As one of database types, CSV type database is widely used by many people because the type serves various useful purposes for business, engineering, and environment. However, the CSV type database could be complicated to understand because it is usually written on spreadsheet like Microsoft Excel format. Therefore, data visualization...
The shallow aquifer in Southern Willamette Valley (SWV) has high levels of nitrate, and we are exploring the time trends in nitrate, and the hydrologic and land management factors that contribute to this problem. Nitrogen (N) inputs to farmland from fertilizer is thought to be the primary source of nitrogen...
The California Current Ecosystem (CCE) is a dynamic marine ecosystem from which many socioeconomically important fisheries species are harvested. In this thesis, a genotyping-by-sequencing (GBS) approach was used to examine genomic variation in an early life stage of the Dungeness crab (Cancer magister), which constitutes the most valuable single-species commercial...
Succinate dehydrogenase (Sdh) inhibitor fungicides, such as boscalid, are effective for the management of gray mold caused by the fungal pathogen Botrytis cinerea. Unfortunately, resistance to boscalid was common among isolates of the pathogen from small fruits grown in Oregon. Boscalid-resistance is commonly associated with mutations in Sdh, especially in...
The Columbia River Basin historically supported abundant populations of Pacific salmon (Oncorhynchus spp.) but, largely due to anthropogenic influence, many populations are now listed as threatened or endangered under the U.S. Endangered Species Act. Habitat restoration efforts have been a critical component of salmon recovery plans. However, although the importance...
While robotic systems may have once been relegated to structured environments and automation style tasks, in recent years these boundaries have begun to erode. As robots begin to operate in largely unstructured environments, it becomes more difficult for them to effectively interpret their surroundings. As sensor technology improves, the amount...
Contaminants in stormwater such as heavy metals, PFASs, PCBs, and PAHs are an issue for public infrastructure and remediation practices. Biochar, granular activated carbon (GAC), OGSIR soil, and commercial adsorbent materials have been evaluated with the heavy metals Cu2+ and Zn2+. Copper and zinc as stormwater contaminants were treated with...
The modeling and analysis of laboratory-generated nonlinear intermediate- to deep-water wave fields, using existing wavemaker theories and analysis tools, is one of the most challenging tasks in ocean science and engineering. On one hand, harmonics function (sine and cosine) -based wavemaker theories result in an inherent (linear) instability of the...
Approximately one in six children in the United States has a developmental disability (CDC, 2018). Among a wide variety of interventions that have been developed to support the health, wellbeing, and development of youth with disabilities, Animal-Assisted Interventions (AAI) have become increasingly prevalent. Some AAI involve youth participating with their...
Harvesting energy from ambient sources can provide power autonomy to energy efficient electronics and sensors. The last decade has seen a multitude of ways to scavenge energy from various sources like solar, thermal, electromagnetic, electrostatic, piezo-electric and many more. Thermal energy from human body heat is ubiquitous and can be...
