The proper planning of investigations before carrying out repair works is important if optimum use is to be made of the test data. A major step needs to be taken from knowing, for example, that chloride is present in the concrete, to select the best methods for repair. Engineers require guidance on both the techniques available for the condition assessment of structures and the methods for data interpretation. Two major stages are usually recommended for such an operation: the first stage is based on a rapid-scan visual assessment, often including limited sampling in areas obviously damaged, from which areas can be selected for more detailed investigations. The second stage contains a detailed diagnostic survey that relies on destructive and non destructive testing techniques. Non destructive techniques are more and more utilized not only for the evaluation of the concrete strength but also for the detection of cracks and delaminations. Moreover, the interest for techniques able to evaluate concrete permeability is rising, due to the importance of this factor for durability evaluation. The paper will discuss the assessment of concrete structures and describe the main destructive and non destructive techniques with regard to specific pathologies. [less ▲]

Today, state-of-the-art simulation packages in flexible multibody dynamics allow the high-fidelity analysis of industrial mechanisms and machines in many application fields including robotics, automotive systems, aeronautics, deployable structures or wind turbines. The dynamic response of a given system can thus be evaluated in the time-domain for given load cases and given initial values. However, in many practical cases, the engineer does not have a precise knowledge of the mechanical design, the loading conditions and the initial state. This situation occurs for example in structural optimization, optimal control, experimental identification and health monitoring problems. The complexity of simulation codes and the computational cost of high-fidelity models are still important obstacles for the development of efficient resolution methods for these inverse problems. A current challenge is thus to elaborate simplified and more efficient modelling strategies in flexible multibody dynamics in order to enable the development of inverse analysis methods. The talk is divided into three parts. The first part provides an overview of available simulation techniques for flexible mechanisms with a particular emphasis on finite element-based approaches and time integration methods. Some illustrations are presented in the fields of deployable structures, vehicle dynamics and wind turbines. In the second part, optimization problems in flexible multibody dynamics are addressed and solved using gradient-based methods. Efficient methods for sensitivity analysis are discussed and special problems are treated such as the structural optimization of mechanical components or the numerical solution of inverse dynamics problems. The third part discusses a recently-developed Lie group approach which allows the formulation of the equations of motion of a multibody system in a parameterization-free setting. Based on this general formalism, which is characterized by an increased modularity and a reduced complexity, a large variety of Lie group solvers are foreseen not only for time integration but also for model reduction, sensitivity analysis and optimization.

We explore the large-scale behavior of nucleotide compositional strand asymmetries along hum chromosomes. As we observe for 7 of 9 origins of replication experimentally identified so far, the (TA GC) skew displays rather sharp upward jumps, with a linear decreasing profile in between two successi jumps. We present a model of replication with well positioned replication origins and random terminatio that accounts for the observed characteristic serrated skew profiles. We succeed in identifying 287 pairs putative adjacent replication origins with an origin spacing 1­2 Mbp that are likely to correspond replication foci observed in interphase nuclei and recognized as stable structures that persist througho subsequent cell generations.

The complete understanding of the morphological differentiation of streptomycetes is an ambitious challenge as diverse sensors and pathways sensitive to various environmental stimuli control the process. Germination occupies a particular position in the life cycle as the good achievement of the process depends on events occurring both during the preceding sporulation and during germination per se. The cyclic AMP receptor protein (crp) null mutant of Streptomyces coelicolor, affected in both sporulation and germination, was therefore presented as a privileged candidate to highlight new proteins involved in the shift from dormant to germinating spores. Our multidisciplinary approach-combining in vivo data, the analysis of spores morphological properties, and a proteome study-has shown that Crp is a central regulatory protein of the life cycle in S. coelicolor; and has identified spores proteins with statistically significant increased or decreased expression that should be listed as priority targets for further investigations on proteins that trigger both ends of the life cycle.

Strychnos henningsii GILG is used in African traditional medicine for the treatment of various ailments, including rheumatism, gastrointestinal complaints, malaria and snake bites. Different preliminary pharmacological experiments are described. The results show that some of the reported folk medicinal applications of S. henningsii can be at least partially explained by the presence of retuline-like alkaloids, whose use could lead to new antinociceptive (antiinflammatory and analgesic) and antispasmodic drugs.

In recent years, the European Union and the Common Agricultural Policy have made considerable changes in policy related to the dairy sector. After two successive dairy crises in 2009 and 2012, the dairy sector in Belgium was weakened considerably. The Belgian fair-trade milk enterprise, Fairebel, was created by dairy farmers a few months after the 2009 European milk crisis, seeking to develop their alternative, supported, owned by and for traditional dairy farmers. This case study brings into question ‘fair trade’ as a concept and practice in terms of trade between enterprises in Europe, and the surprise effects of interaction when analysed at both European and regional scales. The study concludes that the best innovation processes are not necessarily radical, and that tinkering – or bricolage – is the path taken by many innovations. [less ▲]

In this short article I examine some theatrical performances which might be placed under the umbrella of ‘provocation’, and which are understood here as moments of political activism. First of all, I briefly evoke some actions produced by the students’ protest movement at the end of the Sixties in Berlin. Then, I consider the problems which threaten every political provocation and which appear as challenges to the political theatrical creation; namely overbidding and inflation. Finally, I evoke possible answers to these challenges, especially through several performances of the duo of political activists known as the Yes Men, and those of the Italian “clown” Leo Bassi. Their happenings or performances, at least partly, transcend the limitations which can turn a political provocation into an ineffective, commercialized and bankable product. [less ▲]
