De l’effet transformatif de l’imaginaire :

2019

The polymorphic concept of the novel and the intertextuality of the literary genres characterize the work of Georges Perec, whose writing looks into different genres, codes and models and combines them in order to preserve the singularity of each of his works. Among these W ou le souvenir d’enfance, an unclassifiable novel that alternates fiction and childhood memories, has been the result of a very difficult writing process, that genetic documents can only partly clear up. We propose to reflect on the process of re-functionalization of the adventure novel W, which appeared before as a serialized text in the journal La Quinzaine littéraire and was then integrated into the great autobiograph…

Hjelmslev et la "fonction sémiotique", du modèle structural au modèle cognitif

2008

The article discusses the concept of semiotics function in Hjelmslev, finding sources of the theory of language’s stratification. The semiotic function, which is in Hjelmslev the principle underlying the dynamic layering, is identified here as both an attraction of two heterogeneous spaces and as a set of operations of sense’s establishment. At historiographic level, this article presents a new hypothesis of interpretation, that the hjelmslevian structuralism has not built a static theory of language, disinterested to the cognitive dimension, but a careful theory to operational aspects of semiosis.

Préparation de liposomes fonctionnels pour l’encapsulation de composés bioactifs ou de sondes moléculaires fluorescentes pour l’imagerie cellulaire

2016

At ICMUB Institute, SUV liposomes have been used to achieve fluorophore encapsulation (subphtalocyanine) for cellular imaging [1] and have been bioconjugated to a peptide (bombesin) to achieve site-specificity, thanks to the structural modification of cholesterol, a component of the liposome, upon introduction of a reactive function. Hence, such liposomes fonctionnalised on the outer face may react with the terminal function of the peptide. Upon purification of the liposome by FPLC a 15 % encapsulation rate was measured by UV/Vis and attempted by ICP. The (outer) diameter of the liposomes (dDLS and dMET) ranged between 20 and 60 nm depending on the type of function or substituents on the ou…

Differential effect of hypophysectomy and growth hormone treatment on hepatic glucuronosyltransferases in male rats: Evidence for an action at a pret…

1997

International audience; The influence of growth hormone (GH) on 4-nitrophenol, bilirubin, testosterone, androsterone and estrone glucuronidation activities was studied in fully activated male rat hepatic microsomes. Sham-operated and hypophysectomized animals were injected with two different dosages of GH, mimicking either the male or female GH secretion pattern. Half the animals received thyroxine and cortisol in concentrations chosen to compensate for the lack of thyroid hormones and glucocorticoids in hypophysectomized rats. GH induced a decrease in several glucuronidation activities: bilirubin glucuronidation in both sham-operated and cortisol/ thyroxine-treated hypophysectomized rats i…

Les déterminants de la qualité des conseils d'administration français

2005

International audience; Dans cet article, nous vérifions si la "qualité" des conseils d'administration dépend de la structure de propriété et de la politique financière des grandes sociétés cotées en bourse, caractérisées par une séparation de la décision (control) et du contrôle (ownership). En nous basant sur la théorie de l'agence, nous considérons que les conseils sont de meilleure qualité lorsqu'ils comprennent une fraction élevée d'administrateurs indépendants et/ou lorsque les fonctions de direction générale et de présidence du conseil sont dissociées. Pour les 85 sociétés cotées en bourse de notre échantillon, nous confirmons notamment que la qualité des conseils croît avec la fract…

Deciphering Biotic Interactions and Their Role in Soil Microbial Community Assembly and Functions

2022

Microbial communities play a key role in ecosystem functioning as well as in plant, animal, and human welfare. Their assembly relies on different processes commonly referred to as abiotic and biotic filters. Despite the widespread emphasis on abiotic filters in terrestrial ecosystems, a growing body of evidence suggests that interactions between microorganisms play a critical role in community assembly. However, the contribution of these interactions to microbial community assembly and the factors influencing them have not been clearly established. In most cases, biotic interactions between microorganisms have been investigated based on cocultures of a handful of strains, completely overloo…

Polymer-metal plasmonic waveguide : passive and active components for integrated photonics

2009

Dielectric loaded surface plasmon polariton waveguides (DLSPPWs) enable transmission at a sub-wavelength scale of both electrical and plasmonic (optical waves at the interface between a metal and a dielectric) signals in the same circuitry. Moreover, the use of a polymer as the dielectric load enables the functionalization of DLSPPWs. Therefore, this configuration is of great interest for integrated photonic applications. However, DLSPPWs suffer strong losses due to dissipation into the metal film. We address here the possibility of compensating the losses using a configuration analogous to an optical amplifier. We first set theoretical (effective index model), numerical (differential metho…

Estimate the mean electricity consumption curve by survey and take auxiliary information into account

2012

In this thesis, we are interested in estimating the mean electricity consumption curve. Since the study variable is functional and storage capacities are limited or transmission cost are high survey sampling techniques are interesting alternatives to signal compression techniques. We extend, in this functional framework, estimation methods that take into account available auxiliary information and that can improve the accuracy of the Horvitz-Thompson estimator of the mean trajectory. The first approach uses the auxiliary information at the estimation stage, the mean curve is estimated using model-assisted estimators with functional linear regression models. The second method involves the au…
