The report integrates a survey of organic farmers in Oregon, Washington, and Idaho; conversations with focus groups made up of southern Oregon organic farmers and organic farming stakeholders; and interviews with Oregon State University organic agriculture researchers. It highlights research, education, and policy issues identified by organic farmers and researchers....
This thesis reports a portion of a general ecological study of
a stream under conditions of controlled flow and low levels of organic
enrichment. It is concerned with the effects of experimental variations
of light intensity and concentration of soluble organic enrichment
imposed on seasonal variations of temperature and total...
The paper is a study of (i) the realization of the gyrator,
(ii) active filter synthesis using gyrator.
Several realization methods of the gyrator are summarized.
A practical gyrator composed of two operational amplifiers was built
and tested. The experimental results are shown. Two RC-gyrator
synthesis techniques are derived and...
This study evaluates the feasibility of retrofitting a rotary
dryer to a hog fuel boiler, using the boiler exhaust gases as the
drying medium.
Two simulation models were developed. As substantiated by experimental
measurement of existing boiler/dryer systems, each model
accurately predicts system performance given site-specific parameters
such as boiler...
The major considerations for acquiring and using a
geographic information system (G..I.S.) for regional or national
geographical research and analysis are examined in this paper.
After defining what a G.I.S. is, some of the more practical and
useful functions of a G.I.S. in day-to--day geographical work are
outlined. Finally, the...
The purpose of this work was to develop a dynamic partial order model of II electrolyte solutions which avoids inconsistencies present in the Debye-1-Iuckel and 1n related theories. It is shown that our results are consistent with activity coefficient data in aqueous electrolyte solutions. The main features of our work...
