Previous issue date: 2013-06-27The Camorim Oilfield, discovered in 1970 in the shallow water domain of the Sergipe Sub-basin, produces hydrocarbons from the Carm?polis Member of the Muribeca Formation, the main reservoir interval, interpreted as siliciclastics deposited in an alluvial-fluvial-deltaic context during a late rifting phase of Neoaptian age, in the Sergipe-Alagoas Basin. The structural setting of the field defines different production blocks, being associated to the evolution of the Atalaia High during the rift stage and subsequent reactivations, encompassing NE-SW trending major normal faults and NWEW trending secondary faults. The complexity of this field is related to the strong facies variation due to the interaction between continental and coastal depositional environments, coupled with strata juxtaposition along fault blocks. This study aims to geologically characterize its reservoirs, to provide new insights to well drilling locations in order to increase the recovery factor of the field. Facies analysis based on drill cores and geophysical logs and the 3D interpretation of a seismic volume, provide a high resolution stratigraphic analysis approach to be applied in this geodynamic transitional context between the rift and drift evolutionary stages of the basin. The objective was to define spatial and time relations between production zones and the preferential directions of fluid flow, using isochore maps that represent the external geometry of the deposits and facies distribution maps to characterize the internal heterogeneities of these intervals, identified in a 4th order stratigraphic zoning. This work methodology, integrated in a 3D geological modelling process, will help to optimize well drilling and hydrocarbons production. This methodology may be applied in other reservoirs in tectonic and depositional contexts similar to the one observed at Camorim, for example, the oil fields in the Aracaju High, Sergipe Sub-basin, which together represent the largest volume of oil in place in onshore Brazilian basins

Deste modo, a partir da an?lise faciol?gica realizada em testemunhos e perfis geof?sicos, em conjunto com a interpreta??o do volume s?smico 3D, prop?e-se uma metodologia que se baseia na an?lise estratigr?fica de alta resolu??o, aplicada em um contexto geodin?mico transicional entre os est?gios rifte e drifte de evolu??o da bacia, capaz de determinar as rela??es espaciais e temporais das zonas produtoras e as dire??es preferenciais do fluxo de fluidos, empregando para este fim, mapas de is?coras que representam a geometria externa, e mapas de distribui??o de f?cies para as heterogeneidades internas destes intervalos identificados em um zoneamento estratigr?fico de 4? ordem. Esta metodologia de trabalho, integrada em um processo de modelagem geol?gica 3D, vai ser utilizada para estabelecer a geometria da malha de po?os injetores/produtores do intervalo de interesse e pode ser aplicada em outros reservat?rios cujo contexto tect?nico-deposicional seja semelhante ao observado em Camorim, caso dos campos localizados no Alto de Aracaju, Sub-bacia de Sergipe, que juntos comp?em o maior volume de ?leo in place na por??o terrestre das bacias brasileiras

Full textAbstract:
Facial Ageing (FA) is a very fundamental issue, as ageing in general, is part of our daily life process. FA is used in security, finding missing children and other applications. It is also a form of Facial Recognition (FR) that helps identifying suspects. FA affects several parts of the human face under the influence of different biological and environmental factors. One of the major facial feature changes that occur as a result of ageing is the appearance and development of wrinkles. Facial wrinkles are skin folds; their shapes and numbers differ from one person to another, therefore, an advantage can be taken over these characteristics if a system is implemented to extract the facial wrinkles in a form of maps. This thesis is presenting a new technique for three-dimensional facial wrinkle pattern information that can also be utilised for biometric applications, which will back up the system for further increase of security. The procedural approaches adopted for investigating this new technique are the extraction of two-dimensional wrinkle maps of frontal human faces for digital images and the design of three-dimensional wrinkle pattern formation system that utilises the generated wrinkle maps. The first approach is carried out using image processing tools so that for any given individual, two wrinkle maps are produced; the first map is in a binary form that shows the positions of the wrinkles on the face while the other map is a coloured version that indicates the different intensities of the wrinkles. The second approach of the 3D system development involves the alignment of the binary wrinkle maps on the corresponding 3D face models, followed by the projection of 3D curves in order to acquire 3D representations of the wrinkles. With the aid of the coloured wrinkle maps as well as some ageing parameters, simulations and predictions for the 3D wrinkles are performed.

Full textAbstract:
Research on video-based face recognition has started getting increased attention in the past few years. Algorithms developed for video have an advantage from the availability of plentitude of frames in videos to extract information from. Despite this fact, most research in this direction has limited the scope of the problem to the application of still image-based approaches to some selected frames on which 2D algorithms are expected to perform well. It can be realized that such an approach only uses the spatial information contained in video and does not incorporate the temporal structure.Only recently has the intelligence community begun to approach the problem in this direction. Video-based face recognition algorithms in the last couple of years attempt to simultaneously use the spatial and temporal information for the recognition of moving faces. A new face recognition method that falls into the category of algorithms that adopt spatio-temporal representation and utilizes dynamic information extracted from video is presented. The method was designed based on the hypothesis that the strain pattern exhibited during facial expression provides a unique "fingerprint" for recognition. First, a dense motion field is obtained with an optical flow algorithm. A strain pattern is then derived from the motion field. In experiments with 30 subjects, results indicate that strain pattern is an useful biometric, especially when dealing with extreme conditions such as shadow light and face camouflage, for which conventional face recognition methods are expected to fail. The ability to characterize the face using the elastic properties of facial skin opens up newer avenues to the face recognition community in the context of modeling a face using features beyond visible cues.

Full textAbstract:
Context. Real time rendering has many challenges to overcome, one of them being character realism. One way to move towards realism is to use wrinkle maps. Although already used in several games, there might be room for improvement, common practice suggests using two wrinkle maps, however, if this number can be reduced both texture usage and workload might be reduced as well. Objectives. To determine whether or not it is possible to reduce the number of wrinkle maps from two to one without having any significant impact on the perceived realism of a character. Methods. After a base character model was created, a setup in Maya were made so that dynamic wrinkles could be displayed on the character using both one and two wrinkle maps. The face were animated and rendered, displaying emotions using both techniques. A two-alternative forced choice experiment was then conducted where the participants selected which implementation displaying the same facial expression and having the same lighting condition they perceived as most realistic. Results. Results showed that some facial expressions had more of an impact of the perceived realism than others, favoring two wrinkle maps in every case where there was a significant difference. The expressions with the most impact were the ones that required different kinds of wrinkles at the same area of the face, such as the forehead, where one variant of wrinkles run at a more vertical manner and the other variant runs horizontally along the forehead. Conclusions. Using one wrinkle map can not fully replicate the effect of using two when it comes to realism. The difference on the implementations are dependant on the expression being displayed.

Full textAbstract:
Face recognition, although being a popular area of research for over a decade has still many open research challenges. Some of these challenges include the recognition of poorly illuminated faces, recognition under pose variations and also the challenge of capturing sufficient training data to enable recognition under pose/viewpoint changes. With the appearance of cheap and effective multimodal image capture hardware, such as the Microsoft Kinect device, new possibilities of research have been uncovered. One opportunity is to explore the potential use of the depth maps generated by the Kinect as an additional data source to recognize human faces under low levels of scene illumination, and to generate new images through creating a 3D model using the depth maps and visible-spectrum/RGB images that can then be used to enhance face recognition accuracy by improving the training phase of a classification task. With the goal of enhancing face recognition, this research first investigated how depth maps, since not affected by illumination, can improve face recognition, if algorithms traditionally used in face recognition were used. To this effect a number of popular benchmark face recognition algorithms are tested. It is proved that algorithms based on LBP and Eigenfaces are able to provide high level of accuracy in face recognition due to the significantly high resolution of the depth map images generated by the latest version of the Kinect device. To complement this work a novel algorithm named the Dense Feature Detector is presented and is proven to be effective in face recognition using depth map images, in particular under wellilluminated conditions. Another technique that was presented for the goal of enhancing face recognition is to be able to reconstruct face images in different angles, through the use of the data of one frontal RGB image and the corresponding depth map captured by the Kinect, using faster and effective 3D object reconstruction technique. Using the Overfeat network based on Convolutional Neural Networks for feature extraction and a SVM for classification it is shown that a technically unlimited number of multiple views can be created from the proposed 3D model that consists features of the face if captured real at similar angles. Thus these images can be used as real training images, thus removing the need to capture many examples of a facial image from different viewpoints for the training of the image classifier. Thus the proposed 3D model will save significant amount of time and effort in capturing sufficient training data that is essential in recognition of the human face under variations of pose/viewpoint. The thesis argues that the same approach can also be used as a novel approach to face recognition, which promises significantly high levels of face recognition accuracy base on depth images. Finally following the recent trends in replacing traditional face recognition algorithms with the effective use of deep learning networks, the thesis investigates the use of four popular networks, VGG-16, VGG-19, VGG-S and GoogLeNet in depth maps based face recognition and proposes the effective use of Transfer Learning to enhance the performance of such Deep Learning networks.

