Rapid Microwave-Assisted Acid Extraction Of Chromate Copper Arsenate (Cca)-Treated Southern Pine, Bin Yu Jan 2010

Rapid Microwave-Assisted Acid Extraction Of Chromate Copper Arsenate (Cca)-Treated Southern Pine, Bin Yu

LSU Master's Theses

Recovery of heavy metals from chromated copper arsenate (CCA) treated southern pine wood samples with three different dimension was investigated by recovery with acetic acid, oxalic acid and phosphoric acid in microwave reactor. Diluted phosphoric acid mixed with acetic acid was found to be very effective to remove copper, chromium, and arsenic from spent CCA-treated southern pine sawdust at a high temperature and in a short time. No single acid can totally recover all these three metals in one step in this method. Oxalic acid was effective in removing chromium and arsenic, and acetic acid was effective in removing copper …

Geothermal Resource Assessment Of The Gueydan Salt Dome And The Adjacent Southeast Gueydan Field, Vermilion Parish, Louisiana, Taylor Austin Gray Jan 2010

Geothermal Resource Assessment Of The Gueydan Salt Dome And The Adjacent Southeast Gueydan Field, Vermilion Parish, Louisiana, Taylor Austin Gray

LSU Master's Theses

The fluids heated by the high thermal conductivity and vertical geometry of salt domes in South Louisiana have the potential to be an economic source of geothermal energy. The Gueydan dome is a piercement salt diapir in Southwest Louisiana lying along the Vermilion and Acadia Parish border. Isotherms indicate a thermal anomaly at the crest of the dome with formation temperatures of 62 ˚C recorded at 1346 m, which is too cold for a geothermal prospect. The shallowest salt encountered is at a depth of 1475 m, and the surrounding strata are Cenozoic sand and clay deposits. Previous geothermal assessments …

Habitat Use, Movements And Spring Migration Chronology And Corridors Of Female Gadwalls That Winter Along The Louisiana Gulf Coast, Jacob M. Gray Jan 2010

Habitat Use, Movements And Spring Migration Chronology And Corridors Of Female Gadwalls That Winter Along The Louisiana Gulf Coast, Jacob M. Gray

LSU Master's Theses

The Louisiana Gulf Coast is an important wintering area for North American gadwall (Anas strepera). Conservation of winter habitat is a top priority of the Gulf Coast Joint Venture. Quantitative estimates of habitat use by wintering gadwall would help improve energetic demand models and subsequent estimates of habitat requirements. I used satellite telemetry (PTTs) to estimate winter habitat and refuge uses, spring migration chronology and corridors, as well as inter- and intra-regional winter movements of females. I used a split-plot MANOVA to evaluate the effects of individual females, female age, winter, hunt periods within winter, time of day, and all …

Evaluation Of Microfacies Controls On Hydrocarbon Seal Quality, Nchekwube Mbamalu Jan 2010

Evaluation Of Microfacies Controls On Hydrocarbon Seal Quality, Nchekwube Mbamalu

LSU Master's Theses

A microfacies based approach is proposed for the petrophysical prediction of the most effective hydrocarbon seals. Four distinct microfacies types deposited by different deep water depositional processes have been identified based on textural and mineralogical characteristics. Individual microfacies types include: 1) finely laminated, silt poor to slightly silty hemipelagic claystones; 2) faintly laminated, slightly to moderately silty distal hemiturbiditic claystones; 3) weakly laminated, moderately silty to slightly sandy intermediate hemiturbiditic mudstones; and 4) very silty and sandy proximal hemiturbiditic mudstones. Hemipelagic and distal hemiturbiditic claystones (microfacies types 1 and 2) containing well to modestly organized fabric, high total clay contents, …

Desegregation And Multiculturalism In The Portland Public Schools, Ethan Johnson, Felicia Williams Jan 2010

Desegregation And Multiculturalism In The Portland Public Schools, Ethan Johnson, Felicia Williams

Black Studies Faculty Publications and Presentations

Helen Marie Casey’s booklet Portland’s Compromise: the Colored School, 1867–1872 recounts the story of William Brown, an African-American resident of Portland, Oregon, and his role in the first and only case of official segregation of African-American children in Portland Public Schools (PPS) in 1867. After unsuccessfully trying to enroll his children in one of Portland’s only two public elementary schools, Brown appealed to the school board, including directors Josiah Failing, W.S. Ladd, and E.D. Shattuck. Again, his children were denied access. The board of directors explained their resistance to integrated schools by saying: “If we admit them [African-American children], then …

