Beaches, as deposits of unconsolidated material at the land/water interface, are open systems where input and output items constitute sediment budget. Beach evolution depends on difference between input/output to system; if positive beach advances, negative retreats. Is it possible that this is zero stable? The various processes responsible for in any system here considered by taking examples f...

Here is presented a new exact solution of Ice dynamics in Glaciers in terms of viscousplastic theory of movements, for 2-dimensional case. In general case, 2-D solution of Ice dynamics could be classified as Riccati’s type. Due to a very special character of Riccati’s type equation, it’s general solution is proved to have a proper gap of components of such a solution. It means a possibility of ...

Based on the material flow analysis method, green development index system of industrial park was constructed. By using PSR model, 13 indexes were divided into pressure layer, state layer and response standardized, weight distribution synthesis. The level 5 grades combined with factors. results show that energy consumption per unit output a stainless-steel is 0.7116 tons standard coal million y...
