Lignocellulosicbiomass fly ash (LcBFA) gotten from Berlinia Grandiflora (Vahl) Hutch. & Dalziel (Ububa tree, in common Nigerian parlance) was used to stabilise a soil sample characterised as A-2-7 soil. The LcBFA was added to the lateritic soil at varying proportions of 0%, 10%, 20%, 30% and 40%. Chemical characterization of the LcBFA was obtained; particle size analysis, moisture content test, atterberg limit test, proctor compaction test, California bearing ratio value (CBR) test, and specific gravity test were conducted on the soil sample. The results showed an increase in plasticity, an increase in maximum dry density, a decrease of optimum moisture content and an increase in CBR value. It was concluded that LcBFA lacks the potential of serving as a pozzolan.

The need to integrate processes within enterprise between ERP and shop-floor level and also across enterprise boundaries for optimal and collaborative environment, to highlight the importance of real time information access in order to make decision and to show the importance of predictive maintenance in a production environment prompted this research. Information obtained from industries were analyzed. The results however, showed that industry 4.0, if fully adopted would increase production of goods and services and also save time consumed during production stage.

The sole aim was to compare the performance of a solar hybrid air-conditioner with that of the conventional split-unit airconditioning systems in the market today. From the experiments conducted, the room temperature of a solar hybrid air conditioner was found to be :
