Towards a local approach to fatigue, for the calculation of structures, applied to continuous fibre reinforced composite materials and structures

2018

The original concept of mechanical fatigue was linked to the failure of structures and was treated at first within the framework of Fracture Mechanics. Models developed to explain this phenomenon must therefore be able to be applied to structures: changing the structure means changes to the model and its identification. It is therefore judicious to develop models capable of treating both the damage processes and also able to be used within a local framework: to this end a method based on Damage Mechanics seems appropriate. This approach has long been employed and requires only the identification of damage processes at the level of the RVE (Representative Volume Element) to be used for any s…

Newly discovered orichalcum ingots from Mediterranean sea: Further investigation

2021

Abstract In February 2016, 47 ingots were found in the seabed of Contrada Bulala (Gela, CL, Italy) near the site where 40 ingots had previously been recovered. The ingots composition was determined to be a Cu - Zn alloy, dated by the archaeologist to the VI century B.C. This specific alloy was then known as Orichalcum. From an archaeological point of view, the first question raised about the new discovery was whether the ingots of the first and the second excavations belonged to the same shipwreck. Following the previous study, an elemental analysis was performed on the ingots from the second finding by using ICP-OS and ICP-MS techniques. The chemometric treatment of the analytical results …

A bottom-up harmonized energy-environmental models for europe (BOHEEME): A case study on the thermal insulation of the EU-28 building stock

2021

Abstract The paper presents a methodological approach, called “BOttom-up Harmonized Energy-Environmental Models for Europe” (BOHEEME), that combines bottom-up modeling, energy dynamic simulation, and life cycle assessment for evaluating and comparing the energy and environmental effects of different renovation strategies of the residential EU building stocks, from micro to the macro level. The study defines 672 building models representative of the residential EU-28 building stocks built before 2010, called archetypes, and the improvement of their envelope, applying different insulation materials from a traditional one to bio-based materials and studying their environmental effects via LCA.…

The Averinga’s Edicola and the Cult of Water in Palermo. From Knowledge to Valorisation

2018

Si descrive un approccio multidisciplinare allo studio di un singolare monumento storico, l’Edicola dell’Averinga, che versa attualmente in gravi condizioni di degrado; questa costruzione fu realizzata nel 1587 dal Senato Palermitano a protezione delle acque della sorgente Ayn Rutah (nome arabo di Averinga) che sgorgavano proprio al suo interno e che da qui venivano raccolte e incanalate verso i fertili giardini, le abitazioni che si trovavano in prossimità delle mura cittadine e alcune delle più importanti fontane della città storica. La più antica descrizione a noi pervenuta della zona in cui è sita l'Edicola, la cosiddetta depressione Danisinni, appartiene al geografo iracheno Al-Qaim Mu…

The Waterfront Theorem: an integrated and creative planning approach

2016

Waterfronts are sensitive interfaces between land and sea, creative interfaces between urban and environmental components, social interfaces between nodes and networks. They not only coincide with the areas of infrastructure that are gathering on the coast, not only with the shoreline or the environmental components of the coastal territories. They are hired by the project as complex interaction of crossing flows, stratified identity of urban communities: fundamental element of the environmental system, synthesis of landscape, space and community, a place of solidification of the identity of the social, cultural and economic community (Carta, 2009). The management of urban interface of wate…

Cap Rate as the Interpretative Variable of the Urban Real Estate Capital Asset: A Comparison of Different Sub‐Market Definitions in Palermo, Italy

2017

Real estate capital is in constant competition with other capital assets due to its different and complementary economic functions such as direct use, productive investment, and speculative investment. These features and the resulting opportunities cannot be easily deduced from direct observation of the real estate markets, so some further insights need to be carried out in order to highlight the relationship between prices, rents and performances. This study aims at providing a multifaceted perspective of a specific urban real estate market to overcome the difficulties arising from opacities and informative asymmetries that hinder the decision of investors, by facilitating the comparison o…

Foreign language teaching within special needs education: learning from Europe-wide experience

2005

In this article, Anne Stevens and David Marsh focus on the main aspects of the argument and discussion raised in the recently published European Commission (2005) report on the teaching and learning of languages in the context of special educational needs. They explore the avenues of possible action that should follow if the issues raised in the report are to be effectively addressed.

Collecting and Using Students’ Digital Well-Being Data in Multidisciplinary Teaching

2018

This article examines how students (N=198; aged 13 to 17) experienced the new methods for sensor-based learning in multidisciplinary teaching in lower and upper secondary education that combine the use of new sensor technology and learning from self-produced well-being data. The aim was to explore how students perceived new methods from the point of view of their learning and did the teaching methods provide new information that could promote their own well-being. We also aimed to find out how to collect digital well-being data from a large number of students and how the collected big data set can be utilized to predict school success from the students’ well-being data by using machine lear…

Vector-borne and zoonotic infections and their relationships with regional and socioeconomic statuses: An ID-IRI survey in 24 countries of Europe, Af…

2021

Background: In this cross-sectional, international study, we aimed to analyze vector-borne and zoonotic infections (VBZI), which are significant global threats. Method: VBZIs’ data between May 20–28, 2018 was collected. The 24 Participatingcountries were classified as lower-middle, upper-middle, and high-income. Results: 382 patients were included. 175(45.8%) were hospitalized, most commonly in Croatia, Egypt, and Romania(P = 0.001). There was a significant difference between distributions of VBZIs according to geographical regions(P < 0.001). Amebiasis, Ancylostomiasis, Blastocystosis, Cryptosporidiosis, Giardiasis, Toxoplasmosis were significantly more common in the Middle-East while B…
