Analytical Method For Detecting Pcb Derivatives At Low Levels In Surface Water Samples By Solid Phase Extraction-Liquid Chromatography/Mass Spectrometry, Shannon Recca Alford

Theses and Dissertations

Polychlorinated biphenyls (PCBs) and their metabolic derivatives are ubiquitous environmental contaminants. These compounds are of concern because of their persistence and bioaccumulation in nature. PCBs and the hydroxylated metabolites have shown endocrine-disrupting activity. A method of detection in surface water samples is important to identify and quantify the environmental contamination. In this research we have attempted to develop a method of detection. Six representative polychloromethoxybiphenyls (PCMBs) were prepared. The corresponding polychlorobiphenylols, hydroxylated PCB metabolites (OH-PCBs), were prepared from the PCMBs. A method coupling solid phase extraction with liquid chromatography, on-line electrospray ionization, and mass spectrometry (SPE-LC/ESI/MS) was developed for detection …

A feature extraction technique was used to identify aquaculture from satellite imagery. Variations in well water depth were examined in relation to the changes in aquaculture to explore its affects on the Mississippi River Valley Alluvial Aquifer (MRVA) aquifer. A soil moisture index was used to investigate preferential expansion of aquaculture onto soil moisture types. This study found that aquaculture expanded from 66,000 acres in 1984 to 142,000 acres in 2001. Total acreage of individual counties from the Feature Extraction is higher than estimates …

Effective Teaching Strategies Of Foreign Languages In Secondary Diverse Classrooms, Helen Singletary-Brinson

Theses and Dissertations

The traditional style of teaching (teachers solely in charge of the classroom) seems to be a thing of the past, due in part, to the increasing diversity of students in the classroom. How can teachers abandon their traditional roles and adapt to the trends of teaching to promote more meaningful learning for students? To respond to the above question, the researcher investigated the degree of readiness of selected foreign language teachers teaching in culturally diverse classrooms at the secondary level in central Mississippi. All participants were purposefully selected. Methods and procedures employed were limited to observations of teachers, teacher-student interaction …

An independent Two-Way ANOVA was then performed to analyze the information indicating the following …

A Study On The Ethical Implementation Of Radio Frequency Identification Technology In Retail, Aaron Ingoglia

Theses and Dissertations

Long checkout lines at the grocery store can be very frustrating. Thanks to point-of-sale technology though, those lines aren't nearly as long as they could be. Point-of-sale technologies have been developed and implemented worldwide to help reduce the amount of time it takes a consumer to pay for products at the cash register. These technologies have also aided retailers and manufacturers in achieving higher levels of efficiency. Bar codes, for example, were first developed to decrease the amount of time required to purchase an item, improve the tracking of inventory, accelerate the acquisition of important statistical data, and facilitate market …

Improving And Extending Behavioral Animation Through Machine Learning, Jonathan J. Dinerstein

Theses and Dissertations

Behavioral animation has become popular for creating virtual characters that are autonomous agents and thus self-animating. This is useful for lessening the workload of human animators, populating virtual environments with interactive agents, etc. Unfortunately, current behavioral animation techniques suffer from three key problems: (1) deliberative behavioral models (i.e., cognitive models) are slow to execute; (2) interactive virtual characters cannot adapt online due to interaction with a human user; (3) programming of behavioral models is a difficult and time-intensive process. This dissertation presents a collection of papers that seek to overcome each of these problems. Specifically, these issues are alleviated …

T-Spline Merging, Heather Ipson

Theses and Dissertations

Geometric models, such as for use in CAD/CAM or animation, are often constructed in a piece-wise fashion. Historically, these models have been made of NURBS surfaces. For various reasons it is problematic and often times mathematically impossible to combine several NURBS models into one continuous surface. The recent invention of a surface type called T-splines has made the combining of NURBS surfaces into a single continuous surface possible, but much of the mathematics has yet to be explored. This thesis explores the mathematics and algorithms necessary to merge multiple NURBS, T-spline, or T-NURCC surfaces into a single continuous surface. This …

