Investigating Grain Boundaries in BaCuS1-xSexF Using Impedance Spectroscopy

Creator:: Horgan, Briony
Abstract:: Impedance spectroscopy is a method of modeling materials with equivalent circuits to determine electrical properties, such as the resistivity and the dielectric constant. We explore impedance spectroscopy, both theoretically and experimentally through applying the method to samples of BaCuS1-xSexF. Grain boundary effects were dominant in the results, and although they...

Use of tethered prey for estimating the impact of the invasive European green crab

Creator:: Hauck, Laura L.
Abstract:: Various mollusks, including small bivalves and gastropod snails, are a common food source for intertidal crabs. Prey opening techniques used on hard-shell prey are dependent on claw size and morphology. For example, large, strong claws can crush a snail outright while smaller, weaker claws leave characteristic peels, pulls and upper...

How the Sun Drives Us: Photovoltaics in the US and Germany

Creator:: Hyde, Alison
Abstract:: With the realization that traditional means of providing useful energy have formidable environmental and economical repercussions, many counties have begun to explore more benign and sustainable energy sources—renewables. Photovoltaics (PV), a sub-group of renewable energy technologies, convert incident solar radiation into electrical power. Germany, the US and Japan are racing...

Development of a colorimetric test kit to determine enzymatically produced pyruvic acid in sweet onions

Creator:: Merrill, Dawn C.
Abstract:: Sweet onions are valued for their unique flavor and praised for their health and dietary character. Onion sweetness is perceived as the degree of pungency decreases. Pungency can be quantitatively determined in onions by measuring enzymatically produced pyruvic acid. The onion industry quantifies a sweet onion as one having a...

Effects of Perfluorinated Compounds on GnRH Gene Expression in vitro

Creator:: Bathke, Rebecca E.
Abstract:: Perfluorinated chemicals have been widely used in industry for their superior surfactant qualities. Because of their widespread usage and resistance to photolytic and biodegradation mechanisms, as well as their ability to undergo long-range atmospheric transport, these compounds have become ubiquitous in the world-wide water supplies. Of particular interest are perfluorooctanoic...

Immunohistochemistry Studies of Tumor Necrosis Factor Αlpha and Interferon Gamma Expression in Pseudocapillaria tomentosa Infected and Uninfected Zebrafish

Creator:: Lo, Lalee C.
Abstract:: Tumor necrosis factor alpha (TNF α) and interferon gamma (IFN γ) were initially recognized as inflammatory mediators produced by immune cells in response to infectious agents or foreign material. (1,5) However, over the past decade much research in mammalian species has indicated that these proteins also play key roles in...

Wind Energy: An Analysis and Comparison of Wind-Power Development in the United States and Spain

Creator:: Wilhelmsen, Scott
Abstract:: This essay seeks to analyze the wind-power policies of Spain, the United States and the world in order to better understand the past, present and future potentials of the resource. The growing demand for energy, concerns about global warming, and the need for increased energy security encourage societies to embrace...

Antibiotic Resistance Gene Transfer in Oysters as a Result of Fecal Pollution

Creator:: Cooper, Rebecca
Abstract:: Antibiotic resistance is an increasing problem in many species of bacteria today, with pathogens an important focus. Fecal contamination of shellfish is already a concern due to potential pathogens. This report examines the possibility of resistance gene transfer between microbes, due to fecal bacteria, within the oyster. In this study,...

Quantifying the Potential of Native Plants for Improving Pollination and Biological Control in Agroecosystems

Creator:: Winfield, Tammy L.
Abstract:: Agricultural areas can be inhospitable to the attraction and maintenance of beneficial insects like natural enemies and pollinators and this can result in a decrease in the ecosystem services of pollination and pest control that these insects supply. If habitat can be created and maintained on-farm, an increase in the...

Integration of embryonic zebrafish and passive sampling device extracts to explore effects of pesticide mixtures

Creator:: Corvi, Margaret
Abstract:: Pesticides are ubiquitous, with more than one billion tons of pesticide products used in the United States annually. These compounds are characterized by their toxic effects to the target organism; however, pesticides are also well known for their deleterious effects to non-target species. Because pesticides have ecological and human health...
