La scoperta, sistemazione e conservazione della grande Iscrizione di Gortina, nell'isola di Creta (1884-1921): la protezione delle testimonianze e le…

2013

La scoperta e la conservazione della Grande Iscrizione di Gortina a Creta, da parte degli studiosi italiani, fra la fine del XIX sec. e i primi decenni del XX sec., rappresentò un grande riconoscimento scientifico-culturale per la giovane nazione italiana. Nel passato, l’isola di Creta era stata legata alla Repubblica di Venezia e anche questo rapporto favorì l’invio a Creta del giovane epigrafista F. Halbherr, il quale fra notevoli peripezie rinvenne, assieme all’epigrafista tedesco E. Fabricius, la famosa l’iscrizione nell’antica città di Gortina. L’iscrizione, fra le più antiche e complete finora conosciute in tutta Europa, conteneva le norme sulla famiglia, l’eredità e in generale i dir…

The discovery and preservation of the Great Inscription of Gortyna in Crete by Italian researchers in the late nineteenth century. and the first decades of the twentieth century. was an important cultural and scientific recognition for the young Italian nation. In the past the island of Crete had been tied to the Republic of Venice and this report also favored sending in Crete the young epigraphist F. Halbherr who among considerable vicissitudes came to together to the epigraphist german E. Fabricius the inclusion of the famous ancient city of Gortyna. The inscription among the oldest and most comprehensive so far known throughout Europe the rules contained on the family's legacy in general and the rights and duties of some of the people of the Minoan civilization (480-450 BC). The inscription was carved on blocks organic limestone a restored ancient building which later in Roman times was turned into odeon. The Laws of Gortyn were engraved on the remains of the wall forming the passageway in front of the steps of the odeon. The essay traces the events that led to the discovery and subsequent storage made by Halbherr especially with the help of archaeologist L. Pernier and finally with the help of architect E. Stefani who designed a modern cover on the top of the ambulatory of the segments containing the inscription. This coverage was made to perform during the First World War on the basis of the Italian project from the Greek Government in order to protect the membership from possible war damage but especially from vandalism. The roof brick clay of the Laws of Gortyna still serves its function and ensures the use of the monument bearing witness to the preservation of Italian culture in Greece and more generally in the world. But in Sicily in the remains of the Villa del Casale in Piazza Armerina (Enna) its elegant protection (built in 1957) is representative of a whole period of culture of the Italian restoration is removed and replaced because it has not been able to make a ongoing maintenance is due. A bad example of conservation and management of a UNESCO monument from which arise after the work for the construction of new roofs an equally insulting to the archaeological heritage and scenic Italian and world.Settore ICAR/19 - Restauro

Rapid and eco-friendly synthesis of graphene oxide-silica nanohybrids

2014

The increasing interest in Graphene oxide (GO) is due to many issues: the presence of both sp2-conjugated atoms and oxygen-containing functional groups provides a strong hydrophilicity and the possibility to further functionalize it with other molecules (i.e. π-π interactions covalent attachment etc.) [1]. Furthermore since the GO is biocompatible and noncytotoxic many studies have been recently focused on the development of GO-based nanodevices for bioimaging DNA detection drug delivery. Due to their low cytotoxicity and large internal surface area silica nanoparticles have been taken into account as promising material for biolabeling and drug loading/delivery. Particular consideration has recently been demonstrated for GO-silica composites because of the potentialities for electrical applications their chemical inertia and stability toward ions exposure. The possibility to combine the extraordinary properties of GO and silica offers several advantages for the realization of nanoprobes for biological applications and of biosensor [12]. The strategy for the fabrication of GO-nanosilica nanohybrids can be schematized as follows: (i) synthesis of GO by oxidizing graphite powder with the method described by Marcano et al. [3] (ii) Preparation of oxygen-loaded silica nanoparticles by thermal treatments in controlled atmosphere in order to induce high NIR emission at 1272 nm from high purity silica nanoparticles. (iii) preparation of GrO-silica nanohybrid films via rapid solvent casting in water. The nanohybrids were tested by XPS FTIR Raman analysis UV photoluminescence analysis TGA Zeta potential measurements electrical tests AFM and SEM. Several nanohybrids were prepared by combining two different typologies of GO and two different samples of silica.

