Full textAbstract:
Huge amount of data flows around the Internet every second, but for the data to be
useful at its destination, it must be presented in a way such that the target has little problem interpreting it. Current data exchange technologies may rearrange the
structure of data to suit expectations at the target. However, there may be semantics
behind data (e.g. knowing the title of a book can determine its #pages) that may
be violated after data translation. These semantics are expressed as integrity constraints (IC) in a database. Currently, there is no guarantee that the exchanged data
conforms to the target’s ICs. As a result, existing applications (e.g. user queries)
that assume such semantics will no longer function correctly. Current constraint
repair techniques deal with data after it has been translated; thus take no consideration of the integrity constraints at the source. Moreover, such constraint repair
methods usually involve addition/deletion/modification of data, which may yield
incomplete or false data. We consider the constraints of both source and target
schemas; together with the mapping, we can efficiently detect which constraint is
violated and suggest ways to correct the mappings.

Full textAbstract:
The World Wide Web is a rich source of information and continues to expand in size and complexity. Mainly because the data on the web is lack of rigid and uniform data models or schemas, how to effectively and efficiently manage web data and retrieve information is becoming a challenge problem. Discovering web page communities, which capture the features of the web and web-based data to find intrinsic relationships among the data, is one of the effective ways to solve this problem. A web page community is a set of web pages that has its own logical and semantic structures. In this work, we concentrate on the web data in web page format and exploit hyperlink information to discover (construct) web page communities. Three main web page communities are studied in this work: the first one is consisted of hub and authority pages, the second one is composed of relevant web pages with respect to a given page (URL), and the last one is the community with hierarchical cluster structures. For analysing hyperlinks, we establish a mathematical framework, especially the matrix-based framework, to model hyperlinks. Within this mathematical framework, hyperlink analysis is placed on a solid mathematic base and the results are reliable. For the web page community that is consisted of hub and authority pages, we focus on eliminating noise pages from the concerned page source to obtain another good quality page source, and in turn improve the quality of web page communities. We propose an innovative noise page elimination algorithm based on the hyperlink matrix model and mathematic operations, especially the singular value decomposition (SVD) of matrix. The proposed algorithm exploits hyperlink information among the web pages, reveals page relationships at a deeper level, and numerically defines thresholds for noise page elimination. The experiment results show the effectiveness and feasibility of the algorithm. This algorithm could also be used solely for web-based data management systems to filter unnecessary web pages and reduce the management cost. In order to construct a web page community that is consisted of relevant pages with respect to a given page (URL), we propose two hyperlink based relevant page finding algorithms. The first algorithm comes from the extended co-citation analysis of web pages. It is intuitive and easy to be implemented. The second one takes advantage of linear algebra theories to reveal deeper relationships among the web pages and identify relevant pages more precisely and effectively. The corresponding page source construction for these two algorithms can prevent the results from being affected by malicious hyperlinks on the web. The experiment results show the feasibility and effectiveness of the algorithms. The research results could be used to enhance web search by caching the relevant pages for certain searched pages. For the purpose of clustering web pages to construct a community with its hierarchical cluster structures, we propose an innovative web page similarity measurement that incorporates hyperlink transitivity and page importance (weight).Based on this similarity measurement, two types of hierarchical web page clustering algorithms are proposed. The first one is the improvement of the conventional K-mean algorithms. It is effective in improving page clustering, but is sensitive to the predefined similarity thresholds for clustering. Another type is the matrix-based hierarchical algorithm. Two algorithms of this type are proposed in this work. One takes cluster-overlapping into consideration, another one does not. The matrix-based algorithms do not require predefined similarity thresholds for clustering, are independent of the order in which the pages are presented, and produce stable clustering results. The matrix-based algorithms exploit intrinsic relationships among web pages within a uniform matrix framework, avoid much influence of human interference in the clustering procedure, and are easy to be implemented for applications. The experiments show the effectiveness of the new similarity measurement and the proposed algorithms in web page clustering improvement. For applying above mathematical algorithms better in practice, we generalize the web page discovering as a special case of information retrieval and present a visualization system prototype, as well as technical details on visualization algorithm design, to support information retrieval based on linear algebra. The visualization algorithms could be smoothly applied to web applications. XML is a new standard for data representation and exchange on the Internet. In order to extend our research to cover this important web data, we propose an object representation model (ORM) for XML data. A set of transformation rules and algorithms are established to transform XML data (DTD and XML documents with DTD or without DTD) into this model. This model capsulizes elements of XML data and data manipulation methods. DTD-Tree is also defined to describe the logical structure of DTD. It also can be used as an application program interface (API) for processing DTD, such as transforming a DTD document into the ORM. With this data model, semantic meanings of the tags (elements) in XML data can be used for further research in XML data management and information retrieval, such as community construction for XML data.

Full textAbstract:
Undersökningen behandlar problem som tidigare forskning har uppmärksammat kring användandet av standarden XMI. XMI är avsedd för utbyte av modeller mellan modelleringsverktyg. Problem som uppmärksammats i användningen av XMI är att information om modeller inte alltid utbyts korrekt mellan verktyg. Detta kan resultera i att viktig information om modellerna går förlorad.
Undersökningen har till syfte att undersöka huruvida det är möjligt att extrahera data från modeller sparade i XMI-format utan tillgång till DTD eller XML-schema. En sådan möjlighet skulle kunna användas för att rädda information om modeller som annars skulle gå förlorad.
Den metod som har används för undersökningen är litteraturstudie, experiment och implementation samt hypotesprövning. Studien har resulterat i en implementation som är avsedd för att extrahera och presentera information från XMI-dokument.
Den slutsats som dras från undersökningen är att det går att extrahera data från modeller sparade i XMI-dokument förutsatt att sättet på vilken XMI-standarden har tillämpats är känt sedan tidigare.

Full textAbstract:
Mitosis is the process by which new cells are formed. Following accurate duplication of chromosomes, a cell must segregate its chromosomes into separate daughter cells with great accuracy. Failure to do so can result in genomic instability. Thus, entry into mitosis is tightly regulated via complex protein interactions. Microtubules (MTs) are versatile Tubulin polymers that constitute a considerable portion of the cytoskeleton, and it is the dramatic rearrangement of MTs upon mitotic entry that is required to build the mitotic spindle – the structure responsible for segregating the duplicated sister chromatids. MTs are modulated by MT-Associated Proteins (MAPs) that enact major MT rearrangements during mitosis. Identifying and understanding the role of MAPs is essential to the study of MT behaviour during mitosis. Recently, an RNAi screen for Drosophila MAPs identified two proteins that are the subject of this thesis; Msd1 and dTD-60. This thesis demonstrates that Msd1 is a novel MAP that is a component of the recently identified Augmin complex – the action of which is to generate a novel and redundant population of MTs within the mitotic spindle from existing MTs. Experiments described below demonstrate that Msd1 is required for Augmin-directed MT generation, and further investigate the role of this novel population of MTs within the developing fruit fly. Furthermore, a role for Msd1 in central spindle formation during anaphase in Drosophila is identified. dTD-60, the Drosophila homologue of human TD-60 (hTD-60), is the subject of another study described in this thesis. While hTD-60 has a role in metaphase progression through interaction with the Chromosomal Passenger Complex, a contrasting role for dTD-60 is investigated here. This thesis describes both a divergent localisation and phenotype of dTD-60, and further investigates the role of dTD-60 and its interactors in mitotic spindle formation.

L’objectif de cette thèse est d’obtenir des algorithmes sous linéaire permettant de répondre à des problèmes de décision dans les bases de données XML. Plus précisément, on s’inspire du property testing, pour décider approximativement si un arbre d’arité non bornée est valide par rapport à une DTD ; ou plus généralement si un tel arbre est reconnu par un automate d’arbre.Nous avons d’abord étudié le cas simple des mots, c’est-à-dire l’appartenance approchée d’un mot à un langage régulier défini par un automate non-déterministe. Sous la distance d’édition entres les mots, nous proposons un algorithme (ou tester) résolvant l’appartenance approchée en un temps polynomial : en la taille de l’automate aussi bien qu’en la précision (où le paramètre d’erreur). Nous avons aussi amélioré le précédent algorithme d’Alon, Krivelevich, Newman, et Szegedy, (2000) pour l’approximation de l’appartenance à un langage régulier modulo la distance de Hamming. Notre amélioration consiste à rendre cet algorithme polynomial en la taille de l’automate non-déterministe. Ensuite nous avons considéré l’appartenance approchée d’un arbre à un automate d’arbre sous la distance d’édition standard. Notre algorithme résout ce problème avec une complexité en temps exponentielle en la hauteur de l’arbre. Enfin nous avons considéré la validation approchée de DTD par rapport à la « strong edit distance » ; et nous obtenons dans ce cas un algorithme polynomial en la hauteur de l’arbre. Nous complétons nos résultats en prouvant une borne inférieure linéaire en la taille de l’arbre, pour la complexité de tout algorithme décidant l’appartenance approchée d’un arbre à une DTD, sous la strong edit distanceInspired by property testing, our objective is to obtain sublinear algorithms for deciding properties of XML databases approximatively. More precisely, we investigate the properties of whether an unranked tree is valid for a DTD, or more generally, whether it is recognized by a tree automaton. We start our studies by the simpler case of words and we considered the approximate membership problem for word non-deterministic automata. For this problem, we provide an efficient tester that runs in polynomial time in the size of the input automata and the error precision. We also improve the previous [Alon, Krivelevich, Newman, and Szegedy, 2000b] approximate membership tester for regular languages modulo the Hamming distance, so that it runs in polynomial time in the size of the input automata. Secondly, we study approximate membership testing for tree automata modulo the standard edit distance, and obtain a tester with run time exponential in the input tree depth. Next we consider approximate DTD validity modulo the strong edit distance. We then provide a tester that depends polynomially on the height of the tree. Finally, modulo the strong edit distance, we prove a linear lower bound on the depth of the input tree

