Magnesium And Acidified Ethanol Based Treatment Systems For The Extraction And Dechlorination Of Polychlorinated Biphenyls From Contaminated Oils, Paints, And Soils, Simone Novaes-Card Jan 2013

Magnesium And Acidified Ethanol Based Treatment Systems For The Extraction And Dechlorination Of Polychlorinated Biphenyls From Contaminated Oils, Paints, And Soils, Simone Novaes-Card

Electronic Theses and Dissertations

Polychlorinated biphenyls (PCBs) are a class of environmentally persistent halogenated organic compounds that were once used as stabilizers to improve the properties of a variety of materials such as lubricants, heat transfer fluids, paints, and caulking materials. PCBs are also capable of migration through processes such as spillage into soils, leaching into groundwater, and volatilization into the atmosphere. Although banned in 1979 over health concerns, PCBs persist in these materials to this day because they are resistant to biotic degradation and natural weathering processes. The wide variety of contaminated materials means that many existing treatment options cannot be used across …

On The Capillary Electrophoresis Of Monohydroxy Metabolites Of Polycyclic Aromatic Hydrocarbons And Its Application To The Analysis Of Biological Matrices, Gaston Knobel

Electronic Theses and Dissertations

Polycyclic aromatic hydrocarbons (PAH) are a class of environmental pollutants consisting of a minimum of two fused aromatics rings originating from the incomplete combustion of organic matter and/or anthropogenic sources. Numerous possible anthropogenic and natural sources make the presence of PAH ubiquitous in the environment. The carcinogenic nature of some PAH and their ubiquitous presence makes their chemical analysis a topic of environmental and toxicological importance. Although environmental monitoring of PAH is an important step to prevent exposure to contaminated sites, it provides little information on the actual uptake and subsequent risks. Parent PAH are relatively inert and need metabolic …

A Delphi Study To Construct A Script Concordance Test For Spiritual And Religious Competence In Counseling, Christopher Christmas

Electronic Theses and Dissertations

The need to address spiritual and religious issues is well established in the counseling literature and in accreditation standards, however, many graduates counseling students do not feel prepared to address these issues. In the United States, the vast majority of clients consider themselves to be spiritual or religious, so counselors who lack competence in addressing spiritual and religious issues in counseling are likely to offer ineffective or perhaps unethical care to clients. Counselor educators must improve education and assessment in this critical specialty area of counseling. Of primary concern is a student’s ability to demonstrate spiritual competence in counseling. The …

Target Validation For Neurofibromatosis Type 2 Therapeutics., Alejandra Guinart Jan 2013

Target Validation For Neurofibromatosis Type 2 Therapeutics., Alejandra Guinart

Electronic Theses and Dissertations

Neurofibromatosis type 2 (NF2) is a benign tumor disease of the nervous system. Development of bilateral vestibular schwannomas is characteristic of NF2; however patients frequently present schwannomas on other nerves, as well as meningiomas and ependymomas. Currently, there are no drug therapies for NF2. There is an urgent need for development of NF2 therapeutics and this dissertation presents two independent potential therapeutic targets. The disease is caused by mutations in the NF2 gene that encodes a tumor suppressor called merlin. Loss of merlin function is associated with increased activity of Rac and p21-activated kinases (PAK) and deregulation of cytoskeletal organization. …

Characterization Of Innate Immunity In The Female Reproductive Tract For The Prevention Of Hiv Acquisition, Colleen Eade Jan 2013

Characterization Of Innate Immunity In The Female Reproductive Tract For The Prevention Of Hiv Acquisition, Colleen Eade

Electronic Theses and Dissertations

Human immunodeficiency virus (HIV) infects 30 million people worldwide. In sub-Saharan Africa, the region most affected by HIV, women comprise 60% of the infected population. Heterosexual transmission is a major mode of viral acquisition, mandating further research of the process and prevention of HIV acquisition via the female reproductive tract (FRT). The FRT is a dynamic environment, protected by host immune mechanisms and commensal microbes. The disruption of either of these elements can increase susceptibility to HIV. Accordingly, one common risk factor for HIV acquisition is the microbial shift condition known as bacterial vaginosis (BV), which is characterized by the …

Molecular Regulators Of Post-Golgi Vldl Transport Vesicle (Pg-Vtv) Biogenesis, Aladdin Riad Jan 2013

