Abstract (sommario):

Uppsatsen undersöker om antropologiskt kunskap kan implementeras i Logical Framework Approach (LFA) –metoden för att förbättra den. LFA är en projektplaneringsmetod som bland annat används inom utvecklingsprojekt. Olika publiceringar om LFA har studerats för att få fram för- och motargument. Vidare har antropologiska publiceringar om hur antropologi kan användas inom utveckling- och biståndsprojekt legat till grund för att analysera LFA, och se om och isåfall var antropologisk kunskap kan användas för att förbättra den. Resultatet presenteras i form redovisning på var metoden får kritik samt hur antropologisk kunskap kan bidra till förbättring i det specifika området.
The thesis seeks to examine whether anthropological knowledge can improve the Logical Framework Approach (LFA). LFA is a widespread project planning method that is used in development projects. Various publications about LFA have been studied to identify arguments in favor of, and against the method. Furthermore, anthropological publications on how anthropology can be used in development and aid projects forms the foundations for analyzing the LFA. This is performed to see where anthropological knowledge can be applied to improve it. The result is presented by focusing on the criticism to discover how anthropology can contribute to improving the methods in the areas of concern.

Abstract (sommario):

Le cancer de l'ovaire (OvCa) est le cancer le plus mortel parmi les cancers féminins. Il est souvent diagnostiqué tardivement ou mal diagnostiqué, ce qui le rend difficile à traiter. Les options de traitement incluent la chirurgie ou la chimiothérapie, toutefois la résistance à la chimiothérapie est un problème majeur. Il est donc urgent de trouver de nouvelles cibles et de développer de nouvelles stratégies pour surmonter cette résistance.Dans ce contexte le protéome fantôme est une source potentiellement riche de biomarqueurs. Le protéome fantôme, ou protéome alternatif, est composé de protéines traduites à partir de cadres de lecture ouverts alternatifs (AltORFs). Ces AltORFs proviennent de différents codons START issus de différente région de l'ARNm, tels qu'un décalage de cadre de lecture (+1, +2) dans la séquence codante de l'ADN (CDS), dans le 5'-UTR, 3'-UTR et éventuellement de la traduction d'ARN non codants (ncRNA).Les études sur les protéines alternatives (AltProts) sont souvent complexes et nécessite des études biomoléculaires coûteuses. Cependant, leurs fonctions peuvent être déduites en identifiant leurs partenaires d'interaction, la détection des interactions protéine-protéine (PPI) entre AltProts et protéines de référence (RefProts) peut aider à identifier leur fonction. La stratégie de pontage chimique (crosslink) combiné à la spectrométrie de masse (XL-MS) est un outil approprié à cet objectif. De plus, les outils bioinformatiques qui relient les informations fonctionnelles des RefProt et les analyses d'ontologie génique (GO) permettent la visualisation des voies de signalisation et le regroupement des RefProts en fonction de leur processus biologique, de leur fonction moléculaire ou de leur localisation cellulaire, et ainsi y placer certaine AltProt.Dans ce travail, nous avons développé une méthodologie combinant XL-MS et le fractionnement subcellulaire. L'étape de fractionnement subcellulaire nous a permis de réduire la complexité des échantillons analysés par chromatographie liquide et spectrométrie de masse (LC-HRMS/MS). Pour évaluer la validité des interactions, nous avons réalisé une modélisation moléculaire des structures 3D des AltProts, suivie d'une prédiction informatique de l'interaction et de mesure des distances de pontages identifiés expérimentalement. L'analyse a révélé des rôles d'AltProts dans les fonctions et les processus biologiques tel que la réparation de l'ADN ou encore la présentation d'antigène.La protéogénomique a été utilisée pour générer des bases de données protéiques personnalisées à partir des données de séquençage ARN afin d'étudier les protéomes de deux lignées cellulaires de cancer de l'ovaire (PEO-4 et SKOV-3) en comparaison avec une lignée cellulaire ovarienne normale (T1074). L'expression différentielle de plusieurs protéines a ainsi été identifiée entre les lignées cellulaires cancéreuses et normales, avec une association aux voies de signalisation connues pour le cancer. Des PPI ont également été identifiées dans les lignées cellulaires cancéreuses en utilisant la méthodologie XL-MS.Ce travail met en évidence le potentiel de l'approche protéogénomique pour découvrir de nouveaux aspects de la biologie du cancer de l'ovaire. Il nous permet d'identifier des protéines et des variants auparavant inconnus qui peuvent avoir une signification fonctionnelle. L'utilisation de bases de données protéiques personnalisées et de l'approche de réticulation a mis en lumière le "protéome fantôme", une vision du protéome restée inexplorée jusqu'à présent
Ovarian cancer (OvCa) has the highest mortality rate among female reproductive cancers worldwide. OvCa is often referred to as a stealth killer because it is commonly diagnosed late or misdiagnosed. Once diagnosed, OvCa treatment options include surgery or chemotherapy. However, chemotherapy resistance is a significant obstacle. Therefore, there is an urgent need to identify new targets and develop novel therapeutic strategies to overcome therapy resistance.In this context the ghost proteome is a potentially rich source of biomarkers. The ghost proteome, also known as the alternative proteome, consists of proteins translated from alternative open reading frames (AltORFs). These AltORFs originate from different start codons within mRNA molecules, such as the coding DNA sequence (CDS) in frameshifts (+1, +2), the 5'-UTR, 3'-UTR, and possible translation products from non-coding RNAs (ncRNA).Studies on alternative proteins (AltProts) are often limited due to their case-by-case occurrence and complexity. Obtaining functional protein information for AltProts requires complex and costly biomolecular studies. However, their functions can be inferred by profiling their interaction partners, known as "guilty by association" approaches. Indeed, assessing AltProts' protein-protein interactions (PPIs) with reference proteins (RefProts) can help identify their function and set them as research targets. Since there is a lack of antibodies against AltProts, crosslinking mass spectrometry (XL-MS) is an appropriate tool for this task. Additionally, bioinformatic tools that link protein functional information through networks and gene ontology (GO) analysis are also powerful. These tools enable the visualization of signaling pathways and the grouping of RefProts based on their biological process, molecular function, or cellular localization, thus enhancing our understanding of cellular mechanisms.In this work, we developed a methodology that combines XL-MS and subcellular fractionation. The key step of subcellular fractionation allowed us to reduce the complexity of the samples analyzed by liquid chromatography tandem mass spectrometry (LC-MS/MS). To assess the validity of crosslinked interactions, we performed molecular modeling of the 3D structures of the AltProts, followed by docking studies and measurement of the corresponding crosslink distances. Network analysis indicated potential roles for AltProts in biological functions and processes. The advantages of this workflow include non-targeted AltProt identification and subcellular identification.Additionally, a proteogenomic analysis was performed to investigate the proteomes of two ovarian cancer cell lines (PEO-4 and SKOV-3 cells) in comparison to a normal ovarian epithelial cell line (T1074 cell). Using RNA-seq data, customized protein databases for each cell line were generated. Differential expression of several proteins, including AltProts, was identified between the cancer and normal cell lines. The expression of some RefProts and their transcripts were associated with cancer-related pathways. Moreover, the XL-MS methodology described above was used to identify PPIs in the cancerous cell lines.This work highlights the significant potential of proteogenomics in uncovering new aspects of ovarian cancer biology. It enables us to identify previously unknown proteins and variants that may have functional significance. The use of customized protein databases and the crosslinking approach have shed light on the "ghost proteome," an area that has remained unexplored until now

