The Earth’s Electric Field provides you with an integrated and comprehensive picture of the generation of the terrestrial electric fields, their dynamics and how they couple/propagate through the medium. The Earth’s Electric Field provides basic principles of terrestrial electric field related topics, but also a critical summary of electric field related observations and their significance to the various related phenomena in the atmosphere. For the first time, Kelley brings together information on this topic in a coherent way, making it easy to gain a broad overview of the critical processes in an efficient way. If you conduct research in atmospheric science, physics, atmospheric chemistry, space plasma physics, and solar terrestrial physics, you will find this book to be essential reading. The only book on the physics of terrestrial electric fields and their generation mechanisms, propagation and dynamics–making it essential reading for scientists conducting research in upper atmospheric, ionospheric, magnetospheric and space weather Covers the processes related to electric field generation and electric field coupling in the upper atmosphere along with providing new insights about electric fields generated by sources from sun to mud Focuses on real-world implications—covering topics such as space weather, earthquakes, the effect on power grids, and the effect on GPS and communication devices

Non-Chemical Weed Control is the first book to present an overview of plant crop protection against non-food plants using non-chemical means. Plants growing wild—particularly unwanted plants found in cultivated ground to the exclusion of the desired crop—have been treated with herbicides and chemical treatments in the past. As concern over environmental, food and consumer safety increases, research has turned to alternatives, including the use of cover crops, thermal treatments and biotechnology to reduce and eliminate unwanted plants. This book provides insight into existing and emerging alternative crop protection methods and includes lessons learned from past methodologies. As crop production resources decline while consumer concerns over safety increase, the effective control of weeds is imperative to insure the maximum possible levels of soil, sunlight and nutrients reach the crop plants. Allows reader to identify the most appropriate solution based on their individual use or case Provides researchers, students and growers with current concepts regarding the use of modern, environment-friendly weed control techniques Presents methods of weed management—an important part of integrated weed management in the future Exploits the knowledge gained from past sustainable weed management efforts

Hazardous energy present in systems, machines, and equipment has injured, maimed, and killed many workers. One serious injury can stop the growth of your business in its tracks. Management of Hazardous Energy: Deactivation, De-Energization, Isolation, and Lockout provides the practical tools needed to assess hazardous energy in equipment, machines, and systems, and covers how to manage hazardous energy through elimination or control in order to ensure worker safety and regulatory compliance. Written in plain English with a minimum of jargon, this book provides safety professionals with the knowledge they need to interact with specialists, designers, and engineers to ensure that appropriate and necessary protocols and safety practices and tools are put into place for assessing the dangers and steps taken to eliminate or control exposure to hazardous energy when needed. Approaching the subject from the bottom up, the author starts at the workplace level, to ensure that the right actions happen for the right reasons. The book explains a protocol for describing the flow of energy, including transformation and/or storage; for capturing the logic of decisions about control, including failure analysis and contingency planning; and ultimately for creating procedures that are technically sound and defensible. Creating simple procedures for ensuring worker safety and regulatory compliance, the book offers US and international strategies for hazardous energy management and contains examples to illustrate the application of concepts to specific areas.

Extreme Events in Geospace: Origins, Predictability, and Consequences helps deepen the understanding, description, and forecasting of the complex and inter-related phenomena of extreme space weather events. Composed of chapters written by representatives from many different institutions and fields of space research, the book offers discussions ranging from definitions and historical knowledge to operational issues and methods of analysis. Given that extremes in ionizing radiation, ionospheric irregularities, and geomagnetically induced currents may have the potential to disrupt our technologies or pose danger to human health, it is increasingly important to synthesize the information available on not only those consequences but also the origins and predictability of such events. Extreme Events in Geospace: Origins, Predictability, and Consequences is a valuable source for providing the latest research for geophysicists and space weather scientists, as well as industries impacted by space weather events, including GNSS satellites and radio communication, power grids, aviation, and human spaceflight. The list of first/second authors includes M. Hapgood, N. Gopalswamy, K.D. Leka, G. Barnes, Yu. Yermolaev, P. Riley, S. Sharma, G. Lakhina, B. Tsurutani, C. Ngwira, A. Pulkkinen, J. Love, P.

Airapetian, D. Boteler, M. MacAlester, S. Worman, D. Neudegg, and M. Ishii. Helps to define extremes in space weather and describes existing methods of analysis Discusses current scientific understanding of these events and outlines future challenges Considers the ways in which space weather may affect daily life Demonstrates deep connections between astrophysics, heliophysics, and space weather applications, including a discussion of extreme space weather events from the past Examines national and space policy issues concerning space weather in Australia, Canada, Japan, the United Kingdom, and the United States

This book provides a review of Azerbaijan’s water reserves and main economic deposits (both hydrocarbon and hard) and describes the integrated application of geophysical methods (land, airborne, shipborne and satellite) for studying near-surface and environmental features and regional tectonic-geophysical zonation as well as the study of deep structures in the search for hydrocarbon and hard (polymetallic, copper, gold-bearing, iron-ore, magnetite, etc.) deposits. It particularly focuses on the geophysical examination of seismic activity in the region related to the interaction of the Afro-Arabian and Eurasian lithospheric plates. It is aimed at scientists, engineers and students interested in the commercial potential of Azerbaijan’s deposits and the application of different geophysical methodologies (gravity, magnetic, seismic, thermal, electric, electromagnetic, etc.) for analyzing mud volcanism, identifying subsurface structures (including the analysis of hydrogeological problems, the examination of past climates and archaeological inspection) revealing the deep tectono-structural peculiarities of the region under study, mining and oil & gas geophysics, development of 3D physical-geological models and advanced seismological prognosis.