Molecular Regulators Of Post-Golgi Vldl Transport Vesicle (Pg-Vtv) Biogenesis, Aladdin Riad

Electronic Theses and Dissertations

Amongst its numerous functions, the liver is responsible for the synthesis and secretion of very low-density lipoprotein (VLDL). VLDL particles play the important role of facilitating the transport of lipids within the aqueous environment of the plasma; yet high plasma concentrations of these particles result in the pathogenesis of atherosclerosis, while low VLDL secretion from the liver results in hepatic steatosis. VLDL synthesis in the hepatocyte is completed in the Golgi apparatus, which serves as the final site of VLDL maturation prior to its secretion to the bloodstream. The mechanism by which VLDL’s targeted transport to the plasma membrane is …

Role Of Host Immune Response And Bacterial Autolysin Atl In Human Nasal Colonization By Staphylococcus Aureus, Vanathy Paramanandam Jan 2013

Role Of Host Immune Response And Bacterial Autolysin Atl In Human Nasal Colonization By Staphylococcus Aureus, Vanathy Paramanandam

Electronic Theses and Dissertations

Staphylococcus aureus (SA) is a major human pathogen that colonizes the anterior nares in 30% of the human population. Though nasal carriage of SA is a known risk factor for the subsequent spread of SA infections, the dynamics of SA nasal colonization is poorly understood. Our research focuses on understanding the host and bacterial factors that might contribute to the human nasal colonization by SA. In an attempt to elucidate the host response to SA, we performed an autologous human in vivo nasal colonization study, which showed decreased survival rates of SA in hosts who elicited a robust immune response. …

Enhanced Detection Of Host Response Antibodies To Borrelia Burgdorferi Using Immuno-Pcr, Micah D. Halpern, Sunny Jain, Mollie W. Jewett

Faculty Bibliography 2010s

Lyme disease is the fastest-growing zoonotic disease in North America. Current methods for detection of Borrelia burgdorferi infection are challenged by analysis subjectivity and standardization of antigen source. In the present study, we developed an immuno-PCR (iPCR)-based approach employing recombinant in vivo-expressed B. burgdorferi antigens for objective detection of a host immune response to B. burgdorferi infection. iPCR is a liquid-phase protein detection method that combines the sensitivity of PCR with the specificity and versatility of immunoassay-based protocols. Use of magnetic beads coated with intact spirochetes provided effective antigen presentation and allowed detection of host-generated antibodies in experimentally infected mice …

A Conserved Hydrolase Responsible For The Cleavage Of Aminoacylphosphatidylglycerol In The Membrane Of Enterococcus Faecium, Angela M. Smith, Jesse S. Harrison, Kevin M. Sprague, Hervé Roy Jan 2013

A Conserved Hydrolase Responsible For The Cleavage Of Aminoacylphosphatidylglycerol In The Membrane Of Enterococcus Faecium, Angela M. Smith, Jesse S. Harrison, Kevin M. Sprague, Hervé Roy

Faculty Bibliography 2010s

Aminoacylphosphatidylglycerol synthases (aaPGSs) are enzymes that transfer amino acids from aminoacyl-tRNAs (aa-tRNAs) to phosphatidylglycerol (PG) to form aa-PG in the cytoplasmic membrane of bacteria. aa-PGs provide bacteria with resistance to a range of antimicrobial compounds and stress conditions. Enterococcus faecium encodes a triple-specific aaPGS (RakPGS) that utilizes arginine, alanine, and lysine as substrates. Here we identify a novel hydrolase (AhyD), encoded immediately adjacent to rakPGS in E. faecium, which is responsible for the hydrolysis of aa-PG. The genetic synteny of aaPGS and ahyD is conserved in > 60 different bacterial species. Deletion of ahyD in E. faecium resulted in increased formation …

Biochemical Characterization Of The Nifb Enzyme And Nifb-Cofactor, Jirair Gevorkyan Jan 2013

Biochemical Characterization Of The Nifb Enzyme And Nifb-Cofactor, Jirair Gevorkyan

