Through dialogues between partners, a river contract intends to develop and restore the multiple functions and uses of water in answer to the needs of a community of users. Under this scheme, both government and private-sector players commit themselves by means of a contract to implement a consensus action programme to restore the river and its drainage basin’s water resources. Information and awareness campaigns are added to concrete actions of waterway development and different sorts of work connected to water. The river committee is a place for democratic speech where the familiar rubs shoulders with the institutional, where citizens meet operators, where the life forces of society are finally brought together to take charge of their river’s future and their relationship with the river. In this way, a joint project has been bringing together Belgian and French protagonists since 1999, trough the Interreg II and Interreg III operational programmes. They work now together in a joint management of the river and its tributaries, this time on the scale of the entire Semois-Semoy hydrographical subdrainage basin. This article describe the concept and the methodology of this concrete transboundary collaboration, the results and the perspectives. [less ▲]

Mutations in two genes encoding cell cycle regulatory proteins have been shown to cause familial cutaneous malignant melanoma (CMM). About 20% of melanoma-prone families bear a point mutation in the CDKN2A locus at 9p21, which encodes two unrelated proteins, p16(INK4a) and p14(ARF). Rare mutations in CDK4 have also been linked to the disease. Although the CDKN2A gene has been shown to be the major melanoma predisposing gene, there remains a significant proportion of melanoma kindreds linked to 9p21 in which germline mutations of CDKN2A have not been identified through direct exon sequencing. The purpose of this study was to assess the contribution of large rearrangements in CDKN2A to the disease in melanoma-prone families using multiplex ligation-dependent probe amplification. We examined 214 patients from independent pedigrees with at least two CMM cases. All had been tested for CDKN2A and CDK4 point mutation, and 47 were found positive. Among the remaining 167 negative patients, one carried a novel genomic deletion of CDKN2A exon 2. Overall, genomic deletions represented 2.1% of total mutations in this series (1 of 48), confirming that they explain a very small proportion of CMM susceptibility. In addition, we excluded a new gene on 9p21, KLHL9, as being a major CMM gene. [less ▲]

Le modèle de Karasek (1979) est l’un des modèles le plus utilisé dans les recherches sur le lien travail-famille et sur le stress professionnel. Parmi les variables qu’il inclut, figurent le support social du supérieur et des collègues. À notre connaissance, peu d’études ont essayé d’analyser le lien entre l’interférence travail-famille, le stress négatif et d’autres sources de support social tel que le support perçu de l’organisation. Or, en accord avec la méta-analyse de Rhoades & Eisenberger en 2002, nous faisons l’hypothèse que le support organisationnel perçu joue un rôle central dans le lien entre les caractéristiques du travail, l’interférence négative travail-famille et le stress négatif qui en découle. Notre étude s’est réalisée dans un hôpital belge auprès de 266 membres du personnel soignant. Le questionnaire utilisé comprend : le Job Content Questionnaire de Karasek; l’échelle de support organisationnel perçu de Eisenberger (1986), l’échelle d’interférence négative du travail sur la famille (SWING, Geurts, 2004) et le stress négatif (SPPN, Hansez et al., 2004). Il en résulte que le support organisationnel perçu joue un rôle central dans les relations entre certaines caractéristiques du travail, l’interférence négative travail-famille et le stress par le biais d’une double médiation. En outre, l’effet négatif des exigences de travail sur le support organisationnel perçu est modéré par la latitude de décision que les employés peuvent avoir dans leur travail. Les résultats suggèrent qu’introduire le support organisationnel perçu dans des modèles liés aux relations travail-famille enrichirait les deux courants de recherche envisagés dans cette étude. En outre, le type de modèle utilisé dans cette recherche pourrait aussi être appliqué à d’autres types de variables dépendantes (e.g. la performance au travail). [less ▲]

