This book focuses on direct nitrogenation strategies to incorporate one or more N-atoms into simple substrates especially hydrocarbons via C H and/or C C bond cleavage, which is a green and sustainable way to synthesize nitrogen-containing compounds. The book consists of seven chapters demonstrating interesting advances in the preparation of amines, amides, nitriles, carbamides, azides, and N-heterocyclic compounds and illustrating the mechanisms of these novel transformations. It offers an accessible introduction to nitrogenation reactions for chemists involved in N-compound synthesis and...

Blauert's and Xiang's "Acoustics for Engineers" provides the material for an introductory course in engineering acoustics for students with basic knowledge in mathematics. In the second, enlarged edition, the teaching aspects of the book have been substantially improved. Carefully selected examples illustrate the application of acoustic principles and problems are provided for training.

"Acoustics for Engineers" is designed for extensive teaching at the university level. Under the guidance of an academic teacher it is sufficient as the sole textbook for the subject. Each chapter...

This book introduces the components and principles of the common ballast management systems. The working principles of different filtration, cleaning and sterilizing equipment are also introduced. The calculation norm of the construction design and the calculation method of simulation are described. Besides, different aspects of system management are analyzed. The principle of various detecting sensors, the hardware of control system and the design method of human–computer interface are respectively introduced. Last but not least, the maintenance and management of ballast water...

Welcome to Encounters, a groundbreaking Chinese language program that features a dramatic series filmed entirely in China.
