A simple solution for the flavor question

We consider a simple way of solving the flavor question by embedding the three-family standard model in a semisimple gauge group extending minimally the weak isospin factor. Quantum chiral anomalies between families of fermions cancel with a matching of the number of families and the number of color degrees of freedom. Our demonstration shows how the theory leads to determination of families structure when the standard model is the input at low energies. The new physics is limited to start below a few TeVs within the reach of the next generation colliders.

Actual Brazilian habitations in wood: A technology in development or a question of fashion?

Over the past few years there have significantly been increased the articles that approach the constructions in wood or with structure in wood in the specialized Brazilian magazines. This increase brings up indications that the incorporated values to these habitations are modifying, however it is not so simple to conclude that these issues can be associated to the development of incorporated technologies to the constructive system. The work presents, firstly, a survey performed in these publications that had the objective to verify which the constructive systems in wood is being more executed, under which cultural and technician standards. From that survey it was performed a study of the habitations constructed in mixing system whose structures are timbers and walls in masonry. The aesthetic and cultural questions involved are argued considering mainly that these habitations belong to a social class whose purchasing power increased.

De platon à candido: la littérature en question

Cette étude propose, à partir de quelques conceptions de littérature qui circulent dans le domaine de la critique littéraire, une approche théorico-critique. Pour ce faire, on partira de la vision platonicienne et aristotélicienne, pour ensuite discuter les contradictions observables dans les concepts mêmes de littérature. A la fin, on se décidera pour une conception spécifique, en raison de sa flexibilité.
