Rice Straw Fiber Polymer Composites: Thermal And Mechanical Performance, Fei Yao

LSU Doctoral Dissertations

Rice straw fiber can be considered as important potential reinforcing filler for thermoplastic composite because of its lignocellulosic characteristics. It is thus of practical significance to understand and predict the thermal decomposition process of rice straw fibers. A method proposed by Málek, Šesták, and co-workers was used to investigate and model thermal decomposition process of common natural fibers with detailed analysis on rice straw system. Assuming a global model occurring within the entire degradation of natural fibers with consideration of fiber as one pseudo-component, model can be used to describe both isothermal and non-isothermal degradation process of most selected fibers …

Matrix-Assisted Laser Desorption/Ionization Mass Spectrometry For The Analysis Of Collected Bioaerosols, Alton John Dugas

LSU Doctoral Dissertations

The goal of this dissertation was to demonstrate collection, detection and identification of microorganisms from bioaerosols using offline matrix-assisted laser desorption/ionization mass spectrometry (MALDI-MS) for the analysis of proteins. MALDI-MS intact bacteria techniques were adapted for use with an orthogonal MALDI quadrupole-time-of-flight mass spectrometer. Results indicate the instrument is capable of analyzing intact whole-cells. The first phase was to evaluate three bioaerosol samplers, an Andersen N6 single-stage impactor (AI), a cyclone impactor, and a vacuum filter system. The samplers collected test bioaerosols using a constructed bioaerosol exposure chamber (BEC). The BEC allowed all three samplers to operate in parallel. Each …

Numerical Simulations Of Flow And Mass Transport In Micro-Fluidic Components For Modular Bio-Analytic Chip Applications, Sudheer D. Rani

LSU Doctoral Dissertations

Microfluidics has received a great deal of attention in the past decade. The ability of modular microfluidic chips to miniaturize integrate chemical and biological systems (µTAS) can be greatly productive in terms of cost and efficiency. During the design of these modular devices, misalignment of materials, geometrical or both is one of the most common problems. These misalignments can have adverse effect in both pressure driven and electrokinetically driven flows. In the present work, Numerical Simulations have been performed to study the effect of material and geometrical mismatch on the flow behavior and species progression in microfluidic interconnects. In the …

The teaching of the specific language arts skills, listening, speaking, reading, and writing, as directed the the Comprehensive Curriculum is examined. Four first grade teachers from a large urban school district, from an original sixteen first grade teachers, are observed during the hour and a half literacy instruction block once a week over a period of four weeks. These same four teachers are interviewed one-on-one by the researcher during the two interview sessions. Three themes developed throughout the observation from all …

Cluster Kinetics Modeling Of Glassforming Materials, Lisa Ann Brenskelle

LSU Doctoral Dissertations

In this work, a new model relating temperature and pressure to dielectric relaxation or viscosity of a glassformer is developed. The model is based upon cluster kinetics, reaction-like mechanisms describing interactions between glassformer monomers and their clusters. Mathematical solutions of population balance equations for monomer and cluster lead to molar concentrations in terms of rate coefficients of the reaction-like mechanisms. These are then related to viscosity or dielectric relaxation time through free volume theory. The resulting equations are tested against data for a variety of pure glassformers, fragile, non-fragile, large, and small molecules over a wide range of temperatures, pressures, …

Fast Marching Methods - Parallel Implementation And Analysis, Maria Cristina Tugurlan

LSU Doctoral Dissertations

Fast Marching represents a very efficient technique for solving front propagation problems, which can be formulated as partial differential equations with Dirichlet boundary conditions, called Eikonal equation: $F(x)|\nabla T(x)|=1$, for $x \in \Omega$ and $T(x)=0$ for $x \in \Gamma$, where $\Omega$ is a domain in $\mathbb{R}^n$, $\Gamma$ is the initial position of a curve evolving with normal velocity F>0. Fast Marching Methods are a necessary step in Level Set Methods, which are widely used today in scientific computing. The classical Fast Marching Methods, based on finite differences, are typically sequential. Parallelizing Fast Marching Methods is a step forward for …

Dublin Core Metadata Harvested Through Oai-Pmh, Amy S. Jackson, Myung-Ja Han, Kurt Groetsch, Megan Mustafoff, Timothy W. Cole

