Book Description
Recent emphasis upon the importance of the physical environment has made science and the public even more cog nizant of the many components of the biosphere. While much attention has been given to ionizing electromagnetic stimuli which causes blatant and unalterable changes in biological systems, relatively little research has been concerned with those electromagnetic signals whose frequencies overlap with time-varying processes in living organisms. Extremely low frequency (ELF) electromagnetic fields can occur as waves between about I Hz to 100 Hz or as short pulses within this range of very low frequency (VLF) and higher frequency sources. The natural occurrence of ELF signals is associated with weather changes, solar disturbances and geophysical ionospheric perturbations. Man-made sources have also been reported. Certain physical properties of ELF signals make them excellent candidates for biologically important stimuli. Unlike many other weather components, ELF signals have the capacity to penetrate structures which house living organ isms. ELF wave configurations allow long distance propaga tional capacities without appreciable attenuation of inten sity, thus making them antecedent stimuli to approaching weather changes. Most importantly, ELF signals exhibit the frequencies and wave forms of bio-electrical events that occur within the brain and body. Thus resonance inter actions between animal and nature become attractive possi bilities.

Book Description
The objective of this book is to present in a concise manner what is actually known at the present time about biological effects of time invariant, low frequency and radio frequency (including microwave) electric and magnetic fields. In reviewing the vast amount of experimental data which have been obtained in recent years, the authors tried to select those results that are, in their opinion, of major importance and of lasting value. In discussing mechanisms of interaction of electromagnetic fields with living matter they have tried to differentiate between what is clearly established, what is suggested by available evidence without being convincingly proven, and what is conjecture at the present time.

Book Description
The first edition of this book has been recognized as the standard reference on biological effects of electric and magnetic fields from DC to microwaves. But much has changed in this science since the book's original publication in 1986. With contributions from eighteen leading researchers, this latest edition includes authoritative discussions of many new developments and will quickly become the new, must-have resource handbook. Dielectric properties of biological tissue are thoroughly examined, followed by chapters on physical mechanisms and biological effects of static and extremely low frequency magnetic fields. New chapters on topics that were treated very briefly in the first edition now receive extensive treatment. These topics include electric and magnetic fields for bone and soft tissue repair, electroporation, and epidemiology of ELF health effects. The chapter on computer methods for predicting field intensity has been substantially revised to describe new numerical techniques developed within the last few years and includes calculations of power absorbed in the human head from cellular telephones. The chapter discussing experimental results on RF interaction with living matter now contains information on effects of very high power, very short duration pulses. A new appendix on safety standards is based on the latest publications of governmental, as well as quasi-governmental organizations (such as the U.S. Council on Radiation Protection) in the United States, Europe, and Australia. With all its revisions, this updated version of the CRC Handbook of Biological Effects of Electromagnetic Fields provides the most comprehensive overview available of this rapidly changing science.

Book Description
ARCHIVE COpy DO NOT REMOVE The public in industrialized countries shows a mounting concern about biological effects of electrical and magnetic fields. As a result, experimental studies on this subject are being published in increasing numbers throughout the world. Prof. H. L. Konig, of the Technical University of Munich, West Germany, a leading expert and pioneer in this field, has written an authoritative text in a lucid style which makes the material also accessible to lay readers. The book describes the effects of natural as well as artificial electromagnetic energies covering the en tire measurable frequency range from the highest frequencies, x-rays, through microwaves, radio waves, and finally extremely low frequency (ELF) waves. Cit ing the evidence from scientific studies in various countries, Konig also appraises the biologic effects of microwaves and high tension power lines, which have become controversial issues in recent years. Other contributions to the book have been made by Prof. Albert P. Krueger, University of California, Berkeley, on air ionization effects and by the mete orologist Walter Sonning on biometeorology, documenting the influence of atmo spheric electrical currents on health and disease. Moreover, the late Dr. Siegnot Lang, a former coworker of Dr. Konig, has contributed to this book.

Book Description
This book is the first in a new series entitled ''Advances in Circadian Physiology." Our aim in this and subsequent volumes is to document and critically analyze the state of knowledge on biological clocks, circadian rhythms and their applications to human health, safety, performance and productivity. In the past twenty years, scientists have uncovered an elegant system of biological clocks in the brain that govern the daily rhythms of sleep and alertness, hormone levels and temperature and a myriad other aspects of body function. From the first identification of the suprachiasmatic biological clock in the early 1970s, this field of research has exploded in information and implication. These biological clocks, so perfectly attuned to the pace of a bygone era, are the root cause of the human fatigue, error, accidents and reduced productivity precipi tated by the around-the-clock challenges of today's industry and society. Research on these clocks offers the promise of fundamental solutions which can help the human race adjust physiologically to the technology-paced world we have created.

Book Description
International Series of Monographs in Electromagnetic Waves, Volume 3: Electromagnetic Waves in Stratified Media provides information pertinent to the electromagnetic waves in media whose properties differ in one particular direction. This book discusses the important feature of the waves that enables communications at global distances. Organized into 13 chapters, this volume begins with an overview of the general analysis for the electromagnetic response of a plane stratified medium comprising of any number of parallel homogeneous layers. This text then explains the reflection of electromagnetic waves from planar stratified media. Other chapters consider the oblique reflection of plane electromagnetic waves from a continuously stratified medium. This book discusses as well the fundamental theory of wave propagation around a sphere. The final chapter deals with the theory of propagation in a spherically stratified medium. This book is a valuable resource for electrical engineers, scientists, and research workers.
