With its many beautiful colour pictures, this book gives fascinating insights into the unusual forms and behaviour of matter under extremely high pressures and temperatures. These extreme states are generated, among other things, by strong shock, detonation and electric explosion waves, dense laser beams, electron and ion beams, hypersonic entry of spacecraft into dense atmospheres of planets and in many other situations characterized by extremely high pressures and temperatures. Written by one of the world's foremost experts on the topic, this book will inform and fascinate all scientists dealing with materials properties and physics and also serve as an excellent introduction to plasma-, shock-wave and high-energy-density physics for students and newcomers seeking an overview. This second edition is thoroughly revised and expanded, in particular with new material on high energy-density physics, nuclear explosions and other nuclear transformation processes.
Principles of Bioenergetics summarizes one of the quickly growing branches of modern biochemistry. Bioenergetics concerns energy transductions occurring in living systems and this book pays special attention to molecular mechanisms of these processes. The main subject of the book is the "energy coupling membrane" which refers to inner membranes of intracellular organelles, for example, mitochondria and chloroplasts. Cellular cytoplasmic membranes where respiratory and photosynthetic energy transducers, as well as ion-transporting ATP-synthases (ATPases) are also part of this membrane. Significant attention is paid to the alternative function of mitochondria as generators of reactive oxygen species (ROS) that mediate programmed death of cells (apoptosis and necrosis) and organisms (phenoptosis). The latter process is considered as a key mechanism of aging which may be suppressed by mitochondria-targeted antioxidants.
This monograph narrates not only the theoretical aspects and experimental data, but also outlines new approaches to the prevention of aging and age-related pathology, thus addressing a wide readership of gerontologists, geneticists, molecular biologists, biochemists, and pharmacologists alike.
This book focuses on the non-traditional branches of physics and mechanics of shock waves that have arisen recently in connection with the intensive study of these waves in a wide variety of phenomena - from nuclear matter to clusters of galaxies. The book is devoted to the various physical phenomena and properties of intense shock waves. The author addresses methods of generation, diagnostics, as well as theoretical methods for describing shock waves at extremely high pressures and temperatures in laboratory and quasi-laboratory conditions. The state of materials with high energy density generated by shock wave compression is discussed. In addition, the book aims to systematize, generalize, and describe from a universal viewpoint the extensive theoretical and experimental material on the physics of high energy densities - the physics and mechanics of intense shock waves. The book is based on lectures delivered by the author at the Moscow Institute of Physics and Technology, the Higher School of Physics of Rosatom State Nuclear Energy Corporation, as well as overviews presented at many scientific conferences and symposia. It is useful to a wide range of researchers in natural sciences, giving them access to original works and allowing them to navigate the fascinating problems of the modern science of intense shock waves.
This book presents results of the combined use of microwave remote sensing, optical tools, and ecoinformatics methods under solution-applied tasks at both regional and global scales. Ecoinformatics methods are used to assess links between global climate change and the level of ocean pollution, with specific focus on the Arctic Ocean, the Sea of Okhotsk, and the South-China Sea. The theoretical and applied aspects of instrumental tools are considered in this book as a basis for the monitoring of water quality in various watersheds, with particular attention to microwave remote sensing monitoring data to determine the ecotoxicological status of hydro-ecosystems affected by climate change. The book develops new information technologies that provide solutions for hydrochemical tasks using algorithms and models based on computer technologies for big data processing. This will help to synthesize effective computer-based systems for the solution of problems arising due to anthropogenic impacts on hydrological processes and objects at various spatial scales. This book is intended for specialists in the fields of environmental monitoring, climate change, human-nature interactions, and geopolitics. The book will be useful for undergraduate and postgraduate students studying these fields of science as well.
The book is devoted to the physics of plasma at high density, which has been compressed so strongly that the effects of interparticle interactions and non-ideality govern its behavior. Interest in this non-traditional plasma has been generated in recent years when states of matter with high concentration of energy became accessible experimentally as the basis of modern technologies and facilities. The greatest part of the matter in the Universe is in this exotic state. In this book,the methods of generation and diagnostics of strongly coupled plasmas are presented, along with the main theoretical methods and experimental results on thermodynamical, kinetic and optical properties. Particular attention is given to fast developing modern directions of strongly coupled plasmaphysics such as metallization of dielectrics and dielectrization of metals, non-neutral plasmas, dusty plasmas and their crystallization. The book is written for physicists and astrophysicists, engineers, and material scientists.
