Download or read book Ultra and Extremely Low Frequency Electromagnetic Fields written by Vadim Surkov and published by Springer. This book was released on 2014-07-08 with total page 495 pages. Available in PDF, EPUB and Kindle. Book excerpt: The major emphasis of this book is on physical mechanisms and sources of the ULF/ELF natural electromagnetic fields noises. In the course of this text, some of these mechanisms of magnetospheric origin will be treated in detail and others in a more sketchy fashion, while the global electromagnetic resonances excited by lightning activity and other sources are the priority. The interested reader is referred to the books cited in the text for details about the ULF/ELF fields of magnetospheric origin. Much emphasis is put on studies of electromagnetic phenomena caused by rock deformation/fracture including the ULF/ELF effects possibly associated with tectonic activity, earthquakes and other natural disasters. One of the challenges of this research is to fully understand electromagnetic effects and physical processes in the rocks deep in the Earth’s crust.

Download or read book Biological Effects of Power Frequency Electric and Magnetic Fields written by Office of Technology Assessment United S and published by The Minerva Group, Inc.. This book was released on 2002-06 with total page 122 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report was prepared by the Office of Technology Assessment of the United States Congress to review the health effects of high-voltage transmission lines. For about two decades, there has been some concern about the health effects of electric and magnetic fields produced by transmission lines. Recent studies have heightened this concern. Health effects research is still preliminary and inconclusive, but a growing number of studies suggest that under certain circumstances even relatively weak electric and magnetic fields can produce biologic changes.This report discusses the present state of knowledge on the health effects of low-frequency electric and magnetic fields and describes current U. S. funding levels and research programs. Also, the report provides information on regulatory activity, including existing and proposed field exposure standards.

Download or read book Research on Power Frequency Fields Completed Under the Energy Policy Act of 1992 written by National Research Council and published by National Academies Press. This book was released on 1999-07-07 with total page 111 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the 1970s, concerns about health hazards associated with electric and magnetic fields from power lines and from workplace, school, and household use of electricity have led to many studies and continued controversy about whether adverse health effects occur. In the Energy Policy Act of 1992 (Public Law 102-486), Congress authorized a focused national research program to study the possible health effects of exposure to low-intensity, 60-hertz electric and magnetic fields. In response to this legislation and at the request of the Department of Energy (DOE), the National Research Council established a committee under the Board on Radiation Effects Research (BRER) in the Commission on Life Sciences (CLS) to aid in its review of the power-frequency magnetic field research activities completed under the Electric and Magnetic Fields Research and Public Information Dissemination (EMF-RAPID) program that was authorized by the Energy Policy Act. The Research Council's Committee to Review the Research Activities Completed Under the Energy Policy Act of 1992 (EPACT) was asked to review the EMF-RAPID program implemented by DOE and the National Institute of Environmental Health Sciences (NIEHS), and research strategies suggested by other federal and nonfederal groups.

Download or read book Biological and Health Effects from Exposure to Power line Frequency Electromagnetic Fields written by Hiraku Takebe and published by IOS Press. This book was released on 2001 with total page 568 pages. Available in PDF, EPUB and Kindle. Book excerpt: The possible health effects of electro-magnetic (EMF) from high-voltage electric power lines have been discussed sine the 1970s. The concern was triggered by epidemilogical studies in the United States and Europe that suggested a slightly increased incidence of leukaemia's and brain tumours occured among those living and working near high-voltage power lines. Although studies can indicate an associate between factor and effect, the studies themselves cannot confirm a cause-effect relationship. Whether EMF is producing these ill effects must be confirmed by experimental studies.

Download or read book Frequency Standards written by Fritz Riehle and published by John Wiley & Sons. This book was released on 2006-03-06 with total page 540 pages. Available in PDF, EPUB and Kindle. Book excerpt: Of all measurement units, frequency is the one that may be determined with the highest degree of accuracy. It equally allows precise measurements of other physical and technical quantities, whenever they can be measured in terms of frequency. This volume covers the central methods and techniques relevant for frequency standards developed in physics, electronics, quantum electronics, and statistics. After a review of the basic principles, the book looks at the realisation of commonly used components. It then continues with the description and characterisation of important frequency standards from atomic clocks, to frequency stabilised lasers. The whole is rounded of with a discussion of topical applications in engineering, telecommunications, and metrology.

Download or read book The Use of Ferrites at Microwave Frequencies written by L. Thourel and published by Elsevier. This book was released on 2016-10-27 with total page 115 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Use of Ferrites at Microwave Frequencies describes the applications of ferrites at microwave frequencies and the apparatus involved. Topics covered range from the properties of ferrites to gyromagnetic and non-reciprocal effects, ferrite isolators, circulators, and modulators. The use of ferrites in variable frequency filter cavities is also discussed. Mathematical explanations are reduced to the strict minimum and only the results of calculations are indicated. This book consists of seven chapters and opens with a review of the theory of magnetism, touching on subjects such as the BOHR magneton, diamagnetism and paramagnetism, ferromagnetism and antiferromagnetism, ferrimagnetism, and demagnetizing. The next chapter deals with the elementary theory of gyromagnetic effects and covers the kinetic moment theorem, precession of the spin moment, gyromagnetic resonance, complex permeability, and gyromagnetic effects in the atom. The reader is then introduced to ferrites and their properties; non-reciprocal effects and their applications; and ferrite isolators, circulators, and modulators. The final chapter describes the use of ferrites in the design of cavities whose resonant frequency is controlled by a magnetic field or filters with variable characteristics. This monograph is written primarily for microwave and electronics engineers.

Download or read book Very High Frequency VHF ESR EPR written by Oleg Grinberg and published by Springer Science & Business Media. This book was released on 2004-06-29 with total page 604 pages. Available in PDF, EPUB and Kindle. Book excerpt: The field of Very High Frequency EPR (VHF EPR) or sometimes called Very High Field EPR (conveniently, also abbreviated as VHF EPR) has blossomed during the past decade, especially after the original pioneering work of Ya. S. Lebedev and his group at the Institute of Chemical Physics, Russian Academy of Sciences in Moscow. Although Lebedev suffered heavily under the economic constraints of the communist Soviet Union and then succumbed to cancer at the peak of his scientific career, his groundbreaking work from the 1970's is still considered today to be the 'gold standard' by researchers practicing EPR at high magnetic fields. A stimulus for the production of this book is the legacy of Yakov Levedev in his students now residing in academic positions in the US and elsewhere. The aim of this book is to highlight the state of this growing field. This is an attempt to cover the full scope of VHF EPR in a single volume. The idea for this volume came to the editors at the 2001 Rocky Mountain Analytical Conference during the 24th International EPR Symposium chaired by Sandra and Gareth Eaton. VHF EPR was presented as an independent research field at a workshop organized by LC BruneI and supported by the National High Magnetic Field Laboratory, a National Science Foundation funded facility at Florida State University.
