The ability of the resin to deform plastically can be an
important factor when considering the mechanical properties of particleboard.
Between resin droplets there exists an unbonded region
that forms the surface for a crack. When particleboard is deformed
stress concentrations develop at the crack tips in the voids. A...
Past research has implied that differences in blender performance
between commercial and laboratory particleboard blenders
may not be attributed to resin distribution between screen fractions,
as is commonly believed in the industry today, but to which particles
within a screen fraction have resin and which do note
To test this,...
Reducing the cover of non-native species is one of the challenges of ecosystem restoration. The goal of this study is to identify native species traits that will increase native species cover and reduce non-native species cover in the first growing season at upland and wetland prairie restoration sites. Native and...
Prior to European settlement, native prairie dominated the landscape of the
Willamette Valley. Today, due to urbanization, agriculture, and the cessation of
burning, only isolated remnants of these grasslands still exist. In response to
conservation concerns, there has been a move to restore the remaining prairies in the
Willamette Valley,...
This study aimed to determine the efficacy of baking to reduce bacterial populations (an unknown contaminant or Salmonella) in cookie dough. Baking conditions (time and temperature parameters) were selected based on conditions commonly used in industry. The first study (Chapter 2), “Baking as Validation for Control of Coliform Counts in...
Southwest Oregon presents an environment of hot dry summers, cool moist winters, and rocky, shallow soils. The establishment of conifer plantations in this region presents challenging problems for initial seedling survival and subsequent growth. Three areas of concern include early conifer growth after seedling establishment, growth of competing hardwoods within...
This study examined the reading-writing relationship for
99 exclusively international students, and used narrative,
and timed and untimed expository writing samples. The reading
comprehension test was the Degrees of Reading Power (DRP), a
test appropriate for use with English as a second language
(ESL) learners.
Results of the study indicated...
The Experimental Advanced Airborne Research Lidar ‐ B (EAARL‐B), which was built and deployed by the U.S. Geological Survey (USGS) in 2014, is a novel topographic‐bathymetric lidar system. While retaining a number of features that were pioneered in the original National Aeronautics and Space Administration (NASA) EAARL system (e.g., low...
