Aplicação do método AHP para hierarquização de condicionantes de corrida de massa

Among the flow, the flows have the highest destructive potential, may cause disasters with a very high number of victims, as recorded in the events Caraguatatuba (SP) and the Serra das Araras (RJ) in 1967; Valeu do Rio Figueira, in Timbé do Sul (SC) between 1995 and 1996; Vale do Itajaí in Santa Catarina, in 2008, Teresópolis, Petrópolis and Nova Friburgo (RJ), in December 2010 and January 2011. This project aimed to prioritize the main determinants of inducing processes of debris flows by applying the method of decision making AHP (Analytical Hierarch Process). Therefore, the following stages of work were defined: research of the major factors of debris flows, questionnaire design method for application of AHP expert on the subject, analysis of the results obtained from calculating the ratio of consistency and preparation of proposal for hierarchical of conditions for debris flows. From the surveys it was possible to establish a relationship of conditions according to the scale of work, defining three levels: regional (1:250,000 to 1:100,000), Semi-Detail (1:50,000 to 1:25,000) and Detail (1: 10,000 or higher). The factors found were: concentration time, the flood wave, rain, landslide susceptibility (slope), drainage and development in the deposition. The project analyzed the results obtained from the questionnaires, which allowed the ranking of the constraints, contributing to weight constraints in studies of multicriteria mapping of susceptibility to the occurrence of debris flows. The study showed that the most of the analyzed datas were inconsistent because of the different opinion of the judges

Desenvolvimento de metodologias analíticas para determinação de selênio, cobre e manganês por GFAAS em amostras de vegetais de cultura orgânica e convencional utilizando extração por ultra-som

No presente trabalho é proposto um método para determinação de cobre, manganês e selênio em amostras de vegetais de cultura orgânica e convencional utilizando ultra-som no processo de extração dos analitos e posterior quantificação por espectrometria de absorção atômica em forno de grafite (GFAAS). Utilizando como solução extratora HCl 0,10 mol L-1, as condições ótimas de extração estabelecidas foram: massa de amostra de 100 mg; granulometria da amostra < 60 m; tempo de sonificação de cinco ciclos de 40 s e potência de sonificação de 136 W. As determinações dos analitos por GFAAS foram feitas utilizando-se temperaturas de secagem de 90-250 oC, temperatura de pirólise de 1300 oC, temperatura de atomização de 2300 oC e temperatura de limpeza de 2800 oC. Foi utilizado como modificador químico nitrato de paládio co-injetado junto com as amostras e tungstênio como modificador permanente. A exatidão e precisão do método de extração proposto foram avaliadas utilizando-se padrão certificado Corn Bran, RM 8433 – National Institute of Standards and Technology. Os resultados obtidos pelo método de extração por ultra-som mostraram-se equivalentes aos obtidos pelo método utilizando-se mineralização ácida das amostras em forno de microondas. No entanto, a metodologia proposta diminui consideravelmente o tempo de análise, o que favorece a velocidade analítica. Além disso, a quantidade de resíduos gerados para o ambiente também é bastante minimizada

Comportamento da temperatura da massa de resíduos aterrados em um aterro sanitário

In this paper we investigate the temperature variation of the mass of waste along the depth in a household waste landfill of Rio Claro - SP, São Paulo, having a climate characterized as Tropical Altitude. In this research, there were two holes in two distinct points of the landfill, with different depths and characteristics in order to fix several thermal sensors - RTDs - to record the temperature at predetermined depths. Overall, the results show the influence of temperature at depths of up to 3.0 meters (from the surface) and that it varies in a manner to stabilize at depths above 5.0 meters. The highest temperature obtained was approximately 37.5 ° C for a time of waste disposal of 7 to 10 years. The results showed the presence of organic matter (substrate) which resulted in elevated temperature resulting from biological activity

A literatura de massa na perspectiva dialógica

Building on some core concepts of dialogic discourse analysis, this article aims to discuss, through an examination of the bestseller lists in Brazil during the years 2000 to 2010, the central features of contemporary mass literature. By the evidence of the prevalence of self-help books, we examine how the phenomenon is consisting. The conclusion that we get is that self-help can be seen both as a discourse genre and as style.

O enunciatário da revista VEJA: contribuição para discussões sobre indústria cultural e cultura de massa

This work intends to “test” two theories about mass cultural products – one that understands them as syncretic and plural and another that sees them as homogenizators and aimed to a mixed audience. We chose Veja magazine as the object of this study and tried to understand how its internal sessions bring in their readers, with the goal of verifying whether readers shared characteristics. In the affirmative case, Veja would be directed to a specific reader; otherwise, it would be a syncretic cultural product. This answer should give us basis to reflect upon the opposition between both ways of thinking about mass culture and help us take a stand on this discussion. Obviously, we do not intend to give a definitive answer to the opposition between these two tendencies. The limits of this work are given by the investigated object itself: we intend to verify empirically how Veja, as a cultural product, solves the contradiction that the co-existence of these two opposite theories point about mass society.

Acúmulo de massa seca na soja em resposta a aplicação foliar com silício sob condições de déficit hídrico

The foliar fertilization with silicon has promoted several actions beneficial to plants, among them is greater drought tolerance, however, for the soybean, there is little information on these benefits in this condition. Thus, the aim of this study was to evaluate the effect of silicon on leaf, the dry matter accumulation of soybean in their reproductive stages, where the crop water stress suffered during the same. The experiment was carried out at the Plant Science Unit Aquidauana University - State University of Mato Grosso do Sul. The statistical design was a randomized block split plot with four replications. The plots were represented by cultivar 5DR615, the subplots consisted of the application (with or without) silicon, whose source was used KSi. Was measured the height and identified the development stage of all plants, separating them into stem + branches, leaves + petioles, pods capsules and seed. Foliar applications of silicon increased dry matter accumulation during the reproductive stage of soybean, where the highest values occurred in the R6 stage. Under conditions of water deficit, foliar application of silicon on soybean provided normal plant development, generating greater dry mass of stem + branches, leaves + petioles, pods capsules and seeds throughout their reproductive phase, with the highest values obtained at R6 stage (35 days after R2).
