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(...)

Contribution of a tyrosine-based motif to cellular trafficking of wild-type and truncated NPY Y1 receptors
Sandra Lecat, Moussa Ouédraogo, Thomas Cherrier, Fanny Noulet, Philippe Rondé, Nicole Glasser, Jean‐Luc Galzi, Yves Mély, Kenneth Takeda, Bernard Bucher
The human NPY Y1 receptor undergoes fast agonist-induced internalization via clathrin-coated pits then
recycles back to the cell membrane. In an attempt to identify the molecular determinants involved in this
process, we studied several C-terminal truncation mutants tagged with EFGP. In the absence of agonist, Y1
receptors lacking the last(...)

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(...)

La vision africaine de l'environnement chez deux écrivains burkinabè Monique ILBOUDO et André NYAMBA
SARE/MARE Honorine
Ce travail est une étude comparative sur le thème de la nature dans deux œuvres littéraires burkinabè, notamment le roman Le mal de peau de Monique Ilboudo et la nouvelle Avance mon peuple d’André Nyamba. Dans le roman, nous avons étudié comment l’expression de la nature se révèle à travers le poème introductif et dans le texte narratif ; dan(...)

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(...)

Représentations sociales de l'école et nouvelles logiques de scolarisation au Burkina Faso: l'exemple d'une zone semi rurale Zorgho
ROUAMBA OUEDRAOGO Claudine Valérie
Au Burkina Faso, la scolarité est obligatoire pour tout enfant âgé de six à huit ans du moins officiellement. L'appel à l'inscription des enfants est de mieux en mieux entendu par les parents qui se bousculent surtout à 1'approche de la rentrée pour inscrire. leurs enfants. L'école semble après quelques hésitations recueillir des suffrages du(...)

THE POETICS OF THE ROPE IN KATHERINE ANNE PORTER’S “ROPE
Michel PODA
‘‘Rope’’ by Katherine Anne Porter is a short story which hardly catches critical attention or the reader’s interest. Yet “Rope” is not less a masterpiece, in a sense. It is precisely this hypothesis that led us into investigation. Read from the angle of poetics, the narrative discloses unsuspected richness, both on the grounds of narratology a(...)

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(...)
