Folie et présence de l’origine dans la littérature romantique
2011
International audience; Emmanuel Kant, dans son « Esthétique transcendantale », affirme que le temps est à la fois subjectif et universel. Le temps n'est pas une donnée du monde objectif, mais il est néanmoins universellement nécessaire à la représentation humaine du monde. Les auteurs romantiques, en mettant en scène des fous, s'accordent sur le premier point, mais récusent le second. Les héros de Princesse Brambilla de E. T. A. Hoffmann, de La Félicité de la Folie de Nicolas Polévoï et d'Aurélia de Gérard de Nerval vivent dans un rapport au temps qui leur est propre. Cyclique et non linéaire, il conduit à superposer plusieurs temporalités, qui nient ainsi le principe de succession. Ce rap…

Grivoiserie, lapsus et jeux de mots dans l'oeuvre de jeunesse de Théodore de Bèze
2016
Theodore de Bèze is a french neo-latin author, i. e. a Renaissance author writing in latin, who composed a collection of poems entitled ‘The Juuenilia’ in his young years, thanks to which he earned the admiration of his contemporaries. Edited for the first time in 1548, this collection included Elegies and Epigrams among others poetic genres. Theodore de Bèze was a catholic at the time, but at the end of the same year he converted himself to Protestantism and moved to Lausanne where he became a Greek teacher. In order to fit this change of faith, he had to disavow his work, which included saucy and pagan poems.In the two following poems we will study an Elegy and an Epigram from the 1548 ‘J…
When your nose knows what you see : multisensory development of visual categorization : evidence from odor-driven face categorization in the human br…
2020
This thesis examines whether and how odors contribute to the development of visual categorization in the human brain using fast periodic visual stimulation coupled with scalp electroencephalography (FPVS-EEG). Specifically, we sought to characterize if a neural visual response selective to the face category is modulated by the presence of a body odor in both infants (Study 1, 2, 3) and adults (Study 4).In infants, the selectivity of the odor effect on visual categorization was addressed by testing separately three categories in three groups of 4-month-old infants presented with a control odor or their mother’s odor. We observed that a face-selective response is largely enhanced by maternal …

Differential memory persistence of odor mixture and components in newborn rabbits: competition between the whole and its parts
2014
Interacting with the mother during the daily nursing, newborn rabbits experience her body odour cues. In particular, the mammary pheromone (MP) contained in rabbit milk triggers the typical behaviour which helps to localize and seize the nipples. It also promotes the very rapid appetitive learning of simple or complex stimuli (odorants or mixtures) through associative conditioning. We previously showed that 24h after MP-induced conditioning to odorants A (ethyl isobutyrate) or B (ethyl maltol), newborn rabbits perceive the AB mixture in a weak configural way, i.e. they perceive the odour of the AB configuration in addition to the odours of the elements. Moreover, after conditioning to the m…
Influence of aroma compounds on the mechanical properties of pectin gels.
2004
A detailed study of the rheological behavior of pectin gels, in the presence of aroma compounds in food concentration is reported. In high methoxylated pectin (HMP) gels, it has not yet been shown if aroma compounds can be responsible for modifications in rheology. Two rheological techniques were used to measure the impact of aroma substances on rheological properties of HMP-based systems. Maximum strain to fracture (sigma F) was compared between flavored and unflavored gels on stress-displacement curve, which was obtained with uniaxial compression until fracture. An oscillatory rheometer was applied to determine the gelation time (Tgel). It appeared that all the aroma compounds studied inc…
A Revised Sex Assessment of the Epigravettian Human Remain ST1 from San Teodoro Cave (Messina, Sicily)
2013
Bias in skeletal sexing is well known and depends upon the completeness of the skeletal remains. The problem is very hard concerning prehistorical remains. We applied ‘Visual methods’ and ‘Probabilistic Sex Diagnosis’ (DSP) on the coxal bones on the Epigravettian skeleton (ST1) from San Teodoro (Messina, Sicily). On the basis of cranial characters and the overall robustness of the postcranial skeleton, it was suggested, since the time of the discovery, a male sex for ST1. This determination was later modified on the basis of the pelvic girdle morphology, and the skeleton was attributed the female sex for many years by large consensus. Our results indicate without ambiguity that ST1 is a mal…
Lipocalins in Arthropod Chemical Communication.
2021
Abstract Lipocalins represent one of the most successful superfamilies of proteins. Most of them are extracellular carriers for hydrophobic ligands across aqueous media, but other functions have been reported. They are present in most living organisms including bacteria. In animals they have been identified in mammals, molluscs, and arthropods; sequences have also been reported for plants. A subgroup of lipocalins, referred to as odorant-binding proteins (OBPs), mediate chemical communication in mammals by ferrying specific pheromones to the vomeronasal organ. So far, these proteins have not been reported as carriers of semiochemicals in other living organisms; instead chemical communicatio…
