Biological studies were conducted on a histozoic myxosporidan
Myxobolus insidiosus (Wyatt and Pratt, 1963) from the musculature of
Oncorhynchus tshawytscha (Walbaum). This organism is known to
occur in spring chinook salmon in Oregon and coho salmon O. kisutch
(Walbaum) in Washington. In addition Myxobolus kisutchi (Yasutake
and Wood, 1957) was...
The objective of our study was to investigate the effect of selenium on
selenoprotein W. Western blot analysis indicated that selenoprotein W is present in
muscle, brain, testis and spleen of rat tissues. Tissue distribution of selenoprotein W
was not altered in rats fed various selenium levels. Among muscle, brain,...
Twenty five years' worth of science indicates that the world can expect a number of climate change impacts. Increasingly, local municipalities, businesses and communities of people are becoming more concerned about what to do, yet they are looking for ways to best work together under these conditions. Communities must adapt...
Bioavailability (BA) of vitamin B6 (B-6) from foods may be
limited. The knowledge of the BA of B6 from food is important in
that this would help to understand if the B6 present in the diet of
individuals will meet the requirements for this vitamin.
The purpose of this study...
The spatial organization of farm units in Polk and Linn counties
in the mid-Willamette Valley has undergone significant change over
the past 30 years. Whereas most study areas operations in the
1930's and 1940's consisted of small family owned farms with contiguous
land bases, present mid-Willamette Valley units vary considerably...
Chloroplast DNA (cpDNA) variability and phylogeny were
studied via analysis of restriction site mutations and DNA
sequencing in a complex of three closely related species of
pines: Pinus radiata D. Don, P. attenuata Lemm., and
muricata D. Don. Genomic DNA from 384 trees representing
20 populations in the complex were...
A population of the Douglas-fir cone moth, Barbara colfaxiana
(Kft. ), was studied on the Buckhead Seed Production Area, Oakridge,
Oregon, during 1971 and 1972. A method of estimating cone and
insect populations is presented. Factors contributing to the mortality
of B. colfaxiana are discussed, with resinosis being the critical...
3D vector tomography has been explored and results have been achieved in the last few decades. Among these was a reconstruction formula for the solenoidal part of a vector field from its Doppler transform with sources on a curve. The Doppler transform of a vector field is the line integral...