Abstract (sommario):

O presente trabalho propõe sistemas para eliminar o efluente líquido (lixiviado) de um aterro sanitário a partir da combustão do efluente gasoso (biogás) gerado no mesmo local, caracterizando a integração energética dos dois efluentes. As gerações de biogás e lixiviado são referentes ao aterro de Guajuviras e são estimadas usando o modelo de IPCC, 2006 e o modelo de balanço hídrico respetivamente, estimando também suas incertezas de geração. Os resultados foram obtidos para a fase de operação e posteriormente de fechamento de um aterro real, com uma incerteza estimada de 50%. A integração energética dos efluentes é primeiramente verificada para situações de máxima eficiência por meio de balanços de massa e energia. Em sequencia, cinco propostas conceituais de sistemas são apresentadas, tendo em comum a completa eliminação do lixiviado a partir da energia do biogás. Os sistemas Combustor-Evaporador (CE) e Incinerador-Evaporador (IE) tem como produto apenas a evaporação do lixiviado, e consomem cerca de 30% do biogás disponível no aterro. Os sistemas Motor-Evaporador (ME), Combustor-Motor-Evaporador (CME) e Incinerador-Motor-Evaporador (IME) são montados com a finalidade de aproveitar o excedente de biogás, mantendo sempre a evaporação completa do lixiviado. O desempenho dos sistemas propostos é avaliado por meio de indicadores técnico-ambientais e financeiros ao longo de um período de vinte anos, e sua importância é ordenada usando elementos da análise hierárquica de processos (AHP). Todos os sistemas propostos indicam ser viáveis, destacando-se aqueles que produzem energia elétrica, que se mostraram mais atraentes do ponto de vista técnico-ambiental, porém com investimentos específicos altos. Os sistemas que promovem a eliminação do lixiviado e produzem eletricidade com o excedente de biogás (CME e IME) são os mais viáveis financeiramente, com payback de 7 e 8 anos, VPL na media de US $4.790.00 e TIR de 39% aproximadamente. A AHP indica que os sistemas baseados em cogeração têm pesos similares, variando só em 3% ao serem avaliados num viés ambiental. Da mesma forma, o cenário de viés financeiro apresentou uma pequena diferença entre os sistemas CME, IME e CE.
The present work proposes systems to carry out the thermal decommissioning of the liquid effluent (leachate) from a sanitary landfill through the combustion of the gas effluent (biogas) produced in the same place, characterizing the energy integration of the two effluents. The biogas and leachate productions refer to the Guajuviras landfill and are estimated using the IPCC model, 2006, and the water balance model respectively, their production uncertainties are also estimated. The results are obtained for the operation phase and afterwards for a former real landfill, with an estimated uncertainty of 50%. The energy integration of effluents is first verified for situations of maximum efficiency through mass and energy balances. In the sequence, five conceptual proposals of systems are presented, having in common the complete reduction of the leachate from the biogas energy. The simplest CE and CI systems have only the leachate evaporation, and consume about 30% of the biogas available in the landfill. The ME, CME and IME systems are set up to take advantage of the biogas surplus, always maintaining complete evaporation of the leachate. The performance of the proposed systems is evaluated through technical-environmental (PEB and PEL) and financial indicators (IES, NPV, TIR and PB) over a period of twenty years, and their importance is ordered using the Analytic Hierarchy Process (AHP). All proposed systems indicate that they are feasible, especially those that produce electricity, which have been more attractive from an environmental and technical point of view, but with high specific investments (IES). The systems that promote leachate abatement and produce electricity with biogas surplus (CME and EMI) are the most financially viable, with paybacks of 7 and 8 years, NPV average of US $ 4,790.00 and IRR of approximately 39%. The AHP indicates that the cogeneration-based systems have similar weights, varying only by 3% when evaluated in an environmental bias. Likewise, the financial bias scenario presented a small difference between the CME, EMI and EC systems.

Abstract (sommario):

PONTIFÍCIA UNIVERSIDADE CATÓLICA DO RIO DE JANEIRO
Nesta dissertação, propomos uma metodologia para seleção de dados em modelos de Aprendizado por Quantização Vetorial, referenciado amplamente na literatura pela sigla em inglês LVQ. Treinar um modelo (ajuste dentro-daamostra) com um subconjunto selecionado a partir do conjunto de dados disponíveis para o aprendizado pode trazer grandes benefícios no resultado de generalização (fora-da-amostra). Neste sentido, é muito importante realizar uma busca para selecionar dados que, além de serem representativos de suas distribuições originais, não sejam ruído (no sentido definido ao longo desta dissertação). O método proposto procura encontrar os pontos relevantes do conjunto de entrada, tendo como base a correlação do erro de cada ponto com o erro do restante da distribuição. Procura-se, em geral, eliminar considerável parte do ruído mantendo os pontos que são relevantes para o ajuste do modelo (aprendizado). Assim, especificamente em LVQ, a atualização dos protótipos durante o aprendizado é realizada com um subconjunto do conjunto de treinamento originalmente disponível. Experimentos numéricos foram realizados com dados simulados e reais, e os resultados obtidos foram muito interessantes, mostrando claramente a potencialidade do método proposto.
In this dissertation, we consider a methodology for selection of data in models of Learning Vector Quantization (LVQ). The generalization can be improved by using a subgroup selected from the available data set. We search the original distribution to select relevant data that aren't noise. The search aims at relevant points in the training set based on the correlation between the error of each point and the average of error of the remaining data. In general, it is desired to eliminate a considerable part of the noise, keeping the points that are relevant for the learning model. Thus, specifically in LVQ, the method updates the prototypes with a subgroup of the originally available training set. Numerical experiments have been done with simulated and real data. The results were very interesting and clearly indicated the potential of the method.

