Viene qui indagata la dinamica della fortuna del tema di Vesta, nume tutelare focolare sacro, e delle sue sacerdotesse, le Vestali. Partendo dagli scritti di eruditi, quali Pirro Ligorio e Ulisse Aldrovandi, passando per l’analisi di alcuni repertori figurativi rinascimentali, grazie anche allo spoglio degli inventari, si sono rintracciate Vesta e Vestali nelle principali collezioni: Colonna, Porcari, Mattei, Pichi, Paluzzi Albertoni, Farnese, Lisca, Belvedere Vaticano, Cesi, Orsini, Soderini, Medici, Altieri, Ludovisi, Giustiniani, Pamphilj, Massimo, Chigi, Carpegna. Nel Cinquecento le grandi opere di scavo promosse da personaggi influenti portarono alla scoperta di sculture, monete e rilievi riconosciute come tali anche grazie alla riscoperta dei testi classici utili a ricostruire la storia antica di Roma, e al sito di rinvenimento. Nel Seicento i dettami suggeriti per il restauro da Orfeo Boselli portarono ad integrare le statue oltre che come Vestali anche come Muse o Igea etc. Solo gli scavi, condotti nell’Atrium Vestae da Rodolfo Lanciani alla fine dell’Ottocento, hanno permesso di far luce sullo spazio dedicato alle Vestali e sul loro aspetto. Altre utili precisazioni sono emerse dalla riconsiderazione della storia degli scavi a Roma dal XV al XVII secolo, nel Campo Marzio, sull’Esquilino, nell’area degli Horti Asiniani e di Porta Capena, sull’Aventino, nell’area Lateranense e sul Gianicolo, siti di provenienza di molte delle antichità considerate. Inoltre il ritrovamento nel XIX secolo, nell’area delle Terme di Caracalla, di una statua di divinità seduta, che è stata messa a confronto con la Vesta del Dodekatheon di Ostia e con la statua seduta del boschetto del Belvedere, può forse contribuire a far luce sulla statua che Plinio vide negli Horti di Asinio Pollione. Prendendo a confronto l’affresco con Vesta ritrovato a Pompei nel pistrinum una casa privata, si potrebbe infine avanzare l’ipotesi che anche a Roma in ambiti privati possa essere stato creato uno spazio celebrativo, consacrato alla divinità del focolare, nel quale forse trovarono posto alcune delle sculture considerate o anche i rilievi con offerenti provenienti dall’area del Laterano.
Here we wish to study the fortunate dynamic of the “theme” of Vesta, tutelary divinity of the sacred hearth, and of her priestesses, the Vestals. Beginning with the literary sources of Pirro Ligorio and Ulisse Aldrovandi, continuing through the analysis of various Renaissance sketchbooks, and thanks also to the perusal of the inventories of the various collections, Vesta and the Vestal Virgins have been found in all of the most important collections of antiquities, as for example, those of the Colonna, Porcari, Mattei, Pichi, Paluzzi Albertoni, Farnese, Lisca, Belvedere Vaticano, Cesi, Orsini, Soderini, Medici, Altieri, Ludovisi, Giustiniani, Pamphilj, Massimo, Chigi, Carpegna. In the 16th century the great archaeological excavations, promoted by influential personalities, brought about the discovery of sculptures, coins and reliefs, recognized like that, thanks also to the rediscovery of the classical texts, useful for the reconstruction of the history of ancient Rome, and to the sites of discovery. On the other hand, during the 17th century, changes were felt in the artistic climate, so Orfeo Boselli suggested the restorations of statues like Vestals or Muses or Igea. Only through Lanciani’s excavations in the Atrium Vestae, at the end of the 19th century, we have been able to shed light on the area dedicated to the Vestal Virgins and on their appearance. Other useful information emerged thanks to the re-examination of the history of the archaeological excavations conducted in Rome, from the 15th to the 17th centuries, in Campo Marzio, the Esquiline Hill, the Horti Asiniani, Porta Capena, the Aventine Hill, the Lateran zone, and the Janicolo Hill, sites from which many of the antiquities being studied were excavated. In addition, the rediscovery in the 19th century, in the Baths of Caracalla, of a statue with a seated deity, which has been compared with the Vesta on Dodekatheon and with the seated statue in the Vatican Gardens, can perhaps contribute to shed light on the statue which Pliny saw in the Horti Asiniani When we consider the fresco showing Vesta, found in a pistrinum in a private home in Pompei, we can advance the hypothesis that also in Rome, in private residences, there may have been created sacred areas, dedicated to Vesta, the divinity of the hearth, where perhaps some of the sculptures we have taken into consideration, or perhaps the reliefs that come from the Lateran area showing the faithful bearing offerings, may have been placed.

La ricerca ha per oggetto la memoria delle Vergini Vestali Emilia, Claudia e Tuccia nei Facta et Dicta Memorabilia di Valerio Massimo. L'obiettivo è indagare il valore esemplare attribuito dallo storico tiberiano a queste figure: Valerio Massimo selezione, infatti, una serie di esempi attraverso i quali indirizzare il suo pubblico all'applicazione di comportamenti e atteggiamenti conformi all'ideologia patrocinata dal principe Tiberio. La tesi studia il profilo biografico di queste tre donne, attraverso la testimonianza di Valerio Massimo e, in ottica comparativa, delle altre fonti antiche che ne conservano memoria, mettendo in luce differenze e analogie e, quindi, individuando le scelte nella conservazione del ricordo effettuate dallo storico. Come necessaria premessa, la ricerca ricostruisce le linee fondamentali dell'ideologia tiberiana e il metodo di lavoro e le finalità dell'opera di Valerio Massimo.

The cult of Vesta was vital to the city of Rome. The goddess was associated with the City’s very foundation, and Romans believed that the continuity of the state depended on the sexual and moral purity of her priestesses. In this dissertation, Virgin Territory: The Vestals and the Transition from Republic to Principóte, I examine the Vestal cult between c. 150 BCE and 14 CE, that is, from the beginning of Roman domination in the Mediterranean to the establishment of authoritarian rule at Rome. Six aspects of the cult are discussed: the Vestals’ relationship with water in ritual and literature; a re-evaluation of Vestal incestum (unchastity) which seeks a nuanced approach to the evidence and examines the record of incestum cases; the Vestals’ extra-ritual activities; the Vestals’ role as custodians of politically sensitive documents; the Vestals’ legal standing relative to other Roman women, especially in the context of Augustus’ moral reform legislation; and the cult’s changing relationship with the topography of Rome in light of the construction of a new shrine to Vesta on the Palatine after Augustus became pontifex maximus in 12 BCE. It will be shown that the cult of Vesta did not survive the turmoil of the Late Republic unchanged, nor did it maintain its ancient prerogative in the face of Augustus’ ascendancy. The thesis therefore sheds new light on our understanding of the nature, role and significance of the Vestal cult during the Roman revolution.