Les techniques de pré-distorsion numérique (DPD) en bande de base permettant de linéariser un amplificateur de puissance (PA) avec effets mémoires non linéaires sont étudiées. Des éléments de base liés à la linéarisation du PA sont introduits, tels que le comportement non-linéaire du PA, son influence sur les systèmes de communication, sa modélisation et caractérisation. . . Puis certaines techniques de linéarisation existantes sont décrites, telles que le recul de puissance, le feedforward, la boucle de retour, l’amplification linéaire avec des composants non linéaires et la DPD. La DPD est la technique de linéarisation la plus prometteuse. L’architecture d’implémentation et les algorithmes d’identification de la DPD sont décrits. Dans cette thèse, quatre méthodes originales de DPD sont proposées. La première méthode (MP/LUT DPD) combine un modèle polynomial à mémoire (MP) avec une simple LUT. L’amplitude et la phase du signal prédistordu sont calculées par cette LUT. La deuxième méthode consiste à ajouter une interpolation linéaire à cette méthode. La troisième méthode consiste à améliorer la technique d’interpolation par une interpolation quadratique. La quatrième méthode exploite conjointement la MP DPD et un réseau de neurones. L’innovation principale dans cette dernière, réside dans l’apprentissage du réseau de neurones avec les échantillons du signal pré-distordu par la MP DPD. Enfin, les résultats de simulation et expérimentaux en termes de linéarisation, d’amélioration spectrale, de rotation de constellation et de temps de calculs sont fournis. Les méthodes proposées permettent différents compromis entre les performances de linéarisation et la complexitéBaseband digital predistortion (DPD) techniques for linearizing power amplifiers (PA) with memory effects are investigated in this thesis. Firstly, the relevant elements concerning PA linearization are introduced, such as PA nonlinearity behavior, its influence on the communication systems, its modeling and characterization. . . Then some existing linearization techniques are presented, such as power backoff, feedforward, feedback, linear amplification with nonlinear components and DPD. DPD is the most promising linearization technique. After that, the implementation architecture and identification algorithms of DPD are described. In this thesis, four DPD methods are proposed. The first method (MP/LUT DPD) is to combine a memory polynomial (MP) model and a simple non-interpolated LUT. Both the amplitude and phase of the predistorted signal are calculated by LUT. The second method is to add linear interpolation technique to MP/LUT DPD. The third method improves the second one by using a quadratic interpolation technique to MP/LUT DPD. The fourth method is to combine MP DPD and feed forward neural network. The principal innovation is that the training samples of the neural networks are the predistorded signal obtained by MP DPD. Finally, simulation results and experimental results are given and analyzed. The proposed methods provide different trade-off between the linearization performance, time efficiency and complexity

Full textAbstract:
Le développement d'Internet a subi une croissance assez rapide dans les cinq dernières années. Les documents accessibles sont publiés sous forme de pages HTML. Ce format de publication électronique ne sépare pas le contenu du document de sa forme. Le méta langage extensible XML définit un format bien structuré et répond aux exigences des nouvelles technologies, comme la présentation et la gestion des documents Web. XML est devenu une norme et il présente une technologie prometteuse pour la communication et la gestion de l'information. La communauté de l'Internet représentée par le consortium W3C a proposé en 1999 le langage des feuilles de styles extensible XSL. Ce langage est composé de deux parties: le langage XSL-FO pour le formatage des documents en vue de leurs présentations, et le langage XSLT pour la transformation des documents XML. Nous nous intéressons dans cette thèse à la partie transformation du langage XSL. XSLT est un langage plus simple qu'un langage de programmation classique. Il est en lui-même un langage très puissant et accessible au non programmeur. Cependant, il est difficile d'implémenter des règles de transformation complexes en XSLT, et la maintenance du code n'est pas évidente, surtout quand il s'agit d'une longue feuille de style qui manipule des transformations avancées. Comme alternative, nous proposons dans cette thèse un système de spécification des transformations de données structurées appelé TransM. Plusieurs approches de transformation de données structurées sont abordées. Nous présentons leurs avantages et leurs inconvénients ainsi que les plates-formes associées. Un problème que rencontrent les approches actuelles est la difficulté voire l'impossibilité de spécifier une transformation si les structures des documents source et cible sont complètement différentes. Un autre problème se manifeste par leur inaptitude à gérer des transformations sur des documents de structure récursive. Nous avons résolu ces problèmes à l'aide des règles de transformation de TransM. Un domaine d'application connexe bien qu'usuellement séparé dans la littérature est celui de la transformation de modèles. Les problèmes de la récursivité des éléments et de la différence structurelle sont affrontés aussi par les approches de transformation concernées. Pour résoudre ces problème de transformation, il suffit de représenter les modèles dans le format XMI, qui est une représentation XML des modèles, puis d'appliquer les transformations exprimées en TransM sur le document correspondant au format XML. TransM est basé sur un ensemble de règles dont nous définissons la grammaire. Les règles de spécification utilisées sont simples, intuitives et peuvent effectuer non seulement les transformations simples et directes, mais aussi des transformations de structure, point qui n'est pas toujours abordé dans les langages actuellement proposés. Les règles sont définies sur la grammaire des documents. Cette thèse étudie le problème de la transformation de données structurées. Afin de profiter des outils implantant le langage XSLT, le système génère du code XSLT pour accomplir la transformation au niveau des instances. Pour valider notre travail, nous avons développé un prototype de TransM, qui effectue avec succès les transformations avancées vouluesThe Internet has presented an increasing development during the last five years. The accessible documents are published under the HTML format. This type of publication does not separate the structure of the document from its content. The extensible meta-language XML has defined a well structured format that responds to the new technologies requirements, like the management and the presentation of Web documents. XML has became an international norm and it presents a promised technology for managing and communicating informations. The Internet community represented by the W3C consortium has proposed in 1999 a new extensible stylesheet language XSL. This language has two parts: the language XSL-FO to formatting documents against their presentation and the second part consists of the XSLT language that has been built for XML document transformations. We are interesting in this thesis by the transformation part of the XSL language XSLT is a transformation language that is more simple than classical programming languages. It has considerable computation power. .

"Le sujet présenté s'inscrit dans la thématique intitulée "Composants et Services de Collaboration". A l'intérieur de cette thématique générale, le travail de thèse consiste en l'étude et la conception de services de gestion de sessions pour la collaboration synchrone en co-présence distribuée. Cette étude commence d'abord par un état de l'art complet des systèmes et environnements de gestion de session, réalisé dans le cadre du projet européen "Distributed Systems Engineering (DSE)". Suite aux lacunes des systèmes de gestion de session analysés, il a été proposé un modèle basé sur un découpage utilisateurs/données/outils, qui permet de représenter et de mettre en œuvre des schémas de coordination de groupe plus riches et plus étendus, pour la gestion de session. La base théorique de ce modèle s'appuie sur des graphes étiquetés dynamiques, dont l'instance courante donne l'état instantané (ou vue courante) d'une instanciation de session, ces transformations étant liées à l'évolution et aux actions produites lors du déroulement de la session d'utilisateurs. L'architecture qui implante le modèle de coordination proposé s'appuie sur une approche en couches dont la principale originalité est de maintenir une indépendance entre la couche de coordination et son domaine d'utilisation, ici la gestion de session. Elle propose donc un médium de coordination qui fournit un service de graphes étiquetés générique. Le prototype de cette architecture, implanté, s'appuie sur les extensions collaboratives du langage JAVA, et sur les possibilités du langage XML en terme de structuration de données. Le domaine d'application concerne la réalisation d'une revue de projet pour la télé conception collaborative, revue liée à un scénario du projet européen DSE. "

L'approche est implantée par un algorithme appelé GREC.
Cet algorithme utilise l'automate d'arbre A qui accepte le langage défini par le schéma pour trouver les informations nécessaires à la modification.
Plus précisément, il utilise les expressions régulières des règles de transitions de A pour proposer les candidats.
Ainsi, les modifications sont faites sur les graphes qui représentent les automates d'états finis construits à partir des expressions régulières concernées.
Les expressions régulières engendrées par GREC représentent des schémas présentés à l'utilisateur afin qu'il choisisse le plus adapté à la sémantique de son application.

