Este trabalho objetivou avaliar a anatomopatologia, o hemograma e o perfil bioquímico sérico de aves de postura inoculadas por Salmonella Gallinarum (SG) contendo os genes cobS e cbiA inoperantes (SGcobScbiA) que mostrou ser avirulenta em trabalhos anteriores, comparando-a com cepas virulentas SGNalr e SGcobS, para mostrar se SGcobScbiA pode ser componente de vacina contra cepas selvagens de SG e S.Enteritidis. 280 pintainhas foram distribuídas em 4 grupos (G); G1 (SGcobS), G2 (SGNalr), G3 (SGcobScbiA) e G4 (controle). Com exceção do G4, os grupos receberam 0,2 mL de suas respectivas cepas contendo aproximadamente 108 UFC/mL de inóculo, aos 5 dias de idade. A eutanásia foi realizada 24h antes (1DAI) e após a inoculação (1DPI), e 3 (3DPI), 5 (5DPI), 7 (7DPI), 10 (10DPI) e 15 (15DPI) dias após a administração do inóculo, sacrificando-se, em cada momento, dez aves de cada grupo. As aves foram sacrificadas, obtendo-se amostras de sangue utilizadas para os exames hematológicos e bioquímicos. Fragmentos de fígado, baço, timo, bursa de Fabricius, rins e coração foram destinados aos exames histológicos. As aves inoculadas com a cepa SGcobS tiveram comportamento semelhante às aves inoculadas por SGNalr, porém com algumas respostas diferentes nos exames hematológicos e bioquímicos. As aves inoculadas com a cepa SGcobScbiA tiveram comportamento semelhante ao grupo controle, entretanto foi verificado alterações brandas em alguns parâmetros, mostrando que estudos futuros devem ser feitos, verificando se as alterações constatadas não irão interferir no desempenho de aves vacinadas com a cepa SGcobScbiA.
The aim of the present study was to evaluate anatomopathology, hemogram and blood serum components of commercial layers experimentally inoculated with SGcobScbiA, which is a Salmonella Gallinarum (SG) strain it shows attenuation of the virulence in previous research and it was compared with high virulence SGNalr and SGcobS strains in order to show if SGcobScbiA has potential to be use as a vaccine against SG and S. Enteritidis wild strains. 280 commercial layers were divided into 4 groups (G); G1 (SGcobS), G2 (SGNalr), G3 (SGcobScbiA) and G4 (control group). With exception of G4, all the other groups received 0,2 mL of their respective strain containing about 108 CFU/mL of the inoculum with five days of age. Birds were sacrificed 24 hours before (1DBI) and 24 hours after the inoculation (1DAI), and three (3DAI), five (5DAI), seven (7DAI) ten (10DAI), and fifteen (15DAI) days after the administration of the inoculum, slaughtering ten birds at a time in each group. Birds were submitted to euthanasia and blood samples were collected in order to make the hematological and blood serum components test. Samples of liver, spleen, thymus, bursa of Fabricius, kidneys and heart were collected for the histological test. The birds inoculated with SGcobS strain had similar behavior when compared with that ones who received SGNalr strain, however some different responses in the hematological and blood serum components were found. On the other hand, the birds inoculated with SGcobScbiA strain had similar behavior when compared with the control group, however, lower alterations in some parameters were found. Further studies must be done to verify if these alterations will not interfere in the performance of the vaccinate birds with SGcobScbiA strain.

Full textAbstract:
This study analyses how Stargate SG-1 perpetuates dominant representations of whiteness, and how whiteness is used as a marker of racial identity in American popular culture. The popular science fiction television show Stargate SG-1 continually uses the nonwhite alien to juxtapose the seeming superiority of the white human, with white Americans acting as trusted gatekeepers for the entire planet. Whiteness becomes almost invisible and normative as the alien “other” requires assistance or containment enacted through SG-1’s adventures “off-world”. I also examine the representation of superior white aliens as an extension of these dominant white discourses.
It is through the study of the constructed nature of “race” that whiteness is made visible. As represented in Stargate SG-1 whiteness discourses contribute to and reflect “common sense” constructions of race within U.S. society. This examination of Stargate SG-1 illuminates how negotiations of whiteness are constructed within United States dominant cultural discourses as a means to exclude the “other”.

A Folha Topográfica de Guapiara 1: 50000 (SG-22-X-B-II-2) situa-se no extremo sul do estado de São Paulo e compreende na porção central da Província Mantiqueira a faixa centro-sul do Cinturão Ribeira. O arcabouço geológico local envolve rochas da sequência metavulcanossedimentar do Supergrupo Açunguí, de idade meso- a neoproterozoicas metamorfizadas e deformadas no Neoproterozoico, associadas a rochas granitoides gerados durante os episódios colisionais ligados ao Ciclo Brasiliano e à formação do Supercontinente Gondwana. Na região, oito unidades litoestratigráficas principais foram mapeadas: metassedimentos da Formação Água Clara e dos grupos Votuverava e Itaiacoca de idade meso- a neoproterozoica, corpos graníticos neoproterozoicos representantes do Granito Três Córregos, corpos graníticos neoproterozoicos a cambrianos do Granito Capão Bonito, rochas sedimentares do Grupo Itararé, intrusivas básicas associadas a Formação Serra Geral e sedimentos recentes Quaternários. O quadro estruturalmetamórfico é determinado dominantemente pelo arranjo tectônico final neoproterozóico, evidenciado nas rochas epimetamórficas por uma evolução estrutural do tipo polifásica. As estruturas primárias S0, devido aos intensos processos de transposição das foliações dúctil e deformação milonítica, apresentamse preservadas de forma escassa em algumas áreas, com predomínio somente do acamamento gradacional reliquiar S0, nas áreas menos deformadas, a um bandamento tectônico nas regiões da zona de cisalhamento. São registradas quatro fases deformacionais e três metamórficas principais: a fase Dn, de baixo a médio ângulo e direção preferencial NE/SW, subparalela ao bandamento composicional S0; a fase Dn+1, de baixo a médio ângulo e direção preferencial NW/SE; a fase Dn+2, de alto ângulo e direção preferencial NE/SW, sendo esta fase a mais penetrativa e a principal e a fase Dn+3, de alto ângulo e direção preferencial NW/SE. Os eventos metamórficos associados são caracterizados pelo metamorfismo M1, o ápice metamórfico, do tipo regional progressivo na fácies xisto-verde alto a anfibolito baixo; M2, do tipo de contato em condições de baixa pressão e baixa a média temperatura, com a formação de hornfels e skarns locais; M3 metamorfismo regional regressivo na fácies xisto-verde baixa.
The Topographic Sheet of Guapiara 1: 50000 (SG-22-X-B-II-2) is located in the southernmost part of the state of São Paulo and comprises the central portion of the Mantiqueira Province, the central-southern belt of the Ribeira Belt. The local geological framework involves rocks from the metavulcanosedimentary sequence of the Açunguí Supergroup, meso to neoproterozoic metamorphosed age and deformed in the neoproterozoic, associated with granitoid rocks generated during the collisional episodes related to the Brasilian Cycle and to the formation of the Gondwana Supercontinent. In the region, eight main lithostratigraphic units were mapped: metasediments of the Água Clara Formation and the Votuverava and Itaiacoca Groups of meso-neoproterozoic age, neoproterozoic granite bodies representing the Três Córregos Granite, granite neoproterozoic bodies of the Capão Bonito Granite, sedimentary rocks of Itararé Group, basic effusives rocks associated with the Serra Geral Formation and recent sediments of the Quaternary. The structuralmetamorphic framework is dominantly determined by the final neoproterozoic tectonic arrangement, evidenced in the epimetamorphic rocks by a structural evolution of the polyphase type. The primary structures S0, due to the intense processes of transposition of ductile foliations and milonite deformation, are sparsely preserved in some areas, with predominance only of the relic gradation bedding of S0, in less deformed areas, to a tectonic banding in the regions of Shear Zone. Four deformational phases and three main metamorphic phases are recorded: the Dn phase, low to medium angle and preferential direction NE / SW, which is subparallel to the compositional bandage S0; The Dn + 1 phase, from low to medium angle and preferential direction NW / SE; The phase Dn + 2, of high angle and preferential direction NE / SW, this being the most penetrative and the main phase and the Dn + 3 phase, of high angle and preferential direction NW / SE. The associated metamorphic events are characterized by the metamorphism M1, the metamorphic apex, of the regional progressive type in the high greenschist to low amphibolite facies; M2, contact type under low pressure conditions and low to medium temperature, with the formation of hornfels and local skarns; M3, regressive regional metamorphism in low greenschist facies.

