Tear Film Surface Quality in Modern Daily Disposable Contact Lens Wear
2021
Objectives As reported previously, tear film surface quality (TFSQ) should be considered in contact lens (CL) fitting. This study followed noninvasive keratograph tear film break-up time (NIKBUT) in CL wearers for 12 months to validate its clinical utility in predicting CL performance. Methods Fifty-five subjects (M/F=17/38) aged 26±4 years were prescribed silicone hydrogel or hydrogel CLs. The study included baseline measurements without CLs; 2 visits for CL fitting and control; follow-up after 3, 6, and 12 months of CL wear; and postwear visit without CLs. Ocular Surface Disease Index (OSDI), 8-Item Contact Lens Dry Eye Questionnaire (CLDEQ-8), first and mean NIKBUT (F/M-NIKBUT), fluoresc…
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…
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.
