Roland Yonaba, Lawani Adjadi Mounirou, Fowe Tazen, Mahamadou Koita, Angelbert Chabi Biaou, Cheick Oumar Zoure, Pierre Queloz, Harouna Karambiri and Hamma Yacouba
In this study, the Soil and Water Assessment Tool (SWAT) model is used to assess changes in surface runoff between the baseline (1995–2014) and future (2031–2050) periods in the Tougou watershed (37km²) in Burkina Faso. The study uses a combination of land use maps (for current and future periods) and a bias-corrected ensemble of 9 CMIP6 clima(...)

Production and Microbial Quality of "charmout", a Dried Meat Produced in Chad
Ali Haroun Hissein, François Tapsoba, Himeda Makhlouf, Cisse Hama, Abel Tankoano, Hassan Mahamat Ali, Cheikna Zongo, Abdessalam Tidjani, Aly Savadogo
The charmout is a meat product obtained by drying meat and used in the preparation of sauces in some Sahelian countries. However, charmout is produced and sold under unhygienic conditions. It is therefore susceptible to contamination by pathogenic and toxigenic microorganisms. The objective of this study was to isolate and identify bacterial a(...)

Epidemiology, Diagnosis and Survival of Breast Cancer: Data from the Population-Based Cancer Registry of the City of Parakou from 2017 to 2021
Luc Valère Codjo Brun, Rachidi Sidi Imorou, Nukunté David Lionel Togbenon, Marie-Claire Assomption Oloufoudi, Balle Pognon, Mawuton, Alphonse Renaud Aholou, Sèdjro Raoul Atade, Oumou Boukari, Freddy Houéhanou Rodrigue Gnangnon, Salmane Amidou, Falilath Séidou, Hierrhum Aboubacar Bambara, Kabibou Salifou, Marie Thérèse Akélé Akpo
Background: Breast cancer mortality remains high in the majority of developing countries. The Ministry of Health has established two population-based cancer registries in Benin: the first one in Cotonou in 2014 and the second one in Parakou in 2017. However, there is a scarcity of data on breast cancer survival and prognosis in Benin Republic.(...)

Background: Sub-Saharan Africa (SSA) has the highest cervical cancer (CC) burden globally-worsened by its HIV epidemics. In 2020, the World Health Organization (WHO) introduced a CC elimination strategy with goals for vaccination, screening, and treatment. To benchmark progress, we examined temporal trends in screening coverage, percent screen(...)

Caractérisation des processus orogéniques tardi-éburnéen par les mécanismes de mise en place des plutons alcalins de Wayen et de Déou
braham Seydoux TRAORE , Hermann ILBOUDO , Adama Ouédraogo YAMEOGO, Sâga SAWADOGO et Séta NABA
La structure et le contexte géodynamique de mise en place des granites alcalins ont été très peu étudiés.
Ces structures sont pourtant importantes pour interpréter les mécanismes de mise en place et déduire le
régime tectonique qui a prévalu à la fin de l’orogénèse éburnéenne (actif ou inactif). L‘objectif de ce travail
est d’utiliser la(...)

Use of supercritical CO2 for the sterilization of liposomes: Study of the influence of sterilization conditions on the chemical and physical stability of phospholipids and liposomes
Kouka Luc Delma, Noémie Penoy, Abdoul Karim Sakira, Sabrina Egrek, Rosalie Sacheli, Bruno Grignard, Marie-Pierre Hayette, Touridomon Issa Somé, Brigitte Evrard, Rasmané Semdé, Géraldine Piel
The effects of four potential supercritical carbon dioxide (ScCO2) sterilization conditions on the chemical stability
of 9 phospholipids and on the physicochemical characteristics of liposomes consisting of stable phospholipids,
as well as their sterilization efficiency were evaluated. These conditions were : C1 (ScCO2/70 ◦C/150

Optimization of a High Capacity Industrial Bar Press for Jatropha Curcas Oil Extraction
Moussa Abdoul-Aziz , Sidibe Sadio Sayon , Ouedraogo Abdoulaye , Ouedraogo Emmanuel , Ousmane Moctar , Coulibaly Ousmane
This study allowed us to achieve the optimal yield for the extraction of Jatropha Curcas oil from the main operating variables of an industrial press. We used an industrial bar press with a large extraction capacity to carry out this work. Two interesting and indicative parameters on the influence of the efficiency of the pre(...)

Knowledge, Attitudes, and Practices Related to Antibiotic Use and Antibiotic Resistance among Poultry Farmers in Urban and Peri-Urban Areas of Ouagadougou, Burkina Faso
Sawadogo Abdallah , Kagambèga Assèta , Moodley Arshnee , Ouedraogo Abdoul Aziz, Barro Nicolas and Dione Michel
Increased use of antibiotics in livestock is a public health concern, as it poses risks of antibiotic residues and antibiotic-resistant pathogens entering the food chains and infecting humans. A cross-sectional survey was conducted on 216 poultry farms to study knowledge, attitudes and practices of poultry farmers on the use of antibiotics in(...)

Le Conseil National de la Révolution (CNR) et la gestion de l’électricité au Burkina Faso (1983-1987)
DEMBEGA Salam
Depuis la nationalisation de son secteur énergétique en 1968, la Haute-Volta tente de vulgariser l’usage de l’électricité. Essentiellement produite à partir d’hydrocarbures importés et aux coûts en constante augmentation, cette énergie reste limitée à un cercle restreint de villes où sa gestion était marquée par des déficits liés au manque de(...)

Analysis of Dengue Disease Transmission Model with General Incidence Functions
Harouna OUEDRAOGO and Aboudramane GUIRO
In this work, we propose a non-linear system of differential equations that models the dynamics of transmission of dengue fever. Then, we perform a stability analysis of this model. In particular, we prove that when the threshold of the model called the basic reproduction ratio is less than unity, the disease-free equilibrium is globally asymp(...)

Introduction: Central Nervous System (CNS) malformations usually leave the family in disarray and doctors’ staff powerless. In developed countries, the rigorous application of preventive measures has contributed to a significant reduction incidence of these malformations. In African societies, mystical-religiou(...)

Preparation and characterization of foamed concrete using a foaming agent and local mineral resources from Burkina Faso.
Alassane Compaoré, Moustapha Sawadogo, Youssouf Sawadogo, Moussa Ouedraogo, Brahima Sorgho, Mohamed Seynou, Philippe Blanchart, Lamine Zerbo,
The paper describes lightweight-foamed concretes (LFC) that were formulated from cement, natural sand, and
foam from a foaming agent with densities of 600 and 700 kg/m3. The identified mineral phases in the cement are
alite, belite, Celite, ferrite, calcite, and gypsum. The obtained foamed concretes have a porosity varying from
29.17 to 37.(...)

Modelling and optimisation of ultrasound‑assisted extraction of roselle phenolic compounds using the surface response method
Abdoudramane Sanou, Kiessoun Konaté, Kaboré kabakdé, Roger Dakuyo, David Bazié, Sama Hemayoro & Mamoudou Hama Dicko
Extracts from Hibiscus sabdariffa L. (roselle) have been used traditionally as a food, in herbal medicine, in hot and cold beverages, as flavouring or coloring agent in the food industry. In vitro and in vivo studies and trials provide evidence, but roselle is poorly characterised phytochemically due to the extraction processes. The optimizati(...)
