RESUMO O estudo analisa, sob a ótica da Psicodinâmica do Trabalho, a dinâmica do reconhecimento e as estratégias utilizadas pelos bombeiros militares do Rio de Janeiro ante as negociações por melhores salários e condições de trabalho. Trata-se de um estudo qualitativo, com utilização de entrevistas tratadas por meio de análise temática. Os resultados apontaram que a falta de reconhecimento pode desencadear sofrimento para o trabalhador e afetar a sua saúde. Os bombeiros militares, no diálogo com os gestores, utilizaram uma estratégia coletiva ao mobilizar a população, que, por meio do julgamento de utilidade, expressou o reconhecimento simbólico capaz de impulsionar as negociações.

ABSTRACT The study analyzes from the perspective of work psychodynamics, the dynamics of the acknowledgement and the strategies used by firefighters in Rio de Janeiro before the negotiations for better wages and work conditions. This is a qualitative study, using interviews treated through thematic analysis. The results pointed that the lack of acknowledge can develop suffering for workers and affect their health. The military firemen, in dialogue with the managers, used a collective strategy to mobilize the population, which, through the judgment of usefulness, expressed the symbolic recognition that is able to boost negotiations.

Introduction The prognosis of dengue depends on early diagnosis and treatment, which can help prevent severe forms whose characteristics were evaluated here. Methods A cross-sectional study was conducted involving dengue cases in Vitória, State of Espírito Santo, Brazil, in 2011. Results Two health regions registered 56.3% of 371 cases of severe dengue. Of these cases, 21.3% presented with dengue hemorrhagic fever. There were associations between dengue hemorrhagic fever with younger ages and a longer time before receiving care. Conclusions There was a greater involvement of dengue hemorrhagic fever in young people. Delay in care, poor urban quality and high endemicity were identified as possible risk factors for dengue severity.

The synthesis of fine chemicals intermediates using Friedel-Crafts acylation is one of the most important methods in chemical technology. In this work, the acylation of 2-methoxynaphthalene with acetic anhydride using a silica-supported dodecatungstophosphoric acid catalyst (HPW/SiO2) and acetonitrila as solvent was studied, showing that this reaction is a feasible alternative to produce intermediaries to replace the current methods of production. The reactions using acetonitrile solvent showed yields greater than or equal to the reactions using traditional solvents such as nitrobenzene and dichloroethane. Finally, the modified Eley-Rideal mechanism was proposed to elucidate the experimental data obtained.
