The Asphalt Pavement Analyzer (APA) device was used to characterize the impact of
various mix factors on the development of permanent deformation in dense-graded
mixes given a standard compactive effort. Factors included two aggregate sizes, three
VMA levels, two fines contents, three binder contents and four binder types. All

Oregon has thousands of culverts along mountainous roads that interact with perennial streams, intermittent streams, and intercepted subsurface flow from hill slopes. Culverts installed at stream crossings are designed to move water under the road and avoid failure of the fill. Similarly, ditch relief culverts transfer water through a road...
A set of 119 study trees was identified in a 65 year-old Douglas-fir stand after a thinning operation conducted seven years ago using pre-planned skid trails and groundbased machinery. Some of the trails were tilled using a winged subsoiler after this operation in order to alleviate the effect of compaction...
The purpose of this study is to determine factors that encourage second
generation Latina/os to obtain a community college education. A critical qualitative
ethnography focused on "Testimonio" was used in conducting this study. The key
findings were formulated around three critical research questions. In relation to each
research question, three...
Overall wood density is a complex trait resulting from the interaction of three components: average earlywood density, average latewood density, and latewood proportion. In order to better understand the genetic control of wood density in juvenile Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco), and to assess the utility of
information on its...
This thesis compares the implementation of additive manufactured suspension uprights against subtractive manufactured suspension uprights from concept generation, design, and validation through simulation. Additive manufactured suspension uprights were designed for Global Formula Racing’s 2023 electric vehicle. Utilizing Siemens NX, Nastran, Fusion 360, and Ansys Workbench both subtractive and additive manufactured...
Absorption of iron from foods has been reported to be inhibited by
various factors including some diet components. Fiber from different
sources has been observed to bind ferrous iron. This may be the reason
for iron deficiencies observed in populations that consume diets high in
non-digestible materials.
The effect of...
