The use of data assimilation in coupled hydrodynamic, ecological and bio-geo-chemical models of the ocean The International Liège Colloquium on Ocean Dynamics is organized annually. The topic differs from year to year in an attempt to address, as much as possible, recent problems and incentive new subjects in oceanography. Assembling a group of active and eminent scientists from various countries and often different disciplines, the Colloquia provide a forum for discussion and foster a mutually beneficial exchange of information opening on to a survey of recent discoveries, essential mechanisms, impelling question marks and valuable recommendations for future research. The objective of the 2001 Colloquium was to evaluate the progress of data assimilation methods in marine science and, in particular, in coupled hydrodynamic, ecological and bio-geo-chemical models of the ocean. The past decades have seen important advances in the understanding and modelling of key processes of the ocean circulation and bio-geo-chemical cycles. The increasing capabilities of data and models, and their combination, are allowing the study of multidisciplinary interactions that occur dynamically, in multiple ways, on multiscales and with feedbacks. The capacity of dynamical models to simulate interdisciplinary ocean processes over specific space–time windows and thus forecast their evolution over predictable time scales is also conditioned upon the availability of relevant observations to: initialise and continually update the physical and bio-geo-chemical sectors of the ocean state; provide relevant atmospheric and boundary forcing; calibrate the parameterisations of sub-grid scale processes, growth rates and reaction rates; construct interdisciplinary and multiscale correlation and feature models; identify and estimate the main sources of errors in the models; control or correct for mis-represented or neglected processes.

Tumor necrosis factor-alpha (TNF-alpha) and lymphotoxin-beta receptor (LTbetaR) signaling both play important roles in inflammatory and immune responses through activation of NF-kappaB. Using various deficient mouse embryonic fibroblast cells, we have compared the signaling pathways leading to NF-kappaB induction in response to TNF-alpha and LTbetaR activation. We demonstrate that LTbetaR ligation induces not only RelA/p50 dimers but also RelB/p50 dimers, whereas TNF-alpha induces only RelA/p50 dimers. LTbetaR-induced binding of RelB/p50 requires processing of p100 that is mediated by IKKalpha but is independent of IKKbeta, NEMO/IKKgamma, and RelA. Moreover, we show that RelB, p50, and p100 can associate in the same complex and that TNF-alpha but not LTbeta signaling increases the association of p100 with RelB/p50 dimers in the nucleus, leading to the specific inhibition of RelB DNA binding. These results suggest that the alternative NF-kappaB pathway based on p100 processing may account not only for the activation of RelB/p52 dimers but also for that of RelB/p50 dimers and that p100 regulates the binding activity of RelB/p50 dimers via at least two distinct mechanisms depending on the signaling pathway involved.

The purpose of the presented research project is to investigate how present-day EO-technology can support local and regional decision-making, particularly in Belgium, and to develop prototype versions of value-added products that fulfil some of the actual information needs, as expressed by Belgian authorities at the local and at the regional level. To accomplish this goal the proposal addresses both technical and user-oriented issues, and builds on the experience of five research teams, each with its own background and particular know-how. The most important objectives of the project are: - to define optimal methods for improved spatial information extraction from high- and very-high resolution data, based on innovative processing techniques; - to identify useful EO-applications at the level of local and regional decision making that are made possible by applying the information extraction methods that will be developed; in this case especially 3D information - to define and develop value-added core data products that will support these applications, and that can be consulted with easy-to-use, widely available IT-tools (CD-ROM, Internet, …). One of the technical research modules is focussing on the geometrical aspects of VHR data processing. In terms of spatial resolution, VHR data have the required level of detail to resolve individual objects in the landscape, in a similar way as airborne data. As such, they have the potential of becoming a useful data source for the extraction of detailed, object-related information, and for the production of large-scale cartographic reference data. The geometry of VHR sensor data, however, completely differs from the geometry of aerial photographs (Bethel et al., 2001). Research is going on to evaluate the geometric qualities of present and future VHR standard data products, from the moment they become available, and to examine what level of geometric accuracy is attained with these data, depending on image parameters, processing strategies, and terrain characteristics (Zhou and Li, 2000). The main objectives of the research module on geometric aspects of VHR data processing are: a) to define an optimal procedure for the derivation of envelope DSMs (Digital Surface Models) and ortho-photoplans from VHR data; b) to develop a theoretical model to study the effect of the oblique viewing angle of VHR data on image displacements caused by building height and relief; c) to evaluate the geometric accuracy of satellite-derived envelope DSMs and ortho-corrected image data in comparison with similar products obtained by means of large-scale aerial photography. The module about geometrical aspects is divided into six specific tasks. a) GPS database creation b) Creation of reference envelope DSMs based on aerial photography c) Ortho-rectification of VHR images and aerial photography based on reference DSMs d) Evaluation of the quality of VHR geo-referenced data e) Modelling of displacements caused by terrain morphology and sensor viewing angle f) Development of envelope DEMs from VHR stereoscopic imagery The project is now in the stage where the quality of the georeferenced and orthorectified data is evaluated.

