Da escassez ao estresse do planeta: um século de mudanças no ciclo do nitrogênio

Heavy metals and pesticides are usually associated with the main problems humankind has created in the natural environment. However, compounds with characteristics of essential macronutrients are causing serious environmental changes that could intensify, compromising the diversity of life on the planet. This is the case of nitrogen compounds, produced by industrial processes for use in intensive agriculture in addition to those unwittingly produced from human activities, available in excess in the environment. These compounds warrant greater attention from researchers in various fields of knowledge and public agencies for environmental control, toward minimizing their availability in the environment, thereby returning conditions closer to the natural environmental balance of the planet.

Origin of the peculiar eccentricity distribution of the inner cold Kuiper belt

Dawson and Murray-Clay (Dawson and Murray-Clay [2012]. Astrophys. J., 750, 43) pointed out that the inner part of the cold population in the Kuiper belt (that with semi major axis a < 43.5 AU) has orbital eccentricities significantly smaller than the limit imposed by stability constraints. Here, we confirm their result by looking at the orbital distribution and stability properties in proper element space. We show that the observed distribution could have been produced by the slow sweeping of the 4/7 mean motion resonance with Neptune that accompanied the end of Neptune's migration process. The orbital distribution of the hot Kuiper belt is not significantly affected in this process, for the reasons discussed in the main text. Therefore, the peculiar eccentricity distribution of the inner cold population cannot be unequivocally interpreted as evidence that the cold population formed in situ and was only moderately excited in eccentricity; it can simply be the signature of Neptune's radial motion, starting from a moderately eccentric orbit. We discuss how this agrees with a scenario of giant planet evolution following a dynamical instability and, possibly, with the radial transport of the cold population. (C) 2014 Elsevier Inc.

A study of low velocities regions near the Roche lobe during the gas giant planets formation

In this paper were studied regions close to the Roche lobe of a planet like Jupiter, in order to find regions with low velocities. We simulated a two dimensional and non-self-gravitating disk, where tidal and viscous torques are considered, using the hydrodynamic numerical integrator FARGO 2D. As stated earlier we are interested in find low velocities regions for in future works study the possibility of satellites formation in these regions.

Ciências da Funcionalidade Humana e Sustentabilidade Ambiental: a junção das partes constitui o todo?

The content of this article addresses two complex issues that concern contemporary society: Science of Human Functioning and Environmental Sustainability. On the one hand, the Science of Human Functioning, meeting the principles of the International Classification of Functioning (ICF) and Universal Design, aim the development of accessible projects, products and environments, used by everyone, at the greatest extent possible, free from adaptation or plans to remove architectural barriers. The Universal Design is a process for creating products that are accessible to everyone, regardless their personal characteristics, age, skills and needs. On the other hand, Environmental Sustainability, with principles already imbricated in the Science of Human Functioning, traverses towards the acquisition of realistic measures for the segments of human activities. Based on the emphasis of the sustainable development, it aims to meet current needs not compromising the possibility of future generations to meet their own needs. Thus, it seeks the balance in coexistence between men and the environment by taking care of environmental, social and economic aspects and seeking for alternatives to support life on Earth with no harm to the quality of the planet in the future. It is argued that the combination of the issues contains relevant potential for interdisciplinary action, bringing together professionals from several fields of knowledge that, by socializing their experiences aiming at improving the human functioning and quality of life of people and environment, will be able to innovate and reinvent the knowledge for benefiting welfare, thus contributing effectively to society.

Apontamentos críticos para o tratamento da questão ambiental na perspectiva da emancipação

The belief in the existence of an ecological crisis that would affect the future of the planet, is one of the factors that causes the appearance of ecological concern, resulting in the adoption of non-predatory consumer practices and more respectful relationships with non-humans beings. This study starts from the assumption of the existence of an environmental question, and aims to investigate some of the cultural causes of human predation and identify possible ways in which environmental question can be treated critically to search overcomes. Follows the reasoning that western society as a complex of social relations, the capitalism, as a mode of production utilities and rational right, are all consequences of the modern rationality, cognitive and moral logic that transforms people and nature in satisfaction instruments of individual interests. However, despite being identified as the causative root of environmental question, modern rationality takes with it enough to promote the development of ecological respect, necessary in confronting and overcoming the environmental question, as it will be applied as a principle in redefinition of the relationship of human beings with themselves and with nature. And modern rationality can also make capitalism more efficient in the use and reuse of materials so as to consume fewer resources on the planet to satisfy human needs.
