Characterization of carbonaceous and nitrogenous species during the reductive and oxidative combustion of biomass : Case of millet stalks
Salifou Koucka Ouiminga, Thomas Rogaume, Arsène H. Yonli, Alfa Oumar Dissa, Jean Koulidiati
Millet stalks are used as fuel in pottering crafting in Africa. A study was conducted to characterize the gaseous species produced during the reductive and oxidative combustion of millet stalks. The experiment was carried out on temperature ranging from 800-1000°C, using the tubular furnace, coupled with two gas analyzers i.e. Analyzer Fourier(...)

Trace elements and their correlations in hand-dug wells in a laterite environment in a semi-arid region: Case study of Tikaré, Northern Burkina Faso
Julien Nikiema, Mario Schirmer, Walter Gläßer, Ronald Krieg
In many regions of the world and especially in arid and semi-arid areas, groundwater is the major source of drinking water for most of the rural population. The main reason is probably its accessibility through hand-dug wells. However, the resource is supplied in most of the cases to the population as raw water because groundwater is assumed t(...)

Study of droplet vaporization of various vegetable oils and blends of domestic fuel oil–cottonseed oil under different ambient temperature conditions
T. Daho, G. Vaitilingom, O. Sanogo, S. K. Ouiminga, B.G. Segda, J. Valette, P. Higelin, J. Koulidiati
In this work, the evaporation characteristics of different pure vegetable oils (cottonseed oil, jatropha oil, and rapeseed oil), domestic fuel oil (DFO) and blends of domestic fuel oil and cottonseed oil have been studied using the fibre-suspended droplet evaporation technique. The constants of evaporation of pure products were determined as w(...)

Air quality study in urban centers: case study of Ouagadougou, Burkina Faso
Bernard Nana, Oumar Sanogo, Paul W. Savadogo, Tizane Daho, Médard Bouda, and Jean Koulidiati.
In this work, a study on air quality in the city of Ouagadougou (Burkina Faso) was carried out. The concentration levels of NO2, SO2, BTEX and PM10 in the city have been quantified. The results show that NO2 concentrations (range from 22 to 27 μg m-3 on average) in the city remain below the limit set by the WHO standard, except for downtown wh(...)

CYCLIC VOLTAMMETRY AND REDUCTION MECHANISTIC STUDIES OF STYRYLPYRYLIUM PERCHLORATES
Jean Claude W. Ouédraogo1, Issa Tapsoba1, Boubié Guel2, Faustin Sié Sib1 and Yvonne Libona Bonzi-Coulibaly1*
The reduction and oxidation potentials of methylated 4-styrylpyrylium and 6-styrylpyrylium perchlorates have been evaluated using cyclic voltammetry, in comparison to their non-methylated derivatives values. The reduction peak of all studied compounds remained chemically irreversible. The presence of the electron-donating methyl group on pyryl(...)
