The rapid population growth and related economic
growth of the Willamette Valley has resulted in a significant
reduction in air quality over the past several decades.
Within the Willamette Valley air ventilation is very poor and
therefore the airpo1lutton potential is one of the highest
in the United States. There...
This research paper is an analysis of the electric energy industry
in Mexico since its inception in 1879. The research is based entirely

Detailed phytosociological and physical data were gathered from six grass-fern balds in the Oregon Coast Range, Monmouth Peak, Grass Mountain, Prairie Peak, Roman Nose Mountain, Tyee Mountain, and Saddle Mountain. Panchromatic and color infrared air photography guided sampling within individual balds. The resultant floristic data was manipulated by a Braun-Blanquet...
Buffer strips have been proposed as a method for controlling temperature changes in streams adjacent to clear-cuttings. Nine small mountain streams in Oregon's Coast Range and Cascade Mountains were studied to determine the influence of buffer strips on water temperature. Timber volume in the strip, strip width, and canopy density...

This study compared two groups of home sewers in relation to
their sewing practices, perceived sewing competence, sex-role
concept, and selected demographic factors. A review of literature
indicated an increase in home sewing that began in the 1960's with

Local property-owning residents maintain high levels of interest
and awareness regarding a neighboring natural resource complex.
Factors, however, such as proximity, personal interests, use patterns
and economic considerations cause local inhabitants to have an

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...
A theoretical study of the heat and momentum transfer resulting
from a flow of power plant condenser effluent discharged vertically to
shallow, quiescent coastal receiving water is presented. The complete
partial differential equations governing steady, incompressible, turbulent

using finite-difference techniques...
Variances among individuals within populations are influenced by environmental and genetic factors. Utilizing quantitative genetic theory, environmental and genetic components of variance have been
compartmented for a variety of quantitative characters of the Pacific oyster, Crassostrea gigas.
A significant genetic component of variance in a quantitative attribute related to reproductive...
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...

Land management techniques are numerous and well known, but knowledge of where and how to use these techniques is often inadequate. Silvicultural methods used by foresters in the Pacific Northwest exemplifies this quandary. Silviculture largely consists of applying standard techniques to various forest stands. Classical silvicultural techniques are not universally...
The crawfish enterprise of South Louisiana is shown to haveexpanded as much as 18-fold since the 1950's. It is estimated(1973) that there are about 44,000 acres of managed crawfish ponds.Of the 334 ponds identified and mapped in the thesis, 231 are classedas open ponds, 45 as rice field ponds, and...
During the Colonial Period, in Mexico there was no rational
