Feasibility analysis and study of a grid-connected hybrid electric system: Application in the building sector
2016
This paper represents the feasibility study and analysis of a grid-connected hybrid (PV-Wind) system with battery, realized within the project DE.DU.ENER.T and installed in the research centre CRTEn located in the northern Tunisia in the city of Borj-Cedria. The main objective of this work is to exploit renewable sources of electrical energy production to electrify the desired building. So, to minimize electricity consumption costs, reduce the adverse effects of pollutants products from the diesel power systems and sometimes happen to sell the surplus of energy produced. The HOMER (Hybrid Optimization Model of Electric Renewable) software is used to estimate system size and its performance …
Influence of doped charge transport layers on efficient perovskite solar cells
2018
Planar vacuum deposited p–i–n methyl ammonium lead tri-iodide perovskite solar cells are prepared with different electron and hole transporting layers, either doped or undoped. The effect of these layers on the solar cells performance (efficiency and stability) is studied. The main benefit of using doped layers lies in the formation of barrier free charge extraction contacts to the electrodes. However, this comes at the cost of increased residual absorption (reducing the current density and efficiency of the cells) and a decreased stability. A generic solar cell structure using undoped charge extraction layers is presented, containing a thin layer of a strong electron acceptor in between th…

Notes on Using the Hidden Asset or the Contribution Asset to Compile the Actuarial Balance for Pay-as-You-Go Pension Systems
2010
The aim of this paper is twofold: to determine the connection between the “contribution asset” and the “hidden asset” and to discover whether using either of them to compile the actuarial balance in Swedish-type pay-as-you-go pension systems will provide a reliable solvency indicator. We develop an overlapping generations model and apply it to the defined benefit pay-as-you-go system, although it would be just as valid for NDC systems. On the theoretical side the main conclusion is that, despite their very different natures, in a simplified scenario the contribution asset and the hidden asset could coincide if r - the real rate of interest - is equal to the growth in the wage bill. On the a…
Development of a Multifunctional Bioerodible Nanocomposite Containing Metronidazole and Curcumin to Apply on L-PRF Clot to Promote Tissue Regeneratio…
2020
Teeth extractions are often followed by alveolar bone reabsorption, although an adequate level of bone is required for reliable rehabilitations by dental implants. Leukocyte and platelet-rich fibrin (L-PRF) has been widely applied in regenerative procedures and with antibiotic and antioxidant agents could play an essential role in hard and soft tissue healing. In this work, a nanocomposite (Sponge-C-MTR) consisting of a hyaluronate-based sponge loaded with metronidazole (MTR) and nanostructured lipid carriers containing curcumin (CUR-NLC) was designed to be wrapped in the L-PRF&trade
L’ESPERIENZA DEL PNRR: LE FONTI DEL DIRITTO DAL POLICENTRISMO ALLA NORMAZIONE EURO-GOVERNATIVA
2022
The A. gives an overview of the Euro-National normative framework under which the National Plan of Recovery and Resilience of the Italian State (NPRR) hase been developed and it is implemented. The core of the analysis is the impact of EU norms regulating Next generation EU and the Recovery and Resilience Facility on the Italian Constitutional "order" of sources of Law. It is dedicated particular attention to the "legislative measures" defined in the NPRR, the system of evaluation of compliance to the Plan concerning those measures and the normative "practice" of its implementation. The main target of the research is to evaluate if both the pandemic emergency and the legal responses, among …
Urban rehabilitation areas in Oporto, Portugal. A brief overview
2020
This paper establishes some preliminary outcomes of the research period carried in 2019 at CITTA – University of Porto as a visiting student. Oporto is the second largest Portuguese city and the engine of the metropolitan system of the northern region of the country. For more than 30 years local urban policies have been articulated with the EU urban policies to deal with severe urban problems and boost regeneration processes. Whilst the PhD research project is entitled – Understanding the EU’s urban agenda at the margins of Europe: lessons and perspectives – studying the case of Oporto is an opportunity to reflect on the influence and impact of the EU’s regional policy over the trajectories…
Identification and quantification of phosphatidylcholines containing very-long-chain polyunsaturated fatty acid in bovine and human retina using liqu…
2010
The retina is one of the vertebrate tissues with the highest content in polyunsaturated fatty acids (PUFA). A large proportion of retinal phospholipids, especially those found in photoreceptor membranes, are dipolyunsaturated molecular species. Among them, dipolyunsaturated phosphatidylcholine (PC) molecular species are known to contain very-long-chain polyunsaturated fatty acids (VLC-PUFA) from the n-3 and n-6 series having 24-36 carbon atoms (C24-C36) and four to six double bonds. Recent interest in the role played by VLC-PUFA arose from the findings that a protein called elongation of very-long-chain fatty acids 4 (ELOVL4) is involved in their biosynthesis and that mutations in the ELOVL…
Measurement technique for real-time and low-cost biosensing using photonic bandgap structures
2011
We present a sensing technique based on using photonic bandgap structures where only the output power is monitored, without the need of tunable sources or spectrum analyzers, thus providing a real-time and low-cost system.
Rappresentare il cambiamento. Street art e rigenerazione urbana a Palermo
2018
Da qualche anno Palermo è oggetto di attenzione da parte di artisti che, da varie parti del mondo, hanno scelto la città quale luogo delle proprie sperimentazioni. Tale fermento ha visto il proliferare di interventi di street art, spesso strumenti di denuncia sociale, in edifici abbandonati, zone urbane degradate, lottizzazioni abusive o edificazioni a ridosso della linea di costa. Recently Palermo is the subject of attention by artists who, from various parts of the world, have chosen the city as the place of their experimentations.This ferment has seen the proliferation of street art, often instruments of social denunciation, realised in abandoned buildings, degraded urban areas, illegal …
