With every increasing population especially in developing countries, the adverse impact on forest, land resources, water resources, energy resources, and mineral resources is obvious. Today, the pollution level has reached a point where flora and fauna are threatened for existence. Under the circumstance, it is essential to integrate Environmental Protection with development and hence there is urgent and pressing need to educate Engineers to this end. Because of this reason, a subject entitled 'Environmental Science' has been introduced in core programme in Engineering Education leading to B.Tech/B.E. degree. It is expected that engineering graduates, who will shoulder the responsibilities of development tomorrow, should also be fully aware of environmental protection.

The present book covers the following topics: Introduction to Environmental Sciences; Environment and Development; Water Pollution-Sources, Standards and Control; Air Pollution-Sources, Standards and Control; Noise Pollution-Sources, Standards and Control; Socio-economic and Socio-cultural Aspects of Environmental Degradation; Planned Industrial Development; Environmental Impact Assessment; Renewable Energy Sources; Conservation of Energy; Environmental Management; Engineering Ethics; Energy and Environment; Environmental Protection Through Recycling etc. Certainly, this will prove an authoritative source book.

Encyclopaedia of Nanotechnology is one of its kinds in terms of coverage, scope, elaboration, usefulness and futuristic perspective. Nanotechnology is now a rapidly growing field of research and development that is cutting across many traditional boundaries. This technology has the ability to control or manipulate on the atomic scale. Nano is a prefix meaning one billionth (1/1,000,000,000). This is why; Nanotechnology overlaps with a wide range of the existing sciences. Subjects that seem at present to have the most direct and constructive involvement with Nanotechnology are: Optical and Quantum Physics; Molecular Biology; Biomedical Engineering (through genetics and Microbiology); Electrical Engineering (through MEMS systems); Software Engineering (through AI, Communication and Information Systems). The applications of nanotechnology are near limitless, but the main focus seems to be on its use in medical applications. That seems to be what's driving the research, since it would give us to opportunity to cure most diseases, even possibly eliminating the concept of natural death. There are so many other applications, however, ranging from mundane to incredibly profound. Other applications include ultra-fast & high memory capacity computers, highly advanced communication systems, advanced display technology, advanced biological imaging, stem-cell engineering, medical diagnostic tools, sensors for airborne pollutants energy storage materials, photovoltaic cells, fuel cells, polymer nanocomposites, super-tough nanocoatings, landmine detectors, and thousands more. Nanotechnology has, therefore, become the hottest topic of discussion in the scientific world, media, government circles and corporate circles. Although it is a field that has already seen its share of hype, there is a general consensus that over the long term, nanotechnology is likely to reconfigure everything.

International Encyclopaedia of Science and Technology is an outstanding attempt to keep pace with recent developments and expanding vocabularies in all branches of science and technology. This encyclopaedia is more or less encyclopedic in its contents and style of representation. Throughout the process of compilation a sincere effort has been made to include all those entries which serve as a ready reference for undergraduate and postgraduate students of science, technology and engineering. This may also prove useful for those appearing for competitive examinations, research scholars, teachers and authors. The entries included in this set have been written in a clear and elegant style to provide both straight forward definition and invaluable background information. At certain suitable places the line diagrams have been included wherever the meaning of a term can be best conveyed by means of a diagram. An extensive cross reference system makes the reader to place the each entry into a broader scientific context. The main aim maintained in compiling this set is to sustain the interests of readers while enriching their vocabulary and comprehension of technical their vocabulary and comprehension of technical terms and expressions of various branches of science.

This set will prove to be of immense value to the students of science and engineering, and to scientists, technologists and research scholars working on science projects. It is expected that many readers will use this set not merely for reference but also as a readable material. The editing of this set has been based on the vast research and teaching experience of editors who have been actively engaged in the different aspects of science and technology. Their valuable experience has been carefully condensed in compiling this set.

India boasts of rising itself to the status of a few big nations, which are advanced in science and technology. India made most of the long strides after independence. Once, crumbled and crushed India is now an invigorated and ignited soul yearning for capturing the space. As for India's progress in science, it has been excelling in software development and nuclear sciences. Besides, Indian universities and educational institutes are now attracting people from across the world.

Specifically focused on the Indian science and technology, this modest work is a fruition of concerted efforts and research based analysis and data. Written in easy and lucid language, its organization has been made very naturally and orderly.

A must read for enthusiasts of science and technology and an important tool of information for the general readers.
