Safety and immunomodulatory effects of three probiotic strains isolated from the feces of breast-fed infants in healthy adults: SETOPROB study.
2013
We previously described the isolation and characterization of three probiotic strains from the feces of exclusively breast-fed newborn infants: Lactobacillus paracasei CNCM I-4034, Bifidobacterium breve CNCM I-4035 and Lactobacillus rhamnosus CNCM I-4036. These strains were shown to adhere to intestinal mucus in vitro, to be sensitive to antibiotics and to resist biliary salts and low pH. In the present study, a multicenter, randomized, double-blind, placebo-controlled trial with 100 healthy volunteers in three Spanish cities was carried out to evaluate the tolerance, safety, gut colonization and immunomodulatory effects of these three probiotics. Volunteers underwent a 15-day washout perio…
Pero Tafur and Bertradon de la Broquière in Constantinople: The Ceremonial Image of Mary of Trabzond and the Diplomatic Meetings around the Council o…
2019
After the fall of Constantinople (1453), Pero Tafur and Bertrandon de La Broquière make known their works, which are two of the most important travel books written in Europe during the fifteenth century. Both travellers had known, between fifteen and twenty years before, the emperor of Greece, John VIII Palaiologos, Pope Eugene IV and other protagonists of the councils of Basel (1431-1434) and Ferrara-Florence (1438-1439), which decreed the union between the Roman and Greek churches. The travellers were, thus, witnesses, but also informants and active diplomats for the attempts of religious and political union, which Pope Pius II tried to revive after the fall of Constantinople. Tafur and L…
Penalization and data reduction of auxiliary variables in survey sampling
2012
Survey sampling techniques are quite useful in a way to estimate population parameterssuch as the population total when the large dimensional auxiliary data setis available. This thesis deals with the estimation of population total in presenceof ill-conditioned large data set.In the first chapter, we give some basic definitions that will be used in thelater chapters. The Horvitz-Thompson estimator is defined as an estimator whichdoes not use auxiliary variables. Along with, calibration technique is defined toincorporate the auxiliary variables for sake of improvement in the estimation ofpopulation totals for a fixed sample size.The second chapter is a part of a review article about ridge re…
Robust estimation of mean electricity consumption curves by sampling for small areas in presence of missing values
2017
In this thesis, we address the problem of robust estimation of mean or total electricity consumption curves by sampling in a finite population for the entire population and for small areas. We are also interested in estimating mean curves by sampling in presence of partially missing trajectories.Indeed, many studies carried out in the French electricity company EDF, for marketing or power grid management purposes, are based on the analysis of mean or total electricity consumption curves at a fine time scale, for different groups of clients sharing some common characteristics.Because of privacy issues and financial costs, it is not possible to measure the electricity consumption curve of eac…
Pero Tafur y Bertrandon de la Broquière en Constantinopla : la imagen ceremonial de María de Trebisonda y los encuentros diplomáticos en torno al con…
2018
Tras la caída de Constantinopla (1453), Pero Tafur y Bertrandon de La Broquière difunden sus libros de viajes, dos de los más importantes europeos escritos en el siglo XV. Ambos habían conocido, entre quince y veinte años antes, al emperador de Grecia, Juan VIII Paleólogo, al Papa Eugenio IV y a otros protagonistas de los concilios de Basilea (1431-1434) y Ferrara-Florencia (1438-1439), que decretaron la unión entre las iglesias romana y griega. Los viajeros fueron, así, testigos, pero también informantes y diplomáticos activos para los intentos de unión religiosa y política, que trató de reavivar el Papa Pio II tras la caída de Constantinopla (1453). Tafur y La Broquière conocieron en Cons…
Estimate the mean electricity consumption curve by survey and take auxiliary information into account
2012
In this thesis, we are interested in estimating the mean electricity consumption curve. Since the study variable is functional and storage capacities are limited or transmission cost are high survey sampling techniques are interesting alternatives to signal compression techniques. We extend, in this functional framework, estimation methods that take into account available auxiliary information and that can improve the accuracy of the Horvitz-Thompson estimator of the mean trajectory. The first approach uses the auxiliary information at the estimation stage, the mean curve is estimated using model-assisted estimators with functional linear regression models. The second method involves the au…

The paper suggest some political explanations of the recent crisis of government last summer in Italy.
Health status, diseases and vaccinations of the homeless in the city of Palermo, Italy.
2018
Introduzione. Un tempo "barboni", oggi senzatetto, il loro numero sta aumentando considerevolmente negli ultimi anni. Molti di loro soffrono di malattie croniche, problemi di salute mentale, dipendenze e necessitano di cure mediche complesse. Il loro stato di salute è spesso esacerbato per maggiori difficoltà nell'accesso alle cure primarie rispetto alla popolazione generale. Materiali e Metodi. È stato distribuito un questionario autosomministrato al fine di valutare le condizioni di salute dei senzatetto che vivono a Palermo. È stato utilizzato un modello di regressione logistica multivariata calcolando gli Odds Ratios aggiustati (aOR). Risultati. Il campione è costituito da 52 senzatetto…
Immagine urbana e qualità dello spazio nel rilievo tridimensionale di due borgate storiche palermitane
2014
Lo sviluppo dei software di rappresentazione digitale ha comportato una significativa evo- luzione dei modelli rappresentativi, aprendo contemporaneamente la strada a nuove que- stioni di natura non soltanto operativa, ma anche sostanziale. L’assenza di scala di riduzione, la tridimensionalità in “real time”, l’immersività e l’interattività dello spazio virtuale sono infatti ben più di semplici novità strumentali: si pongono come nuovi codici, introducono una visibilità simultanea e onnicomprensiva, definiscono il modello che si viene a elaborare come un “alter” dello spazio indagato, autonomo e parallelo alla realtà stessa, ben più insomma del ruolo di “model- lo” del reale al quale la rap…
Contribution à l'estimation non paramétrique des quantiles géométriques et à l'analyse des données fonctionnelles
2008
In this dissertation we study the nonparametric geometric quantile estimation, conditional geometric quantiles estimation and functional data analysis. First, we are interested to the definition of geometric quantiles. Different simulations show that Transformation-Retransformation technique should be used to estimate geometric quantiles when the distribution is not spheric. A real study shows that, data are better modelized by geometric quantiles than by marginal one's, especially when variables that make up the random vector are correlated. Then we estimate geometric quantiles when data are obtained by survey sampling techniques. First, we propose an unbaised estimator, then using lineari…
