We propose a simple procedure for visualising the electron density changes (EDC) during chemical reaction, which is based on mapping of rectangular grid points stationary structure into (distorted) positions around atoms another structure. Specifically, small step along minimum energy pathway (MEP), displacement each point obtained as linear combination motion all atoms, with contribution from ...

small precipitation with temporal and spatial variation of rainfall is the main responsible factors on flood occurrence in arid and semi arid regions. floods in their regions usually contain high concentration of sediments which when they are deposited on the surface of lands, they change the properties of soils of the area. in this research, the effect of floodwater spreading on physic-chemica...
