This study was undertaken to determine the sensory differences in high pressure vs. heat processed food systems after storage at ambient and refrigerated temperatures as determined by a trained sensory panel. Spanish rice and spaghetti with meat sauce were prepared and treated with heat and with high pressure processing (HHP)....
This dissertation uses argon geochronology and cosmogenic nuclide surface exposure dating methods to address three research questions. The first question concerns a geomagnetic instability recorded in lava flows on the island of Floreana in the Galapagos Archipelago. Changes in the Earth’s magnetic field (intensity and orientation) occur frequently throughout geologic...
Mitigating for increased human impact to the seafloor associated with resource extraction activities and renewable energy development can benefit from an understanding of the distribution of sensitive marine benthic species. Habitat suitability predictive modeling is a cost effective statistical tool to infer species distribution patterns from constrained sampling locations. However,...
In this thesis I present the results of a comprehensive assessment of the Pacific-North American (PNA) teleconnection pattern in general circulation models (GCMs) and a regional climate model (RCM). The PNA teleconnection pattern is a quasi-stationary wave field over the North Pacific and North America that has long been recognized...
I surveyed epiphytic macrolichens and bryophytes in six stands in each of seven riparian stand types in the Oregon Coast Range. This study (Chapter 2) describes the association of epiphytes with stand types and the corresponding potential of forest canopy conversions to affect epiphyte communities. Species composition, diversity, and representation...
Research suggests that, in individuals with carpal tunnel syndrome (CTS), low
plasma pyridoxal 5'-phosphate (PLP) concentrations are related to an increased incidence
and severity of symptoms associated with CTS. This study was designed to determine
the relationship between plasma and red blood cell PLP concentrations and the severity
and incidence...
This study investigated the impact of team-teaching in coordinated-studies programs
(CSPs) on community college faculty in three instructional development domains: personal,
social, and professional. Grounded in a social-constructivist theoretical framework, this
research examined whether development occurs best experientially, in collaborative
communities of knowledgeable peers. CSPs are team-taught interdisciplinary, problem-solving
enterprises...
Multiple Sclerosis (MS) is a debilitating, degenerative, and chronic disease that affects over 350,000 individuals in the United States. Symptoms such as fatigue, spasticity, weakness, gait and visual disturbances, numbness and balance problems affect many with MS on a regular basis. There are literally an infinite number of combinations of...
The operational processing of MODIS imagery to produce the MOD06 cloud product is based on the assumption that cloudy 1-km pixels are overcast. This assumption is examined using a partly cloudy pixel retrieval scheme, which allows for fractional cloud cover within the 1-km pixels. Cloud flags attached to 250-m MODIS...
Most climate models predict a weakening of the North Atlantic thermohaline circulation for the 21st century when forced by increasing levels of greenhouse gas concentrations. The model spread, however, is rather large, even when the forcing scenario is identical, indicating a large uncertainty in the response to forcing. In order...
