In hydropower plants it is necessary to always have local power supply. Therefore, the plants are equipped with batteries as stationary back up power. Vattenfall Vattenkraft is using lead acid batteries but has been investigating alternatives to replace them. The aim of this study is to investigate the potential of using Li-ion technology as back up power. The study showed that Li-ion batteries have many qualities. The Li-ion technology will decrease the space and maintenance demand. The technology also eliminates many of the personal safety risks that lead acid batteries may cause. Unfortunately overcharging or overheating the Li-ion battery may result in fire or explosion. Those risks are reduced by an electronic battery management system and mechanical protection. The result from the cost comparison between the two battery technologies showed that the maintenance costs decreases with 70 % when using Li-ion battery. The purchase cost of Li-ion batteries is almost three times higher compared to lead acid batteries. But prices will probably drop drastically in the coming years. According to this study Li-ion has great potential to replace the lead acid battery.  Vattenfall Vattenkraft should wait until the technology develops further and prices decrease before any larger installations are made. But small installations should be considered in order to get more experience of the technology.

The work is a reflection of my opinions and criticism of society and the world as I see it. The absurd behavior of individuals in my environment provided the basis for my research. The seven woodcut prints that were completed, attempted to examine universal and personally significant themes.I utilized visual techniques to convey personal feelings and ideas about relationships with other people. Technical as well as conceptual abilities were drawn upon to produce a series of prints that depicted specific experiences I have had in life. / Department of Art

Examinamos, neste trabalho, o sentido do termo "pobre" na obra O princípio misericórdia de Jon Sobrino, a partir do pensamento do sociólogo Pierre Bourdieu. A ideia do pobre como sacramento de Deus vem sendo transmitida por longa tradição. Essa tradição volta a aparecer no cristianismo profético da teologia da libertação especialmente em Jon Sobrino. Procurei inferir subsídios para uma nova hermenêutica do pobre, não mais como uma categoria sociológica, porém como sacramento. A razão simbólica em Jon Sobrino se caracteriza pela gratuidade, sua luta simbólica tenta mudar as categorias de percepção e apreciação do mundo social, as esruturas cognitivas e de avaliação. Quatro momentos dão estrutura a esta dissertação. O primeiro enfocará as questões de ordem teórico-metodológica da pesquisa, especificamente a teoria do poder simbólico, espaço social e violência simbólica em Pierre Bourdieu, que serão utilizadas para compreender o conteúdo da categoria "pobre" em Jon Sobrino. O segundo momento verificará os possíveis sentidos do termo pobre a partir da teoria da dominação simbólica em Pierre Bourdieu. No terceiro momento, analisaremos as diversas representações sobre a pobreza, na produção de alguns teólogos da libertação na América latina, articulando com o sentido dado por Jon Sobrino. E, por fim, no quarto momento, verificaremos as transformações semânticas do termo pobre em O Princípio Misericórdia

The purpose of the project was to carry out a study of a potential solar cell facility at Västergårdsgymnasiet. Previous studies have established that there is the greatest potential for electricity production during the summer period, which coincides with the load at its lowest. The aim of the project was therefore to investigate a solar cell plant with energy storage and how the surplus of the electricity produced can be stored.The modeling was performed with an installed capacity of 1231 kW solar panels and evaluated with the software Homer Pro, which is designed to simulate and optimize local energy systems. The execution of the project was divided into four main steps, the first being to check the solar-power plant's potential by calculating the theoretical electricity production against the property load. From this, the theoretical surplus could also be calculated, which is the cornerstone of the other main elements. The simulation resulted in the annual electricity production level being approximately 1.2 GWh and the theoretical surplus was estimated to be 0.5 GWh. The surplus in the system is sold to the electricity grid with a financial compensation based on Nordpool's spot prices. The financial result showed that it was not profitable with the conditions that the facility has and sensitivity analysis depending on the spot price was performed. The remaining three main steps are based on different types of energy storage methods, these are storage with lithium-ion batteries, flow batteries and hydrogen storage. The purpose of these energy storage methods was to reduce the proportion of electricity sold to increase the economic profitability and contribute to a higher degree of self-sufficiency.The systems with battery storage resulted in an increased degree of self-sufficiency but did not contribute to any increased economic profitability. The last storage method that was investigated was hydrogen storage, this was done with three different applications. The first application was based on the surplus of the produced solar energy being used to produce hydrogen. The produced hydrogen gas was then stored until the system has a shortage of energy and was then supplied to the fuel cell that produces both electricity and heat that were used in the property. The study showed that the method would not contribute to any economic profitability. The second application that was investigated was of the same basic structure as before but has been supplemented with a flow battery. The simulation of the system showed an increased degree of self-sufficiency but with a higher cost. The last method of application that was investigated was that the surplus energy is used to produce hydrogen, which was then used for an internal vehicle fleet or alternatively sold. The application gave promising results with the possibility of financial profitability.

