- Description: Chapter One is an historical review of the rejection of colonial domination in various states in Africa, before the spotlight was directed at the relationships between the "white" and "black" inhabitants of South Africa. The numerous problems which arise out of this inter-relationship can best be ascribed to the identity crisis which "white" and "black" experience in a multi-lingual country. The South African society needs to normalise its relations with cultural and language groups by means of communication. Chapter Two reviews the historical background, linguistic characteristics, the use, functions and the distribution of the ten most important languages of which the South African community consists. The diversity of these languages generates and complicates the debate which currently prevails concerning a language policy for a future non-racial South Africa. The geographical, social, historical and cultural factors which are conducive and non-conducive to language distribution are high-lighted in Chapter Three. In a changing South Africa, where affirmative actions are being insisted on, it is expected that the current privileged position of Afrikaans will be placed under political pressure. A painful process of self-examination by Afrikaans-speaking Afrikaners - one of the major role-players in the current controversy concerning the continued existence and status of Afrikaans in a "postApartheid era" - has been precipitated. Chapter Four looks at how the "white", "coloured", "black" and "Indian" Afrikaans-speaking Afrikaners' mother tongue has evolved to its present status. The arguments for and against, viewpoints of, and pleas for the re-unification of Afrikaans-speaking Afrikaners to a larger single power base is emphasized. The possible future status and functions of Afrikaans insofar as its present status, functions and attitudes are concerned, are extrapolated in Chapter Five. The viewpoint concerning a possible scenario for the above-mentioned matters as expressed by a wide spectrum of South African society - academics, cultural groupings, political leaders, non-mother-tongue speakers of Afrikaans - is evaluated. A scenario of the possible role of Afrikaans in a "post-Apartheid era" in South Africa is sketched in Chapter 6. The conclusion is that the Western culture as understood by the black man, differs in more than one way from the perception of the white man. First and foremost, the acceptance of and respect for the languages and cultures of all fellow South Africans is the first step towards seeing all South Africans as being Africans. , Opsomming: Hoofstuk Een is 'n historiese oorsig van hoe die verwerping van koloniale oorheersing elders in Afrika diekontaken verhouding tussen die "wit" en "swart" inwoners van Suid-Afrika onder die soeklig geplaas het. Die talle probleme wat uit die kontaksituasie spruit, kan gereduseer word tot die identiteitskrisis wat "wit" en "swart" in 'n multitalige land beleef. Die Suid-Afrikaanse gemeenskap het In dringende behoefte aan die normalisering van die verhoudings, vera! deur middel van kommunikasie, tussen die kulturele- en taleverskeidenheid. In Hoofstuk Twee word daar gekyk na die historiese agtergrond, linguistiese eienskappe, gebruik en funksies en die verspreiding van die tien vemaamste tale waaruit die Suid-Afrikaanse talegemeenskap bestaan. Die diversiteit van tale genereer en kompliseer die debat wat tans oor 'n taalbeleid vir 'n toekomstige nierassige Suid-Afrika gevoer word. Die geografiese, sosiale, historiese en kulturele faktore wat taalverspreiding bevorderof teenwerk, word in Hoofstuk Drie belig. In 'n veranderende Suid-Afrika, waar op regstellende aksies aangedring word, kan daar verwag word dat Afrikaans as gevolg van sy bevoorregte posisie onder politieke druk geplaas sal word. Vir die Afrikaanssprekende Afrikaners, as een van die hoofrolspelers in die polemiek oor die voortbestaan en status van Afrikaans in 'n "post-Apartheidsera", het dit 'n pynlike proses van selfondersoek gebring. In Hoofstuk Vier word daar gekyk hoe die "blanke", "anderskleurige", "swart" en "Asiatiese" Afrikaanssprekende Afrikaner sy moedertaal tot op hede ervaar het. Die argumente vir en teen, sienings van, en pleidooie vir 'n hereniging van Afrikaanssprekende Afrikaners tot 'n groter mags basis word belig.

Daar word tot die gevolgtrekking geraak. dat die Westerse kultuur, soos verinnerlik deur die swart man, in belangrike opsigte van die van die wit man verskil.

