Evaluation of the Specific Growth Rate to Predict the Biogas Production Process in a Mini-Biodigester
Noufou Bagaya, Windé Nongué Daniel Koumbem, Younoussa Moussa Baldé, Sette Diop, Bruno Korgo, Sié Kam
The paper proposes an online estimation of biogas production for a household
digester. The specific growth rate of aggregated biomass of a standard chemostat is estimated
from the online measurements of dilution rate and biogas flow rate. That estimation is based
upon usual 1-stage model without additional assumption on the online availa(...)

Determining the potential field within a square transformer
Ouigou M. Zongo, Sié Kam, Tassembedo Sosthène, Kounhinir Some, Kalifa Palm, Alioune Ouedraogo
This paper deals with determining a field of stationary potential in a transformer with square plane section, with a side measuring 4 and divided at the center by a square which side measures 2. The problem consists in solving a Laplace equation with conditions on Dirichlet’s boundaries that we solve using the method of large singular finite e(...)

Evaluation of PV Module Reliability Across A Temperature Range, Spanning A Period of 0 and 35 Years
Abdoulaye Kabré, Dominique Bonkoungou and Zacharie Koalaga
Solar energy, being both abundant and environmentally friendly, holds great promise as a renewable energy source. It can be converted into electricity through photovoltaic (PV) modules, which are crucial in the shift towards renewable energy. While PV modules are typically designed for a 25-year lifespan, their performance is significantly aff(...)

Conception, Realization and Testing of a Novel Solar Collector.
Kanré Bamogo, Thierry Sikoudouin Maurice Ky, Lareba Adélaïde Ouédraogo, Salifou Ouédraogo, Sié Kam and Dieudonné Joseph Bathiébo
The system proposed in this article is a collector made up of hemispherical concentrators. The prototype consists of four reflecting bowls covered with 8 mm glass in which 42 liters of sunflower oil circulates. The oil being the absorber itself is heated by the hot spots resulting from the concentration of the spherical reflectors. So the prop(...)

Improvement of the Sanitation of Public Places in Rural Areas in Burkina Faso: The Case of the Rural Commune of Béré in the Province of Zoundweogo
Ouindpouiré Auguste Aristide Soré, Oswald Augias Eros Kambiret, Yamine Binta Traoré, Clément Haro, Samuel Ouoba, Lionnel Sanou, Jean Bosco Bazié, Antoine Béré
This study assesses sanitation in public places in the rural commune of Béré, Burkina Faso, and proposes improvements. The diagnosis reveals a glaring lack of infrastructure: the majority of markets (88%), mosques (61%), churches (53%), and many schools (22%) lack latrines, and those that exist are often in poor condition, dirty, and poorly ma(...)

Resistivity of crystalline silicon photovoltaic cell to the electromagnetic field effects
Adama OUEDRAOGO, Rodrigue Noaga SAWADOGO, Boureima DIANDA, Mahamadi SAVADOGO, Boubacar SORO, Thierry Sikoudouin MauriceKY, Dieudonné Joseph BATHIEBO, Sié KAM
This present paper studies a crystalline silicon PV cell's resistance to electromagnetic field (EMF) effects. This study identifies an optimal doping range for silicon PV cells, enhancing their resistance to EMF damage. After solving key equations, we analyzed the cell's electrical parameters and energy processes. The current slightly drops as(...)

Impact of typical days on the optical and microphysical parameters of aerosols in urban zone of Burkina Faso, West Africa
Nébon Bado, Eric Korsaga, Boureima Dianda, Mamadou Simina Dramé, Bruno Korgo and Florent Pèlèga Kieno
Our work is based on in situ solar photometer measurements, the aim of which is to show the impact of typical days on the optical, microphysical and radiative properties of aerosols at the Ouagadougou site. To this end, a classification according to the atmospheric aerosol load defined by the aerosol optical depth (AOD) and the Angstrom coeffi(...)

Optimization of Thermal Comfort in Compressed Earth Block (CEB) Buildings in Burkina Faso
Alidou Maiga, Koffi Sagna, Karim Toussakoe, Vincent Zoma, Lareba Adélaïde Ouedraogo, Sié Kam
The objective of this study is to evaluate the impact of orientation on the thermal comfort of bioclimatic buildings in general, and
in particular those built with compressed earth blocks. A first experimental study confirmed that compressed earth blocks have
good thermal inertia, and made it possible to determine the number of annual hours(...)

Investigating the effect of a base transceiver station (BTS) on the power production of a PV module
Patrice Wendlassida Compaore, Guy Serge Tchouadep, Adama Ouedraogo, Dioari Ulrich Combari, Issa Zerbo, Martial Zoungrana
In this experimental study, a solar panel was exposed to different intensities of an Electromagnetic Field (EMF) emitted by a base transceiver station (BTS). To avoid influences from other electromagnetic (EM) waves sources the current-voltage characteristics of the PV silicon solar panel was measured, outdoor in free space on an isolated site(...)

Effect of Supplementary Irrigation Water and Organic Matter Amounts on Tomato Yield and Water Productivity in a Semi-arid Climate
YANOGO Wendzoodo Amélie Pélagie, KIMA Aimé Sévérin, OUOBA Samuel, KIMA Etienne and SANDWIDI Béné-Wendé Bernice
Although promoted as an alternative to secure rain-fed agriculture, supplementary irrigation cannot ensure sustainable food production, regardless of the rational and optimal use of organic matter. Therefore, an experiment was set up in a sandy loam soil (bulk density =1.55 g/cm3; field capacity =18%; wilting point=1.4%) to determine the optim(...)

Evaluating Supplementary Irrigation Water Depths for Improving Land and Water Productivity under Grown Tomato in a Semi-Arid Climate, Burkina Faso
Yanogo Wendzoodo Amélie Pélagie, Kima Aimé Sévérin, Ouoba Samuel, Sandwidi Béné-Wendé Bernice, Kima Etienne
Abstract:
In the actual rainwater variability and the declining water resources context, the great challenge of agriculture in Burkina Faso is to produce more with less water. That may be possible through the optimal use of water in tomato production since the yield is decreasing while the demand is still increasing particularly in the rain(...)