The quantum theory of magnetism is a well-developed part of contemporary solid-state physics. The basic concepts of this theory can be used to describe such important effects as ferromagnetic ordering oflocalized magnetic moments in crystals and ferromagnetism of metals produced by essentially delocalized electrons, as well as various types of mutual orientation of atomic magnetic moments in solids possessing different crystal lattices and compositions. In recent years,the spin-fluctuational approach has been developed, which can overcome some contradictions between "localized" and "itinerant" models in the quantum mechanics of magnetic crystals. These are only some of the principal achievements of quantum magnetic theory. Almost all of the known magnetic properties of solids can be qualitat ively explained on the basis of its concepts. Further developments should open up the possibility of reliable quantitative description of magnetic properties of solids. Unfortunately, such calculations based on model concepts appear to be very complicated and, quite often, not definite enough. The rather small number of parameters of qualitative models are usually not able to take into account the very different types of magnetic interactions that appear in crystals. Further development of magnetic theory requires quantitative information on electronic wave function in the crystal considered. This can be proved by electronic band structure and cluster calculations. In many cases the latter can be a starting point for quantitative calculations of parameters used in magnetic theory.
Polyamic Acids and Polyimides surveys significant developments in basic research in the chemistry and physics of polyamic acids and polyimides over the last several years. Traditional and new topics are discussed, including catalytical imidization, chemical reactions at thermal treatment, quantum-chemical study of synthesis and structure, properties of isolated molecules, and supermolecular and crystalline structures. The book will be an excellent reference for researchers, practitioners, and graduate students working with polyimides and related heat-resistant polymers and materials.
The monograph is devoted to the description of the kinetics of spontaneous boiling of superheated liquefied gases and their solutions. Experimental results are given on the temperature of accessible superheating, the limits of tensile strength of liquids due to processes of cavitation and the rates of nucleation of classical and quantum liquids. The kinetics of evolution of the gas phase is studied in detail for solutions of cryogenic liquids and gas-saturated fluids. The properties of the critical clusters (bubbles of critical sizes) of the newly evolving gas phase are analyzed for initial states near the equilibrium coexistence curves of liquid and gas, for states near the limits of accessible superheating and for initial states near the respective spinodal curves. Finally, processes of explosive boiling of cryogenic liquids are considered occurring as the result of outflow processes and intensive interactions with high-temperature liquid samples.
Shlapentokh undertakes a dispassionate analysis of the ordinary functioning of the Soviet system from Stalin's death through the Soviet collapse and Russia's first post-communist decade. Without overlooking its repressive character, he treats the USSR as a "normal" system that employed both socialist and nationalist ideologies for the purposes of technological and military modernization, preservation of empire, and expansion of its geopolitical power. Foregoing the projection of Western norms and assumptions, he seeks to achieve a clearer understanding of a civilization that has perplexed its critics and its champions alike.

Branching processes are stochastic processes which represent the reproduction of particles, such as individuals within a population, and thereby model demographic stochasticity. In branching processes in random environment (BPREs), additional environmental stochasticity is incorporated, meaning that the conditions of reproduction may vary in a random fashion from one generation to the next. This book offers an introduction to the basics of BPREs and then presents the cases of critical and subcritical processes in detail, the latter dividing into weakly, intermediate, and strongly subcritical regimes.

This book gives new insight to the study of the global environmental changes using the ecoinformatics and microwave remote sensing tools together with the adaptive-evolutionary technology of geoinformation monitoring. The main advantage of this book consists in the accumulation of the interdisciplinary scientific knowledge for the parameterization of the global biogeochemical cycles and other environmental processes in the context of globalization and sustainable development. In this regard, the crucial global problems of the dynamics of the climate-nature-society system have been considered and the key problems of ensuring its sustainable development have been addressed. An analysis of the present trend in changing ecological systems has been discussed, including different types of forest ecosystems and ocean aquatories. The emphasis has been given to the accomplishment of the global geoinformation monitoring, which could provide a reliable control of the environmental processes development with reliable prognostic estimates of the consequences of human activities. A new approach to the numerical modelling of the climate-nature-society system has been presented and demonstrative results have been given about the modelling of the dynamics of this system‟s characteristics, in cases of realization of some scenarios of the anthropogenic impacts to the biogeochemical cycles, the land ecosystems and oceans. Methods and algorithms for the big data manipulation and processing in the remote sensing environmental monitoring systems have been described.
