Experimental bifurcation diagrams for the heterogeneous catalytic oxidation of ethanol on a supported palladium catalyst are presented, depending on the oxygen or the ethanol content in the feed as control parameters. The identification of the bifurc

The entropy statement formulated by KLIMONTOVICH is discussed by investigating two examples: 1. Selfoscillations of nonlinear oscillators, 2. Laminar and turbulent flows in tubes. The precise meaning of this statement is clarified. It is shown that u

The entropy lowering is calculated in the laminar as well as in the turbulent regime. For the Poiseuille flow it is shown that the entropy lowering increases monotonically if while increasing the Reynolds number the energy of the flow is kept fixed.

The behaviour of the entropy is studied during a nonequilibrium phase transition. It is shown that for the generation of sustained oscillations the entropy decreases monotonously if the average oscillator energy remains fixed. This result is valid bo

The influence of external fluctuations on the bifurcational behavior of two-dimensional dynamical systems exhibiting limit cycles is investigated. Studying both exactly and approximately solvable examples it is shown that the variances of the externa

The concepts of entropy and lowering of entropy in comparison to the equilibrium state are introduced. It is shown that entropy lowering is connected with the contraction of the occupied part of the phase space due to the formation of attractors. As

We investigate the effect of additive colored noise on Hopf-bifurcating systems in the limit of small correlation times. It is shown that it results in an advancement of the oscillating regime. Several examples are studied.

Thermodynamics is a rather old discipline of physics, however, it is not oldfashioned. On the contrary,such modern topics as the hot big bang model, the theory of black holes, as well as the theory of biological systems /1,2/, show that thermodynamic
