The work is guided by the detailing of the Itajaí river basin, SC, rainfall dynamics at the annual, seasonal and monthly levels, allowing us to identify different responses that each location gives to the regional atmospheric circulation, particularly the rainfall. In this sense, we are aiming at approaching the concept of rhythm, which must be obtained at the daily level. The analysis at different climate scales was possible through isohyetal maps, trend lines, and Schroeder pluviographs. Moreover, we established the flow rate of the air masses by means of the Venn diagram. This data made it possible to assess the behavior of rains on that site and the reason why it is the stage of major flooding, as occurred in November 2008. The relatively mountainous topography combined with the frequent invasions of the Atlantic Polar Front, which often stop over the region, generate events of that magnitude, with high volumes accumulated in short periods of time. Such extreme events reinforce the idea of the search for the succession of types of weather to the detriment of averages that tend to abstract the reality

Silicosis, a common type of pneumoconiosis, is an occupational lung disease caused by inhalation of silica dust often with mining activity and thus reaches the miners. The fine and ultrafine silica particles deposited in the alveolar epithelium may lead to the development of progressive massive fibrosis. An increased reactive oxygen species (ROS) production has been proposed to explain the mechanism for induction of pulmonary fibrosis in silicosis. In this situation, alveolar macrophages are activated to phagocytes silica particles deposited in the alveoli. The activated macrophages secrete large amounts of ROS that in turn induce synthesis of fibrotic factors. In addition, the activity of antioxidant enzymes is impaired, which results in increased lipid peroxidation, as well as generating a local inflammatory process. Diffuse pulmonary fibrosis progresses with interstitial collagen deposition. Interstitial collagen overlies small pulmonary arteries and arterioles and thus it is associated with pulmonary hypertension in pulmonary fibrotic diseases. In addition, cytokines and silica particles passing through the respiratory membrane can reach the bloodstream. In this context, the increase in the generation of ROS in the circulation may lead to a reduction in the bioavailability of nitric oxide, an important endothelium-derived relaxing factor. A deficiency in the nitric oxide bioavailability can result in vascular endothelial dysfunction. Moreover, pro-inflammatory cytokines could contribute to the impairment of endothelial function. In the airways, pro-inflammatory cytokines can reduce the smooth muscle responsiveness to β- adrenergic agonists as isoproterenol. Thus, the aim of this study was to evaluate the effect of silica dust instillation in the function of the pulmonary artery, aorta and trachea of rats with acute silicosis. For this purpose, male Wistar rats were anesthetized... (Complete abstract click electronic access below)

This study is about a heating line that uses thermal oil. It is located in a facility that produces interlayers used in cars windshields. A plastic resin is melted and is sent to a matrix called DIE where the interlayers are produced. The DIE needs to receive heat from the circulation of thermal oil in four different regions of its interior, to ensure the correct thickness of the interlayer. The thermal energy is provided by electric heaters and the flow of thermal oil is impelled by four mechanically sealed centrifugal pumps (one per region). The key point of this study is the fact that these four pumps of the system have reported successive failures in the mechanical seals. Apparently, a poorly designed project has burdened the system intermittently. The pumps operation condition is located in a region of low efficiency, according to the characteristic curves. This fact is the source of the noticeable reduced time between failures. Changes in the configuration of the facility and in the number of pumps will be proposed, aiming to achieve higher operational efficiency. The proposals will be mathematically analyzed according to the Hydraulic Institute criteria. At the same time, we will also keep focus on an in-depth study of a heating system structure, starting with a detailed approach for each component and discussion about its real need and economic viability. At the end of this paper it is shown that the gain in efficiency achieved with the new proposed configuration reflects not only in the reduction of maintenance costs, but also a potential improvement in energy efficiency. It is shown that these two aspects are closely related and together form the basis for the design of a reliable and efficient pumping system

This research is aimed at discussing the ways in which social agents influence global warming, analyzing the discourse of social actors involved in the debate on climate change, since there is a wide divergence in the scientific community about how man is able to modify the climate on a global scale. In fact the debate that permeates the issues beyond the limits of science and enter into a political-economic framework that takes extraordinary proportions. This emphasis can be very unscientific in the fundamental design concepts, or even creating a trivialization of the media. The main way to convey these concepts is to disclose them in the media, but the media has enormous power to transform the concepts and often manipulate the news by creating a common sense goes against the interests of the scientific community. Thus was conducted extensive research in major newspapers and magazines that move in the country. We surveyed the first two papers which were: “Folha de S. Paulo” and “O Estado de S. Paulo”, during the period from January 2000 to December 2008, totaling 3285 units for the newspaper Folha and 2555 for the newspaper Estadão. Subsequently a survey was made of data published in two journals that move at the national level, and these are the magazines VEJA and ÉPOCA for the same period. By performing these steps, it was concluded that several factors involving the media and climate change, such as topic relevance, types of approaches, perspectives of analysis, the staff development, supplies, among other factors of utmost importance for building news. As a result we can say that the media in fulfilling its role of mediator scientific, disclosing only a vision that permeates the scientific debate. The newspaper media, especially newspapers, has an informative and instantaneous. Often this preoccupation...(Complete abstract, click electronic access below)

