Oregon's critical ground water area program was designed to protect
the integrity of ground water supplies under conditions of sustainable
yield. In areas where the demand for water exceeds the rate of natural
recharge, wells experience declining water levels. If allowed to
continue, this could eventually lead to severe social...
Context: Static stretching is commonly used during the treatment and rehabilitation of orthopedic injuries to increase joint range of motion (ROM) and muscle flexibility. Understanding the physiological adaptations that occur in the neuromuscular system as a result of long-term stretching may provide insight into the mechanisms responsible for changes in...
Escape from parasites in their native range is one of many mechanisms that can contribute to the success of an invasive
species. Gnathiid isopods are blood-feeding ectoparasites that infest a wide range of fish hosts, mostly in coral reef habitats.
They are ecologically similar to terrestrial ticks, with the ability...
The thermal conductivity, measured by the 3ω method, of amorphous films of Al₂P₁.₂O₆ (AlPO) deposited on Si substrates by an all-aqueous spin-coating technique is 0.93(3) Wm⁻¹K⁻¹. The thermal conductivity of a degenerately doped n-Si substrate is 85(5) Wm⁻¹K⁻¹ and of a more lightly doped p-Si substrate is 139(7) Wm⁻¹K⁻¹. The...
Cerium oxide nanoparticles were continuously
precipitated from a solution of cerium(III) nitrate and ammonium
hydroxide using a static microchannel T-mixer. Tmixer
synthesis results were compared with synthesis results
from batch precipitation. Findings show that the method of
mixing is important in the ceria precipitation process. Uniform
porous film structures and...
The 2003 Oregon Legislature directed the Oregon Department of Forestry (ODF) to convene a citizen work group to review and evaluate the ODF Salmon Anchor Habitat Strategy for state forests in northwest Oregon. In November, 2003 ODF contracted with the Institute for Natural Resources (INR) to support the SAH Work...
Our project goal is to protect and restore rare Willamette Valley upland prairie habitat at Butterfly Meadows (Benton County) from invasion by the noxious weed Brachypodium sylvaticum (false brome). Native prairies, which once dominated the landscape of the Willamette Valley, are considered among the rarest of Oregon’s ecosystems and are...
Ballast water discharges are a major source of species introductions into marine and estuarine ecosystems. To mitigate the introduction of new invaders into these ecosystems, many agencies are proposing standards that establish upper concentration limits for organisms in ballast discharge. Ideally, ballast discharge standards will be biologically defensible and adequately...
Opinions about public lands and the actions of private non-industrial forest owners in the
western United States play important roles in forested landscape management as both public
and private forests face increasing risks from large wildfires, pests and disease. This
work presents the responses from two surveys, a random-sample telephone...
