This work investigates the effect of cation substitution on the properties of the lead-free, solid solution (Na₀.₅Bi₀.₅)TiO₃-BaTiO₃ (NBT-BT). Substitution into NBT-BT increases disorder and increases the relaxor ferroelectric properties. These relaxor ferroelectric materials show large piezoelectric strains that can be utilized in actuator applications. Ceramic samples were prepared using standard...
Fire severity is hypothesized as an important driver of bird responses to wildfire. For those species that typically respond negatively to increasing severity, Accessibility of high-severity burned forest may be dependent on the proximity of unburned or low-severity burned forest to meet all of the needs of breeding bird species...
The objective of this research was to determine if acupuncture can reduce bovine mammary inflammation. Lactating cows at the Oregon State University Dairy Research Center were selected based on Dairy Herd Improvement Association reports indicating a SCC >500,000 cells/mL. A California Mastitis Test (CMT) score of greater than one was...
Declining abundance of Chinook Salmon Oncorhynchus tshawytscha across the Pacific Northwest is an issue of
great concern ecologically, culturally, and economically. Growth during the first summer is vitally important for
juvenile Chinook Salmon, as it influences not only life history decisions (to smolt or not to smolt) but also subsequent...

The Covid-19 pandemic has affected everyone in the world to some degree through social isolation and a changing of the norms, including the number of deaths. However, no research has been done on how companion dogs in the United States have been affected by these societal changes. Research in Israel,...
Humpback whales (Megaptera novaeangliae) are a widely distributed baleen whale species, well known for their diverse acoustic behavior. On high-latitude foraging grounds, humpback whales produce a suite of non-song vocalizations (“calls”) in concert with foraging and social behavior. In this dissertation I investigated the role of calls in the acoustic...
There are over two million pet rabbits in the United States. Many rabbits are obtained as adults from pet stores and humane societies. Pet rabbit owners may elect to perform ovariohysterectomy (spay) surgeries on female rabbits to prevent unwanted pregnancies as well as to eliminate the possibility of reproductive disorders...
