Abstract:

2011/2012
The doctoral thesis focuses on the output of interpreters translating the 2004 U.S. presidential debathon for Italian television (DEB.04 corpus). The contrastive qualitative analysis conducted on the corpus items aimed at identifying the infotainment elements characterising presidential debates as television genre and verifying their presence in the interpreted texts (ITs) broadcast on Italian television. More specifically, the analysis focused on discourse elements operationalising conflict (Contest-like dimension) in the question/answer group in terms of DEGREE OF CONFLICTUALITY – i.e., conflict elicitation, validation and mitigation, in both the original texts (OTs) and the ITs. The doctoral thesis was conducted within the CorIT (Italian Television Interpreting Corpus) project (Straniero Sergio & Falbo 2012) of the Department of Legal, Language, Interpreting and Translation Studies (University of Trieste). The compilation, elaboration and classification of the corpus of analysis (DEB.04) aims at providing a template for the elaboration and classification of CorIT items, using DEB.04 as a training corpus to test specific dedicated softwares.
Il presente progetto di ricerca si incentra sullo studio delle interpretazioni dei dibattiti presidenziali americani del 2004 trasmessi dalla televisione italiana (DEB.04 corpus). L’analisi contrastiva di tipo qualitativo ha avuto come obiettivo principale quello di individuare le caratteristiche del genere televisivo ‘dibattito presidenziale’ che maggiormente ne definiscono l’aspetto di ‘televisione di informazione e intrattenimento’ (infotainment television) e verificarne la presenza nel testo interpretato (TI). Nello specifico ci si è proposti di individuare gli elementi discorsuali tramite i quali l’elemento di intrattenimento (conflitto, competizione) viene operativizzato nel gruppo domanda/risposta quale cardine dell’evento comunicativo, in termini di iniziazione, mantenimento e mitigazione del grado di conflittualità dello stesso, sia a livello di testo originale (OT) che a livello di TI. La tesi dottorale si inserisce nel progetto CorIT – Corpus di Interpretazione Televisiva (Straniero Sergio & Falbo 2012) del Dipartimento di Scienze Giuridiche, del Linguaggio, dell’Interpretazione e della Traduzione, e si propone altresì di fornire una base metodologica per l’elaborazione e la catalogazione degli item di CorIT, utilizzando il corpus d’analisi, DEB.04, come training corpus per i software dedicati impiegati.

Abstract:

L’œuvre de Jean-Baptiste Camille Corot (1796-1875) a suscité, depuis le milieu du XIXe siècle, une infinité d’études et d’ouvrages analytiques et scientifiques. Pourtant, la recherche peut encore être fructueuse sur cet artiste célèbre. Cette thèse se propose donc d’aborder par l’étude topographique un corpus restreint de sa production. Le choix du site de Ville-d’Avray s’impose car, d’une part, son histoire peut être reconstituée à partir d’archives variées ; d’autre part, Corot y exécute ses premiers essais alla prima et reviendra toute sa vie travailler dans la villégiature familiale. Si ce corpus est principalement constitué de peintures et de paysages, n’en sont pas exclus les portraits, panneaux décoratifs et sujets religieux ; s’y ajoutent diverses techniques graphiques, y compris la gravure. Cette méthode inhabituelle d’appréhension d’un œuvre permet de vérifier nos connaissances (date et éventuellement historique des peintures, emplacements précis représentés). Elle donne également lieu à une interprétation très précise de la méthode de Corot (les contrées qu’il fréquente, le travail en plein air ou en atelier, le rythme de sa création, les reprises de tableaux délaissés…), et tout spécialement de l’élaboration de ses toiles dans le temps (leurs supports visuels – d’après nature, dessins, gravures ou études peintes – ou mentaux – mémoire, imagination, souvenirs) ; ainsi peut-on déduire le degré de réalisme de ses paysages. Enfin, elle apporte des indices tangibles pour authentifier les tableaux qui hantent le marché de l’art. Cette thèse se présente en deux parties : une synthèse analytique et ses annexes, un catalogue illustré
Since the middle of the 19th century, the work of Jean-Baptiste Camille Corot (1796-1875) has provoked a plethora of analytical and scientific studies and books. Yet research on this famous artist can still prove fruitful. In this thesis, I have carried out a topographical study on a limited corpus of his art. Ville-d’Avray serves this purpose well, partly because the history of the area can be found in various archives and also because Corot attempted his first work alla prima there and returned each year in the family house to paint. Although this corpus is mainly made up of landscapes, it is also included portraits, decorative panels and religious subjects ; different graphic techniques, such as engraving, are also present. This unusual approach to studying a work allows us to confirm our present knowledge (date and history of the paintings, specific places which are represented). It also allows for a very precise interpretation of Corot’s method (which places he frequented, whether he worked outdoors or in the studio, the rhythm of his output, if he altered his earlier works), and in particular how his work developed over time (the visual aids he used – nature, drawings, engravings or painted studies – or mental aids – memory, imagination, souvenirs), thus helping us to deduce the realism of his landscapes. In addition, it also provides tangible clues to help authenticate the paintings which haunt the art market. This thesis is divided into two parts : an analytical summary with appendices and an illustrated catalogue

