Microbial activity within elevated CO2 and oxygen depleted environments changes with
density driven stratification overturn in the seasonally anoxic region of Devil’s Hole,
Bermuda. The temperature gradient developed during the summer months creates a
natural laboratory to study bacterial and virus population density and microbial
community dynamics in the anoxic...
The spring bloom is a key oceanic phenomenon in the Northern Gulf of Alaska (NGA), where it supports the regional ecosystem, fisheries, and CO2 sequestration. Despite its significance, mechanisms that trigger NGA blooms are still debated, largely due to a lack of sufficient data from late winter through spring. New...
The development of a continuous and reliable cooling method for computer chips is an evolving subject requiring continuous research in both computer science and thermal management. Two-dye laser induced fluorescence (LIF) provides a minimally invasive way to investigate electronics cooling fluid behavior. Dielectric fluids are of particular interest as they...
Transcriptome gene expression studies of sperm RNA have been utilized in a variety of different species to investigate causes of male infertility. Previous research investigators have optimized cell separation and RNA isolation techniques for each species of interest. To date, no study has been completed for dogs. The objective of...
The dense Corvallis array deployed in January of 2022 aided in the high-resolution study of local geology. This array was made of 177 SmartSolo 3-component 5 Hz geophones around Corvallis, with a 93 geophone profile going west towards Bald Hill for approximately 5 km at an average of 64 m...
Spotted-wing drosophila (SWD, Drosophila suzukii) is an invasive fruit fly species native of Southeast Asia. In vineyards, SWD lays eggs in damaged and intact fruit of the most soft-skinned varieties, and feeds on damaged fruits during the harvest period. Feeding and oviposition activities increase the likelihood of vectoring spoilage bacteria,...
High purity isopropyl alcohol (IPA) is utilized in silicon wafer manufacturing in cleaning and drying processes. With the ever-decreasing die size, there is an increased need for even higher purity chemicals. This process was designed to further purify a 250,000 lbs/month stream high purity isopropyl alcohol stream for use in...
Milk collected from individual cows (n= 31) was centrifuged to equalize fat composition and was tested during chymosin-induced coagulation to compare the influences of somatic cell level, breed, parity, protein composition, and lactation stage on coagulation rate. Coagulation rate was determined using diffuse reflectance. Pearson correlation coefficients were calculated for...
An understanding of oppression and privilege would improve engineering climates and encourage individuals with marginalized identities to stay engaged in engineering spaces. Currently there are quantitative tools to assess cultural competencies, but none that measure understandings of power relationships. This project aims to create a qualitative assessment instrument to measure...
As juvenile salmon migrate from freshwater into saltwater, physiological changes must occur to allow fish to osmoregulate in the marine environment. Juvenile spring Chinook salmon migrate to the ocean at different time periods, most notably in the fall (August – November; i.e. fall smolts) and spring (February – May; i.e....
