Abstract:

SammanfattningTinnitus är idag ett folkhälsoproblem i Sverige som drabbar allt fler. Det finns i dagsläget inget definitivt botemedel men det finns behandlingsmetoder som syftar till att på olika sätt lindra tinnitus. En av dessa metoder är Tinnitus Retraining Therapy (TRT) som grundar sig i den neurofysiologiska modellen. TRT består av två delar; rådgivning och ljudterapi. I ljudterapin tillämpas vanligtvis en ljudstimulator som tillför ett bredbandigt brus på svag nivå i patientens öra.SyftetSyftet med uppsatsen är att redogöra för effekten av behandlingsmetoden Tinnitus Retraining Therapy.MetodMetoden har omfattat granskning av artiklar som sökts via Örebro Universitets databaser samt via relevanta referenslistor i arbeten, böcker och artiklar. Urvalet har innefattat tre steg. Första steget var att välja ut artiklar publicerade i vetenskapliga tidskrifter genom att granska artiklarnas titel. Andra steget var att granska de artiklar som valdes ut i steg ett genom att läsa deras sammanfattningssida för att se om innehållet var relevant för arbetets syfte. Tredje steget var att utförligt läsa de artiklar som valts ut i steg två.Resultat och diskussionResultatet och diskussionen visar att det är svårt att säga huruvida TRT är effektivt. För detta skulle en mer omfattande liknande studie vara nödvändig.

Abstract:

A relevant contribution to sustainable development can be achieved by providing efficient solutions for heating buildings. The use of a heat pump taking heat from the bedrock with the help of a borehole heat exchanger is a common solution in Sweden to accomplish this. In situ measurement of the thermal conductivity of the ground by means of thermal response test is necessary for medium to large size installations to ensure proper sizing of the borehole system. This master thesis was done in cooperation with the department of geo energy at the company Bengt Dahlgren. The aim was to design a new compact thermal response test equipment, test it on a coaxial borehole heat exchanger and evaluate the test results and design a simple business model for using the equipment commercially. The company already had an equipment for thermal response tests, which formed the basis for the new equipment. A literature review was done to gain knowledge on thermal response test equipment, its components and borehole heat exchangers. Also, an evaluation of results from an earlier test of an 800 m deep borehole with a coaxial borehole heat exchanger was made. The project resulted in the construction of a new more compact equipment for thermal response tests with a new, improved heating solution. Two different business models based on renting out the equipment were designed. The equipment was tested on a 200 m deep borehole with a coaxial borehole heat exchanger. The test indicated a thermal conductivity of 2.46 𝑊𝑚∙𝐾 and a borehole resistance of 0.031 m∙KW. En viktig del av en hållbar utveckling är energieffektiva lösningar för uppvärmning av byggnader. En vanlig lösning i Sverige är att använda en värmepump kopplad till en borrhålsvärmeväxlare och utnyttja berggrunden som värmekälla. I vissa fall är det motiverat att testa bergets värmeledningsförmåga med hjälp av ett termiskt responstest för att mer precist kunna dimensionera borrhålen. Denna mastersuppstas gjordes i samarbete med Bengt Dahlgren geoenergi. Arbetet syftade till att designa en kompakt utrustning för termiskt responstest, testa den nya utrustningen på en koaxial borrhållsvärmeväxlare och utvärdera testresultatet samt att designa en enkel affärsmodell för den nya utrustningen. Företaget hade sedan tidigare en utrustning för termiskt responstest, som låg till grund för designen av den nya. En litteraturstudie utfördes för att få mer kunskap om termisk responstestutrustning, dess komponenter och borrhålsvärmeväxlare. Dessutom gjordes en utvärdering av mätresultat från ett tidigare utfört test på ett 800m djupt borrhål med en koaxial borrhålsvärmeväxlare. Arbetet resulterade i en ny kompaktare utrustning för termiskt responstest med en ny smart lösning för uppvärmningen. Två olika affärsmodeller baserade på uthyrning av den nya utrustningen togs fram. Utrustningen testades på ett 200 m djupt borrhål med en koaxial borrhålsvärmeväxlare. Borrhålet visade en termisk värmeledningsförmåga på 2,46 𝑊𝑚∙𝐾 och ett borrhålsmotstånd på 0,031 m∙KW

Magíster en Ciencias de la Ingeniería, Mención Recursos y Medio Ambiente Hídrico Ingeniero Civil El desarrollo de los intercambiadores de calor como sistemas de aprovechamiento de energía geotérmica de muy baja entalpía, ha contribuido de forma significativa a reducir el consumo de energía en la climatización de edificios. Para obtener un buen rendimiento de este tipo de sistemas es necesario realizar un diseño óptimo, lo cual requiere una buena estimación de los parámetros térmicos. El test de respuesta térmica (TRT) es el método actualmente empleado para la determinación de las propiedades térmicas del suelo para el diseño de sistemas geotérmicos de muy baja entalpía tradicionales. Los sistemas de pilotes geotérmicos utilizan los pilotes de fundación requeridos en la construcción de edificios, como intercambiadores de calor con el suelo, al incorporarle un circuito de tuberías en su interior por donde fluye el líquido transportador de calor. Estos sistemas son relativamente nuevos y presentan ciertas diferencias con respecto a sistemas tradicionales, lo que hace necesario estudiar la validez de aplicar pruebas TRT para su diseño. Lo anterior es la motivación del trabajo de esta tesis, en la cual se utilizó un modelo numérico desarrollado en COMSOL Multiphysics® para reproducir TRTs sintéticos en un pilote geotérmico bajo ciertas condiciones ideales. Basado en el análisis de los resultados de las simulaciones numéricas, se concluye que la interpretación de los resultados de TRTs en este tipo de sistemas es complejo, ya que dependen de la relación entre la conductividad térmica del suelo y del concreto, la tasa de la capacidad calorífica volumétrica entre el suelo y el material de relleno, el diámetro del pilote, y el espaciamiento entre tuberías, entre otros factores. Los errores asociados a cualquiera de esos parámetros en la interpretación de dichas pruebas mediante el uso del método tradicional de análisis, que considera una fuente lineal de calor (LHS), pueden ser hasta un 50% de sobrestimación para pruebas de relativa corta duración. Por ejemplo, el análisis de las simulaciones indica que, para un pilote de un metro de diámetro, es necesario realizar pruebas de más de 400 horas para obtener resultados confiables. Además, estos errores pueden ser acumulativos lo que puede aumentar la incertidumbre respecto a la estimación de los parámetros de diseño. Por lo anterior, se recomienda utilizar el conjunto de resultados generados en este estudio para estimar factores de corrección que deben aplicarse al interpretar los resultados de TRT en pilotes geotérmicos. Se espera que de esta forma los resultados presentados en este estudio permitan una correcta interpretación de los resultados de pruebas de terreno de corta duración, con el consiguiente beneficio en términos logísticos y económicos.

Due to power system growth, it is possible that high voltage circuit breakers are not able to interrupt short-circuit currents and to withstand the TRy. This is a study for the reevaluation of 15 kV breaker performances at Companhia Hidroelétrica do São Francisco (CHESF) Angelim Substation. Digital simulations are carried out to compute the TRV parameters and to compare them with the standard ones. Alternatives are proposed to reduce the peaks and rate of rise of TRVs. It is shown that ZnO devices placed across the breaker terminals are very effective in reducing TRV peaks. A forma de onda da tensão entre os terminais de disjuntores, quando da abertura de seus contatos, é definida como a tensão de restabelecirnento e nos seus instantes iniciais como a tensão de restabelecimento transitória (TRT). Considerando a expansão dos sistemas de potência, é possível que disjuntores de alta tensão não estejam mais adequados a interromper correntes de curto-circuito e suportar tensões transitórias. Neste trabalho é apresentado um estudo para a reavaliação dos disjuntores de 15 kV instalados na subestação Angelirn, pertencente a Companhia Hidroelétrica do São Francisco (CHESF). E realizado um estudo para três disjuntores, obtendo formas de onda da TRT através de simulações digitais. E feita uma análise dos parâmetros da TRT, comparando-os com os valores estabelecidos em normas técnicas. Alternativas para a redução do pico e da taxa de crescimento da TRT são propostas. A inserção de dispositivos de ZnO entre os terminais dos disjuntores produz redução significativa no pico da TRT.

