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 ▲]

The aim of this laboratory experiment was to examine courtship behavior and reproductive success under two different perceived male densities ill the Alpine newt (Triturus alpestris). Male behavioral patterns were similar at unbiased and male-biased operational sex ratios (OSR). Although the exhibition of hiring behaviors is risky in the presence of other males, no difference in the frequencies of displays was found at the two male, densities. Similarly, the responsiveness of females towards males and the Success rate of the encounters (i.e. spermatophore transfer) were not explained by file OSR. Our results show that courting Alphine newts do not change their courtship patterns when other males are present and do not interact directly. However they are not necessarily opposed to those of previous experiments showing sexual interference awl ,female aversion in male-biased OSR with possibility of interactions. These observations suggest that the evolution of courtship behavior may not be driven by the risk of sexual interference with other males prior to potential physical contact and that the benefits of breeding regardless of OSR can overcome the risk of Competition at male-biased OSR.

La Stratégie européenne de sécurité adoptée en décembre 2003 par l'Union européenne définit un cadre normatif et des principes directeurs. En cela, elle n'est pas un véritable concept stratégique et encore moins une doctrine. Sorte de philosophie générale de l'action dans le monde, le "document de Solana" renvoie à des lectures et à des interprétations idéologiques de la sécurité fortement divergentes, faisant ainsi montre d'ambiguïtés et d'imprécisions volontaires.

Cet article livre une analyse approfondie d’un tableau désormais conservé au musée Grand Curtius à Liège. Jadis attribuée à Albert Bouts, cette œuvre doit aujourd’hui être attribuée à un anonyme flamand actif vers 1530. En outre, les analyses de laboratoire que j’ai effectuées sur le tableau ont montré qu’il a subi une importante campagne de falsification dans le courant du XIXe ou du XXe siècle. [less ▲]
