Die stoommeule en bierbrouery op die terrein van Fort Drury, Bloemfontein, 1868-1920
No full textThe Fort Drury research project began in April 1998 when two of Bloemfontein's 70-year old landmarks, namely Fort Drury Mansions and King's Court, were demolished in favour of four new office buildings. The National Monuments Council gave permission for the two apartment buildings to be demolished on the condition that an archaeologist was appointed to search for any remains of the city's first fort, Fort Drury, which was built on the site in 1846. The archaeologist concerned asked the author to undertake the historical research of the site and its buildings. Although no trace of the structural remains of the stone and clay fort on the top of the hill was found during the archaeological excavations, the archival research brought some interesting and mainly unknown facts to light. At the start of the research project, only the existence of the fort on top of the hill above the fountain was known. Research would show that two other important structures - Bloemfontein's first steam mill and later on a brewery - stood on the same site, but behind the hillock and nearer the fountain. Until now, very little was known about these structures. However, this article sheds some light on the history of the steam mill and brewery on the Fort Drury site. The steam mill was erected in 1868. It worked with water from the fountain and served as a flour mill, saw mill, turning lathe and wool press until a few years before the Anglo Boer War. In c 1896 the mill was turned into a brewery where beer was brewed until 1920.

Species Distribution and in Vitro Antifungal Susceptibility of Oral Yeast Isolates from Tanzanian HIV-Infected Patients With Primary and Recurrent Oropharyngeal Candidiasis.
No full text\ud
In Tanzania, little is known on the species distribution and antifungal susceptibility profiles of yeast isolates from HIV-infected patients with primary and recurrent oropharyngeal candidiasis. A total of 296 clinical oral yeasts were isolated from 292 HIV-infected patients with oropharyngeal candidiasis at the Muhimbili National Hospital, Dar es Salaam, Tanzania. Identification of the yeasts was performed using standard phenotypic methods. Antifungal susceptibility to fluconazole, itraconazole, miconazole, clotrimazole, amphotericin B and nystatin was assessed using a broth microdilution format according to the guidelines of the Clinical and Laboratory Standard Institute (CLSI; M27-A2). Candida albicans was the most frequently isolated species from 250 (84.5%) patients followed by C. glabrata from 20 (6.8%) patients, and C. krusei from 10 (3.4%) patients. There was no observed significant difference in species distribution between patients with primary and recurrent oropharyngeal candidiasis, but isolates cultured from patients previously treated were significantly less susceptible to the azole compounds compared to those cultured from antifungal naïve patients. C. albicans was the most frequently isolated species from patients with oropharyngeal candidiasis. Oral yeast isolates from Tanzania had high level susceptibility to the antifungal agents tested. Recurrent oropharyngeal candidiasis and previous antifungal therapy significantly correlated with reduced susceptibility to azoles antifungal agents.\u

