Hatchery O. mykiss that fail to emigrate to the ocean, referred to as residuals, present an ecological and genetic risk to naturally-produced species through resource competition, predation, and spawning interactions. The Lower Snake River Compensation Plan’s Wallowa stock steelhead program in northeast Oregon has established methods of reducing and quantifying...
Adenosine is considered to be a neuromodulator or
cotransmitter in the periphery and CNS. This neuromodulatory
action of adenosine may be observed as an anticonvulsant effect.
Dose-response curves for R-phenylisopropyladenosine (PIA),
cyclohexyladenosine (CHA), 2-chloroadenosine (2-ClAdo), Nethylcarboxamidoadenosine
(NECA) and S-PIA were generated against
PTZ seizure thresholds in the rat. The rank...
Following thermal neutron induced fission, supervised machine learning and temporal gamma-ray spectroscopy methods were used to identify differences in the delayed gamma-ray spectra of Pu-239 and U-235. The temporal gamma-ray spectroscopy method takes advantage of the time-dependent decay of fission products. Employing Spearman's rank-order correlation coefficient and without prior knowledge...
Traumatic brain injury (TBI) is a leading cause of death and disability in the United States. However, along with the increase in the occurrence of TBI, there has been a drastic decrease in the acute and long-term care provided for the TBI patient. This study provides information on the short-...
Contemporary spiritual tourism impacts many stakeholders including environmental ecosystems, tourists, tourist operators, and community members. Increasingly, in the era of the Anthropocene, there is a need for ethical guidance to inform spiritual tourism so as to mitigate social injustice and environmental degradation. This research project investigates the potential for the...
Headwater streams and their riparian zones are a common, yet poorly understood,
component of Pacific Northwest landscapes. I sought to describe the ecological significance of
headwater stream riparian zones as habitat for forest-floor invertebrate communities, and to
assess how alternative management strategies for riparian zones may impact these communities.
I...
The present thesis chemically examined 174 industrial North Staffordshire pottery fragments from an archaeological context, using Instrumental Neutron Activation Analysis (INAA). In an integrated effort to combine an archaeometric approach with archival research and traditional analysis methods, the purpose of the thesis was to link industrial pottery manufacturers recipes to...
Motivation
Relatively little is known about the evolution of mitochondrial genomes between Caenorhabditis species despite decades of research. Both the worldwide search for new nematode species and the effort to increase sequencing speeds require automated tools to quickly characterize and categorize large amounts of data.
Results
We developed an automated...
This monograph is focused around the controversy in the economic literature regarding the effects of income changes on labor force participation. In particular, this controversy arises from the opposing hypotheses: the "additional worker" and the "discouraged worker." Each hypothesis predicts different behavior in response to falling income or rising unemployment....
