- Description: Industry 4.0 is impressively creating a lasting impact on the manufacturing industry and on the industry outlook on the benefits of the implementation of new technology. The concept currently trending entails merging cyber systems, the Internet of Things, and the Internet of Systems all together to construct the revolutionary ‘Smart Factories’. The use of advanced technologies brings about new methodologies to improve the results of manufacturing. Complex activities will be performed by machines equipped in using intelligent information systems and new technology to improve productivity, enhance quality, and reduce costs of manufacturing products. South Africa is at the height of the ‘Fourth Industrial Revolution’ (4IR) which will essentially change the way we work. This innovative rubric of high-tech modernisation is characterised by a merging of technologies from the physical, digital, biological, and neuro-technological spheres. The hesitation over jobs being substituted with co-bots, a robot envisioned to actually cooperate with humans in a communal workplace, is profound. Skills volatility is estimated to affect all industries. There are uncertainties that the underprivileged and non-skilled would be thrust into an even profounder deficiency with the upsurge of the digital age. Organisations regard robotics and modern technology as strategic corporate tools that are utilised to enhance short- and long-term profitability and achieve operating goals. In dissimilarity, the application of robotics and modern technology in the place of work increases labour stability concerns, anxiety of downsizings and terminations within the workforce. The purpose of this research was to heighten the comprehension of smart factories in the manufacturing industry by conclusively embracing a methodical examination of the factors which influence the outlook of those involved concerning smart factory implementation and also of assessing the readiness of the South African manufacturing industry for 4IR towards 2030. The ‘golden thread’ running through the study is the significance of the impact of the 4IR on the workforce and the creation of new jobs for the future, the reskilling of the workforce and the enhancement of capabilities of future factories in embracing the implementation and the incorporation of advanced manufacturing principles in production processes. This must form a substantial consideration in the preparation of the vision of the “Incorporation of smart production in future factories within the fourth industrial revolution towards 2030”. The results of the in-depth analysis of future studies practice and theory in this research study give credibility to the argument that the way in which planning for the future of the 4IR in the South African context is taking place requires insightful adaptation by all stakeholders. The development of new insights through the application of futures studies is vital to this planning process, as is progressively demonstrated in the propensity for present-day business to enable collaborative decisions and strategies that are established on, and informed by, futures studies. This research has attempted to gain insight into the possible future of the implementation of 4IR elements within the future manufacturing factories in South Africa through the creation of four scenarios towards 2030. These are defined as follows: The Fifth Element, which is the ‘best case’ scenario, and to which the country aspires; the ‘worst case’ scenario, in which everything goes badly; the outlier future founded on a surprising, disruptive, emerging matter; and ‘business as usual’ in which no change takes place. The research additionally made efforts to determine the preferred future for the 4IR from a South African perspective, as a base for the Future Vision of the 4IR in the South African manufacturing industry towards 2030. Throughout this study, Inayatullah’s (2008) pillars of futures studies were implemented as a guide in mapping the present and future, further deepening and widening the future through the development of scenarios and, lastly, by transforming the future by narrowing it down to the preferred future. The South African manufacturing sector must select which path to follow in the decisions surrounding the acceptance of the 4IR as the country progresses towards aligning itself with the global players in technology acceptance. Through a unique and innovative approach, the establishment of an atmosphere of trust and the sharing of purpose, values and benefits, a collective Future Vision of the implementing of 4IR elements such as smart production in future factories within South Africa towards 2030, is achievable. All stakeholders must be committed to operating in collaborative partnerships, with government, society, local communities and the workforce all treading boldly together into a sphere of technological, commercial, environmental and social innovation.

