Thesis (DTech (Public Management))--Cape Peninsula University of Technology, 2007 / Since 1992 the National Research Foundation and the Department of Trade and Industry, with support from industry, have been running a funding initiative under the auspices of Technology for Human Resources in Industry Programme (THRIP). This initiative provides funding to qualifying academics/researchers in South Africa's tertiary institutions and science councils to conduct research and development-oriented (or applied) research. This collaborative funding of applied research is geared to facilitating cross-transference of knowledge, skills and resources across academic institutions, government science, engineering, technology institutions and the industrial sector. It is also expected that research and project outputs will be commercialised to improve the competitiveness of South African industry in the face of globalisation and technological advancement. With public money spent on research projects of national importance, impact and value for money become Vitally important, hence the need for impact assessment. A non-probabilistic sample of 52 research projects in seven standard industrial classification categories or sectors conducted by 44 project leaders (who are academics/researchers) based in seven traditional universities, one former technikon (now university of technology) and three divisions of the Council for Scientific and Industrial Research, were assessed for impact. A non-experimental design was used, involving synergising the goal-attainment and side-effects evaluation models, and reinforcing them with two elements of causal tracing, temporal precedence and coherence, to facilitate attribution of benefits and impacts. THRIP's strategic objectives served as relevant indicators for impact assessment since projects' objectives co-terminate with them. In the context of the research, a definition of 'performance indicator' as "evidence of what has actually happened" was adopted, lending weight to project leaders' reports of projects' impacts. 'Success', defined in terms of projects' not only accomplishing their objectives, but also yielding value to beneficiaries and stakeholders, is posited as a possibly problematic term given that different stakeholders might have different criteria of judging it. Responses obtained from questionnaires administered to project leaders and industry partners' or sponsors' contact persons, the latter for triangulation, were analysed and categorised into four broad thematic areas: human resource development/intellectual, commercial/economic, social and technological. A number of findings emerged from the main questionnaire. A little more than half (56%) of the projects were completed and 44% were ongoing; majority (85%) were implemented according to plan; three categories of primary beneficiaries were cited by project leaders; projects were meant to address multiple problems/situations; they had multiple objectives; and majority (92%) were successful and made many impacts. Managerial strategies, supplemented by environmental and other factors, contributed to projects' success. Several reasons were offered for failure or inconclusiveness.

Submitted in partial fulfillment of the requirements for the Degree of Master of Technology: Biological Sciences, Technikon Natal, 2000. / This study focussed on the anti-bacterial, anti-fungal and anti-protozoal activity of four plant extracts, maackiain and formononetin from Virgilia oroboides and chlorophorin and lroko from Chlorophora excelsa / M

The major problem addressed by this study was to investigate the relationship between characteristics of the research methods used in selected subject subfields. In order to carry out the investigation a non-experimental design was employed, and an evaluative instrument was developed for assigning a quantitative score to published research based on characteristics of the research methods utilized. Evaluative scores were thus assigned to 244 randomly selected research studies drawn from two scientific subfields manifesting different rates of growth.

A number of biologically active chromones occur in plants (eg. Khellin) and research in this field has eventually led to the discovery of chromoglycic acid, which is widely used as a sodium salt in asthma therapy. Since biological activity may be related to acidity, a range of chromone-2-carboxylic acids have been prepared via Claisen acylation of substituted o- hydroxyacetophenones and their acid dissociation constants determined potentiometrically to explore substituent effects. From this study it has been found that introduction of certain groups does have a marked effect on acidity. A variety of acrylamide derivatives have been prepared via the dimethylamine-mediated ring opening of chromone-2-carboxamides which, in turn, were prepared from the chromone-2- carboxylic acids via the corresponding acid chlorides. Variable temperature NMR spectroscopy was employed to examine the effect of substituents on the rotational barriers and it has been found that for the acrylamides examined, ring substituents have little effect on the rotational barriers. A combination of low resolution, high resolution and meta-stable peak analysis has been used to study mass fragmentation patterns for a series of acrylamide derivatives. The proposed fragmentation pathways for selected peaks have been found to be common to all the spectra examined when differences in the atomic masses of substituents were taken into account.

