Correlative and comparative characterization of main ion concentrations in laterite groundwater in semi-arid northern Burkina Faso
Julien Nikiema, Mario Schirmer, Walter Gläßer, Ronald Krieg
About 24 samples from hand-dug wells and boreholes were used to characterize concentrations of the main inorganic ions in a laterite environment under semi-arid climatic conditions in Tikaré, northern Burkina Faso. It was found that the most represented groundwater anion in groundwater was HCO3− with average levels of 49.1 mg/L in the dry seas(...)

Development of an in vitro Endotoxin Test for Monoolein–Water Liquid Crystalline Gel for Use as an Implant
Moustapha Ouédraogo, Rasmané Semdé, Touridomon Issa Some, Rasmata Ouédraogo, Viviane Henschel, Brigitte Evrard, Jacques Dubois, Karim Amighi and Innocent P Guissou
Purpose: Drugs that are administered by parenteral route must be apyrogenic. The aim of this study was to develop an in vitro endotoxin test for liquid crystalline gels for use as implants, using a monoolein–water liquid crystalline gel as a model. Methods: The gel-clot technique was used. The gel was dissolved first in isopropyl myristate, an(...)

Identification of Catechin as One of the Flavonoids from Combretum albiflorum Bark Extract That Reduces the Production of Quorum-Sensing-Controlled Virulence Factors in Pseudomonas aeruginosa PAO1
Quorum-sensing (QS) regulates the production of key virulence factors in Pseudomonas aeruginosa and other
important pathogenic bacteria. In this report, extracts of leaves and bark of Combretum albiflorum (Tul.)
Jongkind (Combretaceae) were found to quench the production of QS-dependent factors in P. aeruginosa PAO1.
Chromatographic fractio(...)

Les risques de dégradation des écosystèmes liés à la culture du coton au Burkina Faso: cas du parc national de Pô
DIPAMA Jean-Marie
Depuis 1995, la culture du coton connait une expansion considérable au Burkina Faso. Sa promotion vise à accroitre les revenus monétaires des paysans et lutter contre la pauvreté. L'engouement pour la culture du coton est à l'origine de l'envolée de la production du pays qui est passée de 147 000 à 600 000 tonnes entre 1996 et 2006. Cette dyna(...)

Les grandes épisodes de sécheresse et leurs implications écologiques au Burkina Faso de 1970 à 2000
DIPAMA Jean-Marie
Depuis les années 1970, le Burkina Faso vit au rythme des sécheresses répétées. Cela s’est traduit par des déficits pluviométriques très importants. Cette étude réalisée à partir des enregistrements des principaux paramètres météorologiques des dix stations synoptiques du pays présente les traits généraux du phénomène de sécheresse à travers(...)

Linking participatory and GIS-based land use planning methods : A case study from Burkina Faso
HESSEL Rudi, BERG Jolanda van den, KABORE Oumar, KEKEMA Arie van, VERZANDVOORT Simone, DIPAMA Jean-Marie, DIALLO Binta
Sustainable land use planning is crucial for realizing the aim of food security and for combating land degradation in the Sahel. A participatory land use planning workshop was organised in a village in the eastern region of Burkina Faso to investigate land use problems, their causes, effects and possible solutions. Participatory research tool(...)

Performance comparison of PRC based PAPR reduction schemes for WiLAN Systems
Hussain Sajjad, Guel Désiré, Louët Yves, Palicot Jacques
High Peak to Average Power Ratio (PAPR) is a main area of concern in multi-carrier communications as in Orthogonal Frequency Division Multiplexing (OFDM) modulated transmission. Several techniques have been devised to reduce the PAPR of the OFDM signal. One of these PAPR reduction techniques is based on Peak Reducing Carriers (PRC) concept whe(...)

Finding out Egyptian Gods’ secret using analytical chemistry: biomedical properties of Egyptian black makeup revealed by amperometry at single cells
I. TAPSOBA
Lead-based compounds were used during antiquity as both pigments and medicines in the formulation of makeup materials. Chemical analysis of cosmetics samples found in Egyptians tombs and the reconstitution of ancient recipes as reported by Greco-Roman authors have shown that two non-natural lead chlorides (laurionite Pb (OH) Cl and phosgenite(...)