Abstract:

The objective of this study is to examine historically the policies of theDirectorate of Documentary Programs (DDP) of the Turkish Radio Television Corporation (TRT). Since there is very little research about particular sphere of the public service broadcasting in Turkey it is aimed to contribute to this area of study. In the course of the study, historical conditions, structural factors, broadcasting policies, the conditions of public broadcasting of a country, and the role of individuals and the research methods applied in media studies were taken into consideration. Furthermore, governmental, military, lawful, economic, cultural policies, and policies emerging from the institutional mechanisms, and practices of individuals are illustrated regarding the different time periods. In this study, documentary research, observation, interview, and internet research were used as data gathering methods. Literature analysis, historical analysis and interpretative analysis were employed as methods of analysis. It is mentioned that the role of individuals in the analysis of media studies is not paid much attention, additionally, especially in Turkey, research conducted about media generally ignores the methods of ethnography, field research and interpretative analysis. In analyzing the policies of DDP, it is asserted that except for the structural effects, individuals/actors have also roles in shaping these policies. Furthermore, to examine the media, particularly television policies, it is maintained that there is a need to carry out analysis at the individual level by the help of conducting field research, applying methods of ethnography, and interpretative analysis in Turkey. Finally, it is claimed that to a large extend DDP have been under the effects of public broadcasting notion of Turkey, and there is a need for improving the institutional policies for the DDP to serve the public interest.

Abstract:

This thesis introduces intercultural broadcasting as an alternative and more accurate term to that of the strongly associated term to propaganda: international broadcasting. It challenges theories of public diplomacy. and public sphere by criticising public diplomacy as a term due to its abandonment of the core element of its process that is the power of ordinary citizens' unity, and provides the Arabs and Muslims as an example of a strong transnational public sphere due to the availability of the elements of unity amongst the roots of their shared values system which shapes their culture. This thesis examines the approaches of DW-TV Arabia and TRT-Etturkiyye in building bridges when targeting Arabic speaking audiences by analysing their dialogical programme content, as well as the overall programme genres. The uniqueness of this study comes from two points: it is the first research done by one of the targeted audience's members of the DW-TV Arabia and second, the TRT-Etturkiyye is relatively new and has changed its policies within the last year. This thesis argues that, before building bridges, with the international world, countries are to build inner bridges with immigrants of the same nationalities as the international targeted groups. For instance, the Arabs and Muslims have lots of values in common that present them as a transnational public sphere; thus, Germany can seize the largest group of its immigrants - who are Muslims as well - to benefit from its public diplomacy efforts worldwide. Also, this thesis records the reactions of both DW - TV Arabia and TRT - Etturkiyye towards the Arab Uprising of 2011, which forced both to create new programmes, invite new Arab guests and adopt new airing schedules. This thesis was built upon original data collected from surveying ninety-one participants, general thematic analysis of four weeks of DW-TV Arabia and TRT-Etturkiyye programmes, and detailed content analysis of the equivalent of twelve hours of episodes for each channel. The content analysis has been divided into two phases: the first was before the Arab Uprising of 2011 and the second afterwards. This thesis attempts to propose an innovative intercultural approach, considering the reality of this era's current international affairs. It outlines how an intercultural Arabic broadcaster targeting other cultural audiences should look.

Abstract:

La conception d'un système géothermique dépend des propriétés thermiques du sous-sol. Ces propriétés sont la conductivité thermique, diffusivité thermique et la capacité thermique. Ces propriétés peuvent varier selon les zones géographiques et sont donc calculées à partir d'un test de réponse thermique. La méthode d'essai conventionnelle est cependant très coûteuse, car elle nécessite la mobilisation d’un équipement lourd. La manipulation de l'équipement sur le terrain est également laborieuse. Les réservoirs d'eau et les canalisations doivent être manipulés avec précaution pour éviter les fuites. La tuyauterie doit être bien isolée afin de minimiser le transfert de chaleur vers l'environnement extérieur. Une nouvelle méthode d'expérimentation alternative qui est plus facile à exécuter, pour conduire les tests de réponse thermique sur le terrain (TRT) in situ, utilise un câble chauffant introduit verticalement dans le puits pour mesurer la température du fluide à différentes profondeurs. Pour évaluer la conductivité thermique du sous-sol le modèle de la ligne source est utilisé en combinaison avec le principe de superposition des courbes durant la période de restitution thermique. L’analyse du test de réponse thermique est aussi réalisée avec un modèle numérique tridimensionnel qui prend en considération l’état hétérogène du sous-sol ainsi que les fluctuations de l’injection de chaleur et de l'épaisseur du tube.

Para tal situação, tem-se como objetivo principal analisar a formação dos novos perfis profissionais, que surgem a partir da criação da educação corporativa no TRT 16ª MA e as implicações para o mundo do trabalho. Desta forma, aborda-se o contexto histórico que passou por grandes mudanças, principalmente no que diz respeito às estratégias que o capital utilizou para superar a crise iniciada em 1970. Dentre as formas estratégicas de recomposição, o capital aponta para dois caminhos: a globalização e a reestruturação produtiva. Nesse aspecto, mostra-se o contexto de mudança no mundo do trabalho e os principais determinantes para o surgimento da educação corporativa no TRT 16ª MA. Ainda, traz-se a proposta pedagógica para a formação e desenvolvimento de competências, sua base legal, juntamente com os desafios encontrados para formação dessas competências no ambiente organizacional. Consecutivamente, faz-se a análise das novas demandas exigidas pelo mundo do trabalho para a formação de um perfil profissional que se adéque à perspectiva da organização. Nesse ponto, mostra-se a perspectiva do trabalhador em relação às formações e, também, sobre a questão da competitividade. Expõem-se, dentro da questão das novas demandas do mundo do trabalho, os principais desafios encontrados pela educação corporativa no TRT, dentre eles cita-se a questão da educação à distância e sua concepção de aprendizagem. Para tanto, definiu-se como referenciais teóricos as contribuições de autores como: Meister (1999), Eboli (2004), Frigotto(2003), Chiavenato (2008), Ramos (2011), Bayma (2004), Leite (2003), Tauille (2001), Harvey (2004), Dupas (1999), Paiva (1991), Coriat(1994), Zarifian (2003), Castells (2010) e Antunes (2009 e 2010). A metodologia utilizada caracterizou-se como uma pesquisa bibliográfica e de campo, com aplicação de entrevistas com servidores do TRT (01 gestor, 01 magistrado, 04 servidores técnicos judiciários). Assim, chegou-se à conclusão, por meio dos resultados obtidos e analisados, de que a educação corporativa no TRT, apesar de gerenciar e desenvolver competências para os servidores da organização tem na sua base as características e os princípios estratégicos do processo de qualificação que atende as demandas para a formação de novos perfis profissionais diretamente relacionados como o processo de reestruturação produtiva.

Abstract:

Dissertação (mestrado)—Universidade de Brasília, Faculdade de Tecnologia, Departamento de Engenharia Civil e Ambiental, 2016. Os sistemas trocadores de calor acoplados ao solo têm sido usados por anos como sistemas de aclimatização de prédios residenciais e comerciais. Estes sistemas foram adaptados para estruturas de fundação com o fim de trocar energia térmica com o solo. Atualmente, estacas de energia são implementadas em muitos países para substituir parte da energia elétrica e outros tipos de fontes de energia. O Brasil é o nono consumidor de energia elétrica em todo o mundo, onde muita dessa energia é utilizada para o uso de acondicionamento climático. Por esta razão pesquisas relacionadas com estacas de energia no Brasil são estimuladas com o fim de reduzir o consumo de energia elétrica. Testes de resposta térmica têm sido realizados em uma estaca de energia instalada no campo experimental da Universidade de São Paulo na região subtropical de São Carlos. Simultaneamente, se realizaram simulações de sistemas de estaca de energia com propriedades térmicas obtidas durante o ensaio para avaliar o desempenho da troca de calor dos sistemas na região. Para a análise numérica, são avaliados os efeitos térmicos devido à variação em propriedades térmicas do solo e concreto, geometria da estaca, vazão, posição do nível freático de água, espessura da tubulação e temperatura média de entrada. Adicionalmente, se determina o espaçamento ótimo entre estacas para permitir o melhor desempenho das estacas. Em este documento se apresentam resultados e análises de modelos simulados no software COMSOL, utilizando os módulos Heat Transfer e Non-Isothermal Pipe Flow, e com eles, obtendo assim a configuração ótima de trabalho. Foi observada a melhora do comportamento térmico da estaca com o acrescimento dos valores em parâmetros geométricos, o número de tubulações e da vazão em condições de fluxo turbulento. Parâmetros como a espessura da tubulação e condutividade térmica do solo e concreto proporcionam aportes energéticos não muito significativos no resultado da troca de calor da estaca estudada. Ground-Coupled Heat Exchanger Systems has been used as acclimatization system for residential and commercial buildings. This system was adapted to pile foundations in order to exchange thermal energy with the ground. Currently, this foundation system has been implemented in many countries to replace an important part of electrical and other sources of energy. Brazil is the ninth largest consumer of electrical energy in the world, and much of this energy is used for air conditioning. For this reason, researchers in Brazil are investigating the use of energy piles in order to reduce the consumption of electricity. Thermal response tests have been carried out on a heat exchanger pile at the geotechnical experimental site of the University of São Paulo in São Carlos city, region of subtropical climate. Simultaneously, using the thermal properties obtained in these tests, numerical analysis has been performed to investigate the heat exchange performance of energy piles installed in this site in São Carlos. For this numerical analysis, the effect of variations due to soil and concrete properties, pile geometry, groundwater level, pipe thickness and the flow rate on the pile thermal response were evaluated. Additionally, is determined the optimal space between piles that allows a better performance of each pile. The current paper presents the results obtained by the analysis models simulated to found an optimal configuration of an energy pile through the software COMSOL, using Heat Transfer and Non-Isothermal Pipe Flow modules. From this work, it was observed that the optimal configuration was obtained for a turbulent flow condition in piles with greater length and diameter. The effects of thickness in pipe, the thermal conductivity of the surrounding soil and concrete were not very influential on the thermal performance of the heat exchanger pile.

