On the long standing issue of an R phi(2) coupling between gravity and a massless free scalar field

Using 2-body trees on a flat space background, it is shown that the actions A[g, φ] = (Latin small letter esh) d4x√-g [(R/2K) + (1/2)(gμν ∂μφ∂νφ + λRφ2)] and Ā[ḡ, φ̄] = (Latin small letter esh) d4x√ - ḡ [(R̄/2k) + (1/2) ḡμν∂μφ̄∂ νφ] describe the same theory at the tree-level in this case. We also demonstrate the quantum equivalence (at one-loop) of the barred and unbarred systems for λ == -1/6 (conformal coupling).

A nova habitação social: concepções inovadoras aplicadas em ZEIS

Discussions on the production of housing for residents of low income, in Brazil, has come a long, but still no great solutions. Not only a political problem, the issue of housing involves also social and economic issues. From the beginning there was a downward grade of the slum villages more sophisticated more precarious, as if the social scale. And that is what this work will be done. In an attempt to produce forms of housing for low-income population, but not to be a mere product of capitalism, or political propaganda, but to try to reach a real solution to the problem. The project will propose new forms of construction, use of renewable energy, reuse of water and other, besides new forms of construction, the project aims to create a sustainable education to future residents

The Challenges of Psychology at Work in Mental Health: the drugs issue.

This article aims to show that the challenges of psychology in working with mental health in the field of drugs is traversed by both the conceptions molded by biopolitical forces (FOUCAULT) as the decadence of modern democracy (AGAMBEN), and visible features in the current treatment given in Brazil to issue of smoking (SILVA), as well as urbanistic projects such as the case of Luz district in São Paulo (LEITE & CASTRO). In this sense, it leads us to question about what is prohibited, about who actually suffers the punishment, in short, about what do we really take care when we take into account the Unheimlich (FREUD) and other social interdicts (BATAILLE).
