Impact of land-use type and bark-and leaf-harvesting on population structure and fruit production of the baobab tree (Adansonia digitata L.) in a semi-arid savanna,...
A. THIOMBIANO
Non-timber forest products (NTFPs) strongly contribute to livelihood security in the semi-arid tropics. There is increasing concern about the population status of NTFP-providing trees and therefore a need for their sustainable use. Thus, this study examines the impact of land-use type on the multipurpose baobab tree (Adansonia digitata L.) in(...)

Composition and Antimicrobial Activities of Lippia multiflora Moldenke, Mentha x piperita L. and Ocimum basilicum L. Essential Oils and Their Major Monoterpene Alcohols Alone and in Combination
Imaël Henri Nestor Bassolé , Aline Lamien-Meda , Balé Bayala , Souleymane Tirogo , Chlodwig Franz , Johannes Novak , Roger Charles Nebié and Mamoudou Hama Dicko
Essential oils from leaves of Lippia multiflora, Mentha x piperita and Ocimum basilicum from Burkina Faso were analysed by GC–FID and GC–MS. Major components were p-cymene, thymol, β-caryophyllene, carvacrol and carvone for L. multiflora, menthol and iso-menthone for M. x piperita and, linalool and eugenol for O. basilicum. The(...)

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(...)

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(...)

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(...)

The Poetics of the Rope in Katherine Anne Porter’s “Rope”
PODA Michel
‘‘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
narratolo(...)
