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(...)

The Effect of Atmospheric Oxygen on the Puffing and Bursting Phenomena during Vegetable Oils Droplets Vaporization Process for Their Use as Biofuel in Diesel Engine
A. S. Zongo, T. Daho, G. Vaitilingom, B. Piriou, J. Valette, C. Caillol, B. G. Segda, P. Higelin, J. Koulidiati.
The past literature on the use of vegetable oils as fuel in diesel engine revealed that utilizing vegetable oil fuels in diesel engines may require property changes in the oil or perhaps, some minor engine modifications or operating changes. This study was conducted to search for the effect of atmospheric oxygen on the puffing and bursting phe(...)

Intra-Seasonal and Annual Variation of Aerosols and Their Radiative Impact in the Sahelian Zone of Burkina Faso
Bado Nébon, Mamadou Simina Dramé, Saidou Moustapha Sall, Korgo Bruno, Demba Ndao Niang, Kieno P. Florent, Bathiebo Dieudonné Joseph
This paper deals with the characterization of aerosols in the Sahelian zone, particularly in Burkina Faso based on MODIS observations and in situ measurements of the AERONET network on the Ouagadougou site (12.2˚N, 1.4˚W). Thus, a seasonal spatial distribution of aerosols made over the period from 2001 to 2016 gives a very great variability of(...)
