SOLID-STATE SYNTHESIS AND PHYSICO-CHEMICAL CHARACTERIZATION OF MODIFIED SMECTITES USING NATURAL CLAYS FROM BURKINA FASO
Issaka Garikoé, Brahima Sorgho, Boubié Guel and Ingmar Persson
Solid-state intercalation was applied to prepare organo-smectites using cationic surfactants and natural clays containing smectite at various surfactant/smectite ratios. The surfactants enter the interlayers of smectites causing a swelling of the clays. The used clays were collected in Siétougou and Diabari villages located in the eastern part(...)

Silicon Solar Cell Space Charge Region and Capacitance Behavior under Electric Field
Bernard Zouma, Fabé Idrissa Barro, Prince Abdoul Aziz Honadia
This paper investigates theoretically the behavior of the space charge region of a silicon solar cell and its associated capacitance under the effect of an external electric field. The purpose of this work is to show that under illumination the solar cell’s space charge region width varies with both operating point and the external induced ele(...)

Spatial and transient modelling of land use/land cover (LULC) dynamics in a Sahelian landscape under semi-arid climate in northern Burkina Faso
Roland Yonaba, Mahamadou Koïta, Lawani Adjadi Mounirou, Tazen Fowé, Pierre Queloz, Angelbert Chabi Biaou, Dial Niang, Cheick Oumar Zouré, Harouna Karambiri, Hamma Yacouba,
Sahelian landscapes have gone through rapid changes over the past decades under high pressure from an ever-growing population, climate hazards and land degradation. Understanding drivers of change and forecasting LULC dynamics in time and space are critical for sustainable land management. This research aimed at analyzing LULC patterns and for(...)

Water Dynamics under Drip Irrigation to Proper Manage Water Use in Arid Zone
Ouédraogo, S. , Bawindsom Kébré, M. and Zougmoré, F.
The water resources reduction due to climate changes and also population increase, have contributed to increasing the constraint on water disponibility and accessibility. In the agricultural field, we need moderate soil and water resources management. This work aims to simulate water dynamics in soil under drip irrigation system in arid region(...)

Indigenous knowledge of Striga gesnerioides (Willd.) Vatke, in Burkina Faso
Pingawindé SAWADOGO, Nerbéwendé SAWADOGO, Tinga Jeremy OUEDRAOGO, Zakaria DIENI, Teyioué Benoit Joseph BATIENO, Hamadou ZONGO, Léandre PODA, Jean Baptiste De La Salle TIGNEGRE, Mahamadou SAWADOGO
Striga gesnerioides is one of the major constraints to cowpea production in West Africa. In Burkina Faso, Striga is a national phenomenon despite the control measures proposed by research. This study aims to collect farmers' perceptions of S. gesnerioides. Thus, a survey was conducted among cowpea producers in 15 localities across the four agr(...)

Les techniques scripturaires du postmodernisme à travers Murambi, le livre des ossements de Boubacar Boris Diop
TIAHO Lamoussa
Les écrivains africains, en s’ouvrant de plus en plus au reste du
monde, n’hésitent pas à emprunter certaines nouvelles techniques de
création qui semblent avoir fait leurs preuves ailleurs. C’est bien
entendu, le cas de la pratique du postmodernisme dans le processus de
création littéraire. Au-delà de la polémique inhérente à la définitio(...)

Climate change study in Burkina Faso from 1987 to 2018: An online systematic review for future directions
Silga Rimwaodo Pierre; Ouéda Adama, Ouédraogo Idrissa, Mano Komandan, Weesie, Peter D.M. & Kabré Gustave Boureima
In this paper, we perform a bibliometric analysis of published climate change research in Burkina Faso
for the period of 1987 to 2018. More specifically, this article aims at (1) revealing the temporal, and
categorical patterns in climate change research; (2) summarizing the global research trends from
multiple perspectives; and (3) prov(...)

Experimental study on performance and combustion analysis of a diesel engine fueled with Diesel and Jatropha oil blended with heptane
Yomi Woro Gounkaou, Tizane Daho, Ali Diane, Gilles Vaitilingom, Bruno Piriou, Jeremy Valette, Oumar Sanogo, Antoine Béré
This work focuses on blending Jatropha oil with diesel fuel and heptane to improve its physico-chemical characteristics for production of blends and their use as fuel in a diesel engine. The influence of the heptane content was evaluated by comparing the results obtained from the engine (performance and combustion parameters) with those of the(...)

Comparative study of the effects of Herbal and chemical Coagulants in the clarification of raw water
Anderson F. Konkobo, Mamounata Diao, Paul W. Savadogo, Jean Diarra and Mamoudou H. Dicko
The use of aluminum sulphate in clarifying raw waters raises many concerns about its impact on human health. Thus, the present study was initiated to compare the effects of Moringa oleifera and aluminum sulphate besides evaluating the association between M. oleifera or aluminum sulphate with Opuntia ficus-indica or syntofloc for water treatmen(...)

Propriétés mécanique, hydrique et thermique de briques en terre crue amendées aux coques d’arachide
Ouanmini Bobet, Mohamed Seynou, Lamine Zerbo, Halidou Bamogo, Issiaka Sanou, Moustapha Sawadogo
Des briques de terre crue élaborées à base d’une argile locale ont été amendées aux coques d’arachide pour améliorer leur performance mécanique et leur durabilité. Les coques d’arachide ont été découpées à trois longueurs respectives de 0,33 cm, 1cm et 3cm et ajoutées à la matrice argileuse à des teneurs allant de 1,8 à 3 % en masse. Les briqu(...)

The cultivation of chili peppers (Capsicum spp.) in Burkina Faso has become an important occupation and a great source of incomes, helping farmers to fight against poverty. However, local cultivars have low yields, essentially because of the pest pressure and the limited access to improved seeds. This study aims to contribute to a better knowl(...)
