The liturgies of Guillaume Farel: their meaning and relevance

- Description: Relatively little study has been devoted to Guillaume Farel. Though a number of Biographies have been published, these were mainly devotional or inspirational. The only critical biography to have been published in modern times, and to which the author has made much reference, is that written by the 'FAREL COMMITTEE' to commemorate the fourth centenary of the reformation at Neuchȃtel. The comparative neglect suffered by Farel and his works is surprising in view of his role as pioneer of the reformation in French-speaking Churches. The spotlight has been held almost exclusively on the second generation reformer John Calvin. The paucity of material available may help explain why Farel has remained such an obscure figure. This dissertation does not attempt to bring to light the full scope of Farel's work. This still has to be done. Incidentally the author has been informed that. there are at present two American post-graduate students doing research on Farel at Neuchȃtel. This may hold a promise of further light on this significant father of the reformation. The author has limited himself here to an examination and evaluation of Farel's liturgical works. These were only a very small portion of his wide field of activity. The further study necessary to investigate the full influence of these liturgies on the development of reformed worship is only outlined here. In order to set the Farellian orders in their context, a certain amount of historical and doctrinal background has been given. This is by no means exhaustive as each service would justify a separate dissertation. An effort has been made to cut background down to a minimum and to bring out the main tendencies only so as to situate Farel in the development of the understanding of the Church 's worship.

The study of the potentiation of anticholinergic side effects of tricyclic antidepressives by female sex steroids

- Description: It has been recorded that women respond to tricyclic antidepressives with a greater incidence of anticholinergic side effects than men do, particularly women taking an exogenous source of oestrogen. The aim of this study was to investigate the influence that ethinyl oestradiol and Premarin© had on the metabolism of a number of tricyclic antidepressives, and also the influence they had on the binding ability of microsomes to imipramine. Rat hepatocyctes and microsomes were used. Detection techniques used were High Pressure Liquid Chromatography and Spectrophotometry respectively. In addition to these studies, a study of the anticholinergic activity of Nomifensine, tricyclic antidepressives and their derivatives was performed on a rat jujenum. Results conclusively showed that ethinyl oestradiol had a marked influence on the metabolism of the tricyclic antidepressives studied. Premarin© had Iittle, if any influence. However, both ethinyl oestradiol and Premarin© affected the binding of microsomes to imipramine, but ethinyl oestradiol had the greater effect. The parent compound in each case exhibited a higher pAZ value. Results indicate that a possible explanation for the increased anticholinergic side effect is due to an inhibition of the metabolism of the tricyclic antidepressives by oestrogen.

A reappraisal of the governorship of Sir Benjamin D'Urban at the Cape of Good Hope, 1834-1838

- Description: Preface: Sir Benjamin D'Urban only spent four years as Governor of the Cape Colony, yet to many people he is one of the most easily identifiable of all British Governors. The principal reason for this, it seems, is the continuing emphasis placed upon his short-lived settlement of the Colony's troublesome eastern frontier in 1835. The main objectives of this thesis have been to examine some of the most notable analyses of that settlement together with an attempt to remove D'Urban's governorship from the narrow and controversial confines imposed by his frontier policy. I have tried to place his governorship in the wider context of his day, examining the various controls upon him, and his overall role as Governor together with some of his administration's less well known but ultimately equally important aspects. In effect, I have tried to view D'Urban in 'the round '. The thesis makes no pretence at being a complete survey. Several important and possibly contributory aspects to a fuller understanding of D'Urban's Cape interlude - notably his ten years in various executive positions in the West Indies and British Guiana, and his period as commander-in-chief of the British army in Canada - were beyond the reach of anything more than a cursory review. Presumably there are documents relative to this period of D'Urban's life in the Archives in Montreal, Georgetown and London. D'Urban's reputation in South Africa continues to rest upon the short-lived system he established in 1835 and the great promise for future relations between black and white that many authors then and since saw in it, or alternately failed to see in it. With this in mind, and the realisation that 145 years and a succession of Governors, High Commissioners and Prime Ministers have passed since 1835, the following extract from the front page of The Daily Dispatch of 10 May, 1980, is revealing. It was reported that the Ciskei government demanded "all the land between the Kei and Fish Rivers, the Indian Ocean and the Stormberg Mountains to form the territory of an independent Ciskei ." The fundamental questions of to whom the land belongs and of how to establish a just modus vivendi with the Xhosa, which plagued both D'Urban's short administration and the Colonial Office for much of the Nineteenth Century are still with us today. Any analysis of his four year period as Governor of the Cape must necessarily be tempered by this realisation.

