La fin du Néolithique dans le sud-est de la France. Concepts techniques, culturels et chronologiques de 1954 à 2004
2006
The mediterranean France final Neolithic, between the end of Middle Neolithic Chasséen (3700-3500 Cal BC) and the end of the transitional period to the early Bronze Age, with the barbed Wire groups (1900-1800 Cal BC), is a complex period marked by the definition of almost about fifteen cultural groups and many of geographical facies and chronological phases. The chronological and technical concepts used are not less complex and varied according to researchers (Recent Neolithic or late Middle Neolithic or Final Neolithic 1, Final Neolithic and Copper Age or only Final Neolithic, and Copper Age-early Bronze Age...). If the Rhone constituted only seldom a real border during the Neolithic, it i…
The onset of the rainy season and farmers’ sowing strategy for pearl millet cultivation in Southwest Niger
2011
A multi-year (2004-2009) field survey of on-farm sowing practices in 10 villages located in south-west Niger close to Niamey, is analysed to investigate the relationships (i) between rainfall and the sowing date of pearl millet and the risk of sowing failure, (ii) between sowing and meteorological/agro-climatic onset dates, (iii) between sowing/onset dates, and simulated and observed yield/biomass at the end of the season. Even if some villages sow without any synchronous or anterior rainfall, most parcels (73% out of the 1551 available cases) are sown during and just after a 2-day wet spell receiving at least 10 mm. In fact, there is a strong correlation (r = 0.82-0.95 depending on onset d…
Sudabeh Mohafez e Yoko Tawada: due differenti processi di (ri)costruzione identitaria
2019
Yoko Tawada is a famous German-Japanese author she lives since 1982 in Germany, where she writes in Japanese and German. Sudabeh Mohafez is a German-Iranian author that she lives since 1979 in Germany and she writes only in German. This essay examines how Tawada and Mohafez approach the native country in their works. The focus of this study intends to show what different identity processes have each writers and how they are described in Akzentfrei, 2016 of Tawada and Wüstenhimmel Sternenland, 2004 of Mohafez.
Souffrir en musique
1994
Suffering to Music - Although, in its relation to suffering, music is generally reputed for possessing therapeutic virtues, several iconographie and written sources dating from the thirteenth to the fifteenth centuries attribute a harmful influence to music. This ambivalence was based on the correlation between the intensity of suffering and that of the sonorous quality of musical instruments, which in the Middle Ages were divided into two great families in accordance to the sound volume they produced. Consequently it was according to their high and strident or low and soft sonorities that the instruments were thought to act on suffering, either amplifying it or alleviating it.
Kinetics of vinyl acetate biodegradation by Pseudomonas fluorescens PCM 2123
2018
Abstract The microbial degradation of vinyl acetate (VA) by Pseudomonas fluorescens PCM 2123 strain was studied in both batch and continuous modes. The purpose of the experiments was to determine the kinetic model of the cell growth and biodegradation rate of vinyl acetate (VA), which was the sole carbon and energy source for tested microorganisms. The experiments, carried out in a batch reactor for several initial concentrations of growth substrate in the liquid phase ranging from 18.6 to 373 gsubstrate·m−3 (gs·m−3) made it possible to choose the kinetic model and to estimate its constants. The Haldane inhibitory model with the values of constants: μm = 0.1202 h−1, KS = 17.195 gs·m−3, Ki =…

Quality controls for cell cultures: identification of interspecies cross-contamination by PCR-RFLP analysis of the cytochrome b gene
2012
Cross-contaminations of a cell line with cells of different species represent a potential risk in laboratories handling human and animal cells. Therefore, it is necessary to control such contaminations. Tests based on mitochondrial DNA (mtDNA) are used in forensic analysis, phylogenetic studies and in food authentication. However, the use of mtDNA in quality controls of cell cultures is recent. Mitochondrial sequence differences of closely related animal species are five- to tenfold higher than those of nuclear genes. On the contrary, intraspecies variation in mitochondrial sequences is low in most animal species. Moreover, each cell contains 100–10.000 mitochondrial genomes. The amount of …
Isolation, purification, LC–MS/MS characterization and reactive oxygen species induced by fumonisin B1 in VERO cells
2010
Fumonisins are mycotoxins produced by Fusarium verticillioides that commonly contaminate maize and maize products. The present work shows the results of a comparative study of three different fermentation's techniques (solid and liquid medium of corn and a solid agarized medium) for the production of fumonisins B-1, B-2 and B-3 with strains of F. verticillioides. The solid medium of corn was the most effective in the production of fumonisins, being Fumonisin B-1 the one produced with higher concentration, so the extract obtained by solid fermentation process was used for FB1 purification. Fumonisins characterization and quantification were performed with reversed-phase high-performance liqu…
