This document provides the latest science and best biological judgment to assist in making management decisions. Fortunately, recent emphasis on sage-grouse conservation has resulted in a substantial number of publications dealing with a variety of aspects of sage-grouse ecology and management, summarized in the 2010 listing petition (75 FR 13910),...

PURPOSE: We analyze a recently proposed polyenergetic version of the simultaneous algebraic reconstruction technique (SART). This algorithm, denoted pSART, replaces the monoenergetic forward projection operation used by SART with a post-log, polyenergetic forward projection, while leaving the rest of the algorithm unchanged. While the proposed algorithm provides good results empirically,...

Many forest products companies in the southeastern United States store large volumes of round-wood under wet storage. Log quality depends on maintaining a high and constant wood moisture content; however, limited knowledge exists regarding moisture variation within individual logs, and within wet decks as a whole, making it impossible to...
This publication describes results of field research on the performance of hard red winter wheat cultivars in a late-planted no-till fallow system in the low-precipitation zone of Oregon and Washington.
This case study investigates how scientists who write technical marketing copy experience and resolve the tension that results from the conflicting demands of their local (company) and global (research science) discourse communities. Twelve scientists, who are currently technical marketing writers at a small biotechnology company, were interviewed by e-mail over...

The purpose of this thesis is to aid in qualitative improvements to technical support documents on the Internet. By using a generic criticism this analysis will make substantive suggestions towards the improvement of this type of document by engaging the rhetoric employed by their authors. It will discuss the history...
We present a methodology for creating a simulated foam microstructure for use in forward simulations of wave equations to quantitatively analyze the expected scattering phenomenon primarily responsible for the attenuation of interrogating signals in Sprayed-On Foam Insulation (SOFI). Our approach builds off of the popular use of Voronoi Tessalations for...
The purpose of the study was to identify a list of skills, knowledges and related factors that are common to fourteen occupational cluster areas representative of the work community of Oregon. PROCEDURES A list of skills, knowledges and related factors needed for successful employment was derived from existing task analyses...
The 1966 report was concerned with catch/effort data, reports on the statuses of major fisheries, reviews of data procedures, current research and joint projects, and dispersions of tagged fish. Other matters touched on include the developing hake fishery and increased international fishing off the Washington and Oregon coasts.
The 1967 report includes catch/effort data, a review of major fisheries, and data on dispersion of tagged fish. The Technical Sub-Committee made an important recommendation to rescind the winter closure of the petrale sole fishery. The Sub-Committee voiced concern about the growing presence of Soviet and Japanese fishing vessels off...
In 1959, when the International Trawl Fishery Committee was created, its membership was made up of personnel representing fish and wildlife agencies from Oregon, Washington, California, and the Canadian government. At its first meeting in November, 1959, the Commission created the Technical Sub-Committee. The Sub-Committee was instructed to review the...
The 1970 report considers catch/effort, statuses of major fisheries, and cumulative fish tagging data. Other topics included a groundfish bibliography, international fishery problems, and the sablefish fishery. The report includes a synopsis of otter trawl regulations and their rationale as of July 1, 1970.
The 1963 report includes status reports on important bottomfish fisheries, a review of catch/effort assessment techniques, a catalog of market sampling techniques, a summary of otter trawl regulations, and preliminary results of fish-tagging experiments.
The 1971 report includes catch/effort data and reviews of the major groundfish fisheries. The report also includes historic trawl fishery data of all agencies and their current market sampling techniques.
Standard accounts of women's relationship with technology stress women's need to overcome anxiety to achieve competence with computers. Recent studies provide evidence that this woman-anxiety-technology connection is an oversimplification of the relationship between women and computers. New literature also suggests that making computers more appealing will help girls overcome computational...
During an oceanographic cruise of the "E. W. Scripps" in May, 1939, off the coast of Oregon, four small, post-larval specimens of Anoplopoma fimitrita were taken at the surface of the sea with a dip net at two of the hydrographic stations off Cascade Head, Oregon.
Fire and other catastrophic disturbance events in the Douglas-fir forests of the Oregon Coast Range have been significant in determining the distribution of stand age classes and, hence, habitat. Except for the past half century, knowledge of fire in the region has largely been local and anecdotal. The Douglas-fir forests...
Extracting benthic oxygen fluxes from eddy covariance time series measured in the presence of surface gravity waves requires careful consideration of the temporal alignment of the vertical velocity and the oxygen concentration. Using a model based on linear wave theory and measured eddy covariance data, we show that a substantial...
"An important limitation In the study of tree roots has traditionally been the time necessary to excavate roots without injuring their fine structure. Thus, many root studies have been based on small samples and consequently contain large errors of estimation. This Note describes how large numbers of root systems from...
One-year-old container-grown Douglas-fir [Pseudotsuga menziesii (Mirb.) Franco] seedlings were outplanted on north, east, south, and west aspects on steep, skeletal Xerochrepts in southwest Oregon. After 2 years, survival rates were highest on north and south aspects, but biomass production (dry weight) was greatest on the west aspect. Shadecards, used to...

Local stability seems to imply global stability for population models. To investigate this claim, we formally define a population model. This definition seems to include the one-dimensional discrete models now in use. We derive a necessary and sufficient condition for the global stability of our defined class of models. We...
Production rates, skidding costs, and soil disturbance were compared for two partial-cut units-one with preplanned skid trails and winching and one conventional unit-harvested with a Caterpillar D-7F. For the unit with preplanned skid trails and winching, production was 11 percent less, and skidding cost per unit volume was 29 percent...

Two-year-old Douglas-fir bareroot seedlings were hoe- and auger-planted on droughty south and southwest aspects in southwest Oregon. After 2 years, no differences in height, diameter, or seedling biomass could be detected. Auger-planted seedlings survived significantly better on the southwest aspect.
Industrial training in the Fashion Apparel Industry is confronted with difficult objectives. In this industry, continual style and fabric change challenge the effectiveness of conventional industrial training techniques and concepts. To meet this challenge, the "Self-Help" training concept was developed. "Self-Help" centers around the philosophy of training sewing machine operators...
"Control of competing vegetation during establishment is one of the key links in the chain of events leading to a new plantation and, ultimately, a productive forest resource. Experience has repeatedly shown that, without adequate site preparation, reforestation efforts almost inevitably will fail. Vegetation control during the establishment period by...