January: Search Based On Social Insect Behavior, Peter C. Lamborn

Theses and Dissertations

January is a group of interacting stateless model checkers. Each agent functions on a processor located on a super computer or a network of workstations (NOW). The agent's search pattern is a semi-random walk based on the behavior of the grey field slug (Agriolimax reticulatus), the house fly (Musca domestica), and the black ant (Lassius niger). The agents communicate to lessen the amount of duplicate work being done. Every algorithm has a memory threshold above which they search efficiently. This threshold varies not only by model but also by algorithm. Janaury's threshold is lower than the thresholds of other algorithms …

The Effects Of Nutrient Concentrations On Macroinvertebrate Distributions In Georgia, Paula Michele Pollock Brossett

Theses and Dissertations

Nutrients are considered the second largest nonpoint source pollutant in Georgia's running water ecosystems. Nutrients can naturally occur in low amounts and are typically increased in streams as a result of industry, agriculture, silviculture, and urbanization. In large amounts, nutrients can cause many problems to occur in the stream ecosystem. Macroinvertebrates have been established as good indicators for determining the level of impairment of a stream; however, not much research has been done on how nutrients affect macroinvertebrates in a stream. Approximately 225 reference and impaired streams were sampled over a 3 - year field season, (index period from September …

Alterations In Uterine And Placental Sodium Pump Abundance May Contribute To The Onset Of Mouse Labor, Carlos Jacob Vance

Theses and Dissertations

Objective: Reductions in sodium pump (SP) abundance can give rise to increases in contractile force in uterine and vascular smooth muscle as well as an increased secretion in secretory cells, including potentially those of the placenta. To determine whether the mouse might serve as a model for human pregnancy in terms of the SP and to determine whether changes in SP abundance anticipate or follow labor, we studied pregnant mice over the final trimester of their pregnancy.

Study Design: C57Bl6 dams (n=46) were bred and studied during their pregnancy. Animals (n=4) were sacrificed at specific gestational time points. Other mice …

Phylogenetic Relationship Of Forest Spiny Pocket Mice (Genus Heteromys) Inferred From Mitochondrial And Nuclear Markers With Implications For Species Boundaries, Malinda Wallentine Gonzalez

Theses and Dissertations

I constructed a best estimate phylogeny based on congruence of multiple data sources. In recent years molecular data has been used both to construct phylogenies of taxonomic groups and to aid in the delimitation of new species. I generated and analyzed sequence data for forest spiny pocket mice (Genus Heteromys) for the mitochondrial gene cyt b (1143 bp) and two nuclear gene segments MYH2 (252 bp) and EN2 (189 bp). I used maximum parsimony and Bayesian analyses to infer relationships among species and to provide a framework for using a species delimitation method to investigate the possibility of multiple …

The Byronic Myth In Brazil: Cultural Perspectives On Lord Byron's Image In Brazilian Romanticism, Matthew Lorin Squires

Theses and Dissertations

Byron's reception in one of the nineteenth century's largest and most culturally significant post-colonial outposts, Brazil, has been virtually ignored in English studies. The implications of Lord Byron's influence in Brazil are extensive since he was overwhelmingly popular among poets but also subversive to the nationalistic aims of Brazilian Romanticism. Nearly all of the well known Brazilian Romantics were not only influenced by him, but translated him. Their notion of what it meant to be "Byronic," however, differed from ideas held in Europe. The Brazilian Byronic hero was more extreme, macabre, and sentimental, lonelier, darker, and deadlier. Byron had various …

Algal Succession And Nutrient Dynamics In Elephant Butte Reservoir, Eric J. Nielsen

