Comparative Study of Parallel VerticalJunction Solar Cell Photovoltages
Dieme Nf., Sane M., Honadia P. Ab. Aziz, Barro F. Id.
This work aims, through a theoretical study, to make a comparison of three different parallel vertical junction solar cells photovoltages (Si silicon, InAs indium arsenide and GaAs gallium arsenide). For this we have showed the evolution of these voltages with regard to temperature and the collection of the charge carrier velocity. The photovo(...)

Assessment of CH4 and CO2 surface emissions from Polesgo's landfill (Ouagadougou, Burkina Faso) based on static chamber method
Kayaba Haro, Issoufou Ouarma, Bernard Nana, Antoine Bere, Guy Christian Tubreoumya, Sié Zacharie Kam, Patricia Laville, Benjamin Loubet, Jean Koulidiati
Methane (CH4) and carbon dioxide (CO2) surface emissions from Polesgo's landfill (Ouagadougou, Burkina Faso) were measured using the static chamber technique in 2017 and 2018. The Polesgo's landfill was composed of four zones: Phase I, II, Phase III, and SP. The surface of Phase I was fully covered and its conditions are better for surface emi(...)

Wild and cultivated biomass supply chain for biofuel production. A comparative study in West Africa
Linda Dominique Fabiola Bambara, Marie Sawadogo. Daniel Roy, Joël Blin, Didier Anciaux, Salifou Koucka Ouiminga
Limited access to energy has led to interest in biofuels in most West African countries where jatropha curcas (Jatropha) has been the most widely studied energy crop. However, due to difficulties in obtaining enough jatropha seed at acceptable costs, Balanites aegyptiaca (B. aegyptiaca) could be an alternative feedstock for biofuel production(...)

Convective drying of onion: modeling of drying kinetics parameters
Aboubakar Compaore, Aditya Putranto, A. O. Dissa, Samuel Ouoba, Romain Rémond, Yann Rogaume, André Zoulalian, Antoine Béré, Jean Koulidiati
Drying is a simultaneous heat and mass transfer processes. Drying kinetics is determined by both internal properties and external drying conditions. In this study, two important drying kinetics parameters of onions i.e. effective water diffusivity and relative activation energy of reaction engineering approach (REA) are determined. The generat(...)
