A phenomenological model of lead acid batteries is developed that is then used to construct an estimator for short term charge acceptance. Conceptually, the model is based on a partial differential equation that is discretized for tractability. With observers for the battery current and state of charge, the prediction of the internal states is improved. Since the model is essentially linear, the short term prediction can be implemented in closed form, thus without the need for computationally intensive prediction simulations at each sampling instant. The only nonlinearity, the dependence on temperature, can be incorporated in a linear parameter-varying model. Un modèle phénoménologique des batteries plomb-acide est développé et utilisé pour réaliser un estimateur d’acceptance de charge à court terme. Conceptuellement, le modèle est basé sur une équation différentielle partielle qui est discrétisée pour simplifier. La prédiction des états du modèle est améliorée par l’utilisation d’observateurs du courant et de la charge de la batterie. Comme le modèle est essentiellement linéaire, la prédiction à court terme peut être formulée en forme close. Il n’est donc plus nécessaire d’avoir recours à des simulations complexes à chaque instant d’échantillonnage. La seule dépendance non-linéaire, celle à la température, peut être incorporée dans un modèle linéaire à paramètre variable.

Increase of the sugar content in grape must, and consequently, alcohol levels in wine are some of the principal problems affecting the winemaking industry. High alcohol content can compromise wine quality, creating sensory imbalances, as well as decreasing the perception of some flavors. The technological approaches proposed at this aim, although allowing achievement of the purpose, can determine negative influence on quality of wine. A promising strategy is based on the use of specific microorganisms, such as selected yeast strains, mainly non-Saccharomyces, able to convert grape must sugars towards secondary metabolites rather than ethanol. This study aims at screening of wild non-Saccharomyces strains in order to identify those suitable for the use in mixed starter for the production of wine with reduced alcohol content and, at the same time, with improved aromatic characteristics.

Solubility experiments were performed on a trachyte and a pantellerite from Pantelleria. The trachyte has $\mathrm{SiO}_{2}=65.2$ wt%, $\mathrm{Al}_{2}\mathrm{O}_{3}=15.2$ wt% and a peralkaline index $(\mathrm{P.I.} = \mathrm{molar}[(\mathrm{Na}_{2}\mathrm{O}+ \mathrm{K}_{2}\mathrm{O})/\mathrm{Al}_{2}\mathrm{O}_{3}]) \sim 1$ while the pantellerite has $\mathrm{SiO}_{2}=72.2$ wt%, $\mathrm{Al}_{2}\mathrm{O}_{3}=11$ wt% and a $\mathrm{P.I.}=1.3$. Solubility experiments were performed in the pressure range of 50–300 MPa at ${T}=950~\text{°C}$ for the trachyte and 50–200 MPa at ${T}=850~\text{°C}$ for the pantellerite. The water content of experimental glasses was determined by Karl Fischer titration, elemental analyser and FT–IR spectroscopy. Water content appears similar in both compositions for analogous pressure conditions, varying from ${\sim }2.5$ wt% at 50 MPa to ${\sim }5.8$ at 200 MPa. Comparison of the experimental data with the thermodynamic models shows that the empirical model of Moore et al. [1998] better matches the experimental data for both compositions, while the thermodynamic models of Papale et al. [2006] and Ghiorso and Gualda [2015] tend to overestimate melt water content, probably due to the paucity of peralkaline melt compositions used for calibration. One inference of these new solubility data is on MI-derived depth of felsic reservoirs at Pantelleria which deepens from 2.4 to 3.5 km.

The article reports on the efforts of French historian François Furet who head the School of Advanced Studies in Social Sciences (EHESS) at the Saint-Simon Foundation, for development of the school and conceiving a new policy of development of social science research.

Résumé Les microbiotes bactériens colonisent les différentes cavités du corps humain et remplissent des fonctions essentielles. Ils constituent des écosystèmes complexes dont l’équilibre est constamment déplacé selon les conditions locales et environnementales. Il en résulte des variations de composition pouvant quelquefois évoluer vers des dysbioses, parfois génératrices de processus pathologiques. Les facteurs extérieurs influent particulièrement sur les microbiotes les plus exposés, tels que le microbiote cutané. Du fait des nombreuses pressions médicales et médicamenteuses, l’hôpital constitue un environnement particulier pouvant modifier les écosystèmes bactériens aussi bien à l’échelle individuelle (microbiotes des patients et des soignants) qu’à l’échelle collective (écosystèmes des services). En chirurgie notamment, les multiples pressions antibiotiques, antiseptiques et traumatiques liées à la prise en charge des patients provoquent des perturbations microbiotiques qui semblent importantes à considérer dans la physiopathologie des infections du site opératoire. Summary Human microbiota colonize the different niches of the human body and have essential functions. They correspond to complex ecosystems perpetually balanced by local and environmental conditions. This results in microbiota composition variations that can sometimes evolve toward dysbiosis linked with pathological processes. External factors affect particularly the most exposed microbiota, like skin microbiota. According to the many medical pressures, the hospital constitutes a particular environment, which can modify bacterial ecosystems at both individual (patient and health-care worker microbiota) and collective levels (ecosystems of hospital units). In surgical departments, the multiple aggressions (antibiotic, antiseptic and traumas) related to the management of patients induce some microbiota disturbances that seem important to consider in the pathophysiology of postoperative infections.

The article discusses the ideology of power, merit, and competence. A particular focus is placed on former Governor Sarah Palin and the sociological stakes of her appearance on the political scene. The author explores the social dynamics surrounding individuals placed in high-power situations. Topics include philosopher Edgar Morin, sociologist Max Weber and his book "l'éthique protestante et l'esprit du capitalisme," and Forrest Gump, the character from the film "Forrest Gump."
