Повний текст джерелаThe objective of this Ph.D. project is to investigate the electrochemistry of the pure phases, components of the Zn-Al-Mg coating alloys. The electrochemical data was used as an input for the prediction of corrosion behavior of the multi-phase alloy coatings. To this end, a database of elemental polarization curves was established as a function of pH by using atomic emission spectroelectrochemistry (AESEC). Dealloying of the MgZn2 intermetallic and α-phase of Al-Zn (Zn-68Al) were investigated at pH=10.1 represent the extremes of Mg and Al content in the Zn-Al-Mg alloy coating, respectively. In the cathodic polarization, the Zn(0) enriched layer was formed in both cases by selective dissolution of Mg and Al, respectively. However, the influence of this layer on cathodic dealloying differed: for MgZn2, Mg selective dissolution was restrained by the dealloyed layer, whereas for Zn-68Al, Al selective dissolution was not affected by this layer. It was observed that the onset of active Zn dissolution coincided with a reduction in the Al dissolution rate, suggesting an inhibitive effect of Zn dissolution on Al dissolution. It was observed that Al dissolution in alkaline media was limited by the dissolution rate of the Al(OH)3 film, evidenced by potential independent Al dissolution. The most stable corrosion products formed by electrochemical measurements, precipitated species in the solution during titration experiment and the thermodynamic simulation were reasonably coherent with each other. Most of the precipitated species formed in the solution corresponded reasonably well to those predicted by thermodynamic database. It was in a good agreement with the corrosion products of the alloy, characterized after the electrochemical measurements. Therefore, it can be concluded that the thermodynamic database can be used to predict and eventually model the real corrosion situation

Esta pesquisa consiste fundamentalmente no estudo crítico de uma seleção de poemas de Henriqueta Lisboa, em especial da obra Flor da morte (1949), naquilo que ela tem de “poesia pura”, segundo concepções estabelecidas a partir das pesquisas de autores que se pronunciam sobre o tema, como Henri Brémond, Henry Decker, Paul Valéry e Robert Penn Warren, e considerando as concepções de poesia expressas pela própria poeta em seus textos ensaísticos. Consideramos, também, textos de estudiosos da obra de Henriqueta Lisboa e da “poesia pura”, como forma de enriquecer nosso estudo, buscando refletir e tentar responder a alguns questionamentos: como a “poesia pura” comparece na obra de Henriqueta Lisboa? A partir dessa inquisição surgem, por conseguinte, outras indagações: em que quantidade, em quais poemas da obra Flor da Morte, segundo qual conceito de poesia pura, em que possível diversidade de manifestações? O fundamento teórico da pesquisa provém de teóricos como de Giorgio Agamben, Jacques Derrida, Emanuel Levinas, Maurice Blanchot, principalmente, Martin Heidegger, entre outros. Por fim, relacionamos os textos estudados para o estabelecimento das conclusões, acrescidas das possibilidades de descobertas geradas por essas leituras, além de levantarmos questões relativas à arte, à literatura brasileira, à escritura, especialmente, e a crítica literária contemporânea, de forma enriquecida e sistematizada, tudo sob o viés da literatura contemporânea.

Análise do processo variável da emergência étnica no entorno do Parque Estadual da Serra do Brigadeiro na Zona da Mata de Minas Gerais. A Cultura Puri foi silenciada durante os últimos duzentos anos, a partir da Educação Popular, seu processo intercultural possibilitou a recriação de identidades. Através de entrevistas, de rodas de narração de histórias e das notas de campo em comunidades rurais recupera fontes orais. Capta um encadeamento discursivo recorrente entre violência, fabulações naturalísticas e vontade de liberdade. Se inscreve na tradição da crítica cultural como motor da transformação social. Associa-se à saga colonial migratória, e recoloca a temática dos movimentos sociais. Critica o monoculturalismo do saber através da inteligibilidade dos movimentos sociais e da ecologia de saberes. Enfatiza a constituição de uma outra temporalidade e da dilatação do tempo presente, o que aprofunda as análises de longa duração. Aborda conceitos que se interrelacionam complexamente, tais como: estrutura de sentimentos, hegemonia, residual e emergencial. Toma como referências os estudos de Raymond Williams e de Boaventura de Sousa Santos.

