✦ Synopsis

The applicability of the soft and hard impact models in modeling of vibro-impact systems is discussed in the paper. We derive the conditions which allow the same rate of energy dissipation in dynamical systems which use both impact models. The advantages and disadvantages of both models in modeling are discussed. We show that in the case of the stiff base both methods give the same results but the elastic base application of the hard impact model leads to wrong results.

The Zn 2Ψ‰ -glutathione system is studied as a model for metal-peptide systems where some critical factors must be considered when using voltammetric techniques for the determination of stability constants. These factors are the presence of side reactions (in this case, both the protonation of glutat

## Abstract The motivation for this study is the need for accurate numerical models of melt flow instabilities during Czochralski growth of oxides. Such instabilities can lead to undesirable spiralling shapes of the bulk crystals produced by the growing process. The oxide melts are characterized by
