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...
We consider issues of equality and efficiency in two different school funding systems - a state-level system in Michigan and a foundation system in Ohio. Unlike Ohio, the Michigan system restricts districts from generating property or income tax revenue to fund operating expenditures. In both states, districts fund capital expenditures...
Objectives:
To evaluate the impact of the ring nematode, Mesocriconema xenoplax on the physiology and productivity of phylloxera-resistant grape rootstocks as a basis for recommending rootstocks in the Pacific Northwest. Specific objectives for 2006:
Spring: Inoculate soil with AMF and M. xenoplax. Plant vines.
Growing season: Monitor plant growth, gas...
Microclimate variables such as air temperature and relative humidity influence habitat conditions and ecological processes
in riparian forests. The increased relative humidity levels within riparian areas are essential for many plant and wildlife
species. Information about relative humidity patterns within riparian areas and adjacent uplands are necessary for the
prescription...
The transition between freshwater and marine environments is associated with high mortality for juvenile anadromous salmonids, yet little is known about this critical period in many large rivers. To address this deficiency, we investigated the estuarine ecology of juvenile salmonids and their associated fish assemblage in open-water habitats of the...
Gas hydrates, pervasive in continental margin sediments, are expected to release methane in
response to ocean warming, but the geographic range of dissociation and subsequent flux of methane to
the ocean are not well constrained. Sediment column thermal models based on observed water column
warming trends offshore Washington (USA) show...

A regional urban forestry initiative, the Portland-Vancouver Metropolitan Regional Urban Forestry Strategy, was recently created in the Portland, Oregon and Vancouver, Washington region of the United States. To inform the development of this initiative, a needs assessment survey was sent to community officials and program managers in the 30 cities...

Large river plumes modify coastal environments and can impact production across multiple trophic levels. From 1999 to 2009, the
assemblages of forage fish, predator fish, and other pelagic nekton were monitored in coastal waters associated with the Columbia
River plume. Surveys were conducted at night to target vertically migrating species,...
