Author:Mwakikunga, Bonex W; Hillie, KTDate:Sep 2011This chapter introduces some facts about graphene, how it was discovered, how it has been realised by several approaches and how to get its identity. Its identity is seen either through cross-sectional TEM or through its unique signature in ...Read more
Author:Fasiku, F; Owonubi, S; Mukwevho, E; Aderibigbe, B; Sadiku, E; Lemmer, YolandyDate:Jun 2019Over the years, many different materials, e.g., titanium (Ti) and its alloys, have been used in biomedicine for several purposes. A common application of such materials is seen in their usage as implants. However, quite a number of graphene-based ...Read more
Author:Van der Walt, PJDate:1949The problem of predicting practical yield and ash values when washing coal in a specified type of washer based on float and sink data obtained from laboratory tests is discussed in this report.Read more
Author:Vorster, J; Van Heerden, Renier PDate:Mar 2015Graphical passwords schemas are becoming more main-stream. There are many different approaches to graphical passwords, each with its own drawbacks and advantages. There has been many studies to suggest that graphical passwords should be ...Read more
Author:Govender, Natasha; Claassens, JDate:Nov 2010For a robotic platform to be able to assist/interact in human environments, the platform must be able to perform some fundamental tasks. This includes interacting with humans by grasping or releasing objects as or when required by the human. ...Read more
Author:Greben, HA; Sigama, NJDate:Nov 2008The biological sulphate removal technology requires carbon and energy sources to reduce sulphate to sulphide. Plant biomass, e.g. grass, is a sustainable source of energy when cellulose is utilised during anaerobic degradation, producing ...Read more
Author:Unsted, ADDate:Feb 1997Prior to the introduction of gravimetric dust sampling, konimeters had been used for dust sampling, which was largely for control purposes. Whether or not absolute results were achievable was not an issue since relative results were used to ...Read more
