Extrahepatic 25-Hydroxylation Of Vitamin D3 In An Engineered Osteoblast Precursor Cell Line Exploring The Influence On Cellular Proliferation And Matrix Maturation During Bone Development, Shelley S. Mason, Sean S. Kohles, Shelley R. Winn, Randy D. Zelick

Biology Faculty Publications and Presentations

Osteoblastic precursors experience distinct stages during differentiation and bone development, which include proliferation, extracellular matrix (ECM) maturation, and ECM mineralization. It is well known that vitamin D plays a large role in the regulation of bone mineralization and homeostasis via the endocrine system. The activation of vitamin D requires two sequential hydroxylation steps, first in the kidney and then in the liver, in order to carry out its role in calcium homeostasis. Recent research has demonstrated that human-derived mesenchymal stem cells (MSCs) and osteoblasts can metabolize the immediate vitamin D precursor 25- dihydroxyvitamin D₃(25OH₂D₃) to the active steroid 1α,25-dihydroxyvitamin D₃ …

Determining A New Alignment Scoring Matrix For Disordered Proteins, Adam Handen

Theses

Intrinsically disordered proteins (IDPs) are polypeptide sequences that do not form a rigid three dimensional structure when isolated in the cytosol of the cell. These sequences are very common in most genomes, and usually are involved in many protein-protein interactions. IDPs also play a key role in many diseases, including cancer and Huntington's disease. However, IDPs are difficult to study because of their amorphous shape, high mutation rate, and unique amino acid composition. These obstacles make homology studies especially difficult.

This study focused on generating a new substitution matrix designed to aid in homology studies of IDPs. The matrix was …

Measuring The Racial Unevenness Of Law School, Jonathan Feingold, Doug Souza

Faculty Scholarship

In "Measuring the Racial Unevenness of Law School," Jonathan Feingold and Doug Souza introduce and analyze the concept of racial unevenness, which refers to the particularized burdens an individual encounters as a result of her race. These burdens, which often arise because an individual falls outside of the racial norm, manifest across a spectrum. At one end lie obvious forms of overt and invidious racial discrimination. At the other end, racial unevenness arises from environmental factors and institutional culture independent from any identifiable perpetrator. As the authors detail, race-dependent burdens can arise in institutions and communities that expressly promote racial …

A Study Of Traditional Activities In The Exit Glacier Area Of Kenai Fjords National Park, Douglas Deur, Karen Brewster, Rachel Mason

Anthropology Faculty Publications and Presentations

Kenai Fjords National Park (KEFJ) occupies roughly 1,760 square miles on the Kenai Peninsula in southcentral Alaska. Sitting adjacent to the community of Seward, the park was established in 1980 under the Alaska National Interest Lands Conservation Act of 1980 (ANILCA). The central portion of the park contains the Harding Icefield, from which no fewer than 38 active glaciers exit into valleys and tidewater locations surrounding the park. Of these glaciers, Exit Glacier is the most publicly accessible, and the only park glacier with road access from the town of Seward. A number of individuals and families from the Seward …

Modeling Temporal And Spatial Variations In Dissolved Oxygen In Amite River, Vahid Zahraeifard

LSU Doctoral Dissertations

A watershed-based modeling framework is developed in this dissertation for simulating temporal and spatial variations in DO in lowland rivers with organic-rich fine-grained sediment. The modeling framework is based on three major contributions/new models, including (1)VART-DO model for improved estimation of reaeration coefficient (K2) in natural streams, (2)VART-DOS model for simulation of temporal variations in DO in response to sediment resuspension, and (3)VART DO-3L model for simulation of spatial variations in DO. A major advantage of VART-DO model is the capability of simulating DO exchange across the water-sediment interface through the hyporheic exchange mechanism in addition to the air-water exchange. …

Induction Motors With Rotor Helical Motion, Ebrahim Amiri

LSU Doctoral Dissertations

Performance analysis of the twin-armature rotary-linear induction motor, a type of motor with two degrees of mechanical freedom, is the subject of this dissertation. The stator consists of a rotary armature and linear armature placed aside one another. Both armatures have a common rotor which can be either solid or cage rotor. The rotor can move rotary, linearly or with helical motion. The linear motion generates dynamic end effect on both linear and rotary armature. Modeling such an effect in rotary armature is a significant challenge as it requires a solution considering motion with two degrees of mechanical freedom. In …

The results identified common relationships between the two modes of reaction atmospheres, as well as some differences. While some products were favored by an inert regime, some were favored under an oxidative regime. Oxidative pyrolysis …

Spatial Structure And Dynamics Of The Plant Communities In A Pro-Grading River Delta : Wax Lake Delta, Atchafalaya Bay, Louisiana, Melissa Carle

LSU Doctoral Dissertations

River deltas are dynamic depositional environments that are controlled to varying degrees by coastal and fluvial forces. Plant communities in deltas respond to many of the same allogenic forces that shape delta geomorphology. This study examines the factors that influence plant community development, productivity, and species distributions in the Wax Lake delta, a young, actively pro-grading river delta in coastal Louisiana, USA. A species distribution map created using high-resolution 8-band WorldView-2 imagery was found to have an overall accuracy of 75 percent. Classification tree analysis suggested that most of the observed variation in plant species distributions within the delta can …

Evaluating Abiotic Influences On Soil Salinity Of Inland Managed Wetlands And Agricultural Fields In A Semi-Arid Environment, Drew Nathan Fowler

