We present a mid-term report on a project aimed at partially identifying the main modes of pulsation in the rapidly pulsating subdwarf B star PG 1047+003. Using the unique HIT-MS mode on FORS2 at the VLT we obtained ˜3000 spectra spread over 4 consecutive half-nights with a typical sampling rate of 20 s. These will be used to extract monochromatic pulsation amplitudes and phases that can be fit to model predictions in order to determine the degree ℓ of the mode in question. [less ▲]

Hierarchical approaches, where nodes are clustered based on their network distances, have been shown to allow for robust and scalable topology-aware overlays. Moreover, recent research works have shown that cluster-based deployments of Internet Coordinates Systems (ICS), where nodes estimate both intra-cluster and inter-cluster distances, do mitigate the impact of Triangle Inequality Violations (TIVs) on the distance predictions, and hence offer more accurate internet latency estimations. To allow the construction of such useful clusters we propose a self-organized distributed clustering scheme. For better scalability and efficiency, our algorithm uses the coordinates of a subset of nodes, known by running an ICS system, as first approximations of node positions. We designed and evaluated two variants of this algorithm. The first one, based on some cooperation among nodes, aims at reducing the expected time to construct clusters. The second variant, where nodes are selfish, aims at reducing the induced communication overhead. [less ▲]

Since their discovery eleven years ago, short-period pulsating sdB stars have proved their potential for quantitative asteroseismological studies. We have recently updated our astero- seismic diagnostic tools in order to incorporate the effects of stellar rotation on pulsations, assuming various internal rotation laws. It is possible, with these new tools, to determine the internal rotation profile of two short-period pulsating sdB stars residing in close binary systems, namely Feige 48 and PG 1336 -018. They exhibit orbital periods of 9.024 h and 2.424 h respectively, as measured from spectroscopy. For the two stars, we show that spin-orbit synchronism is reached from the surface down to ˜ 0.22 R∗ and 0.55 RxE2x88x97 , respectively. The rotation of deeper layers cannot be inferred with the type of modes p-modes observed in short-period pulsating sdB stars. These results can potentially provide new elements to test tidal friction theories, particularly the angular momentum transport, in close binary systems. [less ▲]

Sarcoidosis is a systemic disease of unknown aetiology characterised by the formation of non caseating epithelioid cell granuloma, which can occur in virtually any organ. The involvement of the heart is an important prognostic factor in sarcoidosis. Early treatment prevents irreversible damage of the heart and seems to be associated with better prognosis. [less ▲]

Un modèle d’installation électrique d’habitation avec une ligne à haute tension est développé avec la méthode "Partial Element Equivalent" (PEEC). Cette étude a pour but de déterminer l’existence des courants et tensions induits dans une maison et d’évaluer leur amplitude. Ensuite, nous caractérisons l’influence d’un réseau d’habitations et du type de prise de terre sur ceux-ci. Cette partie du travail nous permet d’obtenir un ensemble de facteurs influençant le niveau des courants induits. Ce papier montre qu’il est possible de déterminer des configurations pour minimiser ces courants dans un réseau d’habitations. [less ▲]

Frailty in the elderly is an important factor of morbidity, particularly in the setting of surgery. The various pathologies that can lead to a functional decline are well known. The risk of mortality and morbidity should be assessed as a function of the nature of the surgical procedure and of the disease for which it is required; the factors of severity, the predictable duration of the procedure, and the expected blood losses must also be taken into account. The thrombo-embolic risk should finally be considered. In the elderly, one may say that the functional risk matters more than the vital risk. Frailty must be integrated into the risk assessment; however, further studies are needed to better determine the impact of that new concept. Undoubtedly, the cognitive and nutritional status are of main importance. A better knowledge of the risks should lead to validate specific interventions that could help to prevent surgical complications, shorten the length of hospital stay, and protect the self-sufficiency of the aged.

This article is talking about the first french national campaign on mental health. It deals with the conditions which have led this campaign. Beginning in March 2005, it tries to fight against stigmatization of people suffering from psychic disorders. This campaign gathers four different instigators. The purpose of this article is to speak about french socio-political evolutions during the last years. In particular, users and local councillors’implication is sought by public policies, as there is a psychologization of social intervention, with an increased recognition of targeted populations’ needs. These evolutions are linked with a will to monitor public spendings. Furthermore, an epidemiologic study leads to make stigmatization of psychic disorders’people a public health problematics.

The sensitivity of the potential feedbacks between climate and biogeochemical cycles (BGC) is adressed with the help of LOVECLIM, a global three-dimensional Earth system model of intermediate complexity. Key physical or biogeochemical parameters of LOVECLIM are varied within their range of uncertainty in order to provide an ensemble of parameter sets resulting in contrasted climate and global carbon cycle sensitivities. The selected climate parameter sets lead to a climate sensitivity ranging from 2 to 4°C and a reduction of the Atlantic meridional overturning circulation (MOC) ranging from 20 to 60% after 1 kyr in response to identical external forcings. The key parameters for the carbon cycle were chosen among those with the largest impact on the marine biogeochemical cycle and on the response of atmospheric CO2 to emission scenario. We then analyze the results of freshwater hosing experiments in which both the climate parameters and the BGC parameters are modified. These experiments allow to examine the impact of changes in climate sensitivity and of MOC reduction over the biogeochemical cycles as well as to assess the potential feedback from the carbon cycle onto the climate. A decreasing MOC directly impacts the ocean biogeochemistry. Most of the model setups show a decline in export production although some parameter sets yield reorganisation of the large scale ocean circulation, which leads to different behaviour of the ocean biogeochemistry. The atmospheric carbon is also affected by a decrease of the MOC. While most parameter sets cause a modest increase in atmospheric CO2, consecutive to the decrease of the continental vegetation, some model versions exhibit an amplification of the atmospheric CO2 response to the forcing. The mechanisms leading to the different responses for the different parameter sets are examined and discussed. [less ▲]
