Intervenção midiática e a cobertura dos Jogos Olímpicos de Pequim/2008: subsídios para a difusão do atletismo

Como todo fenômeno de massa, os acontecimentos esportivos são, atualmente, um dos preferidos da mídia, sobretudo por questões de ordem mercadológica ou simbólica, já que o esporte tem papel fundamental na construção de identidades e subjetividades. Tendo como base este fato, o objetivo desta pesquisa consistiu em identificar como a mídia esportiva refere-se ao atletismo, quando da veiculação de reportagens jornalísticas. Para tanto, foram coletadas reportagens do jornal “Folha de São Paulo”, mais especificamente, do caderno “Pequim/2008” num período de 15 dias antes dos Jogos Olímpicos de Pequim/2008, durante o seu desenvolvimento e 15 dias após o término desse evento, isto é, de 22/07/2008 a 08/09/2008. Nesse período, foram coletadas 49 edições desse jornal, nas quais analisamos 88 reportagens relacionadas ao atletismo. Em revisão bibliográfica e com base na Análise de Conteúdo foram identificadas as principais características dessas reportagens, além dos temas mais recorrentes (unidades de registro) e o contexto (unidades de contexto) de cada uma delas. Foram criados 5 blocos de categorias, a saber: 1. Breves notas informativas sobre o atletismo; 2. Curiosidades acerca do atletismo mundial; 3. Resultados obtidos nas provas do atletismo; 4. Preparação dos atletas e expectativa em relação ao desempenho e 5. Destaques do atletismo nos Jogos Olímpicos de Pequim. A descrição de cada um dos blocos de categorias favoreceu a exposição dos resultados, dentre os quais: a falta de informação que é dedicada ao atletismo pela mídia em períodos em que não ocorrem grandes competições esportivas, a ênfase dada por ela por ocasião de eventos de repercussão internacional e a atenção especial voltada aos atletas que estão no auge da carreira e que, de alguma forma, passam a ser reconhecidos...(Resumo completo, clicar acesso eletrônico abaixo)

O lazer e a difusão da moral protestante

This study of qualitative nature, aimed to investigate the relations arising from experiences in the context of leisure in recreational activities offered in religious camps, with the spread of Protestant moral values .. The study was conducted with the union of literature and exploratory research. First, we sought to understand, through the specific literature, the Protestant society manifestation with its ethics and values, showing how leisure has been sought and appropriated by Protestants institutions. Subsequently, we developed an exploratory research, using as instrument for data collection a mixed questionnaire, applied to a purposeful sample comprised of participants of a religious camp of Protestant institution. Data were analyzed descriptively by Technical Analysis of Thematic Content and indicate that the activities offered at religious camp can diffuse Protestant values directly intentioned, in order to carry religious values so intrinsic to the task, and, indirectly meaning as a tool of evangelism, which are supporting the process of transmission of these values

Entenda RP: campanha de difusão da profissão de Relações Públicas

The profession of public relations presents itself in Brazil currently as a profession in expansion. However, by it’s time of performance, it should already be instated and legitimatized by society like other areas that even though appeared later, are already known and understood. Therefore, this project intends to seek for answers about the current situation, analyzing since it’s appearance in Brazil until now a days. With this analysis of the whole historic trajectory it is possible to understand the many movements that occur today in the area of public relations that are constantly searching for a legitimating and valued profession. However in this context surfaces a paradox: How to value something that is not known? So this project starts up again a campaign of divulgation of public relations promoted by the ABRP (Brazilian Association of Public Relations), now on the internet using the social networks, seeking to have a wider audience, interaction and reach. By this campaign it is possible to show to different publics the existence and relevance of the profession in the Brazilian context in objective and practice way making it more comprehensible in Brazil

Uso das técnicas de difusão em filmes finos por gradiente de concentração (DGT) para avaliação de metais disponibilizados em passivos de mineração de Urânio

The objective of this work is to use the technique of diffusion by concentration gradient films (DGT) for evaluation of dissolved urano in hydro bodies. For this we chose this work as a systems investigation of water bodies in the region of Poços de Caldas, state of Minas Gerais, because, there is a large amount of mining of uranila. The technique to be used to evaluate the potential for dissolved metals analysis involves the use of passive samplers with application in in situ. This allows detection with excellent sensitivity and selectivity allowing the determination of the labile fraction of dissolved metals

Determinação de complexos de urânio em solo usando a técnica de difusão em filmes finos por gradiente de concentração (DGT)

This paper proposes to assess the lability of complexes of uranium in soil using the technique of Diffusion in Thin Films by concentration gradients (DGT) in the vicinity the Osamu Utsumi mine, located in the municipality of Caldas - MG. The technique is based on the 1ª Fick Law, where metal complexes diffuse through a gel, which in turn is adsorbed on a resin. The metals adsorbed are recovered by an analytical technique and quantified by optical emission spectrometer with plasma inductively coupled (ICP-OES) or mass spectrometry with inductively coupled plasma (ICP-MS)

Desenvolvimento e validação do método de difusão em ágar para quantificação de fluconazol cápsulas e aplicação em estudos de estabilidade

