1. Ecologia Política da comida e nutrição em duas comunidades quilombolas do Vale do Ribeira (Estado de São Paulo, Brasil) / Political Ecology of food and nutrition for two Quilombola communities from Ribeira River Valley (São Paulo State, Brazil)
Quilombolas are African slave descendants. The Ribeira Valley is one of the most important areas of concentration of Quilombos in Southern Brazil. The Ribeira Quilombolas are settled in remote areas along the Ribeira River system covered by Atlantic rain forest vegetation, one of the worlds biodiversity hotspots. Since the first settlements (18th Century), t

2. Behavior of nonwoven geotextiles impregnated with asphalt emulsion used in anti-reflective cracking systems / Comportamento de geotêxteis não tecidos impregnados com emulsão asfáltica usados como sistema anti-reflexão de trincas
The use of geosynthetics in roadway systems has received considerable attention over the past decades. Paving fabrics have been used for rehabilitation of pavements to reduce propagation of cracks and to extend pavement life. In addition, the success of this technique depends directly on the understanding of the geotextiles behavior when impregnated with asp

3. Influence of subsurface drainage in the service life of roadway pavements. / Considerações sobre a drenagem subsuperficial na vida útil dos pavimentos rodoviários.
There has been verified, in practice, that the absence of pavement drainage is one of the main factors of early degradation of pavements. More, there are few procedures of design and performance analysis that effectively consider the damage of water during the design period. However, foreign experiments and researches do not establish a reliable correlation

4. Decision model for prioritization of urban roadways candidate to pavement maintenance and rehabilitation activities / Modelo de decisão para a priorização de vias candidatas às atividades de manutenção e reabilitação de pavimentos
The development of conservation programs, starting from the previous knowledge of pavements condition, makes possible to maintain certain quality levels in the roadway system. However, in a lack of budget scenario, to achieve those quality levels the decisions have to be taken considering a pavement maintenance and rehabilitation (M&R) prioritization program

5. DEVELOPMENT OF AN IN SITU THERMAL DESORPTION SYSTEM FOR THE REMEDIATION OF CONTAMINATED SITES / DESENVOLVIMENTO DE UM SISTEMA DE DESSORÇÃO TÉRMICA IN SITU PARA REMEDIAÇÃO DE ÁREAS CONTAMINADAS
This dissertation refers to the development of an in situ system devised to remediate soils contaminated with organic compounds. The system consists basically of a thermal probe capable of heating the soil matrix through radial flow and a thermal oxidizer that treats the resulting gases emissions. The system clearly reached the design aims. The thermal probe

6. Evaluation of in-situ bearing capacity of soils in road buildngs through the Dynamic Cone Penetrometer : experimental study / Avaliação da capacidade de suporte de solos "in situ" em obras viarias atraves do Cone de Penetração Dinamica : estudo experimental
This research establishes a correlation among the strength or supporting values of the tests: CBR (California Bearing Ratio) versus DCP (Dynamic Cone Penetrometer), accomplished with the soil originating from no-paved roads inside of the Campus of UNICAMP. The Cone of Dynamic Penetration (DCP) it is characterized as an equipment simple, portable and of low c

7. Aplicação de geoprocessamento para o aumento da eficiência de percurso em operações agrícolas na cultura da cana-de-açúcar (Saccharum spp.). / Aplication of geoprocessing for increase the way eficient on the agricultural machines operations on the sugar cane (Saccharum spp.) crop.
The use of machines and agricultural implements in cultures annual or semi-perennial in Brazil is one of the factors that more demands financial resources, due to the cost in fuels, labor and machinery depreciation. Besides, if badly used, can happen environmental damages, such as erosion and compacting soil. Precision Agriculture is growing in Brazil and it