- Description: The study investigated risk and adoption of mobile financial services among some users in selected municipalities within the Eastern Cape Province, using the theory of reason action, technology acceptance model and the theory of expected utility and risk aversion to explain the variables. Moreover, the explanatory research design and quantitative data collection approach formed the methodology adopted in the study. In addition, a validated semistructured interview questionnaire was used as a research instrument in the study. The multistage, stratify, purposive and convenience sampling techniques were applied to select 6 research sites and 386 research participants for the study. Three research objectives were stated and tested using descriptive, Principal Component Analysis (PCA) to profile the risk and logit regression statistics. The results of statistical analysis show different level of cross tabulation between MFS and education level, all the 6 different locations, individual age range, job type, and average income of individual. Analysis revealed that age and income level of individuals have the highest relationship with the use of MFS. The statistical analysis used was the logistic regression. Pool of effort of all the stake holders in financial services sector should focus on including the low income earners and the technology should be simple enough for the use of the older generation.

An analysis of the suitability of prescribed geography textbooks for Ciskei pupils in standard 6

- Description: Research has shown that in the South African school context textbooks are perceived as the most important guide to subject content. It is essential, therefore, that pupils and teachers should possess skills and strategies that they can use to interpret and understand the textbook. Equally, textbook writers ought to be aware of the cues pupils need to facilitate the learning process. Problems that hinder the learning of geography subject content from textbooks may arise from, among other things, the style in which the text is written, the way in which concepts are developed, the presentation of visual materials and elements of bias and stereotyping. This study scrutinises and analyses two standard 6 geography textbooks prescribed for Ciskei schools to assess the extent to which these textbooks consider the language competence of the pupils, explain and develop concepts, and in general promote the geographical education. Interviews with Ciskei teachers revealed that Standard 6 pupils encounter difficulties in the geography textbooks which are attributed to the fact that they are second language learners and they lack the requisite skills for interpreting visual materials. The analysis of the textbooks revealed that despite efforts made in recent years to rectify the most blatant aspects of bias and stereotyping and to improve the presentation of textbooks, a number of serious problems continue to exist particularly with regard to the Standard 6 learner of geography. The study attempts to alert writers of texbooks and teachers to factors which need to be taken into consideration to assist second language speakers toward effective learning.

An investigation into how Zimbabwe's Bulawayo viewers negotiate the gay storyline in Generations

- Description: This study seeks to evaluate how aspects of religion, culture, political context, education and class, amongst others, impact on the manner with which Zimbabwe’s Bulawayo residents make sense of media messages which explore issues of homosexuality, as encountered in the soap opera Generations. This is against the backdrop of Zimbabwean legislation, such as the Sexual Deviancy Act, which criminalises homosexuality and the state victimisation of gays and lesbians in this country. The inclusion of homosexual liberties was rejected by all political parties and both public and private media in the recent drafting of a new rule of law. The legislation, including gay rights exclusion in the new constitution, and state action has perpetuated an impression that Zimbabwe is a deeply homophobic society. As a starting point the study examines the claims of the media imperialism thesis which supposes an all-consuming power of western media and next examines Straubhaar’s thesis of ‘cultural proximity’ which argues that there is often a preference for regional media, which is proximate to viewers’ local culture, language and identity. The study explores the prominence of South Africa as a regional media player and that proximate identities with some cultures in that country have played a role in drawing some Bulawayo viewers to South African television, as they feel slighted by Zimbabwean media. Utilising qualitative research methods, the study explores whether or not the representation of gay images on this South African soap opera provides viewers with opportunities for ‘symbolic distancing’. The concept highlights that when people have insight into lifestyles that are different from their own, they use that as a resource to critically analyse their own lives and cultural understandings. The study evaluates if Bulawayo viewers’ sentiments towards homosexuality has been challenged and changed through their interface with the soap opera, Generations.

