Crystal growth, casting, soldering, welding, high-energy surface treatment, nuclear safety systems and geophysical flows are just a few examples where solidification and convection occur together. These processes are interactive on micro- and macroscales: flow affects the distribution of heat and species and hence the freezing process, while solidification evolves flow boundaries, as in crusting, for example, and hence can radically alter the convection. Mathematical modellers, experimentalists and applied scientists were invited to this colloquium with the aim of consolidating our understanding of such interactions, of identifying key outstanding issues, and of developing new approaches in this important area of fundamental research. Both invited and contributed papers focus on both fundamental and technologically relevant problems.

David S. Riley's interest in the research and subsequently the history and methodology of homeopathic drug provings began with his medical school training in 1979 and a residency in Internal Medicine. He was exposed to homeopathy in 1988 followed by study at the Hahnemann College of Homeopathy in Albany, California. He has investigated the interplay between contemporary research methods and the research methods associated with homeopathic drug provings. Dr Riley has developed research tools for data collection, symptom selection criteria and blinding; primarily to address the risk of bias.The homeopathic drug provings published here are the result of this work. For the 3rd edition twelve homeopathic drug provings, conducted by a number of internationally renowned proving directors, have been added. These homeopathic drug provings all follow good clinical practice (GCP) research guidelines and incorporate the guidelines suggested by Dr Samuel Hahnemann more than 200 years ago.
