Field and greenhouse experiments were conducted to determine the suitability of using incinerated sewage sludge ash as a soil amendment for sweet corn production on Willamette silt loam. In 1977, field plots were treated with 0, 11, 22, and 43 mt/ha of ash containing lime, in factorial combination with a...
This study was undertaken to compile a comprehensive
review of the literature and to gain a better understanding
of the host-parasite relationship in corynebacterial kidney
disease of salmonid fishes. An indirect fluorescent antibody
technique was developed which allowed differentiation
of intra- and extracellular bacteria. This technique was
used in combination...
This thesis develops a model for locating field offices for the
Motor Vehicles Division of Oregon. The locations are determined by
minimizing the total cost to the Public. This is reasonable because
the Public finances the operation and the opening of the offices
through tax dollars, and it bears the...

These proceedings arc based upon a Conference conducted at Oregon State University on May 13 and 14, I 970.
The conference was sponsored jointly by the Schools of Forestry and Business and Technology. Co-chairmen of the Conference were Professor Ray A. Yoder of the School of Forestry and Professor Lester...
The Federal Water Pollution Control Act Amendments of 1972
prohibits the discharge of seafood processing solid wastes into
navigable waters after July 1, 1977. Oregon shrimp and crab processors
must use other methods of disposal for the 15 to 30 million
pounds of solid waste generated annually. The application of...
Proceedings of the 53rd Annual Western Orchard Pest and Disease Management Conference, held January 10-12, 1979 at the Imperial Hotel in Portland, Oregon.
The effects of improved oral hygiene on the nutrition of 23
elderly institutionalized men and women were investigated. An experimental
group of 12 received professional oral hygiene treatments
three times weekly for a period of five weeks, while a control group
of 11 received only placebo work. Changes in taste...

Hydrodynamic forces on a cylinder oscillating horizontally
underwater with its axis perpendicular to the motion
were measured at the Oregon State University Wave Research
Facility. The cylinder had an outer diameter of 12 inches
and a length of 12 feet. For the data presented herein, the
maximum displacement of the...

Extensive new trackline coverage of the Chile Trench between 23°S and 34°S, including more than 60 bathymetric and seismic reflection profiles across the trench axis, allows a much more detailed study of the tectonics and sedimentation of this feature than previously possible. Sediment distribution along the axis shows a remarkable...
Random waves are often expressed as a mathematical superposition
of an infinite number of sinusoidal components. The mean square spectral
density of the water surface elevation is often called the wave spectrum.
The zero upcrossing wave heights usually have a Rayleigh probability
distribution. However, the design wave concept is still...
In the mild climate of the Pacific Northwest, the harvesting of
deciduous shade trees in wholesale nurseries is prolonged from
October to January because of autumn growth and prolonged leaf
retention. Economically, it is advantageous to defoliate nursery trees
at the earliest possible date. Premature defoliation, however, can
cause die...
The application of lime to an acid Nekia soil significantly
increased the yield of winter wheat and alfalfa in a field experiment.
Crop yields maximized when the lime was partially mixed into the surface
four inches of the soil. Thorough mixing of the lime into the
surface six inches of...
Metropolitan solid wastes and sewage sludges present a serious
disposal problem for many communities. To assess the feasibility of
disposal or utilization of these waste products on soils, a study was
initiated to evaluate plant growth and soil elemental interactions on a
loamy fine sand treated with metropolitan waste. Shredded...
Social competence has emerged in research on social development
as a construct unifying behavioral and motivational dimensions of social
development in the preschool child. It draws from theories of social
learning, cognitive development, and competence motivation. The
theoretical relevance and empirical utility of the construct indicate
the need for further...
The results of three hydraulic model tests to evaluate the stability
of a placed stone breakwater are presented and discussed. The prototype
breakwater was designed to protect offshore power and port facilities in
60 feet of water and was tested at scale ratios of 1:10, 1:20, and 1:100.
The armor...

The purpose of this investigation was to develop a
valid and reliable instrument to assess Oregon high school
students' nutrition information.
The following steps were taken in order to achieve this
purpose.
First, a review of the literature pertaining to high
school nutrition curriculum was conducted.
Second, numerous published tests...
The central purpose of this study was to determine various
views of the professional competencies required by community
college student financial aid administrators. Respondents in the
study included a student financial aid recipient, a student financial
aid administrator and a president from forty-five selected community
colleges. The major tasks were:...
This report describes the hydrodynamic testing and
evaluation of a one-tenth scale model of the FMC Wave
Attenuation Device. The purpose of the test was to quantify
the wave attenuation characteristics and structural loading
induced by a test program of monochromatic incident waves
on the submerged structure. The device was...
Problems associated with quantification of deep water wave kinematics
and dynamics are examined. Summaries of Stokes' theory and Dean's
stream function theory are reported. A computer algorithm is developed
to solve the hydrodynamic characteristics for Stokes' fifth and third
order and linear theories. Tests are initiated to verify the results...
A new technique for determining the amount of opal in deep-sea
sediments of any age is described. Using a normative calculation, a
portion of the analytical silica concentration of sediments is subtracted
as non-biogenic in proportion to the concentration of aluminum in the
sample. The ratio of SiO₂:Al₂O₃ used to...
Pastures consisting of mixtures of subclover (Trifolium
subterraneum) and grasses have responded to sulfur fertilization
on many sites in Douglas County, Oregon. The objectives of this
study were to examine specific changes in forage quality which occur
as sulfur is applied in excess of the amount required for maximum
yield...

Oregon Biography Index is intended to serve primarily as a starting point in locating biographies of Oregonians. We have indexed 47 historical volumes which are either entirely devoted to biographies or have large self-contained biographical sections. The profiles in the books vary widely in accuracy and detail. Birth dates of...

This study was initiated to determine the tolerance to copper
of Aspergillus niger, Stemphylium sarcinaeforme, Monilinia
fructicola and Fusarium oxysporum f. sp. lycopersici. Included
