CONDUCTION MECHANISM IN FERRITES
Ceramic-like ferromagnetic materials, which are mainly composed of ferric oxide, α-Fe2O3 are called "ferrites". Although the saturation magnetization of ferrites is less than half that of ferromagnetic alloys, they have advantages Applicability at higher frequency Lower price Greater heat resistance Higher corrosion resistance.The practical applications of ferrites have been expanded by completely utilizing these advantages.Magnetite, Fe3O4, which is a natural mineral, is a genuine ferrite, and it is said that ancient people had recognized its magnetism and it was used as a mariner's compass in China for more than two millennia ago. The importance of ferrites was brought to public attention after 1950's because new applications such as radio, television, microwave devices, carrier telephony and computer-circuitry were rapidly expanding. At the same time, physicists, and electronic engineers throughout world were interested in the magnetism and high frequency application of ferrites.
MAGNETISATION IN TERNARY SPINEL FERRITES
The word "magnet" refers to the material having both directive and attractive property. The magnet with its two such distinct and significant properties have attracted common man as well as researcher because of its obvious applications in various fields like electronic, electrical telecommunication, biomedical, power, food, automobile, construction, recording media and computer industries. Research in this area has gained momentum since 1914. It focuses on synthesis, characterization, functionalization of the properties of these materials for betterment of human life in the society.

Advanced Study in the History of Modern India 1707-1813
An analytical and critical account of the political history of early modern India from 1707 to 1813. The narrative shatters the contention of contemporary European writers that it was 'the dark age' of Indian history, characterised by 'political anarchy and misgovernment', until the British brought it under their sway. The main thesis of the author is that the period was marked by two distinct phases; the first phase, which lasted from 1707 to 1760, saw the rapid disintegration of the Mughal power and its replacement by the Maratha hegemony. Meanwhile, the English traders turned colonialists, after consolidating their hold along the Indian seacoasts and conquest of 'Carnatic' and Bengal, cha...

Clearly structured throughout, the main body of the book is divided by pollutant type with a chapter devoted to each group of pollutants. Each chapter follows a similar format to facilitate comparison and discussion. For each pollutant, the authors describe the sources, pathways, environmental fate and sinks as well as known toxicological effects. Importantly, the second chapter on heavy metals and other inorganic substances deals with trace element deficiencies which can have serious problems for human health. Some rocks and soils are ...
