Equations des algèbres Lie triple qui sont des algèbres train
M. OUATTARA
In this paper, we consider equations of Lie triple algebras that are train algebras. We obtain two different types of equations depending on assuming the existence of an idempotent or a pseudo-idempotent. In general Lie triple algebras are not power-associative. However we show that their train equation with an idempotent is similar to train e(...)

Assessment of genetic diversity in Bambara groundnut (Vigna subterranea (L.) Verdcourt) landraces in Burkina Faso using microsatellite markers (SSR)
Adjima Ouoba, Serge Félicien Zida, Mahama Ouédraogo, Hervé Nandkangre, Hamed Mahamadi Ouédraogo, Romaric Kiswendsida Nanéma, Nerbéwendé Sawadogo, Elisabeth P Zida, Konaté N’golo Moussa, Congo Abdou Kader, Romain W Soalla, Mahamadou Sawadogo
Bambara groundnut is an important source of protein to the rural majority in sub-Saharan Africa. However, small
farmers grow locally adapted landraces which are generally low yielding. Adequate knowledge of variability within Bambara groundnut germplasm collections is crucial for crop improvement and has important implications for conservati(...)

Phytochemistry and Agro-Industrial Potential of Native Oilseeds fromWest Africa: African Grape (Lannea microcarpa), Marula (Sclerocarya birrea), and Butter Tree (Pentadesma butyracea)
HILOU Adama, Adjima Bougma and Mamoudou H. DICKO
Ethnobotanical investigations on local oilseed species in Burkina Faso revealed that oils
from tree oilseeds are frequently used for food, cosmetics and traditional medicine by local people.
To test the bio-preservative capacity, the effect of the oilseed extracts on the stabilization of Shea butter
was evaluated. Levels of bioactive phyto-(...)

Evidence that agricultural use of pesticides selects pyrethroid resistance within Anopheles gambiae sl populations from cotton growing areas in Burkina Faso, West...
Many studies have shown the role of agriculture in the selection and spread of resistance of Anopheles gambiae sl to insecticides. However, no study has directly demonstrated the presence of insecticides in breeding sources as a source of selection for this resistance. It is in this context that we investigated the presence of pesticide residu(...)

Incidence of invasive salmonella disease in sub-Saharan Africa: a multicentre population-based surveillance study
B. SOURA
Background Available incidence data for invasive salmonella disease in sub-Saharan Africa are scarce. Standardised, multicountry data are required to better understand the nature and burden of disease in Africa. We aimed to measure the adjusted incidence estimates of typhoid fever and invasive non-typhoidal salmonella (iNTS) disease in sub-Sah(...)

First report of Pepper yellow vein Mali virus associated with pepper yellow vein disease in Cote d’Ivoire
K. Séka, A. Ouattara, K.P. Assiri, K.D. Kra, M. Hoareau, P. Lefeuvre, H. Atta Diallo, J.M. Lett
In Mali and Burkina Faso, pepper yellow vein disease (PYVD) is associated with the Africa monopartite begomovirus Pepper yellow vein Mali virus (PepYVMLV). In January 2012 and August 2013, severe yellowing, leaf curling and deformation symptoms, resembling those of PYVD were observed on pepper (Capsicum spp.) across Côte d'Ivoire. Twenty leaf(...)

New strains of chickpea chlorotic dwarf virus discovered on diseased papaya and tomato plants in Burkina Faso
Alassane Ouattara, Fidèle Tiendrébéogo, Pierre Lefeuvre, Murielle Hoareau, Sohini Claverie, Edgar Valentin Traoré, Nicolas Barro, Oumar Traoré, Arvind Varsani, Jean-Michel Lett
This is the first description of full genome sequences of chickpea chlorotic dwarf virus (CpCDV; genus Mastrevirus; family Geminiviridae) identified in papaya and tomato plants sampled in Burkina Faso. The CpCDV full genome sequences from papaya and tomato share the highest pairwise sequence identity (84% and 93.5%) with Sudanese isolates of t(...)

Study of the organoleptic quality of three varieties of dried mangos : Amélie, Lippens and Brooks during storage by enzymatic tanning techniqueof peroxidases (POD) and the polyphenoloxydases (PPO)
Aminata Belem , François Tapsoba , Laurencia Toulsoumdé Songre-Ouattara , Cheikna Zongo , Aly Savadogo *
Thirty dried mango samples of Amélie, Brooks and Lippens varieties were collected for physico-chemical analyses to understanding the conditions of appearance of the enzymatic browning. These analyses showed that the higher contents of dry matter, assayable acidity, vitamin C and phenolic substrates were respectively 95,86 ± 0.01 mg/g; 1.56 ± 3(...)

Water flow in soil at small water contents: a simple approach to estimate the relative hydraulic conductivity in sandy soil
M. B. Kebré, F. Cherblanc, F. Ouédraogo, F. Jamin, B. Naon, F. Zougmoré & J.-C. Bénet
Unsaturated soil hydraulic properties are key properties in the fields of soil science and civil engineering. Because of their strong dependence on water content, there are considerable experimental and numerical difficulties in their determination, specifically in the dry range. This situation is encountered regularly in arid and semi-arid re(...)

Groundwater arsenic contamination in Burkina Faso, West Africa: Predicting and verifying regions at risk
Anja Bretzler, Franck Lalanne, Julien Nikiema, Joel Podgorski, Numa Pfenninger, Michael Berg, Mario Schirmer
Arsenic contamination in groundwater from crystalline basement rocks in West Africa has only been documented in isolated areas and presents a serious health threat in a region already facing multiple challenges related to water quality and scarcity. We present a comprehensive dataset of arsenic concen trations from drinking water wells in rura(...)

Visual appearance durability as function of natural and acceleratedageing of electrophoretic styrene-acrylic coatings: Influence of yellowpigment concentration
Tambi Ramdé, Luiz Gustavo Ecco, Stefano Rossi
Organic coatings are extensively used in many fields of engineering such as automotive or architectural industries for protection of the metallic structure against corrosion and to deliver visual aspects to the coated item. High quality paints either for outdoor or indoor applications require longer stability of their visual appearance alongsi(...)

Relations sociales, réseau scolaire et stratégies intégratrices des élèves déficients visuels au Burkina Faso
ROUAMBA-OUEDRAOGO Claudine Valérie
Au Burkina Faso, l’organisation et le financement de la scolarisation des élèves déficients visuels relèvent du monde associatif avec une faible implication de l’Etat. L’intégration des élèves déficients visuels se fait difficilement face aux difficultés relationnelles dans les familles d’accueil, le relâchement du suivi de l’association, le m(...)