Theses and Dissertations

A water quality model was created for Elephant Butte Reservoir, New Mexico to understand nutrient dynamics and algal response during a three year period. The model chosen for this study was CE-QUAL-W2 because of its proven ability to represent hydrodynamics and the ability to represent multiple algal groups. Elephant Butte has been subject to large algal blooms. This study examined the phosphorus loading into the reservoir to see if it could sustain the observed algal growth. Data showed that the amount of bioavailable phosphorus was more than enough to support large blooms. This study also was an initial attempt to …

A Uintan (Late Middle Eocene) Flora And Fauna From The Uinta Basin, Utah, Stephen Dee Sandau

Theses and Dissertations

Late Middle Eocene time marks one of the most dynamic periods of the Paleogene in the western interior of North America. Analysis of an extensive, new collection of plant, invertebrate, and vertebrae fossils from the Uinta Formation in the Uinta Basin, south of Myton, Utah, USA, provides evidence of environmental change. Paleobotanical specimens are preserved in late stage Uinta Lake sediments and coarse-grained fluvial sediments which are stratigraphically 650 to 660 m above the Green River Formation. Deposition rates estimates of 18 to 55 cm/kyr, for Uinta Lake sediments in the Uinta Basin suggest a period of 1.18 Ma to …

Vegetation Response Of A Wyoming Big Sagebrush (Artemisia Tridentata Ssp. Wyomingensis) Community To 6 Mechanical Treatments In Rich County, Utah, Daniel David Summers

Theses and Dissertations

In recent years, the importance of sagebrush to shrub-steppe ecosystems and associated plant and animal species has been recognized. The historical removal of herbaceous species by excessive and uncontrolled livestock grazing on many of our sagebrush ecosystems has resulted in a stagnant state where dense, competitive stands of sagebrush prevent herbaceous species from recovering. Most early research on sagebrush control was directed toward eradication to increase herbaceous forage for livestock production, rather than sagebrush thinning to improve shrub vigor and understory production for wildlife habitat and community diversity. Mechanical treatments have the ability to retain shrub and herbaceous components, while …

Phylogenetic History, Morphological Parallelism, And Speciation In A Complex Of Appalachian Salamanders (Genus: Desmognathus), Nathan D. Jackson

Theses and Dissertations

Understanding the mechanisms that generate shared morphologies across closely related taxa is important when identifying distinct evolutionary lineages using morphological characters. Desmognathus salamanders are an ideal group for testing hypotheses concerning the correlation between morphological similarity and genetic exchange within and among nominal species due to a pattern of high discordance between the two. Phylogeographic hypotheses are tested for populations of the D. quadramaculatus species complex throughout southern Appalachia by combining phylogenetic and population genetic methods with geographical information. Phylogenetic and phylogeographic inferences are then assessed in conjunction with morphological characteristics that have traditionally diagnosed taxonomic entities to understand the …

The Translator's (In)Visibility In Ann Patchett's Bel Canto, Amy Dawn Glauser

Theses and Dissertations

Transferring words and ideas from one language to another has always been a puzzling and difficult matter for those involved in it. For centuries, English-speakers and translators have dealt with these difficulties by enforcing, through professional codes of ethics and through publishing contracts, what Lawrence Venuti calls "the translator's invisibility," as chronicled in his book by the same name. By evaluating translation solely on the transparency and fluency of the target language translation (that is, by making a translation not seem like a translation), English translators and audiences assured that translators remained faithful to original authors' intents, or so they …

A Knowledge Matrix Modeling Of The Intelligence Cycle, Kevin J. Whaley

Theses and Dissertations

This effort models information flow through the United States Intelligence Community's Intelligence Cycle using a knowledge matrix methodology. The knowledge matrix methodology takes explicit data from multiple sources and fuses that data to measure a current level of knowledge about a target, or situation. Knowledge matrices are used to develop a measure of user-needs satisfaction. User-needs satisfaction compares requested levels of knowledge to a probability of collecting that knowledge within a designated timeframe. This effort expands the work done by Captain Carl Pawling in his March 2004 thesis, Modeling and Simulation of the Military Intelligence Process, by modeling intelligence as …
