Query: On the blow up criterion of 3D-NSE in Sobolev-Gevrey spaces   In \cite{JB1}, Benameur proved a blow-up result of the non regular solution
of $(NSE)$ in the Sobolev-Gevrey spaces. In this paper we improve this result,
precisely we give an exponential type explosion in Sobolev-Gevrey spaces with
less regularity on the initial condition. Fourier analysis is used.
