Partir e ficar : Dinâmicas nos processos de migraçao e imigraçao no norte de Minas Gerais- Brasil

This proposal assumes that the migration process is a socio-spatial process. Where desires, goals, fears and hopes of migrating become identities, social constructs that ultimately lead to ways of belonging. Place is a form of interaction, whether between man and the environment, or the man with a specific space. Place demand belonging. Belonging demand identity. Migration then became a strategy, a resistance, an eternal possibility or impossibility of staying or leaving. The displacements eventually cause changes in the relationships and interactions of individuals in their most different spaces. In this sense, they grasp the shifting process of an individual or social group, it is seen that migration and immigration is a process beyond "of being in different social spaces", is a mode of social reproduction defined in relations of time and space, emphasizing the duality of being in motion. Therefore, this proposal seeks to emphasize the dynamics of migration and immigration process in their contexts, as well as highlight the economic social constructions arising from these proceedings, in its social, cultural, political and, thus characterizing the various identities of individuals

Associaçoes comunitárias do meio rural : Um estudo de caso no centro oeste de Minas Gerais

This paper examines the association in a rural mining town in Brazil. The results belong to a master dissertationin Rural Extension on membership organizations and public policies for rural areas aiming to identify the roles performed by membership organizations, the reasons that explained their formation and their relationship with policy making for rural areas in the case studied. It is a case study, for which interviews were conducted with representatives of the organizations in order to deepen into the issues related to their historical, the roles they play and how and whether they participate in development project proposals. The results revealed anup-down process of formation of rural organizations, being created as bargaining tools for achieving collective benefits, reproducing dependency relationships

Non contact inspection of the fatigue damage state of carbon fiber reinforced polymer by optical surface roughness measurements

This work presents the evaluation of a new non-contact technique to assess the fatigue damage state of CFRP structures by measuring surface roughness parameters. Surface roughness and stiffness degradation have been measured in CFRP coupons cycled with constant amplitude loads, and a Pearson?s correlation of 0.79 was obtained between both variables. Results suggest that changes on the surface roughness measured in strategic zones of components made of the evaluated CFRP, could be indicative of the level of damage due to fatigue loads. This methodology could be useful for other FRP due to similarities in the fatigue damage process.

Optical sensing of the fatigue damage state of CFRP under realistic aeronautical load sequences

We present an optical sensing methodology to estimate the fatigue damage state of structures made of carbon fiber reinforced polymer (CFRP), by measuring variations on the surface roughness. Variable amplitude loads (VAL), which represent realistic loads during aeronautical missions of fighter aircraft (FALSTAFF) have been applied to coupons until failure. Stiffness degradation and surface roughness variations have been measured during the life of the coupons obtaining a Pearson correlation of 0.75 between both variables. The data were compared with a previous study for Constant Amplitude Load (CAL) obtaining similar results. Conclusions suggest that the surface roughness measured in strategic zones is a useful technique for structural health monitoring of CFRP structures, and that it is independent of the type of load applied. Surface roughness can be measured in the field by optical techniques such as speckle, confocal perfilometers and interferometry, among others.

Geochronological evidence for pervasive miocene weathering, Minas Gerais, Brazil

Ar-40/Ar-39 laser incremental-heating analyses of 22 individual grains of supergene cryptomelane from three weathering profiles, up to 400 km apart, in the Rio Doce valley and Barbacena regions at Minas Gerais, Brazil, show that the formation of weathering profiles in these regions is contemporaneous, suggesting a strong weathering event in the Middle to Late Miocene (10-8 Ma). The preservation of these Miocene samples at or near the present surface suggests that either erosion rates have been very low in the region since the Miocene or that a much thicker weathering mantle was present in the region originally. Assuming a constant thickness of weathering profiles in the region throughout the Tertiary, we may calculate weathering front propagation rates of 4-8 m Myr(-1) during the past 10 Ma.

40Ar/39Ar geochronology constraints on late miocene weathering rates in Minas Gerais, Brazil

Ar-40/Ar-39 incremental heating ages for twenty one grains of cryptomelane, collected at 0, 42, 45, and 60 in depths in the Cachoeira Mine weathering profile, Minas Gerais, permit calculating long-term (10 Ma time scale) weathering rate (saprolitization rate) in SE Brazil. Pure well-crystallized cryptomelane grains with high K contents (3-5 wt.%) yield reliable geochronological results. The Ar-40/Ar-39 plateau ages obtained decrease from the top to the bottom of the profile (12.7 +/- 0.1 to 7.6 +/- 0.1 Ma at surface; 7.6 +/- 0.2 to 6.1 +/- 0.2 Ma at 42 m; and 7.1 +/- 0.2 to 5.9 +/- 0.1 Ma at 45 in; 6.6 +/- 0.1 to 5.2 +/- 0.1 Ma at 60 in), yielding a weathering front propagation rate of 8.9 +/- 1.1 m/m.y. From the geochronological results and the mineral transformations implicit by the current mineralogy in the weathering profiles, it is possible to calculate the saprolitization rate for the Cachoeira Mine lithologies and for adjacent weathering profiles developed on granodiorites and scbists. The measured weathering front propagation rate yields a saprolitization rate of 24.9 +/- 3.1 t/km(2)/yr. This average long-term (> 10 Ma) saprolitization rate is consistent with mass balance calculations results for present saprolitization rates in weathering watersheds. These results are also consistent with longterm saprolitization rates estimated by combining cosmogenic isotope denudation rates with mass balance calculations.

INFLUÊNCIA DA APRENDIZAGEM ORGANIZACIONAL NA INOVAÇÃO DE PRODUTOS: ESTUDO EM EMPRESAS DE BASE TECNOLÓGICA DO VALE DA ELETRÔNICA, EM MINAS GERAIS

Esse estudo investiga como a aprendizagem organizacional pode influenciar a inovação em produtos nas empresas de base tecnológica. As empresas estudadas estão localizadas no Arranjo Produtivo Local Eletroeletrônico, conhecido informalmente como Vale da Eletrônica, na cidade de Santa Rita do Sapucaí, Minas Gerais. O arcabouço teórico envolve a exploração dos temas principais: aprendizagem organizacional e inovação. A decisão em estudar algumas empresas localizadas nessa cidade se deu por este ambiente ser composto de uma estrutura voltada à produção de conhecimentos tecnológicos dotados de inovações. Como objetivos específicos, esta pesquisa busca identificar as formas, fontes e o processo de aprendizagem organizacional que influenciaram as inovações apresentadas pelas empresas. Trata-se de uma pesquisa qualitativa, de caráter exploratório e descritivo. Os dados empíricos foram coletados por meio de entrevistas semiestruturadas a proprietários e gestores das empresas. O resultado evidenciou que formas e fontes internas e externas de aprendizagem e a proximidade da academia como coadjuvante no desenvolvimento das inovações contribuíram e influenciaram a inovação de produtos responsáveis pelo aumento de vantagem competitiva nas empresas. Esse estudo também permitiu apontar a relevância e a contribuição da aprendizagem organizacional na inovação de produtos e abre caminhos para estudos em outras empresas de base tecnológica.
