Mapping spatial patterns of denitrifiers at large scale
2010
Little information is available regarding the landscape-scale distribution of microbial communities and its environmental determinants. Here we combined molecular approaches and geostatistical modeling to explore spatial patterns of the denitrifying community at large scales. The distribution of denitrifrying community was investigated over 107 sites in Burgundy, a 31 500 km2 region of France, using a 16 X 16 km sampling grid. At each sampling site, the abundances of denitrifiers and 42 soil physico-chemical properties were measured. The relative contributions of land use, spatial distance, climatic conditions, time and soil physico-chemical properties to the denitrifier spatial distributio…
Loss in microbial diversity affects nitrogen cycling in soil
2013
National audience; Microbial communities have a central role in ecosystem processes by driving the Earth’s biogeochemical cycles. However, the importance of microbial diversity for ecosystem functioning is still debated. Here, we experimentally manipulated the soil microbial community using a dilution approach to analyze the functional consequences of diversity loss. A trait-centered approach was embraced using the denitrifiers as model guild due to their role in nitrogen cycling, a major ecosystem service. How various diversity metrics related to richness, eveness and phylogenetic diversity of the soil denitrifier community were affected by the removal experiment was assessed by 454 sequen…
Traking nitrate reducers and denitrifiers in the environment
2005
The ability to respire nitrate when oxygen is limited has been described in taxonomically diverse microorganisms including members of the alpha-, beta-, gamma- and epsilon-proteobacteria, high and low GC Gram-positive bacteria and even Archaea. Respiratory nitrate reduction is the first step of the denitrification pathway, which is important since it is the main biological process responsible for the return of fixed nitrogen to the atmosphere, thus completing the nitrogen cycle. During the last decade, considerable knowledge has been accumulated on the biochemistry and genetics of the nitrate reductases. In this paper, we summarize the recent progress in molecular approaches for studying th…

Déni du travail et tyrannie des normes
2012
Based on the example of two quality processes deployed at the SNCF in the field of the service encounter, the aim of this article is to explore, from a clinical point of view, organizational mechanisms which encourage the denial of work. The norms of services previously defined contributed to the front office agents' denial of work, essentially because the respect of these norms became an ultimate finality. This situation has induced an "annoyed activity" (CLOT, 2009) among the front office agents, owing to the fact that the norms have been perceived as a hindrance to the accomplishment of a high-grade work. In the two previous practical examples, the reality (of work), the real work (in op…
La estatua marmórea del duque de Lerma en el castillo de Dénia, obra de Giuseppe Carlone
2018
On the 28th of August of 1612, Juan Vivas de Canamas, the ambassador of king Philip III in Genoa, commissioned the Genoese sculptor Giuseppe Carlone to carve a large statue made of Polveracio white marble representing, according to the drawing attached to the contract, the figure of a knight. The portrait depicts none other than the Duke of Lerma, whose marble effigy was intended to preside in his castle and palace of the Valencian city of Denia and was installed there at the end of 1613. In this sense, the work is historically framed in the process of renovation of the castle that Lerma began at the end of the 16th century and that included the incorporation of this exclusive artistic comm…
Artistic and religious Patronage of the Duke of Lerma in the Kingdom of València
2020
espanolEl presente estudio tiene como objetivo analizar e interpretar las labores de mecenazgo artistico y patronazgo religioso del duque de Lerma en el Reino de Valencia. Por una parte, se reflexiona sobre como sus relaciones con la ciudad de Valencia pudieron influir en sus intereses artisticos y sobre la manera en que “lo valencianoˮ estaba presente en sus colecciones personales. En este sentido, se estudian sus vinculos con los virreyes que le precedieron y sucedieron en el virreinato valenciano -como fueron el marques de Aitona, el conde de Benavente, el patriarca Ribera o el marques de Caracena- y la forma en la que favorecio la religiosidad popular valenciana de su tiempo. Por otra, …
Vers une modélisation rhétorique de la mauvaise foi?
2022
This paper offers a view of bad faith based on the study of several figures of speech: apodioxis, argument from authority, prolepsis, ratiocination, aposiopesis, comparison, etc. We try and establish formal criteria to distinguish bad faith, at the same time acknowledging that it also resorts to elements of textual continuity, cultural references and values and implications that are not necessarily manifest. Alongside well established figures of speech, we also describe more elaborate types of arguments such as narrative conglobation, lexical arsenal, identity argument, or psychological strategies like denial.
