Estudo da elaboração do plano de descomissionamento para desativação de empreendimentos

Deconstructions, although hardly covered in Civil Engineering courses, are a very important field of study. Due to numerous factors, such as obsolescence, buildings life cycle comes to an end leading to their deactivations. Decommissioning is a process that intends to plan the hole deactivation by providing the cleaning of contaminated areas, avoiding risks to public health, as well as promoting a screening of generated waste, whether dangerous or not, offering their correct disposal or even reuse when possible. Decommissioning must be developed by a plan that covers from the recognition of the area until its releases to other uses. When this procedure is appropriate, attention must be paid to the cost effective of its implementation and to the cleaning standard that the plan intends to reach. The execution of the service allows to reuse the area, becoming productive again

Ecotécnicas aplicáveis á construção civil no Brasil

This work approaches the main eco-efficient techniques and materials that can be used to ensure the proper functioning of the habitat with the main objective of preserving energy and reducing the ecological impact. The harnessing of energy to run a house using materials in a correct way makes it possible to achieve the goals related to its rational use. So, the more consolidated techniques need to be studied separately to determine the global effect on housing. The results obtained, with the aid of standard NBR15220 ABNT, were a series of ecotécnicas that can be used in 8 relatively homogeneous zones. This study was made to create a public awareness of the current environmental problems that society is facing nowadays and the urgent need to practice responsible use of energy

Potencial de aproveitamento de agregados reciclados de resíduos da construção e demolição

CONAMA Resolution 307 / 02, in Article 4, states that the primary goal of those involved in the reuse process of construction and demolition waste is not the generation of such wastes, secondarily is the reduce, reuse, recycling and proper disposal of such material. The disposal problem of large volumes of waste generated coupled with the scarcity of natural resources and environmental degradation involved in the extraction process of such materials resulted in several studies, that after many analyzes proposed various forms of reuse and recycling . The NBR 15.116/04 provides requirements for the use of recycled aggregates in paving and concrete without structural function. This work aims to show the usage potential of recycled aggregates from waste generated in construction and demolition sampled Group AB Areias, Pindamonhangaba (SP) in order to meet the standards in Brazil, as well as the environmental contribution by reducing the use of raw materials extracted from nature. After stabilization and particle size analysis of the California Bearing Ratio and Proctor, obtained mixtures of recycled aggregates showed higher values submitted by the minimum standards related, with excellent potential for use in paving

Diagnóstico dos resíduos gerados nas oficinas mecânicas de veículos automotivos do município de São Carlos-SP

The mechanical garages do varied types to activities related to the reparation from vehicles such as change from Motor oil, change and cleaning from car pieces, motor rectification, among others. These activities generate different kinds of waste and wastewater that when disposed in an inappropriate way can pollute the environmentand cause risks to the public health. Despite the environmental issues that involves these enterprises, they aren´t object of environmental licensing and there are any rules that regularizes their activities with the goal of these possible environmental impacts mitigation. The environmental diagnosis proposed by the present work has as goal the knowledge of the possible environmental aspects and their effects in the environment, for establishing control measures and from that to generate subsidy for environmental normatization of the sector in the municipal level. Furthermore, it should also define practices as waste production reduction, separation of them at the generator source and convenient final disposal, as well as wastewater production reduction and treatment of them before its launching in the wastewater network. The environmental diagnosis was based on a survey realized in garages from the city of São Carlos – SP, in order to define the more important characteristics of this activity that are related to the environment and public health. From the obtained information from the survey and the interpretation of the data, subsidy for the municipal environment management of the mechanical garages were generated.

Explorando as consequências das preferências alimentares dos brasileiros sobre o uso da terra e emissões de CO2

O consumo de carne bovina pela população brasileira está relacionado a aspectos que sejam sociais ou de saúde. Além disso, pode afetar também o nosso meio ambiente, aumentando impactos ambientais. Em se tratando do Brasil, temos uma grande demanda deste alimento, influenciada pelos hábitos alimentares da população, exigindo, por conseguinte, uma grande produção. Através da construção de cenários e modelagem ambiental, este trabalho avaliou algumas das consequências ambientais da pecuária de corte no Brasil. Para tanto, usamos estimativas de consumo da população, produção da carne bovina e também de valores que relacionem o uso da terra com as emissões de gás carbônico para avaliar os problemas ambientais. Contabilizamos as emissões de gases de efeito estufa associadas as mudanças de uso da terra, fermentação entérica e o manejo de dejetos do gado bovino. Obtive que em alguns cenários extremistas como o Con2a as emissões foram no total de 1,77 PgCO2e anualmente. Enquanto no cenário nacional obtive um total de 1,2 PgCO2e das emissões anuais associadas a todos os seus setores. Em nossos resultados notamos a forte influência do nível de consumo de carne e do sistema de manejo nas emissões de gases efeito estufa dos cenários estudados

