1. Large strain consolidation analyses of fine tailings disposal in mining pits
Abstract Herein, three-dimensional analyses of large strain consolidation applied to tail ings disposal in mining pits is studied. The main goal is to estimate filling time and, ac cordingly, the capacity of the pit. Other useful results, such as dry density profiles and water pore pressure generation are also obtained. Two different slimes from the iron or

3. Análise da influência da condutividade hidráulica saturada dos solos nos escorregamentos rasos na bacia do rio Guaxinduba (SP) / Analysis of the influence of saturated hydraulic conductivity from soils in the shallow landslides in the Basin of the River Guaxinduba (SP)
The prediction of landslides-prone areas has as fundamental step researching controlling factors and failure mechanisms. Some of these properties, such as the physical and hydrological soil properties are crucial to the instability of slopes subject to intense rainfall events. One of these properties is the saturated hydraulic conductivity, whose behavior ca

4. INVESTIGATION ABOUT PORE PRESSURE PREDICTION METHODS IN SHALES AND A PROBABILISTIC APPROACH APPLICATION / INVESTIGAÇÃO SOBRE OS MÉTODOS DE PREVISÃO DE PRESSÃO DE POROS EM FOLHELHOS E UMA APLICAÇÃO DE UMA ABORDAGEM PROBABILÍSTICA
Nos últimos 45 anos foram publicados muitos artigos referentes à previsão da pressão de poros em folhelhos, como resultado da necessidade de otimizar o processo construtivo de poços de petróleo. Neste trabalho se apresenta um panorama dos métodos de previsão de pressão de poros existentes, com suas vantagens e desvantagens, com seus pontos fortes e

5. PROBABILISTIC PORE PRESSURE PREDICTION IN RESERVOIR ROCKS THROUGH COMPRESSIONAL AND SHEAR VELOCITIES / PREVISÃO PROBABILÍSTICA DE PRESSÃO DE POROS EM ROCHAS RESERVATÓRIO ATRAVÉS DE VELOCIDADES COMPRESSIONAIS E CISALHANTES
This work proposes a method for pore pressure prediction in reservoir rocks through compressional- and shear-velocity data (seismic attributes). In the method, the attributes are considered observations of a physic system, which behavior depends on a several not-observable parameters, where the pore pressure is only one of these parameters. To estimate the p

6. New Insights into the Mechanisms of Water-Stress-Induced Cavitation in Conifers
Cavitation resistance is a key parameter to understand tree drought tolerance but little is known about the mechanisms of air entry into xylem conduits. For conifers three mechanisms have been proposed: (1) a rupture of pit margo microfibrils, (2) a displacement of the pit torus from its normal sealing position over the pit aperture, and (3) a rupture of an
