The micrometeorological technique of eddy-covariance is used for the estimation of the CO2 exchange between the ecosystems and the atmosphere. Hundreds of instrumented sites, spread all over the world, use it henceforth to study a great variety of ecosystems. This technique is however affected by a systematic error when applied above tall canopies like forests, in stable atmospheric conditions, i.e. primarily during non windy nights without cloud cover. Indeed, during these periods the turbulent transport would be competed with by another transport mechanism which is called advection. In this work, the presence of advection has been tested on the experimental forested site of Vielsalm (Belgium) and its importance has been evaluated. For this purpose, an experimental set-up allowing the measurements of wind velocity, CO2 concentration and temperature of the air inside the forest has been installed. It has allowed the description, for the stable periods, of gravitational flows being carried out close to the ground due to the cooling of surfaces and the presence of a weak slope. These flows were shown to be responsible for advective CO2 transport. An uncertainty analysis has been carried out using dedicated measurement campaigns. It has conclude with the feasibility of measurements of vertical and especially horizontal CO2 gradients on the site but has shown that the greatest factor of uncertainty related to the estimate of the vertical velocity component above and in the forest. In spite of these uncertainties, a fine analysis of the gravitational episodes has made it possible to highlight a coherent mechanism linking the flow field and the CO2 concentration field and making it possible to better understand how CO2 could be transported laterally and vertically by the gravitational flows. Finally, the feasibility of a correction based on the estimate of the advective terms has been evaluated. It has been shown that uncertainties relating to advection were too important to make it possible to appreciably improve the night assessment of CO2 fluxes by means of this method. This one proves however interesting for better understanding the processes of transport at work in a forest cover. [less ▲]

In this work X-ray tomography is used to analyse the influence of liquid viscosity on the local morphology of liquid flow in a column filled with Mellapak Plus 752Y structured packing. Water and glycerine aqueous solutions of various viscosities (1 to 20 cP) are successively used as working liquids. On tomographic images, three different local liquid flow patterns (films, contact-point liquid, flooded regions) may be identified. An image analysis method based on morphological techniques is developed to quantify the fraction of liquid flow within each flow pattern depending on flow rate and liquid viscosity. [less ▲]

Dans cet article, nous proposons une méthode de mesure multidimensionnelle du bien-être des personnes âgées dans l’UE au cours de la dernière décennie. Cette méthode agrège un certain nombre de facettes du bien-être, à savoir les niveaux moyen et relatif de revenus, les taux de pauvreté et d’inégalité, l’espérance de vie et la santé. Cette mesure synthétique permet de comparer les pays européens, d’étudier l’évolution et l’éventuelle convergence du niveau de bien-être des personnes âgées, qui connaissent des moments difficiles avec le vieillissement démographique et la crise financière de nombreux systèmes de retraite.

Pain is a subjective experience. Its assessment is based on the subject's direct verbal report. This method of assessment is, however, impossible in patients who cannot communicate their feelings. In this context, indirect measurements such as behavioral observations or physiological measurements are needed. To facilitate the assessment of pain in non-communicative patients, numerous standardized behavioral scales have been developed. The aim of this review is to discuss the main validated pain scales employed in end-stage dementia, newborn and preverbal children, and severely brain damaged patients with a disorder of consciousness such as coma, the vegetative state or the minimally conscious state.