Full textAbstract:
SG-DBR lasers look to solve many problems associated with present OCT sources by being cost effective, smaller in size, more robust, and by operating at faster repetition rates. Swept Source Optical Coherence Tomography (SS-OCT) requires a tunable laser source that exhibits linear frequency sweeps, large frequency spans, and high repetition rates. This work accomplishes this by using four synchronized waveforms sent to the input of a Sampled Grating-Distributed Bragg Reflector (SG-DBR) laser. Three mirrors control the wavelength, while an internal semiconductor optical amplifier controls the laser output power. In dealing with this complicated tuning mechanism, a manual sweep calibration is too time-consuming. This thesis demonstrates an efficient method for automating the calibration of tunable SG-DBR lasers by implementing a gain medium voltage sensing algorithm, as opposed to the previous inefficient manual efforts.
Experimental OCT tests are also performed by utilizing a Mach-Zehnder interferometer as a device under test to verify the accuracy of the laser calibration methodology. The OCT response to a single reflection event is measured over a range of repetition rates. A method to reduce these spurious display responses caused by wavelength stitching imperfections is implemented through a self-generating optical clock.

Zhang, Haomin. "Essays on customer base concentration, SG&A costs stickiness, and investment efficiency." HKBU Institutional Repository, 2014. https://repository.hkbu.edu.hk/etd_oa/84.
Full textAbstract:
This thesis consists of two essays. Both essays are related to customer base concentration. In the first essay, I examine the impact of customer base concentration on selling, general, and administrative (SG&A) costs stickiness. With a sample of 65,549 firm-year observations from 9,460 unique firms on the US market from 1980 to 2012, I find that concentrated customer base accentuates SG&A costs stickiness, even after controlling for related variables such as asset intensity, employee intensity, firm size and firm age. Further findings indicate that the positive association between customer base concentration and SG&A costs stickiness is enhanced if supplier firms are in durable industry (SIC 3400-3990), or have more relationship-specific investments, but weakened if the duration of the relationship between a supplier firm and its customer base is longer. The findings are robust to alternative measures of major variables and to alternative testing models. In the second essay, I examine the impact of customer base concentration on investment efficiency. With a sample of 57,852 firm-year observations from 12,123 unique firms on the US market from 1980 to 2013, I find that concentrated customer base is positively associated with investment efficiency improvement. The findings are evidenced by the testing results that concentrated customer base strengthens the positive association between investment activities and investment opportunities. From shareholders’ perspective, concentrated customer base also strengthens the contribution of investment expenditure to shareholders’ value. In addition, I find that the positive association between customer base concentration and investment efficiency is influenced by some salient features of the supplier-customer relationship. Generally, such association is more pronounced if the supplier firm’s industry share is larger; if the supplier firm relationship-specific investment is greater; and if the supplier-customer relationship is longer. The findings are robust to a number of sensitivity tests. Keywords: customer base concentration; SG&A costs stickiness; investment efficiency; agency problem; information asymmetry

Sparks, Tim. "Integrated surface water-groundwater modelling : linking surface water and groundwater using DIVAST-SG." Thesis, Cardiff University, 2007. http://orca.cf.ac.uk/54617/.
Full textAbstract:
Surface-water and groundwater are two resources both requiring careful management and protection. Computer modelling of both has long been used as an aid to their management. Historically they have been modelled separately, as their behaviour is represented by different mathematical equations. However, in reality, they are a linked resource each affects the other. DIVAST is a two-dimensional hydrodynamic and water quality numerical model developed for estuarine and coastal modelling. The original model enables the simulation of problems such as pollution and flooding in surface waters. In this study the existing model is extended to allow the modelling of groundwater as well as surface water in the same model. Chapters 1-5 introduce the problem, review some existing models, and then derive, discretise, and implement the equations for surface water and groundwater flow into the new model. Chapters 6-10 test the new model against analytical solutions, laboratory data, field data, and an existing groundwater model (MODFLOW). The outcome is a new version of the DIVAST model, known as DIVAST-SG (Depth Integrated Velocities And Solute Transport in Surface water and Groundwater). It simulates interactions between two-dimensional surface water and groundwater, in addition to the facilities of the original code. The equations are solved within one model, avoiding coupling problems. It is successfully tested against analytical solutions, laboratory studies and field data, and compared to an existing groundwater code, where it successfully models a gravel aquifer adjacent to tidal surface water. A framework is laid for continuing this work to produce a pseudo 3-D surface- water / groundwater code. In addition, novel techniques are pioneered in the laboratory, where open cell foam is used in a tidal flume to represent a porous aquifer adjacent to a river, and a highly detailed dataset of groundwater field data is compiled in the course of the work.

Gilbert, David Wilkey. "Point-Spread Function Assessment of SG-DBR Based Swept Source for OCT Imaging." DigitalCommons@CalPoly, 2012. https://digitalcommons.calpoly.edu/theses/733.
Full textAbstract:
Swept Source Optical Coherence Tomography (SS-OCT) is a medical imaging technique that requires high repetition rate, widely-tunable coherent laser sources. Sampled grating distributed Bragg reflector (SG-DBR) lasers are proven in telecom applications and are expected to fulfill the requirements for SS-OCT at a significantly lower cost than alternative solutions.
Constructed entirely on a semiconductor substrate, SG-DBR lasers require four synchronized waveforms to modulate the output wavelength and intensity. Because of this unique tuning mechanism, there are a number of systematic and noise sources that can affect the quality of the OCT point-spread function (PSF). Based on these noise sources, software is developed to simulate the waveforms in an SS-OCT system and determine the factors that limit width of the PSF central peak and the broadband skirts. Design curves are then created to specify the requirements to obtain a given performance.
Next, experimental tests are performed on a JDS Uniphase C-band SG-DBR laser to assess its performance limitations. Finally, by comparing theory and experiment, recommendations are made on acceptable systematic and random noise errors induced in the PSF.

The optical frequency of the laser is square-wave modulated between two closely spaced wavelengths. These two wavelengths are made time coincident using a fiber based Mach-Zehnder interferometer. From the interferometer, the difference frequency is detected and amplified. The optical difference frequency takes on the form of a microwave signal that can be seen on an electrical spectrum analyzer. The hardware structure of the high-speed wavelength switching SG-DBR package is shown. The wavelength switching architecture and temperature robustness of the laser will also be presented.
Microwave signals up to 17 GHz have been generated by frequency modulating the phase section of the laser. Measured from the microwave signal spectral width, laser linewidth values as narrow as 10 MHz have been achieved for low back mirror current inputs. Linewidth results with respect to device DC bias conditions are also presented. Time resolved frequency step measurements have shown inherent thermal transients of approximately 200 ns upon wavelength switching. From the square wave switching profile, switching times of approximately 24 ns were achieved.

