The acceptance of Electric and Hybrid Electric Vehicle is related to their eco-efficiency, i.e. their ability to both reduce environmental impact while also providing a sufficient user satisfaction. The objective of this study is to provide a rationale design tool based on a multidisciplinary optimization approach to support the design of hybrid electric powertrain to simultaneously maximize user satisfaction complex criteria and minimize the Eco-score. In order to carry out the optimization problem efficiently the approach makes use of metamodeling techniques in order to save computation time in the optimization process that is driven by a Genetic Algorithm. The approach is applied to highlight the effect of different energy storage systems (batteries v.s. ultra capacitors) upon the optimized HEV design taking care of both Eco-score and User satisfaction. In the selected application that is a heavy urban bus with a mild hydrid electric powertrain, the ultra capacitors are slightly superior to NiMH batteries when emphasizing the Ecoscore criterion.

Background: Necrotising enterocolitis (NEC) is a major cause of mortality and morbidity in very low birth weight (VLBW) preterms. Pathogenesis remains unclear. Recently, we observed a few NEC occurring within the 48 h following prophylactic administration of intravenous immunoglobulin (IVIgG). The aim of the present study was to evaluate the influence of IVIgG administration on the incidence of NEC in our neonatal intensive care unit (NICU). [less ▲]

Introduction Intramedullary cavernous angiomas (ImCA) of the spinal cord are very uncommon malformations especially in the pediatric population where only ten cases have yet been reported within the available literature. Case report In this paper, the authors report the case of a 12- year-old girl presenting with a T11 level hematomyelia because of a cavernous angioma. Microsurgical excision was performed with good clinical outcome and no magnetic resonance imaging evidence of residual cavernoma 30months later. Discussion Despite the small number of cases reported in children, this one contributes to the literature identifying special features of presentation and management of ImCA for pediatric patients. Because a higher risk of recurrent bleeding has been demonstrated for ImCA, with dramatic clinical consequences, microsurgical removal remains the only definitive treatment. [less ▲]

Vagile invertebrates are regarded as key-components of Posidonia oceanica meadow ecosystems, particularly in organic matter transfers from primary producers to higher level consumers. Among these invertebrates, amphipod crustaceans are one of the most abundant and diverse groups, and probably play an important role in meadow ecosystem functioning. However, their trophic ecology is poorly known, and these crustaceans are generally regarded as vegetal epiphytes consumers or generalist detritivores, due to the lack of accurate studies. Here, we focused on the study of the interspecific trophic diversity, and on the importance of other food sources (Posidonia leaves and litter, animal epiphytes, suspended particular organic matter, …) in those amphipods’ diet. To assess these phenomena, we used stable isotopes ratios of carbon and nitrogen as trophic tracers. It appears that, while some species (such as Apherusa chiereghinii and Aora spinicornis) seem to feed mainly on epiphytes, others, like Dexamine spiniventris, exploit different food sources. These results thus tend to show that amphipod trophic diversity could have been underestimated in the past. Moreover, they enhance the comprehension of the feeding ecology of these animals, and therefore of the way they interact with the Posidonia meadow ecosystem. [less ▲]

Abstract Background: Although screening programs for chronic kidney disease (CKD) may be of great value, these programs are not yet implemented in the Democratic Republic of Congo. This study focused on proteinuria and examined its prevalence in terms of the number needed to screen for the different risk factors of CKD. Such knowledge would guide the utility of population screening to prevent end-stage renal disease. Methods: A cross-sectional survey was conducted in Kinshasa on the Second World Kidney Day. A sample of 3,018 subjects was interviewed and the following measurements were performed: blood pressure, body mass index, glycemia and urine protein. Logistic regression analysis was used to identify determinants of proteinuria. Results: The prevalence of proteinuria was 17.1% (95% CI 15.8–18.6). Other CKD risk factors identified were: hypertension, diabetes mellitus, obesity and metabolic syndrome. To identify 1 case of proteinuria, one would need to screen 4 persons with dia-betes, 5 persons with hypertension, 4 subjects having metabolic syndrome, 5 persons aged 6 72 years and 9 persons without any of the conditions mentioned above. Age, overweight and diabetes were the strongest factors associated with proteinuria. Conclusions: This study indicates that proteinuria and traditional risk factors for CKD are very prevalent in Kinshasa. Realistic policies to stem these conditions should be a public health priority.

Polychlorinated biphenyls (PCBs) and organochlorine pesticides like Dichloro-Diphenyl-Trichloroethane (DDTs), Hexachlorocyclohexanes (HCHs), Aldrin and Dieldrin were analysed in the muscle of sea bass (Dicentrarchus labrax) sampled in coastal regions near several important European river mouths (Garonne, Charente, Loire, Seine and Scheldt). These organochlorinated compounds are known to influence the endocrine system of many fish species and mammals and are thus qualified as endocrine disrupters. To highlight a potentially harmful effect of these compounds on the thyroid function of these fishes, we measured the muscular concentrations of thyroid hormones T3 and T4 by Radio-Immuno-Assay. The contamination levels were as follows: the highest concentrations were measured in individuals collected from the coastal region near the Scheldt > Seine > Loire > Charente and the lowest levels were observed in sea bass from coastal regions near the Garonne (from 2422 to 6188 ng.g-1 lw). The measured levels were generally higher than those reported in literature in sea bass from other regions in the Mediterranean Sea. Contamination patterns were different depending on the sampling area and thus the river input of pollutants. The multivariate statistical analysis revealed a significant relationship between the measured persistent organic pollutants and thyroid hormones in muscle. We cannot exclude the assumption that an endocrine disruption of the thyroid related to these pollutants could be the origin of these modifications of the thyroid hormone concentrations. [less ▲]