Nos travaux s'inscrivent dans le cadre de la recherche d'information sur documents semi-structurésde type XML. La recherche d'information structurée (RIS) a pour objectif de retourner des granules documentaires précis répondant aux besoins d'information exprimés par l'utilisateur au travers de requêtes. Ces requêtes permettent de spécifier, en plus des conditions de contenu, des contraintes structurelles sur la localisation de l'information recherchée. L'objectif de nos travaux est d'étudier l'apport de la structure des documents dans le processus d'appariement documents-requêtes. Puisque les contraintes structurelles des requêtes peuvent être représentées sous la forme d'un arbre et que, parallèlement, la structure du document, de nature hiérarchique, peut elle-même utiliser le même type de représentation, nous avons proposé plusieurs modèles de mesure de la similarité entre ces deux structures. La mesure de la similarité entre deux structures arborescentes ayant été étudiée par le domaine de la théorie des graphes, nous avons tout d'abord cherché à adapter les algorithmes de ce domaine à notre problématique. Suite à une étude approfondie de ces algorithmes au regard de la RIS, notre choix s'est porté sur la distance d'édition entre arbres (Tree Edit Distance - TED). Cet algorithme permet, au travers de l'application récursive de séquences de suppression et de substitution, de mesurer le degré d'isomorphisme (le degré de similarité) entre deux arbres. Constatant que ces algorithmes sont coûteux en mémoire et en calcul, nous avons cherché à en réduire la complexité et le temps d'exécution au travers d'approches de résumé et de la mise en place d'un algorithme de TED au coût de complexité plus bas. Etant donné que la TED est normalement utilisée avec des coûts d'opération fixes peut adaptés à notre problématique, nous en avons également proposé de nouveaux basés sur la distance dans le graphe formé par la grammaire des documents : la DTD. Notre deuxième proposition se base sur les Modèles de Langue. En recherche d'information, ces derniers sont utilisés afin de mesurer la pertinence au travers de la probabilité qu'un terme de la requête soit généré par un document. Nous avons utilisés les Modèles de Langue pour mesurer, non pas la probabilité de pertinence du contenu, mais celle de la structure. Afin de former un vocabulaire document et requête à même d'être utilisé par notre modèle de langue structurel nous avons utilisé une technique de relaxation pondérée (la relaxation est le relâchement des contraintes). Nous avons également proposé une méthode pour apparier le contenu des documents et celui des requêtes. L'appariement seul des structures étant insuffisant dans une problématique de recherche d'information : la pertinence d'un granule documentaire est jugée en priorité sur la pertinence de l'information textuelle qu'il contient. De ce fait, nous avons proposé une approche de mesure de la pertinence de ce contenu. Notre méthode utilise la structure de l'arbre afin d'opérer une propagation de la pertinence du texte en prenant en compte l'environnement des éléments traversés ainsi que le contexte global du document. Nos différents modèles ont été expérimentés sur deux tâches de la campagne d'évaluation de référence de notre domaine : Initiative for XML Retrieval. Cette campagne a pour but de permettre l'évaluation de systèmes de recherche d'information XML dans un cadre normalisée et comporte plusieurs tâches fournissant des corpus, des mesures d'évaluation, des requêtes, et des jugements de pertinence. Nous avons à ce propos participé à cette campagne en 2011. Pour nos expérimentations, les tâches que nous avons choisi d'utiliser sont : * La tâche SSCAS d'INEX 2005 qui utilise une collection d'articles scientifiques d'IEEE. Cette collection est orientée texte dans la mesure où la structure exprimée dans les documents qu'elle contient est similaire à celle d'un livre (paragraphe, sections). * La tâche Datacentric d'INEX 2010 dont la collection est extraite d'IMDB. Cette collection est orientée données dans la mesure où les termes des documents sont très spécifiques et peu redondants et que la structure est porteuse de sens. Nos différentes expérimentations nous ont permis de montrer que le choix de la méthode d'appariement dépend de la collection considérée. Dans le cadre d'une collection orienté texte, la structure peut être prise en compte de manière non stricte et plusieurs sous-arbres extraits du document peuvent être utilisés simultanément pour évaluer la similarité structurelle. Inversement, dans le cadre d'une collection orientée donnée, la prise en compte stricte de la structure est nécessaire. Etant donné que les éléments recherchés portent une sémantique, il est alors important de détecter quelle partie du document est à priori pertinente. La structure à apparier doit être la plus précise et minimale possible. Enfin, nos approches de mesures de la similarité structurelle se sont montrées performantes et ont amélioré la pertinence des résultats retournés par rapport à l'état de l'art, à partir du moment où la nature de la collection a été prise en compte dans la sélection des arbres structurels en entréeThe work presented in this PhD thesis concerns structured information retrieval and focuses on XML documents. Structured information retrieval (SIR) aims at returning to users document parts (instead of whole documents) relevant to their needs. Those needs are expressed by queries that can contain content conditions as well as structural constraints which are used to specify the location of the needed information. In this work, we are interested in the use of document structure in the retrieval process. We propose some approaches to evaluate the document-query structural similarity. Both query structural constraints and document structures can be represented as trees. Based on this observation we propose two models which aim at matching these tree structures. As tree matching is historically linked with graph theory, our first proposition is based on an adaptation of a solution from the graph theory. After conducting an in depth study of the existing graph theory algorithms, we choose to use Tree Edit Distance (TED), which measures isomorphism (tree similarity) as the minimal set of remove and replace operations to turn one tree to another. As the main drawback of TED algorithms is their time and space complexity, which impacts the overall matching runtime, we propose two ways to overcome these issues. First we propose a TED algorithm having a minimal space complexity overall. Secondly, as runtime is dependent on the input tree cardinality (size) we propose several summarization techniques. Finally, since TED is usually used to assess relatively similar trees and as TED efficiency strongly relies on its costs, we propose a novel way, based on the DTD of documents, to compute these costs. Our second proposition is based on language models which are considered as very effective IR models. Traditionally, they are use to assess the content similarity through the probability of a document model (build upon document terms) to generate the query. We take a different approach based purely on structure and consider the document and query vocabulary as a set of transitions between document structure labels. To build these vocabularies, we propose to extract and weight all the structural relationships through a relaxation process. Finally, as relevance of the returned search results is first assessed based on the content, we propose a content evaluation process which uses the document tree structure to propagate relevance: the relevance of a node is evaluated thanks to its leaves as well as with the document context and neighbour nodes content relevance. In order to validate our models we conduct some experiments on two data-sets from the reference evaluation campaign of our domain: Initiative for XML retrieval (INEX). INEX tracks provide documents collections, metrics and relevance judgments which can be used to assess and compare SIR models. The tracks we use are: * The INEX 2005 SSCAS track whose associated documents are scientific papers extracted from IEEE. We consider this collection to be text-oriented as the structure used is similar to the one we can find in a book. * The INEX 2010 Datacentric track which uses a set of documents extracted from the Internet Movie Database (IMDB) website. This collection is data-oriented as document terms are very specific while the structure carries semantic meaning. Our various experiments show that the matching strategy strongly relies on the document structure type. In text-oriented collections, the structure can be considered as non-strict and several subtrees can be simultaneously used to assess the relevance. On the opposite, structure from documents regarded as data-centered should be used as strictly as possible. The reason is that as elements labels carry semantic, documents structures contain relevant and useful information that the content does not necessarily provide. Finally, our structural similarity approaches improve relevance of the returned results compared to state-of-the-art approaches, as long as the collection nature is considered when extracting the input trees for the structural matching process

Estudos termoanalíticos de alguns aditivos alimentares da classe dos realçadores de sabor foram desenvolvidos visando avaliar sua estabilidade e resistência durante o preparo de alimentos a quente assim como investigar os eventuais intermediários de decomposição que poderiam resultar destes processos. Os sais foram obtidos de fontes industriais ou sintetizados e submetidos à caracterização por análise elementar, espectrometria vibracional na região do infra-vermelho, termogravimetria/termogravimetria derivada, análise térmica diferencial e em alguns casos, calorimetria exploratória diferencial. Foram estudados o ácido glutâmico e seus sais de amônio, lítio e sódio mono e dissubstituídos. Em todos os casos observou-se uma conversão a piroglutamato após desidratação dos sais monossubstituídos, a qual ocorre via a a-carboxila. A estabilidade térmica destes sais foi da ordem de 190-200 °C. No caso dos sais dissubstituídos de lítio e sódio não houve conversão ao piroglutamato pois as duas carboxilas estão salificadas. Os glutamatos de magnésio, cálcio estrôncio e bário, também foram preparados e investigados quanto ao seu comportamento térmico. Os sais se formaram na estequiometria 2:1 (ligante:metal), apresentando águas de hidratação em número característico e foram estáveis até 190- 200 °C. Finalmente foram estudados os mecanismos de decomposição térmica do inosinato-monofosfato de sódio e do guanilato-monofosfato de sódio, dois nucleotídeos que apresentam a propriedade de realçar o sabor de alimentos. Ambos apresentaram elevado grau de hidratação, para o qual foi possível distinguir mecanismos característicos de desidratação. A decomposição dos sais anidros ocorreu com saída do grupo purínico, seguida da decomposição do restante da molécula e formação de pirofosfato de sódio como resíduo final.Thermal analytical studies of some food addictives of the flavor enhancer class were developed in order to evaluate their stability and resistance to the hot cooking process, as well as to identify the intermediaries of thermal decomposition that could remain at the end of such processes. The salts were obtained from industrial sources or synthesized and characterized by elemental analysis, infra-red spectroscopy, thermogravimetry/derivative thermogravimetry, differential thermal analysis and in some opportunities to differential scanning calorimetry. The glutamic acid and its ammonium, lithium and sodium salts mono and disubstituted were investigated. In all cases a conversion to pyroglutamate has been observed in the free acid and its monosubstituted salts after dehydration. The conversion undergoes by the ?-carboxyl group. The thermal stability was observed to be as high as 190-200 °C. In the case of the lithiu m and sodium dissubstituted salts any conversions to pyroglutamates were observed, once both carboxyl groups were salified. Magnesium, calcium, strontium and barium glutamates has also been synthesized and investigated in relation to its thermal behavior. The salts were formed in the 2:1 stoichiometry (ligand:metal), presenting hydration waters in a characteristic content and showed to be stable up to 190-200 °C. Finally the thermal decomposition mechanisms of dissodium inosinatemonophosphate and dissodium guanilate-monophosphate two nucleotides with flavor enhancement properties in food were also investigated. Both presented high degree of hydration, to which it was possible to propose a water release mechanism. The decomposition of the anhydrous salts occurred with release of the purine group followed by the decomposition of the rest of the molecule generating sodium pyrophosphate as residue.