RESUMO – Salmonella Gallinarum (SG) é um patógeno hospedeiro-específico que causa o tifo aviário, doença sistêmica severa que é considerada uma das principais preocupações da indústria avícola mundial. Quando infecta a ave, SG utiliza mecanismos de evasão para sobreviver e replicar no interior de macrófagos. Nesse contexto, os genes phoPQ codificam o sistema regulatório de dois componentes (PhoPQ) que regula genes de virulência responsáveis pela adaptação de Salmonella spp. a fatores antimicrobianos como baixo pH, peptídeos antimicrobianos e baixas concentrações de cátions bivalentes. No presente estudo, objetivou-se investigar a função desses genes para SG. Assim, uma estirpe de SG com genes phoPQ defectivos (SG ∆phoPQ) foi construída e sua patogenicidade avaliada em aves poedeiras de 20 dias de vida susceptíveis ao tifo aviário. SG ∆phoPQ não causou sinais clínicos nem mortalidade em aves desafiadas oralmente, sendo não-patogênica. Ademais, essa estirpe não foi recuperada de fígados e baços. Por outro lado, aves desafiadas subcutaneamente com a estirpe mutante tiveram alterações patológicas discretas a moderadas e baixas contagens bacterianas em tecidos de fígado e baço. A partir dos dados, observa-se que SG ∆phoPQ é atenuado para aves o que sugere que ambos os genes são importantes durante a infecção sistêmica em aves por SG.
ABSTRACT – Salmonella Gallinarum (SG) is a host-restrict pathogen that causes fowl typhoid, a severe systemic disease that is one of the major concerns to the poultry industry worldwide. When infecting the bird, SG makes use of evasion mechanisms to survive and to replicate within macrophages. In this context, phoPQ genes encode a two-component regulatory system (PhoPQ) that regulates virulence genes responsible for adaptation of Salmonella spp. to antimicrobial factors such as low pH, antimicrobial peptides and deprivation of bivalent cations. Herein, we aimed to investigate the role of the mentioned genes to SG. Thus, a phoPQ-depleted SG strain (SG ∆phoPQ) was constructed and its virulence assessed in twenty-day-old laying hens susceptible to fowl typhoid. SG ∆phoPQ did cause neither clinical signs nor mortality in birds orally challenged, being non-pathogenic. Furthermore, this strain was not recovered from livers or spleens. On the other hand, chickens challenged subcutaneously with the mutant strain had discreet to moderate pathological changes and also low bacterial counts in liver and spleen tissues. These findings show that SG ∆phoPQ is attenuated to susceptible chickens and suggest that both genes are important during chicken systemic infection by SG.

La dopamine (da) engendre son effet biologique grace a l'activation de cinq recepteurs (d1-d5) appartenant a la famille des recepteurs a sept domaines transmembranaires couples aux proteines g. Afin d'etudier le role in vivo de d2r, nous avons genere des souris mutantes n'exprimant plus ce recepteur. La locomotion, la coordination du mouvement et les mouvements spontanes de ces souris sont reduits par rapport aux souris normales. Donc, ces souris presentent les symptomes de l'alteration des voies dopaminergiques avec des troubles de la locomotion. Les recepteurs d2 et d3 sont localises au niveau post- et pre-synaptique. Ceci suggere qu'ils puissent reguler la synthese et la secretion de la da, et l'activite electrique des neurones dopaminergiques. Des etudes d'electrophysiologie sur des neurones dopaminergiques des souris mutantes d2-r-/- ont montre que d2-r est l'auto-recepteur qui controle l'activite electrique de ces neurones. La deuxieme partie de ce travail concerne l'etude de la fonction de la proteine sg alpha i2 issue de l'epissage alternatif de l'arnm codant pour g alpha i2. Ce mecanisme remplace les 24 derniers acides amines (aa) de la partie c-terminale de g alpha i2 avec une nouvelle sequence de 35 aa. Sg alpha i2 est localisee au niveau de l'appareil de golgi, tandis que g alpha i2 est localisee sur la membrane plasmique. Des deletions ou des mutations ponctuelles dans la region c-terminale de sg alpha i2 ont montre que un domaine riche en prolines est necessaire pour la localisation de sg alpha i2. De plus, les 35 aa ne sont pas suffisants pour retenir dans le golgi d'autres proteines. Les resultats obtenus suggerent que l'extremite c-terminale ne soit pas le seul domaine responsable de la localisation de sg alpha i2, mais elle specifie plutot l'association a des compartiments cellulaires donnes. La forme constitutivement active de sg alpha i2 n'est plus localisee seulement dans le golgi, mais aussi sur d'autres membranes intracellulaires. Nous avons aussi montre que d2-r interagit avec sg alpha i2. Sg alpha i2 provoque une diminution de la quantite de d2-r a la surface cellulaire par rapport aux cellules n'exprimantes que le recepteur. De plus, nous avons montre que la da engendre une localisation differente de sg alpha i2 et l'augmentation des sites de d2-r a la membrane plasmique. La proteine sg alpha i2 semble donc jouer un role dans le transport de d2-r vers la membrane plasmique.

Full textAbstract:
Metallic quantum clusters are stable structures that can exhibit many useful magnetic, chemical, and optical properties. Developing clusters for specific applications requires accurate methods for characterizing their physical and chemical properties. Most cluster characterization methods are ensemble-based measurements that can only measure the average values of the cluster properties. Single cluster measurements improve upon this by yielding information about the distribution of cluster parameters. This investigation describes the initial results on a new approach to detecting and characterizing individual gold nanoclusters (Au25(SG)18) in an aqueous solution with nanopore-based resistive pulse sensing. We also present a new application where the clusters are shown to increase the mean residence time of polyethylene glycol (PEG) molecules within an alpha hemolysin (αHL) nanopore. The effect appears over a range of PEG sizes and ionic strengths. This increases the resolution of the peaks in the single molecule mass spectrometry (SMMS) current blockade distribution and suggests a means for reducing the ionic strength of the nanopore solute in the SMMS protocol.

Mestrado em Economia Internacional e Estudos EuropeusNa conjuntura atual, o sucesso dos países a nível internacional é uma condição fundamental para o seu crescimento económico. Nas dinâmicas impostas pela globalização, emergem novos protagonistas e novas parcerias estratégicas, onde a língua tem um papel crucial, pelo que, a crescente atenção dos Estados na implementação de medidas, permite explorar as oportunidades nas economias que partilham a mesma língua e estão próximas culturalmente. Uma maior coerência na promoção da presença internacional e a utilização dos recursos endógenos, é fonte de valor acrescentado que cria riqueza, aumenta a produtividade e contribui para alcançar o pleno-emprego. Assim, esta dissertação procura enquadrar a relevância da língua enquanto elemento chave da internacionalização, desenvolvendo igualmente um estudo de caso.
In the current context, a country's economic growth strongly depends on its success at an international level. Among the dynamics imposed by globalization, new protagonists and new strategic partnerships where the language spoken plays a critical role, emerges. Therefore, States have been giving growing attention to the implementation of measures that allow for the exploration of opportunities in the economies that share the same language and culture. A greater coherence in the promotion of international presence and the use of indigenous resources is the source of added value that creates wealth, increases productivity and contributes to reaching full-employment. This thesis assesses the relevance of the spoken language in the internationalization of an economy and studies the case of a specific Portuguese company.

