Le district aurifère de Meliadine se situe à 25 kilomètres au nord de Rankin Inlet, Nunavut (Canada), dans la ceinture archéenne de roches vertes de Rankin Inlet. L’assise rocheuse est composée de roches sédimentaires métamorphosées au grade des schistes verts incluant des Formations de Fer Rubanées (FFR) intercalées avec des roches mafiques. La minéralisation aurifère est distribuée le long de la faille Pyke. Des FFR abritent la minéralisation aurifère composée de veines de quartz riches en sulfures. Sept échantillons de till ont été prélevés parallèlement au sens de l’écoulement glaciaire à l’indice Mustang, le long d’un transect de 2 km. Deux échantillons ont été collectés en amont de l’indice et cinq dans le train de dispersion. La composition de la magnétite, de la tourmaline, de la scheelite, de l’arsénopyrite et de la galène a été investiguée par microsonde électronique et par ablation laser et spectrométrie de masse à plasma à couplage inductif. La composition chimique de ces minéraux indicateurs provenant des dépôts est comparée avec celle des grains des échantillons de tills. La signature chimique de la magnétite des FFR est plus riche en Al que la signature de la magnétite magmatique et métamorphique, qui elle est plus riche en V. Cependant elle se confond en partie avec celle de la magnétite hydrothermale. Des grains de tourmaline avec un profil de terres rares plat avec anomalie positive en europium sont présents dans des veines de quartz-carbonate des dépôts et dans certains échantillons de till en aval de l’indice Mustang. Des grains de scheelite avec un profil de terres rares en cloche et une anomalie négative en europium sont retrouvés à l’indice Mustang ainsi que dans certains échantillons en aval de l’indice. L’abondance des grains d’or ainsi que la scheelite et la tourmaline portant la signature géochimique des dépôts de Meliadine permettent de détecter l’indice d’or Mustang partiellement érodé par les glaciers. / The Meliadine Gold District is located about 25 kilometres north of Rankin Inlet, Nunavut (Canada), in the Archean Rankin Inlet greenstone belt. The bedrock is composed of greenschist facies metamorphic sedimentary rocks including Banded Iron Formations (BIF), interbedded with mafic volcanic rocks. Auriferous mineralization is distributed along the Pyke fault. Iron formations host the gold mineralization composed of sulfide-rich mesothermal quartz veins. Gold is mainly disseminated in BIF and quartz-carbonate veins. Seven till samples were collected parallel to the direction of ice flow at the Mustang showing, along a 2 km transect. Two are located up-ice and five down-ice in the dispersal train. The composition of magnetite, tourmaline, scheelite, arsenopyrite and galena has been investigated by Electron Probe Micro-Analyser and Laser Ablation Inductively Coupled Plasma Mass Spectrometry. The chemical composition of these indicator minerals in the deposits is compared with the composition of grains extracted from the till samples. Magnetite from BIF is enriched in Al and bears chemical similarities with hydrothermal magnetite, whereas magnetite from magmatic and metamorphic sources has a higher content in V. Tourmaline from quartz-carbonate veins hosted by mafic rocks is characterised by a flat Rare Earth Elements (REE) pattern with a positive europium anomaly also found in tourmaline from till samples down-ice of the Mustang showing. Scheelite with a bell-shape REE pattern and a negative europium anomaly from the Mustang showing is also found in till samples within the dispersal train. Gold grain abundance, as well as the signature of scheelite and tourmaline reflecting the gold deposits allow detecting the partially eroded gold mineralization.

