The species Pimelodus maculatus is one of the most abundant fish in many artificial reservoirs. Shows feeding plasticity and exploits all trophic levels in aquatic ecosystems. This study aimed to analyze and compare aspects of the diet of P. maculatus in two important tributaries (Taquari and Veados rivers) in the upper Paranapanema River system, and also investigate possible differences in the condition factor using its feeding habit as reference. Samplings were carried out every three months during 2011 and 2012 in two tributaries of Jurumirim's dam. After biometric analysis, fish were dissected to remove the stomachs that were fixed in formaldehyde 10% and conserved in alcohol 70%. The stomach content was analyzed under stereomicroscope and the food items were identified until the least possible taxonomic level. The diet was characterized based on the Alimentary Index (IAi). Feeding strategy and aspects of species autoecology were evaluated by the relation between abundance of prey-specific (Pi) and occurrence frequency (Fo) of the prey, and also was calculated the niche width of Levin (B). The condition factor was also established and values obtained in samples of both rivers were compared, correlating them with diet of the species

This article has, as its main subject of reflection, a brazilian experience of intermunicipal cooperation named the "Consórcio Intermunicipal pela Conservação da Natureza na Bacia do Rio Jacaré Pepira" better known as "Consórcio do Rio Jacaré", located in São Paulo State, Brazil. Having its origin in 1985, the consortium is considered the first inter-municipal experience of cooperation witch tried to associate regional development with environmental issues. The research, qualitative in the method, designed as single case study and supported by data collected through desk research, systematized information on the projects and activities of the Consortium, pointing among the members those which effectively beneficed from the supposed cooperation, along with the difficulties faced and the context which led the consortium to the state of stagnation in which plunged after 1999. The results showed that, despite its historical and regional importance, the consortium could not be seen as a management model, being weakened by the political and institutional environment, the local realities, the absence of maturity of partners for joint cooperation, in addition to the lack of clarity on the regional dimension of the projects.

O cádmio (Cd) é um metal tóxico considerado não essencial nos organismos. As principais vias de exposição e contaminação pelo metal vem de atividades antrópicas. Há evidências suficientes de que o Cd e seus compostos são carcinogênicos, tendo como principais órgãos afetados: rins, ossos, pulmões e próstata. No citosol o Cd pode estar na forma livre (genericamente, como complexos inorgânicos lábeis) ou ligado com metalotioneinas (genericamente, ligado a proteínas). A relação do Cd (livre ou lábil) com patogenicidades faz com que seja de grande importância a elaboração de métodos para especiação do metal. Este projeto teve como objetivo propor um método para determinação seletiva do Cd lábil em baixas concentrações (μg L-1) utilizando um substrato biológico como material sorvente (S. cerevisiae). A utilização da S. cerevisiae tem sido recomendada para pré-concentração e especiação de metais em água e materiais biológicos. No entanto, estes métodos não proporcionam limites de detecção (LD) suficientes para determinação seletiva de Cd lábil em algumas situações, particularmente quando se procura estabelecer uma relação desta fração do metal com algumas patogenicidades. O método desenvolvido consiste, basicamente, em amostrar o Cd lábil no citosol pela levedura. Depois de digestão ácida em sistema pressurizado (micro-ondas) e/ou da eluição, a espécie retida pela levedura foi determinada por ICP-MS. O uso da ICP-MS permitiu atingir LD suficientes para detecção de Cd, sendo para retenção 0,004 μg L-1 e para a eluição 0,003 μg L-1

Regular physical activity can prevent and treat various diseases and non-communicable diseases such as diabetes, hypertension, obesity and cardiovascular disease. However, the prevalence of physical inactivity among adolescents in Rio Claro is 83%. Thus, it is necessary to encourage physical atividade through the community, especially parents and schools. The objective was to investigate the influence of two types of gym class in functional abilities in high school students in the city of Rio Claro-SP. Methodology: The study included 20 students from high school, 8 boys and 12 girls. The study took place in two high school halls of a public school in the city of Rio Claro. With the collaboration and participation in only 10 students in each room search reviews of all students occurred in mid-July in the year 2012 with the completion of the battery of tests and application of PAQ-C questionnaire at the beginning of classes of and after three months. All students were subjected to the test battery Eurofit. To compare the values of physical fitness for each type of class was held factorial ANOVA for repeated measures using SPSS and the level of physical activity was performed the Wilcoxon test. To compare the delta values (post-test-time time pre test every physical fitness) we performed the t test for all analyzes was adopted p <0.05 Classes G1 followed the schedule proposed by the state 's Notebook, where he worked subjects as body and beauty and its relationship with the media today, prevailing more conceptual classes than procedural . Unlike what has been developed with the G2 who had classes were focused on physical fitness and physical conditioning to increase the level of physical activity inside and outside the school environment . Result :The results from the data collected in this study indicate that physical fitness is not worked continuously or expressive within the Physical Education classes of high school to the population...

This scientific research aimed at to analyse the susceptibility to debris flow of the watershed of Ribeirão do Roque (SP), focusing on the upstream areas of OSBRA pipeline. This is because, mass flow can cause damage to pipes, mainly due to conditioning hydro erosion of the land in the drainage crossings, including the undermining the banks of streams. Firstly, It was conducted a literature review, aiming to identify and understand the principal characteristics and conditions of debris flow. Secondly, the physical and anthropic factors and their respective weights of influence were selected and used to determine the mass flow susceptibility. It was selected the following physical factors: type and thickness of rocks, soil and unconsolidated materials; textural density; amplitude relief; relief slope; shaped valley; and shape of slopes. Such factors are present in the physiographic subdivision map of the study area. In addition, the anthropic attributes correspond to the classes contained in the land use map. Therefore, the physical and anthropic factors were integrated through the multi-criteria analysis in a GIS environment, generating a total susceptibility map of debris flow on the scale 1:50,000. The results showed that a significative part of the study area was classified as average susceptibility. However, it was identified areas with high susceptibility in the region in which the pipe cross the Ribeirão do Roque. Moreover, at which point the river presents a closed valley and a meander shape, without a fluvial plain that would be useful to attenuate the development of the process. Consequently, if a mass flow begins in any of these most susceptible regions located upstream of the pipe, the chances that the process develops by the river and causes the excavations of his bed are quite large. However, the pipelines cross these critical areas directly on the rock (diabase), which provides additional protection against possible ...

The aim of this paper was to evaluate the effect of retention and detention reservoirs along with the regulation in channel flow upgrade on flood for an urban watershed located at Rio Claro, SP. For this purpose, modeling and simulation techniques were applied for runoff determination and its propagation in channel. The Soil Conservation Service – SCS hydrologic model as well as Pulz and non-linear Muskingum-Cunge model were used. The software IPHS1 was applied on simulations. The results pointed out that the combination of retention increasing and detention reservoir implementation (120,000 m3, corresponding to 1.5% of the watershed area) with the streamflow upgrade (n decreasing from 0,04 to 0,02) can minimize the flood on the investigated Servidão watershed. Further, after the proposed intervention, the flood was eliminated for the investigated times of recurrence: 5, 20, 50 and 100 years. The prognostic indicated that the available area occupation had a minor effect on flow increasing due to the observed high urbanization.
