Full textAbstract:
Purpose: The aim of this bachelor thesis is to investigate the relationship of online subcultures, electronic trust, electronic word-of-mouth, and purchase intention towards a special event within selected Facebook Pages. Background: Given the increasing impact of social media platforms in communications not only between consumers, but also consumers and companies, this study takes a deeper look at the influence that companies can exercise on consumer’s purchase intention for a special event through these platforms. The background is based on previous researches and existent theories related to products, which are tested for a special event. Method: In order to fulfill the purpose of this study a cross-sectional design is applied. A deductive approach is followed, and a quantitative method is used through the application of questionnaires in order to collect the empirical data necessary to answer the given research questions. The questionnaires were distributed to the selected sample, which is anyone who “likes” the following Facebook Pages: Sweden Rock Festival, Göteborg Horse Show, Hultsfred, and Swedish Speedway Grand Prix. Conclusion: Based on the background a modest to strong relationship was expected between the measured variables. This however has been disconfirmed by the results, thus showing a weaker relationship than has been previously tested with regards to a product. The main finding is that when it comes to special events, the organizer is seen as a more reliable source, thus it is more influential than fellow members of the Facebook Page.

Full textAbstract:
This thesis investigated trust over the Internet to seek a better understanding of trust and ways to increase trust in online transactions. The focus of this investigation was consumer-to-consumer transactions at online auctions where key actors were virtually anonymous to each other. The perceptions of a broad range of online auction community members support this thesis. Normative and grounded theoretical perspectives of trust and factors that affected trust were considered, compared and contrasted as part of this research. Concept mapping and the Theory of Planned Behaviour (TPB) were used to underpin the grounded theoretical perspective of trust developed as part of this thesis. Online auction cases were selected and analysed to check the grounded theoretical perspective of trust developed. This thesis provided a better understanding of trust, provided new insights into trust and distrust, added to the body of theory for trust and identified ways to increase trust in online transactions. This thesis provided better understandings of: trust; moral obligations; network decision structures; power; fairness; and perceived behavioural controls at online auctions. A grounded theoretical model of trust based in TPB was developed that was specific to online auctions. This model of trust developed appeared to provide clearer and richer insights into online auction trust. The model of trust developed identified factors and constructs that affected trust rather than the magnitude of any affects. The model developed and findings of this thesis can be applied to new or specific online auction sites to help practitioners build better online environments to encourage more people to transact rather than just browse online. The grounded theoretical perspective of trust and findings of this thesis may be relevant to other online consumer-to-consumer transactional environments.

Full textAbstract:
The following work is the result of three years of research for my Ph.D. at the University of Trento, Faculty of Law. The aim of my research is to give an account of the Etruscan legal system by analysing both direct and indirect sources. For this, I have attempted to use historical, linguistic, and epigraphical methods and instruments, combining them to offer the most complete view of one of the most influential cultures in the Italian peninsula before the rise of Rome.
The first chapter is an account of the historical evolution of the Etruscan ethnos from the Bronze age to the end of the I century b.C., focusing mainly on the socioeconomic drives that informed public affairs and the complex exchequer of international events. This part is based on indirect sources, such as literary ones.
The second chapter is an attempt to offer a short linguistic vademecum, focused mainly on Etruscan alphabet and morphology, with some remarks regarding the origins of Etruscan language and alphabet.
The third chapter is the analysis of the direct sources, mostly epigraphic ones. I have chosen the most relevant legal epigraphs that have yet been discovered and have proceeded to study them, attempting (where possible) some parallels with roman law.
After the general conclusions, I deemed it appropriate to add two appendixes concerning Etruscan amgistratures and a short legal lexicon.
The work is closed by some hand-drawn maps and the most important epigraphs.

