Abstract:
Thermal oxide films on SiC epitaxial (000-1) C-faces have been characterized by angle-resolved photoemission spectroscopy (AR-PES). The structure of wet oxide/SiC C-face interface was compared with that of dry oxide/SiC C-face, as well as that of dry oxide/SiC Si-face, in order to clarify why a MOS device of SiC C-face achieved good electrical properties. The improvement in electrical properties was confirmed by AR-PES measurements, evidencing differences in binding energy between SiC and the Si4+ components in Si2p and valence band region, and in binding energy between SiC and the CHx components in C1s. The reason for the improvement in electrical property of MOS devices by use of SiC C-face are discussed in terms of depth profiles of oxide films calculated from the AR-PES results.

Abstract:
Phenolic resin was used as the raw material, formed a mold for complex-shaped component by rapid-prototyping. It was composed of SiC, C and Si. The sample hardness was analyzed through statistical comparison. The phase composition of C/SiC composite was investigated by XRD and microstructures of C/SiC ceramic components were observed with scaning electron microscope. The ceramic components obtained at 1500 by reactive infiltration of Si into porous C-template. The porous structure formed by photecurable resin and starch powders pyrolysis could effectively prevent the C-template from cracking and reduce the stress. It also facilitate penetrating Si to the C-template to form SiC.

Abstract:
The process of Electron Beam-Physical Vapor Deposition (EB-PVD) preparing SiC coating with liquid evaporation was firstly discussed from a thermodynamic viewpoint. The results showed that the ratio of SiC in the as-deposited coating gradually increases and tends to reach a stable maximum of 0.73 with the evaporation temperature increase from 2500 K to 3400 K. To verify the thermodynamic analysis, amorphous SiC coating was deposited on Si substrate by EB-PVD at 3100 K. SiC concentration across the cross section of coating was calculated from the area of elements spectrum in X-ray photoelectron spectroscopy (XPS) depth profile analysis. The results showed that the average SiC concentration was about 0.7.

Abstract:
The texture development was investigated in the extruded Al and Al metal matrix composites (MMCs) reinforced with SiC particles of different sizes and volume fractions. During extrusion, both the unreinforced Al and the MMCs develop a strong fiber texture with two components: <111> and <100>. When SiC is introduced into aluminum, the main component of texture is not modified, but the intensity of the component evolves with the volume fraction and average size of SiC particles. For the MMCs reinforced with 3.5μm SiC particles, the texture intensity of the Al matrix tends to decrease as the SiC volume fraction increases, and it is lower than that in the unreinforced Al. However, for the MMCs reinforced with 25 nm and 150 nm SiC particles, the texture intensity of the Al matrix is higher than that in the unreinforced matrix, and it increases with increasing the SiC volume fraction. It is found that superfine particles may introduce some new component into the deformation texture, and the texture intensity increases as the SiC particle size decreases.

Abstract:
AbstractPurpose: Cortical and subcortical functional activity stimulated via saccade and vergence eye movements were investigated to examine the similarities and differences between networks and regions of interest (ROIs). Methods: Blood oxygenation level-dependent (BOLD) signals from stimulus-induced functional Magnetic Resonance Imaging (MRI) experiments were analyzed studying 16 healthy subjects. Six types of oculomotor experiments were conducted using a block design to study both saccade and vergence circuits. The experiments included a simple eye movement task and a more cognitively demanding prediction task. A hierarchical independent component analysis (ICA) process began by analyzing individual subject data sets with spatial ICA to extract spatial independent components (sIC), which resulted in three ROIs. Using the time series from each of the three ROIs per subject, per oculomotor experiment, a temporal ICA was used to compute individual temporal independent components (tICs). For each of the three ROIs, the individual tICs from multiple subjects were entered into a second temporal ICA to compute group-level tICs for comparison. Results: Two independent spatial maps were observed for each subject (one sIC showing activity in the frontoparietal regions and another sIC in the cerebellum) during the six oculomotor tasks. Analysis of group-level tICs revealed an increased latency in the cerebellar region when compared to the frontoparietal region. Conclusion: Shared neuronal behavior has been reported in the frontal and parietal lobes, which may in part explain the segregation of frontoparietal functional activity into one sIC. The cerebellum uses multiple time scales for motor learning. This may result in an increased latency observed in the BOLD signal of the cerebellar group-level tIC when compared to the frontal and parietal group-level tICs. The increased latency offers a possible explanation to why ICA dissects the cerebellar activity into an sIC. The hierarchical ICA process used to calculate group-level tICs can yield insight into functional connectivity within complex neural networks.

