To use the map locator to find map products use the search bar or drop a pin by double clicking on the map view. Map location pins dropped or searched for by address/place provide products within a 15 mile radius of specified location. Since, Most of the engineering colleges with autonomous status are using Relative Grading System in evaluating their student performance. Version 1 (pdf). Different elements have different "mobility" in the environment based on, their readiness to dissolve in water, their density, their ability to form compounds with other, elements and the acidity (pH) of the environment.