This study focuses on orthodoxy and mysticism in the religious thought of Shaikh Mul,tammad ibn Tahir al-Fattani (914/1508-986/1578), a sixteenth century Sunui Rohra scholar. Islam had persistently presented two faces: one that was shari ah­ minded and concerned with the outward, socially cognizable behaviour and anothE'r mystkal-minded, concerned with the inward, personal life of the individual. The former was the domain of the "ulama", whereas the Sufi pirs accepted the care of the latter. While there were always those who accepted the one face of Islam as genuine and mistrusted the other or even regarded it as spurious, Shaikh al-Fattani succeecded in marrying the two. He was at once both a mystic pir and an orthodox religious scholar. A biography of Mul}ammad ibn Tahir al-Fattani based on the previous works is attempted with the aim being to collect the factual information pertaining directly to the details of his life. The last years of Shaikh al-F'attani's life were devoted to his reform involvement in his community and particularly to the removal of the Mahdawiyyah thoughts of Sayyid Muhammad Jawnpuri)who had declared himself the promised Mahdi. Against this backdrop of the life account of al-Fattani elements of orthodoxy and mysticism are identified in his scholarly works. Best known for his work Majma bihar al-anwar fi gharaib al-tanzil wa lataif al-akhbir, all the extant works of the Shaikh are discussed. To understand tbe subject within the context of his ethnic identity, aspects of the Bohra community are studied . lt is shown that their occupation as merchants and a history that emphasised their ancient link to the faith of Islam were some of the factors that shaped their group identity. Religious affiliation of the Bohras is explored in detail and after examining the various religious groupings it is evident that the principal communities amongst them differ substantially in their belief systems. Muslims of Sunni Bohra descent are to be found in South Africa. The Sunni Bohra community in general and their ulama in particular are today constantly challenged to not only be devoted to orthodoxy but to sufi doctrine and discipline as well. / Religious studies / D.Litt. et Phil.

The primary objective of this study was to estimate the impact that an increase in recreational expenditures, resulting from water quality improvements of Klamath Lake, would have upon the Klamath County economy. As the sales of the economy expand to serve the needs of the recreationists, real benefits will be forthcoming to the businesses and households of the county in the forms of more business and higher incomes. To estimate the total impact of the increased volume of recreational expenditures that may be made in the economy, the economic relationships of the local economy had to be determined. Primary data were collected from business firms in the county to construct an input-output model of the county's economy. The level of recreational expenditures that would be made in the county as the water quality of the lake improved were estimated. This was done for two different stages of water quality improvement. The estimated levels of recreational expenditures were then analyzed within the input-output framework to estimate the total increase in the sales of the economy and to estimate the increase in income of households in the county. / Graduation date: 1971

La construction de cartes de génomes consiste à baliser les chromosomes par des repères : les marqueurs. Plus une carte est dense en marqueurs régulièrement espacés, plus elle est informative et donc plus les applications ultérieures sont nombreuses. Parmi les différentes stratégies de cartographie, celle exploitant les hybrides d'irradiation dite carte RH, présente de nombreux avantages. Ainsi, des marqueurs polymorphes tels que les microsatellites, utiles pour les analyses de liaisons génétiques et des marqueurs de gènes, polymorphes ou non polymorphes permettant d'établir des cartes comparées avec d'autres génomes et définir des zones de conservation ou de rupture de synténie, peuvent être localisés sur une carte RH. Ces cartes comparées sont utiles non seulement pour l'identification de gènes d'intérêts mais également pour l'étude de l'évolution des génomes. Parmi les nombreux vertébrés d’intérêt, nous nous sommes particulièrement attachés à la construction de cartes RH de poissons et de cichlidés en particulier. Ceux-ci constituent en effet un modèle génétique très intéressant du point de vue économique et évolutif. La réalisation de cartes des génomes de plusieurs poissons devrait aider à l'identification de gènes impliqués dans des traits phénotypiques ou pathologiques voire même des marqueurs liés aux stress et à la reproduction. Mon travail de thèse a consisté à construire une carte du génome du bar, un panel RH de tilapia et la carte RH attenante qui a été utilisée dans la phase finale de l’assemblage des données de séquence du génome de Tilapia. Par ailleurs nous avons construit un panel RH d’esturgeon et un autre d’huitre. La cartographie du génome de tilapia, réalisée dans le cadre d’un consortium international, nous a donné un accès privilégié aux données de