The effect of portal diversion by ameroid constriction was studied in the carcinogenic process in the rat after initiation of foci by diethylnitrosamine and after the establishment of putative preneoplastic nodules. Portal diversion or portal diversion plus partial hepatectomy did not act to promote

✦ Synopsis
The sequence of conformatlons a cluster assumes as it grows from a trimer into a thirteen-atom aggregrate under a given model potential has been studied. The model potential proposed is a construction composed of a van der Waals pairwise term and a three-body term composed of the triple dipole contribution and the exchange overlap contribution.
A parametric study of the thermodynamically preferred structures is given. After reaching a boundary between regions in the parameter space, equilibrium mixtures of isomers with different packings are obtained. The normal frequency spectrum is given for clusters up to thirteen atoms.