Les astéroïdes Cérès et Vesta ont motivé la mission spatiale Dawn parce qu'ils représentent deux embryons planétaires différents restés relativement intacts depuis leur formation. Vesta est large- ment considéré comme le corps parent des météorites HED témoins d'une activité magmatique probablement due à la présence de l'isotope radioactif 26Al qui était suffisamment abondant pour permettre la fusion interne des corps rocheux primitifs. La composition d'une surface planétaire peut être mesurée grâce à l'analyse des rayons gammas qu'elle produit. Pour la sonde Dawn cela est rendu possible par l'instrument GRaND et la scintillation d'un cristal de BGO. Cette thèse présente l'analyse des spectres gammas de Vesta par deux outils de séparation aveugle de source: l'analyse en composantes indépendantes (ICA) et la factorisation en matrice non-négative (NMF). Ces méthodes sont aussi appliquées à un jeu de données lunaire comparable et déjà bien interprété. Des spectres synthétiques lunaires permettent de tester ICA et NMF. La séparation de spectres élémentaires s'avère délicate même si on peut distinguer les éléments K, Th et Fe en raison des propriétés statistiques de leur signaux sources plus favorables. On mesure la sensibilité d'ICA-NMF à la variabilité chimique de la surface pour des Lunes artificielles, ce qui permet d'expliquer l'absence de séparation d'un signal élémentaire clair dans le cas de Vesta. Malgré les observations de la sonde Dawn et le nombre important d'informations fournies par les HED, il n'y a pas de consensus sur la formation des HED. On met souvent en avant l'existence d'un océan magmatique global sur Vesta, alors que la migration de la principale source chaleur, contenue dans le premier minéral fondu, le plagioclase, ne permet pas la fusion totale. On met en oeuvre un modèle de migration des magmas, basé sur les équations de la compaction. On adapte ce modèle en utilisant un diagramme d'équilibre de phase olivine-anorthite-quartz. Cela permet de calculer l'évolution de la minéralogie en fonction du temps et de la profondeur. Les résultats montrent que les eucrites et les diogénites pourraient être une caractéristique commune des gros corps accrétés tôt dans l'histoire du système solaire
Asteroids Vesta and Ceres motivated the space mission Dawn because they represent two different planetary embryos that remained relatively intact since their formation. Vesta is broadly considered as the parent body of the HED meteorites suite that are witnesses of a magmatic activity probably due to the presence of the radioactive isotope 26 Al which was present in significant amount to cause internal melting of primitive rocky bodies. The composition of a planetary surface can be quantified through the analysis of the gamma rays it produces. This is made possible for the Dawn spacecraft by the instrument GRaND and the scintillation of a BGO crystal. This thesis presents the analysis of gamma ray spectra from Vesta by two blind source separation methods: the independent component analysis and the non negative matrix factorization. These methods are also applied to an equivalent lunar dataset already well interpreted. Lunar synthetic spectra are used to test ICA and NMF. The separation of elementary spectra is delicate although K, Th and Fe can be discriminated due to the more favorable statistical properties of their source signals. The sensitivity of separation to the chemical variability is assessed based on artificial lunar spectra, which allows to explain the lack of separation of a clear elemental signal in the case of Vesta. Despite the observations of Dawn and the important collection of HED data, there is no consensus on the conditions of the vestan magmatism. A global magma ocean is often put forward, whereas the migration of the heat source, contained in the easiest mineral to melt, plagioclase, does not allow it. A model of melt migration is implemented, based on two-phase flow equations. This model is combined with the olivine-anorthite-quartz equilibrium phase diagram. This allows to predict the mineralogy as a function of depth and time. Results obtained show that eucrites and diogenites may be a common feature of large bodies accreted early in solar system history

Lo scopo di questa tesi è quello di descrivere e fare una sorta di analisi critica della società cinese contemporanea usando come parametro di riferimento uno tra gli elementi base di questa: l'abbigliamento. Verrà sottolineata l'importanza dell'uso dell'abito come abitudine inconsapevole e innata dell'essere umano inserito in un determinato contesto sociale. La tesi, tramite riferimenti alla psicologia del vestiario e all'analisi del gusto (inteso come come indicatore/parametro di stile di vita e di identità sociale), descriverà i cambiamenti che si sono susseguiti in quest'ambito in un contesto prima europeo, poi cinese. In un secondo momento si analizzerà la moda in Cina a partire dai primi anni del diciannovesimo secolo, per introdurre i cambiamenti che sono avvenuti, nell'ambito del vestiario, dopo che il Paese ha intrapreso un processo di riforme. Verrà descritto qual'è stato il cambio di mentalità nei confronti dell'abito, in che modo questo sia potuto accadere (sia tramite l'esposizione ai media come la televisione, le riviste o internet sia in virtù delle varie influenze dei contesti europeo-americano e giapponese-coreano) e quali sono le caratteristiche delle nuove figure di designer cinesi emergenti. Si passerà quindi a illustrare come sia avvenuta l'apertura della Cina dopo le riforme e di come ne siano derivate nuove classi sociali, con le loro problematiche, necessità e tendenze. Si farà riferimento soprattutto ai nuovi ricchi cinesi e ai loro gusti per arrivare a descrivere le figure dei manager che si fanno sempre più promotori di arte, stile di vita e cultura e, come tali, sono ispiratori e allo stesso tempo fruitori della moda. Nell'ultima parte verrà esposto un case study su Uma Wang, intesa come stilista cinese emergente, rappresentativa delle nuove tendenze della società cinese che si apre in un contesto mondiale globalizzato.

L'espèce Plutella xylostella (L.) (Lepidoptera : Plutellidae) défoliatrice des choux constitue surtout un problème dans les régions tropicales et subtropicales. La lutte chimique a rapidement montré ses limites du fait de l'apparition de résistance dans les populations. Des moyens de lutte alternatifs ont été mis en place, impliquant principalement des insectes parasitoïdes, parmi lesquels Oomyzus sokolowskii (Kurdjumov) (Hymenoptera : Eulophidae) et Cotesia vestalis (Haliday) (Hymenoptera : Braconidae) qui sont les plus couramment utilisés en raison de leur spécificité envers P. xylostella. Afin de contribuer à une meilleure connaissance du contrôle de la teigne en région tropicale, nous avons étudié les relations hôteparasitoïde entre P. xylostella et O. sokolowskii d'une part, et P. xylostella et C. vestalis d'autre part, en conditions de laboratoire et sur le terrain au Sénégal et au Bénin. Au Sénégal, quatre espèces de parasitoïdes sont présentes sur les chenilles : O. sokolowskii, Apanteles litae, C. vestalis et Brachymeria citrae. Au Bénin, seule l'espèce C. vestalis est présente. Au Sénégal comme au Bénin, les facteurs climatiques contribuent au développement de la teigne et les précipitations ne régulent pas les populations du ravageur. Dans ces deux pays, la teigne n'est pas contrôlée par ses ennemis naturels. La lutte biologique par conservation y est à prendre en considération et l'utilisation de plantes compagnes cultivées en association avec le chou peut être envisagée pour réduire les populations de la teigne. Les études en laboratoire ont montré qu'Oomyzus sokolowskii est un parasitoïde larvo-nymphal performant. ConcernantC. vestalis, les femelles détectent et reconnaissent leur hôte grâce aux lipides cuticulaires émis par les chenilles. Des marqueurs moléculaires (isozymes et ISSR) ont confirmé une forte variabilité entre les populations de P. xylostella à l'échelle mondiale, les populations d'Australie et du Japon étant très différentes des autres et formant deux groupes distincts. La structuration des populations semble influencée par le type de climat : tropical et non tropical.

