Abstract:
My project has been focused on the identification and validation of new mitochondrial gene variants and new mitochondria-related genes. The first report is about a woman presenting with a stroke-like episode and an history of severe hearing loss, frequent migraines, exercise intolerance, myalgias and limb-girdle muscle weakness indicating a slowly progressive myopathy and secondary amenorrhea with low gonadotropin levels. A muscle biopsy showed ragged-red, cytochrome c oxidase-negative fibers, and an isolated defect of cytochrome c oxidase activity in muscle mitochondria and sequence analysis of muscle mtDNA revealed a new heteroplasmic m.6597C>A transversion in the MTCOI gene, encoding subunit I of cytochrome c oxidase. Analysis on transmitochondrial cybrids demonstrated that the mutation is indeed associated with COX deficiency, i.e. pathogenic. The second report is about a new phenotype associated to mutations in the AARS2 gene encoding for the mitochondrial aminoacyl tRNA synthetase, identified in six patients presenting with primary ovarian failure, cerebellar and pyramidal signs and cognitive or behavioural disturbances. Two patients underlined a muscle biopsy which showed a severe complex IV defect at histochemical and biochemical analyses. The third report is about the clinical and biochemical phenotypes associated with mutations in two new mitochondrial aminoacyl tRNA synthetases (ARSs2) genes. In the first patient, an 8 years old child presenting with psychomotor delay, seizures, facial dysmorphisms and hyperlactacidemia and a brain MRI showing hyperintense lesions in the insula and fronto-temporal right cortex, whole exome sequencing (WES) identified a homozygous missense mutation in VARS2, encoding the mitochondrial valyl tRNA-synthetase. In two siblings presenting with a phenotype characterized by hypotonia and psychomotor retardation, high plasma and liquor lactate, both died at few months of age WES revealed two variants in TARS2, encoding the mitochondrial threonyl tRNA-synthetase: a missense and a splice site mutation. VARS2 and TARS2 mutations segregate within patients families. Patients’ clinical- biochemical phenotype and in silico and in vitro analyses of VARS2 and TARS2 mutations clearly indicate these genes as disease-causative. Expression of the corresponding wild-type enzymes led to recovery of the biochemical impairment of mitochondrial respiration in immortalized mutant fibroblasts; yeast modelling of the VARS2 mutation confirmed its pathogenic role.

Abstract:
Lung cancer arises from epithelial cells that line the air passages of the lungs. It is the second most common malignancy in the United States; trends suggest that over 228,000 new patients will be diagnosed with lung cancer in 2013. Due to the fact that lung cancer is highly aggressive, it has proven difficult to control. The 5-year survival rate has been shown to be only 15.9%, despite the advances made in terms of diagnosis and treatment. Therefore, we are faced with the problem of finding more effective methods that allow for an earlier diagnosis and the improved treatment of lung cancer. This study attempts to address these issues by investigating Tarsh, a novel molecule that is involved in the regulation of cellular senescence. Previous studies have shown that Tarsh is expressed in normal lung cells, but is significantly downregulated in lung tumors. These studies also determined that Tarsh is likely dependent upon the expression of p53, a tumor suppressor gene. The current study investigated these results, in addition to the biological effects of ectopically increasing Tarsh and/or knocking down p53 expression in two lung cancer cell lines: A549 and H1299 cell lines. It was determined that increasing the expression of Tarsh decreased the rate of proliferation in both cell lines. Additionally, it was shown that the knockdown of p53 increased proliferation in A549 cells. In regards to the migration rate of these cell lines, the overexpression of Tarsh decreased migration in A549 cells, but had no effect on H1299 cells. However, the role of p53 in migration is still unclear. The results of this study suggest that the knockdown of p53 decreases cell migration in A549 cells. This contradicts the fact that H1299 cells do not express p53, yet was found to have the highest migration rate. It is evident that a further investigation is needed to make more concrete conclusions. Nevertheless, the suppressive features of Tarsh on cell proliferation, and possibly migration, make it a promising target of research for lung cancer therapy.

Este estudo objetiva identificar a motivação para a emergência dos conflitos de natureza política na ekklesia de Corinto, logo após a sua fundação, em 50, por Paulo de Tarso. Destaca que as epístolas 1 e 2 Coríntios, redigidas por Paulo e endereçadas a essa comunidade entre 54-60, apresentam conflitos relacionados ao tipo de conduta adotado pelos membros e, sobretudo, a disputas por autoridade dentro da ekklesia, as quais se desdobram numa oposição à autoridade de Paulo como apóstolo. Na averiguação dos conflitos, faz uso de uma metodologia que se apoia na Análise de Conteúdo e nos pressupostos teóricos de Bourdieu acerca da eficácia do discurso e do poder simbólico, e assim investiga o grau de institucionalização do paleocristianismo e os modelos de autoridade apostólica vigentes no século I. Aponta como resultados que a autoridade de Paulo foi contestada porque os grupos paleocristãos não tinham uma referência única de autoridade e que o grau de institucionalização do paleocristianismo na metade do século I se mostrava incipiente, caracterizado pela ausência de fronteiras bem definidas entre os grupos religiosos de tendência judaico-cristã.

Abstract:
Cette recherche étudie les lettres de Paul de Tarse, telles que conservées dans le Nouveau Testament, dans le contexte des pratiques épistolaires antiques, principalement judéennes. L’interrogation initiale est double : d’une part, elle porte sur le potentiel documentaire offert par les sources de type épistolaire et, d’autre part, sur le potentiel pragmatique spécifique du médium épistolaire pour induire des changements chez les destinataires. Les lettres de Paul ont été écrites non pour consigner des réalités ou des vérités d’autrefois en tant que telles, mais pour communiquer efficacement auprès de cercles divers et variés de destinataires. Cette double interrogation est déployée en amont, parmi les pratiques susceptibles d’avoir servi de modèle, comme celle liée à la lettre aux exilés insérée narrativement dans le Livre du prophète Jérémie (chapitre 29). Celle-ci a servi de modèle de communication à distance pendant plusieurs siècles parmi différents milieux de la Diaspora judéenne. Est ensuite interrogée la pratique épistolaire de Paul lui-même, en particulier celle déployée dans sa IIe Lettre aux Corinthiens (chapitres 10-13). Cette séquence, écrite au moment d’une très forte remise en question de son autorité d’apôtre, montre bien le potentiel pragmatique que Paul reconnaissait au médium épistolaire, ceci en convoquant notamment l’autorité de Jérémie. Enfin, en aval, on s’intéresse aux débuts l’histoire de la réception de l’autorité d’épistolier de Paul. Celle-ci montre comment on a reconnu très tôt à l’apôtre Paul une autorité d’épistolier, à l’instar des prophètes écrivains de l’ancien Israël
This research examines the letters of Paul of Tarsus, as preserved in the New Testament within the context of letter writing of that time, principally Judean ones. The initial examination questions both the potential of sources such as letters to provide information about an era, and the specific pragmatic potential of the epistolary medium as a means of inducing change in its recipients. As such, the letters of Paul were written not to conserve the historical realities or truths of the past, but to communicate efficiently with diverse circles and various recipients. The two-part examination is used to gain a perspective on the practices of the time, which may have been used as models for epistolary writing. The letter addressing the Judean Diasporas exiles inserted into the narrative of the Book of Jeremy (chapter 29) is such a model, providing a means of communicating over distance and time among the different groups. The epistolary practice of Paul himself is then examined. In particular, his Second letter to Corinthians (chapters 10-13), written in a moment of intense self-examination as his apostolic authority was questioned, is a good example of the pragmatic potential that Paul recognised in the epistolary medium, particularly in light of the prophet Jeremy. Finally, the beginnings of the apostle Paul’s epistolary writing and it’s reception are explored, showing how his credibility as an apostolic authority was quickly and easily recognised as being of the same quality as those of the prophet writers of ancient Israel

