Ocean acidification (OA) is the result of increasing concentrations of anthropogenic carbon dioxide (CO₂) emissions, leading to a suite of alterations to specific parameters of ocean chemistry, which can negatively impact many marine organisms and ecosystems. Understanding how to measure and monitor the chemistry of OA will require specialized education...
Anserine and carnosine are water-soluble dipeptides that have antioxidant
properties and are found in the skeletal muscle of mammals and fishes. These
dipeptides are removed through the washing process in surimi production. The
objective of this research was to determine the concentration of anserine and
carnosine in surimi wash water...
Ocean observing groups are currently making efforts to work with well-defined end-user groups, like boaters and fishermen, to provide meaningful and effective real-time data (RTD) products and visualizations. However, providing meaningful data products for undefined groups such as the general public is not straightforward. In Oregon, several industry, science, and...
In recent years, there has been renewed interest in black raspberry (Rubus
occidentalis L.) breeding. This has been spurred, in part, by an increase in black
raspberry consumption due to studies that have shown them to be particularly high in
anthocyanin content indicating high levels of antioxidants. Present cultivars are...
We report a novel cancer-targeted nanomedicine platform for imaging and prospect for future treatment of unresected ovarian cancer tumors by intraoperative multimodal phototherapy. To develop the required theranostic system, novel low-oxygen graphene nanosheets were chemically modified with polypropylenimine dendrimers loaded with phthalocyanine (Pc) as a photosensitizer. Such a molecular design...
While real-time hybrid simulation has been utilized for structures subjected to seismic events for decades, its use in fluid-structure interaction problems is still a novel endeavor. Gathering data for cascading seismic and tsunami events is difficult due to space constraints in existing experimental facilities, complications regarding the application of scaling...
All existing sea otter, Enhydra lutris, populations have suffered at least one historic population bottleneck stemming from the fur trade extirpations of the eighteenth and nineteenth centuries. We examined genetic variation, gene flow, and population structure at five microsatellite loci in samples from five pre-fur trade populations throughout the sea...
The capabilities of modern three-dimensional (3D) capture technology such as laser scanning and image-based 3D reconstruction are well suited to enhance the practice and research of civil engineering. However, given the often-overwhelming focus placed on the incredible capabilities of these tools and techniques, it is important to investigate the limitations...
Background: Transcriptome sequencing and assembly represent a great resource for the study of non-model species, and many metrics have been used to evaluate and compare these assemblies. Unfortunately, it is still unclear which of these metrics accurately reflect assembly quality.
Results: We simulated sequencing transcripts of Drosophila melanogaster. By assembling...
The purpose of this grounded theory mixed methods study is to understand how new scuba dive students are creating meaning of their relationship to the marine environment and how that might be shaped by dive training and dive experiences. Eighty-one scuba dive students enrolled in a standardized entry-level dive course...
Community colleges today are experiencing monumental shifts in their operating
environments. Some of these changes are known, but many of them are not. They
include shifts in curriculum, funding, and societal expectation to name a few. Through
the constructs of high quality work environment and organizational fluidity theory, this
research...
STEM education is delivered to K12 audiences by Pre-college Programs across the nation, many of which serve underrepresented and underserved students as part of their core missions. While there is robust attention to STEM curriculum development and college connection events in such programs, few have social-cultural aspects of learning as...
In 2021, Oregon’s legislature passed House Bill 2021 with relative ease. House Bill 2021 is a mandate for the state’s two largest utilities to reduce carbon emissions from electricity generation on a decreasing scale, reaching 100% below baseline levels by 2040. This ambitious piece of legislation, meant to reduce the...

The near physical environment is believed to be an integral component in creating quality learning and classroom environments for young children. Free-choice play periods during preschool daily curriculums are a widespread component of preschool early childhood education. Research has demonstrated that the presence of houseplants may be a contributor to...
Strawberry is one of four crops included in the USDA-NIFA Specialty Crop Research Initiative-funded RosBREED project along with apple, peach, and cherry. Phenotyping strawberry for specific horticultural and commercial traits is important to identify associations with genotypic marker(s). This process is the first step in translating genomic knowledge into enhanced...
Strawberry is economically the most important berry crop grown worldwide and breeders are continuously striving to develop improved cultivars. So far, marker assisted breeding (MAB) in strawberry has been limited to the private sector. However, loci controlling some traits of economic importance such as perpetual flowering (PF) and soluble solids...
Since the decline of salmonid populations in the Pacific Northwest, supplementation programs have become frequently implemented by hatcheries as a way to protect and conserve wild stock. However, hatchery-reared fish have lower fitness than wild fish which is likely due to adaptation to the hatchery environment, i.e., domestication selection. Fish...
Climate change poses known and unknown risks for coastal communities and also challenges for university faculty and local government staff who communicate about climate sciences. Conceived as a way to move beyond traditional models of science communication, this project involved public and private decision makers in specific at-risk communities in...