O fluconazol é um antifúngico de amplo espectro indicado para o tratamento de infecções fúngicas sistêmicas e superficiais. A determinação da potência dos antimicrobianos é importante no controle e na garantia da qualidade das preparações farmacêuticas e faz-se necessário o desenvolvimento de procedimentos práticos e econômicos que possam ser validados e aplicados no doseamento desses fármacos. Dentre os ensaios microbiológicos, os mais comumente empregados são o de difusão em ágar e o turbidimétrico. O objetivo deste trabalho foi desenvolver e validar métodos microbiológicos para determinação da potência do fluconazol cápsulas. O método de difusão em ágar foi desenvolvido empregando ágar Sabouraud e Candida albicans ATCC 64548 como micro-organismo teste. Foi utilizado o delineamento 3 x 3, segundo preconiza a Farmacopeia Brasileira (2010). A validação do método demonstrou linearidade entre o diâmetro dos halos de inibição e o logaritmo da concentração numa faixa de 25,0 a 100,0 µg/mL. Os resultados foram precisos, com desvio padrão relativo igual a 6,15%, e exatos, com intervalo de tolerância de 97,30%, dentro dos limites permitidos. O método foi aplicado ainda em estudos de estabilidade, nas condições de estresse calor úmido, em câmara climática a 40 ºC e 75% de umidade relativa por 90 dias; calor seco, em estufa a 60 ºC por 66 dias e fotodegradação, em câmara espelhada com luz UVC por 66 e 180 dias. Os valores de teor médio calculados foram de 30,27% para calor úmido; 27,72% para calor seco; 33,29% para fotodegradação durante 66 dias e 25,00% para fotodegradação durante 180 dias

Estudo da superfície de fibras de carbono após tratamento de implantação iônica por imersão em plasma (3IP)

In this work, plasma immersion ion implantation (PIII) treatments of carbon fibers (CFs) were performed in order to induce modifications of chemical and physical properties of the CF surface aimed to improve the performance of thermoplastic composite. The samples to be treated were immersed in nitrogen or air glow discharge plasma and pulsed at −3.0 kV for 2.0, 5.0, 10.0, and 15.0 min. After PIII processing, the specimens were characterized by atomic force microscopy (AFM), scanning electron microscopy, Raman spectroscopy, and X-ray photoelectron spectroscopy (XPS). After CFs treatments, the CF/Polypropylene (PP) composites were produced by hot pressing method. Surface morphology of as-received CFs exhibited some scratches aligned along the fibers due to the fiber manufacturing process. After both treatments, these features became deeper, and also, a number of small particles nonuniformly distributed on the fiber surface can be observed. These particles are product of CF surface sputtering during the PIII treatment, which removes the epoxy layer that covers as-received samples. AFM analyses of CF samples treated with nitrogen depicted a large increase of the surface roughness (Rrms value approximately six times higher than that of the untreated sample). The increase of the roughness was also observed for samples treated by air PIII. Raman spectra of all samples presented the characteristic D- and G-bands at approximately 1355 and 1582 cm−1, respectively. Analysis of the surface chemical composition provided by the XPS showed that nitrogen and oxygen were incorporated onto the surface. The polar radicals formed on the surface lead to increasing of the CF surface energy. Both the modification of surface roughness and the surface oxidation contributed for the enhancement of CF adhesion to the polymeric matrix. These features were confirmed ...

Fadiga axial do aço inoxidável 15-5 PH tratado pela implantação iônica por imersão em plasma

When materials for application in aircraft structural components are studied, it must be considered that they will be submitted to cyclic loading, and this is an important parameter to design the study in fatigue life of the materials. Whereas, for example, a landing gear operation, the study of fatigue life and corrosion in the materials used in it is essential, especially when you want to use new techniques for surface treatments. The objective is to study the influence of surface treatment of immersion ion implantation nitrogen plasma, in axial fatigue of Stainless steel 15-5 PH in 39-42 HRC condition. Stainless steel 15-5 PH was tested in axial fatigue and corrosion in salt spray. It was also performed microindentation tests, optical microscopy for microstructural analysis and scanning electron microscopy for fractographic analysis. It was observed that the 3IP had no effect on the thickness of the material and not the hardness of it, and still provided a significant increase in fatigue life of the material

Estudo da superfície do carbono vítreo reticulado após tratamento de implantação iônica por imersão em plasma (3IP) para a obtenção de eletrodos

In this work, RVC samples were treated by plasma immersion ion implantation (PIII) for electrodes production. High-voltage pulses with amplitudes of -3.0 kV or -10.0 kV were applied to the RVC samples while the treatment time was 10, 20 and 30 minutes. Nitrogen, atmospheric air and H2:N2 mixture were employed as plasma sources. The samples were characterized by scanning electron microscopy (SEM), X-ray photoelectron spectroscopy (XPS) and electrochemical measurements. The SEM images present an apparent enhancement of the surface roughness after the treatment probably due to the surface sputtering during the PIII process. This observation is in agreement with the specific electrochemical surface area (SESA) of RVC electrodes. An increase was observed of the SESA values for the PIII treated samples compared to the untreated specimen. Some oxygen and nitrogen containing groups were introduced on the RVC surface after the PIII treatment. Both plasma-induced process: the surface roughening and the introduction of the polar species on the RVC surface are beneficial for the RVC electrodes application

As contribuições de Júlio Pires Porto-Carrero à difusão da psicanálise de crianças no Brasil nas décadas de 1920 e 1930

The ideas related to the psychoanalysis of children began to be disseminated in Brazil in the 1920’s, by professionals connected to medicine and education. Therefore, the present article aims showing the contributions of Julius Pires PortoCarrero in the introduction of ideas referred to psychoanalysis of children in Brazil from 1920 to 1930, focusing on education. Through bibliographic research all of the author´s work that used psychoanalytic ideas to discuss themes related to education were identified. The conclusions indicate that, in agreement with new educational proposals emerged in the country in the 1920s, the author devoted himself to spread psychoanalytic concepts among educators, assuming that a better understanding of the child based on psychoanalysis could support its development and also the learning process. Besides conferring social legitimacy to psychoanalysis, this initiative has enabled the arising of a more comprehensive practice in child psychoanalysis.