Abstract:

Giacomo Tazzini, architect of three courts. Life and work by a versatile architect-engineer in Milan, from Repubblica Cisalpina to Italian Unification.PhD thesis by Flavio Eusebio The name of Giacomo Tazzini often comes out in many documents of restoration of buildings in Milan, Monza and other Lombard sites. Nonetheless it hasn’t been never realized a specific research about his work. Tazzini doesn't represent only a stylistic and professional continuances with his master Luigi Canonica. In forty years he creates some extraordinary works, for the aesthetic and the technique, that have changed the face of Milan. The matrix of the aesthetic taste of the facades of his buildings is the Neoclassic one, but in the interiors it is possible to see a progressive evolution of the ornamental language. The works of Tazzini are very numerous if we consider not only court's assignments such as Royal Palace and the Scala Theatre, but even buildings and interiors for private commitment such as Spinola Palace. These assignments took place in Milan and in other Lombard cities. Sometime he used to design churches even if most of the time the architect that projected these sacred buildings was Tazzini's brother Giuseppe. The presence of Giuseppe has often determined confusion in attributions of altars or facades' projects.The quantity and quality of discovered drawings made by Tazzini show a very clever figure, great architect and engineer and interior designer, able to consider all the details from the door-handles to the chandeliers. Tazzini represents one of the final complete designer. He has not studied at the university but at Canonica's studio. Considering the hugeness of the documents discovered the research examines only the most important works in Milan, as defined in the subtitle.

Abstract:

La tesi intende offrire una riflessione in merito al potere degli organi giurisdizionali di disporre normativamente su determinati aspetti del processo che si svolge dinanzi ad essi, sostituendosi così al legislatore.Il piano di indagine della tesi si sviluppa prevalentemente nella descrizione della realtà europea davanti alle autorità giurisdizionali di Lussemburgo, attraverso continui riferimenti a pronunce giurisprudenziali.La candidata si sofferma, preliminarmente, definendo, in termini generali, l’origine e l’applicazione dei c.d. atti di soft law in ambito europeo e soffermandosi sul ruolo che ricopre la giurisprudenza nell’ordinamento europeo.Sempre nel capitolo di apertura, un accenno è dedicato al panorama italiano che, alla luce delle recenti e continue riforme processuali ed, in particolare, della lettura costituzionalmente orientata del processo civile in forza della sua ragionevole durata, sta conoscendo, sempre più largamente, il fenomeno dei c.d. protocolli.La tesi si sviluppa, poi, in altri tre capitoli, nei quali sono analizzati tre esempi di manifestazione del potere normativo degli organi giurisdizionali europei sul processo.La candidata passa, così, all’esame delle “Istruzioni pratiche alle parti”, sviscerando le disposizioni ivi contenute alla luce di casi giurisprudenziali, al fine di poter definire la reale efficacia di tali atti e la loro vincolatività nei confronti dei rappresentanti delle parti. A tale capitolo segue quello sull’applicazione del rinvio pregiudiziale tra soft law (c.d. Raccomandazioni) e giurisprudenza.Infine, la candidata svolge le ultime riflessioni sul potere “eccezionale” della Corte di giustizia di limitare nel tempo gli effetti delle proprie sentenze interpretative. Potere che, in questo caso, si manifesta non mediante l’emanazione di atti di soft law, ma attraverso le proprie pronunce giurisprudenziali.
The thesis aims to reflect on the power of the courts to provide normatively on some aspects of the proceedings that take place before them, thus replacing the legislator. The investigation plan of the thesis is developed considering the European situation before the courts of Luxembourg, through continuous references to cases law.The candidate focuses, firstly, defining, in general terms, origin and application of so-called soft law acts in Europe and focusing on the role of jurisprudence in the European system.In the first chapter, a hint is dedicated to the Italian overview, in the light of recent reforms of civil proceedings and with particular reference to the phenomenon of so-called “protocols”.The thesis is then developed in three other chapters, in which the candidate analyzes three examples of the manifestation of normative power of the European Courts on the proceedings.The candidate examines the "Practice Directions to parties": identifying the provisions contained in the light of cases law, in order to define the real effectiveness of these acts and their binding against parties’ representatives.The third chapter is about preliminary ruling procedure between soft law (so-called “Recommendation to national courts and tribunals in relation to the initiation of preliminary ruling proceedings) and jurisprudence.In the end, the candidate plays the latest reflections on "exceptional" power of the Court of Justice of the European Union to limit the temporal effects of its interpretative judgments. Power which, in this case, is manifested not through the enactment of soft law acts, but through its case law.

