5G-NR PUSCH Receiver Optimization in Context of Intra/Inter Cell Interference
Désiré Guel, Flavien Hervé Somda, P. Justin Kouraogo, Boureima Zerbo
As 5G New Radio (5G-NR) networks evolve, managing intracell and inter-cell interference, especially during uplink transmissions on the Physical Uplink Shared Channel (PUSCH) becomes increasingly challenging. This paper presents a novel approach to optimizing User Equipment (UE) and cell configuration parameters to mitigate interference and imp(...)

Medicinal value of Lippia multiflora Mondenke flowers in the fight of oral and dental infections
Ablassé Rouamba, Eric Wienybè Kamboulé, Vincent Ouedraogo, Eli Compaoré, Martin Kiendrebeogo
Oral infections pose a significant global health issue. This study assessed the antibacterial properties of methanol and dichloromethane extracts from Lippia multiflora flowers against Staphylococcus aureus ATCC 43300 and Streptococcus mutans ATCC 2517, two bacteria known to cause oral infections. The study measured the ability of these flower(...)

Phytochemical Profile and Antibacterial Activity of Solid Residues from Hydrodistillation of Cymbopogon nardus from Burkina Faso
Assétou Sankara, Jean Claude W. Ouédraogo, Mamourou Zerbo, Bassalia Ouattara and Yvonne L. Bonzi-Coulibaly
Hydrodistillation of aromatic plants is an extraction process that provides essential oils and also generates unexploited solid and liquid residues. The present study focussed on knowledge on the phytochemical profile and antibacterial potential of the solid residue resulting from the hydrodistillation of Cymbopogon nardus (CN) from Burkina Fa(...)

Modeling the Influence of Raleigh Numbers on Thermal and Fluidic Behaviors in a Trapezoid-shaped Cell
Windé Nongué Daniel Koumbem, Bouwèreou Bignan-Kagomna , Noufou Bagaya , Wend Dolean Arsène Ilboudo, Pare Daouda, Issaka Ouédraogo, Sié Kam
We model the influence of Raleigh numbers in a trapezoidal cavity. One wall among the sloping walls is exposed to a heat flux density Q=100 W/ m2 and the other inclined wall is kept adiabatic. The temperature of the two horizontal walls is assumed to be constant such that Tsup=305K is greater than Tinf=300K. The equations of heat and mass tran(...)

Sorghum Conservation Techniques in Three Agro-Climatic Zones and Their Impact on Food Security in Burkina Faso
Sibiri Nebié, Fatoumata Hama-Ba, Baloua Nebié, Roger Kaboré, Djeneba Konaté, Sibiri Bougma, Aly Savadogo
The objective of this study was to examine the sorghum preservation techniques in response to climate variability and to evaluate the prevalence of aflatoxin B1 in selected sorghum stocks in Burkina Faso. The cross-sectional study was conducted over a period of six months, from October 2020 to January 2021. A questionnaire was administered to(...)

Beyond Economics and Culture: A Demographic Perspective on Contraceptive Theory
Nathalie Sawadogo, Hervé Bassinga, Adèle M. Ngo Bayong Ngock, Zhuang Han, Sarah C. Giroux, Parfait M. Eloundou-Enyegue
Theories of contraception and fertility are currently dominated by economic and cultural arguments. A demographic perspective can usefully expand these theories through “addition,” “explication,” and “reconciliation.” The addition is about drawing attention to salient demographic forces that have previously been underconsidered whether these f(...)

Impact of Wastewater Use for Irrigation and Contamination of Lettuce by Enteric Viruses: Case of Ouagadougou Market Gardening Sites, Burkina Faso
Sibiri Sylvain Rouamba, François Tapsoba, Boukaré Kaboré, Adama Patrice Soubeiga, Moumouni Bandé, Elie Kabré & Aly Savadogo
Raw vegetables irrigated with polluted water that may contain enteric viruses can be associated with foodborne viral disease outbreaks. The objective of this study is to investigate the possible transmission of enteric viruses from irrigation water to lettuce. Therefore, we performed a commercial multiplex real-time PCR assay to monitor the oc(...)

Evaluation de l’effet des rayons gamma sur des caractères morphoagronomiques quantitatifs chez des mutants M1 de trois cultivars de gombo [Abelmoschus esculentus (L.) Moench] au Burkina Faso
Yakoro Alphonse ; Ouédraogo Mahamadi Hamed
La base génétique extrêmement étroite des variétés de gombo cultivées disponibles est la principale contrainte pour la sélection de nouvelles variétés. Ainsi, en vue de créer la variabilité par mutagenèse induite et permettre la sélection, les graines de trois cultivars de gombo, UAE22, KbG24 et KbG535, ont été irradiées aux rayons gamma du 60(...)

Enhancement of the geological mapping in weathered plutonic and metamorphic rocks areas using village water supply wells data (lithology and hydrochemistry)
Cheik Abba Cissé Ouangaré, Séta Naba, Patrick Lachassagne
In weathered plutonic and metamorphic rocks areas, because rock outcrops are rare due to the extensive regolith cover, geological mapping is largely based on the interpretation of airborne data and imagery (aerial photographs, satellite images, airborne geophysics when available, etc.). In the sub-Saharan Africa, numerous village water supply(...)
