Hardcover. Zustand: New. This book provides engineers with the necessary resources to employ essential physics principles in their work. By having a firm grasp on these basic concepts, engineers will be better equipped to comprehend the natural world and its laws, enabling them to design and create novel technologies and products that improve our everyday lives.Ultimately, understanding physics allows us to gain insights into the physical world around us, from the smallest subatomic particles to the vast reaches of the universe.…

Hardcover. Zustand: New. Physics is a fundamental branch of science that aims to explain the nature of reality by quantifying the interactions between matter and energy. Its scope extends to other natural sciences like biophysics, astronomy, and chemistry, enabling scientists to understand the fundamental questions of the universe. This field of science has been evolving for over 2,000 years, with philosophers and scientists, including Aristotle, Isaac Newton, and Marie Curie, using physics to comprehend the world around us. The book discussed in the second sentence offers a new and innovative approach to theoretical reasoning in physics, highlighting real-world applications that researchers use to expand our understanding of the subject. The book showcases landmark experiments and theories that were once revolutionary, providing insight into how and why physics has transformed over time.…

Hardcover. Zustand: New. 1st Edition. In recent past, exotic vegetables like broccoli, red cabbage, Savoy cabbage, Chinese cabbage, celery, gherking etc. have been introduced and their adaptability studies have been undertaken in different parts of the country. These Vegetables are getting increasing demand in the five star cultures of the cosmopolitan cities. They generally require cool temperature, however, agro climatic conditions prevailing in several parts of north-western Himalayas of J&K, Himachal Pradesh and Kumaon and Grahwal division of Uttarakhand are very favourable for growing these exotic vegetables. This current publication deals about 37 exotic vegetables. It is expected that in near future more research attention will be paid towards advance production and protection technology, genetic improvement and application of biotechnological tools to address the several complex issues of different exotic vegetables grown across the country. I assure to the readers that new and enlarged edition of this title will be brought for their reference. (jacket).…

Contents Preface 1 Introduction 2 Materials and methods 3 Observation 4 Discussion References From the introduction Silk is a protein fibre produced by sericigenous insects belonging to family Saturniidae superfamily Bomycoidea order Lepidoptera which is one of the finest and most beautiful natural fibres of the world and is said to be the queen of the fibres It is yarn of life extruded by that unassuming caterpillar into a continuous filament It is secreted from the silk glands of the silkworm Basically there are two proteins which form the silk fibre viz fibroin which constitutes the core of the fibre and sericin a waxy substance which encase the fibroin Silk is as old as that of civilization itself According to available records and antiques of silk articles unearthed by archeologists China is the homeland of silk industry which dates back to at least 5000 years da huan et al For hundreds of years the Chinese guarded the secret of sericulture by imperial law According to popular legend the Chinese dominance of sericulture was weakened when emperor Justinian in the sixth century dispatched several monks on an espionage mission to bring back silkworm eggs from China They brought the eggs back to constentinopole from where it spread to different parts of the world In India sericulture is as old as Indian culture Datta silk especially tasar silk has been mentioned in the old epics like Ramayana and Mahabharata According to the Indian legend sericulture was introduced about 2000 years ago the wild silkmoth producing yellow silk fibre was very popular from the ancient time Mukherjee though according to European scholars Chinese bi voltine silk was introduced in India in 140 BC  435 pp.…

From the Preface Aim of this book is to bridge the gap between traditional materials on pollution and quantitative and technical aspects that are the essence of most advanced environmental science. The book will also provide necessary informations on environmental chemistry and physics that are prerequisite for the mechanism of working of pollutants. Various chapters of the book covering water pollution air pollution soil pollution noise pollution and radiation describe in details about the sources and effects of pollutants. Control measures to mitigate pollution are added at the end of each chapters. Special emphasis has been laid on topics of international and global concern such as greenhouse effect stratospheric ozone depletion photochemical smog aerosols and acid rains and are discussed well. This book will satisfy the needs of undergraduate and postgraduate students of environmental biology. This book has been checked thoroughly and corrected to the best of our knowledge however errors and suggestions brought to our notice will be appreciated. 222 pp.…

Hardbound. Zustand: As New. New. Contents Preface. 1. Introduction i. Ecology. ii. Insects. 2. Classification of insects. 3. Origin of insects. 4. Insects one of the most successful group. 5. Aquatic insects i. Fresh water habitat. ii. Marine water habitat. iii. Orders of aquatic insects. iv. Adaptation in aquatic insects. v. Life cycle in aquatic insects. vi. Filter feeding in aquatic insects. This is the happiest moment for the authors to present Ecology of Aquatic Insects to readers of this discipline. Study of any organism without considering its ecology is not complete as no organism can be separated from its environment. About 75% of earth's surface is covered by water which is source of life on earth. It is the medium within which all aspects of ecosystem co exist both living and non living. Insects have adopted themselves to occupy almost every conceivable ecological niche in on or above the earth. They are all around us occupying our houses puncturing our skin consuming our food and clothing. There is scarcely any place on the earth that is not home to atleast one kind of insects. They endure all extremes of environment and are the most successful group of animals from Protozoa to mammals. This is an attempt to provide distinct advantage to its user (undergraduate postgraduate and life science students and also the researchers who are engaged in deciphering the mystery of aquatic ecology) towards better understanding of relation between insects and aquatic environment. 240 pp. …
