Emerging Cyber risk Challenges in Maritime Transportation
2022
Maritime security and surveillance have become one of the main areas in managing overall situational awareness. For example, the growing importance of maritime traffic in cross-border trade has created new pressures to develop new technologies for accident prevention, especially in the ports. Maritime safety is also a matter of concern for continuity management. Automatic ship alarm systems, coastal radars and coastal cameras are not alone sufficient equipment to build maritime awareness. The Universal Shipborne Automatic Identification System (AIS) is a ship transponder system that is a globally used tracking system, but highly vulnerable to hacking. A major maritime traffic problem arises…

Enhancing the Iterative Smoothed Particle Hydrodynamics Method
2021
Motivated by recent research on the iterative approach proposed for the smoothed particle hydrodynamics (ISPH) method, some ideas to improve the process are introduced. The standard procedure is enhanced iterating on the residuals preserving the matrix-free nature of the process. The method is appealing providing reasonable results with disordered data distribution too and no kernel variations are needed in the approximation. This work moves forward with a novel formulation requiring a lower number of iterations to reach a desired accuracy. The computational procedure is described and some results are introduced to appreciate the proposed formulation.
Dalla cultura dei parvenu alla cultura del capitale sociale. Terzo settore e società civile in Sicilia
2006
Avvalendosi di un questionario già predisposto a livello nazionale, il contributo ricostituisce il panorama del terzo settore nell’area periferica di Trapani, sottolineando la capacità di una parte delle Ots di promuovere una reale autonomia della società civile, malgrado per un terzo delle stesse sia ancora forte la dipendenza dai finanziamenti pubblici, e quindi dai partiti che gestiscono la pubblica amministrazione locale. L’autrice sostiene infatti che in Sicilia se «il mondo del privato sociale, da un lato, abbia offerto una sponda alla “cultura civile del lavoro”, dall’altro abbia affermato una cultura e una pratica delle relazioni che emerge prepotentemente dagli anfratti della matri…
Extraordinary Performance of Carbon‐Coated Anatase TiO 2 as Sodium‐Ion Anode
2015
The synthesis of in situ polymer‐functionalized anatase TiO2 particles using an anchoring block copolymer with hydroxamate as coordinating species is reported, which yields nanoparticles (≈11 nm) in multigram scale. Thermal annealing converts the polymer brushes into a uniform and homogeneous carbon coating as proven by high resolution transmission electron microscopy and Raman spectroscopy. The strong impact of particle size as well as carbon coating on the electrochemical performance of anatase TiO2 is demonstrated. Downsizing the particles leads to higher reversible uptake/release of sodium cations per formula unit TiO2 (e.g., 0.72 eq. Na+ (11 nm) vs only 0.56 eq. Na+ (40 nm)) while the …
Influence of Calcium Carbonate Nanoparticles on the Soil Burial Degradation of Polybutyleneadipate-Co-Butylenetherephthalate Films.
2022
A polybutyleneadipate-co-butylenetherephthalate (PBAT) sample, commercially known as Ecoflex®, was processed via melt extrusion with CaCO3 nanoparticles coated with a hydrophobic coating. Blown films of PBAT and two composites with nanofiller (2% and 5%wt) were prepared and degradation tests in soil at 30 °C up to 180 days were carried out with weight loss measurements. Furthermore, biodegradation test according to ISO 14851 was carried out at 30 °C. The effect of CaCO3 on soil burial degradation was assessed by surface wettability and SEM. ATR-FTIR and XPS analyses highlighted chemical modifications induced by soil degradation. CaCO3 nanoparticles decreased surface wettability …
Functional molecular materials: supramolecular networks and coordination polymers with optical and/or magnetic properties
2020
El camp dels materials moleculars atrau l’atenció de molts científics degut al gran potencial de la química molecular en el disseny de materials amb un ajust precís de les seues propietats. Els dos projectes tractats en aquesta tesi representen dos temes que destaquen en aquesta àrea, materials de transició d’espín i polímers de coordinació amb propietats òptiques i/o magnètiques, gràcies al seu significant progrés i ràpid desenvolupament en els últims anys. La primera part d’aquesta tesi es basa en l’ús d’enllaços d’hidrogen en el disseny de xarxes multifuncionals de ferro(II) amb transicions d’espín abruptes. El capítol 1 és una introducció a aquest tema des de la perspectiva dels complex…
A Critical Review of Relations between Corporate Responsibility Research and Practice
2007
This essay identifies epistemological, theoretical and methodological problems in a potentially influential subset of the interdisciplinary corporate responsibility literature, that which appears in the management literature. The received conceptualization of stakeholder analysis is criticised by identifying six sets of factors conventionally considered as promoting social responsibilities in the firm: inter-organizational factors, economic competitors, institutional investors, end-consumers, government regulators and non-governmental organizations. Each is addressed on conceptual grounds, its empirical salience in terms of the latest relevant research and prospects to be a significant fact…