Les observations météorologiques depuis les satellites dans le domaine des micro-ondes sont actuellement limitées à 190 GHz. La prochaine génération de satellites météorologiques opérationnels européens (EUMETSAT Polar System-Second Generation-EPS-SG), em- portera un instrument, le Ice Cloud Imager (ICI), avec des fréquences sub-millimétriques jusqu’à 664 GHz, afin d’améliorer la caractérisation globale des nuages de glace. Pour préparer l’exploitation de ces nouvelles données, durant cette thèse, des travaux ont été effectués sur quatre axes complémentaires. Des simulations réalistes de transfert radiatif ont été réalisées de 19 à 700 GHz, pour des scènes météorologiques réelles, couvrant une grande variabilité des nuages en Europe. L’objectif était double : premièrement mieux comprendre la sensibilité des ondes millimétriques et sub-millimétriques à la phase glacée des nuages, deuxièmement créer une base de données robuste pour développer une méthode d’inversion statistique des caractéristiques des nuages de glace. Un code de transfert radiatif atmosphérique (Atmospheric Radiative Transfer Simulator ARTS) a été couplé avec des profils atmosphériques simulés par un modèle méso-échelle de nuage (Weather Research and Forecasting WRF), pour douze scènes européennes aux moyennes latitudes. Les propriétés de diffusion des hydrométéores (glace, neige, graupel, pluie et eau dans le nuage) ont été soigneusement sélectionnées, en particulier pour la phase glace, et la compatibilité avec la microphysique de WRF a été testée : le Discrete-Dipole approximation (DDA) est adopté pour calculer les propriétés diffusantes des particules de neige. Les simulations obtenues ont été systématiquement comparées avec des observations satellitaires coïncidentes d’imageurs et de sondeurs jusqu’à 200 GHz. L’accord entre les simulations et les observations montre la bonne qualité de la base de données, au moins jusqu’à 200 GHzThe meteorological observations from satellites in the microwave domain are currently limited to 190 GHz. The next generation of European operational Meteorological Satellite (EUMETSAT Polar System-Second Generation-EPS-SG) will carry an instrument, the Ice Cloud Imager (ICI), with frequencies up to 664 GHz, to provide unprecedented measurements in the sub-millimeter spectral range, aiming to improve the characterization of ice clouds over the globe. To prepare this upcoming satellite-borne sub-millimeter imager, during this thesis, scientific efforts have been made on four complementary aspects. Realistic radiative transfer simulations have been performed from 19 to 700 GHz, for real meteorological scenes, covering a large variability of clouds in Europe. The goal was two fold, first to better understand the sensitivity of the microwave to sub-millimeter waves to the cloud frozen phases, and second, to create a robust training database for a statistical cloud parameter retrieval. The Atmospheric Radiative Transfer Simulator (ARTS) is coupled with atmospheric profiles from the Weather Research and Forecasting (WRF) model, for twelve diverse European mid-latitude scenes. The single scattering properties of the hydrometeors (cloud ice, snow, graupel, rain, and cloud water) are carefully selected, especially for the frozen phases, and compatibility with the micro- physics in WRF is tested: the Discrete-Dipole Approximation (DDA) is adopted for snow particles. The resulting simulations have been systematically compared with coincident satellite observations from imagers and sounders up to 200 GHz. The agreement between simulations and observations shows the good quality of the simulated training database, at least up to 200 GHz

O presente trabalho teve por objetivo realizar o mapeamento geológico de uma área, em escala 1:50.000, localizada na região do Morro do Setuva e adjacências, no município de Bocaiúva do Sul - PR, cenário de exposição do Complexo Atuba e das formações Setuva, Capiru e Votuverava. Foram cartografadas onze associações litológicas, três dessas correspondendo ao Domínio do Complexo Atuba: associação dos biotita-hornblenda gnaisses bandados (Pca1), associação dos biotita gnaisses miloníticos (Pca2) e associação dos biotita gnaisses porfiroclásticos (Pca3). No Domínio da Formação Capiru expõem-se cinco associações litológicas, a saber: metarritmitos sito-arenosos (Mc1), metacalcários dolomiticos maciços (Mc2), metacalcários dolomiticos finos bandados (Mc3), quatzitos finos a grossos (Mc4) e filitos avermelhados (Mc5). Para as rochas dessas associações foi postulada sedimentação em sequência regressiva de plataforma rasa. Ao Domínio da formação Setuva correspondem as seguintes associações: sericita xistos (Ms1), quartzitos finos (Ms2) e metacalcário dolomíticos miloníticos (Ms3). A bacia de sedimentação das formações Capiru e Setuva tem sua origem presumida num evento extensional que produziu um rifte inicial evoluindo até atingir condições de margem continental passiva, com uma plataforma estável. No Domínio da Formação Votuverava ocorre uma associação litológica metapelítica (Mv1) e outra de metabasitos (Mv2). Às associações Mv1 e Mv2 foram atribuídos ciclos tectono-sedimentares distintos daqueles nos quais se depositaram as formações Capiru e Setuva; a ZCT Lancinha é considerada o limite tectônico entre este domínio e os demais. O complexo Atuba constitui a infra-estrutura dos metassedimentos das formações Capiru e Setuva com as quais possui contatos marcados por cavalgamentos no sentido WNW\'IMPLICA\'ESE. Este evento promoveu a deformação da Formação Setuva gerando tectonofácies. Evento transpressivo, com geração de dobramentos e zonas de cisalhamento, desenvolveu-se na região, tendo como principal estrutura dobrada a Antiforma do Setuva. O metamorfismo que afetou as formações Votuverava, Capiru e Setuva é do fácies xisto verde, zona da clorita. No Complexo Atuba identificou-se polimetamorfismo com estágios em grau alto, médio e baixo.The presente research was undertaken in the \"Morro do Setuva\" region and neighborhoods, countryside of Bocaiúva do Sul - Paraná, emphasizing geological mapping. In this ares outcrops the Atuba Complex and the Setuva, Capiru and Votuverava formations. The area was mapped in 1:50.000 scale. Eleven associations were mapped and three of them are related to Atuba Complex Domain: bended biotite-hornblende gneisses association (Pca3). The Capiru Formation Domain is represented by five lithological associations: silt-sand meta-rhythmites (Mc1), massive dolomitic meta-limestone (Mc2), fine-coarse quartzites (Mc4) and red phyllite (Mc5). These associations suggested marine regressive sequence to the sedimentation in the shallow carbonate platform. The Setuva Formation Domain corresponds to the following association: sericite schists (Ms1), fine-coarse quartzite and milonitics dolomitic meta-limestones (Ms3). Capiru and Setuva sedimentation basin was originated by an extensional event that produced an initial rift, which reached passive continental margin condition with a stable platform. In the Votuverava Formation Domain occurs meta-pelites (Mv1) and meta-basites (Mv2), Mv1 and Mv2 assigned different tectonic-sedimentary cycles from the ones that were deposited in Capiru and Setuva formations; the Lancinha Shear Zone is the tectonic limit between this domain and the others. The Atuba Complex is the local basemed of Capiru and Setuva formations and with them the complex has contacts through thrust shear zones with WNW-ESE transport. This event was responsible for a wide deformation of Setuva Formation and it had originated tectonofacies. A transpressive event, with major shear zones and associated folding, was recognized, the \"Antiforma do Setuva\" was rhe most important fold register. The metamorphism affected the Votuverava, Capiru and Setuva formations is green schist, chlorite zone. In the Atuba Complex was detected a development under high, medium and low polymetamorphism conditions.