Abstract:
La volonté de diminuer la consommation en carburant en aéronautique amène à repenser les architectures de distribution et de conversion de puissance embarquées. L’utilisation d’un outil d’optimisation déterministe apparait comme une solution prometteuse pour prendre en compte les compromis intrinsèques aux convertisseurs statiques en pré-dimensionnement, avec pour objectif de minimiser leur masse. Un outil d’optimisation est donc proposé pour apporter des éléments de comparaison entre différentes topologies d’onduleur et entre différentes solutions technologiques.Le développement de l’outil passe par l’élaboration de modèles analytiques pour être compatible avec l’utilisation d’un algorithme à base de gradients. Une analyse harmonique reposant sur des transformées de Fourier permet de reconstituer les ondulations de chaque signal, en regard des normes aéronautiques. La modélisation s’intéresse également à la construction de modèles pour les composants passifs et actifs, permettant en particulier d’évaluer les pertes et donc le rendement du convertisseur. L’intégralité des modèles développés fait l’objet d’une validation expérimentale sur un prototype à 10 kW.L’utilisation d’un algorithme à base de gradient n’étant pas classique en électronique de puissance, des études sont menées pour valider la méthodologie proposée. Ces études montrent l’adéquation du choix d’un tel algorithme avec le besoin de pré-dimensionnement, tout en indiquant ses limites et les perspectives. Enfin, l’outil d’optimisation est utilisé pour comparer différentes solutions architecturales et technologiques sur des cas d’application aéronautiques. Les résultats obtenus sont discutés en regard des méthodes de dimensionnement classiques
The exponential development of aircraft transportation is a threat in the context of global warming. One of the solutions investigated consists in increasing the amount of embedded electrical power systems and actuators. Using a deterministic optimization tool appear as a promising solution to take into account the multiple compromises in a power converter design during the pre-design step, with the goal to minimize the weight. An optimization tool is proposed to bring comparative elements between different inverter topologies and technological solutions.The development of the tool requires elaborating analytical models to be compliant with the gradient-based algorithm. Harmonic analyses with Fourier transform enable calculating the signal ripples, to respect aircraft standards. Components are also designed precisely with appropriate loss models to estimate the converter efficiency. All the developed models are experimentally validated with a 10 kW prototype.As the use a gradient-based algorithm is not common in power electronics, studies are carried out to validate this proposed methodology. These studies show the effectiveness of the algorithm choice in the pre-design step, and indicates some limits and forecasts. Finally, the algorithm is used to compare different architectural and technological solutions on aircraft cases. The results are discussed regarding classical sizing methodologies

