– The size segregation of granular materials in a vibrating container is investigated using Molecular Dynamics. We find that the rising of larger particles is accompanied by the existence of convection cells even in the case of the lowest possible frequencies. The convection can, however, also be triggered by the larger particle itself. The possibility of rising through this mechanism strongly ...

about 3 decades ago cd6 identified as one of the first antigens expresses on the majority of t cells and a subset of b cells. cd6 regulates cellular adhesion migration across the endothelial and epithelial cells. in recent years researches indicate its role in pathogenesis of autoimmune diseases. many researches have been done in recent years to block cd6 by cd6 mono clonal antibodies, ior-t1 a...