The main sources of the pollution of the pesticides are fire of the warehouses of the pesticides and pesticides dumps. The negative impact on environment of pesticides is irreversible, causing various degenerations, aberrations and diseases to animals and plants. It was estimated that in Marijampolio and Tryškių pesticides dumps, concentration of some pesticides exceeds HN 60:2004 stated MCL (maximum concentration levels) values from 1 to 1460 times in Marijampolio pesticide dump while in Tryškių pesticides dump from 1,5 to 3600 times. Whereas the same concentration in ground samples in 0,9 -1.0 depth declines and MCL exceed just from 1 to 38 times in Marijampolio pesticides dumps, and to 144 times in Tryškių pesticides dumps. In Tryškių and Marijampolio pesticides dumps soil and ground analyses were made. It was estimted that ground water in Tryškių pesticide dump area is polluted deeply by pesticides. Its pollution of separate pesticides by different normative act stated MCL exeeds to 96 times in Tryškių and to 1000 times in Marijampolio pesticides dumps areas.

Full textAbstract:
In vitro testing includes both cell-based and cell-free systems that can be used to detect toxicity induced by xenobiotics. In vitro methods are especially useful in rapidly gathering intelligence regarding the toxicity of compounds for which none is available such as new chemical entities developed in the pharmaceutical industry. In addition to this, in vitro investigations are invaluable in providing information concerning mechanisms of toxicity of xenobiotics. This type of toxicity testing has gained popularity among the research and development community because of a number of advantages such as scalability to high throughput screening, cost-effectiveness and predictive power. Hepatotoxicity is one of the major causes of drug attrition and the high cost associated with drug development poses a heavy burden on the development of new chemical entities. Early detection of hepatotoxic agents by in vitro methods will improve lead optimisation and decrease the cost of drug development and reduce drug-induced liver injury. Literature highlights the need for a cellbased in vitro model that is capable of assessing multiple toxicity parameters, which assesses a wider scope of toxicity and would be able to detect subtle types of hepatotoxicity. The present study was aimed at developing an in vitro procedure capable of mechanistically profiling the effects of known hepatotoxin dichlorodiphenyl trichloroethane (DDT) and its metabolites, dichlorodiphenyl dichloroethylene (DDE) and dichlorodiphenyl dichloroethane (DDD) on an established liver-derived cell line, HepG2, by evaluating several different aspects of cellular function using a number of simultaneous in vitro assays on a single 96 well microplate. Examined parameters have been suggested by the European Medicines Agency and include: cell viability, phase I metabolism, oxidative stress, mitochondrial toxicity and mode of cell death (apoptosis vs. necrosis). To further assess whether the developed method was capable of detecting hepatoprotection, the effect of the known hepatoprotectant, N-acetylcysteine, was determined. Viability decreased in a dose-dependent manner yielding IC50 values of 54 μM, 64 μM and 44 μM for DDT, DDE and DDD, respectively. Evaluation of phase I metabolism showed that cytochrome P4501A1 activity was dose-dependently induced. Test compounds decreasedlevels of reactive oxygen species, and significantly hyperpolarised the mitochondrialmembrane potential. Assessment of the mode of cell death revealed a significant elevation of caspase-3 activity, with DDD proving to be most potent. DDT alone induced dosedependent loss of membrane integrity. These results suggest that the tested compounds produce apoptotic death likely due to mitochondrial toxicity with subsequent caspase-3 activation and apoptotic cell death. The developed in vitro assay method reduces the time it would take to assess the tested parameters separately, produces results from multiple endpoints that broadens the scope of toxicity compared to single-endpoint methods. In addition to this the method provides results that are truly comparable as all of the assays utilise the same batch of cells and are conducted on the same plate under the exact same conditions, which eliminates a considerable amount of variability that would be unavoidable otherwise. The present study laid a solid foundation for further development of this method by highlighting the unforeseen shortcomings that can be adjusted to improve scalability and predictive power.Thesis (PhD)--University of Pretoria, 2011.

Idag väntar många patienter på transplantation av ett eller flera organ. Med nuvarande lagstiftning identifieras inte alla potentiella organdonatorer och därför kan inte dessa organ tas tillvara. Regeringen har därför tillsatt en utredning om det kan bli aktuellt med organdonation efter hjärtdöd. Detta uttrycks internationellt som Donation after Cardiac Death (DCD). Denna studiens syfte var att beskriva intensivvårdssjuksköterskors uppfattningar, tankar och känslor, samt förbereddhet kring begreppet donation efter hjärtdöd. Sju intervjuer av intensivvårdssjuksköterskor på två sjukhus i västra Sverige genomfördes och data analyserades med kvalitativ innehållsanalys. Resultatet presenteras som fyra kategorier: Upplevda farhågor och potentiella konsekvenser av DCD, Mötet med anhöriga, Tankar och känslor kring organisatoriska svårigheter och Tankar och känslor kring etiska dilemman. Slutsatser var att de intervjuade intensivvårdssjuksköterskorna ställde sig positiva till DCD och tidigare forskning visar att det kan vara en källa till ökning av organtillgång förutsatt att det är organisatoriskt genomförbart.Today there are many patients on the waiting list to receive one or more organ transplants. With the current Swedish legislation not all potential organ donors are identified and therefore these organs are omitted as potential transplants. The government is in the process of investigating the possibility to implement organ donation after cardiac death, i.e. DCD. The aim of the study was to describe ICU nurses’ understanding, thoughts and emotions, as well as their preparations regards to DCD. Seven ICU nurses at two hospitals in western Sweden were interviewed and data were processed through qualitative content analysis. The results are presented as four categories: Perceived fears and potential consequences regarding DCD, the meeting with relatives, Thoughts and emotions regarding organizational difficulties and Thoughts and emotions regarding ethical dilemmas. Conclusions derived from the findings in the interviews with ICU nurses were a fully positive perception of DCD and that DCD could mean an increase in the amount of available organ donors given that legalisation and organisation processes are clear and possible to carry out.

O comportamento térmico, a obtenção e caracterização de formas cristalinas do anti-histamínico loratadina foram investigado. A escolha do anti-histamínico loratadina como objeto de estudo resulta do seu interesse farmacológico. A loratadina é a Denominação Comum Internacional (DCI) dada ao etil 4-(8-cloro-5,6-dihidro-11H-benzo[5,6]cicloheptano[1,2-b]piridino-11-ilideno)-1-piperidinocarboxilato, que é um potente antialérgico e anti-histamínicos tricíclico, não-sedativo de ação prolongada. Formas cristalinas foram preparadas e estudadas com vista à identificação de formas polimórficas. Os solventes utilizados na preparação das soluções foram: álcool etílico, acetonitrila, álcool isopropílico, acetona, álcool metílico, éter isopropílico, éter metil terc-butílico, tolueno, clorofórmio. A cristalização foi realizada por evaporação do solvente em diferentes temperaturas. A calorimetria exploratória diferencial (DSC), termogravimetria e termogravimetria derivada (TG/DTG), análise térmica diferencial (DTA), difração de raios X (DRX) e a ressonância magnética nuclear (RMN) foram às técnicas utilizadas na caracterização das formas polimórficas. A maioria das amostras obtidas pelas técnicas de cristalização consistiam de misturas de formas cristalinas, contendo, por vezes, formas metaestáveis e formas amorfas. Identificaram-se duas formas cristalinas como polimorfos da loratadina, cujas curvas DSC mostrou interconversão entre ambas.The preparation, characterization and thermal behavior of the crystalline forms of the antihistamine loratadine has been developed.

Loratadine is the International Common Denomination (ICD) given to ethyl 4-(8-chloro-5,6-dihydro-11H-benzo [5,6] cyclohepta[1,2-b]pyridin-11-ylidene)-1-piperidinecarboxylate, a potent anti-allergic and anti-histamincs, tricyclic, non-sedating long acting. Crystalline forms were prepared and studied for the identification of polymorphic forms. The solvents used in preparing the solutions were: ethanol, acetonitrile, isopropyl alcohol, acetone, methyl alcohol, isopropyl ether, methyl tert-butyl ether, toluene, chloroform. The crystallization was performed by evaporating the solvent at different temperatures. The differential scanning calorimetry (DSC), thermogravimetry and derivative thermogravimetry (TG/DTG), differential thermal analysis (DTA), X-ray diffraction (XRD) and nuclear magnetic resonance (NMR) techniques were used to characterize the polymorphic forms. Most of the samples obtained by the crystallization were mixtures of crystalline forms, containing sometimes forms metastable and amorphous forms. It was identified as two crystalline polymorphic forms of loratadine, whose DSC curves demonstrated that they are interconvertable.

