a two-dimensional (2d) single particle model for the copolymerization of propylene-ethylene with heterogeneous ziegler-natta catalyst is developed. the model accounts for the effects of the initial shape of the catalyst and carck/ pore patterns on the copolymer composition, polymerization rate and the average molecular weight properties. the spherical and oblate ellipsoidal shapes of catalyst p...

purpose: neuromyelitis opitca (nmo) is an autoimmune disease that relates to deposition of anti-aquaporin-4 (aqp4) igg in the central nervous system (cns). however, called seronegative nmo when patients are negative for aqp4 antibody. nevertheless, nmo is most probably an antibody mediated disease. the aim of this study was to assess the association between seronegative nmo disease and variatio...