- Description: The study set out to investigate the perceived effects of the Leadership Development Programme, a two-years training programme for school principals in the Ondangwa East Educational Region of Namibia. The objective has been to find out whether the training curriculum and content were related to what participating principals thought they needed to help them to do their work better, and improve their schools. Data were collected through interviews with two of the first group of nine principals who have completed the training. The study has found that the Leadership Development Programme helped the participating principals to experience personal changes and professional growth. Through the process of participatory action research, the Leadership Development Programme has been able to bring together theory and practice. It has also helped the principals to recognize their responsibility for planning, implementing and evaluation of action, and problem solving initiatives in their schools. The study has also found that the Leadership Development Programme recognized, and therefore applied, the element of experiential/adult learning. Although the Programme has had its basic core curriculum, its content and training process have been flexible in the sense that the Programme tried first to establish what participants knew, and then assisted them to gain a new and enquiring perspective on their knowledge and practice, which helped them to become reflective practitioners. While the study could not establish with a degree of certainty as to what extent the principals have taken up the processes of the training Programme in their schools, it has, however, found that there are many positive changes brought in about schools during the time the training was running. Secondly, while the study could obviously not establish a direct link between every change and the inputs made by the training Programme, it concluded, however, that the Programme at least brought about changes in the mindsets of principals, which were conducive to teaching and learning. What was important, though, was the question of how many of the initiatives were still bearing fruit three years after the training has taken place.

- Description: This study investigates whether a leadership and management development programme changed the management perceptions of the teachers of one of the schools that participated in the programme. The programme seeks to change the organisational culture of schools and develop effective management. The development philosophy of the programme is informed by literature on school effectiveness, organisation development, whole school development and systemic change. My research is conducted in the interpretive paradigm. Interpretive researchers view reality a construct of the human mind, and therefore the way people perceive the world is not necessarily the same since there can be different understandings of what is real. I employ convenience sampling to select the school and purposive sampling to identify my research participants. Whilst overall impression that the data conveys is that much of the programme does not seem to have had a lasting effect on the culture of the school, it nonetheless made an impression on the teachers’ perceptions of management. There clearly seems to be a greater appreciation of participative management processes. The reintroduction of proper prior planning played a decisive role in re-establishing sound work ethics at the school and contributes to a more structured approach to events at the school. Some sort of organisational learning has also been introduced at the school. The realisation on the part of the staff that they now have their destiny in their own hands is an especially critical development. And whilst the vision is not a compelling force in the organisation, it has nevertheless produced some strategic focus at the school. The insights and skills they acquired concerning resource management will also stand them in good stead.

Whilst overall impression that the data conveys is that much of the programme does not seem to have had a lasting effect on the culture of the school, it nonetheless made an impression on the teachers’ perceptions of management. There clearly seems to be a greater appreciation of participative management processes. The reintroduction of proper prior planning played a decisive role in re-establishing sound work ethics at the school and contributes to a more structured approach to events at the school. Some sort of organisational learning has also been introduced at the school. The realisation on the part of the staff that they now have their destiny in their own hands is an especially critical development. And whilst the vision is not a compelling force in the organisation, it has nevertheless produced some strategic focus at the school. The insights and skills they acquired concerning resource management will also stand them in good stead.

- Description: The researcher attempted to investigate attitudes of community stakeholders towards stigmatization of people living with HIV/AIDS (PLWHA). This is because people living with HIV/AIDS are usually subjected to negative and positive attitudes in South African communities. The study made use of a case study as a specific research design which was explorative and descriptive. The study employed in-depth interviews, focus group discussions and secondary data sources to collect data. The study was a cross-sectional and adopted a non-probability sampling methodology, but specifically purposive technique. The study used 25 participants who consisted of 12 PLWHA, 5 nurses, and 8 selected community members. The data were analyzed through content thematic analysis. The findings that emanated from the study were: awareness of stigmatizing attitudes subjected to people living with HIV/AIDS (PLWHA); the attitudes displayed towards PLWHA, the drivers of stigma; the impact of stigma on PLWHA; PLWHA suffers immense psychosocial deficit; PLWHA face a state of abject poverty; PLWHA faces Psycho-emotional deficit; the secrecy surrounding the virus forms a fertile ground for infection; fear of contagion; stigma confounds chances of HIV/AIDS disclosure and issues of confidentiality. The study recommended that: the government should prioritize the PLWHA’s human rights; adoption of social media platforms to raise awareness and education of HIV/AIDS; collaboration between the Department of Health and the Department of Traditional affairs; invention of a youth-based psycho-emotional programme; and establishment of in-depth community supported interventions.