Integrazione di celle fotovoltaiche ibride nel vetromattone

2012

L’invenzione riguarda l’integrazione del vetromattone con celle solari ibride (organiche/inorganiche), conosciute come Dye-sensitized Solar Cell (DSC). La combinazione del vetromattone con le DSC consente di migliorare le prestazioni del prodotto originario rendendolo in grado di produrre energia pulita. Le caratteristiche di trasparenza e isolamento termo-acustico del prodotto possono essere regolate agendo sulla configurazione delle DSC. Il prodotto può essere assemblato a formare pannelli fotovoltaici per la realizzazione di facciate traslucide energeticamente “attive” in varie condizioni luminose (condizioni di luce diffusa o artificiale) e indipendentemente dall’angolo di radiazione so…

The integration of Dye-sensitized Solar Cell (DSC) with the glassblock is disclosed. The combination of the two technological elements the glassblock and the DSC module enhance their own peculiarities. The final complete product is ready-made for installation owns the qualities of the glassblock and produces sustainable energy at the same time. The transparency and the thermo-acoustic insulation may be modulated according to the specific requirements of each case of installation. The product may be used for example to create PV panels for glazed and translucent façades that are able to perform efficiently in all light conditions (even in diffuse light also converting internal artificial light) that are not dependant on the angle of the solar radiation and do not suffer from the high operative temperatures of functioning due to the peculiarities of the DSCs. DSCs are made of economic and biocompatible materials and are produced with low-cost and highly productive printing methods on rigid or flexible substrates. With the integration of DSC modules with the glassblock PV panels coincide with the envelope itself so that they do not need any further structures to be installed on and allow the possibility of subtract from the price of the panel the price of the substituted building element allowing further economies. DSCs can be printed in different colours and with various patterns offering to designers and customers the possibility of intervening on the glassblock aesthetical aspect also taking advantage of the peculiar modularity of the glassblock for larger compositions of drawings on the building’s façade. Seven Hypotheses of integration are discussed in order to obtain DSC-integrated glassblock ready for the construction of a precast and dry-assembled PV panel which can use the horizontal and vertical cavities between the glassblocks to house plastic profiles where the electric interconnections and the steel bars -useful for improve the mechanical resistance of the panel- are integrated.Settore ICAR/10 - Architettura Tecnica

Ambiente e diritto penale: brevi riflessioni fra le modifiche agli artt.9 e 41 Cost. e le prospettive di riforma in ambito internazionale

2023

l contributo analizza l’impatto che il recente inserimento dell’ambiente in Costituzione può dispiegare in ambito penale, tanto rispetto all’ambiente quale oggetto della tutela penale, quanto sul versante della selezione dei modelli di illecito, soffermandosi in particolare sul problema delle possibili ricadute penalistiche del nuovo vincolo di solidarietà ecologica di tipo intergenerazionale. Seguendo il fil rouge del bene giuridico, la seconda parte del saggio ricostruisce invece i punti critici e le prospettive di sviluppo del diritto penale ambientale internazionale, alla luce della nozione di ambiente quale bene giuridico comune ed universale.

The paper analyses the impact that the recent inclusion of the environment in the Italian Constitution may have in the criminal law both with respect to the criminally relevant notion of the environment and with regard to the selection of the types of criminal offences. From this point of view the paper also takes into consideration the penal significance of the new bond of intergenerational ecological solidarity. Following the file rouge of the “bene giuridico” the second part of the essay is instead dedicated to the description of the critical points and the possible developments of international environmental criminal law in the light of a conception of the environment as a common and universal legal good.Settore IUS/17 - Diritto Penale

Droghe leggere e criminalità organizzata: una relazione problematica

2022

Il contributo analizza il tema dei rapporti tra trattamento penale delle droghe c.d. “leggere” e contrasto alla criminalità organizzata dedita al narcotraffico, con riguardo all’ordinamento europeo, internazionale e di alcuni Paesi dell’UE (Spagna, Portogallo, Grecia, Germania e Italia). Seguendo un approccio di tipo integrato, all’analisi del dato normativo si affianca la descrizione della fenomenologia dei traffici e la valutazione dei primi effetti che le riforme antiproibizioniste entrate in vigore in alcuni ordinamenti del Nord e del Sud America hanno prodotto sul fronte del mercato illecito. Il fine è di evidenziare i punti di forza e di debolezza dei modelli di depenalizzazione, tene…

The paper analyses the relationship between the criminal treatment of 'soft' drugs and the fight against organised crime related to drug trafficking with regard to European law international law and national criminal law of some EU countries (Spain Portugal Greece Germany and Italy). Following an integrated approach the analysis is carried on taking into consideration the phenomenology of trafficking and an assessment of the initial effects that the anti-prohibitionist reforms of some North and South American jurisdictions have produced on the illicit market. The aim is to highlight the strengths and weaknesses of the de-criminalisation models taking into account not only their theoretical profiles but also possible outcome on the fight against organised crime.Settore IUS/17 - Diritto Penale

