Il Building Information Modelling nasce da un processo di integrazione sostenibile, basato sull'interoperabilità dei processi. La caratteristica vincente è la circolarietà delle informazioni: ogni informazione è gestita come parametro di un ricco e complesso modello parametrico dell'edificio; la geometria, i materiali, i costi ed i tempi sono gestiti come parametri internamente collegati e quindi variabili di uno stesso sistema. Nel caso di beni storici, la maggior parte degli edifici possiede vincoli intrinseci che influenzano tali parametri. I materiali non possono essere scelti liberamente, in quanto parte di un organismo esistente, la geometria dell'edificio è definita e difficilmente sarà variata negli interventi di recupero. Nella presente tesi si applica il metodo CLOUD2FEM al mondo dell'Historic Building Information Modelling (HBIM) concentrandosi sullo studio della Rocca Estense di San Felice sul Panaro, colpita dal sisma dell'Emilia e attualmente inagibile. La procedura CLOUD2FEM permette di trasformare le informazioni ricavate dal laser scanner in mesh chiuse e regolari, generando in modo semi-automatico un modello FEM 3D. Nel caso di costruzioni complesse, la cui geometria non può essere ricondotta a modelli semplificati, è necessario valutare l'attendibilità del modello strutturale. Nel caso in esame, la validazione è stata condotta mediante il confronto del danno rilevato con il danno simulato. La flessibilità del modello permette di aggiungere dettagli inizialmente non rilevati: ogni informazione è inserita nel modello attraverso un parametro differente, al fine di eseguire analisi sullo stato di fatto e su futuri stati di progetto con semplice aggiornamento dei parametri.

(ITA) L’industria mondiale odierna nel campo dell’architettura e dell’ingegneria si esprime quasi esclusivamente mediante l’approccio BIM, Building Information Modeling. Anche se sviluppato pensando alle nuove costruzioni ed ancora in via di perfezionamento, è entrato prepotentemente nei capitoli normativi di molti stati all’urlo dell“interoperability”. Su questo tema è recente l’interesse e la possibilità di adozione per l’intervento sul costruito, ovvero di Existing Building Information Modelling, eBIM. Gli studi applicativi-sperimentali in questo ambito sono sempre più numerosi e convergono, purtroppo, sulla delicata correlazione tra la gestione del contenuto semantico e la perdita di interoperabilità. Questa tesi si incentra sull’analisi di tale correlazione valutando in particolare l’aspetto metodologico-applicativo dell’arricchimento semantico adottando come caso studio la Torre Nord della Rocca Estense di San Felice sul Panaro. (ENG)Today's global industry in architecture and engineering fields, expresses itself almost entirely focusing on BIM, Building Information Modeling. Even though it was developed taking in consideration new buildings and the ones that are in the process of improvement, it has entered the regulatory chapters of many states in the hymn of "interoperability". Concerning this topic is recent the interest and possibility of adopting a process to intervene on the already built constructions, Existing Building Information Modeling, eBIM. Application-experimental studies in this area are increasingly numerous and unfortunately converge, on the delicate correlation between the management of the semantic content and the loss of interoperability. This thesis focuses on the analysis of this correlation by evaluating in particular the methodological-applicative aspect of semantic enrichment by adopting the North Tower of the Rocca Estense in San Felice sul Panaro as a case study.

In questa tesi si propone una metodologia per il trasferimento interattivo semiautomatico di dati da modelli geometrici semantici sviluppati in ambiente BIM a modelli strutturali supportati da analisi per elementi finiti. Il caso della Rocca estense di San Felice sul Panaro, gravemente danneggiata dagli eventi sismici del 2012, è utilizzato come caso di studio applicativo. La metodologia prevede in prima battuta la modellazione di elementi speciali BIM quali contenitori locali dei dati semantici definiti mediante regioni nello spazio del modello che individuano particolari condizioni fisiche individuate mediante la definizione di opportuni metadati. Successivamente, tali informazioni vengono processate automaticamente, mediante uno script integrato in ambiente BIM, rendendole compatibili con i set di dati che tipicamente vengono trasmessi in input per analisi ad elementi finiti. Tali operazioni permettono quindi la generazione di un modello strutturale che recepisce direttamente le attribuzioni semantiche del modello geometrico iniziale. Nell'elaborato sono inoltre discusse alcune metodologie alternative per la generazione del modello agli elementi finiti, partendo da diverse definizioni geometriche in ambiente BIM.

