Twelve rock units, from upper Eocene to middle Miocene are exposed in the Nicolai Mountain-Gnat Creek area. They are, from oldest to youngest: Pittsburg Bluff Formation; Oswald West mudstone; Big Creek sandstone, upper Silver Point mudstone, and
Pipeline mudstone members of the Astoria Formation; Depoe Bay Basalt; Grande Ronde Basalt;...
In many regions of the world, a significant portion of the surface water originates in mountain headwaters where the timing and magnitude of streamflow is largely dictated by the seasonal storage of precipitation as snowpack and long-term storage as glaciers. Accumulation, persistence, and melt of snow and ice are functions...
The thermal energy storage requirements for a district heating
system utilizing geothermal energy is evaluated with respect to the
system design heating load and local climatic conditions. The
local climate pattern is represented by a series of events which
characterize the nature and sequence of the cold spells that can...
The purpose of this qualitative research study was to examine the role a rural community college plays in the development of its community, using a holistic, community-based lens that considered college and community context, interactions and results to answer the question: How does the rural community college impact the development...
The problem addressed is absence of a class of objects in a finite set of objects, which
is investigated by considering absence of a species and absence in relation to a threshold.
Regarding absence of a species, we demonstrate that the assessed probability of absence
of the class of objects...
Given the growing human security implications resulting from the high rates of change in social-ecological systems, the general question motivating this research is: how can the traditional security establishment respond to rising non-traditional threats? This question comes from the ongoing debate of whether military resources should be used in some...
Wood remains the most popular material for deck construction. For centuries, consumers have chosen wood because of its desirable qualities and aesthetics. In recent years, wood plastic composites (WPC's) have seen rising demand as alternatives to wood decks, despite a large price premium. In addition, the removal of CCA treated...

Great blue heron (Ardea herodias) eggs and prey items were collected from six colonies on the Columbia and Willamette rivers and Puget Sound during 1994-95. Contaminant concentrations, reproductive success, and biomagnification factors (BMFs) were determined and effects of residue levels were measured by H4IIE rat hepatoma and ethoxyresorufin-O-dealkylase (EROD) bioassays....
