Options and Strategies for Balanced Development for Liveable Cities: An Epilogue

This chapter provides a snapshot of what is covered in the preceding chapters on options and strategies for balanced development leading to liveable cities. The chapters are organized under nine sections, including peri-urbanization; culture and social economy; land use planning; water security; wastewater and irrigation; urban agriculture and food security; impact of climate change and adaptation; legal, policy and institutional framework; and integrated urban development. The chapters under these sections cover a broad range of issues for the planning of future cities and peri-urban regions with respect to (1) balanced urban development policies and institutions for future cities; (2) understanding the effects of land use change, population increase, and water demand for the liveability of cities; (3) long-term planning needs and transboundary approaches to ensure secured future for generations ahead; and (4) strategies for optimal land, water, and energy uses for viable and liveable cities. The book emphasizes integrated planning for future development of liveable, resilient, and sustainable cities and peri-urban areas

Paramagnetic structure for the soliton of the 30∘30^\circ partial dislocation in silicon

Based on ab initio calculation, we propose a new structure for the fundamental excitation of the reconstructed 30$^\circ$ partial dislocation in silicon. This soliton has a rare structure involving a five-fold coordinated atom near the dislocation core. The unique electronic structure of this defect is consistent with the electron spin resonance signature of the hitherto enigmatic thermally stable R center of plastically deformed silicon. This identification suggests the possibility of an experimental determination of the density of solitons, a key defect in understanding the plastic flow of the material.Comment: 5 pages, 4 figure
