In the 21 st decade, nanotechnology is back bone of research. Thesenanoparticles have special attention in the all area of world. The particlestructures manipulation rang from 1-100nm and has high properties canbe synthesis by different methods.…

Ce travail a pour but d’étudier le comportement des composants de la chaîne photovoltaïque. Le type de convertisseur, utilisé dans le système, est un hacheur élévateur. Les méthodes de poursuite du point de puissance maximale ‘MPPT’ sélectionnées…

L’efficacité de la production de l’énergie solaire photovoltaïque (PV) dépend essentiellement des conditions auxquelles est soumis le générateur photovoltaïque. Ces conditions peuvent être environnementales, opérationnelles liées au processus de…

In this work, we study a nonlinear inverse problem for an elliptic partial differential equation known as the Calderón problem or the inverse conductivity problem. We give a short survey on the reconstruction question of conductivity from…

The removal of two different heavy metals in aqueous solutions was investigated with polyamide nanofiltration membrane SNTENF270-2540, the results show that the retention of iron ions was total (100%). Depending of the experimental conditions, the…

In recent years, Togo's protected areas have been subject to a worrying process of anthropisation. This has led to a decline in forest ecosystems, their biodiversity and their functions. The general objective of this study is to assess the state of…