Corporation Social Responsibility (CSR) has been growing in its importance, which makescompanies under great pressure with the handling of CSR and making it a useful managerial tool.This thesis tries to answer the questions of whether the E.ON Group, Vestas, ExxonMobil, andthe Shell Corporation are using the appropriate CSR communication strategies, and whether ornot a company’s relative environmental friendliness affects the CSR communication strategy ofsaid company, and was written to increase our understanding of CSR communication as aconcept. We adopted an inductive stance, with a constructionist, interpretivist point of view, andso decided to perform qualitative research by way of a comparative case study.We then collected our data from the corporate websites of the two companies, and analyzed itaccording to Carroll’s CSR pyramid, Morsing’ theories on stakeholder communication strategy,and the theory on credibility as defined by Greek philosopher Aristotle. Once analyzed, wecompared the data gathered from the two companies to each other in order to draw ourconclusions.In the end, we concluded that E.ON’s and Vestas’ CSR communication strategy are quitelacking, while Shell’s and Exxon’s CSR communication strategy are quite the successes. Thisthen actually seems to answer our second question, as Shell, who is leagues less environmentallyfriendly than E.ON, devotes a lot more focus towards their CSR communication measures.Moreover, it is through our study that we have discovered a lack of academic theories or modelguiding for a successful use of CSR communication.

The shape and gravity field are fundamental properties of a planetary body. Combining gravity and topography data sets is, arguably, the most powerful tool to study planetary interiors from orbit. However, even when gravity and topography data are in hand, typically, a wide range of possible geophysical structures is possible. The reader will find that this problem of non-unique solutions permeates all chapters of this thesis. The general strategy to reduce non-uniqueness is to find ways to use additional observations that are sensitive to the interior structure but are not degenerate with gravity and/or topography. In this work, we study three Solar System bodies: asteroid Vesta, dwarf planet Ceres and the Earth's Moon. Using the data from the Dawn spacecraft, we find that once hot and hydrostatic, Vesta is no longer either. It was despun by two giant collisions. We use the Dawn gravity/topography data along with meteoritic data to provide constraints on Vesta's internal structure. Unlike Vesta, Ceres is close to hydrostatic equilibrium. Based on Ceres' topographic spectrum, we conclude that it has experienced limited viscous relaxation. Contrary to the pre-Dawn expectations, we find that the cerean crust is mechanically rock-like. We provide constraints on Ceres' rheology and density structure by combining gravity/topography data with finite-element modeling of lithospheric relaxation. Additionally, we find that Ceres' obliquity undergoes large oscillations, which has important implications for volatile transport. The GRAIL mission has produced gravity models of the Moon with an unprecedented accuracy. We study the spectral content of gravity models and characterize their effective resolution to provide users of these models with the information necessary to understand the model limitations.

Le sujet de cette thèse est l'étude de la rotation à long terme des corps célestes.La première partie est consacrée à l’étude de la rotation à long terme de Cérès et Vesta, les deux corps les plus massifs de la ceinture principale d’astéroïdes. Ils sont l’objet d’étude de la sonde spatiale Dawn, qui a permis de déterminer précisément les caractéristiques physiques et de rotation nécessaires au calcul de leurs rotations. La distribution de glace sous et à la surface de Cérès dépend du mouvement de son axe de rotation par le biais de l’obliquité, inclinaison de l’équateur sur l’orbite. Les rotations de Cérès et Vesta étant rapides, l’évolution à long terme des axes de rotation de Cérès et Vesta a été obtenue à l'aide d'une intégration symplectique des équations de la rotation, où une moyenne a été réalisée sur la rotation propre rapide. La stabilité des axes de rotation de Cérès et Vesta a été étudiée en fonction des paramètres de la rotation avec un modèle séculaire semi-analytique, qui a permis de montrer que les axes de rotation ne présentaient pas de caractère chaotique.La seconde partie concerne le développement d'intégrateurs symplectiques dédiés au corps solide. L'intégration de la rotation propre d'un corps solide nécessite d’intégrer les équations issues du hamiltonien du corps solide libre. Ce hamiltonien est certes intégrable et présente une solution explicite nécessitant l’usage des fonctions elliptiques de Jacobi, cependant le coût numérique de ces fonctions est élevé. Lorsque le hamiltonien du corps solide libre est couplé avec une énergie potentielle, l’orientation du corps doit être calculée à chaque pas d’intégration, ce qui augmente le temps de calcul. Des intégrateurs symplectiques ont ainsi été précédemment proposés pour le corps solide libre. Dans ce travail, des intégrateurs spécifiques au corps solide ont été développés en utilisant les propriétés de l’algèbre de Lie du moment cinétique
This thesis concerns the long-term rotation of celestial bodies.The first part is a study of the long-term rotation of Ceres and Vesta, the two heaviest bodies of the main asteroid belt. The spacescraft Dawn studied these two objects and determined the physical and rotational characteristics, which are necessary for the computation of their rotations. The ice distribution under and on the surface of Ceres depends on the evolution of the obliquity, which is the inclination of the equatorial plane on the orbital plane. As the rotations of Ceres and Vesta are fast, the long-term evolution of the spin axes of Ceres and Vesta was obtained by realizing a symplectic integration of the equations of the rotation averaged on the fast proper rotation. The stability of the spin axes of Ceres and Vesta was studied with respect to the parameters of the rotation with a secular and semi-analytical model, which allowed to show that the spin axes are not chaotic.The second part concerns the development of symplectic integrators dedicated to the rigid body. The integration of the proper rotation of a rigid body needs to integrate the equations given by the Hamiltonian of the free rigid body. This Hamiltonian is integrable and presents an explicit solution using the Jacobi elliptic functions. However, the numerical cost of these functions is high. When the Hamiltonian of the free rigid body is coupled to a potential energy, the orientation of the body is needed at each step, which increases the computation time. Symplectic integrators were then previously proposed for the free rigid body. In this work, symplectic integrators dedicated to the rigid body were developed using the properties of the Lie algebra of the angular momentum