Previous issue date: 2013-03-22Bioidentical hormones are defined as compounds that have exactly the same chemical and molecular structure as hormones that are produced in the human body. It is believed that the use of hormones may be safer and more effective than the non-bioidentical hormones, because binding to receptors in the organism would be similar to the endogenous hormone. Bioidentical estrogens have been used in menopausal women, as an alternative to traditional hormone replacement therapy. Thermal data of these hormones are scarce in literature. Thermal analysis comprises a group of techniques that allows evaluating the physical-chemistry properties of a drug, while the drug is subjected to a controlled temperature programming. The thermal techniques are used in pharmaceutical studies for characterization of drugs, purity determination, polymorphism identification, compatibility and evaluation of stability. This study aims to characterize the bioidentical hormones estradiol and estriol through thermal techniques TG/DTG, DTA, DSC, DSC-photovisual. By the TG curves analysis was possible to calculated kinetic parameters for the samples. The kinetic data showed that there is good correlation in the different models used. For both estradiol and estriol, was found zero order reaction, which enabled the construction of the vapor pressure curves. Data from DTA and DSC curves of melting point and purity are the same of literature, showed relation with DSC-photovisual results. The analysis DTA curves showed the fusion event had the best linearity for both hormones. In the evaluation of possible degradation products, the analysis of the infrared shows no degradation products in the solid state

Bakgrund: Över hela världen råder det brist på organ. 1 januari 2019 stod 807 personer på väntelistan för att få ett nytt organ i Sverige. Efterfrågan på organ är större än tillgången. Efterfrågan skulle kunna tillmötesgå bättre om DCD (eng. Donation after Circulatory Death) kan implementeras som ett komplement till DBD (eng. Donation after Brain Death). Det har pågått ett pilotprojekt på sex olika sjukhus i Sverige.Måletmed projektet var att utreda om DCD i framtiden kan vara ett komplement till den idag etablerade donationsprocessen DBD vilket leder till att sjukvården kan möta allmänhetens donationsvilja samt öka antalet organ för transplantation. Då DCD inte är nationellt implementerat och genom att intensivvårdssjuksköterskor har ansvaret för att vårda potentiella organdonatorer är det viktigt med forskning som belyser intensivvårdssjuksköterskorsresonemang och föreställningar kring DCD.Syfte:Syftet var att beskriva intensivvårdssjuksköterskors resonemang och föreställningar om donation vid kontrollerad DCD.Metod:Kvalitativ intervjustudie med ändamålsenligt urval genomfördes. Data analyserades med kvalitativ innehållsanalys.Resultat:Analysen resulterade i fyra kategorier; Att påbörja något nytt inom området donation, Att erhålla kunskap minskar farhågor och oro, Att införa donation efter cirkulationsstillestånd ger möjlighet att möta en hög donationsvilja och att informera och ge tröst till anhöriga.Slutsats: Denna studie visar att engagemanget är stort hos intensivvårdssjuksköterskor och att tilltron tillett införande av DCD är hög. Genom att införa DCD som ett komplement till DBD så skulle fler donationer kunna genomföras och på sikt kunna matcha efterfrågan på organ. Mer forskning samt utbildning behövs för att öka kunskapen utifrån de krav som kommer att ställas på intensivvårdssjuksköterskor vid en eventuell implementering av DCD.

Full textAbstract:
O tipo de crescimento da haste da soja é característica diferenciadora de cultivares. Os genes, Dt1 e Dt2, afetam a terminação da haste, visto que os tipos de crescimento são classificados em determinado, semideterminado e indeterminado. O tipo de crescimento determinado predominou no Brasil até o início dos anos 2000, ao passo que, na contemporaneidade, há preferência pelo tipo de crescimento indeterminado, principalmente na região centro sul do Brasil. No entanto, a dificuldade de seleção e a tendência de se utilizar com maior frequência cultivares indeterminadas e semideterminadas, nos programas de melhoramento, têm provocado a caracterização fenotípica errônea dos genótipos. Nesse sentido, o presente trabalho teve como objetivos: (a) mapear e validar marcadores moleculares para classificar a soja quanto ao tipo de crescimento, buscando facilitar a descrição de cultivares e a seleção genotípica; (b) avaliar características agronômicas de progênies e suas linhas irmãs contrastantes para o gene Dt1 identificadas pelo fenótipo dos respectivos tipos de crescimento. Para mapeamento e validação dos marcadores moleculares, foram utilizadas duas populações F2:3: T 117 (tipo de crescimento semideterminado) x Igra RA 518 RR (tipo de crescimento indeterminado) e CD 235RR (tipo de crescimento determinado) x Igra RA 518 RR. O estudo evidenciou que a associação do marcador molecular ao gene GmTFL1b foi eficiente na classificação dos tipos de crescimento em soja. O marcador sat_064 está ligado ao gene Dt2, localizado no Grupo de Ligação G do mapa consenso da soja, com frequência de recombinação de 19,4%. Os marcadores moleculares para os genes Dt1 e Dt2 são eficientes na descrição de genótipos quanto ao tipo de crescimento da haste da soja bem como para serem utilizados na seleção em programa de melhoramento. Na avaliação das características de três progênies F4:6:9 de soja, cada uma com três linhas irmãs as quais contrastam para o gene Dt1, utilizando para diferenciação dos tipos de crescimento o fenótipo. Nas progênies avaliadas, não houve diferenças entre os tipos de crescimento indeterminado (Dt1Dt1) e determinado (dt1dt1) na massa de planta, diâmetro da haste e massa total de grãos. Quanto as linhas com tipo de crescimento semideterminado (Dt1dt1), apresentaram massa de planta, diâmetro da haste, número de vagens, número de ramos e massa total de grãos maiores que as linhas com tipo de crescimento indeterminado, e altura de plantas foram maiores que linhas com tipo de crescimento determinado. Além disso, comprimento do racemo da haste é maior nas plantas com tipo de crescimento determinado que em plantas com tipo de crescimento semideterminado. Entre as progênies avaliadas, as do tipo de crescimento determinado apresentam racemos apicais nos ramos nas plantas e as com tipos de crescimento semideterminado e indeterminado não apresentam racemos apicais nos ramos. Nessas linhagens avaliadas, havia um nível de homozigose de 98,4375%, a segregação foi basicamente para o gene Dt1 de modo a facilitar a classificação de tipos de crescimento.The type of stem growth of soybean is a distinguishing feature of cultivars. The genes Dt1 and Dt2 affect termination of the stem, and the types of growth are classified in determinate, semi-determinate and indeterminate. The predominant type of determinate growth in Brazil until the early 2000's. Nowadays preference for type of indeterminate growth is mainly in the central southern Brazil. The difficulty of a precise indication for the growth type in cultivars of soybean is offently present in breeding programs. Phenotypic characterization is sometimes erroneously described. This study aimed to: (a) map and validate molecular markers to classify the type of soybean growth, seeking to facilitate the description of cultivars and genotypic selection, (b) evaluate agronomic characteristics and their sisters contrasting progeny lines for sisters Dt1 gene identified by the phenotype of the respective types of growth. For mapping and validation of molecular markers were used two populations F2:3: T 117 (semi-determinate growth type) x Igra RA 518 RR (sort of indeterminate growth) and CD 235RR (determinate growth type) x Igra RA 518 RR. The study revealed that the association of the molecular marker to the gene GmTFL1b was efficient in the classification of types of growth in soybean. The marker sat_064 was connected to Dt2 gene which is located in the Liaison Group G of the consensus map of soybeans with recombination frequency of 19.4%.The Molecular markers for genes dt1 and dt2 were efficient in describing the genotypes for of soybean stem growth, as well as, for use in selection of a breeding program. The characteristics of three soybean progeny F4:6:9, each one with three sisters contrasting lines for gene Dt1, using for differentiation of phenotype growth type have been evaluated. Results indicated that there were no differences between indeterminate (Dt1Dt1) and determinate (dt1dt1) growth types when the mass of plant, stem diameter and total mass of grains. On the other side, semi-determinate growth type lines (Dt1dt1) has shown mass of plant, stem diameter, number of pods, number of branches and the total mass of grains larger than of indeterminate soybean growing type. The height of plants were greater on plants of semi determinate growth type. The length of the stem raceme was greater on determinate than plants of semi determinate growth type. The three evaluated progenies exhibited apical racemes on the branches of determinate with semi-determinate. Indeterminate growth types did not show apical racemes in the branches. These strains reached a level of homozygosis of 98.4375%. Segregation was basically for gene Dt1 which facilitated the classification in soybean of different growth type.

Previous issue date: 2014-03-24Since its synthesis over 48 years rifampicin has been extensively studied. The literature reports the characterization of thermal events for rifampicin in nitrogen atmosphere, however, no characterization in synthetic air atmosphere. This paper aims to contribute to the thermal study of rifampicin through thermal (TG / DTG, DTA, DSC and DSC - FOTOVISUAL ) and non-thermal (HPLC, XRPD , IR - FTIR , PCA) and its main degradation products ( rifampicin quinone , rifampicin N-oxide 3- formylrifamicin). Rifampicin study was characterized as polymorph form II from techniques DSC, IR and XRPD. TG curves for rifampicin in synthetic air atmosphere showed higher thermal stability than those in N2, when analyzed Ti and Ea. There was characterized as overlapping events melting and recrystallization under N2 with weight loss in the TG curve, suggesting concomitant decomposition. Images DSCFotovisual showed no fusion event and showed darkening of the sample during analysis. The DTA curve in synthetic air atmosphere was visually different from DTA and DSC curves under N2, suggesting the absence of recrystallization and melting or presence only decomposition. The IV - FTIR analysis along with PCA analysis and HPLC and thermal data suggest that rifampicin for their fusion is concomitant decomposition of the sample in N2 and fusion events and recrystallization do not occur in synthetic air atmosphere. Decomposition products studied in an air atmosphere showed no melting event and presented simultaneously to the decomposition initiation of heating after process loss of water and / or solvent, varying the Ti initiating events. The Coats - Redfern , Madsudhanan , Van Krevelen and Herwitz - Mertzger kinetic parameters for samples , through the methods of OZAWA , in an atmosphere of synthetic air and / or N2 rifampicin proved more stable than its degradation products . The kinetic data showed good correlation between the different models employed. In this way we contribute to obtaining information that may assist studies of pharmaceutical compatibility and stability of substances

