Sommario/riassunto |
|
This reference on current VB theory and applications presents a practical system that can be applied to a variety of chemical problems in a uniform manner. After explaining basic VB theory, it discusses VB applications to bonding problems, aromaticity and antiaromaticity, the dioxygen molecule, polyradicals, excited states, organic reactions, inorganic/organometallic reactions, photochemical reactions, and catalytic reactions. With a guide for performing VB calculations, exercises and answers, and numerous solved problems, this is the premier reference for practitioners and upper-level student |

They change color depending on their mood. They possess uniquely adapted hands and feet distinct from other tetrapods. They feature independently movable eyes. This comprehensive volume delves into these fascinating details and thorough research about one of the most charismatic families of reptiles-Chameleonidae. Written for professional herpetologists, scholars, researchers, and students, this book takes readers on a voyage across time to discover everything that is known about chameleon biology: anatomy, physiology, adaptations, ecology, behavior, biogeography, phylogeny, classification, and |

conservation. A description of the natural history of chameleons is given, along with the fossil record and typical characteristics of each genus. The state of chameleons in the modern world is also depicted, complete with new information on the most serious threats to these remarkable reptiles. |

The Decroux Sourcebook is the first point of reference for any student of the 'hidden master' of twentieth century theatre. This book collates a wealth of key material on Etienne Decroux, including:an English translation of Patrice Pezin's 'Imaginary Interview', in which Decroux discusses mime's place in the theatre.previously unpublished articles by Decroux from France's Bibiothèque Nationale. essays from Decroux's fellow innovators Eugenio Barba and Edward Gordon Craig, explaining the synthesis of theory and practice i |
