Hallonet, Anne. "Développement et caractérisation d'un matériau composite à base de fibres de lin : application au renforcement de structures en béton par collage externe". Thesis, Lyon, 2016. http://www.theses.fr/2016LYSE1111/document.
Texto completoResumen
Afin de prolonger leur durée de vie et d'assurer la sécurité des usagers, les structures en béton peuvent nécessiter un renforcement au cours de leur durée de service. La technique de renforcement par collage externe, en surface, de composites renforcés de fibres de carbone, de verre ou d'aramide à l'aide de résines durcissant à température ambiante est largement employée pour son efficacité et sa facilité de mise oeuvre. Toutefois l'utilisation à la fois de fibres synthétiques et de matrices polymères produit un impact écologique non négligeable. L'objectif de ce travail de recherche est d'examiner la possibilité d'utiliser des fibres de lin pour le renforcement externe de structures en béton. Les propriétés mécaniques spécifiques et le bilan environnemental avantageux des fibres de lin en font une alternative intéressante aux fibres de verre. Cependant leur origine naturelle conduit à une plus grande variabilité des propriétés, à un comportement en traction non linéaire et une sensibilité accrue à l'humidité. Les principaux objectifs du travail de thèse portent ainsi sur la sélection des matériaux et la mise en oeuvre les plus adaptés, sur l'évaluation des performances du matériau et de son adhérence au support béton et sur une évaluation de la durabilité des propriétés du système. Dans une première partie expérimentale deux méthodes de mise en oeuvre du renfort à fibres de lin (stratification au contact et collage de lamelles rigides) sont développées et caractérisées. Des observations tomographies X confirment la bonne imprégnation des fibres et la cohésion des composites. Les essais de traction révèlent un comportement en traction bilinéaire comme décrit dans la littérature, avec des propriétés d'effort par largeur de bande comparables aux composites de renfort à fibres de verre. La caractérisation des interfaces composite/béton menée par tests de cisaillement à double recouvrement confirme une bonne adhérence qui se traduit par une rupture cohésive dans le substrat béton. La nature des fibres ne semble pas influencer le comportement de l'interface. Les systèmes de renforcement à fibres de lin sont donc capables de reprendre des efforts transmis par cisaillement de façon comparable aux matériaux de renfort à fibres de verre. Dans une deuxième partie des essais exploratoires de durabilité ont ensuite été menés pour vérifier la pérennité des propriétés de ces deux composites de renfort dans un environnement de service. Un vieillissement accéléré artificiel en enceinte climatique est mis en place tandis que des composites à fibres de lin stratifié au contact sont exposés pendant un an à l'environnement extérieur. Un second vieillissement hygrothermique à 70°C est mené pendant 4 semaines. Les dégradations des propriétés des composites à fibres de lin sont comparables à celles de certains composites de renfort à fibres de verre. Malgré la nature hydrophile des fibres de lin, les premiers essais ne montrent pas de dégradations des propriétés qui rendraient le composite impropre à une utilisation comme renfort extérieur de structures en bétonTo extend their life and ensure the safety of users, concrete structures may need strengthening during their service life. The technique of strengthening by external bonding of composites carbon, glass or aramid composites using polymer that are cured at room temperature is widely used for its effectiveness and ease of implementation. Yet the uses of both synthetic fibers and polymer matrices have a significant environmental impact. The objective of this research is to examine the possibility of using flax fibers for the external strengthening of concrete structures. Their high specific mechanical properties and positive environmental balance make them an interesting alternative to the glass fibers. However, they also present a larger variability in properties, a non-linear tensile behavior and high sensitivity to humidity. The main objectives of this thesis involve the selection of the materials and the most suitable implementation, the evaluation of the materials’ performances and adherence to concrete support and a sustainability assessment of those properties. In a first experimental section, two methods of implementation of the flax fiber reinforcement are developed and characterized: by wet lay-up and by bonding of pre-hardened. Tomography observations confirm the good fiber impregnation and cohesion of the composites. The tensile tests show a bilinear tensile behavior as described in the literature, with stress per width at failure comparable to glass fibres strengthening systems. The characterization of composite/concrete interfaces is conducted by double overlap shear tests and confirms a good adhesion which results in concrete failure before the failure of the reinforcement system. The nature of the fibers does not appear to influence the shear behavior of the interface. For glass or flax wet lay-up systems, failure can occur with failure of the composite. Flax fiber reinforcement systems can take up the forces transmitted by shear in a manner comparable to glass composites. In the second part, sustainability tests were conducted to ensure the sustainability of the properties of these two composite reinforcements in a service environment. An artificial accelerated aging test in a climatic chamber is set up while wet lay-up flax fiber composites are exposed to the external environment during a year. A second hydrothermal aging test is conducted for 4 weeks at 70°C. The degradations of the properties of the flax composites are comparable to those of some glass reinforcement composites. Despite the hydrophilic nature of the flax fibers the first tests show no degradation of properties that would make the composite unsuitable for an external reinforcement of concrete structures

Texto completoResumen
2009 beslutade det europeiska fotbollsförbundet UEFA att införa regelverket Financial Fair Play Regulations, för att förbättra fotbollens ekonomiska hälsa. Detta som en följd av en allt mer ansvarslös och irrationell pengahantering bland europeiska fotbollsklubbar, med stora underskott och försenade betalningar som konsekvens. Ett avsnitt i regelverket berör de så kallade ”break-even”-kraven, som sätter begränsningar för hur stora underskott klubbar får visa upp. I vår uppsats har syftet varit att utreda huruvida ”break-even”-kraven är att anse som förenliga med EU-rättsliga konkurrensregler, specifikt art. 101.1 FEUF. Detta då kraven, enligt vår uppfattning, kan anses ha en konkurrenshämmande verkan i form av investeringsbegränsningar och en asymmetrisk effekt på transfermarknaden. För att kunna utreda den rättsliga giltigheten, har vi använt oss av relevant praxis på EU-nivå inom områdena konkurrensrätt och idrott. Eftersom regelverket är så pass nyutkommet, har det ännu inte hunnit prövas rättsligt på EU-nivå. I och med detta, har det för oss funnits stort utrymme för diskussion och hypotetiska scenarion. Vår studie av praxis har visat att bestämmelserna kan bedömas vara förenliga med EU-rätten, trots en konkurrensbegränsande verkan. I vår analys har vi därför, utifrån befintliga förutsättningar, diskuterat huruvida vi anser att ”break-even”-kraven ska bedömas vara förenliga med art. 101.1 FEUF, även om de kan anses ha en konkurrenshämmande effekt. Vi har vägt in både ekonomiska och sportsliga faktorer i vår analys, och har även diskuterat möjligheten till alternativa tillvägagångssätt.

