The Sahara and its margins largely contribute to the global injection of mineral dust into the northern hemisphere, about half of the yearly global mineral dust production. In this study, we have placed a pyramidal receptacle in Mâle (southern Mauritania) during the rainy season 2005 in order to measure daily Saharan dust deposition. The dust quantity collected totals 78.38 g/m2 during the 3 months experimented. Comparing our results to previous works achieved in the southern border of the Sahara shows that the levels of deposition in Mâle are extremely high. This could suggest a continuous environmental degradation resulting from always increasing human pressure. [less ▲]

On the basis of an exhaustive consultation of the literature describing the temporal evolution of land cover in arid, semiarid and dry subhumid regions of West Africa, this study shows that the deforestation trend has been very important during the second half of the 20th century. This trend to deforestation is globally large (2% per year) and is clearly alarming. Although our results differ from FAO's official data, it is demonstrated that those are questionable. In addition, if dense woody formations have been strongly reduced in the study area, our study indicates that degraded woody formations are currently declining. Our results clearly go against the recent conclusions of some authors preaching the idea of a 'greening Sahel'. [less ▲]

The analysis of risk of flood downstream from the hydroelectric dam of Nangbeto in the Mono River was about the survey of interannual variability of rainfall and rivers flows from 1955 to 1999, the population vulnerability, the hydrological modification and the impacts downstream in Togo and Benin from the dam constructed in 1987. The analysis of the mean annuel discharge has revealed no tendency, showing thus that the change of land use, the increase of waterproof areas and even the functioning of the hydroelectric dam have not modified in a significant manner the river's rate of flow. Apart from the return to the improvement in rainfull as far back as the end of years 80, the anthropic pressure and the demographic explosion have best explained the magnitude and frequency of flooding downstream from the hydroelectric dam of Nangbeto. The soil degradation, the deforestation of the floodplain, the increase in the number of human settlements in the river boundary increases the vulnerability of population faced with flooding.

Vasculitic neuropathies require early diagnosis and therapy since their prognosis is potentially severe. The following features are usually suggestive of a vasculitic neuropathy: painful multiple mononeuropathy with an acute/subacute course, signs and symptoms of multisystem involvement (arthritis, asthma, renal and skin involvement), biological evidence of an inflammatory syndrome. In one third of patients however, vasculitic neuropathies present as a polyneuropathy. For other patients, peripheral neuropathy is the presentation mode of a necrotizing vasculitis, in the absence of biological inflammatory syndrome. A combined muscle and nerve biopsy, will usually demonstrate the vasculitic process. Vasculitic neuropathies often have a favourable prognosis when immunosuppressive therapy (corticosteroids and/or cyclophosphamide) is initiated at an early stage. [less ▲]

De nombreux travaux montrent que les évolutions urbaines contemporaines s’inscrivent dans un processus de recomposition des villes induit par la mobilité facilitée et par la banalisation de la conduite automobile. Dans le cadre de cet article, nous traitons cette thématique en étudiant, pour le contexte belge, comment le relâchement des freins à la mobilité interfère avec les logiques résidentielles des familles en formation. Un bilan sur la situation contemporaine est d’abord dressé. Nous y présentons les principaux liens entre choix résidentiels, classes d’âges et parcours de vie. Nous y analysons aussi les relations entre, d’une part, le constat de l’étalement périurbain et, d’autre part, la pression foncière à laquelle les ménages en formation ont à faire face. En seconde partie, la situation contemporaine est confrontée aux évolutions des cinq dernières décennies. Ces analyses réalisées pour la région urbaine de Liège permettent de combiner les trois grilles explicatives du moment du cycle de vie, de l’effet du renouvellement des générations et de l’impact du contexte socio-économique. De ce travail, nous relevons que la mobilité facilitée conduit à dilater les inscriptions démographiques. Comme les groupes sociaux, les groupes démographiques sont, en effet, de plus en plus spatialement ségrégés dans une région urbaine très largement recomposée par la mobilité automobile. [less ▲]

