Monetary and fiscal institutions have played a decisive role in the stabilisation of the Brazilian economy since the mid-1990s. In Brazil institutional reforms were predominantly made in response to a succession of internal ...

A comparison of the composition and structure of parasite communities of the Brazilian flathead, Percophis brasiliensis Quoy et Gaimard (Perciformes: Percophidae) among seasons during one year was carried out in the Argentine ...

This paper presents the comparison between the numerical and analytical results of a spacecraft attitude propagation for a spin-stabilized satellite. Some external torques are introduced in the equations of the motion and ...

In this paper, analytical attitude propagators for spin-stabilized satellites are analyzed. For this purpose, external torques are introduced in the motion equations such as solar radiation pressure torque, aerodynamic ...

This paper presents a study of a modeling scheme for the spin stabilized satellites attitude, entirely developed in terms of quaternion parametrization. The analysis includes numerical propagation of the rotational motion ...

A large historiographic tradition has studied the Brazilian state, yet we know relatively little about its internal dynamics and particularities. The role of informal, personal, and unintentional ties has remained underexplored ...

Considering that Brazil has committed to the Financial Stability Board (FSB) to adopt bail-in in order to increase the financial sector stability and to enable a fast and orderly reaction to financial crisis through the ...
