The rapid post-Independence development of the city of Windhoek, Namibia; and the ensuing destruction of a substantial number of German colonial buildings in the capital city, prompted speculation as to why these buildings are inadequately protected as heritage – and whether they are, in fact, considered to be heritage. The study explores the issues pertaining to the presence of German colonial architecture, as artefacts of the German colonial period, within the postcolonial context of Windhoek. The trauma and pain of the Namibian War and genocide (1904 – 1908) are recurring themes in the body of literature on postcolonial Namibia; and this informs a wider discourse on memory. Memory is found to play a crucial role in evoking a sense of both individual and shared ownership, through its capacity to create meaning, which can in turn ascribe value to a place. Memory is also dependent on visual cues for its continued existence, which suggests the importance of colonial architecture as a material prompt to sustain memory. The research therefore investigates the memories and multiple meanings attributable to colonial architecture in this plural society, and how these meanings can be created, or possibly reinvented, through the continued use of these buildings. The study is based on an assessment of three halls in Windhoek – the Grüner Kranz Hall (1906), the Kaiserkrone Hall (1909), and the Turnhalle (1909; 1912), all designed by the German architect Otto Busch – which illustrates in part, the need for the development of historical building surveys that assess the social values and significances of these contested spaces; and moreover, the potential that these spaces have to support memory work through their continued use.

The ignition of a solid is an inherently complex phenomenon influenced by heat and mass transport mechanisms that are, even to this day, not understood in entirety. In order to use ignition data in meaningful engineering application, significant simplifications have been made to the theory of ignition. The most common way to classify ignition is the use of material specific parameters such as such as ignition temperature (Tig) and the critical heat flux for ignition (CHF). These parameters are determined through standardized testing of solid materials – however, the results of these tests are generally used in applications different from the environments in which these parameters were actually determined. Generally, ignition temperature and critical heat flux are used as material properties and are presented readily in sources such as the SFPE Handbook. However, these parameters are not truly material properties; each are inherently affected by the environment in which they are tested. Ignition parameters are therefore system dependent, tied to the conditions in which the parameters are determined. Previous work has demonstrated that ignition parameters (such as Tig or CHF) for the same material can vary depending on whether the sample is tested in a vertical or horizontal orientation. While the results are clear, the implications this may have on the use of ignition data remains uncertain. This work outlines the fundamental theory of ignition as well as a review of studies related to orientation. The aim of this study it to analyze the influence of sample orientation on ignition parameters. All experimental work in this study was conducted using cast black polymethyl methacrylate (PMMA or commonly referred to as acrylic). This study explores ignition parameters for PMMA in various orientations and develops a methodology through which orientation can be incorporated into existing ignition theory. An additional study was also conducted to explore the statistical significance of current flammability test methodologies. Ultimately, this study outlines the problem of the system dependency of ignition and provides commentary on the use of ignition data in engineering applications.

With the current upsurge of a technological era, there is an underlying global threat to the cultural development of theatre, especially opera. Therefore, there is a need for a paradigm shift that will re-imagine and transcend opera into the 21st century. Site-specific opera merges the potential of theatrical entertainment and the value of an existing site. Both the location and the performance have the ability to remove the audience from their lives and submerge them in a fantasy or created reality. With the focal approach being the interpretation of the Magic Flute Opera at a site-specific location, a concept of cultural heritage awareness is revealed. With this in mind, the preservation extends into a consideration of the existing site. The site, Fort Daspoortrand, is currently in a state of physical degradation, and the decay of heritage and cultural fabric is prominent. Thus, the potential for preservation and cultural celebration arises. It is proposed that through a site-specific opera performance of William Kentridge’s adaptation of The Magic Flute by Mozart, a sense of wareness can be created for both the site and a South African interpretation of opera. The opera will catalyse the awareness of the site, and the scenography will act as a vehicle to bring site and opera together in a visual and spatial experience. Through the merging of opera and site, the heritage and cultural significance of both entities will be explored, allowing the opportunity for life to be breathed back into both the fort and opera in general. The design intention of this project is to bring awareness to the existing fabric of the site, as well as the dramatic opportunities that the site naturally presents. In this way, the physical and cultural decay of both Fort Daspoortrand and opera are brought to the public’s attention. The intention in this creation of site awareness is to promote an afterlife for the site, by exposing its character in an attempt to ignite future development at the site once the opera has finished. Through combining opera and site, the audience will be exposed to the beauty of the site and the cultural richness of opera simultaneously. The temporary design intervention aims to strategically link the themes of The Magic Flute with the characteristics of the site to explore the relationship between narrative, fort and opera. Emphasis is placed on how to take the audience on a winding and intertwining journey of the site during the performance of the opera adaptation. The fluidity and natural progression of the audience through the site will ultimately create a reflective and emotive understanding of The Magic Flute’s theme of the journey from darkness to light. / Mini-dissertation Mint(Prof)--University of Pretoria, 2018. / Architecture / MInt(Prof) / Unrestricted

Research shows that early childhood interventions with fidelity to Montessori model generate learner’s outcomes that outperform the traditional model. The evidence is confirmed in developed and in developing countries. This formative evaluation reports the results of a Montessori model in implementation in township of Mfuleni, located in Cape Town, South Africa. Providing insights into the functioning of the programme, the evaluation confirms that the roll out of the Montessori model is still underway which may explain the reason of the learners not outperforming the comparison group.

Granulocyte colony-stimulating factor (GCSF) is currently the most widely used cytokine for stem cell mobilization. There are few studies suggesting GCSF administration may induce activation of both coagulation and endothelial cells that could favor the developing of thrombotic events. We report a 58-year-old female with vasculitis and renal impairment. She was found to have an underlying monoclonal gammopathy of unknown significance (MGUS). The monoclonal protein was felt to play a role in her underlying renal disease and peripheral neuropathy. She was considered a candidate for peripheral blood stem cell transplantation to manage the monoclonal protein. During stem cell mobilization with GCSF, she developed worsening of anemia; thrombocytopenia and worsening of renal function. She was diagnosed with thrombotic microangiopathy (TMA) which was successfully treated with therapeutic plasma exchange and rituximab. It is possible that GCSF may have directly (activating endothelial cells) or indirectly (activation of underlying autoimmune disorder) contributed to TMA in this patient.

The depauperate fauna of Newfoundland provides a limited prey base for marten. Only two small mammal prey species, Microtus pennsylvanicus and Sorex cinereus, were found in any abundance in the old-growth forests of the study area. Of these two, Microtus displayed population fluctuations typical of most microtines. Analysis of marten scats indicated that Microtus is a very important prey item to the marten with other food. items being of lesser importance particularly when Microtus are abundant. Trapping in various habitats indicated that Sorex densities were three to five times higher in logged areas compared to uncut areas. Unfortunately, the effects of logging on Microtus could not be determined directly from this study. Microtus numbers declined drastically in the spring of 1987, apparently independently of logging operations. Microtus numbers dropped from a density of 25.0 per hectare in the spring of 1986 to virtually zero in the spring of 1987. This reduction may be linked to an outbreak of viral encephalitus in the marten population in the fall of 1986. Marten (Martes arnericana) prefer mature coniferous and mixed forests and utilize regenerating cutovers minimally. The reasons for this are unclear, although prey abundance and availability may be involved. In this study, Sorex were more abundance in regenerating cutovers and the literature suggests that Microtus are also more abundant in these areas. This would seem to suggest that prey abundance above certain threshold densities is not critical to marten habitat selection. However, prey availability may play a more important role. Although prey species may be more abundance in logged areas, prey availability may be reduced.
