Creator:: Robbins, Scott Hill
Abstract:: The effect of pressure trunk injections of K₂HPO₄, and K₂SO₄. solutions on the mineral content, growth, yield and fruit quality of sweet cherry and mineral content of prune were investigated. A complimentary study presented in Appendix 1, was conducted to evaluate the short term effectiveness of K soil amendments, mulching...

Abstract:: Global atmospheric pollution from chlorofluorocarbons has the potential of causing significant reductions in the concentrations of stratospheric ozone. If the production of chlorofluorocarbons were to continue into the future at the rate prevalent in 1977, the steady state reduction in total global ozone could be between five percent to ten...

Creator:: Mitchell, Becky
Abstract:: Take-all root rot (caused by Gaeumannomyces graminis var. tritici, Ggt) is one of the major diseases limiting winter wheat yields in western Oregon. Losses caused by take-all (TA) can be significantly reduced through crop management and fertilization practices. Results from field experiments in western Oregon show that the use of...

Creator:: Brooker, Deborah L., Worrest, Robert C.,, and Oregon State University
Abstract:: Artificial substrates colonized by diatoms from Yaquina Estuary, Oregon, were exposed to solar visible radiation and three levels of ultraviolet radiation (UV-B, 290-320 nm). Flow-through microcosms were constructed inside a glasshouse to serve as chambers for the artificial substrates. The artificial substrates were sampled during three spring/summer experiments. Chlorophyll a...

Creator:: George, Thomas L.
Abstract:: A model is developed that allows the prediction of the stress-strain distribution in a mixed carbide sphere pac fuel pin during irradiation. The model is coupled with a previously developed model for the thermal behavior of the pin. The one-dimensional (radial at various axial locations) solution is for quasi-steady pin...

Creator:: Behrenfeld, Mike J.
Abstract:: Anthropogenic releases of trace gases into the atmosphere are causing a decrease in stratospheric ozone concentrations and a subsequent increase in solar ultraviolet-B (UV-B)(280-320 nm) radiation reaching the earth's surface. The objective of this study was to determine the acute effects of enhanced UV-B radiation on the primary production of...
