The project (partially) described in this paper was the result of an attempt by the Navy to use software complexity metrics to assess the complexity of Naval avionics software. In particular, the project consisted of computing a variety of software complexity metrics for CMS-2M and AYK-14 assembler source code and...
Equal value gray scales are frequently employed by cartographers to choose gray tone area
symbols. Several researchers have tried to quantify perceived gray tone as a function of percent area inked or
reflectance but results have varied. The influence of pattern and texture on gray tone perception is considered
a...
Past disasters such as mercury poisoning in Minimata, and new problems such as tributyltin impacts on shellfish have maintained public concern about problems caused by chronic discharges of hazardous materials into marine waters (Clark, 1986; U.S. Congress, 1987). However, hazardous chemical spills in coastal waters typically escape public attention. Unlike...
This is an Oregon Dept. of Fish and Wildlife internal discussion paper about a proposal to create a new clam bed in front of the Hatfield Marine Science Center, and to explore releasing Manila clams or native clam species seed stock in order to enhance recreational clamming in Oregon.
Production of hardwood lumber (mostly red alder) has been a small but growing part of the forest products industry in the Pacific Northwest. In laboratory tests, Rodewod® 200 EC plus borax protected alder at nearly all levels tested. Eight other chemicals provided some protection at the highest level tested. Fungal-stain...
In March, 1990, about 24 crabbers, seafood processors and seafood vendors met in Newport for a workshop and a chance to give input to ODFW. One issue addressed was setting the start date for the commercial crab season to minimize the incidence of soft crabs that are not filled out...
Slope-aspect is the compass direction of a slope at a particular location on a given
surface, and can provide a graphic tool for people who require an understanding of
the pattern of slope-aspect variation across a landscape. Slope-aspect maps can be
helpful for terrain analysis, watershed management, building site analysis,...
This is an Oregon Department of Fish and Wildlife exhibit made before the December 5, 1990 meeting of the Oregon Fish and Wildlife Commission. The exhibit contains a briefing on a citizen’s petition to prohibit commercial crabbing at the mouth of Alsea Bay. The exhibit includes the petition, a Waldport...
Environmental restrictions have induced many sawmills to seek alternatives to pentachiorophenol (penta) and similar chlorinated phenols for controlling mold and fungal stains on green lumber during storage and shipment. For that purpose, ten alternative stain preventives were evaluated against a traditional penta product (Permatox 101) on studs of Douglas-fir [Pseudotsuga...
The main purpose of this research is
1. To analyze the terrain/climate of Cape Verde, with emphasis on cloud
cover, and its effect upon satellite image acquisition.
2. To use a methodology that allows the use of AutoCAD to map these clouds effect in image acquisition to permit viewing whatever...
This is an exhibit prepared by the Oregon Department of Fish and Wildlife for the Oregon Fish and Wildlife Commission. Washington State had delayed the opening of their 1989-90 commercial crab fishery, and this delay disrupted fisheries in other states up and down the West Coast. The main focus of...
To learn whether vine stems are less structurally stable than shrub stems, I studied the architecture, anatomy, and mechanics of western poison oak (Toxicodendron diversilobum), a plant that grows as a vine when provided with external support but otherwise as a shrub. I assessed the relative structural stabilities of vines...
This investigation is focused on smallmouth bass in the Umpqua River system. This investigation contains methods of fish sampling used and, later, describes which methods were more effective for specific tasks. It includes population size, density/structure, mortality rates, and age/growth data regarding the smallmouth bass. See also: Umpqua River smallmouth...
"A study of smallmouth bass in the Umpqua River System was initiated in 1987 and continued in 1988. Results of that work were reported in a progress report. The study was continued in 1990 after a one-year lapse. This report summarizes results of the work conducted in 1990. Objectives of...
"The Service is proposing to establish the Siletz Bay National Fish and Wildlife Refuge by initially accepting a donation of 46 acres of salt marsh, acquiring up to 793 acres of land, and cooperatively managing 1,060 acres of tidelands with the State of Oregon... The primary need for the Service...
Excised stem segments of vines had higher specific hydraulic conductivies (flow rate per pressure gradient per stem transverse area) than did trees during the dry season in a deciduous forest in Jalisco, Mexico. Vine species averaged from 2.7 to 203 x 10-3 m2 MPa-1 s-1 and tree species from 0.8...

This report presents data and information developed during the 1988 crop season. Some of the work is done cooperatively with OSU staff members in several departments in the College of Agricultural Sciences. There is close cooperation with the OSU Agricultural and Home Economics Extension Service in reporting and making information...
