Petrology and geochemistry of the Emigrant Pass volcanics, Nevada : implications for a magmatic-hydrothermal origin of the Carlin gold deposits

Creator:: Johnson, Curtis L.
Abstract:: The Emigrant Pass volcanics (EPV) are a 38.3 to 36.4 Ma calc-alkaline volcanic center that erupted andesite and dacite, and a late series of felsic dikes along the south flank of the Carlin gold district in north-central Nevada. The EPV includes dacite and rhyolite porphyry dikes indistinguishable from porphyry dikes...

Deconvolving the sedimentary phases of barium using flow-through time-resolved analysis

Creator:: Hsieh, Chih-Ting
Abstract:: The distribution of barite (BaSO₄) in marine sediments has long been studied as a proxy for paleoproductivity. While pure barite is known to be a stable mineral in oxic sediments, it is also known that variations in the Sr/Ba ratio influence its solubility and liability during early diagenesis. To extract...

Determination of Total Nucleotides, Nitrogenous Bases and Degradation By-Products with Respect to Various Processing and Preservation Techniques for Alaska Pollock (Gadus chalcogrammus) and Yellowfin Sole (Limanada aspera)

Creator:: Nelson, Kevin A.
Abstract:: The primary goal of this research was to determine the concentration and composition of nucleotides, as nucleoside monophosphates and nucleobases, in the underutilized reproductive organs (milt and roe) of Alaska pollock (Gadus chalcogrammus) and yellowfin sole (Limanda aspera). Changes in concentrations of these nucleotides and nucleotide analogs were observed with...

Deposition and characterization of transition metal oxides from aqueous solution

Creator:: Betterton, Sharon A.
Abstract:: The aqueous chemistries of two transition metal cations, Zr⁴⁺ and Nb⁵⁺, are examined and then used to develop inorganic precursor solutions. The oxides of these cations (ZrO₂ and Nb₂O₅) are deposited and characterized, and their morphological and optical properties discussed. Due to the obstacles created by niobium's aqueous chemistry, an...

Experimental Evolution of Roundup Resistance in Outcrossing Populations of Saccharomyces cerevisiae

Creator:: Hanson, Chloe C.
Abstract:: Evolve & Resequence (E&R) experiments subject laboratory populations to environments controlled by investigators, who then document the phenotypic and genomic changes that take place over many generations. These experiments provide powerful tools for testing of a wide variety of evolutionary questions, especially questions about the nature of adaptive traits. While...

Risk Assessment of Salmonella in Raw Hazelnuts and use of Propylene Oxide as a Potential Mitigation Strategy

Creator:: Wright, Daniel G.
Abstract:: Multiple outbreaks of foodborne illness (Salmonella and E. coli O157:H7) have been associated with tree nuts and tree nut products since the early 2000s. In response to these outbreaks and many others in fresh produce and peanut butter, Congress created and passed the Food Safety Modernization Act (FSMA) to require...

Evaluation of the Performance of Lateral Spread Displacement Empirical Models for Subduction Zone Earthquake Case Histories

Creator:: Bunn, Michael
Abstract:: Lateral spread is a pervasive type of liquefaction-induced ground failure that occurs on gentle slopes or near free-faces, such as river channels. Resulting horizontal displacements can reach up to several meters, and can be considerably damaging to foundations, bridges, roadways, pipelines, etc. In the 1990s, Bartlett and Youd (1992a, 1995)...

Making the Unconscious Unconscious : Reclaiming Microinteractions for People with Motor Disabilities

Creator:: Lazewatsky, Daniel A.
Abstract:: Numerous diseases and injuries can limit a person's ability to perform everyday tasks -- things like getting dressed, bathing, and eating. Anything that requires physical activity can be affected; even simple things like turning on the lights can become difficult or impossible. Until recently, the only way for a person...

Tactics for enhancing conservation biological control of twospotted spider mites, Tetranychus urticae Koch, in Pacific Northwest hop yards

Creator:: Woods, Joanna L.
Abstract:: The twospotted spider mite, Tetranychus urticae Koch (Acari: Tetranychidae), is a worldwide pest of numerous agronomic and horticultural plants. Conservation biological control of this pest can be unreliable due to asynchrony of natural enemies and certain horticultural practices that have a direct or indirect affect on natural enemies and the...

Impact of malolactic fermentation on red wine color and color stability

Creator:: Burns, Tresider R.
Abstract:: Malolactic fermentation (MLF) is an important step in the production of wines and is commonly performed in red or cool climate wines to reduce acidity. In this study the impact of MLF on red wine color and the ability of Oenococcus oeni to degrade compounds important to the development of...
