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

Author:Von Wolff, WTEDate:1969Three coal samples, with abrasiveness indices of 533, 779 and 142 iron eroded, respectively, were heated 350 C in a current of air to remove carbonaceous material.Read more
Author:Mothosi, KL; Chikosha, Silethelwe; Madyira, DM; Chikwanda, Hilda KDate:Jan 2017Manufacturing processes typically produce residual stresses. The residual stresses can be advantageous when they are compressive and detrimental when tensile. In roll compaction of metal powder, similarly to rolling solid metals, substantial ...Read more
Author:Kunstmann, FH; Muller, EFEDate:1957Aluminium oxide , among other substances, is used as a "structural promoter" in iron catalysts. Following method makes possible the determination of the relatively small amounts of aluminium in iron catalysts.Read more
Author:Bandyopadhyay, J; Ray, SSDate:May 2011The poly(ethylene terephthalate)/thermotropic liquid crystal polymer (weight ratio 80:20) blend composites with two different weight percentages of nanoclay were prepared using a twin-screw extruder. The frequency sweep experiments at a ...Read more
Author:Bonapace, AC; Du Toit, PDate:1976This report aims to investigate coal in its various stages of mechanical handling during the processes of winning, preparation and utilization, and how it causes wear of the metal surfaces with which it makes contact. And presents basic ...Read more
Author:Petrick, AJDate:1958'The agreements between the collieries supplying blend coking to Iscor provide for the purchase of this coal in the air-dry condition. Therefore, weight-bridge tonnages must be converted to tons of air-dry coal.Read more
Author:Meintjies, AADate:1971This report contains details regarding the composition of the gaseous decomposition products formed when coal is pyrolysed at a fast rate.Read more
Author:Mahlangu, Vusi J; Ndibewu, PP; Pretorius, Cecilia JDate:Sep 2016The focus of the entire project is to characterize diesel particulate matter from various mining commodities into its respective constituents and to further evaluate and outline the possible identified markers for better health engineering ...Read more
Author:Fakude, PM; Erasmus, C; Taylor, JRNDate:Feb 2006One of the major problems that affect maize quality is insect infestation of stored products. Currently, this problem is controlled by the use of chemical pesticides. Methyl bromide, the pesticide with the widest application, is being phased ...Read more
Author:Gurtunca, RG; Adams, DJDate:Mar 1991In situ measurements and numerical modelling based on elastic theory showed that backfill stresses are considerably higher than originally thought. This has led to a change in understanding of rockmass behaviour. After describing previous ...Read more