First-Year Students’ Experiences of ‘Transition as Induction’ at a South African University
Raymond Nkwenti Fru, Wiets Botes, Alan Felix, Felix Awung, Tiani Wepener, Richard Moloele
Abstract
The emergence of the global pandemic has had devastating effects on institutions of higher learning. In South Africa, many universities had to swiftly switch to online teaching and learning in a bid to mitigate the effects of the pandemic without considerable repercussion on the academic project. The paper investigates first-year undergraduate students’ experiences of induction as a critical phase of university transition at a South African university. The focus was to investigate how first-year undergraduate students transition into the unknown university environment as they come from various backgrounds. A case study research design was employed in the study. The population included first-year students across all schools in various areas of specialisation at the South African University. Given this population, a purposive sampling technique was employed in the study from which selected students to the tune of forty were interviewed. The findings revealed that the students had varying experiences of transition. Nuanced with the theory of resilience, these experiences were then interpreted following the constructions of deterioration, adaptation, and recovery. The study serves as valuable feedback on how South African universities can go about transforming their cultures, systems, and policies to better support first-year students during a phase of induction
Preliminary design of an ORC GP33 racing yacht.
No full textThe aim of the dissertation is to outline the preliminary design of an ORC GP33 class racing yacht.
The author is particularly experienced in one-design keelboat and fleet racing. This design aims to produce a sensible, easily built and competitive GP33 class racing
yacht.
The preliminary design was driven almost exclusively by the initial weight estimate, influencing all aspects of the design spiral. Wind analysis was carried out on the
proposed racing region and the yacht was refined for sailing in these conditions.
Whilst stability and reducing wetted surface area were key factors in optimising the boat during the iterations of the design process, from its inception the boat was to be light weight and aimed at being as fast as possible for the assumed wind conditions.
Velocity prediction was made extensive use of, for this project, to ascertain the optimal hull parameters, as well as comparing performance to an already built and proven GP33.
This project proposes an easily built, fast and relatively cheap entry in to Grand Prix
fleet racing
Opimisation techniques for the design of a DC-excited vernier reluctance machine operated as a synchronous condenser
No full textThesis (MEng)--Stellenbosch University, 2023.ENGLISH ABSRACT: With the growth in the renewable energy sector, and with power electronic devices failing to provide the required grid strength, there has been a renewed interest in the synchronous condenser industry. Synchronous condensers are used to provide rotational inertia, short circuit strength, low voltage ride through and reactive power compensation to the grid. However, synchronous condensers are also known for high operational losses and costly maintenance requirements. The DC-excited vernier reluctance machine was recently proposed as an alternative to address some disadvantages of conventional wound rotor synchronous condensers [1]. This study continues the research by focusing on the development of an optimisation technique that optimises the reactive power performance of the DC-excited vernier reluctance machine as a synchronous condenser for a fixed machine volume. An optimum selection criterion for a synchronous condenser from the optimisation Pareto front is proposed based on the relationship between the required reactive power and an efficiency indicator of reactive power per loss. As part of the optimisation, a technique is developed that estimates the core losses of the dc-excited vernier reluctance synchronous condenser within a single finite element solution. This technique is developed to reduce the computation time of the optimisation. Furthermore,
the performance of the optimised DC-excited vernier reluctance synchronous condenser is analysed using two finite element packages. The frozen permeability technique is adopted and used to calculate the inductance and performance parameters of the machine. In this thesis the author applies the optimisation technique to DC-excited vernier reluctance synchronous condensers with different volumetric sizes and kvar-ratings as part of a case study. As part of this case study, a 300 Mvar wound-field flux-switching machine is optimised with the newly developed optimisation technique and compared to a dc-excited vernier reluctance synchronous condenser of the same volumetric size. The author also includes a conventional four-pole synchronous condenser in the case study that compares
the reactive power per loss and per volume. These machines are then compared, by mainly considering their reactive power per loss and reactive power per volume. Finally, a 55 kvar DC-excited vernier reluctance synchronous condenser prototype is built as part of the study. This prototype is used for the experimental data validation of the simulated results.AFRIKAANSE OPSOMMING: Geen opsomming beskikbaar.Master

Acquisition integration framework for technology enterprise : the human factor
No full texttextAcquisitions are common in today’s business and people involved in acquisitions face challenges when they become part of this process. This thesis aims to provide an understanding of the human factors that determine the outcome of acquisition integration. Various frameworks exist in the literature that focuses on human and task integration as measures for success. In addition to these, the author explores an additional aspect, customer integration, as an important measure to determine overall integration success. Execution is the key to successful acquisition integration.
Employees of a technology company were surveyed to gauge their acquisition experiences over three past acquisitions. The survey was a limited targeted case study that focused on analytical value, rather than statistical value. The survey data is analyzed and aligned with the literature data to identify some possible best practices the technology company could follow in future acquisitions. The survey results are used to establish the implications for the company’s acquisition process and to help the development of a playbook for acquisition integration.Engineering Managemen
Exploring the relationship between inflation and unemployment in South Africa: A historical, theoretical, and empirical review
No full textJournal Article, Faculty of Economic and Management Sciences, Teaching & Learning-- North West UniversityThe paper investigates the relationship between inflation and unemployment in the South African setting, encompassing a comprehensive analysis of historical, theoretical, and empirical evidence. Existing literature surveys demonstrate that several studies have been conducted in multiple countries to ascertain the correlation between inflation and unemployment. The review incorporated the postulations of many economic schools of thought as they are applied to South Africa. The Phillips Curve was examined in accordance with the research purpose. The process involves gathering secondary data from reputable sources such as Statistics South Africa, the South African Reserve Bank, and other reliable secondary sources to analyse this relationship. The findings are presented using linear regression, tables, and figures. The study utilised annual inflation and unemployment data in South Africa spanning from 2000 to 2022 to elucidate the correlation between inflation and unemployment. The study discovered that the link was nonlinear and did not exhibit any meaningful association or correlation.Acknowledgement