The aim of this study is to give some guidelines for a phenomenological metaphysics. The author first questions the possibility and relevance of applying the phenomenological method in metaphysics, in order to outline a metaphysics that would be not only a "metaphysical systematics" (in Peter Simons's sense), but also a phenomenological and "constitutive" metaphysics. Then he succinctly explores some basic questions of contemporary metaphysics, in a dialogue with the recent developments of "analytical" metaphysics: Armstrong's factualism, the relationship between logic and ontology, the ontological status of universals, maximalism and negative states of affairs, ontological dependence, Moore's paradox, etc. [less ▲]

A method to sort 'Jonagold' apples based on the presence of defects was proposed. A multi-spectral vision system including four wavelength bands in the visible/NIR range was developed. Multi-spectral images of sound and defective fruits were acquired tending to cover the whole colour variability of this bicolour apple variety. Defects were grouped into four categories: slight defects, more serious defects, defects leading to the rejection of the fruit and recent bruises. Stem-ends/calyxes were detected using a correlation pattern matching algorithm. The efficiency of this method depended on the orientation of the stem-end/calyx according to the optical axis of the camera. Defect segmentation consisted in a pixel classification procedure based on the Bayes' theorem and non-parametric models of the sound and defective tissue. Fruit classification tests were performed in order to evaluate the efficiency of the proposed method. No error was made on rejected fruits and high classification rates were reached for apples presenting serious defects and recent bruises. Fruits with slight defects presented a more important misclassification rate but those errors fitted however the quality tolerances of the European standard. Considering an actual ratio of sound fruits of 90%, less than 2% of defective fruits were classified into the sound ones. (c) 2004 Elsevier Ltd. All rights reserved. [less ▲]

Contexte: La formation des futurs médecins doit prendre en compte la portée éthique, socio-environnementale, économique, juridique et psychologique de l’action médicale ainsi que ses aspects pluridisciplinaires. Dans le cadre d’un renouveau pédagogique décidé en Faculté de Médecine de l’Université de Liège, une modalité particulière de l’apprentissage par problèmes, les séances d’Apprentissage à la Résolution de Problèmes complexes (ARPc), a été instaurée. Buts : Les auteurs rapportent la méthodologie spécifique, étayée par des exemples concrets, développée lors de l’instauration des séances d’ARPc ainsi que les premières analyses d’une procédure d’évaluation qualitative. Sujet : Le dispositif s’adresse aux étudiants des deux dernières années du 2e cycle de formation médicale. Les objectifs pédagogiques spécifiques des ARPc sont l’approche de la complexité contextuelle de toute pratique médicale et l’initiation au travail pluridisciplinaire. Résultats : Les premières procédures d’évaluation qualitatives ciblant étudiants et enseignants donnent des résultats assez favorables. Conclusion : L’expérience est poursuivie moyennant quelques aménagements organisationnels mineurs. Elle s’ouvre à d’autres disciplines médicales et fait l’objet d’une évaluation quantitative à publier ultérieurement. [less ▲]

Histone deacetylase (HDAC) inhibitors are a novel class of promising anti-cancer agents. Little information is available on the capacity of structurally different HDAC inhibitors to induce terminal cell differentiation in different cell types in relation to enzyme inhibition and subtype selectivity. Consequently, the aim of this study was to provide a comprehensive comparison of these effects. New biarylalanine inhibitors of HDAC were synthesized and compared to a series of standard inhibitors from different laboratories. Chromatographically purified rat liver and immunoprecipitated FLAG-tagged recombinant human HDACs were used as sources of HDAC activity. Enzyme inhibition was studied using a fluorescent substrate and its conversion was monitored by high-performance liquid chromatography. The ability to induce cell differentiation was compared in murine (Friend DS-19) and human (K562) erythroleukemic cell lines, and was quantified by benzidine staining. Inhibition of cell proliferation was evaluated by cell counting. All HDAC inhibitors were identified as potent inhibitors of erythroleukemic cell proliferation. However, we observed a complex pattern of differentiation induction: structurally similar inhibitors resulted in disparate activity profiles, whereas similar profiles were detected within distinct structural classes. Among the newly synthesized biarylalanine compounds, a 3'-methoxy derivative was identified as a very effective inducer of terminal cell differentiation. We conclude that investigation of subtype selectivity of selected HDAC inhibitors does not provide a clear link between selectivity and the observed cellular activity profile. The predictive value of in vitro HDAC inhibition assays for identifying anti-proliferative compounds has been emphasized. [less ▲]
