The rare earth elements have had and still have a unique and important impact on our lives. The unfilled 4f electronic structure of the rare earth elements makes them have special properties in luminescence, magnetism and electronics, which could be used to develop many new materials for various applications such as phosphors, magnetic materials, hydrogen storage materials and catalysts [1]. Rare-earth-doped luminescent materials (i.e. phosphors) are known to emit at distinct and different wavelengths in the electromagnetic spectrum and have been extensively used in color cathode ray tubes (CRT), tri-phosphor fluorescent lamps, X-ray intensifying screens and recently developed vacuum mercury-free lamps, as well as various types of displays such as plasma display panels, field emission displays and projection TVs [2].
Reservation or affirmative action is a hugely controversial policy in India. While constitutionally mandated and with historians, political scientists and social activists convinced of its need, many resist it and consider it as compromising 'merit' and against the principle of equality of opportunity. In These Seats Are Reserved, Abhinav traces the history and making of the reservation policy. How were groups eligible for reservations identified and defined? How were the terms 'depressed classes' and 'backward classes' used in British India and how have they evolved into the constitutional concepts of 'Scheduled Castes', 'Scheduled Tribes', and 'Other Backward Classes' in the present day? T...
This book is mainly based on the latest research results and applications of phenolic and polyphenolic compounds. Phenolic compounds, ubiquitous in plants, are an essential part of the human diet and are of considerable interest due to their antioxidant properties and potential beneficial health effects. These compounds range structurally from a simple phenolic molecule to complex high-molecular-weight polymers. There is increasing evidence that consumption of a variety of phenolic compounds present in foods may lower the risk of health disorders because of their antioxidant activity. When added to foods, antioxidants control rancidity development, retard the formation of toxic oxidation pro...
Written by outstanding experts in the colloids field, this book deals with the recent developments in the synthesis, modification, utilization and application of colloids. The types covered range from metal nanoparticles through to inorganic particles and polymer latexes. Strategies for their modification to impart new properties will be outlined and ordered assemblies derived from colloid particles and some applications for colloids are shown. A multidisciplinary audience spread throughout academia and industry alike will certainly appreciate this first concise collection of knowledge in book form for this topic.
This book is mainly based on the latest research results and applications of sorghum food in human diet and gets good health benefits from it. Sorghum has several medical properties and cures several diseases as mentioned in the index. Sorghum grains can be converted in various indigenous food products and include in the daily human diet. Some of the specific sorghum components when added to foods, antioxidants control rancidity development, retard the formation of toxic oxidation products, maintain nutritional quality and extend the shelf-life of products. Sorghum diet is useful for curing cancer, diabetic disorder and so many other aliments also. In addition, sources of other beneficial components of sorghum are also discussed in detail. Sorghum is the only one cereal sustain under drought situation and gives definite yield under rain-fed condition. During current climate change situation sorghum is the best drought resistant crop for getting definite amount of grain yield.
This book presents a comprehensive overview of the bioactive potential, food applications, and health benefits of coloured cereal grains for researchers carrying out innovative studies.
Co-operation means working together. The principles of co-operation are as old as human society. Co-operation means living, thinking and working together. Formation of social groups is the outcome of reflexive co-operation, while the life of ants, bees, waps, lines etc., provide the best examples of instinctive co-operation. From the most primitive to the most sophisticated community, through the world, we come across some or the other form of co-operation among the people living in particular area or region it may be for some agricultural operations or for some social, economic or political activity.
This book is a good introductory work to nanoparticle technology. It consists of nine complementary chapters that can be read independently. This book covers promising nanoparticles fabrication technologies with a focus on scalable processes. Integration of nanoparticles into 2D and 3D structures are covered in detail. The most promising applications of nanoparticles in the energy, optoelectronic and biomedical sectors are summarized and discussed. Current issues and challenges related to nanoparticles production and utilisation are also discussed in the book. Complete and simple overview of the field Contains practical examples that makes the book also accessible for industrialists, engineers and managers Chapters can be read relatively independently so experienced researchers can go directly to the them of interest Advantages, drawbacks and challenges are described with practical examples
By an Indian politician during, 1918-1933.