Abstract (sommario):

Differentiable functions with a locally flat surface (LFS) have been recently introduced and studied in convex optimization. Here we extend this motion in two directions: to non-smooth convex and smooth generalized convex functions. An important feature of these functions is that the Karush-Kuhn-Tucker condition is both necessary and sufficient for optimality. Then we use the properties of linear LFS functions and basic point-to-set topology to study the "inverse" programming problem. In this problem, a feasible, but nonoptimal, point is made optimal by stable perturbations of the parameters. The results are applied to a case study in optimal production planning.

Abstract (sommario):

The central issue in this thesis is configurationality, which has broadly been defined in terms of a division of the world's languages based on their core syntactic structure. Specifically, languages are traditionally divided into so-called configurational and non-configurational languages. Configurational languages are assumed to be languages with many restrictions on word order, and non-configurational languages are assumed to be languages with very few or no word order restrictions. Many linguists posit a strict division between the two different types of languages. In this thesis I propose a non-derivational approach to configurationality, and I discuss in detail three posited characteristics of non-configurational languages (in comparison to configurational languages): free word order, discontinuous expressions and subject-object asymmetries in binding. I propose a four-way classification of languages instead of a two-way one, based on constraints on annotations on phrase structure nodes, both for argument functions and for information structural roles (such as topic and focus). I propose that this four-way distinction is what underlies configurationality. I show that discontinuous expressions and potentially subject-object symmetries follow from the nature of languages that have traditionally been classified as non-configurational. For my analysis I employ Lexical Functional Grammar (LFG), a non-derivational framework which is particularly well-suited to account for languages in which grammatical functions are not tied to specific phrase structural positions, due to its parallel architecture. This characteristic of LFG enables me to provide a straightforward classification of languages, by the ability to separate the influence of grammatical functions and information structural roles on word order and phrase structural configuration.

Abstract (sommario):

Att attrahera, behålla och utveckla rätt kompetens är någonting alla företag behöver uppmärksamma och kontinuerligt arbeta med för att uppnå. Genom att företag uppvisar att de är attraktiva arbetsgivare via ett gott rykte och en gripande introduktion för nyanställda kan de locka och bibehålla kvalificerade medarbetare. I denna studie undersöks hur Luftfartsverket (LFV) arbetar med elevhanteringen och hur detta kan kopplas till generella teorier och modeller anpassat för processen. I examensarbetet används främst enkät i form av ett frågeformulär med flersvarsalternativ, för att samla information kring vilka brister som upplevs inom organisationen. Ett flertal olika kvalitets och ledningsverktyg användes för att granska den insamlade empirin. Träddiagram användes för att bryta ned ett centralt problem på olika nivåer, utifrån de underliggande orsakerna till de upplevda bristerna. Slutsatsen för studien landar i ett antal förbättringsförslag i LFVs elevhanteringsprocess, framförallt i första skedet i utbildningen till flygledare. Små förändringar som kan leda till att LFV kan stärka sin position som en attraktiv arbetsgivare.
Attracting, retaining and developing the right skills is something every company needs to pay attention to and continuously work on. By showing companies that they are attractive employers through a good reputation and a poignant introduction for new employees, they can attract and retain qualified employees. This study examines how the Swedish Civil Aviation Administration Luftfartsverket (LFV) works with student management and how this can be linked to general theories and models adapted to the process. In this study, a survey has been done with multiple-answer options, in order to gather information about what deficiencies are experienced within the organization. A few quality and management tools were used to review the empirical data collected. Tree diagrams have been used to break down a central problem at various levels, based on the underlying causes of the perceived deficiencies. The conclusion of the study includes a number of improvement suggestions in LFV's student management process, especially in the first phase of the training for air traffic controllers. Small changes that can lead to LFV strengthening its position as an attractive employer.

Abstract (sommario):

This thesis aims to present a color segmentation approach for traffic sign recognition based on LVQ neural networks. The RGB images were converted into HSV color space, and segmented using LVQ depending on the hue and saturation values of each pixel in the HSV color space. LVQ neural network was used to segment red, blue and yellow colors on the road and traffic signs to detect and recognize them. LVQ was effectively applied to 536 sampled images taken from different countries in different conditions with 89% accuracy and the execution time of each image among 31 images was calculated in between 0.726sec to 0.844sec. The method was tested in different environmental conditions and LVQ showed its capacity to reasonably segment color despite remarkable illumination differences. The results showed high robustness.

Abstract (sommario):

We undertook a detailed analysis of population spike rate and LFP power in the Zebra finch auditory system. Utilizing the full range of Zebra finch vocalizations and dual-hemisphere multielectrode recordings from auditory neurons, we used encoder models to show how intuitive acoustic features such as amplitude, spectral shape and pitch drive the spike rate of individual neurons and LFP power on electrodes. Using ensemble decoding approaches, we show that these acoustic features can be successfully decoded from the population spike rate vector and the power spectra of the multielectrode LFP with comparable performance. In addition we found that adding pairwise spike synchrony to the spike rate decoder boosts performance above that of the population spike rate alone, or LFP power spectra. We also found that decoder performance grows quickly with the addition of more neurons, but there is notable redundancy in the population code. Finally, we demonstrate that LFP power on an electrode can be well predicted by population spike rate and spike synchrony. High frequency LFP power (80-190Hz) integrates neural activity spatially over a distance of up to 250 microns, while low frequency LFP power (0-30Hz) can integrate neural activity originating up to 800 microns away from the recording electrode.

To understand how an auditory system processes complex sounds, it is essential to understand how the temporal envelope of sounds, i.e. the time-varying amplitude, is encoded by neural activity. We studied the temporal envelope of Zebra finch vocalizations, and show that it exhibits modulations in the 0-30Hz range, similar to human speech. We then built linear filter models to predict 0-30Hz LFP activity from the temporal envelopes of vocalizations, achieving surprisingly high performance for electrodes near thalamorecipient areas of Zebra finch auditory cortex. We then show that there are two spatially-distinct subnetworks that resonate at different frequency bands, one subnetwork that resonates around 19Hz, and another subnetwork that resonates at 14Hz. These two subnetworks are present in every anatomical region. Finally we show that we can improve predictive performance with recurrent neural network models.