Modelo de conjuntos fuzzy e de regressão logística para dados de obesidade

Obesidade e comumente definida como um excesso de gordura corporal, porém diante da dificuldade em mensurar tal gordura diretamente, esta tem sido definida como um excesso de peso mais do que um excesso de gordura corporal, que tem como desdobramento a ocorrência de doenças associadas e/ou prejuízos a saúde do indivíduo (4). Atualmente, o excesso de massa corpórea e verificado por meio de um Indice de Massa Corpórea (IMC), que considera o quociente entre o peso corporal (kg) e a estatura elevada ao quadrado (m2). Indivíduos com sobrepeso apresentam IMC de 25 at e 29; 9 kg=m2, e com obesidade apresentam IMC de 30 Kg=m2 ou mais, de acordo com a OMS (1). A identificação das causas da obesidade não é trivial e objetiva. Especialistas reconhecem que a obesidade e uma doença crônica, de difícil tratamento, denominada multifatorial, envolvendo em sua gênese diversos aspectos, entre eles: o consumo alimentar, aspectos ambientais, genéticos, psicossociais, entre outros. objetivo deste trabalho foi desenvolver um modelo baseado em teoria dos conjuntos Fuzzy para a classificação de obesidade levando em consideração as suas causas, e compará-lo com um modelo de regressão logística através da curva ROC. Para estudar as causas da obesidade na população de moradores da região do Distrito Sul de Campinas, foram coletados dados de uma amostra aleatória de 651 indivíuos, por meio de entrevista domiciliar. No primeiro estágio amostral, a partir do cadastro de domicílios residenciais dos agentes comunitários de saúde, foram aleatoriamente sorteados 920 domicílios (15% a mais do inicialmente previsto para cobrir perdas). Foram coletados dados de identificação geral, como: nome, idade, sexo, anos de escolaridade, tipo de ocupação e dados de consumo alimentar. O diagnóstico foi observado através do IMC. Num estudo preliminar, no modelo fuzzy foram consideradas como variáveis... (Resumo completo, clicar acesso eletrônico abaixo)

This work focuses on the analysis of extreme precipitation episode in the city of Rio Claro, held on 24 and 25 February 2010, which caused severe impacts to society, and a victim of drowning due to flooding due to flood in urban stream. Although the temporal concentration of summer rainfall is characteristic of tropical climatic regimes, each year there are issues of social and environmental impacts deflagrated by precipitation events in the city. These findings reinforce the importance of analyzing atmospheric conditions correlated to change in space usage

Efeitos da ocupação e uso da terra na bacia do córrego da Servidão, no cenário de 1995-2006

Urban sprawl developed without adequate urban planning and lack of knowledge about the physical characteristics of an environmental system, results in soil sealing and consequent change in the dynamics of hydrological watershed. Thus, this study aimed to analyze the behavior of the runoff basin Cóorego DA Servidão located in Rio Claro, referring to the year of 1995 compared to the scenario of 2006, compared the different features of urban use logged area. Therefore understanding the dynamics of the flow was possible through the use of software IPHS 1 that allowed through hydrologic models to evaluate the behavior of the surface area investigated, using Spring 4.3.3 software which enabled the classification of land use and software ArcGis 9.3 which was used for the quantification of stretches of water, separated from those that are channeled and those who did not suffer interference from the pipe

Análise da dinâmica do uso da terra e sua interferência em enchentes na área urbana do município de Americana (SP)

Due to an intense process of population growth and urban density in Americana (SP), mainly due to the development of the local textile industry after 1970, there was, concomitant to the occupation of the margin of rivers and streams, soil sealing that increased the level of superficial runoff, triggering frequent floods. Based on the analysis of these processes we investigate the conditions of one densely urbanized area of the county, the Córrego do Parque, in three time series, 1977, 1996 and 2008. Taking as the starting the characterization and spatial distribution of landscape physiography, we prepared thematic letters and synthetic maps digital scale 1:10,000 from photointerpretation of aeroframes. The thematic maps were produced by scanning with subsequent edition using the software Auto-Cad Map. Checking the data and of geographic coordinates with GPS (Global Positioning System). Regarding land use classes, we used the description of the Soil Conservation Service (1975) which allowed us to get the Curve Number parameter, which will be used in hydrologic modeling for verification of flooding (Tucci, 1989). For the process of hydrologic modeling, we used models based on Methodology Object Oriented Modeling Applied to Water Resource Systems, Viegas Filho (1999), using the computer program called IPHS1, which uses models of the Soil Conservation Service (SCS , 2004), for conversion of rainfall-runoff and the spread of excessive rain. The results indicate that increased waterproofing generated by the change in use and occupation over the past decades promoted the increased surface runoff and drainage system overload, increasing the intensity of floods

