Fertility patterns in countries on the northern shore of the Mediterranean have lowest-low fertility and are very different from those in the South-East of the basin.

Some stochastic approaches to biological aging modeling are studied. We assume that an organism acquires a random resource at birth. Death occurs when the accumulated dam-age (wear) exceeds this initial value, modeled by the discrete or continuous random vari-ables. Another source of death of an...
