1. Nonlinear Equilibrium and Stability Analysis of Axially Loaded Piles Under Bilateral Contact Constraints
AbstractThis paper presents a nonlinear stability analysis of piles under bilateral contact constraints imposed by a geological medium (soil or rock). To solve this contact problem, the paper proposes a general numerical methodology, based on the finite element method (FEM). In this context, a geometrically nonlinear beam-column element is used to model the

2. Triatoma jatai sp. nov. in the state of Tocantins, Brazil (Hemiptera: Reduviidae: Triatominae)
Triatoma jatai sp. nov. is the first new species of triatomine to be described in the state of Tocantins, in the northern region of Brazil. It was caught on rock outcrops in the wild environment and, more recently, invading homes. While T. jatai sp. nov. is morphologically similar to Triatoma costalimai, it is distinguished by its general colouring, differe

3. Biofertilizante de rochas mais matéria orgânica inoculada com bactéria diazotrófica na cana-de-açúcar.
Sugarcane (Saccharum spp.) Is currently considered one of the most important crops in the Brazilian social and economic. In Pernambuco, the sugar cane industry occupies an important agricultural area with high sugar and ethanol, generating many direct and indirect jobs. For increased productivity becomes necessary the use of management technologies that fost

4. Rock mass characterization of Morro Grande PCH using the RMR system / Compartimentação de maciços rochosos para projetos básicos de PCH´s usando o sistema RMR: aplicação no projeto básico da PCH Morro Grande - RS
The opening of the electric production sector in Brazil causes an increase amount of Small Hydroelectric Power Station - PCHs - project. The necessaries geological-geotechnical studies for this kind of construction had to be adapted to this new sector necessity, without quality losses. This research aim was the improvement of the geological-geotechnical stud

5. APLICATIONS OF PROBABILITY AND STATISTICS IN GEOTECHNICAL ANALYSES / APLICAÇÕES DE PROBABILIDADE E ESTATÍSTICA EM ANÁLISES GEOTÉCNICAS
In geotechnical analyses, forecasts of safety factors or deformations are developed on the basis of deterministics methods, that admit as fixed and known the parameters of the soil or the rock. However, such forecasts are affected by uncertainties proceeding from the reproduction impossibility of the field conditions in laboratory, of the disturbance of the

6. The application of rock mechanics to the analysis of rock foundations of concrete dams / Aplicação da mecânica de fratura à análise de fundações de barragens de concreto fundadas em rocha
O presente trabalho de pesquisa está relacionado à análise do progresso do fraturamento na zona tracionada de fundações rochosas de barragens de concreto e suas conseqüências nas avaliações de estabilidade global. Tomou-se como exemplo a barragem de Porto Primavera de propriedade da CESP (Companhia Energética de São Paulo), situada entre os estado
