Design Of Multi-Electron Transfer Catalysts For The Reduction Of Trichloroethylene, Christopher Gerard Eman Ciptadjaya Dec 2007

Design Of Multi-Electron Transfer Catalysts For The Reduction Of Trichloroethylene, Christopher Gerard Eman Ciptadjaya

Masters Theses

For decades, organohalide (RX) compounds have been heavily used in the chemical and pharmaceutical industries and in agriculture as pesticides. Improper disposal of organohalides has resulted in their presence in the environment as pollutants, and they have therefore presented serious environmental and toxicological concerns. These organohalides have been associated with various health and environmental problems. Therefore, effective methods for their remediation are required. We have developed a multi-electron transfer (MET) catalyst consisting of flavin mononucleotide anchored to nanocrystalline mesoporous titanium dioxide (TiO2) thin films, and examined its reactivity toward the organohalide pollutant trichloroethylene (TCE). Various environmental factors were …

Fundamental Investigation Of Vesicle Bilayer Membrane Dynamics, Wilson Okumu Dec 2007

Fundamental Investigation Of Vesicle Bilayer Membrane Dynamics, Wilson Okumu

Masters Theses

We studied the bilayer of vesicles from dimyristolyphosphatidylcholine (DMPC), using nitrobenzoxadiazole (NBD) probes, attached to the head (NBD-PE) and the tail (NBD-PC) of phospholipid derivatives. We characterized the bilayer as it underwent reversible transition from the gel to the fluid through a phase transition range. The main phase transition was characterized by steady state and timeresolved fluorescence anisotropy, fluorescence intensity decrement and kinetics of dithionite reduction. We also studied DMPC with dihydrocholesterol. Differences between the surface and interior regions of the bilayer region were obtained. The activation barrier was enthalpic in the gel, entropic in the fluid phase and anomalous …

Use Of Native Seed Mixtures To Improve Erosion Control And Wildlife Habitat On Log Landings Following Timber Harvest In The Upper Elk Watershed Of West Virginia, Lisa R. Tager Dec 2007

Use Of Native Seed Mixtures To Improve Erosion Control And Wildlife Habitat On Log Landings Following Timber Harvest In The Upper Elk Watershed Of West Virginia, Lisa R. Tager

Graduate Theses, Dissertations, and Problem Reports (ETD)

Foresters in West Virginia follow BMP guidelines by reseeding retired log landings with inexpensive grasses that quickly provide erosion control. However, these grasses typically are not native nor do they provide high quality forage for wildlife. I developed 3 native seed mixtures for log landing reclamation that would maintain sediment control, as well as enhance wildlife habitat. These mixtures included an erosion control mixture, a wildlife mixture, and a wildflower mixture. I assessed sediment control, biomass production, vegetation structure, forage quality, and small mammal usage of my native mixtures and a commonly used, nonnative traditional mixture in 2005 and 2006. …

Expression Profiling Of Oocyte Specific Genes, Transcription Factors And Micrornas During Early Embryonic Development In Rainbow Trout (Onchorhyncus Mykiss), Raghuveer K. Ramachandra Dec 2007

Expression Profiling Of Oocyte Specific Genes, Transcription Factors And Micrornas During Early Embryonic Development In Rainbow Trout (Onchorhyncus Mykiss), Raghuveer K. Ramachandra

Graduate Theses, Dissertations, and Problem Reports (ETD)

Genes specifically expressed in oocytes are important for the development of oocytes and early embryos. By analyzing ESTs from a rainbow trout oocyte cDNA library, we identified a novel EST sequence that does not show homology to any sequences in the GenBank. Analysis of tissue distribution by RT-PCR revealed that this gene was only expressed in unfertilized oocytes. Sequencing of the EST clone identified a cDNA of 3163 bp. Northern blot analysis showed the novel gene has a single transcript of 3.4 kb. Additional 5' sequence was obtained by 5' RACE, extending the novel cDNA to 3333 bp. Analysis of …

