13. Management of the environmental restoration of degraded areas
The aim of this work was to study ecotechnology for the management of degraded areas originally covered by the Atlantic Rainforest and located at the coordinates 25º31'50''S, 9º09'30''W. The area included 12 islands, each consisting of six jute bags with 20 kg of substrate (cattle manure and soil transposed from forest fragments). In six of these bags, nat

14. Comparação entre mapas de solos obtidos pelos métodos convencional e digital numa área complexa / Comparison between soil maps obtained by conventional and digital methods in complex area
Soil maps are essential for the development of agricultural areas in an economically viable and environmentally friendly manner. So far, Brazil only has soil maps of small scale (1:250,000 to 1:1,000,000), whose use is limited to agricultural and environmental planning at the farm. Despite its importance, in Brazil a few mappings have been carried out by pub

15. Processamento e modelagem de dados geofísicos e imagens ASTER aplicados à interpretação geológica e prospecção mineral na Província Aurífera de Alta Floresta, MT / Processing and modeling of geophysical data and ASTER images applied to geological interpretation and mineral exploration in the Alta Floresta Gold Province, MT
The Alta Floresta Gold Province (AFGP) is located in the central-southern Amazon craton between the limits of the Ventuari-Tapajos (1.95-1.8 Ga) and Rio Negro-Juruena (1.8-1.55 Ga) provinces. In its eastern segment there are more than one hundred gold deposits hosted in volcanic and plutonic rocks and concentrated along the Peru-Trairao Belt in a NW-SE direc

16. CaracterizaÃÃo do uso e ocupaÃÃo do solo e qualidade da Ãgua com utilizaÃÃo das tÃcnicas de geoprocessamento. / Characterization of soil and water quality use and occupation based on geoprocessing technologies applications
the interest of many researchers who have studied the characteristics and environmental realities of agriculture in order to improve its sustainable development. Thus, this trial aimed at characterizing the use and occupation of soil and water quality according to the GIS techniques. Physical parameters as turbidity, temperature were analyzed as well as chem

17. Implications of landforms in connection with soil versus evolution and installation of the tunnels / ImplicaÃÃes da relaÃÃo solo versus relevo na instalaÃÃo e evoluÃÃo de tÃneis
Whereas erosion is a process that detracts from the soil, reducing its productivity or even making impossible the food production in it, it is worth emphasizing the importance of studies on this topic, especially with explanations and solutions to problems found in areas that are degraded by erosive processes. The installation and evolution of this process d

18. Regeneração natural das clareiras antrópicas da Província Petrolífera de Urucu-Coari, AM / Natural regeneration of the anthropogenic gaps of Urucu Petroleum Province Urucu-Coari/AM
We studied the environmental variables and species composition in natural regeneration in 10 anthropogenic clearings in the Urucu Petroleum Province (Urucu-Coari/AM). We used the methodology typical of phytosociological surveys, analyzed Soil samples and measured the distance between the clearings and the edge of the forest. We used Canonical Correspondence

19. Digital soilscape mapping of tropical hillslope areas by neural networks
Geomorphometric variables are applied in digital soil mapping because of their strong correlation with the disposition and distribution of pedological components of the landscapes. In this research, the relationship between environmental components of tropical hillslope areas in the Rio de Janeiro State, Brazil, artificial neural networks (ANN), and maximum