Esta dissertação de mestrado descreve todo o trabalho levado a cabo para comparar numericamente o desempenho aerodinâmico de um perfil com flape simples e com flape morphing do tipo Rotating Rib. Tendo por base trabalhos já efetuados anteriormente, o objetivo principal desta tese é validar resultados experimentais obtidos em túnel de vento. Foram utilizadas ferramentas computacionais de desenho (CAD), para modelar a geometria dos perfis das asas com base nas já construídas, ferramentas de Dinâmica de Fluidos Computacional (CFD), através de cálculo numérico, e ferramentas de pós-processamento para análise de dados. Para melhor definir o modelo a usar foi feita também uma comparação entre os vários modelos, disponíveis nas ferramentas, com dados experimentais validados anteriormente e revalidados noutros estudos. O modelo de turbulência utilizado foi o k-ε Realizable com Standard Wall Functions, uma vez que foi o que se revelou mais próximo dos dados experimentais. Foi feita portanto uma análise bidimensional, com escoamento uniforme e uma solução baseada na pressão com uma formulação absoluta da velocidade. A malha criada é do tipo C com uma zona central tipo O de elevada resolução para melhor definição da camada limite. Os resultados apresentam melhorias significativas por parte do perfil morphing, ao nível dos coeficientes de sustentação e arrasto, o que pode levar ao melhoramento do desempenho da aeronave.This master’s dissertation describes all the work carried out to numerically compare the aerodynamic performance of a regular flapped airfoil to a morphing flapped airfoil of the Rotating Rib style. Based on works previously done, the main purpose of this thesis is to validate experimental results retrieved in wind tunnel. Computational Assisted Design tools (CAD), to model the geometry of the wings’ profiles based on the ones already built, Computational Fluid Dynamics tools (CFD), through numerical calculation, and postprocessing tools, for data analyses, were used. To better define which model to use a comparison between the many available models in the tools with experimental data previously validated and revalidated in other studies. The turbulence model used was the k-ε Realizable with Standard Wall Functions, as it revealed itself as the closest to the experimental data. So a two-dimensional analysis was made, with a steady-state flow and a pressure-based solver with an absolute velocity formulation. The mesh created is a type C with an O type central zone of high resolution for a better definition of the boundary layer. The results show significant improvements concerning the morphing wing, regarding the lift and drag coefficients, which may lead to the improvement of the aircraft performance.

Full textAbstract:
Temporal gravimeter observations, used in geodesy and geophysics to study variation of the Earth’s gravity field, are influenced by local water storage changes (WSC) and – from this perspective – add noise to the gravimeter signal records. At the same time, the part of the gravity signal caused by WSC may provide substantial information for hydrologists. Water storages are the fundamental state variable of hydrological systems, but comprehensive data on total WSC are practically inaccessible and their quantification is associated with a high level of uncertainty at the field scale.
This study investigates the relationship between temporal gravity measurements and WSC in order to reduce the hydrological interfering signal from temporal gravity measurements and to explore the value of temporal gravity measurements for hydrology for the superconducting gravimeter (SG) of the Geodetic Observatory Wettzell, Germany.
A 4D forward model with a spatially nested discretization domain was developed to simulate and calculate the local hydrological effect on the temporal gravity observations. An intensive measurement system was installed at the Geodetic Observatory Wettzell and WSC were measured in all relevant storage components, namely groundwater, saprolite, soil, top soil and snow storage. The monitoring system comprised also a suction-controlled, weighable, monolith-filled lysimeter, allowing an all time first comparison of a lysimeter and a gravimeter. Lysimeter data were used to estimate WSC at the field scale in combination with complementary observations and a hydrological 1D model. Total local WSC were derived, uncertainties were assessed and the hydrological gravity response was calculated from the WSC. A simple conceptual hydrological model was calibrated and evaluated against records of a superconducting gravimeter, soil moisture and groundwater time series. The model was evaluated by a split sample test and validated against independently estimated WSC from the lysimeter-based approach.
A simulation of the hydrological gravity effect showed that WSC of one meter height along the topography caused a gravity response of 52 µGal, whereas, generally in geodesy, on flat terrain, the same water mass variation causes a gravity change of only 42 µGal (Bouguer approximation). The radius of influence of local water storage variations can be limited to 1000 m and 50 % to 80 % of the local hydro¬logical gravity signal is generated within a radius of 50 m around the gravimeter.
At the Geodetic Observatory Wettzell, WSC in the snow pack, top soil, unsaturated saprolite and fractured aquifer are all important terms of the local water budget. With the exception of snow, all storage components have gravity responses of the same order of magnitude and are therefore relevant for gravity observations. The comparison of the total hydrological gravity response to the gravity residuals obtained from the SG, showed similarities in both short-term and seasonal dynamics. However, the results demonstrated the limitations of estimating total local WSC using hydrological point measurements.
The results of the lysimeter-based approach showed that gravity residuals are caused to a larger extent by local WSC than previously estimated. A comparison of the results with other methods used in the past to correct temporal gravity observations for the local hydrological influence showed that the lysimeter measurements improved the independent estimation of WSC significantly and thus provided a better way of estimating the local hydrological gravity effect. In the context of hydrological noise reduction, at sites where temporal gravity observations are used for geophysical studies beyond local hydrology, the installation of a lysimeter in combination with complementary hydrological measurements is recommended.
From the hydrological view point, using gravimeter data as a calibration constraint improved the model results in comparison to hydrological point measurements. Thanks to their capacity to integrate over different storage components and a larger area, gravimeters provide generalized information on total WSC at the field scale. Due to their integrative nature, gravity data must be interpreted with great care in hydrological studies. However, gravimeters can serve as a novel measurement instrument for hydrology and the application of gravimeters especially designed to study open research questions in hydrology is recommended.Zeitabhängigen Gravimetermessungen, die in der Geodäsie und der Geophysik eingesetzt werden, um Variationen des Erdschwerefelds zu messen, werden durch lokale Wasserspeicheränderungen beeinflusst und verursachen – aus dieser Perspektive – ein hydrologisches Störsignal in den Gravimetermessungen. Gleichzeitig bietet der Teil des Gravimetersignals, der durch Wasserspeicheränderungen hervorgerufen wird, das Potential wichtige Informationen über hydrologische Speicher zu gewinnen, da zwar Wasserspeicher eine grundlegende Zustandsgröße hydrologischer Systeme darstellt, jedoch ihre Quantifizierung mit einem hohen Maß an Unsicherheiten auf der Feldskala behaftet ist. Diese Studie untersucht die Beziehung zwischen zeitabhängigen Gravimetermessungen und Wasserspeicheränderungen, um die Gravimetermessungen von dem hydrologischen Störsignal zu bereinigen und um den Nutzen der Gravimetermessungen für die Hydrologie zu erkunden. Dies geschieht am Beispiel des Supraleitgravimeters (SG) des Geodätischen Observatoriums Wettzell in Deutschland. Ein 4D Vorwärtsmodel mit einer räumlich genesteten Diskretisierungsdomäne wurde entwickelt, um die lokalen hydrologischen Masseneffekte auf Gravimetermessungen zu simulieren. Des Weiteren wurde ein intensives Messsystem am Geodätischen Observatorium Wettzell installiert, um die Wasserspeicheränderungen in allen relevanten Speicherkomponenten, also im dem Grundwasser, in der ungesättigten Zone und im Schneespeicher zu messen. Das Monitoringsystem beinhaltete auch einen wägbaren, monolithischen Lysimeter mit Matrixpotentialübertragung, der es uns ermöglichte, zum ersten Mal einen Lysimeter direkt mit einem Gravimeter zu vergleichen. Die Lysimetermessungen wurden in Kombination mit komplementären hydrologischen Beobachtungen und einem 1D-Modell verwendet, um die Wasserspeicheränderungen auf der Feldskala zu bestimmen. Die Gesamtwasserspeicheränderungen wurden bestimmt, Unsicherheiten abgeschätzt und der hydrologische Masseneffekt auf Gravimetermessungen berechnet. Schlussendlich wurde ein einfaches, konzeptionelles, hydrologisches Modell mittels der Zeitreihen von dem SG, Bodenfeuchte- und Grundwassermessungen kalibriert und evaluiert. Das Modell wurde durch einen “Split-Sample-Test” evaluiert und basierend auf unabhängig bestimmten Wasserspeicheränderungen bestimmt auf Grundlage der Lysimetermessungen validiert. Die Simulation des hydrologischen Masseneffektes auf Gravimetermessungen zeigte, dass Wasserspeicheränderungen von einem Meter Höhe entlang der Topographie, einen Erdschwereeffekt von 52 µGal hervorriefen, während in der Geodäsie im Allgemeinen die gleiche Wassermassenvariation in flachem Terrain eine Erdschwereeffekt von nur 42 µGal (Bouguer-Platte) hervorruft. Der Einflussradius der lokalen Wasserspeicheränderungen kann auf 1000 m begrenzt werden, und 50 % bis 80 % des lokalen hydrologischen Erdschweresignals wird in einem Radius von 50 m um den Gravimeter generiert. Wasserspeichervariationen in der Schneedecke, im Oberboden, dem ungesättigten Saprolith und im gelüfteten Aquifer, sind allesamt wichtige Größen der lokalen Wasserbilanz. Mit der Ausnahme von Schnee beeinflussen alle Speicheränderungen die Gravimetermessungen in derselben Größenordnung und sind daher für die Gravimetermessungen von Bedeutung. Ein Vergleich des lokalen hydrologischen Gravitationseffektes mit den SG Residuen zeigte sowohl ereignisbezogene als auch saisonalen Übereinstimmungen. Weiterhin zeigten die Ergebnisse jedoch auch die Grenzen bei der Bestimmung der gesamten lokalen Wasserspeichervariationen mithilfe hydrologischer Punktmessungen auf. Die Ergebnisse des Lysimeter-basierten Ansatzes zeigten, dass SG Residuen mehr noch, als bisher aufgezeigt, durch lokale Wasserspeicheränderungen hervorgerufen werden. Ein Vergleich der Resultate mit anderen Methoden, die in der Vergangenheit zur Korrektur zeitabhängiger Erdschwerebeobachtungen durch Bestimmung des lokalen hydrologischen Masseneffekte verwendet wurden, zeigte, dass die unabhängige Berechnung von Wasserspeicheränderungen durch Lysimetermessungen erheblich verbessert werden kann und dass diese somit eine verbesserte Methode zur Bestimmung des lokalen hydrologischen Erdschwereeffekts darstellt. Die Installation eines Lysimeters ist somit im Zusammenhang mit einer Reduzierung des hydrologischen Störsignals und an Standorten, wo zeitabhängige Erdschwerebeobachtungen für geophysikalische Studien, die über die lokale Hydrologie hinausgehen verwendet werden, zu empfehlen. Aus hydrologischer Sicht zeigte diese Studie, dass die Verwendung von zeitabhängigen Gravimetermessungen als Kalibrierungsdaten die Modellergebnisse im Vergleich zu hydrologischen Punktmessungen verbesserten. Auf Grund ihrer Fähigkeit, über verschiedene Speicherkomponenten und ein größeres Gebiet zu integrieren, bieten Gravimeter verallgemeinerte Informationen über die Gesamtwasserspeicherveränderungen auf der Feldskala. Diese integrative Eigenschaft macht es notwendig, Erdschweredaten in hydrologischen Studien mit großer Vorsicht zu interpretieren. Dennoch können Gravimeter der Hydrologie als neuartiges Messinstrument dienen und die Nutzung von Gravimetern, die speziell für die Beantwortung noch offener Forschungsfragen der Hydrologie entwickelt wurden wird hier empfohlen.

