Cette étude a porté sur l’évaluation des eaux souterraines peu profondes du bassin versant du lac Nyos
et des implications pour le contrôle hydrogéochimique et l’usage par les rescapés de l’explosion du lac en
1986. Ils avaient pour objectif principal la caractérisation chimique des eaux souterraines en vue
d’identifier les processus hyd(...)

Culture et identité : La Culture identitaire africaine
TIBIRI Dieudonné, DOGON DADJI Umar Muhammad
La culture est ce qui nous reste quand on a tout perdu », ainsi s’exprimait un auteur africain. La culture est le fondement de toute chose, c’est pour cette raison qu’elle est un pan de notre identité. C’est pour cela que gravite autour d’elle des notions comme l’identité. De nos jours l’une rime avec l’autre au point où nous parlons désormais(...)

Arts et expressions culturelles dans les clips vidéos de Annou et Dibayagui de l’artiste Bil Aka Kora
GANOU Souleymane
Dans l’Afrique traditionnelle musique et danse, avec leurs formes diverses de théâtralisation, accompagnaient la quasi-totalité des cérémonies (mariage, baptême, lutte, culture, décès, funérailles, etc.). Des artistes africains vont s’inspirer de ces expressions artistiques traditionnelles de l’Afrique d’antan, dans l’optique de donner une tei(...)

Littérature anglophone en perspective : hommage à Cyprian Ekwensi
Umaru Muhammad DOGON DAJI et Dieudonné TIBIRI
Les francophones connaissent la littérature nigériane à travers sa figure nobélisée Wole Soyinka et son auteur de renom Chinua Achebe inscrit dans les programmes scolaires. A leur côté, Cyprian Ekwensi, pour aussi populaire qu'il apparaît au Nigeria en tant qu'écrivain dont le discours est emblématique de la di.versité nationale, est un nom mo(...)

Diversité et structure des cordons ripicoles le long de la sirba (Nord-Est du Burkina Faso).
Elice KABORE *, Oumarou SAMBARE, Amadé OUEDRAOGO et Adjima THIOMBIANO
Les Cordons ripicoles sont des végétations bordant les rivières à écoulement temporaire et qui
possèdent des sols riches et une grande capacité en bois. Ces ressources sont anarchiquement utilisées par
l’homme créant ainsi la fragmentation des berges. Cette étude s’inscrit dans le cadre d’une évaluation de la
diversité et de la structure de(...)

Entropy solutions to nonlinear elliptic anisotropic problem with variable exponent
M.B. Benboubker, H. Hjiaj, S. Ouaro
The authors establish the existence of an entropy solution for a nonlinear elliptic problem involving a Leray-Lions operator and nonlinear lower terms. The approach relies on anisotropic Sobolev spaces with variable exponent.

Studies in the Evaluation of Unconventional Oils from Burkina Faso Rich in Linoleic Acid, Oleic Acid or Other Unusual Fatty Acids
Patrice Bazongo , Imael Henri Nestor Bassole , Soren Nielsen , Mamoudou Hama Dicko and Vijai KS Shukla
A study on unconventional seed oils from Burkina Faso was carried out to determine their potential usefulness. The highest oil content was obtained with Marantes polyandra (55.0%) and the lowest with Detarium microcarpum seed oil (12.0%). Linoleic and oleic acids were the most dominant fatty acids of Balanites aegyptiaca, Combretum aculeatum,(...)

The obstacle problem associated with nonlinear elliptic equations in generalized Sobolev spaces
E. Azroul, M.B. Benboubker, S. Ouaro
This paper is devoted to the study of the following obstacle problem
−div(a(x,u,∇u))+g(x,u,∇u)=f in Ω,(1)
where Ω is an open bounded domain of ℝN(N≥2),a:Ω×ℝ×ℝN→ℝN is a Carathéodory function satisfying some growth, monotonicity and coerciveness conditions.
Under some suitable conditions on the function g and if f∈L1Ω, the authors prove the e(...)

Ageing of clay and clay–tannin geomaterials for building
I. Keita a, B. Sorgho b, C. Dembele a, M. Plea a, L. Zerbo b, B. Guel b, R. Ouedraogo b, M. Gomina c, P. Blanchart d,
Clay geomaterials for building are clay sand mixture with controlled microstructural characteristics. The macroscopic strength mostly results from the binding property of clays and can be increased with the addition of various additives as tannins from plants. Such an improvement is due to the formation of chemical complexes tannin–clay–iron h(...)

Milk and milk products provide a wealth of nutrition benefits, and are widely consumed worldwide. But raw milks can harbor dangerous microorganisms such as Salmonella or Escherichia coli, that can pose serious health risks to human. In order to assess the prevalence and antibiotics susceptibilities of Salmonella spp. and E. coli isolated from(...)

Pseudo Almost Automorphic Solutions of class r for Some Neutral Partial Functional Differential Equations
Khalil Ezzinbi, Hamidou Toure, Issa Zabsonre
The aim of this work is to investigate the existence and uniqueness of pseudo almost automorphic solutions for some neutral partial functional differential equations in a Banach space when the delay is distributed. Here we assume that the underlayed part is not necessarily densely defined and satisfies the well-known Hille–Yosida condition, th(...)
