Liberty winter gardens in Palermo: contamination from solar design
2020
At the end of the 19th century, the city of Palermo boasted a tradition of steel elements that could include the most beautiful railings and light steel structures of the time. The paper shows how the technological, formal and spatial aspects of the metallic construction was derived by the application of Central Europe areas examples to the local reality, providing notions on designs, experimentations and originalities. Canopies, verandas, winter gardens and orangeries are architectural elements in iron and glass that represent an added value for the building, they improve the life quality of the people who live there. In particular, in the Liberty architecture these elements took shape thr…
Formaldehyde: Catalytic Oxidation as a Promising Soft Way of Elimination
2013
International audience; Compared to other molecules such as benzene, toluene, xylene, and chlorinated compounds, the catalytic oxidation of formaldehyde has been studied rarely. However, standards for the emission level of this pollutant will become more restrictive because of its extreme toxicity even at very low concentrations in air. As a consequence, the development of a highly efficient process for its selective elimination is needed. Complete catalytic oxidation of formaldehyde into CO2 and H2O using noble-metal-based catalysts is a promising method to convert this pollutant at room temperature, making this process energetically attractive from an industrial point of view. However, th…
Geophysical and geotechnical investigations to support the restoration project of the Roman ‘Villa del Casale’, Piazza Armerina, Sicily, Italy
2011
A multidisciplinary geophysical and geotechnical study, including some non-invasive geophysical applications, was carried out during the restoration of the ‘Villa del Casale’, a Roman villa discovered near Piazza Armerina (Sicily, Italy) in 1929, famous for its Roman floor mosaics. The project aims were to characterize the geology of the subsoil and provide information for solving the main building structural problems including the subsidence of some parts of the floor and the detachment of the tesserae (i.e., the tiles) of the mosaics. Another goal was the detailed study of the underground structures of the Corridor of the Great Hunt, a part of the villa strongly affected by subsidence and…
A multidisciplinary approach to the study of cultural heritage environments: Experience at the Palatina Library in Parma
2015
The aim of this paper is to describe a multidisciplinary approach including biological and particle monitoring, and microclimate analysis associated with the application of the Computational Fluid Dynamic (CFD). This approach was applied at the Palatina historical library in Parma. Monitoring was performed both in July and in December, in the absence of visitors and operators. Air microbial monitoring was performed with active and passive methods. Airborne particles with a diameter of ≥0.3, ≥0.5, ≥1 and ≥5 μm/m3, were counted by a laser particle counter. The surface contamination of shelves and manuscripts was assessed with nitrocellulose membranes. A spore trap sampler was used to identify…
Cinema audiences reproducibly vary the chemical composition of air during films, by broadcasting scene specific emissions on breath
2016
AbstractHuman beings continuously emit chemicals into the air by breath and through the skin. In order to determine whether these emissions vary predictably in response to audiovisual stimuli, we have continuously monitored carbon dioxide and over one hundred volatile organic compounds in a cinema. It was found that many airborne chemicals in cinema air varied distinctively and reproducibly with time for a particular film, even in different screenings to different audiences. Application of scene labels and advanced data mining methods revealed that specific film events, namely “suspense” or “comedy” caused audiences to change their emission of specific chemicals. These event-type synchronou…
IL COMFORT INDOOR, STRUMENTI LEGISLATIVI: PANORAMA LEGISLATIVO INTERNAZIONALE E NAZIONALE
2022
Già da qualche decennio si parla di IEQ (Indoor Environmental Quality) con particolare attenzione sulla salubrità dell’ambiente costruito e alla sua possibile influenza sulla sostenibilità ambientale. Tale interesse si è riversato per lo più sulla qualità dei prodotti e delle tecnologie dell’edilizia, incentrando la questione sulle prestazioni di essi e sugli effetti ambientali che essi generano. Con gli obiettivi previsti dall’Agenda 2030 si supera l’idea che la sostenibilità sia una prerogativa ambientale e si afferma una visione olistica mirata alla salute umana (obiettivo 3), emergendo la necessità di un passaggio da un approccio “Green” al costruito verso un approccio “Human Centred” c…
Indoor Comfort in School Buildings: The Case Study of Palermo
2014
Buildings primary energy consumption in developed countries accounts for about 40% of whole uses. Therefore, the European Union has released many regulations, concerning energy saving issues; particularly, it has enacted Directive 2002/91/EC regarding the energy performance of buildings, and its Recast Directive 2010/31/EU, that promotes the Nearly Zero Energy Building targets, introducing more strict parameters in this aim. Furthermore, the latter Directive asks Member States to include within their national plans measures aimed at supporting public authorities to become early adopters of building energy efficiency improvements. In the same time, Public Authorities should implement effecti…
Universally Designed Beacon-Assisted Indoor Navigation for Emergency Evacuations
2019
International audience; The United Nations (UN) Convention on the Rights of Persons with Disabilities (CRPD) obligates national governments to ensure the protection and safety of persons with disabilities in emergency situations. This article examines the application and accessibility of state-of-the-art ICT solutions in emergency situations. Research has indeed shown that the design and implementation of evacuation procedures in emergency situations play a critical role in ensuring personal safety and protection. While research has examined the experiences of persons including persons with disabilities in emergency situations, research has yet to examine fully the role that cutting-edge in…
Mean power during 20 sec all-out test to predict 2000-m rowing ergometer performance in national level young rowers
2014
Aim. The aim of this study was to assess the relationship between mean power during 20-s all-out rowing ergometer test and 2000-m rowing ergometer performance, in 20 young male rowers (mean age 15.2 ± 1.3 years). Methods. Mean power during 20-s all-out test (W20), maximal oxygen uptake during incremental test (VO2max), and anthropometric values, were measured and correlated with the time to perform a 2000-m trial (t2000). Results. W20 showed the highest correlation with t2000 (r = -0.947, P < 0.0001). Stepwise multiple linear regression analysis showed that W20, VO2max, and fat-free mass, were the variables most correlated with t2000, accounting for 95.1% of the variance, and that 89.7% …
The association of cooking fuels with depression and anxiety symptoms among adults aged ≥65 years from low- and middle-income countries
2022
Background: We aimed to investigate associations of unclean cooking fuels with depression and anxiety symptoms in a large sample of adults aged ≥65 years from six low- and middle-income countries (LMICs). Methods: Cross-sectional, community-based, nationally representative data from the WHO Study on global AGEing and adult health (SAGE) were analyzed. Unclean cooking fuel referred to kerosene/paraffin, coal/charcoal, wood, agriculture/crop, animal dung, and shrubs/grass. Depression referred to DSM-IV depression based on past 12-month symptoms or receiving depression treatment in the last 12 months. Anxiety symptoms referred to severe/extreme problems with worry or anxiety in the past 30 day…
