Multifunctional Ligands For Supramolecular Chemistry, James Kakoullis
LSU Master's Theses
Metal-organic frameworks (MOFs) are the primary focus of the Maverick research group, almost exclusively with the acac moeity. Before such MOFs can be attempted, multifunctional ligands of the appropriate geometry for the desired MOFs first must be synthesized. In this thesis, the synthesis and characterization of two new β-diketone ligands, specifically, Re(CO)3Cl(PyacH)2, 2.2, Pphac3H3, 1.23, and its oxide 3.6, are described. Also in this thesis, attempts to synthesize other new MOFs will be discussed. The MOF for which Re(CO)3Cl(PyacH)2, 2.2 was designed was Re(CO)3ClCu(pyac)2] …

Heavy Mineral Analysis Of The Pecan Island Complex, Louisiana Chenier Plain, Southwest Louisiana, Cherie' Jenae Lee
Heavy Mineral Analysis Of The Pecan Island Complex, Louisiana Chenier Plain, Southwest Louisiana, Cherie' Jenae Lee
LSU Master's Theses
This study reports the results of a heavy mineral analysis of samples from Pecan Island and associated ridges on the Louisiana Chenier Plain. The goal of the study is to provide additional insight on the origins of the sand comprising the ridges. Chenier plains are multi-membered, progradational ridge-interridge mudflat sequences (Augustinus, 1989). The various suggested sources of the sand grains include: the Mississippi River, especially the Teche sub-delta; the Mermentau and Calcasieu Rivers; and the reworking of older mudflat and chenier ridges. Several liters of sand were collected from a depth of 0.5 to 2.0 meters at locations near the …
Quantifying The Edge Effects Associated With Predator Removal Blocks On The Nesting Success Of Upland Ducks In North Dakota, Margaret Jean Kuhn
Quantifying The Edge Effects Associated With Predator Removal Blocks On The Nesting Success Of Upland Ducks In North Dakota, Margaret Jean Kuhn
LSU Master's Theses
Much evidence suggests that nest success is one of the key drivers of duck production. Accordingly, for the past thirty years, waterfowl managers have focused their efforts on increasing nest success. One way to increase nest success is through predator trapping. Previous studies have shown that predator trapping increases nest success on different sized trapped blocks. This study attempted to answer the question: does trapping affect nest success on areas directly adjacent to trapped block boundaries? I hypothesized that predator abundance outside trapped blocks would be reduced. I predicted that nest success would decline with distance from the boundary while …
Evaluation Of Compliance With The Long Term 1 Enhanced Surface Water Treatment Rule, Racquel Rena Douglas
Evaluation Of Compliance With The Long Term 1 Enhanced Surface Water Treatment Rule, Racquel Rena Douglas
LSU Master's Theses
Cryptosporidium is a common protozoan parasite that causes cryptosporidiosis, a severe gastrointestinal disease. Currently, there is no antibiotic available to treat the disease. Cryptosporidium has been responsible for several waterborne disease outbreaks in the United States. The largest cryptosporidiosis outbreak in United States history occurred in Milwaukee, Wisconsin in spring 1993. The vulnerability of the United State drinking water supply to waterborne disease outbreak is still prevalent nearly 15 years after the Milwaukee outbreak. In order to effectively control Cryptosporidium, the EPA has strengthened the regulations on turbidity control for filtration performance by implementing the Long Term 1 Enhanced Surface …
Effects Of Predator Activity On The Nesting Of American Black Ducks And Other Birds On Barrier Islands In The Mid-Atlantic Coast, Brian Joseph Arquilla
Effects Of Predator Activity On The Nesting Of American Black Ducks And Other Birds On Barrier Islands In The Mid-Atlantic Coast, Brian Joseph Arquilla
LSU Master's Theses
Landscape change throughout North America has resulted in heightened nest predator population and declining avian productivity. Essential to establishing effective management design is an understanding of differential predation pressure among avian groups as group specific responses to predation impact may exist. The objective of this study was to examine the efficacy of predator trapping on the nest success and density of ground nesting avifauna in 2004-2005 in the Virginia Coast Reserve, specifically dabbling ducks, Canada Goose and Willet. Second, we determine the impact of predation on ground nesting birds by relating indices of predator abundance to nest density and nest …