Thesis advisor: O. Ernesto Valiente / Thesis advisor: Benjamin Valentin / The thesis focuses on two historical forms of oppression: economic and racial, as well as two attempts to theologize these phenomena: one by Jon Sobrino, an author writing from the perspective of El Salvador and Latin America, and the other by James H. Cone, the founder of black liberation theology. Both theologians construct a link between the contemporary oppressed and the theological categories of cross and salvation. In Cone's and Sobrino's view, the perspective of historical victims allows for a better understanding of the biblical account of Jesus' death and resurrection. At the same time, the reality of oppression itself can only be fully understood in the light of Jesus' story, which creates a specific hermeneutical loop. At the center of this thesis lies the category of the crucified people, essential to Sobrino's theology, and the analogy between the cross and the lynching tree introduced by Cone. The proposed analysis juxtaposes some key elements of the two authors' writings and the historical contexts of their reflections. It shows where their interpretations meet, in what elements they differ, and how they can aid each other in constructing the perspective of historical soteriology. / Thesis (STL) — Boston College, 2023. / Submitted to: Boston College.

This study analyzes 2008 presidential election coverage on The Daily Show with Jon Stewart and The Colbert Report to determine how they confront the tension between the genres of news and entertainment. To this point, much of the scholarly work on political entertainment news has focused on examining its effects on viewers' political attitudes and knowledge. A rhetorical analysis reveals the actual messages they convey and the strategies they employ to discuss contemporary American politics. Through comedic devices such as satire and parody, The Daily Show and The Colbert Report offer a venue for social commentary and criticisms of power at a time when traditional venues are dissipating, and these shows provide a place for serious political discourse that encourages dialogue that promotes civic engagement. / Master of Arts

A respeito da relação Kierkegaard-Hegel, foram diferenciadas duas perspectivas frente a ela: a primeira é a que visa a relação do ponto de vista psicológico, isto é, que pretende saber se Kierkegaard estava contra Hegel, se ele escrevia seus livros com o intuito de atacar Hegel; e a segunda, por sua vez, que visa a relação do ponto de vista filosófico ou teórico, isto é, concentra-se em saber se as críticas de Kierkegaard cabem à filosofia de Hegel, sem pretender saber se esse autor era o verdadeiro alvo kierkegaardiano. Para atingir seus objetivos, essa pesquisa adotou a segunda perspectiva. Esta dissertação também analisou a posição de Niels Thulstrup e Jon Stewart acerca dessa relação. A atenção foi concentrada no segundo deles, tido como o status quæstionis sobre a relação investigada – resultando, no posicionamento frente a ele, um objetivo secundário para essa pesquisa. A fim de oferecer uma outra interpretação a uma pequena parcela de sua visão geral e também a uma interpretação específica a respeito da relação Kierkegaard-Hegel, essa dissertação investigou a relação filosófica entre Kierkegaard e Trendelenburg. Os resultados da pesquisa são os de que há aspectos importantes da Ciência da Lógica de Hegel contidos no Pós-Escrito de Kierkegaard e que aí são criticados – fazendo com que a relação Kierkegaard-Hegel também seja teórica e crítica, e não apenas passiva ou inexistente acerca da lógica; item relativo à visão geral de Stewart –, que Kierkegaard e Hegel não têm a mesma posição a respeito do início da lógica – item relativo a uma interpretação específica de Stewart – e que as condições colocadas por Kierkegaard em "(a) um sistema lógico pode haver" têm influência trendelenburguiana e, assim, são incompatíveis com princípios defendidos por Hegel. / This Master’s dissertation aims to investigate Kierkegaard's criticisms of the Hegel's Science of Logic contained in his Postscript. In regard to the Kierkegaard-Hegel relationship, two perspectives have been differentiated from it: the first one is that which relates to the psychological point of view, that is, whether Kierkegaard was against Hegel, if he wrote his books for the purpose of attacking Hegel; and the second one, in turn, is concerned with the relationship from a philosophical or theoretical point of view, that is, it focuses on whether Kierkegaard's criticisms fit Hegel's philosophy, without pretending to know whether this author was the true Kierkegaardian target. To reach its objectives, this research had adopted the second perspective. This dissertation also analyzed the position of Niels Thulstrup and Jon Stewart on this relationship. Attention was focused on the second of them, considered as the status quæstionis on the investigated relation – resulting, in the positioning before him, a secondary objective for this research. In order to offer another interpretation to a small part of his overview and also to a specific interpretation of the Kierkegaard-Hegel relationship, this dissertation investigated the philosophical relationship between Kierkegaard and Trendelenburg. The results of the research are that there are important aspects of Hegel's Science of Logic contained in Kierkegaard's Postscript and criticized there – making the Kierkegaard-Hegel relationship also theoretical and critical, not just passive or non-existent about logic; item on the general view of Stewart – that Kierkegaard and Hegel do not have the same position regarding the beginning of logic – an item relating to a specific interpretation of Stewart – and that the conditions put by Kierkegaard in "(a) a logical system can be given" has a Trendelenburgian's influence and thus are incompatible with principles defended by Hegel.

