Between 43° 17' and 43° 21' north latitude along the south-central coast line of Oregon lie the collecting grounds adjacent to the Oregon Institute of Marine Biology. These 10 miles of coast line, between Coos Bay and Cape Arago, provide an assortment of intertidal environments ranging from the protected brackish...
The disposal of dead birds on the average specialized poultry farm often becomes a burdensome problem that is not satisfactorily handled. The average annual mortality of poultry in the United States is about 20 percent. On a poultry farm with 2000 laying birds, therefore, one may expect to lose about...

Experiments were conducted to determine survival, growth, and accumulation of HEOD (major component of dieldrin) in the tissues of steelhead trout (Salmo gairdneri) embryos, alevins, and fry exposed to dieldrin concentrations ranging from 0.012 to 52 ppb. The fish were held in specially designed exposure chambers provided with continuously renewed...

For twenty-two years, I observed trees and shrubs planted for windbreaks in eastern Oregon. In this paper some conclusions are drawn, although I will be the first to emphasize that the knowledge we need and do not have would fill a much more extensive report. My observations and field work...
An estuary, unlike the open ocean, is a dynamic system that is continuously undergoing changes in its physical and chemical properties. Marked fluctuations in the levels and kinds of nutrients, temperature, and salinity are normally found in estuarine environments. These changes occur principally as a result of freshwater intrusions, tidal...

Under July 1, 1972 - June 30, 1973 cost levels for the Little White Salmon and Willard National Fish Hatcheries, small budget reductions made by reducing expenditures for fish food resulted in sharp increases in average total cost per pound of salmon produced.

The following bibliography was first prepared in April 1974 for use as a working bibliography on the State/Federal Dungeness Crab Management Program. The present collection combines the articles appearing in the 1974 report with those that have appeared through June 1976.

Starting in the 1960's, the demand for recreational properties nationwide experienced a great surge. [Reilly, 1973; David, 1969; Hoover, n.d.; ASPO, 1976]
A number of studies have been done of the impact of recreational subdivisions on local taxes. [Tillson, et. al. 1972; Thompson and Myrick, 1975; LeJeune, 1972; Moss and...
During 1975 and 1976 a sedimentation study was conducted in the Bear Creek watershed, located in the southeastern corner of central Oregon's Crook County. A Rocky Mountain infiltrometer was used to simulate high intensity rainfall over 468 sedimentation plots. Rainfall and runoff were measured and a sample of the runoff...
Results of 1977 and 1978 field trials of weed control research in horticultural crops are given in this report. These studies were conducted by the research staff at Corvallis.

A general model of interactive problem solving is described. The model views interactive problem solving to be the product of cooperating subsystems. The operative subsystem selectively attends to and manipulates problem relevant information in search of a solution. The descriptive subsystem is capable of interpreting this behavior and of discussing...
A tour of a graph (digraph, or sequential machine) is a sequence of nodes from the graph such that each node appears at least once and two nodes are adjacent in the sequence only if they are adjacent in the graph. Finding the shortest tour. of a graph is known...
G. Spencer Brown's book Laws of Form has been enjoying a vogue among social and biological scientists. Proponents claim that the book introduces a new logic ideally suited to their fields of study, and that the new logic solves the problems of self-reference. These claims are false. We show that...
An operator calculus for transforming assignment statements, loops, and choice constructs into equation-of-state expressions is shown to be powerful enough to synthetically execute a given computer program and its test data. A demonstration of the program is equivalent to applying an operator formalism to the equation-of-state in order to reduce...
Microprogramming has evolved since its introduction in 1951 by Maurice Wilkes. The most significant change that has taken place is the recent growth of interest in user microprogramming. However, user microprogramming is a difficult task because of various complex and intricate features of the host processors. A microprogrammer must be...
Context-free grammars with graph control provide a general framework for the various types of context-free grammars with regulated rewriting. The vertices or edges of the directed graph are labeled with the productions of the grammar. The only strings in the language generated by the grammar are those whose derivations correspond...

Recently several simply computed graph theoretic measures of computer program complexity, testing and unstructuredness have been proposed. Most of them are based on a static analysis of the program graph. One of the best known and most widely accepted is the cyclomatic number. Another is the number of knots, or...
A graph fold is the special case of a graph homomorphism where the two identified vertices are both adjacent to a common vertex. Like homomorphisms, folds are related to the chromatic number and we obtain an Interpolation Theorem for folds. If X(G) = n, then G is absolutely n-chromatic if...
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...
This monograph presents a proof grammar for a formal language containing property symbols of every finite type. The proof grammar is thus applicable to any finite level higher-order logic.
The unique features of this system are: first, its mode of presentation as a recursive discourse grammar rigorously constructed from the...
