Old towns in “smart cities” between conservation and metamorphosis. Pending European Union guidelines
2014
In reflecting upon the role of environmental capital as represented by old towns in smart cities, the author reveals the consequences of re-plastering the facade of ancient buildings while emphasizing the resulting risk of globalization of historic districts. This is followed by a critical consideration concerning the active protection of old towns and their cultural typicality and geographical context, prerequisites for the development of specific guide-lines for the European Union. Explanation is also provided about how the restoration dynamics of the old towns are irreversibly changing the urban landscape in European cities. Strict regulations regarding the preservation of European old t…
Experimental investigation of holes interaction effect on the sound absorption coefficient of micro-perforated panels under high and medium sound lev…
2011
Abstract This paper experimentally investigates the holes interaction effect on the sound absorption coefficient of micro-perforated panels under high and medium sound levels. The theoretical formulations are based on a semi-empirical approach and the use of Fok’s function to model the acoustic surface impedance. For the high sound level regime, an empirical power law involving three coefficients is adapted. It is shown theoretically and experimentally that these coefficients can lead to optimized absorption performance and particularly, a formula relating the critical Reynolds number (Reynolds number value after which the absorption coefficient decreases with the increase of sound level) a…
Towards a Wellbeing-driven System Design for Intergenerational Collaborative Innovation: A Literature Review
2020
Researchers have previously utilized the advantages of a design driven by well-being and intergenerational collaboration (IGC) for successful innovation. Unfortunately, scant information exists regarding barrier dimensions and correlated design solutions in the information systems (IS) domain, which can serve as a starting point for a design oriented toward well-being in an IGC system. Therefore, in this study, we applied the positive computing approach to guide our analysis in a systematic literature review and developed a framework oriented toward well-being for a system with a multi-generational team. Our study contributes to the IS community by providing five dimensions of barriers to I…
La colaboración científica: principales líneas de investigación y retos de futuro
2014
The construction of knowledge is a collaborative process that has seen a dramatic growth over recent decades, since almost all research activities now involve increasing numbers of researchers, institutions, disciplines and countries. The present study provides a bibliographic review of the literature on research collaboration and identifies pioneering work on the topic, the types of studies undertaken and the variables analyzed. Several approaches are discussed: the “classical” approach, based on bibliometric indicators, which has taken on a new dimension with Social Network Analysis; and quantitative and qualitative approaches, which attempt to investigate the motivations and dynamics of …
Borane reaction chemistry. Alkyne insertion reactions into boron-containing clusters. Products from the thermolysis of [6,9-(2-HC[triple bond]C-C5H4N…
2008
The stirring of [ortho-(HC[triple bond]C)-C(5)H(4)N] with [nido-B(10)H(14)] in benzene affords [6,9-{ortho-(HC[triple bond]C)-C(5)H(4)N}(2)-arachno-B(10)H(12)] 1 in 93% yield. In the solid state, 1 has an extended complex three-dimensional structure involving intramolecular dihydrogen bonding, which accounts for its low solubility. Thermolysis of 1 gives the known [1-(ortho-C(5)H(4)N)-1,2-closo-C(2)B(10)H(11)] 2 (13%), together with new [micro-5(N),6(C)-(NC(5)H(4)-ortho-CH(2))-nido-6-CB(9)H(10)] 3 (0.4%), [micro-7(C),8(N)-(NC(5)H(4)-ortho-CH(2))-nido-7-CB(10)H(11)] (0.4%) , 4 binuclear [endo-6'-(closo-1,2-C(2)B(10)H(10))-micro-(1(C),exo-6'(N))-(ortho-C(5)H(4)N)-micro-(exo-8'(C),exo-9'(N))-(…
eTwinning e Scuole Nuove: collaborazione e valorizzazione del patrimonio culturale
2022
All’inizio del Novecento, la diffusione in Europa di numerosi modelli di rinnovamento educativo in linea con il movimento delle Scuole Nuove e il conseguente approfondimento della documentazione prodotta in quegli anni, permettono di riflettere ancora oggi sull’argomento. Il presente contributo mira a verificare se la piattaforma eTwinning possa oggi essere considerata come una delle possibili vie per attuare quanto auspicato cento anni fa dal movimento delle Scuole Nuove: incoraggiare la collaborazione tra i membri della comunità scolastica al fine di comprendere il valore della diversità e del patrimonio culturale. At the beginning of the twentieth century, the spread of numerous educatio…
Teaching the restoration of monuments at Palermo: the state of the art
2008
Il contributo spiega le modalità dell'insegnamento del restauro nella facoltà di Architettura di Palermo, illustrandone i contenuti anche con la preparazione di tesi di laurea The Architecture Faculty of the University of Palermo, founded in 19 5, is the oldest in Sicily; a Faculty of Architecture based in Siracusa was added in the 1990s and is dependant on the University of Catania; while in 2005 teaching began at the University Kore based in Enna, which o ers a three-year degree course in the Science of Architecture as part of its department of Fine Arts Conservation. The faculty of architecture of the University of Palermo provides a ve-year architecture course (cl 4/S) as well as anothe…
Surgically verified variations in the A1 segment of the anterior cerebral artery
1991
✓ Two patients with rare variations of the A1 segment of the anterior cerebral artery are presented. One patient had a perforation of the optic tract by an abnormal course of the A1 segment, and the other harbored an aneurysm of the A1 segment running below the optic nerve. The authors present a summary of A1 segment variations described in the literature.
