Validation of radiographic automatic exposure control device testing in the era of filmless radiography : and new variables associated with testing

Creator:: Allman, Robert M.
Abstract:: The exposure needed for a clinically useful image requires much less precision when using digital radiography (DR) than when using screen/film (SF) radiography. The Automatic Exposure Control (AEC) device was developed for ensuring accurate and precise exposures with SF technology. This thesis evaluates the importance of the AEC device in...

Students' perception of the design of common space and its role in sense of community and belonging

Creator:: Knight, Megan Michele
Abstract:: Students are now required to live a minimum of their freshman year in the residence halls. This time spent in the residence halls is a time of transition; living on their own, for what may be the first time for many, can be a struggle. Students are adjusting to a...

Intraseasonal Oscillations of ~20 days Revisited: The Jet Stream and its Ecological Implications along the Oregon Coast

Creator:: Herweck, Kendra
Abstract:: Intraseasonal oscillations in the atmosphere-ocean system can affect weather patterns and regional ecosystems. In turn, these oscillations can be affected by climate variability, resulting in additive and/or non-linear responses of regional ecosystems to climate forcing. In the Northern California Current, a strong correlation was identified between the location of the...

Genomic mapping of efflux pumps in Listeria monocytogenes and their contribution to cadmium and fluoroquinolone tolerance

Creator:: Domen, Andrea
Abstract:: Listeria monocytogenes is the third most deadly foodborne pathogen in the United States. The young and elderly, as well as pregnant and immunocompromised people are the population most susceptible to serious illness and death from listeriosis infections. Unlike most foodborne pathogens, L. monocytogenes does not live a solely enteric lifestyle....

Prevalence and Characterization of Listeria spp. Recovered from Pacific Northwest Produce Handling and Processing Facilities

Creator:: Jorgensen, John
Abstract:: Foodborne illness in the United States continues to be a complex and recurring issue despite our increased understanding of the pathogenic microorganisms responsible. Foodborne illness outbreaks and product recalls linked to pathogenic bacteria have been more frequent in the produce industry (e.g. fruits and vegetables) in the last ten years....

New Configurations of Silicone Passive Sampling Devices: Quantifying Feline and Firefighter Chemical Exposures

Creator:: Poutasse, Carolyn M.
Abstract:: Silicone wristbands are passive sampling devices (PSD) that sequester bioavailable organic chemicals in the environment. In environmental health studies, silicone wristbands are easy to wear and can provide personal exposure data about complex chemical mixtures. This dissertation includes an overview of PSD technology, a literature review of current wristband research...

Comparison of total dose to individuals from temperate and arid environments

Creator:: Elmore, Brockway F., II
Abstract:: This paper analyzes the decision-making process utilized in temperate environments for building nuclear facilities and whether it was going to be applicable to nuclear facilities built in arid environments. To answer this question, the total dose to individuals from arid and temperate environments were compared using RESRAD-OFFSITE and changing the...

Estimating Air Pollutant Emissions for Nonroad Equipment using EPA MOVES – Case Study of a Building Project

Creator:: Boddi Reddy, Sai Akhila
Abstract:: Total emissions from the US contribute 15% to the global emissions. The construction industry is a major source of the exhaust emissions produced. Use of light-duty vehicles and heavy-duty trucks for various construction activities contributes 83% to the total greenhouse gases produced. Construction equipment comprises of on-road and non-road equipment,...

Human Error in Helicopter Accidents : Understanding the Manifestation of Human Error across Helicopter Missions

Creator:: Morowsky, Katarina A.
Abstract:: Human error is responsible for the majority of accidents in complex environments including helicopter operations. To reduce the overall accident rate throughout the helicopter industry, we must first understand how helicopter missions differ from one another and what errors lead to accidents. The research documented in this dissertation involved a...

Neutron radiography and tomography : determining and optimizing resolution of neutron sensitive multi channel plate detectors

Creator:: Williams, Walter James
Abstract:: The objective of this work was to determine and optimize the resolution of a neutron sensitive Multi-Channel Plate (MCP) detector in order to determine its capabilities in radiography and tomography. The Oregon State University, Neutron Radiography Facility added an MCP Detector in 2012 in order to analyze these capabilities. The...