Full textAbstract:
La perte des neurones est consideree comme une des principales causes de la deterioration des fonctions du systeme nerveux central au cours du vieillissement. Cependant, les preuves experimentales d'une diminution du nombre des neurones au cours du vieillissement dit normal en particulier chez l'homme peuvent etre sujettes a caution tant a cause des methodes de comptage cellulaire utilisees qu'en raison de pathologies associees non evidentes. Un autre facteur pourrait jouer un role essentiel dans la variabilite des resultats de la litterature a savoir l'heterogeneite genetique des populations etudiees mais ce facteur est pour l'instant difficile a analyser chez l'homme. La souris, mammifere dont la genetique a ete particulierement bien etudiee est l'espece de choix pour mettre a l'epreuve cette hypothese ; nous avons donc quantifie une population de neurones facilement identifiables, les cellules de purkinje du cervelet, chez des mutants neurologiques de la souris pouvant offrir des modeles d'etude du vieillissement neurologique normal. En effet certains mutants neurologiques de la souris tels que staggerer, reeler, pcd (purkinje celle degeneration) presentent a l'etat homozygote des troubles locomoteurs visibles associes a des pertes neuronales massives dans la sphere olivo-cerebelleuse. Par exemple, chez le mutant homozygote staggerer (sg/sg), 60 a 90 % des cellules de purkinje (cp) sont absentes a un mois post-natal, cette perte s'associant a une atrophie macroscopiquement visible du cervelet et a la degenerescence des afferences de ces neurones. Il a ete montre recemment dans notre laboratoire, que l'heterozygote staggerer (+/sg), qui apparait cliniquement sain en apparence et dont le cervelet semble qualitativement normal, presentait cependant une perte de cp se developpant progressivement avec l'age pour atteindre 30 % chez l'animal de 12 mois. Ce resultat a suggere a ses auteurs que le gene staggerer pouvait constituer a l'etat heterozygote un gene de suscept ibilite au vieillissement neurologique normal du cervelet et cette hypothese a ete a l'origine du present travail. Dans un premier temps nous avons analyse l'evolution du nombre des cps chez le +/sg au dela de 12 mois, c'est a dire au cours du vieillissement proprement dit. Notre deuxieme objectif a ete de voir si l'hypothese emise pour le gene staggerer avait une valeur plus generale a savoir si d'autres genes pouvaient etre des genes de susceptibilite pour le vieillissement du cervelet. Nous avons donc etudie un autre exemple de mutant a l'etat heterozygote, le reeler, qui est lui aussi cliniquement sain en apparence. Le nombre des cps a ete estime che des +/sg femelles agees de 13, 18 et 24 mois et des heterozygotes reeler (+/rl) males et femelles de 3, 16 et 26 mois. Dans les deux groupes, les cervelets inclus dans la paraffine ont ete decoupes dans le plan sagittal en coupes seriees. Les cps ont ete comptes toutes les 40 coupes sous un microscope photonique a un grossissment de x1250. Les resultats bruts des comptages cellulaires ont ete corriges selon la methode de hendry. Chez le +/sg de 13 et 18 mois, il y a une diminution significative du nombre de cp (22 a 26 %) par rapport aux temoins (+/+) du meme age. Ce nombre ne change plus chez les +/sg de 13 et 18 mois alors qu'il diminue chez les temoins de 24 mois de maniere identique a celle des +/sg de 13 et 18 mois. Comme les animaux +/+ de la lignee c57bl/6j, les +/+ de la lignee balb/c (temoins des reelers) presentent une perte de cp qui apparait entre 16 et 26 mois et touche environ un quart de la population des cps chez les males. Toujours chez les males, les +/rl presentent un deficit de 16 % du nombre de cp des 3 mois qui atteint 24 % a 16 mois. Chez les femelles en revanche, il n'y a aucune perte de cp significative avec l'age aussi bien chez les sauvages que chez les heterozygotes. Ces resultats confirment donc l'hypothese que le gene staggerer provoque a l'etat heterozygote un vieillissement precoce du cervelet et que cette vulnerabilite des cps se retrouve aussi dans un autre exemple, l'heterozygote reeler. Dans la troisieme partie de notre travail, nous nous sommes demande si les effets de telles mutations se limitaient a la disparition d'un certain pourcentage de cp ou si elles entrainaient egalement des phenomenes involutifs au niveau des cps qui n'etaient pas affectees par le processus de mort neuronale. Nous avons donc recherche des anomalies de la morphologie des cellules de purkinje survivantes chez des heterozygotes staggerer et leur evolution en fonction de l'age. Pour cela nous avons compare la morphologie des arbres dendritiques des cps d'animaux de 4, 12 et 22 mois de +/sg et de +/+ grace a une methode semi-quantitative qui permet d'examiner un grand nombre de cellules en tenant compte de 9 parametres morphologiques decrivant l'arbre dendritique. Il apparait que la mutation staggerer entraine des 4 mois, une involution dendritique tant en largeur qu'en hauteur qui s'ag

In this project, the performance aspects of a new early generation 1310 nm Sampled-Grating Distributed Bragg Reflector (SG-DBR) semiconductor laser are investigated. SG-DBR lasers are ideal for Source Swept Optical Coherence Tomography (SS-OCT), a Fourier-Domain based approach for OCT, necessitating a tunable wavelength source. Three internal sections control the frequency output for tuning, along with two amplifiers for amplitude control. These O-band SG-DBR devices are now being produced in research quantities. SG-DBR lasers have been produced at 1550 and 1600 nm for some times. Fundamental questions regarding the performance of the 1310 nm devices must be quantified. Standard metrics including the laser linewidth, amplitude modulation and frequency modulation responses are characterized. The intrinsic electrical parasitics of the laser diode segments and packaging are also investigated. In addition, testing fixture including a Thermal Electric Cooler (TEC) controller is for the characterization task. Measurements of these key metrics are essential to the enhancement of future devices, aiding in the optimization of more mature products.

