Impact of Bacterial Siderophores on Iron Status and Ionome in Pea
2020
National audience; Including more grain legumes in cropping systems is important for the development of agroecological practices and the diversification of protein sources for human and animal consumption. Grain legume yield and quality is impacted by abiotic stresses resulting from fluctuating availabilities in essential nutrients such as iron deficiency chlorosis (IDC). Promoting plant iron nutrition could mitigate IDC that currently impedes legume cultivation in calcareous soils, and increase the iron content of legume seeds and its bioavailability. There is growing evidence that plant microbiota contribute to plant iron nutrition and might account for variations in the sensitivity of pe…
APPLICAZIONE DI CRITERI E INDICATORI DELLA CERTIFICAZIONE PEFC DI GESTIONE FORESTALE SOSTENIBILE: DUE CASI STUDIO A CONFRONTO NEL TERRITORIO SICILIANO
2018
La Sicilia non ha ancora complessi forestali la cui gestione sostenibile sia stata certificata. Questo lavoro è volto a analizzare la possibilità di applicare i criteri e indicatori di certificazione di GFS secondo lo schema PEFC a due casi studio: i boschi del comune di Bivona (AG) e una foresta situata sulle Madonie (PA). Entrambi sono rappresentativi di ambienti ecologici diversi e importanti dell’isola. L’analisi pone in luce le criticità più significative della gestione attualmente adottata e la mancanza di comunicazione con i portatori d’interesse.

Does the association of therapeutic exercise and supplementation with sucrosomial magnesium improve posture and balance and prevent the risk of new f…
2021
Abstract Background Fracture of the proximal femur is the most feared complication of osteoporosis. Given the numerous physiological functions that magnesium performs in our body, in the literature there is a correlation between osteoporosis and low serum levels of magnesium. Aim Evaluate the incidence of hypomagnesemia in patients with lateral fragility fracture of the proximal femur, the possible correlation between serum magnesium levels and fractures, and the effectiveness of supplementing Sucrosomial® magnesium associated with therapeutic exercise on the outcome of these patients. Methods We divided the study into two parts. In the first part, we assessed the preoperative incidence of …
Towards sustainable production of minerals and chemicals through seawater brine treatment using Eutectic freeze crystallization and Electrodialysis w…
2022
European policy encourages the adoption of sustainable systems that promote the efficient use and recovery of minerals and chemicals. In this respect, desalination brines do contain a dramatic amount of valuable minerals and can be valorized through appropriate treatments rather than releasing them into the environment. This paper proposes an innovative brine recovery system for obtaining high purity chemicals through the integration of Eutectic Freeze Crystallization (EFC) and Electrodialysis with Bipolar Membrane (EDBM) technologies. Two separate laboratory-scale experimental campaigns were carried out to validate the potential integration of the two processes. Mirabilite (Na2SO4∙10H2O) h…
Evaluation, Analysis and Perception of Sustainable Forest Management Through the Lens of the PEFC Forest Certification Using Two Case Studies in Sici…
2019
Sustainable forest management has reached a common understanding between scientific and technical definitions. A series of criteria and indicators have been implemented for monitoring the effectiveness of the management in functional and structural terms, and to evaluate its effects on ecosystem services of forests. Currently, Sicily has no forest areas with certification of sustainable forest management and in order to evaluate the diffusion of knowledge of certification schemes and their importance in SFM, a questionnaire survey was carried out during a foresters' workshop on the island. The possibility of applying the criteria and indicators of PEFC certification of sustainable forest ma…
APPLICAZIONE DI CRITERI E INDICATORI DELLA CERTIFICAZIONE PEFC DI GESTIONE FORESTALE SOSTENIBILE: DUE CASI STUDIO A CONFRONTO NEL TERRITORIO SICILIANO
2018
Sicily currently has no forest areas with certification of sustainable forest management. This work analyzes the possibility of applying the criteria and indicators of PEFC certification of sustainable forest management in two study-cases: the municipal forest of Bivona (AG) and a forest area in the Madonie Mountains (PA). Both are representative of different and important Sicilian forest ecosystems. This analysis highlights the main weaknesses related to current forest management practices and the inadequate consultation with stakeholders.
Structural and electrochemical investigation on re-cast Nafion membranes for polymer electrolyte fuel cells (PEFCs) application
2006
Abstract Starting from a 5 wt% ion power Nafion® solution and dissolving the dry residue in a suitable solvent (10 wt% solution in dimethylacetammide), re-cast Nafion films were developed for polymer electrolyte fuel cells (PEFCs) application. The used Doctor-Blade casting technique allowed to prepare scaled-up membranes comparable to the commercial Nafion ones with good mechanical resistance, thickness homogeneity and an excellent reproducibility. The differences between the re-cast membrane nanostructure and that of the commercial Nafion were investigated by synchrotron small-angle X-ray scattering. The obtained re-cast membrane shows at ambient conditions a semi-crystalline structure wit…
Can the certification of cork management agroforestry system in Sicily help to relaunch its future management?
2019
The economic importance of cork oak forests is mainly attributable to the role of provisioning non-timber forest products. The history of human management of these cork oaks stands make them a perfect example of agroforestry system, which surface is totally included in the Mediterranean-climate zones with more than 2.3 million hectares. In Sicily, the surface covered by cork forests amounts to about 15,000 ha but the most of this area is not affected by cultural practices. The cultural abandonment of many cork oak stands threatens their survival because of the close link between the conservation of cork stands and its use for productive purposes. The abandonment reasons are related to poor …

Valorization of seawater desalination brines through the integration of Eutectic Freeze Crystallization and Electrodialysis with Bipolar Membranes in…
2021
European policy encourages the adoption of sustainable systems that promote the efficient use and recovery of resources. Accordingly, this study proposes integrating two innovative technologies, including Eutectic Freeze Crystallization (EFC) and Electrodialysis with Bipolar Membranes (EDBM), for treating seawater desalination brines. Two experimental campaigns were conducted to assess the viability of this novel treatment chain. Using two lab-test rig units, the effect of various operating conditions on the outputs and general performance of both EFC and EDBM was evaluated. Firstly, results showed that EFC could manage seawater brines to (i) obtain pure sodium sulphate, and fresh water in …
