The effects of homogeneous-heterogeneous reaction on the fluid flow over a shrinking sheet is examined. A hybrid nanofluid is considered, with alumina and copper as the nanoparticles and water as the base liquid. The governing equations are solved numerically using similarity approach with the help of MATLAB software. Two outcomes are attained for several ranges of the mass flux parameter . The friction factor as well as the concentration gradient enhances in the presence of nanoparticles, but the rate of heat transfer declines. Moreover, the concentration gradient is intensified for larger homogeneous and heterogeneous strength.

This study was conducted to investigate whether excessive workload factor, poor work environment factor, lack of social support factor and shortage of manpower factor will influence work stress among nurses at KPJ Johor Specialist Hospital. In this study, the questionnaire used is adopted from Fitzgibbon (2016), Beh and Loo (2012) and Konstantinos and Christina (2008). The questionnaires were distributed to 80 nurses from Women and Baby Centre Ward and General Ward at KPJ Johor Specialist Hospital by using the convenience sampling technique. The software used to analyse the collected data is SPSS. By using correlation analysis, it is found that there is significance and positive correlation between work stress and the four factors. From the correlation analysis, excessive workload factor (r = 0.553) and shortage of manpower factor (0.564) were the strongest positively related to work stress among KPJ nurses. The multiple regression analysis also used in this study revealed that the four factors are significant in explaining the dependent variable; working stress (F = 11.877, p < 0.05).
