L’oxydase alternative (AOX) est une ubiquinol-oxygène oxido-réductase qui au niveau mitochondrial, catalyse l’oxydation de l’ubiquinol en transférant directement ses électrons à l’oxygène. De part son activité catalytique, cette protéine entre en compétition avec le complexe III et est donc un système dissipateur d’énergie puisque les électrons transférés par AOX à l’oxygène ne contribueront pas à l’établissement du gradient électrochimique de protons par la voie des cytochromes. Dans cette étude, nous avons voulu déterminer l’impact de l’expression hétérologue d’AOX chez un organisme qui en est naturellement dépourvu : Saccharomyces cerevisiae. L’expression d’AOX chez S. cerevisiae est fonctionnelle et conduit à une augmentation du temps de génération de 30% par rapport à la souche contrôle. De manière à identifier les voies métaboliques affectées par l’expression d’AOX chez la levure, nous avons réalisés une étude protéomique sur le protéome mitochondrial et cellulaire par l’approche SILAC. Le SILAC (stable isotopic labelling by amino-acid in cell culture) est une technique de protéomique comparative qui permet de calculer directement les changements de niveau d’expression des protéines par spectrométrie de masse, contrairement aux gels 2D, ou les changements sont estimés par densitométrie. Cette technique se base sur l’incorporation d’un acide aminé « lourd » ou « léger » lors de la traduction des protéines lors des cultures cellulaire. L’incorporation de ces acides aminé va induire en spectrométrie de masse, un décalage de masse entre deux peptides de même séquence et rendre possible directement la comparaison des niveau d’expression a calculant le rapport d’intensité des deux pics. En comparant le protéomes mitochondrial, nous avons remarqué une augmentation générale du niveau d’expression de tous les enzymes du cycle de Krebs. Cette augmentation est accompagnée par une augmentation du niveau d’expression des NADH déshydrogénases interne et une diminution de la NADH déshydrogénase externe suggérant une augmentation de l’entrée des électrons dans la chaîne respiratoire via la production d’équivalents réducteurs par le cycle de Krebs plutôt que par les équivalent réducteurs issus du cytoplasme. En comparant les protéomes cellulaires, nous avons observés une diminution globale de toutes les protéines mitochondriales suggérant une diminution de la masse mitochondriales par cellules. Cette diminution est accompagnée par une augmentation générale de la glycolyse d’un facteur 2,5. [less ▲]

Hybrid Hydraulic Vehicle (HHV) technology is an alternative to HEV. This technology deserves new attention because of recent development in reversible hydraulic motor pumps with high efficiency. The HHV technology is based on parallel architecture of motor assist systems. A first preliminary study investigated the fuel consumption of a passenger car, a SUV and an urban bus. It clearly demonstrated that the fuel efficiency benefits are the better for heavy vehicles with frequent stops and starts. The second part of the work then compared both HEV and HHV buses. The fuel consumption is simulated using ADVISOR on the basis of 3 SORT driving cycles. The results showed that the HHV are penalized by his weight but they can be economically interesting because of the lower cost and longer life time of the hydraulic system. [less ▲]

New technology in surgery is more and more present and allows to study cognitive processes in complex and natural environment. Comparing to classical minimal access surgery, a new robotic system allows to recover a 3D view and all degrees of freedom for instruments movement. The purpose of this study was to evaluate the perceptual (2D vs 3D view) and instrumental (classical versus robotic) impacts of this new robotic system on learning curves. 40 medical students without any surgical experience were randomized into 4 groups (classical laparoscopy with 3D-direct view or with 2D-indirect view, robotic system in 3D or in 2D) and repeated a surgical task 6 times. After these 6 repetitions, they performed 2 trials with the same technique but in the other viewing condition (perceptive switch). Finally, subjects performed last three trials with the technique they never used (technical switch). We measured the speed, the accuracy and their subjective impressions about their performance (satisfaction, self-confidence and difficulty). Our results showed better performance and improvement in 3D view than in 2D view, whatever the instrumental aspect. Participants reported less mastery, familiarity, self-confidence and more difficulty in classical laparoscopy with 2D view than in the other conditions. In conclusion, robotic surgery improves surgical performance and learning, particularly by 3D view advantage. However, the bad performances after the perceptive and technical switches emphasize the need to adapt and pursue training also with traditional technology in order to prevent risks when a robotic procedure has to be converted in a classical laparoscopic procedure.

