Real Time Temporal Spectroscopy for Characterizing Special Nuclear Material

Creator:: Mannino, Mitch
Abstract:: Characterizing special nuclear material (SNM) is critical for nuclear security and non-proliferation. Temporal spectroscopy is a novel and efficient method for characterizing relative material content of special nuclear material. Fission products produced by SNM after being irradiated by a thermal neutron beam can have different half-lives, but can contribute to...

The Evaluation of Cementitious Pore Solution Composition and Electrical Resistivity Using X-ray Fluorescence (XRF)

Creator:: Tsui Chang, Marisol
Abstract:: Interest in performance specifications has been growing in the civil and construction industry in the past decade. One major focus area has been on understanding how to prolong the service life of concrete structures, since repair and rehabilitation of existing infrastructure have cost many trillions of dollars. Deterioration mechanisms such...

Power Efficient Hybrid Architecture for High Resolution Analog-to-Digital Converters

Creator:: Zhang, Hui
Abstract:: Analog-to-digital converters (ADCs) are the key building block for sensor applications, such as wireless communications and digital electronics. These applications require ADCs to have medium to high accuracy (normally from 10-14 bits) and relatively low signal bandwidth (ranging from 100Hz-150kHz). Since these applications are often powered by batteries, high power...

Efficacy of Empirical Seed Zones: Pseudoroegneria Spicata Reproductive Phenology & Seedling Stage Traits

Creator:: Prive, Kathryn A.
Abstract:: Ecological restoration is needed to mitigate losses to biodiversity. Restoration success is enhanced through the use of native plant materials that are genetically diverse and locally adapted. Seed transfer zones have been developed to delineate geographic areas where native seed can be collected and distributed with reduced risk of maladaptation....

The Transfer Student Experience : Sense of Belonging at Four-Year Institutions

Creator:: Lee, Melissa A.
Abstract:: This study examines the ways in which community college transfer students develop a sense of belonging at the four-year institution. This inquiry was guided by a constructivist epistemology and qualitative methodology. Data was collected through conducting one-on-one interviews and focus groups to gather information on how transfer students develop a...

Effects of Secondary Salinization on Three Coastal Breeding Amphibians in Oregon: Taricha granulosa, Hyliola regilla, and Rana aurora

Creator:: Goddard, Amanda L.
Abstract:: Due to threats of secondary salinization caused by increased saltwater intrusion upstream associated with climate change, this thesis examines how salinity affects the development and oviposition site selection habits of three Oregon coastal breeding amphibians, the Roughskin Newt (Taricha granulosa), the Northern Red-legged Frog (Rana aurora) and the Pacific Treefrog...

‘Difficult to place’? Understanding child and family level factors affecting placement stability for youth in foster care

Creator:: Probert, Kylee
Abstract:: Introduction: Youth in foster care face greater rates of trauma and subsequent mental health challenges (Bruce et al., 2009; O’Neill et al., 2012; Seltzer et al., 2012; etc.) that place increased burden on their caregivers (Daniel, 2011; McKeough et al., 2017), suggesting that these specific groups of youth in foster...

MAN 'aging Water Resources of the Deschutes River Basin

Creator:: Taganova, Jahan
Abstract:: In the last two decades, there has been an increase in substantial body of work on the inclusion of women in the water management and governance field. However, these scholarly inquiries have mostly focused on cases from the Global South, where women are still underrepresented in decision-making positions in the...

Monotonic and Cyclic Testing of Cross-Laminated Timber Diaphragms

Creator:: Beairsto, Cody J.
Abstract:: Mass timber is emerging as a viable form of construction around the world in new markets for wood buildings. The entrance into these markets has driven the demand for more knowledge to enable designs alongside other structural materials such as steel and reinforced concrete. Large, in-plane tests on cross-laminated timber...

Spatiotemporal Assessment of Crop Histories in the Pacific Northwest

Creator:: Kumbhakar, Ishika G.
Abstract:: The cultivated potato (Solanum tuberosum) is one of the most important food crops in the United States, as well as globally. As demand rises, growers in the Pacific Northwest are revisiting their crop management strategies to determine whether there are additional ways to enhance crop productivity while managing plant and...
