CURRENT ROOTSTOCK USE AND ROOTSTOCK NEEDS FOR THE FUTURE: SOUTHERN ITALY, SICILY AND ARID MEDITERRANEAN AREAS

2013

Grapevine rootstocks have been an essential component of grape growing for over 150 years as rootstocks can impart desirable characteristics for grapevine growth. This review examined Italian and Sicilian literature on rootstocks, focusing on key issues including updates on needs for the future. Other related issues include the performance of major selection traits associated with salinity, drought, potassium uptake, vegetative growth, grape and wine quality and the propagation of grafted vines. Research on rootstocks started in Italy, and of course in other European Countries, once phylloxera was imported. In Italy, phylloxera was detected in Agrate (north Italy) in August 1879, but it may…

Integrated analysis of performances of facades for indoor comfort purposes

2002

Some guidelines for a method able to evaluate different physical characteristics of building facades, equipped with glazed surfaces, and of indoor environments in order to attain indoor comfort conditions are proposed. New graphs are introduced, showing at the same time the behaviours of several technical-physical parameters of walls, in order to allow comparative analysis of different design configurations in terms of acoustics, lighting and heat transfer properties. Similar graphs are also constructed with reference to parameters characteristic of indoor environment, in order to allow synthetic analysis of comfort conditions. The method would represent a contribution toward the definition…

Production of written French skills by first generation immigrants in working age

2013

This paper aims to identify factors explaining the level of proficiency in written French by immigrants in working age, knowing that few research has been conducted in France on this issue. The originality of this paper is the stochastic production frontier model to explain the scores in written French and the productive performance of immigrants (considered as producers of their own skills). The main results show that mother tongue, age at immigration, social life and mother's diploma are elements which influence the effectiveness of this production. They play a crucial role in the ability of immigrants to use effectively their duration of stay in France and their length of education, cons…

Design Procedures for Soil-Lime Stabilization for Road and Railway Embankments. Part 1-Review of Design Methods

2012

AbstractWhen selecting the appropriate materials for constructing road infrastructures, an important way for minimizing both the economical and environmental impact is to make use of lime for treating soils that are not suitable for road or railways construction.Advances in lime stabilization technique allowed the successful use of this technique also for improving the bearing capacity of the subgrade, with noticeable savings on both aggregate and disposal charges.In this paper a review of internationally adopted design methods for soil-lime mixture is presented, in order to compare testing methods and requirements of the adopted criteria, as discussed in Part 2.

Design Procedures for Soil-Lime Stabilization for Road and Railway Embankments. Part 2-Experimental Validation

2012

AbstractAs detailed in Part 1, the most common Italian Technical Specifications refer to different design methodologies for design of lime-soil mixtures, some being quite different from those internationally adopted. Therefore, it seemed appropriate to the Authors to compare these methodologies, via a wide experimental program.It is shown that the Italian methodology of the National Road Agency is different not only from those used in Italy, but also from the main international standards. The experimental results highlight that a revision of that methodology is needed in order to bring it into line with what is prescribed by the European standard.

Prise en eau par composites carbone/époxy et leur effet sur le comportement mécanique : application aux réparations de structures en composite par co…

2013

Le travail présenté dans ce mémoire avait pour objectif d’étudier le processus de la pénétration d'eau dans les composites en carbone/époxyde dans un premier temps, et dans un deuxième temps, d’étudier l’effet de la prise en eau par ces matériaux sur les performances mécaniques des composites et leur joints collés. L'intégration de ces phénomènes physiques dans la modélisation numérique est d'une grande importance dans la prédiction de la durabilité d’une structure en composite subissant un vieillissement hygrothermique. Par conséquent, ce travail consiste non seulement en des observations expérimentales, mais aussi en des simulations numériques. Des corrélations entre les résultats obtenus…
