Preliminary Evaluation of Plasmix Compound from Plastics Packaging Waste for Reuse in Bituminous Pavements
2021
Finding an appropriate technical solution for reusing waste plastics is crucial for creating a circular plastic economy. Although mechanical recycling is the best option for recycling post-consumer plastics, some heterogeneous mixed plastics cannot be recycled to produce secondary material due to their very low properties. In this case, alternative routes should be considered in order to limit their disposal as much as possible. Therefore, in order to solve the environmental problems in the landfills of plastic waste recycling, and to improve the mechanical performance of bitumen for road pavement, the reuse of these post-consumer plastic wastes are preliminarily evaluated for the modificat…
MUV: A Game to Encourage Sustainable Mobility Habits
2019
This working paper investigates the question of changing people mobility towards more sustainable habits involving them in an engaging gameplay. The work is performed within MUV H2020 research and innovation action. The game design, definition and features have been co-created through the involvement of different citizens and stakeholders in six European neighbourhoods. The paper discusses the game design as resulting from co-creation and co-design experiences with each neighbourhood communities involved in initial phases. The paper argues that the local co-design activities have influenced the game definition, together with the community engagement approach. The MUV gameplay approach resul…
The role of water in sustainable architecture
2011
Today’s propulsive push towards the 3th millennium, driven forward by technological innovation, needs to grapple with an economic and environmental global crisis. Generally speaking water is synonymous with life; in bio-climatic architecture it is synonymous with thermal comfort, since water is able to regulate the micro-climate of various interiors, help solar radiation and brighten up internal spaces. There is more, however. In certain cases, water becomes an actual building element: thanks to the considerable power of its thermal mass, it can be used in passive solar systems (with the “drum wall” in place of stone, brick or concrete walls), through the employment of the “trombe” wall, or…
Gingivitis
2014
Gingival inflammation is caused by bacterial plaque (dental biofilm) that accumulates daily on the teeth. Results in redness, slight swelling, or "puffiness" of the gums and bleeding on tooth brushing. Treatment involves thorough professional tooth cleaning and effective daily removal of dental plaque by tooth brushing and cleaning between the teeth. Necrotizing ulcerative gingivitis (NUG) is a more serious condition that is mainly found in developing countries associated with people with severe malnutrition or HIV/AIDS with low CD4 T-cell counts.
Riconfigurare i territori metroplitani. Forme di urbanizzazione e fenomeni di pressione insediativa sui sistemi di interesse naturale in Sicilia
2018
The consumption of the soil due to urbanization it is a phenomena already for many years under observations, but of which only the scientific environment has noticed the elevated environmental impact progress. From a disciplinary point of view, is possible to identify a line of research focusing on the analysis and identification of new morphologies of urbanization and on the interaction among different settlement patterns coexisting in a specific context. This reading complements with the scientific production about the forms of settlement pressure on environmental systems, producing change and deterioration on natural ecosystems and loss of biodiversity. A necessary reference for this lin…
On the friction/tangential restitution problem: Independent friction-restitution modeling of sphere rebound with arbitrary spin
2023
Most descriptions of collision events introduce coefficients of friction and tangential restitution which vary significantly with the impact angle, in contrast with the independence of the normal coefficient of restitution with this parameter. A redefinition of the coefficients of friction and tangential restitution based on the idea that friction and restitution effects can be treated as being mutually independent, provides a satisfactory description of experimental data using a ‘constant’ restitution coefficient independent on the impact angle. This independent friction-restitution modeling is developed here for the rebound of a homogeneous sphere having an arbitrary spin on a rough massi…
"Writing to Learn or Learning to Write". A Critical Review of "English as a Foreign Language" (EFL) Teaching Practices in Writing in Saudi Universiti…
2020
Developing proficiency in English writing has always been a challenge for L2 learners in general and Saudi learners in particular. Despite the widespread presence of English departments as a result of the sharp rise of Saudi universities in the previous decade, the numbers of outcomes or achievements in terms of skills are very discouraging. This paper aims to study this issue closely by investigating the most crucial elements that are likely to explain this weakness by reviewing the related empirical and theoretical studies in the Saudi context. This paper also aims to present to researchers a quick reference as to how English writing skills have evolved in Saudi Arabia in the recent past,…
Specificità costruttive nei teatri storici. Il “Garibaldi” di Palermo tra incolti stravolgimenti e fortunate permanenze

Hacia el actor profesional en el teatro peninsular del Renacimiento
2015
Los albores del Renacimiento peninsular ven nacer unas prácticas escénicas dependientes del Poder, creadas y desarrolladas en la Corte por los llamados padres del teatro castellano y portugués: Juan del Encina, Lucas Fernández y Gil Vicente. No siempre se ha prestado atención a su producción desde el punto de vista de la puesta en escena y aún menos a los actores que la ejecutaron. Esta Tesis Doctoral pretende abrir una senda hacia el estudio de la actuación de estos primeros representantes luso-castellanos, durante la etapa anterior a la profesionalización del oficio. La investigación se inicia mediante la elaboración de un marco teórico que recupera los materiales que marcaron el desarrol…
Prometeo genetista. Profitti delle tecniche e metafore della scienza
2016
Il saggio di Claude Calame affronta una tematica di grande rilievo scientifico, ossia il confronto tra il valore epistemologico e sociale dell'uso delle arti tecniche nell'antica Grecia e il valore epistemologico del linguaggio della scienza moderna in particolare applicato all'ambito della genetica e delle moderne biotecnologie e scienze di laboratorio. Lo spunto del confronto è offerto dall'analisi storico-culturale e antropologica del mito di Prometeo, come è stato diversamente declinato dai vari autori dell'antichità classica, a partire da Esiodo sino a Platone, passando per l'autore del dramma "Prometeo incatenato". In una prospettiva di indagine antropopoietica, le arti tecniche perme…
