Estudo dos estereótipos que a revista regional Beach&Co fez do caiçara - povo nativo que mantém uma cultura relacionada ao mar e a mata nas cidades de Caraguatatuba, São Sebastião, Ubatuba e Ilhabela, no Litoral Norte Paulista. Aplicou-se uma metodologia de caráter híbrido que mesclou os Estudos Culturais com base nas obras de Douglas Kellner, Stuart Hall e Raymond Williams com a Análise de Discurso nas obras de Dominique Maingueneau, Eni Orlandi, Patrick Charaudeau e Audre Alberguine. Também foram resgatados os estudos da Cultura Caiçara feitos por Carlos Diegues, Gioconda Mussolini, Emilio Willems, e por fim redefiniu-se o gênero jornalístico Reportagem e contextualizou-se o Jornalismo Regional de Revista. Posteriormente, analisou-se a primeira década da revista Beach&Co, totalizando 120 edições publicadas de janeiro de 2002 a junho de 2012, no qual foram mostradas as diversas abordagens que a publicação fez do caiçara, bem como a evolução da própria revista nos aspectos editoriais, comercial e de design gráfico. Em seguida, selecionou-se 23 reportagens nas editorias de turismo, gastronomia, esportes e outras relacionadas à Cultura Caiçara, que tiveram seus discursos semânticos e os elementos valorativos de linguagens analisados. Nas conclusões, constatou-se que a cobertura jornalística da Beach&Co privilegia as áreas do turismo e do desenvolvimento do Litoral Norte e Baixada Santista; que a revista passou por readaptações e esquematismos dominantes na produção jornalística e encontrou mercado nas especificidades do Litoral Paulista; a Beach&Co se consolidou como uma revista regional profissional, de qualidade e criativa, distante do amadorismo, do bairrismo e da mimetização simplista; apesar de muitas vezes ter usado o caiçara para adjetivar os aspectos turísticos e gastronômicos do Litoral Norte, a revista trabalhou a produção simbólica do caiçara de forma ampla e retratou vários aspectos da Cultura Caiçara, reforçando o poder desta revista regional, como retroalimentando os sotaques do Litoral Paulista nas demais regiões do país onde a publicação também é lida.

Este trabalho aborda a notícia cultural. Trata-se de um estudo comparativo entre o jornal e a TV, enfocando como estes diferentes suportes veiculam notícias culturais. Pretendeu-se traçar o perfil do que atualmente é noticiado no âmbito cultural em dois produtos noticiosos voltados para a cobertura de eventos e produtos culturais um impresso e outro televisionado. Para examinar esta questão comparamos o que foi publicado no caderno Ilustrada (Jornal Folha de S. Paulo) e editado no Programa Metrópolis (TV Cultura) no período de 10 a 15 de dezembro de 2001. A amostra incluiu sete edições do Metrópolis 41 matérias analisadas , e sete da Ilustrada 86 matérias. Ao analisar estes veículos percebemos que a TV e o jornal têm mostrado comportamentos diversos. Um exemplo desta diversidade se dá na escolha de eventos e fatos a serem noticiados o jornal parece enfocar, prioritariamente, eventos que podem ser considerados como pertencentes à cultura massiva, enquanto a TV veicula, com grande incidência, eventos da chamada cultura erudita. Torna-se necessário enfatizar que nossas conclusões não podem ser generalizadas nem para outros períodos do Caderno Ilustrada e do Programa Metrópolis e muito menos para os jornais e as televisões como um todo.

The demand for materials with high consistency obtained at relatively low temperatures has been leveraging the search for chemical processes substituents of the conventional ceramic method. This paper aims to obtain nanosized pigments encapsulated (core-shell) the basis of TiO2 doped with transition metals (Fe, Co, Ni, Al) through three (3) methods of synthesis: polymeric precursors (Pechini); hydrothermal microwave, and co-precipitation associated with the sol-gel chemistry. The study was motivated by the simplicity, speed and low power consumption characteristic of these methods. Systems costs are affordable because they allow achieving good control of microstructure, combined with high purity, controlled stoichiometric phases and allowing to obtain particles of nanometer size. The physical, chemical, morphological, structural and optical properties of the materials obtained were analyzed using different techniques for materials characterization. The powder pigments were tested in discoloration and degradation using a photoreactor through the solution of Remazol yellow dye gold (NNI), such as filtration, resulting in a separation of solution and the filter pigments available for further UV-Vis measurements . Different calcination temperatures taken after obtaining the post, the different methods were: 400 º C and 1000 º C. Using a fixed concentration of 10% (Fe, Al, Ni, Co) mass relative to the mass of titanium technologically and economically enabling the study. By transmission electron microscopy (TEM) technique was possible to analyze and confirm the structural formation nanosized particles of encapsulated pigment, TiO2 having the diameter of 20 nm to 100 nm, and thickness of coated layer of Fe, Ni and Co between 2 nm and 10 nm. The method of synthesis more efficient has been studied in the work co-precipitation associated with sol-gel chemistry, in which the best results were achieved without the need for the obtainment of powders the calcination process

The unbridled consumption of electronic equipment associated with fast immersion of new technologies on the market leads to the accelerated growth of electronic waste. Such waste mostly contains printed circuit boards in its structure. Printed circuit boards have many metals, including heavy metals, being highly toxic. Electronic waste is discarded improperly and indiscriminately, usually without any previous treatment and with other municipal waste, contaminating the environment and causing serious problems to human health. Beyond these metals, there are also precious metals and high value-added basis, that can be recovered and recycled, reducing the exploration of natural resources. Thus, due to the high growth potential and reuse of these waste treatment processes, characterization and separation were applied to the printed circuit boards. The printed circuit boards were subjected to physical treatments such as dismantling, crushing, sizing separation, magnetic separation and chemical treatments such as pyrolysis and leaching. Through characterization process (pyrolysis and leaching) the proportions of the components of the granulometric range were determined: 46,08% of metals; 23,32% of polymers and 30,60% of ceramics. It was also observed by particle size separation that metal components tend to concentrate in coarse fractions, while polymeric and ceramic components in fine fractions. From the magnetic separation process was obtained 12,08% of magnetic material and 82,33% of non-magnetic material.

Welding is one of the most employed process for joining steel pipes. Although, manual welding is still the most used one, mechanized version and even automatized one have increased its demand. Thus, this work deals with girth welding of API 5L X65 pipes with 8” of nominal diameter and 8.0 mm thickness, beveled with V-30º narrow gap. Torch is moved by a bug carrier (mechanized welding) and further the parameters are controlled as a function of angular position (automatized welding). Welding parameters are presented for filling the joint with two-passes (root and filling/capping passes). Parameters for the root pass were extracted from previous author´s work with weldments carried out in plates, but validated in this work for pipe welding. GMAW processes were assessed with short-circuit metal transfer in both conventional and derivative modes using different technologies (RMD, STT and CMT). After the parameter determination, mechanical testing was performed for welding qualification (uniaxial tension, face and root bending, nick break, Charpy V-notch impact, microhardness and macrograph). The initially obtained results for RMD and CMT were acceptable for all testing and, in a second moment, also for the STT. However, weld beads carried out by using the conventional process failed and revealed the existence of lack of fusion, which required further parametrization. Thus, a Parameter-Variation System for Girth Welding (SVP) was designed and built to allow varying the welding parameters as a function of angular position by using an inclinometer. The parameters were set for each of the three angular positions (flat, vertical downhill and overhead). By using such equipment and approach, the conventional process with parameter variation allowed reducing the welding time for joint accomplishment of the order of 38% for the root pass and 30% for the filling/capping pass.