Audio Watermarking Using Transformation Techniques, Rajkiran Ravula Jan 2010

Audio Watermarking Using Transformation Techniques, Rajkiran Ravula

LSU Master's Theses

Watermarking is a technique, which is used in protecting digital information like images, videos and audio as it provides copyrights and ownership. Audio watermarking is more challenging than image watermarking due to the dynamic supremacy of hearing capacity over the visual field. This thesis attempts to solve the quantization based audio watermarking technique based on both the Discrete Cosine Transform (DCT) and Discrete Wavelet Transform (DWT). The underlying system involves the statistical characteristics of the signal. This study considers different wavelet filters and quantization techniques. A comparison is performed on diverge algorithms and audio signals to help examine the performance …

Effectiveness Of Forestry Best Management Practices In Minimizing Harvesting Impacts On Streamflow And Sediment Loading In Low-Gradient Headwaters Of The Gulf Coastal Plain, Kristopher Brown Jan 2010

Effectiveness Of Forestry Best Management Practices In Minimizing Harvesting Impacts On Streamflow And Sediment Loading In Low-Gradient Headwaters Of The Gulf Coastal Plain, Kristopher Brown

LSU Master's Theses

Few studies have examined the effectiveness of timber harvesting Best Management Practices (BMPs) in water quality protection of widely-spread, low-gradient, and highly intermittent headwaters on the Gulf Coastal Plain. Also, a spatial disparity exists between the plot-scale water quality benefits afforded by BMP implementation and the watershed-scale with which most watershed stewardship programs are managed. In this thesis research, paired-watershed and Before-After-Control-Impact (BACI) designs were utilized to quantify plot- and watershed-scale changes in streamflow, as well as baseflow and stormflow Total Suspended Sediment (TSS) concentration and yield for 27 months after clearcut harvesting with and without BMPs in a low-gradient, …

Public Perception Of Wildfire Risk And Prescribed Burning In The Wildland/Urban Interface Of The Louisiana Florida Parishes, Charlotte Ann Gerald Jan 2010

Public Perception Of Wildfire Risk And Prescribed Burning In The Wildland/Urban Interface Of The Louisiana Florida Parishes, Charlotte Ann Gerald

LSU Master's Theses

Wildfire has been suppressed in the nation’s forests for over a hundred years. The accumulation of forest fuels over time has created an urgent need to reduce fuel loads to prevent catastrophic wildfires from occurring, not only in our wildlands, but also in our Wildland/Urban Interfaces (WUI’s). The residents who live within the WUI are particularly vulnerable to extreme wildfire events. As cities become more densely populated, increasing numbers of people are moving beyond the suburbs into the WUI. A complex matrix of structures and forested land, developing communities, and impinging forests exists within the WUI. This study utilized a …

New Age Control On A Mid-Shelf Grounding Event In Eastern Basin, Ross Sea, Amy Noelle Cone Jan 2010

New Age Control On A Mid-Shelf Grounding Event In Eastern Basin, Ross Sea, Amy Noelle Cone

LSU Master's Theses

It is widely accepted that the West Antarctic Ice Sheet (WAIS) was grounded at the continental shelf edge in Eastern Ross Sea during the Last Glacial Maximum (LGM), but the precise chronology is debated. Existing post-LGM ice retreat chronologies are considered suspect because nearly all have been developed using radiocarbon dating of acid-insoluble organics (AIO). Foraminifer tests yield more accurate radiocarbon dates than AIO because unlike loose sediment, foram tests are unlikely to be contaminated by allochthonous carbon, but unfortunately forams are sparse in Antarctic marine sediment cores. Here I utilized a new 3-D multibeam survey of a mid-continental-shelf grounding …

Synthesis Of Aza-Bridged Tetraphosphine Ligands For A Dirhodium Hydroformylation Catalyst, Scott Michael Boudreaux Jan 2010

Synthesis Of Aza-Bridged Tetraphosphine Ligands For A Dirhodium Hydroformylation Catalyst, Scott Michael Boudreaux

