Faith in a Seed contains the hitherto unpublished work The Dispersion of Seeds, one of Henry D. Thoreau's last important research and writing projects, and now his first new book to appear in 125 years.

With the remarkable clarity and grace that characterize all of his writings, Thoreau describes the ecological succession of plant species through seed dispersal. The Dispersion of Seeds, which draws on Charles Darwin's theory of natural selection, refutes the then widely accepted theory that some plants spring spontaneously to life, independent of roots, cuttings, or seeds. As Thoreau wrote: "Though I do not believe a plant will spring up where no seed has been, I have great faith in a seed. Convince me that you have a seed there, and I am prepared to expect wonders.".

This completely updated and revised Second Edition of the popular Workbook of Atmospheric Dispersion Estimates provides an important foundation for understanding dispersion modeling as it is being practiced today. The book and accompanying diskette will help you determine the impacts of various sources of air pollution, including the effects of wind and turbulence, plume rise, and Gaussian dispersion and its limitations. Information is shown in summary graphs as well as in equations. The programs included on the diskette allow you to "get the feel" for the results you'll obtain through the input of various combinations of parameter values. The sensitivity of data to various parameters can be easily explored by changing one value and seeing the effect on the results. The book presents 37 example problems with solutions to show the estimation of atmospheric pollutant concentrations for many situations. .

Egypt’s indigenous Jewish population comprised Arabic-speaking Rabbanite and Karaite Jews, some of whom had been in the country since the early Islamic era. The Jews expelled from Spain in 1492 took refuge in Egypt, and Sephardic immigrants augmented their numbers in the midnineteenth century. Originally welcomed elsewhere in the Ottoman Empire, these Spanish Jews came to Egypt seeking economic opportunity in the era of Suez Canal construction and the cotton boom. The late nineteenth century brought Ashkenazi Jews fleeing persecution in Eastern Europe. The different groups formed a heterogeneous community of cosmopolitan hybrids, which were both an element of strength and a factor in its eventual demise.

The Dispersion of Egyptian Jewry examines the history of the Egyptian Jewish community after 1948. It focuses on three major areas: the life of the majority of the community, which remained in Egypt from the1948 Arab-Israeli War until the aftermath of the 1956 Suez/Sinai War; the dispersion and reestablishment of Egyptian Jewish communities in the United States, France, and Israel; and contested memories of Jewish life in Egypt since President Anwar al-Sadat’s visit to Jerusalem in 1977. Fusing history, ethnography, literary analysis, and autobiography, Joel Beinin conducts an interdisciplinary investigation into identity, dispersion, and the retrieval of identity that is relevant for anyone interested in Egypt, the Jewish Diaspora, or the formation of cultures and identities..

Air Pollution Meteorology and Dispersion provides a concise yet thorough review of the basic theories, models, experiments, and observations of pollutant dispersal in the atmosphere. It offers the theoretical and empirical bases of frequently used dispersion models while emphasizing the limitations and uncertainties inherent in these models. Organized into twelve chapters, the material is presented in order of increasing difficulty. The first half of the book treats the basic tenets of air pollution modeling; the second half deals with the more detailed theoretical and observational aspects of dispersion. Sufficient background material on atmospheric structure, dynamics, and circulation systems and their importance to atmospheric dispersion is included for students who do not yet have a strong meteorological background. Turbulence and diffusion theories, such as gradient transport, statistical, and similarity theories, as well as analytical and numerical dispersion and air quality models, are also discussed. Problems and exercises are included in each chapter, making this an ideal text for undergraduate and graduate courses in atmospheric science and mechanical engineering..

Tales from the Sephardic Dispersion begins the most important collection of Jewish folktales ever published It is the first volume in Folktales of the Jews, the five-volume series to be released over the next several years, in the tradition of Louis Ginzberg's classic, Legends of the Jews.

The 71 tales here and the others in this series have been selected from the Israel Folktale Archives (IFA), a treasure house of Jewish lore that has remained largely unavailable to the entire world until now.

Since the creation of the State of Israel, the IFA has collected more than 20,000 tales from newly arrived immigrants, long-lost stories shared by their families from around the world. The tales come from the major ethno-linguistic communities of the Jewish world and are representative of a wide variety of subjects and motifs, especially rich in Jewish content and context.

Each of the tales is accompanied by in-depth commentary that explains the tale's cultural, historical, and literary background and its similarity to other tales in the IFA collection, and extensive scholarly notes. There is also an introduction that describes the Sephardic culture and its folk narrative tradition, a world map of the areas covered, illustrations, biographies of the collectors and narrators, tale type and motif indexes, a subject index, and a comprehensive bibliography.

Until the establishment of the IFA, we had had only limited access to the wide range of Jewish folk narratives. Even in Israel, the gathering place of the most wide-ranging cross-section of world Jewry, these folktales have remained largely unknown. Many of the communities no longer exist as cohesive societies in their representative lands; the Holocaust, migration, and changes in living styles have made the continuation of these tales impossible. This volume and the others to come will be monuments to a rich but vanishing oral tradition..

This work arose from research results of the interdisciplinary centre for scientific computing at the University of Heidelberg as well as of the Humboldt University. The contribution of this work is the simulation of contaminated ground water developed from models about the disposal of severely contaminated material, i.e. radioactive fuels or chemical waste products. The model is based on equations for convection-diffusion-dispersion reactions. The equation in the present book is used for the modelling of a radionuclide transport of pollutants in ground water as well as for chemical irreversible reactions. While solving such problems, so-called multi-scale processes arise. Conventional treatment of black-box discretisation and solution methods are impossible or complicated. Hence, physically motivated methods are used, i.e. to integrate one-dimensional analytical solutions of convection-reaction equations. Especially so-called decomposition methods were emphasized.These methods decouple the different scales and solve the equations based on scales with each other. Therefore the previous coupling errors between the terms of the equations can be controlled and minimised with iterative methods. Furthermore, analytical solutions could be used for comparisons with the numerical solutions. In this work the theoretical derivations of solutions as well as their application in numerical methods for realistic calculations could be acquired. The methods were assembled in a program package that had been developed in a project to evolve a program for modelling the transport of pollutants in ground water. Some realistic damage events could be calculated based on dates from the partner GRS in Braunschweig, Germany..

Rheology of Particulate Dispersions and Composites provides comprehensive coverage of fundamental principles and equations that govern the rheology for particulate dispersions and two-phase solid composites. The rheological properties of suspensions, emulsions, bubbly liquids (foams) and other dispersions appear alongside those of solid composite materials for the first time in this unique, single source.

The first section introduces applications, definitions, and important concepts such as fluid/solid/interfacial mechanics, bulk stress in dispersed systems, and dipole strength of particles. Subsequent chapters systematically consider the rheology for a wide variety of dispersions, including systems of:

Rigid spherical and nonspherical particles (porous, nonporous, neutral, electrically charged, and magnetic particles)

Nonrigid particles (deformable solid particles, droplets, bubbles, capsules, and core–shell particles)

The final sections address the elastic properties of particle- and fiber-reinforced solid composite materials. They also discuss dynamic viscoelastic behavior of particulate dispersions and composites.

From process design to novel materials development, Rheology of Particulate Dispersions and Composites illustrates the need for understanding rheological behavior throughout numerous commercial and industrial applications. This book is a versatile resource for students and scientists from a broad range of disciplines involved in the application, research, and development of dispersed systems..
