The multiplicative anomaly for determinants revisited; locality
Marie Françoise Ouedraogo, Sylvie Paycha
Observing that the logarithm of a product of two elliptic operators differs from the sum of the logarithms by a finite sum of operator brackets, we infer that regularised traces of this difference are local as finite sums of noncommutative residues. From an explicit local formula for such regularised traces, we derive an explicit local formula(...)

Formulation of oral pharmaceutical dosage forms containing crude extracts of Artemisia Annua
H. Zimé-Diawara, F. Gbaguidi, J. Gbenou, A. Laleye, R. Semde, I. Some, B. Sinsin, M. Moudachirou, J. Quetin-Leclercq, B. Evrard.
Artemisia annua is an asiatic plant with curative properties against malaria,
containing artemisinin. This active compound, and its derivatives are the last few
antimalarial drugs that remain effective against multidrug resistant strains of
Plasmodium falciparum. But they are very expensive and not accessible to poor
African countries.

Polyphenolic composition of Lantana camara and Lippia chevalieri, and their Antioxidant and Antimicrobial Activities
Bangou Mindiédiba Jean, Norma Almaráz-Abarca, N. Méda, Boukaré Zeba, Martin Kiendrébeogo, J. Millogo‐Rasolodimby, O.G. Nacoulma
In the present study, the antioxidant and antibacterial activities of methanolic extracts of two Verbenaceae ( Lantana camara L. and Lippia chevalieri Moldenke: aerial part) were investigated. Their polyphenolic composition in the ethyl acetate and aqueous fractions were characterized by HPLC-DAD. The antioxidant capability of the methanolic e(...)

PAPR Distribution Analysis at the Output of Nonlinear PAPR Reducers
Désiré GUEL, Jacques PALICOT
Nonlinear PAPR reducers, such as clipping and companding techniques, are some simple methods used to reduce the Peak-to-Average Power Ratio (PAPR). In this paper, assuming that the baseband OFDM signal is characterized as a band-limited complex Gaussian process, we investigate the PAPR distribution of an OFDM signal when it is passed through a(...)

L’imagerie satellitale et la prospection minière à Dossi : une alternative à la réduction des effets induits sur l’environnement
DIPAMA Jean-Marie
La pratique classique de la recherche minière par les tranchées, les puits, les carottages et les sondages, participe à la dégradation de l’environnement. En outre, l´exploration basée sur la prospection au marteau ne permet pas toujours de mettre en évidence l´existence de concentrations économiquement rentables en dépit de l´existence de bel(...)

Analyse des stratégies des pratiques agricoles face aux changements climatiques dans la Kompienga (Burkina Faso) et le Mekrou (Bénin)
DIPAMA Jean-Marie, VISSIN Expédit Wilfrid, HEDIBLE Sidonie, BOKO Michel
Le Burkina Faso et le Bénin présentent une situation socio-économique assez similaire : une population à majorité rurale qui s’adonne essentiellement aux activités agro-pastorales. Depuis quelques décennies, cette population est en forte croissance ce qui induit une exploitation effrénée des ressources dans un contexte de crises environnementa(...)

Thermal Degradation of Polyethylene Bags and Millet Stalks: Influence of the Temperature and the Local Concentration of Oxygen on the Conversion Rate of Carbon.
Salifou K. Ouiminga, Thomas Rogaume, Tizane Daho, Franck Richard, Jean Koulidiati.
This paper concerns the influence of temperature and local concentration of oxygen on the conversion efficiency of carbon into CO, CO2, CH4, C3H8, C2H4, C2H2, C2H6, C6H6, during the thermal degradation of plastic bags and millet stalks. The experimental device used is the tubular kiln, coupled to an analyzer Fourier Transform Infrared (FTIR) a(...)

An engineered Plasmodium falciparum C-terminal 19-kilodalton merozoite surface protein 1 vaccine candidate induces high levels of interferon-gamma production associated with cellular immune responses to specific peptide sequences in Gambian adults naturally exposed to malaria
C Bisseye, L M Yindom, J Simporé, W D Morgan, A A Holder, J Ismaili
The 19-kDa C-terminal region of merozoite surface protein 1 (MSP1(19)), a major blood stage malaria vaccine candidate, is the target of cellular and humoral immune responses in humans naturally infected with Plasmodium falciparum. We have previously described engineered variants of this protein, designed to be better vaccine candidates, but th(...)