In the gneissic rocks of the Rio Urubu Metamorphic Suite that emerge in Serra Repartimento, with a metamorphic Sn foliation, and locally with meso to ultramilonitic textures, and milonitic Sn+1 foliation, would have been generated under conditions of amphibolite-granulite facies, at a metamorphic peak temperature of ~ 773 °C and pressure of ~ 6,5 Kbar. Syn-kinematics plutons of gabbros settled during a tectonometamorphic event in the Orosiriano during the activation of shear zones, with crystallization conditions close to 1219 °C and metamorphism in amphibolite facies with temperature of ~ 784 °C and pressure of ~ 6,0 Kbar. The Mesozoic gneiss rocks were affected by tafrogenic processes, intruded by alkaline magmatism associated with the opening of the Tacutu graben, and hydrothermal alteration derived from the fluxo of hydrothermal fluids. These hydrothermal post-magmatic fluids related to alkaline plutonism, rich in Na, Ca, K, incompatible elements and light rare earth elements (LREE), migrated and percolated the metamorphic rocks, generating enrichment in Ti and Nb. Rutile in veins, accompanied with fluorapatitas and zircon, are minerals that enclose anomalous contents of these latter elements formed by processes of hydrothermal alteration. The chemical and physical characteristics of the fluids showed the existence of the interaction of at least two different compositional systems, an aqueous one characterized by the H2O-NaCl system and an aquocarbonic characterized by the H2O-CO2-NaCl system. This hydrothermal fluid presents salinity up to 22% by weight of NaCl, with a higher concentration in the range of 15-20%, with minimum entrapment conditions at 457 °C and 3.3Kbars. The information obtained allows us to infer that the formation of the ore in the Serra Repartimento area is a result of a magmatic-hydrothermal system, with an alkaline magmatic source, with the transport of complex bonds of F-, Cl-, HCO3-, CO32-, HS- e S2– and metals (Ti, Nb and REE's), probably associated with the Apiaú Alkaline Complex, and mobilized in fracture zones associated with reactivations of the NE-SW and E-W shear zones during Tacutú graben formation.
Nas rochas gnáissicas da Suíte Metamórfica Rio Urubu que afloram na Serra Repartimento, com foliação metamórfica Sn, e localmente com texturas meso a ultramilonítica, com foliação milonítica Sn+1, teriam sido geradas em condições de fácies anfibolito-granulito, em temperatura de pico metamórfico de ~773°C e pressão de ~6,5 Kbares. Plútons de gabro sin-cinemáticos se acomodaram durante um evento tectonometamórfico no Orosiriano durante a ativação de zonas de cisalhamento, sendo que as condições de cristalização estiveram próximas de 1219 °C e as do metamorfismo em fácies anfibolito com temperatura de ~784°C e pressão de ~6,0 Kbares. As rochas gnáissicas no Mesozoico foram afetadas por processos tafrogênicos, intrudidas por magmatismo alcalino associado à abertura do graben de Tacutu, e alteração hidrotermal derivadas da passagem de fluidos hidrotermais. Tais fluidos hidrotermais tardi-magmáticos relacionados ao plutonismo alcalino, ricos em Na, Ca, K, elementos incompatíveis e elementos em terras raras leves (ETRL), migraram e percolaram as rochas metamórficas, gerando enriquecimento em Ti a partir do metassomatismo alcalino nos gnáisses, e Nb e ETR’s associados a fluidos alcálinos. Rutilo em veios, além de fluorapatitas e zircão, são minerais que contem teores anômalos de desses elementos formados pelos processos de alteração hidrotermal. As características físico-químicas dos fluidos mostraram a existência da interação de pelo menos dois sistemas composicionais diferentes, um aquoso caracterizado pelo sistema H2O-NaCl e um aquocarbônico caracterizado pelo sistema H2O-CO2-NaCl. Esse fluido hidrotermal apresenta salinidade de até 22% em peso de NaCl, com maior concentração na faixa de 15 – 20%, com condições minimas de atrapamento a 457°C e 3,3 Kbares. As informações obtidas permitem inferir que a formação do minério na área da Serra Repartimento é resultado de um sistema magmatico-hidrotermal, sendo a fonte magmática de caracter alcalino com transporte de complexos ligantes de F-, Cl-, HCO3-, CO32-, HS- e S2– e metais (Ti, Nb e ETR’s), provavelmente associado ao Complexo Alcalino Apiaú, e mobilizado em zonas de fratura associados a reativaçoes das zonas de cisalhamento NE-SW e E-W durante a formação do graben de Tacutu.

