1. Numerical analysis of soft soil improved with stone column technique
Abstract The present research aims to do a numerical study on the behavior of a test embankment reinforced with stone column spacing of 1.85 m in a square grid with an average diameter of 1.0 m and 11.35 m length. The case study investigated the work in a steel company (ThyssenKrupp), located in Santa Cruz, western region of Rio de Janeiro - Brazil, where a

2. Study of the interaction of concrete walls with the foundation structure
Abstract This article presents a study of the factors that influence the mechanism of soil-structure interaction with a pilot building having concrete walls and their impact on their performance. To illustrate the studies carried out, a numerical modeling of a four-floor concrete wall pilot building was performed, subjected to vertical actions, supported by

3. Mammal tooth traces in a ferruginous cave in southeastern Brazil and their relevance to cave legal protection
Abstract: We describe the first occurrence of biogenic traces made by mammals within an iron formation cave located in the Serra da Ferrugem Ridge, in Southeastern Brazil. These bioerosions are tooth traces produced in boulders, walls and floor within the cave. The traces occur as sets of two or more grooves, which are highly variable in size. The grooves we

4. EVALUATION OF STABILITY CONDITIONS OF THE JARDIM GRAMACHO LANDFILL / AVALIAÇÃO DE CONDIÇÕES DE ESTABILIDADE DO ATERRO METROPOLITANO DE JARDIM GRAMACHO
O Aterro Metropolitano de Jardim Gramacho (AMG) é o local que recebe desde 1976 os resíduos sólidos gerados pelas atividades domésticas, além das comerciais e industriais da área metropolitana do Rio de Janeiro. Atualmente no AMG vem se desenvolvendo projetos de aterramento até o ano 2012, portanto, a estabilidade dos taludes do maciço cresce em impo

5. A boundary element analysis on the influence of Krc and e/d on the performance of cyclically loaded single pile in clay
The environment prevalent in oceans necessitates the piles supporting offshore structures to be designed against lateral cyclic loading initiated by wave action. Such quasi-static load reversal induces deterioration in the strength and stiffness of the soil-pile system, introducing progressive reduction in the bearing capacity associated with increased settl

6. Response of vertical pile group subjected to horizontal cyclic load in soft clay
The environment prevalent in ocean necessitates the piles supporting offshore structures to be designed against lateral cyclic loading initiated by wave action. Such quasi-static load reversal induces deterioration in the strength and stiffness of the soil-pile system introducing progressive reduction in the bearing capacity as well as the pile head displace

7. ESTUDO DE TRAFEGABILIDADE APLICADO A VEÍCULOS DE RODA EM TRANSPORTE E TRAÇÃO / TRAFFICABILITY STUDY APPLIED TO WHEELED VEHICLES IN TRANSPORT AND TRACTION
The ability of vehicles to traverse soft soils is an important aspect of their performance. The geological, climate and topography diversity originated, in Rio Grande do Sul, extensive areas of hydromorphic clay soils, as example, Planssoils and Gleissoils. When saturated of water, these soft soils present low loads support, difficult agricultural machinery

8. 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

9. Estudo do comportamento geotécnico do depósito de argila mole da grande Porto Alegre / A study of the geotechnical behaviour of a soft clay deposit in the Porto Alegre metropolitan area
O comportamento geotécnico de um depósito de argilas é estudado nesta pesquisa, a partir de um extenso programa de ensaios de campo e de laboratório. Os estudos são concentrados em um campo experimental localizado na CEASA, na cidade de Porto Alegre. Outros locais foram também investigados, na área do Aeroporto Internacional Salgado Filho e na Estrada

10. Use of microbial reactors contaning immobilized cells on the treatment of the wastewater of a beverage industry. / Utilização de reatores microbianos com celulas imobilizadas no tratamento de efluente de uma industria de bebidas.
The present study the treatment of the waste waters of a beer and soft drink industry by an aerobic biological system was evaluated. The removal of the organic load by means of the quantification of the biochemical oxygen demand (BOD), chemical oxygen demand (COD), total ammoniacal nitrogen, turbidity, sedimented solids (SS), phosphorus (P), conductivity and

11. Poliuretanos e nanocompósitos biodegradáveis derivados de dispersões aquosas projetados para aplicações biomédicas
Waterborne polyurethane (PUDs) with potential for application as biomaterial were synthesized. Polypropyleneglycol (PPG) and/or polycaprolactonediol (PCL) were used as soft segment. The hard segment was formed by extending isophorone diisocyanate (IPDI) with hydrazine (HZ) producing poly (urethaneurea) s. PUDs were reinforced with Na+-montmorillonite (Na+-MM

12. CARACTERÍSTICAS DE COMPRESSIBILIDADE DE UMA ARGILA MOLE DA ZONA INDUSTRIAL DE SANTA CRUZ, RIO DE JANEIRO / COMPRESSIBILITY CHARACTERISTICS OF A SOFT CLAY FROM THE SANTA CRUZ INDUSTRIAL ZONE, RIO DE JANEIRO
A large research work comprising extensive field and laboratory investigations on a soft clay deposit located in the Industrial Zone of Santa Cruz, Rio de Janeiro, RJ, is being developed at PUC-Rio since 2005. Occurrences of settlement of structures built in this region have been reported since the end of the decade of 1970. This work presents results of lab
