Mokṣopāya-Ṭīkā of Bhāskarakaṇṭha. The Fragments of the Nirvāṇaprakaraṇa. Part I. Critical Edition
No full textThe volume contains the critical edition of the first half of the large extant fragment of the Nirvāṇaprakaraṇa - the sixth section of the Mokṣopāya, the last and by far the most substantial - with Bhāskarakaṇṭha's commentary Nirvāṇaṭikā. The Mokṣopāya, a huge philosophico-soteriological work probably composed by a Kashmiri author in the tenth century of our era, was the original version of what would become the Yogavāsiṣṭha, which enjoyed enormous popularity in India, in certain regions second only to the two great epic poems. Bhāskarakaṇṭha (17th century), the commentator, is one of the last great non-dualist Śaivite masters from Kashmir
The divine scribe: A new interpretation of the Gaṇeśa episode from the Mahābhārata
No full textThe Gaṇeśa episode from the Mahābhārata, widely regarded as a late addition, narrates the mythical circumstances that led to the first written record of the poem: Vyāsa asks Gaṇeśa to write down the whole epic at his dictation. In the past, the episode was claimed to represent an attempt to promote the figure of Gaṇeśa, a god on the rise. Nevertheless, this explanation fails to account for the connection between the god and the act of writing an original work. A closer examination of the episode is therefore needed, with a view to reaching a more satisfactory interpretation. Our assumption is that the passage should be read as a realistic staging of the questions raised by the re- lationship between author, symbolised by Vyāsa, and scribe, symbolised by Gaṇeśa. In this context, the figure of Gaṇeśa serves to emphasize the relevance of the technology of writing and its professionals
Historic Building Information Modeling: from historical database platform to fully suitable and multidisciplinary design instruments
No full textThe aim of the research intends to provide innovative solutions to the more and more hard challenge of organizing in a virtuous manner the information concerning the architecture patrimony: the realization of complex parametric models could guarantee a formal, architectural and relational coherence, inside a shared virtual system. The HBIM (Historical Building Information Modeling) represent virtual models for cultural assets, essential supports to archive, compare, manage and design heterogeneous data that constitute the building: its analysis give the possibility to interpret it in a sort of "asis" model, made by deductions coming from information derived by archivist, geometrical and topology data contained into the virtual model. The report will focus particularly on the case study of the V Pavillion made by Riccardo Morandi nearby the Torino Esposizioni exhibition building cluster: built using the prestressed technology on concrete lowered arcs, it passed very fast from being an iconic building of the excellent Italian engineering school of the postwar period, to a debatable and malfunctioning municipal garage. For this reason the virtual model could be helpful to collect on one side a fully shared information database capable to transfer all the historical path of the building, and on the other the efficient and multidisciplinary instruments supporting future design interventions on the next period
Residui di procimidone in oli di oliva biologici siciliani
No full textNegli ultimi anni è stata riscontrata la presenza di Procimidone in oli di oliva dichiarati di natura biologica. Il Procimidone, N-(3,5-dichlorophenyl)-1,2-dimethylcyclopropane-1,2-dicarboximide è un fungicida ad ampio spettro impiegato per il trattamento dei prodotti orticoli e viticoli, e il suo utilizzo non è consentito per il trattamento delle malattie dell’ulivo. Si è ipotizzato che il suo ritrovamento nell’olio potrebbe essere dovuto sia ad un uso improprio che ad un fenomeno di contaminazione da “deriva” nel caso in cui le piante di olivo siano localizzate vicino a colture che abbiano subito il trattamento.
In base a tali considerazioni sono stati analizzati oli extravergini ottenuti da olive delle campagne olearie 2005/2006 e 2006/07 provenienti da aziende agricole dichiarate biologiche di varie zone della provincia di Trapani. L’analisi quali-quantitativa è stata effettuata sugli estratti acetonitrilici mediante Analisi Gas-cromatografica con ausilio di rivelatore di massa (HRGC-MS). Tutti i campioni all’infuori di due, hanno dato all’analisi positività per il Procimidone. Le concentrazioni variano da 0,015 a 0,113 ppm, con un valore medio di 0,040 ppm.
In ogni caso sia per i campioni di olio extravergine ottenuti da olive della campagna olearia 2005/2006 che per quelli ottenuti da olive dalla campagna olearia 2006/2007 si parla di valori sempre prossimi al minimo valore quantificabile (0,010 mg/K), pertanto si ipotizza che la contaminazione sia dovuta a fenomeni di deriva e non a usi diretti del principio attivo sull’olivo che avrebbero dato valori sicuramente superiori
Tra il pensare e il fare in architettura: le arti del disegno e le metodologie BIM nella gestione del cantiere
No full textThere is, in Architecture, an intellectual responsibility that involves each author-designer about the relationship between time of conception and practical realization; the cycle of construction activities is a crucial stage in this production
process. The most advanced procedures of Building Information Modeling (BIM) are an added value not only for
the design but also for operations and controls on site during construction.
To assess dynamics, opportunities and achievements of representation language supported by BIM technologies we will expose some experiments carried out by the research group who have achieved significant savings in production and adopted important amendments to construction process
First assessment of plasticizers in marine coastal litter-feeder fauna in the Mediterranean sea
No full textMicro and nanoplastics are harmful to marine life due to their high level of fragmentation and resistance to degradation. Over the past two decades, marine coastal sediment has shown an increasing amount of microplastics being a sort of trap for debris wastes or chemicals. In such an environment some species may be successful candidates to be used as monitors of environmental and health hazards and can be considered a mirror of threats of natural habitats. Such species play a key role in the food web of littoral systems since they are litter-feeders, and are prey for fishes or higher trophic level species. A preliminary investigation was conducted on five species of small-sized amphipod crustaceans, with the aim to understand if such an animal group may reflect the risk to ecosystems health in the central Mediterranean area, recently investigated for seawater and fish contamination. This study intended to gather data related to the accumulation of plasticizers in such coast dwelling fauna. In order to detect the possible presence of xenobiotics in amphipods, six analytes were scored (phthalic acid esters and non-phthalate plasticizers), identified and quantified by the gas chromatography mass spectrometry (GC-MS) method. The results showed that among all the monitored contaminants, DEP and DiBP represented the most abundant compounds in the selected amphipods. The amphipod crustaceans analyzed were a good tool to detect and monitor plasticizers, and further studies of these invertebrates will help in developing a more comprehensive knowledge of chemicals spreading over a geographical area. The results are herein presented as a starting point to develop baseline data of plasticizer pollution in the Mediterranean Sea
