Dicamptodon is the single, extant genus of the
ambystomatid subfamily Dicamptodontinae. Two species, D.
ensatus (Eschscholtz) and D. copei Nussbaum are recognized.
D. ensatus is found in the forested, mountain regions of
northwestern California and western Oregon, in the Willapa
Hills and Cascade Mountains of Washington, in extreme
southwestern British...
Non-point agricultural contaminants, such as nitrogen, may lower groundwater quality and thereby impose health and environmental risks. The objective of this study is to evaluate tax policies to control agricultural pollutants in a spatially heterogeneous and dynamic setting. The focus of the study is non-point source nitrate contamination of groundwater...
Most higher plants have evolved with an obligatory symbiotic relationship with my corrhizal fungi. Epigeous mycorrhiza formers have their spores dispersed by air currents, but hypogeous mycorrhizal fungi are dependent upon small mammals as primary vectors of spore dissemination. Mammalian mycophagists defecate within the coniferous forest ecosystem, spreading the viable...
The filbert is propagated by layerage and a faster method is
needed to keep pace with the rapidly expanding industry and the demand
for new cultivars. Propagation by seedage and graftage were the
two methods selected for evaluation in the research. Seed experiments
were initiated to identify optimum treatments for...
The purpose of this study was to compare the child behaviors of young children with autism spectrum disorder (ages 44-91 months) in different play settings. The hypothesis states that more positive child behaviors will be observed in the motor-based play setting compared to the free play setting. This study observed...
The Hanford Nuclear Reservation drew public ire during the 1980s and 1990s when activist groups forced the declassification of 19,000 documents and discovered proof of accidental and intentional releases of radioactive materials into the environment. These releases had been kept from the public. Although many locals had for decades wondered...
The ability to develop mobile applications for smartphones and tablets is an increasingly valuable skill in today’s labor market. This thesis details the development of the mobile application Drone Drop from beginning to finish. I first describe the background research conducted to learn about programming languages and other tools used...
Virtual environments and simulations are being used increasingly to both visualize and understand data as well as to create scenarios for training and analysis purposes. In this paper, we are interested in the use of simulation and visualization of interactive virtual agents to create realistic motions for training scenarios. We...

Desktop widget engines have emerged as an alternative for completing simple tasks without the need for a full-blown application or constant user interaction. Widgets can simply display data in a compact and visually appealing manner (such as stock tickers, weather forecasts, and news notifications), or go so far as to...
