We show that various notions of local homogeneity for CR-manifolds are equivalent. In particular, if germs at any two points of a CR-manifold are CR-equivalent, there exists a transitive local Lie group action by CR-automorphisms near every point.

We study a CR analogue of the Ahlfors derivative for conformal immersions Stowe that generalizes Schwarzian studied earlier by second-named author. This notion possesses several important properties similar to those counterpart and provides new invariant spherically equivalent maps from strictly pseudoconvex manifolds into sphere. The is computable distinguishes many well-known sphere maps. In ...

the reaction of an equivalent of 2- mercaptoethyl ammonium chloride with an equivalent of 2,6-diformyl -4- methyl phenol produced monoamine which was reacted with half equivalent of 1,2-diamine ethane to produce ethylene-bis-6-(2-mercapto-ethyl-imine)-methyl -4- methyl phenol [h4l]. the ligand was reacted with metal ions[cr(iii), mn(ii), fe(ii), co(ii), ni(ii), cu(ii), zn(ii), cd(ii), and hg(ii...

The articles [12], [8], [13], [11], [14], [5], [4], [9], [16], [1], [2], [7], and [6] provide the notation and terminology for this paper. Let X be a set and let Y be a subset of 2X . Then ⋃ Y is a subset of X . In this article we present several logical schemes. The scheme DenestFraenkel deals with a non empty set A , a non empty set B, a unary functor F yielding a set, a unary functor G yield...

Chromium trispicolinate (CrPic) is a popular dietary supplement that is not regulated by the Food and Drug Administration. We are using this compound as a bio-available model to explore the role of Cr(III) in Cr(VI)-induced cancers. The ability of CrPic to cause mutations at the hypoxanthine (guanine) phosphoribosyltransferase (hprt) locus of CHO AA8 cells has been measured after a 48 h exposur...

This paper demostrates a method for analysing almost CR geometries (H, J), by uniquely defining a partially integrable structure (H,K) from the same data. Thus two almost CR geometries (H,J) and (H ′, J ′) are equivalent if and and only if they generate isomorphic induced partially integrable CR geometries (H,K) and (H ′, K′), and the set of CR morphisms between these spaces contains an element...

BACKGROUND We investigated the patterns and predictors of recurrence and survival in cryptogenic non-B, non-C, non-alcoholic hepatocellular carcinoma (CR-HCC). We compared the findings with those hepatitis virus B (B) and hepatitis virus C (C)-HCC. CR-HCC does not include HCC developed on NASH. METHODS From 1990 to 2011, of 676 patients who underwent primary curative liver resection as initia...

Results of the experiments on board Cosmos-2044 (Biosatellite 9) are presented. Various nuclear track detectors (NTD) (dielectric, AgCl-based, nuclear emulsions) were used to obtain the LET spectra inside and outside the satellite. The spectra from the different NTDs have proved to be in general agreement. The results of LET spectra calculations using two different models are also presented....

In this paper, we give a characterization of the finite multiplicity of a CR mapping between real analytic hypersurfaces. The finite multiplicity of a CR mapping was defined algebraically by Baouendi and Rothschild in [BR1] (see the definition below). We will prove that under certain conditions on hypersurfaces the finite multiplicity of a CR mapping is equivalent to that the preimage of the ma...