Abstract:
Former manufactured gas plants (FMGPs) are a ubiquitous source of environmental con- tamination. The process of gas production created a number of by-products, including coal tar and ammoniacal liquor. Coal tar contains a complex mixture of organic and inorganic compounds, many of which are toxic and carcinogenic. It is estimated that over 3000±1000 FMGPs exist in the United Kingdom alone, yet there are few recent publications detailing the analysis of coal tars. The complex composition of coal tar is known to vary due to a number of factors, including production method, temperature and coal type, making the analysis and interpretation of such samples extremely challenging. Environmental forensics is concerned with the source, fate and transport of contaminants. The introduction of recent legislation such as the EU Environmental Liabilities Directive 2004/35/EC, which promotes the "polluters pay" policy, has encouraged the development of accurate and robust scientific methods for the identification of contaminants. Analytical instrumentation is constantly evolving, thus new protocols to trace the origin of contamination must also be developed to utilise these technological advances. Two-dimensional gas chromatography (GCxGC) and compound specific isotope analysis (CSIA) are two exam- ples of advanced analytical instruments which have the potential to aid source identification. GCxGC provides enhanced separation of complex mixtures compared to conventional gas chromatographic techniques, while CSIA allows chemically identical contaminants to be compared based on their isotopic composition. In this study, preliminary research investigated the isotopic composition of coal tars, as this technique is currently a major tool for source apportionment in environmental forensics. However, the results demonstrated .that the similar nature of British coals used for gas production at the investigated sites produced similar isotopic values in the resultant tars, making the technique redundant in this case. Therefore, the potential of GCxGC was investigated for ultra resolution chemical fingerprinting of coal tars. Traditionally, chemical fingerprinting of complex mixtures, such as coal tar, is performed using a tiered approach including rigorous sample preparation steps and analysis by multiple instruments. In this work, a new, single-step analytical procedure was developed for the analysis of coal tars by GCxGC. Automated sample extraction techniques combined with GCxGC analyses were employed to provide detailed chemical fingerprinting in a fast, yet accurate, manner. This research represents a major advance in knowledge of compositional variation within coal tars. The enhanced separation of GCxGC provides vast quantities of chemical data which can be difficult to interpret without statistical methods. A multivariate statistical model was developed to provide process-specific classification of coal tars. The statistical model was validated through use of a blind study, indicating that process-specific apportionment of coal tars was achievable. Based on these results, the application of the single-step procedure for environmental forensics on a commercial basis was evaluated.

Thesis (MMed (Surgical Sciences. Plastic and Reconstructive Surgery))--University of Stellenbosch, 2010.
The repair of full-thickness defects of the lower eyelids poses a challenge because a graft in combination with a flap is typically used to replace either the posterior or anterior lamella. This often results in aesthetically and functional unsatisfactory outcomes. A rotation-advancement tarso-conjunctival cheek flap, which reconstructs both posterior and anterior lamella with vascularized tissue similar to the native eyelid, is described. Nine patients underwent reconstruction with a rotation-advancement tarso-conjunctival cheek flap. The indications, complications and outcomes were evaluated. The follow-up time ranged from 6 to 60 months with an average of twenty three months. The main indication for use of this flap is full-thickness defects of the lower eyelid between 25 – 75 %, typically after tumour ablation. All the patients had a functional and aesthetically satisfactory outcome. One patient underwent a revision canthoplasty. The rotation-advancement tarso-conjunctival cheek flap adheres to basic plastic surgery principles resulting in a satisfactory outcome; (a) Vascularized tissue is used to reconstruct the defect. (b)The flap composition is similar to the native eyelid i.e. replace like with like. (c) The flap makes use of tissue that is excess and therefore limits donor morbidity.

Abstract:
A hanseníase é doença crônica causada pelo Mycobaterium leprae e possui como característica a alteração de sensibilidade cutânea, causando deformidades de mãos e pés. O tratamento compreende o uso de medicamentos (PQT) e o Ministério da Saúde (MS) preconiza o uso de palmilhas tipo Plataforma para Tarso (PT) como tratamento complementar. Há na literatura muitos artigos sobre o uso de palmilhas para melhora do equilíbrio e redistribuição da pressão plantar em pacientes neuropáticos, mas não foram encontrados estudos que incluíssem as palmilhas PT. Neste estudo comparou-se o equilíbrio do paciente hanseniano com valores de normalidade pré-definidos e também comparou-se prospectivamente a influência da palmilha PT no paciente com hanseníase, por meio de testes de equilíbrio estático e dinâmico realizados com o aparelho Balance Master (NeuroCom Int. Inc.) antes e após 3 meses de uso. Foram selecionados 40 pacientes em tratamento no HCFMRP, dos quais 19 mantiveram o seguimento à pesquisa (68,4% do sexo masculino, com média etária de 51,95), e todos com mesma classificação operacional Multibacilar. Os testes delinearam o comportamento destes pacientes com relação aos controles involuntário de equilíbrio (sistemas sensoriais-teste modifCTSIB) e voluntário de excursão do Centro de Gravidade Corporal (COG; teste LOS), bem como a estabilidade da marcha (teste WA). Os resultados obtidos com o modifCTSIB mostraram que os pacientes com hanseníase, para o controle do equilíbrio (de acordo com a relação entre testes com olhos abertos e fechados, e para superfície estável e instável; valor p<0,01 para todas as correlações aplicadas), são mais dependentes do sistema visual que do somatossensorial, em relação à normalidade. As palmilhas PT não influenciaram na modulação dos sistemas sensoriais (p>0,05). No entanto o uso das palmilhas interferiu negativamente no teste LOS, para as variáveis distância final percorrida e máxima excursão do COG somente no ponto para frente e para esquerda (p<0,01), e favoreceu o controle direcional do COG no mesmo ponto (p=0,02). Na análise dos prontuários foram identificados déficits sensitivos com maior frequência nos antepés esquerdos. O teste WA revelou que os pacientes apresentaram a marcha mais lenta em relação ao padrão de normalidade, e aumentaram a velocidade de marcha (p=0,04) e o comprimento do passo (p=0,04) após o uso das palmilhas. Concluiu-se que as palmilhas tipo PT favoreceram a estabilidade para a marcha e para o controle voluntário do equilíbrio. E ainda foi observado que os pacientes tornaram-se dependentes das palmilhas, fator importante a ser considerado pelo serviço de Saúde após a alta medicamentosa
Leprosy is a chronic disease caused by the Mycobacterium leprae with sensitivity impairment as a characteristic that could lead to deformities of hands and feet. The Ministry of Health of Brazil (MS) recommends the use of platform for Tarsus (PT) insoles as a complementary treatment to the Multi-drug Therapy (MDT). Many articles in literature discussed the use of insoles for improving balance and redistribution of plantar pressure in neuropathic patients, but there are no studies that included PT insoles. This study compared the balance control values for the leprosy patient with normal standards and also prospectively compared the influence of PT insole in patients with leprosy, by means of static and dynamic tests performed with the Balance Master (NeuroCom Int. Inc.) device, before and after 3 months. 40 patients following treatment in HCFMRP were selected, of which 19 completed the follow-up to the survey (68.4% male, mean age 51.95), all classified operationally as Multibacillary. The tests outlined the behavior of these patients with regard to involuntary balance control (modifCTSIB sensory test) and voluntary excursion of the Body Center of Gravity (COG; LOS test) as well as the gait stability (WA test). The results obtained with the modifCTSIB showed that patients with leprosy are more dependent on the visual system than the somatosensation for balance controlwhen compared to normal values (according to the relationship between tests with open and closed eyes, and stable and unstable surface; p <0.01 for all applied correlations). The insoles PT did not influence the modulation of the sensory systems (p> 0.05). However the use of insoles interfered negatively in the LOS test for the variables end point and maximum excursion of the COG only on the forward to left position (p <0.01), and favored the directional control of COG at the same position (p= 0.02). The analysis of the patients file revealed that sensitivity deficits were identified more frequently in the left forefeet, which might explain the observed differences for the excursion of the COG only in this region. The WA test showed that patients have slower walking patters compared to normal values but had their walking speed (p = 0.04) and the length of their step increased (p = 0.04) after the use of the insoles. It was concluded that the PT insoles favored gait stability and voluntary control of body balance. It was also observed that patients become dependent on the insoles, an important factor to be considered by the Health service after the PQT discharge

Une etude systematique de l'intercalation du mercure dans les disulfures de titane et de tantale a ete realisee. Elle a permis de preciser les conditions de synthese, la composition et la stabilite des produits. La resolution de la structure incommensurable de hg1,24tis2 par diffraction des rayons x sur poudre a mis en evidence la formation de chaines de mercure coordinnees par des canaux trigonaux prismatiques d'atomes de soufres. Grace a des mesures calorimetriques differentielles et de diffraction des rayons x en temperature, nous avons pu etudier la transition liquide-solide du mercure dans la lacune de van der waals. Ces memes methodes ont conduit a la presentation d'un diagramme de phases pour le systeme hg-tas2 precisant notamment les domaines d'existence de deux phases notees alpha et beta. Les interactions particulieres du mercure avec les structures d'accueil ont ete sondees par des techniques physiques telles que xanes, xps, eels. L'interpretation des resultats obtenus a ete effectuee d'une part grace a l'emploi de composes modeles comme les intercalaires au lithium et, d'autre part, grace a une tres large utilisation de calculs de structures de bandes par la methode de huckel etendue.

