Acceleration of Long-Range Ordering in NiCrFe Alloys Via Proton Irradiation

Creator:: Evered, Cole E.
Abstract:: This work explores the hypothesis that proton irradiation is a feasible alternative to simulate accelerated thermal aging for Ni2Cr long-range ordered phase formation within NiCr and NiCrFe alloys. In this study, various model alloys and commercial alloys 690 and 690+P (0.01 wt.% P) were subject to 2 MeV proton irradiation...

Machine Learning and Optimization Applications in Agriculture

Creator:: Molotkov, Alexander
Abstract:: The ever-increasing global population presents looming problems for the field of agriculture. Global food demand will, at some point, increase to the point where there is not enough crop-ready land to keep up. This creates an additional incentive, other than economics, for growers to increase their yield-per-acre and make sure...

Alternate Methods for the Extraction and Measurement of Pore Solution in Fresh Concrete

Creator:: Biever, Joseph
Abstract:: Knowledge of the pore solution composition and pore solution resistivity can be helpful for determining the durability of concrete structures. Most notably, pore solution resistivity can be used in the calculation of the formation factor of concrete, which is a ratio of the electrical resistivities of concrete and its pore...

Fish for the Future: Fisheries Conservation Developments and Lessons Learned from Squaxin Tribal, and Washington State, Salmon Fisheries Management

Creator:: Peters, Joseph C.
Abstract:: Washington State fisheries and Washington State Treaty Tribes are becoming increasingly restricted in harvest of wild salmon due to US Endangered Species Act listings of salmon species, marine mammal predation by both ESA listed Southern Resident Killer Whale (SRKW) and US Marine Mammal Protection Act protected pinnipeds, salmon habitat destruction,...

Spectroscopic Ellipsometry on Thin Films of TiO2: Comparing Cauchy and Cody-Loretnz Models in CompleteEASE

Creator:: Kreb, Joseph
Abstract:: Spectroscopic ellipsometry (SE) is used to characterize amorphous and crystalline thin films of TiO2. Amorphous precursor films of TiO2 are deposited by radio frequency magnetron sputtering on fused silica and silicon substrates. Annealing the amorphous precursor films induces them to crystallize into either pure or mixed phases of the three...

Utilizing economic indicators in a machine learning platform to create an interdisciplinary forecasting framework for natural resource management and policy planning

Creator:: Polinsky, Joseph Mark
Abstract:: Abstract: Resource managers and policy face challenges in forecasting the demand for natural resources replenishment (where possible) of natural resources due to changes in human lifestyle, population change and economic development. The year 2020 demonstrated this challenge on several fronts, including the realm of natural resources. Additionally, much competition for...

Development of Computational, Visualization, and Molecular Tools for Fungal and Oomycete Community Ecology

Creator:: Foster, Zachary Stephen Longiaru
Abstract:: Oomycetes are an important group of organisms with a variety of ecological roles similar to fungi. Although many are well-studied plant pathogens known for their devastating effects on agricultural systems, most are little-studied saprobes and parasites of plants and animals in nearly every ecosystem on earth. The advent of affordable...

Inferring Patterns and Processes of Emergence in Clonal Phytophthora Epidemics using Population Genomic Approaches

Creator:: Cauldron, Nicholas C.
Abstract:: Oomycete and fungal pathogens threaten food, fiber, and forests around the world. With climate change, these pathogens are expected to emerge more frequently. Evolution can facilitate their emergence through mechanisms such as mutations that change or expand host range. Characterizing evolutionary mechanisms in plant pathogens will contribute to our ability...

New species and new combinations in the genus Paraisaria (Hypocreales, Ophiocordycipitaceae) from the U.S.A., supported by polyphasic analysis

Creator:: Tehan, Richard M., Dooley, Connor B., Barge, Edward G., McPhail, Kerry L., and Spatafora, Joseph W.
Abstract:: Molecular phylogenetic and chemical analyses, and morphological characterization of collections of North American Paraisaria specimens support the description of two new species and two new combinations for known species. P. cascadensis sp. nov. is a pathogen of Cyphoderris (Orthoptera) from the Pacific Northwest USA and P. pseudoheteropoda sp. nov. is...

Cyclosporine Biosynthesis in Tolypocladium inflatum Benefits Fungal Adaptation to the Environment

Creator:: Yang, Xiuqing, Feng, Peng, Yin, Ying, Bushley, Kathryn, Spatafora, Joseph W., and Wang, Chengshu
Abstract:: The cycloundecapeptide cyclosporin A (CsA) was first isolated from the insect-pathogenic fungus Tolypocladium inflatum for its antifungal activity and later developed as an immunosuppressant drug. However, the full biosynthetic mechanism of CsA remains unknown and has puzzled researchers for decades. In this study, the biosynthetic gene cluster is suggested to...
