No entanto, o apoio computacional ao experimento científico em larga escala encontra-se ainda incipiente e é considerado um grande desafio. Este trabalho tem o intuito de colaborar para as pesquisas nessa área, apresentando a arquitetura SciProvMiner, cujo principal objetivo é coletar proveniência prospectiva e retrospectiva de experimentos científicos fazendo uso de recursos Web semânticos para otimizar o processo de captura das informações de proveniência e aumentar o conhecimento do cientista sobre o experimento realizado. Como contribuições específicas do SciProvMiner, podemos destacar: - Desenvolvimento de um modelo para contemplar a proveniência prospectiva e retrospectiva como uma extensão do Open Provenance Model (OPM), que em sua forma original modela somente proveniência retrospectiva. - Especificação e implementação de um coletor de proveniência que utiliza a tecnologia de serviços Web para capturar ambos os tipos de proveniência segundo o modelo acima; - Desenvolvimento de uma ontologia denominada OPMO-e, que estende a ontologia Open Provenance Model Ontology (OPMO) de forma a modelar o conhecimento acerca da proveniência prospectiva além da retrospectiva já contemplada na OPMO e onde são implementadas as regras de completude e inferência definidas na documentação do modelo OPM. Estas regras aumentam o conhecimento do cientista sobre o experimento realizado por inferir informações que não foram explicitamente fornecidas pelo usuário e tornando possível a otimização do processo de captura de proveniência e a consequente diminuição do trabalho do cientista para instrumentalizar o workflow; - Especificação de um banco de dados relacional onde são armazenadas as informações de proveniência capturadas pelo coletor, que pode ser utilizado para ser consultado a respeito da proveniência explicitamente capturada, além de fornecer dadosparaas demais funcionalidades do SciProvMiner. / To provide historical scientific information to deal with knowledge loss about scientific experiment has been the focus of several researches. However, the computational support for scientific experiment on a large scale is still incipient and is considered one of the challenges set by the Brazilian Computer Society for 2006 to 2016 period. This work aims to contribute in this area, presenting the SciProvMiner architecture, which main objective is to collect prospective and retrospective provenance of scientific experiments, using ontologies and inference engines to provide useful information in order to increase the knowledge of scientists about a given experiment. We can highlight as specific contributions of SciProvMiner: - Development of a model that encompass prospective and retrospective provenance as an extension of the Open Provenance Model (OPM), which originally onlydeals with retrospective provenance. - Specification and implementation of a provenance collector that uses Web services technology to capture both types of provenance (prospective and retrospective) according to the above model; - Development of an ontology,named Extended OPMO-e, that extends the Open Provenance Model Ontology (OPMO) in order to model prospective provenance beyond the retrospective provenance already covered in OPMO and where are implemented inference and completeness rules defined in OPM documentation. These rules increase the knowledge of scientists on the experiment inferring information that were not explicitly provided by the user and making it possible to optimize the provenance capture mechanism and the consequent decrease on scientist work in order to instrument the workflow. - A relational database specification, where captured provenance information are stored. These information can be used to formulate queries about the provenance explicitly captured, besides provide data to other functionalities of SciProvMiner.

Toda modificação ocorrida em um experimento deve ser propagada para os workflows associados, os quais devem ser mantidos e evoluídos para o prosseguimento com sucesso da pesquisa. Um das forma de garantir este controle é através da gerência de configuração. Para que ela possa ser utilizada, é importante o armazenamento dos dados de execução e modelagem do experimento e workflows associados. Neste trabalho, utilizamos conceitos e modelos relacionados à proveniência de dados para o armazenamento e consulta destes dados. O uso da proveniência de dados traz alguns benefícios neste armazenamento e consulta, conforme veremos nesta dissertação. Assim, nesse trabalho é proposta uma arquitetura para gerenciar a evolução e manutenção de experimentos e workflows científicos, denominada E-SECO ProVersion. A motivação para a especificação e implementação da arquitetura veio a partir da realização de uma revisão sistemática e de um estudo para verificar características de manutenção e evolução em repositórios de workflows existentes. A partir destas análises, as principais funcionalidades da arquitetura foram definidas e detalhadas. Além disso, um roteiro com diretrizes de uso e provas de conceito utilizando workflows extraídos do repositório myEx-periment foram apresentados, com o objetivo de avaliar a aplicabilidade da arquitetura. / A scientific software ecosystem, in addition to other features, seeks to integrate all stages of an experiment, and commonly used scientific workflows to solve complex problems. Any changes that occurred in an experiment must be propagated to the associated workflows, which must be maintained and evolved for further successful research. One of the way to ensure this control is through configuration management. So that it can be used, it is important the storage of performance data and modeling of the experiment and associated workflows. In this study, we use the concepts and models related to the source of data for storage and retrieval of this data. Use the data source brings some advantages in storage and query, as we will see in this dissertation. Thus, this paper proposes an architecture to manage the development and maintenance of scientific experiments and workflows, called E-SECO ProVersion. The motivation for the specification and implementation of architecture came from the realization of a systematic review and a study to check maintenance characteristics and evolution in existing workflows repositories. From these analyzes, the main features of the architecture are defined and detailed. In addition, a roadmap with usage guidelines and proofs of concept using workflows extracted from myExperiment repository were presented in order to evaluate the applicability of architecture.