Stroke is the third leading cause of death and the main cause of prolonged disability of adults in industrialised countries. After a first transient ischemic attack or a first minor stroke, the risk of recurrence is 16 folds higher than in control subjects. Therefore each patient suspect of a first ischemic cerebral event should be evaluated for the presence of a specific cause which could be treated. If such a cause is not found, platelet antiaggregant medications should be started. [less ▲]

The hypothesis that prolactin (PRL) functions as an immunomodulator was based on studies showing lymphocyte PRL receptors, and its effects on growth, differentiation, and apoptosis in lymphoid cells. However, studies of PRL (PRL-/-) and PRL receptor knockout mice indicated that PRL was not required for immune system development or function under basal conditions. Because PRL maintains survival in glucocorticoid (GC)-treated Nb2-T lymphocytes in vitro, and PRL and GCs are elevated during stress, we investigated whether PRL protected T cells in vivo from GC-induced apoptosis. Adrenalectomized mice [PRL -/-, undetectable PRL; pituitary grafted PRL-/- (PRL-/-Graft), elevated PRL; and PRL+/-, normal PRL] were treated with dexamethasone (DEX) or PBS. Thymocytes and splenocytes were isolated and annexin V labeling of phosphatidylserine, DNA fragmentation, and caspase-3 activation were assessed as indices of apoptosis. Total thymocytes and CD4+ and CD8+ T cells obtained from DEX-treated PRL-/- mice exhibited significantly increased annexin V binding. In contrast, binding was not altered by DEX in PRL-/-Graft thymocytes. In addition, DEX induced classic DNA fragmentation in PRL-/- thymocytes. Elevated serum PRL reduced this effect. Thymocytes from DEX-treated PRL-/- mice exhibited increased caspase-3 activation, which was inhibited in cells from PRL-/-Graft mice. Finally, elevated expression of X-linked inhibitor of apoptosis, XIAP, was observed in thymi from DEX-treated PRL -/-Graft mice. This is the first demonstration that elevated PRL antagonizes apoptosis in thymocytes exposed to GCs in vivo. These observations suggest that, under conditions of increased GCs, such as during stress, elevated PRL functions physiologically to maintain survival and function of T-lymphocytes. [less ▲]

Hamlet est une pièce qui s’adresse à tous les publics ou, à tout le moins, aux publics disposés à se poser, avec Hamlet, d’innombrables questions sur des sujets tels que la vie et la mort, l’action et l’inaction, l’amour ou encore la vengeance. Laurence Olivier a dit qu’il pourrait jouer Hamlet pendant cent ans et lui trouver un nouveau sens à chaque représentation. Le personnage est ambigu, presque insaisissable, en effet, comme l’est la langue de la pièce. Mais cette ambiguïté renforce la richesse de Hamlet plutôt qu’elle ne l’appauvrit ; et c’est précisément ce mystère qui permet à chaque lecteur et à chaque acteur de se livrer à une lecture personnelle et intime du personnage, de faire sienne sa complexité. Hamlet, c’est lui, toi, moi, c’est nous tous ; étant nous tous, il est universel, le mythe que chacun d’entre nous essaie, dans son individualité, de comprendre et ne peut s’empêcher de reconnaître dans sa propre nature. Les lectures de Hamlet sont innombrables et sont fonction de la personnalité du lecteur de la pièce, du metteur en scène et de l’acteur. Hamlet est un des rares personnages du théâtre, peut-être le seul, qui permette un échange constant. Chacun de nous, quel que soit son âge, peut se reconnaître en lui et peut façonner le mythe de Hamlet à son image. * Ne présupposant aucun savoir particulier, cet ouvrage introductif — destiné à la fois au grand public et aux étudiants de l'enseignement secondaire et du premier cycle universitaire — offre un aperçu critique des principaux thèmes de Hamlet tout en permettant au lecteur de se familiariser avec les interprétations et les prolongements littéraires et cinématographiques de la pièce.

Le principal objectif visé par le présent travail est de mettre au point des catayseurs efficaces, capables de polymériser par voir radicalaire contrôlée des oléfines internes (peu réactionnelles) et, plus particulièrement, l'huile de lin.Nous tenterons aussi d'aborder la copolymérisation de l'huile de lin avec des monomères de grande consommation (styrène et (méth)acrylates) afin de mettre au point, au départ d'un produit naturel et renouvelable, des matériaux nouveaux. L'huile de lin est constituée d'un mélange complexe de triglycérides dont les chaînes pendantes sont porteuses de 2 ou 3 liaisons C=C doubles. Face à la diversité et à la complexité structurale de ces molécules, il nous parait évident d'aborder le problème de manière plus systématique en nous basant sur l'étude de la polymérisation d'oléfines internes et/ou fonctionnalisées qui serviront de "modèles" pour celles rencontrées dans l'huile de lin. Nous sommes en effet convaincus que la réussite de ce projet passe avant tout par une bonne compréhension des facteurs qui gouvernent la réactivité des oléfines internes et fonctionnalisées. Ce projet est réalisé dans le Laboratoire de Chimie Macromoléculaire et de Catalyse Organique (CERM) de l'Université de Liège en partenariat avec l'Institut des Sciences de Matériaux (ICMAB, Barcelone) et la Société Vandeputte (Belgique [less ▲]