Full textAbstract:
Dans la chaine dinaro-albano-hellenique, les ophiolites des albanides (zone de mirdita) representent les temoins d'un bassin oceanique etroit forme a l'ouest de la zone du korab (=pelagonienne). Disposees geographiquement en deux ceintures, une orientale de type harzburgites (hot) et l'autre occidentale de type lherzolites (lot), elles constituent la nappe de mirdita reposant sur un soubassement sedimentaire, forme de trois ensembles principaux: le substratum carbonate triasico-jurassique, la serie volcano-sedimentaire du jurassique superieur et les roches metamorphiques de la semelle ophiolitique. L'histoire tectonique de la zone de mirdita comprend trois grandes periodes: la periode d'extension continentale, la periode oceanique et la periode de compression. La tectonique en extension des le trias moyen aboutit a une paleogeographie contrastee a domaines de sedimentation neritique et pelagique. L'achevement de l'extension au jurassique correspond a l'elargissement des marges continentales du futur bassin oceanique. Le rifting s'acheve par la formation de la serie volcano-sedimentaire et par l'injection de serpentinites le long de grandes fractures de la croute continentale. La periode oceanique est marquee par l'evolution d'une dorsale lente a une dorsale rapide interrompue par une subduction intra-oceanique responsable d'un volcanisme d'arc insulaire. L'hypothese d'une obduction a double vergence des ophiolites est demontree par l'analyse microstructurale effectuee dans la semelle metamorphique sous-jacente et par la mise en evidence d'un double systeme d'ecailles frontales, situe de part et d'autre des ophiolites. La tectonique des marges correspond a une inversion tectonique. Le charriage proprement dit des ophiolites (ou obduction) et la deformation des marges continentales de la zone de mirdita, se sont produits au jurassique terminal (ante-tithonique) et sont tres peu modifies lors de la tectonique tertiaire

Full textAbstract:
Ce que cette these se propose d'etudier, ce sont les idees et les images qui existaient a propos du diable au xiie siecle. Le terme "representation(s)" doit etre compris dans un sens tres large : il fait reference autant aux idees sur le diable existant dans la mentalite des hommes de cette periode et qui se refletent surtout dans certains traites theologiques qu'aux descriptions concretes du diable et des etres diaboliques qui apparaissent dans les oeuvres litteraires et dans l'iconographie de cette periode. Dans notre titre, a cote du diable apparaissent mentionnes les "etres diaboliques". Cette expression nous l'utilisons in senso lato. Pour nous les "etres diaboliques" sont des personnages aussi varies que les paiens, les juifs, les traitres, les geants ou certains animaux en rapport avec le monde diabolique comme les serpents et meme des monstres. Les representations du diable et des etres diaboliques sont etudiees par "genres" c'est-a-dire, dans les differentes formes d'ecriture car chacune de ces formes d'ecriture a des particularites, des caracteristiques, des publics qui lui sont propres et, il est evident que, elles vont revetir des formes differentes selon les "genres" et les publicsThis thesis in intended to study ideas and images related to the devil which existed in the 12th century. The term "representation(s)" has to be understood in a broad sense : this term refers not only to ideas about devil existing in the mentality of men that time, ideas which are reflected especially in some treatises on theology, but to specific descriptions of devil an diabolical beings which appear in the literary works and the iconography of that time. In our title, apart from devil, there is a mention to "diabolical beings". We use this expression in senso lato. According to our opinion "diabolical beings" are some characters as varied as pagans, jews, traitors, giants or some animals related to the diabolical world, as snakes and even monsters. Representations of devil and diabolical beings are studied through "genres" - that is to say in the differents forms of writing because each form of writing has different characteristics according to the "genres" and the audience

L'accroissement des debits dans les telecommunications actuelles precipite l'avenement de nouvelles technologies de multiplexage optique. Le multiplexage en longueur d'onde (wdm) parait prometteur mais repose encore sur des dispositifs peu mature comme les filtres spectraux accordables. Cette these a concerne l'etude theorique, la conception, la realisation pratique et les perspectives d'application et d'amelioration d'un filtre accordable etroit integre sur niobate de lithium et fonctionnant a une longueur d'onde proche de 1. 55 m. Nous comparons tout d'abord differents principes de filtres accordables integres et nous interessons tout particulierement aux dispositifs couplant deux ondes orthogonales. Puis, apres avoir retenu pour sa vitesse de commutation elevee un dispositif base sur l'effet electrooptique, nous decrivons son fonctionnement en prenant pour modele le filtre massif birefringent de solc. Ce modele simple nous permet de realiser de premiers filtres. Dans une troisieme partie nous etudions en detail la propagation de la lumiere dans notre systeme, decrit pour la circonstance comme un milieu heterogene tridimensionnel et anisotrope. Cette etude nous amene ensuite a rechercher dans le procede d'integration meme l'origine d'irregularites observees dans la transmittance du filtre. Ce travail s'accompagne, dans la quatrieme partie, d'une modelisation plus approfondie du filtre permettant de prendre en compte les defauts du processus technologique. Nous presentons alors des ameliorations de ce processus et de nouveaux filtres plus performants. Finalement, des applications systeme et des perspectives de developpement du dispositif sont presentees

