This book presents recent theoretical and experimental results of localized optical modes and low-threshold lasing in spiral photonic media. Efficient applications of localized modes for low-threshold lasing at the frequencies of localized modes are a central topic of the book's new chapters. Attention is paid to the analytical approach to the problem. The book focuses on one of the most extensively studied media in this field, cholesteric liquid crystals. The chosen model, in the absence of dielectric interfaces, allows to remove the problem of polarization mixing at surfaces, layers and defect structures. It allows to reduce the corresponding equations to the equations for light of diffracting polarization only. The problem concentrates then on the edge and defect optical modes. The possibility to reduce the lasing threshold due to an anomalously strong absorption effect is presented theoretically for distributed feedback lasing. It is shown that a minimum of the threshold-pumping wave intensity can be reached for the pumping wave frequency coinciding with the localized mode frequency (what can be reached for a pumping wave propagating at a certain angle to the helical axes). Analytic expressions for transmission and reflection coefficients are presented. In the present second edition, experimental observations of theoretically revealed phenomena in spiral photonic media are discussed. The main results obtained for spiral media are qualitatively valid for photonic crystals of any nature and therefore may be applied as a guide to investigations of other photonic crystals where the corresponding theory is more complicated and demands a numerical approach. It is demonstrated that many optical phenomena occurring at the frequencies of localized modes reveal unusual properties which can be used for efficient applications of the corresponding phenomena, efficient frequency conversion and low threshold lasing, e.g. For the convenience of the reader, an introduction is given to conventional linear and nonlinear optics of structured periodic media. This book is valuable to researchers, postgraduate, and graduate students active in theoretical and experimental physics in the field of interaction of radiation with condensed matter.
Thermal-hydraulic instability can potentially impair thermal reliability of reactor cores or other power equipment components. Thus it is important to address stability issues in power equipment associated with thermal and nuclear installations, particularly in thermal nuclear power plants, chemical and petroleum industries, space technology, and radio, electronic, and computer cooling systems. Coolant Flow Instabilities in Power Equipment synthesizes results from instability investigations around the world, presenting an analysis and generalization of the published technical literature. The authors include individual examples on flow stability in various types of equipment, including boilers, reactors, steam generators, condensers, heat exchangers, turbines, pumps, deaerators, bubblers, and pipelines. They also present information that has not been widely available until recently, such as thermal-acoustic instability, flow instability with supercritical parameters, and single-phase coolant flow static instability. The material described in this book is derived from vast amounts of experimental data from thermal-physical test facilities and full-scale installations. It is presented in a manner accessible to readers without advanced mathematical backgrounds. Particular attention has been paid to oscillatory (low-frequency and thermal-acoustic) and static thermal-hydraulic coolant flow instability. In addition, the physical mechanism of instability has been considered in detail. This book provides knowledge of the various types of flow instability, the equipment where this instability can manifest, and the ensuing consequences, as well as makes recommendations concerning possible removal or mitigation of these consequences. The authors provide this information as a useful reference for readers to facilitate the enhanced safety of modern power equipment through qualitative evaluation of design and flow parameters and subsequent selection of the optimal means for increasing flow stability.
A dying man cautiously unravels the mysteries of memory and creation. Vadim is a Russian émigré who, like Nabokov, is a novelist, poet and critic. There are threads linking the fictional hero with his creator as he reconstructs the images of his past from young love to his serious illness. • "Good farce throbbing with his well-known obsessions." -V.S. Pritchett, The New York Review 'Look at the harlequins ... Play! Invent the world! Invent reality'. This is the childhood advice given by an aunt to Russian born writer Vadim Vadimovich, who emigrates to England, then Paris, then Germany and then the US. Now dying, he reconstructs his past. He remembers Iris his first wife, Annette his long-necked typist, and Bel his daughter, as well as his own bizarre illness, 'numerical nimbus syndrome'.

The volume concludes by examining society systems with emphasis on the problems of sustainable development.
