In this paper we present a particle-based method for large scale long time progressive simulation of terrain erosion containing wet granular particles. The wetting process and the propagation through granular material is based on defining the wetness value for each particle representing the amount of water absorbed by granular particles and stored between them, as was originally proposed by Run...

The technique of farming two or more crops in the same field at time is known as intercropping. It has been practiced for decades. provides a number benefits, including efficient and effective resource utilization, less soil erosion, increased yield output on limited cultivated field, risk reduction smallholder farmers, higher income per unit work during times labor scarcity. Intercropping legu...

For development of a comprehensive sediment management plan, it is crucial to categorize watersheds on the basis soil erosion hotspot areas extend useful life water bodies (e.g., Gidam reservoir). The goal this study was assess surface potential and identify Gidabo watershed in Ethiopia using Soil Water Assessment Tool (SWAT) model. SUFI-2 (Sequential Uncertainty Fitting Version 2) program used...

We characterize the perimeter-minimizing double bubbles on all flat two-tori and, as corollaries, on the flat infinite cylinder and the flat infinite strip with free boundary. Specifically, we show that there are five distinct types of minimizers on flat two-tori, depending on the areas to be enclosed.

We review the use of elemental depletions in determining the composition of interstellar dust and present a new interpretation of the elemental depletion patterns for the dust forming elements in a range of diffuse cloud types. We discuss this within the context of dust processing in the ISM and show that Si and Mg are selectively eroded from dust, with respect to Fe, as expected for a sputteri...

introduction: cholestasis is impairment of normal bile excretion into the duodenum and classified as mechanical and non mechanical cholestasis. mechanical cholestasis presents with increase in bile duct diameter or obstruction in bile duct in an ercp. cholestasis leads to different complications. one of these complications is mucosal peptic erosion leading to gastrointestinal bleeding, perforat...

Lignin is deposited in precise patterns in some cell types. Two recent papers provide insights into how this is achieved in the Casparian strip of the root endodermis where a discrete band of lignin is crucial to regulating the passage of water and solutes.
