Studies about structural integrity are very important when it desires to prevent disasters associated with flaws inherent in materials used in structural components. The welded joints in steel pipes used to conduction and distribution of oil and gas correspond to the regions most susceptible to flaw. Aiming to contribute to this research line, the present study was designed to assess experimentally the structural integrity of welded joints in steel pipes API 5L X70 used in pipeline systems. This assessment is given from tests of CTOD, whose aim is simulate in laboratory the real behaviour of crack from of his propagation on the welded joint obtained by high frequency electric resistance welding. In this case, the analyses are performed from specimens SE(B) obtained directly of steel pipe API 5L X70. The proposed methodology involves tests of CTOD at lower temperature, in order to assess the toughness of material in critical operation conditions. From performance of CTOD tests, was possible assess the toughness of welded joints in terms of quantity through CTOD parameter and in terms of quality from behaviour of curve load versus CMOD. In this study, also, sought to compare CTOD’s results obtained through rules ASTM E1820 (2008) and BS 7448 (1991). Although the two standards cited previously have adopted different parameters to calculated the value of CTOD, concluded that the values of CTOD tend to converge for a common value

The study of mechanical properties of high-alloy special steels is of great interest of the steel industry due to the great demand by companies that manufacture automotive components of high criticality, and also because of its high commercial value. However, the development of this type of alloy metals demand highly technical knowledge. Among these extremely important kinds of steel, the subject which is the interest of this study is the special steel modified by niobium. The manganese and niobium are the main alloying elements in the composition of these steels, both of them increase the stability of the austenite region, however, manganese increases the hardenability and tensile yield strength, and niobium increases the mechanical strength and promotes refining the grain. The mechanical characterization of steel SAE 1312 modified the niobium was made in order to gain a better understanding of the influence on the mechanical properties caused by aging at different temperatures and for different reductions in the drawing of gauge material. This characterization was made by means of tensile test and hardness. This material showed an increase in yield strength and hardness when gauge with large reductions during the wiredrawing, but when subjected to aging temperatures higher than 300 ° C had a slight loss of these properties

Inserida na linha de pesquisa Política e Cultura, esta tese entende a Religião como um poder simbólico e como um fenômeno que penetrando a política e a cultura de um povo, de uma nação, estabelece valores, interfere na elaboração das normas jurídicas, estabelece e resignifica os costumes e as tradições. Através de vasta documentação afirmamos que a Igreja Católica no Brasil se manteve ligada ao Estado e interferiu na vida política e cultural do país até os anos de 1970. Neste período a Igreja manteve uma postura de combate ao socialismo e às esquerdas que se manteve posteriormente, porém, a Teologia da Libertação se desenvolveu tomando os conceitos marxistas e as Ciências Políticas como fundamento para suas análises. A ruptura das relações entre a Igreja e o Estado no Brasil nos anos de 1970 e o desenvolvimento da Teologia da Libertação são analisados a partir do pensamento de Antonio Gramsci, considerando a Igreja Sociedade Civil. O rompimento da hegemonia da Igreja Católica em relação ao Estado efetivou a organização das pastorais e movimentos de base em busca do estabelecimento de uma nova ordem política e assim o estabelecimento de uma nova hegemonia da Igreja no Brasil dos anos de 1990.

A presente pesquisa aborda a formação da identidade da religião católica no Brasil colonial e seus reflexos nos desregramentos recorrentes na segunda metade do século XVIII, na diocese de São Sebastião do Rio de Janeiro durante o episcopado de D. José Joaquim Justiniano Mascarenhas Castelo Branco (1773 1805) tendo sido este o primeiro bispo a assumir o comando de sua diocese natal. O tema proposto aborda diretamente a complexa relação entre os poderes temporal, representado pelo Estado português personificado na figura da realeza , e o espiritual, pertencente à Igreja sua representatividade máxima no local varia de acordo com a posição ocupada pelos clérigos, respeitando-se, assim, a hierarquia eclesiástica (monges, freiras, padres, bispos etc.). Apesar da obrigatoriedade do catolicismo na colônia, a coroa metropolitana não foi capaz de dar o suporte necessário para o estabelecimento de uma religiosidade fiel às determinações do Concilio de Trento, conforme determinava o direito de Padroado. Isso levou à formação de um catolicismo colonial por vezes aparente. A miscigenação étnico-cultural deu brecha para o surgimento de praticas sincréticas e diferentes comportamentos sociais reprovados pela Igreja. O desvio de conduta era um problema que afetava, não só os fiéis, mas também o clero, sendo este composto na época por sacerdotes mal formados e alguns estrangeiros de índoles duvidosas. Assim, os bispos do Brasil do século XVIII tiveram que lidar com problemas que eram, na verdade, reflexo da realidade da estrutura colonizadora local onde, apesar de ter sido a Igreja uma importante aliada do Estado lusitano, e vice-versa, havia também grande rivalidade entre ambos. Dessa forma, ocorriam na época constantes embates entre as autoridades civil e religiosa, as quaisuniam-se e desuniam-se de acordo com seus interesses.

