Geotecnologias para a análise da bacia hidrográfica do Córrego Wenzel - Rio Claro/SP: proposta de gestão de recursos hídricos

The expansion of urban in medium-sized citie, increase the importance of action planning and management of natural resources, among which water is the most important. Such action should include the integration of physical and man-made elements involved. In this context, it becomesimportant for watershed analysis and the use of geotecnologies. Thus, the objective was to demonstrate the contribution of the geo, as a tool for managing a river basin, allowing the integration of physical data and the analysis of anthropogenic environmental scenarios in urban areas. The area chosen, the basin of the Wenzel, is located in Rio Claro / SP, a city whose urbanization process has been intense and continuous. Thematic maps were generated from the physical environment: soil, slope and geological, as well as maps of land use. With regard to land use maps, these were drawn from the visual interpretation of material aerophotogrammetric, considering the years 1995 and 2010, performing an evolutionary analysis. It was observed that the area presents small variation in the physical and structural aspects, with lithological and geomorphological formation favoring the occurrence of floods, erosion and siltation. These processes are accelerated by the forms of land use, with intense urbanization during the period between 1995 and 2010, and poor preservation of permanent preservation areasand. In the floodplain areas there is a high waste disposal is the most notable environmental problem

Levantamento e censo de aves e mamíferos cinegéticos no Parque Estadual Turístico do Alto Ribeira (PETAR), SP

Nas florestas Neotropicais, os mamíferos podem desempenhar papéis importantes como predadores e/ou dispersores de sementes, polinizadores, frugívoros, folívoros ou até mesmo predadores de topo e, por isso, são importantes para a manutenção e regeneração das comunidades biológicas. Os objetivos deste trabalho foram: (i) realizar um levantamento da diversidade de espécies de aves e mamíferos cinegéticos no PETAR, (ii) estimar a abundância relativa, densidade, biomassa e tamanho populacional das aves e mamíferos mais avistados, (iii) comparar a diversidade e abundância das espécies estudadas em dois núcleos com diferentes pressões antrópicas. A área de estudo esta localizada na Serra da Paranapiacaba, que é a segunda maior área protegida do estado de São Paulo, possuindo mais de 125 000 ha, onde quatro Unidades de Conservação estão conectadas (Parque Estadual Turístico do Alto Ribeira, Parque Estadual de Intervales, Parque Estadual de Carlos Botelho e Estação Ecológica Xituê). Ligadas a Serra do Mar, estas UC´s formam um grande corredor de biodiversidade que compreende o maior contínuo florestal de Mata Atlântica. O presente estudo segue o mesmo protocolo de amostragem do projeto BIOTA Fapesp (01/14463-05). As espécies alvo da amostragem foram aves de grande porte (Cracídeos, Tinamídeos e Fasianídeos) e mamíferos acima de 1kg, com exceção do esquilo (Guerlinguetus ingrami) que é uma espécie indicadoras de áreas defaunadas. Para o levantamento qualitativo (riqueza) foram utilizadas identificação de pegadas, carcaças, rastros e observações ad libitum. Já o levantamento quantitativo (abundância, densidade, biomassa e tamanho populacional) foi obtido pelo método de transecções lineares, em que para cada indivíduo observado foram obtidas a distância perpendicular animal-trilha, horário do avistamento, número de indivíduos e sua localização...

Educação no campo e educação rural: distinção necessária para compreensão da realidade geográfica

The work’s objective is to point out the difference between rural / urban and country side / city, drawing on the historical process of formation of the terms and analyzing the current dichotomous and continuous, to clarify the concepts of education in rural and rural education, in an attempt to differentiate these types of education in accordance with the schools. Also works with the different conceptions of children, adolescents and youth of the rural that are mostly students from schools in the 1st and 2nd grade. On empirical evidences, we try to adapt the concepts studied in the School Municipal Agricultural Engenheiro Rubens Foot Guimarães, Rio Claro, SP

Ocupação irregular do solo urbano - caso das habitações em encostas: causas e consequências