Abstract:
The Crioulo horse industry has increased exponentially in the last few years, this scenario, leads horse breeders to neglect individual aspects of the horse s development, interfering, mostly, in the nutritional management, as younger animals are participating in halter shows. These changes in horse management without considering individual aspects of growth, feeding and exercise level predispose these animals to the complex of diseases known as developmental orthopedic diseases. Radiographs were taken of both tarsi of 77 (31 fillies and 46 colts), of nine up to 26 months old Crioulo horses, competing or not in halter events. These young horses were divided in groups by age, with one including nine to 18 months old foals (G1) (34/77) and the other 19 to 26 months old ones (G2) (43/77). According to preparation or not for halter competition, horses were divided into GI (48/77) (average preparation time 4.55 months) and GC (control group, 29/77), respectively. Data were collected on 24 breeding farms or training centers, to determine the prevalence of osteoarticular changes. The results showed that 77.22% (61/77) presented some degree of radiographically visible lesions. The prevalence of lesions in males was 80.44%, 77.42% in females; 77.31% in the GC; 79.17% in the GI; 86.67% in G1 and 76.75% in G2. The mean body weight of the 10 to 12 month old yearlings (G1) was 293.25kg, representing 71.28% of the mature weight and that of the 19 to 26 month old ones (G2) was 360.5kg (87.71% of mature weight), the mean body weight of GC was 288.9kg (70.22% of the mature weight), and that of GI was 341.9kg (83.11% of the mature weight), even with the mean age of both groups being 16.79 and 18.98 months, respectively. A significant relationship was found between the animal s weight gain (p= 0.02; r= 0.26), body condition score (p= 0.03; r= 0.23), neck crest score (p= 0.018; r= 0.27) and wither s height (p= 0.01; r= 0.28) and the degree of the radiographic lesions found in the tarsi. Several factors can be involved in distal tarsal juvenile osteoarthritis; however the most important factor present in Crioulo breeding farms was the horse s overweight.
O comércio do cavalo Crioulo tem crescido de forma exponencial nos últimos anos, este cenário de valorização dos animais desta raça induz os proprietários e criadores a interferirem profundamente no manejo, principalmente nutricional, destes animais, decorrente da participação de potros e animais adultos em exposições e competições morfológicas. A interferência no manejo dos animais não levando em conta os aspectos individuais do desenvolvimento, sem controle exato da alimentação fornecida e do nível de exercício exigido predispõem os animais ao complexo de doenças conhecido como doenças ortopédicas do desenvolvimento. Foram examinados radiograficamente os tarsos de 77 animais (31 fêmeas e 46 machos), com nove até 26 meses de idade, participantes ou não de exposições ou competições morfológicas. Os animais foram divididos em grupos por idade, um incluindo potros de nove a 18 meses (G1) (34/77) e outro com animais de 19 a 26 meses (G2) (43/77), e pelo tempo de preparo para exposição morfológica em grupo controle (GC) (29/77) (sem preparo para exposição) e grupo incentivo (GI) (48/77), com preparo médio de 4,55 meses. Os dados foram coletados em 24 propriedades de criação ou centros de treinamento/preparo, para determinar a prevalência de alterações osteoarticulares. Observou-se que 77,22% (61/77) apresentaram alguma lesão radiograficamente visível. A prevalência de lesões articulares foi de 80,44% nos machos, 77,42% nas fêmeas, 77,31% nos animais do GC, 79,17% dos animais do GI, 86,67% nos animais do G1 e 76,75% nos animais do G2. O peso médio aos 10 a 12 meses de idade foi de 293,25kg, representando 71,28% do peso adulto e dos animais com idade de 19 a 26 meses o peso médio foi de 360,5kg (87,62% do peso adulto), nos animais do GC o peso médio foi de 288,9kg (70,22% do peso adulto) e os animais do GI apresentaram peso médio de 341,9kg (83,11% do peso adulto), mesmo a idade média dos dois últimos grupos tendo sido de 16,79 meses e 18,98 meses respectivamente. Foi constatada relação entre o aumento do peso dos animais (p= 0,02; r= 0,26), do escore corporal (p= 0,03; r= 0,23), do escore de deposição de gordura na crista do pescoço (p= 0,018; r= 0,27) e da altura (p= 0,01; r= 0,28) com as lesões radiográficas no tarso dos potros. Vários fatores podem estar envolvidos na osteoartrite társica distal, entretanto, o fator mais importante presente nas criações de cavalos Crioulos, é o sobrepeso.

Essa tese examina os evangelhos e as cartas do Novo Testamento como fontes documentais na busca por construir uma história da importância das mulheres para o estabelecimento bem sucedido da Igreja nos séculos I e II na Palestina e na Diáspora romanas enquanto ainda era identificado como um movimento religioso judaico. Inicia-se essa pesquisa pela obervação do contexto social e cultural mais abrangente da formação do mediterrâneo greco-romano e suas atitudes para com o feminino a partir da análise de escritos dos seus pensadores, historiadores, poetas e filósofos, expondo sua misoginia de estado e suas preocupações pela preservação de valores e tradições religiosas de sua sociedade patriarcal. No capítulo dois procura-se uma aproximação mais acurada do contexto da Judéis do primeiro século onde nasce o movimento que deu origem ao cristianismo e a atitude geral para com as mulheres, observando-se como o sincretismo cultural e religioso que reuniu tradições das culturas presentes na formação do pensamento religioso israelita e judaica influenciaou sua percepção sobre o feminino. Os capítulos três, quatro e cinco são dedicados à observação dos movimentos de Jesus e de Paulo com a peculiar e marcane presença de mulheres que tiveram participação chave para o sucesso do estabelecimento da Igreja ocupando posições de autoridade e as várias formas como sua importância foi diminuída ou apagada dos textos bíblicos e da história por uma processo não natural. Na conclusão se ressalta a realidade e a importância fundamental da mulher ocupando cargos de liderança nos cultos e no sacerdócio antes percebidos como lugares de homens, desde a fundação das comunidades cristãs, não sem incômodr sua sociedade patriarcal. Fica claro que as mulheres tiveram muita liberdade de atuação no movimento de Jesus e recebiam dele tratamento diferencial em relação à atitude geral para com elas. Paulo a principio segue essa mesma atitude para com as mulheres para em algum momento de seu ministério aderir à forma misógina de sua sociedade e estabelecer os primeiros conceitos teológicos que viriam a fundamentar os argumentos necessários para a transformação do cristianismo numa das instituições mais misóginas da história da humanidade.
This thesis examines the Gospels and the New Testament texts as documentary sources in the construction of a history about the importance of women for the successful establishment of the Church in the first and second centuries in Palestine and the Roman Diaspora while still identified as a Jewis movement. The research begins by the observation of broader social and cultural context of the formation of the Graecco-Roman Mediterran and their attitudes toward the female from the analysis of its thinkers, historians, poets and philosophers texts, exposing its state of misogyny and their concerns for the preservation of values and religious traditions of their patriarchal society. Chapter two focuses on a more accurate approximation of the context of first century Judaea where starts the movement that gave rise to Christianity and its general attitude towards women, observing the cultural and religious syncretism that gathered traditions of many cultures in the formation of the Israeli and Jewish religious thought that influenced their perception of the female. Chapters three, four and five are dedicated to the observation of the movements of Jesus and Paul with the peculiar and clear presence of women who had key contribution to the success of Church's establishment occupying positions of authority and various forms as its importance was diminished or deleted from biblical texts and history by an unnatural process. In conclusion it underscores the reality and the real importance of women occupying leadership positions in the services and the priesthood before perceived as places of men from the foundation of the Christian communities, not without distubing the patriarchal society. It is clear that women have a lot of freedom of action in the Jesus movement and received his differential treatment in the general attitud toward them. Paul at first follows the same attitud towards women to at some point in his ministry to join the misogynist form of his society and establish the first theological concepts that would substantiate the arguments necessary for the transformation of Christianity in the most misogynistic institutions in the history of humanity.

