Distribuição espacial das assembleias de peixes em dois trechos do alto rio Paranapanema e lagoas marginais associadas: composição e estrutura

Ichthyofaunistic studies aims to broad the knowledge of composition, abundance and distribution of species in certain areas, and when possible, to infer patterns of distribution, as well as extrinsic factors that affect these patterns in space and time. The Paranapanema River suffers the impact of the construction of hydroelectric power plants in cascade system along its main channel, changing the characteristics of lotic to lentic and semi-lentic. These changes affect the entire biocenosis and the surroundings of the reservoir and, in particular, the fish fauna. In this context, the aim of this study was to characterize the fish assemblage in two lakes and stretches of the main channel, located near the outfall of the Paranapanema River, Jurumirim reservoir area, comparing them to their composition and structure, using ecological indices as tools. Fish were caught every three months from April 2011 to January 2013, using gill nets of various mesh openings in four stretches: Environment 1 - Calha Sete Ilhas, Environment 2 - Calha Poço da Pedra, Environment 3 - Lagoa Sete Ilhas and Environment 4 - Lagoa Poço de Pedra. After the capture, the specimens were identified and biometric analysis was performed (total and standard length weight). We captured 4,006 individuals belonging to four orders and 34 species, 31 native species and three non-native species. In abundance (n) and number of species (S), there was a predominance of Characiformes (57 %) followed by Siluriformes (31%). Overall, most of the species was constant concerning the frequency of capture. The five most representative species in abundance were Schizodon intermedius, Cyphocarax modestus, Pimelodus maculatus, Hoplosternum littorale and Serrasalmus maculatus, contributing with 60% of total individuals captured. Regarding the stretches, these species present diversity (H'), evenness (E), dominance (D) and richness (d) of similar species, since the abundance was higher in ...

A gênese e a distribuição socioespacial das chuvas no município de Ubatuba-SP

This monograph aims to contribute to the understanding and analysis of extreme events and its correlation with anthropogenic actions, in order to understand the levels of human interference in the environment and to identify potential social and environmental damage that such events may result in Ubatuba, located on the northern coast of São Paulo state. Therefore, two strategies were established, on one hand, episodic analysis of extreme weather events, and on the other, the analysis of the impact of atmospheric phenomena in everyday society. In this case we gave greater emphasis to analysis years that had higher total rainfall. In this sense, the research was based on the standard deviation technique and percentages, which supported to characterize the exceptional rainy years, in addition, use of rhythm analysis technique that has helped to identify the active atmospheric systems. From a qualitative point of view, field works were carried out in order to make use of news by the local press and civil defense for years considered extreme (positive standard deviation). From this, it was analyzed how the extreme episodes of rainfall trigger repercussions in geographic space. Also the spatial distribution of rainfall were carried out by means of quantitative analysis of six rain gauges. It was found that the highest occurrences of impacts, are located in the central areas of the city, as well as the highest rainfall totals. In fact, Ubatuba/SP suffers from very high rainfall totals and has a singularity on the climate...

Distribuição Geográfica dos Escorpiões no município de Presidente Prudente - SP nos anos de 2012 e 2013

No Brasil os acidentes por picada de escorpião são considerados um problema para saúde pública, uma vez que este agravo pode levar ao óbito caso não haja um tratamento adequado. Assim, no município de Presidente Prudente/SP o órgão responsável pelo combate aos escorpiões é o Centro de Controle de Zoonoses (CCZ), que tem por finalidade notificar a aparição de escorpiões no município, promovendo portanto, as devidas informações à população com finalidade de evitar acidentes. Desse modo, com o uso dos Sistemas de Informações Geográficas (SIGs) aplicados à técnicas de estatística espacial, foi possível elaborar mapas de distribuição das notificações de escorpiões referente aos anos de 2012 e 2013, por meio dos métodos da geocodificação de endereços; estimador de intensidade de Kernel; índice de Moran função (LISA); quantidade de notificações por setor censitário e interpolação por vizinho mais próximo. Como resultado desta análise, o trabalho fornece informações ao CCZ sobre a distribuição de tal fenômeno para que fosse possível um controle direcionado os locais mais infestados, economizando tempo e recursos financeiros, visando o bem estar da população

Soluções numéricas de Equações Diferenciais Fracionária e Ordinária para o cálculo da distribuição da concentração em um sistema de compartimento

The purpose of this work was the study of numerical methods for differential equations of fractional order and ordinary. These methods were applied to the problem of calculating the distribution of the concentration of a given substance over time in a given physical system. The two compartment model was used for representation of this system. Comparison between numerical solutions obtained were performed and, in particular, also compared with the analytical solution of this problem. Finally, estimates for the error between the solutions were calculated

A distribuição espacial da indústria do vestuário no Brasil

This paper aims to analyse the spatial distribution of the Brazilian clothing industry in 1997 and 2006. In order to achieve this objective, this study used an exploratory spatial data analysis - ESDA. It was made a univariate analysis of the number of the existing clothing industries among Brazilian states. The null hypotheses of the spatial dependence absence was rejected and the construction of cluster maps showed two patterns: a high industrial concentration and a low one. On the other hand, a bivariate analysis was also conducted to permit a study between the number of clothing industries and the wage income of the neighbor regions. The result revealed spatial dependence besides similar cluster maps in both years. Therefore, two spatial patterns emerged: a high and a low industrial concentration. The final conclusion is that agglomeration economies are the main responsible for the results found in both analyses.

Uma proposta de integração entre a abordagem kaleckiana da distribuição setorial funcional da renda e a teoria schumpeteriana do processo de concorrência

This paper uses a theoretical schumpeterian and kaleckian to analyze the dynamic effects of innovation on competitiveness and sectoral functional income distribution. By affecting the mark-up and market power successful innovations allow the expansion of the asymmetries between firms, intensifying competition and promoting mismatches in sectoral income distribution between wages and profits.