Minerals bearers of elements of the rare (ETRs) lands in Albita Granite of Nucleus of the plúton Wood (mine of Pitinga) they were studied using analytical techniques for DRX, MEV and petrografica, having been accomplished structural geological mapping of the digging of the mine with the intention of evaluating the space distribution and structural control on the occurrence of dikes pegmatites and veins with fluorita. The analyses petrográficas were accomplished seeking to understand the mineral association and the processes put upon as deformation and/or alteration hydrothermal. Analyze them of diffraction of rays X (DRX) accomplished in the affected granite by process hydrothermal, that modified the texture and composition of the rock, to identify mineral argilo and minerals related to the event hydrothermal and with occurrence of elements rare (ETR) lands, and transition (ítrio) elements. The focus of the research consists of determining the style of occurrence of the minerals bearers of ETR and transition elements and the related minerals associations the these to understand the processes formators and to postulate a model that explains the presence of these minerals in the granite. The results of the research showed that mine accessory common in granites as zircon, apatite are accompanied of exotic minerals as, cryolite, xenotime, torite, riebeckite, pyrochlore and polilitionite, mainly of origin magmatic and late derived magmatic of the crystallization of two pulses discreet granitic, registering structure in banding compositional of flow magmatic that controls the space distribution of these mines, that exhibit organization and they link with minerals albita, K-feldspar and quartz, deformed for mechanisms developed in high temperature.

Dikes and veins spatially present pattern of compatible orientation with model of shearing guided dextral 260° and close dive of 60° for associated N her conjugated synthetic with attitude dominant close 110° dive of 70° for S and the structure tensile with close attitude of 340° and I dip subvertical for W. This model controlled the placement of the pluton, and the development of structures with occurrence of the minerals bearers of ETRs. The fluids rich hydrothermal in ETR percolated the albite granite and they generated argilo mineral product of the alteration of the same. The structural pattern and the identified mineral association, they attest the coherence with that the minerals bearers of ETRs are distributed in the albite nucleus granite.
Minerais portadores de elementos das terras raras (ETRs) no Albita Granito de Núcleo do plúton Madeira (mina de Pitinga) foram estudados usando técnicas analíticas por DRX, MEV e petrografica, tendo sido realizado mapeamento geológico estrutural da cava da mina com o intuito de avaliar a distribuição espacial e controle estrutural sobre a ocorrência de diques pegmatíticos e veios com fluorita. As análises petrográficas foram realizadas visando entender a associação mineral e os processos sobrepostos como deformação e/ou alteração hidrotermal. As analises de difração de raios X (DRX) realizadas no granito afetado por processo hidrotermal, que modificou a textura e composição da rocha, para identificar argilo minerais e minerais relacionados ao evento hidrotermal e com ocorrência de elementos terras raras (ETR), e elementos de transição (ítrio). O foco da pesquisa consiste em determinar o estilo de ocorrência dos minerais portadores de ETR e elementos de transição e as associações minerais relacionadas a estes para entender os processos formadores e postular um modelo que explique a presença destes minerais no granito. Os resultados da pesquisa mostraram que minerais acessórios comuns em granitos como zircão, apatita estão acompanhados de minerais exóticos como, criolita, xenotima, torita, riebeckita, pirocloro e polilitionita, principalmente de origem magmática e tarde magmática derivada da cristalização de dois pulsos graníticos discretos, registrando estrutura em bandamento composicional de fluxo magmático que controla a distribuição espacial destes minerais, que exibem organização e se relacionam com minerais albita, K-feldspato e quartzo, deformados por mecanismos desenvolvidos em alta temperatura. Fluido tarde magmático formou diques com textura pegmatítica e composição granítica, cujos minerais associam-se a zircão, criolita, xenotima, genthelvita, riebeckita, epidoto, pirocloro, gagarinita, polilitionita. Cresce que ocorreu Pulso de fluidos mais tardio constituído por cassiterita, torita e óxidos de ferro. E pulsos constituídos por fluorita, allanita, fluocerita, clorita e galena formando veios. Diques e veios espacialmente apresentam padrão de orientação compatível com modelo de cisalhamento dextral orientado 260° e mergulho próximo de 60° para N associado a conjugado sintético com atitude dominante 110° mergulho próximo de 70° para o S e a estrutura tensiva com atitude próxima de 340° e mergulho subvertical para W. Este modelo controlou a colocação do plúton, e o desenvolvimento de estruturas com ocorrência dos minerais portadores de ETRs. Os fluidos hidrotermais ricos em ETR percolaram o albita granito e geraram argilo minerais produto da alteração do mesmo. O padrão estrutural e a associação mineral identificada, atestam a coerência com que os minerais portadores de ETRs se distribuem no albita granito de núcleo.

