Massive stars present the interesting property to generate strong stellar winds. In the particular case of binary systems made of two massive stars, the two stellar winds are likely to collide. In addition, in this scenario, interesting physics is occurring, such as strong high-energy emission, dust production or even particle acceleration. However, our capability to understand these "higher-level" processes relies intimately on our knowledge of stellar and orbital parameters of these binaries, and on our vision of the hydrodynamics that is taking place in these objects. In this context, the purpose of this presentation is to discuss the expected contribution of long baseline interferometry. [less ▲]

Nowadays, progresses in medicine, biotechnology, microelectronic and many other fields are more and more sustained by the development of novel polymer materials with constantly improved properties and well-defined molecular parameters. In this context, we designed a controlled radical polymerization (CRP) technique based on cobalt complexes which is able to efficiently control the radical polymerization of challenging monomers such as vinyl acetate (VAc), N-vinyl pyrrolidone (NVP) and acrylonitrile (AN). This so-called Cobalt-Mediated Radical Polymerization (CMRP) also gave access to unique diblock copolymers by sequential polymerization of the above mentioned monomers. However, addition of isoprene to polymer chains preformed by CMRP did not lead to the expected poly(isoprene) containing copolymers. Instead, the quantitative coupling reaction of the polymer chains was observed, as assessed by the perfect doubling of the molar mass of the initial macromolecules. This result is very exciting because this so-called Isoprene-Assisted Radical Coupling (I-ARC) reaction is not limited to polymers with low molar masses and homopolymers, contrary to the existing radical chains coupling methods. Indeed, when applied to diblock copolymers, IARC constitutes a straightforward approach for the synthesis of telechelic symmetrical ABA triblock copolymers and is thus a very promising tool for macromolecular engineering.

A series of novel fluorinated amphiphilic stabilizers of different architecture (diblock, grafted, or palm tree copolymers) were successfully prepared by reversible addition-fragmentation chain transfer and used as stabilizers for the dispersion polymerization of 2-hydroxyethyl methacrylate (HEMA) in fluorinated solvent, namely alpha,alpha,alpha-trifluorotoluene (TFT). The effect of the amount and the architecture of the copolymer on the size and the stabilization of the particles was studied. Whatever the experimental conditions, scanning electron microscopy showed the formation of submicronic (typically about 300 nm) spherical particles, with a narrow size distribution. The principal difference emerges from the concentration of surfactant. Indeed, at higher copolymer concentration, smaller and less aggregated particles were produced. These results were confirmed by dynamic light scattering but these measurements also revealed the presence of larger aggregates (1,5 micrometer). Furthermore, the surfactant properties of the copolymers were investigated by measuring the interfacial tension at the H2O/TFT interface, and the results were correlated to their stabilizing efficiency in the dispersion polymerization of HEMA.

La gestion des âges sur le marché du travail est devenue depuis quelques années une question centrale, débattue tant au sein du monde politique que scientifique. Elle s’articule autour de différents thèmes dont les principaux sont les modalités de maintien au travail des personnes de plus de 45/50 ans, les relations intergénérationnelles dans l’entreprise et la gestion des compétences à travers les âges (transfert des compétences et tutorat, développement et mise à jour des compétences), implication et motivation au travail. Dans le cadre d’un projet financé par le Fonds Social Européen, nous avons développé un outil d’auto-diagnostic en matière de gestion des âges et des compétences à destination des services des ressources humaines ou des responsables d’entreprises. Cet outil a pour objectif de sensibiliser les entreprises à la gestion des âges et de l’aider à réfléchir aux actions à mettre en place en fonction du diagnostic posé. La première version de cet outil a été testée dans deux entreprises. Cette phase de test nous a permis de mettre à jour une série de questions soulevées par le mise en œuvre d’une politique de gestion des ressources humaines tenant compte de l’âge au regard d’une situation particulière : les métiers en pénurie.