Abstract:

Este estudo tem como objetivo central identificar e problematizar os impactos e dilemas do ECA junto à Justiça do Trabalho TRT 12, durante a década de 1990, na cidade de Florianópolis, tendo em vista ser esse o período de implementação do Estatuto. A partir da análise de um corpus documental de 300 ações processuais trabalhistas, obtidas no Arquivo do Serviço de Digitalização e Guarda, buscamos perceber como e se os operadores/as do Direito do Trabalho remetiam-se ao ECA na formulação dos documentos que compunham os autos do Judiciário Trabalhista. Nessas ações, dentre as quais, 299 foram aJuizadas por trabalhadores e trabalhadoras com idade inferior a dezoito anos e uma pelo Ministério Público do Trabalho, nos foi possível verificar como se constituíam as relações de trabalho entre empregadores/as de diferentes setores e empregados/as infantojuvenis, em uma Florianópolis que passava por profundas transformações urbanas com um quadro de aumento demográfico resultante de um significativo processo migratório. A década de 1990, no Brasil, foi marcada por uma aplicação de políticas neoliberais, que teve como consequência o aumento das taxas de trabalho informal, de dessalariamento e de desemprego, provocando uma situação socioeconômica de maior vulnerabilidade, sobretudo, no que tange às famílias pobres. Como decorrência dessa situação, acentuaram-se as taxas de trabalho infantil ilegal e juvenil ilegal e/ou irregular em todo o país, e em especial na cidade de Florianópolis, onde nos foi possível mapear o lugar ocupado pelos contingentes infantojuvenis protagonistas desta história. Os dilemas do ECA quanto ao trabalho infantojuvenil estão relacionados à necessidade que famílias empobrecidas têm de se utilizarem dessa mão de obra para a própria subsistência. Os impactos relativos a esse Estatuto na sociedade brasileira são muitos, como é o caso da Ação Civil Pública, que contando com a atuação conjunta do Ministério Público do Trabalho, da Delegacia Regional do Trabalho, do Conselho Tutelar da Criança e do Adolescente de Florianópolis e do TRT 12 levou à erradicação das atividades de jornaleiro/a e encartadores de jornais, formas de trabalho infantojuvenil que perduraram por muitas décadas na cidade de Florianópolis. Verificamos, por fim, que para a erradicação do trabalho infantil e para a regularização do trabalho juvenil faz-se necessária a efetivação de um conjunto de políticas públicas voltadas à melhoria de renda dessas famílias, para que não dependam dessa força de trabalho, assim como dos demais direitos, educação, saúde, cultura, lazer e etc., reconhecidos à infância e à adolescência. The present thesis has as its goal to identify and discuss the impacts and dilemmas raised by the Brazilian Child and Adolescent Rights Act (ECA) in the sphere of action of the Labor Courts (TRT 12) in the city of Florianopolis (Brazil), during the 1990s, in which context that legislation was introduced. From the analysis of 300 labor lawsuits located in the official Digital Archives of that institution, I seek to understand the means by which the labor law operators made use of and referred to the ECA in order to formulate the documents that based the judiciary processes. In the set of those lawsuits, 299 were filed by workers of under eighteen years old and one by the Labor Public Ministry. By the analysis of the documents is possible to identify how were formed working relationships between employers and young workers in different economic sectors of a town that was passing by deep urban transformations linked to the migration process and the population growth. The 1990s in Brazil was marked by the introduction of neoliberal policies, which led to an increase in informal employment rates, cheap labor and unemployment, causing a social and economic situation of greater vulnerability, especially among poor families. As a result of it occurred the increasing of illegal or irregular child and juvenile labor rates in Florianopolis. This study shows the place occupied by those young workers protagonists of this narrative in the recent social and economic processes of that city. The dilemmas that have been raised since the introduction of ECA are related to the needs ofpoor families, which depend on children and youngslabor fortheir livelihood. There are many impacts of ECA in the Brazilian society, such as the Public Civil Action, which involves joint efforts of the Ministry of Labor, the Regional Labor Office, the Council of Guardianship of Children and Adolescent and the Labor Court (TRT 12), which led to the eradication of the paperboys activities, a form of work that lasted for many decades in Florianopolis. Finally, this thesis demonstrates thatthe eradicationof child labor andthe regularizationof youth work should be a part of a broad set ofpublic policies aimed atimproving the incomeof poor families,so that they do notdepend onthislabor force, as well as children and adolescents must be recognized as holders of rights in terms of education, health, culture, recreation and so on.

Abstract:

La radiothérapie interne vectorisée ou RIV consiste à adresser spécifiquement un isotope radioactif aux tumeurs grâce à un vecteur spécifique. Dans le cas du mélanome, le vecteur utilisé pour la RIV peut être un anticorps ciblant des antigènes de surface ou la mélanine, des analogues peptidiques capables de se fixer sur des récepteurs tumoraux (comme le récepteur à la melanocyte-stimulating hormone) ou des petites molécules se liant à la mélanine (dérivées des benzamides). Ainsi, notre équipe travaille sur cette dernière stratégie depuis 15 avec la molécule phare [ 131 I]ICF01012. De nombreuses études précliniques ont permis un essai clinique de phase I, MELRIV1, qui est ouvert depuis juillet 2019 (NCT03784625). En parallèle de cet essai,nous avons poursuivi la caractérisation préclinique des effets d’[ 131 I]ICF01012 en monothérapie et en association avec les traitements actuels du mélanome, dans la perspective d’essais cliniques de phase II.Ce travail est divisé en deux axes :1) étudier les effets de la RIV par [ 131 I]ICF01012 sur les principaux mécanismes impliqués dans la progression du mélanome : la dissémination métastatique et la pseudo-transition épithélio-mésenchymateuse, l’activation de la voie des MAPK et l’échappement à la réponse immunitaire antitumorale ;2) évaluer des combinaisons d’[ 131 I]ICF01012 avec les traitements actuels du mélanome métastatique : thérapies ciblant la voie des MAPK et inhibiteurs de checkpoints immunitaires.Pour le premier axe, grâce à un modèle de sphéroïdes, nous avons montré que la RIVpar [ 131 I]ICF01012 modifiait l’expression de gènes et de protéines impliquées dans la pTEM et pouvait donc permettre de limiter la dissémination métastatique. Ces modifications s’accompagnaient également d’une différentiation des cellules de mélanome, associée à l’induction d’une pigmentation. Nous avons également mis en évidence, dans les sphéroïdes BRAF et NRAS mutés, une activation de la voie des MAPK dans les suites de la RIV, qui peut traduire l’installation d’une radiorésistance. L’association de la RIV aux inhibiteurs de MEK dans le modèle de sphéroïdes a démontré la possibilité d’utiliser ces molécules pour radiosensibiliser les cellules de mélanome présentant une activation constitutionnelle de la voie des MAPK avec une augmentation majeure de l’apoptose. Nous avons également montré l’impact d’[ 131 I]ICF01012 sur la dissémination métastatique par voie hématogène, notamment, par ciblage des cellules circulantes, et par voie lymphatique, par diminution du nombre de métastases ganglionnaires. Nous avons également montré in vitro et in vivo la très grande radiosensibilité de la lignée NRAS 1007, qui présente une mutation Q61K du gène NRAS.Pour la deuxième partie, le modèle murin syngénique B16F10 a permis de montrer que les effets immunitaires de la RIV s’appuient sur le déclenchement d’une mort immunogénique,permettant la mise en place d’une réponse immunitaire adaptative et le recrutement de cellules T cytotoxiques au sein de la tumeur. Cependant, la mise en place de cette réponse s’accompagnait aussi du recrutement de lymphocytes T régulateurs, qui peuvent contribuer à l’échappement de la tumeur à la réponse immunitaire. L’association de la RIV aux inhibiteurs de checkpoints immunitaires a permis de montrer que la mise en place de la tolérance immunologique était un phénomène majeur induit [ 131 I]ICF01012 alors que l’épuisement des cellules T semblait plus anecdotique. De plus, nous avons montré dans notre modèle, que la réduction de la tolérance immunologique par un anticorps anti-CTLA-4 conduisait à un accroissement de l’épuisement des cellules T. Nous avons également obtenu des résultats très prometteurs en termes de survie, notamment pour l’association de la RIV avec un anticorps anti-CTLA-4, qui conduisait à un allongement significatif de la survie par rapport aux monothérapies,sans augmentation de la toxicité. (...) Targeted radionuclide therapy (TRT) is a therapeutic strategy which consists in specificallyaddressing a radionuclide to tumor by targeting, through a specific vector. For melanoma TRT,the vector could be an antibody targeting surface antigens or melanin, a peptidomimetic ableto bind to receptors (i.e. the melanocyte-stimulating hormone receptor) or some smallmolecules which specifically bind to melanin (benzamides). Our research is focused on the latterclass with the lead molecule [ 131 I]ICF01012 developed in our unit for 15 years. Promisingpreclinical studies have resulted in a phase I clinical trial, MELRIV1, opened since July 2019(NCT03784625). In line with this trial, we pursued the preclinical characterization of [ 131 I]ICF01012effects in monotherapy and in combination with current melanoma treatments.We then defined two main axes:1) [ 131 I]ICF01012 impact on main mechanisms involved in melanomagenesis: metastaticdissemination and epithelial-mesenchymal-like transition, activation of the MAPK pathway andescape from anti-tumor immune response;2) [ 131 I]ICF01012 combination with current treatments: potential benefit assessmentIn the first axis, we developed a spheroid model and showed that [ 131 I]ICF01012 alteredthe expression of genes and proteins involved in pTEM and could therefore limit metastaticdissemination. These modifications brought also melanoma cell differentiation and induction ofpigmentation. Importantly, we showed the efficiency of [ 131 I]ICF01012 on metastaticdissemination by hematogenous route, targeting circulating cancer cells, and by lymphaticroute, decreasing number of lymph node metastases. We also demonstrated in vitro and in vivothe very high radiosensitivity of Q61K mutated NRAS 1007 cells. We also demonstrated, in themutated BRAF and NRAS spheroids, an activation of the MAPK pathway following TRT irradiation,traducing radioresistance appearance.For the second part, combination of TRT with MEK inhibitors in the spheroid modeldemonstrated the possibility of using these molecules to radiosensitize melanoma cells withconstitutional activation of the MAPK pathway. This radiosensitization lead to a major increase ofapoptosis. In the B16F10 syngeneic mouse model, we showed that TRT immune effects rely onimmunogenic cell death initiation, leading to adaptive immune response and cytotoxic T cellrecruitment. These mechanisms come with recruitment of regulatory T-cells which can contributeto tumor escape from immune response. Combination of TRT with immune checkpoint inhibitorsevidenced that immunological tolerance was a major induced mechanism following[ 131 I]ICF01012 irradiation while T-cell exhaustion appeared as a minor phenomenon. In addition,we were able to show that the reduction of immunological tolerance by an anti-CTLA-4antibody increases T-cell exhaustion. Furthermore, TRT combined with immune checkpointinhibitors, especially with anti-CTLA-4, led to a significant increase of survival compared tomonotherapies, with no increase of toxicity.Taken together, these results confirm the potential role of TRT using [ 131 I]ICF01012 in themanagement of metastatic melanoma. Notably, association with inhibitors of checkpointsinhibitors appears to be very promising for further clinical trials following the Phase I trial of[ 131 I]ICF01012

Abstract:

This thesis looks at how involved implementers of the Teaching Recovery Techniques-project in Uppsala, Sweden have experienced the project. Teaching Recovery Techniques is originally a group-based intervention created for use in disaster areas. This intervention has the aim to give self-help to unaccompanied refugee minors with post-traumatic stress symptoms in Uppsala and two neighbouring municipalities, by using non-psychiatric personnel to teach stress-mitigation. This is a pilot project as Teaching Recovery techniques have never been used in this type of setting before. To investigate the opinions of the involved personnel, qualitative interviews with roughly half of the group leader have been made. These have been analysed using manifest content analysis. The thesis found that while many are happy with the project, it has required unexpectedly high workload as well as suffered from unclear responsibility delegations and lacking communication, primarily in the start of the project. However, due to strong motivation from involved implementers and adaptability from employers, these issues have been overcome to a great degree. Lesson for further TrT-projects targeting unaccompanied minors should put extra effort in planning and defining the roles of involved actors as well as include arenas for horizontal communication between group leaders. Denna uppsats undersöker hur personal involverad i Teaching Recovery Techniques-projektet i Uppsala, Sverige har upplevt att arbete inom projektet. Teaching Recovery Techniques är ursprungligen en grupp-baserad intervention ämnad att användas i katastrofzoner. Syftet med Teaching Recovery Techniques är att ge hjälp till själv-hjälp till ensamkommande flyktingbarn med posttraumatisk stress symptom i Uppsala kommun samt två grannkommuner. Projektets mål är att använda icke-psykiatrisk personal för att lära ut stresshantering. Detta är ett pilotprojekt då metoden inte använts i denna kontext tidigare. För att undersöka personalens åsikter så har kvalitativa intervjuer utförts med hälften av gruppledarna. Dessa har sedan analyserats utifrån manifest innehållsanalys. Denna uppsats visar att även om många är nöjda med projektet, så har det krävts mycket mer arbetstid än väntat samt att det har varit oklar ansvarsfördelning och kommunikation, framförallt i början av projektet. Dock har stark motivation från personal och hög flexibilitet från arbetsgivare, motverkat dessa problem i de flesta fall. Lärdomar till framtida likande projekt för ensamkommande flyktingbarn är att ha ett ökat fokus på planeringsstadiet, samt att definiera roller och ansvar bättre från start. Det rekommenderas även att skapa forum för horisontell kommunikation mellan gruppledare.

Reflection of judicial decisions in social life has not been approached with the importance the matter requires, especially where the relations resulting from the conflicts between capital and work are concerned. The purpose of this paper is to draw the attention to decisions made by the Labour Federal High Court and the Regional Labour Court in Maranhão relative to precarious labour in Brazil, with emphasis on aspects such as contracting out, flexibilization of rights, poor health and hygienic conditions of workers and degrading work, which, sometimes, reaches the boundaries of slavery. The judicial posture adopted by the Labour Justice seeks to strike a balance between protecting the worker and preserving the company. Considering that the Judicial Power is part of the capitalist State, accomplishing that goal is questionable. In despite of that, the Labour Justice has developed and established itself as the branch of the Judiciary closest to social issues, not only when it plays the role of a mediator between individual and collective conflicts, but also when it, through its judges, prevents the fraud to the employment protection legislation. It can be concluded that the decisions of the Judicial Power based on constitutional principles and rules of employment protection and dignity of human being contribute to the effectiviness of labour rights. O Judiciário trabalhista e a precarização do trabalho. Estudo sobre a atuação da justiça do trabalho e a relação de suas decisões com a precarização do trabalho no Brasil, considerando que esse é o ramo especializado para dirimir conflitos decorrentes das relações oriundas entre capital e trabalho. A presente pesquisa utiliza a jurisprudência do Tribunal Superior do Trabalho e do Tribunal Regional do Trabalho do Maranhão nos temas de terceirização, flexibilização de direitos, condições de saúde e higiene do trabalhador e formas degradantes de trabalho, inclusive em condição análoga à de escravo. Conclui-se que a postura jurídica adotada pela Justiça do Trabalho oscila entre a proteção ao trabalhador e a preservação da empresa, buscando um ponto de equilíbrio cujo alcance é questionável, uma vez que o Judiciário é poder integrante do Estado capitalista. A Justiça do Trabalho cresceu e se firmou como o ramo do Judiciário mais ligado às questões sociais, ao estabelecer uma prática mediadora nos conflitos individuais e coletivos, e impedir ou reprimir com suas decisões, a fraude à legislação trabalhista. Percebe-se, por fim, que as decisões do Poder Judiciário, exaradas em sentenças ou acórdãos, podem contribuir para a efetividade dos direitos trabalhistas, quanto mais estejam respaldadas nas regras e princípios constitucionais da proteção ao trabalho e da dignidade da pessoa humana.