No. of bitstreams: 1 Daniel Soza.pdf: 1362204 bytes, checksum: 7b36762fc06e3ba4b9a4e96348aec07b (MD5) Previous issue date: 2013-03-12 / Conselho Nacional de Desenvolvimento Científico e Tecnológico / O objetivo central desta pesquisa é desvendar possibilidades no estabelecimento de prováveis eixos básicos de uma cristologia pluralista da libertação, a partir das reflexões teológicas de Jon Sobrino (1938-) e Jacques Dupuis (1923-2004). Para tanto, se reconhecem cotidianamente os entrecruzamentos de sinais dos tempos, como as diferenças religiosas e as violações de direitos e injustiças sociais. A partir desta problemática, toma-se como hipótese a necessidade de se demonstrar a articulação em andamento entre perspectivas das teologias da libertação com perspectivas das teologias cristãs do pluralismo religioso, sinalizando um novo modo de fazer teologia. O trabalho aqui desenvolvido dialoga com os estudos culturais, especialmente com os conceitos de Homi Bhabha, o referencial teórico desta pesquisa, que possibilitou, criticamente, o entrelaçamento das perspectivas de Jacques Dupuis e Jon Sobrino. Para a construção desta cristologia, seguiu-se um tripé metodológico: revisão, reconstrução e reinvenção. O trabalho buscou revisar os discursos teológicos apresentados por Jon Sobrino e Jacques Dupuis; reconstruir as reflexões teológicas elaboradas por estes autores; e reinventar uma cristologia que se mostre como um terceiro espaço, um entrelugar discursivo, uma cristologia pluralista da libertação, que não é nem o um (a cristologia da libertação) nem o outro (a teologia cristã do pluralismo religioso), mas algo a mais, uma fala híbrida elaborada a partir de determinadas zonas de contato entre os autores. A pesquisa apresenta como eixos: (i) uma cristologia integral: vivenciada nos espaços cotidianos, com uma reflexão a partir das vítimas e do espírito das testemunhas; (ii) uma cristologia trinitária: refletida a partir d@ outr@ e centrada no mistério inesgotável, na humanização do divino e na força do Espírito; e (iii) uma cristologia reinoteocêntrica: vocacionada ao reino de Deus, numa tensão entre a parcialidade com as vítimas e a universalidade da ação de Deus, numa elaboração nas vias da mística e em um discurso cristológico estruturado na (des)missão. Tais eixos possuem implicações políticas, uma vez que esta cristologia se constrói como uma dupla função: é objeto de estudo e é espaço para a atuação política, reconhecendo que novos discursos e linguagens relacionam-se com novas atuações e mobilizações sociais.
