Implications Of Geothermal History On Microbial Gas Generation And Coalbed Methane Production In The Ninilchik Field, Cook Inlet Basin, Alaska, Eric M. Hart Jan 2012

Implications Of Geothermal History On Microbial Gas Generation And Coalbed Methane Production In The Ninilchik Field, Cook Inlet Basin, Alaska, Eric M. Hart

LSU Master's Theses

Coalbed methane (CBM) production operations atop the Ninilchik anticline of Cook Inlet, Alaska pose intriguing questions regarding the nature of biogenic gas generation in a thermally complex forearc basin setting. This thermal complexity stems, in part, from its up to 30,000 ft thick Tertiary section, comprised of braided stream alluvium and expansive, interbedded coal deposits. Rapid accumulation of cold, glacial strata is documented as being capable of regionally suppressing the elevated heat flux values expected within a forearc basin. In addition, beds with high organic content, such as the coal layers, act as natural insulators from basinal heat flux and …


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 …


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 …

Artificial Oyster Reefs In The Northern Gulf Of Mexico: Management, Material, And Faunal Effects, Jessica Nicole Furlong

LSU Master's Theses

Artificial oyster reefs seek to restore reef ecosystem services, such as water filtration, shoreline protection, and habitat for nekton. This study established three objectives to address the dispersed nature of artificial reef information in the Gulf of Mexico (GoM) and lack of post-construction monitoring assessments. First, to document the extent of activities in the GoM, we developed a database of all inshore artificial oyster reefs created for restoration purposes. Of the 422 reefs in the resultant database, a third or less provided records of entities involved (27%), restoration goals (24%), area (20%), monitoring efforts (15%), relief (9%), and costs (8%). …


Psychometric Re-Evaluation Of The Spiritual Support Scale, Angela M. Bowman Jan 2012

Psychometric Re-Evaluation Of The Spiritual Support Scale, Angela M. Bowman

LSU Master's Theses

Informal caregivers provide a substantial amount of emotional, financial, physical, and social support to their loved ones with Alzheimer’s disease. Alzheimer’s caregivers often report immense levels of burden, which are associated with the demands of their caregiving duties. Caregivers mediate this burden through various means of coping, including spiritual support. Individuals who successfully manage the negative stressors related to Alzheimer’s caregiving are often highly resilient. The purpose of this study was to re-evaluate the psychometric properties of the Spiritual Support Scale among a sample of Alzheimer’s caregivers. The Spiritual Support Scale was initially utilized to measure spiritual coping among a …

The Use Of A Mixed Chlorella Cyanobacteria Culture As A Protein Source For Aquaculture, Marjan Sadat Mohtashamian Jan 2012

The Use Of A Mixed Chlorella Cyanobacteria Culture As A Protein Source For Aquaculture, Marjan Sadat Mohtashamian

LSU Master's Theses

The increase in the global demand for fish feed in the last decades has resulted in the over exploitation of natural resources to produce more fishmeal supplies for aquaculture industry. The supply issues and high prices of fishmeal products have raised the incentives to seek for suitable alternatives to replace fishmeal protein. As a by-product of biofuel production process, residual microalgal biomass may be a low cost feed ingredient to the aquaculture diet. The potential of the use of a post lipid extraction Chlorella vulgaris/Leptolyngbya sp. Co-Culture (Louisiana co-culture) as a protein source in aquaculture feeds could help offset fishmeal. …


Frp Stiffener Efficiency Coefficient For Sbs Shear Strengthening Applications, Hamed Babaizadehroshanfekr Jan 2012

Frp Stiffener Efficiency Coefficient For Sbs Shear Strengthening Applications, Hamed Babaizadehroshanfekr

LSU Master's Theses

The use of composite materials such as Fiber Reinforced Polymer (FRP) to strengthen concrete structures has surged during the past two decades as an alternative for conventional methods of structural strengthening and repair. FRP materials are light and relatively easy to install. They are noncorrosive, durable and less vulnerable to environmental conditions in comparison to other construction and retrofitting materials. The knowledge and applications of composites for strengthening steel structures are relatively smaller when compared to concrete strengthening applications. Strengthening-By-Stiffening (SBS) is a new strengthening alternative that was developed at Louisiana State University. SBS has proven to be a practical …