The development in recent years of different media formats has boosted the consumption of narratives, generating a ‘narrative hunger’. Audiences have increasingly looked forward to absorb new and old narratives, and ‘adaptation’ has become a key operational concept to describe processes involved in the transformation of texts. Thus, our discussion will be centered around a few theoretical propositions on adaptation and appropriation in various textual architectures. Although relevant to the debate, literary canonical texts will not be the primary focus. Non-canonical texts will be used to re-visit concepts such as narrativization, intertextuality and transmediality and also to elaborate some ideas on interactivity and multimedia crossover.

The contemporary Brazilian poetic production is marked by a strong diversity in the forms of expression and the thematic contents that it makes circulate; it is found either turned to the critical reading of the Brazilian poetry‟s most traditional repertoire, or more concerned about the research of new expressive models afforded by language. Such constitutive diversity, which operates on the intermediate gradients between these two tendencies, finds itself underlined by the little orthodox practice of the production divulgation and circulation, that appropriated the internet and the poetic performances to compensate the low paper-based edition. What we have is a type of poetic dialectology which identifies the poetry readers group. Verifying the most regular procedures in the construction of the dialectology, through the work of Eucanaã Ferraz and João Cabral, is the objective of this paper.

The researches on sexuality, especially from Foucault’s critical analysis, have been denouncing that the sexual repression also happens through the patterns that suggest a fixed happiness model to be followed, not considering the autonomous development of the subject. The aim of this descriptive-qualitative study was to make a critical analysis of the content of the book Sex and The City, which presents narratives about sexual and love relationships in New York. This analysis evidenciated the reproduction of outdated sexual concepts presented on the following thematic categories: (1) Comprehension of the single woman as lonely and unhappy; (2) Comprehension of the single woman as independent and consumerist; (3) Comprehension that the single woman needs a heterosexual relationship related to the happy romantic ideal; (4) Comprehension of the love relationships as commodities: people as objects of use and exchange. The sexual and love patterns presented by the book demonstrate the repression reproduced uncritically by the mass culture. The Psychology has been an important area of the science to denounce the control of the sexuality from these perverse and ideological patterns.

Na presente publicação apresenta-se análises de um conjunto de manuais escolares que circularam na Escola Normal brasileira e portuguesa entre meados do século XIX e meados do século XX a partir de diferentes olhares, reeditando em outra chave o processo original de circulação de ideias entre Brasil e Portugal no qual esses materiais se inserem. Orientados por outros estudos que tratam do mesmo tema, os autores realizaram recolha nos dois países a fim de comprovar a circulação do corpus empírico que, ao final, foi definido como fonte. Assim, chegou-se ao seguinte conjunto de manuais didáticos: Elementos de Pedagogia de Affreixo & Freire (1870); Curso Prático de Pedagogia Destinado aos Alunos-Mestres das Escolas Normaes Primarias e aos Instituidores em Exercício de Daligault (1874); Lições de Pedagogia Geral e de História da Educação de Pimentel Filho (1875); Lições de Pedologia e Pedagogia Experimental de Faria de Vasconcelos (1910); Lições de Metodologia, de Fonseca Lage (1920); A arte da leitura, de Mário Gonçalves Viana (1949) e Lições de Pedagogia, de Aquiles Archêro Junior (1955). Os pesquisadores utilizam diferentes lentes para tecer suas análises e, cada um segundo sua especialidade de pesquisa, aprofunda aspectos que, juntos, compõem um painel interpretativo sobre o processo de escolarização e seus espaços, a normatização do trabalho docente, os princípios que nortearam a seleção cultural para a escola primária, a constituição de modos e métodos de ensino para realizar os objetivos educacionais e a especificidade que assumem os materiais e o ensino da leitura e da escrita nessa instituição. Todas as análises reiteram a importância dos impressos na consolidação da escola primária portuguesa e brasileira, notadamente no que se refere às prescrições feitas nos manuais escolares que, em trânsito, configuram-se como palavras viajeiras.
