Osteoporosis is a medical, social and economical problem for developed countries. Prevention remains the only realistic approach to reduce the burden related to this disorder. Primary prevention of osteoporosis is based on efforts to reach a maximal peak bone mass at the end of the growth period and, subsequently, at the time of menopause. No pharmacological intervention is considered at this stage. Biologically, hormone replacement therapy induces a correction of the biochemical changes observed in markers of bone remodeling at the time of the menopause. A systematic screening of asymptomatic postmenopausal women followed by the induction of hormonal replacement therapy in high risk subjects appears to be an interesting cost/benefit strategy in terms of reasonable attribution of health resources. Nasal administration of calcitonin fully prevents the trabecular bone loss observed during the first years of menopause. Notwithstanding, the exact dose of nasal calcitonin able to prevent bone loss remains to be fully elucidated. Bisphosphonates inhibit bone resorption. Tiludronate prevents trabecular postmenopausal bone loss. The use of selectif estrogen receptor modulators is based on a possible differential action of these molecules, at the level of the estrogenic receptors, depending of the tissue considered. Several direct inhibitors of osteoclastic resorption are also under development. Their main target is either to prevent the linkage of osteoclasts to the bone matrix or to prevent the acidification of bone matrix required to induce the resorption process. [less ▲]

Calcareous grasslands are local biodiversity « hotspots ». Unfortunately, these exceptional ecosystems have undergone a drastic fragmentation since the abandonment of traditional agro pastoral practices. Consequently, many calcareous grassland species are now in danger. In Belgium, since 1990, many hectares of these habitats have been restored to reassemble remaining fragments of calcareous grasslands. The main goal of this work is to participate at the scientific evaluation of calcareous grasslands restoration which took place in the Viroin valley (Namur, Belgium). To reach this goal, information about global and local densities of 2 grasslands species (Helianthemum nummularium and Sanguisorba minor) have been collected on 6 working zones (2 reference grasslands, 2 restored in 1990 and 2 restored in 2006) situated on 2 different sites. Reproductive success traits have been measured on 120 individual samples of each species. Moreover, individuals’ size parameters and some environmental data (soil depth and vegetation structure) have been collected. Results show that global and local densities are lower on recently restored grasslands for both species studied. On the other hand, older restorations and reference grasslands are not significantly different. With regards to the reproductive success of species, individuals on grasslands restored in 2006 have the best results. They produce more flowers, or inflorescences, and more seeds. Differences observed for individuals’ reproductive success have their more probable cause in vegetation structure. The vegetation in the zones that have been restored more recently is more open as the shrubs and trees layer is lower. [less ▲]

Dans un espace clos où se mélangent les nombreuses ondes réfléchies, diffusées et diffractées par les surfaces, la propagation de l’énergie sonore peut être décomposée en deux étapes: tout d’abord, un processus déterministe pour lequel il est possible d’identifier individuellement chaque contribution, suivi d’un processus stochastique pour lequel les contributions doivent être globalisées et vues comme un processus quasi-aléatoire. Le seuil de transition entre les deux comportements est matérialisé dans l’échogramme par le temps de mélange. Dans cette étude, le temps de mélange est analysé en regard de la distribution temporelle du libre parcours. Celle-ci est obtenue numériquement à l’aide du programme de tir de rayons large bande Salrev. Dans un premier temps, le mélange est identifié au travers du caractère asymptotique de cette distribution. Le temps de mélange est alors défini comme la durée (mesurée à partir de l’instant d’émission au départ de la source) nécessaire pour atteindre ce comportement asymptotique. A partir de cette définition du temps de mélange sont étudiées les influences de divers paramètres géométriques et acoustiques. Ensuite, trois applications pour des salles de concert sont réalisées. Cette étude montre que les valeurs obtenues pour le temps de mélange convergent vers celles observées expérimentalement, à condition que les parois de la salle soient suffisamment diffusantes.

In accordance with the Nitrates Directive, the third “Durable Nitrogen Management Plan” (PGDA) will be soon reviewed in Wallonia (Belgium). The second “Nitrate – Water” workshop took place between 28th May and 1st June 2012. The workshop was attended by both Belgian scientists (Université catholique de Louvain - UCL, Walloon Agricultural Research Center CRA-W, Université de Liège - ULg, Gembloux Agro-Bio Tech) and French scientists (National Institute for Agricultural Research - INRA). In the light of the results of experiments presented by scientists at this workshop, modifications to the PGDA are now recommended. These concern organic and mineral nitrogen fertilization for crops and meadows; catch crops; soil nitrate-nitrogen residue limitation in autumn, at the start of the nitrate leaching period; the management of meadow ploughing and a modification of the dairy cow standard for nitrogen production.
