Beginning in the late 1960s and throughout the past decade, unusual, perhaps neoplastic, large cells with rather consistent characteristics were described in mussels, clams, and oysters from several bays in the United States and the United Kingdom. The large, characteristic cells are thought by many workers to be abnormal leukocytes...
Proceedings of the 54th Annual Western Orchard Pest and Disease Management Conference, held January 16-18, 1980 at the Imperial Hotel in Portland, Oregon.
When a shade ring is used to shield a pyranometer from direct solar radiation, a correction to the
measured diffuse radiation is necessary to account for diffuse radiation intercepted by the ring. A general
analysis is developed to relate shade-ring corrections to the radiance distribution of diffuse radiation. The
corrections...

Surface erosion can be initiated by forest practices such as
timber harvest, road construction, and site preparation. A variety
of management and control measures can help reduce
this erosion. Surface erosion is generated by soil and operational
conditions that are conducive to or cause disturbance
and compaction. By using good...
Foraging honey bees (Apis mellifera L.), exposed to birdsfoot trefoil (Lotus corniculatus L.) bloom treated with microencapsulated methyl parathion, continued to display pollen and midgut microcapsule contamination up to 9 days postspray. Nearly 10% of all pollen storage cells examined in combs taken from honey bee colonies exposed to the...
The purpose of insect and disease damage surveys is to estimate losses caused by various pests, so that the land manager can prescribe appropriate management action. Systematic ground data collection systems provide to the land manager loss data that can be used for cost benefit analysis, management plans, environmental impact...
This report includes information concerning experimental use of unregistered pesticides or unregistered uses of pesticides. Experimental results should not be interpreted as recommendations for use. Use of unregistered materials or use of any registered pesticides inconsistent with its label is against both Federal Law and State Law.
This paper describes the results of a time-study conducted
near Grand Ronde, Oregon, to determine the production
rates and total harvesting costs of a cable thinning in a
young stand. The stand had a species mix of 48 percent
western hemlock (Tsuga. heterophylla- (Raf.) Sarg.), 45 percent
Douglas-fir (Pseudotsuga meuziesil...
Over the last decade a new perspective on how forest ecosystems operate has emerged. Ecosystems appear much more flexible than we once thought. Even the most persistent is still evolving in composition. Yet for all their diversity, very similar processes are seen as operating in all forests, providing a point...
This compilation of theses and dissertations (a part of the OSU Bibliographic Series) for the period 1970-1977 reflects this university's emphasis on research and graduate study. It may be viewed as an indicator of the contributions made to the state of Oregon through graduate study and research at Oregon State...
This index provides access to infonnation about women in 102 books and journals. The information contained in each entry is only as good as the original and the quality varies considerably. Much of this infonnation has not before been easily accesible in this form. My hope is that this index...
Report of the Oregon Fish and Game Commission’s transactions and operations for July 1, 1978-June 30, 1980. This report summarizes fish and game resources for the biennium, as well as research conducted and an outline of activities to educate the public on operations. It contains information on game such as...
In my application to the Marine Resource Management program I stated that it was ray intention to forge a new career by combining my training and experience as a Naval officer with an education in marine science. As my education at Oregon State progressed through the first year and I...
"Because forest managers and geneticists need basic information about natural variations in populations of red alder, we studied conelet and seed characteristics, as well as early growth, of this species along an elevational transect in the Coast Range of Oregon."--P. [1].
This report is a summary of my experience as an intern marine extension
agent with the Florida Marine Advisory Program (MAP) during the
winter of 1980. I contacted Marion Clarke, Florida MAP Coordinator,
about the possibility of "interning" with one of the marine extension
agents, so that I could develop...
During the W7711A cruise, from November 5 through November
13, 1977, a series of measurements were made on the hydrography, suspended particulate matter (spm), nutrients, first and second trophic level biomasses, primary productivity and zooplankton species for the purpose of gaining concurrent winter time information on these parameters. The cruise...
This document is a summary of the activities of the Wildlife Division for the period of July 1, 1978 to June 30, 1979. It includes numbers of hunting licenses, increased prices of furs, and both large and small game statistics including elk, bears, pheasants, and quail. The document also discusses...
Observations of wind speed and direction, air and sea temperature, and solar radiation were obtained from an array of buoys in JASIN. The observations were analyzed to show spatial and temporal variability. Spectra of wind speed and air and sea temperature were computed to illustrate the distribution of variance over...
This paper includes the proposed "Willamette River Greenway"
section of the Linn County Comprehensive Plan and "Criteria
and Standards for Greenway Development Permits," the proposed
implementing ordinance.

The angular distribution of diffuse radiation was measured from May 1976 to May 1977 with a set of
purpose-built actinometers. Radiance distributions for 98 overcast hours were fitted well by an expression
similar to the conventional function for a 'standard overcast sky' (SOC). However, values of the coefficient
b averaged...
"This report concerns one aspect of the marina permit evaluation process: water quality impacts related to marina circulation and flushing efficiency. These physical properties vary with the wind, tide range, water density and physical dimensions of a marina. Water quality is affected by the degree of flushing, and sediment redistribution...
Horizontal transects of fluorescence measurements have been used extensively to investigate phytoplankton patchiness. Variance spectra have been calculated from these data, thus quantifying spatial heterogeneity as a function of length scale. Analysis of such fieldwork and associated theoretical investigations is based on the assumption that horizontal patchiness is isotropic. Three...

We have developed a method for determining the response of a static, partially ordered ensemble of molecules to various types of electromagnetic probes. In our formalism a physical model is constructued for the orientational distribution function, which is represented as a volume integral over a set of weighting functions. Procedures...
