On The Witt Groups Of Schemes, Jeremy Allen Jacobson Jan 2012

On The Witt Groups Of Schemes, Jeremy Allen Jacobson

LSU Doctoral Dissertations

We consider two questions about the Witt groups of schemes: the first is the question of finite generation of the shifted Witt groups of a smooth variety over a finite field; the second is the Gersten conjecture. Regarding the first, we prove that the shifted Witt groups of curves and surfaces are finite, and that finite generation of the motivic cohomology groups with mod 2 coefficients implies finite generation of the Witt groups. Regarding the second, we prove the Gersten conjecture for the Witt groups in the case of a local ring that is essentially smooth over a discrete valuation …

Software Architectural Support For Tangible User Interfaces In Distributed, Heterogeneous Computing Environments, Cornelius Toole

LSU Doctoral Dissertations

This research focuses on tools that support the development of tangible interaction-based applications for distributed computing environments. Applications built with these tools are capable of utilizing heterogeneous resources for tangible interaction and can be reconfigured for different contexts with minimal code changes. Current trends in computing, especially in areas such as computational science, scientific visualization and computer supported collaborative work, foreshadow increasing complexity, distribution and remoteness of computation and data. These trends imply that tangible interface developers must address concerns of both tangible interaction design and networked distributed computing. In this dissertation, we present a software architecture that supports separation …

Function And Diversity Of The Ship, Trinity, And Tiger Shoal Complex, With Emphasis On Macrofauna And Spawning Blue Crabs (Callinectes Sapidus), Carey George Gelpi Jr.

LSU Doctoral Dissertations

The ecological and economic value of sandy shoals off the Louisiana coast is not well understood. During three years of comprehensive benthic sampling and environmental measurements I studied the Ship, Trinity, Tiger Shoal Complex (STTSC), which comprises changing and discrete benthic habitats including high relief sandy shoals, and muddier, mostly deeper off-shoal areas, prone to hypoxia. Benthic macrofaunal assemblages of shoals included endemic species, and shoal communities were significantly different from each other and the muddier offshoal habitat, contributing to northern Gulf of Mexico (GoM) regional biodiversity. Sand percentage was the most influential environmental parameter shaping macrofaunal community composition across …

Detection And Characterization Of Environmentally Persistent Free Radicals (Epfrs) In Soils And Sediments From Superfund Sites, Albert Leo N. Dela Cruz Jan 2012

Detection And Characterization Of Environmentally Persistent Free Radicals (Epfrs) In Soils And Sediments From Superfund Sites, Albert Leo N. Dela Cruz

LSU Doctoral Dissertations

Environmentally persistent free radicals (EPFRs) from combustion-generated PM have been demonstrated to form via reactions of molecular precursors with redox-active transition metals at 150-500C thermal reactions in a few seconds reaction times. While ambient temperatures are much lower, soils/sediments contain similar transition metals, and reaction times of contaminants in soils/sediments are years, rather than seconds. This questions whether EPFRs could be formed at ambient temperatures in soils/sediments from Superfund sites that are contaminated with hazardous materials. Superfund soils contaminated with PCP from Georgia and Montana, and sediments contaminated with PAHs from Washington. Using EPR spectroscopy, EPFR concentrations and structural assignments …

Mapping Of The Oil Window In The Eagle Ford Shale Play Of Southwest Texas Using Thermal Modeling And Log Overlay Analysis, Austin Pourciau Cardneaux Jan 2012

Mapping Of The Oil Window In The Eagle Ford Shale Play Of Southwest Texas Using Thermal Modeling And Log Overlay Analysis, Austin Pourciau Cardneaux

LSU Master's Theses

The Eagle Ford formation in South Texas has been an established hydrocarbon play since 2008. The Eagle Ford is considered an unconventional resource because it is a source, reservoir, and seal. Hydraulic fracturing and horizontal drilling have enabled this play. As drilling and production continue the limits of this play are being defined. The area between dry gas and wet gas/condensate has been known for some time since the initial production started in dry gas and moved up-dip. After the oil window was discovered, the contact between wet gas/condensate started to become more defined. Now companies are beginning to delineate …

Evaluation Of Growth Rates And Establishment Patterns Of Water-Elm (Planera Aquatica) And Baldcypress (Taxodium Distichum) In Response To Hydrologic And Climatic Conditions At Catahoula Lake, Louisiana, Sanjeev Joshi Jan 2012

Evaluation Of Growth Rates And Establishment Patterns Of Water-Elm (Planera Aquatica) And Baldcypress (Taxodium Distichum) In Response To Hydrologic And Climatic Conditions At Catahoula Lake, Louisiana, Sanjeev Joshi

LSU Master's Theses

Hydrologic alterations frequently lead to vegetation changes in floodplain ecosystems. In Louisiana, there has been an expansion of water-elm (Planera aquatica) and to a lesser extent baldcypress (Taxodium distichum) at Catahoula Lake, a Ramsar Wetland of International Importance. Water-elm and baldcypress both are flood tolerant species; baldcypress growth is known to be influenced by hydrologic conditions more than climate. The expansion of these woody trees has reduced herbaceous vegetation valuable for waterfowl. In this study, I tested two hypotheses that establishment of water-elm trees into the lake increased after the construction of water control structures in the nearby Black River …