Abstract:

La presente tesi si concentra sull'effettività che la garanzia formale dei diritti, oggetto di proclamazioni al di fuori dei confini statali, riceve dalla tutela giurisdizionale della Corte europea dei diritti dell’uomo e della Corte di Giustizia dell’Unione europea. L'analisi si sofferma sull’impatto delle pronunce dei “giudici europei” nel sistema di protezione nazionale e sulle scelte del legislatore in materia di diritti. Gli ambiti presi in considerazione sono i seguenti: "nuovi diritti", materia penale, "violazioni strutturali".
The topic of the research is the "judicial dialogue" on human rights which involved the European Court of Human Rights, the European Court of Justice and the national courts and its impact on the national reforms. In the Italian system the "dialogue" between different jurisdiction created an effectiveness protection of human rights, for instance, on the prisoners rights.

Abstract:

Muovendo dai problemi rappresentati dall'incertezza del diritto legislativo e dall'ncertezza scientifica, l'elaborato intende indagare il rapporto tra scienza e diritto dal particolare punto di vista delle Alte Corti: Corte costituzionale, Corte di giustizia dell'Unione europea e Corte EDU. Per fare ciò il materiale giurisprudenziale sarà analizzato da due punti di vista distinti e complementari: il primo profilo mira a indagare attraverso quali strumenti la scienza entra nelle corti, specie in carenza di un effettivo utilizzo dei poteri istruttori. Il secondo profilo mira invece a vagliare l'utilizzo della scienza nell'iter decisionale, vedendo se e in che misura questa viene usata in maniera conclusiva.

Abstract:

La ricerca ha lo scopo di analizzare l’elusione tributaria da tre prospettive –sostanziale, sanzionatoria e processuale – prendendo spunto dal continuo dialogo tra i giudici nazionali e le corti europee sul tema.Nella prima parte della tesi, delineati in via di prima approssimazione i confini delle condotte elusive, lo studio è condotto attraverso l’analisi degli strumenti di contrasto di matrice normativa e giurisprudenziale: i secondi, in particolare, sono descritti seguendo l’evoluzione della giurisprudenza della Corte di Cassazione, la quale, dopo l’iniziale ricorso allo strumento civilistico della nullità del contratto, è giunta alla creazione di un principio generale antielusivo, mutuandolo – impropriamente – dal divieto di abuso del diritto europeo.Nella seconda parte, l’indagine è focalizzata sulla rilevanza dell’elusione tributaria ai fini dell’applicabilità delle sanzioni amministrative e penali. Dopo una breve ricognizione normativa, sono ricostruite le soluzioni individuate dalla dottrina e dalla giurisprudenza. In conclusione, si tenta di risolvere la questione attraverso il suo inquadramento nell’ambito del diritto punitivo.L’obiettivo che si persegue nella terza parte della tesi è quello di verificare se sia configurabile, in capo al giudice tributario, il potere di rilevare ex officio la violazione del principio generale antielusivo di matrice pretoria, nonché, nel caso di stimata rilevabilità ex officio, quali siano le forme di esercizio di tale potere officioso, vale a dire se il giudice tributario debba previamente sottoporre la questione alle parti ovvero se possa definirla senza attivare un contraddittorio specifico.

Abstract:

The main objective of this thesis is to meet Governance as a new approach in company organization, especially in IT sector. The idea is about harmonization of IT and business strategy, that should ensure achieving company goals and missions, and lead company in the right direction of advancement, what is directly connected with implementation of relevant measures of IT processes. As chapter "Governance", is describing how this approach should by ensure in whole organization on a different levels. We can translate Governance as implementation of certain best practices and procedures that lead company to process standardization and formalization. The most exercising methodologies and guidelines in IT sphere as ITIL, Val IT, CobiT, ISO 27000 are reviewed in thesis. By these methodologies organizations should be able to better optimize processes and accomplish regulation frame in particular industry. Another very important contribution of process standardization is by providing better possibilities for measurement and assessment, that is reviewed in chapter "Evaluation of IT processes performance". There is also transparent guideline which provides a simple steps procedure how to implement IT Governance in organization using CobiT and Vat IT. As this branch is relatively "young", especially in Czech Republic, management is still familiarizing with it. Last chapter is dedicated to analyze approach to ITG in Czech Republic banking sector.

Abstract:

Thesis (S.B.)--Massachusetts Institute of Technology, Dept. of Physics, 2010.
Cataloged from PDF version of thesis.
Includes bibliographical references (p. 57).
In this thesis, publically available data from the French/ESA satellite mission CoRoT, designed to seek out extrasolar planets, was analyzed using MATLAB. CoRoT attempts to observe the transits of these planets across their parent stars. CoRoT occupies an orbit which periodically carries it through the Van Allen Belts, resulting in a very high level of high outliers in the flux data. Known systematics and outliers were removed from the data and the remaining scatter was evaluated using the median of absolute deviations from the median (MAD), a measure of scatter which is robust to outliers. The level of scatter (evaluated with MAD) present in this data is indicative of the lower limits on the size of planets detectable by CoRoT or a similar satellite. The MAD for CoRoT stars is correlated with the magnitude. The brightest stars observed by CoRoT display scatter of approximately 0.02 percent, while the median value for all stars is 0.16 percent.

