I Cannot Place You: Dementia and the Pandemic Experience in The Visiting Hour by Frank McGuinness

2021

This paper presents a new play by Frank McGuinness, a play which was streamed to audiences in April 2021 and published a few weeks later. Set in contemporary Ireland, it focuses on two themes which seem to preoccupy its author: dementia, to which he devoted another play, Hanging Gardens and the consequences of living in a time of Pandemic. In particular, I argue, McGuinness indirectly seems to address an important question: how can literature and theatre offer an opportunity for reflecting about what is happening around us? Can literature help us to better understand and face the world? The play foregrounds the restorative power of emotional authenticity as we see a father and his daughter …

Interferometric microscopy study of the surface roughness of Portland cement under the action of different irrigants

2013

Objectives: Some investigations suggested common Portland cement (PC) as a substitute material for MTA for endodontic use; both MTA and PC have a similar composition. The aim of this study was to determine the surface roughness of common PC before and after the exposition to different endodontic irrigating solutions: 10% and 20% citric acid, 17% ethylenediaminetetraacetic (EDTA) and 5% sodium hypochlorite. Study Design: Fifty PC samples in the form of cubes were prepared. PC was mixed with distilled water (powder/liquid ratio 3:1 by weight). The samples were immersed for one minute in 10% and 20% citric acid, 17% EDTA and 5% sodium hypochlorite. After gold coating, PC samples were examined …

Charged Bis-Cyclometalated Iridium(III) Complexes with Carbene-Based Ancillary Ligands

2013

Charged cydometalated (CN) iridium(III) complexes with carbene-based ancillary ligands are a promising family of deep-blue phosphorescent compounds. Their emission properties are controlled primarily by the main CN ligands, in contrast to the classical design of charged complexes where NN ancillary ligands with low-energy pi* orbitals, such as 2,2'-bipyridine, are generally used for this purpose. Herein we report two series of charged iridium complexes with various carbene-based ancillary ligands. In the first series the CAN ligand is 2-phenylpyridine, whereas in the second one it is 2-(2,4-difluorophenyl)-pyridine. One biscarbene (:CC:) and four different pyridine carbene (NC:) chelators a…

Exergy analysis of electrodialysis for water desalination: Influence of irreversibility sources

2022

The increasing freshwater demand is pushing the development and adoption of desalination technologies. In this framework, electrodialysis has a consolidated role in brackish water desalination, but to make it competitive with other technologies for the desalination of more concentrated solutions (e.g., seawater), the specific energy consumption should be reduced. Exergy analysis provides a useful tool for determining the contribution of each thermodynamic inefficiencies on the process efficiency and the specific energy consumption. In this regard, this paper presents an exergy analysis of the electrodialysis process. A 1-D model is used for evaluating the performance of industrial-scale sys…

White-light phosphorescence emission from a single molecule: application to OLED.

2009

A simple mononuclear cyclometallated iridium(III) complex exhibits white photo- and electro- luminescence in the wavelength range from 440 to 800 nm, which originates from a single emitting excited state of mixed character.

"A Detenção administrativa dos Estrangeiros irregulares na Itália e na União Europeia e o Direito humano fundamental à Liberdade privada e à ampla De…

2014

Na Itália, como em outros Estados da União Europeia, vem ocorrendo recentemente nos últimos anos o fenômeno da "detenção administrativa" dos cidadãos estrangeiros irregulares, bem como dos requerentes de asilo, a maioria proveniente da África, do Oriente Médio e da Península Balcânica. Esses imigrantes, pelo simples fato de terem ingressado irregularmente no território europeu, apesar da imigração ilegal não constituir delito, são privados da liberdade pessoal ou de circulação e permanência, sendo detidos pelas autoridades de segurança pública, às vezes sem a validação da autoridade jurisdicional, durante um período de tempo também muito prolongado, em determinados locais, formais ou inform…

Indagini Scientifiche

2019

In questo contributo sono riportati i risultati della campagna diagnostica effettuata sul dipinto murale “Atelier“, opera giovanile di Antonio Sanfilippo (1923-1980), ritrovato sotto una scialbatura che, sebbene lo abbia nascosto, allo stesso tempo lo ha preservato.

Self-similar focusing with generalized devil's lenses

2011

[EN] We introduce the generalized devil's lenses (GDLs) as a new family of diffractive kinoform lenses whose structure is based on the generalized Cantor set. The focusing properties of different members of this family are analyzed. It is shown that under plane wave illumination the GDLs give a single main focus surrounded by many subsidiary foci. It is shown that the total number of subsidiary foci is higher than the number of foci corresponding to conventional devil's lenses; however, the self-similar behavior of the axial irradiance is preserved to some extent.
