Piano Key Weirs (PKW) are a new type of weir, showing very good flood release capacities as well as strong economic and structural benefits. However, lacks of understanding persist about the flow conditions on such structures. With the goal to fill some of these lacks, a combined experimental and numerical study has been undertaken at the Laboratory of Structures Hydraulics of the University of Liege. This paper presents the goals and the scientific strategy of this research. The first results of experiments being carried out on a large physical model of PKW are also depicted. These experiments lead to characterization of the flow behavior for low heads and enable to highlight the influence of the crest thickness and the outlet slope on the release capacity. [less ▲]

Steroid hormones act in brain and throughout the body to regulate a variety of functions, including development, reproduction, stress and behavior. Many of these effects of steroid hormones are mediated by their respective receptors, which are members of the steroid/nuclear receptor superfamily of transcriptional activators. A variety of studies in cell lines reveal that nuclear receptor coregulators are critical in modulating steroid receptor-dependent transcription. Thus, in addition to the availability of the hormone and the expression of its receptor, nuclear receptor coregulators are essential for efficient steroid-dependent transactivation of genes. This review will highlight the importance of nuclear receptor coregulators in modulating steroid-dependent gene expression in brain and the regulation of behavior. [less ▲]

Following the need for understanding and quantifying the effect of temperature on the response of a candidate host formation for radioactive waste disposal, finite element modelling of an in situ thermal experiment has been carried out. Based on a thermo-hydro-mechanical (THM) finite element approach including a consistent thermo-plastic constitutive model, it has been possible to reproduce the THM response of a clay formation submitted to in situ thermal loading. The simulated large-scale experiment, called ATLAS was designed in the underground research facility (HADES-URF) in Mol, Belgium. After an extensive literature analysis on the thermal, hydraulic and mechanical characteristics of Boom Clay, laboratory tests were simulated to calibrate model parameters. The results of the finite element modelling of the ATLAS experiment were compared with in situ measurements and revealed the necessity to account for flow diffusion in all three directions through a 2D axisymmetric analysis. Finally, those results were interpreted in the light of elasto-thermoplasticity, which emphasizes the significant role of thermo-plastic processes in the global THM response of the clay formation.

This paper summarizes the minimal workout of chronic lymphoproliferative disorders in a routine laboratory of haematology as recommended by a team of experienced laboratory supervisors in Belgium, taking into account the specific organisation of healthcare in Belgium, the innovations in the field of molecular analyses and related reimbursement. The starting point was essentially based upon clinical and/or haematological indications and it is emphasized that conclusions should be drawn in close dialogue with the clinician and experts in cytogenetics and histopathology. Reports made in the laboratory should be based upon an integration of cytomorphological, immunophenotypical and molecular data. These guidelines are not intended to be used as universal 'diagnostic pathways', but should be useful in developing local diagnostic pathways. It is well understood that this consensus, being valid anno 2009, may rapidly change with new technologies being introduced and new targets discovered. [less ▲]

Belgium and Canada are definitely two very different countries in terms of geography, demographics, history. Politically, however, they share similar fundamental features: two distinct linguistic communities (and the minority in each case is French-speaking) live together in a federal system which is animated by political conflicts. Thus, Belgium and Canada are two interesting cases of multinational federations and it seems to be possible and above all insightful to study each case in light of the other. In this introduction, we first expose the rationale behind the comparative dialogue which is at the heart of this collective endeavor. Then, we briefly present each contribution and how they fit in the overall structure of the book. [less ▲]

Guillain-Barré syndrome (GBS) is often triggered by a preceding bacterial or viral infection. Occasionally, it has been observed in association with acute hepatitis A, B and C, and three cases have been previously described in India in which GBS was associated with acute hepatitis E. A molecular mimicry mechanism is supposed to be involved in the pathogenesis of GBS triggered by infectious agents, although the nature of the shared epitopes has not been characterized in most instances, including that in the case of hepatotropic viruses. We report a case of GBS following acute hepatitis E in a European individual. The presence of antiganglioside GM2 antibodies in this patient suggested molecular mimicry involving ganglioside GM2 in the pathogenesis of GBS associated with hepatitis E. [less ▲]

The Clinical Guidelines Committee of the European Association for Cardio-Thoracic Surgery provides this professional view on resuscitation in cardiac arrest after cardiac surgery. This document was created using a multimodal methodology for evidence generation including the extrapolation of existing guidelines from the International Liaison Committee on Resuscitation where possible, our own structured literature reviews on issues particular to cardiac surgery, an international survey on resuscitation hosted by CTSNet and manikin simulations of potential protocols. This protocol differs from existing generic guidelines in a number of areas, the most import of which are the following: successful treatment of cardiac arrest after cardiac surgery is a multi-practitioner activity with six key roles that should be allocated and rehearsed on a regular basis; in ventricular fibrillation, three sequential attempts at defibrillation (where immediately available) should precede external cardiac massage; in asystole or extreme bradycardia, pacing (where immediately available) should precede external cardiac massage; where the above measures fail, and in pulseless electrical activity, early resternotomy is advocated; adrenaline should not be routinely given; protocols for excluding reversible airway and breathing complications and for safe emergency resternotomy are given. This guideline is subject to continuous informal review, and when new evidence becomes available. [less ▲]

Le projet EURECA a pour but d'assister la conservation, le développement et l'utilisation des races bovines locales, et ce en se basant sur l'étude de races locales dans 10 pays européens. Ce projet (d'une durée totale de 3 ans) est coordonné au niveau belge par le Faculté des Sciences Agronomiques de Gembloux. La première phase du projet, présentée dans cet article, a consisté à interroger des éleveurs et des parties prenantes à l'aide d'un formulaire standard, afin de comprendre comment s'intègre les races locales au niveau des différents intervenants. L'étude a porté sur la Pie Rouge Mixte (PRm) et la Blanc Bleu Mixte (BBm). [less ▲]
