field is applied. Discovered in 1954, LaSb2, as the rest of the light rare-earth diantimonides, was poorly studied. The anisotropic magnetic properties reported in 1998 by Bud'ko, Canfield and their collaborators make the series very interesting. A description of …

Assia Djebar. Le Corps Invisible: Voir Sans Etre Vue, Anna Rocca

LSU Doctoral Dissertations

This thesis traces the evolution of attitudes towards the body, desire, autobiography, and self-affirmation, in three novels of Assia Djebar: L'amour, la fantasia, Vaste est la prison, and Les nuits de Strasbourg. The three novels share a common trait: the narrators' will to express their body and their desires. This body, which is simultaneously anonymous and concealed, is at the very center of a contradiction; it is often relegated to representation as a ghost without any corporeal reality. It is been our objective to follow the narrators' introspective reflection on the multiple relationships between Algerian women and public space, designated …

Equine Immunity To Cyathostome Infections, Marie Alexandra Baudena Jan 2003

Equine Immunity To Cyathostome Infections, Marie Alexandra Baudena

LSU Doctoral Dissertations

To study the protective responses of cyathostome-infected ponies, two challenges were performed employing animals with different histories of exposure to these parasites. The hypothesis developed and to be tested in these experiments was that ponies that had longer exposure to cyathostome contaminated pastures would express acquired resistance to infection. The assumption behind this hypothesis was that helminth-naïve ponies infected with cyathostomes would eliminate the infection using only innate immune responses. Whereas previously exposed ponies would eliminate the infection with acquired immune responses, and these would be more effective in ponies with longer exposure to cyathostomes. Thus, helminth-naïve animals would acquire …
