Electromagnetic Interaction with Biological Systems


Book Description

Ever since the early 1940's, electromagnetic energy in the nonionizing spectrum has contributed to the enhanced quality of life in a variety of ways. Aside from their well-known roles in communication, entertainment, industry and science, electromagnetic energy has come into wide spread use in biology and medicine. In addition to the intended purposes, these energies produce other effects which have been shown to influence the life processes of living organisms. It is noteworthy that these energies are not only harmless in ordinary quantities but are actually necessary for modern life, indeed without which life as we know it would be impossible. The purpose of this book is to present a succinct summary of the interaction of electromagnetic fields and waves with biological systems as they are now known. The subject matter is interdisciplinary and is based primarily on presentations scheduled for a joint symposium at the XXII General Assembly of the International Union of Radio Science, held in Tel Aviv, Israel from Tuesday, August 25 to Wednesday, September 2, 1987. The symposium was jointly sponsored by the Bioelectromagnetics Society in cooperation with the International Radiation Protection Association. The choice of topics was made to facilitate the application and to stimulate the use of nonioni zing electromagnetic energy in biology and medicine, and to increase the awareness and to promote the consideration of radiation safety by electrical engineers and experimental physicists.




Twentieth Century Physics


Book Description

Twentieth Century Physics, Second Edition is a major historical study of the scientific and cultural development of physics in the twentieth century. This unique three-volume work offers a scholarly but highly readable overview of the development of physics, addressing both the cultural and the scientific aspects of the discipline. The three volumes deal with the major themes of physics in a quasi-chronological manner. The first volume covers the early part of the century while the second and third volumes discuss more recent issues. In each case, the development of the theme is traced from its inception to the present day. The list of contributors includes Nobel laureates, fellows of the Royal Society, and other distinguished international physicists. Where appropriate, specialists in the history of physics have written their own commentaries, providing a valuable counterpoint to the physicists' perspectives.

Radar for Meteorological and Atmospheric Observations


Book Description

Epoch-making progress in meteorology and atmospheric science has always been hastened by the development of advanced observational technologies, in particular, radar technology. This technology depends on a wide range of sciences involving diverse disciplines, from electrical engineering and electronics to computer sciences and atmospheric physics. Meteorological radar and atmospheric radar each has a different history and has been developed independently. Particular radar activities have been conducted within their own communities. Although the technology of these radars draws upon many common fields, until now the interrelatedness and interdisciplinary nature of the research fields have not been consistently discussed in one volume containing fundamental theories, observational methods, and results. This book is by two authors who, with long careers in the two fields, one in academia and the other in industry, are ideal partners for writing on the comprehensive science and technology of radars for meteorological and atmospheric observations.




Liberia under Samuel Doe, 1980–1985


Book Description

On April 12, 1980, a group of soldiers led by Master Sergeant Samuel K. Doe executed a bloody coup that put an end to the Americo-Liberian minority regime in Liberia, transforming Africa’s first republic into a military dictatorship. In Liberia under Samuel Doe, 1980-1985: The Politics of Personal Rule, Yekutiel Gershoni examines the evolution and effects of Samuel K. Doe’s reign in Liberia. Gershoni shows Doe’s path to absolute power, corruption, and dictatorship and the economic crises and political turmoil that ensued, even after his murder in 1990. Liberia under Samuel Doe also examines the role of the United States as Liberia’s closest ally, detailing how Doe managed to attract American diplomatic and military support due to U.S. interests in the Cold War. Through in-depth research, primary sources, and interviews with diplomats, politicians, and activists, Gershoni carefully details the timeline of Doe’s rise to power and the lasting effects of his dictatorial legacy.
