Toward a Better Representation of Women in Physics in Burkina Faso
P. Kafando, M.N.Sido-Pabyam, and I. Zerbo
Although 52% of Burkina Faso's population is women, boys receive preference in schooling. In 2006, only about 10% of the secondary school pupils were girls. At the University of Ouagadougou in 2000-2005 one quarter of the students were women, but just 5% of students in the sciences were women. This rate is dramatically lower in physics, both f(...)

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(...)

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(...)

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(...)

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(...)

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(...)

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(...)

Comportement à la corrosion des alliages d’aluminium recyclés pour la confection de marmites
Tambi Ramdé∗ , Lucien Bonou, Boubié Guel, Jean Boukari Legma
La composition chimique et la microstructure d’alliages d’aluminium recyclés pour la fabrication de marmites ont été déterminées par méthode spectrométrique d’émission par ICP et la diffraction de rayons X (DRX). Le comportement à la corrosion aqueuse de ces alliages a été étudié dans une solution de Na2SO4, 0,5 M par le suivi de l’évolution d(...)

Artificial signals addition for reducing PAPR of OFDM systems
Guel Desire and Palicot Jacques
One of the major drawbacks of OFDM modulation is the large envelope fluctuations which either result in an inefficient use of high power amplifiers (HPA) or decreased transmission system performance. Peak-to-Average Power Ratio (PAPR) is a very well known measure of the envelope fluctuations and has become the cost function used to evaluate an(...)

Exergy efficiency applied for the performance optimization of a direct injection compression ignition (CI), engine using biofuels.
Yao Azoumah, Joel Blin, Tizane Daho.
The need to decrease the consumption of materials and energy and to promote the use of renewable
resources, such as biofuels, stress the importance of evaluating the performance of engines based on the
second law of thermodynamics. This paper suggests the use of exergy analysis (as an environmental
assessment tool to account wastes and dete(...)
