The CoRoT satellite is revolutionizing the photometric study of massive O-type and B-type stars. During its long runs, CoRoT observed the entire main sequence B star domain, from typical hot β Cep stars, via cooler hybrid p- and g-mode pulsators to the SPB stars near the edge of the instability strip. CoRoT lowers the sensitivity barrier from the typical mmag-precision reached from the ground, to the μmag-level reached from space. Within the wealth of detected and identified pulsation modes, relations have been found in the form of multiplets, combination of frequencies, and frequency- and period spacings. This wealth of observational evidence is finally providing strong constraints to test current models of the internal structure and pulsations of hot stars. Aside from the expected opacity driven modes with infinite lifetime, other unexpected types of variability are detected in massive stars, such as modes of stochastic nature. The simultaneous observation of all these light curve characteristics implies a challenge for both observational asteroseismology and stellar modelling. The CoRoT space mission was developed and is operated by the French space agency CNES, with participation of ESA's RSSD and Science Programmes, Austria, Belgium, Brazil, Germany, and Spain. [less ▲]

Spurred by the spectroscopic and interferometric observations of rapidly rotating stars and the highly accurate pulsation data coming from asteroseismology space missions, theoreticians have spent many years developing models for such stars and studying their oscillations. This has led to the discovery of new phenomena and new types of pulsation modes. In what follows, a review is given of the different methods used to model the effects of rotation on stellar pulsations, as well as a description of these effects on inertial, gravito-inertial, r and acoustic modes.

The environments of both hot and cool stars are the sites of highly dynamic processes involving motion of gas and plasma in winds, flows across shocks, plasma motions in closed magnetic fields, or streams along magnetospheric accretion funnels. X-ray spectroscopy has opened new windows toward the study of these processes. Kinematics are evident in line shifts and line broadening, and also more indirectly through the analysis and interpretation of density-sensitive lines. In hot stellar winds, expanding-wind kinematics are directly seen in broadened lines although the broadening has turned out to often be smaller than anticipated, and some lines are so narrow that coronal models have been revived. Although X-ray spectra of cool stars have shown line shifts and broadening due to the kinematics of the entire corona, e.g., in binary systems, intrinsic mass motions are challenging to observe at the presently available resolution. Much indirect evidence for mass motion in magnetic coronae is nevertheless available. And finally, spectral diagnostics has also led to a new picture of X-ray production in accreting pre-main sequence stars where massive accretion flows collide with the photospheric gas, producing shocks in which gas is heated to high temperatures. We summarize evidence for the above mechanisms based on spectroscopic data from XMM-Newton and Chandra. [less ▲]

The CoRoT space observatory is a project which is led by the French space agency CNES and leading space research institutes in Austria, Brazil, Belgium, Germany and Spain and also the European Space Agency ESA. CoRoT observed since its launch in December 27, 2006 about 100 000 stars for the exoplanet channel, during 150 days uninterrupted high-precision photometry. Since the The CoRoT-team has several exoplanet candidates which are currently analyzed under its study, we report here the discoveries of nine exoplanets which were observed by CoRoT. Discovered exoplanets such as CoRoT-3b populate the brown dwarf desert and close the gap of measured physical properties between usual gas giants and very low mass stars. CoRoT discoveries extended the known range of planet masses down to about 4.8 Earth-masses (CoRoT-7b) and up to 21 Jupiter masses (CoRoT-3b), the radii to about 1.68 × 0.09 R [SUB]Earth[/SUB] (CoRoT-7b) and up to the most inflated hot Jupiter with 1.49 × 0.09 R [SUB]Earth[/SUB] found so far (CoRoT-1b), and the transiting exoplanet with the longest period of 95.274 days (CoRoT-9b). Giant exoplanets have been detected at low metallicity, rapidly rotating and active, spotted stars. Two CoRoT planets have host stars with the lowest content of heavy elements known to show a transit hinting towards a different planethost-star-metallicity relation then the one found by radial-velocity search programs. Finally the properties of the CoRoT-7b prove that rocky planets with a density close to Earth exist outside the Solar System. Finally the detection of the secondary transit of CoRoT-1b at a sensitivity level of 10[SUP]-5[/SUP] and the very clear detection of the "super-Earth" CoRoT-7b at 3.5 × 10[SUP]-4[/SUP] relative flux are promising evidence that the space observatory is being able to detect even smaller exoplanets with the size of the Earth.

This paper gets together palynological informations issued from 34 sites from Atlantic West Africa for making, with the aid of an exhaustive bibliography, the synthesis of the palaeoecological evolution of the area during the last 20 000 years. From the collected data, the following progressive process was established: the period going from 20 000 to 15 500 yrs BP, characterized by a maximum of aridity, is marked by an important expansion of savannahs. During the post-glacial transition, between 15 500 and 12 000 yrs BP, an increase of heat and moisture results in the renewal of the Guineo-Congolese rainforest in the lowlands and of the afro-mountainous forest in the highlands. From 8000 to 6000 yrs BP, a wet and warm optimum favours the rise of lakes levels and a wide forests’ expansion. Then, a major change of gradual climatic drying out, recorded towards 4000 yrs BP and extended until 2500 yrs BP allows the retreat of forests and the opening of some clumps. From 2500 yrs BP, the climate evolves gradually towards its current stage, with warmer and wetter characters but it presents a certain instability in touch with the global changes of the last two millennia. Human influence on environment in Atlantic West Africa increases principally from 2000 yrs BP interfering during the last millennium with climate-related events, de effects of which it can mask.