- Description: The primary objective of the study is to examine the livelihood impact of biofuel production on small-scale rural farmers participating in the MMI project in the local districts in Limpopo province. The study is theoretically underpinned by the sustainable livelihoods framework which provides a nuanced analysis of the complex nature of poverty and livelihoods. The framework was used to examine how MMI as a structure with its own processes (incubator model) plays a role in creating a means for farmers to have more access to livelihood assets which would help them achieve improved livelihoods outcome. The findings of this study reflect what has already been articulated in literature about small-scale biofuel projects. This study shows that MMI’s incubator plays an important role for 73% of the farmers to access all of the livelihood assets and ultimately improving their farm income and food security. Furthermore, 90% of the participants admitted to have received support from MMI in a number of ways. This includes the provision of farming inputs, labour and access to markets in addition to training, mentoring and coaching. The study also found that despite the overwhelming support, both MMI and farmers face a number of challenges. Farmers still lack adequate farming inputs, transport, access to markets and vulnerability to natural disasters. MMI faces challenges in raising funds to provide inputs to all their incubatees and lack of adequate mechanization. Lack of transportation affects both farmers and MMI in that farmers find it difficult to access MMI service. In the same light, MMI has found it difficult to reach farmers for post-incubation, coaching and mentoring or delivering inputs; this can be challenging and a costly process. MMI’s biofuel production project has the capability for improving rural livelihoods through agriculture. The study concludes by recommending that MMI should improve its own capacity in order for them to better the lives of the farmers they assist. This study is significant for contributing to a field which has received less academic and research attention in South Africa. Its scholarly contribution will enhance the existing body of knowledge on biofuels and rural development in South Africa

- Description: This work presents the syntheses, photophysical and photochemical characterization of zinc tetracarboxyphenoxy phthalocyanine (ZnTCPPc, 3) and its gadolinium oxide nanoparticle conjugate (4). By means of spectroscopic and microscopic characterization, the conjugation of the ZnTCPPc to the silica coated gadolinium oxide nanoparticles (Si-Gd2O3 NPs, 2) through an amide bond was confirmed. The thermal stability, morphology, nanoparticle sizes and their conjugates with the Pc were studied using ThermoGravimetric Analysis (TGA), Fourier Transform Infrared spectroscopy (FTIR), Transmission Electron Microscopy (TEM) and powder X-ray diffractometry (XRD). Conjugation of ZnTCPPc to the magnetic nanoparticles, proved to have a negligible effect on the photophysical parameters of the phthalocyanine, where a slight decrease in fluorescence and triplet quantum yields and lifetimes was observed. The singlet oxygen quantum yield, however, increased slightly upon conjugation, suggesting that the overall efficiency of the ZnTCPPc as a photosensitizer had improved. Physical mixing of the ZnTCPPc and the silica-coated gadolinium nanoparticles also showed an improvement in the singlet oxygen quantum yield and triplet lifetime, also showing an enhanced efficiency for the photosensitizer and therefore photocatalysis. ZnTCPPc (3) alone and the Pc-gadolinium oxide nanoparticle conjugate (4) were therefore electrospun into nanofibers to create a solid support. The fibers were characterized and their diameter sizes and composition was studied confirming the incorporation of the phthalocyanine and gadolinium oxide nanoparticle. Increased singlet oxygen generation resulted in increased Photodegradation of the environmental pollutant Orange G and the fibers were found to be more efficient as photocatalysts compared to the photosensitizer in solution. The nanomaterial may therefore be applied to the photodegradation of Orange G.

Corporate Social Responsibility as a strategy for community development in the Eastern Cape Province: The Case of Volkswagen in Uitenhage

- Description: The turn of the new millennium has brought with it a heightened emphasis on Corporate Social Responsibility (CSR), particularly more recently in the global South where underdevelopment is more prevalent. While corporates continue to be viewed as more better-placed than global South governments in the attempt to deal with underdevelopment, this contribution of corporates does not come naturally since their primary focus is making profit. In the case of South Africa, the CSR agenda is regulated primarily by two legal instruments: the B-BBEE Act and the Companies Act. This study set out to determine whether CSR is an effective strategy for community development (CD). The study relied on a qualitative research methodology, employing face-to-face interviews and focus group discussions as the primary sources of data. Data was gathered primarily from two sets of samples: a community sample which comprised of members from wards 47, 50 and 51 in Uitenhage; and a sample comprising of officials from the B-BBEE Commission, the Nelson Mandela Bay Municipality Local Economic Development, and the Volkswagen Community Trust. Participants were purposively sampled in order to save time and resources. The study established that although CSR can be employed for the purposes of achieving community development, there is need for dedicated policies that deal specifically with CSR and set the parameters within which CSR can be carried out. The effectiveness of the CSR agenda in South Africa, thus, relies heavily on the institution of an effective regulatory framework.

