My recent research work has focused on numerous problems in Complex Analysis of Several Variables which are also related to questions in non-linear analysis, partial differential equations, differential geometry and classical dynamics. More specifically, I have been working on the following topics: (1). Normal form theory and holomorphic equivalence problem of real submanifolds in a complex man...

conclusions p. aeruginosa and s. marcescens can be good candidates for the detoxification of cr (vi) in soltan abad river. results the results indicated that pseudomonas aeruginosa and serratia marcescens were the most resistant bacteria with mics of 200 and 150 mg/l, respectively. both bacteria completely reduced 25 and 50 mg/l of cr (vi) in 36 hours and 48 hours, respectively. the growth rate...

We show that 1-quasiconformal mappings on Goursat groups are CR or anti-CR mappings. This can reduce the determination of 1-quasiconformal mappings to the determination of CR automorphisms of CR manifolds, which is a fundamental problem in the theory of several complex variables.

We give a holomorphic extension result from non generic CR submanifold of C of positive CR dimension. We consider N a non generic CR submanifold given by N = {N, h(N)} where N is a generic submanifold of some C and h is a CR map from N into C. We prove that if N is a hypersurface then any CR distribution on N extends holomorphically to a complex transversal wedge, we then generalize this result...

In aqueous H2SO4 media, the chromic acid oxidation of D-galactose in the presence and absence of 2,2 ́ bipyridine (bpy) has been carried out under the conditions, [D-galactose]T >> [Cr(VI)]T at different temperatures. The monomeric species of Cr (VI) has been found to be kinetically active in the absence of bpy whereas in the bpy-catalysed path, the Cr(VI) -bpy complex has been suggested as the ...

The synthesis, characterization, and reactivity of a chromium(0) complex bearing an amine-borane moiety (η(6)-C(6)H(5)CH(2)NMe(2)·BH(3))Cr(CO)(3) (2) is reported. Photolysis of complex 2 results in the elimination of a CO ligand followed by the formation of an intramolecular σ-borane complex (η(1)-(η(6)-C(6)H(5)CH(2)NMe(2)·BH(2)-H))Cr(CO)(2) (3). This species was characterized in solution by NM...

Cr-spinel [(Mg, Fe2+)(Cr, Al, Fe3+)2O4)] is a common mineral in the ultramafic core of Duke Island complex southeastern Alaska, US. grains with an unmixed texture have been observed dunite and wehrlite complex. Inhomogeneous ratio Cr/(Al + Cr Fe3+) <0.37 prominent dunite. The inhomogeneous consists two completely different compositions: Al-rich Cr-spinel, Fe3+-rich wide range content (from 1...
