Creator:: Boersma, L., Lindstrom, F. T., and McFarlane, Craig, 1936-
Abstract:: Uptake, in-plant transport, and local accumulation of organic chemicals by plants are influenced by plant characteristics, properties of the chemical and the soil, and by environmental conditions. Evaluations of plant contamination required by regulatory agencies cannot be made experimentally for the many thousands of xenobiotic chemicals in existence or being...

Creator:: Oregon State University. Agricultural Experiment Station, Lindstrom, F. T., Boersma, L., and Yingjajaval, Suntaree
Abstract:: CTSPAC is a mathematical model for coupled transport of water, solutes, and thermal energy in the soil-plant-atmosphere continuum. The mathematical structure consists of coupling a model for transport through soil (soil submodel) to one for xylem and phloem transport (plant submodel). The modeling approach is based on discrete space conceptualization...

Creator:: Ives, Edward Ewing., Youmans, Russell C., and Oregon State University. Agricultural Experiment Station
Abstract:: This bulletin has two intended uses: 1) to report the findings of a small rural region input-output model estimated for Tillamook County, Oregon, and 2) to explain how an input-output model can be interpreted and used. The report was written with a minimum of technical jargon and mathematics to help...

Creator:: Rompa, William J.
Abstract:: About 300 local businesses and industries in Clatsop County were interviewed and asked questions about their sales and purchases. The information they supplied from this survey was used to develop the economic model. This publication describes some of the findings of the study and how the model can be used...