University Libraries & Learning Sciences Faculty and Staff Publications

The introduction in 2001 of the Open Archives Initiative Protocol for Metadata Harvesting (OAI-PMH) increased interest in and awareness of metadata quality issues relevant to digital library interoperability and the use of harvested metadata to build "union catalogs" of digital information resources. Practitioners have offered wide-ranging advice to metadata authors and have suggested metrics useful for measuring the quality of shareable metadata. Is there evidence of changes in metadata practice in response to such advice and/or as a result of an increased awareness of the importance of metadata interoperability? This paper looks at metadata records created over a six-year period …

Governing Certain Things: The Regulation Of Street Trees In Four North American Cities, Irus Braverman

Journal Articles

Most sociolegal studies of the urban street focus on the human element. By focusing on the tree, my Article offers a unique perspective on the interrelations between various actors within the public spaces of modern North American cities. Situated at the intersection of legal geography, anthropology, and Science and Technology Studies, this Article demonstrates how natural artifacts function as technologies of governance, thereby masking crucial political interventions behind a natural facade. The tensions between nature and the city, as embedded in both the construction and the regulation of street trees, provide an unusual perspective on the management of urban populations …

Religion At A Public University, Gerard V. Bradley

Journal Articles

On March 6, 2007, the College of William & Mary announced a “compromise” solution to its polite civil war over the historic Wren Chapel. In a joint statement with President Gene Nichol, the Board of Visitors declared that permanent display of the Christian cross within the Chapel would resume. The cross would be moved, however, from its former place at center stage on the Chapel altar. Accompanying the elocated display would be a plaque “explaining the College's Anglican roots.” The compromise further provided that, when needed during certain worship services, the cross could be moved back to the altar. When …

The Memory Gap In Surveillance Law, Patricia L. Bellia

Journal Articles

U.S. information privacy laws contain a memory gap: they regulate the collection and disclosure of certain kinds of information, but they say little about its retention. This memory gap has ever-increasing significance for the structure of government surveillance law. Under current doctrine, the Fourth Amendment generally requires government agents to meet high standards before directly and prospectively gathering a target's communications. The law takes a dramatically different approach to indirect, surveillance-like activities, such as the compelled production of communications from a third party, even when those activities yield the same information as, or more information than, direct surveillance activities. Because …

Real-Time Implementation Of A Statcom On A Wind Farm Equipped With Doubly Fed Induction Generators, Wei Qiao, Ganesh K. Venayagamoorthy, Ronald G. Harley

Electrical and Computer Engineering Faculty Research & Creative Works

Voltage stability is a key issue to achieve the uninterrupted operation of wind farms equipped with doubly fed induction generators (DFIGs) during grid faults. This paper investigates the application of a static synchronous compensator (STATCOM) to assist with the uninterrupted operation of a wind turbine driving a DFIG, which is connected to a power network, during grid faults. The control schemes of the DFIG rotor- and grid-side converters and the STATCOM are suitably designed and coordinated. The system is implemented in real-time on a real time digital simulator. Results show that the STATCOM improves the transient voltage stability and therefore …

Notes On The Multiple Facets Of Immigration Federalism, Rick Su

Journal Articles

This symposium essay takes as its starting point the contestable position that some degree of immigration federalism is both constitutionally permissible and politically desirable. It suggests, however, that liberating the issue of immigration from the shadows of federal exclusivity does not necessarily tell us much about what a conceptual framework or legal jurisprudence of immigration federalism should or will actually be like. This is not solely a function of the difficulties inherent in incorporating principles of federalism into what is usually understood to be an exclusive federal field of immigration. Rather, it is also a consequence of the rifts and …

Section 524(G) Without Compromise: Voting Rights And The Asbestos Bankruptcy Paradox, S. Todd Brown

Journal Articles

Section 524(g) of the Bankruptcy Code was adopted to protect unknown future asbestos personal injury victims' rights and prospects for financial recovery. To serve these goals and satisfy the demands of due process, Section 524(g) provides two basic forms of virtual representation for future victims - requiring the appointment of an independent legal representative and aligning the interests of future victims with current claimants (75% of whom must approve any plan that invokes Section 524(g)). In recent years, however, the 75% super-majority vote requirement has been transformed into a veto power wielded by a small group of law firms, who …

Law And Economic Change During The Short Twentieth Century, John Henry Schlegel

Contributions to Books

Published as Chapter 16 in Cambridge History of Law in America, Volume 3: The Twentieth Century and After (1920–), Michael Grossberg & Christopher Tomlins, eds.