The evolution of systems in random media is a broad and fruitful field for the applica tions of different mathematical methods and theories. This evolution can be character ized by a semigroup property. In the abstract form, this property is given by a semigroup of operators in a normed vector (Banach) space. In the practically boundless variety of mathematical models of the evolutionary systems, we have chosen the semi-Markov ran dom evolutions as an object of our consideration. The definition of the evolutions of this type is based on rather simple initial assumptions. The random medium is described by the Markov renewal processes or by the semi Markov processes. The local characteristics of the system depend on the state of the ran dom medium. At the same time, the evolution of the system does not affect the medium. Hence, the semi-Markov random evolutions are described by two processes, namely, by the switching Markov renewal process, which describes the changes of the state of the external random medium, and by the switched process, i.e., by the semigroup of oper ators describing the evolution of the system in the semi-Markov random medium.
The inside story of the political collpase of the Soviet Union is far better understood than the course of economic and social disintegration. In order to capture the story, the editors compiled a list of questions which they addressed to former top Soviet officials and economic and other policy advisors (both Soviet and foreign) who were privy not only to data on the functioning of the Soviet economy but also to the internal policy debate during the 1980s. This volume assembles the Informants' analyses of key issues and the turning points, and weaves them into a compelling history of systemic collapse. Among the topics investigated are: economic policies in the 1980s; the standard of living: the reliability of Soviet statistics; Gosplan's projections for the economy to the year 2000; was the arms race starving the civilian economy? the role of ideology in supporting the functioning of an economic system; the party's participating in economic management; the influence of foreign advisors; the struggle over a transition program; the functioning and collapse of the supply system, the CMEA, and the foreign trade system.
Basing his work on research in police, procuracy, KGB and party archives, Vladimir A. Kozlov traces the historical context and sequences of events leading up to mass protest in Russia. He explores the demographic and psychological dynamics of the situation and the reactions of the authorities.
In 1946 at the beginning of the cold war, the USSR government organized a special Institute on Infrared Technique and Electron Optics, later renamed the Federal Scientific Center ""Orion."" On the occasion of the Orion Center's 60th anniversary, this volume chronicles the development and achievements of IR techniques, photoelectronics, and other defense technologies in the former USSR and Russia. It contains nearly 300 photographs of researchers and IR devices and systems, most published here for the first time.
The “altogether astonishing” true story of a black American finding fame and fortune in Moscow and Constantinople at the turn of the 20th century (Booklist, starred review). The Black Russian tells the true story of Frederick Bruce Thomas, a man born in 1872 to former slaves who became prosperous farmers in Mississippi. But when his father was murdered, Frederick left the South to work as a waiter in Chicago and Brooklyn. Seeking greater freedom, he traveled to London, then crisscrossed Europe, and—in a highly unusual choice for a black American at the time—went to Russia. Because he found no color line there, Frederick settled in Moscow, becoming a rich and famous owner of variety theaters and restaurants. When the Bolshevik Revolution ruined him, he barely escaped to Constantinople, where he made another fortune by opening celebrated nightclubs as the “Sultan of Jazz.” Though Frederick reached extraordinary heights, the long arm of American racism, the xenophobia of the new Turkish Republic, and Frederick’s own extravagance brought his life to a sad close, landing him in debtor’s prison, where he died a forgotten man in 1928. “In his assiduously researched, prodigiously descriptive, fluently analytical” narrative (Booklist, starred review), Alexandrov delivers “a tale . . . so colourful and improbable that it reads more like a novel than a work of historical biography.” (The Literary Review). “[An] extraordinary story . . . [interpreted] with great sensitivity.” —The New York Review of Books
This book presents a summary of the topic of supercooling during crystallization in condensed films. While recent findings are mainly published in English, the foundational classical results were originally published in Russian, with limited accessibility to general readers. The present work is based on a 2019 Ukrainian monograph, "Temperature Stability of the Supercooled Liquid Phase in Condensed Films," which has been extensively revised and expanded. The book includes a detailed analysis of the thermodynamics of supercooled fluids, with updated and expanded sections. Additionally, new results on the supercooling of indium-lead (In-Pb) alloys in contact with amorphous molybdenum and fusible metals in contact with nanocrystalline layers are presented. These layers occupy a middle ground between amorphous (carbon, molybdenum, as-deposited germanium films) and polycrystalline (copper, silver, aluminum) substrates. The book gives particular attention to the peculiarities of contracted geometry conditions, which are natural for multilayered structures and can occur through fusible component segregation at grain boundaries. The analysis of new data has prompted a rethinking of the role of the more refractory layer's microstructure on the crystallization processes of metastable melts. The book includes a thorough discussion of these findings, highlighting the crucial role of the microstructure in the crystallization process. This book is a valuable resource for researchers and students interested in crystallization in thin-film metallic systems. This comprehensive study provides a detailed and authoritative analysis of the thermodynamics of supercooled fluids, and the impact of microstructure on the crystallization processes of metastable melts, making it an essential addition to any academic library.
