Ocean acidification is a global, long-term problem whose ultimate solution requires carbon dioxide reduction at a scope and scale that will take decades to accomplish successfully. Until that is achieved, feasible and locally relevant adaptation and mitigation measures are needed. To help to prioritize societal responses to ocean acidification, we...
OBJECTIVE: In this study, we examined how effectively
people can monitor new stimuli on a peripheral display
while carrying out judgments on an adjacent central display.
BACKGROUND: Improved situation awareness is critical
for improved operator performance in aviation and many
other domains. Given the limited extent of foveal processing,
acquiring...
This study demonstrated at the pilot-scale (50 kg) use of Douglas-fir forest harvest residue, an underutilized
forest biomass, for the production of high titer and high yield bioethanol using sulfite chemistry
without solid–liquor separation and detoxification. Sulfite Pretreatment to Overcome the Recalcitrance
of Lignocelluloses (SPORL) was directly applied to the...
Energy consumption has become a significant concern for cloud service providers due to financial as well as environmental factors. As a result, cloud service providers are seeking innovative ways that allow them to reduce the amount of energy that their data centers consume. They are calling for the development of...
This study presents a methods evaluation and intercalibration of active fluorescence-based measurements of the quantum yield (ϕ'ₚₛᵢᵢ) and absorption coefficient (aₚₛᵢᵢ) of photosystem II (PSII) photochemistry. Measurements of ϕ'ₚₛᵢᵢ, aₚₛᵢᵢ, and irradiance (E) can be scaled to derive photosynthetic electron transport rates (Pₑ), the process that fuels phytoplankton carbon fixation...
The recent multistate outbreak of
a multidrug-resistant (MDR) Salmonella Heidelberg
strain from commercial poultry production highlights
the need to better understand the reservoirs of these
zoonotic pathogens within the commercial poultry production
and processing environment. As part of a larger
study looking at temporal changes in microbial communities
within the...
Mercury (Hg) is a globally distributed environmental
contaminant with a variety of deleterious effects
in fish, wildlife, and humans. Breeding songbirds may be
useful sentinels for Hg across diverse habitats because they
can be effectively sampled, have well-defined and small
territories, and can integrate pollutant exposure over time
and space....
The Oregon education system at both the K-12 and Postsecondary level is strained for resources, with funding at levels far below the national average. This is due, in large part, to the small percentage of state taxes that are used to fund education. Public support for additional revenue for schools...
The present work characterizes the time-space scales of variability and forcing dependencies of a unique 26 year record of daily to hourly shoreline data from a steep beach at Duck, North Carolina. Shoreline positions over a 1500 m alongshore span were estimated using a new algorithm called ASLIM based on...
We examine cumulative changes in investor sentiment and find that these changes relate to extended periods of increasing overvaluation, followed by price corrections. The relation between sentiment and returns is path dependent — short-term increases in sentiment precede strong positive returns, while prolonged periods of increasing sentiment precede negative returns....
Ocean acidification results in co-varying inorganic carbon system variables. Of these, an explicit focus on pH and organismal acid-base regulation in has failed to distinguish the mechanism of failure in highly sensitive bivalve larvae. With unique chemical manipulations of seawater we show definitively that larval bivalve shell development and growth...
Although surfers have high incidental exposure to marine waters, no studies have investigated if surfer risk behaviors (such as surfing during advisories, near an outfall, during a rain event, or use of personal protective equipment) increase or decrease the risk of acquiring waterborne illnesses. We used a web-based survey to...
Building Information Modeling (BIM) provides automatic detection of design-related errors by issuing warning messages for potential problems related to model elements. However, if not properly managed, the otherwise useful warning feature of BIM can significantly reduce the speed of model processing and increase the size of models. As the first...
Chordomas are uncommon neoplasms arising from notochord remnants, most commonly
occurring in the axial skeleton. Extraskeletal soft tissue chordomas are rare primary tumors, and
primary intestinal chordomas have not been reported. Herein we report 24 cases of spontaneous
primary intestinal chordomas in zebrafish, as well as 9 spontaneous vertebral chordomas....
SUMMARY - REASONS FOR PERFORMING STUDY: Exertional rhabdomyolysis (ER) is a reported syndrome in competing endurance horses; however the prevalence and cause of ER in this population has not been defined.
OBJECTIVES: To determine the prevalence of ER in a sample of endurance racing horses, and to investigate factors, including...
BACKGROUND: In the prenatal period, women can have sustained contact with nurses and other clinicians, forming relationships that are likely to be health enhancing both for the woman and her unborn child. Yet first trimester care use in Oregon dropped noticeably over the past decade. In comparison with Washington State,...
Changes in soil C and N pools following wildfire are quite varied, but there is little understanding of the causes of the variation. We examined how the legacies of prefire ecosystem structure may explain the variation in soil trajectories during the first decade following wildfire. Five years prior to wildfire...
