To begin to understand freshwater seasonal floodplain fish communities in the context of human alteration of the physical system, species introductions and wetland restoration efforts, I studied fish assemblages in fifteen seasonal floodplain wetlands within four geographic regions (coastal, upper Columbia River estuary, Puget Sound and eastern Oregon/Washington) in the...
The gravel aquifer of the Oregon side of Walla Walla River Basin has a strong hydrologic connection to surface water through a series of springs, unlined irrigation canals, the Walla Walla River, numerous wells and, since 2004, artificial recharge to the shallow aquifer using infiltration basins. The finite element Integrated...
Downward flow opposing mixed convection conditions have been studied using the FLUENT CFD code. This work was comprised of two primary objectives. The first was to study core channel flow reversal susceptibility in the Gas Reactor Test Section (GRTS) at low flow conditions. The second objective was the development of...
Use of solid compensators is a very effective means of implementing IMRT on any linear accelerator. The standard practice has been IMRT delivery using accelerators equipped with multi-leaf collimators (MLC’s). Truth is the addition of MLC’s to an accelerator is quite expensive. Previous studies have shown solid compensators to have...
This study examined the relationships between business, education, and the economy, and specifically addressed the significant impact that business has had on education and educational policy. A large amount of research exists on the history of school reform and the development of educational policy, but none of the research examined...
The tendency of wood to shrink and swell with changing moisture content remains as one of the most significant challenges to using wood in its many applications. Viscoelastic Thermal Compression (VTC) has been shown to significantly increase the density, strength and stiffness of wood. However, dimensional stability is still a...
The role of unusual geologies in plant distribution and form is well-known. Serpentine (ultramafic) soils exert a particularly strong influence on plants, as evidenced by a high level of endemism and the morphological and physiological traits displayed in adaptation to the extraordinary chemistry of these substrates. Adaptation may lead to...
The objective of this dissertation is to theoretically and empirically examine the role of firm heterogeneity in terms of productivity and skill-intensity in the agglomeration process and the effect of agglomeration on regional economic development.
In the first essay, I analyze the effect of trade liberalization on agglomeration of high-...
"Watchmen: as a Work of Literature" asserts the premise that literature contains complexity and themes, as well as literary devices, and decided that is a graphic novel meets these requirements, it is also considered literature. The graphic novel Watchmen is analyzed like a literary text, and the narrative devices, literary...