Coordenação de Aperfeiçoamento de Pessoal de Nível SuperiorThe identification of a person by their face is one of the most effective non-intrusive methods in biometrics, however, is also one of the greatest challenges for researchers in the area, consisting of research in psychophysics, neuroscience, engineering, pattern recognition, analysis and image processing, computer vision and applied in face recognition by humans and by machines. The algorithm proposed in this dissertation for face recognition was developed in three stages. In the first stage feature matrices are derived of faces using the Two-Dimensional Discrete Cosine Transform (2D-DCT) and Two-Dimensional Principal Component Analysis (2D-PCA). The training of the Concurrent Self-Organizing Map (Csoma) is performed in the second stage using the characteristic matrices of the faces. And finally, the third stage we obtain the feature matrix of the image consulting classifying it using the CSOM network of the second step. To check the performance of face recognition algorithm proposed in this paper were tested using three well-known image databases in the area of image processing: ORL, YaleA and Face94.

Previous issue date: 2014-01-13This work proposes the new classifier for face recognition, novelty classifier, which is based on novelty filter proposed by Kohonen. In order to evaluate the new classifier performance, it is performed a comparison with nearest neighboard classifier, which uses the Euclidian distance as distance metric. ORL face database was chosen to be used in this comparison. There was not any pre-processing (photometric or geometric) on face images. It was used the following feature extraction methods: PCA, 2DPCA and (2D)2PCA. Some results in identification mode are exposed through rank 1 recognition rate and CMC curves. In verification mode, the results were presented by Correct Acceptance Rate (CAR), Equivalent Error Rate (EER), ROC curves and Area under the ROC curve (AUC). Results shown that the proposed classifier performs better than others previously published, when the 10-fold Cross Validation method is employed as a test strategy. Recognition rate of 100% is achieved with this test methodology.
Este trabalho propõe a utilização do classificador de novidades para reconhecimento de faces, o qual é baseado no filtro de novidades, proposto por Kohonen. Para avaliar o desempenho do novo classificador é feita uma comparação com o classificador do vizinho mais próximo, usando a métrica da distância euclidiana. A base de dados utilizada para essa comparação foi a base ORL. A informação da face é extraída utilizando os métodos PCA, 2DPCA e (2D)2PCA, sem usar qualquer tipo de pré-processamento (fotométrico ou geométrico). Os seguintes resultados são apresentados no modo de identificação: taxa de reconhecimento rank 1 e as curvas CMC, no modo verificação: as taxas de correta aceitação (CAR), de erro equivalente (EER), as curvas ROC e área sob a curva ROC (AUC). Os resultados obtidos mostraram que o classificador proposto tem um desempenho melhor do que o desempenho do vizinho mais próximo e do que outros classificadores anteriormente publicados usando a mesma base, quando a estratégia de validação cruzada 10-fold é usada, com essa estratégia a taxa de reconhecimento obtida foi de 100%

L'étude de près de 30 000 fragments céramiques, issus de diverses fouilles archéologiques réalisées au Mans (Vindinum), chef-lieu des Cénomans, depuis ces trente dernières années, a permis, en un premier temps, de réaliser un catalogue chrono-typologique regroupant près de 350 formes céramiques, distribuées entre les trois premiers siècles de notre ère. Le matériel céramique a ensuite été mis à contribution pour questionner les pratiques sociales des populations locales, ainsi que pour identifier les réseaux de productions et d'échanges. Enfin, les ressemblances et différences de formes constatées entre les céramiques locales et les autres productions régionales ont permis d'appréhender les influences culturelles s'exerçant sur cette ville. Au-delà de la traditionnelle, mais complexe, question de la « romanisation» des Gaules, c'est à la question des identités régionales que le mobilier céramique permet d'aboutir.

This work has as its theme "The Damage Map of the Facades of the Santa Izabel Theatre". It results from a qualitative literature review, in books and websites containing scientific articles and relevant legislation, and a field visit to the historic building. It provides an overview of the selected theme including historical monuments, relevant legislation, the outer cladding system, pathological manifestations and a damage map. Moreover, it evaluates the pathologies in the building’s facades, specifying the active degradation processes, that is, the main pathologies in coatings and those associated with the building’s natural environment. The mapping of the existing conditions, including degradation and changeability of the stone material along the years, were performed, making it possible to intervene in the Historic Monument, trying to identify the causes and effects of the damage, and to produce the full report of its pathological manifestations and forms of work to satisfactorily remedy the existing damage in the historic building.
Esta dissertação tem como tema “O Mapa de Danos das Fachadas do Teatro de Santa Izabel”. Resulta de uma pesquisa bibliográfica de natureza qualitativa, em livros e sites da internet contendo artigos científicos e legislação pertinente, e de campo, com visitas ao edifício histórico. Apresenta uma visão geral da temática abordada, monumentos históricos, legislação pertinente, o sistema de revestimento de fachada, as manifestações patológicas e mapa de danos. Avalia-se ainda as patologias das fachadas desse edifício, especificando-se os processos de degradação atuantes, ou seja, as principais manifestações em revestimentos associadas ao ambiente natural da edificação. Procedeu-se ao mapeamento das manifestações patológicas existentes, sua degradação e alterabilidade do material pétreo. Observou-se que o Monumento Histórico vem sofrendo ao passar dos anos deterioração por completo em suas fachadas, e por este motivo foi feito um levantamento das manifestações patológicas existentes para ao mesmo tempo lançar mão da ferramenta Mapa de Danos e assim intervir no Monumento Histórico, procurando identificar as causas, origens e mecanismos desses danos, bem como formas de atuar satisfatoriamente na edificação histórica para sanar os danos nela existentes.

This thesis examines the representation of Muslim women in Canadian media, specifically in CBC's Little Mosque on the Prairie ( LMOTP) which represents women in non-Orientalist, realistic portrayals. This thesis traces Luhmann's (1987) theory on representation of society, Millar's (1793) observations about women in society and Hall's (1997) "Other"; and combines them with Said's (1978) Orienralism, Kristeva's (1991) theories on foreigners and Bhabha's (1994) Third Space to study the representation of Muslim women in LMOTP. A qualitative and quantitative content analysis of the first eight episodes investigates how the image of the Muslim woman has been (re)constructed on CBC. This thesis finds that Muslim women in LMOTP are not oppressed or stereotyped; they participate in Canadian culture and the workplace; and they are not considered outsiders. These characters portray Muslim women in Canada who exist in Third Spaces which allow Canadian and Islamic practices to merge resulting in uniquely Canadian artifacts like LMOTP.

Expressões faciais são o resultado de mudanças na musculatura facial em resposta aos estados emocionais e tem um papel fundamental na interação das pessoas. A partir dos estudos iniciados por Darwin, Paul Ekman desenvolveu um estudo sugerindo a existência de sete expressões faciais básicas: alegria, tristeza, medo, nojo, desdém, surpresa e raiva, além da expressão neutra. Posteriormente, no intuito de mensurar o comportamento facial de forma mais aprofundada, Ekman desenvolveu um sistema para medição de todos os movimentos musculares faciais e suas intensidades, o Facial Action Coding System (FACS). O FACS permitiu um avanço em pesquisas de novos métodos para reconhecimento de expressões faciais aplicados nas mais diversas áreas, como educação, psicologia, interação homem-máquina, monitoração de comportamento, dentre outros. O presente trabalho sugere uma nova abordagem para reconhecimento de expressões faciais combinando mapas de saliência para destacar as partes da face que mais concentram as expressões faciais (conspicuidade) e uma rede neural de convolução. A análises mostraram que o sistema proposto alcançou uma precisão média na identificação das 7 (sete) expressões faciais básicas de 90% (noventa por cento) sobre o Extended Cohn-Kanade Data Set. Quando comparado com os trabalhos do estado-da-arte relacionados, o sistema mostrou uma precisão média superior a todos, além de superar, em termos absolutos, todos os trabalhos em 3 (três) das 7 (sete) expressões, demonstrando um resultado promissor.