Molecularly imprinted polymeric materials for adsorptive removal of nitrogen compounds from fuel oils

- Description: The deleterious effects of refractory polyaromatic hydrocarbons found in fuels such as organonitrogen compounds (quinoline, carbazole and its alkylated derivatives) are such that they emit NOx to the environment when combusted, thereby reducing air quality. These compounds also deactivate the catalyst used during fuel refinement and in catalytic converters of cars. Hydro-denitrogenation (HDN), a process currently being employed in petroleum refineries to eliminate organonitrogen compounds in fuels, is limited in treating these refractory compounds. Hence, this thesis describes the use of two separate complimentary approaches for the removal of organonitrogen compounds in fuel such as oxidative denitrogenation and adsorptive denitrogenation. The catalyzed oxidation of fuel oil model nitrogen containing compound, quinoline to quinoline N-oxide, was conducted under batch and continuous flow microreactor at 70°C by using tert-butylhydroperoxide (t-BuOOH) as oxidant and silica supported V2O5 as catalyst, followed by the selective adsorption of the quinoline N-oxide. An overall conversion of 62% quinoline N-oxide was observed. Quinoline-N-oxide in model fuel was absorbed by employing synthesized molecularly imprinted 2,6-pyridine-polybenzimidazole (2,6-PyPBI) nanofibers, 86% of quinoline-N-oxide was removed to give an adsorption capacity (qe) of 4.8 mg/g. DFT calculations to study the interactions of quinoline-N-oxide vs 2,6-PyPBI indicated that: (i) hydrogen bonding (through amino group of 2,6-PyPBI and oxygen atoms of the quinoline-N-oxide), (ii) pi-pi stacking and (iii) extensive number of van der Waals interactions took place. Several oxygenates from N-compounds were produced, thus, complicating the fuel matrix. Therefore, there is a need to move towards adsorptive denitrogenation. Poly-2-(1H-imidazol-2-yl)-4-phenol (PIMH) imprinted microspheres was prepared by suspension polymerization using 2-(2’-hydroxy-4-ethenylphenyl) imidazole as a functional monomer and ethylene glycol dimethacrylate as a crosslinker in the presence of various organonitrogen compounds (templates) to produce 2-(2’-hydroxy-4-ethenylphenyl) imidazole (PIMH). Imprinted microspheres show selectivity for various target model nitrogen-containing compounds with adsorption capacities of 6.8 ± 0.2 mg/g, 6.3 ± 0.3 mg/g and 5.8 ± 0.3 mg/g for quinoline, pyrimidine and carbazole, respectively. Adsorption selectivity increased in the order of quinoline (αi-r = 136.9) ˃ pyrimidine (αi-r = 126.2) ˃carbazole (αi-r = 86.3), when naphthalene was selected as a reference compound. Though, imprinted microspheres displayed excellent nitrogen compound removal both in model and real fuel, there was a need to improve the adsorbent adsorption capacity for N-compounds in fuel through the fabrication of imprinted nanofibers. Molecularly imprinted poly-2-(1H-imidazol-2-yl)-4-phenol nanofibers was prepared by electrospinning of 2-(2’-hydroxy-4-ethenylphenyl) imidazole (PIMH) in the presence of various organonitrogen compounds. These imprinted nanofibers show selectivity for various target model nitrogen-containing compounds with adsorption capacities of 11.7 ± 0.9 mg/g, 11.9 ± 0.8 mg/g and 11.3 ± 1.1 mg/g for quinoline, pyrimidine and carbazole, respectively. Adsorption selectivity increased in the order of pyrimidine (αi-r = 258.8) ˃ quinoline (αi-r = 235.5) ˃ carbazole (αi-r = 168.2). It further displayed excellent nitrogen removal in real fuel. The use of polybenzimidazole (PBI) nanofibers showed selective adsorption of organonitrogen compounds as imprinted sorbent also displayed high selectivity for their target model nitrogen-containing compounds with adsorption capacities of 11.4 ± 0.4 mg/g, 11.9 ± 0.2 mg/g and 10.9 ± 0.7 mg/g for quinoline, pyrimidine and carbazole respectively. Adsorption selectivity increased in the order of pyrimidine (αi-r = 241.5) ˃ quinoline (αi-r = 237.6) ˃ carbazole (αi-r = 170). Thermodynamic parameters obtained from isothermal titration calorimetry (ITC) revealed that quinoline-PIMH/PBI and pyrimidine-PIMH/PBI interactions are exothermic in nature, while carbazole-PIMH/PBI is endothermic in nature. DFT calculations indicated that π-π interactions/stacking and hydrogen bond interactions took place between N-compounds (carbazole, quinoline and pyrimidine) and adsorbent (PIMH and PBI). A significant reduction in the quantity of nitrogen containing compounds in hydrotreated fuel was observed (peak area reduction) when adsorbents (PIMH and PBI) was employed, however, the complex nature of organonitrogen compounds in fuel complicate the structure/function approach on MIPs for targeting these unwanted compounds.

