Transport processes in biological systems: Tumoral cells and human brain

The entropy generation approach has been developed for the analysis of complex systems, with particular regards to biological systems, in order to evaluate their stationary states. The entropy generation is related to the transport processes related to exergy flows. Moreover, cancer can be described as an open complex dynamic and self-organizing system. Consequently, it is used as an example useful to evaluate the different thermochemical quantities of the transport processes in normal and in tumoral cells systems. (C) 2013 Elsevier B.V.
