Introduction :
L’histoire naturelle de l’infection par le virus de l’hépatite B (VHB) est influencée par plusieurs facteurs dont la grande variabilité génétique due à l’accumulation des mutations. La mutation pré-C G1896A est le variant qui a été le plus décrit au niveau de la région dans le monde. L’objectif de ce travail était de détermine(...)

Optimization of Thermal Comfort in Compressed Earth Block (CEB) Buildings in Burkina Faso
Alidou Maiga, Koffi Sagna, Karim Toussakoe, Vincent Zoma, Lareba Adélaïde Ouedraogo, Sié Kam
The objective of this study is to evaluate the impact of orientation on the thermal comfort of bioclimatic buildings in general, and
in particular those built with compressed earth blocks. A first experimental study confirmed that compressed earth blocks have
good thermal inertia, and made it possible to determine the number of annual hours(...)

Modelling the effects of diurnal temperature variation on malaria infection dynamics in mosquitoes.
Stopard IJ, Sanou A, Suh E, Cator LJ, Thomas MB, Guelbéogo WM, Sagnon N, Lambert B, Churcher TS.
Mosquito infection experiments that characterise how sporogony changes with temperature are increasingly being used to parameterise malaria transmission models. In these experiments, mosquitoes are exposed to a range of temperatures, with each group experiencing a single temperature. Diurnal temperature variation can, however, affect the sporo(...)

Pan‑C2(n+1): A Theoretical Prediction for 2D Carbon Allotropes
Xin-Qi Liu, Ang Ma, Ya-Nan Zhang, Zhi-Jun Yi, Roberts I. Eglitis, Issa Tapsoba, Ran Jia
In this work, the two-dimensional (2D) periodic armchair nanoribbon (pan-C2(n+1)) systems have been proposed and investigated by using the density functional theory (DFT). The pan-C2(n+1) systems can be easily obtained by in-plane rotating the carbon pairs C2 at certain positions in the monolayer graphene (G). The graphene nanoribbon patterns(...)

Long-lasting insecticidal nets and indoor residual sprays have played a major role in significantly reducing the burden of malaria. However, the management of mosquitoes resistant to current insecticides continues to be challenging. A promising new strategy is drug-based vector control where drugs are administered to vector hosts (human/animal(...)

Local perceptions of ginger ( Zingiber officinale Roscoe) crop management in Burkina Faso
Korotimi Deme, Moumouni Konate, Mahamadi Hamed Ouedraogo, Lardia Ali Bougma, Mahamadou Sawadogo
Ginger (Zingiber officinale Rosc., Zingiberaceae) is a highly profitable crop of great interest to growers and processors. However, there is an insufficiency of knowledge about the production practices implemented in the main production areas. This study described farmers' knowledge of ginger diversity, production constraints, tuber conservati(...)