These imprinted nanofibers show selectivity for various target model nitrogen-containing compounds with adsorption capacities of 11.7 ± 0.9 mg/g, 11.9 ± 0.8 mg/g and 11.3 ± 1.1 mg/g for quinoline, pyrimidine and carbazole, respectively. Adsorption selectivity increased in the order of pyrimidine (αi-r = 258.8) ˃ quinoline (αi-r = 235.5) ˃ carbazole (αi-r = 168.2). It further displayed excellent nitrogen removal in real fuel. The use of polybenzimidazole (PBI) nanofibers showed selective adsorption of organonitrogen compounds as imprinted sorbent also displayed high selectivity for their target model nitrogen-containing compounds with adsorption capacities of 11.4 ± 0.4 mg/g, 11.9 ± 0.2 mg/g and 10.9 ± 0.7 mg/g for quinoline, pyrimidine and carbazole respectively. Adsorption selectivity increased in the order of pyrimidine (αi-r = 241.5) ˃ quinoline (αi-r = 237.6) ˃ carbazole (αi-r = 170). Thermodynamic parameters obtained from isothermal titration calorimetry (ITC) revealed that quinoline-PIMH/PBI and pyrimidine-PIMH/PBI interactions are exothermic in nature, while carbazole-PIMH/PBI is endothermic in nature. DFT calculations indicated that π-π interactions/stacking and hydrogen bond interactions took place between N-compounds (carbazole, quinoline and pyrimidine) and adsorbent (PIMH and PBI). A significant reduction in the quantity of nitrogen containing compounds in hydrotreated fuel was observed (peak area reduction) when adsorbents (PIMH and PBI) was employed, however, the complex nature of organonitrogen compounds in fuel complicate the structure/function approach on MIPs for targeting these unwanted compounds.

- Description: The diamondback moth, Plutella xylostella (L.) (Lepidoptera: Plutellidae), is an important pest of cruciferous crops worldwide. The prolonged use of synthetic chemical insecticides as a primary means of control has resulted in the development of resistance in pest populations. In addition, the pest has also evolved resistance to the bacterial insecticidal protein of Bacillus thuringiensis which is also widely used as a method of control. Baculoviruses are considered as effective alternatives to conventional methods of control when incorporated into integrated pest management (IPM) programmes. These viruses target the larval stages of insects, are generally host-specific and are safe for use in the environment. This study aimed to isolate a baculovirus from a laboratory-reared P. xylostella colony, characterise it genetically and then evaluate its virulence against neonate and fourth instar larvae. A laboratory colony of P. xylostella was established using pupae and asymptomatic larvae collected from a cabbage plantation outside Grahamstown in the Eastern Cape province of South Africa. The colony flourished in the laboratory due to prime conditions and availability of food. The duration of development from egg to adult was determined by observation and imaging of the various life stages. The mean developmental time from egg to adult was observed to be 14.59 ± 0.21 days. The population of the insects increased rapidly in number leading to overcrowding of the insect colony, and hence appearance of larvae with viral symptoms. Occlusion bodies (OBs) were extracted from symptomatic larval cadavers and purified by glycerol gradient centrifugation. Analysis of the purified OBs by transmission electron microscopy revealed the presence of a granulovirus which was named PlxyGV-SA. The virus isolate was genetically characterised by restriction endonuclease analysis of the genomic DNA, and PCR amplification and sequencing of selected viral genes. The complete genome sequence of a Japanese P. xylostella granulovirus isolate, PlxyGV-Japan, has been deposited on the GenBank database providing a reference strain for comparison with DNA profiles and selected gene sequences of PlxyGV-SA. BLAST analysis of the granulin gene confirmed the isolation of a novel South African PlxyGV isolate. Comparison of the restriction profiles of PlxyGV-SA with profiles of PlxyGV-Japan and other documented PlxyGV profiles obtained by agarose gel electrophoresis revealed that PlxyGV-SA is a genetically distinct isolate. The data obtained from the sequencing and alignment of ecdysteroid UDP-glucosyltransferase (egt), late expression factor 8 (lef-8) and late expression factor 9 (lef-9) genes with those of PlxyGV-Japan also showed that PlxyGV-SA is a genetically different isolate. In order to determine the biological activity of PlxyGV-SA against neonate and fourth instar P. xylostella larvae, surface dose bioassays were conducted. The median lethal concentration of