Paul de Tarse est-il le "Père" de la pratique épistolaire chrétienne? Après avoir inscrit sa pratique dans le contexte épistolaire de l'Antiquité et l'avoir évaluée à l'aune de l'analyse rhétorique qui domine actuellement dans le champ des études pauliniennes, cette thèse propose, dans un premier temps, un modèle de son énonciation épistolaire construit à partir d'une analyse littéraire de ses écrits et s'appuyant sur les théories de l'énonciation. Ensuite, elle le rapproche des épîtres pseudépigraphiques attribuées à Paul pour montrer que l'apôtre n'est pas imité par ses successeurs eux-mêmes. Enfin, elle le confronte aux autres épîtres du Nouveau Testament ainsi qu'aux épîtres des Pères apostoliques pour conclure que la pratique épistolaire paulinienne ne fut qu'une actualisation particulière des potentialités de la lettre antique et qu'elle entre en concurrence avec d'autres pratiques : la pratique antique continuée et une nouvelle pratique chrétienne, la "lettre mémoriale"
Was Paul of Tarsus the "father" of the Christian epistolary praxis? After inscribing his praxis in the epitolary framework of Antiquity and checking it against the rhetorical analysis widespread in the field of the Pauline studies, this Ph. D. Put first forward a model of his epistolary utterance built from a literary analysis of his letters, which rely on the enunciation theories. It compares subsequently Paul's letters to the pseudepigraphical epistles attributed to the apostle : it proves that Paul was not followed, even by his own successors. It relates finally the model to the other epistles of the New Testament and to the epistles of the Apostolic Fathers and concludes that the Pauline epistolary praxis was only a realization of the potentiality of the ancient letter and was in competition with other praxis : the continuation of the ancient praxis and another Christian praxis, the "memorial-letter"

Freud nombra al problema de la culpa en la cultura como “malestar”. La conciencia de una culpa, en donde somos culpables incluso antes de ser juzgados como tales. El discurso psicoanalítico, el jurídico y el teológico se cruzan ante el tema de la culpabilidad. Lo puesto en cuestión es la ley. Solo recordar la frase freudiana de que el más inocente de los hombres es el que más se tortura por dentro. Lo que lo tortura es la ley, una continua observancia a la ley. Aquella ley imposible, que Pablo la designa como maldición. Ley y castigo, ya que solo se observa la ley en función de un castigo futuro inminente. ¿Cómo reaccionar ante esta ley? Se trata de la violencia. El criminal o es criminal por que ejerce violencia ante la ley, transgresión, o por que ha dejado que esta ejerza violencia en él. Esta última solo demuestra la naturaleza paradójica de la ley, de una ley rigurosa que actúa de forma negativa, ya que no hay inocentes frente a la ley. Una acción positiva, reclama el castigo de la ley y que constituya a los justos como culpables. Si los justos son culpables, y se le exige a la ley que sea ella ahora la injusta, se trata de precipitar la anomía y hacer posible un nuevo estado de excepción, un real estado de excepción, no soberano, por que el soberano no está encima de la ley, sino que ha sido colgado en la cruz por ella. El sacrificio hace posible la katargein, esto es, la de-activación de toda ley.

Abstract:
Gasification of biomass will likely play an important role in the production of energy and chemicals in a future sustainable society. However, during gasification impurities, such as tars, will be formed. Tars may cause fouling and blockages of equipment downstream the gasifier. It is therefore important to minimize the formation of tars, alternatively to remove the formed tars. These processes need to be monitored, which makes it necessary to develop tar analysis methods suitable for this task. This work describes the development of two tar analysis methods, an on-line method based on a photoionization detector (PID) and an off-line method based on solid phase microextraction (SPME). Both methods were successfully validated against the established solid phase adsorption (SPA) method. The method based on PID was shown to have a very fast response time. Furthermore, the PID method is selective towards tar, but only limited information will be obtained regarding the composition of the tar compounds. The PID method is suitable for applications where it is important to detect fast changes of the tar concentration, i.e. process monitoring. The SPME method was shown to be a very sensitive method for qualitative and quantitative tar analysis. The sampling temperature was shown to be crucial for obtaining analysis results with the wanted detection limit. The SPME method is suitable for applications where extremely low detection and quantification limits are needed, i.e. for syngas production.

Abstract:
In this study, several techniques were applied in order to produce PolyHIPE Polymer (PHP) with improved morphology and properties. Several types of PolyHIPE Polymers (PHPs), silica, vinyl trimethoxy silane (VTMS), and VTMS-silica PHPs, were successfully produced and compared to basic PHPs. The VTMS-silica PHP produced has the highest surface area, followed by silica-PHP and then by VTMS- PHP when compared to typical (basic) PHP. For VTMS PHP, only PHPs with 30, 35 and 40% VTMS exhibit higher surface area than basic PHP. There was no improvement of surface area for PHP with VTMS percentage lower than 30%. All VTMS-silica PHPs have higher pore volume of all types of modified PHPs. The highest pore volume was observed for S30B30, the PHP with 30% VTMS in the oil phase and 30% silica in the aqueous phase. VTMS PHPs with VTMS percentage of 20% and above and silica PHP with 30 % silica have significantly higher pore volume than basic PHP. None of the PHPs showed the existence of micropore volume. Silica and VTMS were successfully reinforced into the HIPE producing novel PHP. This was confirmed by the results produced through FTIR spectroscopy and EDX (Energy Dispersive X-Ray) analysis. Novelty was observed in the morphology of VTMS and VTMS-silica PHP whereas silica-PHP retained the typical morphology of PolyHIPE polymer. The novel morphology of banana-like strands with coral-like pore was produced due to functionalising of VTMS to the HIPE through VTMS incorporation in the oil phase. VTMS-silica PHP is best described as having morphology of knobbly structure produced through incorporation of silica CC30 solution through aqueous phase with VTMS through oil phase. Sulphonated silica-PHP was successfully produced through microwave irradiation and thermal treatment whereas sulphonated-VTMS PHP was successfully produced through thermal treatment only. The sulphonation process decreased the surface area of silica and VTMS PHPs significantly. There was no significant difference between the pore volumes of silica PHPs and those of sulphonated silica PHPs whereas pore volumes of VTMS PHPs decreased significantly due to sulphonation. The sulphonation process retained the morphology of silica and VTMS PHPs except for minor cracks. The project also involved a study on tar removal/conversion using the modified PHP developed in the laboratory, high voltage and non-thermal plasma technique, specifically dielectric barrier discharge. The PHPs combined with dielectric barrier discharge was applied in the fine cleaning system. Due to complexity of the crude oil used as the tar model, no valid conclusion could be made about the tar removal or conversion. However, important positive effects from the treatment were observed in the removal of model tar from the model syngas under electric field or non-thermal plasma.

Abstract:
Determinations of design parameters and investigation on operation performance of a tar removal system for gas cleaning of biomass producer gas have been undertaken. The presence of the tars in the producer gas has been the major hindrance for the commercialisation of the biomass gasification technology for power generation, hydrogen production, Fischer Tropsch (FT) synthesis, chemical synthesis and synthetic natural gas (SNG) synthesis. The characteristic of the tars to condense at reduced temperatures cause problems in the downstream processing as the tars can block and foul the downstream process equipment such as gas engines reactor channels, fuel cells, etc. Considerable efforts have been directed at the removal of tars from the producer gas where the tars can be either chemically converted into lighter molecular weight molecules or physically transferred from gas phase to liquid or solid phase. In the former, the tars have been removed in a scrubber by transferring them from the producer gas to a scrubbing liquid and then removed from the liquid to air in a stripper and finally recycled them into air to a gasifier to recover their energy. A tar removal test system involving a scrubber and stripper has been designed based on the predicted tar solubility in canola methyl ester (CME) as the scrubbing liquid and its measured properties (CME is a type of methyl ester biodiesel). The tar solubility has been predicted to decrease with increasing temperatures and thus its value increases at lower temperatures. In designing the test system, the design parameters are needed including equilibrium coefficients of the gas-liquid system, molar transfer coefficient and the optimum liquid to gas flow rate ratio. The equilibrium coefficients have been predicted based on thermodynamic theories where the required data are determined from CME composition and known properties of each component of the CME as well as the properties of the model tar (naphthalene). The molar transfer coefficients are then experimentally determined and the correlations as a function of liquid and gas flow rates are proposed which are consistent with literature. The optimum liquid to gas flow rate ratios have been found to be 21.4±0.1 for the scrubber and 5.7±0.1 for the stripper. Using these optimum ratios, the tar removal efficiencies in the scrubber and the stripper are 77 and 74%, respectively. The analysis of the system performance has been achieved after an innovative method of determining tar concentrations in both the liquid and gas phase had been developed based on the concept of the density of liquid mixtures. However, these tar removal efficiencies are low due to the fact that the targeted tar concentration in the scrubber’s off-gas was large. As a result the system has been redesigned based on the determined design parameters and its operation performance retested. In the redesigned system, the tar removal efficiency in the scrubber and stripper is 99%. The redesigned system would be integrated with the UC gasifier for downstream gas cleaning. Since 1% of tars are not removed, a makeup tar free CME of 0.0375 litres per hour for the 100kW UC gasifier has been introduced in the recycle stream between the scrubber and stripper to avoid tar accumulation in the system.