Electronic Theses and Dissertations

The Mo-nitrogenase complex is composed of two components, Fe-protein and MoFe-protein. This complex is able to catalyze the reduction of N2 through the MgATP dependent transfer of electrons from the Fe-protein Fe4S4 cluster to the MoFe-protein P-cluster and, subsequently, to the iron-molybdenum cofactor (FeMoco). FeMo-co is a Fe7S9MoC-(R)-homocitrate cluster and has two biosynthetic precursors, NifB-co and L-cluster, of unknown structure and composition. The biosynthesis of FeMo-co is an enigmatic process that minimally requires NifB, NifEN, Fe-protein, MoO4 2- , (R)-homocitrate and S-adenolsylmethionine. A means to isolate the NifB enzyme for characterization has been developed through use of a GST-fusion tag. …

Becoming A Food Citizen, Nicole Hornung Jan 2013

Becoming A Food Citizen, Nicole Hornung

Electronic Theses and Dissertations

Environmental citizenship is positioned as a platform where the rights of social and environmental justice converge with civic engagement and responsibility. As industrialized economies continue to exhaust the limits of finite natural resources and exacerbate conditions of global climate change, scholars have questioned if environmental citizenship models offer a method for deepening obligations to a sustainable movement. In the material culture enjoyed by Western civilizations, existing research supports that an individual’s purchases are seen as an indicator of their values and identities. Consequently the commitment to responsible buying behavior or sustainable consumption is in a sense an expression of eco-citizenship. …

Tracking Violence: Using Neighborhood-Level Characteristics In The Analysis Of Domestic Violence In Chicago And The State Of Illinois, Rachel Morgan Jan 2013

Tracking Violence: Using Neighborhood-Level Characteristics In The Analysis Of Domestic Violence In Chicago And The State Of Illinois, Rachel Morgan

Electronic Theses and Dissertations

Social disorganization theory proposes that neighborhood characteristics, such as residential instability, racial and ethnic heterogeneity, concentrated disadvantage, and immigrant concentration contribute to an increase in crime rates. Informal social controls act as a mediator between these neighborhood characteristics and crime and delinquency. Informal social controls are regulated by members of a community and in a disorganized community these controls are not present, therefore, crime and delinquency flourish (Sampson, 2012). Researchers have focused on these measures of social disorganization and the ability to explain a variety of crimes, specifically public crimes. Recently, researchers have focused their attention to characteristics of socially …

Chemophysical Characteristics And Application Of Biosorption Activated Media (Bam) For Copper And Nutrient Removal In Stormwater Management, Jamie Jones Jan 2013

Chemophysical Characteristics And Application Of Biosorption Activated Media (Bam) For Copper And Nutrient Removal In Stormwater Management, Jamie Jones

Electronic Theses and Dissertations

For high groundwater table areas, stormwater wet detention ponds are utilized as the preferred stormwater management throughout the state of Florida. Previous research has found that accumulations of nutrients, algae, heavy metals, pesticides, chlorophyll a, fecal coliform bacteria and low concentrations of dissolved oxygen (DO) are common characteristics of stormwater wet detention ponds. Although these pollutant levels are not regulated within the ponds, states are required to compute the pollutant load reductions through total maximum daily load (TMDL) programs to meet the water quality requirements addressed by the Clean Water Act (CWA). In this study, field sampling data of stormwater …

Integrated Data Fusion And Mining (Idfm) Technique For Monitoring Water Quality In Large And Small Lakes, Benjamin Vannah Jan 2013

Integrated Data Fusion And Mining (Idfm) Technique For Monitoring Water Quality In Large And Small Lakes, Benjamin Vannah

Electronic Theses and Dissertations

Monitoring water quality on a near-real-time basis to address water resources management and public health concerns in coupled natural systems and the built environment is by no means an easy task. Furthermore, this emerging societal challenge will continue to grow, due to the ever-increasing anthropogenic impacts upon surface waters. For example, urban growth and agricultural operations have led to an influx of nutrients into surface waters stimulating harmful algal bloom formation, and stormwater runoff from urban areas contributes to the accumulation of total organic carbon (TOC) in surface waters. TOC in surface waters is a known precursor of disinfection byproducts …

Routing, Localization And Positioning Protocols For Wireless Sensor And Actor Networks, Mustafa Akbas Jan 2013

Routing, Localization And Positioning Protocols For Wireless Sensor And Actor Networks, Mustafa Akbas