This discussion will situate identified discourses in relation to the subjects and objects to which it refers in an attempt to identify and interrogate dominant discourses which circulate to oppress and discriminate against female 'others' within the mental health setting. This discussion will serve to challenge mainstream, traditional psychology by questioning the utility of deploying these concepts within a South African context as well as the effects this deployment may have. A discourse analytic methodology is employed to identify the constructions of BPO by five mental health professionals working within a government setting. The analysis aims at interrogating the broader role of the identified discourses in supporting institutions, preserving power relations and transmitting ideological practices. Ultimately the aim of the research is to open up for critical debate, through the example of psychology and psychiatry's treatment of BPO; constituted as 'other', the possibility that there may be deleterious consequences for the wholesale acceptance of traditional psychological understandings by mental health professionals working within a South African context. , KMBT_363 , Adobe Acrobat 9.54 Paper Capture Plug-in

- Description: Zimbabwe, similar to other developing countries experiences a high level of informal employment. However, most informal jobs are situated in very poor working conditions and are characterised by decent work deficits. Despite the fact that various studies have shown the importance of the informal economy in that it provides livelihood earning opportunities for the majority of people in the Global South, it has remained a largely forgotten sector in policy making in most countries. It is, therefore, important that informal work be taken seriously and efforts must be made to improve working conditions for the urban working poor in the developing world. The purpose of this study is to investigate on the self-reported experiences of informal workers to understand their perspectives surrounding the concept of decent work in the Zimbabwean context. The case study is the Bulawayo metropolitan province, and this study targeted informal workers who trade within the central business district. The study also aimed to measure the decent work deficit scores between two economic sectors (food and clothing traders). This was done by testing the suitability of the Edward Webster Decent Work Deficit Index as a methodology of measuring decent work at a micro level. The analysis is based on a mixed methods study which was carried out through the use of a semi-structured survey. The study revealed that decent work for the sampled informal workers meant work related improvements, insurances and risk management, right of expression and business advancement skills which closely resembles the International Labour Organisation's conceptualisation of decent work. The study also highlighted that childcare assistance and disability insurance are concepts which remained excluded in the current conceptualisation of decent work. The thesis offers a new policy angle which shows that to promote decent work the concept of heterogeneity must be adopted because inequalities persist within the informal economy. The study also suggested that the Edward Webster Decent Work Deficit Index can be used as an appropriate methodology of monitoring the progress towards achieving decent work at the micro level i.e. industry or individual level. This is because since the formation of the decent work concept; the International Labour Organisation has only provided a methodology of how to measure the progress of decent work at the county level. The survey findings revealed that food vendors scored more poorly on the decent work deficit index compared to the clothing traders. The study also identified that food vendors and clothing traders are faced with different challenges which suggests that policy makers must take that into consideration when attempting to design policies or programmes which are aimed at assisting informal workers.

- Description: It was the objective of this project to provide a glass cleaner formulation for a wet wipe application with cleaning and anti-fogging properties. This glass cleaner formulation was developed for automotive glass i.e. interior of windscreens. This formulation relates to a glass cleaner with a composition comprising of: (a) a blend of amphoteric surfactants; (b) a solvent system with a combination of glycol ethers; and (c) an aqueous solvent system. This glass formulation must provide good cleaning properties while also providing good wetting and sheeting properties to assist with anti-fogging properties. The objectives were obtained using 2 specific approaches: The first was by using a blend of 2 amphoteric surfactants in an alkaline medium, allowing the glass surface to become more hydrophilic which will also assist with reduction of surface tension on the glass surface. The second was by using the glycol ethers that have good coupling properties and surface tension reducing properties. The formulation was evaluated using commercial standard test methods as per the industry. A predictive model was successfully obtained for each of the five criteria that were evaluated using the 25 formulations derived from the statistical design. There were variables and variable interactions that were antagonistic for some of the criteria which were found to be synergistic for others. To achieve satisfactory cleaning, the fogging rating had to be compromised.