Barium peroxide was selected as oxidant in a fundamental physico-chemical study of binary pyrotechnic systems on account of its apparently simple decomposition stoichiometry. With this selection, the choice of fuel was governed by the requirements of a self-sustaining reaction at combustion temperatures below the melting point of the platinum/rhodium thermocouples (∼1760°C) used for recording temperature-time profiles during burning, and at burning rates not exceeding the response of the sensors used to monitor combustion. Both manganese and molybdenum metal powders satisfied the above requirements. Strontium peroxide was also available as an oxidant and so the combustion of binary metal/oxidant systems using both fuels and both BaO₂ and SrO₂ oxidants was investigated. The Mn/BaO₂, MoBaO₂ and Mn/SrO₂ systems burnt over a wide range of compositions, but the range of ignitable compositions for the Mo/SrO₂ system was very limited. The linear burning rates, for all these systems, ranged from 2 to 12 mm s⁻¹ and burning rates were increased by the use of smaller particle-sizes of fuel and greater loading pressures. Inert additives generally decreased the burning rate. Temperature-time profiles were recorded for all the compositions which sustained combustion. Kinetic parameters were estimated from the shapes of these profiles using procedures developed by Hill et al and Boddington and Laye. Activation energies derived from the profiles were low (3 to 40 kJ mol⁻¹) and support suggestions that reactions at high temperatures are controlled by diffusion processes. Thermal analysis was used to identify the processes occurring in the four systems. The main exothermic events were observed to correspond approximately with the onset of oxidant decomposition. A pre-ignition reaction was tentatively identified in the Mn/BaO₂ system. Oxidation of the metal fuels was generally incomplete, probably because of the formation of protective layers of product. Activation energies, derived from thermal analysis results, were in the range of from 70 to 720 kJ mol⁻¹. Ternary systems containing either mixed fuels or mixed oxidants were also examined. No interactions hetween the fuels or between the oxidants were observed. Other techniques used included bomb calorimetry, measurement of thermal conductivity, X-ray powder diffraction, infrared spectroscopy and scanning electron microscopy.

The thesis takes the form of a collection of publications and patents concerning gold extraction which were presented over a period of 18 years while employed at the Anglo American Research Laboratories.

Research data management (RDM) focuses on the organization and description of data, from its entry to the research cycle through to the dissemination and archiving of valuable results. RDM entails storage, security, preservation, compliance, quality, sharing and jurisdiction. In the academic world, RDM can support the research process by searching for relevant data, storing data, describing data and advising researchers on good RDM practice. This study focused on developing RDM services. The aim of the study was to establish the role Makerere University Library could play in developing RDM Services. A number of questions were formulated to guide the researcher in finding answers to the research questions. A literature review, based on the research sub-questions, was carried out. The review covered the concept of RDM, academic libraries and their RDM practices, various RDM services in academic libraries, RDM services that require sustainability and how current researchers, in general, manage their data. The research undertaken took a qualitative approach with a case study design. This was due to the need to gather in-depth and comprehensive views and experiences regarding RDM at Makerere University. A purposive sampling technique was used to identify researchers who are actively involved in managing research data at Makerere University. Data were collected using semi structured interviews, from eight participants; one from each college. The participants were selected because of their knowledge about RDM and semi-structured interviews were preferred due to their flexibility. An interview schedule was used as the data collection instrument. Data was transcribed into Microsoft Word for easy analysis. Findings that addressed the research question and sub-questions were presented and interpreted in chapter four and conclusions as well as recommendations were discussed in detail in chapter five of this research report. In summary it is possible to say that although researchers, from across the entire university, generate big volumes of research data it appears that researchers themselves manage, control and store their data making use of different removable devices. This is risky. So there is a need to develop RDM skills for all stakeholders. It does appear though that the researchers at Makerere University would be willing the support of RDM services if these are developed by the library. / Mini Dissertation (MIT)--University of Pretoria, 2017. / Carnegie Corporation of New York / Information Science / MIT / Unrestricted