The present studys objective was to analyze the impact of Government regulations on the managing of a Unimed health care co-op in the State of Minas Gerais. Within the context of Government Reform in Brazil, with the approval of Law n. 9.656, in June 1998, the activities of the companies that run private health care plans and insurance (or the segment of supplementary health care) in the Country were regulated. For such a study, a systemic approach to organizational analysis was used, and it dealt with six perspectives, that is, strategic, structural, technological, human, cultural and political. A Unimed health care co-op was chosen to be analyzed. This option was justified, particularly, by the fact that this kind of company is present in most regions and states in Brazil, and it is an alternative to the organizations of the competitive market. The study that was held was exploratory-descriptiveanalytic, and the approach adopted was that of qualitative analysis. Results demonstrated that those interviewed are aware of the environmental forces within this new context, to which the co-op is exposed. They reported that the organization has responded relatively quickly to environmental changes, mainly because a new administration, with a professional outlook, had taken over running the co-op in April 1998. Therefore, regulation offered the chance for this health care co-op to radically change its management style, thus becoming a professional and modern company. Strategic planning was adopted as a management tool, organizational strategies were altered, a new structure was implemented, deep and sweeping innovations were introduced in the technological area, and human resources relations were also changed. A highly qualified managerial team was set up, thus making administrative rationality available to the Unimed health care unit studied, which implied in the building a new culture. The restructuring of this organization, made necessary by the demands brought about by the regulation of the industry, has made viable not only its adaptation to this new context but also its survival and even its growth.O presente estudo teve por objetivo analisar impactos da regulamentação estatal na gestão de uma cooperativa médica Unimed do Estado de Minas Gerais. No contexto de Reforma do Estado no Brasil, com a promulgação da Lei n. 9.656, em junho de 1998, foram regulamentadas as atividades das empresas que operam com planos e seguros privados de saúde (ou segmento de assistência médica suplementar) no País. Para realizar este estudo, utilizou-se uma abordagem sistêmica de análise organizacional, que contemplou seis perspectivas, quais sejam, estratégica, estrutural, tecnológica, humana, cultural e política. Foi escolhida, como unidade de análise, uma cooperativa médica Unimed. Esta opção se justificou, particularmente, pelo fato de tal modalidade empresarial estar presente na maioria das regiões e estados do Brasil e ser uma alternativa às organizações do mercado competitivo. O estudo realizado teve um caráter exploratório-descritivo-analítico, sendo adotada uma abordagem de análise qualitativa. Os resultados demostraram que os entrevistados têm consciência das forças ambientais desse novo contexto, às quais a cooperativa está exposta. Relataram que a organização respondeu às mudanças do ambiente de forma relativamente rápida, especialmente, porque uma nova administração, com visão de gestão profissional, havia assumido a direção da cooperativa em abril de 1998. A regulamentação foi, portanto, um impulso para que esta cooperativa médica mudasse radicalmente sua forma de gestão, transformando-se em uma empresa profissionalizada e moderna. Adotou-se o planejamento estratégico como ferramenta gerencial, modificaram-se as estratégias organizacionais, uma nova estrutura foi implementada, inovou-se, profunda e amplamente, no campo tecnológico e transformaram-se as relações com as pessoas. A montagem de uma equipe gerencial altamente qualificada com executivos recrutados no mercado dotou a gestão da cooperativa médica Unimed estudada de racionalidade administrativa, implicando a construção de uma nova cultura. A reestruturação desta organização, impulsionada por demandas provocadas pela regulamentação do setor, está viabilizando não somente sua adaptação a este novo contexto como também a sua sobrevivência e, até mesmo, seu crescimento.

Texto completoResumen
The Fast Factorized Back Pro jection (FFBP) algorithm is a computationally efficient
algorithm for image formation in a Very High Frequency Synthetic Aperture Radar (VHF
SAR) system. In this report an investigation of the feasibility of using an FPGA with a
hard CPU core to calculate the FFBP in real-time has been done. Two System on a Chip
designs for this task have been proposed for calculating the FFBP. A simplified version of
the FFBP has also been implemented in Matlab and used during this pro ject. The result
is that the computationally intensive parts, such as index generating and interpolation
calculations, should be implemented in the logic part of the FPGA and the CPU should
handle scheduling. This kind of modular system is easy to maintain and upgrade.

Title: Perishable Inventory Management Solutions and Challenges of Kosovo FFRs. Avoiding Product Expiration at Retails ShelvesPurpose: In this thesis perishable inventory management solutions and challenges at Kosovo FFRs have been studied and identified. Hence, after identifying PIM solutions and challenges the research suggests ideas that will contribute to avoid the expiration of perishable products if selling them takes more time than their actual shelf life. This contributes to minimizing food waste in food supply chains and fresh food retailers. Methodology: Thesis consist of qualitative methods where multiple case studies in cooperation with Kosovo FFRs have been performed. Data collection methods included semi structured interviews, site visits and some financial data accessed from annual and government reports. Theory: Theoretical chapter has been developed from preexisting theory on perishable inventory management. Five phases of fresh food retailing inventory management have been developed and used as the basis for practical research. Moreover, part two of the theoretical chapter talks about the perishable inventory management challenges and is the basis for the second research question. Findings: The findings have shown that Kosovo FFRs use a mixture of PIM solutions with a focus on shelf life and replenishment solutions. The study also revealed that Kosovo FFRs are outdated regarding to product identification and software solutions, however, manage to perform somehow satisfactorily. Consequently, because of the lack of contemporary identification technologies Kosovo FFRs PIM challenges where found to be related to data accuracy and real time data access.

Texto completoResumen
Includes bibliography.The need to provide quality indoor coverage for mobile network users in an indoor environment has become paramount to communication service providers (CSPs). Femto-cells due to their low capital expenditure (CAPEX) and operating expenditure (OPEX) have seen widespread adoption as a possible solution to the indoor coverage challenge. The major drawback of its adoption is the possibility of erratic but significant interference to both the Femto-cell and the Macro-cell tiers owing to their Ad-hoc mode of deployment. The Fractional Frequency Reuse (FFR) is an interference mitigation scheme, due to its effectiveness and low complexity; it has been proposed to be an efficient technique of solving the problem of interference in the cross-boundary region. In this study, a critical analysis of the existing schemes revealed that Femto-cell users at the border between the cell centre region (CCR) and the cell edge region (CER) suffer cross-boundary interference. An algorithm that integrates a buffer zone between the existing CCR and CER has been developed to solve the cross-boundary interference challenge experienced by the Femto-cell users. A system level simulation implemented in MATLAB was used to evaluate the developed algorithm. The network performance (in terms of user-achieved signal-to-interference-plus-noise ratio (SINR) and its daughter metrics such as channel capacity and throughput) was estimated. In terms of the SINR, the performance improvement recorded for Femto-cell users at the border region after the implementation of the buffer zone was more than eighty per cent (80%). There were significant improvements in terms of the channel capacity and throughput for the Femto-users present at the buffer region with the implementation of the developed algorithm.

