Contribution au dimensionnement d’un prototype de four de potier à tirage d’air naturel
Salifou Koucka Ouiminga, Thomas Rogaume, Tizane Daho, Franck Richard, Jean Koulidiati
Le présent travail concerne l’étude de l’influence des paramètres géométriques d’un four de potier, sur
les rendements des émissions gazeuses polluantes, afin d’aider au dimensionnement de fours plus respectueux de
l’environnement. Au cours de ces investigations, les émissions de NO, CO2, O2 et N2 ont été suivies. Les fours
de potier consid(...)

Hemoglobins S and C interfere with actin remodeling in Plasmodium falciparum–infected erythrocytes
K. SIMPORE
The hemoglobins S and C protect carriers from severe Plasmodium falciparum malaria. Here, we found that these hemoglobinopathies affected the trafficking system that directs parasite-encoded proteins to the surface of infected erythrocytes. Cryoelectron tomography revealed that the parasite generated a host-derived actin cytoskeleton within th(...)

Impacts of land-use on West African savanna vegetation: a comparison between protected and communal area in Burkina Faso
A. THIOMBIANO
Biodiversity matters in many aspects for human well-being by providing timber and non-timber products. The most important ecosystems providing these products in West Africa are savannas. In the context of land-use changes, there is an urgent need to understand the impact of land-use on savanna vegetation and biodiversity. This study assesses t(...)

Antioxidant and anti-inflammatory effects of Scoparia dulcis L.
M. KIENDREBEOGO
Different extracts were obtained from Scoparia dulcis L.(Scrophulariaceae) by successive extraction with hexane, chloroform, and methanol. These extracts exhibited significant antioxidant capacity in various antioxidant models mediated (xantine oxidase and lipoxygenase) or not mediated (2, 2-diphenyl-picrylhydrazyl, ferric-reducing antioxidant(...)

Population structure of three woody species in four ethnic domains of the sub‐sahel of Burkina Faso
T. K. Sop, J. Oldeland, U. Schmiedel, I. Ouedraogo, A. Thiombiano
In developing countries many people depend on woody resources for their livelihoods. Monitoring human impact on the populations of socio-economically important species is therefore important for the conservation of vulnerable plants.
In order to assess and compare the population structure and regeneration patterns of three multipurpose spec(...)

The Ironical Figure of Reuben Bourne in NathanielHawthorne’s “Roger Malvin’s Burial”
PODA Michel
The figure of Reuben Bourne in “Roger Malvin’s Burial” by
Nathaniel Hawthorne is quite striking. Appearing as the fictional duplicate of
a classical knight hero, endowed with bravery, self-denial and sense of
honour, he falls short of the reader’s expectations in the course of events. He
is but a wounded hero, whose real capacity cannot ma(...)

Approche participative et gouvernance locale des ressources forestières dans la forêt classée de Tuy : atouts et contraintes
DIPAMA Jean-Marie
Partout en Afrique sahélienne, le souci de préserver la biodiversité dans certains écosystèmes avait amené les pouvoirs publics à prendre en charge la gestion des ressources naturelles dont les forêts classées. Mais, pour des raisons diverses, ces enclaves subissent d’énormes préjudices suite à une exploitation de plus en plus accrue, souvent(...)
