of major elements and Zr,V,Ti and Y.Bulk densities as well as Ti,Zr and V concentrations were used to estimate the strain factors and mass balance equations were used to quantify the net result of pedogenic weathering,i.e.elemental loss and gain.The results of clay content and pedogenic ...

For more general mass matrices, such as a general quadrilateral element (Chapter 7), or elements that involve higher order interpolation polynomials, how to lump the mass to the nodes is not very clear. One of the approaches commonly used for such elements is the row sum method [1,9]. In...
In the end, we have shown that the combined approach consisting of RDE experiments and finite elements modelling providing a tool to unravel of the structure of the diffusion and convection boundary layers both in dynamic and stationary conditions....