the virus required to kill 50% (LC₅₀) and 90% (LC₉₀) of the larvae was estimated by feeding insects with a range of doses. In addition, the time to kill 50% of the larvae (LT₅₀) was determined by feeding insects with the LC₉₀ concentration. Larval mortality was monitored daily until pupation. The data obtained from the dose response assays were subjected to probit analysis using Proban statistical software. The time response was determined using GraphPad Prism software (version 6.0). The LC₅₀ and LC₉₀ values for the neonate larvae were 3.56 × 10⁵ and 1.14 × 10⁷ OBs/ml respectively. The LT₅₀ was determined to be 104 hours. The neonate larvae were found to be more susceptible to infection than the fourth instar larvae with the same virus concentration. The concentrations used for the neonate larvae assay did not have a significant effect on the fourth instar as no mortality was recorded. This is the first study to describe a novel South African PlxyGV isolate and the results suggest that PlxyGV-SA has significant potential for development as an effective biopesticide for the control of P. xylostella in the field.

- Description: The unique historical stressors linked to South Africa’s apartheid legacy, continues to manifest in the form of economic exclusion, social exclusion, inequality and poverty, with parents being subjugated to service users and extenders rather than included as service advocates, particularly in the child justice system. Furthermore, policies and practices do not include, engage and support parents on an intra and interpersonal level. Parents of children in conflict with the law, experience their children’s charge or arrest as well as their subsequent journey through the child justice system as a crisis resulting in their need for emotional, informational, practical and professional support during the child justice process. The similarities and differences between the contexts of child protection and child justice in supporting parents illuminates the existing gaps in child justice legislation, policy and practice resulting in a lack of support for parents during the child justice process. In the Children’s Act 38 of 2005, it is recognised that parents have a legal responsibility towards their children and that in fulfilling this responsibility parents can access support services to assist them when they face challenges in fulfilling this responsibility. In contrast, despite 80 percent of children in conflict with the law being released into parental care and parents expressing the need for support in fulfilling their parental responsibility, in this regard the Child Justice Act 75 of 2008 fails to make provision for parents to access support services. The child justice system’s narrow focus on parents as service extenders contributes to parents’ being excluded from targeted support services resulting in parents’ support needs not being addressed. The lack of programmes and services aimed at supporting parents highlight the need for coordinated services that address the multiple stressors parents are exposed to. To this end, this study was aimed at coconstructing a practice model for supporting parents of children in conflict with the law. The theoretical lenses employed in the current study namely; the Ecological systems model and the Buffering effect model describes the various systems parents need support from and the type of support they need from their family, community and professionals. Guided by a qualitative approach, the present study integrated applied research, in particular intervention design and development with participatory action research as it allowed systematic collaboration during the research process to ensure rigour. This study involved participants from two research sites namely, the Nerina One- Stop Child Justice Centre in Port Elizabeth and the Reception, Assessment and Referral office at the Uitenhage magistrates’ court. Employing a non-probability purposive sampling method, this study facilitated the participation of parents of children in conflict with the law and child justice officials who met the inclusion criteria, in the co-design and development of a practice model for supporting parents of children in conflict with the law. Participants assumed an expert and collaborative role, which enabled the co-construction of knowledge, meaning and innovation of the practice model. Qualitative data collection methods namely, twelve focus groups and thirty two participant observations, were used to explore, co-construct, describe and design a practice model for supporting parents of children in conflict with the