Les dispositifs de prise en charge de la difficulté scolaire à l’école élémentaire : étude de leur fonctionnement et de leurs effets sur la réussite …

2018

With the Jules Ferry laws ensuring free and compulsory schooling, equal chances of succeeding were expected in a meritocratic established school system. Reality proved otherwise: attending school still does not allow all schoolchildren to progress in the same way, as some of them encounter difficulties from the beginning. The struggle against academic failure cannot stop a considerable amount of pupils from finishing school without satisfactorily mastering the basic elements of the programmes. Moreover, recent research works have seemed to prove programmes providing assistance for underachievers to be ineffective.This thesis offers a comparative evaluation of such support systems in element…

Lead(II) ions adsorption onto amyloid particulates: An in depth study

2022

The production of new cost-effective biocompatible sorbent sustainable materials, with natural origins, able to remove heavy metals from water resources is nowadays highly desirable in order to reduce pollution and increase clean water availability. In this context, self-assembled protein materials with amyloid structures seem to have a great potential as natural platform for a broader development of highly-tunable structures. In this work we show how protein particulates, a generic form of protein aggregates, with spherical micro sized shape can be used as adsorbents of Pb2+ ions from aqueous solution. The effect of pH, ionic medium, ionic strength and temperature of the metal ion solution…

Las ADR en la justicia del siglo XXI, en especial la mediación (The Alternative Dispute Resolution ‘ADR’ in the Justice of the 21st Century, Especial…

2011

Spanish Abstract: El presente ensayo busca exponer en torno a experiencias poco analizadas por los sistemas juridicos europeos de corte continental, pero muy bien conocidas por los sistemas anglosajones. El objetivo trazado es fomentar el debate en torno a estas alternativas para la resolucion de los conflictos en la sociedad, con especial atencion a la mediacion. English Abstract: This is essay seeks to expose not very much analyzed experiences by the legal systems of the continental Europeans, but very well known by the Anglo-Saxon systems. The stated goal is to encourage debate on these alternatives to resolve conflicts in society, with special attention to mediation.

Ex situ conservation and exploitation of fungi in Italy

2011

Abstract The kingdom Fungi comprises one of the most diverse groups of living organisms. They are numerous, ubiquitous and undertake many roles both independently and in association with other organisms. Fungi display a wide diversity of forms also mirrored by functional diversity and play such a dominant role in human society that they are arguably biotechnologically the most important group of organisms. Ex situ conservation of fungi, not only guarantees correct management and conservation of biodiversity, but also its exploitation in different fields. This article describes the major biological resource centres dealing with fungi in Italy and gives several examples of fungal exploitation…

Human Resources Management Practices Perception and Extra-Role Behaviors: The Role of Employability and Learning at Work

2021

Human Resource Management (HRM) processes are considered the beating heart of any successful organization. Recently, several studies have highlighted how organizations can use commitment-oriented HR practices to generate organizational and individual effectiveness. The aim of this study was to verify whether the perception of HRM practices could be able to elicit extra-role behaviors and, at the same time, whether this relationship could be mediated by employability and learning conditions. The analyses were carried out on a sample of 1219 Italian workers using Structural Equation Models. The structural model yielded good fit indices and the results showed a significant and positive effect …

Laccase: A Review of Its Past and Its Future in Bioremediation

2011

Laccases are multicopper proteins that use molecular oxygen to oxidize a broad spectrum of organic compounds by a radical-catalyzed reaction mechanism. Many articles over the past 15 years have touted the diverse potential applications of laccase in various biotechnological processes. This review covers the natural roles of the enzyme, its structural properties, substrates, reaction mechanism, and inhibitors, as well as its applications regarding the detoxification and bioremediation of polluted wastewaters and soils. Other applications are briefly covered as well. The authors critically assess the advantages, shortcomings, and future needs relating to laccase availability, effectiveness, a…

Mercury(II) removal from aqueous solution by sorption onto alginate, pectate and polygalacturonate calcium gel beads. A kinetic and speciation based …

2013

Abstract Gel beads of calcium alginate, pectate and polygalacturonate salts have been tested as sorbent materials for mercury(II) removal from aqueous solutions. Physico-chemical properties of gel beads, defined by SEM–EDX, TGA and texture and density analysis, were correlated with gel beads sorption capacity towards Hg 2+ ion. A speciation study in aqueous solution was carried out to define the strength of interaction of mercury ion with the polymers investigated and to assess the more suitable experimental conditions to achieve the best effectiveness of Hg 2+ sorption by gel beads. On the basis of the speciation study, pH values in the 3–5.5 pH range were considered appropriated for mercu…

Sorption of Pd(II) ion by calcium alginate gel beads at different chloride concentrations and pH. A kinetic and equilibrium study

2016

Abstract A kinetic and thermodynamic study on the sorption ability of calcium alginate gel beads towards Pd(II) ion was made in aqueous solution at different pH and chloride concentrations. The experimental conditions adopted in the sorption experiments were established on the basis of a speciation study on the Pd 2+ -AA system in which all the side reactions, such as the hydrolysis of Pd(II), the protonation of alginate and the interactions of the ligand and the metal ion with ions of ionic medium were taken into account. In the pH range 2–5 and at chloride concentration in the range 0 ⩽ C Cl - /mmol L −1  ⩽ 10 the gel beads showed good sorption ability towards Pd(II) ion as confirmed by k…

Removal of Cypermethrin from Water by Using Fucus Spiralis Marine Alga

2019

Alpha-cypermethrin is a synthetic pyrethroid that was extensively used for insect control, since the early 1980s. However, it is known that its presence in the environment has toxic effects on humans and aquatic life forms. For this reason, it is commendable for it to be removed completely from the contaminated environment. In this study, we evaluated the adsorption capacity of a marine alga for the removal of cypermethrin from water. The adsorption experiments were performed based on the batch equilibrium technique. The samples containing the pesticide were analyzed using gas chromatography with an electron capture detector, after liquid-liquid extraction in hexane. The results obtained fr…
