Item's OAI Record identifier: oai:bdtd.ufpa.br:298 / CNPq - Conselho Nacional de Desenvolvimento Científico e Tecnológico / Punching is normally a critical case in the design of reinforced concrete flat slabs. According to many design codes, punching develops in a more unfavorable way in cases where the load is asymmetrically applied, due to unbalanced bending moments at slab-column connections. In order to evaluate the normative prescriptions in these cases, 12 reinforced concrete oneway flat slabs ( c f ' between 36 and 58 MPa) were submitted to symmetric or asymmetric punching. The slabs dimensions were (1.800 x 1.800 x 110) mm with the load being applied through a metallic plate simulating a square column with (85 x 85 x 50) mm. This research had as variables, in addiction to the load position, the reinforcement rate in transversal direction, in order to evaluate their influence in the punching ultimate resistance of one-way slabs. Results for vertical deflections, concrete surface and flexural reinforcement strains, cracking pattern, observed ultimate loads and failure modes are presented and analyzed. Also were analyzed the estimates of 6 design codes, with 3 European and 1 North-American, beyond the versions from 1978 and 2003 of the Brazilian structural concrete design code. A numerical analysis using the Finite Elements Method to simulate the slabs behavior is presented and its results are compared to the experimentally observed ones. The results showed that, unlike the normative previsions, punching resistance doesnt reduce linearly with the increments in the loads eccentricities, with the flexural effects significantly influencing the ultimate punching resistance. Even in one-way slabs, the transversal reinforcement rate showed significant influence on the slabs force distribution, interfering in the punching resistance. / O puncionamento é normalmente uma situação crítica no projeto de lajes lisas de concreto armado. Segundo várias normas de projeto, o puncionamento se desenvolve de maneira ainda mais desfavorável nos casos onde o carregamento atua de forma assimétrica, graças a momentos desbalanceados na ligação laje-pilar. Visando avaliar as recomendações normativas para estas situações, foram ensaiadas 12 lajes lisas unidirecionais de concreto armado ( c f ' entre 36 e 58 MPa) submetidas a puncionamento simétrico ou assimétrico. As lajes apresentavam dimensões de (1.800 x 1.800 x 110) mm com carregamento sendo aplicado através de uma chapa metálica simulando um pilar quadrado com (85 x 85 x 50) mm. O trabalho teve como variáveis, além da posição de carregamento, a taxa de armadura na direção transversal, objetivando avaliar a influência destas armaduras na resistência última ao puncionamento de lajes lisas unidirecionais. São apresentados e analisados os resultados dos deslocamentos verticais, deformações na superfície de concreto e nas armaduras de flexão, mapas de fissuração, cargas últimas e modos de ruptura observados. Apresentam-se ainda os resultados da avaliação das recomendações de 6 normas de projeto, sendo 3 européias e 1 norte americana, além das versões de 1978 e 2003 da norma brasileira para projeto de estruturas de concreto. Foi realizada também uma análise numérica utilizando o Método dos Elementos Finitos para idealizar o comportamento das lajes, comparando-se os resultados desta análise elástica com aqueles verificados experimentalmente. Os resultados indicaram que, ao contrário do que as normas prescrevem, a resistência ao puncionamento não diminui de forma linear com o aumento da excentricidade do carregamento, com a flexão influenciando significativamente na resistência última ao puncionamento. Os resultados indicam também que, mesmo em lajes unidirecionais, a taxa de armadura transversal apresenta influência significativa na distribuição dos esforços na laje, interferindo na resistência à punção.

