The reclusive and endangered snow leopard, is one of the many fascinating species covered in this guide. The World of Wild Cats, edited by world-famous naturalist Jeff Corwin, teaches about the way wild cats evolved, how they are built and how they behave, reproduce and survive in different habitats around the world. It also highlights some of the most familiar and unique species found worldwide, their current status, what to do if you encounter a wild cat in the wild and what you can do to help to conserve and protect these spectacular creatures. This folding pocket guide is the ideal reference for cat-lovers and teachers alike. Made in the USA.
This is the first of two volumes that review, for the first time, all major aspects of photorefractive effects and their applications. Photorefractive effects in electro-optic crystals are based on optically induced space-charge fields which ultimately alter the refractive indices by the electro-optic Pockels effect. The fundamental phenomena leading to photoinduced changes of refractive index, the materials requirements and experimental results on a variety of photorefractive materials are discussed and the most recent theoretical models describing these phenomena are presented. Interest in photorefractive materials has increased in recent years mainly because of their potential for nonlinear optical devices and for optical signals processing applications. Most of these applications are reviewed in the second volume devoted to this topic. The contributions to these two volumes are written by experts on each topic and are intended for scientists and engineers active in the field and for researchers and graduate students entering the field. Over 300 references to original papers on photorefractive and associated phenomena are cited.