Abstract:

[ES] Uno de los mayores retos para el mercado de bombas de calor geotérmicas es el alto coste asociado a la perforación de los intercambiadores de calor geotérmicos. Conseguir unos intercambiadores de calor geotérmicos más eficientes reduciría dicho coste, ya que sería necesaria una menor longitud de intercambiador para obtener las mismas temperaturas de trabajo en él (misma eficiencia de la bomba de calor). La eficiencia térmica de un intercambiador de calor geotérmico está caracterizada por su resistencia térmica. Dicha resistencia térmica depende de una serie de elementos entre los que se encuentran: propiedades y caudal del fluido que recorre el intercambiador de calor, diámetro de la perforación geotérmica, geometría y materiales de la tubería del intercambiador de calor y las propiedades del material de relleno de la perforación (grouting). Cuanto mayor sea la resistencia térmica del intercambiador de calor, menor será el calor transferido entre el fluido caloportador y el terreno, traduciéndose en una necesidad mayor de longitud de intercambiador enterrado. Por lo tanto, es necesario una reducción de este parámetro al mínimo posible. En consecuencia, el objetivo principal de esta tesis doctoral consiste en, a partir de un modelo analítico comprensivo de cuantificación del impacto de los parámetros anteriores, realizar un estudio detallado para analizar su influencia combinada en la resistencia térmica del intercambiador geotérmico, pero también examinando dicho efecto en otros planos, como costes económicos de ejecución del intercambiador y de explotación (consumo eléctrico de la bomba de calor y costes de bombeo asociados). [CA] Un dels majors reptes per al mercat de bombes de calor geotèrmiques és l'alt cost associat a la perforació dels bescanviadors de calor geotèrmics. Aconseguir uns bescanviadors de calor geotèrmics més eficients reduiria aquest cost, ja que seria necessària una menor longitud de bescanviador per a obtenir les mateixes temperatures de treball en ell (mateixa eficiència de la bomba de calor). L'eficiència tèrmica d'un bescanviador de calor geotèrmic està caracteritzada per la seva resistència tèrmica. Aquesta resistència tèrmica depèn d'una sèrie d'elements entre els quals es troben: propietats i cabal del fluid que recorre el bescanviador de calor, diàmetre de la perforació geotèrmica, geometria i materials de la canonada del bescanviador de calor i les propietats del material de farciment de la perforació (grouting). Com més gran sigui la resistència tèrmica del bescanviador de calor, menor serà la calor transferida entre el fluid termòfor i el terreny, traduint-se en una necessitat major de longitud de bescanviador enterrat. Per tant, és necessari una reducció d'aquest paràmetre al mínim possible. En conseqüència, l'objectiu principal d'aquesta Tesi Doctoral consisteix en, a partir d'un model analític comprensiu de quantificació de l'impacte dels paràmetres anteriors, realitzar un estudi detallat per a analitzar la seva influència combinada en la resistència tèrmica del bescanviador geotèrmic, però també examinant aquest efecte en altres plans, com a costos econòmics d'execució del bescanviador i d'explotació (consum elèctric de la bomba de calor i costos de bombament). [EN] One of the biggest challenges for the ground source heat pump market is the high cost associated with drilling geothermal borehole heat exchangers. Achieving more efficient geothermal heat exchangers would reduce this cost, since a shorter exchanger length would be required to obtain the same working temperatures in it (same efficiency of the heat pump). The thermal efficiency of a geothermal heat exchanger is characterized by its borehole thermal resistance. This borehole thermal resistance depends on a number of parameters, mainly: properties and flow rate of the working fluid that flows through the borehole heat exchanger, diameter of the geothermal borehole, geometry and materials of the heat exchanger pipe and the properties of the borehole grouting material. The higher thermal resistance of the heat exchanger, the less heat is transferred between the heat carrier fluid and the ground, resulting in an increased requirement for the length of the buried heat exchanger. Consequently, it is essential to reduce this parameter to the minimum possible. Therefore, the main objective of this Ph. Doctoral Thesis is to carry out, based on a comprehensive analytical model of quantification of the impact of the above mentioned parameters, a detailed study to analyze their combined influence on the thermal resistance of the geothermal borehole, but also exploring this effect in other less researched areas, such as economic costs of running the exchanger and operating it (electricity consumption of the heat pump and associated pumping costs).

Abstract:

The authors closely analyzed 45 children's books featuring characters with refugee backgrounds that had been published since 2013. With the concept of culturally sustaining pedagogy underpinning the review, analysis revealed that these texts are rich and detailed, providing a starting point for discussing the global refugee crisis with students, but they occasionally fall short in providing complex, multidimensional representations of characters’ lives and experiences. A majority of the texts analyzed focus on the journey in search of a safe place to live, whereas very few focus on the complexity of making a life in a new place. The findings highlight the importance of identifying texts that provide complexity, dimension, and specificity in depicting experiences of refugee‐background characters across settings. Opening classrooms to texts about the diversity of refugee experiences invites teachers and their students to critically explore the important global issues of migration, equity, and ways of being human.

Abstract:

Background Transgender individuals face numerous health disparities and report negative experiences with health care providers related to their gender identity. Significant gaps in medical education regarding transgender health persist despite calls for increased sexual and gender minority content. The purpose of this student‐led study was to assess the effectiveness of a half‐day educational intervention on first‐ and second‐year medical students’ attitudes and knowledge of transgender health. Methods Students and faculty members collaborated to develop an educational session on transgender health. This content was presented to first‐ and second‐year medical students at Integrated Grand Rounds, a pedagogical method in which basic science and clinical faculty members co‐present didactic content interspersed between live patient interviews and student‐led small group discussions. Student participants (n = 138) completed voluntary 9‐item pre‐ and post‐session surveys assessing comfort with and knowledge of transgender medicine. Results Students’ comfort with and perceived knowledge about transgender patients increased significantly between pre‐ and post‐test. Students’ knowledge of transgender medicine standards of care also improved, though not all items reached significance. Discussion A half‐day educational intervention improved many facets of medical students’ attitudes and knowledge about transgender patients. The significant disparities in physical health, mental health and access to care currently experienced by transgender persons in the United States warrants the continued testing and refinement of educational interventions for future and practising providers.

Abstract:

Unlike infrastructure-based networks, mobile ad hoc networks consist of nodes independent of any infrastructure. Cooperation among these nodes is essential for the sustenance of multi hop communication. However, battery and bandwidth constraints may lead nodes in an ad hoc network to adopt energy- and bandwidth-conserving strategies. As routing and packet forwarding are end results of cooperation, network performance is affected when nodes in the network behave selfishly to conserve their resources. Our work involves characterizing selfish behavior by nodes in ad hoc networks and assessing the effectiveness of adopting tit for tat based strategies, which are meant to discourage selfish behavior in the network. We show that in an ad hoc network where other nodes act selfishly to conserve their resources, a node can benefit by adopting a generous tit for tat strategy. We also show that a node can gain benefit by avoiding selfish nodes in an ad hoc network, adopting a strategy that we call generous tit for tat with selfish avoidance (GTFT-SA). To analyze the effectiveness of cooperation strategies in selfish ad hoc networks we create an emulation environment based on virtualization. Such an emulation environment is more flexible to changes and is simpler to replicate than real life testbeds, while providing higher fidelity than simulations. Master of Science

Abstract:

In Axelrod's tournaments of the Prisoner's Dilemma, carried out in the 1980s, a strategy called Tit for Tat was declared the winner, and it has since then been thought of as the strategy to use to do as well as possible in different situations. In this thesis, we investigate whether Tit for Tat will still do as well if we change the game to the Hawk-Dove Game. This is done by comparing Tit for Tat to other strategies -- All C, All D, Joss and Random -- one at a time. First we analyse under which conditions each strategy will be an Evolutionary Stable Strategy, then if it is possible for a population of these two strategies to end up in a stable polymorphism, and finally, if we have a finite population instead of an infinite one, under which conditions selection will favour the fixation of each of the strategies. This leads to the conclusion that how well Tit for Tat will do depends a lot on the different conditions on the game, but in general, the more times that a pair of individuals will meet, and the higher the value of the resource is compared to the cost of fighting, the better Tit for Tat will do.

