Avaliação das técnicas de soldagem MIG-P CA e MIG-P CC+ aplicadas ao passe de enchimento em liga de alumínio AA5083

For contain beneficial properties, aluminum alloys are gaining more importance in different industrial areas, becoming the subject of study in several academic fields. When related to welding these alloys have some peculiarities that may hinder the union, such as microscopic oxide layer present on the metal surface. The MIG welding process, also known as GMAW, has developed versions that can be effective for welding aluminum. Knowing this, for this paper, two versions of pulsed MIG (CC + and CA) were chosen to evaluate which best suits pass by filling bevel on AA5083 aluminum sheets with 8 and 12 mm thick respectively. Furthermore, two types of wire, ER5087 and ER5183 were evaluated. To evaluate the process and versions of the wires, the high-speed cameras and thermal were used to monitor the metal transfer and the thermal behavior respectively, and the metallographic analysis for macrographic view of the weld beads and non-destructive testing by radiography for observation of possible discontinuities. It was found that the technique of MIG-P CA showed better results ahead of another technique both welding conditions imposed. When connected to the wires, they showed similar results, with uniform cords and seamless

Desejo, estilo de vida e transgressão da identidade em Dancer from the dance de Andrew Holleran e Pela noite de Caio F.

From the research and awareness of literary work, this thesis discusses aspects related to the study of homoeroticism and lifestyles in the works Dancer from the Dance (2001) by Andrew Holleran and Pela noite (2010) by Brazilian author Caio Fernando Abreu. Whereas issues about beauty, desire and lifestyle shape cutouts important to the narrative, I propose a discussion by examining the works that mark from the first moments of sexual release party in New York with the peculiarities of their own styles that characterized the Andrew Holleran characters rostificadas by an ethos that he composed during this time opening for freedom of sexual deviant sexualities. In Pela noite, we reiterate a continuation of opening moment in Brazil for gay characters Caio , assuming the early 1980s for those characters is the first " shadows " of AIDS and knowledge of self , in which his characters living with fear, anonymity and reminiscences of homophobia as a backdrop to the discussions that are triggered off by the author . To compose a theoretical framework to subsidize this work , we selected the works of Michel Foucault (2007 , 2010a , 2010b ) , Eve Kosofsky Sedgwick (2008 ) , Didier Eribon (2008 ) , David Cartier (2004 ) , David Eisenbach (2006 ) and other contributions that were undoubtedly essential to this endeavor

Eu tenho os meus direitos: análise de audiências de conciliação em um JECRIM de Natal

This research aims at examining, within the scope of Legal Anthropology, the constitution processes of Criminal Small-Claims Courts-JECRIMs in Brazil seeks to discuss, from the making of ethnographic work, the relationship between forms and dynamics of Justice distribution both at national and local level. To do so, one performed an ethnography at a JECRIM in the city of Natal, analyzing resulting peculiarities arising from the works the Judge-Coordinator and all of the other Judicial Actors in order to bring to reality the proposals of Law 9.099/95. Such ethnography has also enabled the analysis of the interactions between both Judicial Actors and Claimants, with or without private attorneys. The theoretical framework included several topics, including processes of conflict legalization, performance and representation analysis, and relationships between law, morality, feeling and ritual. One sought to a critical reading of the current state of conciliation and mediation, taking into account both legal and theoretical parameters on the subject. At the end, a general guideline of State action in conflict management is drawn, revealing some aporias and contradictions when voluntary processes are made mandatory by the State-Punisher.

Mestrado profissional em saúde da família: o curso sob a perspectiva dos mestrandos

