Mathematical Considerations Regarding the Stability of Trace Elements Systems by Polynomial Regressions

In this paper we generalise the mathematical model which describes the stability conditions of the human body considered as a big cybernetic system that lives in the normal condition by feed-back. Starting by a linear approximation, we generalise the stability's conditions in the polynomial case of dependencies between trace elements determined in organs of the human body. We tested this model on traces of: Fe, Zn and Co. These elements were determined in breast tissues samples which have different diseases.
