Special Nuclear Material Classification and Mass Content Estimation Using Temporal Gamma-Ray Spectroscopy and Machine Learning Methods

Creator:: Curtis, Jessica R.
Abstract:: Improving the methods used for the detection and estimation of fissile material mass content is essential to nuclear security and safeguards to ensure special nuclear material (SNM) accountability, control, safety and security. With the continued expansion of the nuclear industry and the need for safe management of spent fuel, improving...

Using GIS to analyze the relationships between open space and property values

Creator:: Pavich, Steve M.
Abstract:: The conservation of open space will become increasingly important as populations expand and undeveloped land is converted to urban uses. The benefits derived from open space conservation include protecting and improving water quality, providing wildlife habitat, maintaining scenic amenities and rural character, and supplying certain recreational opportunities. This study utilizes...

Factors affecting the regrowth of Himalya (sic) blackberry (Rubus armeniacus)

Creator:: Jones, Daniel Karl
Abstract:: Himalaya blackberry (Rubus armeniacus) is a widespread, exotic, invasive plant now common over much of western Oregon and Washington. An observational experiment revealed that disturbance to a monoculture of Himalaya blackberry allows the soil seed bank to be expressed and return the inhabited area to an earlier successional stage. This...

Characterizing the neutron spectra in various irradiation facilities within the Oregon State University TRIGA ® Reactor

Creator:: Ashbaker, Eric
Abstract:: The Oregon State University TRIGA® Reactor (OSTR) has a number of irradiation facilities providing a wide range of neutron energies and fluxes. These facilities include a pneumatic transfer tube, a rotating rack, a thermal column, four beam ports, in-core irradiation tubes, a clyogenic gas transfer system and a large vault...

Simulating past, present, and future changes in ENSO : a model evaluation and data-model comparison

Creator:: Alder, Jay R.
Abstract:: This thesis presents the results of a formal evaluation of a new AOGCM, GENMOM, demonstrating its ability to simulate present-day climate and ENSO dynamics. The model is applied to simulate climate for the Last Glacial Maximum, deglacial, and Holocene time periods. The model output is evaluated against the best available...

Vegetative effects of RNAi-suppression of the poplar homolog of LEAFY in the field

Creator:: Jacobson, Jeremy
Abstract:: Due to public and regulatory restrictions, genetic containment technology is critical for research and development of transgenic trees in forestry. A multi-year field trial demonstrated that the RNAi-LFY construct successfully induces sexual sterility in 6K10 poplar (Populus alba) without visible effects on vegetative development. However, its limited number of replicates...

Directing ecological succession : the role of competition in restoring semi-arid grasslands dominated by invasive plants

Creator:: Mangla, Seema
Abstract:: Successful ecosystem restoration requires an understanding of the ecological processes directing succession. One of the challenges in the semi-arid grasslands of western United States is replacement of native species by invasive annual grasses. Solutions to this problem require identifying and manipulating ecological processes that direct succession to favor desired vegetation....

Beaches, Wine, and Weed: Economic Implications of Land Use Change in Oregon

Creator:: Beasley, W. Jason
Abstract:: The economic analysis of land use decisions provides insight into incentive structures faced by landowners and the impacts of landowner decisions on others. Qualifying and quantifying these incentives and impacts offers insight into the relevant characteristics of decision-making. In turn, this allows the researcher to model and predict land use...

Stephen Biko's Rhetorical Vision of Black Consciousness

Creator:: Fergusson, Julie K.
Abstract:: Stephen Biko was a black leader in South Africa who died in police custody on September 12, 1977. Biko's death echoed within the Republic of South Africa and around the world, showing that racial tensions in that country were severe. At his death he was a hero to the black...

Overexpression of the GROWTH REGULATING FACTOR 4-GRF-INTERACTING FACTOR 1 Transcription Factor Chimera Modifies Transformation and Regeneration Efficiency in Populus and Eucalyptus

Creator:: Ryan, Nathaniel W.
Abstract:: Transformation is a major bottleneck for genetic engineering and gene editing in forest tree species. This includes most genotypes of Populus and Eucalyptus, which are some of the world’s most widely-cultivated genera of plantation forest trees. To provide new tools for transformation, I tested the transcription factor-protein chimera consisting of...