Interventistica eco-guidata per l’articolazione d’anca

2013

Lo scopo di questo lavoro è di rivedere le principali applicazioni della interventistica eco-guidata d’anca, descrivendone le indicazioni e la metodologia. L’ecografia è una metodica considerata sicura per i pazienti, in quanto non è stato dimostrato un possibile danno dovuto all’energia trasmessa dagli ultrasuoni ai tessuti del paziente, contrariamente alle metodiche che fanno uso di radiazioni ionizzanti, come la radiografia convenzionale e la tomografia computerizzata. Inoltre, l’ecografia risulta rapida ed efficace nel guidare l’ago verso la sede voluta evitando di intercettare strutture vascolari e/o nervose, consentendo quindi una maggiore sicurezza, rispetto alle tecniche interventis…

The purpose of this work is to review the main applications of ultrasound-guided hip intervention al procedures describing the indications and methodology. Ultrasound is a method considered safe for patients as it has not been shown a possible damage due to ultrasound energy transmitted towards the patient's tissues as opposed to methods that make use of ionizing radiation such as conventional radiography and computed tomography. In addition ultrasound is quick and effective in guiding the needle to the desired location avoiding vascular and/or nerve structures thus enabling greater security compared to the techniques performed in interventional fluoroscopy which also have the disadvantage of a large delivery of ionizing radiation for both patient and operator. Several authors have described the main techniques of ultrasound-guided hip intervention and its various applications that can be both diagnostic (as in the case of joint fluid aspiration to assess the presence or absence of septic arthritis) and therapeutic (as in the case of drugs inoculations or evacuation of exceeding intra-articular fluid).

Epistemic and didactic values of the demonstrative process in different cultures: a case study in Geometry with Chinese and Italian students

2011

This paper presents same key findings of the research project conducted by G.R.I.M. of Palermo on the approaches to justification and proof in Geometry by investigating how Chinese and Italian teachers and students taught particular geometrical topics refereed to different epistemic and didactic values related to own culture. It was found that Chinese teachers and students emphasized justification of the proof by a stressed visual verification based on some metarules linked with the structure of their own written language and defined as historical Chinese modus operandi in the Jiuzhang Suanshu. The Italians paid close attention to mathematical proof by a hypoxemic deductive system defined on the Euclide’ Elements. The geometrical problem discussed on the paper was defined and presented as “one problem multiple solution problems” and “one problem multiple changes”. Important aspect of the case study discussed in the paper focus on the mediation of knowledge between Chinese and Italian students involved in multicultural class. According to us these kind of activities can establish possibilities for the students to confront their self with different cultural social and educational prospective of knowledge discovering the power of mathematics as tool of negotiation in multicultural class?Settore MAT/04 - Matematiche Complementari

Fazioni e popolo in una provincia del dominio pontificio fra XIII e XIV secolo

2021

Between the 13th and 14th centuries, a number of cities in the inchoative papal state experimented a system of self-government that allowed the Guelph and Ghibelline factions, formally represented in those same bodies on an equal footing, to work alongside the more strictly communal magistracies. The case of Todi is rather well known, given the role that Bartolo da Sassoferrato assigns to it in his Tractatus de guelphis et gebellinis (ca. 1350), but current research has already ascertained that this political tradition appeared at least around 1260. Some evidence can suggest, however, that some form of integration of factions into the local institutional framework was possible elsewhere, an…

Tra XIII e XIV secolo alcune città dello stato della chiesa in formazione sperimentano un regime di autogoverno che prevede accanto agli organi più propriamente comunali la presenza delle fazioni guelfa e ghibellina formalmente rappresentate in quegli stessi organi in modo paritario. Il caso di Todi è piuttosto noto data la funzione che Bartolo da Sassoferrato gli assegna nel suo Tractatus de guelphis et gebellinis (1350 circa) ma la storiografia ha già appurato che questa tradizione politica durava dal 1260 circa almeno. Alcuni indizi fanno ritenere che però la possibilità di una qualche forma di integrazione delle fazioni nel quadro istituzionale locale avvenisse anche altrove e non lontano ad Amelia a esempio. Qui nel nuovo statuto di popolo 1343 troviamo la ripartizione su base fazionaria dei ruoli del priorato. A Todi nel 1337 era avvenuto qualcosa di analogo: lo statuto emanato quell’anno fa seguito all’instaurazione di un regime esplicitamente popolare che in continuità con la tradizione locale integra al suo interno guelfi e ghibellini. Gli esempi di queste e forse altre comunità della provincia del Patrimonio di san Pietro in Tuscia possono così aggiungere qualche elemento utile alla discussione sul problema delle fazioni e del loro ruolo nell’ordine politico comunale e post-comunale e in particolare sul rapporto fra popolo come sistema istituzionale e parti.Settore M-STO/01 - Storia Medievale
