4. Strut-and-tie models for linear and nonlinear behavior of concrete based on topological evolutionary structure optimization (ESO)
Resumo A busca por sistemas resistentes representativos para estrutura de concreto requer profundo conhecimento sobre seu comportamento mecânico. Os modelos de bielas e tirantes são procedimentos clássicos utilizados no dimensionamento do concreto armado onde existem concentrações de tensão, as chamadas regiões descontínuas da estrutura. No entanto,

5. Micro-mechanical numerical analyses on the effect of stress state on ductile damage under dynamic loading conditions
Abstract The paper deals with the effect of stress state on the dynamic damage behavior of ductile materials. The rate- and temperature-dependent continuum damage model has been enhanced to take into account the influence of the stress triaxiality and the Lode parameter on damage condition and on rate equations of damage strains. Different branches of these

6. Actualidad de la renovación pedagógica en la Comunidad de Madrid: un estudio a través de centros escolares representativos
Abstract The history of Spanish pedagogical renewal harbors an extensive and plural activity that confirms the search for a school configured not only for academic purposes, but also understood as the motor of personal, cultural and social transformation. There are numerous educational centers throughout Spanish history that bring evidence to this search, bu

7. Yield Surfaces of Material Composed of Porous and Heterogeneous Microstructures Considering Phase Debonding
Abstract This work deals with numerical simulation of the mechanical behavior of materials composed of heterogeneous ductile microstructures using a multi-scale approach considering plasticity processes and phase debonding. Due to few studies about yield surfaces of metal matrix composites (MMC) with weak interfaces presented in the literature, the major goa

8. SUSTAINABILITY IN INFORMATION TECHNOLOGY: AN ANALYSIS OF THE ASPECTS CONSIDERED IN THE MODEL COBIT
ABSTRACT Parallel to the development of technology in its different fronts and particularly about the various applications of Information Technology (IT), another trend that has been consolidated in organizations is the search for sustainability. There are initiatives such as Green IT, Sustainable IT, and Green software that combine these two elements (IT an

9. 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

10. Laminated Composites Buckling Analysis Using Lamination Parameters, Neural Networks and Support Vector Regression
AbstractThis work presents a metamodel strategy to approximate the buckling load response of laminated composite plates. In order to obtain representative data for training the metamodel, some laminates with different stacking sequences are generated using the Latin hypercube sampling plan. These stacking sequences are converted into lamination parameters so

11. El campo de las ciencias y la educación superior entre el monopolio del inglés y el plurilingüismo: elementos para una política del lenguaje en América Latina
The field of science and higher education presents a strategic space that clearly reflects some of the problems which spring from the globalisation of English as today's only hyper-central language: from a model of limited plurilingualism based on German, English, and French in the beginning of the XXth century, the field has moved to an almost absolute pred

12. Elementos traço em material particulado atmosférico de uma região agroindustrial do sudeste do Brasil
Trace element concentrations were measured in atmospheric particulate matter collected in 2009 and 2010, in a Brazilian region influenced by pre-harvest burning of sugar cane crops. For coarse particles, high concentrations of Al, Fe, K and Ca suggested that re-suspended soil dust was the main source of aerosol trace elements, subsequently confirmed by XRD a