Texto completoResumen
In this thesis a distributed, dynamic, load aware, joint power and frequency allocation protocol for 4G networks along with system-level simulated results are presented. In all cellular networks, a key limiting factor for throughput is inter-cell interference, especially at the cell edges. Several methods have been proposed and adopted in each mobile network generation to cancel or suppress its effects, whereas each method has its drawbacks in terms of receiver complexity or additional control nodes. However, the proposed protocol presented here does not impose any architectural changes. In 4G networks such as LTE, the choice of OFDMA for the air interface has paved the way for selective frequency and power allocation in the available spectrum. Taking advantage of this opportunity, fractional frequency reuse (FFR) has been proposed in OFDMA based mobile networks in order to reduce the throughput loss at the cell edges due to inter-cell interference. In FFR, center users lose part of available spectrum that is dedicated to the edge users. Our protocol aims to minimize this loss of center users incurred by FFR, at the cost of minimal degradation at the edges. An eNodeB, only when overloaded, requests its neighbours’ edge band to be used for its center users at a reduced power level. This is done via small message exchange between the eNodeBs. The neighbors of the overloaded eNodeBs solve a small local knapsack problem to decide whether band lending is feasible or not. A distinguishing feature of this protocol is the power level adjustment for the borrowed band, which is mutually decided by the borrower and lender. The band is released when it is not needed or it is causing unacceptable loss to the lender. The implementation is done in a Matlab based LTE system level simulator. For the implementation of our protocol in the simulator, starting point was implementation of FFR-3 functionality, a prerequisite and a baseline for comparison with our protocol. Results are compared among three different setups of re-use1, FFR-3 and our protocol by varying number of overloaded eNodeBs for various numbers of scenarios and the comparison is made based on the center users’ throughput, edge users’ throughput. An estimation of time and protocol overhead is also presented. We have observed center users’ throughput gain up to 46%, at the cost of 9% edge users’ throughput loss, when compared to the classic FFR-3 scheme. The overall system throughput goes up to 26 % in heavily loaded scenario. The utility of the protocol for an LTE system is evident from the results, which is supported by the dynamic and decentralized nature of the protocol. This ensures better utilization of spectrum, by temporarily allocating more bandwidth where it is needed more.

Texto completoResumen
Le malattie cardiovascolari, e in particolar modo l’aterosclerosi, costituiscono attualmente la principale causa di ospedalizzazione e mortalità nei paesi occidentali. Questa patologia porta allo sviluppo all’ interno del vaso sanguigno di placche, che negli stadi avanzati della malattia, possono portare ad una parziale o completa occlusione.
In base alle attuali linee guide, la diagnosi della patologia aterosclerotica prevede che il paziente venga sottoposto ad una serie di test provocativi non invasivi volti a documentare i segni indiretti della malattia. In presenza di tale documentazione il paziente viene sottoposto a coronarografia al fine di confermare la malattia aterosclerotica e in tal caso di procedere con tecniche di rivascolarizzazione.
Negli ultimi anni è apparso evidente il limite di questo percorso sia per quanto riguarda la non infallibilità dei test provocativi in termini di sensibilità e specificità, e sia per quanto concerne i limiti stessi della coronarografia. A tal proposito, in questo lavoro, vogliamo presentare nuove tecniche che potrebbero cambiare gli scenari della cardiologia e analizzare i vantaggi che queste possono portare in termini di costi per il sistema nazionale e di qualità di vita per il paziente.

Texto completoResumen
La problématique générale de cette thèse est le manque de standards et de références pour le design et pour l'utilisation des mesures en génie logiciel. Cette problématique rend le processus de mesurage des logiciels complexe et difficile. La méthodologie adoptée pour résoudre la problématique indiquée ci-dessus est à la fois exploratoire et qualitative.
L'objectif de cette thèse est la construction d'un référentiel pour la mesure des logiciels. Le référentiel est composé de huit étalons de mesure des logiciels. Dans notre contexte, un étalon est défini comme «une mesure matérialisée, appareil de mesure, matériau de référence destiné a définir, réaliser, conserver ou reproduire une unité ou une ou plusieurs valeurs d'une grandeur pour servir de référence» (ISO, 1993).
Ces étalons de mesure traitent un seul attribut du logiciel, soit la taille fonctionnelle, et ils touchent trois types de logiciels: applications de gestion, systèmes en temps réel et systèmes hybrides. Pour mesurer la taille fonctionnelle, ces étalons utilisent une mesure appelée les points de fonction (en anglais Function Point Analysis - FPA).
«FPA, introduced in 1979 by Allan Albrecht, was proposed to help measure the productivity of software development. Function points have the advantage of well-known norms and well defined detailed procedures that allow a uniform method of counting and the establishment of a reference base for making comparisons, provided, of course, that the rules of calculation and accounting are correctly applied.» (Abran, 1994)
Pour la construction du référentiel, une méthode de mesure des logiciels bien spécifique a été choisie, soit COSMIC-FFP (ISO 19761). COSMIC-FFP est une méthode rigoureuse de mesure des logiciels. Elle rend possible la mesure de la taille des logiciels tels qu'ils sont perçus par leurs utilisateurs, c'est-à-dire à travers les besoins fonctionnels. Le résultat de l'application de la mesure donne une valeur numérique qui quantifie la taille fonctionnelle du logiciel. Les raisons de la sélection de cette mesure spécifique et sa description sont expliquées dans le quatrième chapitre.

Texto completoResumen
Depuis la fin des années 70, un certain nombre de mesures de taille du logiciel ont été proposées, sans toutefois être suffisamment normalisées pour être utilisées de façons fiables et cohérentes. De plus, pour les méthodes de mesure de la taille fonctionnelle des logiciels 1, l'industrie reproche principalement les coûts et les délais d'obtention d'une mesure. La formation du personnel"expert" est aussi une source d'investissement importante qui a fait reculer plus d'une entreprise. L'automatisation semble donc une solution. L'automatisation de la mesure fonctionnelle de la taille a été tentée dans le passé, mais avec peu de succès. Les raisons sont les suivantes : (1) il est relativement difficile d'automatiser une méthode de mesure fonctionnelle dont les règles n'ont pas été adaptées aux principes du génie logiciel ; (2) la pratique actuelle en génie logiciel indique une faiblesse de la documentation du logiciel, si ce n'est l'absence de documentation. La mesure fonctionnelle de la taille est cependant nécessaire, car cette mesure est un maillon essentiel pour : (1) construire des modèles de productivité ; (2) aider à mieux estimer le coût des logiciels avant leur construction ; (3) évaluer le port-folio des logiciels des entreprises. Dans les dernières années, la création d'une mesure de taille fonctionnelle du logiciel plus conforme aux principes du génie logiciel devrait faciliter son automatisation. Il s'agit de COSMIC-FFP. Cette nouvelle méthode ne peut résoudre les problèmes relatifs à la qualité de la documentation, c'est pourquoi notre travail s'en tient à la mesure des logiciels dont la documentation est disponible. L'objectif principal de notre travail est de concevoir un outil de comptage automatique pour la méthode de mesure de la taille fonctionnelle COSMIC-FFP à partir des spécifications du logiciel écrites avec l'outil Rational Rose RealTime. 1 Les principales mesures fonctionnelles connues sont Function Point Analysis (FPA), Mark II (surtout en Europe), Feature Points (un sous-ensemble de FPA), 3D Function Points (un complément à FPA) et COSMIC-FFP.

