When compared to the pure polyimide,the hybrid membranes showed higher separation properties for H_2,CO_2 and H_2O relative to N_2.The separation factors of the polyimide/SiO_2 hybrid membranes with 25(wt)% SiO_2 contents for H_2/N_2,CO_2/N_2 and H_2O/N_2 are 55.9,31.1 and 42.8,respectively.
Results Both CRP and GR% were significantly higher in the bacterial infection group than those in the viral infection group(P<0.01) and However,there was insignificantly difference in WBC between both the groups(P>0.05).
In the interesting case when the group is of Coxeter typeDn (n≥4) we use higher polarization operators introduced by Wallach.
In this paper, we prove three types of rigidity results related to CAT(-1) spaces, namely the rigidity of the isometric actions on CAT(-1) spaces under the commensurability subgroups, the higher rank lattices and certain ergodic cocycles.
Finitely generated profinitely dense free groups in higher rank semi-simple groups
More generally, we prove that if Γ is an irreducible arithmetic non-cocompact lattice in a higher rank group, then Γ containsf·g·p·d·f groups.
