1. FIXAÇÃO DE CO2 EM EFLUENTE SALINO DE INDÚSTRIA PETROQUÍMICA
In various industrial processes, such as the process of obtaining potassium by solution mining or in the oil industry, fuels are burnt concurrently to the formation of saline effluents. The opportunity to sequester carbon through capturing the CO2 from the flue gas by carbonation of these effluents and reducing the potential of scaling of the water is eviden

2. Comparison of carbon sequestration potential in agricultural and afforestation farming systems
In the last few decades, many forests have been cut down to make room for cultivation and to increase food or energy crops production in developing countries. In this study, carbon sequestration and wood production were evaluated on afforested farms by integrating the Gaussian diameter distribution model and exponential diameter-height model derived from sam

3. O Protocolo de Kyoto e o mercado de crédito de carbono: estudo de caso das emissões de gases de efeito estufa da fábrica de combustível nuclear pertencente às Indústrias Nucleares do Brasil no ano de 2008 / The Kyoto Protocol and the carbon credit market: case study of emissions of greenhouse gases from nuclear fuel factory belonging to the Nuclear Industries of Brazil in 2008
This dissertation discusses issues related to intensification of climate change by anthropogenic causes for the evolution in use of natural resources, innovations in production processes, economic, social, cultural, political and especially environmental. Approaches marketing of carbon credits through projects of Clean Development Mechanism (CDM), one of the

4. Desenvolvimento de uma metodologia para a estimativa de biomassa e de carbono em sistemas agroflorestais por meio de imagens orbitais / Development of a methodology to the estimation of biomass and of carbon in agroforestry systems for middle of orbits
Remarks indicate that naturals systems of the Earth are being affected for transformation about the ability of diverse region. Within the causes these changes, detach the emission of CO2 (Carbon Dioxide) way alteration in land use and land cover. The Amazonian region, in function of the occupation trajectory has received attention of the scientific community

5. EMISSÕES DE CO2 DO SOLO SOB PREPARO CONVENCIONAL E PLANTIO DIRETO EM LATOSSOLO VERMELHO DO RIO GRANDE DO SUL / SOIL CO2 EMISSIONS IN CONVENTIONAL AND NO-TILL SYSTEMS IN A RHODIC HAPLUDOX IN RIO GRANDE DO SUL
Climatic change is associated with the increase of greenhouse gases (GHG) concentration, including carbon dioxide (CO2). Among the most important strategies to decrease global warming are decrease emissions and increase biological capture of CO2 through carbon sequestration in the ecosystems. Therefore, soils are fundamental to this strategy because dependin

6. Sequestro de dioxido de carbono em fotobiorreatores / Carbon dioxide sequestration in photobioreactors
A conversão fotossintética de dióxido de carbono em fotobiorreatores foi investigada com o propósito do desenvolvimento de um sistema biológico para o seqüestro de carbono. O processo utilizado consiste na transferência de dióxido de carbono gasoso para a fase líquida de um reator, no qual este composto é convertido em produtos do metabolismo fotos

7. Sugarcane and climate changes : effects of CO IND. 2 enrichment atmosphere in growth, development and carbohydrate metabolism in Saccharum ssp / A cana-de-açucar e as mudanças climaticas : efeitos de uma atmosfera enriquecida em CO IND. 2 sobre o crescimento, desenvolvimento e metabolismo de carboidratos de Saccharum ssp
Desde o início da Revolução Industrial as concentrações de CO2 atmosférico aumentaram em cerca de 30% e estimativas apontam que esta concentração poderá atingir aproximadamente 720 ppm até a metade deste século. Estudos sobre o efeito do alto CO2 no desenvolvimento de diversas espécies vegetais já foram realizados, porém poucos com espécies de

8. RelaÃÃes alomÃtricas em Leucaena leucocephala (Lam.) De Wit / Allometric relations for Leucaena leucocephala (Lam.) de Wit
Concern with increase carbon dioxide emissions has fostered several studies throughout scientific knowledge. The greenhouse effect is recognized as necessary for Earth surface colonization. However, modern day carbon dioxide and other greenhouse effect gases are blamed for atmosphere warming and its catastrophic effects. Both the Kyoto treat and the policy o

9. Fitomonitoração e modelagem de fotossíntese em jatobá (Hymenaea courbaril L.) com redes neurais artificiais. / Phytomonitoring and modelling of photosynthesis in jatobá (Hymenaea courbaril L.) with artificial neural.
The increases in greenhouse gas concentrations, mainly carbon dioxide, and the climatic changes have become important scientific, economic, and political subjects in the past years. The Kyoto Protocol establishes the Clean Development Mechanism, which grants carbon credits for projects that promote the sequestration of carbon in developing countries. Therefo
