Modelling and experimental validation of thin layer indirect solar drying of mango slices
D. BATHIEBO
The thin layer solar drying of mango slices of 8 mm thick was simulated and experimented using a solar dryer designed and constructed in laboratory. Under meteorological conditions of harvest period of mangoes, the results showed that 3 “typical days” of drying were necessary to reach the range of preservation water contents. During these 3 da(...)

Effet du régime hydrique sur les rendements du gombo en culture de contre-saison
Rasmata NANA, Gérard ZOMBRE, Zoumbiessé TAMINI et Mahamadou SAWADOGO
L’étude à pour but de mettre en évidence la période de contre-saison favorable à la culture du gombo (Abelmoschus esculentus) et de déterminer la bonne fréquence d’arrosage. Pour cela, deux essais ont été réalisés sur trois écotypes 1 ; 19 et 22: le premier pendant la période froide (décembre-mars 2005) et le second durant la période chaude (a(...)

Existence and regularity of solutions for some partial functional integrodifferential equations 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 in Banach spaces. We suppose that the undelayed part admits a resolvent operator in the sense given by Grimmer in [R. Grimmer, Resolvent operators for integral equations in a Banach space, Transaction of American Mathemati(...)

Discovering Africa's Newest Palm.
A. OUEDRAOGO
In 1996, a paper was published discussing the identity of a palm in the genus Borassus, occurring only in West Africa. It was identified as B. flabellifer, the Asian palmyrah palm, previously unknown in Africa. This paper recounts the story of an expedition to find and document these palms, resulting in the description of Borassus akeassii, Af(...)

Drying corn grains contained in a vertical channel with constant heat flux on walls
D. BATHIEBO
A previous report [] developed a numerical model to study the influence of thermal and mass Rayleigh numbers as well as Darcy and Lewis numbers on heat and mass transfer during the drying by natural convection of coffee grains which are treated as a porous medium. The code uses the Darcy-Brinkman momentum equation and the classical natural con(...)

Ex vivo Activities of β‐Lapachone and α‐Lapachone on Macrophages: A Quantitative Pharmacological Analysis Based on Amperometric Monitoring of Oxidative Bur...
I. TAPSOBA
Artificial synapses for femtomolar detection: Amperometry at platinized carbon fibre electrodes has been used to unravel the complexity of β‐lapachone's effects on cellular oxidative stress. α‐Lapachone, the pharmacologically inactive para‐quinone isomer, did not display such characteristics, but over longer incubation periods both quinones in(...)

Sunlight inactivation of Escherichia coli in waste stabilization microcosms in a sahelian region (Ouagadougou, Burkina Faso)
MAIGA Ynoussa , DENYIGBA Kokou, WETHE Joseph, OUATTARA Aboubakar Sidiki
Experiments on sunlight inactivation of Escherichia coli were conducted from November 2006 to June
2007 in eight outdoors microcosms with different depths filled with maturation pond wastewater in
order to determine pond depth influence on sunlight inactivation of E. coli. The long-term aim was to
maximize sunlight inactivation of waterborn(...)

The present study aims at identifying the infectious agents responsible for child Acute GastroEnteritis (AGE) in Ouagadougou. From May 5 2006 to June 22 2008, 648 children aged from 2 to 41 months, with at least an average of 3 loose stools per day have been enrolled for coproculture, parasitology and virology test. Among them, 34 (5.25%) were(...)

n this study, the antioxidant and antibacterial activities of acetone extract, ethyl acetate, n-butanol and n-hexane fractions of acetone extract from leaves of Combretum nioroense Aubrév. ex Keay were investigated. The total phenolics and total flavonoids contents in the fractions and acetone extract were determined by spectrophotometric meth(...)

Entropy solutions to the obstacle problem for nonlinear elliptic problems with variable exponent and L1-data.
S. Ouaro, S. Traoré
We establish for L1-data, existence, uniqueness and continuous dependence results to the obstacle problem for nonlinear elliptic equations with variable exponent, where the variable exponent is supposed only measurable. Other classical results about stability properties of the corresponding coincidence set and the Lewy-Stampacchia inequalities(...)

Optimization of the combustion of blends of domestic fuel oil and cottonseed oil in a non-modified domestic boiler.
Tizane Daho, Gilles Vaitilingom, Oumar Sanogo
This study characterizes combustion of blends of DFO (domestic fuel–oil) and refined cottonseed oil produced in Burkina Faso at different percentages in a non-modified DFO burner by determining its overall
performance (consumption and thermal capacity) and gas emissions (CO, CO2, O2, NO, NOx, SO2). The
physical and chemical characteristics o(...)

Experimental determination of some micro-structural and hydrous properties of a terra cotta and modelisation of hygrothermal transfers
D. BATHIEBO
This experimental study present some micro-structural and thermo-hydrous properties of terra cotta. A tube, built from this porous material, bathes in a tank filled with water. The internal surface of the wall carries a water film which evaporates by forced convection of hot and dry air, allowing the storage of negative kilocalories. The form(...)