séquences des génomes de cinq cichlidés (O. niloticus, P. nyererei, H. burtoni, N. brichardi et M. zebra) et nous a permis de participer à l’annotation de ces séquences génomiques en nous intéressant plus particulièrement à l’identification des répertoires des gènes codant pour les récepteurs olfactifs (OR) et les récepteurs connus sous le vocable de TAAR pour ‘ Trace Amine-Associated Receptors’. C’est ainsi que nous avons identifié et caractérisé 158, 88, 90, 69, 102 gènes OR et 45, 19, 23, 12, 20 gènes TAAR dans les génomes de ces cinq poissons (O. niloticus, P. nyererei, H. burtoni, N. brichardi et M. zebra) / The construction of genome maps consists in placing tags, called markers, on the chromosomes. The denser in evenly spaced markers is a map, the more it is informative, leading to the development of more future applications. Among the different mapping strategies, those using radiation hybrids (RH) have numerous advantages. Indeed, polymorphic markers such as microsatellites, useful for linkage analyses, as well as gene markers, polymorphic or not and allowing comparative mapping with other genomes and definition of synteny breaks and conservation, can be localized on a RH map. Not only these maps are useful to identify genes of interest but they are also essential tools to study genome evolution. Among numerous vertebrates of interest, we constructed RH maps of fishes and cichlids in particular. Indeed these fishes constitute interesting genetic models from economical and evolution points of view. Having genome maps of several of these fishes would help to identify genes implicated in phenotypical or pathological traits, or even markers linked to stress and reproduction. My thesis work consisted in the construction of a genome map of the sea bass, a tilapia RH panel and its RH map, a sturgeon RH panel as well as an oyster RH panel. The tilapia map was used for the assembly of the sequencing data of the tilapia genome. Thanks to this last work realized with an international consortium we had a privileged access to the sequencing data of five cichlid genomes (O. niloticus, P. nyererei, H. burtoni, N. brichardi and M. zebra). We then participated to the annotation of these genomic sequences. In particular we have identified and characterized the olfactory receptor gene (OR) repertoires and of the trace amine-associated receptor (TAAR) gene repertoires of these five cichlids. Which are then made of 158, 88, 90, 69, 102 OR genes and 45, 19, 23, 12, 20 TAAR genes respectively.

Emoções faciais desempenham um papel fundamental nas relações interpessoais humanas. Certas doenças psiquiátricas podem se caracterizar por déficits no reconhecimento das emoções. Nesse contexto, o presente projeto faz parte de um projeto maior que visa a desenvolver um jogo sério para auxílio ao diagnóstico e treinamento no reconhecimento de expressões faciais utilizando grafos And-Or para representação de emoções. Este projeto de mestrado define, implementa e avalia uma abordagem que gera caricaturas de várias emoções faciais (satisfação, tristeza, surpresa, medo, aversão, raiva e neutra) a partir de imagens de treinamento. Foi desenvolvida uma metodologia de processamento de imagens que localiza pontos de controle faciais em imagens reais de pessoas expressando as diferentes emoções, e aprende as variações de todos os pontos de controle, da face neutra para uma determinada emoção, para caracterização das expressões faciais. Para poder comparar a fidelidade da representação da emoção desejada nas imagens geradas, com respeito a uma abordagem anterior (que utiliza antropometria e FACS - Facial Action Coding System), um experimento com voluntários foi conduzido. Os resultados mostraram que a taxa de reconhecimento das imagens geradas com a metodologia proposta neste projeto, em relação às imagens geradas com a metodologia anterior, foi inferior em cinco emoções (medo, raiva, satisfação, surpresa e tristeza), igual para uma emoção (neutra) e superior para uma emoção (aversão). Para a emoção de aversão, cuja taxa de reconhecimento foi superior na abordagem proposta neste projeto, conseguiu-se aprender variações significativas de pontos de controle que não estão presentes nas unidades de ação que o FACS prevê para essa emoção. Esses dados sugerem que a proposta de aprender as variações de todos os pontos de controle da face pode ajudar em representar melhor as emoções faciais. Foram identificadas as possíveis causas para as taxas de reconhecimento inferiores das cinco emoções citadas, tanto na seleção da amostra de treinamento quanto nas etapas de processamento de imagens, as quais podem ser aperfeiçoadas a fim de melhorar a geração das caricaturas. Portanto, os resultados indicam que a abordagem apresentada é promissora, uma vez que considera todos os pontos de controle identificados em imagens reais e que o aperfeiçoamento de algumas fases do processo pode gerar caricaturas mais próximas das expressões reais, considerando diferentes intensidades das emoções / Facial emotions play a key role in human interpersonal relationships. Some psychiatric disorders may be characterized by deficits in recognizing emotions. In this context, this project