A preocupação ambiental em relação aos resíduos de equipamentos elétricos e eletrônicos (REEE) vem crescendo muito nos últimos anos devido à presença de substâncias perigosas que podem causar danos ao ambiente e à saúde. O trabalho teve por objetivo investigar o destino de REEE gerados no Campus Quadrilátero da Saúde/Direito (CQS/D) da Universidade de São Paulo (Faculdade de Medicina, Faculdade de Saúde Pública, Escola de Enfermagem, Instituto de Medicina Tropical e Faculdade de Direito), a partir do momento em que os mesmos deixam as dependências da Instituição e identificar potenciais riscos à saúde e ao ambiente, decorrentes das atuais ações de gerenciamento dos REEE nas unidades estudadas. A pesquisa desenvolveu-se em 3 etapas: a) pesquisa bibliográfica e documental; b) visitas às unidades que compõem o CQS/D, e identificação de cinco intituições filantrópicas como principais destinos; c) visitas aos locais identificados para investigar as atividades desenvolvidas para a recuperação de equipamentos, componentes ou materiais recicláveis, com base em um formulário desenvolvido. Adicionalmente, foram realizadas visitas a outros quatro locais de destino de REEE. Foi identificado que as etapas realizadas nas instituições são: recebimento, teste, conserto e desmontagem manual e que o destino dos REEE pode ser considerado problemático, já que os rejeitos acabam sendo descartados como resíduo comum, podendo causar danos ao ambiente e à saúde. Além disso há riscos ocupacionais, pois os trabalhadores, além de não utilizarem equipamentos de proteção individual necessários, nem sempre recebem capacitação para exercer suas funções

The genus Brachycephalus is endemic to the Atlantic rainforest and is distributed mainly in the southeastern and southern Brazil. Currently, it has 17 recognized species, most of them, associated with mountainous habitats along the Serra do Mar and Serra da Mantiqueira ridges. Here we use an ecological niche modelling approach based on climatic variables, to assess the potential niche of the mountainous species of this genus. The model generated was then projected to future scenarios considering the last IPCC report, in order to estimate the impacts of climate changes on these species distribution. Results show a decrease in the total suitable area for the mountainous Brachycephalus species, as well as tendencies already observed for other organisms, such as, pole and upward migrations. A southern area on Planalto de Paranapiacaba increases in suitability for these species. We suggest special efforts on new surveys and conservation on the northern part of their distribution, once this seems to be the region more affected by climate changes on the projected scenarios

Costões rochosos são ecossistemas que propiciam o desenvolvimento de comunidades com grande riqueza de espécies e são ambientes de muita importância para a manutenção dos ecossistemas costeiros. Tais ambientes estão extremamente sujeitos a impactos antrópicos, principalmente no que se refere às contaminações por petróleo. O município da Ilhabela concentra o maior número de costões do Estado de São Paulo, e apresenta um notável histórico desses derrames. A fim de contribuir com o monitoramento dos costões da área do Canal de São Sebastião executado pela CETESB, o presente trabalho tem como objetivo central o estudo da estrutura da comunidade do costão rochoso da Praia da Feiticeira, um dos pontos monitorados pela CETESB entre 1993 e 1996. Além da caracterização das variáveis abióticas, a metodologia, com relação as variáveis biológicas, foi dividida em três partes: estudo quantitativo das espécies dominantes da macrofauna séssil encontradas no campo, baseado na porcentagem de cobertura de Chthamalus bisinuatus (Cirripedia), Brachidontes sp. (Bivalvia) e Tetraclita stalactifera (Cirripedia), gerando gráficos sazonais e demográficos. Para aprimorar as comparações entre os dois trabalhos, foi feito o Teste de hipótese para igualdade de proporções, comparando ano a ano as coletas de inverno, que mostrou que as três espécies dominantes obtiveram mudanças de um trabalho para o outro, rejeitando assim a Ho em todas as situações; estudo qualitativo das espécies de macrofauna e macroalgas encontradas dentro da área amostrada. Este levantamento resultou em uma lista de espécies que foi adicionada ao inventário do programa de monitoramento. O índice de similaridade entre os dois trabalhos foi determinado segundo o coeficiente de Sorrensen, que mostrou uma similaridade média entre as comunidades. Estas espécie ...(Resumo completo, clicar acesso eletrônico abaixo)

The urbanization process in the Brazilian cities is directly linked to its main economic activities, and causes several impacts on the natural resources. It can be seen at the city of Ilhabela, an archipelago located at the north coast of the state of São Paulo, that still has a great area of preserved Atlantic Rainforest, and where today the tourism is the main economic activity. With this in sight, this paper aimed to make a prospect of the current situation of the city, looking at the main aspects of its economic and urban development and the environmental impacts related to them. Among the aspects studied, are the irregular occupations at preservation areas on the island: the pressure on the sea ecosystems by the fishing and the boat circulation, and at the beaches by the tourists flow. Were also observed the characteristics of the city’s urban infrastructure, such as the water supply, sewer and road networks and the waste collecting. Finally, it was analyzed the way that the government acts over the preservation of the island’s natural resources, by the Municipality and the Ilhabela State Park, so that the acting of these two agents could be compared

