The work of engineering education researchers has resulted in the development of research-based instructional strategies (RBISs) aimed at providing educators with means to increase student learning. Research has shown that there is a disconnect between the development of RBISs and their use by educators. Means to make new practices more...
Student engagement in a course plays a vital role in a student’s ability to process and construct knowledge. Student engagement research has investigated how students engage in and out of the classroom on a macro scale, through observation and survey data collection of large student populations, which lack focus on...
Ambient-pressure X-ray photoelectron spectroscopy has been used to study the initial stages of dry thermal oxidation of Si₀.₆₀Ge₀.₄₀(001) grown epitaxially on Si(001). Chemical state resolved AP-XPS was performed at temperatures up to 300 ˚C and O₂ pressures up to 1 mbar. Comparisons were made to Si(001) and Ge(001). The Si...
The forests in the Pacific Northwest are highly productive for timber and are a major factor in the economies of the region. The Pacific Northwest is the leading producer of lumber and plywood in the country. The use of harvester-forwarder cut-to-length harvest systems as a method for timber harvests in...
Low temperature combustion (LTC) engines offer improved efficiency and reduced emissions over traditional gasoline spark-ignited and diesel compression-ignition engines. The ability to produce fuels optimized for LTC engines could help increase efficiency and therefore improve fuel economy, insomuch that Federal fuel economy standards could be met. Currently, a fuel performance...
This work introduces a new methodology to design transportation fuels offering improved efficiency and reduced emissions, aimed to complement both traditional and emerging engine technologies. Many of these emerging technologies are centered around exploiting low temperature combustion (LTC) strategies that offer improved efficiency and reduced emissions. However, a standardized fuel...
Materials with a strong spin Hall effect and Rashba-Edelstein effect have the potential to improve the efficiency of solid-state magnetic memory technologies and other magnetic logic devices. Heavy metals have been identified as having these properties, including the beta crystal phase of tungsten. In this work, we determine the strength...
The droplet formation process in the vicinity of the nozzle exit and the behavior of a spreading droplet during impingement on a smooth glass surface were studied. Two nozzle geometries were tested. The first case was a stiff stainless steel nozzle plate 0.787 mm thick. The second case was a...
Marine geophysical data from the continental margin of Baja
California and the Gulf of California, and geological and geophysical
data from the Baja California Peninsula and mainland Mexico, outline
the major geologic and tectonic features of the Baja California
Peninsula and the surrounding areas from 24.5° N. Lat. to 27.5°...
In 1976-77 and 2010, Oregon State University (OSU) excavated portions of the enlisted men’s barracks and privy at Fort Hoskins, a Civil War-era fort. In operation from 1856 to 1865, this fort served as part of a security network to protect and monitor the recently created Coast Indian Reservation. The...