Blanching assessment was undertaken immediately after preparing the various dilutions and at 1 and 3 months thereafter. Few statistically significant differences were noted between any of the preparations tested indicating that the rate of release of betamethasone 17-valerate is relatively unaffected by dilution. All preparations were assayed by a stability indicating high pressure liquid chromatographic technique for corticosteroid content. A diminution in the content of betamethasone 17-valerate in the E45 dilution was found 14 months after preparation. All other formulations tested were found to comply with label claim specifications.

- Description: From introduction: The aim of this thesis is to describe and analyse the effects of labour migration on marriage and family life. The field material is from Burnshill, a village situated in the Keiskammahoek district in the Ciskei. Keiskammahoek is bounded on the East by the districts of King William's Town and Stutterheim, on the West and South by Middledrift and on the North by Cathcart. The inhabitants of Burnshill are overwhelmingly Xhosa and Mfengu (the main ethnic groups in the Ciskei) but also include a small proportion of people whose clans are of Mpondo and Thembu origin. This village has undergone extensive change. As we shall show later, it was settled de novo by the Mfengu and the Xhosa during the second half of the past century. This is one of the reasons why it lacks the homogeneity and continuity of cultural tradition which are predominant features of long-established communities.

This proved to be a formidable task. However, most of the material collected, including all the individual poems prescribed, was recorded in table form. This proved too bulky a system for comparative purposes and the field was narrowed to include only that English literature which had been prescribed for candidates writing Matriculation or Senior Certificate examinations on the higher grade as part of the English Language syllabus. From time to time, however, reference will be made in this thesis to prescriptions for the lower grades and for the lower standards.

Geological factors affecting tonnage-grade relationships in orebodies of the Zambian Copperbelt

- Identifier: vital:21151 , http://hdl.handle.net/10962/6617
- Description: The occurrence of a major metalliferous province in Zambia and Zaire is a reflection of geological processes operating in a specific environment during a particular period. The size of orebodies, their grade, mineralogy, beneficiation characteristics and therefore the amount of metal produced are all ultimately functions of the geology of the ores. This study is primarily concerned with the effect geology has on tonnage-grade relationships of ore in situ on the Zambian Copperbelt. Five major topics related to ore tonnage and grade are reviewed here: -behaviour of copper and cobalt in surficial environments. -geological setting and gross lithostratigraphic relationships of mineralization. -characteristics of known orebodies. -geological factors affecting mining and beneficiation of ore. -orebody limits and estimation of tonnage and grade. In addition, the historical background to the problems discussed here is briefly described, and some general aspects of the evaluation, mining and beneficiation of Copperbelt ores are considered in relation to metal production.

Review of carbonate hosted lead-zinc (copper) deposits and the geological factors affecting their shape, size and grade

- Language: English

- Identifier: vital:5028 , http://hdl.handle.net/10962/d1006903
- Description: From Introduction: For at least two centuries and a corresponding number of generations of geologists and miners there has been active argument concerning the origin of certain types of carbonate hosted mineral deposit. The characterization of the type itself was and still is debatable. Objections have been raised to grouping several examples under one heading because each has its individually distinctive features. ·This is especially applicable to the carbonate hosted lead-zinc "sedimentary" deposits. The type that will be discussed in the text to follow is composed chiefly of galena, sphalerite, barite and fluorite, with pyrite , marcasite and chalcopyrite as conspicuous accessory ore minerals. Exceptions to this general copper deficient characteristic displayed by the sedimentary carbonate-hosted lead-zinc deposits are the deposits at Tsumeb and Kombat, Namibia. These deposits are hosted by the carbonate sequence of the Otavi Shelf sediments, and copper, in the form of tennantite, chalcopyrite and bornite, is the major ore constituent. Calcite, aragonite, dolomite and quartz are the commonest nonmetallic gangue minerals but siderite and silica may also be present. In contrast with other lead and zinc sulphide (volcanogenic) deposits, those to be considered here seldom carry noteworthy amounts of silver or any other precious metals. Commonly the country rock is a carbonate; limestone or dolomite, but deposits in. sandstone, shale and conglomerate are not unknown. Characteristic features are ore bodies that extend parallel or nearly so with the bedding although many such deposits are partly, or completely developed along crosscutting fissures and breccias. Some observers regard these fissure fillings as evidence for a magmatic source of the metals, whereas others regard them as an indication of remobilization of ions, metals or minerals orginally present in low-grade stratiform deposits elsewhere in the stratigraphic succession.