Ivabradine (Procoralan), a new If inhibitor which acts specifically and in a dose-dependent manner on the pacemaker activity of the sinoatrial node, is a pure heart rate lowering agent. It slows the diastolic depolarization slope of sinoatrial node cells and reduces heart rate at rest and during exercise. It has shown anti-ischaemic and anti-anginal activity at recommended doses of 5 and 7.5 mg bid in patients with stable angina. Ivabradine is as effective as atenolol and amlodipine to prevent or attenuate exercise-induced ischaemia in these patients. It is well tolerated, with transient visual symptoms being the main drug-related adverse event. These symptoms may be linked to the presence in the retina of ion channels similar to cardiac If channels and did not adversely affect the tolerability of the drug for most patients. In Belgium, ivabradine is currently reimbursed in patients with stable angina and normal sinus rhythm who do not tolerate beta-blockers and non-dihydropyridine calcium antagonists or in whom these treatments are contra-indicated.

En Belgique, le taux d’emploi des travailleurs âgés est un des plus faibles de toute l’Europe. Cela constitue un problème tant au niveau économique que social (Griffiths, 1997 ; Kilbom, 1999). Cette nouvelle problématique est le point de départ de recherches visant à identifier ce qui pousse les travailleurs à quitter précocement le lieu de travail. Se basant sur le modèle ‘Job Demands Resources (JDR) Model’ (e.g. Demerouti, Bakker, Nachreiner & Schaufeli, 2001; Schaufeli & Bakker, 2004), une étude a été conduite afin d’identifier les raisons de départ (Griffeth, Hom & Gaertner, 2000). Il s’agit également d’étudier le rôle du stress et de l’engagement dans l’explication de ces retraits précoces. Le but est de comparer un modèle d’explication du turnover pour trois classes d’âges ; les jeunes travailleurs, les travailleurs d’âge moyen et les travailleurs âgés. Un questionnaire a été développé afin d’identifier les raisons de départ des travailleurs. Quatre facteurs de départ sont considérés dans cette dimension trans-générationnelle. Deux d’entre eux concernent les ressources de travail, soit le manque de ressources, le manque de développement personnel, et les deux autres concernent les demandes du travail, soit la pression et les changements organisationnels. Une mesure du stress, de l’engagement et de l’intention de quitter a aussi été inclue. Au total, 11 entreprises belges ont participé à cette enquête, ce qui correspond à 1772 questionnaires. Les résultats montrent que le manque de développement personnel et les changements expliquent directement l’intention de quitter pour les jeunes et les travailleurs d’âge moyen. Par contre, le manque de ressources explique directement l’intention de quitter pour les travailleurs âgés. Le stress et l’engagement jouent un rôle important dans l’explication de l’intention de quitter pour les trois groupes d’âges. La pression et le manque de ressources expliquent le stress. Le manque de ressources, le manque de développement personnel et la pression ont un impact sur l’engagement. Les changements organisationnels n’expliquent pas le stress. Pour les travailleurs âgés, le manque de ressources n’affecte pas l’engagement. En conclusion, le manque de développement personnel et les changements organisationnels ont plus d’impact au début de la carrière et le manque de ressources est un problème qui concerne davantage les travailleurs âgés. L’état psychologique et l’évaluation des conditions de travail sont très importants pour toutes les classes d’âge dans la décision du retrait. [less ▲]

The time lag method is one of the most straightforward methods used to estimate transit times from experimental data and is therefore widely used. The transit time between two points is estimated from the analysis of time series taken at these two points that suggest the propagation of a signal from one point to the other. To account for the distortion of the signal during its propagation between the two points an optimum time lag can be estimated by the analysis of the cross-correlation of the two time series. This study clarifies the relation between the transit time estimated by the time lag method and the well-defined concept of the age of a water mass. It is shown, through simplified process models, that the time lag method systematically underestimates the true mean age. The error can be quantified by means of a dimensionless parameter which is the inverse of a Peclet number based on a characteristic length given by the ratio of the velocity of the flow to the frequency of the signal.

