Applied Natural Science: Environmental Issues and Global Perspectives provides the reader with a complete insight into the natural-scientific pattern of the world, covering the most important historical stages of the development of various areas of science, methods of natural-scientific research, general scientific and philosophical concepts, and the fundamental laws of nature. The book analyzes the main scientific trends and developments of modern natural science and also discusses important aspects of environmental protection.Topics include:The problem of "the two cultures": the mathematization of natural sciences and the informatization of societyThe non-linear nature of the processes occurring in nature and societyApplication of the second law of thermodynamics to describe the development of biological systemsGlobal problems of the biosphereTheory and practice of stable organic paramagnetic materialsPolymers and the natural environmentKey features include:An interdisciplinary approach in considering scientific and technical problemsA discussion of general scientific trends in modern natural science, including globalization challenges in nature and society, the organic chemistry of stable paramagnetic materials, the fundamentals of the environmental chemistry of polymeric materials, etc.A justification of applying classical (non-equilibrium) thermodynamics to studying the behavior of open (including biological) systemsOf particular importance in the book is the discussion of some problems associated with the place of man in the biosphere, issues of the globalization of science and technology, new ideas about the universe, and the concept of universal evolutionism. At the same time, the book discusses more specific issues related to solving major global and regional environmental problems (particularities of organic paramagnetic materials, the influence of polymers on the man and environment, etc). All this leads to the fundamental conclusion of the unity of animate and inanimate nature, as well as improvement of the process of cognition of the real world, which consists in objective and natural changing of world views.The book is intended for professors, teachers, and students of classical and technological universities who are interested in the development of the foundations of modern natural sciences, as well as for professionals working in the field of chemical physics and applied ecology.

This book presents the physical characteristics and possible device applications of europium monoxide as well as materials based on it. It reveals the suitability of this material for device applications in super- and semiconductor spin electronics. Ferromagnetic semiconductors like europium monoxide have contributed to a fascinating research field in condensed matter physics. In the book are presented the electronic and magnetic properties and thermal and resonance parameters of this material, its peculiarities in external fields as a function of non-stoichiometry, doping level, both in single-crystal and thin-film states. Particular attention is paid to the possibility to use this monoxide or its solid solutions (composites) unconventionally for creating spin electronics structures which work at room temperature conditions. This book appeals to researchers, graduate students and professionals engaged in the development of semiconductor spin electronics and computer devices,technologists and theoretical physicists. It is important for the calculation, development and creation of spin memory devices for a quantum computer.

This book is devoted to one of the main problems of modern electrical power engineering—power transformer diagnostics. The first three chapters discuss the fundamentals: The first chapter presents the physical reasons for power transformers’ failures and the technical and economic consequences of disruption of the normal operation. The second chapter reviews the standard technologies for monitoring the state of the high-voltage transformers. The third chapter tells about monitoring the condition of transformer windings based on the pulse method. The fourth chapter presents the technologies for transformer windings condition controlled by means of nanosecond pulses. The stages of improving the pulsed method based on a short probing pulse of the nanosecond range, the results of experiments on identifying the radial and axial displacements of the winding, studies of the effect of the duration and shape of the probing pulse on the sensitivity of the diagnostic procedure, and the stages of developing a mathematical as well as physical model of a power transformer are consistently presented.

This textbook covers in detail the problem of improving the reliability and service life of high-voltage equipment in electric power systems, mainly through testing, monitoring, and diagnostics, which support the timely repair or replacement of equipment. The main focus is on high-voltage power and instrument transformers, switching devices, powerful rotating electric machines, capacitors, bushings, and power cables.The design, purpose, and principle of operation for each respective type of equipment, as well as adverse factors that can lead to defects (primarily in insulation) – and, as a result, to accelerated aging (wear) and failure – are considered.In turn, the scientific and technological foundations and practical application of testing, monitoring, and diagnostics to determine the technical condition of equipment are described. Considerable attention is paid to new and promising methods for testing under voltage (without interrupting operation) – such as pulsed flaw detection and dielectric spectroscopy. In addition, the authors propose a number of helpful physical concepts and technical solutions.The book stands out in terms of the breadth and depth of the consideration of the problem, which reflects recent trends and concepts for the development of the electric power industry, and its convincing demonstration of the capabilities of traditional and advanced methods in relation to the main equipment used in electric power systems.The textbook is intended for undergraduate and graduate students in the field of high-voltage technologies for electric power systems. It also benefits engineering personnel working with electric power systems and in the electrical industry.

The book is devoted to the description of the fundamentals in the area of magnetic resonance. The book covers two domains: radiospectroscopy and quantum radioelectronics. Radiospectroscopy comprises nuclear magnetic resonance , electron paramagnetic resonance, nuclear quadrupolar resonance, and some other phenomena. The radiospectroscopic methods are widely used for obtaining the information on internal (nano, micro and macro) structure of objects. Quantum radioelectronics, which was developed on the basis of radiospectroscopic methods, deals with processes in quantum amplifiers, generators and magnetometers. We do not know analogues of the book presented. The book implies a few levels of the general consideration of phenomena, that can be useful for different groups of readers (students, PhD students, scientists from other scientific branches: physics, chemistry, physical chemistry, biochemistry, biology and medicine).

Aleksej Salnikov rodilsja v 1978 godu v Tartu. Publikovalsja v almanakhe "Vavilon", zhurnalakh "Vozdukh", "Ural", "Volga". Avtor trekh poeticheskikh sbornikov. Laureat premii "LiteratuRRentgen" (2005), finalist "Bolshoj knigi" i "NOS". Zhivet v Ekaterinburge. "Pishet Salnikov kak, pozhaluj, nikto drugoj segodnja, a imenno — svezho, kak pervyj den tvorenija. Na kazhdom shagu on vybivaet u chitatelja pochvu iz-pod nog, rasshatyvaet natrenirovannyj mnogoletnim chteniem “normalnykh” knig vestibuljarnyj apparat. Vse sluchajnye znaki, vstrechennye grippujuschimi Petrovymi v ikh boleznennom polubredu, sobirajutsja v strojnuju konstruktsiju bez edinoj lishnej detali. Iz vsekh schelej nachinaet sochitsja takaja razveselaja khton i infernalnaja zhut, chto Mamleev s Gorchevym druzhno puskajutsja v pljas, a Gogol s Bulgakovym aplodirujut. Porazitelnyj, edinstvennyj v svoem rode jazyk, zazemlennyj i osjazaemyj materialnyj mir i po-nastojaschemu volshebnaja mertsajuschaja neodnoznachnost (to li vse proiskhodjaschee v romane — grippoznye galljutsinatsii trekh Petrovykh, to li i pravda obnazhilas na mgnovenie koldovskaja iznanka mira) — kak ni posmotri, vydajuschijsja tekst i nastojaschij chitatelskij prazdnik".
