VALORIZATION OF ANCHOVY FISHBONE WASTES FOR THE PREPARATION OF BIOPOLYMERIC BASED GREEN COMPOSITES FOR FOOD PACKAGING APPLICATIONS
Temas e interpretaciones del derecho sucesorio italiano
2021
El articulo quiere mostrar que las interpretaciones de las instituciones del derecho de sucesiones que consideran el interés familiar, como expresión del principio de solidaridad (cada vez más en una protección patrimonialista de la legitimidad), siempre prevalente sobre todos los demás intereses, ya no pueden ser compartidas, porque la solidaridad no se distingue del personalismo. Modernizar el derecho de sucesiones no significa tener que abdicar en favor del contrato, sino descubrir el valor de la autonomía privada y el potencial del acto de última voluntad. Es la centralidad de la persona humana y no sólo el principio de solidaridad (más aún si se entiende en un sentido patrimonialista) …
Energy harvesting by waste acid/base neutralization via bipolar membrane reverse electrodialysis
2020
Bipolar Membrane Reverse Electrodialysis (BMRED) can be used to produce electricity exploiting acid-base neutralization, thus representing a valuable route in reusing waste streams. The present work investigates the performance of a lab-scale BMRED module under several operating conditions. By feeding the stack with 1 M HCl and NaOH streams, a maximum power density of ~17 W m−2 was obtained at 100 A m−2 with a 10-triplet stack with a flow velocity of 1 cm s−1, while an energy density of ~10 kWh m−3 acid could be extracted by a complete neutralization. Parasitic currents along feed and drain manifolds significantly affected the performance of the stack when equipped with a higher number of t…
A simulation tool for ion exchange membrane crystallization of magnesium hydroxide from waste brine
2021
Abstract Increasing attention is nowadays paid to the management and valorisation of industrial waste brines aiming also at the recovery of raw materials. Magnesium has been listed as a Critical Raw Material by EU, prompting researchers to investigate novel routes for its recovery. Within this framework, a novel Crystallizer with Ion Exchange Membrane (CrIEM), is proposed as an innovative way to recover magnesium from industrial waste brines exploiting low-cost alkaline reactants. In the present work, a novel mathematical model of the CrIEM process is proposed to provide a useful tool for its design in different working conditions. Batch and feed & bleed continuous configurations have been …
L’allevamento bovino nella valle del Torto: un caso di zootecnia sostenibile in Sicilia
2011
In spite of not being the main activities of Sicilian agriculture, zootechny plays a very important social role, even more than economic, for a large part of Sicily. The crisis that has hit the industry since early 2000s, and particularly cattle livestock, caused the closure of many holdings and a strong decrease in the number of animals bred, both meat and dairy cattle. The beef cattle population in the Valle del Torto, in the province of Palermo (area covered by this study), for many decades has significantly contributed to the development of a rural community that trough this activity created his own wealth, income and economic stability. The crisis that over the last decade has affected…
Comunicazione e divulgazione della ricerca scientifica applicata all’archeologia : il punto di vista degli young researchers
2017
International audience; What is the relationship between science and communication? And how important are cultural dissemination tools for the research survival? Recently, the archaeological study has undergone a substantial change, thanks to the introduction of non-invasive digital surveying techniques as well as physical and chemical analyses. It became therefore necessary to form a new archaeologist able to use them and to dialogue with new professional figures that move in the same direction. Also, it’s essential to promote the communication expert figures, which linked the scientific world and the public at large. Actually, Digital storytelling is a learning tool increasingly used by m…
Showing the Invisible: The Economic Cycle of Stone Tools
2023
This contribution takes place in a broader theme, that of “the invisible economy of recyclable materials”. It aims to illustrate the phenomena of recovery of materials from lithic tools and their consequences. The classification of tools by material, although classic, is not relevant from a technical point of view. The material of a tool, in particular its mechanical properties, is to be taken into consideration in its technical analysis, but it cannot constitute a determining criterion in a classification system. Function should come first, as most functional categories use multiple materials. The most striking example, if one can say so, is that of the striking supports, where one finds, …
La nuit étoilée, nouvel horizon des rapports des territoires à l’environnement
2015
International audience; Longtemps resté confidentiel, le thème de la nuit suscite de plus en plus d'intérêt aux yeux des chercheurs en sciences sociales du fait de son entrée dans les débats sur l'aménagement et le développement des territoires. La protection et la valorisation du ciel étoilé apparaissent ainsi comme de nouvelles potentialités d'attractivité tout en élargissant la réflexion et le regard sur les enjeux environnementaux.

La valorisation des compétences de base sur le marché du travail
2012
Dans la théorie du capital humain, les individus sont rémunérés selon leur productivité, productivité qui dépend elle-même du niveau de diplôme ou du nombre d'années d'études. Mais à l'heure où l'éducation certifiée est discutée comme signal, qu'en est-il de la valorisation des compétences, notamment de base, en tant que " nouveau signal " ? Ce présent travail cherche alors à déterminer dans quelle mesure les salaires sont expliqués par le niveau de littératie, de numératie et de compréhension orale.
