Dogs, Death, and Dietary Breadth: Insights into the Macroecology and Macroevolution of Canidae

Creator:: Tanis, Brian P.
Abstract:: The size, shape, and stability of a species’ dietary niche can both influence and reflect a variety of biological patterns, including species interactions, extinction risk, and ecosystem function. This is particularly apparent when dietary changes manifest at ecosystem and clade scales to profoundly affect macroecological and macroevolutionary trajectories. However, many...

An Investigation into the Production of Longer Hydrocarbons, Synthesis Gas, and Ammonia via a Nonthermal Plasma Microreactor

Creator:: Reddick, Ian T.
Abstract:: Nonthermal electrical plasmas can allow energy intensive reactions to occur without the use of high operating temperatures or pressures. This is because the collisions of electrons accelerated through an electric field with molecules is the cause of reactions as opposed to thermal collisions between molecules. In this study, the production...

Utilization of Renewable Energy via Thermochemistry

Creator:: Lei, Fuqiong
Abstract:: Utilization of solar energy or wind energy for electricity production is inherently challenging due to the diurnal and seasonal variations and normal intermittency. Effective, high efficiency storage methods need to be developed for further advancing renewable energy utilization. Endothermic chemical processing and thermochemical energy storage can be both employed as...

Production of C4-C10 Hydrocarbons from CO₂, H₂O, CO, H₂ and CH₄ Utilizing DC Glow Discharges, Catalytic Rapid Temperature Pulsing in Micro-Scale Reactors.

Creator:: Mohamed, Omar M.
Abstract:: This thesis experimentally determines the feasibility to creating C4 to C10 hydrocarbons from CO2, CO, H2, H2O and CH4. This is done in two steps, the initial step is the formation of ethylene through DC electrical glow discharge at ambient pressure while the second step is through temperature pulse controlled...

Ascorbylation- the biological relevance of covalently bound ascorbic acid

Creator:: Kesinger, Nicholas G.
Abstract:: Ascorbic acid, or vitamin C, is well known as a co-factor for proline-hydroxylase and as an anti-oxidant. However, it is also capable of forming covalent bonds, particularly in the role of a nucleophile, henceforth termed 'ascorbylation'. The ascorbylation of electrophiles can occur under physiological conditions. Furthermore, there are a number...

Investigating Demographic and Evolutionary Factors Important for Fish Reintroduction

Creator:: Sard, Nicholas M.
Abstract:: Reintroduction programs are used to re-establish species back into their historical habitat. Most reintroduction programs have failed and few papers have evaluated factors that may be important to Pacific salmon. The 158 meter tall Cougar Dam has blocked Chinook salmon (Oncorhynchus tshawytscha) from accessing 40 kilometers of historical spawning and...

Age-related decrease in resilience against acute redox cycling agents: Critical role of declining GSH-dependent detoxification capacity

Creator:: Thomas, Nicholas O.
Abstract:: Over the past century, life expectancy in the United States has dramatically increased leading to an increasingly aging population with people reaching, and spending more years in ‘old age’. While this unprecedented shift in population demographics represents great strides for humanity, it is not without cost. One consequence of longer...

International comparison and evaluation of agricultural productivity growth

Creator:: Rada, Nicholas E.
Abstract:: Long-run food price changes respond to long-run changes in food demand, quasi-fixed and variable production factors, and agricultural productivity. Recent global food-price volatility puts a renewed spotlight on the trends and sources of any agricultural productivity growth. Because food prices’ most critical effects are on human hunger, it is especially...

How Behavior, Physiology, and Ontogeny of Klamath Redband Trout Shape the Functionality of Habitats in a Landscape of Temperature Extremes

Creator:: Hahlbeck, Nicholas J.
Abstract:: Climate change is a global phenomenon, but natural selection occurs within landscapes. A central tenet of landscape ecology is that mobile species depend on complementary habitats, which are insufficient in isolation, but combine to support animals through the full annual cycle. For coldwater fishes, it is widely assumed that maximum...

From the Shoreface to the Foredunes : Coastal Morphodynamics Across the Land-Sea Interface

Creator:: Cohn, Nicholas T.
Abstract:: Coastal flooding and erosion are major concerns for low lying coastal communities -- particularly in light of accelerated sea level rise and climate change. To improve quantitative understanding of the physical drivers of both flooding and coastal landscape change, this dissertation explores coastal morphodynamics bridging the land-sea interface on modally...
