Outdoor School for All! Student Outcomes in Oregon is an ongoing evaluation project of outdoor schools throughout Oregon. The intent of this project is to build understanding and knowledge about the outcomes of outdoor school programming and support program improvement. We built an evaluation system based on legislative requirements, ongoing...
White rot, caused by Sclerotium cepivorum, is a serious disease that causes significant yield losses in Allium production. The pathogen persists in soil as sclerotia, which germinate in response to sulfur compounds in Allium root exudates. This study was aimed at investigating the potential of early-terminated Allium bait crops to...
Zinc is an important micronutrient involved in many cellular processes, including those part of immune function; however, about 15% of the US population is at risk for marginal zinc deficiency. This can lead to immune system complications including the generation of inflammatory cytokines. Aging is another factor that worsens the...
In recent years, non-renewable and non-biodegradable plastic packaging forms the majority of landfilled waste. These products, mainly made from Polyethylene Tetraphlatate (PET) and other polyolefins, have excellent durability and barrier properties, but take hundreds of years to degrade.
Much focus has been put on developing environmentally friendly alternatives to polyolefins...
2020 and 2021 brought the first reported outbreaks of salmonellosis epidemiologically linked to dry bulb onions in the United States. Outbreak investigations were not able to implicate a specific source of the contamination but speculated that contaminated water was a significant contributor. The Produce Safety Rule established minimum standards for...
In recent years, unoccupied aircraft systems (UAS) have become increasingly affordable and straightforward to incorporate in monitoring applications of forested ecosystems. This shift has facilitated interest in using these tools to monitor aspects of forest ecosystems including vegetation health, forest structure and composition, and potential habitat provided by these systems....
This paper examines the invasion of exotic wilding conifers on the native tussock grasslands of Aotearoa New Zealand. The investigation includes two studies and aims to better understand the structure of Pinus contorta seeds across tree crown positions and the viability rates of P. contorta seeds produced during a trees...
The ferromagnetic resonance (FMR) phenomenon serves as a sensitive probe of the effective internal fields in a magnetic material. FMR spectroscopy has consequently become a well-established technique, extensively employed in assessing material properties such as magnetic anisotropy, Landé g-factor, damping parameter, and the magnetoelastic constants of magnetic materials. Determining these...
As the development, processing, and manufacturing of plastic has improved over the years, so has our amount of plastic waste. Currently, only approximately 9% of post-consumer plastics get recycled. The other 91% is buried in landfills, burned, ends up in the ocean, or is accumulating in communities without access to...