Protocol Development For Pro-Active Emergency Responses By Veterinary Clinics And Hospitals, Laura Marie Basirico
LSU Master's Theses
The Gulf Coast hurricanes of 2005 necessitated the development of a guidance document concerning emergency preparedness and response for veterinary clinics and hospitals. The aftermaths of the largest natural disasters in United States' history, namely Hurricanes Katrina and Rita, brought to light the need for a protocol designed specifically for veterinarians and veterinary practitioners. Disaster management information was synthesized and modified to be subject-specific for the veterinary community. This synthesis resulted in the creation of the Veterinary Emergency Preparedness and Response (VEPR) manual and website. Two types of data were collected to develop the emergency protocol; interviews with veterinarians and …

Early Flotant Establishment And Growth Dynamics In A Nutrient Amended Wetland In The Lower Mississippi River Delta, Caleb W. Izdepski
LSU Master's Theses
Nutrient dynamics and seasonal marsh growth were examined in a newly formed Panicum virgatum floating marsh at Thibodaux LA. The floating marsh formed in a cleared area of forested wetland receiving secondarily treated effluent. Net Areal Primary Productivity (NAPP), total belowground biomass, NO3, and δ15N ratios varied significantly (P <0.05) along a 75m marsh transect while mean δ13C varied between plant species. The upland end of the transect had the highest NAPP (3876 g m-2y-1), total belowground biomass (4079.0 ± 298.5 g m-2), and mean NO3 (5.4 ± 2.9 mg l-1). The mean floating-marsh …
A Directional Algorithm For An Electronically-Collimated Radiation Detector (Ecrd), Adam Lackie
A Directional Algorithm For An Electronically-Collimated Radiation Detector (Ecrd), Adam Lackie
LSU Master's Theses
An electronically-collimated radiation detector (ECRD) is being developed to be used for locating radiation sources, e.g. for intraoperative localization of sentinel lymph nodes, or for public safety applications. The design emphasizes a compact, portable detector with a wide field of view. Typical probes provide either high sensitivity but no directional information when uncollimated, or directional information but poor detection efficiency when collimated. The ECRD design provides high sensitivity to the presence of radiation because it lacks physical collimation, and simultaneously provides directional information using electronic collimation. Intended to be a hand-held device, the ECRD front end comprises an array of …

Evaluation Of Harvesting Disturbance And Establishment Practices On Early Height Growth Of Loblolly Pine (Pinus Taeda L.), Shanna Marie Mccarty
LSU Master's Theses
Land for forest plantations is declining while demand for forest products is increasing, creating concern over sustainable forest management. Maintenance of site productivity is fundamental to forest sustainability, and an assessment of cumulative height growth is a useful index of productivity. Loblolly pine height data were used from four research plantations installed by the project Cooperative Research in Sustainable Silviculture and Soil Productivity from Texas to Georgia. The sites vary in soil characteristics, management history, nutrient status at time of planting, and age (from 4 to 9 years). Each site is a randomized complete block design with a factorial treatment …
Ecosystem Effects Of Expanding Populations Of Avicennia Germinans In A Southeastern Louisiana Spartina Alterniflora Saltmarsh, Carey Lynn Perry
Ecosystem Effects Of Expanding Populations Of Avicennia Germinans In A Southeastern Louisiana Spartina Alterniflora Saltmarsh, Carey Lynn Perry
LSU Master's Theses
Although the Earth may be in the early stages of the projected trends of global warming, several ecological responses to recent warming are already evident. The timing of seasonal activities of plants and animals has begun to shift, and the advancement of species poleward is occurring in several regions of the world. One unique distributional shift is the movement of Avicennia germinans (black mangrove) northward into temperate salt marshes dominated by the marsh grass, Spartina alterniflora. In Louisiana, black mangroves were historically restricted to the southernmost barrier islands and beaches; however, in recent years a noticeable expansion of Avicennia northward …

The total phenol content of the extracts was determined by the Folin-Ciocalteu method and expressed as Gallic Acid Equivalent …
Fluid Flow In The Central North Slope Foreland Basin, Alaska, Anna Marie Bélanger
Fluid Flow In The Central North Slope Foreland Basin, Alaska, Anna Marie Bélanger
LSU Master's Theses
Previous studies of the areal variations in heat flow and spatial variations in formation water salinity and hydraulic head are consistent with the existence of a currently active, topographically-driven regional fluid flow regime in the National Petroleum Reserve Alaska (NPRA) portion of the western North Slope foreland basin. This conclusion is also supported by the results of numerical modeling of fluid flow and heat transport in the area. This work has now been extended to the east. The results of this study demonstrate that the Permian though Cenozoic age sediments of the central North Slope foreland basin have been significantly …