In this book, Vladimir Gel’man considers bad governance as a distinctive politico-economic order that is based on a set of formal and informal rules, norms, and practices quite different from those of good governance. Some countries are governed badly intentionally because the political leaders of these countries establish and maintain rules, norms, and practices that serve their own self-interests. Gel’man considers bad governance as a primarily agency-driven rather than structure-induced phenomenon. He addresses the issue of causes and mechanisms of bad governance in Russia and beyond from a different scholarly optics, which is based on a more general rationale of state-building, political regime dynamics, and policy-making. He argues that although these days, bad governance is almost universally perceived as an anomaly, at least in developed countries, in fact human history is largely a history of ineffective and corrupt governments, while the rule of law and decent state regulatory quality are relatively recent matters of modern history, when they emerged as side effects of state-building. Indeed, the picture is quite the opposite: bad governance is the norm, while good governance is an exception. The problem is that most rulers, especially if their time horizons are short and the external constraints on their behavior are not especially binding, tend to govern their domains in a predatory way because of the prevalence of short-term over long-term incentives. Contemporary Russia may be considered as a prime example of this phenomenon. Using an analysis of case studies of political and policy changes in Russia after the Soviet collapse, Gel’man discusses the logic of building and maintaining the politico-economic order of bad governance in Russia and paths of its possible transformation in a theoretical and comparative perspective.
Professor Skripov obtained worldwide recognition with his monograph "Metastable liquids", published in English by Wiley & Sons. Based upon this work and another monograph published only in Russia, this book investigates the behavior of melting line and the properties of the coexisting crystal and liquid phase of simple substances across a wide range of pressures, including metastable states of the coexisting phases. The authors derive new relations for the thermodynamic similarity for liquid-vapour phase transition, as well as describing solid-liquid, liquid-vapor and liquid-liquid phase transitions for binary systems employing the novel methodology of thermodynamic similarity.
In most cases the problems caused by financial globalization are identical in various countries, which is why it is especially important to develop some standard solutions. Nevertheless, it is also doubtless that economic "recipes" for "small" and "big" countries can be different and it would be a mistake to apply only a uniform approach to all of them. The book evaluates an international financial system development potential in the context of "corporate crises" started in the USA and a probable impact on international financial markets and business activities. With the introduction of the Euro, a "new three-pole world currency system" was established. In this connection, two quite sensational forecasts made during the last two years regarding the collapse of the US Dollar are analyzed. These forecasts make a pretty "gloomy picture" of the future of both the US Dollar and the international monetary system. The book draw reader's attention to global exchange rate instability and its implications for Georgia. It is demonstrated that as a small economy, Georgia cannot have any substantial influence on global economic developments; however, if it succeeds to pursue more-or-less reasonable economic policy, it may generate some positive results, or at least minimize negative ones.