Full textAbstract:
The RAS-MAPK syndromes are a group of clinically and genetically related disorders, characterized by cardiac defects, facial dysmorphism, cutaneous abnormalities and neurocognitive impairment. The pathogenesis is dysregulation of the RAS-MAPK pathway, and several genes within the pathway are involved. The present thesis aimed at identifying genetic causes in three of the RAS-MAPK syndromes - Noonan syndrome (NS), cardio-facio-cutaneous syndrome (CFC) and Neurofibromatosis-Noonan syndrome (NFNS) - and at correlating genotype with phenotype. A mutation analysis of six genes associated with the RAS-MAPK syndromes in NS and CFC patients revealed mutations in 10/31 patients. The results suggested more complex genetic overlap and genetic heterogeneity among these syndromes than previously believed. Subsequently, gene dosage imbalances of seven RAS-MAPK-syndrome-related genes were investigated in mutation-negative patients. A multiplex ligation-dependent probe amplification strategy was developed that excluded copy number changes of these genes as a common mechanism in NS. Genetic causes of clinical variability in NS were investigated where an atypical and severe NS patient was described. In addition, multiple café-au-lait (CAL) spots affected the patient and four otherwise healthy family members. Molecular analysis of four candidate genes revealed a previously described de novo PTPN11 mutation and an inherited NF1 variant in the patient. Neither of them explained the CAL spots trait, which consequently represented a distinct entity. The results suggested that the atypical and severe phenotype in the patient could be a consequence of an additive effect. Finally, a family displaying NFNS was investigated clinically and molecularly revealing a novel mutation in the GAP-domain of NF1. Furthermore, the results suggested that other RAS-MAPK-syndrome-related genes are not involved in NFNS. A proposal of prioritizing the GAP-domain of NF1 in NFNS was presented. Conclusively, these studies contribute to further understanding of the RAS-MAPK syndromes and facilitate the diagnostic process and future prognosis prediction.

Full textAbstract:
This work sought to investigate the clinical phenotypes and molecular basis of cardio-facio-cutaneous syndrome (CFC), a germline disorder of the Ras-MAPK pathway, like Noonan syndrome (NS) and neurofibromatosis type I, caused by mutations in genes encoding proteins that act within this signal transduction pathway. CFC is most commonly due to mutation in BRAF, and less commonly MAP2K1, MAP2K2 or KRAS. A proportion of patients currently have no mutation identified. Mutations and clinical features of patients with a molecular diagnosis of CFC were investigated, which demonstrated a wide range of causative mutations, and some unclassified variants. Both known and novel clinical features of CFC were identified. A strong association between severe contractures and the p.(Tyr130Cys) mutation in MAP2K1 was found, which has not previously been reported. In contrast to the large number of patients with a confirmed molecular diagnosis, several with a highly suggestive clinical phenotype have been found to have no mutationin any of the known CFC genes. The molecular basis of these presentations was investigated by conventional Sanger sequencing of candidate genes. Fourteen patients with the p.(Ser2Gly) mutation in SHOC2 were identified, with clinical presentations consistent with CFC, NS or CS. Target enrichment and massively parallel sequencing of selected genes was undertaken in ten patients. Mutations in known genes were identified in four patients (including the positive control). Candidate causative variants in novel genes were suggested in two further patients, one of which was confirmed on Sanger sequencing. Whole exome sequencing of patient-parent trios was also undertaken to identify de novo variants. Three trios were analysed, and in one patient with a clinical diagnosis of CFC, a frameshift mutation in NF1 was identified, which was confirmed by Sanger sequencing to be present and de novo. The molecular effects of CFC-associated mutations in BRAF on Ras-MAPK pathway signalling were studied in cell culture systems, using Western blotting for ERK1/2 phosphorylation, in vitro kinase assays and luciferase assays, to assess activity of downstream targets of the Ras-MAPK pathway. Altered pathway activity was demonstrated for novel variants that had not previously been characterised at the molecular level, which was in keeping with the findings of the effects of previously studied mutations. The cardiac phenotype in animal models of CFC, CS and NS/CFC was explored using expression microarrays to identify potentially important genes and pathways in the pathogenesis of hypertrophic cardiomyopathy (a progressive but potentially treatable disease feature) in these conditions. A signature of increased expression of Myh7, the embryonic form of myosin, was identified in the heart of the mouse model of CFC due to a B-Raf mutation at four weeks postnatal age, but comparative analysis suggested significant differences in either the mechanisms causing cardiac phenotypes, or the timescales over which these may exert their effects, in the three models. In summary, the most significant findings of this work were that SHOC2 mutation is a frequent cause of a severe NCFC presentation, and massively parallel sequencing can be an effective means of molecular investigation of this group of disorders. Novel features of CFC syndrome that were identified include severe contractures in association with p.(Tyr130Cys) mutations in MAP2K1. The analysis of mouse models of the NCFCs was hampered by heterogeneity within the expression microarray results, and low levels of expression of the H-Ras mutant allele in the mouse model of Costellosyndrome.

Full textAbstract:
Researchers consistently find that mainstream media often represent women athletes in stereotypical ways including trivialization, sexualization, infantilization, passivity, and utilization of camera down-angles. However, research on new media's visual representation of women athletes is still in its infancy. This study adds to the growing literature on new media's representation of women athletes and concurs with previous findings suggesting that new media might be an outlet that can counter old media gender stereotypes. This thesis used mixed methods of qualitative content analysis and photovoice in order to better understand how Big East volleyball players are represented in photographs on websites: Instances of stereotypes were few, action shots were numerous, and "extreme game faces" emerged as a new category for the visual representation of women athletes. These results might suggest that new media, specifically collegiate athletics' websites and volleyball fans, might defy traditional media's stereotypical gender representations. This thesis found that Big East women volleyball players were, overall, visually represented positively by NCAA.com, BigEast.org, Big East member schools' collegiate athletics websites, and fans of the University of South Florida's volleyball team during, and shortly after, the 2010 season.

Full textAbstract:
This thesis represents two approaches for three dimensional face recognition. In the first approach, a generic face model is fitted to human face. Local shape descriptors are located on the nodes of generic model mesh. Discriminative local shape descriptors on the nodes are selected and fed as input into the face recognition system. In the second approach, local shape descriptors which are uniformly distributed across the face are
calculated. Among the calculated shape descriptors that are discriminative for recognition process are selected and used for three dimensional face recognition.
Both approaches are tested with widely accepted FRGCv2.0 database and experiment protocol. Reported results are better than the state-of-theart systems. Recognition performances for neutral and non-neutral faces are also reported.

This text presents a critical construction on the category recklessness, in the perspective of the professionals of the attendance of the Regional Center of Attention to maltreatment in the Infancy of the ABCD - Diadema Unit. It has as objective to contribute for new looks on this subject. The theoretical landmark that guided the research process all was the social theory of Marx, specifically, the category totality. What it made possible a ampler vision of the category recklessness. In we appropriate them of the content analysis, to analyze the quarrels developed in the research, through the qualitative technique of the focal group. This technique in made possible them to not only approach the subject involving the daily one of work of the CRAMI, but, the feelings and vision that each professional have on this complex and contradictory subject, this fact contributes of substantive form for the analysis. The study on the recklessness in it showed them that this is a category that deserves a bigger attention, in that if relates to the research and scientific studies. We conclude in this study that stops understanding the recklessness, we must have clearly that they exist determinative so that this situation if it configures as negligent and that it is necessary to place in the guideline of quarrels in the spaces of right of the child and the adolescent an ample vision of the meaning of this category

Full textAbstract:
According to most ways of measuring it the Swedish trade union movement is the strongest in the world. The Swedish Trade Union Confederation is the largest and most influential union confederation by far. Since the 1980s though, Sweden experienced a shift in the power relations between employers and unions in favour of the former. This has coincided with a growing importance for political communication, public relations and the mass media. This development has presented the Swedish trade union movement with a multitude of challenges. One of the major ones is how to influence the representations of trade unions and their viewpoints in the news media. The purpose of this study is to describe and try to explain how the Swedish Trade Union Confederation and its affiliated unions act to confront the “medialisation” of the public debate. A combination of research methods are used in this study in order to investigate both the historical development of trade union news management and the use of news management by trade union personnel in their everyday work. The study of how news management historically became a part in the overall union activity was performed through qualitative analysis of archive material. The study of the everyday uses of news management and the factors constraining this work builds upon interviews with the press officers of the TUC affiliated unions and the TUC itself. The study shows how both the historical development and the everyday use of news management by the Swedish trade union movement need to be understood in a context. This context contains political, economical, ideological and organisational structures that at the same time enables and constrains the adaption of news management. The study points towards five central paradoxes which faces the trade unions when they seek desired media attention and try to avoid unwanted publicity. The first paradox concerns how to fight hard in the interest of the members, while at the same time avoid being described as a sectional interest. The second paradox stems from the desire of the trade unions to be perceived as big and strong and how this might result in the labelling of them as ‘Goliath’ during a conflict. The next paradox concerns how trade unions want to show the importance of the work done by their members during a conflict and the way this might lead to media attention about how the strike affects ‘innocent bystanders’. The fourth paradoxes come from the wish of the trade unions to make their local representatives visible in mass media. This could result in unwanted publicity, due to the difference between blue-collar trade unionists and middleclass journalists. The fifth paradox stems from the importance of acting quickly to achieve wanted media attention and to avoid unwanted. The paradox is that it might be hard to be fast and at the same time have a thorough democratic process on a controversial issue.