Professional masters were created in Brazil in the 1990s in response to social changes in the world of work and aim to train high-level professionals with own profile for various activities of society and the productive sector. They are up in more innovative mode of graduate studies in Brazil, and therefore lack of legitimacy of their identity, which raises the need for discussions to get further information and outline the characteristics of this postgraduate modality. You want to build new understandings about their peculiarities starting from the perspective of students from the Professional Masters in Health Net Northeast Family Training in Family Health, and not only according to the similarities and differences with the academic master. This study aims to understand the meanings attributed by masters training in that course. This is a qualitative, exploratory study. The subjects are 100 students in training in 2013, distributed among the six institutions nucleation Network Northeast Training in Family Health. To collect information desk research was conducted in institutional records of all students, as well as interviews. We interviewed 15 students, distributed in the six nucleation institutions. Information obtained through recorded interviews were transcribed and resulted in two analytical corpus subsequently submitted to Alceste © 4.9 software for identification of semantic classes. It can be concluded that the course provided a redefinition of professional practices in the Family Health Strategy, considering the organizational context of primary care in the Northeast and the specifics of the health work. Even before the student body difficulties related to ownership of research methods, and the very active methodology of problem-based learning, the course effectively contributed to the improvement of work processes in primary care, valuing teamwork and allowing the acquisition of new scientific knowledge.

O envelhecimento no espaço midiático: a produção de sentidos pelos meios jornalísticos

Aging as a social phenomenon is guided in the ways of production and reproduction, that is linked to the peculiarities and compliances of the social structure influence the values and erected senses. The search for the understanding of the reality will be given by the appropriation of knowledge/information that in contemporary times are increasingly tied to the media means, so that they go beyond the mere condition media, reaching the condition of instruments of direct, attitudes and opinions production. Among the media instruments, there are news medias, that are important means of information dissemination and consequently production of senses, including over aging. Thus, the objective is to: apprehend the social representations and meanings associated with aging in the media space about aging; browse the social representations about aging in media space and their influence on the relations that are established in the cultural socio-economic context. To do it The Theory of Social Representation will be used. To collect the data, 57 online news from the three main state newspapers were studied: Tribuna do Norte, Gazeta do Povo and Jornal de Hoje, which were captured through a search tol of these newspaper sites, using the words: “aging””elderly”. These materials were analyzed making use of Bardin’s Qualitative Analysis, which allowed the establishment of five categories, namely: Aging and violence; Aging in contemporary times; Aging and health; Aging and citizenship; and Aging, work and action. In the first category news reporting violent situations are framed the regardless of the victim’s condition or the one charged by the violence, the fragility of elderly persists. In Aging in contemporary times the attempts of the news media to explain the demographic changes of the quantitative increases in the elderly, the burden it may lead to the full development of the country are noticed. In Aging and health is noticed the imminent end of the condition brought on age, as a synonym for diseases and conditions. In the fourth category, Aging and citizenship situations are shown where peculiarities and needs or the elderly need to turn into obligation to be fulfilled, denouncing the condition of low expression and social power of the class. Finally, in Aging, work and action situations that indicate the non-expectation of elderly interaction with new technologies and participation in decision-making directions of society are brought. In a general and specific form this analysis allowed learning the ways of production of meanings about aging in the papers, as these ones tend to represent aging through intentioned situations as hegemonic needs, building the social representation of the elderly as fragile person, submissive, inactive, subject to violence and susceptible to becoming ill.

A produção textual no ensino fundamental: processo de retextualização com o gênero memórias

Teaching Portuguese language in Brazilian public schools is still limited mostly to studying decontextualized text fragments, memorizing classifications and cult of grammar rules. Considering the language as a social, cultural practice which emerges from the intersubjective interaction, we sought to propose an educational intervention that prioritizes the retextualization processes from speech to the writing of memoirs as a textual genre, so as to contribute for improving learner’s discursive performances. Therefore, paying attention to these concerns and in attempt to contribute for improving the teaching of Portuguese language in elementary school, we chose as privileged locus a 9th grade class from a state school in Bento Fernandes, RN. The corpus is formed by texts produced and retextualized by students from the elders’ oral reports within local community. We sought thus to understand what memory is, its importance for registering local spoken language and culture, as much as to carry out didactic actions that favor students’ learning in the activities of textual production. In light of the theoretical overviews about linguistic-discursive relations, based on Marcuschi’s (1993, 1997, 2001, 2002, 2006, 2008, 2010) conception of oralitiy-writing continuum and the debates proposed by Antunes (2003, 2014), Alves Filho (2011), Koch (2012) and Bakhtin (1992, 2011), we aimed to understand, by analyzing the retextualized memoirs, how these practices complement each other within the process of orality and writing. As for the proposal of didactic sequences, the study has been oriented by Dolz and Scheneuely (2004); as for the memoirs, by the guidelines of Coracine and Ghiraldelo (2011) and Le Goff (2010, 2013). In this way, this work followed the action-research methodology in a qualitative approach, considering the teacher (researcher) as an active agent involved in the process of knowledge production in his own educational practice, so as to interfere in the mediation, knowledge production and its dissemination in classroom context, which is the privileged locus for constructing and transforming process. There is much to be research within the area of retextualization. Yet we verified that this educational intervention, based on discursive operators of retextualization, has been proven viable as an efficient path so that we teachers can work the peculiarities of usages and functions of textual genres in oral and written modalities of a language, without grasping both as a dichotomy. This accredited us to strengthen a discourse that undoes many myths still present in that order, especially the one that causes more damage for the learners of Portuguese language – that writing is a representation of speech.

