The end of the Cold War brought about changes within international political relations that resulted in expanded interest in global civil society. Such developments, like globalization and democratization, have encouraged the growth of social and political organizations. Political scientists have found that these inter-governmental and non-governmental organizations have a significant...
Biological invasions and climate change represent two preeminent threats to ecological communities and biodiversity, altering the distribution and abundance of species, disrupting existing species interactions and forming unprecedented ones, and creating novel ecological communities. Many of the most successful invasive species are also ecosystem engineers, species that physically modify the...
Novel fluidic devices that utilize an array of microchannels to achieve their designed purpose are discussed. Examples of devices include: fuel reforming using Microreactors, chip cooling using microchannel heat sinks, and microchannel devices used for biological applications. The devices that have directly contributed to this research include: a microchannel water...
Average characteristics of subsidence inversions associated with
the Pacific High have only been documented for areas along the U.S.
West Coast and over the tropical eastern North Pacific Ocean. This
study, which is based on 3414 upper-air soundings for June through
September of 1964 and 1965, shows the average summer...
The Risø data were analyzed for variations in the surface roughness
lengths. The method of analysis was tested on the Wangara data
and proved satisfactory at this homogeneous site.
Annual mean surface roughness lengths were determined for
three wind speed categories and three stability categories. The decrease
in surface roughness...
The thesis examines the applicability of a two-dimensional flow acceleration model to describe a terrain-induced flow perturbation as measured at Yaquina Head on the central Oregon coast. The geometry of Yaquina Head together with the upstream wind values were used in estimating hilltop winds. These estimates compare well with the...