La condensation a reflux intervient dans de nombreuses industries et permet de separer le composant le moins volatil des autres composes dans un melange de vapeur. Dans le but de reduire la consommation energetique, on utilise ce procede que l'on couple a une forte compacite du condenseur. Nous avons donc etudie le phenomene de reflux dans des canaux rectangulaires de faible diametre hydraulique. Ce mode de condensation ainsi que la geometrie presentent des particularites qui rendent delicat le dimensionnement des condenseurs. L'etude experimentale du phenomene d'engorgement en eau-air a contre-courant a montre que la repartition des debits dans un condenseur compact est aleatoire. Ainsi, l'engorgement n'est pas generalise a tous les canaux. Nous avons quantifie ce phenomene par deux correlations dependantes du debit d'eau qui simulent bien nos resultats experimentaux. La confrontation des donnees experimentales de la condensation de l'air humide a un modele fonde sur la theorie du film montre que les choix de nos correlations pour simuler les transferts de chaleur et de masse sont adaptes. Enfin, le reflux se manifeste en distinguant des zones preferentielles de condensation et des zones assechees ou depourvues de condensation.

Se pensiamo ad un generico punto sulla superficie terreste questo sarà soggetto allo spostamento nel tempo della propria posizione, a causa delle deformazioni della crosta terrestre. Se conosciamo l’intensità e la direzione dello spostamento possiamo esprimere la variazione delle coordinate del punto in un sistema di riferimento geodetico , in funzione del tempo. Varie teorie spiegano la causa di tali deformazioni crostali (ES. La Tettonica a Placche) , attribuendo l’origine a movimenti convettivi del mantello, determinati dalla variazione spaziale della densità ed al progressivo rilascio degli sforzi accumulati nella litosfera a causa del peso delle massi di ghiaccio che, hanno ricoperto parte della superficie terrestre nelle glaciazioni passate. Fin dagli anni’80 il GNSS è divento una tra le tecniche più idonee per andare a valutare lo spostamento della crosta terrestre rispetto ad un sistema di riferimento globale e regionale grazie all’elevato grado di precisione conseguibile.

Full textAbstract:
On etudie pour les larves d'un mollusque lamellibranche mytilus edulis l. , le role biologique des acides amines et du glucose dissous dans l'eau de mer. Le taux d'absorption des acides amines et du glucose augmente quand la larve passe de la phase endotrophe a la phase exotrophe. Au cours de ce passage, la part de molecules absorbee et utilisee a des fins energetiques croit, alors que celle participant a la croissance reste constante. La contribution energetique de chacune de ces substances est estimee a moins de 10% des besoins d'une larve de moule. Pour la phase endotrophe, l'action des acides amines sur la croissance embryonnaire et larvaire est variable, selon la nature et la teneur du substrat dans le milieu. L'effet favorable des acides amines se traduit par l'apparition de stades plus precoces pour les ufs, et par l'augmentation de la taille chez les larves. Pour la phase exotrophe, le glucose a 5,6 et 56 nmol/l favorise les taux de filtration et d'ingestion cellulaire de 20 et 26%, par rapport au milieu temoin. A 2,8 micromol/l, le glucose reduit ces taux de 18%. Par ailleurs, l'addition du glucose ou d'un melange d'acides amines a un regime d'algue (500 cell/larve) augmente la croissance en longueur et en poids sec des larves, par rapport au regime temoin. A 5000 cell/larve, l'addition de chacun de ces substrats n'a pas d'effet significatif sur la croissance en longueur des larves. Ces resultats ont permis de preciser et de replacer l'importance des acides amines et du glucose dans l'evolution trophique des larves de moule

