pores, a condition suf cient to state the de ciency of scaffold functionality.
Furthermore, the hydraulic conductivity and the local ow characteristics of
percolating clusters can be numerically evaluated by referring to multigrid
techniques, see for example, Fig. 16.11, or by adopting mean eld theories
of ow in porous medium, such as the Bruggeman effective medium theory
(Fokker, 2001) (also see e.g., an application for two-dimensional ows in
Scaraggi, 2012). The fractal dimensions of the micro-porosity of the per-
colating cluster ruling the cell-wall adhesion phenomena (see e.g., Gentile
et al. , 2010) can be also determined by referring to the box counting method