Impact Of Teaching Style On Student Learning Of Evolution, Laurie Font Jan 2012

Impact Of Teaching Style On Student Learning Of Evolution, Laurie Font

LSU Master's Theses

Natural selection is a topic that is laden with misconceptions. These misconceptions are often not addressed, and students can leave a biology classroom with the same incorrect ideas that they entered with. These misconceptions can be identified and addressed by using the Concept Inventory of Natural Selection (CINS). Furthermore, by teaching using methods that encourage hands-on, inquiry based techniques, students are more apt to reconcile these misconceptions and have a deeper understanding of the natural selection process. The goal of my research was to show a positive correlation between reduction in student misconceptions about natural selection and inquiry based activities. …

Focus Question Effect On Dynamic Thinking In A Concept Map, Blake John Orgeron Jan 2012

Focus Question Effect On Dynamic Thinking In A Concept Map, Blake John Orgeron

LSU Master's Theses

A concept map is an educational tool designed to help identify, represent, and categorize relationships between different ideas relating to an overall concept. Relationships or transitions between the ideas are created by students and can either be static or dynamic. Static transitions help to describe, define, and organize knowledge for a given domain. Dynamic transitions show how a change in quantity, quality, or state in one concept causes change in quantity, quality, or state in the other concept. The focus question of the map directs student input of the concepts and ultimately determines what types of transitions are used. The …

The Effects Of Carbon On Nitrogen Transformations In Restored Wetland And Wastewater Soils, Jared M. Theriot Jan 2012

The Effects Of Carbon On Nitrogen Transformations In Restored Wetland And Wastewater Soils, Jared M. Theriot

LSU Master's Theses

Since the industrialization of the Haber-Bosch process in the 1940’s, anthropogenic activity has nearly doubled the Earth’s nitrogen fixation. Furthermore, nitrate has become the number one groundwater contaminant in the United States and has harmful effects such as eutrophication, algal blooms, and pollution of drinking water. Soils from two sites influenced by high nitrate loading were examined to determine their biogeochemical integrity. First, the Loosahatchie Bar, located northwest of Memphis, Tennessee, is influenced by excess surface water nitrate loading by the Mississippi River. The Loosahatchie Bar is a newly restored wetland that now has similar hydrologic influence to an upstream …

Mathematical Modeling In The High School Classroom, Selena Oswalt Jan 2012

Mathematical Modeling In The High School Classroom, Selena Oswalt

LSU Master's Theses

Mathematical modeling is the procedure whereby students apply mathematical concepts learned in class to new and unfamiliar situations. A modeling task is a mathematically-rich problem that engages students in mathematical thinking, drawing upon their previously learned knowledge and supporting their understanding of the mathematical concepts currently being covered. Modeling requires students to assign meaning to the mathematical concepts and to extend the concepts beyond rote learning. In order for students to be successful in a classroom that is centered around the idea of mathematical modeling, the students must be taught how to collaborate with other students, persevere through challenging problems, …

Nitrogen Biogeochemistry In A Restored Mississippi River Delta: A Modeling Approach, Benjamin Lee Branoff Jan 2012

Nitrogen Biogeochemistry In A Restored Mississippi River Delta: A Modeling Approach, Benjamin Lee Branoff

LSU Master's Theses

There is evidence that significant reductions (about 50%) in surface water nitrate concentrations within coastal deltaic wetlands receiving diverted Mississippi River water can be contributed to denitrification. Yet there is also contrasting evidence that other processes could be responsible for this nitrate reduction. As Louisiana plans the implementation of major Mississippi River sediment diversions, a thorough understanding of nitrogen dynamics is necessary to reduce risks of coastal eutrophication and offshore hypoxia. A mechanistic numerical computer model has been developed to simulate nitrogen biogeochemistry within the wetlands of the prograding Wax Lake Delta. This model is calibrated to observed fluxes within …

Studies On A Dirhodium Tetraphosphine Hydroformylation Catalyst, Darina Polakova Jan 2012

Studies On A Dirhodium Tetraphosphine Hydroformylation Catalyst, Darina Polakova

LSU Doctoral Dissertations

The dirhodium tetraphosphine catalyst [Rh2(nbd)2(rac-et,ph-P4)](BF4)2 was investigated in acetone and water/acetone in order to explain better hydroformylation results in the latter solvent. In-situ NMR spectroscopy showed slower degradation in water/acetone. Less tendency to form penta/hexacarbonyl complexes in water/acetone was shown by 31P{1H} NMR and FT-IR. A pH decrease and hydroformylation studies in presence of a base indicated formation of a monocationic monohydride species. A new reaction mechanism was suggested that takes into account the observed differences from the acetone solvent system. The presence of water enabled production of hydride species when the dirhodium catalyst was exposed to CO gas. We …

Strongly Correlated Electron Behavior In Transition Metal Intermetallics: Enhanced Thermoelectricity And Quantum Criticality In Fega₃ And Superconductivity In Nibi₃, Neel Saman Kumara Haldolaarachchige

LSU Doctoral Dissertations

TGa3 (T = Fe, Ru & Os) and RuIn3 are a class of isostructural intermetallic binary compounds with interesting physical and structural properties. These materials are non-magnetic, narrow band gap semiconductors with large n-type thermopower below room temperature. Chemical doping drastically changes physical properties and thermoelectric properties enhances by large percentage over the pure compounds. An important structural feature of FeGa3 is the fact that the four Fe atoms per unit cell exist as two Fe-Fe dimers. The nonmagnetic (NM) ground state of FeGa3 may be a consequence of the dimer spins being aligned in an antiparallel singlet state. We …
