To establish which prenatal, birth, and postnatal characteristics mediate the association between maternal educational level and having a child with obesity at five years. This is a sub analysis of a longitudinal study nested in the BMInForma (Bambini Molto In Forma) program. BMInForma is an ongoing public health multilevel intervention started in 2013 to prevent childhood obesity. A cohort of 4835 children born from 1.7.2010 to 31.12.2011 and who received well-health visit at three and five years of age in Reggio Emilia, Italy were included in the study. Maternal and child anthropometric and lifestyle data were linked with routinely collected birth data. A series of simple and multiple mediation analyses were performed. There were 232 (4.8 %) children with obesity at five year visit. Low maternal educational level was significantly associated with children's obesity at 5 years of age (Odds ratio for the total effect 1.8, 95 %CI 1.4 – 2.5), and with almost all prenatal, birth, postnatal and 3-years-old behaviors. Pre-pregnancy overweight and obesity (OW/OB) and hours in front of TV at three years were two significant mediators that explained 32 % of the total effect of maternal educational level on children with obesity at five years of age (Odds ratio for the indirect effect 1.17, 95 %CI 1.10 – 1.24). Nine percent of this effect was evinced through LGA and gestational diabetes (Odds ratio for the indirect effect 1.07, 95 %CI 1.01 – 1.13). Pre-pregnancy OW/OB was the most important mediator of the effect of maternal educational level on childhood obesity at five years. Interventions are needed to increase awareness of unhealthy behaviors in early pregnancy. [ABSTRACT FROM AUTHOR]

Floating Photovoltaic (FPV) modules are installed on water surface to reduce land use. This original solution, potentially deployable on hydropower and aquaculture basins as well, can benefit of enhanced cooling due to the proximity to water. Thanks to this natural effect, FPV modules can work at higher operating efficiencies than ground-based (GPV) modules. However, because of the relatively young age, FPV still requires higher installation costs than GPV. This study investigates the economic competitiveness of GPV and FPV in terms of energy performance and total costs. Different PV system solutions are economically evaluated on the basis of three key figures, namely the capital costs (CAPEX), the operation and maintenance costs (OPEX) and the power generation costs (LCOE). An economic ranking is created based on the comparative analysis of these three key figures. The crucial point in the proposed economic model is that the revenues resulting from the reduced evaporations are considered as well. Every year, indeed, a significant volume of water can be preserved thanks to the shading effect of FPV modules. This water can be used for various purposes, increasing the overall revenues of the FPV system. In addition, the present LCOE calculations also take into account the performance enhancements that could be achieved through the installation of active cooling systems. In light of the expected economy of scale, a sensitivity analysis of the LCOE is carried out to account potential reductions in the capital cost of FPVs. This is done by analyzing the energy and economic performance of various FPV designs on a water basin in Southern Italy. The results demonstrate that, reducing the CAPEX of the FPV by 30 %, a nearly 20 % reduction in LCOE can be obtained compared to the reference GPV system. • Floating photovoltaic systems represent an effective no ground consuming solution. • Fixed and tracked floating solutions with mono and bifacial modules are considered. • The economic comparison also considers the advantages of the aquatic environment. • CAPEX sensitivity analysis shows that most floating solutions are cost effective. • 1 to 10 % CAPEX reduction allows tracked floating to be competitive with ground PV.

p53 codon 72 polymorphism in Italian women have a minor role in determining genetic susceptibility to endometriosis. The racial differences, in association with other risk factors, might be underlined in endometriotic disease.
