Several types of instream structures were evaluated for their
potential to provide rearing habitat and to increase reach carrying
capacity for steelhead trout (Salmo gairdneri). Evaluation was
conducted in each season over the course of 1 year.
Blast pools created in bedrock glides increased the carrying
capacity of stream reaches...
The primary purpose of this study was to examine the relationship
between managing emotions scores and the variables of education level, affiliation,
number of relationships, commitment to relationships, and parental
divorce.
The instrument used in the study was the Iowa Development
Inventory-B with questions added to measure behavior relative to...
Dissolution profiles of two commercial products (Motrine and Rufen®) were analyzed and compared at 8 pH levels, ranging from pH 2.0 to pH 8.0. It was demonstrated, as expected, that the rate and extent of ibuprofen dissolution dissolution was pH dependent. In vitro dissolution characteristics of the ibuprofen solid dispersion...
Efficiency of nitrogen fertilizer uptake by soft white winter
wheat (Triticum aestivum L.) was measured over two cropping seasons
across a range of soils and cropping histories in the Willamette
Valley. Fate and potential losses of applied nitrogen were also
assessed over a seventeen month period.
In both cropping seasons,...
During the last five years, interest in productivity-based group incentive plans for mill operations in the forest products industry has increased. In a 1983 monograph in this series titled "Company /Employee Gainsharing Programs," Michael B. McKay anticipated this trend. In that monograph, he defined "gainsharing" as a "group incentive plan."...
Hard red winter wheat has the potential to be an alternative crop
in the Pacific Northwest, however percent grain nitrogen has been
unacceptably low and grain yields have been about only 80% of soft white
winter wheat. During the late spring and the summer months there is
usually little rainfall,...
This compilation of theses and dissertations (a part of the OSU Bibliographic Series) for the period 1970-1977 reflects this university's emphasis on research and graduate study. It may be viewed as an indicator of the contributions made to the state of Oregon through graduate study and research at Oregon State...
The virulence of selected isolants of infectious hematopoietic
necrosis virus (IHNV) were differentiated and correlated with
electrophoretic mobilities of virion structural proteins by sodium
dodecylsulfate polyacrylamide gel electrophoresis. A type 1
electropherotype of IHNV was more virulent for kokanee salmon
(Oncorhynchus nerka) and a type 2 strain more virulent for...
The semi-arid regions of the Pacific Northwest are
characterized by a high degree of annual temperature and
precipitation variation. As a result of this climatic
variation, dryland nitrogen fertilizer trials on fallow-
,wheat rotations typically demonstrate a variable response.
Wheat growers in the area must not only cope with this...