Very few main-sequence stars exhibit warm dust in their 5-10AU close environment, where terrestrial planets are expected to have formed. Near-infrared interferometry is a powerful means, combining high dynamic range and high spatial resolution, to directly detect faint emission from hot grains in exozodiacal clouds. We will review the results of our search for 2 micron excesses around Vega-like stars, including the nearby Sun-like stars Tau Ceti and Epsilon Eridani, with the FLUOR interferometric instrument and the CHARA Array of telescopes. Our recent detections, combined with Spitzer observations around 10 micron, put strong constrains on the properties and distribution of hot grains in these inner planetary systems. We will present the conclusions of our preliminary modeling for the detected hot grains as well as their implication for the selection of targets for future planet finding missions like DARWIN or TPF.

Until now, the choice of a heating system is, in most cases, rather intuitive, but not based on significant comparisons among the many options available on the market. Friendly calculation tools are badly needed. A prototype of simulation model is shortly presented in this paper. It is designed as a preliminary design tool, allowing the different partners of a project to evaluate the energy impact of the very first design options: building envelope heat transfer coefficients, glazing areas, orientations, solar factors, ventilation mode, heat emission, distribution, generation and control strategy. The heating demand is calculated hour by hour with consideration to the time variations of inside and outside temperatures and free gains, to the control law and to the heating power actually available. The emitter is a water-ambient heat exchanger. It may have some thermal mass. Two emitters are here proposed: the radiator and the flow heating system. A steady state water distribution model is included in this simulation; it takes heat losses in unheated spaces into account: Three typical heating sources are proposed: classical boiler, condensing boiler and heat pump. All heat generators are here simulated with the help of very simple polynomial (“daughter”) models. The polynomial expressions are fitted on the simulation results obtained with reference (“mother”) models, themselves fitted on experimental data available. Examples of simulation results are presented in the paper. [less ▲]

Malgré la hausse sensible que connaît l’e-commerce, la problématique de la confiance afférente aux transactions électroniques reste d’actualité. Axée sur les choix des entreprises en matière d’e-business/e-commerce, notre contribution propose d’analyser l’influence qu’est susceptible de revêtir à cet égard la nature des transactions, vue sous les caractéristiques de spécificité des actifs et de récurrence de la relation (Williamson, 1975, 1985). Il en résulte quatre comportements distincts de la part des entreprises, en lien avec leur perception des enjeux liés à la confiance et au risque entourant les transactions électroniques. Basé sur l’analyse transversale d’une vingtaine d’études de cas, notre propos met ainsi en évidence des positionnements stratégiques contrastés et un recours à des mécanismes de protection différents suivant la spécificité des actifs échangés et la récurrence de la relation entretenue avec les cocontractants.

The work presented here consists in developing an audit methodology, with appropriate simulation tools and benchmarks. Several case studies are used to support, to test and to illustrate these developments. Each case study is described according to a standard format, in order to make the data easy to re-use in the future. The audit of the HVAC system consists in analyzing the information available about actual energy performances and in identifying the most attractive retrofit opportunities. Focus is given here to cooling energy consumption, but it could never be completely dissociated from heating requirements. An example of case study is presented in the paper to give a first idea of what could be the (difficult) task of the energy auditor. One of the main difficulties comes from the too many information lacks. Filling these lacks would require, in most case, more detailed energy records on site. Simulation models may help a lot, for a better interpretation of on site records and also for a safe identification of the most promising retrofit opportunities. Such models and examples of simulations are presented in the paper. [less ▲]