This dissertation presents improvements made on position estimation techniques applied to seismology, airborne gravimetry and planetary gravity recovery. In Chapters 2 and 3, a smoothed ionospheric model computed using GPS phase observations was applied to seismology and airborne gravimetry. The seismic investigation observed the 2010 El Mayor-Cucapah earthquake near Baja, California. The application of the ionospheric model resulted in an overall 4 mm RMS reduction in the measurements of GPS heights. The same ionospheric technique was applied to GPS data collected during an airborne gravity survey. In this study the model improved the RMS spread of four repeat gravity profiles by 0.6 mGal. Chapters 4 and 5 focus on the Dawn mission to the asteroid 4 Vesta. Chapter 4 details the use of spacecraft image constraints in the orbit determination software GEODYN, which is used by NASA/GSFC for trajectory reconstruction and geophysical analyses of planets. Image constraints are shown to converge an orbit solution that differs from that computed by the Dawn Science Team at JPL by less than 13 m. Chapter 5 describes the application of the new technique in the estimation of the orientation parameters and low-degree gravity field of Vesta. The pole orientation and low-degree gravity field estimated agree with that presented by the Dawn Science Team through the use of an independent software and estimation algorithm.

L'automobile constituant, en milieu urbain, la principale source de pollution atmosphérique, la question se pose de savoir quels sont les effets sur la santé, à court ou à long terme, des polluants liés aux émissions automobiles. Des études épidémiologiques devraient permettre de répondre à cette question à condition de pouvoir disposer d'une évaluation adéquate de l'exposition des individus étudiés à cette pollution atmosphérique d'origine automobile (PAA), exposition présente mais également passée. En France, les chercheurs du Centre Scientifique et Technique du Bâtiment (CSTB) et de l'Institut National de Recherche sur les Transports et leur Sécurité (INRETS) ont mis au point l'Indice ExTra d'exposition au trafic routier, indice qui repose sur des modèles physico-mathématiques de dispersion de polluants (OSPM et CALINE3). Cet indice permet de classer précisément les lieux de séjour des individus en fonction des concentrations extérieures de polluants auxquelles ils sont soumis, puis de reconstituer l'exposition cumulée de chaque personne devant ces différents lieux de séjour, avec une pondération par le temps passé dans ces lieux. Il n'est, bien sûr, envisageable d'utiliser un tel indice dans le cadre d'études épidémiologiques, qu'après l'avoir validé. Cette recherche avait deux objectifs : 1) valider l'indice ExTra, 2) l'appliquer dans le cadre de l'étude épidémiologique VESTA (V Epidemiological Studies on Transport and Asthma). La validation de l'indice ExTra a été effectuée sur 100 sites exposés à des niveaux contrastés de PAA, dans quatre villes partenaires de l'étude VESTA : Grenoble, Nice, Paris et Toulouse. Les coefficients de corrélation obtenus entre les valeurs des concentrations mesurées et calculées valent, par ville, respectivement : 0,90 ; 0,95 ; 0,89 et 0,89. Par ailleurs, l'application aux enfants inclus dans VESTA a consisté à estimer, à partir du modèle retenu précédemment, leur exposition à la PAA, présente et cumulée jusqu'à la date de point. Les 403 enfants ont été en moyenne exposés à 70 ± 42 æg. M -3 de NOx équivalent NO2 dont 14 ± 22 æg. M -3 attribuables au trafic de proximité. Outre la validation du modèle pour les concentrations en oxydes d'azote et la description des expositions des enfants de VESTA, les résultats obtenus en menant une analyse discriminante par arbres de classification ont permis d'émettre des recommandations sur la pertinence de l'utilisation de l'indice (plutôt que de la pollution de fond fournie par les réseaux) en fonction de l'histoire résidentielle des individus, notamment en considérant le maximum du trafic et le trafic moyen pondéré au domicile ainsi que le minimum de la distance du domicile à son vis-à-vis et le minimum de la distance au trafic du lieu de garde ou de scolarité. .
Automobile exhaust is a major source of air pollution in urban areas. For studying short and long term health effects of this traffic air pollution (TAP) epidemiologists have to determine precisely exposure to such pollution to avoid misclassification. In France, the ExTra index produced by the French Scientific Center for Building Physics (CSTB) and the French National Institute for Transport and Safety Research (INRETS), estimates ambient concentrations of transport-related pollutants in front of the work and living places of urban dwellers. These estimates, combined with time-activity diaries, enable individual exposure to these pollutants in front of these living places to be assessed. Two pollutant dispersion models are used to calculate the ExTra index : the Danish model OSPM (Operational Street Pollution Model) and the CALINE3 model (California Line Source Dispersion Model). Before being applied to large scale epidemiological studies such as the VESTA study (a French multicentric case-control study on asthma), the ExTra index needs to be validated. This research had two goals : 1) to validate the ExTra index, 2) to apply this index to the VESTA study (V Epidemiological Study on Transport and Asthma). The validation study of the ExTra index was performed in four of the French towns participating in the VESTA study. This validation was based on the comparison of nitrogen oxide concentrations (NOx) obtained by measurement against those obtained from calculations, using the ExTra index and the OSPM model. The model was tested at 100 street canyon sites. Then, we used the ExTra index to assess lifelong nitrogen oxides concentrations the 403 study children were exposed to in front of their living places. This assessment highlighted significant disparities : mean ExTra index values and share attributable to proximity traffic were respectively 70 ± 42 and 14 ± 22 æg. M -3 NOx equivalent NO2 for the 403 children. Beyond the validation of the ExTra index for NOx concentrations and the description of the VESTA children's TAP exposures, the results obtained by a discriminant analysis (with classification trees) gave us guidelines for the use of this index (rather than background pollution levels provided by the networks) according to the different residence and school characteristics of a subject throughout his (her) life. .

