Heat flux measurements of radiation emissions from turbulent premixed flames diluted with N 2 and CO 2 were taken to identify sensitivities of radiation heat loss to diluent fraction and species. This work is motivated by the desire to better characterise radiant heat transfer in the presence of combustion products,...
Skin condition assessment of wildlife can provide insight into individual and population health. Yet, logistics can limit skin condition assessment of large whales. We developed a standardized, quantitative protocol using photographs to assess skin condition of blue whales in New Zealand, and demonstrate the value gained by testing hypotheses, documenting...
Chiropractic treatment is used to reduce stiffness and pain. While more thoroughly studied in humans, it has been shown to be effective in horses, but relatively little evidence exists to quantify the benefits. To address this shortcoming, four methods were used to assess the effects of chiropractic treatment in horses...
Under the Paris Agreement, parties submitted documents outlining their commitments to climate change mitigation and adaptation, called Nationally Determined Contributions (NDCs), which are set to be updated to increase ambition by 2020. Costa Rica and México are known for their significant national actions on climate change, so comparing these two...
This thesis examines the multi-faceted threat Iran poses to the stability of the Middle Eastern region, to U.S. geopolitical interests and to the furthering of democratic principles from a realist perspective. Iran’s failure to negotiate a nuclear accord in good faith coupled with its continued militant role in regional affairs...
With the rise of resistant bacterial pathogens, currently prescribed antibiotics are rendered useless. In recent years, marine natural products (MNPs) have emerged as novel sources for drug leads. The ocean is a complex environment where marine animals cohabitate with many, and sometimes harmful microorganisms and viruses, but resist infections. Developed...
Using X-ray computed tomography (CT) scanning to characterize the physical characteristics of soil and sediment cores allows scientists to observe and analyze stratigraphy without destroying the integrity of different layers. Microbiologists often work with geologists to characterize the microbial communities in such cores; however, X-rays are known to be destructive...
The relationship between a parent and child in the first years of life have a significant effect on the development of children. Parenting education can be a valuable resource for learning evidence-based parenting strategies, but access to parenting education is limited in many states. Oregon has a unique statewide system...
Oregon State laboratories are responsible for a significant portion of the university’s overall resource and energy consumption, and therefore minimizing waste in a sustainable way should be a top priority for the university while aiming for carbon neutrality by 2025. This study addresses major factors that should be considered when...
Electrochemical sensing provides a quantitative alternative to colorimetric reactions within paper-based devices. The paper-based devices were fabricated by screen printing the conductive and reference inks onto porous substrates that were evaluated using cyclic voltammetry. Devices were evaluated based on the magnitude of the average anodic peak height, which correlates with...
Stream light availability is an important factor influencing aquatic food webs. In forested headwaters, stream algal production is often highly light-limited, so an increase in light enhances benthic algal growth, which in turn increases food availability for primary consumers in the stream. In forested headwater streams, light availability is almost...
This research examined the potential for using peanut husk as a fiber alternative to wood in the production of melamine-formaldehyde (MF) particleboard. MF resin was used to produce panels with one, three, six, nine or 12 percent resin contents. Modulus of Rupture (MOR), Modulus of Elasticity (MOE), Internal Bond (IB)...
There is no shortage of challenges in modern science, including the task of obtaining high resolution images of biomolecular structures, such as proteins. Current atomic-resolution structure determination methods include x-ray crystallography and nuclear magnetic resonance (NMR), which present issues like protein crystallization and loss of resolution with increasing size. Dr....
Hypoproteinemia secondary to gastrointestinal disease in horses has traditionally been treated with the administration of colloids such as equine plasma or hetastarch. While plasma transfusion is common, evidence-based guidelines for its use in hypoproteinemic horses are lacking. This study involved prospective and retrospective components that aimed to weigh the efficacy...
This study sought to understand the commonality of vaccine misconceptions among college students and where individuals feel they are obtaining their vaccine information. An IRB approved survey was used to collect 126 responses from Oregon State University students. Individuals, on average, correctly answered only 54.10% of the statements based on...
Research poster for Summer Undergraduate Research Symposium 2019. Research was conducted with CURE funding in the Perez lab studying cellular senescence in the PS19 mouse model.
A 3-minute lightning talk was given by Victoria Keenan at the 2019 Summer Undergraduate Research Symposium on her role as a researcher for the Community Doula Project in Linn, Benton, and Lincoln counties. The presentation provided an insight into the emergent themes identified from the ongoing semi-structured, open-ended qualitative interviews...
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...
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...
Sablefish is a highly sought after seafood delicacy for which aquaculture of this species has recently been developed. By understanding the immunological functions in sablefish, our goal was to develop a mammalian fluorescent bioparticle assay that can viably analyze the efficiency of phagocytosis, an important function of the immune system....
