Background: Barn Swallows (Hirundo rustica) breed almost exclusively in the Northern Hemisphere. However, since the early 1980's, a small disjunct breeding population has become established in eastern Argentina, presumably by birds previously derived from those breeding in North America. Currently, it is unknown where these individuals go following breeding and...
For the 2019 season, a new chassis layup was designed that is much stronger than in previous years, yet only slightly heavier. Compared to the baseline steel tube frame, the 2019 chassis has safety factors of about 110% for most zones. Also, a new impact attenuator was designed that absorbs...
In 2017, the Rohingya refugee crisis became recognized as the fastest growing and among the densest concentration of refugees in the world. The Rohingya have no legal citizenship in any country and are considered a stateless population. Pregnant persons and children are often more vulnerable to the effects of humanitarian...
On coral reefs, disturbances rarely occur in isolation. Global stressors such as increasing seawater temperature often coincide with local stressors like nutrient pollution. In the face of increasing anthropogenic stress, corals can function as environmental sentinels, although little is known about how multiple stressors interact to disrupt their associated bacterial...
Mental health professionals are dedicated to improving outcomes in therapy. Research over the past 50 years has shown psychotherapy to be effective in both improving the functioning of and diminishing the overall distress experienced by clients. Several factors have been constant predictors of outcome in therapy, including length of treatment,...
Background: All health systems struggle with unlimited needs for health care, yet limited resources with which to address them. Under national health insurance systems, policymakers must make explicit and potentially contested decisions around resource allocation. Policymakers have recognized the need to include public values in decisions of how to distributing...
Multi-phase flow in porous media includes many instances of subsurface flow. Three-phase flow in particular is important in situations of enhanced oil recovery, CO2 sequestration, and groundwater remediation. Many studies have been performed on how two fluid phases (oil/water or air/water) behave in porous media, but very few studies exist...
Five strains of the bean pathogen Pseudomonas syringae pv.
phaseolicola were analyzed for plasmid number, size, and relatedness.
Each strain contained one or two indigenous plasmids which ranged in
size from 6.8 to 151 kbp. BamHI and EcoRI restriction patterns revealed that total plasmid DNA from each strain had a...
This project explores the impact of land use decisions on dune processes at the
Oregon National Guard's Camp Rilea. located on the north coast of Oregon. It
used a combined analysis of historical and modern data sources to assess the
impact of land use practices. Historical sources including the journals...