The particular study case in this thesis is the shock test performed on the LISA Pathfinder satellite conducted in a laboratory environment on a dedicated test bed: Vega Shock Test Apparatus (VESTA). This test is considered fully representative to study shock levels produced by fairing jettisoning event at Vega Launcher Vehicle, which induces high shock loads towards the satellite. In the frame of this thesis, some transient response analyses have been conducted in MSC Nastran, and a shock simulation tool for the VESTA test configuration has been developed. The simulation tool is based on Nastran Direct Transient Response Analysis solver (SOL 109), and is representative of the upper composite of Vega with the LISA Pathfinder coupled to it. Post-processing routines of transient response signals were conducted in Dynaworks which served to calculate Shock Response Spectra (SRS). The simulation tool is a model of forcing function parameters for transient analysis which adequately correlates with the shock real test data, in order to understand how the effect of shock generated by the launcher is seen in the satellite and its sub-systems. Since available computation resources are limited the parameters for analysis were optimised for computation time, file size, memory capacity, and model complexity. The forcing function represents a release of the HSS clamp band which is responsible for fairing jettisoning, thus the parameters which were studied are mostly concerning the modelling of this event. Among many investigated, those which visibly improved SRS correlation are radial forcing function shape, implementation of axial impulse, clamp band loading geometry and refined loading scheme. Integration time step duration and analysis duration were also studied and found to improve correlation. From each analysis, the qualifying shock environment was then derived by linear scaling in proportion of the applied preload, and considering a qualification margin of 3dB. Consecutive tracking of structural responses along shock propagation path exposed gradual changes in responses pattern and revealed an important property that a breathing mode (n = 0) at the base of a conical Adapter translates into an axial input to the spacecraft. The parametrisation itself was based on responses registered at interfaces located in near-field (where the clamp band is located and forcing function is applied) and medium-field with respect to the shock event location. Following shock propagation path, the final step was the analysis of shock responses inside the satellite located in a far-field region, which still revealed a very good correlation of results. Thus, it can be said that parametrisation process was adequate, and the developed shock simulation tool can be qualified. However, due to the nature of shock, the tool cannot fully replace VESTA laboratory test, but can support shock assessment process and preparation to such test. In the last part of the thesis, the implementation of some finite element model improvements is investigated. Majority of the panels in spacecraft interior exhibited shock over-prediction due to finite element model limitation. Equipment units modelled as lump masses rigidly attached with RBE2 elements to the panel surface are a source of such local over-predictions. Thus, some of the units were remodelled and transient responses were reinvestigated. It was found that remodelling with either solid elements, or lump mass connected to RBE3 element and reinforced by RBE2 element, can significantly improve local transient responses. This conclusion is in line with conclusions found in ECSS Shock Handbook.

Il presente lavoro ha voluto analizzare in modo sistematico il quadro istituzionale della città di Lanuvium in età romana, esaminando l’organizzazione della città dalla sua incorporazione nello stato romano, fino al suo declinio. La ricerca è fondata sull’esame delle fonti letterarie ed epigrafiche. La struttura amministrativa della città, le sue istituzioni politiche e religiose, le magistrature, i sacerdozi, i collegia, le numerose curiae, non erano state mai oggetto di un esame analitico, rimanendo sospese tra numerose ipotesi, spesso tra loro scollegate e mai veramente focalizzate in uno studio d’insieme. Queste nuove indagini e prospettive di ricerca sulle istituzioni politiche e religiose di Lanuvium sono un primo tentativo di affrontare la difficile realtà istituzionale di una delle città più interessanti del Latium vetus
This studies aims to systematically analyze the institutional framework of the city of Lanuvium in Roman times, examining the organization of the city since its incorporation into the Roman state, to its decline. The research is based on examination of the literary and epigraphic sources. The city’s administration, its political and religious institutions, the magistracies, the priesthoods, the collegia, and several curiae, had never been examined analytically, and remained suspended between several assumptions often unrelated to each other and never really focused in an overall study. These new investigations and research perspectives on political and religious institutions of Lanuvium are a first attempt to address the difficult institutional reality of one of the most interesting cities of Latium vetus

The dynamical evolution of the spin axis direction due to gravitational and thermal factors is examined. It is found that the spin axis variations generally are regular and relatively small for the bodies in the asteroid main belt. There are also reasons to believe that this is the case for minor objects beyond the main belt. However, it is found that these regular variations are larger when the orbital inclination of the objects is increased. This effect may explain certain features in the spin vector distribution of the main belt asteroids, not possible to explain by collisional factors. The spin vector evolution of the asteroids in the inner solar system, including the Earth- and Mars-crossing objects, is often subjected to strong forces related to frequencies in the orbital evolution. The variations in the spin vector direction are then very large and often subjected to chaos. The larger frequency related obliquity zones of the Mars-crossers are usually regular while the zones of the Earth-Mars-crossers often are of a chaotic nature. The spin vector evolution of asteroids with comet-like orbits is often chaotic regardless of initial obliquity. For the inner solar system asteroids, it is often possible for an initial prograde spin to turn into a retrograde one, or vice versa, due to the frequency related phenomena. Though some spin vector directions seem to be more probable than other ones over time, there are no indications for an evolution towards a more prograde or a more retrograde spin vector distribution.

The effects on the spin vector evolution from the thermal Yarkovsky force are examined for objects with radii larger than 50 m. This force will affect the orbital evolution and thus indirectly affect the spin vector evolution. However, it is found that the studied effects are minor as compared to the gravitationally related ones. This is true both for the diurnal and the seasonal variants of the Yarkovsky force.

Dalla scoperta del grafene, molte ricerche sono state condotte sui cosiddetti “materiali 2D”. Questo elaborato si focalizza sulle proprietà strutturali, elettroniche, ottiche ed eccitoniche di due materiali bidimensionali, ossia il grafene il disolfuro di molibdeno (MoS2-1H), quest’ultimo un importante semiconduttore. Le proprietà di questi materiali sono diverse rispetto alla loro controparte massiva (bulk) grafite e MoS2-2H, e un loro confronto è stato preso in considerazione. Come metodo di indagine sono state scelte simulazioni quanto- meccaniche ab initio dei sistemi in esame, un approccio che, negli ultimi decenni, sta avendo un impatto sempre più importante sulla fisica, sulla chimica dello stato solido e sulla scienza dei materiali, promuovendo non solo una comprensione più profonda, ma anche la possibilità di contribuire in modo significativo alla progettazione di materiali per nuove tecnologie. Questo importante passo avanti è stato possibile grazie a: (i) una descrizione migliorata ed efficiente degli effetti elettronici a molti corpi (many-body) nella teoria del funzionale della densità (DFT), nonché lo sviluppo di metodi post-DFT per lo studio di proprietà specifiche; (ii) un’accurata implementazione di questi metodi in software altamente efficienti, stabili e versatili, capaci di sfruttare il potenziale delle architetture informatiche moderne. Tra i possibili software ab initio basati su DFT, abbiamo scelto il pacchetto di simulazione di Vienna ab initio VASP, considerato un gold standard per questo tipo di indagini. I risultati ottenuti per le varie proprietà di bulk e di superficie (bidimensionale) dei materiali scelti sono in ottimo accordo con dati ottenuti in precedenza, sia a livello teorico, sia sperimentale. Questo elaborato getta quindi le basi per futuri studi nel campo dei materiali 2D per comprendere, analizzare, ingegnerizzare nuovi materiali con proprietà desiderabili e per sviluppare nuove applicazioni degli stessi.