law during the child justice process. Thematic analyses was employed to condense the data, search for codes, categories, themes, relationships and patterns in the data. Due to the research approach and design, data analysis was ongoing and informed design and development of the practice model. Based on the thematic analysis and synthesis both descriptive and analytic themes emerged. To ensure trustworthiness, this study employed various strategies to strengthen commitment, rigour, transparency and coherence. In addition, the participative research process, the inclusion of multiple forms of qualitative inquiry and the significance of the study contributed to the validity and quality of the study. Ethical considerations applicable to the study included participants’ voluntary participation, their informed consent and ensuring participants’ privacy or maintaining confidentially. Various strategies were employed to prevent or minimise risk to participants. The findings showed that formal sources of support, in particular, offer opportunities for parents to access individual and family counselling, parenting advice, and peer support. The study also highlighted the importance of recognising parents as a subsystem in the child justice system offers potential opportunities for inclusion of parents as co-facilitators of parenting programmes or support groups, as peer supporters during the child justice process. Parents’ inclusion as a partner in the child justice system is highlighted as an opportunity for parents to be able to vi participate in child justice fora, oversight committees and accreditation committees to influence policy, services and budget allocations for services to support parents of children in conflict with the law. This study’s contribution to the existing body of knowledge is an integrated, multidisciplinary, multi-phase co-constructed practice model that would enable inclusion of, and support for, parents of children in conflict with the law prior to, during and after the child justice. The co-constructed practice model (a) involves a continuum of parent-centred support for and inclusion of parents prior to, during and after the child justice process; (b) advances an inclusive and collaborative child justice system that views parents as important stakeholders in determining the type of services they need and being involved in developing practice; and (c) promotes parents as equal partners in decision making and policy making to influence legislation, policy and practice in the child justice system.

- Description: The increased incidence of children committing crime and the realisation that the existing legislature dealing with offenders failed to cater for the rights and needs of child offenders gave rise to the introduction of the Child Justice Act 75 of 2008. This Act enables the South African criminal justice system to deal with children in a manner appropriate to their developmental stage. One of the initiatives introduced by the Act is termed ‘diversion’, where children are diverted from the criminal justice system into restorative developmental programmes, offered by organisations such as NICRO (National Institute for Crime Prevention and the Reintegration of Offenders). Their parents or guardians are tasked with the responsibility of monitoring their compliance with the diversion order in terms of Section 24(5) of the aforementioned Act. The monitoring responsibility assigned to the parents of diverted adolescents prompted the research question and aim of this study, namely to explore parents’ experiences in monitoring their adolescents’ compliance with diversion orders and to identify service needs in supporting parents in fulfilling their role as stipulated in the Act. This was a qualitative study that was exploratory-descriptive and contextual in nature. A non-probability purposive sampling technique was employed to identify the parents or guardians of adolescents aged 14 to 17 years that had been diverted to NICRO between June 2011 and June 2012. Individual semi-structured interviews were conducted with the selected parents, and the data collected was analysed using thematic data analysis. The trustworthiness of the research process and the findings was enhanced by employing a variety of data verification strategies. This research contributes to a greater understanding of parents’ monitoring experiences of their adolescents’ compliance with diversion orders. The study revealed that most parents experienced their role as an additional responsibility; they needed access to counseling and information on the child justice process.