Pour les technologies micro-electronique cmos 0. 25 micrometres et en dessous, l'isolement par tranchee peu profonde ou box s'est largement impose pour poursuivre l'integration des circuits integres. Ce procede d'isolement lateral, qui consiste a remplir d'oxyde une tranchee gravee dans le silicium du substrat, possede plusieurs avantages: une bonne planeite, une perte de cote nulle de la zone active du circuit, et une haute densite d'integration. Ces caracteristiques sont toutefois le resultat d'une optimisation delicate de chacune des etapes technologiques critiques du procede. De plus, la morphologie de l'isolement box induit l'existence d'un effet electrostatique parasite sur le fonctionnement des dispositifs du circuit. Nous avons montre que cet effet parasite, appele effet de coin, peut-etre reduit voir elimine grace a une optimisation du procede d'isolement. Enfin, l'isolement par tranchee peu profonde possede d'excellentes qualites pour l'isolation electrique des dispositifs dans un circuit cmos. En usant de ces proprietes, nous avons optimise l'architecture des caissons afin de reduire les capacites de jonction, et augmenter l'immunite au latchup des circuits, tout en conservant une isolation electrique parfaite entre les dispositifs du circuit

In questa tesi, sono esposti i sistemi di navigazione che si sono evoluti, parimenti con il progresso scientifico e tecnologico, dalle prime misurazioni della Terra, per opera della civiltà ellenica, circa 2.500 anni fa, sino ai moderni sistemi satellitari e ai mai tramontati sistemi di radionavigazione.
I sistemi di navigazione devono rispondere alla sempre maggiore richiesta di precisione, affidabilità, continuità e globalità del servizio, della società moderna. È sufficiente pensare che, attualmente, il solo traffico aereo civile fa volare 5 miliardi di passeggeri ogni anno, in oltre 60 milioni di voli e con un trasporto cargo di 85 milioni di tonnellate (ACI - World Airports Council International, 2012).
La quota di traffico marittimo mondiale delle merci, è stata pari a circa 650 milioni di TEU (twenty-foot equivalent unit - misura standard di volume nel trasporto dei container ISO, corrisponde a circa 40 metri cubi totali), nel solo anno 2013 (IAPH - International Association of Ports and Harbors, 2013).
Questi pochi, quanto significativi numeri, indicano una evidente necessità di “guidare” questo enorme flusso di aerei e navi in giro per il mondo, sempre in crescita, nella maniera più opportuna, tracciando le rotte adeguate e garantendo la sicurezza necessaria anche nelle fasi più delicate (decollo e atterraggio per gli aeroplani e manovre in porto per le grandi navi).
Nello sviluppo della tesi si proverà a capire quali e quanto i sistemi di navigazione possono assolvere al ruolo di “guida” del trasporto aereo e marittimo.