Full textAbstract:
Background: Gliomas are neuroepithelial tumours classified by cell type and grade. In adults, low-grade gliomas are comprised mainly of astrocytomas and oligodendrogliomas grade II. The aim was to non-invasively characterise suspected low-grade gliomas through use of 11C-methionine-PET and physiological MRI in order to facilitate treatment decisions. Materials and methods: Patients with suspected low-grade glioma were prospectively and consecutively included after referral to the Neurosurgical Department, Uppsala University Hospital, between February 2010 and February 2014. All patients underwent morphological MRI, perfusion MRI, diffusion MRI and 11C-methionine PET. The institutional review board approved the study, and written informed consent was obtained prior to participation from each patient. Results: 11C-methionine PET hot spot regions corresponded spatially with regions of maximum relative cerebral blood volume in dynamic susceptibility contrast (DSC) perfusion MRI. The skewness of the transfer constantin dynamic contrast-enhanced (DCE) perfusion MRI, and the standard deviation of relative cerebral blood flow in DSC perfusion MRI could most efficiently discriminate between glioma grades II and III. In diffusion MRI, tumour fractional anisotropy differed between suspected low-grade gliomas of different neuropathological types. Quantitative diffusion tensor tractography was applicable for the evaluation of tract segment infiltration. Conclusion: PET and physiological MRI are able to characterise low-grade gliomas and are promising tools for guiding therapy and clinical decisions before neuropathological diagnosis has been obtained.

Dissertação de Mestrado Integrado em Medicina VeterináriaA doença articular degenerativa (DAD) apresenta uma etiologia multifatorial, envolvendo fatores genéticos, biomecânicos e bioquímicos, caracterizando-se pela existência de degeneração da cartilagem articular com produção de novo tecido ósseo. A sua prevalência na população felina parece aumentar com a idade, sendo o seu diagnóstico feito com base na associação de sinais clínicos e alterações ao exame radiográfico. O presente estudo teve por base uma amostra de 100 pacientes felinos (N=100) com exame radiográfico e anamnese disponíveis. Os objetivos principais foram calcular a prevalência de DAD na presente amostra e avaliar a frequência e a gravidade das lesões no esqueleto axial e apendicular. Para isto, os exames radiográficos dos 100 animais foram avaliados por dois observadores quanto à existência de sinais radiográficos compatíveis com DAD e respetivo grau de gravidade. Na população avaliada, a prevalência de sinais radiográficos compatíveis com DAD foi de 38%. Os esqueletos apendicular e axial apresentaram alterações em 24% e 25% dos animais, respetivamente. Existiam lesões simultaneamente na coluna e nas articulações apendiculares em 11% dos animais avaliados. A articulação do esqueleto apendicular mais frequentemente afetada foi a articulação úmero-rádio-ulnar, e a que apresentou lesões de maior gravidade foi a articulação femoro-tíbio-patelar. No esqueleto axial, o segmento da coluna com maior frequência de alterações compatíveis com DAD foi a região torácica. Já a região lombar apresentou scores de gravidade mais elevados quando comparado com os restantes segmentos. Não foi encontrada uma associação estatisticamente significativa entre a presença de sinais radiográficos e o sexo ou a idade. No entanto, foi encontrada uma relação estatisticamente significativa entre a raça do animal e a presença de DAD (p<0,05). A prevalência encontrada (38%) é largamente superior ao número de animais da amostra em que se suspeitava da existência de doença articular (3%). Além de frequente, a DAD é sub-diagnosticada na prática clínica, sendo responsável por provocar dor crónica nos pacientes felinos passando muitas vezes desapercebida quando a avaliação se baseia na anamnese e nos sinais clínicos. Sendo assim, o exame radiográfico e sua correta apreciação reveste-se de extrema importância de modo a identificar e possibilitar o tratamento desta doença.
ABSTRACT - Prevalence of radiographic changes associated with degenerative joint disease in the domestic cat – retrospective study of 100 cases - Degenerative joint disease (DJD) has a multifactorial etiology that involves genetics, biomechanics and biochemistry factors and it is characterized by the degeneration of the cartilage with production of new bone tissue. Its prevalence in the feline population increases with age and its diagnosis takes in consideration the clinical signs as well the radiographic chances. The present study used a sample of 100 feline patients (N=100) with radiographic exams and anamnesis available. The main objective was to calculate DJD prevalence in the sample as well as determine the frequency and severity of these lesions in the axial and appendicular skeleton. To accomplish this, radiographic exams from 100 patients were observed and evaluated by two different observers, who assessed them for the presence of radiographic signs compatible with DJD and respective degree of severity. In the evaluated population, the prevalence of radiographic signs compatible with DJD was 38%. The appendicular and axial skeleton had shown changes in 24% and 25% of the animals, respectively. There were lesions in both spine and appendicular joints in 11% of the population. The most frequently affected joint of the appendicular skeleton was the elbow, and the one that presented with the most severe lesions was the knee. In what concerns to the axial skeleton, the segment of the spine with the highest frequency of compatible with DJD was the thoracic region. The lumbar region presented higher severity scores when compared to the other segments. No statistically significant association was found between the presence of radiographic signs and sex or age. However, a statistically significant relationship was found between the patient’s breed and the presence of DJD (p<0,05. The prevalence of DJD determined (38%) is significantly higher than the number of patients in which it was suspected (3%). DJD is not only frequent and responsible for causing chronic pain in feline patients, but also under-diagnosed in the clinical practice, going unnoticed when the evaluation is based on anamnesis and clinical signs. Therefore, the radiographic examination and its correct evaluation is of extreme importance to identify and make the treatment of this disease possible.

Full textAbstract:
Un alliage métallique complexe (CMA) est un composé intermétallique dont la maille élémentaire est constituée d’un nombre important d’atomes formant bien souvent des aggrégats de haute symmétrie. De la complexité de ces composés peuvent découler des propriétés physico-chimiques intéressantes pour divers domaines d’application. Le système binaire aluminium-iridium est un système qui présente de nombreux composés intermétalliques dont la moitié sont des CMA. Malgré l’étude approfondie dont ce système a fait l’objet dans la littérature, certaines incertitudes demeuraient irrésolues, nous amenant ainsi à réexaminer le diagramme de phase Al-Ir. Nous avons également exploré les systèmes ternaires dits "push-pull" Al-Au-Ir et Al-Ag-Ir, propices à la formation de phases CMA selon certains auteurs. Au total, une centaine d’échantillons ont été préparés par fusion à l’arc puis analysés par diverses techniques de caractérisations: diffraction des rayons X (XRD), microscopie électronique à balayage (SEM), analyse dispersive en énergie (EDS) et analyse thermique différentielle (DTA). Quatre nouveaux composés intermétalliques ont ainsi été identifiés: Al2.4Ir, Al72Au2.5Ir29.5, Al3AuIr et Al11SiIr6, ce dernier étant issu d’une manipulation accidentelle. La structure cristallographique de chacun de ces composés a été résolue, révélant Al2.4Ir et Al72Au2.5Ir29.5 comme étant des CMA possédant une centaine d’atomes dans la maille. Des calculs basés sur la théorie de la fonctionnelle de la densité (DFT) sont venus apporter des précisions concernant la stabilité des composés Al3AuIr et Al11SiIr6. Pour le système Al-Ir, une variante structurale de deux CMA déjà connus de la littérature a également pu être mise en évidence. Les structures cristallographiques de la variante de Al2.75Ir et de celle de Al28Ir9 ont ainsi été approchées, présentant 240 et 444 atomes dans leur maille respective. Les propriétés de surface comptent parmi les aspects les plus intéressants des CMA, par exemple pour la catalyse hétérogène. En l’absence de monocristaux de taille macroscopique, nous avons étudié la possibilité de former des composés de surface par dépôt de Ir sur une surface Al(100) suivi de recuits. Des caractérisations par diffraction d’électrons lents (LEED), spectroscopie de photoélectrons excités par rayons X (XPS) et microscopie à effet tunnel (STM) supportés par ces calculs ab initio ont révélé qu’à partir de 320°C, le composé Al9Ir2 se formait en surface mais également dans une partie du volume du substratA complex metallic alloy (CMA) is an intermetallic compound whose unit cell contains a large number of atoms oftenly forming highly-symmetric clusters. From the complexity of these compounds can arise physical and chemical properties interesting for various fields of application. The aluminium-iridium binary system exhibits numerous intermetallic compounds of which half of them are actually CMAs. Despite this system being extensively studied in the literature, some uncertainies remained unsolved, leading us to reinvestigate the Al-Ir phase diagram. In addition, the "push-pull" systems Al-Au-Ir and Al-Ag-Ir, favorable for the formation of CMA according to the literature, have been explored. Thus, near a hundred of samples have been prepared by arc-melting before being analyzed with different characterizations techniques: X-ray diffraction (XRD), scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS) and differential thermal analysis (DTA). From this study, 4 new intermetallic compounds could be identified: Al2.4Ir, Al72Au2.5Ir29.5, Al3AuIr and Al11SiIr6, the latter being the result of a fortuitous manipulation. The crystallographic structure of each of these compounds has been solved, revealing Al2.4Ir and Al72Au2.5Ir29.5 to be two CMAs with around one hundred of atoms in their unit cell. Calculations based on the density functional theory (DFT) brought further details about the stability of the two other Al3AuIr and Al11SiIr6 compounds. In the Al-Ir binary system, a structural variant of two well-known CMAs has been also unveiled. The crystallographic structures of the Al2.75Ir and Al28Ir9 variant have been approached, revealing 240 and 444 atoms in their respective unit cell. The CMAs oftently exhibit interesting surface properties. In order to study the Al-Ir compound surfaces, iridium adsorption on Al(100) surface followed by annealing has been investigated. The characterizations by lowenergy electrons diffraction (LEED), X-ray photoelectron spectroscopy (XPS) and scanning tunneling miscoscopy (STM) supported by ab initio calculations revealed that, from 320 C, the Al9Ir2 compound is formed at the surface but also in the substrate bulk

