The dissolved air flotation (DAF) has been used in drinking water treatment for its excellent algae and natural organic matter (NOM) removal. DAF drinking water treatability test are often conducted in a DAF jar test apparatus. Although, DAF jar test studies showed that they were able to predict NOM removals at full-scale facilities well, they have not always been successful in predicting the turbidity removals. One possible reason of the DAF jar test inaccuracy results could be associated to the small jar diameter, which may create wall effects. Therefore, the first two objectives of this research are: a) to develop and test a new, larger diameter and larger volume batch bench-scale dissolved air flotation system (LB-DAF) to better simulate turbidity removals in drinking water applications; b) to confirm these results by comparing the LB-DAF and full-scale DAF turbidity removals for two other source waters. The raw water characteristics of the three plants were quite different and the testing was performed at different times of the year. The development/optimization of the LB-DAF evaluated the impact of different variables (i.e., mixing intensity, water depth/tank diameter ratio, impeller shape, saturator pressure and recycle ratio). The results showed that the LB-DAF predicted well the full-scale DAF turbidity removals at three water treatment plants, and these predictions were better than those of DAF jar tests. For the LB-DAF design and operational variables evaluated had a limited impact on the turbidity removals. The LB-DAF predicted well DAF full-scale turbidity removals regardless of water temperature. This is an indication of the robustness of the DAF system. Ballasted sedimentation (BS) is a compact coagulation/flocculation and sedimentation process combination that has become very popular because it is very compact and because it can handle large variations in raw water turbidity and NOM. The literature survey did not initially identify studies on the BS treatment of algal impacted waters, for which DAF is considered particularly suitable. Thus, the third main objective of this dissertation was to compare the efficiency of BS with that conventional gravity settling (CGS), and that of DAF for the treatment of an algal impacted water via jar tests. These comparisons were performed at the Belleville Water Treatment Plant using Bay of Quinte water, one of the most eutrophic zones of Lake Ontario. Unfortunately, a change of weather prior to the testing resulted in raw water samples with relatively low concentrations of algae and cyanobacteria. The testing showed that DAF and BS had very similar NOM, cyanobacteria/algae (chlorophyll a and phycocyanin) removals.; however, the BS required microsand addition, polymer addition and a slightly higher alum dose. Only for turbidity removal the DAF was somewhat superior. It is suggested that these comparison experiments be repeated with waters that are more impacted by algae and cyanobacteria.

The purpose of this study was to evaluate how the BS.1770 Loudness Standard is affected by the amount of difference signal present in the signal being measured, and if this affection is different between the two playback systems Headphones and Loudspeakers. The study was restricted to rock music productions in a stereo format. The results obtained from the study might provide useful information to mixing and mastering engineers, as it evaluates the correlation between spatial information and subjective loudness. The study consisted of an active listening test, containing six stimuli with different Sum and Difference Ratio (SDR). The test was done in both headphones and loudspeakers, and the difference in volume as set by the subjects were noted. The results from the headphone version and the loudspeaker version were then compared in a paired t-test to see if there was a significant difference between the two formats. The results pointed to the factors of Playback System and SDR to have non- significant effect on the results. After analyzing the possible error sources, it became apparent that other factors had a far greater effect on the results. The results imply that the BS.1770 Loudness Standard can accurately measure the loudness of a given stereo rock music material, despite the fact that it does not consider the differences between the channels when conducting the measurement. Whether or not the effect being studied is significant in other conditions is not verified, due to the restrictions of the study. Further studies would be needed in order to verify the findings of this study, preferably with more attention to detail since there were apparent flaws in the method used.

This research assesses the use of scripture in tracts published in Swahili in East Africa. The use of tracts for the propagation of religion is introduced through the work of Tract Societies in Britain and the use of Christian tracts in overseas missions. Printing in Arabic and the propagation of Islam through tracts is surveyed. The historical use of tracts by Christians and Muslims in East Africa, and Swahili as a religious language, are examined. In 2000 and 2001, Christian and Muslim tracts in Swahili were purchased from particular locations in Kenya and Tanzania. Of these, sixteen tracts, eight by Christians and eight by Muslims, were selected. The tracts use passages from the Bible and/or the Qur’an mainly for outreach purposes. They are described and analysed and scriptures within them recorded. Eighteen Biblical and Qur’anic passages that appeared in more than one tract were chosen. These scriptures, together with the interpretations of them within the tracts, are translated, presented thematically, analysed and compared. The research found differences between Christian and Muslim use of the passages, noting that the approach of most tracts is polemical, thus raising concerns that they may increase misunderstandings between Christians and Muslims in East Africa.

The author of the Book of James names four exemplars in the course of his work. These serve specific functions within their individual contexts in the composition; Abraham and Rahab as exemplars of a vital active faith, Job as an exemplar of steadfast endurance, and Elijah as an exemplar of effective prayer. This thesis explores the wider stories of the exemplars in the Hebrew Bible, traces their development in elements of early Jewish tradition, and compares the author’s use of the exemplars with that of other New Testament writers. It argues that, the author of the Book of James uses the exemplars collectively as a means to encourage his messianic audience to remain faithful to God in the trials of everyday life until the imminent Parousia of the Lord. The four exemplars share three characteristics that will aid the audience in their daily struggles: they were all tested to the limit, yet demonstrated their whole-hearted commitment to God by remaining faithful to him; they were all outsiders who rejected the wisdom (values) of the world and they all faced their life-defining trials reliant on God rather than on other human beings.