La presente ricerca è stata volta ad esaminare il linguaggio iconografico che le città utilizzavano per rappresentarsi. L’immagine della dea Tyche, in quanto protettrice e personificazione di città, è stata a lungo utilizzata dalle città, sia in periodo ellenistico che romano, per una rappresentazione iconografica del loro status. Il modello iconografico di Tyche è stato indagato nella sua relazione con i vari gradi di indipendenza delle città del mondo greco-orientale, in periodo ellenistico e romano, mostrando una chiara ideologia politica alla base dell’utilizzo del modello. Partendo dall’analisi una moneta proveniente da Seleucia al Calicadno, in Cilicia, regione dell’attuale Turchia, vengono presi in esame i concetti giuridici fatti persona, con particolare attenzione al tema dell’integrazione delle città orientali nella romanità, mettendo anche in evidenza i cambiamenti determinati dall’editto dell’imperatore Caracalla. L’immagine di Tyche serviva anche da tema mitico connesso ai miti di fondazioni delle città, sia in ambito microasiatico, dove si era inserita nella mitologia delle Amazzoni eponime di città, sia nel mondo romano con la fondazione di Roma o di Lavinio, rappresentate nei fregi del Museo Nazionale Romano (provenienti dalla Basilica Aemilia e dal Colombario della gens Statilia sull'Esquilino), sia nel mondo orientale e africano, con i paralleli provenienti dal Niger e dall'area balcanica. La raffigurazione dell’elemento femminile a protezione della città risultava codificato iconograficamente nel modello della dea Tyche e delle numerose divinità che condividevano con la dea questo ruolo protettivo, quali Tutela, Genius, Cybele, la Dea Roma. Lo stesso elemento femminile si ritrova archeologicamente presente nelle sepolture rituali sotto le mura o le porte delle città. Le sepolture e le uccisioni rituali hanno avuto un carattere apotropaico e hanno messo in relazione l’elemento femminile con la fondazione della città. Questa chiave di lettura aiuta a comprendere la morte per seppellimento delle Vestali incestae, e il luogo della loro sepoltura presso la porta della città, luogo carico di significato simbolico. I capitoli della ricerca prendono in esame aspetti diversi dell’immagine della Tyche, che segna il filo conduttore dello studio, mostrando l’importanza, nel mondo antico, dell’iconografia della dea come modello di autorappresentazione da parte delle città dell’impero, e da parte della stessa Roma.
The present research exams the iconographical language used by cities representing themselves. The image of Goddess Tyche, as city protectress and city personification has been used for a long time by cities, in Hellenistic and roman times, representing their status. The iconographical model of Tyche has been investigated in its relationship with the various degrees of independence of the cities in the greek-oriental word, in Hellenistic and Roman period, showing there was a political ideology behind. The analysis of a coin from Seleucia on the Calycadnus, Cilicia (Turkey), shows the use of juridical concepts, with particular attention to the problems of integration and romanization of the greek cities. The situation changed after the Constitutio Antoniniana emanated by Emperor Caracalla. The image of Tyche also served as foundation myth for the cities, in micro-asiatic area or in roman area, as we can see on friezes in the Museo Nazionale Romano (Rome), from the Basilica Aemilia and Colombarius Esquilinus. The idea of a woman as city protectress is based on the iconographical model of Tyche, and many divinities shared with the goddess this protective role as Genius, Cybele, Dea Roma and the Amazons. The same female element is archeologically found in ritual burials under city boundaries , in particular under city walls and city gates. The burials and the ritual killings had an apothropaical function and connected the female element with the city foundation. This is reading key to understand the burial of the Vestals incestae, and the place of their burial near the city wall. The research exams the different uses of the image of Tyche, showing the iconographical importance of the goddess as representation of the cities in Roman Empire and in Rome itself.

This dissertation focus is the analysis of a possible merger of two wind turbine manufacturers, Vestas and Gamesa. The proposed deal will have has business background the trend for market consolidation, as well the down trend of both firms market share and market value, being the wind power sector still with attractive prospects,. For this proposal, it is combined a deep industry and company analysis with the state of the art valuation tools. Literature on Valuation and M&A is reviewed and applied to evaluate the standalone and merged businesses, proposing an optimal transaction structure. The whole analysis relies on data until end of 2011, being performed estimated for both companies’ standalone and the combined firm, for a growth and stable period. Data from comparables and market benchmarks where also collected for different tools usage. The merged firm with synergies will generate a high increase in the equity value. Net synergies are estimated to be around 67% attributable to Vestas and 33% to Gamesa in the combined firm value. Therefore, it is concluded that the deal will create a sustainable value both firms’ shareholders by issuing a new leading company.

The goal of this Thesis is to evaluate Vestas Wind Systems A\S. For this purpose, the current valuation methodologies were discussed. The conclusion was to use three valuation methodologies. Firstly, the Discounted Cash Flow methodology was performed due to its acceptability both among researchers and professionals. Three scenarios were created to account for the uncertainty tied with the cyclicality of the business, and probabilities were assigned based on the economical reasonability of each. A final price of kr. 300,51 was reached, implying that the firm is undervalued (market prices kr. 250). Secondly the Economic Value Added approach was conducted, providing insight on the periods in which the company is able to generate economic profit. The three scenarios were also used. The final price of kr. 356,62 was reached yielding a buy opportunity. Thirdly the multiples valuation was performed in order to better understand the industry and the company’s peers. A forward looking enterprise value to EBIT multiple was used and a final price of kr. 302,01, also implying that the company is undervalued. In addition a Value at Risk analysis was performed to access the risk of our recommendation. Finally our valuation target price (from 300 to 360) was compared with the valuation from Skandinaviska Enskilda Banken, and reached the conclusion that although results are similar, methods and business assumptions differs.

The use of water in Roman private houses has been identified as a highly visible status symbol. The detailed study of the House of the Vestals at Pompeii reveals how water features were central to the house¿s structural changes from the late first century B.C. The owners of the house invested heavily in fountains and pools as key elements in the display of their wealth to visitors and passers-by alike. This article relates the structural development of the House of the Vestals to the social history of decorative water usage, from an initial investment exploiting the pressurized water provided by the new aqueduct early in the Augustan period to the responses to crises following the earthquake of A.D. 62

To detect the more original state of minor planets, now there is one mission exploring the main asteroids belt, Dawn Mission, and the destinations are Vesta, Ceres, and maybe Pallas. At the orbit between Mars and Jupiter, the region that main asteroids belt locates can be divided by the well-known boundary, snowline. Although the existence of water ice on Vesta hasn’t been found yet, many researches (cf. Fanale and Savail, 1987; Bar-Nun et al., 1989; Schorghofer, 2008) simulate the amount of water ice survived under dust mantle in the main asteroids belt. This thesis applies the 3D exospheric model, 3D thermal model and ray tracing to simulate the survival rate of water ice on Vesta. Moreover, the seasonal effect on Vesta makes the diurnal temperature different, which also changes the region of adsorption and cold traps. The proposed ray tracing model can be used to compute the seasonal change of solar radiation flux which dominates the diurnal temperature. However, the mean free path of molecules in the exosphere of Vesta is dominated by the gravity. Since the shape of Vesta is not spherical, the proposed exospheric model also applies the elliptical gravity.

