Design of a Hybrid Photovoltaic Thermal System in Lebanon

Due to global warming and the high toxic gas emissions of traditional power generation methods, renewable energy has become a very active topic in many applications. This study focuses on one versatile type of solar energy: Hybrid Photovoltaic Thermal System (hybrid PV/T). Hybrid PV/T combines both PV and thermal application and by doing this the efficiency of the system will increase by taking advantage of the temperature loss from PV module. The solar radiation and heat will be harnessed to deliver electricity and hot water simultaneously. In the present study a solar system is designed to recycle the heat and improve the temperature loss from PV module in order to supply both electricity and domestic hot water. The project was tested twice in Zouk Mosbeh - Lebanon; on May 18, 2016, and June 7, 2016. The average electrical efficiency was around 11.5% with an average electrical power output of 174.22 W, while with cooling, the average electrical efficiency reaches 11% with a power output of 200 W. The temperature increases by about 7 degrees Celsius from the inlet. The 1D conduction model is also performed in order to design the hybrid PV/T system

Savoirs en action

Dynamiques de citoyenneté, d'éco-citoyenneté, de réseaux, de médias, de territoires, de culture et d'interculturalité. Pratiques journalistiques, innovations numériques, nouvelles formes de savoir, mouvements sociaux et divulgation des sciences… Autant de problématiques et de pratiques que l'approche communicationnelle relient. En croisant les regards théoriques et empiriques, cet ouvrage offre une contribution à la compréhension et à l'analyse des logiques d'actions et de construction des savoirs dans un espace méditerranéen en pleine mutation. Car, depuis près de trois décennies, par vagues successives, les relations scientifiques entre chercheurs en communication du nord et du sud de la Méditerranée ne cessent de s'intensifier. Il semble émerger sinon une identité méditerranéenne contemporaine, du moins des dynamiques et mouvements qui renvoient à un patrimoine commun issu d'une l'histoire millénaire et qui se traduit aujourd'hui dans les paradoxes d'une unité plurielle. Cet ouvrage apporte aussi la preuve que le champ de la communication favorise le dépassement des frontières institutionnelles et académiques, et nourrit une réflexion commune entre chercheurs de l'Université et du CNRS

Predictors of Enteral Autonomy in Children with Intestinal Failure: A Multicenter Cohort Study

ObjectivesIn a large cohort of children with intestinal failure (IF), we sought to determine the cumulative incidence of achieving enteral autonomy and identify patient and institutional characteristics associated with enteral autonomy.Study designA multicenter, retrospective cohort analysis from the Pediatric Intestinal Failure Consortium was performed. IF was defined as severe congenital or acquired gastrointestinal diseases during infancy with dependence on parenteral nutrition (PN) >60 days. Enteral autonomy was defined as PN discontinuation >3 months.ResultsA total of 272 infants were followed for a median (IQR) of 33.5 (16.2-51.5) months. Enteral autonomy was achieved in 118 (43%); 36 (13%) remained PN dependent and 118 (43%) patients died or underwent transplantation. Multivariable analysis identified necrotizing enterocolitis (NEC; OR 2.42, 95% CI 1.33-4.47), care at an IF site without an associated intestinal transplantation program (OR 2.73, 95% CI 1.56-4.78), and an intact ileocecal valve (OR 2.80, 95% CI 1.63-4.83) as independent risk factors for enteral autonomy. A second model (n = 144) that included only patients with intraoperatively measured residual small bowel length found NEC (OR 3.44, 95% CI 1.36-8.71), care at a nonintestinal transplantation center (OR 6.56, 95% CI 2.53-16.98), and residual small bowel length (OR 1.04 cm, 95% CI 1.02-1.06 cm) to be independently associated with enteral autonomy.ConclusionsA substantial proportion of infants with IF can achieve enteral autonomy. Underlying NEC, preserved ileocecal valve, and longer bowel length are associated with achieving enteral autonomy. It is likely that variations in institutional practices and referral patterns also affect outcomes in children with IF
