In this paper a signal-processed antenna and receiver system is
proposed and analyzed. In addition, a simulation of the balanced-mixer portion of the processing system is made on a hybrid computer
to find the bandwidth limitations for the total system. The system
utilizes both the amplitude and phase information of...
Systems Tableau is suggested as a convenient tool for the
integration of the three phases of systems theory: the synthesis of
a model from the analysis of a system; the evaluation of the model;
and the decision-making process for the design and control of the
resulting system.
From a basic...
Methods examined for the preparation of cells from tissues of salmonid fishes for primary cultivation were the fragment (explant) and enzyme dispersion techniques. Both methods were employed for the cultivation of a variety of tissues from Pacific salmon, Oncorhynchus spp., and the steelhead trout, Salmo gairdneri gairdneri. A technique was...

Data from 592 litters of pigs farrowed and raised at the
Oregon Agricultural Experiment Station at Corvallis from the spring
of 1961 through the spring of 1968 were analyzed for effects of year
and season of birth, breed, sex, inbreeding and age of dam on
measures of fecundity, growth rate...

In this thesis a method is presented for maintaining the left
ventricular wall stress of the human heart at a constant level during
the systole (active portion of the heart's cycle). This constant stress
level makes it possible to take isotonic measurements on the heart
muscles.
The left ventricle of...
It is not desirable to open crabbing seasons when a significant percentage of crabs still have soft shells following molting. Unfortunately, crabs do not molt on a fixed timetable. The problem of when to start the crabbing season is one that Oregon fishery managers have wrestled with for decades. This...
"Objectives of Oregon's Oyster Mortality Study from July 1, 1967-March 31, 1968, were: (1) to monitor oyster mortalities to detect a possible increase in mortality rate, (2) to collect hydrographic data for comparison with data from areas where high oyster mortalities occur, and (3) to furnish oysters from a relatively...
A tidal and sea level survey was begun in Yaquina Bay, Oregon,
on 8 May, 1964. A continuous recording tide gage was installed at
the pier of the Oregon State University Marine Science Center.
An harmonic analysis of the observed data was made, and the
major tidal constants were compared...
