«Les rapports oralité/écriture ou l’inscription de l’oralité comme fondement de l’écriture de Kourouma »
Alain Joseph Sissao
La littérature africaine a connu une longue évolution qui
permet de dire que sa longue marche a été ponctuée par des
innovations, des permanences mais aussi des ruptures. Comme le
reconnaît à juste titre Jacques Chevrier dans un travail synthétique
dans la revue Notre Librairie sur « Quarante années de littérature
africaine : de William P(...)

Influence of engine load and fuel droplet size on performance of a CI engine fueled with cottonseed oil and its blends with diesel fuel
Tizane Daho, Gilles Vaitilingom, Salifou K. Ouiminga, Bruno Piriou, Augustin S. Zongo, Samuel Ouoba, Jean Koulidiati
In this study, favorable conditions to achieve good combustion of cottonseed oil and its blends with diesel fuel in a direct injection diesel engine have been highlighted. This has been performed by analyzing fuel droplet size distribution and determining engine specific fuel consumption and thermal efficiency, combustion parameters (ignition(...)

First report of the fruits flies, Ceratitis quinaria and Ceratitis silvestri, on yellow plum Ximenia americana in Burkina Faso, West Africa
A. BADOLO
Fruits of Ximenia americana provide oil that is used for food and cosmetics. However, oil production potentials are limited by damages caused by the fruit flies. This research focused on the identification of the harmful insects of the ripe fruits of X. americana, the measure of morphometric and demographic parameters. Damages were also determ(...)

Antibacterial and phytochemical studies of three Acanthaceae species used in Burkina Faso traditional medicine
Ouattara Nabèrè, Hilou Adama, Guenné Samson, Konaté Kiessoum, Zerbo Patrice, Meda Nâg-Tiero Roland, Compaoré Moussa, Kiendrébeogo Martin, Millogo F. Jeanne and Nacoulma O. Germaine
New and innovative antibacterial drugs research from plants is a best strategy to overcome the world problem about bacterial diseases. The aim of this study was to evaluate the in-vitro antibacterial activity and the phytochemical profile of various extracts from Hygrophila auriculata (Schumach.) Heine, Nelsonia canescens (Lam) Spreng and Peri(...)

Endemic Malagasy Dalbergia species inhibit quorum sensing in Pseudomonas aeruginosa PAO1
M. KIENDREBEOGO
Various species of the plant genus Dalbergia are traditionally used as medicine for sundry ailments and some of them have been shown recently to quench the virulence of Gram-positive and Gram-negative bacteria. Cell-to-cell communication mechanisms, quorum sensing (QS) in particular, are key regulators of virulence in many pathogenic bacteria.(...)

Endémie bilharzienne à Schistosoma mansoni à la vallée du Kou: caractérisation du système de transmission et impact socioéconomique
Noëllie W Kpoda, Herman Sorgho, Jean-Noël Poda, Jean Bosco Ouédraogo, Gustave B Kabré
Les schistosomiases sont sans doute l’une des maladies hydriques à qui profitent le plus les modifications environnementales et comportementales induites par la mobilisation des ressources en eau superficielle dans les pays sahéliens, comme le Burkina Faso. Des études ont établi l’existence des schistosomiases humaines à la vallée du Kou, l’un(...)

BER reduction for mQAM high-speed transmission in optical fiber networks using convolutional, BCH, RS and LDPC error correcting codes
S. R. Sanou, F. Zougmore, Z. Koalaga, M. Kebré
A comparative study of digital m-ary Quadrature Amplitude Modulation (mQAM) channel coding signals for optical high-speed transmission is presented in this article. The needs to transmit information at high speed are topical and relevant to the images, the sounds, and data of any kind, etc. The photonic networks are the subject of much researc(...)

A Study on the relation between antipatterns and the cost of class unit testing
Aminata Sabané, Massimiliano Di Penta, Giuliano Antoniol, Yann-Gael Gu_eh_eneuc.
Antipatterns are known as recurring, poor design choices, recent and past studies indicated that they negatively affect software systems in terms of understand ability and maintainability, also increasing change-and defect-proneness. For this reason, refactoring actions are often suggested. In this paper, we investigate a different side-effect(...)

Bioactive molecules from bacteria strains: case of bacteriocins producing bacteria isolated from foods
Essodolom TAALE, Aly SAVADOGO, Cheickna ZONGO, Andre J ILBOUDO and Alfred STRAORE
21 bacteria strains were isolated from traditional fermented food (Soumbala, Bikalga, indigenous yoghurt and fermented milk) using microbiology standard methods. Morphological and biochemistry analyses were done. Nine strains were selected as presumed belonging to lactic acid bacteria (LAB).These strains were characterized at species level by(...)

Intra-specific diversity of Serratia marcescens in Anopheles mosquito midgut defines Plasmodium transmission capacity
A. BADOLO
A critical stage in malaria transmission occurs in the Anopheles mosquito midgut, when the malaria parasite, Plasmodium, ingested with blood, first makes contact with the gut epithelial surface. To understand the response mechanisms within the midgut environment, including those influenced by resident microbiota against Plasmodium, we focus on(...)

Existence and Controllability Results for Some Impulsive Partial Functional Differential Inclusion
Issa Zabsonre, Gilbert Bayili, Khalil Ezzinbi,
In this work, we prove the existence of mild and extremal mild solutions for first-order semilinear non densely defined impulsive functional differential inclusions in separable Banach spaces with local and nonlocal conditions. Firstly, we show the existence of mild and extremal solutions. Secondly, we study the controllability of a semilinear(...)

Biotype status and resistance to neonicotinoids and carbosulfan in Bemisia tabaci (Hemiptera: Aleyrodidae) in Burkina Faso, West Africa
Bemisia tabaci Gennadius is a one of the major pests of cotton crops worldwide. In Burkina Faso, data on resistance to neonicotinoids and carbamate insecticides related to species/biotypes remain very scarce. To evaluate the resistance status of B. tabaci in Burkina Faso, four insecticides were tested using the leaf dip method on 10 field popu(...)