Rna:Dna As An Indicator Of Nutritional Condition And Growth In Larval Naked Goby, Gobiosoma Bosc, Michelle C. Satterwhite
LSU Master's Theses
Developing organism-based metrics for assessing habitat quality is an important tool in conservation and restoration of aquatic habitats. The use of the RNA:DNA ratio as an early indicator of habitat effects on growth of nekton species has been suggested, but requires species-specific laboratory assessment prior to field application. We used food availability in laboratory treatments to simulate differences in habitat quality. Wild Gobiosoma bosc eggs were collected using nest-traps constructed of PVC pipe. Eggs from several different nests collected in the field were hatched in the lab, yielding larvae that were randomly assigned to three feeding treatments in two replicate …

Spatial Ecology, Habitat Selection, And Survival Of Wild Turkey Gobblers In A Managed Bottomland Hardwood Forest, Blake Anthony Grisham
LSU Master's Theses
Wild turkey (Meleagris gallopavo) males were captured and radio-tagged in a bottomland hardwood forest of south-central Louisiana. Turkeys were monitored year round from fixed telemetry stations on Sherburne Wildlife Management Area, Atchafalaya National Wildlife Refuge, and Bayou des Ourses to observe seasonal patterns of space use, habitat selection and survival from 2005-07. The largest seasonal home range was in fall/winter (966.41 ha; Oct 1-Feb 28). Spring home range (767.77 ha; Mar 1- May 31) size was lower than reported in previous studies and was a function of female availability. Season and age interacted to influence core area size (F5/63 …
Habitat Use, Movements, And Survival Of Radio-Marked Female Mallards In The Lower Mississippi Alluvial Valley, Bruce Edward Davis
Habitat Use, Movements, And Survival Of Radio-Marked Female Mallards In The Lower Mississippi Alluvial Valley, Bruce Edward Davis
LSU Master's Theses
Mallard (Anas platyrhynhcos) populations in the Lower Mississippi Alluvial Valley (LMAV) historically averaged 1.6 million and represented the largest concentrations of wintering mallards in North America. Effective management of this wintering population requires current information on use of habitats, movements, and survival of female mallards. I used radio-telemetry techniques to assess these parameters during winters 2004-2005 and 2005-2006. Radio-marked female mallards used forested wetland habitats extensively during diurnal and nocturnal sampling periods. Proportional use of habitats varied inconsistently among time periods defined by hunting seasons and winters. Proportional use of forested wetlands ranged from 0.464 to 0.816 and from 0.280 …

Biogeomorphic Evaluation Of Caminada-Moreau Maritime Beach Ridges With Respect To Future Restoration Initiatives, Hannon Didier
Biogeomorphic Evaluation Of Caminada-Moreau Maritime Beach Ridges With Respect To Future Restoration Initiatives, Hannon Didier
LSU Master's Theses
Restoration efforts within the coastal zone of southern Louisiana have assumed greater importance in the wake of recent storms and ever increasing sea level rise. A poorly studied geomorphic structure known as the Caminada-Moreau maritime beach ridge complex exists along the southeastern Louisiana coastline between Grand Isle and the Port of Fourchon. Active subsidence in the area has reduced the overall elevation of these structures, decreasing the live cover of its most noticeable feature, stands of Quercus virginiana (live oak), along the ridge spines. Elevation data was gathered along and across four randomly selected ridges in the study area with …

