Taschenbuch. Zustand: Neu. Neuware -The increasing demand for fish and shrimp as cheap and healthy food has promoted worldwide development of intensive aquaculture, which simultaneously increased the occurrence of several diseases among the farmed species. Fish and shrimp diseases pose severe economic losses and are considered as the major bottleneck for the aquaculture production and development. In this manner, there is a prime necessity for the understanding of diseases and their control which is outlined in this book which gives a new insight for the prevention of infections and their transmissions in aquaculture to support sustainable aquaculture production and product trade.Books on Demand GmbH, Überseering 33, 22297 Hamburg 72 pp. Englisch.

From the foreword: The Andaman and Nicobar Islands, popularly known as 'Bay Islands' are situated in the Bay of Bengal, mid way between peninsular India and Mayanmar, spreading like a broken necklace in the North-South direction. These islands are located between 6 45 and 13 41 N latitudes and 92 12 and 93 57 E longitudes. There are 572 islands in all which lie in North-South direction in the Bay of Bengal. The total geographic area of Andaman and Nicobar Islands is 8249 km2, of which Andaman group covers 6408 km2 while Nicobar group covers 1841 km2. The maximum altitude of these islands is 732m at Saddle Peak in North Andaman. Their geology is mainly limestone, sandstone, and clay. There are two volcanic islands, namely Narcondum Island and Barren island. The former is now apparently extinct while the latter is still active. The climate is typically tropical and is always warm, but with sea-breezes. The tropical hot and humid climate with abundant rains has resulted in very luxuriant and rich vegetation of tropical rain forests. This archipelago is considered as a paradise of biological diversity. Out of 1340 species of birds recorded from Indian subcontinent, 21 per cent are found in Andaman and Nicobar Islands. A total of 284 species of birds belonging to 56 families under 17 orders were reported from A & N Islands. Of the recorded species, 155 species were residents, 58 local migrants, 64 trans-continental migrants, 6 vagrants and one species a straggler. Of the 284 species of birds, 105 are endemics at species and subspecies levels. Of the 142 endemic bird species of the Indian subcontinent, 28 are distributed in Andaman and Nicobar Islands. Though the A & N Islands form only 0.25 per cent of the landmass of India, they support 12 per cent of the endemic avifauna.

Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - This book surveys state-of-the-art optimization modeling for design, analysis, and management of wireless networks, such as cellular and wireless local area networks (LANs), and the services they deliver. The past two decades have seen a tremendous growth in the deployment and use of wireless networks. The current-generation wireless systems can provide mobile users with high-speed data services at rates substantially higher than those of the previous generation. As a result, the demand for mobile information services with high reliability, fast response times, and ubiquitous connectivity continues to increase rapidly. The optimization of system performance has become critically important both in terms of practical utility and commercial viability, and presents a rich area for research. In the editors' previous work on traditional wired networks, we have observed that designing low cost, survivable telecommunication networks involves extremely complicated processes. Commercial products available to help with this task typically have been based on simulation and/or proprietary heuristics. As demonstrated in this book, however, mathematical programming deserves a prominent place in the designer's toolkit. Convenient modeling languages and powerful optimization solvers have greatly facilitated the implementation of mathematical programming theory into the practice of commercial network design.These points are equally relevant and applicable in today's world of wireless network technology and design. But there are new issues as well: many wireless network design decisions, such as routing and facility/element location, must be dealt with in innovative ways that are unique and distinct from wired (fiber optic) networks. The book specifically treats the recent research and the use of modeling languages and network optimization techniques that are playing particularly important and distinctive roles in the wireless domain.
