A solar cooling plant: a benchmark for hybrid systems control
This paper describes the hybrid model of a solar cooling plant. This modelconsiders all possible operating modes of the process, which are modelled as a nitestate machine whose transition conditions are given by the discrete variables. Thediscrete variables are the electrovalves and pumps. The model has been written as amixed logical dynamical system and is simulated using State ow/Simulink Matlab.The model has been validated using real data from the plant. This plant is being usedas a benchmark for hybrid control experiences by many European researchers in theframework of the HYCON Network of ExcellenceUniĂłn Europea HYCON(FP6-511368

Place et contrat institutionnels des discussions à visée philosophique pratiquées à l'école primaire
International audienceL'article interroge la place des pratiques effectives de discussion à visée philosophique à l'école primaire. Sur la base de quinze années d'études des discussions, et à partir d'échanges enseignants-élÚves retranscrits, l'article montre en quoi ces dispositifs permettent de travailler un contrat de communication à la fois inédit et clairement situé parmi les oraux scolaires. La réflexion des sciences humaines et sociales sur ce genre de discussions scolaires comme la question épineuse d'une institutionnalisation, en termes d'avantage vs désavantage au regard des pratiques actuelles, sont avancées
Les braséros tripodes à Mégara Hyblaea : analyses typologiques et archéométriques
Few fire places were discovered in the houses of Megara Hyblaea. On the contrary, tripod braziers were quite numerous and their use in the kitchen seems probable. Their forms are untraditional and two very different types can be distinguished. Petrographic analyses allowed the identification of four main groups of fabrication. The majority of the ceramics studied appears to be imported, possibly from northeastern Sicily and the Aegean
Human Tâcell lymphotrophic virus in solidâorgan transplant recipients: Guidelines from the American society of transplantation infectious diseases community of practice
These updated guidelines from the Infectious Diseases Community of Practice of the American Society of Transplantation review the diagnosis, prevention, and management of Human Tâcell lymphotrophic virus 1 (HTLV)â1 in the preâ and postâtransplant period. HTLVâ1 is an oncogenic human retrovirus rare in North America but endemic in the Caribbean and parts of Africa, South America, Asia, and Oceania. While most infected persons do not develop disease, <5% will develop adult Tâcell leukemia/lymphoma or neurological disease. No proven antiviral treatment for established HTLVâ1 infection is available. The effect of immunosuppression on the development of HTLVâ1âassociated disease in asymptomatically infected recipients is not well characterized, and HTLVâ1âinfected individuals should be counseled that immunosuppression may increase the risk of developing HTLVâ1âassociated disease and they should be monitored postâtransplant for HTLVâ1âassociated disease. Currently approved screening assays do not distinguish between HTLVâ1 and HTLVâ2, and routine screening of deceased donors without risk factors in low seroprevalence areas is likely to result in significant organ wastage and is not recommended. Targeted screening of donors with risk factors for HTLVâ1 infection and of living donors (as time is available to perform confirmatory tests) is reasonable.Peer Reviewedhttps://deepblue.lib.umich.edu/bitstream/2027.42/151899/1/ctr13575.pdfhttps://deepblue.lib.umich.edu/bitstream/2027.42/151899/2/ctr13575_am.pd
