1. Catholic Education in France in the Interwar Period: Religious Life, Religious Orders, Adaptations. Research perspectives
Abstract The history of French teaching congregations during the twentieth century is quite unknown. Nevertheless, their experiences are of very high interest for historians who want to focus on social and religious transformations in contemporary societies. This research outlines two important events through some congregational archives: first, from World W

2. Osciladores harmÃnicos acoplados dependentes do tempo. / Harmonic oscillators coupled time-dependent.
Neste trabalho apresentamos soluÃÃes clÃssicas e quÃnticas de osciladores harmÃnicos acoplados dependentes do tempo. Nesses sistemas as massas, frequÃncias e o parÃmetro de acoplamento sÃo funÃÃes do tempo. Quatro sistemas sÃo investigados. Para obter as soluÃÃes clÃssicas usamos uma transformaÃÃo de coordenada e momento juntamente com uma tr

3. 15:1 Resonance effects on the orbital motion of artificial satellites
Abstract The motion of an artificial satellite is studied considering geopotential perturbations and resonances between the frequencies of the mean orbital motion and the Earth rotational motion. The behavior of the satellite motion is analyzed in the neighborhood of the resonances 15:1. A suitable sequence of canonical transformations reduces the system of

4. Economia desregrada : Marx, Keynes e Polanyi e a riqueza no capitalismo contemporaneo
In an effort to pick the substratum of the contemporary capitalism, this thesis intends to identify the ways how the disappearance of the rules and of the borders leaves the capital given to their own movement laws. In that sense, it proposes that an approximate picture of the contemporary capitalism can be drawn through the concept of de-ruled economy (Intr

5. Mapeamentos Simpléticos em Dinâmica Asteroidal / Symplectic mappings in asteroidal dynamics
In this work, we developed a symplectic mapping which allow us to study the dynamical behaviour of asteroidal resonances in the frame of the non-planar elliptic restricted three-body problem. To obtain such a mapping we combine a symplectic scheme similar to that of Hadjidemetriou (1986) together with an asymmetric expansion of the disturbing funtion (Ferraz

6. Use of features derives from class proportions in a pixel for the multispectral classification of remote sensing images / Utilização de atributos derivados de proporções de classes dentro de um elemento de resolução de imagem ("pixel")na classificação multiespectral de imagens de sensoriamento remoto
The spectral energy collected by the Remote Sensing instrumentation is the integration, called mixture, of the energy reflected or emmited by the objects, called primary components of the mixture, contained in a picture element. The land use classes in a scene can be described in terms of these components proportions, specially for forest targets. The object

7. Canonical formulation of linkage thermodynamics.
The canonical structure of the group of thermodynamic potentials obtained from the energy of a physico-chemical system removes any possible distinction between physical and chemical binding phenomena. Transformations of these potentials by means of Jacobians give linkage relations for equilibrium thermodynamics. Linkage matrices are introduced to explore the

8. Dynamics of Systems with Large Number of Degrees of Freedom and Generalized Transformation Theory*
A generalized transformation theory which leads to a non-Hamiltonian description of dynamics is introduced. The transformation is such that all averages of observables remain invariant. However, the time evolution of the density matrix can no longer be expressed in terms of a commutator with the Hamiltonian. Therefore such transformations are not canonical i

9. Explanation of parity nonconservation
Space inversion and other discrete symmetries are treated within the frame of a theory of fundamental forces based only on general considerations of causality, symmetry, and stability, without ad hoc differential equations. The basic space-time ˜M is the Einstein universe R1 × S3 as a causal (or conformal) rather than a pseudo-Riemannian manifold. Its conn