Full textAbstract:
The thesis argues that to find the places in media culture where the face transmits death, we need to look beyond the immobilised faces of the dead. Drawing on Walter Benjamin's philosophy of the image, the thesis sees the phenomenon of becoming unrecognisable as a particular practice of the image in which the face becomes a viable site for making death transmissible. It is argued that by paying attention to instances in media culture in which a face becomes unrecognisable, we can see how death is made visible as a dialectic between recognition and unrecognisability, appearance and disappearance. By examining the complexity of this particular form of dialectical image in a wide range of media - photography, television and film - the thesis shifts discussion away from questions of representation and faciality that feature so strongly in recent theorisations of the face. Focussing on questions of recognition and recognisability, the thesis proposes a way of thinking about the face that leads to a new conception of death in the media ageDoctor of Philosophy (PhD)

Full textAbstract:
Les estuaires assurent une production élevée et le transfert d'une grande quantité de matière organique (MO) du continent vers l'océan. Une étape importante pour comprendre les échanges de MO à l'interface continent - océan, le long de la côte française de la Manche Orientale, est d'établir un bilan de MO dans les trois plus grands estuaires : la Canche, l'Authie et de la Somme. Dans ce but, il a été réalisé une description sédimentologique et biologique du sédiment de surface et une caractérisation élémentaire et isotopique distinguant l'origine de la MO sédimentaire. La caractérisation du sédiment de surface a été réalisée, de l'étage proche subtidal à supratidal, le long de transects transversaux au fleuve, constituant un réseau de 36, 37 et 39 stations respectivement pour l'estuaire de la Canche, de l'Authie et de la Somme. A partir de cette approche cartographique, un transect représentatif dans l'estuaire de la Canche et de l'Authie a été sélectionné, dans le but de quantifier la minéralisation benthique de la MO sédimentaire, le long du gradient tidal et finalement d'établir un bilan de la dégradation de la MO à l'échelle de l'estuaire. A partir de la caractérisation sédimentologique et biologique du sédiment de surface, le paysage estuarien a été défini selon quatre faciès biosédimentaires : les bancs et plateformes sableuses, les vasières, le bas et le haut des prés salés. Il a été démontré que la répartition de la MO à l'échelle de l'estuaire est contrôlée par la distribution de ces différents faciès biosédimentaires. En effet, les sédiments sableux sont soumis à des contraintes hydrodynamiques importantes dans lequel le dépôt de la MO est limité. En revanche, la MO se dépose préférentiellement dans les lieux où les sédiments fins s'accumulent tels que les vasières et les prés salés. Ces deux environnements sédimentaires sont soumis à des contraintes hydrodynamiques plus faibles, plus particulièrement les prés salés, où la végétation favorise le dépôt et limite la remise en suspension de la MO sédimentaire. En effet, les fortes quantités de MO sédimentaire mesurées dans les prés salés sont issues de la contribution des halophytes en C3 dominant le haut des prés salés. Néanmoins, notre étude montre que la MO déposée le long du gradient tidal est aussi dépendant de l'apport de MO particulaire provenant des communautés phytoplanctoniques fluviatiles et marines/estuariennes. De plus, cette étude a mis en évidence des différences géomorphologique avec un état de maturité des prés salés avancée dans l'estuaire de la Canche, une progradation du pré salé en rive dans l'estuaire de l'Authie et une régression du pré salé, en rive nord dans l'estuaire de la Somme, issu d'un comblement avancé. A l'immersion et à l'émersion, les vasières et les prés salés ont une contribution plus importante que les sédiments perméables à la minéralisation benthique. Paradoxalement, le bilan de la minéralisation benthique, relève une contribution non négligeable des sédiments perméables dans l'estuaire de l'Authie, étant donné leur vaste répartition à l'échelle de l'estuaire. Il a été démontré que la variation spatiale de la minéralisation benthique repose sur les caractéristiques sédimentologiques des faciès biosédimentaires mais aussi sur les facteurs biologiques tels que la macrofaune benthique, le microphytobenthos et le système racinaire des halophytes. Cette thèse contribue à une meilleure définition du rôle des estuaires picards dans le cycle de la MO et permet un premier pas vers la quantification d'un bilan de MO dans les trois principaux estuaires de la Manche OrientaleEstuaries ensure a high production and transfer a large amount of organic matter (OM) from continent to ocean. To understand OM exchanges at the continent-ocean interface along the eastern English Channel coast, it is primordial to establish a mass balance OM budget in the three main estuaries : the Canche, the Authie and the Somme estuaries. In this frame, the sedimentary OM distribution and origin were studied by coupling a sedimentological description of surficial sediments and an elemental and isotopic characterization of the sedimentary OM. Such approach was carried out from near from subtidal to supratidal stages, along transects transversal to the main river channel, resulting in a sampling of 36, 37 and 39 stations respectively from the Canche, the Authie and the Somme estuaries. Based on this mapping approach, a representative transect was selected in the Canche and the Authie estuaries in order to quantify the sedimentary OM benthic mineralization along the tidal gradient and finally to establish an OM mineralization budget at the estuarine scale. Based on the sedimentological and biological characterization of sediments, the estuarine landscape was described according to four biosedimentary facies : sand flats, mud flats, low and high marshes. This study evidenced that the distribution of OM at the estuary scale is mainly controlled by the distribution of these biosedimentary facies. Indeed, sand flats are subject to intense hydrodynamic conditions in which sedimentary OM deposition is limited. On the other hand, OM is preferentially deposited in fine-grained sediments such as mud flats and salt marshes. Both of these sedimentary environments are subjected to lower hydrodynamic conditions, especially salt marshes, where vegetation enhances deposition and limits the resuspension of sedimentary OM. Indeed, the high quantities of sedimentary OM measured in salt marshes mainly originate from C3 halophytes dominating high marsh areas. Nevertheless, our study also evidenced that the deposition of sedimentary OM along the tidal gradient depends on the contribution of particulate OM from fluvial and marine/estuarine phytoplankton communities. Moreover, this study has demonstrated that various evolutions of the geomorphological features, with a mature salt marsh present in the Cancheestuary, a seaward prograding salt marsh on the north shore of the Authie estuary, a salt marsh retreat on the north shore of the Somme estuary resulting from an advanced sand infilling. The OM benthic mineralization campaigns demonstrated that during immersion and emersion periods, mud flats and salt marshes are the main contributors to total OM mineralization along the tidal gradient in contrast to sand flats. The spatial variation mainly depended on the sedimentological characteristics of each of biosedimentary facies but also on biological factors such as benthic macrofauna, microphytobenthos and root system of halophytes. The OM mineralization budget at the estuarine scale showed a significant contribution of sand flats in the Authie estuary given their wide distribution. This thesis contributes to a better definition of the role of "Picard" estuaries in the OM cycling and allows a first step towards the quantification of a mass balance OM budget in the three main estuaries of the eastern English Channel coast

Full textAbstract:
ABSTRACT
Organizations are working to establish and maintain relationships with their target publics using a wide variety of communication tools. How they work at developing this organization-public relationship (OPR) is open to the organization, but previous research suggests there are measurement scales that can indicate what factors an organization may be doing right and those they may need to improve on.
This study examines relationship building efforts of the Tampa Bay Rays organization and the representation it has demonstrated through online content. Utilizing a content analysis, sample articles were collected and coded to examine if relationship components could be found through the organization's affiliated website and the target public's local newspaper. The structure and development of this study was created based on the relationship indicators that were established by Hon and Grunig (1999) and Huang (2001).
Based on the analysis of the results, it was discovered that OPR indicators were being used by the Tampa Bay Rays. Examples of commitment, satisfaction, and control mutuality were the most frequent indicators throughout the online content. Trust and face and favor were the two remaining indicators that showed the lowest frequency of representation through the online content.
From the study, the results revealed: (1) that differences in framing exist; (2) a representation of frequent OPR material and topics does occur; (3) there are thematic patterns on the part of the source; and finally, (4) the organization perspective of what may show up from online content may differ from the outside perspective.

