“In 1968 we celebrated the one hundred and fiftieth anniversary of the birth of Karl Marx. We still have reason to hope for a concrete celebration in 2018” With a demonstrably thorough grasp of Marxist thought, and seemingly effortless literary flair, Ernst Bloch provides both the well-versed reader and the novice a truly enjoyable introduction to one of the most influential thinkers in history.
Modeling molecular structures is a useful tool for the description, classification and understanding of molecules – species, which have already been synthesized, and others existing only in the imagination of the chemist. The first part of the four–volume series ′Aspects of Organic Chemistry′ focuses on molecular structure, especially that of nucleid acids and proteins. The authors, a team of internationally recognized specialists, present a modern interdisciplinary concept between chemistry – and biology – an approach, which proved to be useful in university education. A unique book, important for both lecturers and students. Subjects of the three remaining volumes are ′Reactivity′, ′Synthesis′ and ′Methods of Structure Elucidation′.
This is the first English translation of the memoirs of the great German-Jewish theater producer Ernst Josef Aufricht. Aufricht's book is most notable for its insider's account of the Berlin theater scene from the great days of the late 1920s and early 30s. Its range, however, from school years and the military to his time as an actor and then producer, the rise of the Nazis, and finally long years of exile in France and America. The book will be of interest to an academic audience, but its reflections on a period of momentous artistic and political events will expand its appeal to a wider group: those interested in twentieth-century German history, music and theater history, as well as the general reader. Benjamin Bloch is a clinical psychologist who grew up speaking German at home with his native German father and studied German and English Literature."--Provided by publisher.
Natural and Synthetic Waxes A compilation of all relevant information for the production and use of waxes in technical applications Waxes are among the oldest organic substances used by mankind. Before all others, beeswax is known to have played a role in human history for thousands of years. But over time, many other wax species have been detected and exploited, and prepared for different utilizations. Today, we possess knowledge of a great variety of different types of waxes. Unfortunately, there still is no broadly accepted definition of a wax: for the relatively few wax chemists, waxes are usually defined by their physico-chemical properties more than by their chemical constitution. Waxes are not uniform but oligomeric and polymeric substances, not simply describable with a chemical formula. The realm of waxes encompasses fully or partly natural, refined, partly or fully synthetic products, which can be extended by “wax-like” products which do not fulfil all definition criteria. Waxes are offered in different forms like pellets, granules, powders, or micropowders. Their number of technical applications runs into thousands. However, waxes in most cases are just adjuvants or additives, and with few exceptions like candles not known to a broader public. Only few publications over the last decades tried to present a more comprehensive overview of heir chemistry, chemical composition, their physical and analytical properties, their applications, and their sometimes astonishing history. Based on personal experience and expertise, the authors intend to present an overview on the main classes of waxes, their origin, history, future, and potential fate. Economical aspects like market size and development, ecological impacts and challenges, and regulatory issues are also addressed. Waxes are indispensable products in everyday life and in industry and technology, though mostly not even visible or distinguishable to experts. They deserve more than the role of a “poor cousin” in chemistry and technology.
A canonical quantization approach to classical field theory, this text is suitable for mathematicians interested in theoretical physics as well as to theoretical physicists who use differential geometric methods in their modelling. Introduces differential geometry, the theory of Lie groups, and progresses to discuss the systematic development of a covariant Hamiltonian formulation of field theory. 1988 edition.
One might well ask why another volume dealing with biological aspects of compounds of fluorine should be offered to the scientific community, already burdened with a literature too massive to be comfortably ingested. Prior toW orld War II this question simply did not arise: there was not sufficient interest or literature in the field to warrant anything beyond the classical monograph pub 1 lished by KAJ RoHOLM in 1937 • RoHOLM's work was directed chiefly toward a better understanding of the effects of fluorides on the general health of workers in the cyrolite industry. However, with the demonstration that water-borne fluoride was a causative agent of both mottled enamel and increased resistance to dental caries, the ground work was laid in the 1930's and early 1940's for a greatly increased interest in the biological effects of fluorides in human beings. During this time and earlier for that matter, work also had been going steadily ahead in the less spectacular area of effects produced in poultry and livestock when fluorine-containing rock phosphate was incorporated in the ration, and when pasture land was contami nated with fluorides released during the large-scale conversion of rock phosphate to fertilizer and phosphoric acid. These latter aspects of the problem had led to the development of a respectable literature in plant physiology, dealing with the effects of fluoride on vegetation.
It is November 1918. Germany has just surrendered after four years of the most savage warfare in history. It is teetering on the brink of total social and economic collapse, and the German people now lie at the mercy of new, liberal politicians who despise everything Germany once stood for. The Communists are rioting in the streets, threatening to topple the new government in Weimar and bring about their own revolution. The frontline soldiers are returning from the hell of the war to find an unrecognizable land, the principles and traditions they had sacrificed so much to defend now the stuff of mockery. The narrator of The Outlaws, a 16-year-old military cadet, is too young to have served in the trenches, but feels the sting of this betrayal no less than they. Since Germany's armies have been all but disbanded, he joins the paramilitary Freikorps - groups of veterans who refuse to lay down their arms, and who have pledged to stop the Communists - and begins fighting, first in the streets of Germany's cities, and then in the Baltic states, defending Germany's eastern frontiers from Communist subversion while ignoring the calls to disengage by the meek politicians at home. After months of intense fighting abroad, the Freikorps soldiers return to settle scores with their enemies in Germany, dreaming of a nationalist counter-revolution, and, their trigger fingers still itchy, fix their sights on bringing down the hated new government once and for all... The Outlaws is a chronicle of the experiences of the men who fought in the Freikorps, but it is also an adventure and a war story about an entire generation of soldiers who loved their homeland more than peace and comfort, and who refused to accept defeat at any price. "What we wanted we did not know; but what we knew we did not want. To force a way through the prisoning wall of the world, to march over burning fields, to stamp over ruins and scattered ashes, to dash recklessly through wild forests, over blasted heaths, to push, conquer, eat our way through towards the East, to the white, hot, dark, cold land that stretched between ourselves and Asia - was that what we wanted? I do not know whether that was our desire, but that was what we did. And the search for reasons why was lost in the tumult of continuous fighting." - p. 65 Ernst von Salomon (1902-1972) was one of the writers of the German Conservative Revolution of the 1920s. Like the narrator of The Outlaws, he was a military cadet at the end of the First World War, and joined the Freikorps, participating in many of the events described in the book, including the assassination of Foreign Minister Walther Rathenau, for which he was imprisoned. He went on to write many books and film scripts.