Using water resources for hydro-electricity production influences and limits the quality and quantity of habitat available for use by resident fishes. Changes in the fish community structure after setting minimum flow conditions have been more frequently studied than the behavioural adaptations of fish living in the vicinity of the disturbed river section. In the River Amblève (River Meuse basin, Belgium), a hydraulic power plant bypasses the river over a length of 10 km. Adult nase Chondrostoma nasus (n=10) and barbel Barbus barbus (n=8) were captured in the restitution zone of the turbinated flow several weeks before their reproduction periods. They were equipped with implant radio transmitters and manually and intensively tracked over several months to more than 1 year. The environmental conditions (water temperature and flow) as well as the geomorphology of the river were compared in both natural and flow-regulated sections. Nase and barbel demonstrated the capacity to map their contrasted environment and adapted their space and habitat utilisation as well as the choice of their spawning sites in relation with their specific biological characteristics and the environmental variations. The results are discussed in the context of the management of fish movements in flow-regulated rivers. [less ▲]

Habitat preferences of Atlantic salmon parr are commonly described using mean flow velocity, water depth, and substrate as habitat variables, and a variety of habitat models have been developed using these variables to predict habitat quality. However, Atlantic salmon parr live in highly turbulent streams and rivers, in which intense fluctuations of flow velocity occur. Habitat preferences that consider the high variability of flow velocity have not been studied, and this although it has been shown in laboratory experiments that turbulence may affect the behavior and energetics of fish. Consequently, we studied the use of turbulent flow by Atlantic salmon parr in Patapédia River, Québec, Canada using radio-telemetry. We analyzed summer habitat preferences of individual parr in relation to several dynamic hydraulic variables such as standard deviation of flow velocity, turbulent kinetic energy, Froude number, and shear stress, and compared them with the habitat availability within the river reach. Our results revealed that in a natural flow environment, parr display a high individual variability in habitat preferences in relation to flow turbulence. Such heterogeneous habitat preferences suggest that individuals are not constrained to single habitat types and exhibit flexible habitat use. Furthermore, no differences were observed in habitat preferences between the four daily periods (dawn, day, dusk, and night) within individual parr. [less ▲]

En juillet 2004, le gouvernement fédéral belge lançait un nouveau dispositif d’accompagnement et de contrôle des chômeurs de longue durée. Ce nouveau dispositif allie un renforcement des actions d’accompagnement (aide à la recherche d’emploi et offre de formations) à un système de contrôle basé sur la convocation des chômeurs à un ou plusieurs entretien(s) visant à vérifier et stimuler leur recherche d’emploi, la convocation au premier entretien étant précédée d’une lettre d’avertissement. S’appuyant sur un échantillon de plus de 90.000 demandeurs d’emploi wallons (la région francophone de Belgique), l’objet de ce papier est d’évaluer si ce nouveau dispositif a permis d’améliorer l’accès à l’emploi ou à une formation des chômeurs, par rapport à ce qui ce serait passé en son absence. L’effet du dispositif est évalué au travers de modèles de durée discrets et est estimé par double différence, sur base de l’observation de trajectoires individuelles avant et après la mise en place du dispositif, pour le population cible du dispositif et pour une population de contrôle. Les résultats montrent que le dispositif a eu un effet relatif substantiel, bien que limité en termes absolus, sur l’accès à une formation de la majorité des chômeurs ciblés. Les résultats sont plus décevants en ce qui concerne l’accès à l’emploi, pour lequel une amélioration relativement plus modeste n’est observée que pour une minorité des chômeurs ciblés. [less ▲]

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. [less ▲]

Objective: The aim of our study was to adapt the VHI to the tracheo-oesophageal voice patients and to evaluate its coherence and reproducibility. Method: Firstly, 9 items from the original VHI, identified in a former study as lacking pertinence to the patient group, were rejected. Secondly, the 21 items left were modified and 9 new items were created based on a review of the literature and on the opinion of clinicians. Lastly, following the opinion of laryngectomised patients we created and added another 10 items to the scale, resulting in 39 items. The reliability and reproducibility of this new scale were investigated on a population of 18 laryngectomised patients. Results: The statistical analyses permitted us to reduce the scale to 30 items. The mean scores obtained on the new adapted VHI are respectively 17.7 ± 10.2 (SD) for the functional scale, 11.5 ± 7.1 for the emotional scale, 17.0 ± 7.3 for the physical scale and 46.2 ± 20.4 for the global score. The test-retest correlations for the global score and for the three sub scales are strong and very significant (Global: r = 0.808; F: r = 0.803; E: r = 0.712, P: r = 0.883, p<0.001). The test-retest stability is thus excellent. The results of the tracheo-oesophageal voice subjects on this scale are revealing a moderate impact of their vocal impairment in their daily life.

