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(...)

Biofuel from Balanites aegyptiaca: Optimization of the Feedstock Supply Chain
Linda Dominique Fabiola Bambara, Marie Sawadogo, Daniel Roy, Didier Anciaux, Joël Blin and Salifou Koucka Ouiminga
In arid and semi-arid climates, Balanites aegyptiaca (B. aegyptiaca) is a potential plant to produce oilseed-based biofuels. In this paper an optimization model for a wild biomass supply chain is presented. The model was developed to identify the optimal organization of the supply network that minimizes the cost of supplying the feedstock. It(...)

Performance Investigation of a Silicon Photovoltaic Module under the Influence of a Magnetic Field
Dioari Ulrich Combari, Emmanuel Wendsongré Ramde, Idrissa Sourabie, Martial Zoungrana, Issa Zerbo, and Dieudonné Joseph Bathiebo
Aside from the terrestrial magnetic field that is generated from the earth core, power transmission, and distribution lines, transformers and other equipment do produce a certain amount of magnetic field that could interfere with the performance of photovoltaic modules. This study conducted an experiment and investigated the performance of a s(...)

Optimization of the air gap thickness for the insulation of double-walled walls of a building
Emmanuel Ouédraogo, Ousmane Coulibaly, Boureima Kaboré, Kossi B. Imbga and Abdoulaye Ouédraogo ;
This paper presents a study on the determination of wall surface transmission coefficients, the properties of the air gap used in building insulation and temperature profiles in walls. The property values show that the air gap is a good insulator if its thickness does not exceed 4 cm. When the faces of the walls are(...)

Performance Analysis of a Boost Converter with Components Losses
Prince Abdoul Aziz Honadia, Fabé Idrissa Barro, Moustapha Sané
A theoretical study of a conventional boost converter is presented. Based on the real behavior of the components, two models of the boost converter are introduced: one dealing only with losses through inductor and capacitor and another taking into account switching losses in addition to resistive ones. From these two models, the detailed analy(...)

Bado Nébon, Mamadou Simina Dramé, Korgo Bruno, Kieno P. Florent, Saidou Moustapha Sall and Bathiebo Dieudonné Joseph
This paper analyzes aerosols in the Sahelian zone, particularly in Burkina Faso, based on in situ measurements of the AERONET network made from 1999 to 2006. Indeed, we characterize aerosols by studying their optical and microphysical parameters measured on the site of Ouagadougou (12.2° N, 1.4° W). Thus, several types of days were defined bas(...)
