Analisi di sicurezza nella procedura di protonterapia oculare applicata presso i Laboratori del Sud dell’INFN di Catania
2017
A partire dal 2002, l’Azienda Ospedaliera Universitaria “Policlinico Vittorio Emanuele” di Catania ha effettuato il trattamento di circa 350 pazienti affetti da neoplasie oculari mediante fasci di protoni prodotti con il ciclotrone disponibile presso i Laboratori nazionali del Sud (LNS). Tale impianto viene utilizzato per attività di ricerca nell’ambito della fisica sperimentale, per cui è stato necessario modificare le caratteristiche del fascio, rendendolo idoneo alle applicazioni cliniche. Il lavoro di ricerca ha riguardato lo svolgimento della analisi del rischio volto ad individuare possibili fallimenti nelle procedure adottate per il trattamento del paziente sottoposto a cicli di prot…
Combining Membrane and Zero Brine Technologies in Waste Acid Treatment for a Circular Economy in the Hot-Dip Galvanizing Industry: A Life Cycle Persp…
2023
AbstractAn innovative approach of combining membrane and zero brine technologies for a joint treatment of industrial liquid waste is investigated regarding its environmental impacts compared to the existing liquid waste treatment. The object of investigation is the generation of waste acid solution by a hot dip galvanizing plant in Sicily, Italy. The waste acid solution contains hydrochloric acid, iron and zinc, which makes it a hazardous waste according to EU classifications. Environmental impacts are studied for two scenarios in the Tecnozinco hot-dip galvanizing plant in Sicily, Italy: (i) the current process of pickling with linear disposal of waste acid and (ii) the pickling combined w…
Feasibility of Producing Electricity, Hydrogen, and Chlorine via Reverse Electrodialysis
2022
Reverse electrodialysis (RED) is a technology to generate electricity from two streams with different salinities. While RED systems have been conventionally used for electricity generation, recent works explored combining RED for production of valuable gases. This work investigates the feasibility of producing hydrogen and chlorine in addition to electricity in an RED stack and identifies potential levers for improvement. A simplified one-dimensional model is adopted to assess the technical and economic feasibility of the process. We notice a strong disparity in typical current densities of RED fed with seawater and river water and that in typical water (or chlor-alkali) electrolysis. This …
Seawater Desalination for Freshwater Production
2009
In the last decades more and more countries have experienced water scarcity problems, thus pointing at alternative non-conventional sources of fresh water. Seawater desalination has proven to be a reliable and economically sustainable water resource since the second half of the 20th Century. A number of well proven technologies already exist, with advantages and disadvantages making each of them more suitable in specific sites. Moreover, quite recently, coupling the use of renewable energy to the production of fresh water from seawater results in novel technologies, able to minimise the environmental impact that desalination processes can create due to their intense energy consumptions.
Ottimizzazione Multi-Obiettivo delle Prestazioni Energetiche e Ambientali di un Edificio Residenziale
2019
Il presente lavoro, svolto nell’ambito dell’Annex 72 dell’International Energy Agency, descrive un approccio metodologico volto all’identificazione di interventi ottimali di ristrutturazione da effettuare sull’involucro di un edificio residenziale, permettendo di minimizzare contemporaneamente quattro funzioni obiettivo: i consumi energetici in fase d’uso, i costi d’investimento e gli impatti energetici e ambientali di ciclo di vita. L’ottimizzazione, eseguita tramite un algoritmo multi-obiettivo, ha permesso di identificare gli spessori di materiale isolante e di materiali massivi da aggiungere sul tetto e sulle pareti perimetrali dell’involucro edilizio per minimizzare le quattro funzioni…
Energy and environmental impacts of home automation components
2014
Life Cycle Assessment is applied to estimate the life cycle energy and environmental impacts of five components used in the home automation systems: an electricity meter, an actuator with an integrated current sensor, a web server audio/video, an interface with infrared emitter, a multimedia touch screen. For each component, the impacts related to “one unit of product” (selected as functional unit) are assessed following a “from cradle to grave” approach, including the manufacturing, operation and end-of-life steps. The results showed that the operation step gives a contribution higher than 54% on primary energy consumption and variable from about 54% to about 99% on environmental impacts, …
Ecological Invitation to Engage with Public Displays
2018
Interactive public displays pose several research issues, which include display blindness and interaction blindness. In this paper, we shortly introduce our idea of a sound-based system to overcome the display blindness, and some experiments that we are carrying out in order to test its effectiveness.
A mobile application for assessment of air pollution exposure
2013
In this paper the architecture of a mobile air quality monitoring system is introduced. A mobile application will act as a personal assistant, monitoring and giving advices about gas pollutants daily exposure. Currently in development stage as part of a larger air quality monitoring system project, the application will enable users to monitor their daily exposure to gas pollutants by combining user location data and urban air quality information provided by the network of fixed monitoring stations of the city of Palermo.
ACCERTAMENTO E VERIFICHE DELL'HANDICAP
2013
Questo studio indaga il tema dell’accertamento e delle verifiche dell’handicap nel quadro delle novelle legislative che affidano all’Istituto Nazionale della Previdenza Sociale (Inps) la regia dell’intero sistema di accertamento. Uno spazio significativo è, inoltre, dedicato all’istituto dell’accertamento tecnico preven- tivo obbligatorio, importante strumento di deflazionamento del contenzioso previdenziale. This study explores the theme of assessment and verification of handicap in the contest of the legislative novels that make National Social Security Institute (Inps) run the entire system of assessment. A significant space is also dedicated to the institute of technical appraisal requi…
Lactate level and handgrip test in migraine and fibromyalgia after self-myofascial release treatment
2019
The Aim of the study was to determine the effect of self-myofascial release (SMFR) treatment on handgrip test score in patients with fibromyalgia and migraine, investigating also if the lactate levels influenced the result. Twenty-five subjects affected by migraine (age 49.7±12.5; height 164.9±6.62 cm; weight 68.6±16.9 kg) and ten subjects affected by fibromyalgia (age 43.7±21.2; height 158±5.65 cm; weight 70±28.9 kg) were enrolled in the study. The assessments included a handgrip test, in order to evaluate isometric strength of both hands and forearm muscles and the lactate levels evaluation. The treatment was performed in the three most painful trigger points indicated from subjects as to…
