Multifactorial Bases of Stroke After Cardiac Surgery To the Editor: We read with great interest the article by Gottesman et al1 dealing with one of the most devasting complications of cardiac surgery, perioperative stroke. The article analyzed the impact on outcomes of watershed stroke and the role of intraoperative hypoperfusion on its onset. Nevertheless, their report raises some concerns. Th...

Striving for long-term sustainability in catchments dominated by human activities requires development of interdisciplinary research methods to account for the interplay between environmental concerns and socio-economic pressures. In this study, we present an integrative analysis of the Lake Simcoe watershed, Ontario, Canada, as viewed from the perspective of a socio-ecological system. Key feat...

Watershed transform is considered to be an important technique in image segmentation. It is the method for image segmentation in the section of mathematical morphology. Work of watershed segmentation proceeds using the neighboring pixels. We present a critical review of several definitions of the watershed transform and the associated sequential algorithms, immersion models and therefore parall...

in agroforestry landscapes, land use, and the associated management practices exert strong impacts upon soil organic carbon stocks. data on the soil organic carbon were collected for different land-use types within a small watershed, el salado, located in lanjarón (se spain). eight land-use types namely: farmland planted in olive, almond, and cereals; forest with pinus halepensis mill. and pinu...

Cattle (Bos taurus) grazing on unimproved pastures can be a significant, yet often overlooked, source of pollutants to surface waters, especially when the cattle have unlimited access to streams in the pastures. Livestock exclusion from streams has been demonstrated to reduce sediment and possibly nutrient yield from streams draining pastures. The purpose of this study was to evaluate the effec...
