Quantum corrections to gravity and their implications for cosmology and astrophysics
The quantum contributions to the gravitational action are relatively easy to
calculate in the higher derivative sector of the theory. However, the
applications to the post-inflationary cosmology and astrophysics require the
corrections to the Einstein-Hilbert action and to the cosmological constant,
and those we can not derive yet in a consistent and safe way. At the same time,
if we assume that these quantum terms are covariant and that they have relevant
magnitude, their functional form can be defined up to a single free parameter,
which can be defined on the phenomenological basis. It turns out that the
quantum correction may lead, in principle, to surprisingly strong and
interesting effects in astrophysics and cosmology.Comment: 15 pages, LaTeX, WS style, contribution to the Proceedings of the

Rural establishments environmental management and insertion in production chains of oleaginous crops for biofuels.
Building upon a set of socio-environmental impact assessments carried out in five rural territories across the country, regarding the context of increasing demand for oleaginous crops for biofuels production, this study presents the sustainability assessment of rural establishments in those territories, aiming at checking the impact results against current local agricultural settings. The main results point out that, in general, the ecological dimensions of sustainability, such as Landscape Ecology and Atmosphere, Water, and Soil quality indicators, show adequate field conditions, seemingly not yet negatively affected by inputs and natural resources pressure increases, predicted as important potential impacts. On the other hand, most valuable positive consequences expected from the socio-environmental impact assessments, such as improved Socio-cultural Values and Management & Administration indicators, are still opportunities to be realized, if sustainable local rural development is to occur under the emerging agro-energy scenario
