Processus sensoriels cognitifs et comportementaux impliqués dans la perception des mélanges odorants alimentaires complexes chez le lapin nouveau-né …
2015
Within each breath, a large diversity of volatiles molecules of the surrounding reaches our olfactory receptors. Despite the chemical complexity of the natural environment, the organisms succeed to represent their world using relevant information carried by single odorants or mixtures. Focusing on the perception of these stimuli, we explored the processes involved in the treatment of this complex information, sometimes supported by mixtures or sub-mixtures. The treatment is based on two processes: the elemental mode, which allows extracting the odor quality of all or some of the elements, or the configural mode which allows the holistic representation of the mixture. In this doctoral thesis…
High-resolution laser spectroscopy of long-lived plutonium isotopes
2017
Long-lived isotopes of plutonium were studied using two complementary techniques, high-resolution resonance ionisation spectroscopy (HR-RIS) and collinear laser spectroscopy (CLS). Isotope shifts have been measured on the $5f^67s^2\ ^7F_0 \rightarrow 5f^56d^27s\ (J=1)$ and $5f^67s^2\ ^7F_1 \rightarrow 5f^67s7p\ (J=2)$ atomic transitions using the HR-RIS method and the hyperfine factors have been extracted for the odd mass nuclei $^{239,241}$Pu. Collinear laser spectroscopy was performed on the $5f^67s\ ^8F_{1/2} \rightarrow J=1/2\; (27523.61\text{cm}^{-1})$ ionic transition with the hyperfine $A$ factors measured for $^{239}$Pu. Changes in mean-squared charge radii have been extracted and s…
Limits to CO2-Neutrality of Burning Wood. (Review)
2016
Abstract Consumption of wood as a source of energy is discussed with respect to efficiency and restraints to ensure sustainability of the environment on the grounds of a simple analytical model describing dynamics of biomass accumulation in forest stands – a particular case of the well-known empirical Richards’ equation. Amounts of wood harvested under conditions of maximum productivity of forest land are presented in units normalised with respect to the maximum of the mean annual increment and used to determine the limits of CO2-neutrality. The ecological “footprint” defined by the area of growing stands necessary to absorb the excess amount of CO2 annually released from burning biomass is…
Nuove regole di applicazione del diritto UE in sede nazionale?
2022
Two important judgments of the Consiglio di Stato (Italy) allow revisiting general institutions relating to the primacy of EU law and the instruments that guarantee its application in national law. Among others are the direct effect of the directives, the need for a preliminary ruling, and the so-called double preliminary ruling. Finally, the essay highlights some critical issues regarding the limits of the non-application of the law, the overcoming of the res judicata, and the temporary suspension of the ousting effect of a rule of EU law by national courts.
Le renouvellement du contrôle juridictionnel de l’administration au moyen du recours pour excès de pouvoir
2017
The role of the administrative judge (the excess of power) has evolved due to the implementation of the various texts adopted recently as well as the developments in the case-law in recent years. In many areas, its role now goes beyond the mere confrontation of an administrative act with the rule of law. At the heart of the annulment decision is a statement and an assessment of the facts, apart from the interpretation of the law, which were usually separated by the principle of separation between the administration and its judge.Some jurisprudence which has become very classical, as well as others more recent, can be considered as characteristic manifestations of this new tendency of the ju…
Comparison of inter-trial recovery times for the determination of critical power and W' in cycling
2017
Critical Power (CP) and W’ are often determined using multi-day testing protocols. To investigate this cumbersome testing method, the purpose of this study was to compare the differences between the conventional use of a 24-h inter-trial recovery time with those of 3 h and 30 min for the determination of CP and W’. Methods: 9 moderately trained cyclists performed an incremental test to exhaustion to establish the power output associated with the maximum oxygen uptake (p V O2max), and 3 protocols requiring time-to-exhaustion trials at a constant work-rate performed at 80%, 100% and 105% of p VO2max. Design: Protocol A utilised 24-h inter-trial recovery (CP24/W’24), protocol B utilised 3-h in…
