The primary objective of this pilot study was to evaluate a new socket preservation technique involving the intentional expansion of the extraction socket buccal plate using a flapless internal corticotomy and biomaterials. A total of 11 patients requiring tooth extraction were enrolled in this study. The aim of this technique was to maintain or improve the hard and soft tissue contour of the ridge after tooth extraction. All surgical sites healed uneventfully. Significant alveolar bone dimension changes were observed in the coronal region of the ridge (-1.4 ± 0.9 mm); however, it was only slightly lower at the medium (-0.35 ± 0.7 mm) and apical levels (-0.3 ± 0.8 mm) (P > .05). The ridge dimensional changes were significantly higher in the buccal aspect than in the palatal aspect in all patients. Vertical bone resorption was not significant. Concerning the soft tissue contour, the horizontal distance between the preoperative and postoperative buccal profiles ranged from 0.94 to -2.88 mm. The proposed ridge preservation technique may help maintain the volume of the healed ridge but cannot completely prevent contour changes after tooth extraction. [less ▲]

Spatial autocorrelation expresses the dependence between values at neighbouring locations. Testing if the spatial autocorrelation is significant may confirm or deny the need to consider spatial analysis over the classical one. Indeed, the analysis of spatial data is only meaningful if the spatial components bring information. Several measures of spatial autocorrelation are defined in the literature. Moran’s index, Geary’s ratio and Getis-Ord statistic are the most used statistics. Tests based on these measures have been developed in the literature using asymptotic and permutation results. They are used in practice in many fields, for instance in geography, economics, biogeosciences, medicine, ... However, these tests should be cautiously applied because they are not robust. A single contaminated observation can significantly modify their results. This poster is composed of two parts. Firstly, the robustness of already available tools for measuring spatial autocorrelation will be analysed. Secondly, alternative methods will be proposed to robustly test the spatial autocorrelation.

We present a scanning Hall probe microscope operating in ambient conditions. One of the unique features of this microscope is the use of the same stepper motors for both sample positioning as well as scanning, which makes it possible to have a large scan range (few mm) in the x and y directions, with a scan resolution of 0.1 μm. Protocols have been implemented to enable scanning at different heights from the sample surface. The z range is 35 mm. Microstructured Hall probes of size 1-5 μm have been developed. A minimum probe-sample distance <2 μm has been obtained by the combination of new Hall probes and probe-sample distance regulation using a tuning fork based force detection technique. The system is also capable of recording local B(z) profiles. We discuss the application of the microscope for the study of micro-magnet arrays being developed for applications in micro-systems.

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 ▲]

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 ▲]