Full textAbstract:
Historiquement et socialement, le visage est chez l'humain une modalité de prédilection pour déterminer l'identité et l'état émotionnel d'une personne. Il est naturellement exploité en vision par ordinateur pour les problèmes de reconnaissance de personnes et d'émotions. Les algorithmes d'analyse faciale automatique doivent relever de nombreux défis : ils doivent être robustes aux conditions d'acquisition ainsi qu'aux expressions du visage, à l'identité, au vieillissement ou aux occultations selon le scénario. La modalité 3D a ainsi été récemment investiguée. Elle a l'avantage de permettre aux algorithmes d'être, en principe, robustes aux conditions d'éclairage ainsi qu'à la pose. Cette thèse est consacrée à l'analyse de visages en 3D, et plus précisément la reconnaissance faciale ainsi que la reconnaissance d'expressions faciales en 3D sans texture. Nous avons dans un premier temps axé notre travail sur l'apport que pouvait constituer une approche régions aux problèmes d'analyse faciale en 3D. L'idée générale est que le visage, pour réaliser les expressions faciales, est déformé localement par l'activation de muscles ou de groupes musculaires. Il est alors concevable de décomposer le visage en régions mimiques et statiques, et d'en tirer ainsi profit en analyse faciale. Nous avons proposé une paramétrisation spécifique, basée sur les distances géodésiques, pour rendre la localisation des régions mimiques et statiques le plus robustes possible aux expressions. Nous avons également proposé une approche régions pour la reconnaissance d'expressions du visage, qui permet de compenser les erreurs liées à la localisation automatique de points d'intérêt. Les deux approches proposées dans ce chapitre ont été évaluées sur des bases standards de l'état de l'art. Nous avons également souhaité aborder le problème de l'analyse faciale en 3D sous un autre angle, en adoptant un système de cartes de représentation de la surface 3D. Nous avons ainsi proposé de projeter sur le plan 2D des informations liées à la topologie de la surface 3D, à l'aide d'un descripteur géométrique inspiré d'une mesure de courbure moyenne. Les problèmes de reconnaissance faciale et de reconnaissance d'expressions 3D sont alors ramenés à ceux de l'analyse faciale en 2D. Nous avons par exemple utilisé SIFT pour l'extraction puis l'appariement de points d'intérêt en reconnaissance faciale. En reconnaissance d'expressions, nous avons utilisé une méthode de description des visages basée sur les histogrammes de gradients orientés, puis classé les expressions à l'aide de SVM multi-classes. Dans les deux cas, une méthode de fusion simple permet l'agrégation des résultats obtenus à différentes échelles. Ces deux propositions ont été évaluées sur la base BU-3DFE, montrant de bonnes performances tout en étant complètement automatiques. Enfin, nous nous sommes intéressés à l'impact des dégradations des modèles 3D sur les performances des algorithmes d'analyse faciale. Ces dégradations peuvent avoir plusieurs origines, de la capture physique du visage humain au traitement des données en vue de leur interprétation par l'algorithme. Après une étude des origines et une théorisation des types de dégradations potentielles, nous avons défini une méthodologie permettant de chiffrer leur impact sur des algorithmes d'analyse faciale en 3D. Le principe est d'exploiter une base de données considérée sans défauts, puis de lui appliquer des dégradations canoniques et quantifiables. Les algorithmes d'analyse sont alors testés en comparaison sur les bases dégradées et originales. Nous avons ainsi comparé le comportement de 4 algorithmes de reconnaissance faciale en 3D, ainsi que leur fusion, en présence de dégradations, validant par la diversité des résultats obtenus la pertinence de ce type d'évaluation.

Full textAbstract:
The purpose of this study is to analyze the sedimentology and stratigraphy of the Middle Jurassic Preuss Sandstone and re-evaluate past sedimentological interpretations. The Preuss is located in northern Utah, western Wyoming and eastern Idaho and is stratigraphically equivalent to the Entrada Sandstone, which is Callovian in age (Dossett et al., 2014). This study is the first attempt at 1) a sequence stratigraphic framework, 2) a petroleum system analysis and 3) an extraterrestrial analog study for the Preuss. This study frames the Preuss within three broad facies groups: marine, coastal and terrestrial. The marine group includes the open marine and restricted marine facies with associated subfacies, the coastal group includes coastal sabkha and associated subfacies, and the terrestrial group includes alluvial, inland sabkha and eolian facies with associated subfacies. Three sections in northern Utah and one section in eastern Idaho compromise the focus of this study. The three Utah sections were measured and described, and samples were collected from two Utah sections and the Idaho section. The Preuss Sandstone was deposited in an asymmetrical retroarc basin, consequently the Preuss thickens from the east towards west-central Utah and the Jurassic Elko highlands. The deposits are mostly terrestrial, which is in accord with recent sedimentological interpretations, but at odds with the old paradigm, which postulates that the Entrada and Preuss were largely tidal in origin. There are marine transgressions within the trough of the retroarc basin, and the transgressions affect terrestrial sedimentary patterns. During marine incurstions, alluvium shed off the highlands is confined west of the seaway, and does not prograde east of the trough until all the available accommodation is filled. The Preuss was deposited during a complete third-order sequence-stratigraphic cycle that lies within the Lower Zuni II second-order lowstand. The Preuss Sandstone can be used as an outcrop analog for ancient and modern environments both here on Earth and on other planetary bodies. The petroliferous Norphlet Formation along the U.S. Gulf Coast was deposited in an environment very similar to the Preuss, but the Waltherian succession of facies might be slightly different. Likewise, the facies present in the Preuss are analogous to modern arid environments, such as the Persian Gulf. Furthermore, the alluvial, sabkha, eolian and shallow marine facies of the Preuss are highly similar to facies observed in ancient Martian environments and modern environments on Saturn's moon, Titan.

A violência é reconhecida como um importante problema de saúde pública. A criança e o adolescente são vítimas frequentes de atos abusivos. Em razão do envolvimento frequente de estruturas da região de cabeça/pescoço e da cavidade bucal, as manifestações físicas colocam o cirurgião-dentista, em uma posição privilegiada para a identificação de vítimas de violência. O objetivo desta pesquisa foi avaliar, por meio dos registros de exames de corpo de delito, do Departamento Médico Legal, no município de Pelotas/RS, o perfil das crianças e adolescentes vítimas de casos de violência e avaliar a prevalência e características de lesões de cabeça e pescoço, bem como realizar uma revisão sistemática a respeito do conhecimento, atitudes e experiências dos estudantes de Odontologia em relação aos casos de violência contra crianças e adolescentes. Foram avaliados laudos médicos de crianças e adolescentes (0-19 anos), que realizaram exame de corpo de delito durante o período de janeiro de 2011 a dezembro de 2015, que apresentaram ofensa à integridade e/ou saúde da vítima. Neste estudo, 2.717 crianças e adolescentes foram submetidos a exame de corpo de delito, com um total de 2.172 exames resultantes de violência; lesões que tiveram como etiologia a agressão física (1.952) apresentaram maior prevalência. A análise das vítimas revelou que a maioria era branca (74.77%) e do sexo feminino (50.23%), com idade média de 14,63. A região da cabeça e pescoço foi afetada na maioria dos casos de violência (57.92%). Após o ajuste, a ocorrência de violência foi positivamente associada ao sexo feminino (PR 1.12, IC 95% 1.08-1.17), os grupos etários de 11-15 anos (RP 1.29, IC 95% 1.14-1.47) e 16-19 anos (PR 1.15, IC 95% 1.01-1.30) e lesões na região da cabeça e pescoço (RP 1.23, IC 95% 1.18-1.29). Em relação a revisão sistemática as bases de dados Pubmed, Web of Science, Scopus, LILACS e Scielo foram pesquisadas, não houve restrição de ano e idioma, 16 artigos foram incluídos no estudo. Dos estudos avaliados, todos mostraram que os estudantes de Odontologia têm conhecimento sobre casos de violência contra crianças e adolescentes, apesar das deficiências em relação ao diagnóstico e denúncia. Verificou-se que os alunos que se encontravam em períodos mais avançados apresentaram melhores conhecimentos se comparados aos níveis anteriores. Os achados deste estudo, reafirmam a importância do cirurgião- dentista no diagnóstico e denúncia de suspeitas de abuso infantil, realizando um atendimento integral ao paciente.
Violence is recognized as a major public health problem. Children and adolescents are frequent victims of abusive acts. Due to the frequent involvement of structures in the head / neck region and the oral cavity, the physical manifestations place the dental surgeon in a privileged position to identify victims of violence. The objective of this study was to evaluate the profile of children and adolescents victims of violence and to evaluate the prevalence and characteristics of head and neck injuries, through the records of body of crime examinations of the Legal Medical Department, in the city of Pelotas, as well as to carry out a systematic review regarding the knowledge, attitudes and experiences of dentistry students in relation to cases of violence against children and adolescents. The medical reports of children and adolescents (0-19 years old), who underwent examination of the offender's body during the period January 2011 to December 2015, that presented an offense to the integrity and / or health of the victim were evaluated. In this study, 2.717 children and adolescents were submitted to a body of crime, with a total of 2.172 exams resulting from violence; Lesions that had as etiology the physical aggression (1,952) presented higher prevalence. The analysis of the victims revealed that the majority were white (74.77%) and female (50.23%), with a mean age of 14.63. The head and neck region was affected in most cases of violence (57.92%). After adjustment, the occurrence of violence was positively associated with female gender (PR 1.12, 95% CI 1.08-1.17), age groups of 11-15 years (RP 1.29, CI 95% 1.14-1.47), and 16-19 years (PR 1.15, 95% CI 1.01-1.30) and lesions in the head and neck region (RP 1.23, 95% CI 1.18-1.29). In relation to the systematic review, Pubmed, Web of Science, Scopus, LILACS and Scielo databases were searched, there was no restriction of year and language, 16 articles were included in the study. From the studies evaluated, all showed that dentistry students are aware of cases of violence against children and adolescents, despite deficiencies in relation to diagnosis and denunciation. It was verified that the students who were in more advanced periods presented better knowledge when compared to the previous levels. The findings of this study reaffirm the importance of the dental surgeon in the diagnosis and denunciation of suspected child abuse, performing integral care to the patient.