Para isto, realizamos uma pesquisa bibliográfica a partir das obras deste filósofo da educação nas quais encontramos suas principais idéias acerca do uso da argumentação e da análise retórica. Logo, consideramos desde o capítulo Estatuto de cientificidade da pedagogia, publicado pela primeira vez em 1996, até (inclusive) a publicação, em 2008, do livro Doutrinas pedagógicas, máquinas produtoras de litígios. Enquanto o primeiro capítulo desta dissertação descreve as referidas idéias, o segundo capítulo analisa três pontos que permeiam as idéias apresentadas no capítulo anterior: a organização das teorias pedagógicas em torno de metáforas, o processo de validação das teorias pedagógicas, e a função e os limites da análise retórica aplicada às teorias pedagógicas. Na conclusão, convencidos de que o objetivo desta pesquisa tenha sido alcançado, apresentamos a utilidade do processo argumentativo e a necessidade da consideração da análise retórica como um dos instrumentos para a crítica das teorias pedagógicas.
This dissertation aims to describe and analysis the use of argumentation and rhetorical analysis for the development, critique and comprehension of pedagogical theories, focusing on the work of Tarso Mazzotti. Bibliographical research was undertaken, concentrating on the work of this philosopher of education and his principal ideas on the use of argumentation and rhetorical analysis. The texts analysed range from The scientific status of pedagogy, originally published in 1996, to the publication, in 2008, of his book Pedagogical doctrines: dispute-producing machines. The first chapter of this dissertation describes the central ideas, while the second chapter analyses three central aspects of the ideas presented in the previous chapter: the organization of pedagogical theories around metaphors; the validation process of pedagogical theories; and the function and limits of rhetorical analysis applied to pedagogical theories. The conclusion reinforces the utility of argumentative processes and the need to consider rhetorical analysis as one of the instruments for the critique of pedagogical theories.

Abstract:
The interplay between different self-organized electronically ordered states and their relation to unconventional electronic properties like superconductivity constitutes one of the most exciting challenges of modern condensed matter physics. In the present thesis this issue is thoroughly investigated for the prototypical layered material 1T-TaS2 both experimentally and theoretically. At first the static charge density wave order in 1T-TaS2 is investigated as a function of pressure and temperature by means of X-ray diffraction. These data indeed reveal that the superconductivity in this material coexists with an inhomogeneous charge density wave on a macroscopic scale in real space. This result is fundamentally different from a previously proposed separation of superconducting and insulating regions in real space. Furthermore, the X-ray diffraction data uncover the important role of interlayer correlations in 1T-TaS2. Based on the detailed insights into the charge density wave structure obtained by the X-ray diffraction experiments, density functional theory models are deduced in order to describe the electronic structure of 1T-TaS2 in the second part of this thesis. As opposed to most previous studies, these calculations take the three-dimensional character of the charge density wave into account. Indeed the electronic structure calculations uncover complex orbital textures, which are interwoven with the charge density wave order and cause dramatic differences in the electronic structure depending on the alignment of the orbitals between neighboring layers. Furthermore, it is demonstrated that these orbital-mediated effects provide a route to drive semiconductor-to-metal transitions with technologically pertinent gaps and on ultrafast timescales. These results are particularly relevant for the ongoing development of novel, miniaturized and ultrafast devices based on layered transition metal dichalcogenides. The discovery of orbital textures also helps to explain a number of long-standing puzzles concerning the electronic self-organization in 1T-TaS2 : the ultrafast response to optical excitations, the high sensitivity to pressure as well as a mysterious commensurate phase that is commonly thought to be a special phase a so-called “Mott phase” and that is not found in any other isostructural modification.

Que prescrivait-on aux eleves et qu'attendait-on d'eux ? quels objectifs didactiques etaient assignes a chaque exercice ? a la lumiere de ces questions, les progymnasmata apparaissent comme un instrument d'enseignement debordant largement le cadre de la rhetorique : ils comportent un apprentissage linguistique propre, indispensable a une epoque ou l'ecart s'est creuse entre la langue parlee et celle des ecrits et discours ; ils sont egalement associes a un programme complet d'etudes litteraires. Les exercices preparatoires oeuvrent ainsi efficacement a la transmission de la langue et de la culture grecques classiques.

Abstract:
L'Europe est confrontée à des défis climatiques et énergétiques et vise à accroître l'utilisation de la biomasse dans la production d'énergies renouvelables. De nombreuses difficultés technologiques persistent, par exemple, la gazéification de la biomasse produit un gaz de synthèse riche en goudrons et H2S qui peuvent conduire à une désactivation des catalyseurs dans les réacteurs en aval. Notre objectif a été de développer des catalyseurs stables qui peuvent réformer complètement ces hydrocarbures contenus dans le gaz de synthèse. Des nanoparticules de nickel encapsulées dans des monocristaux de silicalite-1 creusée formant une cavité unique ("single-hollow") ont été étudiées. L'encapsulation a pour but de limiter le frittage des particules et le cokage dans des conditions de reformage difficiles. Le frittage de ces particules au sein de chaque monocristal a cependant été observé. La synthèse d'une nouvelle structure creusée (c'est-à-dire un monocristal de zéolites avec de multiples cavités mésoporeuses, nommé "multi-hollow") a été développée. L'exclusion en taille de composés aromatiques larges par la membrane l'échantillon a été démontré. Ce matériau a également permis d'améliorer la dispersion initiale des nanoparticules métalliques. L'activité de l'échantillon a cependant été affectée par deux facteurs principaux associés aux étapes de préparation, c'està- dire la formation d'une couche de silice à la surface des particules et d'un empoisonnement au phosphore. Au cours du réformage d'un gaz de synthèse model riche en hydrocarbures, la membrane silicalite-1 n'a pu empêcher la désactivation due aux goudrons des particules de nickel encapsulées, car ceux-ci craquent aux températures typiques de reformage en composés aromatiques plus petits, susceptibles de se diffuser à travers la paroi de type MFI. La préparation de matériaux analogues à base de Rh n'a pas pu être réalisée. Des catalyseurs à base de Rh et de Ni supportés sur alumine ont ensuite été testés. Nous avons montré que le H2S induit une chute significative de l'activité en reformage et que les catalyseurs au Rh sont les moins influencés par le cokage et l'empoisonnement au S. L'activité en reformage du méthane était proportionnelle à la surface spécifique en Rh. Une température de réaction élevée (> 875 °C) a été jugée nécessaire pour limiter la désactivation par cokage
Europe is facing climate and energy challenges and aims at increasing the utilization of biomass in the production of renewable fuels. Many technological difficulties remain, for instance, biomass gasification produces a syngas rich in tars and H2S that can lead to catalyst poisoning in downstream reactors. Our goal was to develop stable catalysts that could fully reform producer gas. Nickel nanoparticles encapsulated inside hollow silicalite-1 single crystals were studied. The encapsulation was expected to limit particle sintering and coking under harsh reforming conditions. These particles could still sinter within each single crystal. The synthesis of a novel hollow structure ("multi-hollow", i.e. a single zeolite crystal with multiple mesoporous cavities) was developed. The size-exclusion of large aromatic compounds from the sample was demonstrated. This material also enabled improving the initial dispersion of metal nanoparticles. The sample activity was yet adversely affected by two main factors associated with the preparation steps, i.e. the formation of a silica over-layer and phosphorus-poisoning. During the reforming of a simulated producer gas, the silicalite-1 membrane could not prevent tar-related deactivation of embedded nickel particles, because those were cracked at typical reforming temperatures into smaller aromatic compounds, which could diffuse throughout the MFI-type layer. The preparation of Rh-based multi-hollow analogues could not be achieved. Alumina-supported Rh and Ni-based catalysts were then tested. H2S induced a large drop of the reforming activity and Rh catalysts were the least impacted by coking and S-poisoning. Methane reforming rate were proportional to the Rh metal surface area. The use of high reaction temperatures (>875°C) was shown to be necessary to limit deactivation by coking

Abstract:
O objetivo central deste artigo é identificar quais entraves culturais e burocráticos impactaram o processo de implantação da política de transparência no estado do Rio Grande do Sul no período de 2011 a 2014, considerando a trajetória nacional de desenvolvimento da transparência. A dimensão instrumental da transparência ao regime democrático permite a ampliação dos mecanismos de acesso às informações públicas, com a finalidade de consecução dos mecanismos de accountability. A transparência é uma estratégia de diminuição do segredo e do obscuro no quotidiano estatal. Essa circunstância pretende possibilitar que os governos sejam mais responsáveis frente aos cidadãos. Assim, a cultura da transparência entra em disputa com a cultura do segredo, uma vez que, para o seu desenvolvimento, há necessidade de interferir nas relações de poder consolidadas dentro da estrutura estatal. A análise dos entraves à execução da política de transparência decorre da experiência empírica como gestora da política de transparência no RS. Por fim, as mudanças geram resistências, interferindo no resultado final da implementação da política de transparência. Esses resultados não decorrem, exclusivamente, da vontade política do governante ou da força de resistência da burocracia, mas, precisamente, da relação de força entre eles.
This study aims to identify which cultural and bureaucratic obstacles affected the process of implementing the transparency policy in the state of Rio Grande do Sul, Brazil, in the period of 2011-2014, taking into account the national trajectory of the development of transparency. The instrumental dimension of transparency to the democratic regime allows the expansion of the mechanisms that grant access to public information in order to achieve accountability mechanisms. Transparency is a strategy to dwindle the secrecy and obscurity of the state’s daily life; it aims at making governments more accountable to their citizens. Thus, the culture of transparency is in dispute with the culture of secrecy, since there is a need to interfere in the consolidated power relations within the state structure for transparency to flourish. The analysis of the obstacles to the implementation of the transparency policy stems from my empirical experience as manager of the transparency policy in Rio Grande do Sul. Finally, the changes generate resistance, interfering in the outcome of the implementation of the transparency policy. These results do not derive exclusively from the political will of the ruler or from the resistance force of the bureaucracy, but precisely from the relation of force between them.