Asteroid 4 Vesta, the largest differentiated body in the asteroid belt, is a protoplanet, much like those that accreted to form the Earth. Understanding the geology of Vesta furthers understanding of early differentiation processes that occurred on Earth and helps define igneous processes occurring on other differentiated bodies in the early solar system. Howardite, eucrite and diogenite (HED) meteorites, which are thought to have originated from Vesta, can be analyzed to better understand the geology of that asteroid. Here my colleagues and I investigate the petrology and geochemistry of two groups of HEDs. This work is timely, in that the insights gained from these studies can be used to interpret data from the Dawn spacecraft, which has just been placed into orbit around Vesta. In the first four parts of this dissertation we investigate the origin of olivine in diogenites, which are ultramafic cumulates from Vesta. We discover that the majority of these samples are dimict (two-component) breccias, composed of harzburgitic and orthopyroxenitic lithologies. This is contrary to the traditional belief that all diogenites are orthopyroxenites with small amounts of cumulus olivine. Using bulk and in situ trace element chemistries, along with mineral major/minor element compositions, we demonstrate that these two lithologies were likely related through fractional crystallization. We also examine an anomalous achondritic dunite, and use geochemistry and petrology to demonstrate that it is the first recognized dunite belonging to the HED group. This sample likely also fractionated from a melt prior to the fractionation of harzburgitic and orthopyroxenitic diogenites. In the final part of this dissertation, we investigate compositional and textural heterogeneity in a large group of paired howardites, Vestan regolith breccias composed of diogenite and eucrite. We find significant compositional and textural variation within the group, and a preferential distribution of eucritic material in the finer grain sizes. This suggests an immature regolith, and has implications for interpretation of spectral data to be collected by the Dawn orbiter at Vesta.

The diamondback moth, Plutella xylostella (Linnaeus 1758.) (Lepidoptera: Plutellidae), is a major insect pest of Brassica crops in many parts of the world leading to economic losses amounting to an estimated US$ 4-5 billion. Although parasitoids (biological control agents) play a major role in suppressing the pest populations during November – May in South Africa, the pest reaches outbreak status during September and October due to low impact of parasitoids, which has necessitated regular application of insecticides. However, insecticide applications have often resulted in the pest developing resistance, and when coupled with the negative effects of several insecticides on parasitoids, integration of the two pest control strategies for effective management of P. xylostella population density has been difficult to achieve. One approach that has received little attention is integration of host plant resistance (bottom-up effect) and biological control (top-down effect) for effective management of P. xylostella. However, the interaction between host plants, the insect pest, and parasitoids is not simple and straight forward, as strong negative impact of host plants on fitness of the insect pest can be cascaded up the food chain and have a negative impact on a given parasitoid, which in turn may reduce the desired complementary effect between the two pest control strategies. To identify optimal interactions between cabbage (Brassica oleracea L. var. capitata, Brassicaceae), P. xylostella and its larval parasitoid Cotesia vestalis (Haliday 1834) (Hymenoptera: Braconidae), this study investigated (i) the effects of seven cabbage cultivars (Empowa, Hollywood F1, Megaton, Leano, Menzania, Beverley Hills and Karabo) on fitness parameters (survival, developmental time, pupal weights, longevity without food and oviposition rates) of P. xylostella; (ii) the influence of the same host plant cultivars on fitness parameters (developmental time, pupal weights, longevity xi without food, fecundity, emergence rate and sex ratio) of C. vestalis. Furthermore, net reproductive rates and the intrinsic rates of natural increase were calculated for C. vestalis that emerged from hosts fed on each of the cultivars. All experiments were conducted in climate-controlled laboratory rooms maintained at 22 ± 1 ºC (mean ± S.D.), 60 ± 5 % RH and 16L: 8D photoperiod. Under the no choice test, overall survival of P. xylostella immature stages was highest on Karabo (67.26%) and lowest on Megaton (44.92%). The larval and pupal developmental period, and generation time was prolonged on Empowa (18.48 days), Karabo (14.64 days) and Beverly Hills (17.48 days), while developmental period on Hollywood F1 (13.79 days) was shortest. Male and female P. xylostella pupal weights were lighter from larvae that fed on Megaton (4.13 and 4.65 mg), Menzania (4.53 and 4.91 mg), and Hollywood F1 (4.11 and 5.08 mg), whereas pupal weights from Karabo (6.0 and 6.82 mg) were the heaviest. Unfed female moths originally reared on Beverley Hills had the highest longevity (5.05 days), whereas those reared on Leano (3.54 days) and Megaton (3.89 days) had the shortest life span. Under the choice-test, P. xylostella moth laid significantly more eggs on Empowa (48.8%) and Hollywood F1 (45.6%) and least on Menzania (11.8%) and Leano (10.6%). Megaton was more resistant to P. xylostella due to lower survival rates of immature stages, lower pupal weights and moth longevity. The generation time of C. vestalis was shortest on Karabo (10.10 days) and Leano (10.38 days), and longest on Megaton (12.57 days) and Empowa (12.80 days). The highest pupal weight of C. vestalis was obtained from parasitoids reared from P. xylostella fed Menzania (5.4 mg), Megaton (5.25 mg) and Beverly Hills (4.85 mg) and the lightest on Karabo (3.8 mg). Parasitoids reared on larvae that fed on Hollywood F1 lived the longest (2.28 days) followed by Menzania (1.94 days) and Beverly Hills (1.8 days), whereas those whose hosts fed on Leano had shortest life span (0.83 days). Despite the parasitoids from Megaton hosts being heavier, their fecundity and number of female progeny per female (16.87 and 3.60, respectively) were lowest. Cotesia vestalis fecundity and daughters produced per female were highest on hosts fed on Menzania (38.00 and 9.13, respectively) and Beverly Hills (32.87 and 9.07, respectively). As a consequence, the net reproductive rate (R0) and intrinsic rate of increase (r) were higher on Menzania (7.87 and 0.58, respectively) and Beverly Hills (8.29 and 0.62, respectively). As survival and overall fitness of P. xylostella was lower on Megaton, this cultivar can play a major role in restricting population growth of this pest and thus generational number of eggs deposited on it during September and October. However, this strong bottom-up effect of Megaton on P. xylostella was cascaded up the food chain, as overall fitness of C. vestalis was lower on hosts developing on it. In contrast, the overall fitness of C. vestalis was higher on hosts that developed on Menzania and Beverly Hills. As these cultivars showed potential to sustain population density of C. vestalis at higher levels, it is also assumed that the period required for the parasitoid to reach the critical density to suppress the host population at a lower average density will be reached quicker than on other cultivars. Thus, their cultivation may improve biological control of P. xylostella during November–May in South Africa

