Author:National Building Research InstituteDate:Sep 1981Energy is becoming increasingly expensive. Conservation can offset the increase in energy cost and can therefore be considered a new and can fairly inexpensive source of energy. The following article looks at the ways in which energy savings ...Read more
Author:Kenyon, CP; Roth, Robyn L; Van der Westhuyzen, Christiaan W; Parkinson, CJDate:Mar 2012The kinome is made up of a large number of functionally diverse enzymes, with the classification indicating very little about the extent of the conserved kinetic mechanisms associated with phosphoryl transfer. It has been demonstrated that ...Read more
Author:Naidoo, M; Piketh, SDate:Oct 2015Air quality modelling requires the identification of all relevant sources of emissions and the accurate calculation of the emissions rates. Many of these sources include anthropogenic activities that need to be accounted for in any emissions ...Read more
