Monitoring of PM2.5 Using Well-Calibrated Low-Cost Sensors over One Year in Burkina Faso
Bernard Nana, Garima Raheja, Issoufou Ouarma, Haro Kayaba, Woro Yomi Gounkaou, Tizane Daho, Antoine Béré, Abdelwahid Mellouki, Daniel M. Westervelt
Air pollution causes more than 8.34 million premature deaths worldwide. Most of these deaths occur in the Global South, particularly in Africa. However, the means of observing this air pollution in these countries are lacking. Knowledge of pollutant concentration levels and their distribution in time and space is inadequate or nonexistent in m(...)

Effect of Organic Nitrogen Supply on the Kinetics and Quality of Anaerobic Digestion of Less Nitrogenous Substrates: Case of Anaerobic Co-Digestion (AcoD) of Cassava Effluent and Chicken Droppings as a Nitrogen Source,
Haro Kayaba, Nourou Abdel Anziph Sergel Khalid, Sandwidi Sayouba , Compaore Abdoulaye, Palm Sie Auguste, Sessouma Oumou, Ouedraogo Ibrahim Kourita, Sinon Souleymane , Tubreoumya Guy Christian, Bere Antoine , Daho Tizane and Sanogo Oumar
This study aims to explore anaerobic co-digestion (AcoD) of cassava (EUM) and
poultry (FP) effluents using one inoculum/substrate ratio (30%) and three EUM vs. FP
substrate composition ratios (25:75, 50:50, and 75:25). The AcoD process was therefore
designed for 20 L batch digesters, under mesophilic conditions, with less than 5% total

Tiendrebeogo Salmwendé Eloi; Tubreoumya G. Christian; Sawadogo E. Sidwaya; Batiana Abdré; Dissa A. Oumar; Bere Antoine
Burkina Faso has plenty of sunshine for most of the year, and it is interesting to carry out solar drying in order to preserve the active ingredients of the harvested products. The drying temperature remains an essential parameter for the quality of the product to be dried. The work presented is part of an experimental study on the temperature(...)

Greenhouse Gas Emissions Assessment in Waste Management: A Case Study of Polesgo Landfill, Ouagadougou, Burkina Fas
Bernard Nana; Sid-Noma Anne-Marie Kinda; Nukunu Komlan Guillaume Attaglo; Issoufou Ouarma; Jean Koulidiati; Antoine Béré
Greenhouse gas (GHG) emissions from waste management are proving to be a major concern in terms of climate change. In terms of methane emissions at national level, studies have shown that the waste sector is second after agriculture, with 12% of emissions. The aim of this study is to quantify the GHG emissions from various waste management uni(...)

ENERGY PROBLEMATIC OF THE POWER FACTOR IN SOLAR INSTALLATIONS: CASE STUDIES, HIGHLIGHTING AND PROPOSED SOLUTIONS
Zoundi Ousmane1*, Nzihou Jean Fidele1, Tissologo Moussa1, Ouattara Frederic1, and Segda Bila Gerard2
The aim of this article is to highlight the consumption of reactive energy and the consequences of not taking it into account in solar installations. Unlike active power, it is responsible for the magnetization or induction of electrical circuits (enabling the transfer of active power) and remains constant (depending on the type of equipment)(...)

Parameters representing the thermal properties of materials are
considered to be specific to thermal inertia, and parameters modulating surface heat
transfer are considered to be related to thermal inertia. The fire behavior of
materials depends on the chemical processes involved in their thermal degradation.
For our study of the therm(...)
