Nhomo + Nhetero = 5.28*10^21*exp[-54.15/(ln(S))^2] + 7.83*10^12*exp[-2.063/(ln(S))^2]

where S stands for supersaturation ratio: S=c/cs
(when S=1 solution is saturated, S>1 supersaturated)

> when S=1 solution is saturated...

...and nucleation rate is of course zero; it means that given relation applies for S>1 only (otherwise would be division by zero; non-zero values for S<1 also have no physical sense and then N=0 too)
