Spectral modelling and especially for massive stars is not a straightforward problem and over the past decades many advances have been made in this field. We now have sophisticated model atmosphere codes that allow to derive the stellar parameters. However, these codes are based on the assumption that the star is single and spherical which is no longer valid for the components of a binary system. On the other hand, observational studies indicate that binarity has an impact on the spectra. This is why we have developed a model called CoMBiSpeC (code of massive binary spectral computation) that specifically accounts for the impact of binarity on the spectra. [less ▲]

The present work presents a model that is composed of a conventional boiler model with a main counterflow gas-water heat exchanger at which a condensing heat exchanger is added. Prior to the second heat exchanger the exhaust gas are converted to equivalent wet air as the wet heat exchanger is simulated by a cooling coil used in air treatment. Six parameters are needed for calculation and these parameters are fitted with experimental data: one test in dry regime and one test in wet regime. Steady-state tests have been performed on two household boilers (a gas-fired and a fuel oil boiler), whose nominal outputs are 24 kW in order to fit the model parameters and check the model behaviour. It seems that the model gives the correct trend for the thermal efficiency prediction. Besides, combustion controls sensors (non nernstian sensors) have been tested by varying the excess of air. In the range tested (from =1.05 to =1.25), the increase in the boiler efficiency is around 1% as the excess of air decreases. However that increase is lower than the measurement uncertainty. The developed model predicts very well that trend. The pollutants emissions have also been measured and the results show that the NOx emissions decrease as the excess air increases. [less ▲]

The objective of this work was to assess the feasibility of a photodiode to control combustion, instead of a spectrometer (which is an expensive sensor to be used in commercial burners). For that purpose, the flame emission has been measured in a hot-water boiler fired with light fuel-oil, whose nominal output power goes up to 370 kW. The parameters investigated were: overall air excess, combustion air distribution, burner power and atmospheric conditions. High influence of air distribution on the flame emission was detected by the diode, since it modifies directly the mixing quality reducing rich-fuel regions where soot can be formed. Low influence of air excess and burner power was found. When these parameters increase, the flame emission decreases. This behavior is explained by the better mixing attained at high burner power and at high air excess. However the high emission level observed at low firing rate can be reduced with a good burner adjustment. With the photodiode, it was possible to find the optimum air excess value where NO, CO and soot are as low as possible. As the photodiode measures locally in the flame, results were compared with images obtained with a CCD camera. Finally, these results are in good agreement with those obtained previously with the spectrometer. [less ▲]

Cette recherche vise à comprendre pourquoi un petit village de montagne du Sud de l'Italie a été colonisé par le pouvoir des organisations mafieuses tout au long du développement d'une démocratie occidentale, comme celle italienne. Pourquoi une communauté de bergers, paysans et artisans s’est transformée, en quelques décennies (des années 60’ aux années 90’ du XXème siècle), en communauté mafieuse, gouvernée par le pouvoir de la camorra et au sein de laquelle des jeunes appartenant aux classes subalternes ont été enrôlés comme « main d’œuvre de la camorra », pour y travailler dans les échelons les plus bas des organisations criminelles? Pour répondre à cette question de recherche j'ai analysé les conditions matérielles de transformation de la communauté qui, comme dans la majorité des régions du Sud de l'Italie, ont incarné les paradigmes du « saccage urbain » et du « vol du territoire », c'est-à-dire une transformation urbanistique violente dirigée par l'envie d'enrichissement des élites (Chiocchi, 1997). Par conséquent, mon attention s'est concentrée sur les processus économiques et politiques modernes qui ont transformé les sociétés du Sud et à travers desquels les mafias se sont imposées, à Montesacro comme dans d'autres villages de l'Italie.

Post-summertime exacerbation of acne is not a rare event. This study was conducted to assess the preventive effect of a proprietary formulation containing 2-hydroxy-5-octanoyl benzoic acid on this environmental related disease. This compound is commonly called beta-lipohydroxyacid (LHA). Among a randomized group of 14 acne-prone women, 12 who developed cornified follicular plugs the end of summertime were treated by the LHA formulation twice daily for 2 weeks. Ten of 14 other women who presented the same skin condition remained untreated as controls. The comedolytic effect was assessed using non-invasive ultraviolet-light video recording combined with computerized image analysis. The cornified follicular plugs were progressively cleared in 10/12 LHA-treated women and in 3/10 untreated volunteers. Analytical assessments showed a significant decrease in both the number and total size of microcomedones in the LHA-treated women. By contrast, no quantitative change was disclosed in the untreated group. It is concluded that the tested LHA formulation exerts comedolytic properties that might help in preventing post-summertime acne exacerbations. [less ▲]

Le saignement vaginal prépubertaire est considéré comme une ménarche isolée lorsque, en l’absence de toute anomalie mise en évidence par les examens médicaux (corps étranger, tumeur, infection…), il n’y pas de développement d’un autre caractère sexuel secondaire. Si d’autres signes pubertaires (thélarche, pubarche, pic de croissance, …) se développent, le saignement vaginal ne sera plus isolé et nous parlerons dès lors de puberté précoce vraie. C’est donc le suivi de la patiente qui nous permettra de faire le diagnostic différentiel entre ménarche précoce isolée bénigne et puberté précoce vraie engageant le pronostic statural et nécessitant une prise en charge spécifique. L’étiologie de la ménarche isolée reste indéterminée et des études complémentaires sont nécessaires. Plusieurs examens complémentaires doivent être réalisés afin d’exclure des pathologies tumorales, infectieuses, traumatiques ou encore hormonales et ceux-ci doivent être répétés lors du suivi de la patiente.

The distant comet 29P/Schwassmann-Wachmann was observed with the HIFI, PACS and SPIRE instruments aboard the Herschel Space Observatory, as part of the guaranteed time key programme "Water and related chemistry in the Solar System" (KP-GT HssO). Supporting observations of the 230 GHz CO line were carried out with the IRAM 30-m telescope. The HIFI observations of the 557 GHz H2O line were performed on 19.05 April 2010, about 2 days after a major outburst, and on 11.02 May 2010, when 29P was in a more quiescent phase. H2O was detected on both dates with a production rate corresponding to about 1/10th the CO production, assuming near-nucleus production. The H2O line shape is consistent with release of water vapour from icy grains. PACS and SPIRE imaging data from 70 to 500 micrometers were acquired mid-June 2010 when the comet was in a quiescent phase. The continuum emission detected in the 70-μm and 160-μm PACS images is weakly extended with respect to the PSF, suggesting a major contribution from the nucleus or from slowly moving large grains.
