[more ▼] The main objective of the present study is to introduce a rational method of aiding to design the envelope of a building, during the sketch design. The design method has for both objectives the respect of building costs (for the construction itself and in use), and the improvement of the energy performance. In the multicriteria and multiactors context, this interactive tool is using decision-making aids, in order to improve the architectural response to the client’s and regulations requirements, while aiding: - the project authors in their conception tasks, by making up the project architectural forces, in accordance with the actors’ objectives; - and the client in his participation in the multiple partners negotiation.

The existing methods were unsatisfactory for diverse reasons as limited measurement length or insufficient accuracy. Two different sensor data fusion methods were evaluated as input for a model aimed at predicting longitudinal spray deposit. A combination of radar and two accelerometers measurements was found more suited than laser and radar measurements combined in predicting spray repartition.

[more ▼] In order to investigate the effect of CO2 addition in the combustion air of a yellow flame burner, tests have been performed during which different volume flow rates of CO2 have been injected. For all the tests performed, the burner consumption and the oxygen mole fraction in the flue gas have been kept quite constant, say at about 240 kW and 1.8 % (on dry basis) respectively. For the interpretation of the flame radiation results, tests have also been performed with N2 injection. The results gathered (for CO2 and N2 addition up to 4.8 % and 7.4 % in volume respectively) show that the thermal efficiency and the CO emission of the boiler are not affected. For small amounts of CO2 or N2 volume flow rates, there is a slight decrease of the NOx emission and the flame radiation. If the quantity of the additive is increased above a critical value, the flame becomes unstable and one observes first a sudden increase of the NOx emission and the flame radiation and then a decrease. That sudden increase is explained by the change of the flame shape and geometry.

[more ▼] Recent developments in theory insist on the existence of a plurality of individual realities within the same social group. However, the logic of understanding used to analyse these realities in the empirical research still relies too much on a univocal perspective in which the concepts are perceived to be homogeneous. This manner of approaching reality legitimates the linear explanations of attitudes and individual behaviours. But a reflection on the effective processes of constructing the individual worlds of reference based on a psychological perspective strongly challenges this logic. Thus, the works of Jean Piaget clearly show that the individual is not a passive being in the dynamics of appropriating the world, but that he or she assimilates the social context, accommodates it to what he or she already understands and thereby transforms it. This theoretical framework opens the path to an interesting form of conceptual relativism where every concept has to be replaced into the context as it is structured by the individuals’ worlds of reference. This relativity presents a challenge to empirical research: Which principle of synthesis would allow us to respect the theoretical plurality proposed by the piagetian interpretation? So far, we have mostly used a methodology based on the classificatory approach in our research, but we are by now more aware of its limitations as well.

[more ▼] Trois types de producteur primaire prolifèrent dans la zone photique côtière méditerranéenne. En dehors des zones d’upwelling et des apports côtiers naturels ou d’origine anthropique, le bloom phytoplantonique est de courte durée et les eaux méditerranéennes sont très claires. Les algues benthiques ont une biomasse relativement faible et le principal producteur primaire est l’herbier à Posidonia oceanica (L.) Delile. Cet herbier constitue un écosystème complexe, d’une importance cruciale pour l’équilibre côtier (maintien des côtes, production d’oxygène, plusieurs milliers d’espèces y sont inféodées…). Son influence se fait également ressentir bien au-delà de sa limite de distribution (exportation vers les zones profondes). Les feuilles et les épiphytes de l’herbier sont à la base de nombreuses chaînes trophiques. Les rapports isotopiques (13C/12C et 15N/14N) mesurés dans les tissus d’un animal reflètent ceux de son alimentation avec un léger enrichissement d’un niveau trophique à un autre. Cet discrimination en faveur des isotopes lourds est de l’ordre 30/00 pour le 15N et de 10/00 pour le 13C. Les rapports 15N/14N permettent donc la détermination de la position trophique d’un organisme. Les rapports 13C/12C sont plutôt de bons indicateurs des sources de production primaire. L’application de cette technique au cas d’un herbier à P. oceanica, a permis sur base des rapports 13C/12C de distinguer trois sources primaires de nourriture: la matière particulaire en suspension, les algues (épiflore de P. oceanica et macroalgues) et P. oceanica. Les rapports isotopiques 13C/12C et 15N/14N de différentes catégories trophiques d’organismes capturés dans l’herbier et dans une communauté épilithe adjacente suggèrent que les sources de nourriture sont semblables dans les deux communautés: la matière particulaire en suspension et les algues. La communauté épiphyte des feuilles de posidonie est une source de nourriture très importante pour les organismes de la canopée de l’herbier. Les posidonies ne représentent qu’une partie mineure du régime alimentaire des organismes étudiés à l’exception des holothuries et du téléostéen herbivore Sarpa salpa. Ce poisson est l’un des consommateurs principaux de posidonie vivantes mais la majorité de sa nourriture provient de matériel algal. Les holothuries psamivores assimilent massivement des détritus issus de P. oceanica et jouent ainsi un rôle clé dans le recyclage in situ de ce matériel. La disponibilité en nutriments, en particulier de l'azote inorganique, est un des facteurs majeurs déterminant la dynamique des écosystèmes à phanérogames marines. Le budget en azote de ces plantes est très complexe car elles ont la capacité d'incorporer les nutriments dissous dans la colonne d'eau et dans l'eau interstitielle du sédiment. De plus, le recyclage interne de l'azote est souvent considéré comme un processus clé pour assurer les besoins de la plante. Des expériences utilisant l'isotope 15 de l'azote comme traceur nous ont permis de mesurer in situ l'incorporation de nitrate et d'ammonium ainsi que le recyclage interne de l'azote par P. oceanica. L'incorporation d'azote exogène par les feuilles ne représenterait que 25% des besoins annuels en azote de la plante et le recyclage 40%. Par différence, nous pouvons estimer que l'incorporation d'azote par les racines représenterait environ 35% des besoins annuels en azote de la plante. Nos études isotopiques se sont également avérées particulièrement intéressantes dans la compréhension des processus de transfert de matières organiques ou de polluants au niveau des échelons trophiques supérieurs (thons et dauphins de l’Atlantique nord et mammifères marins de la Mer du Nord). En effet, au sein d’un même écosystème peuvent coexister différentes espèces de prédateurs nécessitant des ressources similaires. L’analyse simultanée des isotopes stables du carbone et de l’azote a permis une définition plus fine de l’écologie alimentaire de ces espèces.

