First published in 1988 and now known as a classic. In this book Stephen Fry describes, in bench-top detail, techniques for the study of primary cell walls in higher plants. Deepening interest in the chelistry and metabolism of cell walls reflects the breadth of their significance in biology. Walls play crutial roles in morphogenesis, growth, disease-resistance, recognition, signalling, digestibility, nutrition and decay. Scientists interested in questions concerning these processes need to know about methods of cell wall analysis. This book was written with these people in mind. There are 11 chapters as follows: 1. Introduction to the growing plant cell wall 2. Radioactive labelling of cell walls 3. Wall polymers: extraction and fractionation 4. Wall polymers: chemical characterisation 5. Wall biosyntesis 6. Wall enzymes 7. Wall architecture 8. Wall turnover and sloughing 9. Biologically-active wall oligosaccharides 10. Wall tightening and loosening: growth 11. Wall degradation "Stephen Fry has written an invaluable book on the analytical techniques available in this important research field. This is an excellent book for the typical modern biologist." J. Experimental Biology "This book will be of considerable value to anyone engaged in the analysis of plant cell walls." Ann. Botany "For those who intend to do any practical cell wall analysis this book will be an invaluable laboratory manual." Plant Pathology "As a practical guide to wall analysis this book will be a most valuable tool." Times Higher Education Supplement

In this modern era of mathematical modeling, applications have become increasingly complicated. As the complexity grows, it becomes more and more difficult to draw meaningful conclusions about the behavior of theoretical models and their relations to reality. Alongside methods that emphasize quantitative properties and the testing of scientific details, there is a need for approaches that are more qualitative. These techniques attempt to cover whole families of models in one bold stroke, in a manner that allows robust conclusions to be drawn about them. Loop analysis and time averaging provide a means of interpreting the properties of systems from the network of interactions within the system. The authors' methodology concentrates on graphical representation to guide experimental design, to identify sources of external variability from the statistical pattern of variables, and to make management decisions. Although most of the examples are drawn from ecology, the methods are relevant to all of the pure and applied sciences. This relevance is enhanced by case studies from such diverse areas as physiology, resource management, the behavioral sciences, and social epidemiology. The book will be useful to a broad readership from the biological and social sciences as well as the physical sciences and technology. It will interest undergraduate and graduate students along with researchers active in these disciplines. Here the reader will find a strong rationale for maintaining a holistic approach, revealing what insights and advantages are retained by the broader perspective and, more explicitly, by the synergistic effects that cannot be discerned by reducing systems to their smallest parts.

This is the first book to explore the effect of genetic research on the Lemba Judaising community of Southern Africa and the phenomenon of Israelite identity. The science of genetics as relayed by the media is perceived by laymen as being irreproachably objective 'hard science': its disinterested 'scientific' findings appear immensely impressive and may therefore act as a powerful catalyst for change. In this case, an oral tradition cherished by many of the Lemba that they are of Jewish origin appears to be supported by recent DNA testing, which has deeply affected the narrative and religious identity of the group and the way the tribe is perceived in the Western world. International in appeal, this topical text brings together cutting-edge research on the social, cultural and ethical implications of genetics and the study of Judaising movements across the world. This book will be of interest to researchers and students of Jewish history, genetic anthropology, race and ethnicity studies, and religious and cultural studies.

This volume contains material first presented at an international workshop on the 'Use of Microorganisms to Combat Pollution', held in Israel, May 10--18, 1992. The workshop was sponsored by the Bat-Sheva de Rothschild Foundation for the Advancement of Science and included microbiologists, biochemists and geneticists from universities, environmental agencies and the military. Each of the contributors to this volume is an ack nowledged expert on the treatment of one or more types of pollution using microorganisms or their enzymes. This book differs from most published symposia proceedings in the breadth of coverage of each subject. Most of the chapters are divided into three parts: (a) A general presentation of the source and toxicity of the pollutant, (b) a review of the current state-of-the-science on the biodegradation of that pollutant and (c) the authors' unique research experiences on the problem. In several examples, the authors have presented data from both laboratory studies and field trials. Thus, the book contains not only the theoretical background on the biodegradation of pollutants, but also practical experiences in applying this knowledge to solving significant pollution problems.

Humanity is a part of Nature, yet every thinking person at one time or another asks herself or himself, "How did we get here? What makes me different from the rest of Nature?" In The Course of Nature an artist and a scientist ask those questions with full respect for all contexts, both scientific and not. Amy Pollack's figures stand on their own as elegant summaries of one or another aspect of Nature and our place in it. Robert Pollack's one-page essays for each illustration lay out the underlying scientific issues along with the overarching moral context for these issues. Together the authors have created a door into Nature for the non-scientist, and a door into the separate question of what is right, for both the scientist and the rest of us.

Rapid advances in the physical and biological sciences and in related technologies have brought about equally farreaching changes in mathematical research. Focusing on control theory, invariant imbedding, dynamic programming, and quasilinearization, Mr. Bellman explores with ease and clarity the mathematical research problems arising from scientific questions in engineering, physics, biology, and medicine. Special attention is paid in these essays to the use of the digital computer in obtaining the numerical solution of numerical problems, its influence in the formulation of new and old scientific problems in new terms, and to some of the effects of the computer revolution on educational and social systems. The new opportunities for mathematical research presage, Bellman concludes, a renaissance of mathematics in human affairs by involving it closely in the problems of society.