Abstract:

Les étoiles Be représentent environ 20% des étoiles B de la Galaxie. Elles possèdent une enveloppe circ*mstellaire formée par des éjections discrètes et récurrentes de matière provenant de l'étoile. Ce sont aussi des étoiles pulsantes et en rotation rapide. De ce fait les étoiles Be ont des caractéristiques pulsationnelles spécifiques, pouvant être étudiées grâce à CoRot, lancé avec succès le 27 décembre 2006. CoRot permet pour la première fois d'étudier systématiquement le lien entre les pulsations des étoiles Be et les flots de matière alimentant le disque circ*mstellaire. Ma thèse a pour objectif de traiter les données CoRot d'étoiles Be observées dans les tout premiers runs. Le traitement des données a nécessité au préalable l'amélioration des méthodes de recherche de fréquences afin de traiter un grand volume de données de haute précision. J'ai donc développé un outil de traitement de données TISAFT (Time Series analysis with Fisher's Test), qui extrait les fréquences des données photométriques de CoRot et qui utilise un critère statistique pour déterminer la significativité des résultats. J'ai ensuite étudié les données photométriques de l'étoile Be HD49330 observée avec Corot pendant 137 jours ainsi qu'en spectroscopie au sol pendant 20 nuits cumulées. HD49330 a présenté durant les observations un sursaut de lumière qu'on a associé à une éjection de matière. Les amplitudes du signal associées aux principales fréquences de HD49330 varient tout au long du sursaut de lumière de manière clairement corrélée avec ce dernier. HD49330 est aussi une étoile hybride du point de vue des pulsations : elle possède des modes p typiques des β Cephei et des modes g typiques des SPB
Be stars represent about 20 % of the B-type stars in our Galaxy. These stars are surrounded by a circ*mstellar envelope fed by discrete and recurrent material ejections that come from the star. These stars are also pulsating and rapidly rotating stars. That is why Be stars have specifics pulsational features, that can be studied by the CoRoT satellite, successfully launched on the 27th December 2006. For the first time, CoRoT allows us to systematically study the link between pulsations of Be stars and material outflows that give rise to the circ*mstellar disk. The purpose of my PhD thesis work is to analyse the CoRoT data of Be stars observed in the first observations runs. Firstly, the data processing required improvements of the frequency searching methods in order to analyse a huge volume of data with high accuracy. Therefore, I developed a data processing tool, called TiSAFT (Time Series Analysis with Fisher's Test of significance), that extracts the frequencies embedded in the CoRoT photometric data. TiSAFT uses a statistical criterium to determine the significance of the results. Secondly, I analysed the photometric data of the Be star HD49330 observed with the CoRoT during 137 days and with ground-based spectroscopy during a total period of 20 nights. HD49330 showed a luminosity burst during the observations that we associated to a material ejection. The amplitudes of the signal associated with the main frequencies HD49330 change all along the light burst and are clearly correlated with the burst. Moreover, concerning the caracteristics of the pulsation modes. HD49330 is an "hybrid" star : we found p modes typical of β Cephei stars and g modes typical stars

Abstract:

Dans le cadre de ma thèse, j'ai effectué l'analyse spectrale d'un échantillon massif de spectres stellaires dans le contexte du programme exoplanète de la mission CoRoT. J'ai tiré avantage des instruments Flames/GIRAFFE pour observer près de 2000 étoiles dans le but de comprendre les populations stellaires dans les champs CoRoT. Dans ce but, j'ai implémenté, calibré, testé, et appliqué une chaîne de traitement et de réduction fiable et efficace afin de réduire et d'analyser automatiquement (en utilisant l'algorithme de paramétrisation MATISSE, Gazzano et al. 2010) un large échantillon de spectres stellaires. J'ai déterminé la vitesse barycentrique radiale, une estimation de la vitesse de rotation projetée sur la ligne de visée, la température effective, la gravité de surface, de la métallicité global et l'enrichissem*nt des éléments par rapport au fer pour 1 227 étoiles dans trois des champs CoRoT. Ainsi, j'ai construit un des premiers échantillons affranchis de biais de sélection pour toute étude concernant la relation planète métallicité dans les champs CoRoT et démontré que le nombre des étoiles naines a été généralement sous-estimé par la classification photométrique (Exo-Dat, Deleuil et al. 2009). J'ai appliqué la relation reliant le nombre de planètes détectées à la métallicité de l'étoile hôte (Udry & Santos 2007), parfaitement en accord avec le nombre actuel de détection planétaire dans les champs CoRoT correspondant (Gazzano et al. 2010). En utilisant les paramètres atmosphériques MATISSE, nous avons déterminé les distances et nous les avons combinées avec des informations cinématiques (les mouvements propres du catalogue PPMXL - Roeser et al. (2010), et l'astrométrie). Nous avons dérivé les composantes de cinématique Galactique : position et vitesse. Cela m'a permis d'étudier les populations stellaires dans les champs CoRoT /exoplanète et de quantifier le gradient de métallicité dans la Galaxie (Gazzano et al. En préparation). J'ai par ailleurs montré que les étoiles à planètes détectées dans les champs considérés pour ma thèse sont exclusivement des étoiles de disque mince. J'ai également participé au suivi des candidats planète CoRoT à l'aide de spectroscopie à haute résolution. J'ai effectué l'analyse spectrale, avec le logiciel VWA (Bruntt et al. 2010b,a), des étoiles hôtes pour la mission spatiale CoRoT. Ces études ont conduit à la détermination des paramètres fondamentaux de l'étoile, qui est une étape indispensable pour la caractérisation complète de la planète
During my Ph.D., I performed the spectral analysis of a massive sample of stellar spectra in the context of the CoRoT /Exoplanet mission. We took advantage of the Flames/GIRAFFE multi-fibre instrument to observe almost 2 000 stars with the aim of understanding the stellar populations in the CoRoT fields. To these purposes, I implemented, calibrated, tested and applied an automatic pipeline to reduce and analyse automatically (using the parameterization algorithm MATISSE, Gazzano et al. 2010) a large sample of stellar spectra. I derived the barycentric radial velocity, an estimate of the rotational velocity projected on the line of sight, the effective temperature, the surface gravity, the overall metallicity and the -enhancement for 1227 stars in three of the CoRoT fields. Hence, I built one of the first unbiased samples for any study regarding planet metallicity relationship in the CoRoT fields and demonstrated that the amount of dwarf stars was generally underestimated by the photometric classification (in Exo-Dat, Deleuil et al. 2009). I applied the relationship linking the number of planets as a function of the metallicity of the host star (Udry & Santos 2007), totally in agreement with the current number of planetary detection in the corresponding CoRoT fields (Gazzano et al. 2010). Using MATISSE atmospheric parameters, we determined distances and combining them with kinematics information (proper motions from PPMXL catalogue - Roeser et al. (2010) and astrometry), we derived Galactic kinematics components : position, velocities and orbits. This allowed me to study the stellar populations in the CoRoT /Exoplanet fields and quantify the metallicity gradient in the Galaxy (Gazzano et al. in preparation). I also participated to the spectroscopic follow-up observations of CoRoT planetary candidates with high resolution spectroscopy, to the spectroscopic analysis, with the VWA software (Bruntt et al. 2010b,a), of planet hosting stars for the CoRoT space mission and to their characterisation and publication. Indeed, the determination of the fundamental parameters of the star is a mandatory step for the complete characterisation of the planet

The transit photometry makes it possible to detect exoplanets by measuring their radii. Pursuing this goal, the space telescope CoRoT (Convection, Rotation and planetary Transits), launched in December 2006, is equiped with a high-precision photometer allowing both planet detection by transit photometry, and stellar physics studies (asteroseismology).For this PhD thesis, I have developed various computing tools for the detection and detailed analysis of the transits in CoRoT light curves. I have applied these tools to almost 12 000 stars observed during each of the first ten campaigns of observation. The collaboration between the detection and ground based follow-up teams led to the discovery, up to now, of fifteen planets and two brown dwarfs.It is possible to constrain the physical natures of these exoplanets thanks to the knowledge of the masses and radii: they can be gazeous, icy, rocky or with an mixed nature.The search for rocky planets in particular, is a goal motivated by their singular nature, and both by the paucity of detections of these objects (due to their low masses and radii), Thus, the discovery of CoRoT-7b -- the first exoplanet compatible with a rocky model and whith measured radius (1.6 Earth radius) and mass (around 7 Earth masses) -- allowed us to develope a physical model to which I contributed :I studied the possibility of observing this very hot planet in the near infrared range with JWST, during its orbit, to estimate the temperature contrast between the day and the night faces. This should allow to confirm / invalidate our model with atmosphere dense enough to redistribute heat at the surface of CoRoT-7b

Abstract:

Thesis (MAcc (Accountancy))--University of Stellenbosch, 2007.
The purpose of this assignment is to ascertain whether the COBIT framework is an adequate framework to assist in the governance of virtual private networks. The assignment focuses on whether the framework can ensure the identification of virtual private network-related risks and address IT compliance with policies and statutory regulations.A brief summary of the risks and issues pertaining to the pre-implementation, implementation and post-implementation phases of virtual private networks is included in the assignment. These risks and issues are then individually mapped onto a relevant COBIT control objective. The scope of the assignment does not include the intricacies of how these networks operate, the different types of network topologies or the different technologies used in virtual private networks.It was found that the COBIT framework can be implemented to manage and/or mitigate virtual private network risks.

