Sisto V e il palazzo Colonna ai santi Apostoli
No full textThe author investigates the reasons of the strong interest of Pope Sixtus V for aquiring the Palazzo della Torre, property of the Colonna family, belonging to the oldest aristocracy of Rome, even against the will of Cardinal Ascanio Colonna, who had inherited it from his father, the famous Marcantonio of the battle of Lepanto. Sixtus wished to give back the Palazzo to the Franciscan Convent of Santi Apostoli not only as a sign of his affection but mainly to accomplish a new urban project for the eastern part of Rome, from the hill of the Qurinale to the Piazza delle Terme, near his familiar Villa Peretti Montatlto
Studio di sistemi di conservazione per il prolungamento della shellf-life di finocchi freschi.
No full textQuesta ricerca ha riguardato lo studio del prolungamento della shelf-life dei finocchi mediante la refrigerazione e l'impiego di imballaggi attivi. Inoltre, poiché i processi di imbrunimento enzimatico ne limitano mediamente la conservabilità a soli 2-7 giorni, é stata valutata la possibilità di impiego di inibitori dell'attività polifenolossidasica per rallentare le alterazioni a carico delle superfici sottoposte a stress traumatici. Lo studio é stato effettuato sia confezionando il prodotto mediante adsorbenti addizionati con etanolo, sia confezionando i finocchi senza adsorbenti, ma pretrattandone il torsolo con una soluzione acquosa allo 0,01% di una sostanza ad azione antiossidasica, antiossidante ed antimicrobica, nonché inibente della produzione di etilene. Le prove condotte hanno consentito di prolungare la shelf-life dei finocchi fino a 14 giorn
THE DROOPING TIP The role of the Pitanguy’s ligament in the position of the nasal tip
No full textThe nasal tip is the “mobile” portion of the nose, unlike the nasal pyramid, which is the fixed component. The tip’s anatomical characteristics are determined by intrinsic factors, such as the volume, shape, definition and morphology of the alar cartilages, which, together with the subcutaneous tissue, can profoundly influence the configuration and dynamics of this nasal region. The position of the tip is therefore the result of a complex interaction between size, morphology, position and dynamism of various anatomical components of the lower third of the nose.
Two fundamental aspects must be considered in modelling the tip: the projection and rotation, which can be modified by acting on the nose’s cartilaginous structures and on the superficial fibromuscular nasal structure (SMAS). The superficial muscoloaponeurotic system (SMAS) is a dynamic and complex fibromuscular layer able to support and mobilise the osteocartilaginous structure of the nasal pyramid and, moreover, influence the functionality of the nasal valve.
This chapter analyses the changes of rotation and projection of the tip, assessing the role taken by the deep medial ligament of the muscoloaponeurotic system (SMA-DML) of the nose, which corresponds, according to many, with the so-called Pitanguy’s ligament in determining the position
Combinatorial algorithms for feedback problems in directed graphs
No full textGiven a weighted directed graph G = (V, A), the minimum feedback arc set problem consists of finding a minimum weight set of arcs A' subset of or equal to A such that the directed graph (V, A A') is acyclic. Similarly, the minimum feedback vertex set problem consists of finding a minimum weight set of vertices containing at least one vertex for each directed cycle. Both problems are NP-complete. We present simple combinatorial algorithms for these problems that achieve an approximation ratio bounded by the length, in terms of number of arcs, of a longest simple cycle of the digraph.