Electronic Theses and Dissertations

Wireless sensor and actor networks (WSANs) are distributed systems of sensor nodes and actors that are interconnected over the wireless medium. Sensor nodes collect information about the physical world and transmit the data to actors by using one-hop or multi-hop communications. Actors collect information from the sensor nodes, process the information, take decisions and react to the events. This dissertation presents contributions to the methods of routing, localization and positioning in WSANs for practical applications. We first propose a routing protocol with service differentiation for WSANs with stationary nodes. In this setting, we also adapt a sports ranking algorithm to …

Bio-Inspired, Varying Manifold Based Method With Enhanced Initial Guess Strategies For Single Vehicle's Optimal Trajectory Planning, Ni Li

Electronic Theses and Dissertations

Trajectory planning is important in many applications involving unmanned aerial vehicles, underwater vehicles, spacecraft, and industrial manipulators. It is still a challenging task to rapidly find an optimal trajectory while taking into account dynamic and environmental constraints. In this dissertation, a unified, varying manifold based optimal trajectory planning method inspired by several predator-prey relationships is investigated to tackle this challenging problem. Biological species, such as hoverflies, ants, and bats, have developed many efficient hunting strategies. It is hypothesized that these types of predators only move along paths in a carefully selected manifold based on the prey’s motion in some of …

Evaluation Of The Biodegradability And Toxicity Of Pca And Mpca, Juan Rueda Jan 2013

Evaluation Of The Biodegradability And Toxicity Of Pca And Mpca, Juan Rueda

Electronic Theses and Dissertations

The main types of hypergolic propellants used at Kennedy Space Center (KSC) are hydrazine (HZ) and monomethylhydrazine (MMH). HZ and MMH are classified as hazardous materials and they are also known to be potentially carcinogenic to humans; therefore, handling these substances and their waste is strictly regulated. The wastes streams from HZ and MMH have been estimated to be the main hazardous wastes streams at KSC. Currently at KSC these wastes are first neutralized using citric acid and then they are transported on public roads for incineration as hazardous materials. A new method using alpha ketoglutaric acid (AKGA) was proposed …

Virtual Interactions With Real-Agents For Sustainable Natural Resource Management, Tyler Pierce Jan 2013

Virtual Interactions With Real-Agents For Sustainable Natural Resource Management, Tyler Pierce

Electronic Theses and Dissertations

Common pool resource management systems are complex to manage due to the absence of a clear understanding of the effects of users’ behavioral characteristics. Non-cooperative decision making based on individual rationality (as opposed to group rationality) and a tendency to free ride due to lack of trust and information about other users’ behavior creates externalities and can lead to tragedy of the commons without intervention by a regulator. Nevertheless, even regulatory institutions often fail to sustain natural common pool resources in the absence of clear understanding of the responses of multiple heterogeneous decision makers to different regulation schemes. While modeling …

Near-Road Dispersion Modeling Of Mobile Source Air Toxics (Msats) In Florida, Kurt Westerlund Jan 2013

Near-Road Dispersion Modeling Of Mobile Source Air Toxics (Msats) In Florida, Kurt Westerlund

Electronic Theses and Dissertations

There is a growing public concern that emissions of mobile source air toxics (MSATs) from motor vehicles may pose a threat to human health. At present, no state or federal agencies require dispersion modeling of these compounds, but many agencies are concerned about potential future requirements. Current air pollution professionals are familiar with Federal Highway Administration (FHWA) and U.S. Environmental Protection Agency (EPA) requirements for dispersion modeling to produce predicted concentrations for comparison with appropriate standards. This research examined a method in which the potential near-road concentrations of MSATs were calculated. It was believed that by assessing MSATs in much …

Automatically Acquiring A Semantic Network Of Related Concepts, Sean Szumlanski Jan 2013

Automatically Acquiring A Semantic Network Of Related Concepts, Sean Szumlanski

Electronic Theses and Dissertations

We describe the automatic acquisition of a semantic network in which over 7,500 of the most frequently occurring nouns in the English language are linked to their semantically related concepts in the WordNet noun ontology. Relatedness between nouns is discovered automatically from lexical co-occurrence in Wikipedia texts using a novel adaptation of an information theoretic inspired measure. Our algorithm then capitalizes on salient sense clustering among these semantic associates to automatically disambiguate them to their corresponding WordNet noun senses (i.e., concepts). The resultant concept-to-concept associations, stemming from 7,593 target nouns, with 17,104 distinct senses among them, constitute a large-scale semantic …
