Let ⌫ be a finite connected regular graph with vertex set V ⌫, and let G be a subgroup of its automorphism group Aut ⌫. Then ⌫ is said to be G-locally primiti¨e if, for each vertex ␣ , the stabilizer G is primitive on the set of vertices adjacent to ␣ ␣. In this paper we assume that G is an almost s
This work reports a comparative study of the catalytic behaviour for a series of metallocenes derived from Ti, Zr, Hf and Nb, which after activation with methylaluminoxane can polymerize ethylene. Results show that the Zr metallocene with a -(CH3)2Si-bridge presents the highest activity, and the met
