To achieve successful solutions to the problems resulting from local, distant and global radioactive fallout after nuclear explosions and accidents and to achieve successful retrospective analyses of the radiation conditions from recent observations, certain information is needed: the distribution of the exposure dose rate in the atmosphere and in a country; the distribution of radionuclides in natural environments and the nuclide composition of the radioactive fallout; the features of formation of the aerosol particle-carriers of the radioactivity and of the nuclide distribution of the particles of different sizes formed under different conditions; the processes involved in the migration of radioactive products in different zones and environments; the external and internal effects of nuclear radiation on human beings.This monograph is devoted to a number of these problems, namely, to studies of the radioactive fallout composition, the formation of the aerosol particles that transport the radioactive products and to the analysis of the external radiation doses resulting from nuclear explosions and/or accidents. Problems of restoration and rehabilitation of contaminated land areas are also touched upon in the monograph. To solve such problems one requires knowledge of the mobility of radionuclides, an understanding of their uptake by plants, their transportation within the food chain and finally their uptake by animal and/or human organisms.The results of many years of study of radioactive fallout from atmospheric and underground nuclear explosions and accidents are summarized in this book. It is intended for various specialists - geophysicists, ecologists, health experts and inspectors, as well as those who are concerned with radioactive contamination of natural environments.
In Chapter 1 the methodological principles of systemization and visualization of multidimensional ecological information for its operational dissemination among potential users are stated. Their realization results in creation of the geographic-and ecologic model of marine basin as an information base for diagnosis of the marine ecosystem state, estimation of consequences of economic activity, and modelling of its changes with the use of mathematical tools. In Chapter 2 the geographic-and-ecological aspects of mathematical modelling of marine ecosystems, the possibilities and peculiarities of the most adequate models, the Russian hydrodynamic model of oil spills "SPILLMOD" and hydroecological model of organogenic compound transformation in the sea, are investigated. In the following six Chapters the examples of practical realization of geographic-and-ecological (as information source) and mathematical (as computing apparatus) modelling at the investigations of specific ecological problems associated with consequences of natural hazards and economic activity on aquatory and within the whole Black Sea basin are given.
A dangerous byproduct of industrial progress is often an increase of pollutants discharged into the environment. These pollutants are often harmful to plants and animals, including humans. They also damage buildings and architectural and cultural monuments. This handbook describes many of the important physico-chemical properties of inorganic and organic substances found in industrial wastes and describes their toxic effects on humans.
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 collaborative book aims to offer a comprehensive introduction to global climate, the way it is currently changing, the role of earth, air and satellite observation and monitoring, and subsequent climate modelling. It focuses on the interaction between natural and anthropogenic human- made change factors. The book emphasizes the importance of capturing climatic data and the use of that data in computer-based climatic modelling.
Space exploration and advanced astronomy have dramatically expanded our knowledge of outer space and made it possible to study the indepth mechanisms underlying various natural phenomena caused by complex interaction of physical-chemical and dynamical processes in the universe. Huge breakthroughs in astrophysics and the planetary s- ences have led to increasingly complicated models of such media as giant molecular clouds giving birth to stars, protoplanetary accretion disks associated with the solar system’s formation, planetary atmospheres and circumplanetary space. The creation of these models was promoted by the development of basic approaches in modern - chanics and physics paralleled by the great advancement in the computer sciences. As a result, numerous multidimensional non-stationary problems involving the analysis of evolutionary processes can be investigated using wide-range numerical experiments. Turbulence belongs to the most widespread and, at the same time, the most complicated natural phenomena, related to the origin and development of organized structures (- dies of different scale) at a definite flow regime of fluids in essentially non-linear - drodynamic systems. This is also one of the most complex and intriguing sections of the mechanics of fluids. The direct numerical modeling of turbulent flows encounters large mathematical difficulties, while the development of a general turbulence theory is hardly possible because of the complexity of interacting coherent structures. Three-dimensional non-steady motions arise in such a system under loss of la- nar flow stability defined by the critical value of the Reynolds number.

What is a Messiah? We have heard this word a lot, echoing down through the centuries. It is used by three major religions on this planet: Christianity, Judaism, and Islam. Who is the Messiah? What is, or what will his purpose be? And if he has already come, then what was his purpose? Will he return? If you ask this question to clerics of the three monotheistic religions, they each will give you a different answer and a different name. Each of these clerics will have a different concept of Messiah. In this book, Messianic Jewish moreh (teacher), cantor, and writer YEHOIAKIN BEN YAOCOV explores each of the concepts in detail, in an easy-to-read format.

The rise of Saladin to power in Egypt is a chapter of both Mediterranean and Islamic history. In the period covered by this study, the second half of the twelfth century, profound changes took place in the Eastern Mediterranean affecting the history of the region. The book is divided into two parts. The first deals with the rise of Saladin to power in Egypt (1169-1174) and offers a new interpretation for the demise of the Fatimid state. The second part deals with topics such as the formation of Saladin's army in Egypt, the creation of the navy and the role of the navy in the battle for Acre. The author also addresses topics such as the religious policies of Saladin in Egypt and his attitudes toward the non-Muslim communities.
