Perspective studies predicting the disease are based on the genetic approaches emerging from the nucleotide polymorphism analysis in different loci through the entire genome in AD patients. Considerable diversity of genes located in these regions raise the question of this diversity's peculiar role in the disease development. The mechanisms of AD have been shown to be associated with the gene variation, increased beta-amyloid production and concomitant epileptiform activity/epilepsy in particular (Palop and Mucke, 2009).展开更多

However, this locality has significant photovoltaic energy potential. Nevertheless, the evaluation of the electrical performance showed the dependence of the population on these fluctuations, which could be bypassed or suppressed. In most cases, the blackout occurs during high energy demand. In this paper, a method for evaluating electrical efficiency is proposed and its credibility has been demonstrated on the one hand, and on the other hand, a renewable energy production system is proposed. The Homer software has made possible the analysis of the proposed system and its impact on the environment has also been carried out. The techno-economic study of the system has proved that a solar photovoltaic farm associated with an energy storage system, with a capacity of 47 MW, can meet the energy demand of the town of Maroua. This alternative is profitable for this locality which lives in a precarious situation and a continuous need.展开更多
