A growth model is developed for coho salmon which accounts for
temperatures and feeding rates typically encountered in fish hatchery
operation. Feeding rates utilized by the model ranged from
maintenance to maximum utilizable rations. The model is derived from
an empirical equation for maximum growth rate, and a theoretical
equation...

Thirty-four current worksite health promotion programs were
studied in order to obtain comprehensive information about various components
involved in the planning, implementation, and evaluation of existing
programs, and to acquire the necessary data to develop a theory and corresponding
hypotheses pertaining to successful worksite health promotion
programs. The case study...
The aim of this study was to determine whether
counselors in training chose various specialties due to
their level of self-concept, counseling style, and
gender. It was hypothesized that there would be a
significant difference in self-concepts, counseling
styles, and gender between individuals who chose family
counseling and those who...
Concerns regarding the most effective means of evaluating
segregating generations of spring barley prompted this investigation. Three methods of selection were considered: bulk, pedigree, and single seed descent. F₆ lines derived by each method
were grown in a replicated yield trial. The effectiveness of each
method was measured in terms...
Surface and subsurface hydrological parameters affecting overland flow from cultivated land were studied in three small sub-watersheds located in the western foothills of the Willamette Valley. The sub-watersheds, which ranged in size from 0.46 to 6.0-ha, were fall-planted to grass or small grain. The parameters studied were infiltration, rainfall, runoff...

Mysids were sampled seasonally from the intertidal
zone of the beach to a depth of 61 m offshore along the
mid-Oregon coast. The seven mysid species collected
occurred in characteristic bathymetric zones, with members
of different genera occupying overlapping zones
while members of the same genus occupied largely different
zones....
Twelve Sri Lankan Alfisols were characterized for P. Soils
were incubated for three weeks with sufficient P applied
(P2) to elevate soil solution P to 0.2 ug P/g solution as
determined by sorption curves, with 75 percent of P2 (P1),
and without P (P0). For PO treatments, (a) organic P,...
