Experimental investigation on a geocontainer submerged reef

2014

Geotextile sand containers (GSC) have been used as permanent construction elements in coastal works for more than 20 years,becoming more and more popular as an alternative to the most typical coastal structures. Aim of this work is to analyze the hydrodynamic, stability and morphodynamic response of a GSC submerged reef by means of an experimental campaign. The first investigated aspect concerned the hydrodynamics. The reflection and transmission coefficients for regular and random waves were determined: the reflection coefficient decreases with increasing of kh; the transmission coefficient decreases with the increase of the incident wave. As regards the stability of the structure, it was …

Real-time 6-DOF Vessel-to-Vessel Motion Compensation using laser tracker

2017

The industry state-of-the-art offshore motion compensation is today carried out by offshore cranes equipped with Active Heave Compensation (AHC) systems, meaning that a hanging load is positioned at a certain height above the seafloor, even though the floating vessel carrying both the crane and the load is moving due to wave disturbances. Lately, there has been an increased interest among the industry also to compensate for the movement of a secondary vessel, which indicates that a more detailed investigation of the Vessel-to-Vessel Motion Compensation (VVMC) problem is required. The primary motivation for such compensation technique is influenced by the demand for load transfer between shi…

Caractérisation des effets ophtalmiques du syndrome de Cohen chez des souris VPS13B-/- et identification des mécanismes moléculaires impliqué dans la…

2020

Cohen Syndrome (CS) is a rare autosomal recessive disease caused by variations in the gene coding for the vacuolar tri-vacuolar protein 13B (VPS13B or COH1). CS patients have common features including typical facial appearance, neutropenia, abnormal trunk fat distribution, microcephaly, myopia and retinal damage. My thesis project aimed to characterize the ophthalmologic phenotype of a mouse model Vps13bEx3/Ex3 to determine the molecular mechanisms involved in the development of CS retinopathy.First, we showed that Vps13bEx3/Ex3 mice develop a cataract between 2 and 3 months. Disorganization of the fibrous cells of the crystalline lens and their differentiation into mesenchymal cells were o…

Chartae Burgundiae Medii Aevi (CBMA). Du parchemin à l'écran

2013

International audience; Produits par centaines de milliers au Moyen Âge, les actes diplomatiques1 sont probablement les sources les plus mobilisées par une tradition historiographique ancienne de plus de trois siècles. Ils ont été depuis souvent édités et font partie des premiers documents médiévaux à être soumis à des traitements informatiques, dès les années 1970, pour alimenter plus tard des bases de données. S'insérant dans ce contexte, lors de son lancement en 2004, le projet des CBMA2 était forcément électronique, mais aussi, développements technologiques obligent, forcément voué à la diffusion libre et immédiate sur Internet. Le projet envisageait la numérisation, l'enregistrement et…

L'échange dans la documentation diplomatique bourguignonne : autour du vocabulaire des transferts

2013

Cette étude propose une approche du vocabulaire des transferts à partir d'une masse importante de documents diplomatiques médiévaux (VIIIe-XIIIe siècle), réunis principalement au sein de la base des données des CBMA (Chartae Burgundiae Medii Aevi - http://www.artehis-cbma.eu/) soumise au traitement du logiciel Philologic, et mise en regard par rapport aux différentes catégories de sources publiées dans la Patrologie latine. L'analyse de la fréquence et des cooccurrences des formes et dérivés de commutatio, cambio, permutatio a permis de dégager les tendances générales qui concernent et articulent entre eux, le champ sémantique des transferts (la proximité des mots désignant différents types…

A fiber-based limiter at 170 Gbit/s for all-optical regeneration

2009

We report the numerical and experimental studies of a spectrally filtered fiber-based optical limiter at 170 Gbit/s. The device, including less than 1 km-long of highly nonlinear optical fiber and a 3 nm-width filter, exhibits good performance at an average input power of 14.5 dBm. No power penalty has been observed and a strong robustness against optical noise has been demonstrated.

ECONOMIC EVALUATION OF AQUACULTURE INVESTMENTS UNDER CONDITIONS OF RISK AND UNCERTAINTY IN THE MEDITERRANEAN SEA

2014

This study aims to analyze, from a technical and ec onomic point of view, the choice between alternative investments in aquaculture under condit ions of risk and uncertainty. In particular, a comparative analysis has been conducted between an inshore and an offshore farm producing European sea bass in the Mediterranean Sea. The app lied model refers to the theory of subjective probability, assigning a different probability to e xpected incomes during the investment period. Resul ts show an economic convenience of inshore with respect to offshore farming.

impact of dietary intake of n-3 polyunsaturated fatty acids on the physiology of the peripheral olfactory system in young mice

2021

Abstract : Olfaction plays a major role in the detection of volatile chemical signals present in the environment and triggers behaviors such as food intake, social interactions or danger avoidance. Recent studies suggested that nutritional and metabolic status of individuals may influence their olfactory capacities. Olfactory disorders have been observed in people with pathologies such as obesity and diabetes as well as in rodents exposed to obesogenic or diabetogenic diets. The physiological mechanisms underlying these dysfunctions are not known. One hypothesis is that a nutritional imbalance in lipids might alter the functioning of the peripheral olfactory system. In this context, the obj…
