Norbert Wiener and the growth of negative feedback in scientific explanation : with a proposed research program of "cybernetic analysis"

Creator:: Hellman, Walter Daniel
Abstract:: Negative feedback has become ubiquitous in science both as a technique and as a conceptual tool. As a technique, negative feedback has a long history; devices based in its use were made in antiquity. It has only been during the last century, however, that rigorous quantitiative methods have become associated...

Economic optimization of irrigation

Creator:: English, Marshall J., Nelson, A. Gene, Nakamura, Brian C., Nielsen, Kim C., and Nuss, Gary S.
Abstract:: The research effort described in this report explores the whole question of optimization of irrigation system design, planning and operations. Optimum irrigation practices, in theory, may involve some degree of deficit irrigation (deliberate under-irrigation of crops), hence the focus of this research was the use of deficit irrigation under practical...

First-year performance of 1-0 containerized Douglas-fir seedlings on droughty sites in southwestern Oregon

Creator:: Hobbs, Stephen D., Oregon State University. Forest Research Laboratory, Byars, R. H ., Henneman, D. C., and Frost, C. R.
Abstract:: The effects of artificial shading and aspect on the performance of 1-0 container-grown Douglas-fir seedlings were evaluated 1 year after outplanting on four different aspects in southwest Oregon. The test areas, all characterized by steep slopes and shallow, skeletal soils with a surface mantle of loose rock and logging slash,...

Environment and shoot growth of woody plants

Creator:: Lavender, Denis P. and Oregon State University. Forest Research Laboratory
Abstract:: Perennial woody plants have a complex annual cycle keyed to the environment. Temperate plants have an annual dormant period commonly broken by exposure to low temperatures, although daily photoperiods of 16 hours or longer may partially substitute for the chilling. Shoot growth in the spring is normally stimulated by rising...

Douglas-fir tussock moth adult male survey north Idaho and western Montana, 1982

Creator:: Dewey, Jerald E., Livingston, R. Ladd, Kohler, Steve, and United States. Forest Service. Northern Region. Cooperative Forestry & Pest Management
Abstract:: Douglas-fir tussock moth populations are monitored annually in northern Idaho and western Montana to insure early detection of changes from endemic to outbreak population levels. Adult moth trapping in 1982 was intensified and expanded into additional areas from 1981 because of concern that with each passing year the probability of...

Biological and economic feasibility of pruning and excising white pines for blister rust control

Creator:: Hagle, Susan K. and Grasham, John L.
Abstract:: White pine plantations which were established in 1968 on 88 acres of the Palouse Ranger District, Clearwater National Forest, were treated by pruning and canker excision to remove lethal white pine blister rust cankers. The success rate 15 months after treatment was 98 percent for pruning and 81 percent for...