Texto completoResumen
The coastal population is growing, putting extra stress on coastal sediments and protection features, such as beach dunes. Moreover, global warming will increase the frequency of storms, and coastal dunes and other defense infrastructure will be subjected to increased erosion and scouring, endangering the people they are meant to protect. Understanding soil dynamics and fluid interaction is crucial to predict the effects of sand erosion. In particular, the study of wind erosion of sands in coastal dunes is essential due to the protective role these earthen structures have during storm events.
One of the challenges about predicting wind erosion in coastal dunes is its extended spatial scale and the associated economic and logistics costs of sampling and characterizing the sediments. Because of this, in-situ testing for sediment characterization is essential. In particular, the usage of free-fall penetrometers (FFP) is appealing due to their portability and robustness. The sediment properties obtained with this type of testing can later be used to assess wind erosion susceptibility by determining, for example, the wind velocity to initiate the erosion process.
FFP testing involves dropping an instrumented probe that impacts the soil and measures the kinematics or kinetics during the penetration process. For example, deceleration measurements are used to compute an equivalent quasi-static failure, which is not in line with the dynamic process characteristic of FFP testing. This preassumed failure mechanism is used to back-calculate the sand's geomechanical properties. However, soil behavior is highly complex under rapid loading, and incorporating this behavior into FFP sediment characterization models is challenging. Advanced numerical modeling can improve the understanding of the physics behind FFP testing.
This thesis presents various advancements in numerical modeling and erosion models to bridge FFP in-situ testing with predicting the initiation of wind erosion of sands. First, improvements oriented to the Material Point Method (MPM) for modeling in-situ FFP testing are proposed. The numerical results show that the simulation of FFP deployment in sands is affected by strain localization and highlight the importance of considering constitutive models sensitive to different loading rates. Because of the importance of rate effects in soil behavior, the second aspect of this thesis proposes a novel consistency framework. Two constitutive models are adapted to study strain-rate sensitive non-cohesive materials: i) a strain-softening Mohr-Coulomb, and ii) a NorSand model. In addition to increased strength, the proposed framework captures increased dilatation, an early peak deviatoric stress, and relaxation.
Finally, a novel sand erosion model is derived using a continuum approximation and limit equilibrium analysis. The erosion law considers geotechnical parameters, the effects of slope, and moisture suction, in a combined manner. The proposed model is theoretically consistent with existing expressions in the literature. It covers a wide range of environmental and geometrical conditions and helps to reconcile the results from FFP testing with the prediction of the initiation of wind erosion. The model was validated in a wind tunnel and is demonstrated to be a viable alternative for predicting sand erosion initiation.
This thesis opens up new research prospects, such as improving the soil characterization models or the direct prediction of sand erosion using rapid, reliable, and efficient in-situ testing methods.Doctor of Philosophy
With global warming and climate change, it is expected that the frequency and intensity of storms will increase. This increment will put extra stress on coastal sediments such as beach sand and coastal dunes, making them prone to erosion. Coastal dunes lose their ability to withstand storms as they erode, potentially making coastal flooding more frequent. In light of this, all stakeholders involved in the protection against coastal disasters must have the tools to predict, prepare for, and mitigate for situations like the ones stated above. An essential aspect of the prediction component is dependent on a successful sediment characterization, for example, determining how much wind the sand can withstand before it erodes. Free-fall penetrometers (FFP) are devices designed to conduct the characterization mentioned above. However, the procedures used to perform this characterization are mainly based on empirical or semi-empirical expressions. Computer models, capable of simulating the physics behind FFP testing, can bring more insight into the process of interaction between FFP devices, sands, and water and can be the basis to improve the characterization methods. The latter results can be utilized for instance to predict wind erosion, including several properties of the sand, such as its mineralogy and shape. This study contributes to developing the computer simulations of FFP deployment and the wind erosion prediction models. Eventually, these developments can help engineers and coastal managers to anticipate and prepare for more frequent coastal hazards.

Texto completoResumen
In 2015 the Swedish Foreign Minister announced that the foreign policy would be feminist. This thesis aims to advance an understanding of the process of institutionalizing feminism in the Swedish foreign policy statements and the effects this has had on Swedish foreign policy priorities. Through a combined approach of constructivist and feminist theory, it is argued that while areas related to feminism, such as women, gender, and equality, have been institutionalizing over the last two decades, the introduction of overt feminism has increased resistance. By drawing on institutionalization theory, gender mainstreaming, and hegemonic masculinity it is revealed how ‘adding women’ has been the main approach but that the use of ‘feminism’ has challenged the hegemonic masculinity embedded in foreign policy. The thesis concludes that aspects of feminism have been institutionalized, however, feminism as a structure is still at its emerging stage internationally. Moreover, it is discussed how the relationship between national and international political spheres affect the institutionalization process of norms cyclically.

Texto completoResumen
Synthetic antenna aperture (SAR) is a pulses focusing airborne radar which can achieve high resolution radar image. A number of image process algorithms have been developed for this kind of radar, but the calculation burden is still heavy. So the image processing of SAR is normally performed “off-line”.
The Fast Factorized Back Projection (FFBP) algorithm is considered as a computationally efficient algorithm for image formation in SAR, and several applications have been implemented which try to make the process “on-line”.
CELL Broadband Engine is one of the newest multi-core-processor jointly developed by Sony, Toshiba and IBM. CELL is good at parallel computation and floating point numbers, which all fit the demands of SAR image formation.
This thesis is going to implement FFBP algorithm on CELL Broadband Engine, and compare the results with pre-projects. In this project, we try to make it possible to perform SAR image formation in real-time.

La tesi contiene una descrizione del sistema cardiovascolare e del circolo coronarico seguita dalla presentazione delle patologie delle arterie coronarie con riferimento alle cause, ai fattori di rischio e all'approccio terapeutico con cui vengono trattate. Successivamente viene descritta la procedura di coronarografia di cui si evidenziano le possibili complicazioni. Si introduce poi tomografia computerizzata di cui di presentano il principio di funzionamento, il processo di ricostruzione dell'immagine e come tali apparecchiature si siano evolute nel tempo fino a giungere ai tomografi di ultima generazione. Infine vengono presi in considerazione alcuni test clinici condotti presso il Centro Cardiologico Monzino di Milano, ovvero la struttura che in Italia è in possesso delle tecnologie di ultima generazione. I risultati prodotti da tali test sono stati analizzati con il fine di validare l'impiego di queste nuove apparecchiature come mezzo diagnostico in caso di sospetta coronaropatia, in sostituzione alla coronarografia ritenuta più invasiva. Si è potuto concludere che l'utilizzo di tomografi di ultima generazione determina un gran numero di vantaggi per il paziente tra cui soprattutto una maggiore qualità dell'immagine, una riduzione dei tempi di acquisizione e una ridotta dose efficace.

Brabazon, Holly Kathryn. "Delimiting Species and Varieties of Cycladenia humilis (Apocynaceae)". BYU ScholarsArchive, 2015. https://scholarsarchive.byu.edu/etd/5921.
Texto completoResumen
Taxonomic delimitation of rare species is vital for accurate assessments of diversity and for their conservation. Cycladenia humilis, the sole species of Cycladenia, is an enigmatic perennial widely dispersed across the western United States. Within this species there are three currently recognized varieties: C. humilis var. humilis in Northern California, C. humilis var. venusta in Southern California, and C. humilis var. jonesii in Utah and Northern Arizona. Some populations occur geographically in areas between the typical distribution of each variety and the presently accepted taxonomy inadequately addresses these populations. Using five nDNA regions, we seek to clarify relationships between current varieties and assess the pattern of variation throughout the species. Analyses including K-means clustering, principle component analysis, fields for recombination, AMOVA, and ecological niche modeling were applied. Results indicate significant genetic structure between varieties and supports recognition of C. jonesii at the species level as distinct from C. humilis. Well defined intraspecific groupings are evident in the data, with evidence supporting the recognition of an additional variety in C. humilis, and two varieties in C. jonesii. Haplotype diversity and relationships between metapopulation clusters inform conservation efforts regarding diversity within Cycladenia and offer insights into the historical demography of this genus.