This paper explores the influences, ideas and motivations behind my MFA thesis exhibition. It primarily focuses on how I developed my work for the show in connection to my previous work as well as work created by other artists who explored the impacts of new media in the last decade. With the advancement of social media, digital technologies no longer have their infamous coldness. Our perceptions and the metaphors in language are all reflected onto the machines we create while in return they also shape and redefine our lives. It becomes increasingly difficult to talk about dialectics such as machine-human, virtual-real, and nature-culture. With the aid of some humor, I attempted to reflect on the marriage of these old oppositions and this paper will discuss the foundations of these ideas as well as my practice in general.

B cells have a central role in the pathogenesis of collagen-induced arthritis (CIA), an animal model of the autoimmune disease rheumatoid arthritis. In this report, a specific subset of an innate type of B cells, B-1 B cells, have been studied for the involvement in CIA. The B-1 B cells were shown to produce small amounts of collagen-specific antibodies upon stimulation in vitro, suggesting that they play a minor role in the development of CIA. This report also includes how marginal zone B cells, another innate type of B cells with natural collagen-reactivity, can be identified in the medullary sinuses of lymph nodes of collagen-immunized mice, implying involvement in auto antigen trapping.

O presente estudo procura explorar a relação entre o índice de massa corporal (IMC), a auto-imagem corporal da criança, a percepção materna da imagem corporal das crianças e as crenças, atitudes e práticas parentais face à alimentação. O estudo incide sobre 333 crianças com três anos e respectivas mães.
Os resultados mostram haver uma percentagem significativa de crianças com excesso de peso (28%). Os dados relativos à auto-imagem corporal da criança revelam a inadequação da avaliação que as crianças fazem da sua imagem corporal ou a inadequação do próprio instrumento para avaliar a imagem corporal das crianças com três anos. Verifica-se ainda que as mães apresentam uma avaliação distorcida da imagem corporal das crianças; ABSTRACT: Childhood obesity is an increasingly important issue, with a high prevalence worldwide. Is a multifactorial disorder with serious consequences for physical and mental health.
This study explores the relationship between body mass index (BMI), children body image, parental perceptions of children body image and parental beliefs, attitudes and practices face food. The study focuses on 333 children three years old and their mothers.
The results show that there is a significant number of children who are overweight (28%). Data on children body image revealed the inadequacy of the assessment that children make of their body image or the inadequacy of the instrument itself to assess the body image of children under three years old. It appears that mothers have a distorted body image assessment of children, yet the maternal perception of children body image and BMI of those children are correlated.

As advances in thin films are made there is a parallel requirement to develop equipment capable of measuring their properties accurately and consistently. In addition there is a need to understand the parameters that are measured. Typical DPI measurements allow both the refractive index (related to density) and the thickness of the adsorbed layer to be calculated with relatively few assumptions, to a very high precision in real time. This thesis presents the research undertaken to develop multiple path length dual polarisation interferometry (MPL-DPI) and absorption enhanced dual polarisation interferometry (AE-DPI). In addition research is presented that can be used to improve the interpretation of the measured parameters for inhomogeneous films and uniaxial films. The new Interferometric technique MPL-DPI allows the thickness and refractive index of in situ and ex-situ coated ultra-thin films to be measured. The procedures and the mathematics required to calculate the properties of films have been described and the technique verified. The technique was demonstrated using films of PMMA, where good agreement was found with complementary techniques. Furthermore, some key features of MPL-DPI were demonstrated using the measurements of interfacially grafted acrylic acid. The absorption enhanced DPI uses the attenuation of the light within the waveguide, due to the light absorbing properties of a film on its surface. As the composition of a film changed, it was shown that the refractive index and extinction coefficients could be used to separate the mass of the components of the film that absorbed light, from the components of the film that did not. With the use of a semi-uniaxial model, the extra data from the attenuation in two polarisations was used to fit the extraordinary and ordinary extinction coefficients. The extraordinary and ordinary extinction coefficients were used to demonstrate that molecular orientation could be implied. The influence that an inhomogeneous film has on the measured thickness, refractive index and extinction coefficient fitted by homogeneous models were investigated. Formulas are presented to explain the thickness, refractive index and extinction coefficient of the measured film. A formula for the total mass per unit area that uses the refractive index was created to account for films that contain molecules of different refractive index increments (dn/dc's). To separate the mass of the individual molecular species from the total mass per unit area, formulas that use the extinction coefficient were derived so molecules that absorb light could be separated from those that do not. The mass calculated from the refractive index and the mass calculated from the extinction coefficient were also examined for uniaxial films. For uniaxial films both measures of the adsorbed mass were found to be relatively accurate and benefited from a partial cancellation of errors. The accuracy of the measurements made by dual polarisation interferometry technology is systematically examined throughout this thesis. Improvements in the calibration routines are suggested and a procedure for the identification and reduction of errors in the phase and contrast is demonstrated.

Der untertägige Abbau von Steinkohle führt zu Bewegungen des überlagernden Gebirges und der Tagesoberfläche. Eine Bewegungsprognose ist im Hinblick auf entstehende Bergschäden weltweit von großer Bedeutung. In dieser Arbeit wird untersucht, ob eine Prognose von Bodenbewegungen im amerikanischen Steinkohlenbergbau mit einem in Europa bewährten Verfahren, einem dynamischen stochastischen Senkungsmodell, möglich ist. Dazu wurde eine Literaturstudie über den bisherigen Kenntnisstand in den USA durchgeführt, abbaubegleitende Bodenbewegungsmessungen aus dem Steinkohlengebiet der Appalachen ausgewertet und durch Modellrechnungen nachgebildet. Es wurde darüber hinaus untersucht, welchen Einfluss die spezifischen Abbaubedingungen und die räumliche und zeitliche Abbauführung auf die Größe und Dynamik von Bodenbewegungen haben. Die theoretischen und praktischen Untersuchungen zeigen einen deutlichen Know-how Vorsprung des europäischen Bergbaus in den Bereichen der Senkungsmodellierung und Bewertung abbauinduzierter Bodenbewegungen und belegen die Anwendbarkeit des Senkungsmodells. Es wurden wichtige Erkenntnisse gewonnen, die Möglichkeiten und Grenzen einer Optimierung des Abbauzuschnitts und der zeitlichen Abbauführung im Sinne einer bergschadensmindernden Abbauplanung aufzeigen. Die Arbeit trägt zur Verbesserung der bergmännischen und markscheiderischen Abbauplanung im Steinkohlenbergbau bei.

L'activació sostinguda de Hog1 porta a una inhibició del creixement cel·lular. En aquest treball, hem observat que el fenotip de letalitat causat per l'activació sostinguda de Hog1 és parcialment inhibida per la mutació del complexe SCFCDC4. La inhibició de la mort causada per l'activació sostinguda de Hog1 depèn de la via d'extensió de la vida. Quan Hog1 s'activa de manera sostinguda, la mutació al complexe SCFCDC4 fa que augmenti l'expressió gènica depenent de Msn2 i Msn4 que condueix a una sobreexpressió del gen PNC1 i a una hiperactivació de la deacetilassa Sir2. La hiperactivació de Sir2 és capaç d'inhibir la mort causada per l'activació sostinguda de Hog1.També hem observat que la mort cel·lular causada per l'activació sostinguda de Hog1 és deguda a una inducció d'apoptosi. L'apoptosi induïda per Hog1 és inhibida per la mutació al complexe SCFCDC4. Per tant, la via d'extensió de la vida és capaç de prevenir l'apoptosi a través d'un mecanisme desconegut.
Sustained Hog1 activation leads to an inhibition of cell growth. In this work, we have observed that the lethal phenotype caused by sustained Hog1 activation is prevented by SCFCDC4 mutants. The prevention of Hog1-induced cell death by SCFCDC4 mutation depends on the lifespan extension pathway. Upon sustained Hog1 activation, SCFCDC4 mutation increases Msn2 and Msn4 dependent gene expression that leads to a PNC1 overexpression and a Sir2 deacetylase hyperactivation. Then, hyperactivation of Sir2 is able to prevent cell death caused by sustained Hog1 activation.
We have also observed that cell death upon sustained Hog1 activation is due to an induction of apoptosis. The apoptosis induced by Hog1 is decreased by SCFCDC4 mutation. Therefore, lifespan extension pathway is able to prevent apoptosis by an unknown mechanism.