Abstract:
Depuis le début des années 2000, les composants en carbure de silicium (SiC) sont présents sur le marché principalement sous la forme de diodes Schottky et de transistors FET. Ces nouveaux semi-conducteurs offrent des performances en commutation bien supérieures à celles des composants en silicium (Si) ce qui se traduit par une diminution des pertes et une réduction de la température de fonctionnement à système de refroidissement identique. L’utilisation de composants SiC ouvre donc la possibilité de concevoir des convertisseurs plus compacts ou à une fréquence de commutation élevée pour une même compacité. C’est avec cet objectif d’augmentation de la fréquence de commutation qu’a été menée cette étude axée sur l’utilisation de composants SiC au sein d’un onduleur triphasé. Le convertisseur sur lequel se base l’étude accepte une tension d’entrée de 450V et fournit en régime nominal un courant de sortie efficace par phase de 40 A. Le choix des composants SiC s’est porté sur des transistors JFET Normally-Off et des diodes Schottky SiC car ces composants étaient disponibles à la vente au début de ces travaux et offrent des pertes en commutation et en conduction inférieures aux autres structures en SiC. Les transistors FET possèdent une structure et des propriétés bien différentes des IGBT habituellement utilisés pour des convertisseurs de la gamme considérée notamment par leur capacité à conduire un courant inverse avec ou sans diode externe. De ce fait, il est nécessaire de développer de nouveaux outils d’aide au dimensionnement dédiés à ces composants SiC. Ces outils de calculs sont basés principalement sur les paramètres électriques et thermiques du système et sur les caractéristiques des composants SiC. Les premiers résultats montrent qu’en autorisant la conduction d’un courant inverse au sein des transistors, il est possible de diminuer le nombre de composants. Basées sur ces estimations, une maquette de bras d’onduleur a été développée et testée. Les premiers thermiques montrent que pour une puissance de 12kW, il est possible d’augmenter la fréquence de commutation de 12 kHz à 100 kHz
Since 2000, Silicon Carbide (SiC) components are available on the market mainly as Schottky diodes and FET transistor. These new devices provide better switching performance than Silicon (Si) components that leads to a reduction of losses and operating temperatures at equivalent cooling system. Using SiC components allows to a better converter integration. It is in this context that ECA-EN has started this thesis dedicated to using SiC devices in a three-phase inverter at high switching frequency. The converter object of this study is supply by a input voltage of 450V and provides a current of 40A per phase. The components used for these study are SiC Normally-Off JFET and Schottky Diodes because these devices were commercialized at the begining of this thesis and offer better switching performance than others SiC components. FET transistors have a different structure compared to traditionnal IGBT especially their capability to conduct a reverse current with or without body diode. So it is necessary to develop new tools dedicated to the design of converters built with SiC components. These tools are based on the electrical properties of the converters and the statics and dynamics characteristics of the transistor and the diode. The results show that when the transistors conduct a reverse current, the number of components/dies can be reduced. According to data, a PCB board of an inverter leg has been built and tested at ECA-EN. The thermal measurement based on the heatsink shows that the switching frequency of an inverter leg can be increased from 12 to 100 kHz for an ouput power of 12kW

Avec le développement des nouveaux composants de puissance à grand gap plus performants que leurs homologues en Silicium et l’intégration croissante de ces composants dans le véhicule électrique, la compatibilité électromagnétique est devenue un enjeu important pour le respect des normes de conformité en vigueur. La thèse traite donc les méthodes de modélisation haute fréquence des composants grand gap. Les problèmes liés à la fiabilité et la précision des modèles actuels sont mis en évidence. Ensuite, un nouveau modèle générique est proposé avec des formulations spécifiques lui permettant de mieux reproduire les caractéristiques statiques et dynamiques des MOSFETs en SiC. Des bancs de test ont été mis en place permettant de caractériser ces nouveaux composants avec des précautions spécifiques afin d’améliorer la précision de ces mesures. L’utilisation d’un algorithme génétique développé pour identifier les paramètres du modèle générique proposé, a permis une reproduction fine des caractéristiques mesurées expérimentalement de plusieurs composants SiC ainsi que les perturbations CEM générées dans un convertisseur statique
With the development of new large-gap power components with superior performance compared to their Silicon counterparts and the rising integration of these components in the electric vehicle, electromagnetic compatibility has become an important issue for compliance with normative standards. Hence, this thesis discusses the modeling methods of wide bandgap components. Problems related to the reliability of the models and their accuracy are highlighted. Then, a new model is proposed with specific formulations allowing it to better reproduce the static and dynamic characteristics of SiC MOSFETs. Test benches have been set up to characterize these new components with specific precautions in order to improve the precision of the measurements. The use of a developed genetic algorithm to identify the parameters of the proposed generic model, allowed a close reproduction of the characteristics measured experimentally of several SiC components as well as the EMC disturbances generated in a static converter