The Effects Of Spinosad On Culex Quinquefasciatus (Diptera: Culicidae) And Non-Target Insect Species, Owen Mcbride Jones Jan 2012

The Effects Of Spinosad On Culex Quinquefasciatus (Diptera: Culicidae) And Non-Target Insect Species, Owen Mcbride Jones

LSU Master's Theses

Spinosad is a relatively new insecticide with a unique mode of action that is being evaluated for control of larval mosquitoes. Whereas a number of toxicological studies have measured effects of spinosad on various mammals, fish, birds, and terrestrial arthropods, fewer studies have been conducted on the effects of spinosad on non-target aquatic insect species. Such studies are important as these species might be found in the same environments as mosquito larvae targeted for control. A neighborhood pond was surveyed to find a representative species of mosquito as well as other common aquatic insects with which to examine susceptibility to …


Variations In Pore Water Salinities Above And Below Allochthonous Salt Sheets In The Deepwater Gulf Of Mexico: Implications For Mechanisms Of Solute Transport, Miles Alexander Mccammon Jan 2012

Variations In Pore Water Salinities Above And Below Allochthonous Salt Sheets In The Deepwater Gulf Of Mexico: Implications For Mechanisms Of Solute Transport, Miles Alexander Mccammon

LSU Master's Theses

Spatial variations in salinity of pore waters in marine sediments provide useful information on processes and rates of subseafloor fluid flow and solute transport, particularly if there are evaporites in the section. Pore water salinities were determined for 18 drill holes which penetrated allochthonous salt bodies in 12 widely-scattered protraction blocks on the Louisiana offshore continental shelf and slope. Salinities were calculated from Log ASCII Standard-Logging While Drilling (LAS-LWD) logs using the Revil et al. (1998) dual-conductivity technique. The sites represent a wide range of field settings. Water depths range from 30 to 1990 m, depths to the top of …


Seeing The Divine: The Origin, Iconography, And Content Of Santa Pudenziana's Apse Mosaic, Rebecca Franzella Jan 2012

Seeing The Divine: The Origin, Iconography, And Content Of Santa Pudenziana's Apse Mosaic, Rebecca Franzella

LSU Master's Theses

When Christian artwork expanded into the grand, newly constructed Christian basilicas of the fourth century, new iconography emerged. The apse was a focal point of the basilica’s interior and provided a novel space for artistic decoration. The church of Santa Pudenziana, located in Rome, contains the earliest surviving apse decoration in a Christian basilica. Shown here is a depiction of Christ surrounded by his apostles. This figural arrangement is familiar because of previously established pagan and Christian imagery. However, at S. Pudenziana, and for the first time in Christian art, four angelic figures and the Heavenly Jerusalem appear in the …


Commuting Patterns And Labor Markets: A New Regional Classification For Louisiana, Deepa Acharya Jan 2012

Commuting Patterns And Labor Markets: A New Regional Classification For Louisiana, Deepa Acharya

LSU Master's Theses

Regional classification and labor market study form an important part of any regional development efforts. Successful formation and implementation of developmental policies for a region requires a sound knowledge of the labor market situation and socioeconomic background of the region, which in turn leads ultimately to regional welfare. We find literature in the area of regional classification to be very inadequate. This study classifies Louisiana using a clustering approach in two different ways. First of all, Ward’s method has been used to classify Louisiana into labor markets based on two-way commuting flow between the parishes. Eight geographical clusters are formed …


An Alternative To Intellectual Property Theories Of Locke And Utilitarian Economics, Michael Morrissey Jan 2012

An Alternative To Intellectual Property Theories Of Locke And Utilitarian Economics, Michael Morrissey

LSU Master's Theses

In this paper, I examine two standard theories of intellectual property, voice criticisms of each theory from within their own perspectives, and offer an alternative approach to intellectual property. In the first chapter, I explicate Locke’s original property theory and provide a modern account of Lockean intellectual property as an extension of the original theory. I argue this extension is not compatible with Locke’s original thought on property rights. In the second chapter, I dissect the mainstream economic approach to intellectual property, an approach which employs utilitarianism to justify the intellectual property regime of first world, western nations. I argue …