Astronomy and Astrophysics Abstracts, which has appeared in semi-annual volumes since 1969, is devoted to the recording, summarizing and indexing of astronomical publications throughout the world. It is prepared under the auspices of the International Astronomical Union (according to a resolution adopted at the 14th General Assembly in 1970). Astronomy and Astrophysics Abstracts aims to present a comprehensive documenta tion of literature in all fields of astronomy and astrophysics. Every effort will be made to ensure that the average time interval between the date of receipt of the original literature and publication of the abstracts will not exceed eight months. This time interval is near to that achieved by monthly abstracting journals, compared to which our system of accumu lating abstracts for about six months offers the advantage of greater convenience for the user. Volume 32 contains literature published in 1982 and received before February 11, 1983; some older literature which was received late and which is not recorded in earlier volumes is also included. We acknowledge with thanks contributions to this volume by Dr. J. Bou~a, Prague, who surveyed journals and publications in Czech and supplied us with abstracts in English.
This book describes adaptive methods of statistical numerical analysis using evaluation of integrals, solution of integral equations, boundary value problems of the theory of elasticity and heat conduction as examples.The results and approaches provided in this book are different from those available in the literature as detailed descriptions of the mechanisms of adaptation of statistical evaluation procedures, which accelerate their convergence, are given.
This book discusses issues of geoecological (GER) and geopolitical (GPR) risks due to hydrocarbon development of the Arctic. The authors explain the ethical and philosophical foundations of understanding environmental equity and justice in relation to the development of Arctic natural resources and consider various approaches to the moral aspects of making global management decisions in the field of environmental protection and environmental safety. Special attention is paid to analysis of modern geopolitical and geostrategic challenges to the development of the Arctic region. The monograph identifies the key geopolitical factors affecting the sustainable development of the Arctic and analyzes the similarities and differences in the geostrategic positions of the five Arctic states. The authors reveal the need to consider geopolitical challenges in the process of GER analysis for oil and gas development in the Arctic region. The book explores the intersection of the strategic interests for a number of states and describes Russia's inability to ensure environmental safety in the development of Arctic deposits. The book analyzes in detail each type of GER with an emphasis on their potential to lead to additional opportunities and threats, and assesses environmental rating as an indicator of the GER management process of Russian oil and gas companies operating in the Arctic. Although the main focus is on the Russian part of this region, many arguments and conclusions are quite applicable to the entire Arctic region. The consideration of geoecological and geopolitical aspects of the development of Arctic resources with the example of Russian oil and gas companies sheds light on the entire Arctic region, taking into account the interests of all other national and international companies involved in GER and GPR there.
Professor Kondratyev and his team consider the concept of global warming due to the greenhouse effect and put forward a new approach to the problem of assessing the impact of anthropogenic processes. Considering data on both sources and sinks for atmospheric carbon and various conceptual schemes of the global carbon dioxide cycle, they suggest a new approach to studies of the problem of the greenhouse effect. They assess the role of different types of soil and vegetation in the assimilation of carbon dioxide from the atmosphere, and discuss models of the atmosphere ocean gas exchange and its role in the carbon dioxide cycle, paying special attention to the role of the Arctic Basin. The authors also consider models of other global atmospheric cycles for a range of atmospheric constituents, and conclude by drawing together a range of scenarios on modelling the global carbon cycle.
This book provides the first comprehensive analysis of how aerosols form in the atmosphere through in situ processes as well as via transport from the surface (dust storms, seas spray, biogenic emissions, forest fires etc.). Such an analysis has been followed by the consideration of both observation data (various field observational experiments) and numerical modeling results to assess climate impacts of aerosols bearing in mind that these impacts are the most significant uncertainty in studying natural and anthropogenic causes of climate change.

This book is about the early era of the Russian space challenge. It is based on the notes of Vladimir Suvorov, a distinguished chief documentary cinematographer, who eyewitnessed and described in his top secret diary all these events from 1959 to 1969. He and his team made 35 films on the Russian conquest of space. He worked closely with the key scientists including Chief Designer Sergey Korolev, the President of the Academy of Sciences Mstislav Keldish and other high ranking military officers who were in charge of the Soviet space program. Many cosmonauts, especially the first ones like Yuri Gagarin, German Titov, et al., became his friends. This book is the first close up and personal account of these remarkable events.