The intensive development in the urbanization process implied a series of economic, social, and gradually, environmental transformations, essentially, since its intensification, which took place from the Industrial Revolution in Europe and North America. In Latin American countries, including Brazil, there was such acceleration in urban sprawl, only in the middle of the twentieth century, fomented by a peculiar industrialization, coming from the scientific-technical revolution, which occurred in developing countries. In this context, and with a lack of planning and an effective organization, cities of the dependent countries face an inordinate population growth and an unprecedented industrial swelling. Brazil, following this trend, presents several issues regarding the gaps in the provision of necessary infrastructure to meet the most basic needs of its population and the intense activity and anthropogenic effects on the environment. In this sense, environmental problems, related to air and water pollution, degradation and contamination of soil, paving roads, reduction of green areas, urban heat island, among others, reaching ever deeper into the Brazilian urban areas. It is important the analysis in this final project, the weather events related to episodes of strong winds and the events and the impacts to the population of Rio Claro (SP) in the period 2005 to 2010, basing themselves in Geographical Climatology and Urban climate studies. In this scenario, we found the prevalence of occurrences linked to falling trees in the study area, connected, at the same time, to the occurrence and to the absence of episodes of extreme events, with measurements of strong winds, showing a connection between the events and external facts to episodes of winds

Nowadays, there is a need for improvements in production processes for companies to be competitive, as it is an obligation of businesses, it is necessary to know about the production processes accurately, to learn where improvements in work and thus have large impacts results. The calculation of efficiency of production lines is necessary to know as much about the progress of production and for product costing, when the measurement is not suitable, it generates negative impacts on the company. Due to the impact generated by this parameter, the graduation work carry out the study of change in a method that does not include all requirements necessary, by another method known as Overall Equipment Effectiveness, and according to studies, covering various parameters, showing become more consistent. These values are contained in the pattern production which is used to fund the product, thereby also occur financial impacts. Thus the work will study the change along with the analysis of impacts caused by the change

The construction of the São Paulo International Airport in Guarulhos recorded significant economic growth for the whole region, especially for services and jobs generated. Despite the importance of its presence in Guarulhos, we note the absence of an articulate and committed planning to urban development of the city, mainly in adjacent areas to this airport system planning. Through this stud, we analyzed primarily the major interferences and modifications afforded by its presence in guarulhense spatiality. We found that the government was, to some extent, tolerant to mounting housing in the surrounding area to the airport, from the moment that allowed the diverse urban land use in the place where it was planned to build such equipment. We further note that the airport is developed autonomously to the municipality in which the investments and related works only aim to meet the needs of the enterprise

This article discusses, in general matters, the economic and social motivations, the organization and development of the program Minha Casa Minha Vida, made in 2009, by Federal Government of Brazil. The objective of this work was to analyse the Brazilian economic and housing context, and the program relation with the Subprime international crisis, which has been started at United States in 2008, as well as analysing and discussing the logistics and the program accessibility. The MCMV program, part of the PAC – Programa de Aceleração do Crescimento – has the intention to combat the economic crisis that had been installed and also minimize the deficit housing of the country. From PAC's initial estimate, US$250 Bi, it has been spent US$129 Bi and it has already been approved more than US$125 Bi designated for the second stage of the program, whose the estimate of PAC2 is about one trillion and a half of brazilian reais. One million homes were built between 2009 and 2012, and the goal for 2014 is two million and a half of new residences. If comparing the current program with the oldest programs, progress were observed ,however, problems and inconsistences are clearly seen: in the real concernment, the truly beneficiary, and contradiction between a social and economic program to urban demands, among other situational factors. It’s also evident, the incentivation for a new residential and closed neighbourhoods, thereby adding to the fragmentation of the urban space, beyond of the exclusion socioespacial caused financing of residences in farest allotments. The capitalist production of the space it’s clearly thriving in analysis of thisfinancing package of the urban habitation, where the biggest glebas rise between central neighbourhood and the newest generated suburb, they evidence the negligence of the authorities in well managing the space, not executing the application of urban instruments of planning the social function, and...

Acoustic communication is essential in mammals and has three main functions: acquisition of information about the environment, intraspecific communication and detection of predators and prey. Studies indicate that the introduction of sounds produced by anthropogenic activities such as military exercises, use of sonar and activities related to the extraction of oil and natural gas can cause interference in cetacean communication. Recently, the discovery of pre-salt tends to increase these activities. After a decade since the launch date of IBAMA`s licensing and before the imminent increase in exploration activities in Brazil, it is essential to conduct studies to monitor closely the impact of this type of activity on the marine ecosystem. Thus, this study aims to identify potential impacts that the process of oil and natural gas exploration and production might have on the communication of baleen whales. Data from literature on bioacoustics and ecology of these animals were linked with technical-scientific data regarding this type of activity. 310 documents related to the topic were analyzed. Among them only 81 documents are of academic origin, and the others mostly action plans and reports from government agencies. 80% of the documents do not have any species as a focus, and in the remaining 20%, 17% were focused on the Greenland Whale (Balaena mysticetus) and 22% on the gray whale (Eschrichtius robustus). The main impacts identified in this study were the increased frequency and amplitude of vocalization, reduction or cessation of more elaborate songs and masking problems

The main objective of this study was to perform a temporal analysis of land use and cover of Itirapina – São Paulo estate, Brazil, for 1962, 2000 and 2008 scenarios, indicating the rate of change in native vegetation and contextualizing its modifications. Based on photointerpretation performed by supervised classification using the method of Bhattacharya, the thematic classes were mapped and characterized in an area equivalent to 56400 hectares. Using remote sensing technologies and geographic information systems, was structured and implemented a georeferenced and relational database, allowing the analysis of the size of the area occupied. The results showed that the expansion of cultivation of cane sugar and reforestation in the past 45 years has been conditioned the fragmentation of natural vegetation cover in the city, which fell by 34793 ha (61,7%) in 1962 to 9765,2 ha (17,3%) in 2008, with the loss of 25027,8 hectares.