The brief recounting of the American economy in the twenties and thirties raises obvious questions about law and economic change. Economic change is the shift from one enacted, in both senses, understanding of economic life to another, in the case of the short twentieth century, from an associationalist economy to an impatient economy. This chapter explicates this economic change, and interrogates it in order to understand the role of law in its occurrence. Despite the …

The Supreme Court And The Politics Of Death, Stephen F. Smith

Journal Articles

This article explores the evolving role of the U.S. Supreme Court in the politics of death. By constitutionalizing the death penalty in the 1970s, the Supreme Court unintentionally set into motion political forces that have seriously undermined the Court's vision of a death penalty that is fairly administered and imposed only on the worst offenders. With the death penalty established as a highly salient political issue, politicians - legislators, prosecutors, and governors - have strong institutional incentives to make death sentences easier to achieve and carry out. The result of this vicious cycle is not only more executions, but less …

Estimation Of Earthquake Loss Due To Bridge Damage In The St. Louis Metropolitan Area: Part I - Direct Losses, Ronaldo Luna, David J. Hoffman, William T. Lawrence

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The risk associated with earthquake hazards on highway systems is dependent on the complexity of a network and its redundancy in providing traffic flow. Earthquake loss estimation studies can provide decision makers with an appreciation of the importance of having a highway network resistant to earthquakes and information to make the network resistant to these events. The direct economic loss was estimated for a major metropolitan area, St. Louis, for a series of earthquake scenarios. The primary component of the study was damage to bridges within the highway system. The study zone covers the St. Louis metropolitan area and its …

Development Of Ballistic Limit Equations For Dual-Wall Spacecraft Shielding: A Concise History And Suggestions For Future Development, William P. Schonberg

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

All earth-orbiting spacecraft are susceptible to impacts by orbital debris particles, which can occur at extremely high speeds and can damage flight- and mission-critical systems. The traditional damage mitigating shield design for this threat consists of a “bumper” that is placed at a relatively small distance away from the main “inner wall” of the spacecraft. The performance of a hypervelocity impact shield is typically characterized by its ballistic limit equation, which is typically drawn as a line of demarcation between regions of rear-wall perforation and no perforation; when graphically represented, it is often referred to as a ballistic limit curve. …

Katrina, Feminism, And Environmental Justice, Robert R.M. Verchick

Cardozo Journal of Equal Rights & Social Justice

The article examines the disproportionate impact of Hurricane Katrina on marginalized communities, particularly African Americans and women, through the lens of feminist theory and environmental justice. It argues that the disaster's effects were not random but rather the result of systemic inequalities rooted in race, gender, and class. The analysis emphasizes the need to address these disparities in disaster response and recovery policies to ensure justice and equity for all.

Credibility On The Internet: Shifting From Authority To Reliability, R. David Lankes

Faculty Publications

Purpose – This paper seeks to understand how users determine credibility in the internet environment from a conceptual level and the implications of these new methods of credibility determination on internet tools (primarily software) and services.

Design/methodology/approach – The author first examines the underlying reasons for increased dependence on the internet for information, using electronic commerce as a starting point. The central concept of “information self-sufficiency” is introduced and then examined through the lens of the internet and conversation theory.

Findings – The author finds that users are shifting from more traditional “authority” methods of credibility determination, where users cede …

Geo-Ontology Tools – The Missing Link, Jochen Albrecht, Laxmi Ramasubramanian, Brandon Derman

Publications and Research

Numerous authors have presented ontology building tools that have all been developed as part of academic projects and that are usually adaptations of more generic tools for geo-spatial applications. While we trust that these tools do their job for the special purpose they have been built, the GIScience user community is still a long way away from off-the-shelf ontology builders that can be used by GIS project managers. In this article, we present a comparative study of ontology building tools described in some twenty peer-reviewed GIScience journal articles. We analyze them from the perspective of two application domains, crime analysis …

Towards A Model Of Critical Ethics To Inform The Research Process In Postgraduate Research, Aidan Kenny

Level 3

he ethics narrative has become embedded in the contemporary research process, as evident in the emergence of Ethical Committees in faculty and both public and private organisations. Ethics have been codified, made visible and accessible as text artefacts in the forms of (both voluntary and regulatory) codes, statements, conventions, guidelines, principles, procedures, practices. In this short paper I explore this codification of ethics from the period post WWII, detailing some of the milestone text artefacts

International League Tables And Rankings In Higher Education: An Appraisal, Kathleen Lynch

Level 3

Universities have marketed themselves in the public sphere and justified public funding for their activities on the grounds that they serve the public good. They have traded on their Enlightenment inheritance that they are the guardians and creators of knowledge produced for the greater good of humanity in its entirety. They are seen and claim to be seen as the watchdogs for the free interchange of ideas in a democratic society; they claim to work to protect freedom of thought, including the freedom to dissent from prevailing orthodoxies.
