Spring grazing of annual ryegrass (Lolium multiflorum L.) seed
fields with sheep is a common practice in the Willamette Valley of
Oregon. However, the effect of grazing on seed yield in Oregon has
not previously been investigated. This experiment was designed to
determine the effects of duration of spring grazing...
The annual growth rate for the Corvallis-Benton County
area has traditionally been higher than the growth rate for the
State of Oregon. Corvallis is considered to be one of the most
densely settled communities in the state. Since 1972, Corvallis
has experienced a drastic decline in the number of housing...
Emissions of oxides of nitrogen from a small (15 kW) turbine generator burning high fuel bound nitrogen fuels were measured by a chemiluminescence method. Kerosene was used as the base fuel and pyridine was added to achieve different fuel bound nitrogen levels. Mixtures of 0.0%, 0.5%, and 1.0% (by weight)...
Conventional stainless steel - water and ceramic fabric composite water
heat pipes have been built and tested. The tests have been conducted to compare
the performance characteristics between conventional and fabric composite heat
pipe radiators for space nuclear power heat rejection systems. The fabric
composite concept combines a strong ceramic...
The purpose of this study was to compare the levels of bone
mineral density (BMD) of the whole body (WB) and proximal
femurs of physically active men with spinal cord injuries (SCI) to
nonactive men with spinal cord injuries. Also, the lean muscle
mass (LMM) of active men with SCI...
A lightweight carbon fiber reinforced polymer (CFRP) c-channel beam was previously designed using analytical theory and finite element analysis and subsequently manufactured through a pultrusion process. Physical testing revealed the prototype did not meet the bending and torsional stiffness of the beam model. An investigation revealed that the manufactured prototype...
The research presented here is a study to determine the effect of shear reinforcement corrosion on the shear capacity in conventionally reinforced concrete (CRC) bridge elements. A total of 14 CRC beams were tested using three stirrup spacings (8, 10, and 12-inch). Six of the beams included the influence of...
Most conventional approaches to rating turf color for different turf varieties grown
under similar conditions or for the same variety grown under different cultural conditions
employ a visual subjective rating. By digitizing remotely sensed images acquired by use
of a helium filled blimp and a Canon EOS camera, we were...
Phytophthora lateralis is the causal agent of cedar root rot, a fatal forest pathogen whose principal host is Chamaecyparis lawsoniana (Port-Orford-cedar), a predominantly riparian-restricted endemic tree species of ecological, economical, and cultural importance to coastal Oregon and California. Local scale distribution of P. lateralis is thought to be associated with...
