Operators have deployed Multiprotocol Label Switching (MPLS) in the Internet for over a decade. However, its impact on Internet topology measurements is not well known, and it is possible for some MPLS configurations to lead to false router-level links in maps derived from traceroute data. In this paper, we introduce a measurement-based classification of MPLS tunnels, identifying tunnels where IP hops are revealed but not explicitly tagged as label switching routers, as well as tunnels that obscure the underlying path. Using a large-scale dataset we collected, we show that paths frequently cross MPLS tunnels in today's Internet: in our data, at least 30% of the paths we tested traverse an MPLS tunnel. We also propose and evaluate several methods to reveal MPLS tunnels that are not explicitly flagged as such: we discover that their fraction is significant (up to half the explicit tunnel quantity) but most of them do not obscure IP-level topology discovery.

The many recently published data on vitamin D have raised much interest in the medical community. One of the consequences has been a great increase in the prescription of vitamin D concentration measurements in clinical practice. It must be reminded that only the measurement of 25-hydroxyvitamin D (25(OH)D) concentration is indicated to evaluate vitamin D status. Furthermore, since vitamin D insuffi ciency is so common, since treatment is inexpensive and has a large safety margin, and since we already have much data suggesting that besides its classic effects on bone and mineral metabolism, vitamin D may potentially be helpful for the prevention/management of several diseases, perhaps should it be prescribed to everyone without prior testing? In our opinion, there are however groups of patients in whom estimation of vitamin D status is legitimate and may be recommended. This includes patients in whom a “ reasonably ” evidence-based target concentration (i.e., based on randomized clinical trials when possible) should be achieved and/or maintained such as patients with rickets/osteomalacia, osteoporosis, chronic kidney disease and kidney transplant recipients, malabsorption, primary hyperparathyroidism, granulomatous disease, and those receiving treatments potentially inducing bone loss. Other patients in whom vitamin D concentration may be measured are those with symptoms compatible with a severe vitamin D defi ciency or excess persisting without explanation such as those with diffuse pain, or elderly individuals who fall, or those receiving treatments which modify vitamin D metabolism such as some anti-convulsants. Measurement of Vitamin D concentrations should also be part of any exploration of calcium/phosphorus metabolism which includes measurement of serum calcium, phosphate and PTH. [less ▲]

Introduction: Tendinopathies, especially jumper’s knee, often remain rebel to conservative treatments. Several experimental studies have shown the healing properties of platelet and their growth factors. Researches have specifically demonstrated the platelets action as mediator and/or enhancer of tissue healing. The aim of our study was to investigate the effect of 1 injection of PRP in patients suffering from chronic jumper’s knee. Our protocol was approved by Ethic Committee of University and University Hospital of Liège. Methods: Patients performed imaging (US and MRI) and functional assessments, and a clinical examination using an algometer, before treatment and 6 weeks after PRP treatment. They were also invited to answer to questionnaire relative to pain and functional status. PRP was obtained from autologous blood using an apheresis system (COM.TEC, Fresenius). The injection of 6mL of PRP was realised without local anaesthesia into the proximal insertion of the patellar tendon. A 48h rest-time was recommended after infiltration. Afterwards, a submaximal eccentric reeducation was initiated 1 week after infiltration 3 times a week during 5 weeks. In case of pain, anti-inflammatory drugs were prohibited and patient were encouraged to take class I or II painbrakers. Results: At this time, 10 patients with jumper’s knee were included in our study. Pre-injection tests revealed pain of the upper part of the patellar tendon just below the patella, associated with loss of function. Imaging exams confirmed diagnosis. Six weeks post-injection, the clinical status was improved in all patients, with a significant decrease of algo-functional scores. The pain reported during functional assessments was decreased (in particular for the eccentric actions), yet no significant improvement of physical performances was observed. We found no significant differences between imaging exams before and 6 weeks after PRP injection. Conclusion: One in situ injection of PRP clinically improved patients with jumper’s knee 6 weeks after treatment. All the 10 patients reported a decrease of pain during day-life and through physical activities. However nor functional performances neither imaging were improved. [less ▲]

