The Oregon State University TRIGA® Reactor (OSTR) has a number of irradiation
facilities providing a wide range of neutron energies and fluxes. These facilities include a
pneumatic transfer tube, a rotating rack, a thermal column, four beam ports, in-core irradiation
tubes, a clyogenic gas transfer system and a large vault...
Mosses (Phylum Bryophyta) are widely considered to be among the most ancient groups of land plants (embryophytes) and they are the second most speciose embryophyte phylum with ~13,000 extant species. Despite their diversity and antiquity, mosses have a limited fossil record, which primarily consists of gametophytes entombed in Cenozoic amber....
The buildup of reactive oxygen species (ROS) and reactive nitrogen and oxygen species (RNS) is known as oxidative stress. Oxidative stress results in a wide variety of modification to biological macromolecules including nucleic acids, lipids, and proteins. For at least 30 years it has been known that high levels of...
Polyoxometalates are discrete anionic oxo clusters of the Group V and VI transition metals that can be conceptualized as molecular metal oxides. Because they are pairable with any alkali cation, a great deal of fundamental chemistry can be gleaned from their study, including solubility trends and insight into cation binding...
The Global Overturning Circulation (GOC) is a major component of the global climate system. Understanding its behavior is pertinent to our prediction of climate change in the future. The lack of long-term observations of GOC in the modern instrumental era necessitates studies of GOC using paleoceanographic records. Of great interest...
Testing of asphalt binders and asphalt-aggregate mixtures using dynamic
mechanical analysis is becoming popular with improvements in high-speed
computers, precision equipment, and computer software. Researchers are trying
to describe the behavior of asphalt binders and asphalt-aggregate mixtures in
terms of their time- and temperature-dependent linear viscoelastic behavior.
The objectives of...
Many conventionally reinforced concrete deck girder bridges (RCDG) and their intermediate supporting bent caps were designed during the Eisenhower interstate era of the 1950’s with the AASHO design equations at the time, which subsequently place higher demand on the concrete. The referenced components may exhibit diagonal cracking due to the...
Hexachlorophene (HCP; 2,2'-methylenebis-(3,4,6-trichlorophenol))
was developed as an antibacterial agent but was also found to induce
toxic effects in various tissues in animals and humans. Changes were
found in myelinated nerve fibers and cerebral white matter. Erythrocytes
are hemolysed in vitro. Oxidative phosphorylation is uncoupled
by HCP at concentrations less than...
Ocean testing of Wave Energy Converter (WEC) prototypes is necessary to facilitate commercial WEC development. The Ocean Sentinel Instrumentation Buoy, completed in August 2012, provides a stand-alone load for WEC prototypes during ocean testing. The first part of this work was to develop the power conversion and data acquisition equipment...
