This circular describes research activities of the Oregon State College School of Engineering during the school years 1958-59 and 1959-60. These activities are listed according to the engineering department in which the research is carried out. In each department section are described facilities of the department, research projects, and graduate...
Field trials of weed control research on several vegetable crops are reported in this summary. Unless otherwise indicated these trials were conducted at the Vegetable Crops Research Farm at Corvallis. Soil type at this location is a silty clay loam and all plots were sprinkler irrigated as needed to provide...

This is an account of an experiment in tagging and releasing Dungeness crabs into Yaquina Bay in early 1957. Did they travel to the ocean, to another bay, or did they stay in Yaquina Bay?
For the past six years a bacterial infection has been the cause
of large losses of adult, spawning, American shad (Alosa
sapidissima) in the Coos, Millicoma and Smith Rivers of Oregon.
There was a sizable commercial fishery for shad in these rivers
and losses of fish due to this infection...
A biosystematic investigation was undertaken in 15
species and three subspecies of the genus Aster, in western
North America. Previous studies had been based entirely on
external morphological features, and it was believed that
much could be learned about the natural affinities of the
taxa by exploring their cytological and...
A taxonomic investigation was made of 24 taxa belonging
to the section Trichodium (Michx.) Trin., of
Agrostis, and the genus Podagrostis. Experimental methods
were employed, including: uniform garden culture of transplants
and plants grown from seeds collected in natural
populations; breeding studies; physiological and phenological
investigations; cytological studies; ecological
studies...
The probable pollution distribution and flushing times have been
calculated for the Columbia River Estuary, a coastal plain estuary.
The pollution distribution was determined by the fresh water fraction
and by the diffusion equation. The flushing times were calculated by
the modified tidal prism method and by the fraction of...
An investigation was made to test the method of Head on the
flow about a circular cylinder with suction. The method of Head is an
approximate method of obtaining solutions to the boundary layer equations.
The method was adapted to the digital computer to facilitate
performing the calculations, and a...
This study reports the design, construction, and evaluation of an automatic cardiac massage device and support system. The design incorporates the principle of a cardioplethysmograph operated in reverse, such that pneumatic power fed to the prosthesis will mechanically impart a massaging action to the heart. Basically, the prosthesis is a...
The problem of this thesis is to evaluate small tracts of public
domain land as to their best use in an area where the Bureau of Land
Management desires to terminate managerial responsibilities. The
area chosen is located in the Prineville District, Bureau of Land
Management and is within the...
The design of a preamplifier for use with a piezoelectric transducer is generally approached from the point of view that an extremely high input impedance is required to obtain low frequency response. However, piezoelectric transducers are essentially charge generators and this fact may be utilized in designing preamplifiers to be...
Histones are presumed to be of chromosomal origin and provide
both structural and functional elements for chromatin. In like
manner the ribosomal proteins are of ribosomal origin and have
analogous roles. Considerable controversy over their cellular roles
exists because of the inability to compare directly both groups of
proteins. In...
Four cell lines derived from embryonic tissues of four species
of salmonid fishes, and one from a hepatoma in rainbow trout have
been established in this laboratory. The species represented are
chinook, coho, and sockeye salmon; and steelhead and rainbow trout.
All of these lines have been cultivated for approximately...