L’objectif de ce travail de thèse consistait à étudier le processus de formation d’une collection d’art, à travers l’exemple de la collection d’Alexandre Golitzine (1727-1807), en lien étroit avec le marché de l’art européen de la 2e moitié du XVIIIe siècle. Ce travail est basé sur l’analyse d’un corpus de documents archivistiques conservés en Russie, à Moscou. Il s’agit de la correspondance entretenue par Golitzine avec ses agents actifs sur le marché de l'art européen, ainsi que des listes d’œuvres, des quittances et des comptes inclus dans les lettres. Outre la correspondance, nous avons utilisé le catalogue de la collection d’Alexandre Golitzine, la Description, conservé aux archives de l'Ermitage à Saint-Pétersbourg. Dans la première partie de ce travail nous dressons un tableau général de la formation de la culture visuelle des élites russes au XVIIIe siècle. Celle-ci s’acquiert tant au cours de voyages formateurs en Europe, que grâce aux livres ou encore aux œuvres d’art importées en Russie. La création de l’Académie des beaux-arts à Saint-Pétersbourg est, quant à elle, une étape importante dans l’assimilation de l’art européen en Russie. La deuxième partie est consacrée au parcours du prince-collectionneur Golitzine et à la formation de sa collection grâce aux acquisitions de tableaux et de sculptures faites par son réseau d’agents en Europe, tout particulièrement, en Hollande, dans les états allemands, et en Italie. Nous étudions le processus de ces achats. L’étude du fonctionnement et de l’infrastructure de son réseau sert également d’observatoire pour un ensemble de pratiques courantes sur le marché de l'art. Puis, dans la dernière partie de ce travail nous présentons brièvement le catalogue et le contenu de la collection Golitzine, sans viser l’identification des œuvres aujourd’hui dispersées. Le catalogue nous permet de confirmer certaines informations obtenues dans la correspondance à propos des achats. Il nous renseigne davantage sur le goût artistique de Golitzine, qui s’avère être un collectionneur représentatif de son milieu. En effet, son goût s’inscrit dans les tendances de son époque et de son pays, et son réseau d’agents croise et intègre un vaste réseau « russe » sur le marché de l’art européen. Les résultats des recherches menées dans le cadre de cette thèse enrichissent notre connaissance des pratiques et des acteurs du marché de l’art en Europe au XVIIIe siècle, du réseau russe en particulier. Cette thèse nous permet également de mieux connaître la démarche collectionniste d’Alexandre Golitzine, son goût, la provenance de certaines œuvres de sa collection, ainsi que sa place dans l’histoire du collectionnisme russe. / The aim of this thesis was to study the process of formation of an art collection, through the example of the collection of Alexander Golitzine (1727-1807), that was closely related to the European art market of the second half of the 18th century.This work is based on the analysis of the private papers found in the Moscow archives in Russia. These are the correspondence of Golitzine with his agents in the European art market, as well as the lists of paintings and sculptures, some receipts and accounts accompanying the letters. Besides the correspondence, I have used the catalog of Alexander Golitzine’s collection, the Description, kept in the archives of the Hermitage in St. Petersburg.In the first part of this work I draw a general picture of the formation of the Russian elite’s visual culture in the 18th century. It was developed through educational journeys to Europe, through books and works of art imported into Russia. The creation of the Academy of Fine Arts in St. Petersburg was an important step in the assimilation of European art in Russia.The second part is devoted to the prince-collector Golitzine and the acquisitions of paintings and sculptures made with the participation of the agents’ network in Europe, especially in Holland, in the German states and Italy. I study the formation of his collection through the analysis of the process of acquisitions. The study of the structure of the agents network and its functioning provides an example of a common set of practices and procedures on the art market that time.Finally, in the last part of this work I briefly present the catalog and the content of Golitzine’s collection. However, for different reasons, I do not identify the art works. The catalog allows to confirm the information on purchases, obtained in the correspondence, and provides us with additional information on Golitzine’s artistic taste, which shows him as a representative collector of his time and his country. At the same time, his network of agents seems to be a part of a wider "Russian" network on the European art market. The results of the research conducted in this thesis enrich our knowledge of the practices and actors of the art market in Europe in the 18th century, of the Russian network in particular. The thesis provides a better understanding of Alexander Golitzine’s approach to collecting, his artistic taste, the provenance of certain art works, and his place in the history of Russian collecting.

