Desenvolvimento de um torquímetro de precisão para o estudo do desempenho de implantes osseointegrados

This paper has as objective, to present the project, the construction and the results obtained in the study of the osseointegration with a torque gauge of high precision. The torque gage, especially developed for this research type, was used to improvement of odontological research on osseointegration of dental implant. The implants were done in seven rabbits that were available after 21 and 42 days. In some rabbits were made ultra-sonic stimulations at rabbits’ implants. The results showed that the torque to remove the implant of the rabbits is directly proportional at the time of osseointegration and that the ultra-sonic stimulations can also influence the torque in some cases.

Global justice and environmental governance: an analysis of the Paris Agreement

Based on the major normative political theory contributions on global climate justice, the present paper analyzes the new international agreement on climate change, adopted at COP 21 in Paris (2015). Therefore, a literary review of the extensive normative theoretical discussion about global climate justice is made, with special attention to the two approaches that have permeated multilateral political negotiations - historical responsibility and equal per capita emissions. From this normative discussion, this paper recalls the global climate change negotiation process, focusing on the Kyoto Protocol. Next, the analysis emphasizes on the Paris Agreement in an effort to evaluate the normative questions on justice and equity within the environmental governance regime. Finally, the set of conclusions indicates that, although the flexibility of the Agreement has encompassed some dimensions of responsibility, necessity and ability to bear the costs, the most complex dimensions of justice and equity has not been completely solved, which may hinder the operation of environmental governance in a near future.
