Author:Machete, Fannie; Morakinyo, OMDate:Apr 2017This study presents a characterization framework for energy efficient hotels. It builds on existing frameworks of energy efficiency and the adopted characterization framework advances from the input-output framework. The theoretical framework ...Read more
Author:Dewar, J; Taylor, JRN; Berjak, PDate:Jul 1997The effect of various steeping conditions (time, temperature and aeration) on the quality of sorghum malt for brewing (in terms of diastatic power, free amino nitrogen and hot water extract) was examined. Steeping time and temperature had a ...Read more
Author:Tshilombo, KDate:Feb 2010Nozzle blocking was eliminated by calcium-treated liquid steel through changing the chemical and phase composition of alumina inclusions in aluminium-killed steel. Three different methods were applied to determine the composition of inclusions ...Read more
