Calculating characteristic timescales for environmental decoherence in the presence of thermal gravitons

Creator:: Nelson, Hunter
Abstract:: Different models show the effects of environmental decoherence on a quantum system due to various environments of interest. One important quantity within these models is the decoherence time, which tells us how quickly environments wash away the coherence of local measurements. We can describe this effect as the quantum system...

The particle on a ring in polymer quantum mechanics : a quantum cosmology analogue on a compact space

Creator:: Siebersma, Maxwell R.
Abstract:: Loop quantum gravity is a framework for quantizing general relativity which imposes a discrete structure on space. In exploring the structure of loop quantum gravity, researchers have investigated loop quantum cosmology, a toy model with reduced degrees of freedom while maintaining a discrete space. Polymer quantum mechanics is a framework...

Investigating polymer quantum mechanics : mathematical formulation, the particle on a ring, and time evolution

Creator:: Seibert, Basie S.
Abstract:: Loop quantum gravity is a theoretical framework which aims to quantize general relativity. One of the unique aspects of this theory is that it imposes a discrete structure on space-time. One toy model of loop quantum gravity is loop quantum cosmology, which maintains the idea of a discrete spatial structure...

Expression of serotonin, chromogranin-A, serotonin receptor-2B, tryptophan hydroxylase-1, and serotonin reuptake transporter in the small intestine of dogs with inflammatory bowel disease

Creator:: Bailey, Candice
Abstract:: The neuroendocrine system of the gut plays a significant role in regulating intestinal motor and sensory functions, as well as modulating inflammation in the intestine. The intestinal mucosa is the dominant site of serotonin (5HT) synthesis in mammals, with more than 95% of the intestinal 5HT being present in the...

The Consistent Histories Approach to the Stern-Gerlach Experiment

Creator:: Wilson, Ian
Abstract:: Standard quantum mechanics makes foundational assumptions to describe the measurement process. Upon interaction with a “classical measurement apparatus”, a quantum system is subjected to postulated “state collapse” dynamics. We show that framing measurement around state collapse and ill-defined classical observers leads to interpretational issues, and artificially limits the scope of...

A Generalized Scheme for Creating Regge Calculus Models of General Relativity

Creator:: Hanson, Ben R.
Abstract:: Solutions to Einstein's equations are usually found by considering ideal, simplified models. However, if the real world always matched ideal physics models, then farmers would milk black and white spheres. To combat this, Regge calculus was developed as a numerical approximation scheme for general relativity. In Regge calculus curved manifolds...

Anaerobic biodegradation of the cyclic nitramines, RDX and HMX, by ovine ruminal microbes

Creator:: Eaton, Hillary L.
Abstract:: Cyclic nitramines released into all environmental compartments through anthropogenic activities are toxic and possibly carcinogenic and mutagenic. Soils on military ranges, located throughout the world in various climatic regions and close to human activities, are especially susceptible to cyclic nitramine contamination. The properties of soils on military ranges will directly...

Sources of variability in duration of anesthesia with brevital sodium in snakes

Creator:: Preston, Daniel L.
Abstract:: Variability in the depth and duration of anesthesia in individuals within a species is frequently observed, yet few studies have investigated its causes in reptiles. To evaluate the potential causes of variability in reptile anesthesia, I conducted experiments to test for effects of body temperature, body composition and time post-feeding...

A Report on the Goat Industries of Oregon

Creator:: Lamphere, Charlotte A.
Abstract:: Goats were the first livestock species to be domesticated by humans and continue to function as a key source of protein and economic value for many communities. In the sixteenth century, Spanish colonists brought goats to the Americas. Unlike other nations, the United States did not maintain a significant market...

Ruminal Biodegradation of Heterocyclic Toxic Compounds

Creator:: Tanaree, Dan D.
Abstract:: Cyclic nitramines are a class of compounds that include most of the commonly used explosives today. These are among the most common toxicants released into the environment as a result of human activity, generated on military ranges, battlefields, and production sites. Of these, hexahydro-1,3,5-trinitro-1,3,5- triazine (RDX) is of particular interest,...