is part of a major project that aims to develop a serious game to aid diagnosis and training in the recognition of facial expressions using And-Or graphs to emotions representing. This master\'s project defines, implements and evaluates an approach for generating caricatures of facial emotions (satisfaction, sadness, surprise, fear, disgust, anger, neutral) from training images. An image processing method that locates facial points in facial expression images was developed, and learns the variations of all facial points, from neutral face to a particular emotion for facial expression characterization. In order to compare the fidelity representation of the desired emotion in images generated with respect to anterior approach (using Anthropometry and Facial Action Coding System FACS), an experiment with volunteers was conducted. The rate recognition results showed that images generated with the proposed approach, compared to previous approach, were lower in five emotions (fear, anger, satisfaction, surprise and sadness), same to an emotion (neutral) and higher to an emotion (disgust). For disgust emotion, it was possible to learn significant variations of facial points that are not present in the action units that FACS provides for that emotion. This data suggests that the proposal for learning the variations of all facial points may help the facial emotion characterization. Possible causes for the lower rates were identified, both in the selection of training sample images and steps of image processing, which can be optimized in order to enhance the generation of caricatures. Therefore, the results indicate this approach is promising, since considers all facial points, and the improvement of some stages of the process can generate closest caricatures of real expressions, considering different intensities of emotions

The theme is part of the public budget problem in Brazil - object of theoretical revision in recent years, in the face of the progressive constitutionalization of the presuppositions of its understanding, in what can be called Due Budget Process. In this perspective, the finances of the State should reflect the priority public constitutional policies and the optimization of the administrative activity, as well as the result of a wide democratic discussion. In addition, it is necessary to discuss the binding effectiveness of budget laws in the period of their validity, which requires valid reasoning for hypotheses of change or contingency. Legitimate alternatives are presented that allow the success of judicial intervention in Public Finance when there is a flagrant violation of the legal order. In addition, the extrajudicial action of the Public Prosecutor's Office allows the resolution of constitutional conflicts with more speed and effectiveness. On the other hand, repressive action and judicial correction are indispensable tools for guaranteeing the community in all cases where preventive action is not successful. The work was developed through bibliographical and documentary research, being consulted publications referring to doctrine and jurisprudential documents. / O objetivo deste estudo ?? apresentar as possibilidades de interven????o jurisdicional no or??amento estatal, especialmente no que toca ?? contribui????o do Minist??rio P??blico para a efetiva????o de direitos fundamentais, por meio da interven????o jurisdicional nas finan??as p??blicas.

Tower Mountain Caldera is the main feature of an Oligocene volcanic field located in the Umatilla National Forest, eastern Oregon. It is perfectly suited to investigate models of rhyolite petrogenesis as all of the important rock components for evaluating generation models are present in a single location and thus are presumably related; basalts, intermediate igneous rocks (which consist of older plutons and younger volcanic rocks, which are ~coeval with rhyolites), metamorphic basement rocks of significant grade, and rhyolites of varying composition. The formation of the caldera produced the Dale Tuff, which comprises the intra-caldera and outflow facies. 40Ar/39Ar dating places the age of the tuff at 32.66 ± 0.36 Ma. Post-caldera rhyolites erupted along apparent ring fractures and elsewhere. Radiometric U-Pb dating of zircons from three of these rhyolites yielded ages of 32.167 ± 0.020 Ma (#CH07a), 31.798 ± 0.012 Ma (#TM5), and 31.426 ± 0.016 Ma (#CH08a). All rhyolites at Tower Mountain range from low to high silica varieties. Some of the post-caldera rhyolites are chemically similar to the Dale Tuff, such as sample CH07a, and have compositions typical of rhyolites of calc-alkaline volcanic centers (I-type rhyolites), while others are similar to A-type rhyolites (CH08a and TM5). The ages indicate that the calc-alkaline rhyolites were followed by the A-type rhyolites. The petrogenetic relationships between the various rocks types were evaluated. Partial melt modeling based on experimental melts produced from crustal material indicates that batch partial melting of metamorphosed high silica crustal material modified by the addition of more primitive mafic material by assimilation/contamination is the most likely source for the Tower Mountain rhyolites.