O desenvolvimento desta pesquisa faz parte dos projetos da Pós-Graduação em Geoquímica: Petróleo e Meio Ambiente – POSPETRO e está contemplada no âmbito da Rede Cooperativa em Recuperação de Áreas Contaminadas por Atividades Petrolíferas - RECUPETRO, estabelecida pelo Núcleo de Estudos Ambientais do Instituto de Geociênicas da Universidade Federal da Bahia - NEA/IGEO/UFBA. Nesta pesquisa, se fez um estudo teórico dos aspectos físico-geoquímicos dos asfaltenos e, do processo e informações geradas a partir da hidropirólise de asfaltenos. Além disso, este estudo avaliou o processo de separação e de limpeza dos asfaltenos obtidos a partir de duas amostras de arenitos impregnados de óleos (um arenito betuminoso da Fm. Parambóia da Bacia do Paraná e um arenito impregnado de óleo degradado da Fm. Ilhas ou Candeias da Bacia do Recôncavo). A geoquímica de asfaltenos permite obter informações correlacionáveis com as geradas em condições naturais, por uma rocha geradora, devido à semelhança geoquímica dos asfaltenos com o querogênio. A hidropirólise de asfaltenos é uma técnica de oxidação térmica usada amplamente em estudos geoquímicos para procurar entender os processos, reações e composições das estruturas complexas, como são os asfaltenos. As substâncias geradas durante o processo hidropirolítico servem para avaliar os parâmetros geoquímicos do óleo original e para definir estretégias tecnológicas e ambientais que melhorem a industrialização e manuseio de óleos com elevado conteúdo de asfalteno.

Abstract:
This project considers profane moments in three Middle English texts which use an incongruous combination of religious elements and exaggerated misbehavior to entertain the reader, as well as to critique, question, or mock established values and their all-too-human representatives. Each text draws its form from popular, entertaining genres, yet inserts learned and pious elements. The resulting collisions of cultural registers including high and low, sacred and profane, create ludic and layered explorations of those categories. In each text, undercurrents of incongruity and inversion blur, invert, or exaggerate the shocking or entertaining effect of bad behavior. I read this combination of contrasting influences as a carnivalesque and at times subversive form of social commentary, and suggest that both the popularity and the religiosity of each text are key to its provocative incongruity. In addition to the transgressive elements that knowingly elicit a strong audience reaction, each text has its unintentionally offensive aspects— passages likely be read differently by readers today than in the fourteenth century. In each chapter, I consider some of the pedagogical challenges and opportunities afforded by not only aesthetically but ideologically shocking elements, and the tensions these moments stand to expose in both their medieval context and the contemporary literature classroom. My approach combines cultural studies and pedagogy to ask how abstract hierarchies of low and high, profane and sacred, can be explored through the use of these entertaining, yet challenging, texts in a college classroom setting, using moments of exaggerated transgression to generate practical approaches to discussion with students.

The subject celestial journey , well familiar to the old mediterranean world, is based on the belief that the visionary can cross the boundary between humanity and divinity, a constant characteristic in apocalyptic literature. Old Jewish mysticism was seen as an important dimension of this tradition, that is the reason why the mystics used the term apocalypse to describe the revelation of their experiences. Paul s ascension to heaven, recounted in 2 Cor 12,1-10, is the only first hand account and the best evidence of ecstatic practice of celestial journey in first century Judaism. This text, one of great interest in the studies of New Testament, has been examined in thematic forms that extend from the recognition of the apostle as enjoyable to divinity - what granted him such a heroic achievement - to a punishment experience by the guardians of the celestial gates for finding in him no merit to approach the place of the presence of God. For long time, the studies that prevailed in the academy were those of the theological aspects of the passage, such as the spine in the flesh , the apostolic mission , Paul s opponents , among others. The language of the passage reveals important topics that were not considered together for a coherent interpretation of the text. The use of expressions from the Jewish mystical apocalyptic circle like "caught up", "Third Heaven", "hear unutterable words" and "a thorn for the flesh" by the apostle needs to be investigated for the comprehension of what Paul had in mind while using those terms. Another problem is the omission of the experimental approach described in the passage. The apostle reveals that he lived the experience recounted in 2 Cor 12,1-10. While he was telling the unknown status of his body during the rising, he highlights signs of the altered state of consciousness, an aspect that was not considered in the traditional analysis of the text. These problems are analyzed in this thesis take as instruments of the Religion History and the Neurotheology analysis. Models were built trying to demonstrate a correlation between brain activity and mystical experience. In this respect, we have to point out that the emergence of neurotheology, or spiritual neurology brings a progress to the area of religious experience. Some points of difficult interpretation in pauline text have been clarified under this perspective. The proposal of this study was to build a contextual frame to analyse the ecstatic experience of Paul. The study made it possible to infer that the interdisciplinary approach allows a more appropriate scenario to the understanding and interpretation of the text.
O tema viagem celestial , bem familiar ao mundo mediterrâneo antigo fundamenta-se na crença de que o visionário pode cruzar a fronteira entre a humanidade e a divindade, uma característica constante na literatura apocalíptica. O misticismo judaico antigo era visto como uma importante dimensão dessa tradição, razão pela qual os místicos usaram o termo apocalipse para descrever a revelação de suas experiências. A ascensão de Paulo ao céu, recontada em 2 Cor 12,1-10, é o único relato de primeira mão e a melhor evidência para a prática extática de viagem celestial no judaísmo do primeiro século. De grande interesse nos estudos do Novo Testamento o texto tem sido abordado em forma temática que se estende desde o reconhecimento do apóstolo como agradável à divindade o que lhe rendeu tal feito heróico a uma experiência de punição pelos guardiões dos portões celestiais por não ter sido encontrado nele mérito para aproximar-se do lugar da presença de Deus. Por muito tempo os estudos que predominavam na academia eram os de aspectos teológicos da passagem, tais como o espinho na carne , a missão apostólica , os oponentes de Paulo , entre outros. A linguagem da passagem revela pontos importantes não considerados de forma conjunta para uma interpretação coerente do texto. O uso por parte do apóstolo de expressões do círculo místico-apocalíptico judaico, tais como foi arrebatado , Terceiro Céu , ouviu palavras inefáveis e um espinho na carne precisa ser investigado para a compreensão do que Paulo tinha em mente ao utilizar tais terminologias. Outro problema é a omissão do enfoque experimental descrito na passagem. O apóstolo revela que vivenciou tal experiência recontada em 2 Cor 12,1-10. Ao relatar o desconhecimento do status do seu corpo durante a ascensão ele evidencia sinais do estado alterado de consciência, aspecto não considerado nas análises tradicionais do texto. Esses problemas que são abordados nesta tese tomam como instrumentos da análise a História da Religião e o da Neuroteologia. Modelos foram construídos tentando demonstrar uma correlação entre a atividade cerebral e a experiência mística. Há que se destacar, nesse sentido, que o surgimento da neuroteologia ou neurologia espiritual constitui-se em um avanço na área da experiência religiosa. Pontos de difícil interpretação no texto paulino foram elucidados dentro dessa perspectiva. A proposta deste trabalho, portanto, foi construir um quadro contextual em que a experiência extática de Paulo pudesse ser analisada. O estudo possibilitou inferir que a abordagem interdisciplinar permite alcançar um cenário mais apropriado para a compreensão e interpretação do referido texto.