Since a few decades, the Senegalese small-scale fishing knows important upheavals which mortgage its dynamism. The increase of fishermen's staff, the evolution of the techniques of fishing, the degradation of marine ecosystems are so many blocking factors that the fishing management policies have to consider to check on the decline of the halieutic resources and guarantee the durability of the activities for coastal populations in Senegal. In 2004, the Government proceeded to create five marine protected areas (MPA) throughout the littoral to bring an answer to the problem of management of fisheries. The MPA appear as a tool of preservation and development and fit into territories of fishing strongly suited by communities in presence. Among these, the community of the migrant fishermen the Guet- ndariens, of the north Senegalese quotation, sees their spaces being transformed in front of this new policy of the Government. But also in front of strategies of control which try to set up the autochthonous populations to counter in their strong activity of fishing. So, we attend a competition pushed on the resource on the background of latent conflicts. But also a transformation of the strategies of the various actors in their perceptions of the space of the identical, historic and functional point of view [less ▲]

This paper presents an overview of the case law of the ECJ in relation to Regulation 44/2001. The focus is on cases decided by the ECJ, with a few reference made to court practice in Belgium. Cases are presented and discussed in relation to the various provisions of the Regulation to which they relate. For each case, an abstract is included, followed by (critical) comments. This overview appeared in a book presenting the main European regulations dealing with European procedural law (jurisdiction of courts, recognition and enforcement of foreign judgments). The book is part of a series edited by Prof. Georges de Leval (University of Liège), which collects court practice in relation to procedural law. [less ▲]

Pourquoi, au sein de sociétés démocratiques et de systèmes éducatifs ouverts, les jeunes de milieux populaires se retrouvent-ils souvent dans des filières et des formes d’enseignement peu valorisées dans la hiérarchie scolaire ? À partir d’une enquête qualitative de longue durée, cet ouvrage propose une relecture de la sociologie de l’éducation en confrontant les interprétations de l’orientation à un corpus empirique inédit. Une immersion prolongée dans les familles, les lieux de sociabilité d’élèves de l’enseignement professionnel, les séances d’orientation et les conseils de classe donne à ce livre l’épaisseur ethnographique nécessaire pour saisir les réalités scolaires. Au-delà des processus de relégation, cet ouvrage donne à voir les pratiques et les représentations des acteurs qui façonnent les trajectoires. En choisissant une région postindustrielle comme principal terrain d’enquête, c’est aussi la question de la transformation des classes sociales qui est posée. Les cultures de classe demeurent-elles le facteur clé pour expliquer les mécanismes de l’orientation ? L’analyse du processus d’orientation vers l’enseignement de type professionnel nous plonge ainsi dans un débat plus vaste sur la reproduction culturelle et le changement social. [less ▲]

La compréhension des procédés technologiques et industriels dans les secteurs (bio)pharmaceutiques, biotechnologiques, agroalimentaires et environnementaux doit permettre de se conformer aux lignes de conduites initiées par la FDA ou d'autres organismes de contrôles. Notamment, le document ICH Q8 introduit les notions de "Process Analytical Technology", de "Quality by Design" et de "Design Space", ayant attraits à la qualité des procédés industriels, des procédés d'analyse ainsi qu'à la qualité des produits finis. Cependant, si les lignes de conduites pour ces exigences sont expliquées, aucune méthodologie pour les atteindre n'est donnée. Or, un nombre considérable de nouvelles entités chimiques sont synthétisées par les laboratoires pharmaceutiques, biotechnologiques ou agroalimentaires. Les producteurs de matières premières et/ou d’excipients (secteur chimique) ont également besoin de disposer rapidement de méthodes analytiques de contrôle qui leur permettront de s’assurer de la qualité de leurs produits. On comprend aisément la nécessité pour ces secteurs de disposer rapidement de résultats fiables puisque les activités de recherches mais aussi des investissements, souvent importants, sont orientés ou stoppés sur base de données chiffrées, produits par les méthodes analytiques. La production de résultats fiables et la démonstration de cette fiabilité sont donc économiquement fondamentales. Ce projet vise la mise au point de stratégies et de modèles génériques de développement automatisé de nouvelles méthodes analytiques séparatives, en se basant sur la modélisation des temps de rétention, la planification expérimentale, et le concept de Design Space. L’objectif connexe est d’appliquer cette méthodologie à l’optimisation de n’importe quel procédé. Le fait de pouvoir disposer d’une méthodologie de mise au point automatique de méthodes analytiques ou de tous procédés analytiques aura un impact significatif. Cette nouvelle technologie permettra de réduire de façon drastique le temps d’optimisation des méthodes et procédés, permettant une production plus efficiente de produits (pharmaceutique, cosmétique, agro-alimentaire ou biotechnologique) répondant aux spécifications du client.