Item's OAI Record identifier: oai:bdtd.ufpa.br:300 / Two-way waffle flat slabs are structural elements of reinforced concrete supported directly on columns, under bending moments over the two directions, they improve the speed of the execution and save moulds and concrete and, consequently, labor. This work seeks to contribute for the study of the behavior of this kind of slab, as the shear resistance of the ribs and the punching in the solid area, through tests of 8 two-way reinforced concrete waffle flat slabs. Comparative analyses between the experimental results and estimated by national and international design codes had been carried out. The slabs were square, with 1.800 mm of side and total height of 140 mm. The cross section of the slabs was formed by ribs with 50 mm of width for the base and 100 mm for the upper base and the spaces between the ribs had been filled with EPS blocks (expanded polystyrene). The main variables considered were the type of shear reinforcement in the ribs (trusses, closed vertical stirrup and 45 inclined stirrup) and the use of 45 inclined stirrup as shear reinforcement in the solid region. They were presented and analyzed the results observed for the vertical displacements, deformation in the flexural and shear reinforcement, and the propagation of cracks. The values observed for failure loads were compared with the estimated ones. It was observed that the shear reinforcement in the ribs did not increase the failure loads and that the shear reinforcement in the solid region increased significantly the resistance of the slabs. / Lajes lisas nervuradas bidirecionais são elementos estruturais de concreto armado apoiados diretamente sobre pilares, sujeitas a solicitações importantes nas duas direções, possibilitam maior velocidade na execução da obra e economia considerável de formas e concreto e, conseqüentemente, mão-de-obra. Este trabalho visa contribuir para o estudo do comportamento deste tipo de laje, quanto a resistência ao cisalhamento nas nervuras e à punção na região maciça das lajes, através de ensaios de 8 lajes lisas nervuradas bidirecionais de concreto armado. Foram realizadas análises comparativas entre os resultados obtidos experimentalmente e os fornecidos por normas técnicas nacionais e internacionais. As lajes eram quadradas de lado igual a 1.800 mm de comprimento e altura total de 140 mm. A seção transversal das lajes foi formada por nervuras de 50 mm de largura na base menor e 100 mm na base maior e os vazios entre as nervuras foram preenchidos com blocos de EPS (poliestireno expandido). As principais variáveis consideradas foram o tipo de armadura de cisalhamento nas nervuras (treliça, estribo vertical fechado e estribo aberto inclinado a 45) e a utilização de estribo aberto inclinado a 45 como armadura de punção na região maciça. Foram apresentados e analisados os resultados observados para os deslocamentos verticais, deformação nas armaduras de cisalhamento e de flexão, e a propagação das fissuras. Os valores observados para cargas últimas foram comparados com os resultados estimados. Observou-se que as armaduras de cisalhamento nas nervuras não ocasionaram ganhos significativos na resistência última e que a armadura de punção elevou significativamente a resistência das lajes.

The aim of this thesis is to describe and analyze the geographical distribution of everyday criminality in the town of Borlänge during the year 2002 and to analyze which measures to be taken in the physical social planning to decrease this everyday criminality there. The term everyday criminality is here to be understood as those categories of crime that appear most frequently in the records of reports to the police every year. Here two kinds of crime have been in focus, thefts from cars and office burglary.In fulfilling this aim two main questions have been answered. The first one is how the everyday criminality was distributed geographically in the town of Borlänge during the year 2002. The second one is which measures to be taken in the physical social planning to decrease this everyday criminality in the town of Borlänge.In order to answer the first question a spatial autocorrelation analysis, Local Moran LISA has been used. This method is based on the measurement Moran´s I and shows the spatial autocorrelation for every single location. To answer the second question three different theories of crime prevention through environmental design have been studied and applied in the analysis. These are Jane Jacobs’ ideas about ”the living city”, Oscar Newman´s ideas about ”defensible space” and Ronald V. Clarke´s theories about crime prevention.The major conclusions that can be drawn from this thesis are that the risk of being exposed to thefts from cars, during the analyzed time period, was highest in Centrum and Hagalund and their surroundings. The lowest risk of being exposed to this type of crime was found in Domnarvet and Islingby, during the year 2002. The highest risk of being a victim of the crime office burglary was found in Hagalund and its surroundings and in the single area of Kvarnsveden. The corresponding lowest risk was found in Lergärdet and its surroundings and in Norra Backa and Kupolen. The measures that should be taken in order to decrease these types of criminality can be divided into overall changes and place-specific changes. When it comes to the crime thefts from cars a more attractive central business district, a better view of parking lots from nearby buildings, dividing of larger parking lot zones into smaller ones, migration of hidden parking lots and stronger access control to parking lots where problems with this kind of crime have occurred have been suggested as overall changes. The corresponding place-specific changes are to remove vegetation that is blocking the view, better lighting and to put up signs with information about increased risk of exposure to crime at parking lots with the most problems. To decrease the amount of office burglaries overall changes as to create a better view of the area from nearby surroundings, move bigger office compartments or divide them into smaller units, rebuild characteristic buildings and increase security by strengthening the access control to offices with these kinds of problems could be useful. Finally there are possibilities to decrease office burglary by using place-specific measures as surveillance cameras combined with signs containing information about these, high fences and better lighting around the buildings where a higher risk of being exposed to this kind of criminality is present.