- Description: The fresh hake processing lines at Seavuna fishing company in Mossel Bay are not consistently achieving their volume output standards and this is resulting in higher processing costs and loss of processing opportunities. The company’s senior management are concerned about this trend and require a complete review of the effectiveness of the resources deployed on the lines. This with the view of establishing the causes of poor process volume output. In order to resolve the process inefficiency challenges mentioned, this study used both empirical and time studies to investigate the effectiveness of the company’s resources directly deployed in the processing unit. The study focused on investigating the human factor, machinery and equipment, the environment and the current efficiency standards. Relevant literature in the field of process efficiency improvement was consulted to assist in identifying factors that are known to cause process inefficiencies, and also to establish which improvement techniques would be relevant in correcting the situation. From the Literature reviewed, it was evident that a ‘one size fits all’ solution to resolving inefficiencies is almost non-existent and that a solution that is relevant to the problem is more effective. In addition, a benchmarking exercise was also done to establish how Seavuna’s current volume output standards fair against its major rivals. Once data from both studies were collected, the results were analysed using the some of the basic quality tools. Thereafter, lean manufacturing principles were used to attempt to resolve the current efficiency challenges. The study recommended that the company construct a business strategy and a corresponding organisational culture to direct its continuous improvement interventions. The use of strategic quality planning would go a long way in assisting the company to execute some of the interventions recommended.

- Description: This thesis examines the events that took plac,e. in the Northern Frontier District I North Eastern Province of Kenya hetween the late nineteenth century and 1968. After 1900 the imposition of colonial policies impacted on the socio-economic and political structures of the Somali people. This thesis also examines the nature of Somali resistance l\P- to the late 1920s when Somali society was finally pacified. It further examines colonial policies such as the creation of the Somali-Galla line in 1919, the separation of the J uhaland region from the Kenya Colony in 1926 and the Special District Ordinance of 1934. Between 1946 and 1948 the British Government through its Foreign Minister, Ernest Bevin, attempted to unify Somali territories in the Horn of Africa and this raised Somali hopes of uni fication. The Bevin Plan collapsed because of the opposition of the United States, the Soviet Union, the French and Ethiopian leaders. Similar hopes of NFD Somali unification were raised hetween 1958 and 1963 because of the unification of the former British Somali land and Italian Somaliland. Due to the imminent end of British colonial rule in Kenya, the NFD Somali leaders demanded secession from Kenya to join up with the nascent Somali republic. But the NFDSomali hopes of unification with the Somali Repuhlic were dashed by 1964 because of the same opposition provided by the United States, the French and the Ethiopians. The British Government were all along half-hearted towards Somali unification attempts even though the field administrators adopted a pro-Somali attitude to the issue. In the early 1960s, however, the NFD Somali leaders were faced with the additional opposition of the new KANU government in Kenya. In 1964 the failure of the NFD Somalis to secede from Kenya led to the guerrilla war, what the Kenyan government called the 'shifta movement', that engulfed the North Eastern Region until 1968 when the Arusha Memorandum of Understanding was signed between the Kenyan and the Somali Governments. The signing of the Arusha Memorandum of Understanding by the Kenyan and Somali Governments did not satisfy· the NFD Somalis hopes of joining the Somali Republic. The main conclusion of this thesis is that the N FD Somalis, except for few collahorators, did at no time, whether in the colonial or post-colonial eras, accept heing in Kenya. By the late 1960s the prospects of NFD Somalis unifying with the Somali Republic were, in view of the forces arrayed against the Somali secessionist movement, slim; and they have remained slim since then.
