Fractional visco-elastic Timoshenko beam deflection via single equation

2015

This paper deals with the response determination of a visco-elastic Timoshenko beam under static loading condition and taking into account fractional calculus. In particular, the fractional derivative terms arise from representing constitutive behavior of the visco-elastic material. Further, taking advantages of the Mellin transform method recently developed for the solution of fractional differential equation, the problem of fractional Timoshenko beam model is assessed in time domain without invoking the Laplace-transforms as usual. Further, solution provided by the Mellin transform procedure will be compared with classical Central Difference scheme one, based on the Grunwald-Letnikov appr…

Un'applicazione della Social Network Analisys alla rete di relazioni di un Gruppo d’Acquisto Solidale: l’esperienza di Gasualmente

2012

The phenomenon of GAS (Solidarity Purchase Groups) in Sicily has in Gasualmente an important actor. This GAS, was created following a structured training program and research by the Faculty of Agriculture of the University of Palermo. It now plays an important role as activator of relationships and ethical affirmation of critical consumption, and promotion of organic products. The study aims through the Social Network Analysis, to investigate Gasualmente network and the role played by all the actors involved.

Study of new tellurite glasses in the TeO2-ZnO-La2O3 (TZL) system for the manufacturing of mid-infrared multimaterial optical fibers and specialty op…

2023

This thesis work was carried out using tellurite glasses from the TeO2-ZnO-La2O3 (TZL) ternary diagram for optical fibers manufacturing. The choice to use this system is motivated by the ambition to improve the transmission of optical signals within oxide glasses for which absorption bands related to OH groups are present in the transparency window. A structural study is first carried out on these glasses by Raman spectroscopy in order to understand the influence of the composition on physicochemical properties (especially on optical and thermal properties) but also to estimate the ability of a vitreous matrix to reorganize when subjected to a thermal solicitation such as the preform-to-fib…

When does Regression discontinuity design work? Evidence from random election outcomes

2018

We use elections data in which a large number of ties in vote counts between candidates are resolved via a lottery to study the personal incumbency advantage. We benchmark non‐experimental regression discontinuity design (RDD) estimates against the estimate produced by this experiment that takes place exactly at the cutoff. The experimental estimate suggests that there is no personal incumbency advantage. In contrast, conventional local polynomial RDD estimates suggest a moderate and statistically significant effect. Bias‐corrected RDD estimates that apply robust inference are, however, in line with the experimental estimate. Therefore, state‐of‐the‐art implementation of RDD can meet the re…

EU income stabilization tool: potential impacts, financial sustainability and farmer’s risk aversion

2021

AbstractThe Income Stabilization Tool, a risk management scheme introduced within the Common Agricultural Policy (CAP) 2014–2020, could help European Union farmers manage the income risks they face. This study assesses the potential impact of implementing this tool through the maximum level of contribution to the fund which determines an indifference to participate in the fund and its financial sustainability. The study relies on an expected utility approach and assesses the variability of loss ratios over time using a sample of Italian hazelnut farms as a case study. The participation depends on the level of farmers' contributions and their degree of risk aversion. However, the CAP public …

Interactions between Street Food and Food Safety Topics in the Scientific Literature—A Bibliometric Analysis with Science Mapping

2022

Street food (SF) consists of ready-to-eat food prepared and sold on the street. This food constitutes the food traditions of local populations in many countries of the world. SF characterizes a large number of cities around the world, from New York to Paris, from Palermo to cities of North Africa, China, India and Japan. SF is inexpensive and prepared following traditional methods that meet local consumer preferences, culinary culture and lifestyles. Moreover, SF allows a unique experience for tourists who also want to experience a destination through traditional food consumed on the street together with the locals. Nevertheless, SF is linked to several health hazards. Hence, several studie…

The Experiences and Views on Palliative Care of Older People with Multimorbidities, Their Family Caregivers and Professionals in a Spanish Hospital

2022

The increasing prevalence of complex chronic diseases in the population over 65 years of age is causing a major impact on health systems. This study aims to explore the needs and preferences of the multimorbid patient and carers to improve the palliative care received. The perspective of professionals who work with this profile of patients was also taken into account. A qualitative study was conducted using semi-structured interviews with open-ended questions. Separate topic guides were developed for patients, careers and health professionals. We included 12 patients, 11 caregivers and 16 health professionals in Spain. The results showed multiple unmet needs of patients and families/caregiv…

Ancient bridges of Sicily: punctual signs of a past that disappears

2018

Sono indelebili i segni lasciati dall’uomo sul territorio, testimonianze che il tempo conserva e la storia ci consegna e il cui insieme costituisce una trama fittissima che si sovrappone alla struttura fisica dell’ambiente, integrandolo e modificandolo. Grandi opere, monumenti universalmente riconosciuti come capolavori della mente e delle mani dell’uomo, ma anche opere minori, manufatti d’uso comune, beni isolati che costituiscono gli elementi puntuali di una più vasta e complessa organizzazione di fenomeni insediativi, le tessere di un mosaico ricco di sfumature e riflessi, frutto di un lungo processo di stratificazione storica. Alla categoria dei beni isolati appartengono le torri, i cas…