This English translation of a work previously published in Russian (Geoarkheologiya i radiouglerodnaya khronologiya kamennogo veka Severo Vostochnoi Azii, St. Petersburg: Nauka, 2010) presents an overview of the Paleolithic archaeology of Northeast Asia, with emphasis on geoarchaeological and radiocarbon-based chronology. Although archaeological investigations above the Arctic Circle began more than two hundred years ago, access to and publication of findings has been difficult. In Geoarchaeology and Radiocarbon Chronology of Stone Age Northeast Asia, veteran researchers Vladimir V. Pitul’ko and Elena Yu. Pavlova have gathered and analyzed the available data to provide comprehensive documentation of human occupation of continental territories far above the Arctic Circle in the late Neopleistocene (also known as the Late Pleistocene era). By using uncalibrated radiocarbon dating, Pitul’ko and Pavlova have been able to establish reliable correlations between the artifacts and phenomena being studied. The increased number of radiocarbon age determinations for these Arctic sites is the most important data to come from the latest studies of Northeast Asia, offering a significant opportunity for re-evaluation of older materials in light of these new findings. The authors include reporting on recent work performed at two of the most important sites in the region: the “mammoth cemetery” site at Berelekh and the Yana Rhinoceros Horn Site.
This book is based on a lecture course to students specializing in the safety of technological processes and production. The author focuses on three main problems in technological risks and safety: elements of reliability theory, the basic notions, models and methods of general risk theory and some aspects of insurance in the context of risk management. Although the material in this book is aimed at those working towards a bachelor's degree in engineering, it may also be of interest to postgraduate students and specialists dealing with problems related to reliability and risks.
In this unprecedented work on the status and role of intellectuals in Soviet political life, a former Soviet sociologist maps out the delicate, often paradoxical, ties between the political regime and the creative thinkers who play a major part in the movement toward modernization. Beginning with Stalin, Vladimir Shlapentokh explores the mutual need and antagonism that have existed between political leaders and intellectuals. What emerges is a fascinating portrayal of the Soviet intellectual network since the 1950s, which touches on such topics as the role of literature and film in political opposition, levels of opposition (open, legal, and private), and the spread of paranoia as fueled by the KGB. Throughout he shows how the intellectual communityusually a cohesive, liberal grouphas fared under Khrushchev's cautious tolerance, Brezhnev's repressions, and now Gorbachev's Glasnost. Shlapentokh maintains, however, that under Glasnost freer speech has revealed a more pronounced divergence between liberal and conservative thinkers, and has allowed for open conservative opposition to the reformatory measures of Gorbachev and the liberals. He argues that one of the strongest checks on reform is the growing presence of Russophilism--a movement supporting Russian nationalism and Stalin's concept of socialism--among the political elite and the masses. Although the role of the liberal intellectuals in the late 1980s was less prominent than it was in the 1960s, Shlapentokh asserts that they remain the major agent of modernization in the Soviet Union, as well as in other socialist countries. Originally published in 1990. The Princeton Legacy Library uses the latest print-on-demand technology to again make available previously out-of-print books from the distinguished backlist of Princeton University Press. These editions preserve the original texts of these important books while presenting them in durable paperback and hardcover editions. The goal of the Princeton Legacy Library is to vastly increase access to the rich scholarly heritage found in the thousands of books published by Princeton University Press since its founding in 1905.
The unique behavior of the "liquid state", together with the richness of phenomena that are observed, render liquids particularly interesting for the scientific community. Note that the most important reactions in chemical and biological systems take place in solutions and liquid-like environments. Additionally, liquids are utilized for numerous industrial applications. It is for these reasons that the understanding of their properties at the molecular level is of foremost interest in many fields of science and engineering. What can be said with certainty is that both the experimental and theoretical studies of the liquid state have a long and rich history, so that one might suppose this to be essentially a solved problem. It should be emphasized, however, that although, for more than a century, the overall scientific effort has led to a considerable progress, our understanding of the properties of the liquid systems is still incomplete and there is still more to be explored. Basic reason for this is the "many body" character of the particle interactions in liquids and the lack of long-range order, which introduce in liquid state theory and existing simulation techniques a number of conceptual and technical problems that require specific approaches. Also, many of the elementary processes that take place in liquids, including molecular translational, rotational and vibrational motions (Trans. -Rot. -Vib. coupling), structural relaxation, energy dissipation and especially chemical changes in reactive systems occur at different and/or extremely short timescales.
This monograph contains original results in the field of mathematical and numerical modeling of mechanical behavior of granular materials and materials with different strengths. It proposes new models helping to define zones of the strain localization. The book shows how to analyze processes of the propagation of elastic and elastic-plastic waves in loosened materials, and constructs models of mixed type, describing the flow of granular materials in the presence of quasi-static deformation zones. In a last part, the book studies a numerical realization of the models on multiprocessor computer systems. The book is intended for scientific researchers, lecturers of universities, post-graduates and senior students, who specialize in the field of the deformable materials mechanics, mathematical modeling and adjacent fields of applied and calculus mathematics.