Uma grande parte da população brasileira reside hoje em locais considerados inadequados, seja pela ilegalidade ou pelo risco contínuo de catástrofes. Todo ano são noticiadas novas tragédias decorrentes dessas ocupações irregulares, exigindo tomadas de providências emergenciais e preventivas por parte dos responsáveis pela gestão do espaço público. A compreensão desse problema exige uma análise histórica da formação desses aglomerados urbanos, ou favelas, verificando os motivos que impedem ou desestimulam a elaboração de leis rígidas e aplicáveis para esses casos, bem como a elaboração de diretrizes de planejamento e projetos que possam ser implantados para solucionar estas questões nos locais necessitados

Avaliação da auto-suficiência energética de reatores anaeróbios no tratamento de esgoto sanitário e de água preta

The purpose of this project is to verify whether anaerobic reactors applied to sewage treatment are energetically self-sufficient. This evaluation can be made by balancing the methane produced through the anaerobic transformation stages (hydrolysis, acidogenesis, acetogenesis and methanogenesis) and the reactor energy consumption requirements. The original project included methanogenic activity tests, which could not be performed due to setbacks in the installation of an analytical instrument. Scientific articles about bench- and full-scale anaerobic reactors were investigated instead. An average substrate-to-methane conversion efficiency of 58,2±18,6% was found for the bench-scale reactors and higher efficiencies (89,2%) were found for the cases which had higher Organic Loading Rates (OLRs) values. The average energy output was 0,013 kWh/Lsewage, value unable to meet the energy needs for the reactor operation, considering equipments normally used such as temperature controller. This balance can become positive if few hypotheses are made, for example (i) to eliminate the use of temperature controller (ii) to alter the operation pattern from continuous to intermittent. Based on energy balance assessment of eight bench-scale reactors, it was observed that the implementation of a system for biogas utilization is not energetically feasible. However, interesting results were found for a full-scale sewage treatment plant, ETE Ouro Verde – Foz do Iguaçu, PR, Brazil. Even though its substrate-tomethane conversion efficiency was about 10% only, the energy balance was quite positive, with energy consumption of 68 kWh/month and energy production of 660 kWh/month. This analysis leads us to conclude that energy recovery from full-scale sewage treatment plants should be practiced by other plants

Remoção de N-amoniacal em baixas concentrações de oxigênio dissolvido a partir do efluente de frigorífico bovino

This work aimed to develop a biological system for removal of ammonia nitrogen operating at low concentrations of dissolved oxygen. Thus, a biological upflow vertical reactor was built, in which the affluent pass through the support media until the top. Sludge from an anaerobic stabilization pond of a slaughterhouse unit in the city of Presidente Prudente - SP was used as inoculum. Initially the system operated in batch and afterwards in a continuous flow with different HRT. For feeding the reactor, an initial phases was adopted a synthetic culture media, described by Martins (2007), in order to establish the ideal conditions for the development of Anammox bacteria and subsequently, submitted to the system a slugde effluent of slaughterhouse. The results showed significant removal efficiency of N-NH4+, especially in the phase without recirculation of culture media, with an average of 71% removal, with the proportion of removal of N-NH4 +:N-NO2- average 1: 1,69. For the period of operation with effluent from the slaughterhouse, were not obtained satisfactory results, without confirmation of the proliferation of Anammox bacteria in the system, due to the high presences of organic matter in the same confirmed by high concentrations of COD

Estudo sobre fornos de tratamento térmico e propostas de cogeração de energia em usina siderurgica não integrada

Steel industry is a sector heavily dependent on energy, both electrical and thermal. Since the receipt of raw materials to the shipment of finished products to customers, through mergers, casting, rolling, heat treatment, inspection, among others, high amounts of energy are demanded, generating very significant costs to the productive chain in its entirety . Therefore, any alternative that favors the reduction in energy consumption or barateie the cost of this is very welcome. Within this context, this paper aims to make a technical and economic analysis of installing a cogeneration plant in the field rolling in a non-integrated steel mill. Two configurations are proposed plants, with one being the use of heat from waste gases from furnaces existing in the area mentioned and another with the use of heat from waste gases from an internal combustion engine. Both proposals are evaluated technically and later is done the economic analysis, calculating the financial return (pay back) in relation to the investment required, operation and maintenance of the plant