This thesis describes the archaeological site content and integrity of the Copeland site (35BE90) in Corvallis, Oregon. The Copeland site is owned by the Benton County Historical Society and is the future home of the Benton County Historical Museum. In 2001, an Oregon State University archaeological field school was conducted to test for the presence of the residential houses and commercial businesses that once occupied the Copeland site. The archaeological excavation revealed the presence of both the residential and commercial usage that occurred at the Copeland site. Excavation also revealed that while the integrity of the site has been disturbed by commercial activities the integrity has not been completely destroyed. Finally, recommendations are made concerning further archaeological exploration of the site. / Graduation date: 2006

The continental terrace west of Oregon between 43° 50'N and 44° 40' N latitude is 50 to 55 miles wide. It consists of a continental shelf, 16 to 35 miles wide, and a continental slope, 16 to 37 miles wide. The eastern portion of the shelf is a smooth, sediment covered area that slopes very gently west. The western portion of the shelf contains four rocky bank areas. The banks are topographically irregular and appear to be of structural origin. West of the banks the shelf edge occurs at depths of 71 to 90 fathoms. The continental slope extends from the edge of the shelf to the abyssal plain at depths of 1530 to 1610 fathoms. A smooth upper slope of less than three degrees extending to depths of 117 to 250 fathoms occurs north and south of Heceta Bank. West of Heceta Bank the upper slope is formed by a scarp that slopes 10° to 16° to 560 to 725 fathoms. West of the upper slope there is an area of irregular topography, including benches, hills and scarps, which extends to depths of 380 to 1100 fathoms. The lower part of the slope is formed by a north-striking scarp which is 3000 to 6000 feet high and slopes 04° to 15°. The bathymetry indicates that the continental slope was formed by step-type, block faulting. Sediments form a thin surface layer over much of: the terrace. Detrital sand, similar to the coastal sand, covers the shelf from the shoreline to approximately 50 fathoms. The deeper areas on the shelf and upper part of the slope are covered by glauconitic sands and silts on the topographic highs and olive green, clayey silts in the topographic lows. The intermediate and lower portions of the slope are blanketed with olive-green, clayey silt. In these sediments the sand fraction, which generally comprises less than five percent of the sample, is composed chiefly of diatoms, Foraminifera, Radiolaria, and sponge spicules. Sands are also present on the intermediate and deep portions of the slope. Dredge hauls west of Newport obtained sand composed mainly of detrital grains which may have been derived from an underlying friable sandstone. Thin layers of sand occur in cores from other portions of the slope. These sands may have been derived by down slope movement of sediment from the upper slope and the shelf. Sedimentary rocks of Upper Miocene and Pliocene age crop out on the shelf banks and on the continental slope. The banks consist of a sequence of diatomaceous, clayey siltstones with interbeds and concretions of calcareous siltstones. Glauconite sandstone, gray wacke sandstone, and limestone breccia are exposed along with the siltstone, on the northern end of Heceta Bank. Most of the rocks obtamed from the slope are similar to those from the shelf. Friable, wacke sandstone is exposed on the slope west of Newport. Foraminifera, the sand fraction compositions, and textural analyses all indicate that the sediment forming the siltstones from the shelf were deposited at lower littoral to lower bathyal depths. The sediments forming the rocks were deposited in one or more sedimentary basins during the Miocene and Pliocene. The subsidence continued until the. Late Pliocene when the area began to rise. The area was uplifted as much as 1000 fathoms by the Late Pleistocene when the shelf was eroded by transgressions and regressions resulting from sea level changes. The last rise in sea level resulted in the erosion of the shelf to its present form and the deposition of a thin layer of sediment. Sand is presently being deposited on the shallow areas adjacent to the continent, and silt and clay are being laid down on the slope and the sheltered areas of the outer shelf. / Graduation date: 1965