Abstract (sommario):

This thesis deals with the meaning of agriculture in the country area and its effect on the development of the rural areas. My goal is to evaluate the actual realization of resources, which are spent on the support of farmers, who practice in areas with less favourable conditions. This is performed on a regional analysis of the number of handed and accepted requests and on the amount of the land usage in disadvantaged areas with the result that my thesis will concentrate on the evaluation of a regional differentiation. This diploma work will deal with the issue of what kind of the Czech agricultural disadvantaged areas happen to use the financial resources in terms of LFA, and what are the main factors of such differentiation in the relation with the aims of this support. The theoretical part of this thesis targets on the country development and the meaning of agriculture in the country area. It describes methods and approaches of determination of the rural area and less-favoured areas. It also characterizes the Rural Development policy in Czech Republic. The analytical part of this work contains a regional payment analysis (in the concept of the rural area) for a natural disadvantage provided in the mountain areas, and payments provided in other less-favoured areas (LFA) in the programming period 2007-2013 in the Czech Republic. For this regional analysis there are used data especially from the implementation organ SZIF, data from the Agricultural Accounting Data Network FADN, and finally data from the Annual Report of the Rural Development Program. Such data are interpreted on the basis of the method of cartographical projection. Farther, this thesis tries to find out if the aim of such action is realized. On account of the performed analysis, my thesis summarizes acquired findings and draws consecutive conclusions from the realization of support.

Abstract (sommario):

Mestrado em Engenharia do ambiente
Tendo em vista a reutilização de águas residuais industriais, foi desenvolvida uma tecnologia denominada Liquid Filtration Technology destinada a desinfectar e filtrar um efluente passível de reutilização. As variáveis de processo consideradas no que concerne a este trabalho, basearam-se em parâmetros de qualidade da água e estudos de viabilidade económica. Para o efeito o equipamento foi instalado em dois locais distintos, em termos de características do efluente e relativamente ao tipo de tratamento de águas residuais aplicado na indústria, com o intuito de estudar e avaliar a sua aplicabilidade. No âmbito do trabalho foi ainda desenvolvido e aplicado um conceito de viabilidade económica à avaliação da tecnologia, com consideração aos consumos de água, tarifários e custos do equipamento e instalação. Os resultados obtidos permitem retirar as seguintes considerações: (a) A qualidade do efluente após passagem pelo LFT tem valores mais significativos numa Estação de Lavagem de Automóveis, que num Matadouro de Aves; (b) A viabilidade económica do LFT varia consoante os consumos de água requeridos. Assim sendo, a implementação na Estação de Lavagens não se torna viável ao contrário do Matadouro, que suporta um valor de VAL muito significativo; (c) A ineficiência operacional do LFT verificada no matadouro, encontra-se relacionada com a rápida colmatação do filtro, devido às características dos sólidos em suspensão; (d) A possibilidade de acoplar um equipamento extra de filtração, a fim de evitar problemas técnicos foi estudada, nomeadamente no caso do efluente do Matadouro; (e) A tecnologia desenvolvida possui condições adequadas para aplicação na reutilização de efluentes industriais, nomeadamente em lavagens auto com elevada eficiência.
Considering the reuse of industrial wastewater has been developed a technology called Liquid Filtration Technology designed to filter and disinfect an effluent capable of reuse. The process variables considered in regard to this work, based on parameters of water quality and economic feasibility studies. For this purpose the equipment was installed in two locations, both in terms of effluent treatment as compared to the subject in order to study and evaluate its applicability. As part of the work has already been developed and applied a concept of economic viability assessment of technology, with regards to water consumption, prices and equipment costs and installation. The results allow to draw the following considerations: a) The quality of the effluent after passage through the LFT is more significant in the Station Car Wash, which in a poultry slaughterhouse; b) The economic viability of the LFT depends on the consumption of water required. Therefore, the implementation of Washing Station does not become viable in contrast to Slaughterhouse, which supports a significant amount of VAL; c) The operational inefficiency observed in the treatment of the treated effluent from the slaughterhouse is associated with rapid filter clogging due to the characteristics of the suspended solids; d) The possibility of engaging an extra filtration equipment in order to avoid technical problems have been studied, particularly in the case of wastewater of slaughterhouse; e) The technology developed has conditions suitable for application in industrial wastewater reuse, including car washes, with high efficiencies.

Abstract (sommario):

Opportunities to use synthetic aperture radar (SAR) in scientific studies and military operations are expanding with the development of small SAR systems that can be operated on small unmanned air vehicles (UAV)s. While the nimble nature of small UAVs make them an attractive platform for many reasons, small UAVs are also more prone to deviate from a linear course due autopilot errors and external forces such as turbulence and wind. Thus, motion compensation and improved processing algorithms are required to properly focus the SAR images. The work of this dissertation overcomes some of the challenges and addresses some of the opportunities of operating SAR on small UAVs. Several contributions to SAR backprojection processing for UAV SARs are developed including: 1. The derivation of a novel SAR backprojection algorithm that accounts for motion during the pulse that is appropriate for narrow or ultra-wide-band SAR. 2. A compensation method for SAR backprojection to enable radiometrically accurate image processing. 3. The design and implementation of a real-time backprojection processor on a commercially available GPU that takes advantage of the GPU texture cache. 4. A new autofocus method that improves the image focus by estimating motion measurement errors in three dimensions, correcting for both amplitude and phase errors caused by inaccurate motion parameters. 5. A generalization of factorized backprojection, which we call the Dually Factorized Backprojection method, that factorizes the correlation integral in both slow-time and fast-time in order to efficiently account for general motion during the transmit of an LFM-CW pulse. Much of this work was conducted in support of the Characterization of Arctic Sea Ice Experiment (CASIE), and the appendices provide substantial contributions for this project as well, including: 1. My work in designing and implementing the digital receiver and controller board for the microASAR which was used for CASIE. 2. A description of how the GPU backprojection was used to improved the CASIE imagery. 3. A description of a sample SAR data set from CASIE provided to the public to promote further SAR research.

Introduction: Peru is a country that is undergoing a process of democratic transformation. Local and international development agencies are established in Peru in order to support this process. In the last decade, there has been an encouragement for these agencies to use strategic management in their project work. The Logical Framework Approach (LFA) is an objective-oriented approach that has become widely employed for the planning, implementation and evaluation of development projects. The so called “vertical logic” of the LFA, rests on the assumption that project stakeholders can predetermine and agree on how certain activities will lead to the accomplishment of a hierarchy of formally stated goals.

Purpose: The purpose of this thesis is to analyze the applicability of the vertical logic of LFA on development projects in Peru.

Theoretical framework: The theoretical framework of this paper is based on theories and arguments raised for and against Management By Objectives (MBO) from which the LFA originates. In addition, the special features of the development sector are discussed in regard to this rational goal approach.

Method: This paper has been carried out as a Minor Field Study (MFS) in Peru where representatives of local as well as international development agencies have been interviewed.