Iron speciation and magnetic susceptibility in bottom sediments of the Black Sea, Core SMG91-903

12 cores of Late Pleistocene - Holocene deposits were studied. They were collected by gravity cores on the continental slope and in the deep-water part of the Black Sea within the Adler-Tuapse polygon. In four of them in New Euxinian deposits at the base of a packet of hydrotroilite laminae paleomagnetic anomalies likely resulting from the Gothenburg magnetic excursion occur. Comparison with results of similar studies in the western Black Sea, where the Gothenburg magnetic excursion was previously found, let to validate stratigraphic synchronism of the hydrotroilite horizon in the eastern and western parts of the Black Sea and to confirm the authors' views about peculiarities of paleogeographical development of the Black Sea basin in the Late Pleistocene - Holocene.

(Table 1) Composition of organic matter from sediments of the triple junction area in the Indian Ocean

Bituminous substances in metalliferous sediments from the region of the triple junction in the Indian Ocean were studied. Specific peculiarities of their structure confirming location in "hot conditions" were revealed. Hydrocarbons are genetically connected with hydrothermal matter, and thus they could be considered as a geochemical indicator of hydrothermal processes in the ocean.

A dinâmica da taxa de câmbio no Brasil face às operações swap (2002-2015)

This dissertation investigates, based on the Post-Keynesian theory and on its concept of monetary economy of production, the exchange rate behavior of the Brazilian Real in the presence of Brazilian Central Bank's interventions by means of the so-called swap transactions over 2002-2015. Initially, the work analyzes the essential properties of an open monetary economy of production and, thereafter, it presents the basic propositions of the Post-Keynesian view on the exchange rate determination, highlighting the properties of foreign exchange markets and the peculiarities of the Brazilian position into the international monetary and financial system. The research, thereby, accounts for the various segments of the Brazilian foreign exchange market. To accomplish its purpose, we first do a literature review of the Post-Keynesian literature about the topic. Then, we undertake empirical exams of the exchange rate determination using two statistical methods. On the one hand, to measure the volatility of exchange rate, we estimate Auto-regressive Conditional Heteroscedastic (ARCH) and Generalized Auto-regressive Conditional Heteroscedastic (GARCH) models. On the other hand, to measure the variance of the exchange rate in relation to real, financial variables, and the swaps, we estimate a Vector Auto-regression (VAR) model. Both experiments are performed for the nominal and real effective exchange rates. The results show that the swaps respond to exchange rate movements, trying to offset its volatility. This reveals that the exchange rate is, at least in a certain magnitude, sensitive to swaps transactions conducted by the Central Bank. In addition, another empirical result is that the real effective exchange rate responds more to the swaps auctions than the nominal rate.