Doctor en Ciencias, Mención Geología / Modificaciones del relieve provocados por procesos geológicos de gran escala como el alzamiento de cordilleras tiene importantes efectos en las condiciones climáticas y generan cambios significativos del paisaje. De esta forma, variaciones en las condiciones de temperatura y precipitación de una región afectan directamente la distribución, diversidad y composición de la vegetación. En la actualidad la dirección de flujo de los ríos en el sur de Sudamérica es principalmente hacia el oriente, sin embargo, aún no es claro cuál fue la dirección de las corrientes y las zonas de proveniencia en el pasado. Cambios en las direcciones de paleocorrientes ocurridos durante el Cenozoico en la Cuenca de Magallanes, junto con cambios de ambientes, pasando de marinos a transicionales y finalmente a ambientes continentales, procesos que fueron identificados en el sector de Sierra Baguales, al norte del Parque Nacional Torres del Paine, podrían vincularse con el levantamiento de los Andes Patagónicos, proceso que a su vez podría asociarse a cambios paleoclimáticos y paleoecológicos que habrían sido provocados por el efecto de sombra de lluvia y apertura del paso Drake durante el Oligoceno, cambios paleogeográficos que a su vez coinciden con modificaciones de las zonas de aporte de sedimentos a la Cuenca de Magallanes y la posición relativa de Península Antártica. El presente estudio evalúa cual fue el efecto de los procesos tectónicos como el levantamiento de los Andes Patagónicos, apertura del Paso Drake y cambios en las zonas de proveniencia. Se discute el vínculo entre la evolución de la Cuenca de Magallanes y la posición de la Península Antártica. Estos procesos fueron evaluados a partir de la evolución espacio-temporal de las paleocorrientes y el establecimiento de las zonas que aportaron detritos a la Cuenca durante el Cenozoico en Sierra Baguales, adicionalmente, junto con la evolución tectónica y sedimentológica del sector, se analiza la respuesta de la vegetación en términos de diversidad y composición, comportamientos analizados bajo un contexto de cambio climático global durante el Cenozoico donde especialmente se discute la respuesta de la vegetación frente a procesos de enfriamiento como el ocurrido durante el Oligoceno.

Magister Scientiae - MSc / Natural radioactivity studies have been carried out to study the textural characteristics, heavy mineral composition, provenance, sediment transport, and depositional environment of beach placer deposits. The naturally occurring radionuclides such as 232Th, 238U and 40K are used as the tracers of the mineralogical properties of beach sands, which reflect the geological characteristics such as transport and sorting processes and the depositional environment. The present work focuses on the radiometric characteristics of beach sand deposits along the west coast of South Africa. Beach sands samples were collected at the Melkbosstrand (MBS) and Ouskip (OSK) beach. The activity concentrations of these radionuclides were determined by high-resolution gamma-ray spectrometry using a high-purity germanium (HPGe) detector in a low-background configuration.

