The P1 and P2 constants can be, also, experimentally determined, using the following procedure: an experiment as it was presented in the first part of the Paragraph is made; after the adsorption time is reached, the experiment is stopped; the zeolite is extracted from the adsorption column and sectioning with transversal cuts the material in different points associated to the 0p axis, the distance on the 0p axis between the last section which have reached at the saturation regime and the section associated to the output edge of the zeolite is determined, resulting the value ps = 4cm.

According to Ulrich the general theory of systems is a field of science where the structure, interconnections and behavior of any system is in focus [10].
It interacts by the exchange of material, energy or information [26].
On the technological level, for example, new production and product technologies, as well as new materials and innovations in the IT sector can be considered as a catalyst [33].

Introduction High hardness and high strength cutting materials, such as hardened steel, have become an important research topic in industry and academia.
One type of cutting tool suitable for difficult materials is ceramic cutting tool.

Material nonlinearity was considered through a concentrated plasticity approach considering strength and stiffness deterioration effects [9, 10].
This demonstrates that using the IFBD procedure to define the behaviour factor not only ensures material savings but also an overall better seismic performance.