Fe/SiO2 catalysts have been prepared by two different sol-gel methods, cogelation and dissolution. The cogelation and dissolution preparative methods lead to xerogels with fundamentally different pore width distributions. The nature of the iron species obtained has been examined in detail by UN-visible and Mossbauer spectroscopy, and magnetic, transmission electron microscopy, and X-ray diffraction studies. There is no evidence for the presence of any ordered iron(III) oxides in the samples but all three contain two types of iron species, specifically paramagnetic high-spin iron(III) ions isolated in silica and iron(III) containing nanoparticles with a broad width distribution centered on 1.5 nm, nanoparticles that contain antiferromagnetically coupled clusters of a few ligated bridged iron(III) ions.

Economic reasoning is a distinctive feature of competition law. At first sight, it may appear as foreign to judges. A closer analysis, however, shows that there is no conflict of logic between economic and judicial reasoning. Some points of convergence between these modes of reasoning are underlined. In addition, it is submitted that obstacles to judicial acknowledgement of economic reasoning are purely relative. The proposed analysis then proceeds to investigate how economic reasoning may be incorporated into judicial methods. It is shown that this is achieved by way of ordinary mechanisms. Indeed judges may use economic analysis to determine the relevant facts and legal tests. It follows that judicial control over economic reasoning – including that of competition authorities – can be explained by a very general theory of judicial review, according to which the depth of judicial control over grounds of fact and law depends on the dynamics of litigants’ contentions.

AIMS: To critically review the available transcatheter aortic valve implantation techniques and their results, as well as propose recommendations for their use and development. METHODS AND RESULTS: A committee of experts including European Association of Cardio-Thoracic Surgery and European Society of Cardiology representatives met to reach a consensus based on the analysis of the available data obtained with transcatheter aortic valve implantation and their own experience. The evidence suggests that this technique is feasible and provides haemodynamic and clinical improvement for up to 2 years in patients with severe symptomatic aortic stenosis at high risk or with contraindications for surgery. Questions remain mainly concerning safety and long-term durability, which have to be assessed. Surgeons and cardiologists working as a team should select candidates, perform the procedure, and assess the results. Today, the use of this technique should be restricted to high-risk patients or those with contraindications for surgery. However, this may be extended to lower risk patients if the initial promise holds to be true after careful evaluation. CONCLUSION: Transcatheter aortic valve implantation is a promising technique, which may offer an alternative to conventional surgery for high-risk patients with aortic stenosis. Today, careful evaluation is needed to avoid the risk of uncontrolled diffusion. [less ▲]

The Sahara largely contributes to the global injection of mineral dust into the northern hemisphere. Since the onset of the drought in the Sahel and the environmental degradation in the arid and semi-arid belts surrounding the Sahara, dust storms frequency and intensity has dramatically increased. It is now irrefutable that air pollution caused by large amounts of respiratory particulates or Particulate Matter less than 10 µm in aerodynamic diameter (PM10) has numerous undesired consequences on human health. Air quality degradation far away from the African continent in the US and in Europe caused by high concentration of African dust is seen as a major health threat although most of these countries are very distant from the Sahara. Surprisingly, no estimates of PM10 levels near the Saharan dust source are available. Based on horizontal visibility observations which are reduced by the presence of dust in the atmosphere, PM10 levels are estimated at the station of Nouakchott, Mauritania by using relations found in the literature. It appears that excessive concentrations of particles are very important both in magnitude and frequency as the 24-hour PM10 thresholds established by the US EPA National Ambient Air Quality Standards and the EU Limits Values for Air Quality were systematically exceeded. The average yearly concentration is far above air quality standards. These very high particulate levels are likely to represent an important public health threat and should be considered as a major environmental risk. We present here a first comparison between monthly respiratory diseases data and PM10 concentrations due to dust storms. [less ▲]