Efe, Pinar. "A Unification Model And Tool Support For Software Functional Size Measurement Methods". Master's thesis, METU, 2006. http://etd.lib.metu.edu.tr/upload/12607467/index.pdf.
Texto completoResumen
Software size estimation/measurement has been the objective of a lot of research in the software engineering community due to the need of reliable size estimates. FSM Methods have become widely used in software project management to measure the functional size of software since its first publication, late 1970s. Although all FSM methods measure the functional size by quantifying the FURs, each method defined its own measurement process and metric. Therefore, a piece of software has several functional sizes when measured by different methods. In order to be able to compare functional sizes of software products measured by different methods, we need to convert them to each other.
In this thesis study, the similarities and differences between four FSM methods, IFPUG FPA, Mark II FPA, COSMIC FFP and ARCHI DIM FSM are investigated and the common core concepts are presented. Accordingly a unification model of the measurement process of all four methods is proposed. The main objective of this model is to measure the functional size of a software system by applying all four methods simultaneously, using a single source of data. In order to have an infrastructure to validate the unification model by conducting empirical studies, a software tool is designed and implemented based on the unification model. Two empirical studies are conducted by utilizing the data of a real project to evaluate both the unification model proposed and the developed tool and the measurement results are discussed.

Nos seres humanos, o processamento da informa??o sonora possibilitou o aparecimento da linguagem oral e da m?sica. A altura sonora (do ingl?s, pitch), que permite a constru??o da melodia de uma m?sica e da pros?dia no discurso falado, ? um desses atributos. A percep??o da altura ? uma habilidade universal, contudo alguns indiv?duos se destacam por serem capazes de identificar ou produzir um tom em uma altura particular sem o uso de uma refer?ncia externa. Essa habilidade ? popularmente conhecida por ?Ouvido Absoluto? (em ingl?s, absolute pitch ou perfect pitch). No entanto, os mecanismos neurais respons?veis por tal habilidade ainda n?o s?o totalmente conhecidos. O presente trabalho tem o objetivo de contribuir para o entendimento dos processos neurais envolvidos na percep??o de alturas em indiv?duos com a habilidade de Ouvido Absoluto (OA). No nosso primeiro estudo, avaliamos a preval?ncia do OA em uma popula??o local de m?sicos (Escola de M?sica, UFRN). Para isso, utilizamos de ferramentas psicof?sicas e um question?rio. Nesse trabalho inicial, observamos que a habilidade do OA n?o se apresenta como um processo do tipo "tudo-ounada", mas sim com diferentes n?veis de desempenho: desde as pessoas que acertam abaixo do acaso, aumentando gradativamente a performance at? chegar aos 100%. Enquanto limiares tradicionais (~85%) mostraram uma preval?ncia de OA similar ?quela observada em m?sicos da Europa e Estados Unidos, a aplica??o de um limiar estat?stico resultou na detec??o de um n?mero maior de indiv?duos com algum grau de OA. Al?m disso, mostramos que indiv?duos com OA tem maior prefer?ncia de acerto para as chamadas notas naturais (aquelas relacionadas ?s teclas brancas no piano) em compara??o com as notas de teclas pretas (que s?o as notas sustenidas ou bem?is). Encontramos tamb?m que indiv?duos com OA apresentam in?cio mais precoce do treinamento musical. Finalmente, mostramos que quanto maior a profici?ncia musical, maior a preval?ncia dessa habilidade. Num segundo estudo, utilizamos potenciais evocados auditivos do tronco encef?lico (PEATE) para quantificar a ativa??o de n?cleos do tronco encef?lico no processamento de alturas de indiv?duos com OA. Nesse trabalho, mostramos a presen?a de respostas sustentadas (mas n?o transientes) com maior energia em indiv?duos com OA do que em m?sicos sem essa habilidade. Observamos tamb?m que a amplitude dessa resposta sustentada correlaciona-se com o tempo de rea??o em um teste de nomea??o de alturas. Esses resultados sugerem que indiv?duos com OA possuem maior refinamento no processamento da informa??o ac?stica nos primeiros est?gios do processamento auditivo, contribuindo assim para uma maior automatiza??o da identifica??o de alturas. Acreditamos que esses resultados, como um todo, poder?o facilitar entendimento das rela??es entre o desenvolvimento do sistema nervoso e o aprendizado musical, contribuindo assim para a elabora??o de novas t?cnicas de ensino de m?sica e programas de treinamento.
In humans, the processing of sound information allowed the appearance of speech and music. The pitch - which allows the melody of a song and prosody in spoken discourse - is one of these attributes. Pitch perception is a universal skill, however, just a few individuals are able to identify or produce a tone at a particular pitch without an external tonal reference, an ability known as the Absolute Pitch (AP). However, the neural mechanisms responsible for such ability are not yet fully understood. The present work has the objective to contribute to the understanding of the neural processes involved in the perception of pitch in AP possessors. In the first study, we evaluated AP prevalence in a local population of musicians (School of Music, UFRN). For this, we used psychophysical tools and a questionnaire. This first work showed that AP is not an "all-or-nothing" process, but rather that it has different levels of performance: from people that perform below chance, until it increases gradually to 100% of correct answers. While traditional thresholds (~85%) showed a prevalence of AP similar to that observed in musicians in Europe and the United States, the application of a statistical threshold resulted in the detection of a greater number of individuals with some degree of AP. In addition, we showed that AP possessors hit more the natural notes (those with the whitekeys of the piano) than those that are accidental (flat or sharp, i.e. the black keys of the piano). We also observed that AP possessors present an earlier onset of musical training. Finally, we showed that AP was more prevalent in a high proficiency group in comparison to the average proficiency group. In a second study, we used the auditory brainstem evoked potentials (ABR) to quantify the activation of brainstem nuclei in the processing of heights of individuals with OA. In this work, we showed that sustained responses (but not the transient ones) present a higher energy in individuals with AP than in control musicians. We also found that the amplitude of this sustained response correlates with the reaction time in a pitch naming test. These results suggest that individuals with AP have an increased refinement in the processing of acoustic information in the early stages of auditory processing, which would thus contribute to a greater automation of pitch identification. We believe that this thesis will contribute to the understanding of the relationship between nervous system development and musical learning, thus contributing to the development of new music teaching techniques and training programs.

