Contemporary architecture has failed to engage the rich culture of planar and spatial transformations of historical Muslim architecture, often relegating it to a form of naive pastiche or, at best, to the realm of historical reconstruction. In this project we make use of current digital technologies in an attempt to revisit and reinterpret, in modern terms, the geometric structure of patterns embedded in the historic Islamic architecture of Iran. The original contribution of this project lies in extending traditional two dimensional tiling patterns into a dynamic three dimensional state with the help of computational tools. The analogy to the classical Persian carpet as well as mobile character of design can also be seen as original. The notion of ‘transparency’ and ‘dynamism’ are interpreted using Autodesk’s Maya and Bentley’s Generative Components software. This report illustrates initial explorations and outlines future possibilities. In the past architects of the country were responsible for making the enclosure heaven-like while it was carpet weavers’ job to make the floor heaven-like. In this project as a symbolic approach, carpet and weaving becomes both the enclosure and the floor to define both floor and roof and symbolize the new approach through which we as architects use other disciplines and new tools such as new software to learn and shape the space and discover new vocabulary for a contemporary and local architecture for Iran. / Applied Science, Faculty of / Architecture and Landscape Architecture (SALA), School of / Graduate

Magister Scientiae Dentium - MSc(Dent) / A qualitative study was carried out to assess the role of traditional healers in oral health care in Kwa-Zulu Natal province, South Africa. The aim and objectives of the study were to assess the oral care knowledge and practices among traditional healers, to determine the extent to which traditional healers can diagnose oral conditions and how they could be used in the provision of primary health care and prevention of the spread of HIV infection. Another objective was to use the information collected to serve as a guide for collaborative oral disease prevention programme development.Three categories of traditional healers were identified in the sample: Isangomas, Nyangas and Umthandezelis. The average age of the sample was 45 years and the majority was female. Most healers were in training for between eight months and ten years. All traditional healers reported seeing patients with oral diseases and 93% reported that they referred patients elsewhere for additional help. All healers treated their patients with natural remedies. Seventy three per cent of the sample reported that they treated patients with HIV/AIDS. Less than 30% of the sample knew that AIDS was caused by a virus and 47% reported being ‘told’ by the ancestors whether an oral disease was HIV/AIDS.In this study traditional healers were shown a series of ten photographs of common oral diseases and oral HIV lesions and asked to identify as many lesions as possible. Following basic training and education about the causes and diagnostic features of the lesions, 100% of traditional healers were then able to identify aphthous ulcers, 80% Kaposi's sarcoma and 73% could recognize cancer of the tongue. These results showed that given proper education, traditional healers could play an important role in early detection of not only the common oral diseases but also the oral manifestations of HIV/AIDS. In addition, most traditional healers are skilled in interpersonal relations and if provided with the correct information they could be very effective as AIDS councilors.The traditional healers demonstrated good knowledge of the transmission, risk groups and prevention strategies for HIV/AIDS and they could serve as an important resource of information and should be incorporated in community based AIDS prevention and other programmes. / South Africa

Magister Legum - LLM / This thesis aimed to explore the various legislative provisions that have affected traditional health practice in South Africa. The discussion is limited to the period dating from 1891 to 2004. The relevance of this period is that during the 19th and early 20th centuries traditional healing has gone through some turmoil as the governments of that period promulgated legislation, which curtailed the practice of traditional healing. This study focused on the art of traditional healing in a legislative context. / South Africa