Global weather changes have become a matter of grave concern in hurricane prone areas as intensities of hurricanes are observed to be increasing every year, necessitating improved monitoring capabilities. NASA’s QuikSCAT satellite sensor has provided significant support in analyzing and forecasting winds for the past 8 years. In this study, the performance of QuikSCAT products, including JPL’s latest L2B 12.5km swath winds, was evaluated against buoy-measured winds in the Gulf of Mexico. The long-term study period was 1/2005 – 2/2007. The Coupled Ocean/Atmospheric Mesoscale Prediction System (COAMPS) was also assessed. The regression analyses showed very good results for QuikSCAT products, …
Spatial Ecology Of Gray Foxes On A Longleaf Pine Forest And The Surrounding Landscape In Southwestern Georgia, Danielle Lolene Temple
Spatial Ecology Of Gray Foxes On A Longleaf Pine Forest And The Surrounding Landscape In Southwestern Georgia, Danielle Lolene Temple
LSU Master's Theses
In the southeastern United States, industrial agriculture dominates the landscape, and much of the native land cover is in decline. Longleaf pine forests were once a dominant ecosystem in this region, but have largely disappeared. However, little research has been conducted on how this loss affects wildlife, especially mammalian predators. With increasing restoration efforts for longleaf pine it is important to assess the impact on species that inhabit those landscapes. Gray foxes (Urocyon cinereoargenteus) are native to the Southeast, but are adaptable to a wide range of habitats. Therefore, during 2002-2006 I studied a population of gray foxes on land …
Empirical Modeling Of Late Quaternary Sediment Supply To The Gulf Of Mexico Shelf Margin In A Cool Lowstand World, Jill Hattier Womack
Empirical Modeling Of Late Quaternary Sediment Supply To The Gulf Of Mexico Shelf Margin In A Cool Lowstand World, Jill Hattier Womack
LSU Master's Theses
During the last glacial period, river systems responded to the lowering of sea level by incising valleys, extending across the continental shelf, and depositing deltas on the shelf margin and upper slope of surrounding basins. These deltas represent important repositories for sediment delivered to the coastal ocean and provide partial records of sediment discharged from continental landmasses. Over relatively short time scales, like that of the last glacial-interglacial cycle, hinterland drainage areas, relief and lithology can be considered constants while the primary variable of significance is climate change (Syvitski and Milliman, 2007). It is reasonable to assume, therefore, that supply …
Carbonated Sections From Komatiite Flow- Top Alteration Zones In The Barberton Greenstone Belt: Implications For Near-Surface Archean Environments, Judith E. F. Stoute
Carbonated Sections From Komatiite Flow- Top Alteration Zones In The Barberton Greenstone Belt: Implications For Near-Surface Archean Environments, Judith E. F. Stoute
LSU Master's Theses
Over a dozen komatiitic flows in the 3.2-3.5 Ga Barberton Greenstone Belt are topped with unique green silica- and carbonate-rich rocks, which likely formed from interaction of the cooling lava flow with seawater shortly after deposition. This study focuses on an alteration zone in the Mendon Formation. Two styles of alteration are observed in this alteration zone: silicification and carbonation. The goal of this study is to characterize the carbonates in the alteration zone, constrain the timing of alteration, test whether the alteration zones are due to interaction with seawater after deposition, and estimate the elemental fluxes between the rock …
An Architecture For Embedded System Communication, Chakradhar Medavarapu
An Architecture For Embedded System Communication, Chakradhar Medavarapu
LSU Master's Theses
Time is a major constraint in the development of most embedded systems. In many cases, the development of embedded software is directly dependent on the development of the embedded systems. This calls for a development framework that enables embedded software and hardware to be developed in parallel. In an attempt to solve the problem, a concept prototype hardware-in-the-loop (HIL) simulation methodology has been proposed and implemented at the Ohio State University for the TMS320LF2407A DSP board. We build on top of that HIL system by rewriting the low level device drivers that allow data and control information to be set …
A Study Of Subsurface Vapor Intrusion From Exploration & Production Waste, Daniel Dawson Wascom
A Study Of Subsurface Vapor Intrusion From Exploration & Production Waste, Daniel Dawson Wascom
LSU Master's Theses
Expanding city growth is causing the inhabitants of Louisiana to move further into rural areas. Abandoned oil and gas production sites are being used for residential and light commercial purposes. This thesis will attempt to determine if known benzene levels in Exploration and Production (E&P) waste will be harmful to human health via subsurface vapor intrusion into the newly developed residential and light commercial structures. Louisiana does not currently regulate benzene during the closure of pits that contained E&P waste. Current pit closure techniques warrant testing for benzene Based on current Louisiana legislation, benzene contamination of groundwater is currently the …
Survival, Habitat Use, And Movements Of Female Mallards Wintering In Southwestern Louisiana, Paul Thomas Link
Survival, Habitat Use, And Movements Of Female Mallards Wintering In Southwestern Louisiana, Paul Thomas Link
LSU Master's Theses
Little information is available concerning survival, habitat use, and movements of mallards (Anas platyrhychos) wintering on the Gulf Coast Chenier Plain (GCCP). Quantitative data on these parameters would be useful in making effective management decisions by GCCP waterfowl managers. Accordingly, I radio-marked 135 female mallards during winters 2004-2005 and 2005-2006 in southwestern Louisiana. My estimated survival rate for both winters combined was 0.68 ± 0.06 and did not differ by female age. Hazard ratios indicated that radio-marked females were 21-24 times more likely to die during hunted time periods than during non-hunted time periods. Estimated hunting and non-hunting mortality rates …
