Heritability of anthropological characters.

Abstract

Silica hydrogels show fractal properties corresponding with DLCAA or RLCCA. During aging silica is redistributed, resulting in reinforcement of the tenuous structure and only slightly disturbing fractal geometry. In zeolitic precursors no mass- fractals are present, but SAXS spectra show strong indications for the presence of surface-fractals. Computer simulations do confirm the experimental results
