✦ Synopsis

A nucleation and ,srowth model is proposed to explain NMR observations of the reorder+ of a nematic-cholesteric lïquid crysta1 mixture. The model involves the growth of three dïmensional reordered regions. It predicts a time dependence involving expl-Ar?l) with N = 2.5. Previous measurements fit the model very well except for an unexplained time delay t0; i.e.

the data has a time dependence involving exp[ -A(t -top]

with N = 2.5.

## Abstract In [3], L. Berselli showed that the regularity criterion ∇**u** ∈ (0, __T__; **L**^__q__^ (Ω)), for some __q__ ∈ (3/2, + ∞], implies regularity for the weak solutions of the Navier–Stokes equations, being **u** the velocity field. In this work, we prove that such hypothesis on the velo
