Sommario/riassunto |
|
South Africaís provincial education departments have been reduced to provincial administrations, for reasons that include the powerful role national government plays in delivering education services. This book looks in detail at education spending and asks: Can we afford to maintain administrations that cannot possibly change the course of poor quality education and engineer a brighter future for our poor and deprived learners? The authors believe this question and the future role of provincial education departments need to be discussed, openly and publicly, without delay. |

Sommario/riassunto |
|
This book represents a detailed and systematic account of the basic principles, developments and applications of the theory of nucleation.The formation of new phases begins with the process of nucleation and is, therefore, a widely spread phenomenon in both nature and technology. Condensation and evaporation, crystal growth, electrodeposition, melt crystallization, growth of thin films for microelectronics, volcano eruption and formation of particulate matter in space are only a few of the processes in which nucleation plays a prominent role.The book has four parts, which a |