Abstract:

The UK government’s Carbon Plan-2011 aims for 80% carbon emission reduction by 2050, and the 2009 UK National Renewable Energy Action Plan has set a target of delivering 15% of total energy demand by renewable energy sources by 2020. Ground Source Heat Pump (GSHP) systems can play a critical role in reaching these goals within the building sector. Achieving such benefits relies on proper design, integration, installation, commissioning, and operation of these systems. This work seeks to provide evidence to improve the practices in design, installation and operations of large GSHP systems. This evidence has been based on collection and analysis of data from an operational large-scale GSHP system providing heating and cooling to a university building. The data set is of significance in that it is collected from a large-scale system incorporating fifty-six borehole heat exchangers and four heat pumps. The data has been collected at high frequency since the start of operation and for a period of three years. The borehole heat exchanger data is intended to form a reference data set for use by other workers in model validation studies. The ground thermal properties at the site have been estimated using a novel combination of numerical model and parameter estimation methods. The utility of the reference data set has been demonstrated through application in a validation study of a numerical borehole heat exchanger model. The system heat balances and power consumption data have firstly been analysed to derive a range of performance metrics such as Seasonal Performance Factors. Analysis has been carried out at the system and individual heat pump level. Annual performance has been found satisfactory overall. A series of analyses have been carried out to investigate the roles of circulating pump energy, control system operation and dynamic behaviour. Monitoring data from one of the heat pumps has also been analysed in further detail to make comparisons with manufacturer’s steady-state performance data and with consideration to variations in fluid properties. Some modest degradation from stated performance has been identified. The most significant operational factors accounting for degradation of overall system performance have been excessive pump energy demands and short cycling behaviour. Some faults in operation of the system during the monitoring period have also been identified. A series of recommendations are made as to ways to improve the design and operation of large-scale GSHP systems based on this evidence. These recommendations are chiefly concerned with better design for part-load operation, reduction in pump energy demands and more robust control systems.

Abstract:

Les lymphocytes T expriment à leur surface des récepteurs (TCR) composés de chaînes a~ ou y8, chargés de reconnaitre des peptides antigéniques. Une chaîne d'un TCRa donnée est le résultat de l'assemblage de gènes variable (V), jonction (J) et constant (C) sous le contrôle d'un mécanisme de recombinaison spécifique dénommé «recombinaison V(D)J ». De part le nombre important de gènes V et J dispersés sur plus de 1méga base et des segments V dupliqués chez la souris, il est quasiment impossible d'établir la diversité combinatoire VJ exacte et surtout leurs fréquences par les techniques actuelles de biologie moléculaire. Aussi pour appréhender ces questions, nous avons développé un modèle de simulation des ré arrangements des combinaisons VJ codant pour la chaine TCRa chez la souris. Le modèle implémenté est basé sur des fenêtres d'accessibilités flexibles, des vitesses d'ouverture variables et inclue aussi un temps de maturation entre deux ré arrangements. Il permet de rendre compte de la dynamique et de la variabilité de la chaine a en termes de répertoire (nombre et fréquence des combinaisons). Il propose que 2 à 3 réarrangements sont suffisant pour utiliser l'ensemble des segments J et permet aussi de donner un profil global de l'ensemble des combinaisons VJ. En parallèle, une analyse des réarrangements VJ a été réalisée chez l'homme. Cetteanalyse permet de visualiser les profils des combinaisons VJ expérimentaux et permettra de valider l'adaptation du modèle de simulation des réarrangements des chaines TCRa chez la souris aux chaines TCRa chez l'homme. Le modèle pourra servir d'outils pour analyser les variations entre répertoire sain et répertoire altéré ou modifié dans le cas de pathologies T lymphocytes express at their surface an antigen receptor composed by a~ or y8 chains. A TCRa chains are encoded by a variable (V), ajoining (J) and a constant (C) segments which are under the of the control of a specific recombination mechanism called "V(D)J recombination". The VJ combinatorial diversity is unknown and the current state of molecular technology does not allow us to perform an analysis of aIl putative VJ combination or to estimate the frequencies of the functional VJ in mice. To overcome this difficulty we defined a mathematical model fitting experimental data. This model gives new insights on the mIes controlling the use of the V and the J genes and provides a dynamic ca1culation of the VJ combinations. The model proposes an accessibility of the TRAlTRD locus by sûccessive windows of different sizes and with different speed of progression. Furthermore, a possibility of successive secondary rearrangements was introduced. Ln parallel, an experimental analysis of the VJ combination has been performed in humans. From this analysis, the VJ combination profiles are ca1culated and used to validate our simulation program. Ln the future, the model may be use to analysis the variations between sound or altered repertoire

Abstract:

Studiens syfte var att undersöka om, och i det fall det sker hur, man arbetar med småbarns rörelseträning i förskolan. Undersökningen gjordes utifrån en kvalitativ ansats med fokus på småbarn i åldern 1-3 år i förskolans verksamhet. Tre förskolor i Sundsvalls kommun valdes ut och datainsamlingen genomfördes med hjälp av metodtriangulering (intervju, kartläggning avden fysiska miljön och innehållsanalys). Intervjuer med chef, personal och förälder vid respektive förskola visade att dessa förskolor inte planerar och jobbar aktivt med rörelseträning. Kartläggningen av den fysiska miljön med utgångspunkt i Björklids kunskapsöversikt (2005) visar att utomhusmiljön inte är naturrik och inomhusmiljön uppvisar brister. En av förskolorna saknade verksamhetsplan och målen formulerade av de andra två förskolorna utgör ett tunt underlag vad gäller rörelseträning. I Läroplan för förskolan Lpfö 98 beskrivs dock vikten av motorik och rörelse. Godkännandedatum 2008-10-10

Abstract:

La tesi si propone di porre a confronto tre raccolte di stampe appartenute a cittadini padovani vissuti a cavallo tra il XVIII e il XIX secolo a partire dai cataloghi a stampa delle loro collezioni, al fine di trarre delle considerazioni significative sul mercato, sul gusto e sulla diffusione di incisioni in questo periodo storico. Ad una introduzione generale sugli studi, sulla critica, sul mercato e sul collezionismo di stampe tra Settecento e Ottocento a livello italiano con le necessarie connessioni europee, ha fatto seguito una presentazione del panorama collezionistico padovano e in particolare delle raccolte di incisioni costituitesi in questi anni. Si rilevano nello specifico tre collezioni a Padova, quelle di Federico Manfredini, di Luigi Gaudio e di Antonio Piazza, il cui catalogo è stato redatto nella prima metà dell’Ottocento. Dopo aver presentato i profili dei collezionisti, l’analisi si è concentrata sui cataloghi per cercare di individuare quali fossero le modalità di raccolta dei collezionisti, gli incisori più ricercati, le prove più richieste, i soggetti e le tecniche. Inoltre, grazie allo spoglio dei principali manuali sull'incisione coevi, è stato possibile risalire ai prezzi a cui le stampe venivano vendute e individuare i fattori che determinavano le oscillazioni del valore di un’incisione nel mercato calcografico del tempo.

