A symmetrized canonical determinant on odd-class pseudodifferential operators
Marie Françoise Ouedraogo
Inspired by M. Braverman’s symmetrized determinant, we introduce a symmetrized logarithm logsym for certain elliptic
pseudodifferential operators. The symmetrized logarithm of an operator lies in the odd class whenever the operator does. Using the canonical trace extended to log-polyhomogeneous pseudodifferential operators, we define an assoc(...)

Power-associative algebras that are train algebras
M. OUATTARA
We investigate the structure of power-associative algebras that are train algebras. We first show the existence of idempotents, which are all principal and absolutely primitive. We then study the train equation involving the Peirce decomposition. When the algebra is finite-dimensional, it turns out that the dimensions of the Peirce components(...)

Anthropological features of the CFTR gene: Its variability in an African population
Bianca Maria Ciminelli, Cristina Bombieri, Cinzia Ciccacci, Francesca Belpinati, Fiorenza Pompei, Roberta Maselli, Jacques Simporé, Pier Franco Pignatti, Guido Modiano
Background: The CFTR gene (Cystic Fibrosis conductance Transmembrane Regulator) is the gene responsible for Cystic Fibrosis, the most common severe autosomal recessive disease in Europeans. It has been extensively explored in several European and European-derived populations, but poorly studied in the other major human groups.

Biodepollution of wastewater containing phenolic compounds from leather industry by plant peroxidases
Mamounata Diao • Nafisse´tou Oue´draogo • Lamine Baba-Moussa • Paul W. Savadogo • Amani G. N’Guessan • Imael H. N. Bassole´ • Mamoudou H. Dicko
This study deals with the use of peroxidases (POXs) from Allium sativum, Ipomoea batatas,
Raphanus sativus and Sorghum bicolor to catalyze the degradation of free phenolic compounds as well
as phenolic compounds contained in wastewater from leather industry. Secretory plant POXs were able to
catalyze the oxidation of gallic acid,(...)

Direct Electroanalysis of p‐Nitrophenol (PNP) in Estuarine and Surface Waters by a High Sensitive Type C/p‐NiTSPc Coating Carbon Fiber Microelectrode (CFME)
M. Pontié, L. Sikpo, G. Thouand, R. Lahan, I. Tapsoba, R. Mallet, T. Feng
We report for the first time on the elaboration of a remarkable sensitivity type C/p‐NiTSPc carbon fiber microelectrode (CFME) for p‐nitrophenol (PNP) pollutant. We observed the best performances using square wave voltammetry (SWV) technique in the place of differential pulse voltammetry (DPV). Also the combination of p‐NiTSPc optimized cycles(...)

Impact of maternal HAART on the prevention of mother-to-child transmission of HIV: results of an 18-month follow-up study in Ouagadougou, Burkina Faso
Seni Kouanda, Halima Tougri, Mireille Cisse, Jacques Simpore, Virginio Pietra, Boukare Doulougou, Gautier Ouedraogo, Charlemagne Marie Ouedraogo, Robert Soudre, Blaise Sondo Mots-clés
Mother-to-child transmission remains the main cause of global pediatric HIV infections, especially in sub-Saharan Africa. Many interventions based on single-dose antiretroviral therapy have been implemented to reduce the mother-to-child transmission of HIV. In resource-limited settings, highly active antiretroviral therapy (HAART) has only bee(...)

Comparative study of the hydrophobicity of BEA, HZSM-5 and HY zeolites determined by competitive adsorption
Arsène H. Yonli, Isabelle Gener, Samuel Mignard
A hydrophobicity study was realized for a series of siliceous and steamed BEA, HZSM-5 and HY zeolites. The hydrophobicity was assessed according to the Weitkamp method by performing water and toluene competitive adsorption experiments. The Weitkamp hydrophobicity indexes (HI) were determined for each sample. The BEA samples were the most hydro(...)

A new Experimental Method to Determine the Sorption isotherm of a Liquid in a Porous Medium
Samuel Ouoba, Fabien Cherblanc, Bruno Cousin and Jean-Claude Bénet
Sorption from the vapor phase is an important factor controlling the transport of volatile organic compounds (VOCs) in the vadose zone. Therefore, an accurate description of sorption behavior is essential to predict the ultimate fate of contaminants. Several measurement techniques are available in the case of water, however, when dealing with(...)