Tese de Doutoramento em Ciência e Tecnologia Web em associação com a Universidade de Trás-os-Montes e Alto Douro, apresentada à Universidade AbertaA recolha e análise sequencial de dados multimodais do rosto humano é um problema importante em visão por computador, com aplicações variadas na análise e monitorização médica, entretenimento e segurança. No entanto, devido à natureza do problema, há uma falta de sistemas acessíveis e fáceis de usar, em tempo real, com capacidade de anotações, análise 3d, capacidade de reanalisar e com uma velocidade capaz de detetar padrões faciais em ambientes de trabalho. No âmbito de um esforço contínuo, para desenvolver ferramentas de apoio à monitorização e avaliação de emoções/sinais em ambiente de trabalho, será realizada uma investigação relativa à aplicabilidade de uma abordagem de análise facial para mapear e avaliar os padrões faciais humanos. O objetivo consiste em investigar um conjunto de sistemas e técnicas que possibilitem responder à questão de como usar dados de sensores multimodais para obter um sistema de classificação para identificar padrões faciais. Com isso em mente, foi planeado desenvolver ferramentas para implementar um sistema em tempo real de forma a reconhecer padrões faciais. O desafio é interpretar esses dados de sensores multimodais para classificá-los com algoritmos de aprendizagem profunda e cumprir os seguintes requisitos: capacidade de anotações, análise 3d e capacidade de reanalisar. Além disso, o sistema tem que ser capaze de melhorar continuamente o resultado do modelo de classificação para melhorar e avaliar diferentes padrões do rosto humano. A FACE ANALYSYS, uma ferramenta desenvolvida no contexto desta tese de doutoramento, será complementada por várias aplicações para investigar as relações de vários dados de sensores com estados emocionais/sinais. Este trabalho é útil para desenvolver um sistema de análise adequado para a perceção de grandes quantidades de dados comportamentais.
Collecting and analyzing in real time multimodal sensor data of a human face is an important problem in computer vision, with applications in medical and monitoring analysis, entertainment, and security. However, due to the exigent nature of the problem, there is a lack of affordable and easy to use systems, with real time annotations capability, 3d analysis, replay capability and with a frame speed capable of detecting facial patterns in working behavior environments. In the context of an ongoing effort to develop tools to support the monitoring and evaluation of human affective state in working environments, this research will investigate the applicability of a facial analysis approach to map and evaluate human facial patterns. Our objective consists in investigating a set of systems and techniques that make it possible to answer the question regarding how to use multimodal sensor data to obtain a classification system in order to identify facial patterns. With that in mind, it will be developed tools to implement a real-time system in a way that it will be able to recognize facial patterns from 3d data. The challenge is to interpret this multi-modal sensor data to classify it with deep learning algorithms and fulfill the follow requirements: annotations capability, 3d analysis and replay capability. In addition, the system will be able to enhance continuously the output result of the system with a training process in order to improve and evaluate different patterns of the human face. FACE ANALYSYS is a tool developed in the context of this doctoral thesis, in order to research the relations of various sensor data with human facial affective state. This work is useful to develop an appropriate visualization system for better insight of a large amount of behavioral data.

Full textAbstract:
Dissertação de Mestrado em Geociências apresentada à Faculdade de Ciências e TecnologiaThe sabkha Oum Dba is a wide salt flat located approximately 35 Km north of the city of Laayoune, in Western Sahara (Morocco). Carbonate deposits were examined in detail for their geologic and microbiologic features in the southernmost sector of the sabkha, with the purpose of understanding the interactions between physico-chemical and biological processes that help in the production of non-marine carbonate deposits. Of the different continental environments in which carbonate deposits can precipitate, we focus on deposits accumulated in an ephemeral lake where a hydrological system sustained by ambient-temperature groundwater produced suitable conditions for the formation of microbial-derived carbonates that locally pass to travertine. This sabkha represents a typical example of a modern environment with ongoing calcium carbonate precipitation, where living microbial mats represent the biotic feature responsible for suitably influence the environment and leading to the formation of calcium carbonate precipitates. Microbial communities often form aggregates, biofilm, or mat communities in response to environmental stressful conditions such as hypersalinity. Extracellular polymeric substances (EPS), widely produced by microbes, accumulate outside cells to form a protective and adhesive matrix that attaches the microorganisms to substrates and provides physico-chemical protection and can also aid nutrient absorption. The optical microscope investigation of these carbonates has revealed many morphologies that can be attributable to microbially mediated processes. Petrographic observations suggest that microbial evidence include stromatolitic wavy and planar laminations, filamentous aggregates and isolated filaments, diatoms, EPS, microbial clots and peloids. The correct interpretation of the microbial mats, their interactions and features and the environmental conditions where they are formed are important to understand analogous structures in the past and can be applied in the interpretation of their remains – such morphological fossils and biominerals. This work sought to characterize the microbial mats and carbonate deposits from a biosedimentological perspective, in terms of their morphology, texture and composition, and through a direct field observation of the environment where the same carbonate morphologies are currently forming.
A sabkha Oum Dba é caracterizada como sendo um amplo salar localizado a aproximadamente 35 km a norte da cidade de Laayoune, no Saara Ocidental (Marrocos). Dois exemplos de depósitos carbonatados que afloram nesta área, foram examinados em detalhe devido às suas importantes características geológicas e microbiológicas. O primeiro objectivo é analisar e compreender as interações entre os processos físico-químicos e biológicos envolvidos na produção de depósitos carbonatados continentais. O actual interesse em compreender os processos que promovem a formação destes depósitos tem sido proporcionado, em grande parte, pelas recentes descobertas de importantes reservatórios de hidrocarbonetos nos carbonatos continentais das bacias do Atlântico Sul. De entre os diferentes ambientes continentais nos quais ocorre precipitação de carbonato de cálcio, este estudo tem enfoque nos depósitos acumulados na sabkha Oum Dba, um ambiente hipersalino e hiperárido, constituído por um complexo sistema hidrológico alimentado por uma fonte de água subterrânea, promovendo as condições necessárias para formar carbonatos microbais que passam localmente a travertinos. Esta sabkha representa um exemplo típico de sabkha de ambiente moderno com precipitação contínua de carbonato de cálcio, no qual se desenvolvem vastos tapetes microbianos que representam o componente biótico responsável por influenciar o meio-ambiente e criar as condições propícias para formar minerais de carbonato de cálcio. As comunidades microbianas formam biofilmes e organizam-se em agregados e estratos (tapetes) com produção de mucilagens, como resposta às condições ambientais extremas, como a hipersalinidade. Estas substâncias poliméricas extracelulares (EPS), produzidas por micróbios, acumulam-se fora das células para formar uma matriz que ajuda a na protecção e adesão dos microorganismos a um substrato, captura e aglutinação sedimentos e auxílio na absorção de nutrientes. As análises microscópicas revelam diversos tipos de micromorfologias e microfácies que, em alguns casos, podem ser atribuídas a processos tipicamente mediados por microorganismos. Observações petrográficas mais detalhadas sugerem que as principais evidências microbianas incluem: laminações onduladas e planares, agregados filamentosos e filamentos isolados, diatomáceas e organismos filamentosos incrustados, estrutuas de EPS, coágulos microbianos e peloides. A análise e interpretação correcta das comunidades microbianas, das suas interacções metabólicas e das condições locais do meio-ambiente onde se desenvolvem, são importantes para entender as estruturas análogas do passado e podem também ser aplicadas na interpretação do seu o registro fossil. O segundo objectivo deste trabalho é caracterizar os depósitos carbonatados aflorantes na sabkha Oum Dba, sob uma perspectiva biossedimentológica, em termos da sua morfologia e textura e e composição e através da observação directa das morfologias carbonatadas que se estão a formar actualmente na sabkha.

