This paper deals with the effect of the MR pulse sequences on the temperature of the measured object. The theoretical part is dedicated to basic principle of magnetic resonance, the selected pulse sequences and risks that are connected with MRI. There is also described the draft of the testing phantom and information about the measurement and record of temperature during MR measurement. In the experimental part the effect of RF coils, pulse sequences and parameters of pulse sequences are tested on drafted phantom with experimental MR device located at the Institut of Scientific Instruments of the AS CR in Brno. These findings are then tested on live laboratory mouse. All results are analyzed and used as default data for developed simulation program.

We consider a variety of types of vertex sequences, which are defined in terms of a requirement that the next vertex in the sequence must meet. For example, let S = (v1, v2, …, vk ) be a sequence of distinct vertices in a graph G such that every vertex vi in S dominates at least one vertex in V that is not dominated by any of the vertices preceding it in the sequence S. Such a sequence of maximal length is called a dominating sequence since the set {v1, v2, …, vk } must be a dominating set of G. In this paper we survey the literature on dominating and other related sequences, and propose for future study several new types of vertex sequences, which suggest the beginning of a theory of vertex sequences in graphs.

THE PARADOX Basin is a northwest-southeast trending intracratonic basin that formedin southwestern Colorado, southeastern Utah and adjacent parts of Arizona and New Mexicoduring the late Paleozoic Era. During rise of the adjacent Uncompahgre Uplift (Ancestral RockyMountains) the rapidly subsiding basin was filled with over 2000 m of Permo-Pennsylvaniansediments. Stacked depositional sequences accumulated in three roughly parallel facies belts: anortheastern clastic belt (adjacent to uplift), a central salt and black shale belt, and asouthwestern carbonate belt. Over 400 million barrels of oil have been extracted from upperParadox (Desert Creek and Ismay) carbonates in the southern Blanding Subbasin (Greater AnethField) since 1956. The sedimentology and sequence stratigraphy of Paradox Shelf strata on thewalls of the San Juan River gorge and in the subsurface Aneth Buildup are well documented.Less well documented are the stratigraphy and facies architecture of basinward extensions ofupper Paradox sequences in the northern part of the Blanding Subbasin.Detailed analysis of the lower and upper Desert Creek and lower and upper Ismay 4thordersequences from three cores (Long Point, Lewis Road, Cedar Point) demonstrate theexistence of distinctive basinward depositional trends. Compared to sequences exposed on theParadox Shelf (San Juan River outcrops) and the Aneth Buildup, sequences in the more distalnorthern Blanding Subbasin are thinner, are dominated by muddy carbonate facies, displaylimited occurrences of porous phylloid-algal and oolitic carbonates, contain thicker, morecomplete occurrences of black shale, and possess distinctive suites of lowstand facies (quartzsandstone on the shelf, bedded and nodular evaporates in the basin). Vertically, the four 4th-ordersequences display 2nd-order progradation of the Paradox Shelf through Desert Creek and Ismaytime. Carbonate-starved sequences (4th order) and parasequences (5th order) comprised of muddominatedfacies are succeeded upward by thicker, more grain-rich sequences andparasequences. The implications for the petroleum system relative to established oil and gasfields is that conventional reservoir rock facies are rare, except in small, isolated buildups.Meteoric diagenesis associated with 4th-order lowstands of sea level has reduced overallpermeability. Lowstand conditions also promoted limited precipitation of pore-occludingevaporite cement. The maximum-flood Chimney Rock, Gothic and Hovenweep shales arethicker and contain a more complete succession of basinal cycles than updip occurrences of thesepetroleum source rocks. A suite of samples from the Gothic Shale from the Cedar Point coreindicate higher burial maturity (kerogen has mostly been converted to gas) compared to valuesderived from the outcrop belt and more proximal subsurface samples.

A coccidiose aviária é uma doença entérica causada por protozoários parasitas do gênero Eimeria. Visando uma maior compreensão dos mecanismos moleculares envolvidos na regulação do ciclo de vida dos parasitas, foram geradas 15.000 seqüências expressas (ORESTES) para cada uma das três espécies mais importantes: E. tenella, E. maxima e E. acervulina. O presente trabalho consistiu no desenvolvimento de componentes de anotação automática de seqüências para o sistema EGene, plataforma previamente desenvolvida pelo nosso grupo (Durham et al. Bioinformatics 21: 2812-2813, 2005) para a construção de processamentos encadeados (pipelines). Estes componentes foram utilizados para a construção de pipelines de anotação automática de seqüências-consenso obtidas a partir da montagem dos ORESTES de Eimeria spp. A anotação consistiu na identificação dos genes e atribuição da função dos respectivos produtos protéicos, baseando-se em um conjunto de evidências. As seqüências também foram classificadas e quantificadas utilizando-se um vocabulário controlado de termos de ontologia gênica (GO). / Avian coccidiosis is an enteric disease caused by protozoan parasites of the genus Eimeria. Aiming at obtaining a better understanding of the molecular mechanisms that regulate the life cycle of the parasites, our group generated 15,000 expressed sequences (ORESTES) for each one of the three most important species: E. tenella, E. maxima and E. acervulina. In the present work, we report the development of a set of components for the automated sequence annotation through EGene, a platform for pipeline construction previously described by our group (Durham et al. Bioinformatics 21: 2812-2813, 2005). These components were used to construct pipelines for the automated annotation of assembled sequences of ORESTES of Eimeria spp. The annotation process consisted in the identification of genes and the corresponding protein function based on a set of evidences. The sequences were also mapped and quantified using a controlled vocabulary of gene ontology (GO) terms.