Abstract:
Actuellement, le développement de semiconducteurs et la demande croissante de convertisseurs en électronique de puissance dans les différents domaines de l’énergie électrique, notamment pour des applications dans l’aéronautique et les réseaux de transport et de distribution, imposent de nouvelles spécifications comme le fonctionnement à hautes fréquences de commutation, densités de puissance élevées, hautes températures et hauts rendements. Tout ceci contribue au fort développement des composants en SiC (Carbure de Silicium). Cependant, ces composants créent de nouvelles contraintes en Compatibilité Electromagnétique (CEM) à cause des conditions de haute fréquence de commutation et fortes vitesses de commutation (forts di/dt et dv/dt) en comparaison à d’autres composants conventionnels de l'électronique de puissance. Une étude des perturbations générées par les composants SiC est donc nécessaire. L'objectif de ce travail est de donner aux ingénieurs amenés à concevoir des convertisseurs une méthode capable de prédire les niveaux d'émissions conduites générées par un convertisseur électronique de puissance qui intègre des composants en SiC. La nouveauté du travail présenté dans cette thèse est l’intégration de différents modèles de type circuit pour tous les constituants d’un convertisseur (un hacheur série est pris comme exemple). Le modèle est valable pour une gamme de fréquences de 40Hz à 30MHz. Des approches de modélisation des parties passives du convertisseur sont présentées. Ces approches sont différentes selon que les composants modélisés soient disponibles ou à concevoir : elles sont basées sur des mesures pour la charge et les capacités ; elles sont basées sur des simulations prédictives pour routage du convertisseur. Le modèle complet du convertisseur (éléments passifs et actifs) est utilisé en simulation pour prédire les émissions conduites reçues dans le réseau stabilisateur d’impédance de ligne. Le modèle est capable de prédire l'impact de différents paramètres comme le routage, les paramètres de contrôle comme les différents rapports cycliques et les résistances de grille avec des résultats satisfaisants dans les domaines temporels et fréquentiels. Les résultats obtenus montrent que le modèle peut prédire les perturbations en mode conduit pour les différents cas jusqu'à une fréquence de 15MHz. Finalement, une étude paramétrique du convertisseur a été élaborée. Cette étude a permis de voir l’influence de la qualité des différents modèles comme les éléments parasites du routage, des composants passifs et actifs et d'identifier les éléments qui ont besoin d’un modèle précis pour avoir des résultats valides dans la prédiction des perturbations conduites
The recent technological progress of semiconductors and increasing demand for power electronic converters in the different domains of electric energy particularly for applications in aeronautics and networks of transport and distribution impose new specifications such as high frequencies, high voltages, high temperatures and high current densities. All of this contributes in the strong development of SiC (Silicon Carbide) components. However these components create new issues in Electromagnetic Compatibility (EMC) because of the conditions of high frequency switching and high commutation speeds (high di/dt and dv/dt) compared to other conventional components in power electronics. A precise study of the emissions generated by SiC components is therefore necessary. The aim of this work is to give a method able to predict levels of conducted emissions generated by a power electronics converter with SiC components to engineers which design power converters. The novelty of the work presented in this thesis is the integration of different modeling approaches to form a circuit model of a SiC-based converter (a buck dc–dc converter is considered as an example). The modeling approach is validated in the frequency range from 40Hz to 30MHz. Modeling approaches of the passive parts of the converter are presented. Theses approaches differs according to whether the component is existing or to be designed : they are based on measurements for the load and capacitors; they are based on numerical computation and analytical formulations for PCB. The complete model obtained (passive and active components) is used in simulations to predict the conducted emissions received by the line impedance stabilization network. The model is able to predict the impact of various parameters such as PCB routing, the control parameters like duty cycles and different gate resistors in the time and frequency domains. A good agreement is obtained in all cases up to a frequency of 15MHz. Finally, a parametric study of the converter has been elaborated. This study allowed to see the influence of different models such as parasitic elements of the PCB, passive and active components and to identify the elements that need a precise model to obtain valid results in the prediction of conducted EMI