2018 Reprint of 1962 Edition. Full facsimile of the original edition, not reproduced with Optical Recognition software. Bookchin wrote Our Synthetic Environment under the pseudonym Lewis Herber. This was one of the first books of the modern period in which an author espoused an ecological and environmentalist worldview. It predates Silent Spring (1962) by Rachel Carson, a more widely known book on the same topic widely credited as starting the environmental movement. "At the time of its publication, Our Synthetic Environment was the most comprehensive and enlightened book on the environmental crisis. Many other books on this topic have been published since, but none, I believe, as comprehensive." --René Dubos

Menaḥem Mendel Schneerson (1902-1994) was the seventh and seemingly last Rebbe of the Habad-Lubavitch dynasty. Marked by conflicting tendencies, Schneerson was a radical messianic visionary who promoted a conservative political agenda, a reclusive contemplative who built a hasidic sect into an international movement, and a man dedicated to the exposition of mysteries who nevertheless harbored many secrets. Schneerson astutely masked views that might be deemed heterodox by the canons of orthodoxy while engineering a fundamentalist ideology that could subvert traditional gender hierarchy, the halakhic distinction between permissible and forbidden, and the social-anthropological division between Jew and Gentile. While most literature on the Rebbe focuses on whether or not he identified with the role of Messiah, Elliot R. Wolfson, a leading scholar of Jewish mysticism and the phenomenology of religious experience, concentrates instead on Schneerson's apocalyptic sensibility and his promotion of a mystical consciousness that undermines all discrimination. For Schneerson, the ploy of secrecy is crucial to the dissemination of the messianic secret. To be enlightened messianically is to be delivered from all conceptual limitations, even the very notion of becoming emancipated from limitation. The ultimate liberation, or true and complete redemption, fuses the believer into an infinite essence beyond all duality, even the duality of being emancipated and not emancipated--an emancipation, in other words, that emancipates one from the bind of emancipation. At its deepest level, Schneerson's eschatological orientation discerned that a spiritual master, if he be true, must dispose of the mask of mastery. Situating Habad's thought within the evolution of kabbalistic mysticism, the history of Western philosophy, and Mahayana Buddhism, Wolfson articulates Schneerson's rich theology and profound philosophy, concentrating on the nature of apophatic embodiment, semiotic materiality, hypernomian transvaluation, nondifferentiated alterity, and atemporal temporality.

These companion volumes, long out of print, are now presented together for the first time so that the reader may better grasp their essential unity. In Ether, God and Devil, Wilhelm Reich describes the process of functional thinking and reveals how the inner logic of this objective thought technique led him to the discovery of cosmic orgone energy. In Cosmic Superimposition , Reich steps beyond the character structure of man to an understanding of how man is rooted in nature. The super-imposition of two orgone-energy systems which is demonstrable in the genital embrace is revealed as a common functioning principal that exists in all of nature. Concluding this work, Reich returns to the human sphere "to ponder about the greatest riddle of all: the ability of man to think, and by mere thinking to know what nature is and how it works."

Neurophysiologists are often accused by colleagues in the physical sci ences of designing experiments without any underlying hypothesis. This impression is attributable to the ease of getting lost in the ever-increasing sea of professional publications which do not state explicitly the ultimate goal of the research. On the other hand, many of the explicit models for brain function in the past were so far removed from experimental reality that they had very little impact on further research. It seems that one needs much intimate experience with the real nerv-. ous system before a reasonable model can be suggested. It would have been impossible for Copernicus to suggest his model of the solar system without the detailed observations and tabulations of star and planet motion accu mulated by the preceeding generations. This need for intimate experience with the nervous system before daring to put forward some hypothesis about its mechanism of action is especially apparent when theorizing about cerebral cortex function. There is widespread agreement that processing of information in the cor tex is associated with complex spatio-temporal patterns of activity. Yet the vast majority of experimental work is based on single neuron recordings or on recordings made with gross electrodes to which tens of thousands of neurons contribute in an unknown fashion. Although these experiments have taught us a great deal about the organization and function of the cor tex, they have not enabled us to examine the spatio-temporal organization of neuronal activity in any detail.

In the dynamics of mankind one can trace out a path of contemplation about the "world", leading from early speculations to today's natural sciences. The endeavour to understand how nature works has led to the construction, still in progress, of an abstract building of great com plexity. To the uninitiated it may look more like a scurrilous sculpture resting on many legs, among them such peculiar ones as probability, relativity, quantum mechanics .... At times problems with the stabil ity of the building or sculpture arise: known facts that won't fit and can no longer be ignored start to undermine the foundations. Then new footings are thought of, constructed and finally cast. In fact, the undermining and casting is often done in one step. This process has already been repeated many times and will un doubtedly repeat itself again and again. At present, one recognizable footing under construction goes by the name of "chaos theory". Physi cists seem to like the word chaos. When they came to recognize that the air is not just empty space but an obviously indescribable dance of myriads of molecules they called that "chaos". What else would fit? In the course of time the name was simplified to "gas". Thus the word chaos became free to serve for the next upsetting experience. That arose in the context of nonlinear dynamical systems, where peculiar motions were detected, ones seemingly beyond human comprehension.

The Negev , first published over a decade ago, told the story of some twenty years of study of southern Israel's desert. It synthesized the findings of botanists, geologists, soil scientists, agronomists, archaeologists, historians, and engineers and told how the applications of their work produced an agricultural surplus in this forbiddingly dry, hot region. , Now Michael Evenari has amplified the book with data from another decade of work. He describes the efforts at a new farm at Wadi Mashash, extends the weather data another ten years, presents further work on the adaptations of plants and animals to desert conditions, and takes a much deeper look at the historical precedents for the method of runoff agriculture, which has made the desert bloom.