La collezione del cardinale Pietro Aldobrandini nella villa a Monte Magnanapoli
No full textThe author investigates the reasons why cardinal Pietro Aldobrandini decided to build a new Roman villa
in the lower part of the Quirinale in Rome at the beginning of XVII Century. Primarily he needed it to host
his well-known collection of paintings, whose famous part were those robbed in Ferrara in 1598. The distinguished
elegant and sober building seems to be conceived expressly to favor the exhibition of the works of
modern and ancient art possessed by cardinal Pietro, so to demonstrate the birth of a new way to collect art
objects, based on relevant stylistic comparisons among masterpieces of the different “Maniere”
Vittore Carpaccio tra narrazione e devozione
No full textThe author discusses the reasons why late Carpaccio has often been considered unable to gain the same success
reserved to his contemporaries as Giorgione, Sebastiano del Piombo or the young Titian at the beginning of
XVI Century, concluding that this was mainly due to Carpaccio’s traditional patrons. They clearly preferred
works of art connected to late XV Century Venetian pictorial tradition, probably also because of the difficult
and dangerous situation of the Republic from the economic and political point of view, but this doesn’t mean
that he wasn’t sincerely appreciated, as can testify even his last works
Numana and its ancient territory: new data and research perspectives
No full textNumana is one of the most important centers for the Picenian civilization and prospered in the Marche and Abruzzo regions during the Iron Age. Almost all of the archaeological evidence found until now refers to the necropoleis spread over a broad territory, while data concerning inhabited areas are quite scarce. Although findings are plenty, the study of Ancient Numana is quite incomplete. As a matter of fact, all the published materials are related to single burials or finds and there are no overall studies on its territory. A recent research project involving a wider sector of the largest Numana necropolis (Quagliotti-Davanzali), has not been published yet but offers a detailed description since the excavation documentation is available. The project sets out to consider burials as organized systems, offering information on cultural transformations and on the social organization of the ancient community. The systematic analysis of the data from the burial and the single funerary sets - to be organized in a specific GIS - will be accompanied by an investigation of the ancient landscape in its many components - necropolis and inhabited area - in its diachronic development, thanks to the results of other recent analyses carried out in the Numana territory (geomorphology, GIS of the archaeological map, new surveys of the territory). The scope of the project is therefore to analyze times, ways of arrangements, shapes of the Ancient Numana, in its definition of a territorial, inhabited, rural space, by using methods and techniques to record and read new data, to build knowledge in a scenario which can be integrated with results coming from future research
LE VERNICI INDUSTRIALI PER LEGNO: UN APPROFONDIMENTO NORMATIVO ED UNO STUDIO SULLE POTENZIALITÀ IN ALCUNE ECONOMIE EMERGENTI
No full textIl lavoro di tesi si collega al tema delle strategie di crescita ed espansione internazionale delle medie imprese italiane. L’industria di riferimento è quella dei prodotti vernicianti per legno; i mercati internazionali analizzati sono la Polonia, il Brasile e la Turchia.
La tesi si articola in quattro capitoli, per la cui stesura, oltre alle fonti bibliografiche e normative, sono utilizzati dati ed informazioni sia di mercato sia di industria sia aziendali correlati al Dottorato Industriale svolto presso il Gruppo ICA. Il lavoro è infatti il frutto di un percorso triennale reso possibile dalla collaborazione tra Regione, Università e aziende del territorio, che hanno stipulato protocolli di intesa volti a finanziare percorsi formativi e di esperienza lavorativa per giovani laureati.
Il tema affrontato nel lavoro di tesi si caratterizza per una sua immediata attualizzazione in quanto rappresenta la necessità di bilanciare interessi economici ed ambientali spesso in contrasto tra loro: la comunità internazionale infatti ha legiferato su un settore complesso e caratterizzato da dinamiche spesso contrapposte, che vedono da una parte operatori economici interessati allo sviluppo del settore, dall’altra la necessità di porre l’accento su tematiche ambientali, dalle cui conseguenze gli operatori economici non possono più prescindere.
Nel primo capitolo del lavoro, attraverso l’analisi del quadro normativo ambientale di riferimento in materia di emissioni indoor delle vernici e del loro principale ambito di utilizzo nei settori industriali, si mette in luce la potenziale dannosità di questi prodotti nell’interazione con l’ambiente, con i lavoratori e con l’utilizzatore finale.
Nel secondo capitolo si descrive la PRODCOM, la principale nomenclatura statistica comunitaria sui prodotti industriali, e quella delle principali classificazioni internazionali ad essa connesse, in particolare, l’International Standard Industrial Classification (ISIC) e le classificazioni ONU “product-based” dei prodotti industriali. Scopo del capitolo è di eseguire un’analisi dettagliata sulle nomenclature in uso nei principali Paesi e territori, al fine di fornire uno strumento utile per l’analisi macroeconomica degli Stati oggetto di studio.
