Quasi-Exact Helical Cone Beam Reconstruction For Micro Ct, Jicun Hu, Robert C. Molthen, Roger Johnson, Steven Haworth, Christopher Dawson

Biomedical Engineering Faculty Research and Publications

A cone beam micro-CT system is set up to collect truncated helical cone beam data. This system includes a micro-focal X-ray source, a precision computer-controlled X-Y-Z-theta stage, and an image-intensifier coupled to a large format CCD detector. The helical scanning mode is implemented by rotating and translating the stage while keeping X-ray source and detector stationary. A chunk of bone and a mouse leg are scanned and quasi-exact reconstruction is performed using the approach proposed in J. Hu et al. (2001). This approach introduced the original idea of accessory paths with upper and lower virtual detectors having infinite axial extent. …

Cfd Simulations Of Critical Components In Fuel Filling Systems, R. Banerjee, X. Bai, D. Pugh, Kakkattukuzhy M. Isaac, D. Klein, J. Edson, W. Breig, L. Oliver

Mechanical and Aerospace Engineering Faculty Research & Creative Works

A comprehensive study is reported on the dynamics of critical components in the refueling process for passenger cars and light trucks. Nozzle, filler pipe, recirculation tube, tank, and canister are investigated. CFD simulations are conducted for flow rates of 4 liters/min (lpm) to 80 lpm for gasoline and up to 120 lpm for diesel fuel. Tank pressure, identified as a critical parameter controlling flow performance, is measured and utilized as a boundary condition. Flow simulation in a carbon canister, accomplished by treating the adsorbing carbon as a porous medium, indicates pressure drops which are in good agreement with published experimental …

Toward The Formation Of "Innocence Commissions" In America, Barry C. Scheck, Peter J. Neufeld

Articles

The article advocates for the establishment of "innocence commissions" to investigate and address wrongful convictions in the U.S. criminal justice system. Drawing parallels to the National Transportation Safety Board (NTSB), which investigates transportation accidents, the authors propose that these commissions would identify systemic defects leading to wrongful convictions and recommend reforms to prevent future miscarriages of justice. They emphasize the need for independence, subpoena power, and public accountability to ensure the commissions' effectiveness.

(Dis)Embedded Women, Rhoda E. Howard-Hassmann

Political Science Faculty Publications

The central question we were asked to address in the Michigan Journal of International Law's Symposium, "Dueling Fates," was, "Which international legal approach more effectively protects women's rights, the collective or the individual?" I am a political sociologist, without legal training, although I have been publishing in the field of international human rights (including women's rights) since 1980. This Article will focus on some underlying assumptions about the nature of society, and women's roles in it, that are pertinent to this central question.

The position argued in this Article is that women's rights are individual rights. To explain this position, …

Development Of An Alternate Curriculum For Bachelor Degree Completion Students In The Lead Program At Ohio Dominican College, William A. Vensel

Abraham S. Fischler College of Education ETD Archive

In the Learning Enhanced Adult Degree (LEAD) program at Ohio Dominican College (ODC), a cohort based accelerated delivery format, students who complete the Associate of Science (AS.) degree had only one bachelor's degree program to choose from, the B.S. in Business Administration. Because Ohio Dominican is a bachelor degree granting institution, classified as Baccalaureate General by the Carnegie Commission, it is desirable to see all enrolled students through to the bachelor degree. The problem addressed by this practicum was that with only one degree program to choose from at the bachelor level, retention of AS. students who desired the accelerated …

Abraham S. Fischler College of Education ETD Archive

The Family Health Branch of the Georgia Division of Public Health has been going through a transition by changing its mode of operation from an administrative to a facilitative and supportive role. There have been several changes in managers of Offices within the Branch, along with reduction in staff at all levels. Some program managers from the Office of Infant and Child Health spend a great portion of their time out of the office doing site visits, attending meetings or presenting workshops. During their absence no one is available to address specific issues related to their programs. An inter-programmatic training …

Nutrient Profile, Functional Properties, And Microstructure Of Dried Waste Milk Products For Use As A Potential Animal Feed, Ronald I. Thompson