Dna Damage Response Activated By Anti-Cancer Agent, Irofulven, Timothy D. Wiltshire Dec 2007

Dna Damage Response Activated By Anti-Cancer Agent, Irofulven, Timothy D. Wiltshire

Graduate Theses, Dissertations, and Problem Reports (ETD)

The DNA damage response is a complex network of signals that coordinate to protect cells from accumulating mutations that lead to the development of cancer. Upon the introduction of DNA damage from either environmental or endogenous sources, the DNA damage response coordinates the control of cell cycle with DNA repair mechanisms to ensure genomic integrity within the cell. Mutations in proteins in this pathway lead to genomic instability and early onset of cancer. BRCA1 is a protein that plays a critical role in response to DNA damage caused by ionizing radiation and is responsible for approximately 50% of inherited breast …

Identifying Synonymous Terms In Preparation For Technology Mining, Cherie C. Trumbach Dec 2007

Identifying Synonymous Terms In Preparation For Technology Mining, Cherie C. Trumbach

Management Faculty Publications

In this research, the development of a `concept-clumping algorithm' designed to improve the clustering of technical concepts is demonstrated . The algorithm developed first identifies a list of technically relevant noun phrases from a cleaned extracted list and then applies a rule-based algorithm for identifying synonymous terms based on shared words in each term. An assessment of the algorithm found that the algorithm has an 89—91% precision rate, was successful in moving technically important terms higher in the term frequency list, and improved the technical specificity of term clusters.

Influence Of Resource Availability On The Foraging Behavior Of Traplining Hummingbirds In Monteverde, Costa Rica, December 2007, Michelle Levesque Dec 2007

Influence Of Resource Availability On The Foraging Behavior Of Traplining Hummingbirds In Monteverde, Costa Rica, December 2007, Michelle Levesque

Monteverde Institute: Tropical Ecology and Conservation

Traplining hummingbirds have been observed to change their foraging behavior in response to a change in resource availability. Generally, trapliners change to territorial behavior when presented with an economically defendable resource. I investigated the degree to which aggressive behavior increases by observing changes in behavior frequency in response to increased resources. I observed that trapliner species showed an increase in aggressive behavior and a decrease in the total frequency of traplining behavior following the introduction of increased resources. My study also supports that traplining hummingbirds could switch their foraging behavior to territoriality when resources become economically defendable.

Atta Cephalotes (Formicidae) As A Reliable Bioassay For Anti-Fungal Compounds In Plants Of Monteverde, Costa Rica, December 2007, Annie Chisholm Dec 2007

Atta Cephalotes (Formicidae) As A Reliable Bioassay For Anti-Fungal Compounds In Plants Of Monteverde, Costa Rica, December 2007, Annie Chisholm

Monteverde Institute: Tropical Ecology and Conservation

Studies have shown Atta cephalotes (Formicidae) to be selective in choosing host plants, avoiding those that contain nonpolar secondary compounds harmful to their mutualistic fungus (Howard 1988). Due to this selectivity, several studies have found A. cephalotes to be a reliable bioassay tool for detecting antifungal properties of plants (Ozaki 1993; Taylor 1995). This experiment tests the acceptability of A. cephalotes towards six Costa Rican plants with known anti-fungal compounds. It was hypothesized that A. cephalotes would selectively avoid extracts of these plants. The frequency of removal of oat flakes dipped in the anti-fungal and control treatments was measured. A. …

Differences In Bark Beetle (Coleoptera: Curculionidae) Community Composition Within Cecropia Obtusifolia (Cecropiaceae) Petioles In Two Habitats In Monteverde, Costa Rica, December 2007, Amy Strauss Dec 2007

Differences In Bark Beetle (Coleoptera: Curculionidae) Community Composition Within Cecropia Obtusifolia (Cecropiaceae) Petioles In Two Habitats In Monteverde, Costa Rica, December 2007, Amy Strauss