Abstract:

Em Cestódeos, o processo de estrobilização é aquele que leva ao desenvolvimento da fase adulta a partir da larva, conferindo uma grande vantagem adaptativa a esses organismos através do aumento da fecundidade e dispersão. Mesocestoides corti vem sendo utilizado como modelo de estudos de diversos aspectos envolvidos na estrobilização. Neste trabalho, empregaram-se abordagens proteômicas no estudo de tetratirídeos que foram expostos ou não a tratamento de indução de segmentação (IN e TT, respectivamente): eletroforese bidimensional (2DE) seguida de MALDI-TOF MS ou MS/MS e a análise de extratos por LC- ESI-Q-TOF MS/MS. Através da 2DE-MALDITOF MS ou MS/MS, foram definidos os padrões 2DE de TT e IN nas faixas de pH 3-10 e 4-7. Foi possível identificar sete proteínas e obter dados de massa para mais 106 spots em tetratirídeos, e uma proteína e 66 spots em tetratirídeos após indução de estrobilização. Quando o perfil eletroforético das amostras foi analisado, foram evidenciados 102 spots diferencialmente expressos. Através de LC-ESI-Q-TOF MS/MS, foram identificadas 80 proteínas entre as duas fases, sendo 17 exclusivas de TT, 21 exclusivas de IN e 42 comuns a ambas. Essas proteínas foram caracterizadas funcionalmente em 18 grupos de acordo com o Dentre as proteínas identificadas, foram verificadas algumas com funções secundárias relacionadas ao controle de expressão gênica e algumas com papel relacionado à imunogenicidade do hospedeiro. Através da análise do emPAI das proteínas nos dois extratos, foram verificadas 12 proteínas com alterações quantitativas na expressão. Dessa forma, através desse trabalho, foi possível a caracterização preliminar dos perfis protéicos de tetratirídeos e induzidos, obtendo-se alguns indícios dos mecanismos envolvidos na diferenciação de M. corti em nível proteômico.
In Cestodes, the strobilation process leads to the development of the adult form from the larvae, giving a great adaptative advantage to these organisms by increasing the fecundity and spread. Mesocestoides corti has been used as a model for the study of varius aspects involved in strobilation. In this study we employed proteomic approaches in the study of tetrathyridia that had been exposed or not to segmentation induction treatment (IN and TT, respectively): two0dimensional gel electrophoresis (2DE) followed by MALDITOF MS or MS/MS and analysis of extracts by LC-ESI-Q-TOF MS/MS were performed. By 2DE-MALDI-TOF MS or MS/MS the proteomic profile of TT and IN on the pH range of 4-7 and 3-10 were defined. Seven proteins could be identified and mass data for further 106 spots were obtained for TT samples, and, from IN samples, one protein was identified and mass data was obtained for 66 spots. When 2DE profiles of TT and IN were compared, 102 spots were differentially expressed. Through LC-ESI-Q-TOF MS/MS, 80 proteins were identified within two samples, 17 exclusive from TT, 21 from IN and 42 common to both. These proteins were function characterized in 18 groups according to KOG. Among the proteins identified, we observed some with secondary roles related to gene expression control and some related to host immunogenicity. Through emPAI analysis, 12 showed quantitative differences in expression. Through this work, it was possible to preliminarily characterize the protein profiles of TT and IN and, thus, obtain some evidence of the mechanisms involved in the differentiation of M. corti in the proteomic level.

Abstract:

The interiors of the stars are among the most difficult parts of the Universe toobserve. Essentially, asteroseismology tries to make use of the oscillations toprove the stellar interiors, which are not directly observable. The basicprinciples of asteroseismology are, to a certain extent, similar to thosedeveloped and employed by Earth seismologists. Asteroseismology relies onadvanced mathematical descriptions of oscillations in a three-dimensional bodyand numerical modeling. It is therefore a prominent example of interdisciplinaryscience.The general aim of this work is the study of Be stars with the CoRoT spacemission. Classical Be stars are B-type stars that exhibit line emission over thepho- tospheric spectrum. The excess is attributed to a circ*mstellar gaseouscomponent that is commonly accepted to be in the form of an equatorial disk.The mechanisms responsible for the production and dynamics of thecirc*mstellar gas are still not constrained. Observations of non-radial pulsationbeating phenomena connected to outbursts point toward a relevance ofpulsation, but this mechanism cannot be gene- ralized. In this regard, theobservation of classical Be stars with the high-precision CoRoT satellite isproviding important keys to understand the physics of these objects and thenature of the Be phenomenon.In order to study the light variations of the selected stars we use photometricand spectroscopic observations. These observations allow us to extractfrequencies, amplitudes and phases of these variations. As we will show, theselight variations can be connected with pulsations on the stellar surface. Forcarrying out the frequency analysis we have developed a new code based onstandard Fourier analysis. The point is that this code, called pasper, allows thefrequency analysis of large sets of light curves in an automatic mode.This Ph.D. thesis is arranged as follows: In the first three Chapters we describethe scientific framework of this project, giving a brief description on Asteroseismology,presenting the current status of Be stars, and describing the basics ofthe Fourier analysis and the rudiments of the time series analysis.At the early begin of this Ph.D. thesis, the CoRoT satellite was still on groundgetting ready for the launch. In this context, we perform a search for shortperiodB and Be star variables in the low metallicity environment of theMagellanic Clouds. This study constitutes the Part I of this Ph.D. thesis. ThisPart has a double goal: i) to test the frequency analysis codes; and ii) to detectobservationally β Cephei and SPB-like B-type pulsators in low metallicityenvironments, actually not predicted by the pulsational theory and models. Thisconstitutes the Part I.Part II is devoted to the study of Be stars with the CoRoT space mission. Herewe depict a complete review on the CoRoT mission. We also describe theresults on the analysis of three Be stars from the CoRoT exoplanet field. Finally,we present the results on the frequency analysis of the late Be star HD 50 209,observed in the seismology field of the CoRoT satellite. The analysis of this Bestar has revealed up to sixty frequencies, grouped in six different and separatedsets, attributed to g-mode pulsations.Finally, we resume the main conclusions of the whole project, including prospectsand future work to be done. An addendum with all the published resultsderived from this project has been added at the end of this Part II. Part III enclosesthe Appendixes, providing a brief summary of this work in Spanish, acomplete description on basic equations of non-radial oscillation, the user guideof the PASPER code and the user guide of the KURTZ_BOS code.
El objetivo de la asterosismología es describir el interior de las estrellas a partirde las oscilaciones. El interior de las estrellas es, posiblemente, el lugar másdifícil de estudiar de todo el Universo, ya que las condiciones especiales queallí se dan no pueden reproducirse en ningún laboratorio terrestre. Así, laimportancia de esta ciencia en el estudio global de la física estelar es crucial.Los principios básicos de la asterosismología son, en esencia, similares a losque los geólogos usan en el estudio de terremotos terrestres. Laasterosismología hace uso de descripciones matemáticas de las oscilacionesen cuerpos tridimensionales, creando para ello sofisticadas simulacionesnuméricas. Es, por tanto, un claro ejemplo de ciencia multidisciplinar.El objetivo general de esta Tesis Doctoral es el estudio de las estrellas Be conlas misión espacial CoRoT. Las estrellas Be son objetos de secuencia principal,con alta velocidad de rotación, que presentan un exceso infrarrojo y emisión enlas líneas de Balmer, debido a la presencia de una envoltura circumestelarconcentrada en el ecuador y generada por eyecciones discretas de materiaoriginado por mecanismos que todavía no son bien conocidos. Losmecanismos propuestos para explicar la eyección de materia son hasta ahora,las pulsaciones no radiales combinadas con la alta velocidad de rotacióncaracterística de este tipo de estrellas. La observación de estrellas Be con elsatélite de alta precisión CoRoT está aportando claves importantísimas paracomprender la física de estos objetos y la naturaleza del fenómeno Be.Para la detección de señales periódicas en las estrellas seleccionadasutilizamos tanto observaciones fotométricas como espectroscópicas. A partir delas observaciones obtenemos las frecuencias, amplitudes y fases de lasvariaciones. Como se muestra en la tesis, las variaciones en las curvas de luzestudiadas podrían estar estrechamente relacionadas con los mecanismos depulsación estelar. Para realizar el análisis de frecuencias hemos desarrolladoun código basado en técnicas estándar de análisis de Fourier. Este código,llamado Pasper, nos permite analizar grandes conjuntos de datos de forma casiautomática.

Abstract:

On a tout lieu de croire que les oscillations acoustiques du Soleil, qui sont sujettes à différents mécanismes complexes d'amortissem*nt, sont excitées stochastiquement par les mouvements incohérents de matière dans la zone convective.
Ces mouvements turbulents sont à l'origine d'une puissance acoustique injectée dans les oscillations et en assurent la survie. On désigne alors par oscillations de type solaire des oscillations acoustiques excitées par ce mécanisme, elles concernent les étoiles de masse intermédiaire dotées d'une zone convective supérieure.
Pour peu que des mesures précises d'amplitude et d'amortissem*nt soient disponibles il est possible d'évaluer cette puissance acoustique et de contraindre la physique du phénomène.
Dans ce travail les bases de cette théorie ont été reconsidérées : les inconsistances ont été identifiée et supprimées et les controverses entre les auteurs précédents résolues. Il en résulte une nouvelle formulation qui généralise le traitement de la turbulence.
Le terme d'advection des fluctuations turbulentes de l'entropie par le champ de vitesse est identifiée comme la source d'excitation dominant largement la source liée au stress de Reynolds.
Les études quantitatives effectuées pour un modèle du Soleil et de Procyon ont révélé la grande sensibilité aux paramètres libres, introduits dans la théorie, ainsi qu'à la modélisation de la turbulence. L'application de cette formulation à des étoiles de masse intermédiaire ( 1 M o< M < 2 Mo) de la séquence principale a mis en évidence des effets systématiques relatifs aux paramètres stellaires : plus l'étoile est chaude plus la sensibilité au spectre de turbulence est exacerbée et plus elles sont porteuses d'information.
La future mission spatiale COROT devrait collecter des données de haute qualité sur ce type d'étoile. Dans cette perspective et pour optimiser le retour scientifique nous avons développé un modèle numérique de la chaîne photométrique de l'instrument. Ce modèle nous a permis d'apprécier la réponse de l'instrument que nous avons alors convolué avec nos estimations des puissances.
On établit que les hautes performances de COROT devraient être capables de nous fournir les contraintes observationnelles sur la théorie développée dans le présent travail.