- Description: This thesis presents a theoretical analysis of developments in the South African monetary banking sector and money market. In the first section, evolution of the political, social and economic environments over the past few decades are discussed to provide the reader with an idea of some factors responsible for the underdeveloped nature of this market. It has been argued that the domestic political and economic landscape is relatively stable. Nevertheless, factors such as Zimbabwe’s political and ensuing economic turmoil, coupled with numerous financial crises in other developing nations have had negative consequences on domestic financial market development and economic growth. The current state of monetary policy is also analysed, within the economic environment, and various policy considerations have been put forth concerning the inflation targeting policy. The thesis then goes on to scrutinise the statutory and institutional environments within which the monetary banking institutions operate. Recent changes in the regulations governing the operations of these institutions are identified, together with the consequences of such laws on banking institutions and possible amendments have been suggested. In particular, a system of Asset Based Reserve Requirements (ABRR) has been recommended, in place of the current cash reserve requirement, to ensure regulators create a level playing field in the financial sector. The system can also provide authorities with the necessary control required to direct funds to the most desirable sectors of the economy. Development of the interbank market and the effect of reduced banking competition on the efficacy of the South African Reserve Bank’s refinancing operations and inflation targeting policy are also considered. Finally, the thesis analyses some effects of financial development on the South African economy, and whether it is in the best interests of the country to pursue financial reforms with such vigour. While financial development may bring South Africa closer to international standards of best practice, the timing and extent of the reforms will be critical to guarantee success.

- Description: The main magnetite seam of the Upper Zone of the Rustenburg Layered Suite (SACS, 1980) on the Bushveld Complex is known to host the world‘s largest vanadium bearing titaniferous iron ores. The vanadiferous titanomagnetites, contain vanadium in sufficient concentrations (1.2 - 2.2 per cent V₂O₅) to be considered as resources and vanadium has been mined historically by a number of companies among them Anglo-American, Highveld Steel and Vanadium and VanMag Resources as well as currently by Evraz Highveld Steel and Vanadium Limited of South Africa. The titanomagnetites contain iron ore in the form of magnetite and titanium with concentrations averaging 50-75 per cent FeO and 12-21 per cent TiO₂. The titaniferous iron ores have been historically dismissed as a source of iron and titanium, due to the known difficulties of using iron ore with high titania content in blast furnaces. The economic potential for the extractability of the titaniferous magnetites lies in the capacity of the ores to be separated into iron rich and titanium rich concentrates usually through, crushing, grinding and magnetic separation. The separatability of iron oxides and titanium oxides, is dependent on the nature in which the titanium oxide occurs, with granular ilmenite being the most favourable since it can be separated from magnetite via magnetic separation. Titanium that occurs as finely exsolved lamellae or as iron-titanium oxides with low titania content such as ulvospinel render the potential recoverability of titanium poor. The Upper Zone vanadiferous titanomagnetites contain titanium in various forms varying from discrete granular ilmenite to finely exsolved lamellae as well as occurring as part of the minerals ulvospinel (Fe₂TiO₄) and titanomagnetite (a solid solution series between ulvospinel and magnetite) . Discrete ilmenite constitutes between 3-5 per cent by volume of the massive titanomagnetite ores, and between 5-10 per cent by volume of the magnetite-plagioclase cumulates with more than 50 per cent opaque oxide minerals. The purpose of this research was to investigate the mineralogical setting and distribution of the iron and titanium oxides within the magnetitite layers from top to bottom as well as spatially along a strike length of 2 000m to determine the potential for the titanium to be extracted from the titanomagnetite ores. The titanomagnetites of the Upper Zone of the Bushveld Complex with particular reference to the Northern Limb where this research was conducted contains titanium oxides as discrete ilmenite grains but in low concentrations whose potential for separate economic extraction will be challenging. The highest concentration of titanium in the magnetite ores is not contained in the granular ilmenite, but rather in ulvospinel and titanomagnetite as illustrated by the marked higher concentration of TiO₂ in the massive ores which contain less granular ilmenite in comparison to the disseminated ores which contain 3 to 8 percentage points higher granular ilmenite than the massive ores. On the scale of the main magnetite seam, the TiO₂ content increases with increasing stratigraphic height from being completely absent in the footwall anorthosite. The V₂2O₅ content also increases with stratigraphic height except for in one of the 3 boreholes where it drops with increasing height. The decrease or increase patterns are repeated in every seam. The titanomagnetites of the main magnetite seam display a variety of textures from coarse granular magnetite and ilmenite, to trellis ilmenite lamellae, intergranular ilmenite and magnesian spinels and fine exsolution lamellae of ulvospinel and ferro-magnesian spinels parallel to the magnetite cleavage. The bottom contact of the main magnetite seam is very sharp and there is no titanium or vanadium in the footwall barely 10cm below the contact. Chromium is present in the bottom of the 4 layers that constitute the main magnetite seam and it upwards decreases rapidly. In boreholes P21 and P55, there are slight reversals in the TiO₂ and V₂O₅ content towards the top of the magnetite seams.