Abstract:

The study is devoted to the painter Zanino di Pietro, who was mainly active in Venice between the 14th and 15th centuries. Indeed, this artist was an eminent personality of the Late Gothic period and took part to the transition of the artistic scene from the neo-Giottesque style to the International style introduced in the Lagoon by Gentile da Fabriano. The goal of the research was to rebuild Zanino di Pietro’s catalogue, analyzing every artwork attributed to the painter and trying to resolve some critical issues or various attributions so far unresolved. The research was carried out deepening the master's artistic development together with his biography: from this viewpoint, the archival research made in different Italian cities has been an important part of the work. It has brought to light some unpublished documents concerning Zanino di Pietro’s links with patrons and the artistic context of his time. These findings have given the opportunity to identify more references and dates to support the reconstruction of his corpus. Furthermore, an important part of the study is dedicated to his workshop and the artistic influences that the painter received throughout his career. Lo studio è dedicato al pittore Zanino di Pietro, attivo principalmente nel contesto veneziano fra i secoli XIV e XV. Si tratta di un’importante personalità del periodo tardo-gotico e di un esponente di spicco del momento artistico che in laguna vide l’avvicendarsi di diverse tendenze pittoriche, dal neogiottismo della fine del Trecento alla maniera di Gentile da Fabriano. La ricerca ha ricostruito l’intero catalogo del pittore, analizzandone ogni opera e cercando di risolvere una serie di problematiche critiche o attribuzioni irrisolte: attività condotta approfondendo l’evoluzione artistica del maestro insieme alle sue vicende biografiche. La ricerca archivistica, svolta in diversi archivi italiani, ha permesso la scoperta di alcuni documenti inediti riguardanti i legami di Zanino con committenti e con la società del suo tempo. Questi ritrovamenti hanno quindi permesso di individuare più riferimenti e appigli cronologici utili alla ricostruzione del suo corpus. Inoltre un’importante parte dello studio è stata dedicata al funzionamento della sua bottega e alle influenze artistiche che il pittore recepì nel corso della sua carriera.

Abstract:

L’obiettivo di questo lavoro di tesi è quello di valutare se una rete logistica europea del tipo “Stabilimento produttivo – Centro di distribuzione – Cliente” possa essere sia Lean che Green ad un costo sostenibile per le aziende. Per rispondere a questa domanda si può ricorrere alla ricerca operativa. Si è definito un problema di ottimizzazione multi-obiettivo di tipo outbound in cui si è cercato di minimizzare il valore di tre funzioni, rispettivamente rappresentanti la logica Lean, la logica Green e i costi associati alla rete oggetto dell’analisi. I risultati ottenuti hanno evidenziato che, prese singolarmente, le filosofie Lean e Green conducono a prestazioni opposte. Minimizzando la sola funzione Lean si generano alti livelli di emissioni e costi, azzerando però le giacenze. Concentrandosi solo sulle emissioni, invece, si ottengono elevati livelli di scorte e costi che incrementano proprio a causa di tali valori. Si è così deciso di valutare un trade-off tra le tre funzioni obiettivo considerate, al fine di ottenere una configurazione di rete che soddisfi Lean, Green e Costi. I risultati confermano che tale trade-off è possibile, infatti, il punto di ottimo selezionato presenta un costo prossimo al miglior risultato ottenibile, con emissioni di poco superiori all’ottimo Green e con una quantità di giacenze accettabile lungo tutta la rete logistica.

Abstract:

Il lavoro si propone di indagare le interconnessioni tra il piano spaziale e temporale nella letteratura di viaggio attraverso l'analisi di tre casi di studio collocabili nell'arco del Novecento: il resoconto del viaggio in Sardegna di Elio Vittorini (Sardegna come un'infanzia), quello esito dell'esperienza sovietica di Carlo Levi (Il futuro ha un cuore antico. Viaggio nell'Unione Sovietica) e i resoconti dei viaggi africani di Alberto Moravia (A quale tribù appartieni?; Lettere dal Sahara; Passeggiate africane). Il focus dell'attenzione è posto sulle modalità attraverso cui una realtà nuova e sconosciuta viene letta dall'autore attraverso le lenti del tempo. Sono analizzati i processi che attivano i richiami e i riferimenti al tempo passato, che può configurarsi come il tempo dell'infanzia e del sogno (Vittorini), del mito e della comunanza di origini (Levi), ma può assumere anche i tratti dell'assenza di storia (Moravia).

La quantification expérimentale de certaines associations V -J chez la souris a permis de définir les tendances des répertoires combinatoires thymiques et périphériques. Un modèle numérique stochastique, basé sur des fenêtrages d'ouverture successives progressant sur les régions V et J durant les cycles de réarrangements, a permis une meilleure compréhension des règles dynamiques gouvernant les réarrangements V -J et a apporté la connaissance d'un répertoire combinatoire simulé renseignant les fréquences de toutes les associations V-Jo Lors de la transition à l'homme, la quantification des associations V -J a été réalisée au niveau du thymus, constituant un premier échantillonnage à large échelle du répertoire combinatoire TRA humain. L'étape de modélisation a offert une compréhension claire de la construction dynamique du répertoire a humain et a permis de proposer des prédictions sur la diversité du répertoire combinatoire. Finalement, la progression de l'accessibilité des gènes aux réarrangements selon des vitesses d'ouverture non-constantes associée à une ouverture synchronisée des régions J entre les deux allèles se sont révélées suffisantes pour expliquer les fréquences V -J expérimentales présentement disponibles pour les deux espèces ainsi que l'utilisation interalle��lique des gènes J.

As one strand of this miRNA was identified as an ortholog of cellular miRNA-155, their effects wereassessed on six cellular targets and on the UL-28 viral target. As a differential expression of miRNAs wasobserved during GaHV-2 infection, we found numerous IRL/TRL transcripts responsible for the intronic orexonic transcription of viral miRNAs.

Abstract:

Thesis (Ph. D.)--Massachusetts Institute of Technology, Dept. of Chemistry, 2002. Vita. Includes bibliographical references. Our research over the last four years has been focused on the development of mild and general methods for conducting palladium-catalyzed carbon-carbon bond forming reactions utilizing the bulky and electron-rich trialkylphosphine, tri-tert-butylphosphine (P(t-Bu)3). We have concentrated on the utilization of aryl chlorides as substrates due to their lower cost and greater availability compared to traditionally employed aryl bromides, iodides, and triflates. The Suzuki reaction was the first reaction that we investigated, and we were able to develop a first-generation protocol for coupling aryl chlorides with aryl-boronic acids utilizing Pd2(dba)3/P(t-Bu)3 as catalyst and Cs2CO3 as base. A second-generation protocol utilizing KF as base offered significant improvements and provided an opportunity to expand the scope of the reaction. Electron-deficient aryl chlorides underwent Suzuki reaction at room temperature. Hindered substrates and unactivated vinyl chlorides could be coupled efficiently, and turnover numbers as high as 9,700 could be achieved. In addition, we discovered a highly unusual selective coupling of an aryl chloride in preference to an aryl triflate. The next reaction that we examined was the Heck reaction, and we were able to develop a method for coupling aryl chlorides with olefins using Pd/P(t-Bu)3 as catalyst and Cs2CO3 as base. A significant improvement in terms of scope and mildness of conditions was realized with the replacement of Cs2CO3 with Cy2NMe, which allowed for the coupling of sterically and electronically diverse aryl bromides at room temperature, as well as the first room-temperature Heck couplings of aryl chlorides. (cont.) A wide variety of olefins could be employed in these couplings, including disubstituted olefins. In addition, these Heck reactions could be performed on multigram scale with minimal purification of starting materials, emphasizing the practicality and robustness of this method. Prior to 1999 there were no reports of palladium-catalyzed Stille couplings of unactivated aryl chlorides; utilizing Pd/P(t-Bu)3 in tandem with a fluoride activation strategy, we were able to develop the first general method for Stille couplings of aryl chlorides. More recently, we have considerably increased the scope of this reaction, including the synthesis of tetra-ortho-substituted biaryls, selective couplings of chlorides over triflates, and couplings of some aryl chlorides at room temperature. We have also undertaken mechanistic, kinetic, and reactivity studies using 1H NMR, P NMR, and GC. As a result of these studies, we believe that a monophosphine palladium species is the active catalyst in many of these couplings. The bisphosphine palladium complex Pd(P(t-Bu)3)2 is the resting state; yet by itself it is an ineffective catalyst for room-temperature couplings of aryl chlorides. The addition of phosphine-free Pd2(dba)3 to Pd(P(t-Bu)3)2 generates an efficient catalyst for room-temperature couplings and inspired us to try to utilize crystalline and now commercially available Pd(P(t-Bu)3)2 as a catalyst to eliminate the need to handle air-sensitive P(t-Bu)3. For the most part we have been quite successful in this regard; mixtures of Pd(P(t-Bu)3)2 and Pd2(dba)3 are efficient catalysts for many room-temperature couplings of aryl chlorides. ... by Adam F.