Texto completoResumen
How long would modern society cope with a power outage, what would happen to vital systems that we today take for granted in modern society. The Nordic electricity grid is facing a major shift where electricity production from non-renewable sources are to be replaced increasingly by renewable sources. By increasing the penetration of wind and solar power the electric power system might be exposed to disturbances due to decreasing inertia as a result of the electricity transition. Currently the electric power system has different reserves to use to maintain frequency stability but there are other reserves that could help further in the fight for the balance between electricity production and consumption. This project examines whether the new reserve service, fast frequency reserve (FFR), can help the existing frequency containment reserve for disturbed (FCR-D) operation. Therefore, two experiments were conducted using the simulation tool ARISTO, addressing relevant issues involving frequency stability. Motivation for the hypothesis was to investigate if FFR could reduce the frequency transients and improve frequency variations by developing various setups and cases when inertia was retained and when the system inertia was reduced at different stages. The results of the experiments showed that the global minimum frequency, nadir, had increased for all test cases compared to the reference case when using FFR, this proved that the FFR in fact help reducing frequency transients. The results showed furthermore that when the FFR had a duration time of 30 seconds compared to only 5 seconds, the frequency variations could be improved for certain setups for experiment 2.

Texto completoResumen
I takt med att Sveriges elsystem byggs ut och allt större andel elenergi kommer från förnybar och väderberoende elproduktion såsom vind, så ökar även behovet av stödtjänster som kan balansera frekvensen i elsystemet. Frekvensen i elsystemet fungerar som en indikator på om elsystemet är i balans och för att elsystemet ska vara i balans krävs att elproduktionen hela tiden motsvarar elanvändningen. Examensarbetet har utrett möjligheterna att leverera stödtjänster från en redan befintlig vindkraftpark och har även undersökt hur möjligheterna ser ut i framtiden i och med att marknaderna för stödtjänster utvecklas. I dagsläget finns fem olika frekvensreglerande stödtjänster i Sverige. Dessa är Fast frequency Reserve (FFR), Frequency Containment Reserve-Normal (FCR-N), Frequency Containment Reserve-Disturbance (FCR-D), automatic Frequency Restoration Reserve (aFRR) och manual Frequency Restoration Reserve (FRR). Dessa stödtjänster upphandlas av Svenska kraftnät för att upprätthålla balans mellan produktion och konsumtion i elsystemet. För varje stödtjänst finns olika krav och specifikationer som bland annat vilken frekvens som de aktiveras vid, hur lång tid aktiveringen får ta samt hur långt i förväg de upphandlas etcetera. I kontakt med sakkunniga och i litteratur så framgår det att det är möjligt att leverera någon typ av frekvenstjänst från de allra flesta vindparker. För att börja leverera stödtjänster krävs att vindturbinen har en effektomriktare, vilket de flesta vindkraftverk har i dagsläget. Därefter handlar det främst om program och mjukvaruinställningar i effektomriktaren. Annars fungerar det i stort sett som vanlig pitch-reglering av turbinerna. Inom detta projekt så har även driftdata från en verklig vindpark i Blaiken studerats, där tre olika testkörningar genomförts. I testkörningarna har man testat att styra produktionen från turbinerna genom att göra nedregleringar och uppregleringar för att dokumentera hur parken reagerar. Utifrån data från testkörningarna som jämförs med krav för olika stödtjänster kan slutsatser dras om att stödtjänsterna mFRR, aFRR samt FCR-N bör kunna levereras från Blaiken. De är stödtjänsterna med de mest generösa aktiveringstiderna. Resultatet visar även på möjligheter att jobba med parkstyrningssystemet för att förbättra parkens reglerförmåga och i bästa fall skulle detta kunna medföra att parken även klarar kraven för aktiveringstid av FCR-D.

Hoy en día el tamaño del software es utilizado en la gestión y control de producción como uno de los parámetros esenciales de los modelos de estimación que contribuyen a la calidad de los proyectos de software y productos entregables. Aunque la importancia de la medición temprana del tamaño es evidente, actualmente esta medición es solamente alcanzada en fases tardías del ciclo de vida del software (análisis, diseño e implementación).
El tamaño de software puede ser cuantificado usando diferentes técnicas, como las líneas de código y los métodos de medición de tamaño funcional. Un método de medición de tamaño funcional mide el tamaño del software cuantificando los requisitos funcionales. El método Análisis de Puntos de Función (FPA) es el método mayormente utilizado. Este
método fue desarrollado para medir Sistemas de Información de Gestión desarrollados con metodos tradicionales. Aunque IFPUG FPA ha ido alcanzado mayor popularidad en la industria, este método carece de aplicabilidad a todo tipo de software y a nuevos paradigmas de desarrollo.
Para direccionar estas debilidades, COSMIC-FFP ha surgido como un método de segunda generación y ha sido probado como un estandar internacional (ISO/IEC 19761). Sin embargo, la generalidad de COSMIC-FFP requiere ser instanciado por medio de un procedimiento más específico y sistemático en conjunción con un método de desarrollo de software.Condori Fernández, ON.

Network multiple-input multiple-output (MIMO) aims to mitigate the inter-cell interference and improve the performance of cell-edge users (CEUs) through a multi-cell cooperative transmission. The study of network MIMO on top of the fractional frequency reuse (FFR) cellular system has recently attracted more research attention. However, they were not aware that how cell sectorization is done can cause a great influence on system capacity. Another important topic rarely seen is power management for a multi-cellular coordination scenario, where each BS has to simultaneously serve its intra-cell users and some inter-cell CEUs using a limited amount of power. This paper investigates the cell sectorization and power management on top of FFR-based network MIMO systems. Simulation results show that the proposed power management can improve the signal quality of other cells’ CEUs and meanwhile not degrade the performance of intra-cell users. It is shown that there exists a method of sectorization that causes less interference to cell-center users (CCUs) and offers better signal quality to CEUs in a multi-cell cooperative transmission.

Database is the common tool for data archive nowadays. It is valuable to obtain useful data and create new knowledge using data mining technologies to analyze and integrate the tremendous and ever-increasing data. The relational rule method which finds relations in database is the most widespread among the data mining technologies. However, it takes repetitive checking and scanning of the database using traditional relational rule algorithm, and consequently limited the data mining efficiency. This research adopted the FP-Growth as basis and integrated fuzzy partition to propose the Fuzzy Frequent Pattern Growth (FFP-Growth) algorithm that integrated the FP-Growth double database compression and scanning and the fuzzy partition rule to determine the fuzzy group for each item. The feature of this algorithm is that the generate frequent patterns can be created after updating trade database, without re-scanning the original database and therefore improve the data mining efficiency. The fuzzy association rules were investigated from the quantitative trade data in the third part of the research. In addition, due to the fast increase of internet applications, the useful web browse style was explored from web server browsing records. The explored knowledge can be used in marketing and management decision making, and create new business chances.

In this thesis, we construct a mathematical model for FFR (Fractional Frequency Reuse) networks to analyze the blocking probability of handoff call (HC). Because an FFR network consists of two areas：super group (SG) and sectors, three different HCs exist, SG to Sector HC, Sector to SG HC, and Sector to Sector HC. Thus, we can use “mobility” to characterize the moving behaviors of three types of HCs. Mobility is defined as the average moving distance of mobile station (MS) divided by the velocity of MS. To derive the average moving distance of MS, we have to compute the longest moving distance of three types of HCs in different regions. The longest moving distance of the first-type HC is simply the diameter of SG. The longest moving distance of the second-type and the third-type HC can be derived by Pythagorean Theorem and Cosine Theorem respectively. Markov chains model is used to bulid the mathematical model. State transition rates between Markov chains are determined by the initiation and the termination of new calls (NC) and the mobility of the three types of HCs. Finally, we evaluate the blocking probability of three-types HCs from the state transition matrix of Markov chains by varying the velocity of MS, the number of sectors, and the radius of SG.

