A linear system with Fresnel reflectors as a concentrator was designed, built,and tested for solar cooking. It consists of 17 reflectors (blades) made of 1 mmthick aluminum sheet metal, mounted on a metal support to ensure theiralignment. The system has a geometric concentration of 17. The system is dif-ficult to operate because the blades mus(...)

Geospatial estimation and projection of electricity demand in Burkina Faso for efficient and sustainable rural electrification
Boubou Bagré, Giacomo Falchetta, Jacques Nébié, Bowendkuni Armand Korsaga, Abdoulaye Kaboré, Richard Zoundi, Tizane Daho and Antoine Beré,
Approximately 75% of Burkinabè, predominantly in rural areas, still lack electricity access at home. This energy poverty also impacts productive sectors like agriculture and small enterprises, as well as public facilities such as education and healthcare. To gauge the electricity requirements to tackle energy poverty and project them to the ye(...)

THERMAL PERFORMANCE OPTIMIZATIONS OF A HEMISPHERICAL SOLAR COOKER WITH ALUMINUM SHEET CONCENTRATORS: APPLICATION TO FOOD COOKING
Ladifata Mogmenga, Bouto Kossi Imbga, Thierry, Sikoudouin Maurice Ky, Salifou Ouedraogo, Sie Kam, Joseph Dieudonne Bathiebo.
Cooking is a method of transforming food by exposing it to heat. Solar cookers allow us to cook food using the heat generated from the sun's rays. In this work, we present an experimental study of a hemispherical solar cooker tested with and without glazing. In the context of sustainable development, in order to reduce environmental impact, th(...)

The AMBRE Project: Line-broadening and stellar rotation of ESO/FEROS archived spectra
F. Bado, P. de Laverny, Z. Kam, A. Recio-Blanco, P. A. Palicio and J. Koulidiati
Context. Stellar rotation is a fundamental parameter in studies of the formation and evolution of stars. However, large homogeneous catalogues of rotational velocities derived from high-resolution stellar spectra are still lacking.
Aims. The main objective of this work is to determine the line-broadening parameter (Vbroad), which is a proxy f(...)

Determination of the optimal operating distance of a solar PV module under the influence of the electromagnetic field
V. de Dieu Bokoyo Barandja, Idrissa Sourabie, Mamoudou Saria, Eric Simonguy, N. L. Privace M'bouana, Christian Kenfack-Sadem, Ramatou Saré, E. Wendsongré Ramdé, Martial Zoungrana, Issa Zerbo
The effect of an electromagnetic field (EMF) on the various electrical parameters of a photovoltaic (PV) solar cell or PV module is not uniform. A high intensity or proximity to an electromagnetic field increases the photoelectric current, while the photovoltage has the opposite effect. Thus, for certain electrical parameters, the EMF can be c(...)

Gasification of Raw, Roasted and Carbonized Cashew Shells in a Fixed-Bed Co-current Gasifier
Bénéwindé Edwige 2ème Jumelle Ouédraogo, Gado Harouna Ibrahim, Wend-Kuni Gisele Bilgo, Tizane Daho, Oumar Sanogo & Antoine Bere
The utilization of agricultural residues for power generation is an opportunity to reduce fossil fuel usage and foster a sustainable circular economy. The gasification of agricultural residues in some localities in Burkina Faso has made it possible to access electricity. However, the majority of gasifiers in operation in Burkina Faso are shut(...)
