La coqueluche du nouveau-né en Afrique
K. NAGALO
Résumé La coqueluche est une maladie contagieuse due à Bordetella pertussis, qui peut être prévenue par la vaccination. Elle est grave chez les enfants de moins de 3 mois. Ceux-ci sont dans la plupart des cas contaminés par leurs parents alors qu'ils sont peu ou pas protégés contre la maladie. Les présentations atypiques sont fréquentes et la(...)

In Vitro Antiplasmodial and Antibacterial Activities of Canthium multiflorum Schum & Thonn (Rubiacea) Extracts
Akomo EF, Zongo C, Karou SD, Obame LC, Savadogo A, Atteke C, Traore AS
Because of the resistance of pathogens to actually available drugs, there is a continuous need for new agents to cure several diseases such as malaria and microbial infections. In the establishment of new drugs, plant are often a source of new leads, indeed aqueous, acetone and methanol extracts of Canthium multiflorum were tested for antiplas(...)

Clipping Formulated As an Adding Signal Technique for OFDM Peak Power Reduction
Guel Desire and Palicot Jacques
Due to the simplest way for PAPR reduction, clipping technique have been proposed and seem to be promising for use in commercial systems. In this paper, the conventional clipping technique is formulated as an adding signal technique for PAPR reduction. We show that, when clipping occurs very rarely, the adding signal for PAPR reduction commonl(...)

Weak solutions for anisotropic nonlinear elliptic equations with variable exponents
B. Koné, S. Ouaro, S. Traoré
We study the anisotropic boundary-value problem
−∑i=1N∂∂xiai(x,∂∂xiu)=fin Ω,u=0on ∂Ω,
where Ω is a smooth bounded domain in ℝN (N≥3). We obtain the existence and uniqueness of a weak energy solution for f∈L∞(Ω), and the existence of weak energy solution for general data f dependent on u.

Les phénomènes de nitration des eaux souterraines dans la région de Tilabéry (Niger)
Marou Gourouza , Garba Zibo , Karifa Bayo
Résumé : Des échantillons d’eaux de consommation provenant de trois cent points d’eau
souterraine repartis sur toute la région de Tillabéry (Niger) ont été analysés. Les résultats
révèlent qu’environ 2/3 de ces points d’eaux connaissent un début de pollution au nitrate ;
10% sont impropres à la consommation humaine avec des teneurs supérieu(...)

Woody vegetation structure and composition at four sites along a latitudinal gradient in western Burkina Faso.
Fidèle Bognounou, Adjima Thiombiano, Patrice Savadogo, Joseph Issaka Boussim, Per Christer Odén, Sita Guinko
Understanding the distribution patterns of plant species and the underlying factors is crucial to the conservation and management of plant communities in savannah-woodland
ecosystems. This article describes the species composition, structure and diversity of woody species at four sites along a latitudinal gradient in the North Sahelian, South(...)

Local existence and regularity of solutions for some partial functional integrodifferential equations with infinite delay in Banach Spaces
Khalil Ezzinbi, Hamidou Toure, Issa Zabsonre
In this work, we study the existence and regularity of solutions for some partial functional integrodifferential equations with infinite delay in Banach spaces. We suppose that the undelayed part admits a resolvent operator in the sense of Grimmer [R. Grimmer, Resolvent operators for integral equations in a Banach space, Transactions of the Am(...)

Living at the edge: biogeographic patterns of habitat segregation conform to speciation by niche expansion in Anopheles gambiae
Carlo Costantini , Diego Ayala , Wamdaogo M Guelbeogo , Marco Pombi , Corentin Y Some , Imael HN Bassole , Kenji Ose , Jean- Marie Fotsing , N'Falé Sagnon , Didier Fontenille , Nora J Besansky and Frédéric Simard
Background: Ongoing lineage splitting within the African malaria mosquito Anopheles gambiae is
compatible with ecological speciation, the evolution of reproductive isolation by divergent natural selection acting on two populations exploiting alternative resources. Divergence between two molecular forms (M and S) identified by fixed(...)

Weak and entropy solutions to nonlinear elliptic problems with variable exponent.
S. Ouaro, S. Traoré
The authors study nonlinear boundary value problem with the nonlinear operator of p-Laplacian-type and Dirichlet boundary condition. The authors obtain two existence results: in first a unique entropy solution is obtain and in the second a week solution is produced.