The politico-economic reforms launched during the late twentieth century in post-Soviet Russia have led to contradictory and ambiguous results. The new economic environment and mode of governance that emerged have been subjected to serious criticism. What were the causes of these developments? Were they unavoidable for Russia due to specific factors grounded in the country’s previous experiences? Or were they an intended result of actions taken by the leaders of the country during the last few decades? The authors of this book share neither a deterministic approach, which implies that Russia is bound to fail because of the nature of its economic and political evolution, nor a voluntarist approach, which implies that these failures were caused only by the incompetence and/or malicious intentions of its leaders. Instead, this study offers a different framework for the analysis of political and economic developments in present-day Russia. It is based on four ‘i’s—ideas, interests, institutions, and illusions.
This book provides recent results on the stochastic approximation of systems by weak convergence techniques. General and particular schemes of proofs for average, diffusion, and Poisson approximations of stochastic systems are presented, allowing one to simplify complex systems and obtain numerically tractable models.The systems discussed in the book include stochastic additive functionals, dynamical systems, stochastic integral functionals, increment processes and impulsive processes. All these systems are switched by Markov and semi-Markov processes whose phase space is considered in asymptotic split and merging schemes. Most of the results from semi-Markov processes are new and presented for the first time in this book.
In this monograph stochastic models of systems analysis are discussed. It covers many aspects and different stages from the construction of mathematical models of real systems, through mathematical analysis of models based on simplification methods, to the interpretation of real stochastic systems. The stochastic models described here share the property that their evolutionary aspects develop under the influence of random factors. It has been assumed that the evolution takes place in a random medium, i.e. unilateral interaction between the system and the medium. As only Markovian models of random medium are considered in this book, the stochastic models described here are determined by two processes, a switching process describing the evolution of the systems and a switching process describing the changes of the random medium. Audience: This book will be of interest to postgraduate students and researchers whose work involves probability theory, stochastic processes, mathematical systems theory, ordinary differential equations, operator theory, or mathematical modelling and industrial mathematics.
An aviation historian explores Russian airborne assault innovations in the decade before WWII using paratrooper memoirs and archival research. Through the 1930s, the USSR was pioneering new developments and technologies in airborne assault. The Red Army was conducting mass airborne assault exercises—dropping paratroopers, tanks, and guns from the skies—when no other nation on Earth even had airborne assault troops. In Red Assault, the Russian aviation historian Vladimir Kotelnikov explores these pioneering achievements. He describes the armament, equipment, and military hardware developed for airborne troops, as well as fantastical projects that reflect the unrestrained imagination of the Soviet military’s aviation designers. Kotelnikov offers a detailed account of the aircraft designed for airborne troops, while also describing troop drop exercises and real operations leading up to 1941. Kotelnikov’s research is drawn from government archives and museum collections, as well as the memoirs of pioneer military paratroopers in the USSR, some of which have never been published before.
Recently a new sphere in materials science· has formed which subject is structure and properties of electret materials used in engineering, medicine, biotechnology and other branches. It is characterized by specific methods of experimental investigations based on recording charge transfer, polarization and depolarization of dielectrics and involves original techniques and physico-mathematical aids where notions that exist at the interface of several natural and technical sciences are concentrated. It embraces a vast area of applications mainly in engineering, instrument making, electronics, medical technique, biotechnology, and etc., has a specialized technological base for electric polarization of dielectrics composed of uncommon technological methods, equipment and instrumentation. Apparently, future fundamental investigations in the domain of electret materials science are to be developed at the interface of computer of dielectrics. Elaboration of a simulation, physics and physical chemistry model for electric polarization of solid media with uneven charge density distribution, complicated by surface phenomena, outer electromagnetic, heat, chemical and other effects, presents a grave methodological problem. The simulation of structures in which polarization follows diffusion mechanism of chemically active molecules or their fragments, and the development of calculation methods for polarized charge relaxation and regularities of dielectric nonlinear properties, are the most urgent objectives of current research. Success in bioelectret effect studies is anticipated to result in profound widening of natural science knowledge.