Um dos aspectos fundamentais para o desenvolvimento deste tipo de aplicação é a questão da Sensibilidade ao Contexto, que permite a uma aplicação adaptar o seu funcionamento conforme a situação na qual o usuário se encontra no momento. Com esta finalidade, diversos autores apresentaram definições formais sobre o que é um contexto e como representá-lo. A partir desta formalização começaram a ser desenvolvidas técnicas para análise de dados contextuais que propunham a realização de predições e inferências, entre outras análises. Esta dissertação especifica um framework denominado SIMCOP (SIMilar Context Path) para a realização da análise de similaridade entre sequências de contextos visitados por uma entidade. Este tipo de análise permite a identificação de contextos semelhantes com a intenção de prover funcionalidades como a recomendação de entidades e/ou contextos, a classificação de entidades e a predição de contextos. Um protótipo do framework foi implementado, e a partir dele foram desenvolvidas duas aplicações de recomendação, uma delas por um desenvolvedor independente, através do qual foi possível avaliar a eficácia do framework. Com o desenvolvimento desta pesquisa comprovou-se, conforme demonstrado nas avaliações realizadas, que a análise de similaridade de contextos pode ser útil em outras áreas além da computação ubíqua, como a mineração de dados e os sistemas de filtragem colaborativa, entre outras áreas, onde qualquer conjunto de dados que puder ser descrito na forma de um contexto, poderá ser analisado através das técnicas de análise de similaridade implementadas pelo framework. / The Ubiquitous Computing, that studies the ways to integrate technology into the people’s everyday life, is an area that has been growing in recent years, especially due to the development of technologies such as mobile computing. A key for the development of this type of application is the issue of context awareness, which enables an application to self adapt to the situation in which the user is currently on. To make this possible, it was necessary to formally define what is a context and how to represent it . From this formalization, techniques for analyzing contextual data have been proposed for development of functions as predictions or inferences. This paper specifies a framework called SIMCOP (SIMilar Context Path ) for performing the analysis of similarity between sequences of contexts visited by an entity. This type of analysis enables the identification of similar contexts with the intention to provide features such as the recommendation of entities and contexts, the entities classification and the prediction of contexts. The development of this research shows that the contexts similarity analysis can be useful in other areas further the ubiquitous computing, such as data mining and collaborative filtering systems. Any data type that can be described as a context, can be analyzed through the techniques of similarity analysis implemented by the framework, as demonstrated in the assessments.

Since text plans and the narrative and descriptive sequences have an important role in textual organization, we established as a general objective to verify the organization of text plans and the role of narrative and descriptive sequences in João Antônio’s tales and specific objectives to identify, describe, analyze and discuss the text plans and textual sequences narrative and descriptive. In order to develop this study, we sought theoretical foundations offered by Language Textual, more specifically the Textual Analysis of the Discourses (ADAM, 2011; Marcuschi, 2005; 2008 2013; KOCH, 2011; 2013; 2014; Marquesi, 2004). To treat type and gender, we leaned on the theoretical basis of Travaglia (2004; 2007a; 2007b; 2009; 2014), Bakhtin (2011[1979]) and Marcuschi (2005); to conceptualize text plan and textual sequence we fundamented ourselves in Adam (2011) and Cabral (2013); as the textual narrative sequence, we seek Adam's studies (2011 ) and to conceptualize the descriptive and descriptive textual sequences, we make use of the research developed by Marquesi (2004; 2012;) and Adam (2011). The corpus of this study consists of seven short stories of João Antônio published in Reality magazine between 1967 and 1968. Among these tales we had chosen to present the analysis of two, by way of example. The results show that both the descriptive sequences and the narrative sequences, besides competing for a plan establishment, contribute themselves to give the fictional universe described by João Antônio a peculiar sense of reality, which marks the confluence between literature and journalism featuring the texts of the author published in the above mentioned magazine / Esta dissertação, que se insere na linha de pesquisa Texto e discurso nas modalidades oral e escrita, tem como tema os planos de texto e as sequências textuais narrativas e descritivas em contos de João Antônio publicados na revista Realidade entre 1967 e 1968. Uma vez que os planos de texto e as sequências narrativas e descritivas têm um importante papel na organização textual, estabelecemos como objetivo geral verificar a organização dos planos de texto e a função das sequências narrativas e descritivas nos contos de João Antônio e como objetivos específicos identificar, descrever, analisar e discutir os planos de texto e as sequências textuais narrativas e descritivas. De modo a desenvolvermos este estudo, buscamos os fundamentos teóricos oferecidos pela Linguística Textual, mais especificamente pela Análise Textual dos Discursos (ADAM, 2011; MARCUSCHI, 2005; 2008; 2013 KOCH, 2011; 2013; 2014; MARQUESI, 2004). Para tratarmos de tipo e gênero, respaldamo-nos no aporte teórico de Travaglia (2004; 2007; 2009; 2014), Bakhtin (2011[1979]) e Marcuschi (2005); de modo a conceituarmos plano de texto e sequência textual, fundamentamo-nos em Adam (2011) e em Cabral (2013); quanto à sequência textual narrativa, buscamos os estudos de Adam (2011) e para conceituarmos tipo descritivo e sequências textuais descritivas, valemo-nos das pesquisas desenvolvidas por Marquesi (2004; 2012) e Adam (2011). De início, analisamos sete contos de João Antônio publicados na revista Realidade entre 1967 e 1968. Posteriormente, para compor o corpus desta pesquisa, optamos por apresentar a análise de dois contos, a título de exemplificação. Os resultados obtidos evidenciam que tanto as sequências descritivas quanto as sequências narrativas, além de concorrerem para o estabelecimento do plano de texto, contribuem para conferir ao universo ficcional descrito por João Antônio um peculiar senso de realidade, o que marca a confluência entre literatura e jornalismo que caracteriza os textos do autor publicados na citada revista