[more ▼] Cet article traite de la mise en œuvre de diverses pratiques pédagogiques visant à développer des compétences utiles à l'autoformation chez des étudiants universitaires. L'enjeu est d'amener ces derniers à prendre en charge une ou plusieurs phases du processus d'autoformation (Leclercq et Denis, 1995). Différents contextes sont pris en compte : cours dans de grands auditoires (200 à 500 étudiants), en petits groupes (10 à 15) ou en groupes de taille moyenne (30 à 40). Différents scénarios pédagogiques qui tous favorisent un apprentissage actif et le développement de compétences utiles pour devenir un bon auto-apprenant combinent certains des six paradigmes d'apprentissage/enseignement définis par Leclercq et Denis (1998). Ces scénarios sont la méthode des exposés structurés, l'amphithéâtre électronique, l'apprentissage collaboratif basé sur des problèmes et les PARM (Projets d'Animation Réciproques Multimédias). Les auteurs indiquent dans quelle mesure ces stratégies pédagogiques contribuent à faire atteindre des objectifs répondant aux diverses phases du processus d'auto-formation : définition des besoins d'apprentissage, définition d'un projet personnel de formation, fixation d'un plan d'action, action de formation, auto-évaluation et décisions éventuelles d'auto-régulation du processus. Un modèle d'architecture des compétences à faire acquérir par les apprenants (Leclercq, 1987) est proposé et mis en relation avec les scénarios pédagogiques expérimentés. Il traite à la fois de compétences transversales et spécifiques. Quatre niveaux sont distingués : les compétences dynamiques se rapportent à la motivation des apprenants, à leur représentation d'eux-mêmes en tant qu'individus capables d'apprendre ; les compétences stratégiques relèvent entre autres de conduites de résolution de problèmes, de la planification des tâches, des interactions sociales et de la métacognition ; les compétences démultiplicatrices sont celles qui permettent d'accéder à de nouveaux savoirs ; les compétences spécifiques sont liées à des contenus, des procédures, généralement non transférables. Une liste de compétences techniques permettant aux apprenants de situer leurs apprentissages et d'auto-évaluer leur maîtrise de divers outils technologiques - utiles notamment dans la mise en œuvre de formations à distance - est également décrite ainsi que son utilisation pratique (Denis, 2000).

