This report is concerned with the analysis of the effect of
finite wordlength, channel capacity and source rate in digital feedback
control of linear systems. The cases considered are (1) finite
wordlength A/D conversion, no feedback delay, ideal ROM (read
only memory) controller; (2) finite A/D wordlength (source rate),
state...
This is the first report on the susceptibility of salmonid fish to infection with the glochidia of the freshwater mussel Margaritifera. margaritifera using known numbers of parasites under controlled conditions. The relative susceptibility of six species of salmonid fish, 2O to 80 mm in total length, to glochidiosis was determined...
Glochidial development in freshwater mussels (Mararitifera margaritifera) located in the Siletz River, Oregon, was completed in 13 days at an average water temperature of 12.8 C. Glochidia were released by these mussels for 33 days, May 13 to June 15, 1971. The comparative susceptibility of four species of salmonid
fishes,...
Bathymetry data (measurements of the elevations of submerged surfaces like the seafloor and lake beds) are an important factor in many scientific, economic, and engineering disciplines. Bathymetric surveys are widely used for benthic habitat mapping, flood inundation modeling, marine resource delineation, and nautical charting. While this ubiquity makes the generation...
In this watershed assessment, the authors of the report summarized current conditions and data gaps within the Necanicum River watershed to help to identify how current and past resource management is impacting aquatic resources.
A group of trout that reside in streams of the desiccating lake
basins of southeastern Oregon differ markedly from other known
Salmo. Known commonly as the red-band trout, this fish was subjected
to chromosome analysis for comparison with other species of
western North American Salmo. The karyotype of the red-banded...
The Purpose of the Study
The central purpose of this study was to determine if certain
personality characteristics differ between community college persisters
and those who drop out of school. The following 12 a priori
hypotheses involving six Adjective Check List personality scales were
tested:
1. Male persisters would have...