The Nossa Senhora da Conceição Seminary, installed in 1894, by Dom Adauto Aurélio de Miranda Henriques, first Paraíba Bishop, and the Episcopal Seminary of the Sagrado Coração de Jesus, implanted in 1913, by Dom José Thomas Gomes da Silva, first Aracaju s Bishop diocese, were created as a result of lack of an official religious process proposed by the Brazilian Republic Proclamation, in 1889. With the appoint to enlarge the number of priests and change the image of the priest married and unrolled who used to identify the Catholic Church in the colonial and imperial Brazil. Such bishops developed into intellectuals in the government, dioceses and formation priest houses. I take as a study object, for this doctorate paper, the academic formation and priesthood developed in theses seminaries, from 1894 to 1933, once 1894 the year of João Pessoa Creation Seminar that was implied the Minor Course (preparation) and the Major one (built by Philosophy and God related studies) and the research limit year of 1933, is concerned about the Major Sergipe Seminary ending, which was created and has worked offering the Minor and Major courses, from 1913 to 1933. Showing the teaching models that guided and leaded the priest formation, referred as Seminaries, and the application result is the objective of this investigation. To comprehend the teaching models seminaries studied, my research line is the Catholic Church theme and priest formation in Brazil. In front of the object and the objective desired, I chose the historical comparative method and the scholars modals notions of Araujo de Barros (2004) and the Sirinelli intellectuals (1996). Such references allowed me to analyze the formation given in the seminary and seminarian participation and actions, included the sequence after the scholars formation. The thesis defended is that the teaching model developed in the Brazilian Seminaries, created after a non official religious process in the Brazilian government, deal with a model of one unique center (Seminary formation and aim pre arranged by Santa Sé), although adapted, presuming the local reality and formation structure (privileged not only spiritual and moral speaking, but intellectual also), was it responsible for intellectuals generations (teachers priests, educationalist priest, journalists priests and so on) that boost the education in Brazil. During the Republic first three decades, when, in thesis, the Government was becoming free religion, i.e., the government did not subsidize the Church anymore, and the Government, among others aspects, did not received any Church care to help the public teaching in the country. The investigation reveled accede, by bishops and their followers, such as by the Concílio de Trento pre concept, or by the others ideas, leading by the priests formation in Seminaries. By creating and stalling diocese Seminary, Bishop Dom Adauto and Dom José went further their functions, by the time they built inside themselves a teaching model thought from the main pedagogic logic, based on several religious exercises, moral and ethic, considered by themselves several knowledge connected to humanity, philosophy and God related studies). Following clearly rationalism principle (the way of teaching, which each subject has its own teacher and this class get together students with the same knowledge, regardless of age) and efficiency (trying to teach the whole content in each class), the Seminaries researched developed a whole education, allowed the structure of a spiritual education, moral and intellectual, for a quality developed by priests, including different levels that they used to performance. Their bottom line, actions and priest matter achievement allowed their broad fulfillment, in the way that priests matter were associated with cultural, educational, welfare assistance, at last, intellectuals

Neste artigo, apresentaremos os principais pontos de minha dissertação de mestrado em andamento, intitulada “Operários e Camponeses. A repercussão da Revolução Mexicana na Imprensa Operária Brasileira (1910-1920)”. Por meio de uma leitura crítica das matérias jornalísticas sobre a Revolução do México que foram publicadas em periódicos da imprensa operária brasileira, no decênio de 1910 até 1920, pretendemos investigar e compreender o impacto desse acontecimento na embrionária classe operária brasileira no início do século XX.