Abstract:

L’acqua è, da sempre, l’elemento costitutivo che ha reso possibile lo sviluppo della vita sulla terra.Dal punto di vista storico sappiamo che l’acqua ha da sempre rappresentato un elemento costitutivo per tutte le grandi civiltà umane, dagli egizi ai romani (Solomon, 2010).L’acqua non ha perso il suo ruolo centrale neanche nel mondo moderno e secolare, oggi vengono definite “blue space” tutte quelle superfici acquatiche, quali canali, fiumi, laghi, torrenti, che rendono un paesaggio unico nel suo genere e con qualità migliorative per la vita degli esseri umani, sia dal punto di vista fisico che psicologico.L’attaccamento e l’amore dell’essere umano nei confronti dell’elemento acqua è evidente, tanto che oggi possiamo utilizzare il termine di idrofilia, intendendo con questa parola lo specifico apprezzamento dell’uomo per gli ambienti acquatici (Vallerani, 2019). L’acqua rappresenta poi, dal punto di vista energetico, la fonte rinnovabile più importante nella storia dell’umanità. La prima diga, infatti, fu costruita da loro, e furono anche tra i primi popoli a sfruttare l’invenzione della ruota idraulica, tecnologia che, se collocata nei fiumi e nei torrenti, trasforma l’energia cinetica in energia meccanica. Con il passare dei secoli l’acqua non ha perso d’importanza, questo elemento così prezioso darà il via alla seconda rivoluzione industriale (fra la fine del 1800 e l’inizio del 1900) quando l’energia idrica venne utilizzata per produrre energia elettrica, avviando la pratica idroelettrica e la costruzione delle prime centrali. L’avvento dell’elettricità cambiò radicalmente la vita di intere aree europee. Le aree montane, fino ad allora relegate ai margini degli stati e degli imperi, assumevano ora un nuovo ruolo di fondamentale importanza, proprio per la presenza di ruscelli, fiumi e laghi che, dalle pendici montane, scendevano verso valle e che potevano essere ora utilizzati per la produzione di questa nuova ed indispensabile energia.Di colpo le vallate montane assumevano un importante valore in tutto il contesto europeo. Oggi questi luoghi, un tempo adibiti alla produzione di energia elettrica, sono diventati meta di nuovi percorsi turistici, che coniugano sapientemente la suggestione del paesaggio alla valorizzazione di strutture architettoniche di peculiare interesse. Mia intenzione è quella di dare a questa tesi un taglio di tipo storico, culturale ed antropologico, che, partendo dal concetto di idrofilia e di blue space, andrà ad analizzare alcuni laghi artificiali collocati in ambiente montano, un tempo adibiti alla produzione di energia idroelettrica e oggi rivitalizzati, diventando mete turistiche e sportive. Nello specifico prenderò in esame la Francia, dove analizzerò il lago di Sainte-Croix du Verdon, nella regione dell’alta Provenza. Cercherò di delineare la storia del luogo, l’impatto culturale e sociale che l’avvento dell’elettricità ha comportato per la comunità, e gli scenari turistici e di rilancio territoriale che sono emersi negli ultimi decenni. Mi sposterò poi ad analizzare un caso italiano, quello della centrale idroelettrica trentina di Fies, costruita agli inizi del 1900, oggi diventata una delle più importanti testimonianze di archeologia industriale della regione. In questa parte dello scritto mi concentrerò sull’importanza architettonica ed artistica delle centrali storiche costruite in quegli anni in Italia e sul ruolo di riscoperta turistica di queste aree, un tempo adibite alla produzione industriale ed energetica. Infine mi sposterò più a nord, in Baviera, sul lago Forggensee , dove un lago artificiale e la sua imponente diga sono diventate oggi meta di turisti dediti alla ricreazione lacustre, un lago artificiale che ha profondamente modificato il naturale fluire delle acque del fiume Lech.

Abstract:

La tesi è incentrata sui recenti sviluppi della narrativa testimoniale dell’America Latina. Verranno presi in considerazione gli ultimi contributi critici dedicati al rapporto tra finzione e realtà in letteratura, e sarà dato spazio alla costruzione narrativa della realtà e alla nascita del testimonio, come genere a sé, che raccoglie alcune delle principali opere latinoamericane degli ultimi quaranta anni. Nello specifico, l’indagine riguarderà la rappresentazione letteraria della violenza nella narrativa di denuncia di tre autori ispoanoamericani: la novela negra di Enrique Serna, il poliziesco testimoniale di Rodolfo Walsh e la scrittura estrema di Roberto Bolaño. Obiettivo della ricerca è capire in che modo i tre scrittori hanno raccontato le loro verità alternative, provando a salvaguardare la memoria, e quali effetti hanno ottenuto. Verranno analizzate non solo le tematiche affrontate, facendo riferimento quindi al contesto storico, politico e sociale al quale si rifanno, ma saranno illustrate anche le differenti tecniche di costruzione del romanzo, dell’intreccio e della trama, e verrà isolato il ruolo del testimone (diretto o indiretto) e delle fonti, per cogliere le differenze ma anche le similitudini stilistiche e narrative di ognuna delle opere. Più in generale, dimostreremo come e quanto i testi di questi autori costituiscano in realtà una forte critica al sistema imperante e diano voce alle categorie sociali altrimenti emarginate. The thesis is focused on the recent developments of the Latin American testimonial narrative. The last critical contributions dedicated to the relationship between fiction and reality in literature will be taken into consideration and room will be given to the narrative construction of reality and the birth of witness literature, as a genre in itself, which collects some of the major works in Latin America over the last forty years. Specifically, the survey will concern the literary representation of violence in the narrative report of three Spanish-American authors: Enrique Serna’s novela negra, Rodolfo Walsh’s police witness and Roberto Bolaño’s extreme writing. The objective of the research is to understand how the three writers have told their own truth alternatives while trying to preserve memory, and what effects they've had. They will be analyzed not only the main topics through the historical, political and social context they refer to, but also the different construction techniques of the novel, storyline and plot. It will also be blocked the role of the witness (direct or indirect) and sources, to understand differences and similarities of style and narrative among the three authors’ works. More in general, we will demonstrate how and how much the texts of these authors constitute a strong critique of the prevailing system and give voice to otherwise marginalized groups in society.

The last critical contributions dedicated to the relationship between fiction and reality in literature will be taken into consideration and room will be given to the narrative construction of reality and the birth of witness literature, as a genre in itself, which collects some of the major works in Latin America over the last forty years. Specifically, the survey will concern the literary representation of violence in the narrative report of three Spanish-American authors: Enrique Serna’s novela negra, Rodolfo Walsh’s police witness and Roberto Bolaño’s extreme writing. The objective of the research is to understand how the three writers have told their own truth alternatives while trying to preserve memory, and what effects they've had. They will be analyzed not only the main topics through the historical, political and social context they refer to, but also the different construction techniques of the novel, storyline and plot. It will also be blocked the role of the witness (direct or indirect) and sources, to understand differences and similarities of style and narrative among the three authors’ works. More in general, we will demonstrate how and how much the texts of these authors constitute a strong critique of the prevailing system and give voice to otherwise marginalized groups in society.

Abstract:

The correlative relationship of growth rate constant, environmental variables and life history traits was studied in the nestlings of the great tit, the willow tit, the crested tit and the blue tit in the Oulu area of northern Finland in 1969, 1977–1981 and 2017. All the species reached their species specific asymptotic weights by the age of 13–14 days. The asymptotic weight of the great tit was relatively lower than the adult weight compared with the other parids studied. The mortality rate of the nestling great tits was higher than of the crested and willow tits in 2017. Large intial brood size pose an negative imapct on the great tit mass growth. It is possiblely related to the high energy maintainence from the parents and unpredictable weather reduces food supply. The high number of hatchlings seems to be related to increasing nestling mortality in the great tit. After the brood reduction, parents can better nourish the rest of the nestlings which leads to a positive association between the number of fledged chicks and the growth rate constant. We did not find any significant relationship between the ambient temperature and growth rate constant in any of the species. It can be associated with the method of collecting the temperature data. However, the amount of rainfall during the nestling period was positively related to the wing growth rate constant in great tits. The late hatched willow tit nestlings grew faster than the early nestlings. There was a trade-off for the timing of breeding in the willow tit. The early nestling might be able to prepare themselves into breeding population while the late nestling might receive better nourishment from their parents. Besides, the brood size at hatching were markedly related to the growth rate constant in the willow tit. This possibly reflects the female quality and habitat quality in the Oulu area. The growth rate constant of different species was related to the body size, clutch size, and species specific breeding strategies.
