The dominant nucleation mode

To identify the dominant rate-controlling nucleation mode in the compressive-yield experiments of Kazmierczak et al. (2005) on PE with different lamella thicknesses, the flow stresses for the three modes A, B, and C are determined by using eqs. (9.8), (9.14), (9.16), (9.22), and (9.23) to obtain 

The specific A for the different modes are obtained as follows. We have
