HIV-Infected Children and Nutrition: The Friend and The Foe
2019
The impact of nutrition on HIV-infected children has been evaluated in multiple studies. Our review of the current trends of nutrition-related studies revealed that the focus has moved from simply the disease consequences of HIV to ensuring that antiretroviral therapy-treated children are well nourished to ensure growth and development. This update aims to present the state of the art regarding nutrition of HIV-infected children and the real potential for nutrition to serve as a dynamic therapy in this group. Recent World Health Organization reports indicate that the HIV/AIDS disease is curbing in incidence worldwide despite the high 1.8 million children, less than 15 years, reported in 201…
3D Data Acquisition and Numerical Analysis of a Footwear in Walking
2004
The aim of the paper is to set a procedure to study the load history of a footwear during a step with non-linear FE analysis. The geometric model tested was reconstructed from a real shoe by means of Reverse Engineering process, starting from dense point clouds acquired by non-contact scanning system. For each phase of the walk, the pressure values are obtained by a pressure distribution platform when tester is walking along the platform. The Finite Element model is easily generated by Hypermesh software using the CAD model. Ansys software is used to perform non-linear analyses. The procedure can be employed for improving the product performance in terms of durability, flexibility and comfo…
Redesign of a reverse shoulder prosthesis: Kinematic and mechanical study
2014
In this work a commercial reverse shoulder prosthesis has been redesigned to improve performances in terms of range of movements of the implant and stability to dislocation. A kinematic and mechanic study has been performed using a realistic solid model of the prothesised shoulder: in particular, all the components of the prosthesis have been acquired via a 3D laser scanner and inserted in a virtual humerus-glenoid system by reproducing the common surgical procedure. The final model has been used to measure the maximum angles of abduction and rotation of the arm and the shear forces that cause dislocation. Modifications proposed to the commercial prosthesis are: a different orientation of t…
Bacterial and viral infections and related inflammatory responses in chronic obstructive pulmonary disease
2021
Abstract In chronic obstructive pulmonary disease (COPD) patients, bacterial and viral infections play a relevant role in worsening lung function and, therefore, favour disease progression. The inflammatory response to lung infections may become a specific indication of the bacterial and viral infections. We here review data on the bacterial–viral infections and related airways and lung parenchyma inflammation in stable and exacerbated COPD, focussing our attention on the prevalent molecular pathways in these different clinical conditions. The roles of macrophages, autophagy and NETosis are also briefly discussed in the context of lung infections in COPD. Controlling their combined response…
To correct or not correct the erroneous utterances of children: teacher‐initiated organisation of repair in the L2 pre‐primary education classroom
2010
ABSTRACT The research reported on a qualitative study of feedback given in one Finnish pre‐primary education group which integrated English into the programme as a first foreign language. The study was based on the authentic video‐recorded observations of actual pre‐primary teaching sessions (N = 11 lessons). The findings suggested that the reactions of the teachers to child errors depended on the types of errors made by children. The study discussed the tension present in feedback giving when balancing between the aim of maintaining the early interest of children in language learning and the purpose of paying attention to correct ways of using the target language. The data were analysed by…

A probabilistic approach to learning a visually grounded language model through human-robot interaction
2010
A Language is among the most fascinating and complex cognitive activities that develops rapidly since the early months of infants' life. The aim of the present work is to provide a humanoid robot with cognitive, perceptual and motor skills fundamental for the acquisition of a rudimentary form of language. We present a novel probabilistic model, inspired by the findings in cognitive sciences, able to associate spoken words with their perceptually grounded meanings. The main focus is set on acquiring the meaning of various perceptual categories (e. g. red, blue, circle, above, etc.), rather than specific world entities (e. g. an apple, a toy, etc.). Our probabilistic model is based on a varia…
Les visages de l'amitié dans "Les Rougon-Macquart" d'Émile Zola
2017
Within the twenty volumes of Emile Zolas Les Rougon-Macąuart series, a number of various examples of friendship can be found. This relationship, which may be true or false, is based on diverse principles and is likely to appear as well inside a group of people as between two persons - two men, two women or a man and a woman. Sometimes it turns into a love alliance, and sometimes it disappears completely, but it is always considered as a crucial part of the diegesis.
Accès à l'éducation : quelles inégalités dans la France d'aujourd'hui ?

L'efficacité de la politique des zones d'éducation prioritaire dans les collèges
1994
This paper compares pupils progress along the first two years of middle schools fréquentation, whether these schools are in an E.P.A. or not, initial predictors of attainment being kept under control. In French and mathematics, pupils appear to have slightly weaker gains in E.P.A. than they should have elsewhere. The gap is greater for at risk pupils. E.P.A. seem to have a positive effect on pupils relation to schooling, but not on other attitudes or competenties regarding schoolwork or socialization. The E.P.A. policy effects do vary according to the schools.