In ancient Greece, the representation of the divine and heroic world is characterised by a very sophisticated anthropomorphism. However, the suprahuman world is more than the lifelike projection of a human society into a higher sphere. In the discrepancies between socio-history and representation, some aspects of a divine specificity can be discerned. Accordingly, the respective roles of mother and wet nurse are not human types transported as such in the society of Greek gods. These types of human experience are “translated” at a higher level to suggest some aspects of the relationship that men want to establish with their gods. In return – and taking into account the discrepancies mentioned above – the narrative plots that feature such roles among the gods and heroes can reflect on their human counterparts and some current practices within Greek society. This paper addresses the role of the wet nurse respectively endorsed by the goddess Demeter taking care of a human baby and by the goddess Hera suckling the hero Heracles. [less ▲]

Le but de cet ouvrage multidisciplinaire et collectif est, d’une part, de mesurer le degré de concordance – ou de discordance – entre les opinions du public et les décisions politiques en matière de PESD et, d’autre part, de proposer des mesures « pédagogiques » concrètes pour mieux informer les citoyens des enjeux de cette politique. Il a donc pour modeste ambition d’analyser les demandes et les soutiens des opinions publiques européennes en matière de PESD et de voir dans quelle mesure la boucle de rétroaction dans ce domaine pourrait être améliorée pour mieux convaincre ces opinions publiques de l’importance de la PESD pour l’avenir de l’Union. Il s’agira, dans une première partie, de présenter les acteurs principaux de la PESD dans leur rapport aux publics généraux et spécialisés (Sous-commission sécurité-défense du Parlement européen, Assemblée parlementaire de l’UEO, Collège européen de sécurité et de défense, Institut d’Etudes de sécurité de l’UE, organisation de l’ « Erasmus militaire ») ainsi que certaines études de cas sur les élites face aux Eurobaromètres, think tanks français et PESD et acteur national face à la PESD (Parlement belge). Dans une deuxième partie, nous aborderons les sondages d’opinion autour de la PESD, les enseignements des Eurobaromètres, le poids des opinions publiques françaises, britanniques et françaises face à cette politique sectorielle européenne, parallèlement à plusieurs contributions autour de la presse écrite belge, française, britannique et allemande sur la même thématique. Nous terminerons cette partie par la mesure de l’opinion de publics spécialisés sur la PESD à partir d’un sondage effectué auprès d’élèves de l’Ecole Spéciale Militaire de St Cyr (France), de la Nederlandse Defensie Academie de Breda (Pays-Bas) et de l’Ecole royale militaire (Belgique), les futurs officiers des ces trois armées. L’examen des opinions de publics spécialisés, en l’occurrence les futures officiers d’armées européennes, concernant la PESD permet d’appréhender la maîtrise de cette matière et ainsi d’améliorer l’information et de la communication dans ce domaine. Dans la mesure où ces publics sont les premiers concernés par les missions de gestion de crise de l’Union européenne, leur connaissance de cette politique est quelque chose d’important. Qui plus est, les réponses des élèves de ces écoles militaires sont des révélateurs puissants de la « pénétration » des matières européennes autant que des cultures nationales. Dans la mesure où plusieurs des questions posées lors de cette enquête provenaient de la série des Eurobaromètres, enquêtes réalisées pour le secteur Analyse de l'opinion publique de la Commission européenne auprès d’échantillons représentatifs de la population des différents Etats-membres de l’Union européenne, on essaiera de comparer, là où c’est possible et pertinent, les opinions des futurs officiers belges, français et néerlandais à celles de leurs opinions publiques nationales respectives. Il ne s’agira toutefois que de comparaisons très approximatives, dans la mesure où ni les méthodes utilisées (questionnaires écrits d’un côté et face-à-face de l’autre), ni les périodes de collecte des données ne sont les mêmes ; ces comparaisons nous permettront néanmoins de voir si, au niveau de leurs perceptions de la politique européenne de sécurité et de défense, nos publics spécialisés se démarquent ou non, systématiquement et de manière importante, des publics non spécialisés. Nous pourrons aussi examiner quelles sont les préférences de ces publics en matière de PESD, leur degré d’assimilation, le poids du cadre national et dans quelle mesure ils partagent l’objectif d’une plus grande intégration dans ce domaine. Au vu du processus de différenciation sociale à l’œuvre dans nos sociétés, à côté de cette opinion publique indifférenciée, sont en effet apparus et jouent un rôle de plus en plus important des « publics » plus spécialisés, constitués de groupes/catégories sociales ou professionnelles plus directement concernés et/ou intéressés par un domaine politique particulier. Dans la mesure où ce sont eux/elles qui seront, en partie, chargé(es) de donner corps à la PESD, un des groupes les plus directement concernés est évidemment constitué des militaires des différents pays de l’Union européenne, et en particulier des officiers. Ces derniers ayant un niveau d’instruction plus élevé, étant plus concernés et ayant, de par leur profession, une connaissance a priori plus grande de ce domaine que l’opinion publique générale, on peut s’attendre à qu’ils aient également des opinions plus structurées sur la PESD en général et sur ces différents aspects en particulier. Enfin, dans une troisième partie, sur base de ce diagnostic, l’ouvrage tentera de déterminer les axes autour desquels les efforts d’information devraient être portés afin de favoriser le développement d’une identité collective européenne de sécurité et de défense. Cette identité est d’importance dès qu’il s’agit de faire assimiler les objectifs de la Stratégie européenne de sécurité et la Politique européenne de sécurité et de défense . Du point de vue méthodologique, une combinaison de méthodes, quantitatives (réalisation de sondages auprès de publics spécialisés et analyses secondaires de sondages d’opinions européens et nationaux), qualitatives (analyses de contenu des médias, des débats parlementaires, etc.) et études de cas, a ainsi été utilisée pour générer une connaissance empirique de ce domaine, des différents types d’opinion publique (« grand public » et publics spécialisés), et de la manière dont l’information du public est produite et délivrée. Sur base de ces données, des propositions concrètes en vue d’améliorer le développement d’une identité européenne en matière de sécurité et de défense et ainsi de réduire le « déficit démocratique » dans le domaine de la PESD pourront être avancées. En cela, cet ouvrage peut apporter son concours comme aide au processus de décision autant qu’apport à la connaissance des opinions publiques sur la matière de sécurité et de défense européenne, dans les limites des contraintes de la confidentialité dans le champ intergouvernemental, de l’incapacité de l’opinion publique à se représenter la globalité des enjeux et du caractère éminemment délicat d’un domaine au conséquences parfois létales.