THESIS ABSTRACT GRADUATE INSTITUTE OF BUSINESS ADMINISTRATION NATIONAL TAIWAN UNIVERSITY NAME：Chao-Min, Cheng DATE：June , 1997 ADVISER：Yi-Long , Jaw The Correlation among Frequent Flyer Programs, Customer Loyalty and Relationship Marketing This research is to discuss the the connection between Frequent Flyer Program(F FP), customer loyalty and relationship marketing from the viewpoints of demand side and supply side. The study of demand side focus on the influences of FFP on the travelers'' decision of choosing airlines and customer loyalty. The study of supply side is to investigate the connection between FFP and relationship marketing. 2 cases are provided, which are China Airline and Eva Airline. 1. Result of the demand side study The travelers don''t put much emphasis on FFP. Besides, the correlation between customer loyalty and FFP is not significant , either. The loyalty is not relativeto the travelers'' emphasis on FFP, age, traveling frequency and income. The correlation between loyalty and gender, purpose of travel, education, occupation are not significant. In general, members of FFP don''t have high loyalty. Most members of FFP think that the airlines only provide primitive service such as customer satisfaction management and periodic update of FFP. The further relationship marketing activities which can build up and maintain more stable relationship are not perceived. 2. Result of the supply side study Instead of taking "strengthening customer loyalty" as the strategic driven, the airlines provide FFP because of competition. Therefore, the level of relation- ship marketing is the lowest one, comparing to higher level of relationship marketing, such as database application and strategic driven. However, if airlines can take FFP as a basis of higher level relationship market -ing and proactively leverage the FFP by database marketing application, more value of FFP can be created. The study also provide suggestions about the application of database marketing, strengthen customer loyalty and relationship marketing.

Abu, Talib Manar. "Exploratory study on an innovative use of COSMIC-FFP for early quality assessment". Thesis, 2007. http://spectrum.library.concordia.ca/975294/1/NR30134.pdf.
Texto completoResumen
The functional size measurement method, COSMIC-FFP, adopted as the ISO/IEC 19761 standard in 2003, was developed by the Common Software Measurement International Consortium (COSMIC). It focuses on the "user view" of functional requirements and is applicable throughout the development life cycle. As some of the software systems targeted by COSMIC-FFP are large-scale and inherently complex, feedback on their functional complexity would facilitate containment of that complexity throughout the software life cycle. In this thesis, a new early quality assessment of COSMIC-FFP models is proposed. The benefits of this work include earlier prediction of the functional complexity of the behavior of software in the COSMIC-FFP context, right from the requirements phase, as well as a mechanism for generating black-box test cases from the COSMIC-FFP model, test case prioritization and test set adequacy monitoring and optimization within given budget constraints, and an early prediction of reliability based on Markov chains. We also present a study of the scales, units and scale types of both COSMIC-FFP and the Entropy-based Functional Complexity Measure that forms the basis of the testing assessment method we propose here. Previous studies have analyzed the scale types of many pieces of software, but not the concept of scale itself, nor how it is used in the design of a measurement method. Two well-known case studies are introduced to demonstrate the applicability of the proposed methods: the Hotel Accommodation System and the Railroad System. We include a formalized COSMIC-FFP definition in the AS-TRM context (Autonomic Systems Timed Reactive Object Model), a language for the formal design of autonomic reactive systems developed at Concordia University. We introduce the Steam Boiler case study to demonstrate the applicability of formalizing COSMIC-FFP in the AS-TRM context. Future work based on this thesis can include the development of AS-TRM specifications for several benchmark case studies, and the collection of COSMIC-FFP measurement data for both the theoretical and empirical validation of the proposed measurement method. The testing method proposed here has been adapted to a specific class of projects, namely Enterprise Resource Planning (ERP) projects, which are perceived to be mission-critical initiatives in many organizations. They can be found in business transformation programs and are instrumental in improving organizational performance.

The eNB (eNodeB) in Long Term Evolution (LTE) system plays an important role to provide the service of UE (User Equipment) requirement in air-interface. Since the traffic load is time variant in the network, when the UEs gathered into one cell’s sector due to a significant activity happened, a large number of UEs within the region increased in the cell that leads to a huge requirement of UEs and load imbalance situation due to unbalanced resource allocation. To cope with the variance in amount of UEs, and the allocation of frequency resources also needs to be adjusted appropriately according to the UE requirement but the adjustment is prone to lead to Inter-Cell Interference (ICI) problem, Commonly used methods are Fractional Frequency Reuse (FFR) and Soft Frequency Reuse (SFR) which can avoid interference to nearby cell through restriction of frequency resources availability in their own cell’s sectors, the available resources of entire cell will be reduced and these methods will not be adjusted their frequency resources according to the different numbers of UEs in each sector, when the network topology has been changed, the allocation of frequency resources and UE average throughput are not equally distributed. In order to resolve above problem, hereby we propose Adaptive Resources Adjustment Method (ARAM) to make adjustment the allocation of frequency resources in each sector to solve the load imbalance issue and find out the available frequency resources that no interference in neighborhood cell’s sectors to improve UE average throughput and resource utility. Based on the simulation result, UE average throughput and resources utilization can be effectively improved beforehand the system reaches full load capacity

In the LTE system, the bandwidth will be divided by the time and frequency into many resource blocks, then user can use these different resource blocks to transmit data. Thus LTE can avoid most intra cell interference. However, due to the cell doesn’t know what the situation of resource allocation by other neighboring cell, they will make interference to each other easily, called inter cell interference. In this situation, the user who is on the cell edge will suffer more interference. Thus, there are many papers proposed to solve the inter cell interference (ICI) problem, such as: FFR (Fractional Frequency Reuse) and SFR (Soft Frequency Reuse). Although these methods can avoid interference to nearby cell through restricting the available frequency resources in their own cell’s sectors, the available resources will be reduced. In addition, when network topology have changed, these methods doesn’t adjust their frequency resources of each sector, as a result, the overall throughput will be reduced. There are some researches proposed dynamic FFR and dynamic SFR to solve aforementioned problems. Although the dynamic adjustment method can enhance the overall throughput, avoiding ICI must be considered. That is, we have to adjust neighbor cell’s frequency at the same time, this will need much of the time to exchange data or massive calculation. So we propose a simple and fast algorithm to dynamically adjust frequency resources which don’t need to adjust neighbor cell’s frequency at the same time but still can avoid ICI.

