Preparation et etudes vibrationelle et electronique de complexes de la phtalalocyanine d’or avec des ligands axiaux phosphines et phosphites
Ali Sanda BAWA, Lassane Tarpaga, Mabinty Bayo-Bangoura, Seydou Ouédraogo, Karifa Bayo
Nous avons préparé et étudié par spectrométries optique et vibrationnelle une série de complexe de la
phtalocyanine d’or (AuPc) portant des ligands axiaux [PPh3, P(OMe)3, POH(OEt)2, P(OPh)3]. L’analyse des spectres
infrarouges dans le domaine 2000 cm-1-400 cm-1 confirme la réaction de la phtalocyanine d’or avec les différents ligands. Les co(...)

EFFECTS OF ALFALFA ON AGGREGATE STABILITY, AGGREGATE PRESERVED-C AND NUTRIENTS IN REGION MOUNTAIN AGRICULTURAL SOILS 1 YEAR AFTER ITS PLANTING
Patrizia Guidi, Livia Vittori Antisari, Boussa T. Maré, Gilmo Vianello, Gloria Falsone
In mountain areas, water erosion plays an important role on soil structure and can strongly affect its functions. Suitable management practices, namely choice of crops, may be able to improve aggregate stability and reduce soil loss by surface runoff. To study the effects of cover crops on aggregation in mountain soils, we investigated a soil(...)

Prevalence and resistance profile of extended-spectrum β-lactamases-producing Enterobacteriaceae in Ouagadougou, Burkina Faso
Dissinviel Stéphane Kpoda, Nathalie Guessennd, Juste Isidore Bonkoungou, Mohamed Baguy Ouattara, Fernique Konan, Abraham Ajayi, Jacques Simpore, Rasmata Ouedraogo, Koiné Maxime Drabo, Lassana Sangare, Mireille Dosso, Alfred Traore
Increasing bacterial resistance to antimicrobial agents has become an issue of concern. A major problem of the treatment of infections caused by Enterobacteriaceae using antibiotics is the emergence of Extended-spectrum β-lactamases (ESBL)-producing Enterobacteriaceae. This study aims to determine the prevalence of ESBL-producing Enterobacteri(...)

SEIS MODEL WITH MULTIPLE LATENT STAGES AND TREATMENT IN AN EXPONENTIALLY GROWING POPULATION
S. Ouaro, D. Ouédraogo
An SEnIS epidemiological model with vital dynamics in an exponentially growing population is dis- cussed. Without treatment three threshold parameters R0,R1 and R2 determine the dynamic of compartments sizes and that of the fractions. With the treatment the dynamics of the population and that of the epidemic depend on three other threshold par(...)

Union breakdown in West African cities: The cases of Ouagadougou and Lomé
GNOUMOU THIOMBIANO Bilampoa
Le mariage reste une institution forte en Afrique, mais les ruptures d'unions peuvent être fréquentes, en particulier dans les zones urbaines. Cependant, cette question est encore peu étudiée, notamment en Afrique de l'Ouest. L’objectif de l’étude est d’examiner les tendances et les facteurs associés au divorce dans deux villes d'Afrique de l'(...)

Effect of the fermentation on the microbial population occurring during the processing of zoom-koom, a traditional beverage in Burkina Faso
95. TAPSOBA Fidèle Wend-bénédo, Hagrétou SAWADOGO-LINGANI, Donatien KABORE, Diarra COMPAORE-SEREME and Mamoudou H. DICKO
Zoom-koom is a traditional fermented beverage from Burkina Faso based on cereals such as millet or
sorghum. Samples were collected from two local production sites of microenterprises (Zogona and
Dassasgho). Microorganisms dynamic during the production of zoom-koom were enumerated using
pour plate methods. The titratable acidity, pH and temp(...)

Characteristics of the Street Food Sector in N'Djamena, Chad
Mayoré AD, Tidjani A, Bessimbaye N, Asséta K, Kuan AT, René D, Bagré TS, et Nicolas B
Preparation and sale of street food is a sociocultural fact in Chad. Since one decade, this activity has a remarkable growth due to galloping urbanization of our cities and especially to N’Djamena city, capital of Chad. However, the organization of this activity causes great hygienic risks for these foods thus impeding their great nutritional(...)

H i kinematics and mass distribution of Messier 33
S Zacharie Kam, Claude Carignan, Laurent Chemin, Tyler Foster, Ed Elson, Tom H Jarrett
A new deep H i survey of the galaxy Messier 33 is presented, based on observations obtained at the Dominion Radio Astrophysical Observatory. We observe a perturbed outer gas distribution and kinematics in M33, and confirm the disk warping as a significant twist of the major axis of the velocity field, although no strong tilt is measured, in ag(...)

Impact of bark and foliage harvesting on fruit production of the multipurpose tree Afzelia africana in Burkina Faso (West Africa)
Blandine Marie Ivette Nacoulma . Anne Mette Lykke . Salifou Traore´ . Brice Sinsin . Adjima Thiombiano
Abstract In sub-Saharan Africa, extraction for daily livelihood needs often results in uncontrolled exploitation of bark and leaves of valuable medicinal and fodder trees. However, overharvesting of bark and foliage can reduce fruit production and threaten reproduction. This study evaluates the impact of combined bark and foliage harvesting on(...)

Analysis of Vulnerability to Drought and Flooding in the Ouémé River Basin at Bétérou in Benin (West Africa)
KOUDAMILORO Olivier, DIPAMA Jean-Marie, VISSIN Expédit W.
In Benin, the principal risks which threaten the populations are the floods and the drought. The objective of this work is to analyze the zones vulnerable to the flood and the dryness in the catchment area of Ouémé with Bétérou. To achieve this goal, of the data climatological (height of rains day laborers and monthly) of 1965 to 2012 were col(...)