In this thesis, Lisa Figge analyzes the political space of ecological citizenship by theorizing her art practice. Beginning with an Arendtian lens, Figge creates projects in the vein of New Genre Public Art, to trace the qualitatively-distinct activities of the public sphere, in which ecological citizens appear. The art practices of Mierle Laderman Ukeles, Colette Urban, Pat Aylesworth, Helen and Newton Harrison help move this critique along. Then, taking Judith Butler’s thinking on the bond between speech and action, or speech acts, Figge situates her art practice and thesis writing as an account of herself as an ecological citizen. Figge is interested in finding ways to multiply opportunities, for her and others, to perform concerned engagement with the world. In order to begin this process Figge acts out and analyses her three art interventions: Madame E and her suit of environmentally conscious a(r)mour, Ecological Citizen in Training, and 86 Hands on Wolfe Island. In giving an account of herself, she shows how our aptitude for sorting things should not be used to override our capacity to make a meaningful life. The art exhibition Dust to Dust, 2010 is the twin of this accounting, which was held at Queen’s University’s Union Gallery. / Thesis (Master, Environmental Studies) -- Queen's University, 2010-09-06 18:48:33.277

After studying this linguistic dictionary in manuscript: Al-Tahḏīb by Ibn Manẓūr, I realised the importance of studying and editing the manuscript. This research on Tahḏīb and the development of lexical studies and linguistics led me to note the strong relationships between classical and modern studies especially in Arabic linguistics. Here we can follow the developments of texts and the ideas behind them, both in dictionaries of different schools and in general linguistic works, from the beginnings of the study of the Arabic language, tracing the influence of Arabic studies on that of some eastern and western languages in the mediaeval period. Arabic grammar was developed by treating problems in spoken language. People were in need of rules to help them acquire correct style, to be able to understand the meaning of Qur'ān and Ḥadīth. The scholars, whose work has influenced present-day Arab linguistics and grammatical theory, based their studies on Qur'ānic texts and quotations taken from early poetry. The method of study was generally inductive. Moving from the particular to the general, the scholars discussed various language phenomena in booklets and books concerned with texts, listing words which they had heard from Arabs employing their own local usages and dialects. These indexes became the data of the lexicons and linguistic books. From the first study of Arabic, the linguists dealt with Al-Laḥn, the phenomena affecting the pronunciation of Arabic, observing the errors in the speech of the ordinary people, of the educated people, and even of the scholars. Al-Durrah by Al-Ḥarīrī was one of the most famous works in Arabic linguistics. To treat the scholars' errors rather than those of the ordinary people, it follows no system or method in its structure. Ibn Manẓūr had to classify its lexical items and to arrange them on his Lisān Al-Arab system, with a special critical approach. Some books written before Al-Durrah had the same aim to note Al-Laḥn. In Al-Durrah we can follow the train of those books, which dealt with linguistic materials, especially Adab Al-Kātib by Ibn Qutaiba which we consider an ancient precursor of Al-Durrah and on the other hand of Al- Tahḏīb, the dictionary which we are here editing for the first time.

For art to become personally meaningful to visitors, museums need to view art interpretation as a narrative inquiry process. General museum visitors without art expertise naturally make meaning of art by constructing stories around a work to relate to it. Narrative inquiry, a story based exploration of experience, fits into contemporary museum education theory because it is a constructive and participatory meaning making process. This thesis examines how art museums can build upon visitors' natural interpretive behaviors, by employing art-based narrative inquiry practices and using the work of art as a narrative story text. Individuals learn when their personal narrative comes into conflict with the narrative of the museum and they negotiate new meaning. This kind of narrative learning is a process of inquiry that visitors must engage in themselves. The art museum interpretive experience can foster in visitors the ability to engage in an art-based narrative inquiry process by suspending disbelief,recalling personal memories, comparing different narrative versions, imagining possible meanings, and re-storying experiences into new understandings. This research text explores these topics through a narrative based method of inquiry comprised of a series of autobiographical stories describing the researcher's experiences in coming to understand the relationship between narrative inquiry and art museum education.

