This textbook is aimed at graduate and upper undergraduate students studying materials science and metallurgy. It comprehensively covers the topic of microstructural characterization and includes an emphasis on Fourier analysis and Fourier transformation, electron diffraction, electromagnetic waves and electron waves, lens parameters, transmission electron microscopy, optical microscopy and scanning electron microscopy. The author has included pedagogical features such as end-of-chapter exercises and worked examples with varying degrees of difficulty to augment learning and self-testing....

Plant virus and sub-viral pathogens pose severe constraints to the production of wide range of economically important crops worldwide. The crops raised both through true seed and vegetative propagated materials are affected with number of virus and virus-like diseases. The virus may enter into plants through seed planting materials or by vectors. Once the virus is in the field, it multiplies and spreads following definite patterns depending upon the nature of the vector and agro-meteorological conditions. Disease free crops and plants are great economic and social importance in feeding the...
