Hardcover. Condición: New. From the preface : "Erstwhile Bihar, lying close to the foot hills of Nepal and covering an area of 1,73,877 sq km, harbours a very rich and diverse flora. Its unique phytogeographical position, topography and good precipitation are some of the important factors which are mainly responsible for high degree of plant diversity. The occurrence of different types of forests, ranging from subtropical to tropical and consequently the establishment of three National Parks and twenty Wildlife sanctuaries in the state, which constitute an important source of germplasm, are of considerable interest. Although the state has been botanically surveyed since 1848 and the Flora was published during 1921-1925 which included Bihar, Orissa and parts of West Bengal, but the complete Flora of Bihar itself is not in hand. Simultaneously, the natural vegetation since Haines' publication has been continuously and increasingly under pressure owing to developmental projects including mining activities and non-judicious exploitation of plant resources. These reasons coupled with the publication of a number of new plant records for the state warrant the need of fresh estimation of current status of floristic account n the state. The present work is an attempt in this direction to provide the status of the Flora of the state. It is hoped that this publication will be highly helpful to the botanists, especially taxonomists, environmentalists, foresters, agriculturists, horticulturists,pharmacologists and planners in their research and management programmes. 777 pp.…

Hardcover. Condición: Very Good. Oversized hardcover, xvi + 818pp, NOT ex-library. Weight 1270g. Previous owner's name covered with a blank sticker, else interior is very good: clean and bright throughout with unmarked text, free of stamps. Firm secure binding; clean outer page edges. Spine and board edges moderately yellowed, boards show regular shelfwear, minor creases to lower spine. Published without a dust jacket. Recent innovations in experimental techniques such as molecular and cluster beam epitaxy, supersonic jet expansion, matrix isolation and chemical synthesis are increasingly enabling researchers to produce materials by design and with atomic dimension. These materials constrained by sire, shape, and symmetry range from clusters containing as few as two atoms to nanoscale materials consisting of thousands of atoms. They possess unique structuraI, electronic, magnetic and optical properties that depend strongly on their size and geometry. The availability of these materials raises many fundamental questions as weIl as technological possibilities. From the academic viewpoint, the most pertinent question concerns the evolution of the atomic and electronic structure of the system as it grows from micro clusters to crystals. At what stage, for example, does the cluster look as if it is a fragment of the corresponding crystal. How do electrons forming bonds in micro-clusters transform to bands in solids? How do the size dependent properties change from discrete quantum conditions, as in clusters, to boundary constrained bulk conditions, as in nanoscale materials, to bulk conditions insensitive to boundaries? How do the criteria of classification have to be changed as one goes from one size domain to another? Potential for high technological applications also seem to be endless. Clusters of otherwise non-magnetic materials exhibit magnetic behavior when constrained by size, shape, and dimension. NanoscaIe metal particles exhibit non-linear opticaI properties and increased mechanical strength. SimiIarly, materials made from nanoscale ceramic particIes possess plastic behavior.

Hardcover. Condición: New. 1st Edition. This book water biology pertains to the aspects of the ecology of surface waters, including rivers and lakes, connected ground waters, flood plains and wetlands. It also focuses on the physico-chemical, biological and microbiological parameters of the water and wastewater. It helps to know about the quality and present status of water. It also deals with the structural and functional interrelationships of organisms of inland waters as they are affected by their dynamic physical, chemical, biotic environments and the impact of human activities on these systems. The book contains 29 chapters that are thoroughly reviewed by the authors and provides ample information on micro-organisms, algae, macrophytes, invertebrates, fish and other vertebrates, as well as those concerning whole systems and related physical and chemical aspects of the environment. Authors took much care in presenting the easiest way to understand the properties of water. The book will be of great help to the students of UG and PG, researchers, policy makers and stakeholders in the field of environment.…
