ABSTRACF: Bench terracing's effect on erosion, soil characteristics, crop yields, and cropping area and socioeconomic factors that affect farmers views and use of bench terraces were evaluated in the Kerinci uplands of Sumatra , Indonesia. Bench terraces reduced soil loss 70% (P<0.05) on enclosed runoff plots in comparison to unterraced fields under the same cropping pattern. Erosion under benc...
Abstract This study was conducted to simulate the sediment yield and evaluate best management practices (BMPs) for control in Azuari watershed, Upper Blue Nile basin, Ethiopia using Soil Water Assessment Tool (SWAT) model. As inputs model, 30 years (1991–2020) of daily values meteorological data were used. For model simulation, stream flow collected periods from 1988 2012. The area delineated i...
Proteus mirabilis colonies exhibit striking geometric regularity. Basic microbiological methods and imaging techniques were used to measure periodic macroscopic events in swarm colony morphogenesis. We distinguished three initial phases (lag phase, first swarming phase, and first consolidation phase) followed by repeating cycles of subsequent swarming plus consolidation phases. Each Proteus swa...