Abstract:
L’objectif de cette Thèse est une étude de la stabilité des phases d’onde de densité de charge (CDW) et supraconductrice en compétition dans les dichalcogénures lamellaires de métaux de transition. Dans ce but, nous avons employé une technique de synthèse sous haute pression pour induire des modifications de la structure cristalline dans deux composés 1T-TaS2 et 1T-VS2 ayant la même structure 1T (ou de type CdI2) et la même configuration électronique d1. Dans le cas de 1T-TaS2, notre étude de diffraction de rayons X synchrotron et de neutrons sur poudre montre que des conditions de synthèse de 2-6 GPa et 400 °C induisent un désordre dans les plans S et une contraction (expansion) notable de l’axe a dans les plans (c hors plan). Ceci suggère un modèle de désordre d’orientation de ces plans correspondant à l’empilement aléatoire de couches TaS2 de type 1T ou 2H qui correspondent à une coordinance octaédrique ou trigonal prismatique des ions Ta. Ce modèle est en accord avec nos mesures magnétiques et de transport. Cette phase désordonnée est caractérisée par deux phases CDW, une non commensurée, l’autre quasi-commensurée (NCCDW, ICCDW), observées à température ambiante et à basse température respectivement. Ces phases diffèrent de celles observées dans les composés 1T ou 2H synthétisés sous conditions standard. Cette différence met en évidence la métastabilité du composé synthétisé sous haute pression et explique son comportement paramagnétique et métallique/supraconducteur avec Tc ~ 2. 5 K. Afin d’étudier les propriétés supraconductrices, nous avons intercalé le carbone entre les plans à des concentrations x = 0. 05-0. 3 sous les mêmes conditions de pression et de température. Une augmentation notable de Tc a été observée. Notamment, la dépendance de Tc avec x montre un maximum de 4 K pour x=0. 2. Considérant que l’électronégativité du carbone est identique à celle du souffre, ce résultat démontre que la stabilisation de la phase supraconductrice est uniquement due à la séparation des plans et l’effet du dopage sujet à controverse dans la littérature peut être exclu. Dans le cas de 1T-VS2, nous avons réussi la synthèse de la phase stoichiométrique de haute pureté sous forme de poudre à des conditions de haute pression (P = 4 GPa) et à T = 700 °C. Des travaux précédents concernent uniquement la synthèse par dé-intercalation de Li à partir de LiVS2, donc ce résultat montre que 1T-VS2 est une phase métastable à haute pression. Dans ce cas la synthèse à haute pression produit un composé bien cristallisé et sans désordre, ce qui a permis un affinement structural de haute qualité entre 5 et 300 K par diffraction de rayons X synchrotron. Les données montrent que la structure reste de type CdI2 dans toute cette gamme de température. Cependant, une expansion thermique négative de l’axe c est observée dans la gamme 50-150 K, ce qui reflète une augmentation anormale de la distance V-S. Cette anomalie est accompagnée d’un crossover marqué du comportement Curie-Weiss; à haute température la constante de Weiss  = – 43 K révèle un échange antiférromagnétique qui devient négligeable à basse température, alors que le moment localisé et le terme paramagnétique de Pauli restent inchangés. Cela reflète un changement dans les propriétés de cohésion de l’orbitale hybride 3d(V)-3p(S). Le crossover de régime magnétique est corrélé à un crossover de régime de transport; la résistivité électrique dc montre un comportement métallique à haute température et faiblement isolante au dessous de 200 K. Ce résultat contredit la prédiction d’une phase métallique très stable selon des calculs ab initio dans le cadre de la théorie de la fonctionelle densité. Ce désaccord conduit à formuler l’hypothèse que l’interaction d’échange joue un rôle déterminant sur l’état fondamental et que un état métallique peut être stabilisé sous haute pression

Abstract:
Blast furnace operation with coal injection at rates greater than 200 kg coal/tonne of hot metal, a rate less than the theoretical limit, has been often found problematic. The present study aims to gain a better understanding of the fate of injectant coal in the blast furnace by means of characterizing samples extracted from working BFs and pilot-scale rigs. The NMP (1-methyl-2-pyrrolidinone) solvent has been used to extract carbons relevant to BF operation, and comparison of the Size Exclusion Chromatographic patterns of the extracts has indicated that injectant coal is not able to completely combust or even completely pyrolyze during its journey from the tuyere nose through to and out of the “raceway”, and that the secondary reactions e.g. dehydrogenation and repolymerization, of coal tars are closely associated with the formation of the “soot-like” material. This has been confirmed by combined results from analyses using Ultraviolet-fluorescence, FT-IR spectroscopy and Transmission Electron Microscope. In addition, an attempt has been made to use FT-Raman spectroscopy as a relatively rapid technique to characterize various NMP-extracted carbon samples, with the aim to differentiate between carbons from different regions of the blast furnace. Two Raman spectral ratios, i.e.ID/IG ( intensity ratio of D to G band) and IV/IG(intensity ratio of the valley between D and G band to G band), have been found to be suitable parameters to indicate the size of the graphitic crystallites and the overall homogeneity of the carbon structures, respectively. Raman spectroscopy has been found to be able to closely estimate the composition of synthetic carbon mixtures, to indicate the different time-temperature histories that carbons had experienced at tuyere level. Finally, the ID/IG vs. IV/IG mapping has demonstrated its great potential as a reliable method based on Raman spectroscopy to differentiate between various types of carbons.

Abstract:
INTRODUÇÃO: Estudos experimentais e clínicos, realizados por diversos autores, demonstraram a susceptibilidade à compressão nervosa periférica na vigência da diabetes mellitus e modificações na evolução natural da doença após descompressões nervosas cirúrgicas dos sítios propícios a constrição neural. Em membros inferiores, a síndrome do túnel do tarso sobreposta às neuropatias vigentes ainda gera conflitos na literatura. A anatomia do nervo tibial e seus ramos ao nível do terço distal da perna e túnel do tarso apresentam variações importantes que não são contempladas nos livros texto e atlas de anatomia. OBJETIVO: Determinar, através de dissecção em cadáveres frescos, a anatomia topográfica do nervo tibial e seus ramos ao nível do tornozelo, em relação ao túnel do tarso. MATERIAL E MÉTODOS: O estudo foi realizado através da dissecção anatômica bilateral de 26 cadáveres frescos. Foi fixada, entre o cento do maléolo medial e o centro do calcâneo, uma linha de referência (eixo maleolar-calcaneal). Com base nesse eixo as localizações da bifurcação do nervo tibial e dos ramos calcâneos mediais e inferiores foram aferidas em milímetros. Para as bifurcações foi estabelecida uma classificação por tipos de I a V, baseada no posicionamento em relação ao túnel do tarso (definido como dois centímetros proximais e distais ao eixo). Para os ramos calcâneos, a quantidade e seus respectivos nervos de origens também foram analisados. Os resultados foram transformados em taxas (porcentagem) e comparados aos achados de outros estudos. RESULTADOS: Vinte e seis cadáveres (50 pernas) foram pesquisados. A bifurcação do nervo tibial ocorreu sob o túnel em 88% dos casos e proximalmente em 12%. Tivemos o tipo I em 52%, tipo II em 14%, tipo III em 22%, tipo IV em 12% e o tipo V não foi visualizado. Quanto ao ramo calcâneo medial encontramos: um (58%), dois (34%) e três (8%), com a origem mais comum ocorrendo do nervo tibial (90%). De um total de 75 ramos calcâneos mediais dissecados, 40 tiveram sua origem fora do túnel proximalmente (53,3%) e os demais dentro. Com referência ao ramo calcâneo inferior, constatou-se a presença de um único ramo por perna, com 92% emergindo sob o retináculo flexor, 4% proximalmente e 4% distalmente a ele. A origem mais comum foi do nervo plantar lateral (70%), seguida do nervo tibial (18%). CONCLUSÕES: 1- A bifurcação do nervo tibial nos ramos plantares medial e lateral ocorreu sob o retináculo flexor em 88% das pernas, localizando-se, em 70% das vezes, em uma área compreendida entre 10 mm proximais e distais ao EMC. 2- O ramo calcâneo medial apresentou grande variação tanto na sua origem e número de ramos quanto na sua localização em relação ao túnel do tarso. A apresentação de um ramo com origem do nervo tibial, no túnel ou proximalmente a ele, foi a mais observada (58%). 3- O ramo calcâneo inferior esteve sempre presente e com certo grau de variação quanto a sua origem. A apresentação de ramo único oriundo do nervo plantar lateral foi a mais constante (70%)
INTRODUCTION: Experimental and clinical studies developed by several authors displayed the susceptibility to peripheral nerve compression in the presence of diabetes mellitus and changes in the natural evolution of the disease after surgical nerve decompressions of the propitious sites of neural constriction. In lower members, the tarsal tunnel syndrome overlapped on neuropathies still generates conflicts in the available literature. The tibial nerve and its branches anatomy at the distal leg level present significant variations that are not contemplated in textbooks and anatomy atlas. OBJECTIVE: Determine through dissection in fresh cadavers, the topographic anatomy of the tibial nerve and its branches at the ankle, in relation to the tarsal tunnel. MATERIAL AND METHODS: The study was accomplished through bilateral anatomical dissection of 26 fresh cadavers. A reference line was fixed between the center of medial malleolus and the center of calcaneus (malleolarcalcaneal axis - MCA). Based on this axis, the locations of the tibial nerve bifurcation and its medial and lower calcaneal branches were measured in millimeters. For the bifurcations, it was established a classification by types I to V, based in positioning related to the tarsal tunnel (defined as two centimeters proximal and distal to the axis). For the calcaneal branches, the amount and their respective nerves of origin were also analyzed. The results were transformed in rates (percentages) and compared with findings of other studies. RESULTS: Twenty six cadavers (50 legs) were investigated. The tibial nerve bifurcation occurred under the tunnel in 88% of the cases and proximally in 12%. The study had the type I in 52%, type II in 14%, type III in 22%, type IV in 12% and type V was not visualized. As for the medial calcaneal branch it was found: one (58%), two (34%) and three (8%), with the most common source occurring in the tibial nerve (90%). A total of 75 medial calcaneal branches dissected, 40 had their origin outside the tunnel proximally (53.3%) and others had within. With reference to the lower calcaneal branch, it was detected the presence of a single branch per leg, with 92% emerging under the flexor retinaculum, 4% proximally and 4% distally to it. The most common origin was the plantar lateral nerve (70%) followed by the tibial nerve (18%). CONCLUSIONS: 1- The bifurcation of the tibial nerve in the medial and lateral plantar branches occurred under the flexor retinaculum in 88% of the legs, locating, 70% of the time, in an area between 10 mm proximal and distal to the MCA. 2- The medial calcaneal branch presented wide variation as much in its origin as in its location in relation to the tarsal tunnel. The presentation of one branch originating from the tibial nerve in the tunnel or proximally to it was the most observed (58%). 3- The lower calcaneal branch was always present and with a certain degree of variation related to its origin. The presentation of a single branch from the lateral plantar nerve was the most constant (70%)

