Despite increased attention and demand for the adoption of agroforestry practices throughout the world, rigorous long-term scientific studies confirming environmental benefits from the use of agroforestry practices are limited. The objective was to examine nonpoint-source pollution (NPSP) reduction as influenced by agroforestry buffers in watersheds under grazing and row crop management. The gr...

The correctness of applications that perform asynchronous message passing typically relies on the underlying hardware having a sufficient amount of memory (message buffers) to hold all undelivered messages—such applications may deadlock when executed on a system with an insufficient number of message buffers. Thus, determining the minimum number of buffers that an application needs to prevent d...

Given a spatial network, a spatial neighbourhood, a collection of activities, a constant buffer area and a number of clusters to identify (k), the problem of spatial activity summarization using constant area buffers is to choose the user defined k constant area buffers which maximizes the number of activities covered. Spatial activity summarization is an important societal problem and has been...

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...
