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....
Drones are being used increasingly in the transportation sector for roadside applications such as surveying, structural inspection, and traffic monitoring, which raises distraction concerns for drivers. This study examines the visual attention of a group of Oregon drivers to determine drones’ potential as distracting roadside elements. Eye tracking data was...
While seemingly harmless, stereotypes can play a significant role in prejudice and discrimination. In two studies, we examined stereotypes of Asian American women and how they may vary with different clothing types. We used a mixed factorial design with a sample of college students from a U.S. university. In the...
This thesis aims to address barriers that K-5 educators face when implementing environmental education in classrooms. An in-depth study of the history of environmental education in the United States identifies primary barriers and issues. Focusing specifically on garden education programs, six lesson plans for K-5 were created to address the...
Myxozoans are microscopic parasites, related to corals and jellyfish. Most Myxozoa probably have two-host lifecycles that require a vertebrate (typically fish) and invertebrate (annelid or bryozoan). However no life cycle is known from the Sphaerospora lineage.
I hypothesized that the life cycle of Sphaerospora elegans, a myxozoan parasite of three-spined...
The purpose of this research is to provide a simple fabrication method for zinc oxide and antimony sulfide based thin film solar cells. Both a ZnO nanorod electron conducting structure and a stibnite absorber show promise in a solar cell. Initial attempts at using only ZnO and Sb2S3, however, resulted...
This thesis examines the dielectric properties of two systems based on the perovskite materials
barium titanate and strontium titanate. A solid solution was created starting with these base
materials and then adding varying amounts of bismuth-zinc titanate and sodium niobate. These
compositions were calcined and sintered at temperatures determined to...
Neurofibromatosis type 2 (NF2) is a genetic disorder caused by the inactivation of the
merlin tumor suppressor gene. NF2 patients develop bilateral vestibular schwannomas
(VS) and other nervous system tumors with no effective drug treatment option. In
pathological conditions, including NF2, production of the oxidant peroxynitrite leads to
protein tyrosine...
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...
Dissolved organic carbon (DOC) flux is an important mechanism to convey soil carbon (C) from aboveground organic debris (litter) to deeper soil horizons and can influence the formation of stable soil organic carbon (SOC) compounds. Aboveground litter quantity and quality was manipulated for 20-years in an old-growth Douglas fir forest...
