20. Assuming a disclination strength s = 1 / 2 is plausible because it is the only strictly topologically stable type of disclination in a nematic. It is a possibility that the disclinations could be of strength s = 1 (but certainly not higher than that). In considering δ, the strength enters into both the energy and the friction contributions, and so the only place where the difference might be noticed is in the disclination-core term in Eq.. This modification has a minor effect on the estimates presented here.
