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(...)

Calcul de la composition chimique dans un plasma issu de mélanges de PTFE, d’air, de cuivre et de vapeur d’eau dans le cadre d’appareillages de coupure électrique à air
Pascal André (1), Marie-Agnès Courty(2), Abdoul K. Kagoné(3), Zacharie Koalaga(3), Niessan Kohio(3), François Zougmoré (3)
Le climat des zones sub-sahariennes est marqué par une forte variabilité du taux d’humidité dans l’air, surtout entre la saison sèche et la période de mousson, et par un
empoussièrement atmosphérique élevé lors des tempêtes de poussières et de vents de sable. Sous ces conditions, les appareillages de coupure de type disjoncteur à air en conta(...)

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(...)

Classical solutions for discrete potential boundary value problems with generalized Leray-Lions type operator and variable exponent
B.A. Kyelem, S. Ouaro, M. Zoungrana
In this article, we prove the existence of solutions for some discrete nonlinear difference equations subjected to a potential boundary type condition. We use a variational technique that relies on Szulkin’s critical point theory, which ensures the existence of solutions by ground state and mountain pass methods