O Hemocentro São Paulo é responsável por manter um banco de dados com informações sobre cada doação ou tentativa de doação de sangue. No entanto, os dados desse banco de dados não possuem a qualidade requerida pelas ferramentas/técnicas de análise. Por essa razão, fica difícil utilizar tais dados para estabelecer relações sistemáticas entre as variáveis armazenadas. A principal contribuição desta tese é a descrição da proveniência para atributos selecionados usando critérios de classificação definidos por especialistas. Este trabalho mostra que é possível fazer investigações detalhadas usando a descrição dos dados sem a necessidade de alterar a estrutura do banco de dados. Durante o período de 1996 a 2006, 1.469.505 doadores foram responsáveis por mais de 2.8 milhões de doações. Após a descrição da proveniência, foram obtidos 252.301 doadores do sexo masculino e 133.056 doadores do sexo feminino e que atenderam aos critérios de inclusão usados nesta tese. Dos 385.357 doadores incluídos na análise, 21.954 (5,7%) tiveram suas doações adiadas devido a seus baixos níveis de hematócrito, 3.850 (1,5%) eram do sexo masculino e 18.104 (13,6%) do sexo feminino. Os resultados obtidos demonstram que, embora os intervalos de espera entre as doações de sangue sejam grandes entre os doadores do sexo feminino e masculino, as mulheres são recusadas mais cedo, por risco de desenvolver anemia, do que os homens. Aproximadamente 12,84% das mulheres e 1,21% dos homens desenvolveriam hematócrito baixo antes da sétima doação. Os dados sugerem que indivíduos com baixo nível de hematócrito devem esperar mais tempo antes de executarem a próxima doação. Portanto, é importante compreender se existe uma ligação entre a doação de sangue e a diminuição no nível de hematócrito, a fim de evitar resultados indesejáveis para os doadores de sangue. O modelo de proveniência apresentado nesta tese não foi definido de acordo com os modelos de proveniência genéricos já implementados. Esta tese apresenta um modelo de proveniência que foi capaz de acrescentar informações semânticas para adquirir conhecimento de um experimento in silico. Um dos principais objetivos foi desenvolver uma abordagem baseada em declarações, tentando responder a importantes questionamentos biológicos. O modelo descrito combina ricas informações em cada processo usando declarações, e se baseia no conhecimento de especialistas. Esta tese também utilizou estatística descritiva e Análise de Sobrevivência. Finalmente, com a validação do modelo em um domínio conhecido, é pretendido expandir esse método para outros sistemas de informação voltados para hemoterapia. / The São Paulo Blood Center is responsible to maintain a database with information on each donation. However, this database does not have the quality required by techniques of analysis. For this reason, it is difficult to use it directly to establish systematic relationships between the variables. The main contribution of this paper is a provenance description of attributes selected using classification criteria defined by specialists. We show that it is possible to make detailed investigations using the data description without the need to change the structure of the database. During 1996 2006, 1,469,505 donors were responsible for more than 2.8 million of donation. After the provenance description, we obtained 252,301 male and 133,056 female that met our inclusion criteria. Of the 385,357 donors included in the analysis, 21,954(5.7%) were deferred due to low hematocrit, 3,850(1.5%) were males and 18,104(13.6%) were females. Our results show that, although the intervals between donations for female and male donors are wider, women presented anemia earlier than men. Approximately 12,84% of the females and 1,21% of the males would develop low hematocrit before the 7th donation. Our data suggest that individuals with low hematocrit level should wait longer before the next donation. Therefore, it is important to understand if there is a connection between blood donation and decrease in hematocrit level in order to prevent undesirable outcomes to blood donors. The provenance model presented here was not defined according to the generic provenance models already implemented. This thesis presents a provenance model that is able to add semantic information to acquire knowledge of an in silico experiment. One of the main purposes is to develop an approach based on declarations in order to answer biological questions. The provenance model described in this paper combines rich information for each process using the declarations, each having expert knowledge as a basis. To evaluate this provenance model we use descriptive statistics and Survival Analysis. Finally, with the validation of the model in a known domain, we intent to apply and validate this provenance model to other hemotherapy information systems.

The samples of garnets used in this study come from clastic sediments from the drillcores Tř-1 and T-31, selected localities of the České středohoří Mountains and garnet-bearing ultramafic rocks sampled by the drillcore T-7. The contents of the major and some minor elements were determined by an electron probe microanalyzer. The garnets from the sediments were divided into 3 groups according to the contents of the end-members: 1) pyrope-, 2) almandine - pyrope- and 3) grosular - almandine-rich. Garnets from the drillcore T-7 were classified according to individual rock types in which they occurred: lherzolite, hazburgite, pyroxenite, eclogite and granulite. Chemical analyzes of garnets displayed the presence of positive correlations Cr vs. Ca vs. Ti Mn in pyrope grains. The contents of trace elements in garnets were studied by an LA-ICP-MS. After normalization to the CI-reservoir, garnets most often show lherzolite profiles of rare earth elements. Garnets of intense red and purple colors show slightly sinusoidal REE profiles. Inclusions enclosed in garnets were studied by a scanning electron microscope. If their dimensions allowed, the major and minor elements were determined by electron microanalysis for inclusions. Inclusions of amphiboles in association with spinel group minerals, carbonates and...

