A research on a specific type of unstiffened extended end-plate joint used to connect I-shaped beams to concrete-filled rectangular hollow section columns is presented in this paper. The main idea is to use long bolts throughout the column to connect the beam end-plates, so: (1) avoiding intermediate connecting elements (e.g. a reverse U channel) or special bolts (e.g. blind bolts) that are sometimes used in practice; (2) improving the resistance and stiffness of the joint to be used in seismic resistant frames. Firstly, a test program has been performed within a RFCS European project entitled HSS-SERF “High Strength Steel in Seismic Resistant Building Frames”, 2009-2013. In the test program, specimens subjected to significant bending moments (and shear) or to shear only have been defined. Then, analytical models based on the component approach and aimed at predicting the joint response have been proposed; their validity is demonstrated through comparisons with the test results. Finally, the requirements of EN-1998-1-1 related to full strength resistance for the proposed joint configuration are discussed, accounting for the actual position of plastic hinges and the possible individual over-strength factors for each component.

Anorexia nervosa is a complex pathology that regularly leads clinicians to a therapeutic impasse. The origin of this disorder is multifactorial. It occurs most often in adolescence and affects mainly women. Paradoxically, hunger is present but dissociated from adequate food function. Somatic and psychological impact can be particularly heavy. The treatment is difficult and requires a multidisciplinary care. An eclectic and integrative approach, moving away from rigid therapeutic methods and integrating the plurality of techniques, seems to be particularly recommended to increase the chances of therapeutic success. This article summarizes the various theoretical models of anorexia nervosa and its modalities of treatment. [less ▲]

As one of the results of an ambitious project, this handbook provides a well-structured directory of globally available software tools in the area of Integrated Computational Materials Engineering (ICME). The compilation covers models, software tools, and numerical methods allowing describing electronic, atomistic, and mesoscopic phenomena, which in their combination determine the microstructure and the properties of materials. It reaches out to simulations of component manufacture comprising primary shaping, forming, joining, coating, heat treatment, and machining processes. Models and tools addressing the in-service behavior like fatigue, corrosion, and eventually recycling complete the compilation. An introductory overview is provided for each of these different modelling areas highlighting the relevant phenomena and also discussing the current state for the different simulation approaches. A must-have for researchers, application engineers, and simulation software providers seeking a holistic overview about the current state of the art in a huge variety of modelling topics. This handbook equally serves as a reference manual for academic and commercial software developers and providers, for industrial users of simulation software, and for decision makers seeking to optimize their production by simulations. In view of its sound introductions into the different fields of materials physics, materials chemistry, materials engineering and materials processing it also serves as a tutorial for students in the emerging discipline of ICME, which requires a broad view on things and at least a basic education in adjacent fields.

Background : The aims of this study were to evaluate the effect of a single PRP injection followed by a standardized reeducation protocol among patients suffering from different tendinopathies, but otherwise healthy, and to determine the biomarkers that constitute good prognosis factors, if any. Methods : 48 patients suffering from different tendinopathies and refractory to conventional physiotherapy were treated with a single PRP injection. Prior to the injection, a blood sample was drawn and some biological parameters (glycemia, cholesterolemia,...) were measured. A pain assessment was then made using a Visual Analog Scale of pain (VAS) and a pressure algometer. The same assessment was carried out after 6 weeks and 12 weeks when possible. Results : There is an overall significant improvement in VAS score at the end of the 12 weeks follow- up. However, no correlation was found between the evolution of the clinical scores and the biological parameters measured. Conclusion: A PRP injection followed by a program of eccentric rehabilitation positively affects the algo-functional scores of patients with tendinopathies who were refractory to conventional physio- therapy, whatever the initial values of the measuured biological parameters.