In Namibia, Omashikwa traditional fermented buttermilk made with the root of Omunkunzi (Boscia albitrunca) tree by local farmers is one of the most important rural food products. It provides nutrition, jobs and generates income for food security for the community. As a traditional fermented product, it is unusual as it has a viscous consistency and low syneresis. However, the quality of Omashikwa is inconsistent and is characterized by high acid taste, low pH, rancid flavour, root taste and smell and contains filth. In this research, the production process of Omashikwa, physico-chemical properties of the traditional and laboratory prepared Omashikwa and the role of the root of B. albitrunca tree in Omashikwa, viscosity, syneresis, microbiology and sensory properties were studied and compared in order to improve the quality of Omashikwa for wider community use and for poverty alleviation. Omashikwa was found to have a protein content of about 3.3%, fat 1.6%, moisture 90%, lactose 4.6%, ash 0.7%, total solids 8.7%, lactic acid 0.9% and a pH of 3.3 The quality of traditionally processed Omashikwa (TO) was compared with the laboratory processed Omashikwa (LO), which was made without the root. Traditional fermentation was carried out with raw milk and under rural conditions. After fermentation the milk was agitated vigorously to churn into butter, whereas LO was made with pasteurized (65ºC/30 min) and filtered milk, and cream was scooped off after fermentation instead of churning. LO had a significantly (p < 0.05) higher pH (4.44) compared to traditional Omashikwa (pH 3.25), lower acidity (0.68%) compared to 0.92% of TO. Fat content was higher in LO (2.44% fat) compared to 1.56% fat in TO. LO was free from filth and had higher viscosity (2.98 Pa.s) compared to 2.54 Pa.s and lower syneresis (14.4ml/24 ml) compared to 19.6ml/24ml of TO. It was found that extract from B. albitrunca root showed a low pH of 4.7 and exhibited bacterial inhibition properties on Total Plate Count Agar ring test. The root appear to specifically inhibit Escherichi coli, Staphylococcus aureus and Clostridium species. It also had a high content of soluble carbohydrates (hydrocolloids or gum) (19.4%). Significant difference (p < 0.05) in total aerobic counts was observed in TO of 6.62 log cfu/g compared to 8.62 log cfu/g of LO and lower lactic acid bacterial counts, 6.58 log cfu/g compared to 7.87 log cfu/g of LO. Probably the most affected microorganisms in TO were the non acid formers, as lower pH of TO and inhibitory compounds in Omunkunzi root could have reduced them. Coliforms, yeasts and moulds counts were not significantly different (p<0.05). No pathogenic bacteria were found in either product. The lactic acid bacteria identified belonged to the genera Lactobacillus (Lb.) (Weissella), Leuconostoc (Leuc.), Lactococus (Lact.) and Streptococcus (Str.) Twenty representative strains of LAB isolates were identified to species level; three belonged to the species Lb. delbrueckii subsp. lactis and two belonged to Lb. plantarum and two to Weissella confusa (former Lb. confuses). Three belonged to Str. salivarius thermophilus, three to Leuc. lactis, and two to Leuc. mesenteroides subsp. mesenteroides. Three belonged to Lact. lactis subsp. lactis and two belonged to Lact. lactis subsp. cremoris. Significant differences (p < 0.05) in descriptive and consumer sensory attributes scores were observed between traditional and laboratory Omashikwa. Sensory attributes scores of TO on the levels of syneresis was 3.4 compared to 2.9 for LO, filth 3.0 compared to 1.8 in LO, rancidity scores were 3.4 in TO compared to 1.8 in LO, and bitterness 4.2 in TO compared to 2.5 in LO. Aroma scores were 2.6 for TO and 4.2 for LO, viscosity 2.5 (TO) and 3.8 (LO) and texture 2.7 for TO compared to 4.2 for LO. There was an 80% preference score given to the laboratory Omashikwa by the young consumer panelists. The results of this study indicate justification of using B. albitrunca root in the processing of Omashiwa by the rural community to improve the quality of Omashikwa in terms of flavour, smell and consistency compared to other traditional fermented milk products and in the absence of modern technology. However, application of good manufacturing practices on unit operations, particularly heat treatment of milk prior to fermentation, use of lactic acid starter cultures, maintenance of good hygiene and sanitation including packaging, seem to be the effective methods to improve and sustain the quality and safety of traditional fermented buttermilk (Omashikwa) for a wider market and better price. Namibia Dairies Ltd, just like any other dairies in the region and elsewhere, manufactures buttermilk, a byproduct of butter that is fermented with mesophilic lactic acid cultures and branded as Omashikwa for the purpose of marketing. It has nothing to do with traditional Omashikwa as such; B. albitrunca root is not added and is processed by using modern industrial method. In addition, additives such as preservatives (potassium sorbate), stabilizers (pectin) and sugar are added and packed for distribution. This research project therefore investigated the processing technology, physico-chemical, microbiological, viscosity and sensory quality of traditional Omashikwa. The remedial measures to curb inconsistency and poor quality experienced in Omashikwa processed in Namibia were also investigated and scientific measures were proposed for production of quality Omashikwa for marketing to a wider community. Since laboratory processing method of Omashikwa gave a better quality product compared to traditional method in terms of microbiological quality, sensory attributes, viscosity, filth content, syneresis and general appearance, laboratory processing technique of processing Omashikwa is therefore recommended as an alternative and appropriate processing method for small scale production in the rural set up to improve the quality of Omashikwa. / Thesis (PhD)--University of Pretoria, 2010. / Food Science / unrestricted

Traditional medicine has become an important part of healthcare worldwide. It is estimated that about 25 percent of prescribed medicines contain plant products or active compounds derived from plants. In South Africa, traditional medicine forms part of the culture and tradition of most communities. Garlic compounds have been shown to have a variety of antimicrobial properties. Amongst these are antifungal, antibacterial, antiviral and anti protozoal activities. Allicin and its breakdown products have been shown to be the main active compounds which possess these properties. Tulbaghia violacea has been used for the treatment of a variety of illnesses including asthma, fever, oesophageal cancer, constipation and hypertension. This study investigated the antifungal nature of T.violacea on the morphology, spore germination and lipid synthesis of Aspergillus flavus and Aspergillus parasiticus. The results of this study showed that the plant extract inhibited A. flavus growth at a minimal inhibitory concentration of 15mg/ml and was fungicidal at 20mg/ml and above. A. parasiticus was not inhibited at 25mg/ml indicating resistance to the inhibitory component of the plant extract. A measure of metabolic activity using the XTT assay showed reduced metabolic activity in the presence of increasing concentrations of the plant extract. Higher extract concentrations resulted in higher percentage inhibition of fungal growth for both fungal species with up to 98 percent inhibition being observed for the highest extract concentrations for both fungi. Germination was also delayed in the presence of 15mg/ml plant extract concentration by up to 60hr for A. flavus and 48hr for A. parasititcus. The TEM results showed increased thickening of the cell wall with higher extract concentrations. The thickening was greater for A. flavus than for A. parasiticus. Cell wall thickening may be the reason for the delay in germination in both species. Lipid production was reduced in the presence of plant extracts when compared to the control. The plant extracts inhibited triglyceride production at 15mg/ml for both A. flavus and A. parasiticus. The results therefore indicate that T. violacea extracts are antifungal and probably affect germination through interactions with the cell wall. It is possible that the extract affects lipid production in Aspergillus species.

