Comprehensive comparisons show that good agreements were obtained between calculated and experimental values not only for the diffusion coefficients, but also for diffusion/solidification processes resulting from interdiffusion, such as the Kirkendall shift and solidification curve.

South African trends in the transition to sustainability are discussed for each of five stages in the life cycle of the built environment: urban planning; project design; the manufacture of building materials and products; construction and maintenance and management. When these trends are evaluated in terms of the economic, social, and environmental components of sustainability, a number of issues become apparent. Differing forms of environmental sustainability are evident in all five stages of the life cycle, although environmental factors should not be overlooked in 'fast-track' development, driven as it is by a sense of urgency to create economic growth. Economic sustainability is most readily observed in the construction phase through the empowerment of emerging contractors, employment-intensive practices, and training initiatives for