Abstract:
La membrane bactérienne a fait l'objet de nombreuses études de localisation de protéines et de phospholipides. Par fusion d’une protéine fluorescente (GFP) aux gènes d’intérêt, il est alors possible d‘observer la localisation des protéines associées par microscopie. La plupart de ces observations ont été réalisées à l’aide de microscopes dits à épifluorescence. Afin d’obtenir une qualité d’image suffisante, il était nécessaire de surexprimer la protéine observée, insérée à un locus ectopique non naturel. Ce travail de thèse a permis d’utiliser une nouvelle technologie acquise dans notre laboratoire, le microscope à fluorescence par réflexion totale interne (TIRFM), plus puissant que le microscope à épifluorescence utilisé précédemment. Cette technologie a permis une caractérisation plus détaillée de la localisation de protéines d’intérêt, placées sous contrôle de leur promoteur naturel. Il a également été possible de caractériser la dynamique des foci observés. Nous avons concentré notre étude sur 3 protéines: (i) SecA pour l’étude de la translocation des protéines du cytoplasme vers la membrane, (ii) YidC pour l’insertion des protéines dans la membrane, (iii) PgsA pour la synthèse des phospholipids. Les foci se déplacent dynamiquement et s’associent de manière transitoire dans la membrane. L’observation sur la durée de ces foci, et l’analyse de leur intensité moyenne au cours des observations, montre que SecA se déplace sur l’ensemble de la membrane de manière uniforme. L’analyse du déplacement des foci montre une relation quadratique entre la distance moyenne parcourue par les foci en fonction du temps. Ce résultat est en accord avec l’hypothèse d’un mouvement brownien des foci. Les foci sont observés dans les différentes phases de croissance des cellules, et le nombre de foci présents dans une cellule de la longueur de celle-ci. SecA-GFP a été testés dans un certain nombre de contextes génétiques. La localisation a été perturbée lors de la déplétion de pgsA. Cependant, comme PgsA est une protéine essentielle, il ne peut être exclu que ce changement de localisation apparaît des cellules qui sont mortes ou mourantes. Dans une souche mutante ΔclsA, on n’observe aucune différence dans la localisation de SecA en phase exponentielle, mais on aperçoit une relocalisation aux poles en phase stationnaire de croissance. La voie Tat est responsable du transport des protéines devant être exportées dans un état structuré, par exemple dans le cas de l’incorporation d’un co-facteur. À ce jour, la régulation du système Tat est peu connues, de même que les interactions entre les différentes sous-unités du système Tat et d'autres protéines dans le cytoplasme, dans la membrane ou dans la paroi cellulaire. Des fusions de les gènes de la voie Tat ont été co-exprimées deux à deux dans des cellules de levure, et leur capacité à interagir in vivo a été testée par la méthode dite du double hybride chez la levure. Nous avons généré un réseau d’interaction autour des cinq composants de système Tat. Pour déterminer les implications fonctionnelles des composants du réseau, nous avons travaillé en collaboration avec le laboratoire de Jan-Maarten van Dijl. Nous avons utilisé une collection de souches mutantes pour lesquels certains composants individuels du réseau ont été retires. Trois a été observe d’etre nécessaires pour la sécrétion Tat-dépendante. Nous avons étudié la localisation des fusions GFP avec ces proteins. On a observé une localisation double de HemAT selon l’état physiologique de la cellule. En phase exponentielle, les cellules de B. subtilis sont généralement présentes sous forme de chaînes dans lesquelles le septum de division a déjà été formé, mais la séparation cellulaire n'a pas encore eu lieu. Une fusion de la GFP à CsbC apparaît de façon homogène dans la membrane
In the years since the cloning of GFP, the field of bacterial cell biology has characterized a variety of specific protein localization patterns in the bacterial membrane. The vast majority of early subcellular localization studies made use of inducible GFP fusions, which generally required the presence of high concentrations of inducer, and can therefore be considered to be overexpressed. An outstanding question remains over the organization of natively expressed proteins in the membrane. Here, we have investigated the localization of functional GFP fusions to proteins catalyzing important membrane processes; the secretion motor protein SecA, the membrane insertase YidC1, and the essential phospholipid synthase PgsA using total internal reflection fluorescence microscopy (TIRFM). This allowed natively expressed proteins to be localized with temporal resolution that can capture their dynamics. We characterized dynamic complexes dispersed throughout the membrane displaying diffusive movement with no preferred trajectories. Further characterization focused upon identifying conditions in which the localization pattern was disturbed. A polar mislocalization was identified in a cardiolipin mutant strain. The yeast two-hybrid (Y2H) approach is a robust approach to detect binary interactions on a proteome-scale. We performed genome-wide Y2H screens as well as targeted Y2H analyses for specific interactions involving components of the Sec and Tat secretion machineries of B. subtilis, revealing an intricate protein-protein interaction network involving 71 proteins. Furthermore, three proteins identified in the Tat network, WprA, CsbC and HemAT, were shown to be important for effective protein secretion via the B. subtilis Tat system, indicating that our yeast two hybrid assays reveal biologically significant interactions involving membrane proteins. The studies provide a novel proteomic view on the interaction network of the secretion systems of B. subtilis

