Investigating the cooling rate of cane molasses as quenching medium for 0.61% C high carbon steels

The effect of cooling rate of cane molasses as quenching medium for 0.61% C high carbon steels was investigated. Samples of high carbon steel were spheroidized annealed and then machined prior to the hardening process. Molasses solution of viscosity equals to that of engine oil was prepared by adding water. The samples were normalized and then austenitised at 800oC and soaked for 40 minutes and then quenched in water, engine oil, raw molasses and the prepared molasses solution. Cooling rate curves of all the quenching media used were developed. The highest cooling rate of 60oC/s was attained by the prepared molasses solution. Hardness of the test samples was evaluated. The test results obtained show that the highest hardness value (525 HVN) was obtained from the sample quenched in the prepared molasses solution. Microstructures of the various samples were analyzed using OM and SEM. In all the tests samples martensite structure was observed. It was observed that the prepared molasses solution has higher severity of quenching than that of engine oil but lower than that of water. The research showed that cane molasses can harden high carbon steel without cracking the component in the same way as engine oil, hence, molasses could be a very good alternative to engine oil for use as quenching medium

Social Media in Relation to Cooperate Social Responsibility in Fast Food Industry

This paper focuses on analyzing the role of social media (Facebook, Twitter, Google+,Youtube) with regards to corporate social responsibility (CSR), specifically in the fast food industry. The objectives are to identify the use of social media platforms by fast food restaurants, identify if social media integrate corporate social responsibility in their business thereby limiting marketing of unhealthy meals on their websites, and lastly, to find out if marketing of fast food products on social platforms affect users, especially the young people between the age of 15 to 25. The study analyzed and monitored 70 fast food restaurants and their social media activities. 63 0ut of 70 were found to have at least three social media platforms where they promote their products to end users and none of the restaurants have any restriction in marketing any kind of product using social media. Results from questionnaire survey also found that many social media users get adverts from fast food restaurants with 13.85% being affected to buy the food most times and 47.69% sometimes. 81.54% of the participants also agreed that social media can do a great job in limiting the free marketing of unhealthy products by fast food restaurants.

Performance Analysis of Intelligent Computational Algorithms for Biomass Higher Heating Value Prediction

 Higher heating value (HHV) is an essential parameter to consider when evaluating and choosing biomass substrates for combustion and power generation. Traditionally, HHV is determined in the laboratory using an adiabatic oxygen bomb calorimeter. Meanwhile, this approach is laborious and cost-intensive. Hence, it is essential to explore other viable options. In this study, two distinct artificial intelligence-based techniques, namely, a support vector machine (SVM) and an artificial neural network (ANN) were employed to develop proximate analysis-based biomass HHV prediction models. The input variables comprising ash, volatile matter, and fixed carbon were paired to form four separate inputs to the prediction models. The overall findings showed that both the ANN and the SVM tools can guarantee accurate prediction in all the input combinations. The optimal prediction performances were observed when fixed carbon and volatile matter were paired as the input combination. This combination showed that the ANN outperformed the SVM, having presented the least root mean squared error of 0.0008 and the highest correlation coefficient of 0.9274. This study, therefore, concluded that the ANN is more preferred compared to SVM for biomass HHV prediction based on the proximate analysis
