Evaluation of ECOSTRESS products for estimation of leaf and grape water stress for Southern Oregon vineyards

Creator:: Swafford Steffensen, Collen
Abstract:: Accurate estimation of water stress in vineyards could prove vital for optimizing irrigation and grape quality in a changing climate. The ECOsystem Spaceborne Thermal Radiometer Experiment on the Space Station (ECOSTRESS) offers potential to remotely sense vineyard water stress but lacks validation against in-field measurements in vineyards. In this study,...

Toward an Optimal Working Distance for Hyperspectral Imaging of Wood

Creator:: Jayawickrama, Michelle T.
Abstract:: The forest products industry relies on the production of high-quality wood to satisfy consumer requirements. Improving wood quality requires an effective and inexpensive technique for measuring critical properties such as density and microfibril angle. An emerging technology known as near-infrared hyperspectral imaging (NIR HSI) essentially captures surface images of samples...

Stability of Super Folder Green Fluorescent Protein Under Varying Organic Solvent and Temperature Conditions

Creator:: Ho, Lylan
Abstract:: Obtaining high-resolution structures of biological macromolecules has become one of the biggest challenges in the scientific world. Dr. Wei Kong’s lab is currently working to overcome the limitations of current structure resolution techniques, such as x-ray crystallography and nuclear magnetic resonance spectroscopy. Kong’s group hopes to develop a new protein...

Understanding local perceptions of an economy in transition : Tourism in South Caicos, TCI

Creator:: Wiegand, Jenna L.
Abstract:: Tourism presents a significant challenge for island economies in the Global South attempting to improve local standards of living. Due to limited resources and often low education levels of island residents, tourism development frequently becomes a tool for foreign investors to profit while local people continue to work low-income jobs....

The Art and Science of Woodturning : A Year in Exploration

Creator:: Andersen, Claudia C.
Abstract:: Woodturner, artist, and scientist, Claudia Andersen, describes various anatomical features of wood, from the differences between softwoods and hardwoods to the various types of spalting. Over the past year, they have learned and developed their skills in woodturning. In this project, they accompany one woodturned piece with a description of...

Freshwater prokaryotic and eukaryotic diversity of the Oregon Willamette River basin

Creator:: Hoyle, Marilee C.
Abstract:: The wellbeing of the Willamette basin in Oregon depends on the river ecosystem’s microbial communities, which control primary production and the biological processing of nutrients, pollutants, and organic matter. Yet, only a few studies have investigated the diversity of the microbial communities of the Willamette basin. This paper examines how...

Isotopic Analysis of Diet Specificity in the Chisel-toothed Kangaroo Rat, Dipodomys microps

Creator:: Guerre, Megan E.
Abstract:: Rapid changes in global climate have put many species at risk, particularly niche specialists. The Chisel-toothed kangaroo rat, Dipodomys microps, is thought to specialize on the desert shrub Atriplex confertifolia. Because of this close relationship, D. microps was presumed to have tracked the shrub as its distribution shifted south during...

How competitive are iconic competitors? Testing resource partitioning in Great Basin chipmunks

Creator:: Ormand, Elora J.
Abstract:: Competitive exclusion is a key concept in ecology describing the exclusion of one species by another from access to a limited resource. Competitive interactions between chipmunk species in the Great Basin, documented by James Brown in 1970, are often used as a textbook example of competitive exclusion. Whether competitive interactions...

Physics Students' Mindsets and Their Impact on Learning and Perceived Satisfaction

Creator:: Le, Tiffany
Abstract:: Characterizing a mindset landscape within the physics classroom is crucial to portray the variation and context of mindset in the classroom. This paper will be looking at students enrolled in Oregon State University’s PH20x series, which is a series of three algebra-based introductory physics courses. This project is an exploratory...

Analysis of Alternative Donor Breast Milk Pasteurization Techniques and Their Impact on Bile Salt-Stimulated Lipase Activity

Creator:: Victor, Ashley F.
Abstract:: While breast milk is considered the best nourishment for newborns, they have a lowered ability to digest the fat rich liquid due to decreased lipase secretion for the first few months after birth. To offset this, breast milk itself contains Bile Salt-Stimulated Lipase (BSSL) which significantly heightens fat digestion ability....
