A viscosidade e a massa específica do B100 são propriedades físicas críticas relativas à sua aplicabilidade em motores diesel de injeção direta devido a: a) a temperaturas baixas o B100 torna-se viscoso, podendo cristalizar, causando dificuldades ao escoamento no motor; b) um aumento na viscosidade do B100 geralmente afeta o processo de atomização propiciando a ocorrência de reações competitivas, como combustão incompleta e polimerização. A viscosidade, bem como a massa específica do B100 e suas Misturas BX dependem diretamente da temperatura, comportamento semelhante ao do diesel, isto é, diminui com a temperatura de forma exponencial no caso de viscosidade e decresce de forma linear para massa específica. Por outro lado, a viscosidade e a massa específica destes combustíveis aumenta com o comprimento da cadeia e grau de saturação dos FAMEs. Este trabalho visa investigar o comportamento reológico do B100 e suas Misturas BX puras (B5/B10/B20/B30/B40/B50) e aquelas aditivadas com triacetina (Misturas B5-T/B10-T/B20-T/B30-T/B40-T/B50-T), investigados na faixa de temperatura de -2 a 90ºC visando uso nas regiões de temperaturas moderadas. modelos empíricos e semi-empíricos da literatura para viscosidade cinemática e massa específica em função da temperatura e da fração volumétrica do B100 presente na mistura foram avaliados quanto à sua capacidade preditiva, estabelecendo comparações entre eles e os modelos clássicos como o de Liew para massa específica e o de Andrade da viscosidade. O comportamento reológico, a viscosidade dinâmica e a massa específica desses combustíveis foram obtidos usando-se um reômetro do tipo Searle, método que associa dados oriundos da reometria ao modelo matemático para a viscosidade aparente dos fluidos da potência e densímetro digital, respectivamente. O valor da viscosidade cinemática foi obtido utilizando o conceito de viscosidade aparente para fluidos newtonianos, através do quociente entre os valores obtidos para viscosidade dinâmica oriundos da reometria e os valores da massa específica medidos experimentalmente. As propriedades de escoamento a frio de tais combustíveis (Pontos de névoa (PN), de fluidez (PF) e de entupimento de filtro a frio (CFPP)) foram obtidos através dos Mini Pour Point/Cloud Point Tester e CFPP tester. O aumento da fração volumétrica do B100 presente na mistura, modificou as propriedades de escoamento a frio dos combustíveis avaliados. O CFPP dos diversos combustíveis foi alterado de forma discreta. A adição da triacetina teve uma ação discreta quanto à diminuição do PN, porém, atuou de forma mais efetiva sobre o PF desses combustíveis. Os B100, diesel e Misturas BX e Misturas BX-T comportaram-se como Fluidos Newtonianos (FN) e Fluidos Não-Newtonianos independente do tempo (FNNIT) – Pseudoplástico – a 10≤ T≤ 90º C e -2 ≤ T ≤ 10º C, respectivamente. Os Modelos de Ramirez-Verduzco et al. (2012) e Tate e Allen Modificado apresentaram menor incerteza quanto aos dados preditos com erros associados inferiores a 5%, para massa especifica e viscosidade cinemática, respectivamente. A seleção dos Modelos mais apropriados para prever a viscosidade cinemática e massa específica dos B100 e Misturas BX foram avaliados através de análise estatística: a) Desvio Médio Absoluto; b) Análise de Resíduos e; c) Qui-quadrado, os respectivos algorítmos foram implementados no MATLAB.

Thus, the aim of this study was to propose the use of an inexpensive, easy to perform analytical method suitable for quantification and able to be adopted for the quality control of BX mixes in fuel distributors, which are required to ensure the correct percentage of the mixture and, unlike gas stations, have access to diesel oil and biodiesel originally used for producing the mixture BX. This is required to ensure the correct percentage of the mixture because unlike the gas stations, they have access to the diesel and biodiesel originally used for producing the mixture BX. Five different techniques for quantifying the biodiesel content were tested: points of fog and fluidity, differential scanning calorimetry, fluorescence in the ultraviolet to determine the sulfur content and specific mass at 20 °C. Diesel type A and biodiesel samples used were characterized by physicochemical parameters in accordance with present regulations. Among these techniques, only the assay of specific gravity at 20 ºC showed suitable linearity and repeatability, independent of the kind of diesel fuel used. A comparison was also performed between the results obtained with the method adopted by the ANP, which is based on infrared spectroscopy. The results showed that there is no statistical difference between the methods of FTIR and determination of density at 20 ºC, showing that this technique can be applied to quantify the biodiesel content in diesel fuel by fuel distributors. / Atualmente, no Brasil, todo óleo diesel disponível ao consumidor tem o percentual mínimo obrigatório de biodiesel de acordo com a lei vigente, tornando essencial o controle analítico do teor de biodiesel na mistura por razões de ordem técnica e legal. Assim, o objetivo deste trabalho foi propor o uso de metodologias analíticas de baixo custo, fácil execução e quantificação adequada, capazes de serem adotadas para o controle de qualidade de misturas BX em distribuidoras de combustíveis, que são obrigadas a garantir os percentuais corretos da mistura e que, ao contrário dos postos revendedores, possuem o acesso ao óleo diesel e ao biodiesel originariamente utilizado para produção da mistura BX. Foram testadas cinco técnicas diferentes para a quantificação do teor de biodiesel, sendo elas: os pontos de névoa e fluidez, a calorimetria exploratória diferencial, a fluorescência no ultravioleta para determinação do teor de enxofre e a massa específica a 20°C. As amostras de óleo diesel A e biodiesel utilizadas foram caracterizadas mediante os parâmetros físico-químicos e estes estavam em conformidade com as regulamentações vigentes. Dentre essas técnicas somente a análise de massa específica a 20°C apresentou tanto linearidade quanto repetitividade adequadas, independentes do tipo de óleo diesel utilizado. Foi realizada também uma comparação entre os resultados obtidos com o método baseado no uso da espectroscopia na região do infravermelho (FTIR). Os resultados obtidos mostraram que não há diferença estatística entre os métodos de FTIR e de determinação da massa específica a 20oC, mostrando que esta técnica é capaz de ser aplicada, em distribuidoras de combustíveis, à quantificação do teor de biodiesel em misturas BX.

