Cerca de um tero do total de doenas em adultos esto associadas a condies ou comportamentos que comearam na juventude. No Brasil, a porcentagem de Inatividade Fsica (IF) nos adolescentes varia entre 29% a 94%, que um dado alarmante, pois esses adolescentes provavelmente sero adultos inativos fisicamente e com um risco maior de adquirirem uma doena de agravo no transmissvel. Desse modo, o objetivo do estudo foi verificar a prevalncia e os fatores associados IF em escolares do Ensino Mdio do municpio de Rio Claro- SP. Estudo do tipo transversal, de base populacional, realizado no primeiro semestre letivo de 2009 contou com a participao de 467 alunos (213 homens e 254 mulheres) das escolas particulares e estaduais do Ensino Mdio do municpio de Rio Claro-SP. Para avaliar o de nvel de Atividade Fsica (AF) dos adolescentes foi utilizado o Physical Activity Questionnarie-Children (PAQ-C). Foi aferido a circunferncia de abdmen e calculado o ndice de Massa Corprea (IMC). Os pais responderam um questionrio para avaliar o nvel de AF atravs do International Physical Activity Questionnarie (IPAQ) e o nvel socioeconmico. Para verificar a associao entre as variveis (sexo, nvel socioeconmico, IMC e circunferncia de abdmen) com o nvel de AF dos adolescentes foi realizado a Regresso Logstica e para verificar a associao entre o nvel de AF dos adolescentes e dos pais foi realizado o Teste Qui-Quadrado. A prevalncia de IF dos adolescentes foi de aproximadamente 83% e, dentre as variveis analisadas, apenas sexo mostrou-se significante (p=0,00), sendo o sexo feminino com maior chance de IF.

Laboratory of Chemical Waste Management programs are being implemented in various universities of the country and the world, in recognition of the urgent need to change the reality of disregard for the environment, together with objective responsibility of the generator, and especially the awareness of sustainability. Analysis and research laboratories involve a range of waste in developing their studies with intrinsic characteristics related to their form of generation. The amount of waste generated in this segment is negligible compared to industrial activities, but the environmental issue is that these residues do not have a standard technique for treatment due to the potential variation of its composition. This research project, aiming their suitability and continuous improvement, aims to diagnose and analyze the current situation of the management and disposal of chemical waste generated by the laboratories IGCE UNESP, Campus Rio Claro / SP. Universities, through their research, teaching and extension, end up generating potentially hazardous chemicals that may contaminate the environment when they are disposed of improperly, with no concern for the environment and / or public health. Aiming to assist in improvements with respect to this issue, the purpose of this study is to understand the management and disposal of chemical waste from the IGCE, laboratories UNESP - Rio Claro / SP, in order to discuss the situation of such waste, and present proposals to reduce generation of the same and minimizing the environmental impact, thereby increasing the local hygiene through proper disposal. The research instrument used interviews, questionnaires, review of recent literature and observations were made in order to develop proposals for the management and disposal of waste. These proposals based on prevention and corrective control, where the preventive approach aims at lifting techniques and actions to reduce the generating sources and...

The Urbanization is a notable process in our society, being part of it since around 3500 BC in Mesopotamia, currently Iraq area. Since the Industrial Revolution, cities had a significant increase in their growth and began to concentrate increasingly labor and capital. Brazil, despite having had a late industrialization, also had a high population growth in cities, especially in the XVIII century, which were not provided with any kind of planning that targets the ordering and implementation of the urban essential apparatus. Therefore, Brazilian cities started to exhibit countless structural and environmental problems. Associated with inadequate infrastructure, the modifications in the urban atmosphere, like increased heat, air pollution and increased rainfall and storm frequency, cause different types of impacts in cities. Among the most worrisome are those from the intense rain, which cause human and material damage. The city of Rio Claro (SP) can be considered an example of this reality. Thereby, the objective of this study was to analyze the impacts on the population originated from rainfall in the urban area during the period 2005-2010, by the mapping of events and analysis of the active atmospheric systems. The information of the events were collected in the Fire Department and the Press and the synoptic maps were obtained in the library of INPE, in Cachoeira Paulista (SP) and in the site of the Navy of Brazil. The data showed that among 247 occurrences, during the six years, 233 occurred in the spring-summer period. Moreover, after finalizing the maps, it was found the locations considered critical regarding the frequency of occurrences, as: Visconde do Rio Claro Avenue and central area of the city, both with a total of 23 occurrences; Jardim Inocoop, with 20; Tancredo Neves Avenue, with 12 and Vila Paulista, with 10 occurrences. Through the graphs, it was found that the most recurrent atmospheric system, during the studied period, is...