Determinação da freqüência natural de eixos utilizando o software excel

This work aims to determine the first natural frequency of rotation shaft by using a basic software, Excel, and to compare it to the values obtained in laboratory. When an axle is submitted to a rotation, depending on the rotational frequency used, the axle can enter a state of resonance, in which the amplitude of vibration becomes rather high. The frequencies in which the resonance is observed depends on several parameters of the axle, including the number of concentrated masses associated to the axle. Thus, to obtain a computer program of easy use and access, which can preview the frequency of resonance of an axle in rotation with ‘n’ numbers of concentrated masses it has been studied how the frequency varies with each of these parameters. The computer program and the analyses have been made using the Rayleigh Method, which allowed the transformation of a continuous system to discrete through the theory of finite elements, which has proved that, the bigger the number of divisions of the shaft taken into consideration in the calculus of the natural frequency, the more this value gets close to the real value. The results obtained have been considered satisfactory once these have gotten close to the theoretical results expected

Paleo expo: uma exposição sobre a história da vida na terra para alunos do ensino fundamental

A importância do estudo da paleontologia está no seu caráter integrador, reunindo conhecimentos de várias áreas, o que pode contribuir para que os alunos do ensino básico entendam a história da vida no planeta, encarando a evolução como um processo contínuo e bem evidenciado no qual também estamos inseridos. No contexto de pequena presença do ensino da paleontologia na Educação Básica, outros espaços de educação não formal ganham força na transmissão desses conhecimentos à população e, dentre estes espaços, na área da paleontologia, encontram-se as exposições de fósseis. Estas permitem que os conhecimentos desenvolvidos na universidade e que normalmente ficam restritos ao âmbito universitário sejam levadas ao conhecimento de um grande número de alunos, contribuindo para a formação e alfabetização científica. A partir desta perspectiva, o presente estudo teve como objetivo o desenvolvimento e a avaliação de uma exposição de fósseis e réplicas para os alunos do ensino básico da rede pública das escolas de Botucatu e região. Através dessa exposição, chamada Paleo Expo, pretendeu-se que os alunos conhecessem a história da vida na Terra, tivessem contato com os principais eventos evolutivos e entendessem a evolução como um processo contínuo e bem evidenciado, contribuindo para o enriquecimento dos conhecimentos dos visitantes, aguçando a curiosidade e gerando reflexões. A exposição, destinada a alunos de sexta a oitava series do ensino fundamental, priorizou a participação ativa dos alunos e contou também com atividades complementares, que consistiram em um jogo educativo e uma apresentação de informações sobre como são realizadas as pesquisas em paleontologia. A Paleo Expo, de um modo geral, atingiu seus objetivos e os alunos se mostraram estimulados e participativos. Pode-se considerar, pelos dados coletados, que a experiência...

A produção do espaço em cidades pequenas: o caso de Emilianópolis

In this paper we analyze some factors of urban life in small towns, among which we can highlight the political, economic and social, more specifically in the city of Emilianópolis, and its great dependence on other cities. The number of small towns has grown in recent years and this study shows is of great importance for understanding the differences that exist between them and the larger cities. Where Emilianópolis, having its location next to a city average (Presidente Prudente), we realize that its existence depends largely on the proximity of that with a bigger city. The study looked at the origin of the city, its spatial structure, its insertion into the urban network and the degree of dependence with other cities, notably Presidente Prudente, which generates a steady stream of people moving from Emilianópolis to study, work, leisure, between others, besides the permanent migration, which often makes life easier for those residents. With this study, we intend to demonstrate how Emilianópolis is inserted into the urban network, how is its interaction with other cities and how they live their inhabitants

Microalgas na Produção de Biodiesel: Extração e Composição Lipídica

The uninterrupted rise in emission of greenhouse gases open way to the use of biofuels, due to politics that focus on fuel safe, clean and renewable. The use of microalgae for biodiesel production has been described as one of the most promising sources of biomass for biofuels. The aim of this study was to evaluate the extraction and lipid profile of the microalgae Dunaliella tertiolecta, Isochrysis galbana and Tetraselsim gracilis. The extractions were performed with solvents chloroform /methanol and petroleum ether. The lipid profile was analyzed by gas chromatography after transesterification.The petroleum ether showed more efficiency in the extraction, the best result obtained was in the microalgae D. tertiolecta with 19.52% of lipid. The lipid profile analysis indicated a biodiesel stable to oxidation and elevated viscosity

