This paper describes the results of a time-study conducted
near Grand Ronde, Oregon, to determine the production
rates and total harvesting costs of a cable thinning in a
young stand. The stand had a species mix of 48 percent
western hemlock (Tsuga. heterophylla- (Raf.) Sarg.), 45 percent
Douglas-fir (Pseudotsuga meuziesil...
In my application to the Marine Resource Management program I stated that it was ray intention to forge a new career by combining my training and experience as a Naval officer with an education in marine science. As my education at Oregon State progressed through the first year and I...
This report is a summary of my experience as an intern marine extension
agent with the Florida Marine Advisory Program (MAP) during the
winter of 1980. I contacted Marion Clarke, Florida MAP Coordinator,
about the possibility of "interning" with one of the marine extension
agents, so that I could develop...
This paper includes the proposed "Willamette River Greenway"
section of the Linn County Comprehensive Plan and "Criteria
and Standards for Greenway Development Permits," the proposed
implementing ordinance.
The interference of sulfide with the colorimetric determination of
nitrite, by the method of Bendschneider and Robinson (1952), can be
eliminated by passing the samples through a cationic exchange resin,
Dowex 50W-X8, in the zinc form. This resin retains sulfide without
affecting nitrite and the technique can be applied to...
Most measures of program complexity gauge either textual or
control flow attributes of a program. A recent addition to the field
of complexity measures, the knot metric, is a function of both these
attributes. A knot measurement reflects the degree of control-flow
tangle in a program's listing. This thesis discusses...
Industrial expansion in a small city can have
a wide range of effects upon the immediate community and
surrounding labor force area. One example of this is the
impact that Tektronix, a worldwide electronics firm, could
have on the City of Lebanon, Oregon, where a plant, initially
employing about 500...
Concern regarding the lack of genetic variability and the apparent yield plateau reached in wheat breeding have prompted this investigation. The systematic crossing of spring and winter wheat types which have evolved to form somewhat different gene pools, may provide a source of additional usable genetic variability for future yield...
Oregon English sole catch data from 0 to 80 fathoms between Coos
Bay and Cape Lookout were examined for the years 1973, 1975, and 1976.
English sole is a major target species of this inshore trawl fishery.
Comparison of depths of maximal values of catch per unit effort, effort,
and...
This study was designed to investigate the rate of pH decline, changes in protein solubility and in the water-holding capacity (WHC) of beef muscles subjected to pre-rigor electrical stimulation. Samples for the experiment were obtained from animals slaughtered at the Meat Science Laboratory, Oregon State University. Nine good quality steers...
Purebred Yorkshire gilts from a confinement managed herd were reared to test weights away from the sow and boar herd. Thirty-eight gilts weighing between 73 and 80 kilograms constituted group A gilts; 38 gilts weighing between 91 and 100 kilograms constituted group B gilts; and 47 gilts weighing 114 kilograms...
Results of a study of spatial and temporal utilization of a tidal river estuary by hatchery and wild juvenile salmonids
(Oncorhynchus spp. and Salmo spp,), of overlap in food habits of hatchery and wild juvenile salmonids, and of size and relative
abundance of associated fish species are reported in this...
This study was undertaken in a Red Delicious apple orchard in
Oregon's Hood River Valley to determine if low leaf P concentrations
were contributing to such observed, orchard disorders as poor shoot
growth, shoot dieback and. small fruit size at harvest.
Subsurface applications of lime and superphosphate had no
effect...
A rapid virus detection method was developed for Infectious Hemotopoietic Necrosis Virus (IHNV). The virus detection method could be applied to Infectious Pancreatic Necrosis Virus (IPNV) under certain conditions. It was possible to detect IHNV to a lower limit of 1.7 X 10⁴ Tissue Culture Infectious Dose for 50% (TCID₅₀)...
