    130130where S is the supersaturation, ''R'',,c,, the integral radius and G(T,p) a function of temperature and pressure considering heat conductivity and diffusion.
    131 Using this explicit approach the used timestep must fulfill a new criterion, since it is assumed that the supersaturation is constant during one timestep. The typical timescale is given by
