Open field burning is the lowest-cost method of harvest residue
disposal used extensively by grass seed producers in the Willamette
Valley of Oregon. The beneficial effects of open field burning include
effective disease control and increased seed yields. However, smoke
produced by open burning in the late summer pollutes valley...
Many centers of population in the Pacific Northwest are dependent
upon employment in the forest based industries. Mary of these
timber dependent communities look to the public forests for their raw
wood requirements. In some localities the installed capacity has outstripped
the local wood supply. This necessitates reaching into other...
The Problem
The general purpose of this study was to determine the
completeness and adequacy of student personnel services in
Negro colleges of the South Atlantic States. Specifically,
the problem was (1) to identify and analyze the nature of
student personnel practices in Negro colleges of the South
Atlantic States;...
Consider the bole of a tree to consist of a linear elastic material that is orthotropic with respect to the cylindrical coordinates. When the bole of a tree is subjected to resultant loads in the directions of the Cartesian base vectors, the S₁₁, S₂₂, S₃₃, and S₁₂ stresses in Cartesian...
Great Basin Canada goose (Branta canadensis moffitti) productivity and nesting habitat utilization were studied on the Columbia River within the boundaries of the Umatilla National Wildlife Refuge during the springs of 1974 and 1975.
Five islands, BL-1, BL-2, SD-1, SD-2, and Telegraph Island (TI), contained 88 percent of the nesting...
This study includes an analytical solution to the wave-current
barrier interaction problem and large scale experiments to validate the
theory.
The boundary value problem is solved mathematically by characterizing
the flow field and barrier motion separately, then coupling
the relationships with the appropriate kinematic and dynamic boundary
conditions.
The flow...
Sand dunes are used as indicators of wind
power potential and examples are presented of their application
as a prospecting technique at four study sites in
the Central Columbia River Basin. Aerial reconnaissance
is combined with interpretation of photography and topographic
maps as a basis of sand dune analysis. Sand...