O espaço do idoso na cidade

Em muitos países, principalmente os mais desenvolvidos, o aumento da expectativa de vida é um fato constatado através das pesquisas públicas. No Brasil, a idade máxima atingida pela população é, em média, de aproximadamente setenta e dois anos. Porém, estes números foram resultado de um crescimento contínuo e persistente da expectativa de vida no país e que continua acontecendo. São consideradas idosas as pessoas com mais de sessenta anos. No Brasil, já existem investimentos em pesquisas e projetos voltados para os idosos, com necessidades peculiares, os recursos e equipamentos adequados para essa parte da população, mas não são suficientes. O projeto em questão busca resolver com a Arquitetura e o Urbanismo muitos dos problemas enfrentados na terceira idade. Sem excluir nenhuma faixa etária da população, mas dando ênfase aos idosos, o projeto estuda um espaço público já existente para dar-lhes acessibilidade e estrutura de serviços para serem realizadas as atividades de rotina e lazer. O projeto terá vários focos dentro de uma área dos bairros de Pinheiros e Vila Madalena, na cidade de São Paulo, para promover uma maior e mais eficiente inclusão do idoso no espaço urbano. O primeiro foco é uma praça que terá equipamentos que ajudam no físico, na saúde e no entretenimento dos idosos. O segundo é a revitalização da Rua Mourato Coelho, que liga a praça com a Feira Livre, além de todos os comércios e atividades propostos na rua e até o próprio bairro, atraindo mais atenção à praça. Este comercio, próximo, poderá proporcionar atividades de trabalho para os idosos, sendo um terceiro foco de tentativa de inclusão deste contingente no espaço urbano

Estatuto do índio, direito indígena e impacto ambiental: aldeias Guarani do Jaraguá (SP)

In Brazil, there are three main codes that surround the issue of right or possession of various lands according to concepts of ownership or purchase. When it comes to indigenous issues in Brazil is difficult to say which legal code applies more fairly the native population of the country. In the case of the Indians who have their reserves near urban areas there is such a conflict of laws becomes more evident and takes even greater than in other regions of Brazil. As is the case in the indigenous villages of the District of Jaragua in Greater São Paulo, the Tekoá YTU and Tekoá Pyau. The two villages are located in northeastern São Paulo and currently are surrounded by continuous growth and disorderly city of Sao Paulo while their inhabitants fight to preserve the customs and traditions of the Guarani people. They prevail on the City Statute (2001), the Indian Statute (EDI) Environmental Laws and the National Council of Environment (CONAMA) and the Forestry Code, the latter solely because they are near the State Park Jaragua - area environmental preservation

Tornar-se professor: desvelando a atuação docente no início do exercício da docência

This research, based on authors such as Was (1999), Guarnieri (1996 and 2005), Freitas (2002 and 2007) argue that the understanding of teacher education as a complex continuum aimed at understanding the initiation of the educational performance in the first five years of professional practice, by analyzing the history of teaching teachers early in their career. As we contemplate the specific objectives of interest to examine the training received to enter and work in the classroom and the experiences in teaching at undergraduate students. To perform the empirical study we adopted the use of semi-structured, guided by an outline of issues significant to the conduct of the respondents' narratives. The main results can highlight the difficulties encountered at the beginning of the educational performance are recurrent, data analysis shows that there is a significant increase in the duties of the teacher. With the study arrives at the premise that we must rethink the quality and structure of training courses aimed at improving the quality of performance of professional education, but for this to occur there must be deepening of studies and improvements not only in initial training and in continuing education courses. It is understood here that the training is not solely responsible for the current educational scene, which encompasses the question of the beginner there are many issues to be studied, such as public policies, structuring the curriculum, pay, but the training is beginning to there are faculty prepared to act
