Valency and Molecular Structure, Fourth Edition provides a comprehensive historical background and experimental foundations of theories and methods relating to valency and molecular structures. In this edition, the chapter on Bohr theory has been removed while some sections, such as structures of crystalline solids, have been expanded. Details of structures have also been revised and extended using the best available values for bond lengths and bond angles. Recent developments are mostly noted in the chapter on complex compounds, while a new chapter has been added to serve as an introduction to the spectroscopy of complex compounds. Other topics include the experimental foundation of the quantum theory molecular-orbital method ionic, hydrogen, and metallic bonds structures of some simple inorganic compounds and electronic spectra of transition-metal complexes. This publication is a useful reference for undergraduate students majoring in chemistry and other affiliated science subjects..
Marine Auxiliary Machine: Sixth Edition explains the correct operation and maintenance of marine auxiliary machinery. The book discusses topics such as the arrangements of the engine and boiler room pipes and fittings and pumps compressors and separators and heat exchangers - its types, control of temperature, and maintenance. The book also talks about other machineries such as diesel engines, steam turbines, propellers, and gears refrigeration and air conditioning systems deck machinery and safety equipment. The text is recommended for engineers in ships who would like to know more about the auxiliary machines onboard ships, how they are operated, and the principles behind them..
Metal Cutting is a guide that discusses the process of metal cutting and its different techniques. The book first gives a short history and introduction to metal cutting, and then discusses the operations and terminologies used in metal cutting the essential features of metal cutting and the forces involved. The use of heat, the cutting tool materials, the machinability of different metals and alloys, and the use of coolants and lubricants in metal-cutting machines are also explained. The text is recommended for metalworkers and engineers, especially those who are new to the industry, as this book serves as a handy reference for this craft..
