in this paper we find sufficient conditions on primitive inverse topological semigroup s under which: the inversion inv : (h(s)) (h(s)) is continuous; we show that every topologically periodic countable compact primitive inverse topological semigroups with closed h-classes is topologically isomorphic to an orthogonal sum p i2= bi (gi) of topological brandt extensions bi (gi) of countably compac...

activated charcol phase loaded with 2-propylpiperidine-1-carbodithioate (ppcd) were synthesized based on chemical binding and physical adsorption approaches. the stability of a chemically modified ppcd especially in concentrated hydrochloric acid which was then used as a recycling and pre-concentration reagent for further uses of activated charcol immobilized ppcd. the application of this activ...

background : we investigated whether the c-819t snp of the ctla4 gene is associated with type 1 diabetes (t1d) for the egyptian population, a multi-ethnic group.  we determined if expression of the c-819t snp correlated with onset of t1d for egyptian children and the prevalence of this polymorphism with respect to gender. methods: the association of the c-819t snp in intron 1 of the ctla-4 gene...

In the title compound, [ReBr(C(27)H(27)NP(2))(CO)(3)], the Re(I) atom is octa-hedrally surrounded by three carbonyl ligands in a facial arrangement, a bromide ligand and the P,P'-bidentate ligand Bis(diphenyl-phosphino)propyl-amine. The compound exhibits substitutional disorder of the bromide ligand and the axial carbonyl ligand, with almost 50% occupancy for both Br amd CO [0.538 (4) and 0.462...