LSU Master's Theses

A novel tetraphosphine ligand rac-et,ph-P4 (et,ph-P4 = PEt2CH2CH2(Ph)PCH2P(Ph)CH2CH2PEt2) is used for the formation of a highly active and regioselective hydroformylation catalyst. The active catalytic species, Rh2H2(ƒÝ-CO)2(et,ph-P4)]2+, is formed in situ under H2/CO pressure. This is one of the most impressive examples of homobimetallic cooperativity in homogeneous catalysis. The fragmentation of this catalyst by CO has been investigated and confirmed by in situ NMR spectroscopic studies. A new tetraphosphine ligand rac-et,ph-P4-Ph (et,ph-P4-Ph = PEt2(o-C6H4)P(Ph)CH2(Ph)P(o-C6H4)PEt2) has been synthesized to combat this fragmentation problem. However, the inability to successfully separate the meso and racemic isomers of the ligand has led to more alteration …

Designing Exhibits For Gender Equity, Toni Nicole Dancu Jan 2010

Designing Exhibits For Gender Equity, Toni Nicole Dancu

Dissertations and Theses

Gender equity has been a national and global aim for over half a century (Ceci & Williams, 2007; National Center for Education Statistics, 2003; National Science Board, 2008). While gains have been made, one area where inequity remains is spatial reasoning ability, where a large gender gap in favor of males has persisted over the years (Else-Quest, Linn, & Shibley Hyde, 2010; National Science Board, 2008; Ruble, Martin, & Berenbaum, 2006). This gender gap in spatial reasoning has had substantial societal impact on the career interests of females in areas of Science, Technology, Engineering, and Math (STEM), contributing to the …

Origin Of Pyrite Nodules At The Top Of The Nantuo Diamictites, Southern China, Changjie Liu Jan 2010

Origin Of Pyrite Nodules At The Top Of The Nantuo Diamictites, Southern China, Changjie Liu

LSU Master's Theses

Pyrite nodules up to 20 cm in diameter are found at the top of the Marinoan (~635 Ma) Nantuo glacial diamictite as well as in the cap dolostones and shale/siltstones in the lower Doushantuo Formation in eastern Guizhou, southern China. Earlier studies on the occurrence and stable sulfur and triple oxygen isotope composition of barite in the cap dolostones concluded that seawater sulfate concentrations in shallow oceans in the South China Block were low during the deposition of the cap dolostones. Therefore, the occurrence of pyrite nodules suggests two scenarios: 1) Formation before the precipitation of the cap dolostone, when …

Physical And Microbial Responses Of Dredged Sediment To Two-Soil-Stabilizing Amendments, Xanthan Gum And Guar Gum, For Use In Coastal Wetland Restoration, Lauren Land Jan 2010

Physical And Microbial Responses Of Dredged Sediment To Two-Soil-Stabilizing Amendments, Xanthan Gum And Guar Gum, For Use In Coastal Wetland Restoration, Lauren Land

LSU Master's Theses

In wetland sediments, organic matter provides a substrate for microbial activity. During metabolism, microbes release extracellular polymeric substances, which accumulate to bind soil particles. A similar concept can be implemented on a large scale to reduce wetland loss in Louisiana. Hypothetically, hydraulically dredged sediment can be amended with polymer and deposited on subsiding marshes as a restoration method where the polymer increases sediment stabilization until plants become established. This lab study focused on investigating the influence of natural polymer additions on particle aggregation to increase sediment stability and the effects on microbial activity. Sediments from three sites (i.e. freshwater, intermediate, …

Caged Morpholino Oligonucleotide For Control Of Gene Expression In Zebrafish, Chad Michael Jarreau Jan 2010

Caged Morpholino Oligonucleotide For Control Of Gene Expression In Zebrafish, Chad Michael Jarreau

LSU Master's Theses

To control gene expression in vivo with spatial and temporal precision remains a significant hurdle in laboratory studies of development as well as clinical genetic therapies. Here we demonstrate such control over gene expression by use of photochemistry to reversibly inactivate the hybridization of a nucleic acid analog used for specific protein knockdown. A morpholino oligonucleotide, commonly used for knockdown of protein expression in developmental studies, was “caged” using carbodiimide conjugate chemistry which yielded photocleavable adducts that can be removed with light exposure. Photochemical inactivation approaches to produce caged molecules have been used to control the spatiotemporal activity of biomolecules …

Geothermal Energy Potential Of South Bossier Parish, Louisiana, John Adam D'Aquin Jan 2010

Geothermal Energy Potential Of South Bossier Parish, Louisiana, John Adam D'Aquin

