Among numerous studies about the selective collection of solid waste and cooperatives of recyclable materials, this research aims to contribute with the study of these problems from the geographic space. As the world population increases, the issue of solid waste becomes increasingly worrying, due to new consumption patterns that create larger amounts of waste, especially in the urban centers. The recycling appears to be the best solution for this problem since most materials that are currently sent to landfills would become raw material for new products. The Triage Centers performs an important role in this process because they are responsible for sorting, packing and selling the materials arising from the selective collect, so it is necessary to analyze the places where these steps are performed. This study intend to examine the location and distribution of these enterprises in the city of São Paulo in order to provide support for the mitigation of impacts, both environmental and social, from their location, as well as provide support for the expansion of selective collection program in the city. The choice for studying this area was due to the curiosity of investigating the inefficiency of the recycling program in the city of São Paulo, which currently recycles about 1% of all household solid waste collected. Therefore, from a historical survey of the city's recycling programs, technical visits, interviews with responsible agencies and also analysis of the Triage Center's frameworks based on the guidelines from the municipal legislation, it will be evaluated the problems faced by the program for its expansion

This research aimed to analyze the spatial area for the design of the Heat Island of Subprefecture Sé, in São Paulo-SP, with the support of geotecnology and based on the study of environmental perception. We used remote sensing products such as maps ofland use and soil temperature and apparent surface to evaluate the thermal conditions considered critical points in the central area of the municipality. The methodology used was qualitative analysis, based on interviews with the people, allowing rescue geoecology the conditioning aspects of the city, with an emphasis on environmental perception. This study aimed toanalyze the perception of the variation of the thermal field in São Paulo. The results indicated that (95%) of respondents feel that the temperature of the central area has increased each year, and the district that stood out was the Sé, due to intense use and occupation of land and contribute one of the largest shopping centers. Districts with points given for having better thermal comfort were Santa Cecília, the República and Bela Vista, due to their larger amount of green areas by fiscal court, which act as local refrigerators. It was found that the respondents have the perception and awareness of their spa directly related to the quality of life. Through analysis of several variables involved, proposals and strategies may support public policies and urban planning

No Córrego do Sapateiro, situado no Parque Municipal do Ibirapuera, na cidade de São Paulo, SP, Brasil, amostras de água (50 mL) na profundidade de 10 centímetros foram coletadas em locais antes (local 1) e depois (local 2) da estação de tratamento de flotação, durante os meses da estação chuvosa e quente (janeiro, fevereiro e março) e da estação seca e fria (junho, julho e agosto) de 2008. Além disso, a temperatura, oxigênio dissolvido, condutividade e pH da água foram medidos com um equipamento Horiba U10. Coliformes totais e fecais foram analisados com o kit Aquatest®. A partir de cada amostra de água, alíquotas de 1 mL foram inoculadas em meio batata-dextrose-ágar, totalizando 10 placas de Petri para cada local de coleta. Após incubação por 10 dias a 22 ºC, as colônias fúngicas foram quantificadas, purificadas e identificadas. Os parâmetros abióticos da água não foram limitantes para a presença de geofungos, sendo influenciados pelo tratamento de flotação. Nos dois locais o número de coliformes totais e fecais foi predominantemente superior a 8 NMP dL-1 durante o período estudado. Vinte e sete táxons de fungos foram obtidos, distribuídos em 136 ocorrências. de acordo com o índice de similaridade de Sörensen, a micota dos dois locais coletados foram consideravelmente diferentes, apesar da semelhança entre o número de táxons e ocorrências. Os resultados indicam que o tratamento da água do Córrego do Sapateiro pelo sistema de flotação possivelmente causa modificações na composição taxonômica e na quantidade de UFC de fungos, ao contrário do que ocorreu com os coliformes totais e fecais, cujos resultados apresentaram-se menos conclusivos.

Objective Dogs play an important role as infection source of human cryptosporidiosis. The objective of the study was to determine the prevalence of Cryptosporidium sp. in dogs as well as to compare two techniques of fecal analysis.Methods Four-hundred and fifty canine fecal samples from the city of São Paulo were analyzed between 2003 and 2004. Fecal samples were randomly selected from dogs housed in a university veterinary hospital (group 1, n=200) and private kennels (group 2, n=250). The detection of Cryptosporidium was performed using modified Ziehl-Neelsen staining and Polymerase Chain Reaction (PCR) technique. Statistical analysis was performed using the two-tailed test of significance at 5% confidence interval (z critical=+/- 1.645).Results Only Cryptosporidium parvum oocysts were found the prevalences found by light microscopy examination and PCR techniques were 8.8% and 9.5%, respectively. Young animals showed a lower frequency (5.5%) compared to adults (10.1%). There was no statistically significant difference in Cryptosporidium prevalence between males and females.Conclusions the prevalence of C. parvum in the canine population studied was similar to that one found in the literature and affects equally males and females. The use of PCR allowed the detection of more positive cases than light microscopy.