[more ▼] The importance of trophic relationships between rotifers and protozoans in rivers are not yet well known, but as some authors have shown during the last decade, the predation exerted by rotifers on these organisms might be of importance in the transfer of energy from the pico- and nanoplankton to the metazooplankton. Fluorescent polycarbonate beads of 0.45 µm in diameter were used to label the ciliate Tetrahymena pyriformis. Different combinations of labelling times and concentrations of microspheres were tested to achieve an optimal labelling of the ciliates (i.e. a maximal proportion of individuals having ingested the same number of microspheres). Live labelled Tetrahymena pyriformis were used to determine both the gut passage time and the ingestion rate of the rotifer Brachionus calyciflorus. The ingestion rates measured with relatively high densities of ciliates (from 30 to 500 cells.ml-1) were on average of 30 cells.ind-1.day-1. The ingestion rates yielded by this method were compared with ingestion rates measured by assessing the disappearance of the ciliates in experimental media during 5-6 hour incubations. Results from both methods were comparable but the use of fluorescently labelled prey items produced less variable results.

[more ▼] GeoArabia Special Publication 1 <br /> <br />Knowledge of the Palaeozoic biostratigraphy of the Arabian Peninsula, situated close to the northern margin of Gondwana, was poorly known until a joint special project was held by the Saudi Arabian Oil Company (Saudi Aramco) and the Commission Internationale de Microflore du Paléozoïque (CIMP) in 1990. Prior to that only a small number of investigations had been published. Few efforts had been made to exploit the strati-graphic potentials of the many undescribed indigenous microfossils. The joint Saudi Aramco-CIMP project was designed to reverse that situation. Comprehensive studies were carried out on a range of microfossil groups throughout the Palaeozoic and results were published in 1995. <br /> <br />The 13 papers presented in this GeoArabia Special Publication update those initial findings. They clearly indicate the potential for these palynomorph assemblages to not only to provide a method for well-to-well correlations within Saudi Arabia, but also for establishing the palaeo-biogeographical relationships of the Arabian Plate relative to adjacent landmasses. The conclusions that are proposed here can now be compared with datasets throughout North Africa and with the central and southern parts of South America. <br /> <br />Editors: Sa’id Al-Hajri and Bernard Owens <br />231 pages <br />40 plates/62 illustrations [less ▲] Detailed reference viewed: 21 (6 ULg) Groundwater pollution in an agricultural catchment on sandstone : evaluation of water and nitrogen losses from soils.; ; et al Conference (2000) Detailed reference viewed: 3 (1 ULg) Local buckling of structures in case of fireFranssen, Jean-Marc ; Conference (2000) Detailed reference viewed: 7 (1 ULg) Palynological characterization and dating of the Tiangua Formation, Serra Grande Group, Paranaiba Basin, northern Brazil; ; et al Conference (2000) Detailed reference viewed: 6 (2 ULg) Detection of the 67-kD laminin receptor in prostate cancer biopsies as a predictor of recurrence after radical prostatectomyWaltregny, David ; de Leval, Laurence ; Coppens, Luc et alConference (2000) INTRODUCTION & OBJECTIVES: The identification of reliable prognostic indicators for prostate cancer (PC) is a major challenge of today cancer research.

[more ▼] INTRODUCTION & OBJECTIVES: The identification of reliable prognostic indicators for prostate cancer (PC) is a major challenge of today cancer research. The 67-KD laminin receptor (67LR) is a cell surface associated molecule whose increased expression is associated with the aggressiveness of a variety of human cancers. We recently showed that 67LR detection in PC tissues from radical prostatectomy (RP) specimens was an independent predictor of biochemical relapse in patients with clinically localized PC (JNCI, 89:1224-1227, 1997). In this study, we assessed 67LR detection in diagnostic biopsies as a predictor of biochemical relapse after RP. MATERIAL & METHODS: A total of 151 patients with clinically confined PC underwent RP. PC tissue sections from both biopsy and RP specimens were immunohistochemically analyzed for 67LR expression. The importance of 67LR expression was evaluated according to the intensity and extent of the staining. Preoperative and postoperative clinicopathological parameters, including 67LR expression, were correlated with each other and tested as predictors of biochemical relapse. RESULTS: 67LR was detected in 67.5% and 68.2% of biopsies and RPs, respectively. 67LR detection in RP specimens was an independent predictor of relapse. The level of 67LR expression in the biopsy was significantly associated with the biopsy Gleason score (p<0.05) but failed to predict the pathological stage (p>0.1). Biochemical progression-free estimates for patients whose biopsy did or did not express the protein differed with only borderline statistical significance (p=0.05). Multivariate analysis identified biopsy Gleason score as the only independent preoperative predictor of recurrence. Significant discrepancies in levels of 67LR expression were found between matched biopsy and RP specimens, with exact agreement rates <40% (p<0.05). CONCLUSIONS: 67LR detection in PC biopsies was not a significant preoperative predictor of outcome after RP. Heterogeneity of 67LR expression and biopsy sampling errors most likely represented the main raisons for discordant prognostic results depending on whether 67LR expression was evaluated either in biopsies or in RPs.
