My introduction to the fascinating phenomena associated with detonation waves came through appointments as an external fellow at the Department of Physics, University College of Wales, and at the Department of Mechanical Engineering, University of Leeds. Very special thanks for his accurate guidance through the large body of information on gaseous detonations are due to Professor D. H. Edwards of University College of Wales. Indeed, the onerous task of concisely enumerating the key features of unidimensional theories of detonations was undertaken by him, and Chapter 2 is based on his initial draft. When the text strays to the use of we, it is a deserved acknow- ledgement of his contribution. Again, I should like to thank Professor D. Bradley of Leeds University for his enthusiastic encouragement of my efforts at developing a model of the composition limits of detonability through a relationship between run-up distance and composition of the mixture. The text has been prepared in the context of these fellowships, and I am grateful to the Central Electricity Generating Board for its permission to accept these appointments.
The four companion volumes on Dynamic Aspects of Detonations and Explosion Phenomena and Dynamics of Gaseous and Heterogeneous Combustion and Reactive Systems present 111 of the 230 papers given at the Thirteenth International Colloquium on the Dynamics of Explosions and Reactive Systems held in Nagoya, Japan. These books embrace the topics of explosions, detonations, shock phenomena, and reactive flow, as well as the gasdynamic aspects of nonsteady flow in combustion systems, the fluid mechanics aspects of combustion, and diagnostic techniques. Two of the volumes, Dynamics of Gaseous Combustion (Vol. 151) and Dynamics of Heterogeneous Combustion and Reacting Systems (Vol. 152), focus on the processes of coupling the exothermic energy release with the fluid mechanics occurring in various combination processes. The other two volumes, Dynamic Aspects of Detonations (Vol. 153) and Dynamic Aspects of Explosion Phenomena (Vol. 154), address the rate processes of energy deposition in a compressible medium and the concurrent nonsteady flow as it typically occurs in explosion phenomena.
From prolific Irish artist, Mary Murphy, comes a stunning Irish language picture book that will evoke lots of giggles, gurgles and smiles - not to mention kisses - from little babies! Prestigious poet and translator, Gabriel Rosenstock, captures in Irish all the fun, fizz and warmth of Mary Murphy's picture book words in this young, interactive title all about...kissing! Did you know that a giraffe kiss is gentle and tall...like this! *Mwaaaah!* Then there are kisses that are quick and small...others are fizzy and bubbly...some are even long and tooty-tooty! There are SO many different types of kisses, just turn the page to see! This split-page book, with its cast of loveable, cuddly-looking parent-and-child animals is the perfect gift for a new baby or a young family who wish to encourage a love of the Irish language in their child. Pog Mar Seo will be the ninth title translated into Irish for the Walker Eireann list, an initiative which celebrates Walker Book's Irish writers and illustrators, creating perfect books for children. It is a standout, young novelty book with split-pages throughout and a stunning finale spread with glitter foil across the page. Walker Eireann - leabhair le laimhseail go gramhar, i dteanga do chroi.