The growing demand for electricity in Brazil has stimulated the implementation of Small Hydro Power (PCH) in various regions of the country. However, the silting of reservoirs is a major problem faced by power plants and power plants. In this context, this study aimed to evaluate the data hydrosedimentological strategic points of the watershed of the Alto Rio Sucuri (MS) to identify the possible causes siltation of the reservoir PCH Costa Rica and suggest mitigation measures. Hydrosedimentological surveys were conducted during the rainy season (February / March 2012) and drought (August 2012), and obtained data flow, discharge liquid, suspended solids and bottom and organic matter content. Based on these results it was determined that the points 2, 4, 7 and 9 are the largest contributors to sedimentation, and point 4 got most liquid discharge (38,20 m3s-1), point 7 largest discharge of solid suspension (906,3 mg L-1), points 2 and 4 major discharges solid totals (231,59 t dia-1 and 238,185 t dia-1 respectively) and point 9 higher organic matter content (22,18%) . Found greater fraction of fine sand and very fine suspended solids and solid medium sand in the background. As mitigation measures for the process of silting of the reservoir PCH Costa Rica (MS) highlights the orientation of landowners in adopting conservation measures and planting of leguminous species native to the region in symbiosis with nitrogen-fixing bacteria

To verify the levels of concentration of some heavy metals in fishes from Sorocaba river (So Paulo, Brazil) and evaluate if this contamination offers health risks to the fishermen, 63 samples of fishes collected from four points along the river were studied for cadmium, lead, chromium, nickel and mercury, with emphasis in this last, since it is the most toxic and most probable as a fish contaminant. Analyzing muscle samples by cold vapor atomic absorption spectrometry it was shown that the fishes are not contaminated. None of the five metals studied were present in prohibitive level and the fishes could be judged secure for human consume. It was also analyzed data from four years of cadmium, lead, chromium, nickel and mercury monitoring made by CETESB, from 1997 to 2000, in water from the main rivers of the State of So Paulo. The study pointed out that the majority of the monitored rivers still present contamination by those metals in a level that requires an improvement of the pollution control actions.

As bebidas lcteas fermentadas so produtos formulados contendo iogurte, soro de leite, polpa de frutas, alm de outras matrias-primas e aditivos permitidos. O produto final deve apresentar os micro-organismos de forma vivel e abundante. Sua popularidade vem aumentando significativamente, principalmente devido aos seus benefcios nutricionais, ao menor custo do produto para o fabricante, reduo do preo final para o consumidor e por apresentar baixa viscosidade, sendo consumida como bebida suave e refrescante. Apesar do processo de fabricao ser considerado simples, utilizando-se principalmente os equipamentos disponveis nas indstrias lcteas, estes produtos podem estar sujeitos contaminao microbiana, quando no atendidas as condies elementares de higiene e sanidade. Tal contaminao pode ser representada por leveduras, coliformes totais, termotolerantes e bolores. Considerando os aspectos mencionados, o objetivo deste trabalho foi avaliar a qualidade microbiolgica de bebidas lcteas fermentadas, com adio de polpas de frutas, comercializadas na regio de So Jos do Rio Preto SP, por meio das seguintes anlises microbiolgicas: contagem de bolores e leveduras, determinao do Nmero Mais Provvel (NMP) de coliformes totais, temotolerantes e pesquisa de Escherichia coli e de Salmonella spp. Foi ainda efetuada a determinao do pH eletromtrico. Aps a obteno dos resultados verificou-se que 20% das amostras analisadas no atenderam ao padro microbiolgico estabelecido na legislao vigente, para coliforme termotolerentes, evidenciando positividade na pesquisa de Escherichia coli, sendo por este motivo, considerados como produtos em condies sanitrias insatisfatrias, portanto, produtos imprprios para o consumo humano.(AU)

Located in the Pantanal of Miranda-Abobral, the Baa da Medalha is the largest pond close to the Base de Estudos do Pantanal of the Universidade Federal de Mato Grosso do Sul. The Baa da Medalha has been a study site for several didactic and scientific projects for years. Nevertheless, its fish fauna has never been inventoried. Based on data collected from the beginning of the 1990s up to 2011, we provide a list of fish species from the Baa da Medalha. A total of 97 species were recorded, corresponding to about 40% of the species stated for the Pantanal. Characiformes and Siluriformes were the most species-rich orders, being Characidae and Cichlidae the families with the highest number of species. Regional seasonal flood dynamics and the abundance of aquatic macrophytes may be associated with this high diversity. The representative richness found in this lagoon highlights the importance of such taxonomic surveys to preserve the diversity of aquatic habitats within the Pantanal ecosystem.