Empirical findings and Analysis: This paper highlights the special characteristics of development work in Peru. Projects are typically large with abstract, complex goals and multiple stakeholders. In addition, they are carried out in an environment typified by significant instability and change. These characteristics potentially make some of the features inherent in the vertical logic of LFA, such as strict planning and goal congruency, unrealistic. This potentially limits its usefulness as a strategic management tool.

Abstract (sommario):

This work was undertaken to characterise the interaction of the leukocyterestricted integrin LFA-1 (CD1la/CD18) with its ligands. LFA-1 function is critical for an immune response and, for example, allows leukocyte binding and transmigration across the endothelium, antigen presentation and cytotoxic T lymphocyte-mediated killing. The ligands for LFA-1 are the Intercellular Adhesion Molecules (ICAMs), with ICAM-1, ICAM-2 and ICAM-3 being the best characterised. The binding sites on ICAM-1 and ICAM-3 for LFA-1 were investigated with the use of antibodies and mutated proteins. The following regions were found to have a role in binding LFA-1: the CFG face of ICAM-3 domain 1; domain 2 of ICAM-1; a residue in domain 1 of ICAM-1 that is mutated at high frequency in African populations and is associated with susceptibility to cerebral malaria. Binding of Mg2+ or Mn 2+ to the extracellular region of LFA-1 and intracellular signalling can both stimulate LFA-1 to adhere to ICAM-1, but by different processes. The former mechanism induces a high affinity form of LFA-1, which was shown to be achieved by an inter-domain movement involving the I domain of the LFA-1 a subunit. This is the first physical evidence for a conformational change occurring in an integrin upon activation. The mechanism by which intracellular signalling activates LFA-1 was demonstrated to involve calpaindependent clustering of LFA-1 in the membrane, thus increasing the avidity of LFA-1 for ICAM-1. Leukocyte Adhesion Deficiency-1 and Glanzmann's Thrombasthenia are genetic disorders in which mutations in the integrin genes result in absence of expression or expression of a non-functional integrin. The defects in function of leukocytes from a patient with clinical features of both disorders were studied. The results suggest that the patient has a novel form of integrin dysfunction in which integrins are expressed at normal levels, can be induced to bind their ligands by mechanisms which increase the affinity of interaction, but cannot be stimulated to bind ligand by intracellular signalling pathways.

Abstract (sommario):

This study provides description and analysis of some verbal complementation patterns in Egyptian Colloquial Arabic (ECA), namely the Auxiliary /kaan/, Causative /xalla/, phasal verbs and modals. Each verb is represented by a set of sentences extracted from a 5 million word corpus of ECA online texts that was built for the purpose of the current study using the Sketch Engine tool. These verbal complements are described and analysed within the principles of LFG syntactic theory, and represented in a grammar fragment implemented using the XLE tool. The analysis shows that both tense and aspect can be expressed verbs in ECA, where in simple tense forms the verb carries tense only, while in compound tense, the main predicate marks tense and occupies I while the following lexical verb marks grammatical aspect and occupies V. The bi- prefix marks present tense on verbs in I and imperfect aspect on verbs in V, as well as a HAB/PROG feature. The bare Imperfective verb form is treated as a non-finite verb in ECA, where it can not occupy I and is marked by VFORM=BARE. All of the verbal constructions analysed are bi-clausal structures, however, they show differences regarding the kind of control relation. Functional control was attested in constructions where the main predicate is the auxiliary /kaan/, the causative verb /xalla/, phasal verbs, as well as non-inflecting modals. Anaphoric control was attested only with inflecting modals, with the modal /yi2dar/ ‘able’ showing a case of obligatory anaphoric control. This is, to my knowledge, the first study which attempts to develop a grammar for ECA using the XLE platform. It provides an insight over the issues correlated with developing this grammar, which could be a step towards including ECA into the ParGram project in order to develop broad coverage grammars for a bigger number of languages.

Abstract (sommario):

Educational researchers, practitioners and policymakers agree that quality of leadership and learning influence the quality of education. In the context of Ghanaian basic schools, previous research has shown that the Leadership for Learning (LfL) framework, an educational theory and practice, has improved the leadership capacities of education stakeholders as well as the quality of teaching and learning. However, the processes which lead to such improvements have not yet been studied. This study aimed to contribute to research on LfL by analysing the processes that accounted for the successful incorporation of the LfL principles. This in-depth case study was conducted in two successful LfL schools in the Central Region of Ghana. It engaged multiple stakeholders and gathered data through semi-structured interviews, focus group discussions, observations, and document analysis. Intra- and inter-case analyses were conducted to understand each case in its own terms as well as to identify areas of convergence and divergence between them. The findings reveal that despite the ubiquity of household poverty, youth unemployment, and paucity of infrastructure, stakeholders recreated structures, reoriented attitudes, developed self-efficacy, and deployed creativity. It has been found that stakeholders were able to come to a shared and contextualised understanding of the LfL principles. This engendered collaboration, co-ownership of the leading, teaching and learning activities, and their successful institutional absorption. Put differently, the successful incorporation of the LfL principles was driven by four practices: the stakeholders understood the principles based on their contextual realities; believed in their understanding; taught what they believed in; and practised what they taught. These findings are of practical relevance for policymakers and practitioners. Policymakers need to appreciate the importance of context in understanding and incorporating policy initiatives. Practitioners need to reorient their attitudes and practice, collaborate, form communal beliefs, and recognise, appreciate and harness their internal human capital to succeed. Further research is needed to understand the impact of communication technology - television soap operas, mobile phones and social media on leading, teaching and learning.

Abstract (sommario):

Les systèmes à paramètres variants restent un défi pour la synthèse de lois de commande à cause des grands domaines de fonctionnement et des variations associées du comportement du système. Une axe de recherche s'est orientée vers les approches de séquencement de gains dont la majorité est basée sur la synthèse d'un ensemble de correcteurs indépendants pour divers points de fonctionnement. Ces correcteurs sont ensuite interpolés après leur synthèse. Dans ce mémoire, la transformation fractionnelle linéaire LFT ou forme standard d'un système est utilisée pour la synthèse directe d'un correcteur auto-séquencé, c. A. D. Paramétré de manière explicite évitant ainsi la procédure parfois difficile d'interpolation. La méthode de synthèse proposée est basée sur la commande modale. Plusieurs algorithmes pour l'implémentation en temps réel sont introduites et les critères de faisabilité et de convergence associés sont développés. Ils sont aussi comparés par rapport à leur temps de calcul en ligne. L'implémentation pratique est finalement illustrée avec deux applications aérospatiales : le contrôle d'une formation de satellites et l'asservissement en tangage d'un avion de combat générique.

