A very limited range of products was available in the 1930s, and natural products such as morphine, digitalis and quinine were very important. Relatively few synthetic compounds, such as aspirin and the barbiturates, were available. The war itself pr

Thus the public’s concept of chemicals, although admittedly based on a limited understanding of them, was a very fa

Nonlinear Dynamic Buckling and Stability of Autonomous Dissipative Discrete Structural Systems duration), impact and impulsive loading is examined in detail. Discrete structural systems which under the same loading applied statically exhibit snap-through buckling are mainly considered. Emphasis is focused on the coupling effect of .
