1. Natural Fertility and Metals Contents in Soils of Rio Grande do Sul (Brazil)
ABSTRACT: The parent geological materials and formation factors influence the chemical, physical, and mineralogical properties and composition of the soil. Therefore, the aims of this study were to determine the chemical and some physical and mineralogical properties of the soil useful for agricultural practice; to determine the natural contents of the semit

2. Evaluation of chemical and mechanical resistance of virgin and recycled poly (ethylene terephthalate) and poly(methylene oxide) when applied as gravel pack in petroleum wells
AbstractNowadays more and more unexpected uses for common materials have been observed, especially when recycled polymers are concerned. In this work, the viability for application of virgin and recycled poly(ethylene terephthalate) (PETvir and PETrec, respectively) and also poly(methylene oxide) (PMO) as granular materials (gravel) for gravel packing in san

4. Mapeamento do potencial de instabilização de taludes rodoviários usando SIG e seções geológico-geotécnicas de campo com aplicação na rodovia SP-310 / Mapping of the potential of instabilization of road slopes using Sig and geological-geotecnical sections of field with application in highway SP-310
The present study developed a methodology for mapping of instability potential of road slopes. It was used, for in such a way, GIS (Geographic Information System) and obtained geologic-geotechnical of detail sections in surface surveys. This methodology was used in a section of Road Washington Luís (SP-310), under two different conditions. First, it was app

5. Geological-geotechnical characterization of the uncontrolled sanitary landfill of São Carlos-SP / Caracterização geológico-geotécnica do lixão desativado de São Carlos-SP, com auxílio da geofísica
Unfortunately the brazilian cities, in its majority, discharge its domestic solid wastes without any control, which produces grave consequences such as contamination of the air, earth, and both superficial and the groundwater. This work carried out a geological-geotechnical characterization and geophysical studies of the uncontrolled sanitary landfill of Sã

6. Zoneamento geoambiental com auxílio de lógica fuzzy e proposta de um geoindicador para caracterização do meio físico da Bacia do Rio do Peixe / Geoenvironmental zoning using fuzzy logic and proposal of a geoindicador to characterize Rio do Peixe basin environment
This study presents a methodological technique to characterize environmental restrictions and aptitudes considering continuous variation in the attributes and gradation in contato between units. Fuzzy logic procedures were used to generate representation of contact gradation for rocky substratum and unconsolidated materials maps. Continuous attribute variati

7. Mapeamento geotécnico preliminar em escala de semi-detalhe (1:25.000) da área de expansão urbana de Uberlândia-MG / Preliminary engineering geological mapping in a scale of semidetail (1:25.000) of the urban expansion area of the Uberlândia - MG
O presente trabalho apresenta o mapeamento geotécnico preliminar em escala de semidetalhe (1:25.000) realizado na porção peri-urbana da cidade de Uberlândia oeste do estado de Minas Gerais, abrangendo uma área aproximada de 303 Km. A realização deste trabalho teve como objetivo geral gerar subsídios ao planejamento do uso e ocupação do meio físico

8. Estudo geoambiental da bacia do Rio Pardo, a partir da compartimentação em Ottobacias - Escala 1:100.000 / Geoenvironmental study of Pardo River basin from Ottobacias compartimentalization - scale 1:100.000
This work presents a method of analysis and compartimentalization of the environment that combines the subdivision in Ottobacias (Pfafstetter, 1987) with engineering geological mapping. Initially the basin was divided in 9 areas, represented by the 4 larger Pardo river sub-basins and the remaining 5 areas called interbasins. Furthermore, the characteristics

9. Geotechnical mapping and analysis of erosion process at Tuncum creek watershed, São Pedro-SP, scale: 1:10.000 / Mapeamento geotécnico e análise dos processos erosivos na bacia do córrego Tuncum, São Pedro-SP, escala 1:10.000
This work aims to analyze the main factors related to the erosion processes in the Tuncum creek watershed, city of São Pedro-SP, based on the observed geological-geotechnical characteristics in the field and laboratory (soil geotechnical characterization and erodibility tests). It was verified that high susceptibility area to the erosion processes are mainl

10. Avaliação das alterações da rede de drenagem em sub-bacias e microbacias do alto e baixo rio Capivari (Louveira e Rafard/SP) / Evaluation of drainage network alterations in the high and low Capivari river microbasins and sub-basins (Louveira and Rafard/SP)
This work was proposed to evaluation the drainage networks time changes in the crystallines and sedimentaries hydrographic microbasins and sub basins, situated in the high and low Capivari river (Louveira and Rafard/SP). The methodological approach has consisted in the analysis of the morphometry, identification of physical environmental element and human ac

11. Assessment of changes in the drainage network of hydrographic sub-basins fo the medium course of the Capivari river basin (SP): scale 1:25.000 - subsidy for integrated planning / Avaliação das alterações na rede de drenagem de sub-bacias hidrográficas da porção média da bacia do rio Capivari (SP): escala 1:25.000 - subsídio para o planejamento integrado
This work used the drainage as a geoindicator to the changes that have taken place during 23 years (1972 to 1995) in the physical environment of three hydrographic sub-basins within the Monte Mor municipal boundaries, located in the medium course of the Capivari river hydrographic basin. The methodological approach comprises a complete characterization of th

12. Elaboração de carta de susceptibilidade à erosão das bacias dos rios Araraquara e Cubatão-SP, escala 1:50.000 / Elaboration of the erosion susceptibility map of the Araraquara and Cubatão river basins - SP, scale 1:50.000
In this present work many environmental attributes were identified, in order to create a soil erosion susceptibility chart (1:50.000 scale) for the Cubatão and Araraquara hydrographic basin, which in turn, are part of the greater Pardo river basin. These attributes were bedrock classification, unconsolidated materials, slope and land use. The soil erosion s
