Design gráfico da pluma de contaminação por compostos orgânicos voláteiss utilizando software CAD na investigação de passivo ambiental em um posto revendedor de combustíveis em Natal/RN

Among the potentially polluting economic activities that compromise the quality of groundwater are the gas stations. The city of Natal has about 120 gas stations, of which only has an environmental license for operation. Discontinuities in the offices were notified by the Public Ministry of Rio Grande do Norte to carry out the environmental adaptations, among which is the investigation of environmental liabilities. The preliminary and confirmatory stages of this investigation consisted in the evaluation of soil gas surveys with two confirmatory chemical analysis of BTEX, PAH and TPH. To get a good evaluation and interpretation of results obtained in the field, it became necessary three-dimensional representation of them. We used a CAD software to graph the equipment installed in a retail service station fuel in Natal, as well as the plumes of contamination by volatile organic compounds. The tool was concluded that contamination is not located in the current system of underground storage of fuel development, but reflects the historical past in which tanks were removed not tight gasoline and diesel

Desenvolvimento de metodologia para avaliação de desempenho ambiental em edifícios adaptada à realidade do Nordeste brasileiro

This research refers to the production of green buildings, defined, mainly, based on the use of sources of alternative energies, smaller emission of pollutant, use of recyclable materials, systems of recycling of the waters, maximization of the natural illumination, preservation of green areas or native, and appropriate quality of the internal air. From the conception of those buildings, it appears the needs of evaluating them, creating the methodologies for the evaluation of environmental performance of buildings. In that way, this work can be divided in two moments: the first one when it identifies the methodologies for the evaluation of environmental performance for buildings existents in the literature, defining their categories, criteria and sub-criteria to be appropriate to the reality of the Brazilian Northeast; and the second one when starting from the analysis of the systems of existent evaluation. It defines a methodological base and it generates a new evaluation system, denominated MEDACNE (Methodology of Evaluation of Environmental Acting for Construction in the Northeast). In that moment, the process of framing of the section of the building site is verified under the maintainable optics, stimulated mainly by the pressures of the society - conferences, protocols and agreements. Finally, the proposed methodology was applied in a case study, a residential building, called Maria José Gurgel , located in Natal-RN, Brazil, for its validation. This methodological proposition should increase the patterns environmental places for the production of new buildings, and it will be a reference guide for architects, engineers and planners to develop their constructions considering the criteria of the sustainability. This study made use of bibliographical research in books and specialized magazines and the analysis of the data was realized in an interpretative way

Integrating strategic and sustainable design approach for innovation process: a cement case study

Global society and technology have changed the relationships of the market. Quality and cost are not the main aspects of any industrial product. On the other hand, design, innovation and sustainability became significant requirements to company’s competitiveness. In this context, the design approach has shown evolutions, integrating social and environmental aspects beside traditional aspects such as technical and economic. Still, design has been becoming a strategic opportunity for companies, improving their competitiveness and increasing their market share. Thus, this research has analyzed the integration of both the Sustainable Design and Strategic Design Coaching (SDC) method in the making decision activities of companies. A cement company (BQMIL) was assigned as case study, in which the previous results have pointed out the significant hole of those concepts to generate Eco-innovation and Eco-Brand to increase its market share, corroborating the expectative of the design team

Desenvolvimento de um sistema computacional para geração automática de mapas de vulnerabilidade como ferramenta de auxílio às ações de prevenção ao derramamento de óleo em áreas costeiras

The northern portion of the Rio Grande do Norte State is characterized by intense coastal dynamics affecting areas with ecosystems of moderate to high environmental sensitivity. In this region are installed the main socioeconomic activities of RN State: salt industry, shrimp farm, fruit industry and oil industry. The oil industry suffers the effects of coastal dynamic action promoting problems such as erosion and exposure of wells and pipelines along the shore. Thus came the improvement of such modifications, in search of understanding of the changes which causes environmental impacts with the purpose of detecting and assessing areas with greater vulnerability to variations. Coastal areas under influence oil industry are highly vulnerable and sensitive in case of accidents involving oil spill in the vicinity. Therefore, it was established the geoenvironmental monitoring of the region with the aim of evaluating the entire coastal area evolution and check the sensitivity of the site on the presence of oil. The goal of this work was the implementation of a computer system that combines the needs of insertion and visualization of thematic maps for the generation of Environmental Vulnerability maps, using techniques of Business Intelligence (BI), from vector information previously stored in the database. The fundamental design interest was to implement a more scalable system that meets the diverse fields of study and make the appropriate system for generating online vulnerability maps, automating the methodology so as to facilitate data manipulation and fast results in cases of real time operational decision-making. In database development a geographic area was established the conceptual model of the selected data and Web system was done using the template database PostgreSQL, PostGis spatial extension, Glassfish Web server and the viewer maps Web environment, the GeoServer. To develop a geographic database it was necessary to generate the conceptual model of the selected data and the Web system development was done using the PostgreSQL database system, its spatial extension PostGIS, the web server Glassfish and GeoServer to display maps in Web
