1. Effect of partial soil wetting on transpiration, vegetative growth and root system of young orange trees
The wetted area fraction is a factor critical to the success of drip irrigation. This study aimed to evaluate the effect of partial soil wetting on transpiration, vegetative growth and root system of young orange trees. The experiment was carried out in a greenhouse where plants were grown in 0.5 m3boxes internally divided into compartments. The wetting of 1

2. Plant cells in the context of climate change
Global warming and its origins triggered the beginning to considerable discussion in the last century. Studies of climate models presented in multidisciplinary scientific reports suggest that anthropogenic activities, particularly the emission of gases from the greenhouse effect, are greatly responsible for the current climate changes. The increase of carbon

3. Potencial uso de serpentinito no armazenamento mineral do CO2
Rising anthropogenic CO2 emissions are considered a major contributor to the greenhouse effect. There are several options for reducing atmospheric CO2 levels, and among these alternatives, Carbon Capture and Storage (CCS) has been identified as an effective and promising approach. This work investigated the feasibility of using serpentinite as a vehicle for

4. Adubação nitrogenada e inoculação com azospirillum brasilense em híbridos de milho / Nitrogen application and Azospirillum brasilense inoculation on maize hybrids
Maize is one of the worlds most important cultivated cereals; however, it presents great challenges for correct fertilization management. Its high nitrogen demand has been the major cause of excessive applications of synthetic nitrogen fertilizers in the crop. As a result, both environmental and economical problems have increased. Therefore, alternative meth

5. DEPLOYMENT OF METHOD FOR ANALYSIS OF STABLE CARBON ISOTOPES (N-ALKANES C1-C5) IN GAS SAMPLES AT LOW CONCENTRATIONS / IMPLANTAÇÃO DE MÉTODO PARA ANÁLISE DE ISÓTOPOS ESTÁVEIS DE CARBONO (N-ALCANOS C1-C5) EM GASES A BAIXAS CONCENTRAÇÕES
The concentration and isotopic composition of n-alkanes C1-C5 has revealed as a powerful tool for interpretation of interesting processes in the oil exploration industry, studies of global climate change, oil biodegradation and carbon cycle elucidation. In this context, studies about methane analysis have been distinguished and multiplied due to the importan

7. Sustainable business: the concept of governance change - application a company in the petrochemical / Sustentabilidade empresarial: o conceito da governança climática aplicação a uma empresa do ramo de petroquímica
With vital significance, the greenhouse effect gases (GEG), as carbon dioxide and methane, among others, retain sun heat in the atmosphere. This fact avoids sun radiation from dissipating, without letting the Planet being warm enough to keep right conditions for live existence of Earth. However, mankind activities are increasing concentration of these gases

8. Potential of the rail-road intermodality in mitigating CO2 emissions : the case of São Paulo state s cargo transport sector / Potencial da intermodalidade rodo-ferroviaria na mitigação das emissões de CO2 : o caso do setor de transporte de cargas do estado de São Paulo
No ano de 2005, no Brasil, cerca de 58% das cargas foram transportadas através de rodovias, enquanto o modal ferroviário transportou apenas 26% das cargas. O desbalanceamento da matriz de transporte de cargas paulista é ainda mais crítica, pois cerca de 88,6% das cargas que circularam pelo Estado de São Paulo foram através de rodovias e apenas 9,5% atr

9. Os créditos de emissões atmosféricas reduzidas e a responsabilidade civil ambiental
Although the problem related to the weather change has been widespread only in the last decades, it is not recent the concern of the international community in the adoption of measures for the mitigation of this change in the ecosystem balance. The Kyoto Protocol, however, comes as the concrete awareness of the need of acting towards the reduction of the gre

12. A New Estimate of the Components of the Earth\ s Longwave Radiation Budget
(...)This thesis aimed at understanding how the longwave radiation emitted by the Earth\ s surface is transferred and partitioned into the atmosphere. In this context, the effects of greenhouse gases, clouds and aerosols on the Earth radiation budget have been addressed. The work has been motivated by the results of Kiehl and Tren berth (1997) - KT97. They h
