Download or read book The Pearl Oyster written by Paul Southgate and published by Elsevier. This book was released on 2011-08-19 with total page 589 pages. Available in PDF, EPUB and Kindle. Book excerpt: Contrary to a generally held view that pearls are found by chance in oysters, almost all are now produced from farms. This book is a comprehensive treatment of all aspects of the biology of pearl oysters, their anatomy, reproduction, genetics, diseases, etc. It considers how they are farmed from spawning and culturing larvae in hatcheries to adults in the ocean; how various environmental factors, including pollution affect them; and how modern techniques are successfully producing large numbers of cultured pearls. This is the ultimate reference source on pearl oysters and the culture of pearls, written and edited by a number of scientists who are world experts in their fields. - Comprehensive treatment of pearl oyster biology and pearl culture - Written by the top world authorities - Highly illustrated and figured - Of practical relevance to a broad readership, from professional biologists to those involved in the practicalities and practice of pearl production

Available in PDF, EPUB and Kindle. Book excerpt: Large-scale poverty reduction depends on the effective empowerment of poor people themselves. This publication sets out a conceptual framework that can be used to monitor and evaluate empowerment programmes, based on papers written by practitioners and researchers in a wide variety of fields, including economics and political science, sociology and psychology, anthropology and demography. These papers draw on research and practical experience at different levels, from households to communities to nations and in various regions of the world.

Download or read book Introduction to Public Key Infrastructures written by Johannes A. Buchmann and published by Springer Science & Business Media. This book was released on 2013-11-19 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: The introduction of public key cryptography (PKC) was a critical advance in IT security. In contrast to symmetric key cryptography, it enables confidential communication between entities in open networks, in particular the Internet, without prior contact. Beyond this PKC also enables protection techniques that have no analogue in traditional cryptography, most importantly digital signatures which for example support Internet security by authenticating software downloads and updates. Although PKC does not require the confidential exchange of secret keys, proper management of the private and public keys used in PKC is still of vital importance: the private keys must remain private, and the public keys must be verifiably authentic. So understanding so-called public key infrastructures (PKIs) that manage key pairs is at least as important as studying the ingenious mathematical ideas underlying PKC. In this book the authors explain the most important concepts underlying PKIs and discuss relevant standards, implementations, and applications. The book is structured into chapters on the motivation for PKI, certificates, trust models, private keys, revocation, validity models, certification service providers, certificate policies, certification paths, and practical aspects of PKI. This is a suitable textbook for advanced undergraduate and graduate courses in computer science, mathematics, engineering, and related disciplines, complementing introductory courses on cryptography. The authors assume only basic computer science prerequisites, and they include exercises in all chapters and solutions in an appendix. They also include detailed pointers to relevant standards and implementation guidelines, so the book is also appropriate for self-study and reference by industrial and academic researchers and practitioners.
