Electromagnetic Fields and Life
Author: A. Presman
Publisher: Springer Science & Business Media
ISBN: 1475706359
Category : Science
Languages : en
Pages : 349
Book Description
A broad region of the electromagnetic spectrum long assumed to have no influence on living systems under natural conditions has been critically re-examinjld over the past decade. This spectral region extends from the superhigh radio frequencies, through de creasing frequencies, to and including essentially static electric and magnetic fields. The author of this monograph, A. S. Presman, has reviewed not only the extensive Russian literatur!;"l, but also al most equally comprehensively the non-Russian literature, dealing with biological influences of these fields. Treated also is literature shedding some light on possible theoretical foundations for these phenomena. A substantial, rapidly increaSing number of studies in many laboratories and countries has now clearly established bio logical influences which are independent of the theoretically pre dictable, simple thermal effects. Indeed many of the effects are produced by field strengths very close to those within the natural environment. The author has, even more importantly, set forth a novel, imaginative general hypothesis in which it is postulated that such electromagnetic fields normally serve as conveyors of information from the environment to the organism, within the organism, and among organisms. He postulates that in the course of evolution or ganisms have come to employ these fields in conjunction with the well-known sensory, nervous, and endocrine systems in effecting coordination and integration.

Electromagnetic Field Interaction with Transmission Lines
Author: Farhad Rachidi
Publisher: WIT Press
ISBN: 1845640632
Category : Science
Languages : en
Pages : 289
Book Description
The evaluation of electromagnetic field coupling to transmission lines is an important problem in electromagnetic compatibility. Traditionally, use is made of the TL approximation which applies to uniform transmission lines with electrically small cross-sectional dimensions, where the dominant mode of propagation is TEM. Antenna-mode currents and higher-order modes appearing at higher frequencies are neglected in TL theory. The use of the TL approximation has permitted to solve a large range of problems (e.g. lightning and EMP interaction with power lines). However, the continual increase in operating frequency of products and higher frequency sources of disturbances (such as UWB systems) makes that the TL basic assumptions are no longer acceptable for a certain number of applications. In the last decade or so, the generalization of classical TL theory to take into account high frequency effects has emerged as an important topic of study in electromagnetic compatibility. This effort resulted in the elaboration of the so-called 'generlized' or 'full-wave' TL theory, which incorporates high frequency radiation effects, while keeping the relative simplicity of TL equations. This book is organized in two main parts. Part I presents consolidated knowledge of classical transmission line theory and different field-to-transmission line coupling models. Part II presents different approaches developed to generalize TL Theory.

Power Frequency Magnetic Fields and Public Health
Author: William F. Horton
Publisher: CRC Press
ISBN: 9780849394201
Category : Science
Languages : en
Pages : 292
Book Description
The prospect that electromagnetic fields (EMFs) may foster disease is an alarming thought-one which raises such questions as: What are these invisible forces? How are they produced? Is there conclusive evidence that they are harmful to the human body? How do we protect ourselves against possible harm from them? This book addresses these and other questions about magnetic fields, bringing together in a single reference source the scientific background, current status of health research, and means to reduce the impact of EMFs in our environment. Important information is provided for developing policies and procedures related to human interaction with magnetic fields. The authors describe the concept of prudent avoidance, emphasizing its value as a tool in the design, construction, and valuation of homes, offices, retail facilities, and factories. The book provides theory, computer simulation results, measured data, and recommendations for magnetic field management, all of which are useful as a power system design and construction resource. The authors have compiled an impressive summary of the studies, findings, and reports done in the past 15 years in the areas of human health effects which might be attributed to exposure to power frequency magnetic fields. Wherever appropriate throughout text, the authors provide examples to illustrate concepts and include end-of-chapter exercises (with solutions) to help readers solidify their understanding of the material presented. Originally designed as a textbook, this is also an excellent reference in the areas of environmental engineering, city and regional planning, and electrical engineering.

Thermal and non thermal effects of electromagnetic fields in bio-systems
Author: André Bellossi
Publisher: Lulu.com
ISBN: 1471052494
Category : Science
Languages : en
Pages : 239
Book Description
This book presents physical models, backed by experimental results, explaining the behavior of living matter in relation to electromagnetic (EM) fields ranging from quasi-stationary state to optical range. The ability of very low frequency EM fields to cure diseases (e.g. respiratory infection) is addressed. The bacteria destruction by non-thermal effects of low frequency electric fields is explained with the proton nuclear resonance and the DNA half-wave resonance. The microtubule instabilities are studied. Explosion of bacteria with acoustic resonance is also modeled. Centimeter and millimeter-waves effects are discussed. Clues about interaction with the human brain are given. Effects of a 60 GHz field on cellular physiology are presented as well as on mice nerve system. A cell membrane is modeled in near IR to UV ranges. The capacity of cells to move towards an IR source is explained. Finally, explanation of cancer mechanisms of the human skin is proposed with ultra-weak photon energy.

Plasma Physics of the Local Cosmos
Author: National Research Council
Publisher: National Academies Press
ISBN: 9780309092159
Category : Science
Languages : en
Pages : 100
Book Description
Solar and space physics is the study of solar system phenomena that occur in the plasma state. Examples include sunspots, the solar wind, planetary magnetospheres, radiation belts, and the aurora. While each is a distinct phenomenon, there are commonalities among them. To help define and systematize these universal aspects of the field of space physics, the National Research Council was asked by NASA's Office of Space Science to provide a scientific assessment and strategy for the study of magnetized plasmas in the solar system. This report presents that assessment. It covers a number of important research goals for solar and space physics. The report is complementary to the NRC report, The Sun to the Earthâ€"and Beyond: A Decadal Research Strategy for Solar and Space Physics, which presents priorities and strategies for future program activities.
