Dans le cadre d’une étude portant sur l’évaluation de la fonction récréative de la forêt wallonne, une enquête a été réalisée entre le 1er mai et le 7 novembre 2005 auprès des utilisateurs de cartes de promenades de 8 organismes touristiques (Florenville, Spa, Saint-Hubert, Nassogne, Assesse, Viroinval, Lobbes et Villersla- Ville). Les personnes acquérant une carte de promenades étaient invitées à répondre à un questionnaire à renvoyer au moyen d’une enveloppe « port payé par le destinataire ». Malgré un faible taux de réponse (196 soit 6,3%), des informations intéressantes ont pu être obtenues sur le profil des promeneurs et sur leurs desiderata. Cet article reprend quelques-uns des principaux résultats obtenus. [less ▲]

We examined immune and inflammatory activation during remission in patients with Crohn's disease who presented with various clinical profiles (prolonged remission vs. relapsing disease). Thirty-six patients with at least 3 years' follow-up starting from a remission period were studied retrospectively. Relapses were defined by a retrospective calculation of the Crohn's disease activity index or by the clinical judgement of the physicians in charge of the patients. Disease course over the study period was assessed by the mean number of annual relapses. Analysis used measurements during remission of the following: erythrocytes sedimentation rate, relative lymphocytosis, acid alpha1-glycoprotein, interleukin-6 (IL-6), and soluble interleukin-2 receptor (sIL-2R) serum levels. During the study period 21 patients experienced at least one relapse and 15 did not. Mean serum levels of sIL-2R and mean relative lymphocytosis in remission significantly discriminated between relapsing and nonrelapsing patients. Only the mean sIL-2R serum level was selected by multivariate analysis, with a cutoff value of 82 pM/1 (sensitivity of 76% and specificity of 80%). The only features correlated with mean number of annual relapses in the relapsing patients were mean serum levels of sIL-2R (r=0.58, P=0.015) and IL-6 in remission (r=0.45, P=0.039). Multivariate analysis demonstrated statistical significance only for the mean serum level of IL-6 (P=0.014). In Crohn's disease the persistent elevation in sIL-2R serum levels during remission corresponds to chronic active disease, while high serum levels of IL-6 in these patients is associated with a high frequency of relapse.

We propose a new family of achromatic phase shifters for infrared nulling interferometry. These key optical components can be seen as optimized Fresnel rhombs, using the total internal reflection phenomenon, modulated or not. The total internal reflection indeed comes with a phase shift between the polarization components of the incident light. We propose a solution to implement this vectorial phase shift between interferometer arms to provide the destructive interference process needed to disentangle highly contrasted objects from one another. We also show that, modulating the index transition at the total internal reflection interface allows compensating for the intrinsic material dispersion in order to make the subsequent phase shift achromatic over especially broad bands. The modulation can be induced by a thin film of a well-chosen material or a subwavelength grating whose structural parameters are thoroughly optimized. We present results from theoretical simulations! together with preliminary fabrication outcomes and measurements for a prototype in Zinc Selenide. [less ▲]

One of the most critical units of nulling interferometers is the Achromatic Phase Shifter. The concept we propose here is based on optimized Fresnel rhombs, using the total internal reflection phenomenon, modulated or not. The total internal reflection induces a phase shift between the polarization components of the incident light. We present the principles, the current status of the prototype manufacturing and testing operations, as well as preliminary experiments on a ZnSe Fresnel rhomb in the visible that have led to a first error source assessment study. Thanks to these first experimental results using a simple polarimeter arrangement, we have identified the bulk scattering as being the main error source. Fortunately, we have experimentally verified that the scattering can be mitigated using spatial filters and does not decrease the phase shifting capabilities of the ZnSe Fresnel rhomb. [less ▲]

Le phénomène des logements vides est en Wallonie un problème urbain de plus en plus sérieux. L’article vise à rendre compte des mécanismes qui concourent à cette multiplication des friches d’habitat. Une première partie est consacrée aux mutations territoriales et immobilières observées en Belgique lors des dernières décennies. En s’appuyant sur l’examen de trois enquêtes, la seconde partie porte ensuite sur les choix d’investissements qui expliquent pourquoi des propriétaires de plus en plus nombreux délaissent leur patrimoine immobilier. La première enquête a été réalisée auprès d’un échantillon représentatif des particuliers actifs sur le marché de la location, la deuxième auprès de propriétaires d’immeubles résidentiels vides et la troisième auprès de propriétaires d’immeubles commerciaux comportant des étages vides.
