Manufacturas sederas en la Europa ilustrada: el caso de Lyon y Valencia. Posibilidades para su estudio mediante inteligencia artificial
2021
El modelo ilustrado francés fue adaptado en la corte española como mecanismo a través del que fomentar los talleres nacionales y generar nuevas manufacturas. Ello supuso la creación de la Real Fábrica de la Seda de los Cinco Gremios de Madrid en Valencia y la creación de la Escuela de Flores y Ornatos de la Academia de Bellas Artes de San Carlos, por Real Orden del 24 de octubre de 1778, con el fin de formar a artistas en el estudio de flores y ornatos para su aplicación al textil. La aplicación de medios informáticos, que propone el proyecto SILKNOW, al estudio de estos repertorios decorativos permite una nueva mirada sobre la relación entre los modelos franceses y las traslaciones valenci…

La pintura de flores de Miguel Parra (1780-1846)
2013
Although Miguel Parra Abril (Valencia, 1780-Madrid, 1846) is one of the most important Valencian School painters of floral still lifes, this aspect of his work remains little known. The present article addresses this oversight in two ways. First, by offering an overview of his oeuvre as a painter of floral subjects from his student days at the Fine Arts Academy of Valencia through his mature works. Second, by analyzing two heretofore-unpublished floral compositions in relation to his more familiar works, particularly those located in private collections until recent years.Aunque Miguel Parra Abril (Valencia, 1780-Madrid, 1846) es uno de los pintores de flores más importantes de la Escuela v…
Chemical and biological study of saponins isolated from three malagasy species belonging to Caryophyllaceae, Pittosporaceae and Solanaceae families
2013
This thesis was carried out in the Laboratory of Pharmacognosy, in the Pharmacy section of the University of Burgundy. The principal theme of this laboratory is the research of natural compounds from tropical biodiversity, mainly saponins. In this context, the study of Malagasy plants, Polycarpaea corymbosa Lamk. (CARYOPHYLLACEAE), Pittosporum verticillatum Bojer subsp. verticillatum (PITTOSPORACEAE), Solanum incanum L. and S. heteracanthum Dunal. (SOLANACEAE) led to the isolation of fifteen natural glycosides by column chromatography, medium pressure liquid chromatography, flash chromatography, and vacuum liquid chromatography. The structures were elucidated mainly by the use of spectrosco…
Influence of organic matters on the bacterial AsIII oxidation in polluted soils
2014
International audience; The global bacterial AsIII-oxidizing activity tends to decrease As toxicity in soils and its transfer toward underlying aquifers. The influence of different types of organic matters on arsenic speciation by pure strains and soils microflora was determined. Experimental results show that the presence of organic matter has a negative effect on the specific rate of AsIII oxidation by pure strains presenting different metabolisms. In parallel, experiments are performed with various soils from different types of polluted sites: former mining and industrial sites, forest and agricultural soils impacted by mining activities. The effect of yeast extract on the AsIII-oxidizin…
Exploitation des données d’épidémio-surveillance des adventices
2013
Session 3 - Surveillance biologique du territoire : de l'observation à la décisionSPEEcolDur; L’épidémio-surveillance (ES) des espèces adventices n’a pas le même statut que celle conduite classiquement pour les maladies ou les insectes car elle ne vise que peu à piloter les besoins de lutte en cours de saison selon la météorologie. Pour autant, elle permet de rapprocher les caractéristiques du système de culture et la flore hébergée. A ce titre, les données issues de l’ES des adventices permettent de préciser la flore attendue dans un contexte local donné caractérisé par un sol un climat et un itinéraire. Comme les adventices réagissent fortement aux changements de leur environnement, l’ES …

Consequences of sown grass margin strip on weed flora
2010
The intensification of the management of weed populations, led by a potential decrease in the yield and quality of crop harvest, has largely induced their decline in arable zones across the last decades. This floristic decline in arable landscape, has induced a loss of a larger biodiversity because the presence of others organisms (birds, insects, mammals) are strongly linked with the abundance of trophic resources as weed are. To counter with this loss of biodiversity and to limit the negative impacts of farming practices on environment, numerous agri environmental schemes were launched through Europe. In France, sown grass strips were established by farmers along streams and rivers to lim…
Prévalence de pathogènes humains dans les sols français, effet des facteurs pédoclimatiques, biologiques et du mode d'utilisation des sols
2013
Soil contamination by bacterial pathogens can occur through manure, sewage sludge spreading or irrigation using waste water treatment plants effluents. Agricultural soils may act as reservoirs for these pathogens, play a significant role in their dissemination, leading to the potential contamination of food and water resources. Health risk associated with the occurrence of pathogens in environmental matrices has to be thoroughly evaluated. In this context, the objectives of this work were: i) to determine the prevalence of two pathogenic bacterial species (Listeria monocytogenes and Enterococcus faecalis) in a large collection of French soils originated from a systematic soil survey of the …