Over time the Physical Education on IFRN has considered the sport as the only possibility of pedagogical action. In the purpose of investigating the aspects that determine this condition, this study aimed the context of physical education within the institutional framework and its current perspectives in the process of institutional transformation. In this sense, were addressed the following study questions: What political pedagogical aspects that influenced the context of Physical Education on IFRN and how the pedagogical experience on Mossoro s campus incorporated the perspectives of curricular proposals transformation for the High School and the theoretical changes of the Brazilian Physical Education. Methodologically the work was based on a qualitative approach characterized as a descriptive- comparative research. The technique of discourse analysis was employed in the speech of research collaborators having as categories of analysis the professional activities time in the institution; The ratio of official use of the assumptions to the pedagogical practice of Physical Education in IFRN; The sport in the education process of students and The Prospects of Physical Education in the current configuration of IFRN. The data analysis allowed us to infer that the theoretical methodology of pedagogical practice of Physical Education in IFRN need to be reformulated and that it is necessary a contextualization with the curricular principles of the political institutional pedagogical project and with the Curriculum Guidelines for Secondary Education. The teaching experience developed in the Mossoro s Campus was contextualized with the national curriculum guidelines for secondary education and the theoretical changes of the Brazilian Physical Education. We conclude that it is necessary a collective action of the group of teachers to transform the educational profile of Physical Education of IFRN, beyond the institutional support to be able to consolidate the physical education curriculum component in the current dimensions of society, human being, education, science, technology and work, proposed by the philosophical principles and epistemological political project of IFRN educational

Abstract:
Il volume, attingendo a tradizioni disciplinari e storiografiche diverse, offre una serie di sintesi e di affondi tematici, funzionali alla contestualizzazione del peculiare caso dell’episcopato di Bobbio, fondato nel 1014 nell’Appennino piacentino quale sviluppo del celebre monastero di San Colombano. La notevole massa documentaria disponibile grazie al recente riordino degli archivi diocesani, che ha consentito di illustrare anche la biblioteca della cattedrale, ha richiesto una presentazione d’insieme e una specifica attenzione per gli atti costitutivi della nuova istituzione. L’approfondimento del contesto storico entro cui si dipana la successiva vicenda diocesana è stato condotto in rapporto con il monastero e con una selezione delle città vicine. All’analisi delle dinamiche insediative del centro bobbiese e degli sviluppi strutturali della chiesa e del complesso episcopale fanno da contrappunto sia approfondimenti mirati all’organizzazione del territorio, colta nelle sue articolazioni civili, religiose, assistenziali, sia trattazioni di componenti culturali e liturgiche che animano questa Chiesa.

Abstract:
La ricerca nel campo dell'epigrafia si arricchisce continuamente con la scoperta di documenti inediti e vive oggi un radicale rinnovamento grazie alle tecnologie digitali. Una componente fondamentale del «mestiere di epigrafista» è però costituita anche dalla ricostruzione filologica e dall'indagine delle figure che si cimentarono nella collazione dei testimoni delle iscrizioni antiche. Il volume comprende sedici saggi di studiosi italiani e francesi, dedicati all'esame della tradizione manoscritta e a stampa dell'epigrafia, che Theodor Mommsen definì la «parte più difficile» della disciplina. Dai tesori ancora nascosti in numerose biblioteche d'Europa emerge un quadro di grande ricchezza documentaria, che presagisce un enorme potenziale di sviluppo per la ricerca futura.

