Bücher von Marcos Nobre

In this timely book, Brazilian political philosopher Marcos Nobre analyzes the social and political roots of the election of Jair Bolsonaro to the presidency of Brazil and shows how this process is connected to the rise of new far-right movements threatening democracy around the world. Nobre describes the rise of the movement that elected Bolsonaro as a reactionary and anti-democratic highjack of the democratic impulse unleashed by the June 2013 uprisings, when millions of Brazilians took to the streets to protest against a dysfunctional political system, and frames the Brazilian case within the global crisis that exposed the limits of a democracy based on the neoliberal consensus after the 2008 financial crisis. According to Nobre, the June 2013 uprisings in Brazil was part of the global cycle of popular protests that swept many countries between 2011 and 2013, reclaiming a new model of democracy which could go beyond bureaucratic and technocratic parties and cabinets. However, in Brazil, as in many other places, this initial democratic impulse was captured by new far-right movements which are now posing serious threats to democracy.  This book intends to collaborate in a change of attitude, both theoretical and practical, that may help finding ways of fighting the authoritarian threat to democracy as well as of deepening democracy as a life form. The decline of neoliberalism not only did not produce any effectively progressive realist alternative, but also opened the way for a dispute over models of society in which democracy itself has ceased to represent the primary reference in disputes over the best way to regulate life in society. Democracy is no longer self-evident, it is in danger. And the only way to save it is by inventing new democratic practices to overcome the limits imposed by institutional political systems no longer capable of channeling the real struggles in the societies they claim to represent.

Neste trabalho foram investigadas a síntese, caracterização estrutural e espectroscópica e a análise do potencial catalítico de catalisadores do tipo perovskita SrTiO3 e das perovskitas duplas de Sr1-xKxTiCux/2O3, onde x = 0,2 , 0,3 e 0,5, na preparação do biodiesel via rota etílica. A partir da estrutura hospedeira do titanato de estrôncio SrTiO3 foram investigadas as soluções sólidas contendo átomos de cobre e potássio com as seguintes estequiometrias: Sr0,8K0,2TiCu0,1O3, Sr0,7K0,3TiCu0,15O3 e Sr0,5K0,5TiCu0,25O3, preparadas por síntese química pelo método Poliol Modificado.O estudo catalítico foi realizado a partir da catálise heterogênea, com a adição das nanopartículas em solução contendo óleo vegetal e álcool etílico. O processo de transesterificação foi realizado em um reator de escala laboratorial, desenvolvido junto ao LaCCeF, com sistema de agitação e temperatura controlada. Neste processo, os principais produtos formados foram o biodiesel e o glicerol residual. Ao longo da execução dos experimentos foram controlados os parâmetros do processo, como o tempo da reação, concentração do catalisador, tempera¬tura e o grau de agitação. Ao final da reação foi possível filtrar o
