The demand for improved controllers creates the need for synthesis techniques which emphasize optimality. Optimality automatically infers stability. This thesis presents one such technique which is not limited to linear systems. The theory of dynamic programming is applied to the synthesis of optimal controllers with emphasis on missile flight control...

Field trials of weed control research on several vegetable crops are reported in this summary. Unless otherwise indicated these trials were conducted at the Vegetable Crops Research Farm at Corvallis. Soil type at this location is a silty clay loam and all plots were sprinkler irrigated as needed to provide...
In early May of 1969 a corn screening trial was established on the East Farm Experiment Station near Corvallis. The purpose of the trial was to determine the effectiveness and safety of a series of experimental herbicides.
The following summaries of results from experimental work with herbicides in horticultural crops cover work completed in 1967. Crops included are bush snap beans, red beets, direct seeded broccoli, cucumber, summer squash, strawberries and nursery rhododendrons. In general, weather conditions were warmer and drier than usual during the 1967 growing...
In herbicide plots on tree fruits in the Willamette Valley and at Hood River there has been a consistent correlation between weed control effectiveness and tree growth in young orchards. This appears to be particularly true of weed control during the spring and summer obtained from spring applications as compared...
Much of the research effort with Dacthal in 1961 was based on obtaining samples for residue analysis. Crops in these tests included broccoli, cabbage, cauliflower, onions and soybeans. Observations were made on crop response and weed control.
Several herbicides were evaluated for selective weed control in sweet corn in 1961. Various methods of application were compared and a comparison of planting depths was made to determine possible interactive effects with Eptam applications
A planting of three varieties of strawberries was made in the spring of 1959 with herbicide treatments designed to provide weed control through the normal life of the planting.
The crab fishery and its regulations have been discussed in many reports and several meetings. This report summarizes the areas of regulation which pose persistent problems for the Fish Commission, presents the stand of the staff, proposes action if necessary, and provides our best guess as to opposition which can...
The main problems for consideration are as follows: 1) Determine if there is biological justification for having a single coastwide season or have seasons which differ by geographical area; 2) Establish season opening(s) that on the average will occur as soon as 10 per cent or less of the crabs...
Persons concerned with the harvest and conservation of the crab resource of the Pacific Coast feel there is need for altering existing commercial fishing regulations. The following background on the matter is provided.
During the past 10 years the embryos and larvae of oysters and some species of clams have been employed to quickly assess the biological effects of various substances in marine water samples. The best materials have included some insecticides, herbicides, antibiotics, detergents, a variety of other compounds, and a few...
This report summarizes the results of crab studies undertaken during the fall of 1957 and 1958 in the Columbia River estuary. The purpose of this project was to determine the shell condition of the crabs available in this area during the period when crab fishing is prohibited in the ocean,...
Artificial radionuclides, induced in water used as a coolant in the Hanford reactors, are discharged into the Pacific Ocean by the Columbia River. Gamma-ray spectrometric measurements show that levels of 65Zn decrease in both sediments and benthic animals with distance from the mouth of the river and with depth of...

After providing a summary of the first fifteen years of the commission, this report covers the actions and regulations of the PMFC in 1962. It also contains data for research on the effects of tagging on mortality on Chinook salmon, and details the status of various ocean sport fisheries.
This issue of the PMFC bulletin focuses primarily on the English sole, including results of tagging off of various coasts and studies of various populations of English sole. It also gives a review of sablefish tagging in California and details the Oregon trawl fishery for mink food up to 1965.
This issue of the bulletin covers salmon landings, spawning of dover sole, movements of petrale sole, the pink shrimp fishery, and availability of small salmon off the Columbia River.
This issue of the Pacific Marine Fisheries Commission bulletin contains a study of annual and seasonal bathymetric catch patterns for commercially important ground fishes of the Pacific Northwest coast.
This report presents information concerning the water and related land resources of the Middle Willamette River Basin and is the result of a cooperative study by the U. S. Department of Agriculture and the State Water Resources Board of Oregon.

The Chelan Valley is one of several valleys located on the eastern slope of the Cascade Mountains contributing to the leadership of Washington in apple production. Since the nature of the activity in the Chelan Valley is typical of all these producing areas,it was selected as a case study of...
Knowledge of the pelagic organisms in vast areas of the open ocean is very limited. This is particularly true of the small nekton or swimming forms such as fishes, squid, prawns and euphausiids, which are important as intermediate animals in the food chain and are preyed upon by species such...
Compiled under the criteria: (1) statement of sources and faithfulness to them, (2) a true reflection of Indian cosmology, and (3) a written style that retains the spirit and poetry of the Indian's native manner of telling.

Drainage may be defined as the science or directing the removal of excess surface and ground water in such a manner as to safeguard the best interests of all concerned. Its ultimate objective in roads is the prevention of damage or failure of the road surface and subgrade by the...
A method is described to determine the distribution of the bending stresses in a wood beam when some of these stresses exceed the proportional limit. This is used to calculate the position of the neutral axis and the bending strength of some Douglas-fir beams. The calculated values agreed with the...
An anemia of juvenile chinook salmon (Oncorhynchus tshawytscha) is described and stages of development separated by recognizable syndromes. A vitamin E-deficient diet of low rancidity produced a severe microcytic anemia with strong immature red cell response and granulocytosis occurring 2 to 4 weeks before a drop in hemoglobin and hematocrit...
Part I. To aid in the management of the Tillamook Bay commercial salmon fishery, a tagging program was conducted on the salmon and steelhead trout runs in 1953. General migration behavior, the minimum length of time the fish remained in the fishery, population sizes, and fishing mortalities were determined from...
Clatsop Beaches, characterized by flat beach-face slope (1:70) and small sandsize (0.2 mm.), have supported commercial and recreational fisheries for the razor clam (Siliqua patula) for many years. Tracing the linear growth of two year classes through more than one year following set led to a validation of the ring...
The Oregon Fish Commission and Washington Department of Fisheries conducted a cooperative winter steelhead trout (Salmo gairdneri) tagging program on the Columbia River during the winters of 1954-55 and 1955-56. Objectives of the program were: (1) to obtain information on the timing of the various segments of the run; (2)...
ENTOMOLOGISTS, BOTANISTS, and AGRICULTURISTS all
have occasion to concern themselves with bees. The en-tomologist is fascinated by their complex behavior pat-terns, the botanist needs to evaluate their significance infloral biology, and the agriculturist must take them into account as vital factors in crop production. Finally, the apiculturist often wishes to...
The problem of this thesis is the existence of an anomalous manorial landscape in northern Fauquier County, Virginia. The county is about 45 miles southwest of Washington, D. C. The thesis seeks to develop a hypothesis to explain the existence of this landscape so different from surrounding areas in a...