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 …

Recently, significant increases in equine and human cases have been reported in United States. Domain III of the WNV envelope protein binds to cellular receptors, and induces a significant portion of the neutralizing antibody response against the virus. CD40 Ligand (CD40L, CD154) enhances productive interactions between T cells and APC and has been shown to function as a potential adjuvant. In this study, we constructed and expressed a fusion …


The Biomechanics Of Salt Marsh Vegetation Applied To Wave And Surge Attenuation, James Chatagnier Jan 2012

The Biomechanics Of Salt Marsh Vegetation Applied To Wave And Surge Attenuation, James Chatagnier

LSU Master's Theses

The Northern coast of the Gulf of Mexico is threatened by storm surge and waves from tropical storms. It has been long known that marsh vegetation attenuates storm surge and waves and is vital for sustaining marsh edges. However, little is known about the relationship between plant properties and the amount of storm surge and wave reduction the plants provide. In order to better understand the stiffness properties and physical dimensions of saltmarsh vegetation, which are directly related to their ability to attenuate waves and storm surge, this study has been conducted. Stiffness of salt marsh vegetation was determined through …


A Comparison Of Response-Contingent And Noncontingent Pairing In The Conditioning Of A Reinforcer, Sarah Joanne Miller Jan 2012

A Comparison Of Response-Contingent And Noncontingent Pairing In The Conditioning Of A Reinforcer, Sarah Joanne Miller

LSU Master's Theses

Two pairing procedures were compared in the conditioning of a secondary reinforcer. Pairings of a neutral stimulus and primary reinforcer were delivered either contingent upon a participant response or noncontingently (i.e., independent of a participant response). Maintenance of responding when responses resulted in the neutral stimulus alone was compared before and throughout pairing using progressive-ratio probes. Results yielded undifferentiated responding between the contingently-paired and noncontingently-paired stimuli and a stimulus never paired with reinforcement, indicating that no conditioning effect occurred. Potential factors in producing this lack of differentiation are discussed, including differences in methodology between this study and past studies.

Investigations At The Toncrey Site (16pl7): Analysis Of A Late Prehistoric Site In Extreme Southern Louisiana, Rebecca Muriel Brown Jan 2012

Investigations At The Toncrey Site (16pl7): Analysis Of A Late Prehistoric Site In Extreme Southern Louisiana, Rebecca Muriel Brown

LSU Master's Theses

The Toncrey site (16PL07), located in the coastal marsh of Plaquemines Parish, Louisiana, is a prehistoric mound site containing three earthen mounds, on the north, west, and south edges of a plaza. The layout of the mounds in cardinal directions around the plaza suggests that this component of the site dates to the Coles Creek period. On the eastern side of the site an extensive, wave-washed and re-deposited oyster (Crassostrea virginica) shell midden contains diagnostic Coles Creek, Plaquemine, and Mississippian pottery. Archaeological research at the site was conducted to confirm the cultural affiliation of the mound group and midden, and …

A Method To Improve Interest Point Detection And Its Gpu Implementation, Prabakar Karuppannan Gunashekhar Jan 2012

A Method To Improve Interest Point Detection And Its Gpu Implementation, Prabakar Karuppannan Gunashekhar

LSU Master's Theses

Interest point detection is an important low-level image processing technique with a wide range of applications. The point detectors have to be robust under affine, scale and photometric changes. There are many scale and affine invariant point detectors but they are not robust to high illumination changes. Many affine invariant interest point detectors and region descriptors, work on the points detected using scale invariant operators. Since the performance of those detectors depends on the performance of the scale invariant detectors, it is important that the scale invariant initial stage detectors should have good robustness. It is therefore important to design …


Inside And Outside, Joshua Harry George Jan 2012

Inside And Outside, Joshua Harry George

LSU Master's Theses

The boxing paintings and drawings are not about fighting as much as they are about the fighter’s existence. Many of the images show the boxer training or in an isolated environment in order to show how methodical their lives become. I see boxers as sacrificial athletes, not only because their health is at risk, but also because they must separate themselves from loved ones during training, as well as abstain from certain foods in order to maintain a certain weight. Every boxer is an underdog, in a sense. They are all at risk of losing something, whether it is their …
