Weeds control through tree-crop associations in a parkland of Burkina Faso
Josias SANOU, Hugues Roméo BAZIE, Madjelia Cangré Ebou DAO and Jules BAYALA
The effects of microclimate due to tree presence on weeds development were assessed under Baobab (Adansonia digitata) and Néré (Parkia biglobosa) in a parkland in Nobéré (Burkina Faso). In association with these trees, two crops were grown: a shade tolerant crop (Colocasia esculenta, taro) and a shade intolerant cereal (Pennisetum glaucum, Mil(...)

Preliminary studies on the occurrence of the foliar nematode Aphelenchoides besseyi christie in rice seeds in BURKINA FASO.
BOUMA Thio, Elise SANON, Leonard S. OUEDRAOGO, Philippe SANKARA and Salam KIEMDE
Rice is a strategic crop for Burkina Faso but the performance of improved varieties is limited by
both abiotic (rainfall and soils) and biotic (insects and diseases) factors. The negative impact of
the parasitic nematodes on the productivity of rice varieties was identified by many studies. The
objective of the current study was to evaluate(...)

DIRICHLET’S PROBLEM ON A CRACKED TRAPEZIUM
OUIGOU MICHEL ZONGO, SIÉ KAM, MOUSSA SOUGOTI, SOSTHÈNE TASSEMBEDO, KOUNHINIR SOMÉ, ALIOUNE OUÉDRAOGO, DIEUDONNÉ JOSEPH BATHIÉBO
This paper deals with solving Poisson’s equation with conditions on Dirichlet’s limits in an isosceles trapezium with two cracks. The large singular finite elements method used gives satisfactory results in all the domain of study. Numerical values obtained are very accurate for the constraint function and its first derivatives except at the 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-(...)

Growing sandpile problem with Dirichlet and Fourier boundary conditions
E. Nassouri, S. Ouaro, U. Traoré
In this work, we study the Prigozhin model for growing sandpile with mixed boundary conditions and an arbitrary time dependent angle of repose. On one part of the boundary the homogeneous Dirichlet boundary condition is provided, on the other one the Robin condition is used. Using the implicit Euler discretization in time, we prove the existen(...)

Options in human papillomavirus (HPV) detection for cervical cancer screening: comparison between full genotyping and a rapid qualitative HPV-DNA assay in Ghana
Dorcas Obiri-Yeboah, Yaw Adu-Sarkodie, Florencia Djigma, Kafui Akakpo, Ebenezer Aniakwa-Bonsu, Daniel Amoako-Sakyi, Jacques Simpore, Philippe Mayaud
Background
Modern cervical cancer screening increasingly relies on the use of molecular techniques detecting high-risk oncogenic human papillomavirus (hr-HPV). A major challenge for developing countries like Ghana has been the unavailability and costs of HPV DNA-based testing. This study compares the performance of careHPV, a semi-rapid and a(...)

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(...)

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(...)
