Sub-regional detention siting : a methodology using GIS

Creator:: Murdock, Carol L.
Abstract:: The Mt. Scott watershed in northern Clackamas County, Oregon is an urban watershed that lies inside the Portland metropolitan urban growth boundary. Urbanization of the watershed began in the early 1970s and has recently accelerated. A landscape level analysis of the urbanization process was combined with the results of a...

Farm level response to agricultural effluent control strategies : the case of the Willamette Valley

Creator:: Taylor, Michael L. (Michael Lester), 1960-
Abstract:: Changes in the structure of the U.S. agricultural industry since World War II have transformed it into a highly productive component of the domestic economy. But these changes have not occurred without indirect costs. For example, the reliance on agricultural chemicals has produced environmental effects causing growing concern. In addition,...

Estimating absence

Creator:: Kincaid, Thomas M.
Abstract:: The problem addressed is absence of a class of objects in a finite set of objects, which is investigated by considering absence of a species and absence in relation to a threshold. Regarding absence of a species, we demonstrate that the assessed probability of absence of the class of objects...

Assessment of exposure and response to atmospherically-derived contaminants in U.S. Arctic freshwater fish

Creator:: Allen-Gil, Susan M.
Abstract:: The Arctic has long been considered to be a pristine environment, far from population centers and pollution sources. The detection of synthetic organochlorine compounds in various elements of the Arctic food web has confirmed the global dispersion of pollutants, particularly of persistent compounds such as organochlorines and heavy metals. Levels...

Diagnostics for the evaluation of spatial linear models

Creator:: Thompson, Caryn M. (Caryn Marie)
Abstract:: Geostatistical linear interpolation procedures such as kriging require knowledge of the covariance structure of the spatial process under investigation. In practice, the covariance of the process is unknown, and must be estimated from the available data. As the quality of the resulting predictions, and associated mean square prediction errors, depends...

Molecular fingerprinting, rDNA internal transcribed spacer sequence, and karyotype analysis of Ustilago hordei and related smut fungi

Creator:: Abdennadher, Mourad
Abstract:: Inbreeding of the avirulent physiologic race 8 strains of Ustilago hordei was purported to have increased its pathogenicity in a stepwise manner that led to a highly pathogenic race, designated race 14. The analysis of electrophoretic karyotypes and restriction fragment length polymorphism profiles detected with a telomere-specific probe (TelomereRFLP) in...

The rainbow hydrothermal plume, 36°15'N, MAR

Creator:: German, C. R., Klinkhammer, Gary P., and Rudnicki, M. D.
Abstract:: The Rainbow hydrothermal plume was discovered during a recent geophysical survey along 200km of the Mid-Atlantic Ridge (MAR), SW of the Azores Triple Junction, in which at least seven new sites of hydrothermal activity were identified. Here, we present the first hydrographic study of the Rainbow plume, 36° 15'N, the...

Upper ocean thermohaline fields near 2°S, 156°E, during the Tropical Ocean-Global Atmosphere - Coupled Ocean-Atmosphere Response Experiment, November 1992 to February 1993

Creator:: Huyer, Adriana, 1945-, Kosro, P. Michael, 1951-, Lukas, Roger, and Hacker, Peter
Abstract:: Zonal and meridional Seasoar sections centered at 1°50’S, 156°06’E were repeated >30 times in three 20-day periods between November 13, 1992, and February 15, 1993. Both sections were 130 km long, and sampling depth was 0–280 m, with a vertical resolution of ~2 dbar (2 x 104 Pa) and a...

Effect of nutrition on reproductive performance of young female mink

Creator:: Polonen, Ilpo Juhani
Abstract:: Two distinct experiments were conducted. Experiment 1 was conducted to investigate the effects of nutritional conditioning and flushing as a means of improving reproductive performance of female mink. In Exp. 2, vegetable oil and corn syrup were fed during lactation to ascertain whether this nutritional regimen would improve growth of...

Long-term effects of tillage, nitrogen, and rainfall on winter wheat yields

Creator:: Camara, Kelli Marie
Abstract:: Winter wheat is commonly grown in dryland cropping systems in the Pacific Northwest region of semi-arid eastern Oregon. For agronomic, economic, and environmental reasons, it is important to understand the long-term sustainability of such dryland systems. The objective of this study was to evaluate the long-term effects of tillage, nitrogen...
