Query: Isotope uptake dynamics in the Ostwald ripening model of
  recrystallization   The article is withdrawn since we decided not to publish it in the present
form but to divide it in two parts. One of these parts concerns the
mathematical aspects of Return Radius calculation and the rewritten article is
already available arXiv:1201.4492 The second part will discuss the modelling of
the Isotope Uptake and is still in preparation