Recently, with the great competition, the domestic industry airlines have been focusing on developing the relationship with their customers, so that meeting the requirements and enhancing customers’ loyalty have become the very essential concern for all airlines in Taiwan. The purpose of this study is to explore the effects of Frequent Flyer Program (FFP) and perceived justice on customer’s satisfaction and loyalty of airline’s passengers. According to the literature review, the structural equation modeling (SEM) is conducted to evaluate the above issue. By the means of questionnaire, the data are collected from the members of the FFPs like China and Eva airline’s. The results find that customer satisfaction has a positive effect on loyalty. When the customers are satisfied with the interaction justice of the FFPs, then they’ll be more willing to cooperate and develop longer loyal relationship with the airlines. Moreover, the study also found that interactive justice has the most positive effect on customer satisfaction respectively, procedure justice has less positive effect followed. As far as distributive justice is concerned, for the members of the FFPs, the result showed not much effect here. Finally, this study mentioned some managerial implications are implied by the research results, and it may offered some suggestions to future researches.

Feline pancreatitis is the most common exocrine pancreatic disorder with varied mortality. There is no available and reliable method to evaluate the severity and prognosis of the disease. Fresh frozen plasma (FFP) has been reported to treat acute pancreatitis of cats. However, the efficacy has not been determined. Forty-three cats diagnosed as pancreatitis with acute onset of compatible clinical signs and a positive SNAP&;reg; fPLTM Test that hospitalized at NTUVH for therapy between October 2011 and September 2013 were enrolled in this study. All Cats were divided into survival (21/43, 48.8%) and non-survival (22/43, 51.2%) group. Hemoglobin, albumin, BUN, total bilirubin, phosphorous and systolic blood pressure were found to be significantly associated with disease severity and prognosis, and were selected for constructing the system. The severity scores in this study achieved an area under receiver operating characteristic (AUROC) of 0.978. The optimal cut-off point for discriminating outcome was 17.5 with the sensitivity of 95.2% and specificity of 95.5%, respectively. The mortality was 95.5% with a score &;#8805; 18, and 4.8 % with a score &;#8804; 17. In addition, the scoring system can be used to monitor disease progression. The increase in the scores indicate poor outcome. All cats were stratified into Level 1 (score &;#8804;12), Level 2 (score range 12-17), Level 3 (score range 18-30) and Level 4 (score &;#8805; 31) by the severity scoring system. The cats treated with FFP and supportive care was grouped into FFP Group, whereas treated with only supportive care into Control Group. The mortality in Level 1 was 0% in both groups. The mortality in Level 2 was 0% in FFP Group and 33.3% in Control Group. The mortality in Level 3 was 88.9% in FFP Group and 100% in Control Group. None of cats in Level 4 survived. There was no significant difference between different treatment groups, however, the cats treated with FFP in moderate disease stage including Level 2 and 3 showed a trend of lower mortality. In conclusion, the severity scoring system of this study provides a reliable and clinical applicable method to predict clinical outcome in cats with pancreatitis. Treatment combined with FFP is advisable for clinical usage of feline pancreatitis.

RESUMO: As neoplasias mieloproliferativas (NMPs) constituem um grupo de doenças hematopoéticas
clonais resultantes da transformação de células estaminais hematopoiéticas resultando na anormal
amplificação e proliferação de uma ou mais linhagens mielóides. As NMPs são doenças raras, com uma
incidência estimada de 6-10/100.000 indivíduos por ano, apresentando maior incidência em indivíduos
do sexo masculino, caucasianos e idosos.
Neste grupo de neoplasias estão incluídas as NMPs Philadelphia negativas (NMPs-PN), que
englobam três entidades principais, a Policitémia Vera (PV), a Trombocitémia Essencial (TE) e a
Mielofibrose Primária (MFP). Nestas, as mutações V617F (exão 14) e no exão 12 do gene Janus Kinase 2
(JAK2), alterações nos genes que codificam para o recetor da trombopoitina (MPL) e da calriticulina (CALR)
foram identificadas como driver mutations.
Este estudo pretende avaliar o nível de expressão de miRNAs numa população de doentes
caucasianos com NMPs-PN e determinar a validade de miRNAs específicos como um possível biomarcador
minimamente invasivo no seu diagnóstico. Os miRNAsforam selecionados com base em dados publicados
e na regulação das vias de expressão relacionada ao gene da caspase 9 (miR-182-5p e miR-301a-3p), via
JAK/STAT (miR-125b-5p e miR-375-3p) e resistência terapêutica (miR- 203a-3p e 203b-3p).
Um total de 76 amostras de medula óssea fixada em formalina e embebida em parafina (FFEP)
de doentes caucasianos portugueses com NMPs-PN e 36 controlos saudáveis foram avaliados por RT-PCR.
De acordo com os nossos resultados, a doença predominante foi a Trombocitémia Essencial (TE). No que
diz respeito à expressão de miRNAs, não foram identificadas diferenças entre as duas populações: os miR182-5p e miR-301a-3p estão sobreexpressos, o miRNA-375-3p está subexpressos e os miR-125b-5p e miR203a-3p não apresentam tendência.
Deste modo, concluímos que não podemos assumir que esses microRNAs são biomarcadores das
NMPs-PN, uma vez que existe expressão simultânea em doentes e controlos. No entanto, não podemos
excluir essa possibilidade, pois uma caracterização genética mais abrangente poderá contribuir para um
melhor entendimento da patogénese da doença.ABSTRACT: Myeloproliferative neoplasms (MPNs) are a group of clonal hematopoietic diseases resulting from the transformation of hematopoietic stem cells that lead to abnormal amplification and proliferation of one or more myeloid lineages. MPNs are rare diseases, with an estimated incidence of 6-10/100,000 individuals per year, with a higher incidence in males, Caucasians and the elderly. This group of neoplasms includes Philadelphia negative MPNs (PN-MPNs), which encompass three main entities, namely Polycythemia Vera (PV), Essential Thrombocythemia (ET) and Primary Myelofibrosis (PMF). In these, mutations V617F (exon 14) and exon 12 of the Janus Kinase 2 gene (JAK2), Myeloproliferative leukaemia virus oncogene (MPL) and Calreticulin gene (CALR) were identified as driver mutations. The present study aims to evaluate the level of expression of miRNAs in a population of Caucasian patients with PN-MPNs and to determine the validity of specific miRNAs as a possible minimally invasive biomarker in the diagnosis of this group of pathologies. The miRNAs studied were selected and grouped into: relative expression of the caspase 9 gene (miR-182-5p and miR-301a-3p), via JAK/STAT (miR-125b5p and miR-375-3p) and therapeutic resistance (miR-203a-3p and 203b-3p). A total of 76 bone marrow samples fixed in paraffin-embedded formalin (FFPE) from Portuguese Caucasian patients with PN-MPNs and 36 healthy controls were assessed by RT-PCR. According to our results, the predominant disease in the patient population studied was Essential Thrombocythemia (ET). With regard to miRNA expression the miRNAs selected were not differently expressed in both populations: miR-182-5p and miR-301a-3p are overexpressed, miR-375-3p is underexpressed and miR125b-5p and miR-203a-3p do not show any specific tendency. Thus, we conclude that it is not possible to assume that these miRNAs are biomarkers of PNMPNs, since our results indicate that there is simultaneous expression in patients and controls. However, this possibility cannot be excluded, since a more comprehensive genetic characterization may contribute to a better understanding of the pathogenesis of the disease.