A pedagogia industrial da FIEMG: um estudo sobre o pensamento empresarial a partir da revista vida industrial (1961-1974)

The present research results of the studies and debates inherent in PhD in Education at the Graduate Program in Education at the Federal University of Uberlândia, belonging to the Research Line "Politics and Knowledge in Education." This thesis aims to analyze the contradictory meaning of education as training human history, specifically educational representative under the logic of the industrial business associated FIEMG (Federation of Industries of the State of Minas Gerais) in the context 1961-1974. This definition is justified by the historical fact that it was a period marked by the cyclical crises of capital and their impacts in the final phase of the industrialization process in Brazil: it starts with one of the apexes of economic growth in the country , driven by national developmental , continues with a severe political crisis in 1966 , also impacting the economic sphere, and finally, with the constant quest for economic stability even under high prices, hatch the factors that led to the Brazilian economy to the context of the "Economic Miracle". For this, it was necessary to link the debate between education and work from the perspective of historical materialism and dialectical their subsidies theoretical-methodological and epistemological. In the first chapter, we designed a "State of the art" category "human formation", conceived as a process of education and history, from the Marxist assumptions, aiming at the reconstruction of concepts and meanings of which is the formation of workers in contradictory logic, the bias of comprehensive training and the prospect of capital accumulation. Then, in the second chapter, we present a review about industrialization, the industrial business and its development perspective 1961-1974. The third chapter was established on a contextualization of the state and its peculiarities, the industrial business and its proposed development both nationally and at the state (Minas Gerais). Finally, in the fourth chapter, was organized dialogue with the sources, from a historical survey of the shares of the industrial business with an emphasis on education, which converged in a pedagogy industrial consolidation in line with the political and economic conditions specific period from 1961 to 1974. It has mailing bibliographic reference business thinking expressed in the concreteness of training workers and industry of Minas Gerais, in agreement with the demands of work and training of mining companies. The thesis of this study is the defense that the corporate actions which constituted pedagogy industrial concepts were articulated to political and economic development in Brazil, since the discipline to work imposed by such conceptions met the human worker training geared to the accumulation the general capital and industrial capital in particular. Establish, therefore, different logics, the state level, the scope of private foreign capital and domestic private capital, which came up the process of capital accumulation, loading, contradictorily, the possibilities of building the human beyond capital, or a teaching job.

Saint, martyr, killer of Christ? The legend of Longinus in medieval Irish tradition

This dissertation is the first comprehensive and synthetic study of the Irish presentation and legends of Longinus. Longinus was the soldier at the crucifixion who pierced Christ with a spear, who believed and, according to some texts, was healed of his blindness by the blood and water issuing from the wound, and who later was martyred for his belief. In my thesis I survey the knowledge and use of the legend of Longinus in Ireland over genres and over time. Sources used for the analyses include iconographic representations of the spear-bearer in manuscripts, metalwork and stone and textual representations of the figure of Longinus ranging over the history of Irish literature from the early medieval to the early modern period, as well as over Irish and HibernoLatin texts. The thesis consists of four core chapters, the analyses of the presentations of Longinus in early-medieval Irish texts and in the iconographic tradition (I,II), the editions of the extant Irish and the earliest surviving Latin texts of the Passion of Longinus and of a little-known short tract describing the healing of Longinus from Leabhar Breac (III), and the discussion of the later medieval Irish popular traditions (IV). Particular attention is given to the study of two intriguing peculiarities of the Irish tradition. Most early Irish Gospel books feature an interpolation of the episode of the spear-thrust in Matthew 27:49, directly preceding the death of Christ, implying its reading as the immediate cause of death. The image of Longinus as 'iugulator Christi' ('killer of Christ') appears to have been crucial for the development of the legend. Also, the blindness motif, which rarely features in other European popular traditions until the twelfth century, is attested as early as the eighth century in Ireland, which has led some scholars to suggest a potential Irish origin.

Mediation and the Social Work profession: particularly in the community context

In 2008, the European Union published its Directive on mediation in civil and commercial matters, offering general regulation of this conflict resolution system, its principles, and its objectives. Social workers have for some time defended their role as mediators, but this reality has changed and mediation appears to have taken shape as an independent profession due to existing regulation, its introduction to universities and the implementation of training courses. This article analyses the differences between the two professions: mediator and social worker. It also considers the mediation that is carried out in the community context. Community mediation is a perfect tool for achieving a changed understanding of public social services, seeking to encourage citizens to participate in and take responsibility for community life and thereby to become active citizens as envisaged by the 2012 Global Agenda for Social Work. However, mediation in this context has certain peculiarities, and at times confusion may arise between the figures of social worker and mediator.
