Hydromechanical Behavior of Low-Swelling Soils Compacted at Low Water Content: Laboratory Study
Gandema, S., Kebré, M.B. & Naon, B.
Fine unsaturated soils are used in many applications, particularly in road infrastructure and in construction. These materials undergo deformations according to the stresses to which they are subjected. The purpose of this paper is to study the influence of hydromechanical stresses on the behavior of low swelling soils compacted at low water c(...)

Nutritional and Microbiological Quality of Peanut Cakes (koura-koura) Sold in the Markets and Streets of Ouagadougou and Kaya (Burkina Faso)
Sawadogo Yamkaye Aïcha, Zongo Oumarou, Cissé, Hama, Nikiéma Filbert, Kabré Elie and Savadogo Aly
Koura-koura is a crispy pancake obtained from peanuts. It is produced by hand and is widely consumed. The present work aimed to evaluate the nutritional and microbiological quality of peanut cakes called "koura-koura" sold in the markets and streets of two cities of Burkina Faso. For the koura-koura analyzes, the samples (60) were ta(...)

Experimental Measurement of Minority Carriers Effective Lifetime in Silicon Solar Cell Using Open Circuit Voltage Decay under Magnetic Field in Transient Mode
Alain Diasso, Raguilignaba Sam, Bernard Zouma, François Zougmoré
This manuscript presents a simple method for excess minority carriers’ lifetime measurement within the base region of p-n junction polycrystalline solar cell in transient mode. This work is an experimental transient 3-Dimensionnal study. The magnitude of the magnetic field B is varied from 0 mT to 0.045 mT. Indeed, the solar cell is illuminate(...)

THEORETICAL AND EXPERIMENTAL ANALYSIS OF A BOOST CONVERTER
Badiane Modou, Honadia Prince Abdoul Aziz, Barro Fabé Idrissa
A theoretical and experimental study of a conventional boost converter is presented. Based on the real behavior of the components, the conventional boost converter model dealing with both inductive and capacitive losses as well as switching losses is introduced. From this model, the detailed analytical expressions of the voltage gain factor a(...)

Formulation of clay refractory bricks: influence of the nature of chamotte and the alumina content in the clay
Moustapha Sawadogo, Mohamed Seynou, Lamine Zerbo, Brahima Sorgho, Gisèle Laure Lecomte-Nana, Philippe Blanchart, Raguilnaba Ouédraogo
Abstract: Refractory materials from kaolinitic clays and clay chamotte or quartz were studied to increase the refractoriness
under load at temperature above 1300°C. Two different clays mined in Burkina Faso were used and chamotte grains were
obtained by preliminary firing a local clay. Fired materials at 1350-1400°C present a typical granu(...)

Étude de la convection naturelle dans une cavité différentiellement chauffée
KONFE Amadou
On étudie la convection naturelle laminaire dans une cavité carrée rempli d’air dont les deux cotés
verticales sont soumises à une différence de température, tandis que les deux autres horizontaux sont
adiabatiques. Les températures de la paroi chaude et froide sont maintenues constantes. Nous avons
présenté une étude dynamique et thermique(...)

Vers une génération plus « verte » de biodiesels
Gilles Vaitilingom, Zéphirin Mouloungui, Anthony Benoist, François Broust, Tizane Daho etBruno Piriou
Dans le monde, le pétrole assure 96 % des besoins des transports, lesquels mobilisent 65 % du pétrole consommé et participent à hauteur de 20 % aux émissions de CO 2 . Afin de réduire la consommation de ressources fossiles, une des alternatives est notamment l’utilisation de « biocarburants ». Ces biocarburants sont classés en trois génération(...)
