Thoughts on 3D Digital Subplane Recognition and Minimum-Maximum of a Bilinear Congruence Sequence
E Andres, D Ouattara, G Largeteau-Skapin, R Zrour
In this paper we take first steps in addressing the 3D Digital Subplane Recognition Problem. Let us consider a digital plane (w.l.o.g. ) and a finite subplane S of P defined as the points (x, y, z) of P such that . The Digital Subplane Recognition Problem consists in determining the characteristics of the subplane S in less than linear (in the(...)

Nutritional and Anti-Nutrient Composition of Three Kola Nuts (Cola nitida, Cola acuminata and Garcinia kola) Produced in Benin
103. DAH-NOUVLESSOUNON Durand, Adolphe Adjanohoun, Haziz Sina, Pacôme A. Noumavo, Nafan Diarrasouba, Charles Parkouda, Yann E. Madodé, Mamoudou H. DICKO, Lamine Baba-Moussa
Kola nuts were regularly chewed by West Africans and Beninese in particularly. The aim of this
study was to investigate nutritional and anti-nutrient content of three Benin’s kola nuts (Cola nitida,
Cola acuminata and Garcinia kola). Proximate composition of the three species of kola nuts
was assessed using standard analytical AOAC methods.(...)

Energy-free Security in Wireless Sensor Networks
Adel Elgaber (1) , Julien Bernard (1) , Yacouba Ouattara (1)
Wireless sensor networks are often deployed in open and uncontrolled environments that make them more vulnerable to security attacks. Cryptographic algorithms can be used to protect the data collected by the sensors against an intruder. The cost in terms of energy to provide enough security can be quite large as these algorithms may be very co(...)

Modelling Study of Magnetic Field’s Effects on Solar Cell’s Transient Decay
Senghane Mbodji, Martial Zoungrana, Issa Zerbo, Biram Dieng, Gregoire Sissoko
Experimental setup of transient decay which occurs between two steady state operating points is recalled. The continuity equation is resolved using both the junction dynamic velocity (Sf) and back side recombination velocity (Sb). The transient excess minority carriers density appears as the sum of infinite terms. Influence of magnetic field o(...)

A 3D Modelling of Solar Cell’s Electric Power under Real Operating Point
Mayoro Dieye, Senghane Mbodji, Martial Zoungrana, Issa Zerbo, Biram Dieng, Gregoire Sissoko
This work, based on the junction recombination velocity (Sfu) concept, is used to study the solar cell’s electric power at any real operating point. Using Sfu and the back side recombination velocity (Sbu) in a 3D modelling study, the continuity equation is resolved. We determined the photocurrent density, the photovoltage and the solar cell’s(...)

Phenolic composition, in vitro antioxidant effects and tyrosinase inhibitory activity of three Algerian Mentha species: M. spicata (L.), M. pulegium (L.) and M. rotundifol...
M. KIENDREBEOGO
The leaves of three Mentha species harvested in Algeria, Mentha spicata L.(MS), Mentha pulegium L.(MP) and Mentha rotundifolia (L.) Huds (MR) were examined for their content in polyphenols and for some activities-linked biological properties these could impart. The contents in total phenolics (TPC) and flavonoids (TFC) were evaluated by the Fo(...)

SUITABILITY OF GROUNDWATER AND SURFACE WATER FOR DRINKING AND IRRIGATION PURPOSE IN ZIO RIVER BASIN (TOGO).
TAMPO L., GNAZOU D.T.M., KODOM T. , OUEDA A. & BAWA L.M.
Zio River basin plays a particular importance as a potential water resource for irrigation, drinking and for other various purposes relating to socioeconomic activities. These socioeconomic activities considerably change water quality and quantity in this basin. An investigation was carried out by collecting 52 groundwater samples and 168 surf(...)

Constacyclic codes over F_q + uF_q + vF_q + uvF_q
Joël Kabore, Mohammed E. Charkani
Let q be a prime power and Fq be a nite eld. In this paper, we study constacyclic
codes over the ring F_q + uF_q + vF_q + uvF_q, where u2 = u; v2 = v and uv = vu: We
characterized the generator polynomials of constacyclic codes and their duals using
some decomposition of this ring.

Effectiveness of the prevention of mother-to-child transmission of HIV protocol applied at Saint Camille Medical Centre in Ouagadougou, Burkina Faso
Serge Theophile Soubeiga, Cyrille Bisseye, Rebecca Compaore, Elsa Assengone, Djeneba Ouermi, Florencia Djigma, Tani Sagna, Virginio Pietra, Jacques Simpore
Introduction: Despite many prevention efforts, the number of children infected by HIV in sub-Saharan Africa through vertical transmission remains high. This infection can be reduced through programmes of prevention of mother-to-child HIV transmission (PMTCT). The objective of this study was to evaluate the effectiveness of the PMTCT protocol a(...)

To determine genetic diversity among 43 cultivars of Kumba group (Solanum aethiopicum L.), 17 simple sequence repeat (EST-SSR) markers were tested. Nine (9) EST-SSR markers used were polymorphic among the accessions studied. A total of 19 alleles were identified with an average of 2 alleles per marker. Furthermore, the accessions studied showe(...)

La politique religieuse de la France à l’égard des missions étrangères en AOF, 1900-1945
Magloire Somé
La France a entendu pratiquer au début du XXe siècle une politique de neutralité religieuse en AOF, suite à la loi de séparation des Églises et de l’État, édictée en 1905, mais cette notion de neutralité religieuse fut un vain mot dans la pratique.
Cet article vise à montrer les ambiguïtés de la politique coloniale de la France en matière rel(...)

Recherche sur le dépistage de la difficulté d’apprentissage scolaire au Burkina Faso et la proposition de remédiation cognitive
François SAWADOGO, Elie Corneille DAKUYO
L’enseignant est souvent le premier à constater qu’un élève est en difficulté d’apprentissage scolaire. S’il lui est reconnu d’être celui alerte sur la difficulté, il est moins établi qu’il soit aussi apte à mettre en œuvre des activités de remédiation cognitive dans la pratique de son métier pour juguler les difficultés d’apprentissage scolai(...)

How to take pedagogical requirements into account to design e-learning platforms by using patterns?
Tonguim Ferdinand Guinko, Laurence Capus Hatem Ben Sta
Pattern concept is often used to design educational systems. On the one hand, educational team uses patterns to describe pedagogical scenarios and on the other hand software engineers apply them in e-learning software development process. However, there is no any synergic framework between these two uses of patterns, that could allow pedagogic(...)