Medidas de adequação ambiental para indústria de leite e derivados, como requisito para gestão ambiental

The society continues demonstrating its need regarding the products and services, even though it becomes increasingly value the protection of the environment. In this context, environmental management is defined as a management method that emphasizes to continuously improve results and promote sustainable development. Moreover it has as a tool the laws which provide the benchmarks and mechanisms for companies to adapt their activities in such a way that does not alter the quality of the environment. In this sense, in order to propose improvements to a dairy aiming their environmental suitability, a present study was prepared by following the production activities of the enterprise, the raising of standards and applicable legal requirements and environmental assessment for the preparation of an array of aspects and impacts with the task of identifying the most significant according to MOREIRA (2006). The results indicated that some of the impacts of high relevance are related to the generation of wastewater and solid waste, which do not have treatment and / or proper disposal and indeed require intervention for their suitability. Through, these results were drawn up proposals for actions conformation. In addition, they were proposed meeting the requirement for health and safety at work, in accordance with the standard regulations. This study has the function, therefore, propose to the company in question, an environmental management plan that ensures the protection of the environment and health of employees and consequently the improvement of production processes and products

Desenvolvimento regional e sustentabilidade: a indústria intensiva em recursos naturais na região administrativa de Ribeirão Preto

The natural resource intensive industries have moved from center to periphery in Brazil. This shift is related to the environmental impacts generated by this type of industry, as occur biggest benefits to these industries in small towns as tax exemptions and donations of land, and local institutional capacity is lower in pollution control. In the 1970s began, in the state of São Paulo, a process of industrial deconcentration of Metropolitan Region of São Paulo to the inside of state, which generated an intense industrialization of the region of Campinas, Ribeirão Preto, Sorocaba e São José dos Campos. This process of industrial deconcentration had support in state policies restricting new industries in the Metropolitan Region and the creation and financing of infrastructure and improvement of road. This research project aims to verify whether there has been a shift of natural resource intensive industries for the Administrative Region of Ribeirão Preto, as well as aspects of the sustainability of this process

Análise geoambietal para o planejamento de obras civis lineares: uma abordagem por sensoriamento remoto orbital

Construction of linear engineering as, roads, ducts and multiducts as roads, has a strong feature of the diversity of land on which they are deployed. This diversity involves properties geological, geomorphological and structural variety. The purpose of this work is to characterize the physical environment in relation to their ability to support the implementation of civil works linear. To achieve this, the use of orbital remote sensing, in this case, Landsat - TM. Interpretative techniques are applied to images in order to assess the forms of relief and drainage found that they can set properties and have built a favorable meaning or not to implement these works. The results and thematic maps presented in this study allow us to promote the geoenvironmental analysis for the planning phase sustainable linear civil constructions (roads and multiducts)

Análise das alterações temporais dos fragmentos de vegetação no centro experimental do Instituto Agronômico, Campinas, utilizando técnicas de sensoriamento remoto e geoprocessamento

O presente estudo tem como objetivo principal realizar um levantamento temporal das áreas de vegetação no Centro Experimental de Campinas (CEC), uma fazenda de propriedade do Instituto Agronômico (IAC), a partir de técnicas de geoprocessamento e fotointerpretação. O local de estudo situa-se no município de Campinas - SP, e a área em questão foi escolhida por estar situada dentro de uma propriedade do estado e por apresentar uma grande mudança histórica no que diz respeito à vegetação. Também por que, apesar de ser um centro de experimentação agrícola, esse estudo demonstrara como num intervalo de quarenta anos a consciência ecológica muda radicalmente dentro do Centro. Para a realização deste trabalho, foram utilizadas fotografias aéreas digitais da fazenda dos vôos referentes aos anos de 1964, 1972 e 2002, todas de propriedade do acervo do Laboratório de Geoprocessamento do Centro de Conservação dos Solos do IAC. Alem da foto de satélite da fazenda obtida no software Google Earth, com data de 2006. Analisando imagens e mapas, observou-se como a área vegetada aumentou no Centro Experimental de Campinas nesse intervalo de quarenta e dois anos, passando de 7,55% (52.383 ha) em 1964 para 34,13% (236,497 ha) da área total do centro em 2006. Também pode-se ver que hoje há uma preocupação muito grande com a manutenção e conservação dessas matas.