Exceptions to this general copper deficient characteristic displayed by the sedimentary carbonate-hosted lead-zinc deposits are the deposits at Tsumeb and Kombat, Namibia. These deposits are hosted by the carbonate sequence of the Otavi Shelf sediments, and copper, in the form of tennantite, chalcopyrite and bornite, is the major ore constituent. Calcite, aragonite, dolomite and quartz are the commonest nonmetallic gangue minerals but siderite and silica may also be present. In contrast with other lead and zinc sulphide (volcanogenic) deposits, those to be considered here seldom carry noteworthy amounts of silver or any other precious metals. Commonly the country rock is a carbonate; limestone or dolomite, but deposits in. sandstone, shale and conglomerate are not unknown. Characteristic features are ore bodies that extend parallel or nearly so with the bedding although many such deposits are partly, or completely developed along crosscutting fissures and breccias. Some observers regard these fissure fillings as evidence for a magmatic source of the metals, whereas others regard them as an indication of remobilization of ions, metals or minerals orginally present in low-grade stratiform deposits elsewhere in the stratigraphic succession.

- Description: The blanching activities of Betnovate and Celestoderm-V lotions (betamethasone-17-valerate, 0,1%) and Diprosone lotion (betamethasone dipropionate, 0,55%) were determined by measuring their ability to cause blanching of human skin after topical application. Betnovate and Celestoderm-V lotions produced almost identical blanching profiles. Diprosone lotion displayed a statistically significant superior blanching acitivity over both Betnovate and Celestoderm-V lotions over the whole timespan of the trial.

A Piagetian programme of intervention: facilitation of conceptual change and cognitive growth
- Authors: Moore, Robert Soulsby

- Description: This research aims (within a strictly Piagetian framework) toward the development of a programme of intervention which will facilitate cognitive development, conceptual change and scientific literacy for those individuals who experience difficulty in coping with contemporary scientific and technological concepts. The research focuses specifically on the development of a diagnostic battery useful for realising a conceptual profile of the individual. This profile would indicate personal areas of functional interests that can be used creatively as a starting point for the facilitation of cognitive growth. The goal of such a programme is not the acceleration of cognitive growth, but rather the restoration of the individual to the mainstream of transactions in which the process of growth can flourish. The proposed facilitatory programme makes use of Piagetian tasks in a voluntary, individualist mode of instruction comparable to recently developed techniques of scientific education programmes. In brief, this research analyses three specific areas: 1) The development of a body of theory that can assist in the development of such a facilitatory programme, 2) The development of a diagnostic battery to provide insight into the individual's level of conceptual development, 3) The realization of certain guidelines for an instructional procedure whereby facilitation of growth can begin . The experiment takes the form of a pilot study of twenty four black and white subjects, exploring whether the battery of Piagetian tasks reveals a profile of conceptual development of the individual. Unique conceptual profiles were realized for all individuals, with evidence pointing towards the existence of a relationship between functional interests and the more advanced areas of the individual's conceptual development.

- Description: From preface: This study of the British settlers of 1820 in South Africa uses one party of emigrants as a unit of historical research. In unfolding their story, it attempts to discover how far the standard assumptions about the 1820 settlement are borne out by the historical facts. No systematic set of hypotheses for investigation was established in advance; instead, the structure of the thesis has been determined by the course of the narrative, and the main issues have emerged spontaneously as it has progressed. Although the chronology has been maintained as far as possible, the narrative itself does not follow an entirely straightforward course. The emigrant party of eighty-four men and their families under the leadership of John Bailie which is the subject of the study was officially subdivided five weeks after landing at Algoa Bay, and the dispersal of its members to the established towns of the colony began even sooner. At the end of the three-year period laid down as a residential qualification by Government, less than a third remained to claim land on the party's location in Albany.

My duty, therefore, is that of an interpreter of the situation. There is nothing academic about apartheid. What is there is the monstrous evil perpetuated through the genius of the Afrikaner-Broederbond and the Afrikaans Churches and to a lesser extent by the liberal white community within the confines of South Africa (Introduction, p. vii)

- Description: The plant communities of the Andries Vosloo Kudu Reserve (6493 ha.; Acocks's Valley Bushveld) are classified using the Braun-Blanquet phytosociological technique. A checklist of the flowering plants is presented. The flora of the reserve displays an affinity to five phytochoria (Capensis, Karoo-Namib, Sudano-Zambezian, Afro-montane and Indian Ocean Coastal Belt 1, of which the Karoo-Namib and Indian Ocean Coastal Belt are the most extensive. The flora of the Valley Bushveld is regarded as adequately conserved, but a recommendation is made to consolidate the study area with adjacent farms. A small herbarium, containing specimens of all species listed in the checklist, has been established. The climate of the study area is classified according to the Koppen classification as Cfa. Simultaneous air temperature recording at four separate localities demonstrated that differences exist between local ities of marginally different altitude, aspect and slope. The phenology of 51 plant species, recorded at monthly intervals over a continuous period of 478 days, is presented. These species are classified according to their response to air temperature and rainfall for the initiation of new growth, flowering and fruiting. Species exhibited a spectrum of responses ranging from endogenous to exogenous control over phenological events. , KMBT_363 , Adobe Acrobat 9.53 Paper Capture Plug-in
