Assessment of different sands potentiality to formulate an effective thermal energy storage material (TESM)
Bagré Boubou , Muritala Ibrahim Kolawole, Boukar Makinta, Daho Tizane, Nebié Jacques,Rabani Adamou, Béré Antoine
This paper presents a review of solid particles size effect on thermocline storage performance for Concentrating Solar Power (CSP) storage systems. After an overview on the different process to store thermal energy we found that a particle size of 2cm diameter is better to achieve a good sensible heat storage performance within a system call d(...)

Anti-quorum sensing and anti-biofilm activities of Securidaca longepedunculata Fresen, an endangered species from Burkina Faso
ssa Karama, Vincent Ouedraogo, Ablassé Rouamba, Moussa Compaoré and Martin Kiendrebeogo
The emergence of bacterial resistance to antibiotics is a serious challenge to the global health system. The QS inhibition is one of the approaches to fight against antibiotic resistance in bacteria. Securidaca longepedunculata is a medicinal plant that roots are the only organ used against microbial diseases. This species is threatened with e(...)

Water Resources in the Sahel and Adaptation of Agriculture to Climate Change: Burkina Faso
Babacar Lèye, Cheick Oumar Zouré, Roland Yonaba and Harouna Karambiri
In West Africa, a shift in climate conditions since the 1970s is evidenced by a decrease in average annual rainfall and an increase in temperatures between 1931–1960 and 1968–1990. The latter period was followed by a rainfall recovery since the late 1990s in the western Sahel. The prolonged rainfall deficits of the twentieth century have, howe(...)

Occurrence, behaviour and environmental risk assessment of trace metals in stream sediments from southwestern Burkina Faso, West Africa.
Aboubakar Sako, Mamadou Nimi, Sâga Sawadogo, Abdoul-Azize Kafohé Héma
In this study, the influence of source area weathering and provenance on the stream sediment geochemistry as well as the environmental impacts of selected potentially toxic trace elements (PTE) were evaluated. Four components derived from the R-mode factor analysis of additive logratio-transformed data pointed to the combined influence of weat(...)

DIFFERENTIAL AND COMPARATIVE SCREENING OF COWPEA VARIETIES TO Striga gesnerioides (WILLD.) VATKE FOR RACE SPECIFIC IDENTIFICATION IN BURKINA FASO
P. SAWADOGO, T.J. OUEDRAOGO, Z. DIENI, T.B.J. BATIENO1, N. SAWADOGO, S.L. PODA, H. ZONGO, K. GNANKAMBARY, J.B.S. TIGNEGRE, M. SAWADOGO
Significant efforts have been made to develop cowpea (Vigna unguiculata (L.) Walp.) varieties resistant to Striga gesnerioides in Burkina Faso. Despite these efforts, the resistant genotypes developed still express differential responses to Striga gesnerioides in different zones of the country. This suggests existence of intraspecific var(...)

Sterilization methods of liposomes: Drawbacks of conventional methods and perspectives
Kouka Luc Delma, Anna Lechanteur, Brigitte Evrard, Rasmané Semdé, Géraldine Piel
Liposomes are targeted drug delivery systems that are of great pharmaceutical and therapeutic interest.
Parenteral route is the main way used for liposome administration. In this case, their sterility is a requirement.
However, due to the particular sensitivity of liposomes and their tendency to physicochemical alterations, their
sterilizat(...)

Profil histologique et évolution des tumeurs intra rachidiennes opérées
Sylvain Denléwendé Zabsonre, Augustin Tozoula Bambara, Souleymane Ouattara, Adama Traore, Adeline Julie Kyelem Kafando, Alfred Aselme Dabilgou, Stéphane Klamadji, Yacouba Haro, Ibrahim Dao, Boureima Kinda, Abel Kabre
Les tumeurs intrarachidiennes sont peu fréquentes. Leur diagnostic positif est basé sur l´imagerie médicale surtout l´IRM. L´anatomopathologie apporte la certitude du diagnostic. La chirurgie est le traitement de choix pour la plupart d´entre elles. Le pronostic est fonction de la nature histologique et de l´état clinique initial du patient. N(...)
