1. Avaliação quantitativa e qualitativa do emprego de paredes como nova perspectiva para captação de água de chuva
RESUMO A poluição dos mananciais de abastecimento e a necessidade de se buscar água, cada vez mais distante, agregam à água tratada alto valor monetário, sendo a captação e a utilização da água de chuva uma forma de reduzir custos. Nos grandes centros urbanos, ocorre a formação de ilhas de calor, as quais favorecem a ocorrência de chuvas convec

2. Effects of the silica nanoparticles (NPSiO2) on the stabilization and transport of hazardous nanoparticle suspensions into landfill soil columns
Abstract This study evaluates the stability and transport behaviors of hazardous nanoparticles into soil landfills using experimental procedures to simulate the effects of natural silica nanoparticle suspensions during their percolation into the soil layers of municipal waste landfills. For this, we prepared stabilized suspensions of nanoparticle oxides cont

3. OUTDOOR CULTIVATION OF Scenedesmus obliquus BR003 IN STIRRED TANKS BY AIRLIFT
ABSTRACT: The use of microalgae as a source of raw material for biofuel production has been highly targeted. Compared to other biological options for the capture and use of CO2, microalgae crops have the following advantages: high productivity, lack of competition with feed and food-based products, use of unproductive and non-arable land, and allowance of th

4. EVALUATION OF LIMESTONE IMPURITIES IN THE DESULFURIZATION PROCESS OF COAL COMBUSTION GAS
Abstract Limestones have been used to capture SO2 emitted during the combustion of coal for decades. However, due to the complexities of the variables involved in this process, many issues are still being studied. Some tests were performed in a fluidized bed reactor, which was used to evaluate the performance of the limestones in the bed for flue gas desulfu

5. THE USE OF A HIGH LIMESTONE CONTENT MINING WASTE AS A SORBENT FOR CO2 CAPTURE
Abstract In this work, a high limestone content waste was evaluated as a potential material for CO2 capture. The influence of calcination conditions on the CO2 capture capacity was evaluated using 5 cycles of calcination-hydration-carbonation reactions. A Central Composite Design of Experiments was set using calcination temperatures and time as variables. Th

6. A NEW MATHEMATICAL MODEL FOR THE CUTTING STOCK/LEFTOVER PROBLEM
ABSTRACT This paper addresses the cutting stock/leftover problem (CSLP), which differs from the ordinary cutting stock problem (CSP) by retaining stock leftovers that can be cut in the future to meet new demands. Therefore, leftovers are not considered waste in the current period. A new mathematical model for the CSLP is presented to capture a well-used stra

7. Transferência de metano no sentido gás-líquido com vistas ao atendimento da demanda carbonácea da desnitrificação de esgoto sanitário
This work presents a simulation of a hybrid system for waste water treatment, in order to explain the possible use of a carbon supply on denitrification from the methane produced in an anaerobic reactor and transferred to the liquid mass of a reactor that would be removing nitrogen. It was used the biogas produced in a UASB reactor, that passed through a sto

8. Reuso não potável de água em edifícios
Knowing the primary role of drinkable water for the survival of living beings, and realizing that every day concerns about the future as a result of this reduction in the world increases. It is critical that there are initiatives that have a goal of reducing the consumption of per capita drinkable water without causing drastic changes in the habits of its us

9. Dimensionamento de um sistema de exaustão local em uma indústria moveleira / Design of an Local Exhaust System in a furniture industry
A fabricação de móveis está relacionada a uma expressiva geração de resíduos, principalmen-te nas etapas de beneficiamento da madeira. No entanto, raramente essas unidades de produ-ção dispõem de um plano para captação dos mesmos, impondo ao trabalhador condições ina-dequadas para realização de suas atividades. O trabalho apresenta o projeto

10. Alocação econômica de recursos naturais no contexto de bacia hidrográfica : aplicação na bacia do rio Sangão em Santa Catarina
The environmental impacts caused by natural resources exploration may cause damages to third parties, since these agents¿ actions harm the environment and, in some cases, make the existence of other activities unfeasible. This context includes coal mining and irrigated rice cropping. Coal mining and beneficiation make possible the contact between water and

11. MECANISMO DE DESENVOLVIMENTO LIMPO: UMA PROPOSTA PARA SUSTENTABILIDADE DO ATERRO SANITÁRIO DE GOIÂNIA
In the face of climate change and its catastrophic effects, reported daily in the media, the Kyoto Protocol is an international agreement that determined, based on the principles of common but differentiated responsibilities and the polluter pays, that industrialized countries reduce their emissions greenhouse gases, a general average, by 5% to the levels of

12. Distribuição espacial e dinâmica temporal da alga epizoária Basicladia chelonum associada ao cágado Phrynops geoffroanus no rio Uberabinha, Minas Gerais
Studies were developed about a population of Basicladia chelonum epizoic algae over the Phrynops geoffroanus turtle carapace captures in an urban area of Uberabinha River, city of Uberlândia, MG (185434,5"S e 481820,4"W). The fieldwork was accomplished during the morning, in the middle and end of each season, from August 2004 to June 2005, totalizing eight