Повний текст джерелаThe hydrolysis of magnesium alloys wastes in seawater (i.e. 3.5 wt.% of NaCl aqueous solution) is a new approach which allows both in-situ hydrogen production and the valorization of a priori non-recyclable wastes. The objective of this research work is to optimize the reactivity of magnesium-based wastes by ball milling with additives. Therefore, we investigated the effects of the main milling parameters (e.g. milling atmosphere, milling rotation speed, order of the addition of additives) on the reactivity of WE43 alloys and Mg – Al alloys wastes. A « scale-up » of the materials treatment process was conducted to explore the possibility of industrializing the process. In addition, we have shown that milling under argon is more advantageous than under hydrogen.Mg – Al alloys (more precisely AZ91) are the most widely used. In these alloys, Al forms with Mg the intermetallic Mg17Al12. To better understand the mechanism of hydrogen production from these binary Mg – Al alloys (Mg + Mg17Al12), evaluating the behavior of each of their constituents and their interactions is essential. In this regard, the chemical (i.e. hydrolysis) and electrochemical (i.e. corrosion) aspects of the reaction of Mg17Al12 with the model seawater solution and the effect of milling in the presence of additives (e.g. graphite, NaCl, MgCl2 and AlCl3) were studied. The evolution of the surface chemistry during polarization tests has proven experimentally (by Raman spectroscopy), for the first time, the formation of reaction intermediate and has allowed us to propose a mechanism of H2 formation.The interaction between Mg and Mg17Al12 was explored by comparing the properties of model materials of « AZ91 » (Mg + Mg17Al12). Using scanning electrochemical microscopy, the effect of galvanic coupling was studied at the interface of the two components of the material. In view of these studies, the contribution of Mg17Al12 in the corrosion of AZ91 alloys was clarified. The intermetallic is corrosion resistant and accelerates the corrosion of Mg due to galvanic coupling. The various milling strategies adopted in this work were compared by applying them to a commercial AZ91 alloy. Mechanical treated materials with graphite and AlCl3 showed the highest hydrolysis performances.Finally, we semi-quantitatively evaluated the purity of H2 (the composition of the gas mixture and its humidity) produced. The impact of few experimental conditions (e.g. composition of the solution, temperature, ratio of the mass of powder to the volume of solution) is reported. Thus, it has been shown that an Mg hydrolysis reactor operating at room temperature with seawater produces « clean » hydrogen in-situ and can be considered as a « green » hydrogen on demand generator

Após séculos de opressão e de lutas, muitos dos grupos indígenas brasileiros sobreviveram apenas nas narrativas da história. Contudo, em alguns casos, eles deixaram fragmentos de cultura entrelaçados aos modo de vida urbana na atualidade. Na Zona da Mata mineira, região das últimas fronteiras liberadas para ocupação territorial a partir do último quarto do século XVIII e início do século XIX, encontrou-se registros paroquiais de batismos com evidências de resistência de um desses povos de floresta, o povo indígena Puri. Estes índios habitaram também no território da atual cidade de Miraí, antiga Freguesia de Santo Antônio do Muriahé, e parte de suas tradições estão mantidas, ainda que de forma esmaecida, como fragmentos de cultura ancestral presentes nas famílias que se auto-declaram como descendentes deste povo de floresta. Investigá-las no entanto, é um exercício da memória.
After centuries of oppression and fights, many aborigine Brazilians groups survived just in the narratives of history. However, in some cases, they culture. They left fragments of the culture interlaced the urban way of life in the present. The Forest Zone of Minas Gerais, of the last frontiers released for territorial occupation form the last quarter of the eighteenth century and early nineteenth century. We found registration of documents of Parish church of baptism with evidence of resistance to one of these people of the forest, the Puri aborigine. These aborigines also lived in the territory at the present Miraí, older Parish of Santo Antonio do Muriahé, and part of their traditions are maintained. Still dimmed form, an ancestral culture fragments investigate them. However, it is an exercise of memory.
