1. AN ALTERNATIVE MODEL FOR CONCURRENT PROGRAMMING IN LUA / UM MODELO ALTERNATIVO PARA PROGRAMAÇÃO CONCORRENTE EM LUA
The popularization of multi-core processors and of technologies such as hyper-threading indicates a different approach to the evolution of processors. This new approach brings about an increased interest in concurrent programming and the exploration of parallelism in order to achieve better performance. However, concurrent programming models now in use are s

2. Removing the Wess Zumino fields in the BFFT formalism
In this paper we give a method that removes the Wess Zumino fields of the BFFT formalism. Consequently, we derive a gauge invariant system written only in terms of the original second class phase space variables where important physical properties can be raised. Here, the Wess Zumino fields are considered only as auxiliary variables that permit us to reveal

3. On the static properties of baryons in the Skyrme model
We use a modified version of the Skyrme model in which the stabilizing fourth-order term is separated in two parts with different parameters that are introduced in the Lagrangian and could vary independently. The predictions for the static properties of baryons are calculated and results are compared with the respective experimental values and those of other

4. Pion mass dependence of nucleon magnetic moments
The relevance of the pion mass, provenient from a term which explicitely breaks chiral symmetry in the Lagrangian, for nucleon magnetic moment in the frame work of the Skyrme model in two different versions: the usual one model and a modified one which includes a coupling to a light scalar meson field, the sigma s( Brazilian Journal of Physics.

5. Fenomenologia hadrônica no modelo de Skyrme / Hadronic phenomenology in Skyrme model
Neste trabalho estudamos aspecto estruturais de modelos onde os bárions são tratados como sólitons quirais, tais como o proposto pó Skyrme e variantes, contendo um termo estabilizador de sexta ordem, proporcional à corrente bariônica. Modelos deste tipo têm sido bastante estudados na literatura e suas predições para as propriedades estásticas do n�
