The overall goal of this project was to design a wood frame shear wall that could withstand greater displacement before damage occurred to the Gypsum Wall Board (GWB). More specifically, the objectives of the study were: (1) to evaluate damage to the GWB in alternative shear wall designs at 1%,...
The primary objective of this research was to determine if native species within the genera Castilleja and Pedicularis are naturally infected by white pine blister rust (Cronartium ribicola) in whitebark pine ecosystems of the Oregon and Washington Cascade Range. Secondary objectives were to monitor the phenology of aecial and telial...
This thesis presents an approach to develop innovative methods for decontamination and surface protection applicable to naval nuclear ships and potentially, personnel, replacing antiquated techniques. To accomplish this goal, two products manufactured by CBI Polymers, LLC., DeconGel™ 1101 (1101) and a shampoo, DeconGel™ "prototype" (prototype), were tested.
The prototype was...
Seasonal wetlands in arid and semi-arid lands provide an important source of surface water in otherwise dry lands. Central Oregon's high desert, located in the Northern Great Basin (NGB) is dotted with hundreds of seasonal pools, locally called playas. The playas hold water or snow during parts of winter and...
This paper provides a measurement-based performance evaluation of the Optimized Link State Routing (OLSR) protocol. Two versions of OLSR, OLSR-ETX and OLSR-ETT, are implemented and evaluated on a mesh network that we built from off-the-shelf commercial components. OLSR-ETX uses the Expected Transmission Count (ETX) metric whereas, OLSR-ETT uses the Expected...
Digital Instrumentation and Detection is becoming the future of radiation detection and measurement. Computers are able to perform digitally what before would have taken an extensive array of analog equipment. The art of teaching radiation detection and measurement is following this same pattern of a shift from purely analog to...
Stripe rust (Puccinia striiformis f. sp. tritici) has been receiving
increased attention in the USA since the appearance of more virulent races
detected in the past decade. These races caused yield losses even in areas
where the disease previously was rarely detected. Host plant resistance is the
most cost effective...
This research sought to explore the implications of different tenure regimes for both
landscape-level ecological processes and the overall resilience of a social-ecological
system in Central Oregon. The purchase by an investor of former industrial timberlands
known as the Bull Springs tract raised the specter of dispersed residential development on...
Stand structure in headwater riparian areas of western Oregon is highly variable making quantification of structural attributes within these stands difficult. A reliable sampling design is important to characterize and monitor changes in stand structure over time. This study examined sixteen alternatives for sampling live conifers and six alternatives for...
Regression analysis was used to examine the effect of a change in agricultural prices on land use and conservation. The planted acreage for each of three crops – corn, soybeans, and spring wheat – was regressed on the expected prices of the three crops,
the input prices, and past land...
