Employing the method of least squares and quadratic B-spline polynomials, different statistical models were tested to identify the most appropriate to model the mean trajectories of live weight and carcass yield of Nile tilapia (Oreochromis niloticus). Data of live weight (8,758) and carcass yield (2,042) of tilapias with ages between 106 and 245 days were obtained from 72 families derived from 36 males and 72 females. The sex and tank variables were considered as classificatory and the coefficients of quadratic polynomials B-spline of two to five intervals of the same size were used as covariables. According to most fit criteria used, the models with quadratic B-spline polynomial with five intervals of the same size presented the best adjustments. The increase in number of intervals of B-spline polynomial improved the fit of the polynomials to the data. The inclusion of classificatory effects from sex, tank, the interaction of these effects and the quadratic polynomial B-spline nested in this interaction indicated that, over time, each sex, grown in different tank, presented different mean trajectory, necessitating the inclusion of nesting time in the interaction sex x tank in order to avoid the under or overestimation of breeding values of the selection candidates in breeding programs of this species.

With the advance of mathematical methods throughout the centuries, in particular with respect to the differential calculus, the notion of fractional derivative emerged with Leibniz and later developed by several well known scientists. Today that formalism is well used in the study of diffusion phenomena among other areas. We extend the fractional indices to matricial indices and develop a formalism to handle this generalized derivative, as well as other operators, functions and functionals in mathematical physics, originally defined for natural indices. Here we only consider 2x2 hermitian and anti-hermitian matrices. These matrices are associated to the well known Pauli matrices and Hamilton's quaternions. Applications with mathematical physics functions are presented

The aim of this study was to evaluate the knowledge of Hygienists (TSB) and Dental Auxiliaries (ASB) in relation to their roles regulated by Law number 11.889, December 24th, 2008, and formation of them and capacitating received before they had been admitted in public health system. It’s a transversal and descriptive study where the target population were TSB and ASB (N=76) that works in public service from 5 cities of the DRS II-SP. Data collection was performed by semi-structured instrument with opened and closed questions. The answer rate was 90.79% (n=69). The results showed that the majority of professional know part of their duties (56%) Near half of them had formation course (47.8%). In relation to information received during formation courses, 80% stated had received all information necessary to actualization of knowledge, however, 84% stated to feel necessity to actualize their knowledge to develop their works, 58% of professionals said that they don’t receive capacitating after they had been admitted. It was possible to conclude that the majority of professionals know part of their roles, has formation course and the majority don’t receive capacitating when they are admitted in public health system, however, it was observed that a part of them don’t have specific formation yet and don’t know part of their roles according to current legislation