Abstract (sommario):

Factorized backprojection is a processing algorithm for reconstructing images from data collected by synthetic aperture radar (SAR) systems. Factorized backprojection requires less computation than conventional time-domain backprojection with little loss in accuracy for straight-line motion. However, its implementation is not as straightforward as direct backprojection. Further, implementing an azimuth window has been difficult in previous versions of factorized backprojection. This thesis provides a new, easily parallelizable formulation of factorized backprojection designed for both pulsed and linearly frequency modulated continuous wave (LFM-CW) stripmap SAR data. A method of easily implementing an azimuth window as part of the factorized backprojection algorithm is introduced. The approximations made in factorized backprojection are investigated and a detailed analysis of the corresponding errors is provided. We compare the performance of windowed factorized backprojection to direct backprojection for simulated and actual SAR data.

Abstract (sommario):

This thesis aims to address some aspects of the Low Frequency Instrument (LFI) on board the PLANCK satellite. As for any CMB experiment a great attention has to be devoted to all the possible systematic effects. Previous experiences in CMB experiments have in fact demonstrated that the more and the larger are systematic effects which contaminate the data and which have to be scrubbed in the data analysis, the less robust the final results will be. It is therefore of great importance, for not degrading the nominal angular resolution and sensitivity per resolution element, to carefully address and quantify all potential systematic effects. Through accurate and realistic simulations of PLANCK-LFI observations we study how LFI performances are affected by some of these systematic effects and how to control and further reduce these effects. This thesis is organized as follows. We give a brief overview of the origin of microwave sky fluctuations, including CMB anisotropy, foreground contaminations originated within our Galaxy (synchrotron, free-free and dust emission) and extra-galactic foregrounds (Sunyaev-Zel'dovich effect and point sources fluctuations). Since accurate simulations are needed, they must include complete and realistic simulated microwave sky at the various observing frequencies. Unfortunately our present knowledge of foreground emissions (both galactic and extra-galactic) is far from complete and approximations have to be made. All these problems are discussed in Chapter 2. A presentation of the PLANCK mission and its scientific capabilities is reported in Chapter 3: §3.2 reports on the selected orbit and scanning strategy; §3.3 describes the adopted telescope configuration and actual focal plane arrangement; §3.4 briefly outlines the LFI instrument and §3.5 reports LFI scientific capabilities. An introduction to the systematic effects addressed in this thesis is in §3.6 and the Flight Simulator code is presented in §3. 7. . The rest of the work deals with the results from different kinds of PLAN9K-LFI :?imulations. The off-axis position of the LFI instrument, as in the present baseline, results in optical aberrations in the angular response function of the instrument. The effect of these distortions (usually called main-beam distortions since they affect the very central part of the response function) on the nominal angular resolution is addressed in Chapter 4, firstly considering a pure CMB sky, and then a more realistic sky including galactic emission. §4.l uses approximated response functions while "real" optical simulated ones are considered in §4.4. The effective angular resolution is derived and the loss in capabilities of cosmological parameters extraction properly quantified. The angular response function of the LFI instrument at large angles out of the central part is extremely complex and depends not only on the telescope design but also on the whole optical system (shields, supporting structures, focal plane assembly). Signal and signal variations entering at large angles from the true direction of observation may produce errors on CMB measurem~nts. Chapter 5 addresses this issue using a simulated full pattern of the response function and considering signal coming from our Galaxy (§5.1 and §5.2). The level of this contamination and its spatial distribution on the sky are discussed in §5.4. As described in Chapter 2, PLANCK is a spinning space-craft with 1 minute period. Instrumental drifts occurring on time scales less than the spinning period are possible sources of systematic artifacts in final data. In general they produce "stripes" in the final maps. Chapter 6 considers typical instrumental drifts which are mainly due to gain fluctuations in the LFI amplifiers. A de-striping code for removing these artifacts is described in §6.6; its performances and possible residual striping are evaluated in §6. 7. Finally, Chapter 7 overviews simulations results and their implication on the optimization of the PLANCK design.

Abstract (sommario):

The 1st of January this year the state owned Swedish Luftfartsverket changed their name into the shorter name LFV. The shorter LFV is a more modern version in terms of that the name is a proof of that the classic organisation of the state, Luftfartsverket, with this step

breaks through boarders and finds new ways. Plans have existed before but since 2005 when Luftfartsverket lost its assignments from the government and become a state owned business corporation, the plans have intensified. Now, also for all the employees, it is

getting obvious that something is going on in the organisation.

The purpose of this paper is to see how this newly made change of name and logotype have been recieved and how it has effect the strategic choosen respondents within the organisation LFV. These choosen respondents have thorough knowledge of the organisation of LFV. Some of the questions to these respondents were how they reacted

from the change and how have they interpret the changes? Or is there actually no change for them?

Hopefully, the good and valueable values from Luftfartsverket will remain and continue to be connected to the organisation even with the three letters new name.

A conclusion this paper has come up with is that this step is, within this group of respondents, a very small step indeed with not much of visable signs of the name- and logotype change. Nevertheless, all of the strategic choosen respondents are aware of that this is really a longer process and this is just the start of it. Moreover, all of the respondents sees this step as positive for the organisation of LFV.

Statliga Luftfartsverket bytte 1 januari i år namn till det kortare LFV. Det nya namnet är en förkortning av det förra namnet samtidigt som det är ett bevis på en modernisering och ett bevis på att den klassiska statliga organisationen nu bryter gränser. Sedan januari 2005 då Luftfartsverket tappade sina myndighetsuppdrag och blev ett statligt affärsverk istället för myndighet, har planerna på en bolagisering intensifierats. Lösa planer har funnits länge på en förändring inom organisationen. Sedan regeringen tillsatt en flygplatsutredning om LFV:s framtida flygplatsuppdrag samt att nu namnbytet är gjort börjar LFV:s personal också se att något är på gång.

Syftet med den här uppsatsen är att se på hur det nyligen gjorda namn- och logotypbytet har mottagits av några strategiskt utvalda informanter. Dessa informanter har en god insyn i organisationen samtidigt som de alla har olika funktioner och avdelningar. Hur har dessa personer i viktiga ställningar inom organisationen tolkat att namn- och logotypbytet skett och hur har deras dagliga arbete ändrats – om det ens har det?

Med en trebokstavskombination istället för det 15 bokstäver långa ”statliga” namnet tyder mycket på att det kommer att bli lättare att bolagiseras om så blir beslutat. Det statliga och byråkratiskt klingande ”verket” uttalas då inte längre men ändå kan

förhoppningsvis de goda värdena som trygghet och säkerhet stanna kvar med namnet. Anser informanterna att detta steg som tagits är något positivt eller försvinner en trygghet i och med att LFV än så länge är ett okänt begrepp hos gemene man?