Organochlorinated compounds such as polychlorobiphenyls (PCB), dichloro-diphenyl-dichloroethylene (DDE) and dichloro-diphenyl-trichloroethane (DDT) have the characteristic to influence the endocrine system of many fish species and mammals and are thus qualified as endocrine disruptors. The objective of this project aims a better understanding of the effects of these compounds on the thyroid function of European seabass (Dicentrarchus labrax). Thyroid tissue and muscle of 46 seabass from the Aegean Sea in Greece (fished and aquaculture, n=15 and n=31, respectively) were sampled. The levels in PCBs, DDT and DDE were evaluated in the muscles of 30 individuals. The diameter of follicles and the epithelial cell heights were measured in each individual by optical microscopy. The concentration of the thyroid hormone T4 (thyroxin) was measured by Radio-Immuno-Assay (RIA). Finally, the potential relationships between these thyroid parameters and these organic compounds were investigated using factor analysis and multiple regressions. A significant relationship between persistent organic pollutants (muscular PCBs and DDT concentration) and the different thyroid parameters (diameters of follicles, epithelial cell heights and muscular T4 levels) could be observed. We cannot exclude the assumption that an endocrine disruption of thyroid gland related to these pollutants could be the origin of the modifications of these thyroid parameters. [less ▲]

Cette compétence se complexifie, au terme des accompagnements, lorsque les futurs enseignants animent des séances d’analyse collective (petits groupes de futurs enseignants) des pratiques d’enseignement des futurs enseignants accompagnés. La conceptualisation des actions professionnelles est l’enjeu de ces séances. Durant celles-ci, les futurs formateurs sont filmés en vue d’analyses réflexives de leur pratique. C’est l’analyse de cette étape de l’apprentissage des futurs formateurs et sa régulation, qui fera l’objet de cette communication. [less ▲]

Carried by the philosophical mainstream, which had built modernity on the primacy of vision, rationalism, which gradually imposed itself as an academic discourse, soon took architecture on the path of abstraction. This finally proved Marshall McLuhan right, who in 1962 was legitimately going to suspect that such a bias must imply “a distortion of reality.” In this critical context and with globalisation as a backdrop, Kenneth Frampton will try to evaluate the points of resistance on which a dialectical approach could be based that might lead us out of the double dead-end of regionalism and modernism, with the sense of touch playing a crucial part. In this paper we will briefly consider how this issue was raised and particularly emphasize the prospects that a phenomenology of touch (which, according to the Livre blanc published in 2004 by the Institut de la Cambre does frighten our contemporaries) can offer to architecture and to the teaching thereof.

Mon intention est d’examiner quelques aspects de l’interprétation husserlienne du jugement existentiel. Je tenterai plus exactement de resituer cette interprétation dans une certaine tradition qui s’étend, grosso modo, de Hermann Lotze à Alexander Pfänder. Lotze, rétrospectivement, semble en effet avoir attiré l’attention sur un point que Brentano aurait omis de prendre en compte dans sa théorie du jugement existentiel, à savoir le caractère relatif de la plupart des positions d’existence. Historiquement parlant, la première Metaphysik de Lotze (1841) est en effet à l’origine d’une certaine conception d’après laquelle être a un sens relatif et signifie originairement être en relation. Cette conception sera développée plus tard dans la Logik de Christoph Sigwart (1873) et, surtout, dans les ouvrages de Julius Bergmann (Reine Logik, 1879 ; Sein und Erkennen, 1880 ; Grundprobleme der Logik, 1882). On la retrouve encore – fortement amendée et transformée – dans les cours de logique de Husserl. Dans les développements suivants, je voudrais suggérer que le concept husserlien de « sphère d’existence » fait droit à cette thèse lotzienne – non-brentanienne – d’une « relativité » des positions d’existence, tout en évitant un certain nombre de problèmes qui demeuraient irrésolus dans les interprétations de ses prédécesseurs.