La ricerca è orientata alla ricostruzione di vari aspetti del multiforme rapporto che intercorse tra alcuni esponenti della famiglia Ruiz –mercanti di tele all’ingrosso– i tessuti e i vestiti, nell’effervescente contesto dell’Impero asburgico durante l’ultimo terzo del XVI secolo, tra Medina del Campo (città delle fiere) e Valladolid (capitale dell’area), attraverso lo studio del celebre archivio di questa famiglia.Il rapporto tra i Ruiz (grossisti di tele) e il binomio tessuti-vestiti è stato analizzato in una cornice ampia e attraverso varie scale di osservazione: anzitutto la “famiglia di mercanti” (integrando la bibliografia con documenti inediti) e successivamente con una serie di ricerche proiettate verso la “famiglia di clienti” – sia sul lungo periodo, sia isolando momenti precisi, tra le singole biografie e il quotidiano, tra le compravendite per affari e lo shopping di tele e vestiti, e comparando, infine, la “rete Ruiz” ad altre 25 famiglie di Medina e Valladolid.Il primo capitolo presenta brevemente lo stato dell’arte, le fonti e la metodologia (conti, inventari, testamenti e “diversi”, raccolti con un database); il secondo il Regno di Castiglia nel XVI secolo (economia e società) e la figura del mercante arricchito; il terzo la storia della famiglia Ruiz (le due generazioni centrali, un approfondimento su Simon e un altro sull’Ospedale Generale che egli fondò).Il capitolo 4 affronta le tele e i tessuti, esamina alcuni affari all’ingrosso e al dettaglio (in cui si apprezzano molteplici comportamenti dei Ruiz), e analizza approfonditamente le oltre 275 occorrenze di tessuti rinvenute nella documentazione.Dopo il capitolo 5, un’approssimazione bibliografica alla moda cinquecentesca e a una trentina di capi d’abbigliamento del tempo, sono presentati, nel capitolo 6, il rapporto tra i Ruiz, il sarto e il vestito, le modalità “alternative” di acquisizione di vestiti e alcuni esempi di acquisto di copricapi, guanti, calzoni e calzature.Il capitolo 7 è centrato sulla comparazione degli inventari dei Ruiz con quelli di altre famiglie castigliane della seconda metà del XVI secolo: si presenta brevemente la “ricchezza materiale” dei 33 soggetti analizzati, si definiscono le macrocategorie in cui il patrimonio studiato è stato suddiviso (“apparenza cavalleresca”, “apparenza indossata”, “apparenza domestica”, “lavori domestici”, “fonti dell’apparenza”, “libri”) per un totale di oltre 13.500 entrate corrispondenti a oltre 33.000 voci, e, infine, si affronta con un maggior grado di dettaglio l’abbigliamento (oltre 3.100 entrate –corrispondenti a quasi 5.000 voci–, la seconda macrocategoria dopo l’“apparenza domestica”; la macrocategoria è stata suddivisa negli insiemi “vestito”, “copricapi”, “accessori”, “complementi”, “calzature” e “gioielli”).Si è potuto immaginare un guardaroba comune alla totalità dei soggetti analizzati, con le voci più ricorrenti e i capi d’abbigliamento più diffusi. I Ruiz e i cugini Presa si attestano tra i maggiori possessori non solo di vestiti in generale, ma anche di singoli capi, sia in termini relativi sia assoluti.Non solo emerge la tendenza al “vivir noblemente”, bensì è riscontrabile, anzitutto per quanto concerne i vestiti, un “eccezionale stile di vita nobile”.Se è possibile intuire, con una osservazione condotta “dall’alto” (ovvero dai numeri estratti dagli inventari), una moda, dei modelli di consumo e delle tendenze generali e condivise, è parallelamente necessario sottolineare come, scorrendo le singole voci dei documenti concreti, la varietà sia una delle costanti (varietà di documenti e mani, di tele –e “famiglie” e “tipologie” di tele–, di mode). Più che cambiamenti di fogge o di abiti, che pure ci furono (e che sono stati ravvisati), si avverte una vorticosa varietà di tessuti e tecniche, di decorazioni e ornamenti.Riassumendo in una frase il percorso tra soggetti, tessuti e vestiti: i Ruiz, una famiglia di mercanti di lana vestiti di seta.
The research is aimed at the reconstruction of various aspects of the multiform relationship which took place between certain exponents of the Ruiz family –wholesale merchants of fabric– the textiles and the clothes, in the effervescent context of the heart of the Hapsburg Empire during the last third of the 16th century, in Medina del Campo (the town of the fairs) and Valladolid (the capital of the area), through the study of the familiar archive.The relationship between the Ruiz family (textile wholesalers) and the combination of fabric and cloth was analysed in a large context and through various scales of observation: firstly with the "family of merchants" (integrating the bibliography with inedited documents), and subsequently with a series of researches projected towards the "family of clients" – both in the long run as well as in precisely isolated moments, between single biographies and the everyday life , from business transactions and the shopping for fabric and clothes, and finally comparing the "Ruiz network" and other 25 families.The first chapter briefly presents the ample state of the art, the sources and the methodology (accounts, inventories, testaments, “diverse”, mainly gathered with a database); the second the Kingdom of Castilla in the 1500s (economy and society) and the figure of the wealthy merchant; the third the story of the Ruiz family (the two central generations, Simon and the Hospital General of Medina he founded.Chapter 4 deals with the textiles and the fabrics, examining certain wholesale transactions and other retail transactions (in which we can appreciate the multiple agency of the Ruiz family), and deeply analyses over 275 occurrences of fabric found in the documents. After chapter 5, which contains a bibliographic approximation of the fashion of the 1500s and the clothing worn at that time (about 30 examples of articles of clothing), chapter 6 presents the relationship between the Ruiz family, the tailor and the clothing, the "alternative" modalities for the acquisition of clothes, and certain examples of the acquisition of head coverings, gloves, trousers and shoes. Chapter 7 focuses on the comparison of the inventories of the Ruiz family with those of other Castilian families in the second half of the 16 th century. The "material wealth" of 33 subjects is examined, and the macrocategories in which the patrimony studied has been subdivided are defined ("knightly appearance", "worn appearance", "domestic appearance", "domestic work", "sources of appearance", "books") for over 13.500 entries, corresponding to over 33.000 items. Finally, the clothing is examined in further detail (over 3.100 entries corresponding to almost 5.000 items, the second macrocategory after the "domestic appearance").It was possible to imagine a wardrobe which was common to the totality of the subjects analysed, with the most recurring items and the clothes which were most diffused.The Ruiz family and the Presa family were amongst the major owners not only of clothes in general, but also of single pieces, in absolute and relative term. Not only there emerges the tendency to "vivir noblemente", but also it is noticeable, also for the clothing, an "exceptional noble lifestyle".If it is possible to realize, with an observation conducted "from above" (that is, from the numbers extracted from the inventories), a fashion, some patterns of consumption, and some general shared tendencies, at the same time it is necessary to emphasize how, going through the single items of the concrete documents, that variety is one of the constants (a variety of documents and hands, fabrics –both “families” and “tipologies”–, fashions).More than the changes of forms or clothes, which did take place (and which have been recognized) a spinning variety of fabrics and techniques, of decorations and ornaments.Summarizing in one phrase the trajectory of the subjects, fabrics and clothing: the Ruiz, a family of wool merchants dressed in silk.
