The purpose of this work was the study of numerical methods for differential equations of fractional order and ordinary. These methods were applied to the problem of calculating the distribution of the concentration of a given substance over time in a given physical system. The two compartment model was used for representation of this system. Comparison between numerical solutions obtained were performed and, in particular, also compared with the analytical solution of this problem. Finally, estimates for the error between the solutions were calculated

An analysis of “Pretérito Perfeito Simples” (Simple Past Tense) and “Pretérito Per‐ feito Composto” (Compound Past Tense) in Brazilian Portuguese showed that such tenses must be distinguished according to semantic and pragmatic features other than temporal; both tenses can be used to express a situation that begins in the past and extends up to the present.