Building Information Modelling is changing the design and construction field ever since it entered the market. It took just some time to show its capabilities, it takes some time to be mastered before it could be used expressing all its best features. Since it was conceived to be adopted from the earliest stage of design to get the maximum from the decisional project, it still struggles to adapt to existing buildings. In fact, there is a branch of this methodology that is dedicated to what has been already made that is called Historic BIM or HBIM. This study aims to make clear what are BIM and HBIM, both from a theoretical point of view and in practice, applying from scratch the state of the art to a case study. It had been chosen the fortress of San Felice sul Panaro, a marvellous building with a thousand years of history in its bricks, that suffered violent earthquakes, but it is still standing. By means of this example, it will be shown which are the limits that could be encountered when applying BIM methodology to existing heritage, moreover will be pointed out all the new features that a simple 2D design could not achieve.

This work describes the evaluation of metals and (metallo)proteins in vitreous humor samples and their correlations with some biological aspects in different post-mortem intervals (1-7 days), taking into account both decomposing and non-decomposing bodies. After qualitative evaluation of the samples involving 26 elements, representative metal ions (Fe, Mg and Mo) are determined by inductively coupled plasma mass spectrometry after using mini-vial decomposition system for sample preparation. A significant trend for Fe is found with post-mortem time for decomposing bodies because of a significant increase of iron concentration when comparing samples from bodies presenting 3 and 7 days post-mortem interval. An important clue to elucidate the role of metals is the coupling of liquid chromatography with inductively coupled plasma mass spectrometry for identification of metals linked to proteins, as well as mass spectrometry for the identification of those proteins involved in the post-mortem interval.

Troglobitic (exclusively subterranean) organisms usually present, among their apomorphies related to the subterranean life (troglomorphisms), the regression of eyes and melanic pigmentation. The degree of regression varies among species, from a slight reduction to the complete loss of eyes and dark pigmentation, without a taxonomic correlation. While mechanisms of eye reduction have been intensively investigated in some troglobites such as the Mexican blind tetra characins, genus Astyanax, and the European salamander, Proteus anguinus, few studies have focused on pigmentation. The Brazilian subterranean ichthyofauna distinguishes not only by the species richness (23 troglobitic fishes so far known) but also by the variation in the degree of reduction of eyes and pigmentation. This study focused on Brazilian fishes completely devoid of melanic pigmentation: the characiform Stygichthys typhlops (Characidae) and the siluriforms Ancistrus formoso (Loricariidae), Rhamdiopsis sp.1 (Heptapteridae; from caves in the Chapada Diamantina, Bahia) and Rhamdiopsis sp. 2 (cave in Campo Formoso, Bahia). In order to investigate if such depigmentation is the result of blockage in some step in the melanogenesis, in vitro tests of administration of L-DOPA were done, using caudal-fin fragments extracted from living fish. Except for Rhamdiopsis sp. 2, all the studied species were DOPA(+), i.e., melanin was synthesized after L-DOPA administration. This indicates these fish do have melanophores but they are unable to convert L-tyrosine to L-DOPA. On the other hand, Rhamdiopsis sp. 2, like the albino specimens of Trichomycterus itacarambiensis previously studied (which correspond to one third of the population), are DOPA(-), either because the block of melanin synthesis occurs downstream in melanogenesis, which is probably the case with T. itacarambiensis (monogenic system in view of the phenotypic discontinuity), or because the so-called albinos do no possess melanophores. The physiological loss in the ability to synthesize melanin, apparently caused by different genetic processes in DOPA(+) and in DOPA(-) fishes, may co-exist in subterranean populations with a decrease in the density of melanophores, as observed in the pigmented two thirds of T. itacarambiensis population, a morphological reduction apparently controlled by polygenic systems producing a continuous phenotypic variation.