Resistance of human pathogenic bacterial strains results in selective pressure against known antibiotic. However, plant derived compounds that possess antibacterial potential are currently being investigated for treatment of wound infections in diabetic patients as they are inexpensive and non-toxic. Hence, this dissertation was designed to evaluate two medicinal plants (Brachylaena elliptica and Brachylaena ilicifolia) traditionally used in the treatment of various diseases such as diabetes, and its secondary complications in diabetic patients. The in vitro antioxidant activity of both plants were evaluated using DPPH (1, 1-diphenylhydrazl), ferric reducing power, ABTS (2, 2’-azino-bis-3-ethylbenzothiazoline-6-sulfonic acid), NO (nitric oxide) and H2O2 (hydrogen peroxide) techniques. The antibacterial test and Minimum inhibitory concentration (MIC) was determined by agar dilution method against 5 bacteria strains (Pseudomonas aeruginosa, Staphylococcus aureus, Streptococcus pyogene, Proteus vulgaris and Proteus mirabilis) infecting wounds in diabetic patients using amoxicillin and ciprofloxacin as positive control. The phytochemical analyses were assessed using standard published methods. Identification of bioactive components in essential oils of both plants were assessed using GCMS. The aqueous and ethanol extracts of both plants were also evaluated to identify bioactive components using LC-MS. The results of the phytochemical analysis revealed the presence of phenols, tannins, flavanoids, flavanols, proanthocyanidins, saponins and alkaloids in both plants. Both plants indicated strong antioxidant activities which might be due to the presence of bioactive compounds. The aqueous and ethanol leaf extracts of both plants demonstrated appreciable broad spectrum activities against these wound pathogens with MIC ranging between 5 and 0.3 mg/ml. The GC-MS analysis of the essential oils of both plants revealed the presence of monoterpenes, oxygenated sesquiterpenes, phenolics and esters. The LC-MS analysis of the aqueous and ethanol leaf extracts of both plants showed that both plants are rich in alkaloids, terpenes, terpenoids, monoterpernoids, and flavanoids. Conclusively, this study has partially justified the ethnomedicinal use of B. elliptica and B.licifolia leaves for the treatment of various diseases, including diabetes and wound infections caused by bacteria in diabetic patients. These may be attributed to the presence of antioxidant compound such as phenols, flavanoids, saponins, tannins, alkaloids and other phytochemical compounds.

With the knowledge that risk has become an omnipresent concept used to understand various social problems, this study aims to fill a perceived gap in literature by investigating the way in which risk discourse is applied to understand different categories of crime, namely traditional crime and corporate crime. It is hypothesized that risk logic is heavily applied to the understanding of traditional crime, with minimal attribution to conversations surrounding corporate crime. The pervasiveness of risk as a technique or tactic of government renders the study of its application to different types of crime an important addition to the existing risk literature. Using the method of a comparative content analysis, the parallels and discrepancies between the ways in which risk is used to discuss traditional and corporate crime by Canadian federal criminal justice organizations are explored. The results indicate a lack of focus on risk logic with respect to corporate crime, but demonstrate that risk discourse is perhaps not altogether absent from corporate crime discussions.

Magister Philosophiae (Land and Agrarian Studies) - MPhil(LAS) / Insecure access and limited rights to land are major factors contributing to poverty among rural women (Ellis,2000; Havnevik et al,2007). Despite that, rural women’s livelihoods are directly linked to land; they generally lack secure access to productive land. In acknowledging the inequalities in terms of land ownership among Malawians, the government of Malawi introduced a land reform project known as the Community Based Rural Land Development Project (CBRLDP) (GoM, 2002a). This study aims at assessing the effects of group-based titling of the CBRLDP on creating secure access to land and livelihoods of women beneficiaries.Using qualitative research design, methods such as in-depth interviews, focus group discussions and questionnaire surveys were used as sources of primary data and project reports while CBRLDP programme planning documents and evaluation reports as sources of secondary data were consulted. While the data shows that secure access to land could create women’s sustainable livelihoods,the study found that access to land and the livelihoods generated by the CBRLDP are gendered, for instance,there are more male beneficiaries as compared to women. With regard to women’s land rights, this study shows that women are still struggling in claiming their rights to land. Furthermore, the study found that the roles of traditional leaders in securing access to land and protecting women’s land rights within the CBRLDP remain unclear. The study also reveals that access to land alone is not enough for the creation of women’s sustainable livelihoods.