Full textAbstract:
The warehouse will be seen as an outlet of décor elements and designer furniture as well as of South African and international décor shops and designs. A showroom of designer furniture (of well-known designers like Rietveld, Graves, Gehry, etc.) for the public and interested and affected parties will be provided. All the different functions must be integrated and the interaction between various designers and different décor elements will form an important aspect of the warehouse. DiD Warehouse must facilitate innovation and welcome new talents among collaborators along with the "design consumer", an informed and sensitive buyer who, by setting in motion a buying project of his own, is transforming distribution. Even retailers will have to change their attitude, and get rid of the "museum store" concept, that is, a space where the objects on display cannot be touched. The warehouse should be seen as an event place, which has a give-and-take relationship with the life and culture of the city and which attracts the visitor, plying him with emotions and services over and above a simple exchange of merchandise and money over a counter. Growth of any kind brings with it an ability to keep changing, doing away with moldy prejudices to make room for the new. Transformation, movement and lightness are, in the end, the words that best sum up the character of what the designer warehouse must be in the future. Time, scale and functional differences must be solved through the design and planning of spaces. The building will be seen as a "container". South African and international influences, as well as space perceptions of the Post-Modernist era, must be incorporated to set a precedent for the warehouse. A true South African influence and modern style will be reflected through the architecture. The furniture and décor elements will form part of the building and architecture, and must complement each other. DiD Warehouse will house historical and current designer furniture and décor elements, to ensure prospects, possibilities and opportunities for designers of the future. Local designers will get exposure to the international design industry, and a standard for each design and designer will be set. Differences versus similarities must positively reflect the diversity of South African and international design. Import and export of designer furniture and décor are going to be very important aspects in the administration and economical management of the warehouse. The architecture and interior design of the warehouse will complement each other and create the same feeling, that of inspiration, creativity, modern design, imagination, reality and exclusivity. a designer masterpiece as well. Every well-known architect has designed a piece of furniture in his/her life The building will reflect its function and the activities within the façade and architecture, and will aim to be time and the relationship between architecture and designer furniture is very important and dynamic. One of the most important functions of the building will be to launch careers and test ideas. The exterior (architecture and façade) will set a standard for what is inside the building and the warehouse will aim to set a precedent for future furniture development in South Africa. The building will strive to be a very important catalyst in generating designer décor and furniture. There is a demand for steady retail, which will revive the industrial and export sector. South Africa remains the powerhouse of the continent and medium to long-term prospects are good. This means that deals that can be successful today will become that much more attractive in the future. The warehouse must encourage other designers to make conscious use of design as a factor in the competitive process. Precedents will be the platform of the final product. The building must be adaptable and flexible to accommodate continuous changes in technology, fashion and the changing environment and way of living of each person. It must be flexible in terms of more possibilities, greater prospects and better investments. Young entrepreneurs must have the opportunity to show their designs. The warehouse will be educational in a theoretical, practical and visual way. Furniture design courses will be held from time to time as well as exhibitions held by entrepreneurs and "young-up-and-coming" designers. That will create contrasts in price and experience. The aim of the thesis is to design a modern designer furniture and décor warehouse (situated in a security business park) to fulfill the needs of the community and industry; to investigate well-known architects and furniture designers theoretical approaches and philosophy towards design; to ensure that DiD Warehouse will be one of its kind in South Africa; to set a market for our local talent and to reflect diversity in today's modern designer furniture and décor; to showcase local and international design for the public and to give everyone easy access to and from the building; and finally, to create a place (warehouse) from another century, not of the past but of the future - based on human relationships, master intelligence, respect and loyalty; which will hold the key to our future in design - the rediscovery of compassion.Dissertation (MArch (Prof))--University of Pretoria, 2003.

Background/Aim: The British questionnaire ECLiPS (Evaluation of Children’s Listening and Processing Skills; Barry & Moore, 2015) aims to profile listening difficulties in children. The questionnaire consists of 38 statements, divided into five subscales, and a short survey with six questions about general health. The purpose of this study was to investigate whether children diagnosed with Developmental Phonological Disorder (DPD) in their preschool years (3-6 years of age) show listening difficulties in early school years (7-10 years). Methods: 113 guardians of children with Developmental Phonological Disorder (DPD) and 44 guardians of typically developing (TD) Swedish children participated in the study. Comparisons were made between the Swedish TD-group and the English reference (ER) group presented in the ECLiPS technical manual. Mean scores between the DPD-group and the TD-group were compared, as well as were the responses on the short survey. The groups were categorized by age and gender. Results: In general, high consistency was found between the ER- and TD-group in half of the comparisons; 7-, 9- and 10-year-old boys and 8-year-old girls. The DPD-group tended to show more symptoms of listening difficulties than the TD-group. However, the symptoms varied in relation to age and gender. For example, girls in the DPD-group had more symptoms in younger than in older ages. The short survey revealed that the DPD-group had a higher prevalence of ear infections than the TD-group. The difficulties seen in the DPD-group were most profound in statements concerning language, literacy and laterality. Conclusion: Our results indicate that listening difficulties as measured with the ECLiPS are more common in children diagnosed with DPD in preschool years, than typically developing children. The strongest indication for difficulties is seen in the statements regarding language and literacy. Bakgrund/syfte: Det brittiska frågeformuläret ECLiPS (Evaluation of Children’s Listening and Processing Skills; Barry & Moore, 2015) syftar till att kartlägga lyssningssvårigheter hos barn. Frågeformuläret består av 38 påståenden, indelade i fem underkategorier, samt en kort enkät med sex frågor rörande generell hälsa. Syftet med den här studien var att undersöka huruvida barn som hade diagnosticerats med fonologisk språkstörning (FS) i förskoleåldern (3-6 år) uppvisade lyssningssvårigheter i tidig skolålder (7-10 år). Metod: 113 vårdnadshavare till barn med fonologisk språkstörning och 44 vårdnadshavare till typiskt utvecklade (TU) svenska barn deltog i studien. Jämförelser gjordes mellan TU barn och den engelska referensgruppen (ER) som presenteras i ECLiPS tekniska manual. Barn med FS och barn med TU delades upp i mindre grupper baserat på kön och ålder, och medelvärdesjämförelser gjordes mellan grupperna. Jämförelser gjordes även av svaren på den medicinska enkäten. Resultat: Generellt sett hade ER-gruppen och barn med TU en hög grad av samstämmighet i hälften av jämförelserna; 7-, 9-, och 10-åriga pojkar samt 8-åriga flickor. Barn med FS tenderade att uppvisa en högre grad av lyssningssvårigheter än barn med TD. Dock varierade graden av symptom beroende på ålder och kön. Till exempel tenderade flickor med FS att uppvisa mer symptom i lägre än i högre åldrar. Svaren från den medicinska enkäten visade att barn med FS hade en högre prevalens av öroninfektioner än barn med TU. De svårigheter som barn med FS uppvisade var tydligast inom påståenden som rör språk, läs- och skrivförmåga och lateralitet. Slutsats: Våra resultat indikerar att de lyssningssvårigheter som mäts med ECLiPS är vanligare hos barn som diagnostiserats med fonologisk språkstörning i förskoleåldern än hos typiskt utvecklade barn. Den starkaste indikationen för svårigheter syns i de påståenden som rör språk-, läs- och skrivförmåga.