Most of HEV are built using existing engines. These engines have been developed for conventional car and are not especially tailored for HEV. The objectives of this work are to establish general requirements placed on an ICE for a HEV application, to draw the main characteristics of the engine and to find the best configuration of twin-cylinder ICE to motorize an HEV. The twin-cylinder engine offer interesting perspectives in the field of HEV thanks to its small size, low weight and low cost. [less ▲]

Abstract : Poles of competitiveness were launched in Walloon region as a policy for innovation support. This policy aims to reinforce cooperation and partnering between industry and research universities in the region: critical mass, excellence, international size should be reached through the construction of large cooperative projects. Thes new dynamics were in line with the earlier ones which were developed as separate branches of research policy for universities and firms. The governance of the poles, largely controlled by the firms representatives, promoted the development of new forms of interactions between the institutional segments of the Triple Helix of innovation: state – industry – university. Universities stepped quickly in the poles dynamics and took advantage of the opportunity to reinforce their presence in the regional economic framework. Administration was not associated to the launch of the government-defined process and encountered difficulties stepping in the process and entering into these new modes of governance, more supportive than normative. The innovation model at the basis of the policy initiative sets a strong systemic stance to the dynamics of knowledge production but fails to deliver enough reflexivity to go beyond the narrow instrumental rationality of innovation.

Mon intention est de revenir sur un aspect tout à fait particulier du débat entre la phénoménologie et la psychologie de Natorp, à savoir l’écart entre une théorie « statique » et une théorie « génétique » des essences (eidè) ou, pour reprendre l’expression de Natorp, entre un « platonisme statique » et un « platonisme génétique ». Avec cette opposition en tête, j'examine le contentieux qui oppose Reinach à Natorp, à partir de la recension de la "Psychologie générale" rédigée par Reinach. Je focalise mon attention sur les thèses natorpiennes suivantes: (1) Le Je pur est inobjectivable et ne peut être décrit – à quoi Reinach objecte que le Je pur est une donnée phénoménologique, un phänomenologischer Befund; (2) La distinction entre acte et contenu est relative – à quoi Reinach objecte qu’elle est absolue; (3) La distinction entre contenu et objet est également relative – à quoi Reinach objecte que cette distinction est utilisée de façon équivoque mais doit être entendue comme absolue en un sens au moins.

In opposition to traditional machining in which part is manufactured by material removal, rapid prototyping techniques allow parts manufacturing by material addition. The part is built layer-by-layer and the sum of all layers creates the part. Currently, several techniques exist. They use different kind of materials (metals, ceramics, polymers) and technologies (laser melting, laser polymerising, 3D-printing, cladding, ...). Some of these techniques can deal with nanometric particles. In the case of which a near net shape part is built and must be sintered after shaping, the addition of nano-particles can be useful for sintering by increasing specific surface and reactivity of the batch or by improving the properties of the material. An overview about techniques of rapid prototyping allowing the processing of nanomaterials will be discussed. Tests have been done using Optoform process. This process uses a laser to polymerize a paste made of photo-curable resin loaded with powdered material. Nano-particles can be added and stabilized in the paste. In this presentation, the results obtained with both systems Al2O3 + nano Zr02 and SiC + Nano SiC will be discussed. [less ▲]

The main source of atmospheric mineral dust is the Sahara and its desertified margins that produce about half of the yearly global mineral dust. Saharan dust is often transported far away to the sources and causes air quality deterioration impacting northwards the Mediterranean and Europe, westwards crossing the Atlantic Ocean to the United States, the Caribbean and South America, and southwards to the Gulf of Guinea. Saharan dust storms can lead to particulate levels that exceed internationally recommended levels and transport allergens, including bacteria and fungi. Therefore special attention is paid to dust storms as such mineral particulate matter air pollution may be a serious health threat in various regions of the world because it may promote respiratory infection, cardiovascular disease and other ailments.

In various species a relationship between oocyte maturity and morphological characteristics of oocytes has been established. To our knowledge, immature oocyte aspect under light microscopy has been paid little attention in the equine. The aim of the study is to give a general description and analyse microscopic parameters of immature oocytes. Follicles from abattoir ovaries are punctured after measurement of their diameter and their cumulus-oocyte complexes are recovered. Different characters such as oocyte diameter, cumulus aspect, granulosity and polarity of ooplasm are observed under light microscopy. No correlation between estral activity, follicle maturity, cumulus cells aspect, polarity and granulosity of ooplasm was observed. Thickness of zona pellucida differs between oocytes with polar or non polar ooplasm. No correlation was observed between follicle diameter and oocyte diameter and none of the other studied parameters showed an influence on oocyte diameter. Results show that no character of oocytes observed under light microscopy can be related to follicular origin or to any other character. Further studies have to be done to compare these immature oocytes with mature oocytes and to find the ultra-structural origin of characters observed under light microscopy. [less ▲]