Full textAbstract:
We grow AB₂ random hyperbranched polymer structures in different ways and using different simulation methods. In particular we use a method of ad hoc construction of the connectivity matrix and the bond fluctuation model on a 3D lattice. We show that hyperbranched polymers split into two universality classes depending on the growth process. For a “slow growth” (SG) process where monomers are added sequentially to an existing molecule which strictly avoids cluster–cluster aggregation the resulting structures share all characteristic features with regular dendrimers. For a “quick growth” (QG) process which allows for cluster–cluster aggregation we obtain structures which can be identified as random fractals. Without excluded volume interactions the SG model displays a logarithmic growth of the radius of gyration with respect to the degree of polymerization while the QG model displays a power law behavior with an exponent of 1/4. By analyzing the spectral properties of the connectivity matrix we confirm the behavior of dendritic structures for the SG model and the corresponding fractal properties in the QG case. A mean field model is developed which explains the extension of the hyperbranched polymers in an athermal solvent for both cases. While the radius of gyration of the QG model shows a power-law behavior with the exponent value close to 4/5, the corresponding result for the SG model is a mixed logarithmic–power-law behavior. These different behaviors are confirmed by simulations using the bond fluctuation model. Our studies indicate that random sequential growth according to our SG model can be an alternative to the synthesis of perfect dendrimers.

Full textAbstract:
Motion artefacts due to cardiac and respiratory motion present a daily challenge in cardiac Magnetic Resonance Imaging (MRI), and many different motion correction procedures are used in clinical routine imaging. To reduce motion artefacts further, patients are required to hold their breath during parts of the data acquisition, which is physically straining – especially when done repetitively. Self-Gating (SG) is a method that extracts cardiac and respiratory motion information from the MRI data in the form of signals, called SG signals, and uses them to divide the data into the specific cardiac and respiratory phases it was acquired from. This method both avoids motion artefacts and allow for free-breathing acquisition. This project’s goal was to find a method for extracting cardiac and respiratory SG signals from MRI data. The data was acquired with a golden angle radial acquisition method for 3-dimensional (3D) scans. Extraction of the raw signal was tested for both raw k-space data and high temporal resolution image series, where the images were reconstructed using a sliding window reconstruction. Filters were then applied to isolate the cardiac and respiratory information, to create separate cardiac and respiratory SG signals. Thereafter trigger points marking the beginning of the cardiac and respiratory cycles were generated. The trigger points were compared against ECG and respiratory trigger points provided by the MR scanner. The conclusion was that the SG signals based on k-space data was functional on the scans from the evaluated subjects and the most effective choice of the two options, but image based SG signals may prove to be functional after further studies.Rörelseartefakter på grund av hjärt- och respirationsrörelser är idag vardagliga utmaningar inom magnetresonanstomografi (MR) av hjärtat, och många olika metoder används för att eliminera rörelseartefakterna. Patienterna behöver dessutom hålla andan under delar av dataupptagningen, vilket är fysiskt ansträngande – speciellt när det sker upprepade gånger. Self-Gating (SG) är en metod som extraherar information hjärt- och respirationsrytm från MR-datan i form av signaler, kallade SG signaler, och använder dem för att dela in datan i de specifika hjärt- respektive respirationsfaser som var när datan upptogs. Denna metod både undviker rörelseartefakter och tillåter fri andning under dataupptagningen. Målet med det här projektet var att hitta en metod för att extrahera SG signaler för hjärt- och respirationsrytm från MR-data. Datan samlades in med en golden angle radial-upptagning för 3- dimensionella (3D) scanningar. Extraheringen av den råa signalen testades på både rå k-space data och på bildserier av 3D-bilder med hög tidsupplösning, där bilderna var rekonstruerade med en sliding window rekonstruktion. Därefter applicerades filter för att isolera hjärt- och respirationsinformationen, för att få separata SG signaler med endast hjärt- respektive respirationsrytmer. Till slut genererades triggerpunkter för att markera början av hjärt- respektive respirationscyklerna. Dessa jämfördes med triggerpunkter uppmätta med EKG och andningskudde i magnetkameran. Slutsatsen för projektet var att SG signalerna som baserades på k-space data var funktionell för de scanningar som testades och det mest effektiva alternativet, men SG signalerna som baserades på bilder kan visa sig fungera efter mer studier.

Full textAbstract:
An antinomy is a contradiction between a principle and its opposite, where there is a
compelling case for accepting both. This thesis adopts the antinomy of local-state
government in Australia as its central conceptual theme, describing it with the following
defensible, but contradictory principles that:¶
· Australian local governments are statutory agencies of Australias state
governments, with no power or authority beyond that which is ascribed to them by
the states (the outside-in principle); and¶
· Local governments in Australia are independent agencies whose authority and
interests transcend their regulatory powers by nature of their attachment to their
local area (the inside-out principle).¶
The central conceptual theme of the antinomy of local-state government shapes the
overall thesis, as well as providing the focus for its introduction and conclusion. The thesis
induces elements of the antinomy and structures much of its discussion around these key
issues. It does not try to prove or resolve the antinomy. Instead the thesis uses the concept to
explore and develop its second complex theme - the practical and applied experience of
Australian local governments (LGs) as they attempt to deliver beneficial environmental
outcomes. The great bulk of the substantive work presented in the thesis focuses on
descriptions and analyses of LGs environmental work and the contexts within which they
do it. The thesis contends that the local-state antinomy underpins many problems facing
Australian LGs as they attempt to deliver beneficial environmental outcomes.
Four research questions are addressed. They are:¶
· How can Australian LG capacity to deliver beneficial environmental outcomes be
understood?¶
· Within this capacity, what are the environmental outcomes now being achieved by
Australian LGs?¶
· How can Australian local government extend its capacity to deliver beneficial
environmental outcomes? And¶
· What are the implications of the local-state antinomy on Australian LG capacity to
deliver beneficial environmental outcomes?¶
This thesis reviews literature on Australian LG, LG environmental work, and the
methods that are appropriate in investigating these questions. The overall thesis uses
scientific, grounded theory and action research methods and draws on ideas from symbolic
interactionism. Parts of the thesis also use environmental risk assessment, gap analysis
techniques, case study and comparative analysis. The goal of generating grounded theories
led to a strong focus on the development and exploration of analytical categories and the
relationships between them. One such category summarises the relationship between LG
and state government (SG), whereby LGs are identified as the inside sphere of government,
while the SG is one of several outside spheres. Environmental efforts that impact between
the spheres are described in relation to their source and impact, using this terminology, so
that inside-out initiatives are driven by LGs but impact more broadly, and outside-in
initiatives are driven by states but impact on local areas.¶
Two extensive studies are presented, each stemming primarily from one side of the
local-state antinomy. The first is a quantitative, statewide study of local (and state)
government implementation of the Queensland Environmental Protection Act. That process
is considered a predominantly outside-in environmental initiative, in that LG interest and
authority for that work stem directly from a SG statute. For simplicity, this is referred to as
an outside-in study. That study involved the development and application of the
Comparative Environmental Risk Assessment Method, that enabled the assessment of the
environmental and other outcomes from the Queensland legislation.¶
The outside-in study is complimented by comparative case studies that mostly
reflect inside-out environmental initiatives as they are defined and described by LGs.
Again, this required the development of innovative research methods, specifically a
comparative case study method. 34 case studies gathered from different types of LGs across
Australia are presented, each representing an attempt by LG to deliver beneficial
environmental outcomes.¶
In answer to the research questions, LG capacity to deliver environmental outcomes
can be understood when the antinomy is examined through the research methods and
analytical categories developed and presented here. LGs are delivering significant beneficial
environmental outcomes, both as agents of SGs and through their own initiatives.
Improving LG capacity to deliver environmental outcomes primarily requires a respect for
LG perspectives, and for LG priorities, which inherently include a focus on their own local
areas. State governments can build effective partnerships between the spheres and enhance
LG environmental capacity by recognising and supporting LGs own priorities, while
assisting their engagement with broader strategic objectives.