Abstract:
Una Sardegna riservata e lontana anima i testi di questo doppio carteggio, tra paesaggi arcaici e mitologie personali e letterarie nelle quali si inserisce ogni tanto la Ferrara degli anni giovanili degli autori, ricca di vita, di riviste («Primato» di Bottai, il «Corriere Padano» con la presenza di Bassani…), incontri serali nelle osterie o nelle camere in affitto, passeggiate lungo i Rampari, e l’uso di scherzosi soprannomi che sarebbe continuato oltre la giovinezza. Un mondo fatto di cose concrete, animato e vivificato da forti curiosità e passioni intellettuali, emerge dalle lettere, accuratamente trascritte e annotate da Costanza Chimirri, che ricostruiscono la vita e la storia di Giuseppe Dessí, Mario Pinna, Claudio Varese. La corrispondenza si apre con gli anni trascorsi a Ferrara – dopo Pisa momento cruciale per la loro formazione – e consente di ricostruire atmosfere ed ambienti, letture e lavoro, offrendo dall’interno un significativo spaccato dell’Italia del Novecento. Mai slegati tra loro, bensì uniti dal continuo richiamo alla triplice amicizia nel nome di Giuseppe Dessí, che è sempre presente, anche in assenza, nei discorsi degli altri, i carteggi hanno consentito anche di riportare alle luce testi inediti del più appartato del gruppo (Mario Pinna, accanito lettore di classici, ispanista, autore di poesie in dialetto logudorese e di brevi racconti ambientati in Sardegna), di rafforzare il ruolo da sempre ricoperto dal più ‘antico’ – per tutti maître-camarade – Claudio Varese; e di confermare ancora una volta quanto l’universo creativo di Dessí, profondamente segnato dalla componente biografica, abbia continuato a svilupparsi e alimentarsi sotto lo sguardo sapiente e affettuoso di amici fraterni, in uno scambio capace di dare vita a un vero e proprio immaginario collettivo.

Abstract:
Il terzo volume di Florentia prosegue la serie periodica di studi legati alle attività di formazione della Scuola di Specializzazione in Archeologia dell’Ateneo fiorentino. Gli studi selezionati costituiscono elaborazioni tratte dalle migliori dissertazioni di diploma redatte dagli allievi negli ultimi anni, secondo criteri che privilegiano gli elementi di maggiore innovatività tematica e saldezza metodologica. I saggi rappresentano gli indirizzi fondamentali della Scuola: pre-protostorico, orientalistico, ‘classico’ (nelle sue varie componenti, greco-romana ed etrusco-italica), medievista. Gli autori provengono da Atenei di tutto il Paese: una varietà che tuttavia lascia trasparire il connotato culturale di fondo che caratterizza la Scuola archeologica fiorentina, a partire dalla lezione dei fondatori della Scuola, i non dimenticati Paolo Emilio Pecorella e Luigi Beschi, alla cui memoria questo volume è dedicato. La consuetudine fra docenti (in buona parte giovani anch’essi) ed allievi costituisce una comunità di studi che si vale di un coordinamento strutturale con le altre Scuole di Specializzazione dell’Ateneo dedicate ai Beni Culturali territoriali (Archeologia, Storia dell’Arte, Architettura); con scelte proiettate anche in una dimensione pubblica in rapporto a temi dell’attuale società civile – dall’incidenza sociale del ruolo dell’archeologo militante, all’apporto identitario di un’‘archeologia pubblica’ in una società che muta rapidamente, fra ‘nuovi italiani’ e uso sociale della cultura; al nuovo ruolo dell’archeologia (e non solo) – anche in contesti di crisi, non solo internazionali.

Abstract:
Abstract Silicon Carbide fiber-reinforced Silicon Carbide (SiC/SiC) Ceramic Matrix Composites (CMCs) are currently operating in select high temperature components of turbine engines. Primary benefits of CMCs compared to metals are improved temperature capability, reduced cooling requirements and reduced component weight. High temperature materials require less cooling air to be diverted from the compressor, resulting in improved engine performance. However, some amount of film cooling may be necessary when CMCs are implemented in higher temperature applications. Film cooling requires holes to be fabricated at appropriate locations and orientations within these components. It is important to understand how such holes will affect the material properties. While previous studies have shown that CMCs are notch insensitive, the effect of multiple holes and different hole orientations on SiC/SiC CMCs is not well documented. This study examines the effect of cooling holes on SiC/SiC tensile properties. Several hole geometries fabricated in SiC/SiC samples are explored. Mechanical test data on specimens with multiple holes is reported for tensile loading at room temperature. Tools such as Digital Image Correlation (DIC) and Acoustic Emission (AE) are used to monitor strain and cracking in the CMC upon loading.