Full textAbstract:
Introdução: Como qualquer intervenção cirúrgica, também a Cirurgia Estética Plástica provoca lesões a nível celular e vascular, dando origem a algumas reações pós-operatórias, caracterizadas por um quadro inflamatório com aparecimento de edema e dor. o linfedema e a dor podem condicionar bastante a recuperação do paciente, por isso quando detetados, devem ser os primeiros sintomas a ser tratados numa pós-cirurgia. O Fisioterapeuta é um dos grandes pilares no tratamento do linfedema, uma vez utiliza a DLM. Contudo não existe uniformidade relativamente ao encaminhamento dos indivíduos pós-cirurgia para a Fisioterapia.
Problema: O problema de estudo é perceber o que os médicos cirurgiões plásticos mais indicam em caso de edema pós traumático da face, pós cirurgia plástica estética.
Objectivos: O principal objectivo deste estudo é perceber qual é a intervenção e/ou técnica que os médicos cirurgiões plásticos mais indicam em caso de edema pós traumático. De modo a compreender o papel que a Fisioterapia desempenha para esta população como adjuvante á intervenção cirúrgica.
Metodologia: Estudo quantitativo, de desenho não experimental que utiliza uma componente essencialmente descritiva, baseada na entrega e preenchimento de um questionário que será previamente elaborado e validado pelo investigador.
Discussão: Apesar da eficácia da Fisioterapia Dermatofuncional no pré e pós operatório de cirurgia estética plástica, a maioria dos pacientes submetidos às cirurgias plásticas não são encaminhados para a realização de tratamentos pós-operatórios com fisioterapeutas, ou o são em fases tardias, o que pode levar a resultados poucos satisfatórios.
Conclusão: A elaboração deste projecto é uma forma de poder despertar o interesse, dos Fisioterapeutas para a realização de novos estudos de investigação de modo a garantir que a tomada de decisão clínica seja baseada na evidência. Os objetivos do estudo foram alcançados contudo as fases de elaboração do estudo revelam aspectos positivos e algumas limitações. Este contribuiu para a formação pessoal e profissional, contribuindo para a escassa investigação nesta área.

This thesis addresses the topic of mass influx of refugees and its possible solutions. It examines the concept of prima facie refugee status determination in group situations, which is plentifully used in states of the economic South as a solution to mass influx of refugees. Despite its ample use, it is not entirely clear what can be understood by it. A better way to tackle mass influxes of refugees is sought here in response to the European migration "crisis" which has shed light on the unpreparedness of the Common European Asylum System for a large scale influx. The prima facie refugee status determination is put here as an opposite to individualized refugee status determination, which is assumed by the western doctrine and practice to be the only possible way of determining refugee status under the 1951 Convention. Even though individualized refugee status determination may be an appropriate tool in times of relatively low number of refugees, as it has been the case for a long time at the European continent, it may be different in situations of mass influx of refugees. Such individualized refugee status determination is very costly and lengthy procedure and as such not very suitable for situation of mass influx of refugees. To answer the question of whether the prima facie refugee status...

Dissertação de Mestrado Integrado em Engenharia Electrotécnica e de Computadores apresentada à Faculdade de Ciências e TecnologiaLight-field cameras are devices capable of acquiring a plenoptic function (light-field at4D), and are able through a single shot estimate the depth of a scene, this is possible thanksto the fact that a single 3D point is reprojected to several images. Besides the multi-focuscameras, get a higher quality and a higher resolution, in this dissertation was used the Illumcamera produced by Lytro, our choice was made because the rendering cost is smaller, andthe literature gives a bigger importance to this type of camera.First was used a toolbox that allow to decode a picture, get the matrix of intrinsicparameters, and use that to rectify the images.With the rectified light-field, was used a method to estimate the depth map, that isavailable online , so was compared this one with the ones obtained for Kinect v1 and thedepth map obtained by a par of stereo cameras. The depth map was obtained by usingmatlab functions for the Kinect v1 and for the Duo3d-MC the software available for thecompany Duo3D. For this efect the scene that was created, consisted in objects that thereal dimensions of them were known, like a cylinder with 7.5cm of radius and 20 cm of height,also a sphere which the radius is approximately 10 cm. As well, a Styrofoam bust was usedin order to realize a qualitative comparison, that approximates to a real face.At last, the Illum camera was used in order to perform the facial reconstruction, to verifyif the chosen method would produce satisfying results, in different environments and people.
Câmaras de campos de luz são dispositivos capazes de adquirir uma função de luz (campode luz a 4D), e através de uma imagem estimar a profundidade do cenário presente, isto épossível devido ao facto de ser criada redundância através de um ponto 3D ser projetado emdiferentes sub-imagens.Apesar de as câmaras multi-focus, possuírem uma qualidade superior e uma maior resolução, foi utilizada ao longo desta dissertação a câmara Illum produzida pela Lytro, devidoao facto de o custo de renderização de uma imagem ser substancialmente inferior, e tambémde na literatura existir uma maior atenção a estas.Começou-se por utilizar uma toolbox que se encontra presente online, que nos permitedescodificar uma imagem, como também estimar a matriz de parâmetros intrínsecos dacâmara, para posteriormente se poder retificar as imagens obtidas.A partir do campo de luz retificado, utilizou-se um método para a estimação do mapa deprofundidade, que se encontra disponível online. Com o mapa de profundidade, realiza-seuma comparação deste mapa, com os mapas obtidos de uma câmara Kinect V1 e com omapa obtido por um par de câmaras stereo. Para a obtenção dos mapas de profundidade decada uma destas foi utilizado, para o caso da Kinect v1 as funções presentes no matlab, e nocaso do par de câmaras stereo, o software disponibilizado pela empresa fabricante da mesma.Para o efeito utilizou-se um ambiente onde eram conhecidas as dimensões dos objetos, comoum cilindro de raio 7.5 cm e altura 20 cm e de uma esfera com raio aproximadamente de 10cm. Também se realizou uma comparação de modo qualitativo a algumas imagens retiradasa um busto de esferovite.Finalmente utilizou-se a câmara Illum para a reconstrução de imagens de faces reais,de modo a comprovar se o método escolhido produzia resultados satisfatórios em diferentescondições e diferentes pessoas.

Trabalho Final do Curso de Mestrado Integrado em Medicina, Faculdade de Medicina, Universidade de Lisboa, 2014Since the mid-80s that the Ras/MAPK pathway has triggered science’s attention, due to its influence on cell proliferation control, differentiation and cell survival. Hence, changes in its constituents are causing significant changes in the human body. Although somatic mutations were firstly widely investigated and were said to be involved in the development of 30% of the neoplasms described, nowadays great relevance is attributed to germline mutations. The aim of this review is to highlight the RASopathies - a group of genetic syndromes caused by germline mutations of genes encoding regulatory components of the Ras/MAPK pathway. This set of alterations includes: Noonan Syndrome, Costello Syndrome, neurofibromatosis type I, Legius Syndrome, autoimmune lymphoproliferative syndrome, capillary malformation / arteriovenous malformation (ALPS), LEOPARD, cardio-facial-cutaneous syndrome (CM-AVM) and gingival fibromatosis type I. Considering that all these mutations are associated with components of the RAS/MAPK pathway, the following are created: both overlap phenotypes - whose differential diagnosis is based on the identification of the genes involved ; as well as an association, although less strong than the one verified in somatic mutations, with the development of neoplastic diseases.This article reviews the clinical and molecular bases of each of these Syndromes and their association with the development of neoplasms.
Desde meados dos anos 80 que a via Ras/MAPK tem despoletado a atenção da ciência pela sua influência no controlo, proliferação, diferenciação e sobrevivência celulares. Deste modo, mutações nos genes que a constituem são causadoras de alterações significativas no organismo. Se, inicialmente, as mutações somáticas foram amplamente estudadas e associadas ao desenvolvimento de Neoplasias, mais recentemente foi estabelecida uma relação causal entre mutações germinativas activadoras da via e síndromes genéticas conhecidas. Com esta revisão pretende-se dar foco às RASopatias – grupo definido de síndromes genéticas causadas por mutações germinativas em genes que codificam componentes reguladores da via Ras/MAPK. Este grupo de situações inclui: Síndrome de Noonan, Síndrome de Costello, Neurofibromatose tipo I, Síndrome de Legius, Síndrome Linfoproliferativo Autoimune (ALPS), Mal-formação capilar/ mal-formação arteriovenosa (CM-AVM), Síndrome de LEOPARD, Síndrome Cardio-facio-cutâneo e Fibromatose gengival tipo I. Por todas estas situações terem por base uma desregulação da via RAS/MAPK, é natural que existam características fenotípicas sobreponíveis - cujo diagnóstico diferencial se baseia na identificação do(s) gene(s) envolvido(s); Também estabelecida é a associação, ainda que menos forte do que nas mutações somáticas, ao desenvolvimento de patologia neoplásica. Este artigo revê as bases clínicas e moleculares de cada um destes síndromes e a sua associação ao desenvolvimento de Neoplasias.