Foucault’s concepts of Pastoral power and “governmentality” have led to the development of the London school of “governmentalists” (McKinlay and Pezet 2010). However, extant literature on governmentality drawn from this school of thought has undertaken an analytics of power centred on the deployment of governmental forms of power at the State level, not taking into consideration another entity that emerged after modernity, the modern enterprise, and not going beyond the 19th century, thereby trapping “governmentality” studies inside their own modern discourse. Following Foucault’s established relation between Pastoral power and “governmentality”, this thesis analyses the form of organising deployed by an organisation that emerged in the 16th century, apparently being able to survive into modernity without adopting modern managerial business categories. This organisation is the Society of Jesus, commonly known as the Jesuits. The first part of this thesis will analyse the relevance of the Society of Jesus for organisational studies and will show how modern business categories fail to explain its structural resilience. The second part of the thesis introduces Pastoral power as a possible explanation for the apparent structural resilience of the Society of Jesus. Following this line of reasoning, and after having established an analytics of power as a possible methodological framework, the Society of Jesus’ “organising practices” will be presented, leading to the conclusion that this entity, having emerged at the cornerstone of modernity, deployed practices that represent a significant shift when compared with previous Pastoral forms of organising. The fact that the Society of Jesus clearly intended to deploy practices for the conduction of geographicallydispersed individuals leads to the conclusion that it deployed a “protogovernmental” form of power, and that the rationality underpinning its practices, although not entirely modern, is clearly at the cornerstone of modernity and can therefore be enlightening to an understanding of how modern managerial categories might have emerged.

The notion of prophecy is a Leitmotiv, both in Scripture and in the Church. However, the popular form of prophecy that is witnessed in the Church today is the charismatic prophecy manifestations in the Pentecostal- charismatic movement. Although the latter is now billed as the fastest growing Christian movement in church history, and has brought to the fore the biblical notion of the charisms of the Holy Spirit, the subject of charismatic prophecy has received limited attention in Pentecostal studies. There is therefore a gap in knowledge. The present study is an attempt to address the lacuna; it is an empirical-biblical investigation of the nature and significance of prophecy in the Pentecostal- charismatic experience. The study presents a particular thesis: that charismatic prophecy, as observed in Pentecostal- charismatic congregational settings in the African context, is sacramental in its nature and parakletic in its functional significance. Thus, the charismatic prophecy experience is viewed as an intense moment of a participatory interface between the divine Spirit and the human spirit in which the divine Spirit infuses the human conscious dimension with revelatory impulses. The experience is parakletic in the sense that it edifies, encourages, and comforts the church in congregational settings.

This dissertation argues that a major factor in Pentecostalism's rapid world-wide growth was the emergence of a strong literary, as distinct from oral, tradition. From its earliest days the movement gave birth to a plethora of publications and publishing houses, mostly operating by faith, that proved highly successful in disseminating the distinctive tenets of the movement across the globe. The first part of this work outlines the social, historical and religious background to the movement in the USA and Britain, and highlights the distinctive doctrines and practices of Pentecostalism. The second section examines the emergence of Pentecostal publishing movements and their products in the USA, especially the role played by the prototypical magazine of W. J. Seymour, The Apostolic Faith. The third and major part of this dissertation is a detailed case study of the earliest, and most influential, Pentecostal magazine published in Britain, Confidence. The crucial role that this journal and its editor, A. A. Boddy, played in formulating and propagating the beliefs and practices of the nascent movement is critically examined, together with an assessment of its contribution to wider issues of religious life and thought in Britain. Areas of subsequent influence in the development of historic Pentecostalism and its contemporary offshoots are also discussed

