- Description: Technology has become important in the business environment as it ensures that a business is competitive and it also drives the business processes. However, in the era of mobile devices, easy access to the internet and a wide variety of other communication mechanisms; the security of the business from a technological perspective is constantly under threat. Thus, the problem that this research aims to address is that there is currently a lack of understanding by SMMEs in protecting their stored sensitive information assets. This study intends to assist small businesses, such as those within the Small Medium and Micro Enterprises (SMME) on how to protect and secure information while it is in storage. SMMEs usually do not have available resources to fully address information security related concerns that could pose a threat to the well being and success of the business. In order to address the problem identified, and assist SMMEs with better protecting their stored information assets, the outcomes of this research is to develop guidelines to assist SMMEs in protecting stored sensitive information assets. Through the use of a qualitative content analysis, a literature review, a number of information security standards, best practices, and frameworks, including the ISO27000 series of standards, COBIT, ITIL, and various NIST publications were analysed to determine how these security approaches address security concerns that arise when considering the storage of sensitive information. Following the literature analysis, a survey was developed and distributed to a wide variety of SMMEs in order to determine what their information security requirements might be, as well as how they address information security. The results obtained from this, coupled with the literature analysis, served as input for the development of a number of guidelines that can assist SMMEs in protecting stored sensitive information assets.

- Description: Organic azides are important in the synthesis of many target molecules of great use in fine chemical and pharmaceutical production. The use of this class of compounds is however limited due to their hazardous nature and many safety concerns, as they are highly exothermic. Micro reactors can handle exotherms extremely well, due to the inherent high surface area to volume ratio, unlike the conventional batch process. This dissertation therefore aims to investigate the safe application of micro reactors in acyl azide chemistry.With this in mind, Chapter 1 provides a comprehensive background on organic azides, reaction calorimetric studies, flow chemistry technology (micro reactors) and their theoretical advantages. This chapter also discusses the preparation of organic azides in continuous flow systems and scaling up in continuous flow systems. Chapter 2 illustrates and discusses multivariate optimisation of benzoyl azide synthesis as a model reaction, synthesis of other acyl azides using the model reaction optimised conditions and multistep synthesis of carbamates, amides and amines in continuous flow systems via the Curtius rearrangement of benzoyl azide formed in situ from benzoyl chloride and sodium azide. The chapter also discusses process hazards analysis and evaluation of benzoyl azide synthesis and decomposition using calorimetric studies. It also investigates and discusses the effects of different mixing regimes and channel sizes on scale up. Chapter 3 has comprehensive experimental details for the whole dissertation with Chapter 4 providing the concluding remarks and future work recommendations.
