Creator:: Rhodes, Albert N.
Abstract:: This study examined the effects of Roundup [N-(phosphonomethyl) glycine] and N-Serve [2-chloro-6- (trichloromethyl) pyridine] on nitrifying organisms in static batch, perfusion soil columns, and a new continuous-flow soil column system. The continuous-flow method is new to nitrification studies and was shown to produce greater nitrifier activity than either static batch...

Creator:: Brooker, Deborah L.
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...

Full Text:: effort to measure the effect of UV-B radiation on the colonization of new substrates by benthic diatoms

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...
