Computational Fluid Dynamics (CFD) and Finite Element Analysis (FEM) of a Customized Stent-Graft for Endovascular (EVAR) Treatment of Abdominal Aorti…
2023
Background: The treatment of abdominal aortic aneurysm (AAA) is today commonly treated by inserting a stent-graft by the endovascular route, without resorting to open surgery. However, some clinical cases do not allow this less invasive approach, meaning that the stent-graft cannot be inserted and open surgery is used. Methods: In the study, we propose a fluid–structure interaction (FSI) analysis of an aneurysmatic aorta that could not be treated with Endovascular Aneurysm Repair (EVAR). The vessel is reconstructed through segmentation from CT scans and subsequently modeled on CAD software to create the surface and thickness of the vessel itself. Subsequently, we proceeded to carry out Comp…
“Dealing With Patients’ Mobility Issues: An Inter-Institutional Perspective To Analyze The Phenomenon And To Support Sustainable Policy Making In Sic…
2014
Nowadays many Italian policy makers, both at a national and regional level, are devoting a growing attention to the phenomenon of patients’ movements seeking public healthcare treatments out of the territorial jurisdiction. This paper presents the main features of a research project being carried out to analyze the mobility flows of Sicilian patients towards other Italian Regions in order to support the design of sustainable related policies. Such study adopts an inter-institutional perspective as the design of sustainable mobility-related policies requires a coordination effort of the Regional Healthcare Department, the Local Health Authorities and the Healthcare providers. The main outcom…
Constructing a pedagogical practice across disciplines in pre-service teacher education
2019
In this paper we report a qualitative case study of a teaching intervention in which a pre-service subject teacher pair planned and conducted a course integrating Finnish language and ethics in a multilingual setting. Audio-recorded planning sessions and interviews including learning diaries were analysed using qualitative content analysis to identify the dynamics of collaborative cross-curricular pedagogical practice development and pedagogical language knowledge. The analysis revealed tensions in crossing the boundary between language and content knowledge. The study suggests that when creating cross-curricular practices, student teachers benefit from longer-term processes and theory-base…
An Ecological Conceptualization of Extreme Sports
2018
Currently, there are various definitions for extreme sports and researchers in the field have been unable to advance a consensus on what exactly constitutes an ‘extreme’ sport. Traditional theory-led explanations, such as edgeworks, sensation seeking and psychoanalysis, have led to inadequate conceptions. These frameworks have failed to capture the depth and nuances of experiences of individuals who refute the notions of risk-taking, adrenaline- and thrill-seeking or death-defiance. Instead, participants are reported to describe experiences as positive, deeply meaningful and life-enhancing. The constant evolution of emerging participation styles and philosophies, expressed within and across…
Diversifying crop rotations with temporary grasslands: potentials for weed management and farmland biodiversity
2010
Fruchtfolgen können dazu dienen, die kontinuierliche Selektion von Unkrautarten zu verhindern, die an eine bestimmte Kultur angepasst sind. Dies könnte dem Unkrautmanagement, der Einsparung von Herbiziden, und der Biodiversität dienen. Heutige, sehr einfache Furchtfolgen könnten durch mehrjährige Futterkulturen diversifiziert werden. Die Einflüsse solcher mehrjähriger Kulturen auf Unkräuter wurden in vier Ansätzen untersucht : 1) Vegetationsaufnahmen auf 632 Feldern in Westfrankreich zeigten, dass die Unkrautzusammensetzung zwischen mehrjährigen Futterkulturen und einjährigen Kulturen stark variiert. Der Vergleich von Feldern vor, während und nach mehrjährigen Futterkulturen legte nahe, das…
System Dynamics Models To Support Health Care Companies In Managing Clinical Risk
2011
Clinical risk management has gained an increasing relevance because of the higher monetary and no monetary effects of clinical errors on health care companies' performance. For this reason, different risk management techniques from the industrial sector have been adopted by managers of health care companies in order to reduce the occurrences of errors and their relative impacts. However, these methods, based on a linear and static perspective, do not properly support the health care companies' management in the identification and assessment of policies aimed at improving the clinical risk profile without reducing financial performances. Therefore, it is necessary to adopt a systemic and mul…

METROPOLITAN PERSPECTIVES AND NEW LIFECYCLES FOR THE OUTSKIRTS
2017
La nuova prospettiva offerta dall'istituzione delle nuove città metropolitane richiede il superamento di una metropolizzazione gerarchica concentrica e l'adesione a processi di post-metropolizzazione più maturi, in cui un sistema insediativo policentrico riattivi il metabolismo urbano e rigeneri i cicli vitali delle città (energia, acqua, rifiuti), delle infrastrutture e dei paesaggi. L'obiettivo dell'incremento della qualità dell'abitare metropolitano trova nelle periferie un campo privilegiato di sperimentazione in cui agire al contempo attraverso azioni di macro-livello tese al contenimento del pendolarismo, al governo della rendita (che gioca un ruolo determinante nel processo di urbani…