LSU Master's Theses

Agriculture and moist-soil management are important management techniques used on wildlife refuges to provide adequate energy for migrant and wintering waterbirds. However, in arid systems, the presence and accumulation of soluble salts throughout the soil profile can limit total biomass production of wetland plants and agronomic crops and thus jeopardize meeting waterbird energy needs. It is unknown how moist-soil management and traditional agriculture practices influence the accumulation and distribution of soluble salts of soil profiles. In this study of an arid wetland ecosystem, I determine: 1) the effect of long-term, distinct surface hydrologic regimes associated with moist-soil management and agricultural …

Evaluating Quaternary Glacial Till Sheet Volume And Duration Of Grounding Events Using Sediment Flux Calculations In The Eastern Basin Paleotroughs, Ross Sea, Anarctica, Logan Gregory Kirst

LSU Master's Theses

A sequence of three seismically-resolvable, back-stepping grounding zone wedges (GZWs) within the Glomar-Challenger Basin paleo-ice-stream trough is conventionally interpreted to have been deposited by the West Antarctic Ice Sheet (WAIS) since the end of the Last Glacial Maximum (LGM). For this to be true, there would have to have been voluminous GZW deposition via fast moving ice streams with high sediment flux during the short timeframe since the WAIS retreat began at 11 Ka 14C BP and when the WAIS moved south of Roosevelt Island at 3.2 Ka BP. In contrast to this interpretation of how the near-surface stratigraphy relates …

Ecosystem Metabolism In Coastal Plain Streams Of Southeast Louisiana : Environmental And Watershed Effects, Jonathan L. West

LSU Doctoral Dissertations

Since its introduction in 1956, the use of open-system, diel dissolved oxygen curves for estimating the components of ecosystem metabolism in the lotic setting have been important in determining the current ecosystem theory of streams, both spatially among multiple systems and longitudinally within the same system, as well as identifying potentially impaired systems, especially when contrasted with streams considered unimpaired. Several factors have been identified as controls on both components of ecosystem metabolism and include light, nutrients, and stable substrates for gross primary production (GPP) and a source of organic matter (OM) for ecosystem respiration (ER). Stream size is important …

Alappat Redux: Support For Functional Language In Software Patent Claims, Andrew Chin

Faculty Publications

The Federal Circuit has suggested in some recent cases that any algorithm can serve as adequate structural support for a means-plus-function element in a software patent claim under § 112(f). A recent proposal by Mark Lemley fully endorses this proposition and seeks its broader application. The concept of an algorithm, however, is too slippery to serve as the basis for such a rule. In this Article, I argue that this overreliance on the algorithm concept originated in a revisionist gloss on the Federal Circuit's 1994 Alappat decision. Informed by a closer reading of what Alappat actually has to say about …

Academic Support Of Division I Head Coaches: Perceptions Of Student-Athletes, Mikaela M. Raddatz

Theses and Dissertations--Educational Policy Studies and Evaluation

Intercollegiate athletics in the United States have continuously become more commercialized, pressuring athletics departments and coaches to produce winning teams. The commanding expectations for successful programs have been thought to take away from the academic mission of colleges and universities, focusing efforts on athletics over academics. This phenomenon has been examined, but the role head coaches play in support of student-athlete academics has yet to be explored.

The purpose of this study is to measure student-athlete perception of academic support from Division I head coaches. Current literature demonstrates the strong influence of coaches on student-athletes, but the effect in the …

The Influence Of Race And Socioeconomic Status On Routine Screening Practices Of Physician Assistants, Deshana Ann Collett

Theses and Dissertations--Educational Policy Studies and Evaluation

Health disparities in minorities and those of low socioeconomic status persist despite efforts to eliminate potential causes. Differences in the delivery of services can result in different healthcare outcomes and therefore, a health disparity. Some of this difference in care may attribute to discrimination resulting from clinical biases and stereotyping which may provide a possible source for the persistence of health disparities. Health disparities may occur because the delivery of services at some level is inadequate. Disparities resulting from the quality and quantity of care delivered by a practitioner result in differentiated delivery of healthcare, thus unequal health outcomes. The …

California Turnaround Schools: An Analysis Of School Improvement Grant Effectiveness, Khalil Graham

Theses and Dissertations--Educational Leadership Studies

The purpose of this study was to evaluate the effectiveness of School Improvement Grants (SIGs) in the state of California (CA) in increasing student achievement using the turnaround implementation model. The American Recovery and Reinvestment Act of 2009 (ARRA) included educational priorities focused on fixing America’s lowest achieving schools. SIGs (i.e., up to $2 million per school annually over 3 years) to the nation’s persistently lowest achieving public schools required schools accepting these awards to implement a federally prescribed school-reform model. Of these models, the school turnaround model is the most aggressive and least used. Using data from CA, the …

Characterization Of Epibenthic And Demersal Megafauan At Mississippi Canyon 252 Following The Deepwater Horizon Oil Spill, Marla Maxine Valentine

LSU Master's Theses

Increased demand for new sources of oil and gas has resulted in an expansion of drilling into deeper waters. With this exploratory drilling come increased risks, which were realized on April 20, 2010 when the blow out preventer on the Macondo Well failed, resulting in the release of a large quantity of oil and gas into the Northern Gulf of Mexico from a bathypelagic source. This unprecedented environmental disaster was coined the Deepwater Horizon Oil Spill by the popular news media. In the months that followed the spill, the lack of knowledge about the pre-spill condition of deep-sea communities in …
