Elodea densa Planch. was exposed to diquat (6, 7 dihydrodipyrido [1,2-a: 2', 1'-c] pyrazinediium dibromide), alone and in combination
with disodium endothall (disodium salt of 7-oxabicyclo [2.2.1]
heptane-2, 3-dicarboxyclic acid), and copper sulfate pentahydrate.
Studies were conducted in coastal lakes of Oregon infested with E.
densa. Dichlobenil (2, 6 dichlorobenzonitrile)...
The "cotton fur" (CF) condition in mink has been shown through
investigations at Oregon State University to have three basic causes,
viz.: 1) Feeding diets of fish comprising certain species of the cod
family, including: Pacific hake, Atlantic whiting and Alaskan pollock;
2) Inclusion of rancid fats in the diet;...
In introducing the method of electrical images we first consider
the elementary problem of finding the electric field of a single point
charge and an infinite conducting plane. Then a problem involving a
conducting sphere and an exterior point charge is investigated and
the results are applied in the solution...
The dramatic upsurge of contract-supported archaeological activity,
generated by legislative action, has precipitated an increase
in information about Oregon's prehistoric peoples. This information,
however, has not been presented in a format which can be easily

schools. Particularly when viewed from the historical perspective
of the times in which it was initiated, the guide group concept
offers an opportunity to examine the...
The purpose of this research was to determine if
overland flow and sediment production were different in
logged (on snow, frozen soil, and prescribed skid trails)
and nonlogged sites in a Pinus ponderosa Laws.!
Symohoricaroos albus Laws. community in the foothills of

Fifty radiator repair shops were randomly selected from nine counties that comprise the highest population density in Oregon. All 50 worksites were visited; of these 50 worksites, 22 were...
Major (Fe, Mn, Al) and minor (Cr, Mo, Pb, Zn, Cd) element
analyses of metalliferous sediments in cores from the East Pacific
Rise and Bauer Deep indicate that the Bauer Deep sediments are
similar in chemistry and origin to metalliferous sediments of the
East Pacific Rises.
Fe, Pb, and Zn...
