Three research questions are addressed in this study: (1) To what degree do residents
support/oppose various aspects of water resources protection? (2) What factors explain
residents' attitudes? and, (3) How do attitudes vary between participants and nonparticipants
of place-based groups (watershed councils and neighborhood
associations)? The population of interest is...
Winter wheat is commonly grown in dryland cropping systems in the Pacific Northwest region of semi-arid eastern Oregon. For agronomic, economic, and environmental reasons, it is important to understand the long-term sustainability of such dryland systems. The objective of this study was to evaluate the long-term effects of tillage, nitrogen...
The development of whey beverages including whey wine has been
an area of whey utilization research. One study to produce a commercially
salable wine from sweet whey, particularly cheddar whey, was
undertaken. It included developing a process to clarify the naturally
cloudy wine, monitoring the physical and chemical changes which...
The effects of L-ascorbic acid, thiamine HC1, or L-cysteine on
acetaldehyde blood levels and disposition were investigated in acetaldehyde-
treated rats. Rats were treated with ascorbic acid (2
mmoles/kg), thiamine (0.24 mmole/kg), or cysteine (2 mmoles/kg) one
hour before the administration of acetaldehyde (6 mmoles/kg). The
results show that each...
Public Law 94-142, passed in 1975, mandated that all children receive a free and
appropriate education regardless of the extent of their handicapping condition. Handicapped
students were to be educated in the "least restrictive environment" possible. Placing handicapped
students in regular classrooms has been termed "mainstreaming." Mainstreaming has produced
concerns...
Ninety-six hour acute toxicity bioassays were employed to
determine the tolerance of juvenile coho salmon to chlorinated
stabilized kraft mill effluent (SKME). In addition the effect of
chlorinated SKME on the growth of juvenile coho salmon in six and
ten day experiments was studied.
Results of the acute toxicity tests...
In many areas of the Western U.S., diffuse knapweed (Centaurea diffusa Lam.)
has invaded into plant communities dominated by bluebunch wheatgrass
(Pseudomegnaria spicata [Pursh] A. Love). The objectives of this study were to compare
growth response of both species when grown under altered moisture and temperature
regimes while in the...
Carter Lake, a freshwater, coastal dune-margin lake,
was sampled at the beginning and end of the summer of 1986
to determine the sediment characteristics and benthic
macroinvertebrate abundance, biomass, variety, and
diversity. The distributions of major benthic habitats were
estimated by snorkeling in June and July, 1986. Water
temperature and...
