1. Análise do comportamento de maciços sanitários e proposta de um modelo de previsão de recalques considerando a parcela da biodegradação
Currently, the understanding of the mechanical behavior in landfills, keeps on being a complex subject, which still depends on more studies. Therefore, this research was developed to contribute to the understanding on the mechanical behavior of the urban solid waste. This work was carried out with the objective at developing a new model of settlement predict

2. Estudo comparativo da aplicaÃÃo de vinhaÃa tratada e in natura em solos sob cultivo de cana-de-aÃÃcar
Brazil is the world leader in sugarcane plantation. Its economical exploration generates residues, standing out the vinasse. Due to the problems of ecological and social order caused by the vinasse, the most plausible solution for its disposition is the application to the soil as fertilizer. However, that application requests studies to guide the management

3. Evaluation of field performance of cover systems at Rio Paracatu Mine (RPM) / Avaliação de desempenho de sistemas de cobertura na mina Rio Paracatu Mineração (RPM)
In view of the RPM need to study soil covering systems and the scientific interest in those studies, two experimental evapotranspirative cover systems were projected and built, one with and, the other, without, a layer of capillary barrier, both with a monitoring system composed by superficial drainage meter, lisimeters to measure infiltration and geotechnic

5. Avaliação de lavagem incompleta de sais em neossolo flúvico utilizando modelagem computacional.
This study has been developed in two locations which are typical of communal agriculture in the Northeast semi-arid, in alluvial valleys: Nossa Senhora do Rosário Farm, municipal district of Pesqueira, in the agreste area of Pernambuco State and another in the municipal district of Belo Jardim-PE. The objective was to evaluate a computational model to simul

6. DINÂMICA DO ENXOFRE NO SISTEMA SOLO E RESPOSTA DAS CULTURAS À ADUBAÇÃO SULFATADA / SULPHUR DINAMIC IN SOIL SISTEM AND CROPS RESPONSES TO SULFATE FERTILIZATION
The conversion of pastures natives to grain production in soils with low clay and organic matter levels and/or the non-replacement of the exported sulfur by crops could cause a decrease on the availability of this nutrient to plants, whether the sulfur atmospheric depositions are low. There are few informations about the atmospheric contribution for soil fer

7. Potato (Solanum tuberosum L.) and lettuce (Lactuca sativa L.) sensibility to water excess in soil. / Sensibilidade das culturas da batata (Solanum tuberosum L.) e da alface (Lactuca sativa L.) ao excesso de água no solo.
This work had as objectivies determinating the effects of root system flooding in three stages of growing of potato and lettuce crops, identifying the minimum water-table drawdown velocity necessary to avoid yield reductions and obtaining relations between relative yield and stress day index caused by excess of water in the soil. For these purposes two exper
