The back cover picture shows schematics of a pyrotechnic detonator together with a simplified model of a time delay element illustrating the heat flows that affect its performance. The background depicts a sequential blasting event in an open pit quarry. Details are discussed in the article by Walter W. Focke et al. on page 55 ff.