In divided societies, such as Belgium and Canada, the federal principle and consociational power-sharing have been implemented in order to accommodate ethno-linguistic communities. The combination of Daniel Elazar’s seminal work on federalism in plural societies and of Arend Lijphart’s on consociationalism offers a theoretical framework which can be usefully applied to study the distribution of power between the two main ethno-linguistic communities at the highest level of the state. Using the existing “model of points” and the author’s own “model of the weight of ministerial portfolios”, this paper explores the linguistic composition of the federal governments in both countries over the last thirty years (1970-2006). Whereas the Belgian Constitution has required since 1970 that the federal cabinet be staffed by an equal number of Flemish and Francophone ministers, the Canadian Constitution does not require such a linguistic parity and therefore leaves a greater freedom for the composition of the government. On this background, two logics may explain the linguistic composition in the two cases: a logic of transaction between the two main communities and a logic of representation. The paper opens, on the one hand, with the elaboration of the theoretical framework combining the works of Elazar and Lijphart and, on the other hand, with the construction of the two models. The framework and the models are applied to each case, emphasizing the logic of transaction and the logic of representation. On the basis of this examination, this paper concludes by suggesting that Flemish and Francophone Belgians as well and English and French Canadians benefit from the composition of the federal cabinet. The conclusion opens—new—ways and means to hinder political tensions in plural societies through the institutional arrangement. [less ▲]

The aim of this paper is to shed light, in an exploratory manner, on the role of the choices made in terms of governance in reorganisation projects initiated on territories affected by companies' restructuring. Actor-network theory is used to analyse the dynamics present on three territories concerned by the restructuring of a same company. It allows to identify the strengths and weaknesses of the territorial reorganisation's modes of management and to highlight their decisive influence on the evolution of the projects. [less ▲]

As many manufacturing techniques, microfabrication methods possess limitations. Consequently, manufacturing constraints have to be considered during microsystems design process. Therefore, the direct use of automatic design tools like topology optimization is not possible. For instance, optimal topologies generally contain closed cavities that cannot be produced using the usual microfabrication techniques like layer deposition. The present paper intends to add a layer deposition constraint to the optimization problem using recent developments of CONLIN software. However, with this new optimization procedure we could observe that classical sensitivities filtering makes optimization problem rather unstable while filtering the density field itself keeps good convergence properties.

The aim of this paper is to gather the findings from the multiple studies focused on the identification of failure paths, in order to propose an unifying model showing the chronological combination of the diverse factors leading a company to bankruptcy. An in-depth analysis of the existing literature and of its limitations leads to the elaboration of an original model presenting the different phases through which a company goes by in its evolution towards its juridical failure. Moreover this model emphasizes the fact that all companies do not follow the same paths before they disappear (Argenti, 1976). [less ▲]

Stress at work has become a major problematic in Europe this last decade. Several methods for diagnosis and intervention can be listed. In this context, an examination of interventions taking place in companies is necessary: what are the reasons for implementing stress prevention programmes (SPP)? Which ones are the most frequent? What are the success and failure factors for implementing SPP? In order to answer those questions, a large scale survey was implemented in Belgian companies (N=210). Results show that a) companies mainly use diagnosis to fulfil legal obligation, b) psychosocial risk assessments are less implemented in small companies (less than 50 workers), c) interventions are rarely systematically evaluated, d) most interventions target work environment, and specifically organisational (rather than ergonomic) outcomes, and e) communication/participation and methodological outcomes facilitate implementation of intervention, whereas changes and time/finances outcomes are blocking factors. To conclude, we can say that our survey emphasizes the relevance of public-awareness campaign (particularly towards small companies) about the necessity of implementing stress prevention program and of proceeding to systematic evaluation of such program. Public-awareness campaign is also needed concerning the impact of facilitating outcomes such as communication, participation and methodology, and of blocking outcomes such as organizational changes, time constraints and costs. Theoretically speaking, our study stresses first the prevalence of work-related interventions that are organisational rather than ergonomic or individual. Another point rather new regarding the existing literature is the blocking aspect of organizational changes. [less ▲]