Abstract:
Les substances naturelles utilisées pour leur propriété adhésive et hydrophobe sont rarement considérés pour les périodes pré- et protohistoriques en Méditerranée nord-occidentale. Pourtant, ces matériaux sont porteurs d’informations techniques, économiques, sociales et environnementales des sociétés du passé.Des marqueurs de l’exploitation du milieu végétal et animal sous forme de produits bruts (résines, cire d’abeille, graisses, bitume) ou transformés (brai de bouleau, goudron de pin, mélanges de substances) ont été identifiés par les techniques de l’archéologie biomoléculaire.Une approche expérimentale a permis de mieux comprendre des segments des chaînes opératoires de fabrication du brai de bouleau et a contribué à la distinction de différents systèmes de production Néolithique sur la base de critères moléculaires.Afin d’évaluer les stratégies d’acquisition des matières premières végétales nous avons intégré dans une approche spatiale un modèle actualiste de végétation couplé aux données archéobotaniques.Les résultats obtenus montrent l’utilisation prépondérante du brai de bouleau au Néolithique. Selon les aires chrono-culturelles, il semble issu de différents systèmes de production et a parfois été transféré. Le bitume, en revanche, semble uniquement exploité localement. Une diversification des substances (cire d’abeille ou résines de Pinaceae), suggérant des modes d’exploitation différents, est plus perceptible au Chasséen où une intensification de l’usage de ces matériaux semble se dessiner.À l’âge du Fer, le goudron de pin est majoritairement exploité en Méditerranée. Le brai de bouleau est uniquement identifié au sein des sociétés protohistoriques corses
Natural substances and transformed organic products used for their adhesive and hydrophobic properties are rarely considered for the pre- and protohistorical periods in the North Western Mediterranean. These materials can however provide technological, economic, social and environmental information about ancient societies.A biomolecular approach was applied to answer questions related to the different types of natural substances exploited by ancient communities. Plant and animal products were identified as raw materials (resins, beeswax, fats or bitumen), or as processed (birch bar tar, pine tar, and mixtures).Experimental work allowed a better understanding of the chaîne opératoire required for the production of birch bark tar. Results showed that it is possible to distinguish between the different manufacturing processes based on molecular criteria.To investigate procurement strategies of plant raw materials, archaeobotanical data was integrated using a spatial approach.The analysis carried out has shown that Birch bark tar was found to be the major product utilised during the Neolithic, its method of production varying depending on the chrono-cultural area. This resource was also sometime transferred. Bitumen, on the other hand, was exploited only when locally available. A diversification of materials (beeswax and Pinaceae resins), suggesting different methods of procurement and processing, was mostly apparent for the Chassey culture, where there appears to be intensification in the use.During the Iron Age, pine tar is the major product in the Mediterranean area. Birch bark tar was only identified in Corsican protohistorical societies

Este estudo objetiva identificar a motivação para a emergência dos conflitos de natureza política na ekklesia de Corinto, logo após a sua fundação, em 50, por Paulo de Tarso. Destaca que as epístolas 1 e 2 Coríntios, redigidas por Paulo e endereçadas a essa comunidade entre 54-60, apresentam conflitos relacionados ao tipo de conduta adotado pelos membros e, sobretudo, a disputas por autoridade dentro da ekklesia, as quais se desdobram numa oposição à autoridade de Paulo como apóstolo . Na averiguação dos conflitos, faz uso de uma metodologia que se apoia na Análise de Conteúdo e nos pressupostos teóricos de Bourdieu acerca da eficácia do discurso e do poder simbólico, e assim investiga o grau de institucionalização do paleocristianismo e os modelos de autoridade apostólica vigentes no século I. Aponta como resultados que a autoridade de Paulo foi contestada porque os grupos paleocristãos não tinham uma referência única de autoridade e que o grau de institucionalização do paleocristianismo na metade do século I se mostrava incipiente, caracterizado pela ausência de fronteiras bem definidas entre os grupos religiosos de tendência judaico-cristã
This study aims to identify the motivation for the emergence of political conflicts in the ekklesia of Corinth, soon after its foundation in 50 A.C., by Paul of Tarsus. It highlights that the letters 1 and 2 Corinthians, written by Paul and addressed to this community between 54-60 A.C., present conflicts related to the type of conduct adopted by its members and, above all, the disputes over authority within the ekklesia, which unfold in opposition to the authority of Paul as "apostle." In the investigation of conflicts, it makes use of a methodology that relies on Content analysis and Bourdieus theoretical assumptions about the effectiveness of speech and symbolic power and thus it investigates the degree of institutionalization of Paleochristianity and models of apostolic authority in force in the 1st century. It points as results that Pauls authority was challenged because Paleochristians groups have not had only one reference of authority and that the degree of institutionalization of Paleochristianity showed itself incipient in the first half of the 1st century, characterized by the absence of well-defined boundaries among groups Jewish Christian tendency

Abstract:
Aminoacyl-tRNA synthetases (ARS) are a family of enzymes that catalyze the charging of amino acids to their cognate tRNA in an aminoacylation reaction. Many members of this family have been found to have secondary functions independent of their primary aminoacylation function. Threonyl-tRNA synthetase (TARS), the ARS responsible for charging tRNA with threonine, is secreted from endothelial cells in response to both vascular endothelial growth factor (VEGF) and tumor necrosis factor-α (TNF-α), and stimulates angiogenesis and cell migration. Here we show a novel experimental approach for studying TARS secretion, and for observing the role of intracellular TARS in the endoplasmic reticulum (ER) stress response and in angiogenesis. Using Western blotting, immunofluorescence microscopy and RT-qPCR we were able to investigate changes in TARS protein and transcript levels. We initially hypothesized that TARS was secreted by exosomal release, and so we treated a human ovarian cancer cell line (CaOV-3) with monensin, an ionophore that increases exosome production, and VEGF to observe changes in intracellular and extracellular TARS protein. Monensin treatment consistently increased extracellular and intracellular TARS protein, however CD63, an exosome marker protein, levels were unaffected by monensin treatment. VEGF had no effect on intracellular TARS. We therefore hypothesized that the TARS response was a result of ER stress. The unfolded protein response (UPR) is a series of signaling pathways that are activated upon ER stress. When CaOV-3 cells were treated with increasing concentrations of monensin, intracellular levels of TARS and p-eIF2α, a downstream UPR target, increased accordingly. Monensin increased intracellular TARS protein and transcript levels in CaOV-3 cells. Monensin also increased DNAJB9, an ER chaperone protein, transcript levels, further confirming ER stress. Interestingly, monensin increased VEGF transcript levels about 6-fold. Borrelidin, a natural TARS inhibitor, also increased VEGF transcript levels, and caused an increase in p-eIF2α protein. Although the mechanism of TARS secretion remains unresolved, these data indicate that intracellular TARS expression increases in response to ER stress by monensin. Given TARS and VEGF transcript expression increased accordingly, it is possible that intracellular TARS may have pro-angiogenic function. Future directions may include investigating TARS interactions with translational control machinery.
