Continuous dependence of solutions to nonlinear elliptic-parabolic-hyperbolic problem in one dimension
S. Ouaro, B. K. Bonzi
We consider a nonlinear elliptic-parabolic-hyperbolic equation of the form:
b(u)t−a(u,φ(u)x)x=f.
We show the continuous dependence of the “mild solution” of the associated Cauchy problem with respect to the data a, f and v0 without Alt and Luckhaus structure condition.

Carotenoids Content of Some Locally Consumed Fruits and Yams in Cameroon
Gouado Inocent, Aba Richard Ejoh, Touridomon Issa Some, Florian J Schweigert, Tchouanguep M.F
Vitamin A deficiency constitutes a public health problem in Cameroon. Data on provitamin A content of fruits locally consumed are scarce. To solve this nutritional problem, it is important to promote the consumption of yellow/orange fruits or green leafy vegetables which are rich sources of provitamin A. In order to achieve this, the carotenoi(...)

Changing Transition to Adulthood in Urban Burkina Faso
Calvès, Anne-Emmanuèle, Jean-François Kobiané et Edith Martel
Based on a unique retrospective survey conducted in 2000 with several cohorts of men and women in Burkina Faso, the study analyzes how the transition to adulthood in the two largest urban centers of the country has evolved over the past twenty years. Results show that both the timing and the nature of important social steps in the lives of mal(...)

Microfluidic modulus for convenient cell culture and screening experiments
I. TAPSOBA
We report on a microfluidic set-up for convenient biological experiments involving cell culture. The strategy is to use a patterned microfluidic cover plate, which can be reversibly bonded to a cell culture substrate, to achieve both long-term cell culture in parallel chambers and control of culture parameters in each chamber. The design is fu(...)

Influence of malaria on the serum levels of vitamin A, zinc and calcium of children in Douala-Cameroon
Gouado Inocent, Lehman Leopold Gustave, Some Issa T., Mbouyap Yolande, PankouiMfonkeu Joel Bertand, Ejoh Aba Richard and Tchouanguep Mbiapo Felicité
Malaria is an endemic parasitic disease that prevails particularly in warm tropical regions of the world. Micronutrient malnutrition such as vitamin A and iron deficiencies which is a public health problem in Cameroon is usually highly prevalent in malaria endemic areas. Characterizing the relationship between micronutrient status (vitamin A,(...)

E´ tude voltame´trique des sels de styryl-2 et styryl-4 pyrylium. 1re partie
Boubie´ Guel*, Dihourahouni Tountian, Yvonne Bonzy-Coulibaly, H. Traore´, Faustin Sie´ Sib
Voltammetric study of styryl-2 and styryl-4 pyrylium salts. Part 1. The redox properties of diphenyl-2,6 styryl-4 and
diphenyl-4,6 stryl-2 pyrylium salts have been studied by means of cyclic voltammetry. These salts disclose irreversible reduction and oxidation steps that are characterised by one reduction peak and two oxidation peaks, respec(...)

Traitements insecticides et dynamique des populations de Bemisia tabaci Gennadius en culture cotonnière au Burkina Faso
Résumé Considéré dans le passé comme un ravageur secondaire, Bemisia tabaci Gennadius (Homoptera: Aleyrodidae) est devenu depuis la campagne agricole 1997-1998 un des ravageurs importants en culture cotonnière au Burkina Faso. La mise en place d'une méthode de lutte efficace contre B. tabaci passe nécessairement par une meilleure connaissance(...)

Carbon and nitrogen enhancement in Cambisols and Vertisols by Acacia spp. in eastern Burkina Faso: Relation to soil respiration and microbial biomass
S. TRAORE
The current study tested the contribution of native Acacia species of the Sudano-Sahelian zone to improving organic carbon and nitrogen level in Cambisols and Vertisols with specific focus on variation in microbial biomass (C mic), soil basal respiration (C resp) and metabolic quotient (qCO 2). The results show enrichment in total organic carb(...)

Étude des interactions intramoléculaires dans les bimétallophtalocyanines par électrochimie et par spectroélectrochimie
Karifa Bayo, Mabinty Bayo-Bangoura, Mireille Mossoyan-Deneux, Doris Lexa, Guy Venance Ouédraogo.
Nous avons préparé´ et isole´ sous forme solide une série de complexes de la phtalocyanine (Pc) de zinc : ZnPc, F8ZnPc, biZnPc, F12biZnPc. Ces composés ont été´ étudiés par voltamétrie cyclique et par spectroélectrochimie. Les résultats mettent en évidence une relation de dépendance entre la structure électronique et la nature des substituants(...)

Glucose-6-phosphate dehydrogenase deficiency and sickle cell disease in Burkina Faso
Jacques Simporé, Denise Ilboudo, Karou Damintoti, Luc Sawadogo, Maria Esposito, Scott Binet, Henri Nitiema, Paul Ouedraogo, Salvatore Pignatelli, Jean-Baptiste Nikiema
Where malaria is endemic, there is an unexpected association between haemoglobinopathies and glucose-6-phosphate dehydrogenase (G-6-PD) deficiency. Their coexistence in a patient with sickle cell disease (SCD) can lead to hemolytic anemia, hemoglobinuria, sepsis, renal failure and vaso-occlusive attacks (VOA). The aim of this research was to d(...)
