This book aims at enhancing the understanding of topics in crystallography through solving numerical problems. Designed into nine chapters on major topics in crystallography, the book deals with more than 600 carefully selected solved examples, problems, and multiple-choice questions. Unit cell composition, construction and calculations, Miller indices, structure factor calculations, and X-ray diffraction methods are some of the many useful topics discussed in this book. Each chapter begins with a brief theoretical explanation of the topic followed by solved numerical examples for further clarity on the subject. The topic "crystallography" is interdisciplinary in nature. Its rudimentary knowledge, therefore, is essential to the beginners in physics, chemistry, mathematics, molecular biology, geology, metallurgy, and particularly materials science and mineralogy. This book also is of immense value to senior undergraduate and graduate students of physics, chemistry, and other basic sciences.

This book presents a comprehensive theoretical basis of symmetry representations of molecular vibrations, matrix representation of symmetries, and the elements of group theory that are relevant to other symmetry elements/operations, crystallographic and molecular point groups. The book helps understand the reducible and irreducible representations of symmetry matrices and then derive the normal modes of vibration of different molecules by using suitable techniques independently. Targeted to graduate students and researchers, this book aims not only to derive the normal modes of vibration of any given molecule themselves but also compares and verifies them with the experimentally found modes by using IR and Raman-related techniques. For the first time in the crystallographic history, this book presents the group multiplication tables of all 32 point groups in both international and Schoenflies notations.

This book contains the findings of a study which was conducted for 60 days at the pond complex of the Freshwater Station of Bangladesh Fisheries Research Institute located about one kilometer away west of the Bangladesh Agricultural University, Mymensingh. The research was carried out to compare the performance of different nursing practices of giant freshwater prawn (Macrobrachium rosenbergii) post-larvae (PLs). Three treatments such as only fertilizers (T1), fertilizers with 5% supplementary feed (local feed) (T2) and 10% commercial feeds (T3) were applied in the nursing system of prawn PLs in earthen pond. The results showed that growth and survival in prawn nursery was better in commercial feed than only fertilizers and fertilizers with local feeds. So, this book will be helpful for those who are interested in prawn post larvae rearing, feeding and management in nursery ponds.
