β-Carotene is the most appropriate and significant precursor of vitamin A. Synthetic carotene supplements have been known to pose a threat to human health, making natural sources such as the indefensible choice for the production and extraction of carotene.

This study considers Blakeslea trispora, a filamentous fungus, as a source of production of carotenoids by fermentation and wet and dry mycelium were used to analyse and obtain better extraction results.

In this study, natural oils such as soy oil and cottonseed oil were incorporated into fermentation media to increase the production of carotene. For the optimization process, Plackett–Burman and one-factor-at-a-time (OVAT) models were identified as being of great value.

OVAT was carried out for corn starch because it plays a major role in the production of carotene and the corn starch at 30 g/L concentration has shown the maximum activity of 3.48 mg/gm. After optimizing process variables, submerged fermentation was eventually carried out under highly controlled media conditions. The resulting product was quantified using UV spectroscopy and extraction of carotene has been observed in the presence of various solvents. Among a range of solvents used, the methylene Di chloride produced-carotene at 86% recovery at a significantly lower temperature of 35°C.

Design of experiments (DOE) is a scientific method for identifying the critical parameters associated with a process and thereby determining the optimal settings for these process parameters for enhanced performance and capability. It is a powerful technique employed in the improvement phase of the Six Sigma methodology as a means to improve process yield, stability, customer satisfaction and reduce process variability which results in high scrap, rework and warranty costs. This paper presents the application of DOE to a spot welding process in order to discover the key process parameters, which influence the tensile strength of welded joints. Statistical analysis was carried out to identify the process parameters, which affect the mean strength and variability in weld strength. The results of the study encouraged the engineering team within the company to extend the application of DOE to other core processes within the business as a process performance improvement technique.

Shainin's variables search methodology (SVSM) is a powerful tool for spotting the key or critical process parameters or variables (such as Red X, Pink X and Pale Pink X) from a large list of process parameters. It has been argued that the variables search methodology developed by Dorian Shainin provides a powerful, yet simple approach that lends itself to easier implementation in an industrial environment. This paper illustrates how SVSM has been employed in identifying the influencing variables that control the joint strength of honeycomb composite tongue and slot joints within an aerospace company. The results of the study have provided the stimulus for the wider application of this approach in other business processes within the company.

The purpose of this paper is to assess the serious corrosion problems of the water injection system on the offshore oil field and to study the type, and effect factors and mechanisms of corrosion on the offshore oil field in order to develop an effective corrosion inhibitor for the sea water injection system.

The corrosion of metal in a water injection system was studied by weight‐loss and electrochemical methods.The effect factors and mechanisms of corrosion on the offshore oil field were proposed from the trend of corrosion.

FeCO₃ is the main corrosion product in the water injection system of the Chengdao Offshore Oil Field. The corrosion rate of coupons in sea water injection systems reaches a maximum peak at a temperature of 50‐60°C. The corrosion rate of coupons exposed in all three water samples increased with an increase in the dissolved oxygen concentration. When the mixed ratio of sea water and produced water and well water is 1:3:1 or 1:2:2, the corrosion rate of carbon steel is lower than is the case in pure water. The electrochemical mechanism of corrosion indicates that corrosion in the well water, produced water, and sea water samples were all controlled by the oxygen absorption process, which controlled the cathodic reaction. The corrosion rate of coupons followed the ranking order: well water; produced water; sea water.

This paper provides the main corrosion product in the water injection system of the Chengdao Offshore Oil Field, and provides new information on the effect factors and mechanisms of corrosion on the offshore oil field.

Higher education institutions (HEIs) have multiple roles including teaching, research and more recently projects for the benefit of local communities. From a management and leadership perspective, the formation and implementation of strategic plans and the collaboration with stakeholders have traditionally been based on formal agreements based on existing operational organizations and structures. Their strategic plans and collaborations with stakeholders are now evolving to become more organic and collaborative. They have become essential participants of the innovation and learning ecosystems and knowledge intensive communities as shown here in the case of Finland and Australia. New businesses and regions, especially in Europe and non-European Union countries such as Australia, are encouraged to identify and develop their own competitive advantages by analyzing their strengths and strategic potential growth areas.

This so-called Smart Specialization (RIS3) strategy brings HEIs together with the local authorities, business companies and civil society to co-operate in order to prioritize research and development (R&D) investment in the region. The need for Smart Specialization also challenges HEIs to rethink their visions and renew the present siloed and closed-ended practices.

This chapter examines and compares the management and leadership of the HEIs as actions are undertaken to effectively lead the Finnish and Australian HEIs toward their visions. These case studies demonstrate approaches which influence good institutional governance and management. It describes how LAB-ammattikorkeakoulu (LAB University of Applied Sciences) in Finland, and Royal Melbourne Institute of Technology in Australia have implemented a RIS3 strategy, notably in health and well-being and agricultural (R&D) projects. These enhance the scope of accountability and participation of stakeholders. The chapter provides practice-based evidence to policy makers in higher education regarding HEIs’ responsible contribution to society.

The purpose of this paper is to investigate the short and long run causal relationship between stock market development and economic growth in sub-Saharan Africa within the period 1990 and 2020.

Using panel data from 1990–2020 obtained from the World Bank development indicators, the study makes use of the autoregressive distributed lag model and the Granger causality and cointegration to analyze the long and short run causal relationship between stock market development and economic growth in sub-Saharan Africa.

The findings unveiled that stock market capitalization had a positive and significant effect on economic growth in the long run and a negative insignificant effect in the short run within the period of 1990–2020 while stock market liquidity measured through total value of shares traded and turnover ratio had a negative and significant effect on economic growth in sub-Saharan Africa within the period of 1990–2020. The Granger causality test showed an inconclusive result between stock market development and economic growth; implying that the authors cannot say if it is stock market development that causes economic growth or it is economic growth that causes stock market development within the period of 1990–2020.

The findings suggest that governments of sub-Saharan African countries should encourage stock market development by implementing favorable rules for companies listing on their stock market, promote stock market integration with world markets to diversify risk, increase public awareness on stock markets, increase investors' confidence level and finally, remove stock market impediments like high taxes, legal and regulatory barriers to its development.

This study contributes to the existing literature by offering a whole new perspective on stock market development and economic growth since its conception in sub-Saharan Africa. Again, contrary to other papers, the study show how stock market development can contribute to the growth of sub-Saharan Africans’ economy.

This paper looks at how the Early Learning Centre have reviewed their relevancy to their customer base and ensured that they have developed a differentiated communications programme to talk to their customers.
