✦ Synopsis

It is found that a periodic change of the surface tension is generated at the gas-liquid interface of an aqueous Belousov-Zhabotinsky (BZ) medium. It has been confirmed that the difference of the surface tension of the iron-catalyst between [Fe(phen),]j+ and [ Fe(phen)r]'+ is thedrivingforceofthisrhythmic phenomenon. Therhythmicchange ofthe surface tension is discussed in relation to the known effect of convective flow accompanied by the propagation of a chemical wave in the BZ reaction.

Interaction among various oscillating inputs may result in significant modifications in the behavior of a system under forced periodic control. Forced oscillations in the input flow rate and input concentrations of an exothermic continuous stirred tank reactor enable the stabilized operation of the

An infinite string, supported by the equidistantly spaced identical suspensions, is considered. Each suspension consists of a spring and a dashpot with viscous damping, in parallel. The small transverse oscillations of the string are affected by the viscous drag of an external medium. The concentrat
