1. Typological analysis of slidequakes emitted from landslides: experiments on an expander body pile and Sobradinho landslide (Brasilia, Brazil)
Abstract Reactivation of a landslide is usually accompanied by microseismic signals emitted from the deforming soil mass. The reproduction of similar signals in a physical model test conducted under control conditions can allow researchers to explore and test such complicated signals to improve the prediction of full-scale failure. The present study investig

2. Anticipating the response of the Brazilian giant earthworm (Rhinodrilus alatus) to climate change: implications for its traditional use
Abstract Our understanding of the impacts of ongoing global warming on terrestrial species has increased significantly during the last several years, but how climatic change has affected, and will affect, the distribution of earthworms remains largely unknown. We used climate niche modeling to model the current distribution of the giant earthworm Rhinodrilus

3. Energy balance partitioning and evapotranspiration from irrigated Muskmelon under Semi-Arid Conditions
ABSTRACT The Mossoró-Assu-Baraúna district, Rio Grande do Norte State (RN), is recognized by the intense production of horticulture, mainly muskmelon for export. However, this region is often devastated by intense droughts. Thus, the muskmelon production is predominantly under irrigated condition and, due to constant threat of water resources collapse on t

4. Static Limit Analysis of Reinforced Soil Structures by a Simple Finite Element and Second-Order Cone Programming
Abstract To discretize reinforced soil structures in plane strain and predict their collapse load, a simple three-node triangular finite element is formulated based on the static theorem of the limit analysis. The element satisfies the equilibrium equations and the mechanical boundary conditions in a weak sense. A modified Mohr-Coulomb yield surface is adopt

5. COMPORTAMENTO DE TALUDE DA MARGEM DO RIO SÃO FRANCISCO SUBMETIDO À TECNICA DE BIOENGENHARIA DE SOLOS. / BEHAVIOR OF THE SLOPE OF THE SÃO FRANCISCO RIVER SUBJECTED TO THE SOIL BIOENGINEERING TECHNIQUE.
The lower San Francisco river had changed their hidrossedimentological behavior by changes in river channel through the impoundment of water reservoirs for the implementation of large hydropower projects. These direct impact on the stability of river banks, demands actions to mitigate the erosion resulting from soil mass movements. Soil bioengineering, which

6. Micro-sítio como filtro para o estabelecimento de regenerantes arbóreos em áreas restauradas / Microsites as filters for tree species establishment under restoration plantings
The characteristics of the natural regeneration of restoration plantings understory express the main indicators of success of ecological restoration projects, in which the absence of regeneration indicates a bottleneck for the perpetuation of forest communities inserted into highly fragmented landscapes. Nevertheless, adverse conditions of the micro-site of

8. Colapsibilidade com sucção controlada de um solo coluvionar e laterítico de Campinas/SP / Collapsibility with controlled suction of a colluvial and lateritic soil from Campinas/SP
This study aims at investigating the collapsibility of coluvionar and lateritic soil by oedometer tests with controlled suction, performed in the laboratory, and by the interpretation of the soilimpregnated thin plates before and after the tests, so as to take into account the differences between natural and "after collapse" structures. The undisturbed soil

9. A rough terrain traction control technique for all-wheel-drive mobile robots
Traction control is a critical aspect of mobile robots that need to traverse rough terrain, avoiding excessive slip - which may cause the terrain to collapse locally and trap the robot wheels - and guaranteeing an adequate trajectory and speed control while reducing the power requirements. Traction control of all-wheel-drive robots in rough terrain was origi

10. Selection of biosurfactan/bioemulsifier-producing bacteria from hydrocarbon-contaminated soil
Petroleum-derived hydrocarbons are among the most persistent soil contaminants, and some hydrocarbon-degrading microorganisms can produce biosurfactants to increase bioavailability and degradation. The aim of this work was to identify biosurfactant-producing bacterial strains isolated from hydrocarbon-contaminated sites, and to evaluate their biosurfactant p

Floods are natural events but they correspond to a third of all natural disasters worldwide (Smith, 2004) and their consequences can be aggravated by human activities, such as urbanization, lack of urban planning and occupation of risk areas. These facts occur on most urban centers in Brazil, including the city of Campinas (SP). The research aimed to analyze

12. Behavior of concrete "mega" piles, installed in collapsible soil / Comportamento de estacas Mega de concreto, implantadas em solo colapsivel
There are very common cases of works that have problems due to the collapse of foundations and soil, and in the most of the works, the solution applied is the underpinning with Mega piles of concrete that, despite the wide use, there are few studies on this type of foundation. With the aim of add parameters to the technical means about this type of foundatio