En slutsats i denna undersökning är att steget som tagits anses vara ett litet, eller till och med ett mycket litet sådant. Samtidigt är samtliga informanter medvetna om att detta bara är början på en längre process som de ser som positiv för LFV.

Abstract (sommario):

För verksamheter som arbetar processorienterat är det viktigt att kunna mäta och följa upp verksamhetens processer för att få svar på var man står i nuläget och hur framtida mål kan uppnås. Vid mätning av processer måste man dessutom veta vad som ska mätas, varför man gör det och göra det på rätt sätt. Ett sätt att mäta verksamhetens prestation är med Key Performance Indicators (KPI), mätetal som tagits fram för att möta verksamhetens målsättningar. LFV är ett statligt verk som ansvarar för flygtrafiktjänster i Sverige, och det är på avdelningen för Teknikuppdrag som denna studie utspelar sig. LFV har krav på sig från EU att reducera sina kostnader för flygtrafiktjänster med 2,4 % årligen fram till 2019, vilket öppnar upp för effektiviseringsåtgärder som kan bidra till besparingarna. Studien går ut på att kartlägga och ta fram relevanta KPIer för orderprocessen för produkten flygmätning, för att möjliggöra uppföljning av processen. För att finna lämpliga KPIer har en omfattande litteraturstudie genomförts, därtill har intervjuer med representanter från LFV utförts. Studien resulterade i en ny, korrigerad, processkarta för produkten flygmätning, samt i tre stycken KPIer som kan användas för att följa upp processen. Dessa tre KPIer är Ledtid, Leveransprecision och Andel felfria transaktioner. Utöver detta har även processens design uppmätts enligt mätetal speciellt utformade för detta.

A presente tese descreve a elaboraÃÃo de uma gramÃtica da frase do PortuguÃs Brasileiro, desenvolvida no quadro de um modelo teÃrico de sofisticado formalismo computacional, a Lexical Functional Grammar (LFG) e implementada no sistema que constitui o estado da arte em ambiente de processamento sintÃtico profundo no modelo gerativo da LFG, o robusto Xerox Linguistic Environment (XLE). A principal caracterÃstica da gramÃtica Ã que adota o sistema de anotaÃÃo do ParGram e a metodologia convencionada por desenvolvedores de gramÃtica XLE. No fragmento de gramÃtica estÃo modelados diversificados elementos da sintaxe frasal. Em nossa gramÃtica, foram modelados constituintes oracionais como IP e CP, elementos que encabeÃam as sentenÃas do portuguÃs. TambÃm foram modelados determinados aspectos da subcategorizaÃÃo verbal e da estrutura argumental. Dos elementos verbais, nossa gramÃtica contempla alguns casos de complexos verbais constituÃdos de verbos modais e verbos de controle. Os elementos nominais tratados na gramÃtica, de modo central, foram os pronomes expletivos e reflexivos, e os casos de sintagmas nominais e determinantes com pronomes demonstrativos e interrogativos. Os demais aspectos modelados na gramÃtica sÃo os sintagmas preposicionados, cuja complexidade se dÃ na distinÃÃo entre preposiÃÃes semÃnticas e nÃo semÃnticas; os sintagmas adjetivais, cuja projeÃÃo na sentenÃa pode ocorrer a partir de formas adjetivais atributivas, de formas ordinais ou cardinais e na forma de intensificadores; e os sintagmas adverbiais, cuja estrutura interna foi modelada levando-se em consideraÃÃo tanto advÃrbios intransitivos quanto transitivos com complemento PP. A nossa avaliaÃÃo demonstra que das 40 sentenÃas testadas, a nossa gramÃtica atribui, para todas elas, anÃlises consistentes e bem fundamentadas, ao passo que o parser Palavras, o atual estado da arte em processamento sintÃtico profundo do portuguÃs, atribui, a 9 sentenÃas, anÃlises incorretas. Uma outra avaliaÃÃo demonstra que, das 20 sentenÃas agramaticais testadas tanto em nossa gramÃtica, quanto no Palavras, somente 2 receberam anÃlises por parte de nossa gramÃtica, enquanto o Palavras fornece anÃlises para 19 sentenÃas. O trabalho tem, essencialmente, o objetivo de fazer uma descriÃÃo formal e fundamentada de um amplo leque de fenÃmenos do portuguÃs brasileiro, mas, sobretudo, tem o objetivo de contribuir com uma gramÃtica nÃo trivial da frase do portuguÃs no formalismo LFG-XLE, disponibilizando efetivamente um recurso gramatical do portuguÃs voltado para o processamento de linguagem natural.
The present thesis describes the development of a Brazilian Portuguese sentence grammar, developed in the framework of a sophisticated computational formalism, named Lexical Functional Grammar, and implemented on a system that is state of the art in deep parsing environment in LFG generative model, the robust XLE. The main feature of the grammar is that it adopts the ParGram annotation system and the methodology agreed by XLE grammar developers. In the grammar fragment are modeled diverse elements of phrasal syntax. In our grammar were modeled constituents as IP and CP, elements that are head the sentences of the Portuguese. Also were modeled certain aspects of verbal subcategorization and argument structure. In terms of verbal elements, our grammar includes some cases of verbal complex made up of modal verbs and control verbs. The nominal elements treated in grammar, centrally, were the expletives and reflexive pronouns, and cases of nominal and determiners phrases with demonstrative pronouns and interrogative. The other aspects modeled in the grammar are PPs, whose complexity is given the distinction between semantic and nonstandard prepositions; the adjectival phrases, whose projection in the sentence can occur from attributive adjectival forms of ordinal or cardinal forms and as intensifiers; and adverbial phrases, whose internal structure was modeled taking into account both adverbs as intransitive and as transitive, with PP complement. Our evaluation shows that of the 40 tested sentences, our grammar assigns, for all of them, consistent and well-founded analysis, while the parser Palavras, the current state of the art in deep syntactic processing of Portuguese, assigns incorrect analysis for 9 sentences. Another evaluation shows that, of the 20 ungrammatical sentences tested both in our grammar, as in Palavras, only 2 received analysis by our grammar, while the Palavras provides analysis to 19 sentences. The work has essentially the goal of making a formal and grounded description in a broad range of phenomena in Brazilian Portuguese, but mainly aims to collaborate with a not trivial grammar of the sentence in the LFG-XLE formalism, effectively contributing to a grammatical resource turned to the natural language processing.