Cette publication collective sur la notion de médiation est issue du constat suivant : dans le champ théorique comme dans le champ des pratiques, la médiation s’est aujourd’hui imposée, soit comme outil d’analyse des processus de communication, soit comme outil apte à soigner/traiter/améliorer les relations entre pairs, ou entre individus et institutions. Or la médiation reste un concept « instable », aussi bien dans la théorie, où elle est investie de toutes parts, que dans les pratiques, où elle ne répond pas à un référent unique. Ce recours aux pratiques et à la notion de médiation dans tous les domaines de la vie sociale , et ce alors même que cette notion n’est pas fondée, doit être interrogé comme tel dans un cadre scientifique et politique . Par l’examen croisé des usages de la notion dans différents champs de recherche et de ses usages dans des pratiques dites « de médiation », l’ouvrage entend présenter une approche critique et problématisée de la notion de médiation. A partir d’un corpus, d’enquêtes ou d’analyses de processus de médiation, les différents chapitres de l’ouvrage examinent les enjeux (scientifiques, théoriques, politiques ou idéologiques) auxquels l’usage du terme a répondu et répond aujourd’hui dans différents champs de recherches (sociologie, sciences de la communication, traduction, anthropologie) et de pratiques (médiation animale, scolaire, culturelle).

This 2016 Belgium Report Card on Physical Activity for Children and Youth is the first systematic evaluation of physical activity (PA) behaviors, related health behaviors, health outcomes, and influences thereon, using the Active Healthy Kids Canada grading framework. A research working group consisting of PA experts from both Flanders and Wallonia collaborated to determine the indicators to be graded, data sources to be used, and factors to be taken into account during the grading process. Grades were finalized after consensus was reached among the research working group and 2 stakeholder groups consisting of academic and policy experts in the fields of PA, sedentary behavior, and dietary behavior. Eleven indicators were selected and assigned the following grades: Overall PA (F+), Organized Sport Participation (C-), Active Play (C+), Active Transportation (C-), Sedentary Behaviors (D-), School (B-), Government Strategies and Investment (C+), and Weight Status (D). Incomplete grades were assigned to Family and Peers, Community and the Built Environment, and Dietary Behaviors due to a lack of nationally representative data. In conclusion, despite moderately positive social and environmental influences, PA levels of Belgian children and youth are low while levels of sedentary behaviors are high. [less ▲]

Le chêne rouge d’Amérique (Quercus rubra L.) est un arbre originaire d’Amérique du Nord et introduit en Europe à partir de la fin du XVIIème siècle pour l’ornementation et le commerce du bois. Le but de cette thèse est de comprendre les mécanismes écologiques et évolutifs qui contribuent à la dynamique et au succès de l’introduction de Q. rubra en Europe. Nous avons montré que cette espèce naturalisée et plantée dans certains pays européens parvient aisément à se développer de façon naturelle dans les forêts de feuillus et de conifères. La dispersion de ses glands est notamment rendue possible par des animaux fouisseurs-disperseurs, tels que les écureuils et les mulots, qui cependant préfèrent les glands du chêne natif Q. robur. Lors de l’introduction d’une espèce dans un nouvel environnement, des processus évolutifs sont susceptibles de se produire et d’engendrer des modifications phénotypiques et génétiques au sein des populations introduites. Une analyse comparative de la structure et de la diversité génétique des populations natives et introduites de Q. rubra a démontré que seulement deux des trois groupes génétiques de l’aire américaine sont actuellement présents en Europe. Aucun goulot d’étranglement fort n’a été détecté lors de l’introduction des populations en Europe laissant supposer que des introductions multiples ont pu maintenir la diversité génétique dans les populations introduites. Une analyse comparative des traits phénotypiques a permis de montrer que les populations introduites de Q. rubra présentent une croissance supérieure par rapport aux populations natives. Une différenciation génétique au sein des populations introduites est en cours pour le trait de débourrement foliaire suggérant une possible évolution adaptative rapide depuis l’introduction.

Fire brigades face a major threat when intervening in a building in fire: the possibility of structural collapse during the cooling phase of the fire, or soon thereafter. Currently this threat is amplified by the fact that the behaviour of structures after the time of peak gas temperature is not well understood, and is not taken into account in the design. This work presents an analysis of the behaviour of different structural members under natural fires and develops a method to characterize their sensitivity to fire decay phases. Thermo-mechanical numerical simulations based on the non-linear finite element method are conducted using the parametric fire model of Eurocode to represent natural fires. Results show that, for all the studied members (column, beam) and materials (reinforced concrete, steel and timber), structural failure during or after the cooling phase of a fire is a possible event. The major factors that promote delayed structural failure are the thermal inertia and the constituting material of the member. A method, based on a new indicator, is proposed to quantify the propensity to delayed failure for structural members under natural fire. This work enhances the understanding of the structural behaviour under natural fires and has important implications for the safety of the fire brigades and people proceeding to a building inspection after a fire.