This study was designed to investigate the ultrastructural changes of mitochondria and mitochondrial DNA (mtDNA) mutations in human detrusor after partial bladder outlet obstruction (BOO). The correlation of these data with the results of urodynamic analysis was also studied. Fifty-two and sixty-two male patients with or without BOO were respectively enrolled in the ultrastructural study of mitochondria and the subsequent study of mtDNA mutations in the detrusor. The patients were assessed by international prostate symptom score (IPSS), quality of life assessment index (QoL) and sonography. The severity of partial BOO was determined by the urodynamic analysis with pressure-flow study and the pressure-flow data were plotted on the ICS-nomogram (international continence society-nomogram) and linPURR (linear passive urethral resistance relation) nomogram. In the first part of study, random detrusor biopsies obtained cystoscopically were fixed immediately and processed for transmission electron microscopic observation. Random areas were photographed for further morphological and morphometric analyses using mitochondrial damage score and stereological principles. Finally, We compared the ultrastructural data with urodynamic results statistically. In the second part of study, random detrusor biopsies obtained cystoscopically were analyzed by polymerase chain reaction (PCR) techniques to detect possible mtDNA deletions. Primer-shift PCR and DNA sequencing were then performed to characterize specific mtDNA deletion. A semi-quantitative PCR method was used to determine the proportion of the deleted mtDNA in detrusor. At last, the mtDNA deletion and the urodynamic results were compared statistically. In the first part of study, mitochondrial damage score and the mean volume of the mitochondria were found to correlate strongly with the urodynamic severity of partial BOO. Volume density of the mitochondria, surface density of the mitochondrial outer membrane and mitochondrial number per unit area of cytoplasm were not significantly correlated with the severity of partial BOO. In the second part of study, a 4,977 bp mtDNA deletion in the human detrusor was identified. Both the incidence and proportion of mtDNA with the 4,977 bp deletion were increased after partial BOO (P = 0.005 and P = 0.012, respectively). The incidences of the mtDNA deletion were 4.2% (1 of 24) in the non-obstructive group, 27.8% (5 of 18) in the equivocal group, and 40% (8 of 20) in the obstructive group. The mean proportions of the 4,977 bp deleted mtDNA were 23.7 and 12.7 times higher for the patients in the obstructive and equivocal groups, respectively, compared with that of the patients in the unobstructive group. We conclude that the swelling and structural destruction of the detrusor mitochondria were parallel to the severity of partial BOO. In addition, we first disclosed mtDNA with the 4,977 bp deletion in human detrusor and an increase of this mtDNA deletion after partial BOO. These changes might be associated with an impaired mitochondrial function and oxidative metabolism after partial BOO. The damage to the detrusor mitochondria and the increase of mtDNA deletion might account for the voiding dysfunction after partial BOO.

Full textAbstract:
This thesis presents a research on Vanth and Charun type demon depicted on relief urns from northern Etruria. The research focuses on urns from the Hellenistic period in Etruria (from the end of the 4th till 1st century BC). These urns were made in workshops in three Etruscan cities, which are now called Volterra, Chiusi and Perugia. The urns along with the centers of their production are described in one of the introductory chapters. Subsequently, the thesis focuses on a female demon Vanth and a male demon Charun, identified by their names inscribed on various media. Based on these, basic characteristics of these demons are evaluated and used as a basis for identification of demons on the relief urns in the database. The database is the core of the thesis. Its items are then classified by the production centers and the type of scenes that are in the reliefs on the front of the urns. Description of the urns is supplemented by pictures labeled with the names of the demons identified for a better representation. The data followed in the database are summarized in two analytical tables attached to the thesis. The database is evaluated in the last chapter and the appearance of demons and the attributes they hold in their hands are paid attention to. They are often related to the involvement of Vanth...

O Museu Arqueológico de São Miguel de Odrinhas alberga três sarcófagos etruscos, os únicos existentes em Portugal. Datados do século IV e III a.C., foram adquiridos no século XIX por Sir Francis Cook – então proprietário da Quinta de Monserrate, na serra de Sintra – que os utilizou como decorações nos jardins do seu palácio, denunciando assim o gosto que a Europa culta do Romantismo nutria por antiguidades e obras de arte de povos antigos e exóticos.
Ali permaneceram, tendo sofrido vários danos por parte de visitantes menos esclarecidos e das intempéries. A tampa com estátua jacente de um deles desapareceu numa noite de tempestade, em 1983. Finalmente, conseguiu-se a remoção destes monumentos para o Museu Arqueológico de São Miguel de Odrinhas.
Neste trabalho iremos procurar investigar o seu percurso desde a descoberta arqueológica até ao Museu, interpretando o contexto cultural que o condicionou, passando pela sua análise iconográfica e cronológica.The Archaeological Museum of São Miguel de Odrinhas holds within its walls three etruscan sarcophagi, the only ones in existence in Portugal. Dating back to the 4th and 3rd centuries bC, they were acquired in the 19th century by Sir Francis Cook – then the proprietor of the Farm of Monserrate, in Sintra – who used them as decoration in the gardens of his palace, as befits the taste that the cultured Europe of Romanticism entertained for antiquities and works of art belonging to ancient and exotic peoples. There they remained, having been damaged by the weather and unenlightened visitors. The sculpted lid of one of them disappeared in a stormy night of 1983. Eventually, they were removed and taken to the Archaeological Museum of São Miguel de Odrinhas.In this work we will attempt to investigate the history of their discovery and their subsequent journey, taking notice of the cultural contexts in which it took place, until finally reaching public display at a portuguese Museum. We will also include an iconographic and chronological approach.