- Description: The aim of the study was to determine the fatty acid composition, colour stability and lipid oxidation of fresh mince produced from fallow deer and to evaluate the effect of frozen storage duration on the retail display shelf life of the mince. A total of 31 fallow deer carcasses were used in the study. After cooling for 24hrs, the carcasses were deboned, external fat from the fore and hindquarter muscles removed and individually vacuum packed. For the first trial, seven fallow deer carcasses were used. Meat from the hind and fore-quarters of each carcass was divided into two equal batches per animal. One batch was minced (through a 5 mm die) and packed into oxygen permeable overwraps and refrigerated at 4°C for a period of eight days under retail display conditions. The second batch was vacuum packed and frozen at -20°C for 2 months at the end of which mince was also produced and monitored over an eight-day period under the same conditions that were used for the fresh mince. Colour, pH, lipid and myoglobin stability was determined. Proximate and fatty acid composition was also determined. No differences (P>0.05) were noted between proximate composition of fresh and frozen/thawed minced meat. The lipid content of fallow deer was 2.4 percent (±0.04). Total n3 fatty acids differed (P<0.05) between treatments and decreased with increased storage and display day. There were significant (P<0.05) treatment and time interactions on all measured colour parameters, TBARS and myoglobin forms. Fresh mince was lighter and had higher redness (a*) and yellowness (b*) values than mince from two months frozen stored meat. Hue angle for fresh mince remained stable throughout display whereas it increased for frozen/thawed mince. Fresh mince had lower TBARS values than frozen/thawed mince. Minced meat produced from frozen/thawed deer meat had higher surface met-myoglobin and total met-myoglobin percentages. Surface and total oxy-myoglobin percentage was higher in fresh mince. The first trial clearly showed colour and lipid stability differences between fresh mince and mince from frozen/thawed meat. It also showed that fresh mince has a longer retail display life than mince produced from frozen/thawed meat (six days and four days, respectively). In the second trial, the effects of frozen storage duration on colour and lipid stability were investigated. Twenty-four fallow deer were used. Twelve were harvested in June (6male 6female) and the other twelve in August (6 male 6female) of the same year.Twenty four hours after harvesting, the fore and hindquarter muscles of the carcasses were deboned, vacuum packed and kept at -20°C until October (i.e. 2months and 4months frozen storage period). Upon thawing, the meat was processed into mince following the same procedure used for the first trialand displayed for a fiveday period under retail display conditions. Frozen duration and gender had no effect (P>0.05) on the proximate composition of fallow deer meat. The total amount of saturated fatty acids (SFA) increased and total amount of poly unsaturated fatty acids (PUFA) decreased as frozen duration and display day increased (P<0.05). Frozen duration affected (P<0.01) lipid oxidation and percentage oxy-myoglobin. Mince pH and all colour parameters (L*, a*, b*,hue and chroma) differed (P<0.05) between treatments on day zero and three. Display day was a significant factor (P<0.05) on all measured parameters. By day three all parameters except pH showed signs of extended oxidation and discolouration as evidenced by reduced redness, decreased colour intensity and high TBARS values. This study showed that prolonged frozen storage negatively affects the colour and lipid stability of meat and increases oxidation of PUFAs during frozen storage. However, the study also suggests that although frozen/thawed meat has a shorter retail display shelf life; the proximate composition of the meat remains unchanged.
