The development of a gas-permeable-membrane-supported (GPMS) biofilm reactor for the combined anaerobic/aerobic treatment of polychlorinated biphenyls

Creator:: Polonsky, Jon D.
Abstract:: A continuous flow, gas-permeable-membrane-supported (GPMS) biofilm reactor was developed to facilitate the treatment of polychlorinated biphenyls (PCBs). The GPMS biofilm reactor consisted of a cylindrical glass vessel made up of three compartments: the gas, liquid and headspace compartments. A gas-permeable membrane separated the bottom gas compartment from the liquid compartment....

Turbulence structure within an inclined laboratory convection tank

Creator:: Nance, Jon D.
Abstract:: A baroclinic, convective mixed-layer was modeled, using water, in a laboratory convection tank identical to that used in the free convection study of Deardorff and Willis (1985). Baroclinicity and mean-flow shearing were achieved by tilting the tank by an angle of 1O⁰. The resulting mechanical-production rate of turbulence kinetic energy...

Production rates and residual stand impact for four skidding machines during overstory removal

Creator:: Seifert, Jon Carl William
Abstract:: This study compares production rates and costs for four ground skidding machines and for four harvesting treatments. The four machine types studied were a Caterpillar 060 crawler (060), Caterpillar 518 rubber tired skidder (RTS), FMC 200 CA (FMC), and International TD-8E crawler (TD-8E). Two treatments, conventional/whole tree and designated/tree length,...

Remote sensing methodology for bioenvironmental surveillance in the vicinity of the Boardman Coal-Fired Power Plant, Oregon

Creator:: Denkers, D. Scott
Abstract:: In 1979, the Geographic Applications Laboratory of the Department of Geography, Oregon State University, was retained by the Portland General Electric Company to form and supervise a program to monitor the bioenvironment in the vicinity of the Boardman Coal-Fired Power plant. This partially fulfills requirements of the Department of Energy...

Mapping the potential acidic deposition in southwestern California using ambient air concentrations of acid precursors

Creator:: Doherty, David D.
Abstract:: Attempts to map the distribution of acidic deposition have been inadequate, particularly in areas of seasonal or limited rainfall. Ambient air concentrations of acid precursors may be used to monitor and map the distribution of potential acidic deposition. A network of stations in California currently monitor these ambient air concentrations....

A global scale analysis of the spatiotemporal distribution of foliar biomass for 1988

Creator:: Pross, Derek D.
Abstract:: Many ecological systems follow a seasonal cycle affecting primary production,carbon flux, and vegetative gas emissions. The seasonal variation of ecological systems are both affected by and have effects upon climatic factors. A quantitative estimate of the seasonal variation of vegetation is required to characterize ecological systems and their interaction with...

Bioaugmentation of Pure and Enriched Cultures Fed Multiple Primary Substrates to Aerobically Cometabolize a Mixture of Chlorinated Solvents and 1,4-dioxane in Microcosms Containing Groundwater from a Department of Defense Site

Creator:: Laurance, Jon C.
Abstract:: Chlorinated solvents are common groundwater pollutants that often exist as mixtures resulting from the use of multiple solvents and their transformation into chlorinated daughter products. These sites are often co-contaminated with the solvent stabilizer 1,4-dioxane (1,4-D), which is not treated by traditional chlorinated solvent remediation techniques. Both 1,4-D and chlorinated...

Temperature-dependent development of strawberry root weevil Otiorhynchus ovatus (L.)

Creator:: Umble, Jon R.
Abstract:: The temperature-dependent development of pupae and adults of strawberry root weevil (SRW) Otiorhynchus ovatus (L.) was studied in strawberry (Fragaria x ananassa Duch. var. 'Totem'). The development of pupae and adults was investigated at constant temperatures from 3-33°C at 3°C intervals. Major emphasis was on the development of a weighted...

Apparel descriptions in catalogs and perceived risk associated with catalog purchases

Creator:: Gaal, Brigitte D.
Abstract:: The increasing popularity of catalog shopping has prompted many retailers to enter the market. Consequently, competition among catalog retailers has escalated. To maintain or expand their customer bases, catalog retailers must now find better ways to serve consumers. Many consumers are apprehensive to shop for apparel via catalog because they...

Biophysical spectral regionalization of the Pacific Northwest using Advanced Very High Resolution Radiometer Imagery

Creator:: Greninger, Jon F.
Abstract:: Satellite imagery has become an efficient and time effective tool that may aid in the development of regional terrestrial and aquatic resource management schemes. A methodology utilizing National Oceanic and Atmospheric Administration (NOAA) Advanced Very High Resolution Radiometer (AVHRR) imagery, 1.1 kilometer spatial resolution at nadir, was developed for delineating...