OBJECTIVE: In this study, we have evaluated the organ procurement and transplantation activity from donors after cardiac death (DCD) at our institution over an 8-year period. Our aim was to determine whether this program influenced transplantation programs, or donation after brain death (DBD) activity. METHODS: We prospectively collected our procurement and transplantation statistics in a database for retrospective review. RESULTS: We observed an increasing trend in potential and actual DCD number. The mean conversion rate turning potential into effective donors was 58.1%. DCD accounted for 16.6% of the deceased donor (DD) pool over 8 years. The mean age for effective DCD donors was 53.9 years (range, 3-79). Among the effective donors, 63.3% (n = 31) came from the transplant center and 36.7% (n = 18) were referred from collaborative hospitals. All donors were Maastricht III category. The number of kidney and liver transplants using DCD sources tended to increase. DCD kidney transplants represented 10.8% of the DD kidney pool and DCD liver transplants made up 13.9% of the DD liver pool over 8 years. The DBD program activity increased in the same time period. In 2009, 17 DCD and 33 DBD procurements were performed in a region with a little >1 million inhabitants. CONCLUSION: The establishment of a DCD program in our institution enlarged the donor pool and did not compromise the development of the DBD program. In our experience, DCD are a valuable source for abdominal organ transplantation. [less ▲]

INTRODUCTION: End-stage renal disease is a major public health problem in Viet Nam. A cooperative project between the University of Liege, Belgium, and the University of Medicine Pham Ngoc Thach, Ho Chi Minh City, Viet Nam, has permitted the establishment of an autonomous program of renal transplantation from living-related donors at the Peoples' Hospital No 115. The aim of this paper was to report the primary results of the project and to draw conclusions for the future. PATIENTS AND METHODS: From January 2004 to July 2008, we performed 33 living-related renal transplantations. Mean ages of donors and recipients were 31.8 +/- 9.5 and 41.6 +/- 13.5 years, respectively. Laparoscopic nephrectomy was performed in 6 donors. The immunosuppressive regimen consisted of three drugs associated with induction therapy using anti-interleukin-2 receptor monoclonal antibody. RESULTS: The 33 donors are in good health at follow-up. Four developed major intra- or postoperative hemorrhage necessitating transfusion, with a surgical re-exploration in 1 donor. Wound infection occurred in 2 donors. Posttransplant recipient and graft survivals at 1 versus 3 years were 82% and 73% versus 82% and 65%, respectively. Eight recipients presented 13 biopsy-proven acute rejection episodes that were reversible in 7, but 1 patient lost his graft due to an irreversible rejection. Two recipients developed cancer. CONCLUSIONS: These initial results have encouraged us to continue the program of renal transplantation from living-related donors. However, they also pointed out the need to develop other donor sources. [less ▲]

In this paper, we propose a technique based on 3D information (also called depth or range) for the detection of humans. First, a background subtraction technique operates to detect the silhouettes of humans and objects moving in the scene. Then, a machine learning algorithm is used to predict if a silhouette annotated with depth matches a human silhouette or not. The complete method is designed to cope with defects introduced during the segmentation step. Results, obtained on computer generated data, show that 3D depth data is a valuable information for detecting humans in that it improves over techniques based on binary silhouettes. In our experiments, we have reached an accuracy of 99.9% thanks to the depth information. [less ▲]
