The three most expensive wildland fire suppression seasons have occurred since 2000, each exceeding $1 billion. Many problems and issues have been highlighted including the grounding of the federal air tanker fleet, training problems with private contractors, overspending, poor management strategies, negative public pefceptions, and the inability to utilize the...
Powder injection molding (PIM) is a net fabrication technique that combines the
complex shape-forming ability of plastic injection molding, the precision of die-casting,
and the material selection flexibility of powder metallurgy. For this
study, the design issues related to PIM for fabrication of thin-walled high-aspect
ratio geometries were investigated. These...
The 13 personal essays in Water over Stones: Oregon Watershed Stories explore the author's experiences in dozens of Oregon watersheds. Using the genre of the personal essay, the author, a fifth-generation Oregonian and amateur ecologist, writes about her life and family relationships in stories that are saturated with the waters...
Scientists and land managers realize that integrated weed management (IWM) strategies are needed to attain successful and lasting improvements of weed infested landscapes. At this time no broadly reliable and environmentally safe IWM strategy has been developed to control exotic annual grasses that dominate many ecosystems of the northern Great...
Induction motors are considered to be the work horse in all types of today's industries. In all mechanical applications, using an induction motor is considered to be the preferable, if not the optimum selection. Their failures, on the other hand, cause an interruption equal to their volume of dependency in...
The Seebeck coefficient is examined in the high temperature limit, using an approach based on a grand partition function containing Hubbard Hamiltonian interaction terms. Although the carriers of interest occupy localized Wannier states, this work is prefaced by the case of delocalized Bloch states, which is examined using Boltzmann transport,...
Across western Oregon, Washington, and British Columbia, forest management practices over the past century reduced the amount of late-successional forest while
simultaneously increasing the amount of young (less than 80 years old), managed
Douglas-fir (Pseudotsuga menziesii) dominated forests. Recently, concerns over loss of late-successional habitat pushed management objectives on public...