Abstract:
This paper presents initial results in the development and testing of SiC-based Continuous Fiber Ceramic Composites (CFCC) materials for combustor and stage 1 shroud components of large utility-class gas turbines. Use of CFCC’s for these components has the potential for increasing output power and thermal efficiency and reducing emissions. First stage turbine shroud components were fabricated using five material systems including three SiC/SiC-Si systems made by silicon melt infiltration (MI), chemical vapor infiltrated (CVI) enhanced SiC-SiC and directed metal oxidation (DIMOX) Al2O3-SiC composite. A combustor liner was made of MI CFCC. Before and after testing the components were inspected by several NDE techniques including IR thermography, resonance testing and visual examination. A novel, high pressure test rig was used to test four shroud components and a combustor liner simultaneously. Components were exposed to hot gas temperature of 1200°C at 12.5 bar in cyclic and steady-state tests. Cyclic testing simulated engine trip conditions with 200 flame-on, flame-off cycles. Steady state testing involved 100 hours of exposure at high temperature and pressure with hot combustion gases. At the conclusion of the first phase of testing there was visible damage to two pieces of one of the material systems. Destructive testing of the components following rig exposure showed little degradation to the MI composite materials. In summary, high pressure combustion rig testing of these components demonstrated excellent performance with little degradation among the material systems.

Abstract:
The successful application of ceramic matrix composites as hot-section components in advanced gas turbine engines will require the development of constituent materials and processes that can provide the material systems with the key thermostructural properties required for long-term component service. Much initial progress in identifying these materials and processes was made under the former NASA Enabling Propulsion Materials Program using stoichiometric Sylramic™ silicon-carbide (SiC) fibers, 2D-woven fiber architectures, chemically vapor-infiltrated (CVI) BN fiber coatings (interphases), and SiC-based matrices containing CVI SiC interphase over-coatings, slurry-infiltrated SiC particulate, and melt-infiltrated (MI) silicon. The objective of this paper is to discuss the property benefits of this SiC/SiC composite system for high-temperature engine components and to elaborate on further progress in SiC/SiC development made under the new NASA Ultra Efficient Engine Technology Program. This progress stems from the recent development of advanced constituent materials and manufacturing processes, including specific treatments at NASA that improve the creep, rupture, and environmental resistance of the Sylramic fiber as well as the thermal conductivity and creep resistance of the CVI SiC over-coatings. Also discussed are recent observations concerning the detrimental effects of inadvertent carbon in the fiber-BN interfacial region and the beneficial effects of certain 2D-architectures for thin-walled SiC/SiC panels.

Abstract:
Ceramic Matrix Composites (CMCs) are potentially valuable structural materials for high temperature stationary components in the hot section of advanced gas turbines. Endurance field testing, totaling in excess of 88,000 engine operating hours, conducted since 1997 by Solar Turbines Incorporated has shown promise for SiC/SiC and Oxide/Oxide CMC combustor liners. In support of ongoing development life prediction modeling was used to generate creep rupture strengths for two SiC/SiC CMC model systems, incorporating polycrystalline Hi-Nicalon and stoichiometric Sylramic-iBN fibers, respectively. The creep rupture strengths were combined with water vapor degradation modeling, extrapolated from laboratory studies, to estimate the Upper Use Temperature (UUT) of CMC combustor liners in the hot section of gas turbines of various pressure ratios. In the absence of a protective Environmental Barrier Coating (EBC) the UUT is &lt;1000°C and the advantage of the superior creep rupture strength of the Sylramic-iBN fiber over the Hi-Nicalon fiber is largely lost. The selection of a suitable EBC restores the creep rupture strength of the SiC/SiC CMCs provided the EBC remains functional during the operation of the gas turbine over the expected service life of 30,000 hours. A heat transfer study was conducted to estimate the EBC surface temperature and CMC surface and average temperatures over the Turbine Rotor Inlet Temperature (TRIT) range of 1000–1400°C. A comparison was made with a standard metal combustor liner with Thermal Barrier Coating (TBC) which can be used for TRITs up to ∼1200°C. It was learned that the SiC/SiC CMCs with the standard Si/Mullite/BSAS EBC does not offer an advantage over the metal/TBC systems at a TRIT of 1200°C because of the recession rates of the EBC constituents. Replacing the BSAS top coat with a rare earth disilicate or monosilicate has the the potential for a reduction in surface recession of the EBC by one to two orders of magnitude. It is estimated that rare earth disilicate- and monosilicate-based EBCs may enable adequate SiC/SiC CMC life for gas turbines with TRITs up to ∼1350°C and ∼1400°C, respectively.
