In 1968 the Oregon Fish Commission (now Oregon Department of Fish and Wildlife) initiated P.L. 88-309 funded studies to develop techniques to spawn and rear several species of bay clams. After our successful spawning and rearing studies, we planted the laboratory-produced juvenile clams on various tideflats of several estuaries to...
Seismic refraction, reflection and gravity data obtained
across the Peru continental margin and Nazca Plate
at 9° S. permit a detailed determination of crustal structure.
Complex structures normal to the profile require the
development of a ray trace technique to analyze first and
later arrivals for eleven overlapping refraction lines....
In this thesis we define two nxn matrices T and S to be isoconjunctive if there exists an nxn nonsingular hermitian matrix H such that T = HSH. We then proceed to establish necessary and sufficient conditions that two nxn matrices T and S be isoconjunctive in the case where...
The Oregon sockeye salmon virus (OSV) was isolated from
diseased sockeye salmon (Oncorhynchus nerka) fingerlings in 1958
by J. L. Fryer. Experimentation performed prior to the research
reported herein indicated that the OSV contained essential lipids, was
100 to 300 mμ in size, and possessed RNA (presumptively identified
by 5-bromodeoxyuridine...
Dissolved oxygen profiles made with an in situ polarographic
device reveal structure in the form of inversions and gradient
changes in the 100-600 meter depth zone off Oregon. Inversions
10-70 meters thick are traced over distances of 40 miles in some
cases and are bracketed by a distance of 8...
This study consisted of determining some of the conditions for
culture of young English sole (Parophrys vetulus Girard) in the laboratory.
Rearing of the larvae to the juvenile stage was attempted
unsuccessfully; techniques used and problems encountered during culture
are discussed. Growth of juveniles was studied at combinations of
temperatures...
The behavior of a stream upon entering a field reservoir was
studied at various stages of stratification. The principal field techniques
included fluorometric and temperature surveys. General
relationships were obtained, between dimensional and locational characteristics
of the inflow current and the thermal structure of the
impoundment. As predicted by analytical...
This thesis presents a linear programming package that uses an
algorithm and data storage method efficient enough to solve a medium
sized linear programming problem (250 variables and 100 constraints)
on a minicomputer with small core memory space (4000 bytes).
In this routine the problem is formulated by the use...