This paper investigates three questions; how an exegetically sound basis for a biblical ethics concerning same-sex sexual acts might be construed, what role the Bible, and other sources of ethical insight, should play in construing Christian ethics, and what a Christian ethic founded on the answers to those questions would say concerning same-sex sexual acts today. To perform these investigations, the hermeneutical issue regarding biblical texts, as well as the relation between revelatory and non-revelatory ethical sources within Christian ethics, is discussed, and the construed Christian ethics concerning same-sex sexual acts and sexuality of Lisa Sowle Cahill, Samuel W. Kunhiyop, Richard B. Hays, and Peter Coleman are evaluated before a suggestion is presented. That suggestion states that a sound exegetical basis demands a historical-critical reading that aims at understanding the language agreement between first recipients and author(s). It also claims that it is the perspective of the text that should be in focus in forming biblical ethics. Further, it is suggested that the Bible should be considered as having a unique role in Christian ethics by means of supplying a unique perspective on other sources for ethics, as well as on the insights of Scripture itself. This perspective is based on revelation, and should be formed from the central Scriptural notion of imitatio Dei/Christi. The Bible should also be recognized as a unique source of Christian ethical insight. However, an awareness of the impossibility of perfect understanding of Scripture opens the need for a dialog with other sources of ethical insight, such as experience, tradition, and secular reason, through which they are able to play a role in construing Christian ethics. Finally, the Christian ethics concerning same-sex sexual acts holds such acts to be in need of a discriminating division between good and bad; those that are performed within a loving and caring relationship and those that are not. The former are tentatively commended based on an understanding of the clearly encouraged homosocial love they might result of, as well as positive human experience, while the latter are vehemently condemned because of their damaging nature to one or both of the people involved. / Uppsatsen undersöker tre frågor; hur en god exegetisk grund för en biblisk etik angående samkönade sexuella handlingar kan utformas, vilken roll Bibeln och andra källor till etisk insikt ska ha i utformandet av kristen etik, och hur en kristen etik baserad på svaren på dessa två frågor skulle se på samkönade sexuella handlingar idag. För att undersöka dessa frågor kommer hermeneutiska frågor angående bibeltexter likväl som relationen mellan uppenbarelsebaserade och icke-uppenbarelsebaserade källor till etisk insikt inom kristen etik att diskuteras. De konstruktioner av kristen etik angående samkönad sexualitet som gjorts av Lisa Sowle Cahill, Samuel W. Kunhiyop, Richard B. Hays och Peter Coleman utvärderas också innan ett eget förslag presenteras. Det förslag som sedan presenteras menar att en god exegetisk grund kräver en historisk-kritisk läsning som söker förstå den språkliga överenskommelse som fanns mellan ursprunglig(a) mottagare och författare. Förslaget menat också att det är textens perspektiv som ska vara i fokus i utformandet av en biblisk etik. Vidare föreslås det att Bibeln ska anses ha en unik roll i utformandet av kristen etik genom att den erbjuder ett unikt perspektiv på andra etiska källor och på Skriten själv. Detta perspektiv är baserat på uppenbarelse, och bör utformas utifrån den i Skriften centrala idén om imitatio Dei/Christi. Bibeln bör också erkännas som en unik källa till kristen etisk insikt. En medvetenhet om det omöjliga i att nå perfekt förståelse av Skriften öppnar dock upp för behovet av en dialog med andra källor till etisk insikt, källor såsom erfarenhet, tradition, och sekulärt förnuft, genom vilken dessa källor kan spela en roll i konstruktionen av kristen etik.Den kristna etiken angående samkönade sexuella handlingar menar slutligen att det måste göras en skarp skillnad mellan bra och dåliga handlingar av det slaget; de som utförs inom en kärleksfull relation, och de som inte utförs inom en sådan. De förstnämnda är försiktigt lovordade i egenskap av att resultera från en klart uppmuntrad homosocial kärlek, liksom till följd av positiva mänskliga erfarenheter, medan de senare är kraftfullt fördömda på grund av deras skadliga natur i relation till en av de, eller båda, inblandade