Svenskarnas klädkonsumtion har nästan fördubblats under de 30 senaste åren. Den stora anledningen är att kläderna blivit allt billigare, eftersom majoriteten produceras i låglöneländer. Långa värdekedjor, bristande kvalitetskontroll och dåliga arbetsförhållanden är exempel på utmaningar som utlandsproduktion för med sig. Etisk produktion och hållbarhet har aldrig varit mer aktuellt än det är idag och det är något som både kunder och företag värderar och eftersträvar. Frågan är om textilproduktionen i Sverige och framför allt trikåproduktionen som denna studie fokuserar på, har möjlighet att utvecklas i takt med den ökade medvetenheten kring hållbarhet, etisk konsumtion och transparent produktion. Syftet med studien är därför att undersöka förutsättningar och fördelar med trikåproduktionen i Sverige genom att ta reda på om det finns hållbarhetsaspekter, konkurrensfördelar och intresse bland svenska trikåföretag att producera i Sverige. Begreppen reshoring, proveniens och hållbarhet är studiens utgångspunkt utifrån vilka en litteraturstudie byggdes upp. En trianguleringsmetod användes som innefattar såväl en kvantitativ enkät samt två kvalitativa semistrukturerade djupintervjuer med företagsledare för två trikåföretag som helt eller delvis har produktion i Sverige. Resultatet visade att det finns utrymme för trikåproduktion i Sverige eftersom efterfrågan och intresset från svenska företag är stort. Däremot finns det flera utmaningar. Lönsamhet, brist på kompetens samt kundernas okunskap och ovilja att betala för produkter som är tillverkade i Sverige är några av svårigheterna. Det visade sig också att produktion i Sverige är komplext och kanske inte alltid så bra som det låter. Märkningen made in kan missrepresentera var en produkt verkligen är tillverkad, eftersom det endast anger var produkten har monterats. Kunderna vill gärna ha ett enkel t svar på en komplicerad problematik, vilket många företag är snabba att bistå. Studien ger inspiration till ytterligare forskning kring svensk tekoindustri samt till svenska trikåföretag som överväger att förlägga produktion till Sverige. Studien kan också öka medvetenheten hos kunder gällande sin roll i den textila värdekedjan. / The clothing consumption has almost doubled in the last 30 years in Sweden. The main reason is that clothes have become cheaper since the majority are produced in low-wage countries. Long value chains, lack of quality control and poor working conditions are examples of challenges that offshore production brings. Ethical production and sustainability have never been more relevant than it is today and it has become something that customers as well as companies value and strive for. The question is whether Swedish textile production, and the knitwear production which this study will focus on, have the opportunity to develop as the awareness of sustainability, ethical consumption and transparent production increases. The aim of the study is therefore to investigate the conditions and advantages of Swedish knitwear production, and to find out whether there are sustainability aspects, competitive advantages and interest among Swedish knitwear companies to produce in Sweden. Reshoring, provenance and sustainability are the starting points of which the literature study is built up. A triangulation method was used which includes both a quantitative survey and two qualitative in-depth interviews with company executives for two knitwear companies that have full or partly production in Sweden. The result showed that there is room for Swedish knitwear production, because of the demand and interest from Swedish companies. There are however several challenges. Profitability, lack of competence, customers ignorance and unwillingness to pay for Swedish-made products are some of the difficulties. The study shows that production in Sweden is more complex than expected and that it may not always be as good as it sounds. The label made in can misrepresent where a product actually is made, since it only indicates where the product has been assembled. However, customers would like a simple answer to a complicated problem, which many companies are quick to give. The study contributes with new knowledge about the Swedish textile industry and with valuable information to knitwear companies that consider to reshore their production. The study may also increase the awareness of Swedish customers regarding their role in the textile value chain.