L’exploration et le développement d’un champ pétrolier font face à de nom- breuses incertitudes liées aux rendements et aux coûts tout au long du cycle de vie du pro jet. A titre d’exemple les réserves, les investissements, les coûts opératoires, la production et le prix du pétrole sont souvent incertains. En conséquence, Il difficile de prévoir les cash-flows même pour les pro jets pétroliers les plus simples. Différentes méthodes sont disponibles pour aider les décideurs à évaluer les incertitudes, et réduire le risque des opportunités d’investissement en amont pétrolier. La simulation a été reconnue comme un outil d’analyse de risque et de prise de décision en évaluation de pro jets d’investissement en amont pétrolier au début des années 60. Aujourd’hui pra- tiquement toutes les grandes compagnies pétrolières ont incorporé la simulation dans leurs études de pro jets. Dans cet article, nous essayons d’expliquer les critères d’évalua- tion et d’analyse du risque de pro jets d’investissement en amont pétrolier basés sur les cash-flows et de montrer comment la simulation de Monte Carlo peut être utile dans ce cadre.

Deux caractéristiques importantes de l’investissement en exploration ou production pétrolière sont les montants financiers très importants en jeu et les incertitudes élevées. Pour ces raisons, l’analyse du risque devrait être mise en oeuvre dans le processus d’évaluation et de sélection des projets. En fonction de leurs ressources disponibles, les compagnies pétrolières sélectionnent un ensemble de projets sur la base de certains critères : la valeur actuelle nette, le taux de rendement interne, l’indice de profitabilité, etc . . . Cependant, ces critères se révèlent insuffisants vu, d’une part, l’absence de la notion du risque qui est un élément essentiel de l’industrie pétrolière, et d’autre part, l’omission des interactions entre les différents projets. Dans ce travail, afin de pallier aux insuffisances de l’approche traditionnelle, nous appliquons une variante de la méthode de Markowitz afin de déterminer le portefeuille optimal de projets d’exploration ou production qui assure le meilleur compromis risque minimum-rendement maximun sous les diverses contraintes auxquelles l’entreprise est confrontée. Un cas pratique d’application de cette méthode à la sélection de projets d’exploitation pétrolière en Mer du Nord est présenté. Ce cas pratique permet d’illustrer l’influence du facteur prix du brut sur le choix du portefeuille. [less ▲]

Two important characteristics of petroleum exploration and production investment are the high nancial amounts and uncertainties. For these rea- sons, the risk analysis should be implemented in the projects evaluation and the selection process. Depending on their available resources, petroleum companies choose a number of projects on the basis of some criteria: the net present value, internal rate of return, pro tability index However, these criteria appear to be insu cient if we consider, on the one hand, the ab- sence of risk idea which is an essential element of the petroleum industry, on the other hand the omission of the correlations and interactions between di erent projects. In this paper, in order to make up for the lacks of the traditional approach, we apply a variant of Markowitzs method to deter- mine the e cient portfolio exploration and production projects that insure the best compromise minimum risk-maximum return under the di erent constraints faced by the company. A practical application of this method about selection of petroleum exploration projects in the North Sea is pre- sented. This practical case illustrates the in uence of the crude price in the choice of the portfolio. [less ▲]

This work considers the problem of the optimal design of an hydrogen transmission network. This design problem includes the topology determi- nation and the dimensioning problem. We define a solution method that simultaneously looks for the least cost topology of the network and for the optimal diameter of each pipe. These two problems were generally solved separately these last years. The application to the case of development of future hydrogen pipeline networks in France has been conducted on several urban areas. [less ▲]

The B1.5 II-III star HD 180642 is the only known Beta Cephei star in CoRoT’s core programme. To complement the space data of this target, both ground-based photometric and spectroscopic data were collected, to which we added several archival observations. In this talk, we describe our results from a full integration of CoRoT and intensive ground-based observations. The star is a non-linear dominant radial mode pulsator for which low-amplitude modes are detected for the fi rst time. A few of the latter are observed in our ground-based datasets so that a mode identifi cation for them is possible. To this end state-of-the-art techniques are adapted to be applied to a star with a highly non-linear behaviour of the radial mode. Additionally, a careful interpretation of the CoRoT lightcurve helps to identify the wavenumbers. Besides this outcome, the Van Hoof effect for the dominant mode is investigated and the stellar parameters and chemical abundances are determined. All this information is to be used as additional constraints to the CoRoT pulsation frequencies, for asteroseismic modelling of this Beta Cephei star. Additional abstracts cover the lightcurve modelling of this pulsator (Degroote et al.) as well as seismic modelling (Thoul et al.). [less ▲]