LSU Master's Theses

Northwestern Louisiana sits atop a geothermal anomaly that stretches across Eastern Texas and into Southern Arkansas. Geothermal gradients are observed in this area that are greater than the Gulf Coast average of 22-26oC/km. South Bossier Parish, in particular, could be an ideal location for economic production of electricity by conventional geothermal or enhanced geothermal projects due to ideal geothermal production temperatures of 120-180oC at a relatively shallow depth of approximately 3-5 km. A localized geothermal of 35oC/km gradient was determined using bottom-hole temperatures (BHTs) from 147 wells. At approximately 3.2 km depth, temperatures of approximately 130oC within the geopressured sands …

The Influences Of Microbial Diversity On Carbonate Geochemistry Across A Transition From Fresh To Saline Water In The Edwards Aquifer, Texas, Cassie Jo Gray Jan 2010

The Influences Of Microbial Diversity On Carbonate Geochemistry Across A Transition From Fresh To Saline Water In The Edwards Aquifer, Texas, Cassie Jo Gray

LSU Master's Theses

Microbially-mediated karstification through the production of metabolic byproducts has been well-documented in cave environments, but less is known about deep karstic settings. This research aimed to distinguish between microbial and geochemical influences on carbonate dissolution in the Edwards Aquifer, a prolific karst aquifer in central Texas, specifically from a transect of six wells across a transition from fresh to saline water in New Braunfels. For the first time, a portion of the aquifer’s bacterial diversity was examined from molecular 16S rRNA gene sequence analyses, which revealed that Alphaproteobacteria, Gammaproteobacteria, and Betaproteobacteria dominated the aquifer, with rare Bacteroidetes, Nitrospirae, and Firmicutes …

A New Technique For Firn Grain-Size Measurement Using Sem Image Analysis, N.E. Spaulding, D.A. Meese, I. Baker, P.A. Mayewski Jan 2010

A New Technique For Firn Grain-Size Measurement Using Sem Image Analysis, N.E. Spaulding, D.A. Meese, I. Baker, P.A. Mayewski

Dartmouth Scholarship

Firn microstructure is accurately characterized using images obtained from scanning electron microscopy (SEM). Visibly etched grain boundaries within images are used to create a skeleton outline of the microstructure. A pixel-counting utility is applied to the outline to determine grain area. Firn grain sizes calculated using the technique described here are compared to those calculated using the techniques of Gow (1969) and Gay and Weiss (1999) on samples of the same material, and are found to be substantially smaller. The differences in grain size between the techniques are attributed to sampling deficiencies (e.g. the inclusion of pore filler in the …

Climate Change And Freshwater Resources In Oregon, Heejun Chang, Julie Jones Jan 2010

Climate Change And Freshwater Resources In Oregon, Heejun Chang, Julie Jones

Institute for Sustainable Solutions Publications and Presentations

Climate change will affect various sectors of water resources in Oregon in the 21st century. The observed trends in streamflow show significant declines in September flow and, although not significant, increases in March flow in many transient rain-snow basins. These streamflow trends are associated with rising temperature and coincident declines in snowpack in spring in the latter half of the 20th century. While there are no distinct trends in high precipitation events, such events are associated with climate variability such as ENSO and PDO. Effects of ENSO and PDO are more pronounced at the beginning and end of the wet …

School Choice At The Crossroads Of Race, Class, And Accountability: An Analysis Of The Effects Of Voluntary School Choice On Elementary Schools In A Large District In The Southeastern United States, Teresa Craig Evans

USF Tampa Graduate Theses and Dissertations

In recent years, the responsibility for the desegregation of American public schools has transitioned from federal court mandates to school board programs and policies. There is widespread belief that this has resulted in the resegregation of schools across the country. One popular policy that is purported to provide the opportunity for voluntary integration, along with accountability for academic quality, is school choice. The purpose of this study was to consider the implications of such a policy in one large school district. There is an extensive body of research exploring who participates in school choice, how they make their choices, and …

Symbolic Structures As Systems: On The Near Isomorphism Of Two Religious Symbols, Martin Zwick Jan 2010

Symbolic Structures As Systems: On The Near Isomorphism Of Two Religious Symbols, Martin Zwick

Complex Systems Faculty Publications and Presentations

Many symbolic structures used in religious and philosophical traditions are composed of “elements” and relations between elements. Similarities between such structures can be described using the systems theoretic idea of “isomorphism.” This paper demonstrates the existence of a near isomorphism between two symbolic structures: the Diagram of the Supreme Pole of Song Neo-Confucianism and the Kabbalistic Tree of medieval Jewish mysticism. The similarities of these two symbols in form and meaning are remarkable in the light of the many differences that exist between Chinese and Judaic thought. Intercultural influence might account for these similarities, but there is no historical evidence …