LSU Doctoral Dissertations

A study was conducted to determine the feasibility of concentrating the wastewater of a butter/powder factory for use as an animal feed. Two concentrated products were evaluated: recovered milk product (RMP), which is the direct factory waste stream; and formulated recovered milk product (FRMP), which is a product made by combining RMP and separator de-sludge in a 3:1 ratio. Three pilot scale dryer systems were used to concentrate the product: a spray dryer, a roller dryer, and a pulse combustion dryer. Dried samples were analyzed for fat, moisture, protein, ash, nitrates, chloride, pH, calcium, phosphorus, sodium and amino acids. Values …

Service Learning: A Study Of Administrators' Goals At A Research I University, Christy Sanders

LSU Doctoral Dissertations

This case study explored the administrators' goals of a service learning program at a Research I university. This research was aimed at discovering administrators' goals and determining whether or not these goals were achieved, as perceived by students, administrators, community service agency directors, and faculty members. A structured, tape-recorded interview was used to gather data from participants in all groups. Barriers to implementation of service learning by faculty, students, and administrators included time constraints, lack of institutional support and lack of clarity as to what constituted service learning. University engagement in service learning was defined as the process by which …

An Argument For Tax Reform Based On Judeo-Christian Ethics, Susan Pace Hamill

Articles

This article applies the moral principles of JudeoChristian ethics as a basis for urging the citzens of Alabama to insist that the state and local tax structure be reformed This article first empirically documents that Alabamas state and local tax structure harshly burdens the poorest Alabamians through regressive income and sales taxes This article then proves that Alabamas lowest property taxes per capita in the nation leaves the state and local governments unable to fund minimum needs such as education thereby denying the poorest Alabamians a minimum opportunity to improve their lives An original empirical study of the relative property …

Molecular Phylogeny Of Melanospora And Diaporthales, And Population Genetics Of Dogwood Anthracnose Fungus, Ning Zhang

LSU Doctoral Dissertations

Unresolved phylogenetic problems in pyrenomycetes and population structure of an asexual plant pathogen (Discula destructiva) were investigated. Analyses based on DNA sequences of nuclear encoded small and large subunit RNA genes (SSU and LSU nrDNA) and deduced amino acid sequences of a subunit of RNA polymerase II gene (RPB2) indicated that five genera previously considered in Ceratostomataceae of Sordariales were related to Hypocreales. Melanospora (including the type) and a genus of Ceratostomataceae formed a basal clade, but monophyly of the five genera and of the genus Melanospora was rejected. Discula destructiva and four other Discula species were derived from within …

Numerical Reservoir Characterization Using Dimensionless Scale Numbers With Application In Upscaling, Djuro Novakovic

LSU Doctoral Dissertations

Dimensionless space provides a tool for analyzing the behavior of complex systems described by mathematical relationships. The limited application of dimensionless variables in numerical reservoir simulation and experimental design motivated the development of a complete set of dimensionless scaling groups. Inspectional analysis yielded 8 dimensionless groups completely describing the flow system. Further analysis of fluid interaction reduced the number of dimensionless groups to 7. The newly developed dimensionless equations and groups were used for analytical and numerical reservoir characterization, quantifying the behavior of differential and difference equations employed in fluid flow in three-dimensional porous media. The behavior of the dimensionless …

Reconceiving Curriculum: An Historical Approach, Stephen Shepard Triche

LSU Doctoral Dissertations

This dissertation reconceives curriculum through an historical approach that employs Ludwig Wittgenstein’s later philosophy. Curriculum is more than the knowledge taught in school. Curriculum, as I a theorist conceives it, is concerned with the broader intellectual and ideological ways a society thinks about education. Hence, the current school curriculum’s focus on specific learning outcomes offers a limited view of the knowledge fashioned by a society, thereby offering an intellectual and social history that is highly selective. Wittgenstein’s concept of “language-games” offers curricularists a way to re-include some of these stories. The concept of curriculum emerges at the end of the …

The Greek Sophists : Teachers Of Virtue, David Dwyer Corey

LSU Doctoral Dissertations

This dissertation is a study of the Greek sophists as teachers of aretê (virtue or human excellence) and a study of the conflict between sophistic and Socratic political values as portrayed in the dialogues of Plato. The first section offers a new definition of the term "sophist" based on ancient sources and attempts to present as clear a picture as is historically possible of the sophists' activities. The second section examines and evaluates Plato's criticisms of the sophists drawing attention especially to the dependence of certain criticisms upon a questionable set of epistemological assumptions about the role of knowledge in …

