- Description: M.Tech. (Homoeopathy) , Abstract: The use of nutritional supplementation amongst athletes has been well documented over the past decade. These reports suggest an increase in dietary and ergogenic supplementation use by athletes over time. Researchers state that although the use of nutritional supplements, vitamins, and mineral supplements are increasing in popularity, the pattern of use of these supplements is not well known (Müller and Krawinkel, 2005). The aim of this study investigated the use of nutritional supplements amongst athletes participating in 1st team sports at the University of Johannesburg (UJ).The aim of the study was achieved with the following objectives: Analysing the use of nutritional supplements amongst 1st team athletes and whether the athletes were aware of the potential adverse effects of some of the supplements they used. Gathering data on the athlete’s knowledge on the supplements they use, and determining where athletes received their information about these supplements. The information gained is intended to provide valuable information on the knowledge and attitude athletes have towards supplementation use, the types of supplements being used by athletes, and were athletes receive their information on nutritional supplements. This research was a quantitative, descriptive statistical survey design study. The sample group consisted of 187 athletes from a variety of sporting disciplines at UJ. The researcher obtained permission from all relevant bodies at the university. All the participants were met at their specific training area or prearranged area after consulting with their coaching staff. Participation was voluntary and consent was given by the participants prior to completing the questionnaire. The questionnaire took about 5-10 minutes to complete. The data from the questionnaires was captured by the researcher and it was analysed with the assistance of STATKON, UJ, by using custom tables, .frequencies, and Chi-Square analysis. The results suggest that more than half of the participants make use of nutritional supplements to enhance their sporting performance. There is little gender difference...

- Description: M.Tech. (Engineering: Chemical) , South Africa has the second largest fluorspar reserves in the world, but about 95% of the mined fluorspar is exported without local beneficiation that would otherwise increase foreign exchange earnings., Creamer Mining Weekly G-Other Trade Topic- Investment, (2005). The first step of a possible local beneficiation process would be the feeding of fluorspar solid from a hopper fitted with a screw feeder, using nitrogen gas to transport the powder into a non-transfer plasma reactor system. This study had as a main goal the optimization of the applicable continuous feeding parameters. The objectives of the investigation were: (a) Evaluation of the feeding system. (b) Evaluation of pumping/vacuum generation requirements. (c) Evaluation of the effect of using solid powder with non - uniform particle size. (d) To develop a model to enable the design and preliminary costing of a fullscale plant. Tests were performed in a test rig constructed for this purpose using different pipe diameters and nitrogen flow rates for the transport of the powder. It was found that the level in the hopper would have to be kept constant or a control system would have to be implemented in order to maintain a constant powder feed rate. In addition, a model was developed for the transport of the powder, and was used to optimize the pipe diameter required. An initial estimate of the operating cost and earnings of a possible full scale plant indicated that the beneficiation process would be very profitable. It is therefore suggested that this process be investigated further for conditions closer to the optimum modelled in a mini-pilot plant operation that includes the plasma reactor system in preparation of full scale implementation

- Description: M.Tech. (Homoeopathy) , Psychological stress refers to an individual’s interaction with what he perceives as adverse or threatening phenomena of the external environment (stimulus) and the ensuing physiological response that occurs within the body. Although the stimulus itself may not be harmful, the physiological reaction of the individual to the perceived threat may lead to health consequences. University students may experience greater levels of stress than the average population. They may also experience symptoms of anxiety, irritability, sleep disturbances and impaired memory due to psychological stress. These symptoms may be exacerbated by concomitant use of alcohol and stimulants such as nicotine and caffeine, which students may use as coping mechanisms. Conventional treatment for stress might include anti-depressants and anxiolytics that often have adverse effects. TranQuin® Day Formula is a combination vitamin and herbal supplement formulated to assist the body to cope with stress. Although each individual vitamin and herbal constituent of TranQuin® Day Formula has been thoroughly researched, to date, no research has been conducted on the efficacy of TranQuin® Day Formula dietary supplement for the treatment of psychological stress in university students. The aim of this study was to determine the efficacy of TranQuin® Day Formula supplement on psychological stress in university students, with the use of the Cohen’s Perceived Stress Scale-10 (PSS-10) and Goldberg’s General Health Questionnaire-28 (GHQ-28). Thirty participants, both male and female, between the ages of 18 and 49 years, who obtained a minimum score of 10 on the Cohen’s Perceived Stress Scale-10, were selected to participate in this six week, double-blind, placebo-controlled study. Participants were also requested to complete Goldberg’s General Health Questionnaire-28. The scores obtained by the participants on both stress scales were measured at the beginning of the study (week 0) to obtain a baseline score, in the middle of the study (week 3) and at the end of the study (week 6). The participants were randomly divided into the control and experimental groups. Participants were asked to take two capsules of the supplement or placebo, preferably in the morning after breakfast, or the first meal of the day, for the duration of the study period (6 weeks). Each participant received a daily data sheet which recorded capsules taken and any symptoms experienced, as well as any other medication taken. The results of the study were statistically analysed using the Mann-Whitney-U Test, the Shapiro-Wilk Test, the Wilcoxon Signed Ranks Test, Friedman Test and descriptive statistics.
