Riparian forest buffers can improve stream water quality, provided they intercept and remove contaminants from surface runoff and/or shallow groundwater. Soils, topography, hydrology, and surficial geology determine the capability of forest buffers to intercept and treat these flows. This paper describes landscape analysis techniques for identifying and mapping locations where forest buffers ca...

This paper advocates the placement of Architecturally Visible Communication (AVC) buffers between adjacent cores in MPSoCs to provide highthroughput communication for streaming applications. Producer/consumer relationships map poorly onto cache-based MPSoCs. Instead, we instantiate application specific AVC buffers on top of a distributed consistent and coherent cachebased system with shared mai...

Measurments with combination pH electrodes of the pH of the dilute buffers used in a commercial kit (CEA-Roche) for assay of carcinoembryonic antigen resulted in pH values 0.1 to 0.3 unit lower than pH values measured on an electrode system with a capillary junction. If the pH values of these buffers were adjusted, based on such measurements, an error in the assay of 0.2 to 0.6 ng/ml in the 1.5...

Riparian Management Systems (RiMS) have been proposed to minimize the impacts of agricultural production and improve water quality in Iowa in the Midwestern USA. As part of RiMS, multispecies riparian buffers have been shown to decrease nutrient, pesticide, and sediment concentrations in runoff from adjacent crop fields. However, their effect on nutrients and pesticides moving in groundwater be...

Mucosal and parenteral immunizations elicit qualitatively distinct immune responses, and there is evidence that mucosal immunization can skew the balance of T helper 1 and T helper 2 responses. However, a clear picture of the effect of the route of infection on the balance of the T helper responses has not yet emerged. Our laboratory previously demonstrated that oral reovirus infection elicits ...

The murine model of leishmaniosis is a prototypic example for the critical role played by T helper cells in immunity to pathogens. Cytokines, such as interleukin-12 and interleukin-4, are the major regulatory factors for differentiation of naive T helper cells into T helper 1 and T helper 2 cells, respectively. T helper 1 cells, which are cellular immune mechanisms involving gamma interferon pr...

This survey covers the general idea behind helper threads and the major ways in which they are implemented. The first section covers parallel helper threads and the issues crucial to their role in improving performance. The following sections cover the implementations of parallel helper threads, focusing on SMT processor based implementations and adapted superscalar processor based implementati...
