Evaluation of Multi-antibiotic Resistance Index (MAR) and Molecular Characterization of Pseudomonas aeruginosa Isolated in Pathological Products from Chad
Ahmat, Ahmat Mahamat, Djibrine Adoum Oumar, Hissein Ousman Abdoullahi, Cissé Hama, Fissou Henry Yandai, Kadidja Gamougam, Abdelsalam Tidjani, Savadogo Aly, Choua Ouchemi
Pseudomonas aeruginosa is a bacterium present in several ecological niches causing opportunistic infections in humans. In developing countries like Chad, this bacteria is responsible for various human pathologies. High-priority pathogens, such as Salmonella and Shigella, represent a particularly heavy burden in low- and middle-income countries(...)

Analysis, Quantification and Identification of Pesticides from Lettuce in Ouagadougou City (Burkina Faso)
Sarata Djinda, Yacouba Sanou, Samuel Paré
In Burkina Faso, chemical inputs are used massively in market gardening to increase the yields. The misuse of these chemicals is responsible of contamination of market garden products, leading to the rapid rotting of vegetables. The objective of this study was to determine the pesticides in chemical inputs applied on vegetables produced in Oua(...)

1,4‑Dihydroquinone and its Derivatives: Vibrational Spectroscopic (FT‑IR and Raman), Molecular Structure and Quantum Chemical Investigations
Ali Sanda Bawa1 · Seydou Ouedraogo2 · Adamou Zanguina3 · Mabinty Bayo‑Bangoura2 · Karifa Bayo2 · Ibrahim Natatou
Hydroquinones constitute a family of antioxidants, but are also known as electron donor molecules in charge transfer complexes. Raman and IR spectra of 1,4-dihydroquinone (H2Q) and its derivatives, 2,5-dichloro-1,4-dihydroquinone (H2QCl2)
and 2-methoxy-1,4-dihydroquinone (H2QOCH3) in solid form have been recorded. Theoretical calculations usi(...)

Introduction: Klebsiella pneumoniae is an encapsulated Gram-negative bacterium that is responsible for numerous infections in healthcare facilities worldwide and is frequently isolated. The World Health Organization has listed K. pneumoniaeas as a critical antibiotic resistant bacterial pathogen for which new antibiotics are urgently needed. T(...)

COPULA OF BERNSTEIN AND DEGREE OF DISCORDANCE
Vini Yves Bernadin LOYARA, Fabrice OUOBA et Rémi Guillaume BAGRE
The analytical expression for the degree of multivariate discordance in probability has a high level of mathematical elegance. This is why we were interested in the degree of discrepancy. In addition, while working on this expression, an application to the Bernstein copula appeared more accessible. We therefore modeled the expression for the B(...)

Optimal Sizing of Output Energy of PV Power Plants under Extreme Climate Conditions: Case of Sudanian Sahel
Boubacar SORO, Amadou DIALLO, Serge Dimitri Y. B. BAZYOMO, Adama OUEDRAOGO, Seyni SALACK; Dieudonné Joseph BATHIEBO, Sié KAM
The present work analyzes the energy production of three 50kWp photovoltaic (PV) power plants which are placed in three climate zones. The Sudano-Sahelian and Sudanian climates have lower average temperatures than the Sahelian environment. The Sudanian climate, next the Sudano-Sahelian zone, and finally the Sahelian region, have the best perfo(...)

Energy challenges in Burkina Faso: overcoming obstacles through innovation
ZOMA Vincent
Access to energy is a major challenge in Burkina Faso, with only 22.5% of the population benefiting from electricity, particularly in rural areas. This highlights the need to develop innovative solutions to improve energy supply. The aim of this study is to explore how technological innovation can be used as a lever to overcome these energy ob(...)

Greenhouse gas emission from prescribed fires is influenced by vegetation types in West African Savannas
Valaire Séraphin Ouehoudja Yaro, Loyapin Bondé , Pawend‑taoré Christian Bougma, Issoufou Sedgo, Reginald Tang Guuroh, Amanuel Woldeselassie Gebremichael, Tiga Neya, Anja Linstädter, Oumarou Ouédraogo
Greenhouse gas (GHG) emissions from prescribed fires are poorly investigated, resulting in a high uncertainty in GHG budgets. Using, a carbon mass balance approach and experimental prescribed fires in 80 plots, this study assessed carbon emissions and established emission factors (EFs) for carbon dioxides (CO2), carbon monoxide (CO), and meth(...)

Assurance-vie, développement financier et croissance économique en Afrique subsaharienne : une nouvelle approche
Relwendé Sawadogo, Benjamin Natama, et Daouda Drabo
La littérature sur l’impact de l’assurance-vie sur la performance économique dans les pays en développement reste peu concluante. Dans cet article, nous examinons la possibilité que les pays suivent des régimes de croissance différents, et testons l’hypothèse selon laquelle l’assurance-vie affecte différemment la croissance économique dépend d(...)

Apport de la géomatique dans la lutte contre la surcharge routière dans l’espace UEMOA
TOURE Aboubacar Sidiki ,SALEY Mahaman Bachir, ZOMA Vincent, KOUASSIYao Paulin
La surcharge routière représente un défi majeur pour la durabilité des infrastructures de transport, en particulier dans les pays membres de l'Union Économique et Monétaire Ouest-Africaine (UEMOA). Cette étude analyse l'impact de la surcharge sur les infrastructures routières à travers une méthodologie empruntée à la géomatique basée sur des d(...)

Pharmaceutical approaches for enhancing solubility and oral bioavailability of poorly soluble drugs
Isaïe Nyamba , Charles B Sombié, Moussa Yabré , Hermine Zimé-Diawara , Josias Yaméogo , Salfo Ouedraogo , Anna Lechanteur, Rasmané Semdé , Brigitte Evrard
High solubility in water and physiological fluids is an indispensable requirement for the pharmacological efficacy of an active pharmaceutical ingredient. Indeed, it is well established that pharmaceutical substances exhibiting limited solubility in water are inclined towards diminished and inconsistent absorption following oral administration(...)

Exploration of entomotherapeutic potential of bees’ products and termite nests from Burkina Faso
Mamadou Ouango, Hama Cissé, Rahim Romba, Samuel Fogné Drabo, Rasmané Semdé, Aly Savadogo, Olivier Gnankiné
In Burkina Faso, products and nests of insect are used for therapeutic purposes in traditional medicine. However, this
use by local populations is marginal and empirical. The objective of this study was to evaluate the antimicrobial activity of extracts of bees’ products and termite nests. Thus, the collected termite nests were finely ground.(...)

CONSTRUCTION OF A CLASS OF COPULAS WITH HORIZONTAL OR VERTICAL SECTION OF A HOMOGRAPHIC FUNCTION
Herman Tiemtoré, Bagre Remi Guillaume, Loyara Vini Yves Bernadin
The construction of multivariate distributions with arbitrary margins has been a problem of interest to statisticians for many years, but nowadays, by virtue of Sklar’s theorem, this problem can be reduced to the construction of a copula. However, there is no general method for constructing a copula. In order to provide a partial solution to t(...)

On exponential stability of mild solution of a stochastic integrodifferential equation in a complex Hilbert space
Wahabo BAGUIAN; Victorien KONANE; Claude YAMEOGO
In this work, we consider a system of stochastic integrodifferential
equations in a complex Hilbert space. We first establish the existence
and uniqueness of mild solutions for equation (1) under non-Lipschitz
conditions. Then we show under certain assumptions that the found
mild solution is exponentially stable on average of order n. Note(...)
