A novel series of Bis-Schiff bases of pyrazoles 9–24 were synthesized by the direct condensation of 5-aminopyrazoles 4a–d with dialdehydes 8a–d in ethanol. The newly synthesized Bis-Schiff bases of pyrazoles 9–24 were characterized and confir

In the present work an aero-elastic model is presented to study flutter and divergence of isotropic plate wings. A finite element model is subsequently developed to apply the theoretical model and predict the performance of plate wings. A divergence