Abstract (sommario):

Approximations made in the traditional signal model for synthetic aperture radar (SAR) processing cause defocusing of the radar images when the system operates under conditions where the approximations lose validity. This dissertation investigates a number of these approximations and presents algorithmic improvements based on generalizations of the approxmations of the SAR signal model. These improvements result in better focused imagery from SAR systems with varied designs and parameters. Among the advancements presented is the development of a generalized chirp-scaling algorithm and a generalized frequency scaling algorithm to address the problems caused by approximations based on a Taylor series expansion of the SAR signal for both pulsed SAR and linear frequency modulated continuous wave (LFM-CW) SAR systems. These generalized algorithms extend the ability of frequency-domain algorithms to process SAR data from systems with a low frequency, a wide beamwidth, and a large bandwidth. Image formation algorithms are developed that account for the continuous platform motion and compensate for translational position errors due to the continuous non-ideal motion of real-world LFM-CW SAR systems, including a backprojection algorithm that does not rely upon the traditional stop-and-go approximation for platform motion.

Abstract (sommario):

The Standard Model (SM) of particle physics assumes that the couplings between leptons and the electroweak gauge bosons are independent of the lepton flavour up to a correction due to the mass. This property is known as Lepton Flavour Universality (LFU). Ideal laboratories to test the LFU are the b-hadron semileptonic decays which can be studied through the ratios of branching fractions between decays with the τ lepton and the ones with the μ lepton in the final state: R(Hc) =B(Hb → Hcτν)/B(Hb → Hcμν), with Hb and Hc the b−hadron which originates the decay and the c−hadron produced in the decay respectively. Experimental results on LFU tests have been obtained by Belle, BaBar and LHCb collaborations and show tension with the SM prediction of about 3.4σ when considering the combination of the measurement of R(D) and R(D∗). Exploiting the abundance of the b-hadron produced in the LHCb environment and the features of the detector, that allow to reconstruct the b-hadron decay vertex with high precision and to perform particle identification, this thesis documents the preliminary studies for the measurement of R(Ds) using the τ decaying in 3 charged pions. The data sample used for the studies corresponds to an integrated luminosity of 2 fb^{−1} of proton-proton collision events at a centre-of-mass energy of 8 TeV collected by the LHCb experiment in 2012. Given the request of high precision measurements to further test the SM in many other sectors, the LHCb experiment is currently being upgraded to be able to operate at a luminosity of about 2×10^33cm^{−2}s^{−1} from the start of Run3 in 2022. To cope with the challenge of a five-fold increased instantaneous luminosity, and the need to read-out the full LHCb detector at a rate of 40 MHz, the photon detectors and the electronics chain of both the Ring Imaging CHerenkov (RICH) detectors have been replaced. This thesis also describes the quality assurance and test protocols on the new opto-electronics and reports of the commissioning activities.
ITA: Il Modello Standard (MS) della fisica delle particelle elementari assume che l’accoppiamento elettrodebole tra i leptoni e i bosoni di gauge sia indipendente dalla famiglia leptonica a meno di correzioni dovute alla massa. Tale proprietà è conosciuta come Universalità Leptonica (Lepton Flavour Universality o LFU). I decadimenti semileptonici di adroni b sono laboratori ideali per testare la LFU attraverso il confronto tra i rapporti di diramazione dei decadimenti nel cui stato finale sono coinvolti un leptone τ o un leptone μ: R(Hc) = B(Hb → Hcτν)/ B(Hb → Hcμν), dove Hb e Hc sono rispettivamente l’adrone b da cui si origina il decadimento e l’adrone c prodotto nel decadimento. Risultati sperimentali su test di LFU sono stati ottenuti dalle collaborazioni Belle, Babar e LHCb e mostrano tensioni con le predizioni del MS di circa 3.4σ quando si considera la combinazione delle misure di R(D) and R(D∗). Questa tesi, sfruttando l’abbondanza di adroni b prodotti in LHCb e le caratteristiche del rivelatore, documenta gli studi preliminari per la misura di R(Ds) richiedendo nello stato finale un leptone τ che decade in 3 pioni carichi. I dati analizzati per questi studi sono stati raccolti da LHCb nel 2012, sono relativi a collisioni protone protone con energia nel centro di massa pari a 8TeV, e corrispondono ad una luminosità integrata di 2 fb^{−1}. Data la richiesta di misure sempre più precise per testare ulteriormente il MS, l’esperimento LHCb è stato sottoposto ad un upgrade per essere in grado di operare alla luminosità di circa 2×10^33cm^{−2}s^{−1} dall’inizio del Run3 nel 2022. Per fronteggiare la sfida di una luminosità istantanea aumentata di cinque volte rispetto al Run2 e alla necessità di acquisire i dati ad una frequenza di 40 MHz, i rivelatori di fotoni e l’intera catena di elettronica di entrambi i sottorivelatori Ring Imaging CHerenkov sono stati sostituiti. Questa tesi descrive, inoltre, i protocolli di controllo qualità, i test effettuati sulla nuova optoelettronica, e le attività di istallazione e messa in opera dei nuovi sottorivelatori.

Abstract (sommario):

Natural killer (NK) cells and cytotoxic T lymphocytes (CTLs) are effectors of cell-mediated cytotoxicity towards virally infected and tumourigenic cells. The integrin leukocyte function associated antigen-1 (LFA-1) is required for the adhesion of effector cells to their targets. In addition, LFA-1 transduces signals resulting in actin polymerization. We show that in both CTLs and NK cells, LFA-1 ligand binding results in the recruitment of actin, the cytoskeletal adaptor talin, and the activator of actin nucleation Wiskott-Aldrich Syndrome protein (WASP). We used talin-knockout (KO) NK cells to demonstrate that talin is required for LFA-1 mediated adhesion and polarization towards the target cell. This actin polarization is a prerequisite for subsequent steps leading to cytotoxicity, including the translocation of cytotoxic granules. Further analysis of the LFA-1 mediated signaling that leads to actin polymerization shows that talin recruits proteins that catalyze de novo actin formation. Talin forms a complex with vinculin and the actin-nucleator Arp2/3, and talin is required for the movement of these proteins to LFA-1 following LFA-1 binding to ICAM-1. In addition, talin binds the phosphatidylinositol phosphate kinase PIPKIγ and talin is required for the localized production of phosphatidylinositol 4,5 bisphosphate (PIP₂) following LFA-1 ligation. This production of PIP₂ is required for the recruitment of WASP, which in turn activates Arp2/3 to polymerize actin. Thus we have demonstrated a critical role for talin in the actin polarization that is required for cell-mediated cytotoxicity and elucidated the mechanism of LFA-1 mediated actin polymerization.
