In vivo assessment of nanomaterial-induced toxicity using embryonic zebrafish

Creator:: Usenko, Crystal Y.
Abstract:: Due to their unique physical, chemical, and magnetic properties, nanomaterials have great potential for industrial development. There is a pressing need to develop rapid whole animal-based testing assays to assess the potential toxicity of engineered nanomaterials. To meet this challenge the embryonic zebrafish model was employed to determine the toxicity...

Entre crítica e imaginación: El contexto de las relaciones de México y Estados Unidos desde la perspectiva de La frontera de cristal y Gringo viejo

Creator:: Hansen, Tobin M.
Abstract:: What historical and political reality is reflected in the novels Gringo viejo and La frontera de cristal? What is revealed when the characters, plot, and setting of the novels are analyzed against research of the context of U.S.-Mexico relations? We begin to explore these questions by studying three periods crucial...

Response of needle-litter decomposition and soil nitrogen mineralization to logging-debris manipulation and competing vegetation control in western Oregon and Washington

Creator:: Meehan, Nathan Andrew
Abstract:: Growing societal demand for forest products is pressuring managers to increase productivity from a finite land area, and it is expected that increased supply will come mostly from expansion of intensively managed stands. The USDA Forest Service and numerous collaborators created the Long-Term Soil Productivity (LTSP) network of research sites...

Geochemical and helium isotopic variability within the Lau Basin

Creator:: Goddard, Charlotte Ives
Abstract:: This research incorporates geochemical and helium isotopic analyses of Lau Basin volcanic glasses, along with helium isotopic analyses of water column hydrothermal plumes to better understand the processes that control the formation and evolution of this backarc basin. Lavas newly collected from the four southernmost segments of the Valu Fa...

Thin-film transistors with amorphous oxide channel layers

Creator:: Grover, Manan S.
Abstract:: In recent years, a new class of high-performance thin-film transistors (TFTs) has emerged comprising amorphous oxide channel materials composed of heavy-metal cations (HMCs) with (n-1)d¹⁰ns⁰ (n ≥ 4, where 'n' refers to the row of the periodic table) electronic configuration. This thesis is devoted to the fabrication and characterization of...

The Protection of Groundwater - Specifically Oil and Gas Contamination

Creator:: Stash, Karen M.
Abstract:: Groundwater is a vital resource and efforts must be made to protect its quality. In certain areas, its quality has been threatened by the introduction of oil and gasoline, many times originating from underground storage tanks. Massachusetts has directly reacted to this concern about groundwater quality by promulating a Massachusetts...

Oxidative desulfurization of dibenzothiophene with tert-butyl hydro peroxide in a photochemical micro-reactor

Creator:: Hebert, Eilleen M.
Abstract:: Sulfur content in fuels is an increasingly critical environmental issue. Hydrodesulfurization removes sulfur from hydrocarbons; however, further desulfurization is necessary in fuels. New methods are required. In this study, micro-scaled single phase oxidative desulfurization is explored. An ultraviolet light-assisted micro-reactor is introduced for desulfurization of dibenzothiophene. Dibenzothiophene is mixed with...

Chemical modification of wood : dimensional stabilization of viscoelastic thermal compressed wood

Creator:: Gabrielli, Christopher P.
Abstract:: The tendency of wood to shrink and swell with changing moisture content remains as one of the most significant challenges to using wood in its many applications. Viscoelastic Thermal Compression (VTC) has been shown to significantly increase the density, strength and stiffness of wood. However, dimensional stability is still a...

Optimal soaring by a small autonomous glider

Creator:: Kyle, Jason A.
Abstract:: Extending the flight time of an autonomous unmanned air vehicle by soaring is considered. A suboptimal controller is developed and successful static soaring is demonstrated with a 6 degree of freedom glider model. Altitude gain rates of between ¼ and ½ m/s are achieved with this simple implementation. A hybrid...

A study of opposing mixed convection in the GRTS and in downward pipe flows using the FLUENT CFD code

Creator:: Jackson, R. Brian
Abstract:: Downward flow opposing mixed convection conditions have been studied using the FLUENT CFD code. This work was comprised of two primary objectives. The first was to study core channel flow reversal susceptibility in the Gas Reactor Test Section (GRTS) at low flow conditions. The second objective was the development of...