In the contemporary world, wars, violence and injustice never seem to end. In an attempt to replace this culture of violence with a culture of peace, peace education attempts to raise awareness of non-violent and constructive means of dealing with conflicts, and to promote necessary skills, knowledge, attitudes and values. This research aims to gain insight into the reality of the current practice of peace education in schools in relatively stable countries. While a school is one of the places where children learn values, attitudes and behaviour, schooling is often criticised for maintaining and reinforcing different forms of violence, including physical violence and inequality. This study explores theoretical and practical aspects of peace education and key issues relevant to these aspects, including its place in schooling. The empirical study investigates a peace education organisation in the UK, West Midlands Quaker Peace Education Project (WMQPEP) and one of its projects in a primary school. WMQPEP particularly focuses on interpersonal skills to build peaceful relationships and raise self-esteem. The overall research provides understanding of the principles and practice of peace education as well as its impact, and identifies some factors which can either promote or undermine effective peace education in schools.

This study seeks to develop a more practical and praxis-driven approach to Dalit Theology and its engagement with grassroots Dalit Christians. Dalit Theology is contextual and liberative. It emerged as a counter to Indian Christian theology, which ignored the caste affected life experience of Dalits, who form the majority in the Indian church. It aims to go beyond the merely spiritual in seeking to empower Dalit people and transform society. However, the well reflected and articulated liberational theological themes of Dalit Theology seem to remain mostly within academia and the ecclesia. They have not adequately engaged with grass roots Dalit Christians who face severe discrimination and constant struggle against caste oppression. Therefore, this study is an attempt to analyse the status and potentials of Dalit Theology among grass roots Dalit Christians as a motivational force and to offer a methodological framework to enlarge Dalit Theology as a Practical theology of liberation. The construction of Dalit Theology as a Practical theology of praxis among the grass roots hopes to facilitate the process of bringing about change in their personal life and the formation of a transformed society for both Dalits and non-Dalits to lead a caste-free life.

The issues raised by the phenomenon of homosexuality among the Shona are so complex in their nature. The widely held assumptions are that firstly, there is no place for gays and lesbian within the Shona culture and secondly, God Forbids. To justify these claims they point to prevalent socio-cultural as well as ecclesiastical intermediary systems that serve as authorities to enforce and monitor specific rules of conduct and moral goals. The study explores these conventional notions and attempts to establish the reality in which these moral actions are carried out. It marks the beginning of the work of demystification and deconstruction of various existing theories and theologies of sexuality. By scanning through the intricate socio-cultural and ecclesiastical structures the study seeks to identify the place of homosexuality among the Shona and discuss the paradoxes and contradictions presented by the Church‟s approach. This study is an analysis of the underlying issues in regards to homosexuality among the Shona. Such an analysis helps in identifying and developing contextual sexual theological approaches.

This thesis is a study of the literary representation of St Margaret of Scotland in England and Scotland from the eleventh to the fifteenth century. Drawing both on existing developments made towards the understanding of the historical Margaret - and other medieval queens - and on advances in the wider theoretical field of queenship studies and feminist scholarship, it demonstrates the usefulness of reading the textual representation of Margaret as a reflection of contemporary ideas about queens and queenship in England and Scotland across the five centuries it covers. It identifies two key strands in the literary representation of Margaret - Margaret as dynastic mother and Margaret as ideal queen - and reveals how these were used both individually and together on both sides of the Anglo-Scottish border. This thesis demonstrates both that Margaret is something of a lightning-rod for ideas of good queenship and Scottish independent sovereignty, and that these ideas exist in symbiosis with her sanctity. This thesis ends with a consideration of how my literary analysis of the textual representation of Margaret might be used as a case-study to further understanding of the literary representations of other medieval queens.

This Practical Theological thesis examines the uses, understandings, and attitudes toward the rite of Christian Initiation (variously known as 'baptism' or 'christening') in the Church of England, contrasting the experiences of churchgoers and clergy with non-regular churchgoers and demonstrating its pivotal role in ecclesiastical boundary drawing. It develops a critical conversation between ecclesiology, theology, and the assumptions of ordinary people, revealed in their language when discussing the rite. Corpus based methods are used to explore naturally-occurring language in various corpora from a variety of genres, from 1500 to the present day. It concludes that there are significant linguistic differences between clergy/regular churchgoers and non-regular churchgoers and that the roots of this split go back to before Reformation times. Non-regular churchgoers’ use of language to describe this rite is more varied than that of churchgoers, who rarely used the word 'christening' nor figurative uses of these words. Non-regular churchgoers attached great social importance to the rite, but this was little understood by clergy and regular churchgoers. The Church would benefit from understanding and appreciating these different perspectives, both to enrich their own experience of Christian Initiation, and to allow more sympathetic pastoral care for those requesting the rite for their children.