The Culture Of Crime: Representations Of The Criminal In Eighteen-Century England, Daniel Gonzalez

LSU Doctoral Dissertations

This dissertation explores how literary criminal narratives reflected public anxieties over the increasing commercialization of England during the early eighteenth century. It accounts for the popularity of the criminal in literature as well as public concerns about commercialization and the individuality it encouraged, revealing how these concerns were expressed in the most popular form of criminal narrative in this era, the criminal biography. Chapters on the criminal narratives of John Bunyan, Daniel Defoe and John Gay reveal how the criminal narrative functioned as a means of critiquing a developing commercial society in England. Bunyan first employs the formula of the …

La Poetique Du Paysage Dans L'Oeuvre D'Edouard Glissant, De Kateb Yacine Et De William Faulkner, Nabil Boudraa

LSU Doctoral Dissertations

This dissertation examines the different ways in which Edouard Glissant, Kateb Yacine and William Faulkner combine landscape, history and identity in their work. The depiction of landscape in literature is not new, but the French Romantics in the 19th century, for instance, tended to describe the beauty of landscape without conceiving any rapport between landscape and humankind, and thus created a gap between the two. For Kateb and Glissant, landscape is also a witness of History. The (hi)story of their respective communities has been confiscated and shattered by the respective colonizers, hence the necessity to recreate it through the poetics …

The Impact Of Gruesome Evidence On Mock Juror Decision Making : The Role Of Evidence Characteristics And Emotional Response, Robert J. Nemeth

LSU Doctoral Dissertations

Two experiments were conducted to investigate the effects of gruesome evidence on mock jurors? decisions in a simulated capital trial. The first experiment was designed as a replication and extension of Douglas, Lyon, and Ogloff (1997), who found that mock jurors who were presented with gruesome photographic evidence were nearly twice as likely to convict the defendant than participants who did not see the gruesome evidence. In Experiment 1, gruesome evidence was manipulated in two ways: photographic evidence (low gruesome, highly gruesome, or control photographs) and verbal testimony (low gruesome vs. highly gruesome). Neither photographic evidence nor testimony had an …

Prophet Singer: The Voice And Vision Of Woody Guthrie, Mark Allan Jackson

LSU Doctoral Dissertations

This project discusses the cultural and political significance of a number of lyrics by songwriter and political activist Woodrow Wilson "Woody" Guthrie. By drawing on both the singer's personal experiences and relevant American history, I lay out how larger political and cultural forces in society impacted Guthrie's songs. Although this work focuses primarily on his lyrics, my dissertation also draws on his interviews, commercial recordings, drawings, and other writing. Since much of the writing discussed in this work comes from archival collections at the Smithsonian Institution, the Library of Congress, and the Woody Guthrie Archives, I have covered a wider …

No Place To Die: The Poetics Of Roadside Sacred Places In Mexico, Daniel Raymond Weir

LSU Doctoral Dissertations

Roadside death memorials are a response to the sudden, tragic death of a loved one; and are appearing with increasing regularity in developed and developing countries across the globe. In Mexico, however, wayside memorials and shrines of religiosity are a centuries-old tradition. This work, an effort to understand why the exact location of a person’s death is so important that a sacred place must be created where no place is intended, is basic and exploratory research. A multi-method, and cross-disciplinary case study, based upon the author’s fieldwork in Mexico, produces massive data and constitutes a robust explanatory triangulation. A geographic …

The Impact Of Institutional Stock Ownership On A Firm's Earnings Management Practice: An Empirical Investigation, Santanu Mitra

LSU Doctoral Dissertations

This study examines whether institutional investor shareholdings inhibit firm managers from engaging in earnings management practice. It investigates the empirical association between discretion/flexibility available to managers in managing abnormal non-cash working capital accruals and institutional stock ownership for a sample of 386 New York Stock Exchange firms over a period of 8 years, from 1991 through 1998. The differential institutional influence on the level of accrual management of firms having different information environment, S&P 500 versus non S&P 500, is also examined to see whether the difference in information environment of these two sets of firms has any effect on …
