Query: Different approaches to describe depletion regions in first order phase
  transition kinetics   The theory of nucleation with depletion zones is discussed. The approach of
stochastic effects of solitary droplet is analyzed. The negative features of a
solution with fixed boundary are outlined. A new solution with effective fixed
boundary is proposed. All main stochastic characteristics are obtained.
