Electric Fuses
Fundamentals and new applications
Nigel Nurse
The Institution of Engineering and Technology, 2022
Fuses are designed to operate when over-currents, large and small, occur within electrical equipment; they thus interrupt the flow of current, preventing damage. They are needed for various power electric systems, for stationary and automotive applications, as well as power grid components like PV systems and distribution lines. Different types of equipment and voltages require special fuses, and their behaviour must be understood to guarantee correct choice and safe operation.

Soviet Natural Resources in the World Economy
Edited by Robert G. Jensen, Theodore Shabad, and Arthur W. Wright
University of Chicago Press, 1983
Russia is a huge storehouse of natural resources, including oil, gas, and other energy sources, which she can trade with the rest of the world for advanced technology and wheat. In this book, leading experts evaluate the Soviet potential in major energy and industrial raw materials, giving special attention to implications for the world economy to the end of the twentieth century.

The authors examine the mineral and forest resources that the Soviet Union has developed and may yet develop to provide exports during the 1980s. They discuss the regional dimension of these resources, especially in Siberia and the Soviet Far East; individual mineral raw materials, such as petroleum, natural gas, timber, iron ore, manganese, and gold; and finally the role of raw materials in Soviet foreign trade.

The authors, representing the United States, Canada, and Great Britain, are primarily geographers, but they include economists, political scientists, and a geologist. Their work is based on primary sources (for most of these reports, current information is no longer being released to researchers) and on interviews with Soviet officials.
