Water vapor transport in the vicinity of imbibing saline plumes: Homogeneous and layered unsaturated porous media

Creator:: Weisbrod, Noam, Niemet, Michael R., McGinnis, Thomas, and Selker, John S.
Abstract:: Water vapor transport in the vicinity of imbibing saline solutions was investigated in two-dimensional (2-D) chambers using a light transmission technique. Concentrated NaNO3 solutions (brines) were applied as point sources to the surface of homogenous packs of prewetted silica sand for four different sand grades. The same solutions were applied...

Relationships between gas-liquid interfacial surface area, liquid saturation, and light transmission in variably saturated porous media

Creator:: Niemet, Michael R., Rockhold, Mark L., Weisbrod, Noam, and Selker, John S.
Abstract:: Liquid saturation and gas-liquid interfacial area are important parameters for evaluating the transport and fate of contaminants in unsaturated subsurface environments. Recent findings indicate that interfacial surface area controls the relative degree of transmitted light in laboratory systems containing translucent porous media. Equations are derived to estimate the specific gas-liquid...

Effective Darcy-scale contact angles in porous media imbibing solutions of various surface tensions

Creator:: Weisbrod, Noam, McGinnis, Thomas, Rockhold, Mark L., Niemet, Michael R., and Selker, John S.
Abstract:: Surface tensions of high-salinity solutions are significantly different from those of pure water. Our objective was to develop and test a methodology to determine whether these surface tension effects predictably alter imbibition into dry and moist porous media. Static and dynamic experiments were performed using four grades of quartz sand...

Bacterio-opsin gene overexpression fails to elevate fungal disease resistance in transgenic poplar (Populus)

Creator:: Mohamed, Rozi, Meilan, Richard, Ostry, Michael E., Michler, Charles H., and Strauss, Steven H.
Abstract:: Overexpression of the bacterio-opsin (bO) gene in tobacco had previously been shown to induce hypersensitiveresponse- like lesions, increase viral and bacterial disease resistance, and stimulate pathogenesis-related gene expression. To see if this gene enhanced resistance to fungal pathogens of poplar, we generated a total of 35 transgenic lines in two...

Optical scattering and backscattering by organic and inorganic particulates in U.S. coastal waters

Creator:: Snyder, William A., Arnone, Robert A., Davis, Curtiss O., Goode, Wesley, Gould, Richard W., Ladner, Sherwin, Lamela, Gia, Rhea, William J., Stavn, Robert, Sydor, Michael, and Weidemann, Allen
Abstract:: We present the results of a study of optical scattering and backscattering of particulates for three coastal sites that represent a wide range of optical properties that are found in U.S. near-shore waters. The 6000 scattering and backscattering spectra collected for this study can be well approximated by a power-law...

Christmas tree nutrient management guide : western Oregon and Washington [2009]

Creator:: Hart, John M. (John Mervyn), 1947-, Landgren, Chal G., Fletcher, Richard A., Bondi, Michael C., Whithrow-Robinson, Bradford A., Chastagner, Gary A., and Oregon State University. Extension Service
Abstract:: During the past 50 years, plantation Christmas tree production has grown in acreage and sophistication. Nitrogen applications with a tuna can have been replaced by precise, mechanized application of a wide array of nutrients and lime. Current nutrient management programs must focus on three concepts for success. This guide provides...

Growing Christmas trees in the Pacific Northwest

Creator:: Oregon State University. Extension Service, Washington State University. Extension, University of Idaho. Extension, Landgren, Chal G., Fletcher, Richard A., Bondi, Michael C., Barney, Danny L., Mahoney, Ronald Lynn, and Pacific Northwest Cooperative Extension
Abstract:: Christmas trees are an enduring holiday tradition. U.S. producers supply about 35 million trees annually. The past few decades have seen the Pacific Northwest’s rise to prominence as the leading Christmas-tree producing region in the United States. With a combined annual production estimated at more than 11 million trees, Oregon,...

Michael, Ferrare, Richard, Dunion, Jason P., Douglas, Michael, Cifelli, Robert, Chen, Gao, Browell, Edward V., and Anderson, Bruce
Abstract:: In 2006, NASA led a field campaign to investigate the factors that control the fate of African easterly waves (AEWs) moving westward into the tropical Atlantic Ocean. Aircraft and surface-based equipment were based on Cape Verde's islands, helping to fill some of the data void between Africa and the Caribbean....

N. (Anita Nina), Andrews, N. (Nick), Mertz, Chris, Chilton, Mike, and Weeks, Tom
Abstract:: Oregon has a rich history in the production of fruits, berries, vegetables, and ornamental crops; the state’s national and international reputation for delivering high-quality products is well-established and well-deserved. In the past, agriculture and forestry were the foundation of Oregon’s economy. Although other activities now are equal in size to...
