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.

Europe has a Digital Agenda set until 2020 that encompasses several actions related to health as well as an e-Health Action Plan 2013-2018. Belgium has followed the same path and decided to write down its own e-Health Action Plan 2013-2018. The Belgian financial and political context is quite challenging. On the one hand, health budgets are constantly decreasing and, on the other hand, a 6th State Reform is changing the political organisation, including the health system. The Action Plan is a political document negotiated by the government, insurances, care providers and service user groups in order to develop or integrate existing e-Health initiatives designed to increase financial effectiveness and quality of health care. Since it is conceived as an adequate response to the financial and quality of care challenges, health data sharing is included in that political agenda as a cornerstone of the evolution of the health system. This paper first reports negotiations involved in the making-up of e-Health policies, with a particular focus on policy instruments (Lascoumes & Le Galès, 2005; Halpern, Lascoumes & Le Galès, 2014). Then, by combining public action approaches to policy instruments with the strategic approach to collective action, such as defined by Crozier and Friedberg (1977), this paper analyses the implementation of e-health policies. In that respect, it particularly stresses the development of new organisation and instruments of work by health care providers, especially general practitioners. It focuses on the implementation of the e-Health platform. That initiative was launched in 2008 with the intent of integrating local health networks that developed separately due to the sharing of decision-making power between the federal, regional and community levels of the Belgian State. It had been opposed by medical doctors’ union, which argued that the management of health data registration and communication systems by the state threatened professional obligations as medical confidentiality. In spite of those oppositions between public health authorities and the representatives of the medical profession, general practitioners were required to use digital instruments to share medical data with their professional colleagues and other actors involved in health care delivery. Thus, this paper finally raises the question of the impact of e-Health policies decided by the government on members of the medical profession requested to put them into practice. More specifically, it will wonder about the concrete changes it implies in the doctor-patient relationship specific to the practice of medicine. Key concepts borrowed from sociological approaches to profession, for instance Freidson (1984), Bucher & Strauss (1992) Abbott (2005), will be used in examining that question. On the whole, this paper proposes a comprehensive and multi-level approach to the analysis of the development and implementation of e-Health policies. Methodologically, it is based on detailed analysis of professional, organisational and policy documents as well as 30 semi-structured interviews with representatives of federal and regional institutions, GPs or medical doctor trade union, e-Health experts and GPs of the Province of Liège.

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.

Genomic medicine is currently an expanding field. Based on the complete sequencing of the human genome, recent innovations promote the development of new protocols of diagnostic and treatments against hereditary genetic diseases. Thereby, they create opportunities which can disrupt the relationships between involved actors, such as patients and their relatives, concerned organisations, medical experts, as well as genomics specialists and health policy managers. This presentation exposes the baseline questions of a research project interested in some Belgian patients’ organisations’ involvement in issues related to genetic diseases within this current context, especially in the construction of the so-called scientific and medical evidence". It addresses its expansion to patients' experiential knowledge which is based on their lived experiences of health and disease." [less ▲]

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 ▲]
