Abstract

The goal of this study is to model the changes induced by thermal neutron irradiation in some fatty acids with important biological role. These changes could be experimentaly evidenced by the nonlinear optical answer of the samples under non-destructive laser light, while in the liquid crystal state, a state involved in many mechanisms from the living matter. The experimental data were processed with Table Curve3D computer program that gives the possibility to forecast the behavior of other samples and to model it with different equations. For simulating the dynamics of the phenomena inside the material, a model based on Runge-Kutta functions in MATLAB was used. This method is adequate for modeling the interaction of different external signals with different materials, by using appropriate parameters and time intervals..
