ABSTRACT In "Kritik der praktischen Vernunft", the concepts of factum of reason and of feeling of respect for the moral law generate great interpretative divergences. This paper aims to present the interpretations of Zeljko Loparic, Guido Antônio de Almeida and Flávia Carvalho Chagas.

The objective of this paper is to study the vortex shedding from a circular cylinder near a moving ground; this is done using the Vortex Method. A moving ground has been widely used in the field of experimental vehicle aerodynamics, especially of high-performance racing cars, to properly consider the ground effect on the vehicles aerodynamic. In experimental work as well as in numerical simulations, the ground plane develops a boundary layer that interferes with the body viscous wake, leading to not so precise results. A ground moving with the incoming flow velocity, however, does not allow the development of a boundary layer. The results of our numerical simulations show that the critical drag behavior is directly related to a global change in the wake structure of the cylinder in the ground effect. Comparisons with experimental data are encouraging.

This paper concerns the numerical simulation of the flow around an oscillating circular cylinder, which moves with constant velocity in a quiescent Newtonian fluid with constant properties. For each time step of the simulation a number of discrete Lamb vortices is placed close to the body surface; the intensity of each of these is determined such as to satisfy the no-slip boundary condition. The aerodynamic loads acting on the surface of cylinder are computed using the integral formulation derived from the pressure Poisson equation. The influence of the frequency and amplitude oscillation on the aerodynamic loads and on the Strouhal number is presented and discussed.

ABSTRACT Critical remarks have been made aboud the use of immovable lines fixas of traps method. In this paper, modifications are suggested for this technics, which where tested in the cerrado of the Parque Nacional de Brasília, DF

In this work are determined the productive periods and the number of fixed embryos/pregnancy in the species of non-flying small mammals in four different stages of regeneration of the Atlantic Forest in Silva Jardim and Casimiro de Abreu (Rio de Janeiro). Akodon cursor, Neclomys squamipes and Oryzomys nigripes showed repeated oestrus in all seasons. To A. cursor the average number in ten parturitions was of 3.6 youngs; in six parturitions N. squamipes and O. nigripes it was of 3.5 and 4.0 youngs, respectively. In these three species, the embryos fixed rather in the right horn of the uterus.
