Tunnel fire active protection: improving ventilation system
2019
Abstract The main aim of this work is to evaluate how the use of an active protection method, consisting in an improved forced longitudinal ventilation system, can determine a positive impact on heat extraction and people evacuation time in a tunnel fire scenario, by considering a case study which simulations are based on a real gallery.
Making Bishops in the Malta of the Knights, 1530-1798
2015
During the early modern age the appointment of Maltese bishops involved conflicts in the management of ecclesiastical patronage, jurisdictional issues and international diplomacy. The procedure for appointment, established by Charles v in 1530 when he granted Malta to the Order of St John, was the result of a compromise: safeguarding rights of royal patronage without undermining the independence of an international military order. It is important, however, to underline the reforming activity conducted by bishops appointed in such political ways, especially through the application of some institutions provided by the Council of Trent, such as diocesan synods.
Critical Studies on Men in Ten European Countries: (1) The State of Academic Research
2002
This article is on the work of the European Research Network on Men in Europe project, “The Social Problem and Societal Problematization of Men and Masculinities” (2000-2003), funded by the European Commission. The Network comprises women and men researchers with a range of disciplinary backgrounds from Estonia, Finland, Germany, Ireland, Italy, Latvia, Norway, Poland, the Russian Federation, and the United Kingdom. The Network's initial focus is on men's relations to home and work, social exclusion, violence, and health. Some of the findings on the Network's fourth phase of work, namely the review of newspaper and media representations of men's practices in the ten countries, are presented…
Analysis of a full-scale integral test in PERSEO facility by using TRACE code
2017
Over the last decades a lot of experimental researches have been done to increase the reliability of passive decay heat removal systems implementing in-pool immersed heat exchanger. In this framework, a domestic research program on innovative safety systems was carried out leading the design and the development of the PERSEO facility at the SIET laboratories. The configuration of the system consists of an heat exchanger contained in a small pool which is connected both at the bottom and at the top to a large water reservoir pool. Within the frame of a national research program funded by the Italian minister of economic development, the DEIM department of the University of Palermo in coopera…
Inoculum of Indigenous Microalgae/Activated Sludge for Optimal Treatment of Municipal Wastewaters and Biochemical Composition of Residual Biomass for…
2022
In this work, municipal wastewater was treated with microalgal/activated sludge consortia. We aimed at obtaining a positive interaction between the microalgae and the heterotrophic bacteria and identifying the best combination for bioremediation purposes. A strain of Chlorella sp CW2 employed in this work was isolated from AS and molecularly characterised in this work for the first time. This strain and another previously isolated strain (Chlorella sp Pozzillo) were inoculated alone and in combination with AS in different ratios in wastewaters. Microalgae/activated sludge growth curves were obtained by using a UV–vis spectrophotometer and a fluorimeter to distinguish the contribution of the…
Efficiency of QuEChERS approach for determining 52 pesticide residues in honey and honey bees
2016
A comparison between QuEChERS and other pesticide extraction procedures for honey and honey bee matrices is discussed. Honey bee matrix was extracted by solvent based procedure whereas solid phase extraction was the protocol for the honey matrix. The citrate buffered QuEChERS method was used for both matrices. The methods were evaluated regarding cost (equipment and reagents), time, accuracy, precision, sensitivity and versatility. The results proved that the QuEChERS protocol was the most efficient method for the extraction of the selected pesticides in both matrices. QuEChERS is the most economical and less time-consuming procedure.SPE and solvent-based extraction procedures show equivale…
COVID-Guide: An app for Covid-19 triage and self-assessment
2021
Introduction. The unprecedented covid-19 pandemic has shown the weaknesses of health systems and opened new spaces for e-health and telemedicine. Recent literature states that chatbots, if implemented effectively, could be useful tools for quickly sharing information, promoting healthy behaviors, and helping reduce the psychological burden of isolation. The aim of this project is to develop and test a secure and reliable computerized decision support system (CDSS) in web-app and evaluate its use, usability and its outputs in a pre-specified way. Methods. A multidisciplinary team was recruited to plan and design, based on the SMASS medical CDSS, the scenarios of the COVID-Guide web-app, a se…
Evolution of risk management in health care system: Survey on the adverse events occurred in Palermo University Hospital Policlinico “Paolo Giaccone”
2019
Introduction. We aimed at carrying out a quantitative and qualitative analysis of claims for adverse events addressed to Palermo University Hospital Policlinico “Paolo Giaccone” in order to promote evidence-based interventions and increase patient safety. Methods. A retrospective study of 296 claims collected between 1st of January, 2014 and 31st of December, 2017 by Quality and Clinical Risk Management staff unit was performed along with descriptive analysis of any associated determinant factors. Results. The most frequent causes of claims consisted of wrong surgical procedures (33.8%), mistaken diagnoses (18.6%), falls (17.6%), infections (6.4%), postoperative complications (5.4%) and wro…
Green tea extract assisted low-temperature pasteurization to inactivate enteric viruses in juices.
2020
The current popularity of minimally processed foods is an opportunity for natural antimicrobial agents to be combined with mild heat treatments to act synergistically in reducing viral foodborne pathogens. Viral inactivation by heat-treatments (at 25, 40, 50 and 63 °C for 30 min) combined with aged green tea extract (aged-GTE) was initially evaluated in phosphate buffered saline (PBS) against murine norovirus (MNV-1) and hepatitis A virus (HAV) by cell culture, and against human norovirus by in situ capture RT-qPCR. The combination of aged-GTE and heat treatment at 50 °C for 30 min exerted strong antiviral activity, reducing by more than 5 log MNV-1 infectivity in PBS. Heating at 40 °C for …
Force/Torque-Sensorless Joint Stiffness Estimation in Articulated Soft Robots
2022
Currently, the access to the knowledge of stiffness values is typically constrained to a-priori identified models or datasheet information, which either do not usually take into ac- count the full range of possible stiffness values or need extensive experiments. This work tackles the challenge of stiffness estimation in articulated soft manipulators, and it proposes an innovative solution adding value to the previous research by removing the necessity for force/torque sensors and generalizing to multi-degree- of-freedom robots. Built upon the theory of unknown input-state observers and recursive least-square algorithms, the solution is independent of the actuator model parameters and its in…