O objetivo deste trabalho foi investigar a incidência de carnes DFD (dark, firm, dry) em um frigorífico comercial de frango e determinar as suas propriedades funcionais comparando com as do PSE (pale, soft, exudative) e Normal em filés de peito, Pectoralis major. Para a avaliação da ocorrência desses tipos de cores, as aves das linhagens Cobb e Ross receberam banho calmante, com aspersão de água em temperatura ambiente por aproximadamente 10 minutos, associado à ventilação, imediatamente antes do seu abate. Em seguida, foram sacrificadas e desossadas e os filés foram analisados ao tempo de 90min e 24h post mortem, para coleta de valores de pH e L* e classificados em carnes PSE, Normal e DFD, com base nos resultados de 24h post mortem (n=329). O resultado da incidência foi de 24,92, 73,55 e 1,52% para amostras PSE, Normal e DFD, respectivamente. O valor de L* ao tempo de 90 min post mortem foi de 51,57 (±1,91), 48,55 (±1,94) e 41,67 (±1,80), respectivamente, enquanto para o pH foi de 6,10 (±0,48), 6,31 (±0,59) e 7,15 (±0,43) para carnes PSE, Normal e DFD, respectivamente. Após 24h post-mortem os resultados foram para L* 54,32 (±1,09), 50,56 (±1,64), 42,23 (±1,80) e para o pH 5,69 (±0,14), 5,78 (±0,14), 6,05 (±0,43) respectivamente para amostras PSE, Normal e DFD, significativamente diferente (P<0,05). Para o estudo das propriedades funcionais, amostras (n=374) foram selecionadas nas linhas de produção, classificadas em carnes PSE, Normal e DFD de acordo com o L* e pH 24h post mortem. Foram realizadas as medidas do exsudado formado, perda de umidade durante o cozimento e estabilidade da emulsão. Os resultados encontrados na medida do exsudado foram 4,73 (±2,61)%, ,55 (±2,16)%, 1,11 (±1,01)% para PSE, Normal e DFD respectivamente, significativamente diferentes (P<0,05). A medida da perda de umidade durante o cozimento para as amostras PSE foi de 26,03 (±2,93)%, para o grupo Normal a quebra foi de 25,38 (±3,96)% e para o grupo DFD 22,89 (±2,65)%. Entre as amostras dos grupos PSE e Normal não ocorreu diferença significativa (P<0,05), apesar da leve tendência para menor quebra de peso para grupo considerado Normal, enquanto que a quebra de peso para o grupo Normal e DFD apresentou resultados significativamente diferentes (P<0,05) com diferença significativa de 2,50% para DFD. Finalmente, para a medida de instabilidade da emulsão os resultados foram 1,04 (±0,32)%, 0,78 (±0,20)%, 0,70 (±0,12)%, respectivamente para PSE, Normal e DFD, significativamente diferente (P<0,05). Concluindo, as matérias-primas que apresentam características DFD tendem a conferir melhor qualidade funcional com melhor capacidade de absorção, retenção de umidade, baixo exsudado e baixa perda durante o cozimento. A constatação da diferença nas cores do filé na linha de processamento pode padronizar os processos contribuindo para a distribuição adequada das amostras de carne PSE, Normal e DFD especificamente para diferentes tipos de processamento trazendo benefícios econômicos às industrias e qualidade sensorial aos consumidores.The objective of this work was to investigate the incidence of DFD (dark, firm, dry) meat, in a commercial chicken plant and to determine its functional properties in comparison to PSE (pale, soft, exudative) and Normal breast fillet, Pectoralis major. In order to evaluate the occurrence of different color types, commercial Cobb and Ross chickens were submitted to water shower and ventilation treatments during 10 minutes immediately before slaughtering. Birds (n=329) were sacrificed, deboned and analyzed after 90 minutes and 24h post mortem for pH and L* values evaluation and submitted to classification as PSE, Normal, DFD meat based upon 24h post mortem samples. The occurrence was 24.92, 73.55 and 1,52% for samples PSE, Normal and DFD meats, respectively. L* values for 90 minutes post mortem were 51.57 (±1.91), 48.55 (±1.94) and 41.67 (±1.80), respectively, while for pH values were 6.10 (±0.48), 6.31 (±0.59) and 7.15 (±0.43) for PSE, Normal e DFD meats, respectively. After 24h post-mortem, L* values results were 54.32 (±1.09), 50.56 (±1.64), 42.23 (±1.80) for PSE, Normal and DFD meats, respectively, and pH values were 5.69 (±0.14), 5.78 (±0.14), 6.05 (±0.43) respectively for PSE, Normal and DFD meats. All results were significantly different (P<0.05). For functional properties evaluation, samples (n=374) were selected from production lines and ranked as PSE, Normal e DFD meats according to L* and pH 24h post mortem. Measurement for formed exudate, cook drip loss and emulsion stability was carried out. Results for formed exudate were 4.73 (±2.61), 2.55 (±2.16), 1.11 (±1.01)% for PSE, Normal e DFD meats, respectively and for cook drip loss for PSE 26.03 (±2.93), for Normal 25.38 (±3.96) and for DFD 22.89 (±2.65)%, respectively. No significantly difference (P<0,05) was found between PSE and Normal samples although there was a tendency for lower weight loss for normal group while between normal and DFD samples a significantly difference (P<0.05) was found. Finally, for emulsion estability results were 1.04 (±0.32), 0.78 (±0.20), 0.70 (±0.12)%, respectively for PSE, Normal and DFD samples, significantly different (P<0,05). In conclusion, broiler breast fillet meat which presents DFD characteristics tends to have better functional properties for water holding capacity, lower exudate formation and lower cook drip loss. The standardization of colour differences detection in broiler fillet meat in the processing line could direct these samples specifically to PSE, normal and DFD meats for processing meat products accordingly in order to have economical benefits to the poultry industries and particularly sensorial meat products improvement for consumers.

Full textAbstract:
Duchenne and Becker muscular dystrophies (DMD, BMD) are allelic X-linked diseases which affect approximately one in 3500 male newborns. They are caused by mutations in a gene positioned on the short arm of the X chromosome at Xp21. The first indication of the location of this gene was the description of rare females expressing DMD and who were found to have constitutional X;autosome translocations with an X chromosome breakpoint at this site. There are now 24 such females known worldwide. They express DMD as a consequence of preferential inactivation of the normal X chromosome. In order to contribute to the understanding of the aetiology of mutations causing DMD and the aetiology of constitutional translocations, two types of study have been performed here. Firstly, the detailed mapping of the X chromosome breakpoints of DMD-associated X;autosome translocations has been investigated. The results of this study have been compared with data on the physical distribution of mutations causing DMD in male patients. Secondly, one translocation, an X;l translocation with an autosomal breakpoint at Ip34, has been selected for more detailed investigation and the DNA sequence has been determined at the site of the rearrangement. Translocation breakpoint mapping studies were performed by somatic cell hybrid analysis. Hybrids were karyotyped and this information was used to construct a hybrid panel for the purpose of determining the autosomal localisations of anonymous DNA probes. The mapping of seven probes using this panel is described. The work described in this thesis revealed that the distribution of translocation breakpoints within the DMD gene appears to be random and may differ from the distribution of mutations in male patients. The X;l translocation whose breakpoints are cloned and sequenced was found to involve two expressed loci, one coding for dystrophin on the X chromosome and one for the leukocyte antigen related protein on chromosome 1. Sequence data revealed that a deletion of four to seven nucleotides from the X chromosome and a duplication of two to five nucleotides are associated with the translocation. The possible involvement of trinucleotides adjacent to the breakpoints, and of a LINE, a SINE and a stretch of potential Z-DNA within 1 kb of the X chromosome or the chromosome 1 breakpoint, is discussed.

Mestrado em Engenharia de Computadores e TelemáticaAs ferramentas de Front e Back Office baseadas em serviços Web são actualmente uma realidade comum. Estas fornecem ao utilizador, independentemente do local ou mesmo do terminal, dentro de certos contextos, uma interface única e diferenciada consoante o perfil do utilizador. Para cada perfil, estas interfaces fornecem unicamente o conjunto de comandos e informações necessárias. A plataforma de DSD, onde já se gerem muitas das informações que se relacionam com o processo de manutenção do DETI, tem múltiplos utilizadores com perfis e objectivos muito diferentes. Este documento começa com um estudo do estado inicial da plataforma existente de forma a identificar toda a sua funcionalidade. Posteriormente, é realizada uma análise das novas tarefas a implementar, utilizadores e respectivo modelo de domínio de forma a conhecer toda a nova base estrutural da plataforma. Finalmente é analisada a interface da plataforma a nível de usabilidade para garantir a satisfação dos utilizadores. Toda a plataforma está desenvolvida a pensar em futuras evoluções para continuar a evoluir e trazer valor à organização interna dos departamentos universitários.
The tools of Front and Back Office based on Web Services are nowadays a common reality. These give the user, regardless of location or terminal, within a certain context, a single interface that varies depending of the user profile. For each profile, these interfaces provide only the necessary set of commands and information. The DSD platform, which is already generating a lot of information, related with the managing process of DETI, has multiple users with very different profiles and objectives. The work begins with a study of the initial state of the existing platform with the objective of identifying the available functionality. Furthermore, all the new tasks, users and domain model are analyzed in order to define the new structural basis of the platform. Finally, an usability study of the user interface of the platform is performed in order to obtain an acceptable usability level and ensure user satisfaction. The entire platform is developed considering future developments, in order to continue evolving and bringing value to the internal organization of university departments.

This is a book-length work of memoir/creative non-fiction focused around my father’s sudden death and the resulting effects, direct and indirect, on my family and myself. To borrow the disclaimer Maggie Nelson makes at the beginning of her book, The Red Parts:
“This book is a memoir, which is to say that it relies on my memory and consists primarily of my personal interpretations of events and, where indicated, my imaginative recreation of them. Conversations and other events have been recreated to evoke the substance of what was said or what occurred, but are not intended to be perfect representations.”

My novella is about a mine worker and his family. Set in both Lesotho and South Africa, it engages the effects of migrant labour on families in post-apartheid South Africa. Told through the eyes of the different family members, the narrative uses shifting points of view and moves fluidly through time to present an intimate but complex view of the lives of ordinary working class people. It incorporates witchcraft and ghosts to reveal the blurred lines between the realms of life and death. This collection is inspired by my own father who is a former mine worker. I am influenced by Joyce Carol Oates and Chibundu Onuzo's darkly realistic style, Veronique Tadjo’s explorations of migration and death, the family chronicles of Chimamanda Ngozi Adichie and Yvonne Adhiambo Owuor. I am also inspired by female fantasy and horror writers such as those collected in Ann and Jeff VanderMeer’s anthology, Sisters of the Revolution: A Feminist Speculative Fiction Anthology.