Monteverde Institute: Tropical Ecology and Conservation

Cecropia obtusifolia trees shed leaves daily throughout the year, regularly dropping large, woody leaf petioles. These petioles serve as the perfect habitat for Scolytine bark beetles, which burrow in, lay their eggs, and feed on the moist, fibrous pith of the petiole (Wood 1983). Cecropia spp. are known to thrive in fragmented, edge habitats altered by human land use transformation (Bello et al 1996) but success rates of associated fauna, including Azteca spp. ants, scale insects and Scolytine beetles, are less understood. This study examined the bark beetle community composition, morphospecies richness, and abundance inside C. obtusifolia petioles. It also …

Behavioral Response Of Wrens (Troglodytidae) To Familiar And Unfamiliar Predator Playbacks, December 2007, Carl D. Johnson Dec 2007

Behavioral Response Of Wrens (Troglodytidae) To Familiar And Unfamiliar Predator Playbacks, December 2007, Carl D. Johnson

Monteverde Institute: Tropical Ecology and Conservation

Predator-prey interactions are important for determining fitness, especially including a prey species’ ability to distinguish a predator from a non-predator. In this study, I investigated how three wren species: the Plain Wren (Thryothorus modestus), the House Wren (Troglodytes musculus) and the Rufus-and-white Wren (Thryothorus rutilus) respond to familiar and unfamiliar predatory calls. The test subjects responded with higher warning call frequency to the predatory calls than the control (p<0.05). Wrens responded to the two predatory birds with similar call frequency, though there were varied responses in approach behavior. The fact that wrens respond to unknown predators similarly to known predators implies that a combination of both genetic inheritance and learning affects predatory birdcall recognition in wrens.

Spatial And Temporal Analysis Of Tornado Fatalities In The United States: 1880-2005, Walker S. Ashley Dec 2007

Spatial And Temporal Analysis Of Tornado Fatalities In The United States: 1880-2005, Walker S. Ashley

Faculty Articles, Papers, and Other Scholarship

A dataset of killer tornadoes is compiled and analyzed spatially in order to assess region-specific vulnerabilities in the United States from 1880 to 2005. Results reveal that most tornado fatalities occur in the lower–Arkansas, Tennessee, and lower–Mississippi River valleys of the southeastern United States—a region outside of traditional “tornado alley.” Analysis of variables including tornado frequency, land cover, mobile home density, population density, and nocturnal tornado probabilities demonstrates that the relative maximum of fatalities in the Deep South and minimum in the Great Plains may be due to the unique juxtaposition of both physical and social vulnerabilities. The spatial distribution …

Conversion Of Biomass Resource To Useful Forms Of Energy And Other Products, Latosha Johnson Dec 2007

Conversion Of Biomass Resource To Useful Forms Of Energy And Other Products, Latosha Johnson

Chemical Engineering Undergraduate Honors Theses

The United States is facing increasing pressure to find renewable energy sources due to rising energy costs. With world energy demand at an all time high, renewable energy has been thrust into the forefront of research as a means to mitigate this looming crisis. Throughout the United States, there is a large quantity of agricultural biomass that could be used to generate energy and lessen the dependence on diminishing resources. Specifically, animal feeding operations (AFOs) such as dairies generate large amounts of cow manure, which, when improperly handled, causes both air and water pollution. Currently, most manure is temporarily stockpiled …

Biohydrogen Production By The Hyperthermophilic Bacterium Thermotoga Neapolitana, Xiaohui Yu Dec 2007

Biohydrogen Production By The Hyperthermophilic Bacterium Thermotoga Neapolitana, Xiaohui Yu

All Dissertations

ABSTRACT Thermotoga neapolitana can use different sources of carbon and nitrogen for growth and produces biological hydrogen. Sources of carbon (glucose, sucrose, xylose, xylan, cellulose, cellobiose, starch, corn starch, beet bulp pellet, and rice flour) and nitrogen (yeast extract, fish meal, cottonseed meal, canola meal, linseed meal, and soybean meal) were compared. In the carbon studies, glucose, sucrose, rice flour, and xylan produced similar levels of hydrogen. In the nitrogen studies, Trypticase combined with alternative nitrogen sources can efficiently increases the yield of hydrogen produced by Thermotoga neapolitana. Yeast extract with trypticase as the dual nitrogen sources produced significantly increased …

