Early theoretical models for the evolution of male-female
pairing were based largely on studies of birds. These models
assumed that biparental care of eggs and young was an
essential component of pairing. However, male-female pairing
is also a relatively common social system in coral-reef
fishes, and biparental care of young...
Arsenic contamination of groundwater is a global issue with national and local implications. Chronic exposure to arsenic in drinking water has been linked to both carcinogenic and non-carcinogenic health outcomes. The primary exposure route of inorganic arsenic is ingestion from drinking water due to natural contamination in groundwater from dissolution...
Degradation of lignin to simpler compounds is desirable for removing residual lignin during paper manufacture and accessing biomass carbohydrates for biofuel production, among other purposes. Lignin transformation using enzymes found in white rot fungi, some of nature's most efficient lignin-degrading organisms, offers a more environmentally benign, selective, and possibly less...
Despite the increase in information on the causes of foodborne disease, outbreaks continue to be a major preventable public health problem. Current food service establishment inspection programs, however, are not designed to assess the potential of risk for foodborne disease and do not focus prevention efforts where food service problems...
The project objective was to characterize stabilization of human recombinant Factor VIII (FVIII) with two surfactants, Pluronic® F-68 (F68) and Polysorbate 80 (PS80). Factor VIII is an essential blood clotting protein manufactured for treatment of Hemophilia A. Factor VIII has multiple hydrophobic regions requiring the use of amphiphilic molecules, such...
The purpose of this study was to identify the knowledge, attitudes, practices and barriers related to handwashing in the restaurant environment. The study was designed with multidimensional study tools to include: a focus group conversation with questions to food workers to develop an initial understanding of knowledge, practice and attitudes...
The purpose of this study was to examine Oregon State University students' self-reported knowledge, attitudes, and behavior about recycling. Students living in on-campus and off-campus organized living groups were mailed a four-page survey with questions about their recycling activities, their attitudes about recycling, their opinions of the effectiveness of the...
Benzene is a widespread urban pollutant and monitoring results show concentrations are particularly high in Portland, Oregon. Nationally, benzene air pollution is the largest contributor to total cancer risk from air pollutants. We used data from several data sets including: modeled benzene distribution at the census block group level from...