Abstract:

Type II transmembrane serine proteases (TTSPs), including hepsin and corin, are a new class of cell surface catalytic enzymes. In the present study, a non-transmembrane isoform of hepsin, named hepsin/-TM that originates from alternative splicing, was identified. Unlike the transmembrane hepsin isoform, this non-transmembrane isoform was distributed within the cytoplasm and likely to be modified after translation. Real-time PCR experiments revealed that hepsin was expressed in all tested human tissues, but hepsin/-TM only in kidney, brain and lung tissues. Significantly, hepsin/-TM was not expressed in liver where hepsin was originally identified. However, hepsin/-TM was highly expressed in brain where hepsin was expressed at a significantly lower level. Moreover, these two isoforms showed different expression patterns in several colon cancer cell lines. Furthermore, ten corin-interacting proteins were identified and a variety of corin mutants were generated for the studies of the relationship of corin structure and function.

ENGLISH ABSTRACT: Cloud computing has emerged as one of the most hyped information technology topics of the decade. Accordingly, many information technology service offerings are now termed as cloud offerings. Cloud computing has attracted, and continues to attract, extensive technical research attention. However, little guidance is given to prospective consumers of the cloud computing services who may not possess technical knowledge, or be interested in the in-depth technical aspects aimed at information technology specialists. Yet these consumers need to make sense of the possible advantages that may be gained from utilising cloud services, as well as the possible incremental risks it may expose an enterprise to.The aim of this study is to inform enterprise managers, who possess business knowledge and may also be knowledgeable on the main aspects of COBIT, on the topic of cloud computing. The study focuses on the significant benefits which the utilisation of cloud computing services may bring to a prospective consumer enterprise, as well as the significant incremental risks this new technological advancement may expose the enterprise to. Proposals of possible controls that the prospective consumer enterprise can implement to mitigate the incremental risks of cloud computing are also presented.
AFRIKAANSE OPSOMMING: “Cloud computing” (wolkbewerking) het na vore getree as een van die mees opspraakwekkende inligtingstegnologieverwante onderwerpe van die dekade. Gevolglik word talle inligtingstegnologie-dienste nou as “cloud”-dienste aangebied. Uitgebreide aandag in terme van tegnologiese navorsing is en word steeds deur “cloud computing” ontlok. Weinig aandag word egter geskenk aan leiding vir voornemende verbruikers van “cloud”-dienste, wie moontlik nie tegniese kennis besit nie, of nie belangstel in die diepgrondige tegniese aspekte wat op inligtingstegnologie-spesialiste gemik is nie. Tog moet hierdie verbruikers sin maak van die moontlike voordele wat die gebruik van “cloud”-dienste mag bied, asook die moontlike inkrementele risiko’s waaraan die onderneming blootgestel mag word.Die doel van hierdie studie is om die bestuurders van ondernemings, wie besigheidskennis besit en moontlik ook kundig is oor die hoof aspekte van COBIT, in te lig oor wat “cloud computing” is. Die studie fokus op die beduidende voordele wat die benutting van “cloud computing”-dienste aan die voornemende verbruikersonderneming mag bied, asook die beduidende inkrementele risiko’s waaraan die onderneming blootgestel mag word as gevolg van hierdie tegnologiese vooruitgang. Voorstelle van moontlike beheermaatreëls wat die voornemende verbruikersonderneming kan implementeer ten einde die inkrementele risiko’s van “cloud computing” teë te werk word ook aangebied.

ERP applications have evolved into enterprise-wide applications, which are generallyacknowledged today as a critical component in an organisation’s information strategy.When implementing an ERP application, the control and governance of all IT processesare critical to ensure that value is delivered, risks are managed and that the investmentin IT (ERP) delivers a reasonable return.It should, therefore, be important to focus on mitigating IT process risks that have animpact on the ERP environment, so that the level of residual risk is acceptable andaligned with the business objectives.This assignment focuses on using the generally accepted IT framework, COBIT (ControlObjectives for Information and related Technology), as governance and control model.The criticality of each COBIT control objective (IT process) is evaluated by applying theCOBIT control objectives in an ERP environment. Specific reference is also made toQmuzik as an ERP application.By applying COBIT in an ERP environment, the most critical IT processes applicable toERP are identified, in order to ensure that the minimum process controls for these ITprocesses are designed and implemented.
