Adaptations neuromusculaires des muscles extenseurs du genou : contractions fatigantes uni- vs bi-latérales
2010
The aim of this work was to determine i) the influence of the level of absolute force on the duration of the endurance time, and subsequent neuromuscular alterations in same individual at the end of an exercise performed at the same relative intensity, with one or two legs, ii) the influence of central drive on the force capacity production of the knee extensor muscles during unilateral (UL) vs. bilateral (BL) contractions, iii) activation mechanisms evolution for a serie of submaximal evoked contractions by electrostimulation (EMS). The results of the first study confirm that the endurance limit depends on the level of absolute force for the same individual, contraction duration for UL is …

Characterization of membrane structure modifications induced during plant defense signaling
2017
SPEIPMUBINRADOCT; Plasma membrane was long considered as a simple separation between internal and external cellular environment. But more, it is a dynamic interface, an exchange platform. Now, recent researches highlight its role in plant defense responses to biotic and abiotic stresses. We use the tobaccocryptogein model to study the early steps of plant cell responses to pathogen detection. The signaling cascade includes an oxidative burst triggering an increase of plasma membrane order. The level of membrane order informs us about both packing and arrangement of membrane components, this parameter being evaluated by spectrofluorimetric approaches using a lipidic environment-sensitive pro…
Zinc isotopes in Late Pleistocene fossil teeth from a Southeast Asian cave setting preserve paleodietary information
2020
Significance Dietary habits, especially meat consumption, represent a key aspect in the behavior and evolution of fossil hominin species. Here, we explore zinc (Zn) isotope ratios in tooth enamel of fossil mammals. We show discrimination between different trophic levels and demonstrate that Zn isotopes could prove useful in paleodietary studies of fossil hominin, or other mammalian species, to assess their consumption of animal versus plant resources. We also demonstrate the high preservation potential of pristine diet-related Zn isotope ratios, even under tropical conditions with poor collagen preservation, such as the studied depositional context in Southeast Asia. However, assessing the …
Mathematics Teaching for Economics Students, But How?
2018
International audience; The research presented in this poster addresses the poor performance of many economics students in their first mathematics course at university level. Two different universities are involved in the research, trying to answer the question of “how to structure teaching in mathematics to economics students at university level to strengthen their mathematical competences?”
Dynamique de l'identité européenne
2007
This study is a theorical investigation concerning European identity. The research context is social identity theory (SIT, Tajfel & Turner, 1986), self categorization theory (SCT, Turner, Oakes, Reicher & Wetherell, 1987) and their recent developments. We principally argue that transnational categories are more important to reinforce European entativity than geographical cognitive levels of inclusiveness generally considered.
Indoor noise exposure assessment of primary school children living in a french urban area
2012
International audience; The recent development of powerful noise mapping softwares allows to assess the exposure to environmental noise at the scale of an agglomeration. However noise levels inside dwellings are still unknown at such scales. To evaluate indoor noise levels and to investigate the factors which determine them, an eight-day noise measurement campaign was carried out in 50 childrens home. These children were randomly chosen among 8 or 9-year-old pupils attending the public primary schools of Besançon (France). Microphones were placed in the childs bedroom, outdoor in front of the bedrooms facade, and in the main room. Equivalent sound pressure levels (LAeq) were calculated d…
L'ACCESSO ALL'ABITAZIONE DI RESIDENZA: UN'ANALISI MULTILEVEL SULLE FAMIGLIE ITALIANE
2010
Objectives. Income inequalities depend on a large range of components, which influence living conditions of private households. Not all these elements are strictly monetary, and non-monetary components sometimes can be even more important than monetary ones. While international literature has devoted considerable attention to the study of distribution, relevance and inequalities concerning monetary income, the same cannot be said for its non monetary components. Despite this lack of attention in the literature, non monetary components often influence dramatically living conditions of private households. One of the most important component of non-monetary income is imputed rents from owner-o…
Public employees in South-Western Norway using an e-bike or a regular bike for commuting – A cross-sectional comparison on sociodemographic factors, …
2019
Large-scale analyses on the travel behavior of e-bikes are scarce, and current knowledge regarding who the e-bike owners are is inconsistent. Also, commuters represent a relevant user group with an unexploited potential. Therefore, the purpose of the present study was to examine (i) associations between type of bike (e-bike vs. regular bike) with place of residence (county), sociodemographic variables (age, sex, educational level, income and ethnicity) and habitual physical activity level, and (ii) if public employees possessing an e-bike cycle more often and longer distances to work. A cross-sectional survey was conducted in 2017 among 1977 (5.2% of eligible subjects) public employees in S…
