Kinetics of Thermoascus aurantiacus solid-state fermentation on sugar-beet pulp-polysaccharide alteration and production of related enzymatic activit…
1996
International audience; The fungal solubilization of cell wall components of sugar-beet pulp, during solid-state fermentation of Thermoascus aurantiacus, is reported here. The extracellular fungal enzyme activities related to the substrate degradation were also studied. In 120 h, more than 60% of the main sugar-beet pulp polysaccharides, i.e. pectins, arabinose- and glucose-containing polysaccharides, were rapidly brought into solution by the fungus. The slow accumulation of monosaccharides compared to the fast degradation of the polysaccharides suggested that most of the released sugars were consumed by the fungus. The analysis of the enzymes present in the water extracts of the solid-stat…

Mammary pheromone-induced odour learning influences sucking behaviour and milk intake in the newborn rabbit
2016
Newborn rabbits, Oryctolagus cuniculus, locate their mother's nipples through typical orocephalic movements elicited by odour stimuli, in particular by the mammary pheromone (MP). The MP also promotes neonatal odour learning: after single pairing with the MP, an initially neutral odorant becomes able to elicit sucking-related head-searching/oral-grasping movements. However, the behavioural significance of the MP-induced odour learning remains poorly understood. We carried out three experiments to explore its influence on milk intake and compare its consequences with those resulting from nursing-induced conditioning. First, pups conditioned to an odorant by pairing with the MP on postnatal d…
Well-being and tourist experiences : a state of the art review of positive psychology studies
2017
Currently, well-being concerns individuals but also businesses and even countries. This article thus provides a synthesis of psychological researches on well-being and of those bringing closer well-being and tourism, this activity maintaining obvious links with well-being. The aim is to better understand their relationships and to offer, in particular to tourist operators, marketing recommendations suggested by the reviewed studies.
Les collections protohistoriques au musée de Lons-le-Saunier, Centre de Conservation et d’étude René Rémond
2020
Since its creation in 1817, the Lons-le-Saunier museum has been intended to house all the archaeological objects unearthed in the Jura department. Even if some collections are not included, the reserves contain most of the finds from the Jura. Protohistory plays an important role, with emblematic sites such as the Planches cave or the Chavéria necropolis. However, these collections have different legal statuses: collections listed in the museum's inventory (old collections and recent acquisitions) and collections kept in the museum but whose entry has not been regularised. With the aim of building a new museum, a vast project must be carried out in order to make the necessary acquisitions a…
Exposer l’âge du Bronze
2021
Exhibitions about the Bronze Age in France are quire a recent affair and only eighteen temporary exhibitions, most with their own catalogue, have been curated since 1986. This conference has given us the opportunity to overviev, the exhibitions that have given eirher a regional perspective of the Bronze Age or have focused on a particular theme. ln the last few years, several exhibitions have highlighred non-funerary metal deposits. The museography and public ourreach have varied for each exhibition, but ail have dealt with the difficult question of recontextualisation and how we understand and interpret archaeological data. This is particularly relevant, as the public still knows lirrle o…
Biofonctionnements des sols tropicaux et mode de gestion des terres
2000
L'effet de deux peuplements de nématodes phytoparasites a été étudié en conditions contrôlées sur la croissance du mil (#Pennisetum glaucum$). Les plants de mil (cv. IKMV 8201) ont été cultivés en pots sur du col collecté au Sud du Sénégal dans un champ cultivé (sol cultivé) et dans une jachère de 17 ans (sol de jachère). La moitié du sol de chacun des prélèvements à été stérilisée. Pour compenser l'effet de la stérilisation, six cycles de cultures de mil de deux mois ont été faits avant l'expérimentation. A l'issu de cette période, trois espèces ont été observées sur le sol cultivé non stérilisé : #Scutellonema cavanessi$, #Tylenchorhynchus gladiolatus$ et #Ditylenchus myceliophagus$, dans…
CD36 is involved in lycopene and lutein uptake by adipocytes and adipose tissue cultures
2011
International audience; Scope: Carotenoids are mainly stored in adipose tissue. However, nothing is known regarding the uptake of carotenoids by adipocytes. Thus, our study explored the mechanism by which lycopene and lutein, two major human plasma carotenoids, are transported. Methods and results: CD36 was a putative candidate for this uptake, 3T3-L1 cells were treated with sulfosuccinimidyl oleate, a CD36-specific inhibitor. sulfosuccinimidyl oleate-treated cells showed a significant decrease in both lycopene and lutein uptake as compared to control cells. Their uptake was also decreased by partial inhibition of CD36 expression using siRNA, whereas the overexpression of CD36 in Cos-1 cell…

We propose hereafter that the signature of the Space-Time metric (+++-) is not anymore frozen at the Planck scale and presents quantum fluctuations (+++±) untill 0 scale where it becomes Euclidean (++++). (i) At the albraic level we suggest an oscillation path (3,1) (4,0) exluding (2,2). We built the quotient topological space describing the superposition of the Lorentzian and the Riemanian metrics. In terms of quantum groups we evidence a relation between q-deformation and deformation of the signature. We have obtained a new algebraic construction ( a new cocycle bicross products by twisting) which allowed us to unify the Lorentzian and the Euclidean signatures within a unique quantum grou…