L'étude comparative de l'architecture des génomes mammaliens a révélé l'association des séquences répétées et des réarrangements. Cette thèse porte sur la dynamique et le rôle dans les remaniements de deux types de séquences répétées: les clusters ribosomiques et les satellites. Ces séquences sont analysées par une approche cytogénomique (FISH, CO-FISH) dans le genre Mus connu pour sa diversité chromosomique, et pour lequel les phylogénies moléculaires et chromosomiques sont disponibles.1) La distribution chromosomique des clusters ribosomiques, établie chez 19 espèces, a permis de reconstruire les états ancestraux des clusters. Cette analyse montre que les clusters (24%) sont associés à des points de cassures, mais présentent également une grande labilité en l'absence de réarrangements. De plus, une forte association entre les clusters et les centromères est mise en évidence. 2) Le sous-genre Mus se caractérise par un caryotype très conservé excepté chez une sous-espèce de la souris domestique (M. musculus domesticus), qui est connue pour son extraordinaire radiation chromosomique impliquant les séquences satellites du centromère. Afin de rechercher les spécificités génomiques responsables de ce patron d'évolution contrasté, la dynamique évolutive des séquences satellites a été analysée chez 11 taxons. Révélant des différences qualitatives entre taxons, cette étude a permis de proposer un scénario évolutif de ces séquences. Toutefois, aucune des caractéristiques étudiées (composition, orientation) n'est propre à M. m. domesticus, et ne permet de rendre compte de sa plasticité chromosomique. De même, chez cette dernière, aucun lien entre la quantité de séquences satellites et la fréquence d'implication des chromosomes dans les réarrangements n'est mis en évidence.Cette étude confirme que les séquences répétées participent à l'évolution chromosomique, mais ne constituent pas à elles seules l'élément clef de cette dernière. / Comparative analyses of the architecture of mammalian genomes have highlighted the association between repetitive sequences and rearrangements. This thesis focuses on the evolutionary dynamics of two repeat sequences (ribosomal clusters and satellites) and explores their role in chromosomal change. These sequences are analyzed by a cytogenomic approach (FISH, CO-FISH) in the genus Mus that is known for its chromosomal diversity and for which molecular and chromosomal phylogenies are available.1) The chromosomal distribution of ribosomal clusters, established in 19 species, allowed us to reconstruct the ancestral states of clusters. This analysis demonstrated that 24% of clusters were associated with breakpoints, whereas others showed high lability in the absence of rearrangements. Moreover, a strong association between clusters and centromeres was retrieved.2) The subgenus Mus is characterized by a highly conserved karyotype except for one subspecies of the house mouse (M. musculus domesticus), that displays an extraordinary chromosomal radiation involving centromeric satellite sequences. To determine the genomic traits related to this difference in rate, the evolutionary dynamics of satellite sequences was analyzed in 11 taxa. From the qualitative differences evidenced between taxa, an evolutionary scenario of these sequences is proposed. None of the studied features (composition, orientation) of these sequences was found to be specific to M. m. domesticus, and could explain its chromosomal plasticity. Similarly, in the latter, no relationship between satellite sequence quantity and the rearrangement frequency of chromosomes was found.This study confirms that although repeated sequences are involved in chromosomal evolution, they aren't in themselves the key element of the latter.