Conclusion: The cochlear implant was beneficial as an attempt to restore hearing and improve communication abilities in this patient with profound sensorineural hearing loss secondary to Susac syndrome. Objective: To report the audiological outcomes of cochlear implantation (CI) in a young woman with Susac syndrome after a 6-month follow-up period. Susac syndrome is a rare disorder. It is clinically characterized by a typical triad of sensorineural deafness, encephalopathy, and visual defect, due to microangiopathy involving the brain, inner ear, and retina. Methods: This was a retrospective review of a case at a tertiary referral center. After diagnosis, the patient was evaluated by a multidisciplinary team and received a cochlear implant in her right ear. Results: The patient achieved 100% open-set sentence recognition in noise conditions and 92% monosyllable and 68% medial consonant recognition in quiet conditions after 6 months of implant use. She reported the use of the telephone 3 months after activation.

Este trabalho visou a comparar o potencial energético de resíduos produzidos no beneficiamento de grãos de café (Coffea canephora var. Conilon) e no processo de fresamento da madeira, sugerindo seu uso em substituição ao da lenha de eucalipto, no processo de secagem de grãos de café. O uso destes resíduos agrícola e florestal pode contribuir para a redução de problemas ambientais relacionados com a contaminação do solo, ar e água, devidos a seu descarte inadequado, e para reduzir os custos de produção e, ou, beneficiamento do café. Os subprodutos da destilação seca e o carvão vegetal dessas matérias-primas foram quantificados e comparados. De acordo com os resultados, pôde-se verificar que os resíduos de casca de café proporcionaram uma boa produção de carvão vegetal, visto que seu rendimento gravimétrico em carvão foi estatisticamente superior ao da lenha. Considerando a produtividade e qualidade do carvão vegetal, o melhor resultado foi obtido pela carbonização da casca de café nas temperaturas de 350 ºC a 550 ºC e dos resíduos da fresa de madeira a 550 °C, principalmente, graças aos rendimentos médios em carbono fixo, que, nesses casos, superaram aqueles apresentados pelos carvões derivados de lenha do eucalipto. Em se tratando do poder calorífico superior, verificou-se que os resíduos da fresa de madeira e os resíduos de casca de café poderão ser utilizados para secagem de grãos de café, visto que apresentaram valores de poder calorífico superior (PCS) muito próximo aos de lenha de eucalipto. Graças aos bons rendimentos gravimétricos e rendimentos em carbono fixo, os carvões vegetais derivados dos resíduos produzidos no beneficiamento de grãos de café e no processo de fresamento da madeira apresentaram potencial considerável para serem utilizados como insumo energético.

This paper presents value added estimates for the Italian regions, in benchmark years from 1891 until 1951, which are linked to those from official figures available from 1971 in order to offer a long-term picture. Sources and methodology are documented and discussed, whilst regional activity rates and productivity are also presented and compared. Thus some questions are briefly reconsidered: the origins and extent of the north-south divide, the role of migration and regional policy in shaping the pattern of regional inequality, the importance of social capital, and the positioning of Italy in the international debate on regional convergence, where it stands out for the long run persistence of its disparities.

The article is composed of two sections. The first one is a critical review of the three main alternative indices to GDP which were proposed in the last decades – the Human Development Index (HDI), the Genuine Progress Indicator (GPI), and the Happy Planet Index (HPI) – which is made on the basis of conceptual foundations, rather than looking at issues of statistical consistency or mathematical refinement as most of the literature does. The pars construens aims to propose an alternative measure, the composite wealth index, consistent with an approach to development based on the notion of composite wealth, which is in turn derived from an empirical common sense criterion. Arguably, this approach is suitable to be conveyed into an easily understandable and coherent indicator, and thus appropriate to track development in its various dimensions: simple in its formulation, the wealth approach can incorporate social and ecological goals without significant alterations in conceptual foundations, while reducing to a minimum arbitrary weighting.