Full textAbstract:
Currently, in the period of Poststructualism literature is widely approached as a cultural and social phenomenon and the aims of literary studies as the illuminating of social codes, ideology etc. embedded in literature. This study evaluates the contribution of specific critics working within the so-called "New paradigm". The concept "New paradigm" is used as an umbrella term covering a number of distinct developments, referring to literature as a system of literary "actions" rather than as a canon of books. In recent years several Afrikaans critics have embraced or adapted current theories in the domains of Deconstruction, Ideology Criticism, Literary, Sociology, Recepticm Aesthetics, Semiotics and Feminism. This study explores and evaluates the application of such theoretical paradigms to their work in the field of practical criticism. This study also explores the relationship between current theories of literature and their antecedents. The notion of current literary theory and practice not only as a broadening of scope and content of the notion of the "literary" but on the other hand as a liberation of theory and practice from an over-deterministic thrust (i.e. the approach of literature as no more than a set of social documents) is also evaluated in this study. A twofold aim of this study can thus be defined: a. to determine the extent to which the shift from the "old" to "new" theories was made necessary by the developing literary and social scene; b. to examine the links beween theory and practice in the work of specific, key figures in Afrikaans. Is it possible for theory and practice to be separated? Is there an important consistence in the relationship between the two in the work of the figures chosen?

Full textAbstract:
This thesis deals with issues around the implementation of an AMM (Automated Meter Management) system within the Czech electricity distribution system. The theoretical section of the thesis provides a historical context and looks at the development of the electricity sector. The thesis then goes on to discuss issues regarding the competitiveness of distribution companies in terms of IT/ICT use. This section defines the elements of the Smart Grid concept, in particular the AMM system. The chapters dealing with the conditions for implementing the system in the Czech Republic and pilot projects abroad make up the major sources for the practical section. The goal of the practical section is to come up with a project aim for the AMM system implementation trial project in Prague. The proposed project aim is divided into a number of separate tasks whose results are obtained using a detailed analysis of available sources and the conclusions of the theoretical part of the thesis. The thesis's main benefit is in forming a basis for the AMM implementation trial project in PREdistribuce, Inc. distribution networks and providing a comprehensive overview of the development and current state of the electricity sector.

Full textAbstract:
Atualmente, a Leucemia Linfocítica Crônica (LLC) pode ser dividida em dois grupos: um com mutações somáticas no gene da região variável da cadeia pesada da imunoglobulina (MIgVH) e outro sem mutações (NMIgVH). Alguns estudos mostraram que a expressão de CD38 na superfície das células B de LLC pode estar correlacionada com o estado mutacional do gene VHIg, entretanto, esses controversos. Estudos recentes mostraram que a expressão da proteína tirosina quinase Zap-70 está melhor associada com o estado mutacional do gene IgVH. O objetivo deste estudo foi avaliar a expressão de Zap-70 e CD38, por citometria de fluxo, nas células CD19+ de pacientes com LLC e correlacioná-los com o estádio clínico (EC), sobrevida livre de tratamento (SLT) e sobrevida global (SG). A expressão de Zap-70 e CD38 foi avaliada, em 144 de pacientes com LLC classificados nos estádios clínicos A, B e C de acordo com os critérios de Binet: 59 (41%) do EC-A, 38 (26%) do EC-B e 47 (33%) do EC-C. Foi observada menor positividade para Zap-70 e CD38 nos pacientes do EC-A do que nos EC-B e C. Quando avaliada a SLT nos pacientes do EC-A, os casos Zap-70+ assim como os CD38+ apresentaram menor SLT. A média de SG dos pacientes Zap-70+ e CD38+ foi menor quando comparado com os Zap-70- e CD38- entretanto quando correlacionada com o EC não foi observada diferença estatisticamente significante entre a expressão desses marcadores e o EC-A, B ou C. Pela analise combinada de CD38 e Zap-70, dividimos os pacientes em dois grupos (Zap-70-/CD38- e Zap-70+ ou CD38+). Observamos que a expressão positiva desses dois marcadores estava associada ao EC, uma vez que a grande maioria dos pacientes dos estádios B (74%) e C (66%) expressam Zap-70 ou CD38. Entretanto, os pacientes do EC-A, Zap-70+ ou CD38+, apresentaram SG menor quando comparado com os Zap-70-/CD38-. Essa diferença não foi observada nos pacientes do EC-B e do EC-C. Também foi observada menor SLT nos pacientes no EC-A, Zap-70+ ou CD38+. Esses resultados sugerem que análise combinada de Zap-70 e CD38 podem ser empregadas na avaliação dos pacientes do EC-A para se acompanhar a evolução clinica desse grupo de pacientes. Porém, estudos adicionais devem ser realizados para se validar a utilização clínica desses marcadores.Actually, chronic lymphocytic leukemia (CLL) can be divided in two subsets: one with somatically mutated immunoglobulin heavy-chain variable-region genes (MIgVH) and other with unmutated sequences. (UMIgVH). Some studies have shown that CD38 expression in CLL cells are correlated with IgVH mutational status. However, the value of CD38 as surrogate IgVH mutational status is controversial. Recent studies, have found that Zap-70 protein tyrosine kinase expression is strongly associated with the mutational status IgVH. The aim of this study was to evaluate the Zap-70 and CD38 expression, for flow cytometry, in CD19+ LLC cells and correlate with the Binets staging system, treatment-free survival (TFS) and a overall survival (OS). Zap-70 and CD38 was evaluated, in 144 CLL patients that was classified in A, B and C Binets staging system: 59 (41%) in stage A, 38 (26%) in B and 47 (33%) in C. We observed low Zap-70 and CD38 expression in stage A patients than in stage B and C cases. When we analyzed the TFS in stage A patients Zap-70+ and CD38+ patients showed shorter TFS than Zap-70- and CD38-. Then we observed that the OS of Zap-70+ and CD38+ patients was, also, shorter than Zap-70- and CD38- cases. However, statistical differences was not found when Zap-70 and CD38 expression was correlated with stage A, B or C Binets staging system. To understand the associated Zap-70 and CD38 expression, we divided the CLL patients in two subgroups (Zap-70-/CD38 - and Zap-70+ or CD38+). We observed that CD38+ or Zap-70+ was associated Binets staging system, once most of stage B (74%) and C (66%) patients are Zap-70+ or CD38+. However, stage A patients, Zap-70+ or CD38+, showed shorter OS than Zap-70-/CD38-. These differences were not observed in stage B and C patients. Shorter TFS was also observed in the Zap-70+ or CD38+ stage A patients. These results suggest that combined analysis of Zap-70 and CD38 can be used to evaluate stage A patients to observe the clinical evolution of the disease. Nevertheless, other studies must be carried to confirm the clinical use of these markers.