The Emergence Of Sex, Ursula Goodenough Dec 2007

The Emergence Of Sex, Ursula Goodenough

Biology Faculty Research

Biological traits, the foci of natural selection, are by definition emergent from the genes, proteins, and other “nothing-buts” that constitute them. Moreover, and with the exception of recently emergent “spandrels,” each can be accorded a teleological dimension—each is “for” some purpose conducive to an organism's continuation. Sex, which is “for” the generation of recombinant genomes, may be one of the most ancient and ubiquitous traits in biology. In the course of its evolution, many additional traits, such as gender and nurture, have emerged. Patterns of sexual exchange are the basis for patterns of biological evolution and are central to the …

Charting The New Territory Of Adaptive Co-Management: A Delphi Study, Ryan Plummer, Derek Armitage Dec 2007

Charting The New Territory Of Adaptive Co-Management: A Delphi Study, Ryan Plummer, Derek Armitage

Geography and Environmental Studies Faculty Publications

Complex systems understanding implies a world characterized by dynamic, nonlinear interactions, discontinuities, and surprises. Such conditions are not amenable to conventional resource management approaches that stress command-and-control, and therefore, novel governance approaches are more suited to complexity and uncertainty are required. Adaptive co-management has emerged as an interdisciplinary response to this need, and blends the adaptive management and collaborative management narratives. However, concepts associated with adaptive co-management are relatively new and quickly expanding from multiple perspectives. The objective of this paper is to take stock of this relatively recent concept and synthesize current thinking in terms of: (1) the core …

Discovery: An Incremental Revolution, Rebecca Minnillo Dec 2007

Discovery: An Incremental Revolution, Rebecca Minnillo

Student Scholarship

Theorists such as Simon (1973), Popper (1959) and Kuhn (1962) have commented on the tendency to view scientific discovery as a "revolution" with a focus on an end result. In history, we "date" scientific discoveries as if they were events instead of the final outcome of a lengthy experimentation process. But, as Kuhn (1962:7) observed nearly a half-century ago, scientific revolution is, in fact, a "process rarely completed by a single man and never overnight". Rather, discovery most often occurs as a result of collaboration and interaction between researchers over protracted periods of time. Surprisingly, there is a paucity of …

Targeted Therapies In The Management Of Metastatic Bladder Cancer., Matteo Fassan, Edouard J. Trabulsi, Leonard G Gomella, Raffaele Baffa

Department of Urology Faculty Papers

The management of metastatic urothelial carcinoma (UC) of the bladder is a common and complex clinical challenge. Despite the fact that UC is one of the most frequent tumors in the population, long term survival for metastatic disease remains low, and chemotherapy is curative for only a small minority of patients. UC is genetically heterogeneous, and it is surrounded by a complex tissue microenvironment. The problems of clinical practice in the field of metastatic bladder cancer have begun to stimulate translational research. Advances in the understanding of the molecular biology of urothelial cancer continue to contribute to the identification of …

A Statistical Appraisal Of Disproportional Versus Proportional Microbial Source Tracking Libraries, Brian J. Robinson, Kerry J. Ritter, Rudolph D. Ellender Dec 2007

A Statistical Appraisal Of Disproportional Versus Proportional Microbial Source Tracking Libraries, Brian J. Robinson, Kerry J. Ritter, Rudolph D. Ellender

Faculty Publications

Library-based microbial source tracking (MST) can assist in reducing or eliminating fecal pollution in waters by predicting sources of fecal-associated bacteria. Library-based MST relies on an assembly of genetic or phenotypic "fingerprints" from pollution-indicative bacteria cultivated from known sources to compare with and identify fingerprints of unknown origin. The success of the library-based approach depends on how well each source candidate is represented in the library and which statistical algorithm or matching criterion is used to match unknowns. Because known source libraries are often built based on convenience or cost, some library sources may contain more representation than others. Depending …