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 thesis uses a practical-theological methodology to explore the theology and spirituality of „spiritual warfare‟ that developed in the charismatic renewal from the 1960s. Beginning with a study of twelve charismatic Anglican pioneers, a detailed case study then explores spiritual warfare praxis in a charismatic Anglican congregation. The ensuing theological reflection focuses on the ontology of evil, through dialogue with Nigel Wright, Amos Yong, and Gregory Boyd, as well as Karl Barth and Walter Wink. The thesis argues for a positive ontology for evil powers, based on a charismatic hermeneutic of biblical texts; on the grounds that Jesus treated Satan and demons as real spiritual entities, the Pauline epistles refer to real evil spiritual powers in the heavenly realms, and charismatic experience supports this ontology. Such powers are in malevolent and wilful rebellion against God, deriving from a corrupted fallen angelic nature. A Trinitarian model of theological praxis is presented, focused on responding to the goodness of God in repentance; renewing faith in the believer‟s identity in Christ and His victory upon the cross; and resisting the devil in the power of the Spirit. This model emphasizes personal responsibility, helps bring freedom from fear, and re-connects with Anglican baptismal liturgy.

This thesis presents measurements of the branching fractions of the charmless baryonic decays B(s) → p anti-p h+ h'-, where h(') denotes a kaon or a pion. Three new modes (B → p anti-p pi+ pi-, Bs → p anti-p K+ K- and Bs → p anti-p K+(-) pi-(+)) are observed for the first time and evidence is found for a fourth (B → p anti-p K+ K-). The inclusive branching fraction of B → p anti-p K+(-) pi-(+) is measured for the first time and the upper limit is set on the branching fraction of the Bs → p anti-p pi+ pi- decay. This represents the first observation of four-body charmless baryonic decays of a Bs meson and one of the first observations of baryonic Bs decays. The implementation of the real-time alignment of LHCb's vertex detector is also described. The novel real-time alignment and calibration strategy adopted by LHCb is essential to allow more stable data taking conditions and an optimal 'offline-quality' reconstruction to be performed at the trigger level, ensuring more efficient trigger selections and the possibility to perform physics analyses directly on the trigger output.

The photosynthetic water splitting reaction performed in green plants, algae and cyanobacteria is perhaps one of the most important reactions on the planet. The reaction is catalysed by a tetranuclear manganese cluster that is driven by sunlight and as such has received a high degree of interest in the context of solar fuels research. Due to the intricacy of the bioinorganic systems, the molecular mechanisms of the reactions are unknown and structural elucidation of the active sites is complicated. Computational techniques can provide considerable support in the analysis and interpretation of the complex EPR spectra of such biological systems. In this work, the molecular and electronic structures of several multinuclear manganese containing bioinorganic systems are investigated using BS-DFT. A particular focus of this work is the provision of high quality calculated EPR parameters yielding structural and mechanistic insight. In the first results chapter, the MnIIIMnIV superoxidised state of manganese catalase as well as azide inhibited manganese catalase is studied. Several variants are proposed and analysed on the basis of their calculated EPR parameters. The results presented in this chapter offer a new interpretation of previous experimental assignments. Chapter 6 features investigations on the S2 state of the Oxygen Evolving Complex of Photosystem II. In this chapter both the native OEC as well as the strontium substituted OEC are studied, in order to investigate how replacement of the calcium ion affects the structure of the OEC. The final results chapter presents calculations on the split signal S2Yz dot radical formed on the transition from the S2 to S3 state, as well as studying the S3 state. The calculation of various EPR hyperfine couplings and their comparison with available experimental data has provided key insights into the electronic structure of the OEC.

In the ancient world, impairment was common knowledge: archaeological and written material demonstrate that people with impairments were included in society. Impairment was well understood and, in the rhetorical dynamic between author and reader, it was imaginatively used. The Early Church, for instance, developed established impairment themes in order to articulate, explain, and demonstrate central conceptions and experiences of divine activity and human discipleship. Peculiar to the modern era has been the disappearance of people living impairment from mainstream experience. As a result of this culturally-shaped process, modern presuppositions about impairment have emerged that are experienced by people living impairment as profoundly negative and disabling. Modern biblical interpretation both reflects and reinforces these presuppositions, overlooking the wide range of uses of impairment in ancient texts, and causing alienation and damage to people living impairment. To read texts of the Bible informed by an investigation of the perspectives on impairment in the ancient world presents a challenge in two respects. It identifies the inadequacies and impoverishment of uncritical modern interpretation of the biblical impairment texts. It also stimulates new and fresh liberatory readings, which reclaim as the proper focus for the interpretation of these texts the experience of lived impairment.

This thesis is a diachronic investigation of Lewi Pethrus’ ecclesiological thought from 1911 to 1974. The research employs Roger Haight’s transdenominational ecclesiology as its methodological framework. Since Haight’s methodology is based on a concrete ecclesiological method that emphasises the importance of a historical consciousness in ecclesiology, the study particularly focuses on the formative contexts that shaped Pethrus’ ecclesiology. The emphasis on formative contexts not only explains why certain ecclesiological concepts arose at particular points in Pethrus’ life but also clarifies why concepts were abandoned or developed over time. A vital part of Haight’s methodology is also to examine the religious values that remain constant and significantly form ecclesiological views. The thesis argues that Pethrus’ ecclesiology is shaped by a Pentecostal form of spirituality that has ‘loving Christ and loving neighbour’ as its core values. The combination of a Pentecostal form of spirituality and formative contexts is what makes Pethrus’ ecclesiology ‘Pentecostal’ and gives it its inner logic. The thesis concludes by taking this inner logic of Pethrus’ ecclesiology and hypothetically applying it to a global setting. The result is a contribution toward a transdenominational Pentecostal ecclesiology that has important implications for any attempt to construct a global Pentecostal ecclesiology.