Dopo aver descritto il mercato mondiale delle vernici industriali per legno, analizzando le principali tipologie di prodotti ed i principali produttori di vernici su scala mondiale, nel terzo capitolo si analizza il settore dell’industria del mobile e del mobile in legno. Si esamina il valore della produzione nelle principali nazioni protagoniste nel legno-arredo, in particolare Usa, Cina, Unione Europea. In questa parte dello studio è risultato fondamentale il supporto dei dati e delle informazioni raccolte durante l’esperienza di Dottorato Industriale nel Gruppo ICA.
Nell’ultimo capitolo, si espone l’analisi strategica dei mercati relativi a Polonia, Brasile e Turchia, messi a confronto con l’Italia, nell’ottica di una potenziale scelta d’investimento in loco da parte di un’azienda italiana. Attraverso una panoramica sull’attuale presenza del Gruppo ICA nei Paesi di riferimento ed un’analisi macroeconomica, si quantifica la produzione nei settori a valle e si analizza la competizione nel settore core, definendo per ciascuna nazione il potenziale nell’ambito del parquet, dei mobili, delle porte, delle finestre e delle case in legno. Nei settori a valle l’interesse è legato al valore della produzione di quei beni, mentre per il settore core si analizza la domanda (consumo).This Thesis project is connected with the internationalization strategies and processes of Italian medium-sized enterprises. The industrial wood coatings market and its main downstream sectors of use are our target industries. Furthermore, it delivers a strategical study of these industries in three growing economies: Poland, Brazil and Turkey, taking Italy as a confrontational tool.
The work is organized in four chapters, supported by bibliographical and legal sources as well as market information and economic data. Practical approach is also guaranteed by the industrial PhD experience of the author in the company ICA Group. The project is the result of the collaboration among Marche Region, local Universities and local enterprises. The agreement process has led to a joint funding process for young graduates.
The work addresses current global issues like the need to balance economic and environmental themes, where several often contradictory interests are at the stake. The international community legislated in a complex sector, characterized by opposing trends. On one side economic operators tend to maximize profits and continue to develop the sector, on the other environmental issues and challenges connected to these activities has become priorities in international debate.
The first part of the thesis highlights potential threats and dangers of these products while interacting with the environment, with workers and end-users. This objective is reached, firstly, analysing environmental legal framework connected to indoor emissions of paints and varnishes, both national, foreign, EU-based and on voluntary basis. Secondly, providing a definition of paint product and its main application field in downstream industrial sectors.
The second phase, instead, describes the main European statistical classification on manufactured goods, the PRODCOM. In addition, an overview of two main international statistical nomenclatures is also delivered: the International Standard Industrial Classification (ISIC) and the UN list of Industrial Products. The aim of this chapter is to compute a detailled study of the statistical classification used in the main countries and economic territories, in order to deliver a useful tool for macroeconomic analisys of the selected countries.
After having examined in depth the world industrial wood coatings market, analysing the main type of products and biggest world producers, we proceed with the study of the furniture industry and the wooden furniture industry, providing production value estimates of the main leading nations, particularly, United States, China and EU. At this point, the support of several statistical data and info’s collected during my PhD experience in ICA Group proved to be crucial.
Last section is dedicated to deliver results of the strategic study on downstream sectors connected with the use of wood coatings, separately in three countries (Poland, Brazil and Turkey), taking Italy as a confrontational tool. This analysis will help the Management of a potential italian company to make a strategic decision on foreign investments.
We are going to quantify values and historical trends in sectors connected with the use of wood coatings, such as the construction industry, wood flooring, furniture, wooden windows and doors, prefabricated wooden buildings industry. In addition, a macroeconomic overview of the selected countries is also provided as well as a study of the existing competition in the three wood coatings markets. In downstream industries, we are going to provide data on production, while in the “core” industry (wood coatings) we are going to analyse data on demand (market)