The only book that gets close to defining who Anne Frank was. Her father Otto Frank initiated this project and the author interviewed 42 people mentioned in her diary. Here too is the story of the betrayal and its disastrous aftermath.
This book presents the early history of psychoanalysis, focusing on the network of psychoanalytic "filiations" and the context of discovery of crucial concepts, such as Freud's technical recommendations, the therapeutic use of countertransference, and the psychotherapeutic treatment of psychoses.
The plays collected within this volume are social dramas and tragedies. They bear witness to human suffering, and to fine yet vain struggles to vanquish this suffering. Four of these plays were written in prison, others were banned. This early work by Ernst Toller was originally published in 1934, we are now republishing it with a brand new introductory biography.
Explores the development of the ideas of evolutionary biology, particularly as affected by the increasing understanding of genetics and of the chemical basis of inheritance.
HIS BOOK CONTAINS a most comprehensive text that presents syntax-directed and compositional methods for the formal veri?- T cation of programs. The approach is not language-bounded in the sense that it covers a large variety of programming models and features that appear in most modern programming languages. It covers the classes of - quential and parallel, deterministic and non-deterministic, distributed and object-oriented programs. For each of the classes it presents the various c- teria of correctness that are relevant for these classes, such as interference freedom, deadlock freedom, and appropriate notions of liveness for parallel programs. Also, special proof rules appropriate for each class of programs are presented. In spite of this diversity due to the rich program classes cons- ered, there exist a uniform underlying theory of veri?cation which is synt- oriented and promotes compositional approaches to veri?cation, leading to scalability of the methods. The text strikes the proper balance between mathematical rigor and - dactic introduction of increasingly complex rules in an incremental manner, adequately supported by state-of-the-art examples. As a result it can serve as a textbook for a variety of courses on di?erent levels and varying durations. It can also serve as a reference book for researchers in the theory of veri?- tion, in particular since it contains much material that never before appeared in book form. This is specially true for the treatment of object-oriented p- grams which is entirely novel and is strikingly elegant.
In this volume, Ernst Troeltsch embraces historical relativity while rejecting historical relativism, and thereby provides a model for the philosophy of history. The volume remains as relevant as it was in 1923"--
This classic introduction to textual criticism of the Hebrew Bible is now entirely updated. The book examines the transmission of the biblical text in its original languge, the history of its translation, the causes of corruption in the textual tradition, and the proper principles and techniques of textual criticism.
This work, published in two volumes, contains descriptions of the wood and bark anatomies of 3000 dicotyledonous plants of 120 families, highlighting the anatomical and phylogenetic diversity of dicotyledonous plants of the Northern Hemisphere. The first volume principally treats families of the Early Angiosperms, Eudicots, Core Eudicots and Rosids, while the second concentrates on the Asterids. Presented in Volume 1 are microsections of the xylem and phloem of herbs, shrubs and trees of 1200 species and 85 families of various life forms of the temperate zone along altitudinal gradients from the lowland at the Mediterranean coast to the alpine zone in Western Europe. The global perspective of the findings is underlined by the analysis of 500 species from the Caucasus, the Rocky Mountains and Andes, the subtropical zone on the Canary Islands, the arid zones in the Sahara, in Eurasia, Arabia and Southwest North America, and the boreal and arctic zones in Eurasia and Canada. The presence of annual rings in all life forms demonstrates that herbs and dwarf shrubs are an excellent tool for the reconstruction of annual biomass production and the interannual dynamic of plant associations. The common principle of the anatomical expression of secondary growth is a key factor in understanding evolution and adaptation processes in all life forms, from the 2 cm tall whitlow grass (Draba arctica) in the arctic to the 40 m tall beech (Fagus sylvatica) in Central European managed forests. The study opens vast fields of research for dendrochronology, wood anatomy, taxonomy and ecology.
Beginning in 1949, the German novelist and essayist Ernst Jünger began a correspondence with the philosopher Martin Heidegger that lasted until Heidegger’s death in 1975. This volume contains the first English translation of their complete correspondence, as well as letters from Heidegger’s wife and son and others referred to in their correspondence. It also contains a translation of Jünger’s essay Across the Line (Über die Linie), his contribution to a Festschrift celebrating Heidegger’s sixtieth birthday. Jünger’s and Heidegger’s correspondence is of enormous historical interest, revealing how both men came to understand their cultural roles in post-war Europe. It is valuable as well for showing the emergence of themes pervasive in Heidegger’s post-war thought: his cultural and political pessimism and his concern with the problem of global technology. The correspondence also reveals the evolution of a philosophical friendship between two writers central to twentieth century European thought, and the mutual influence that friendship worked on their writing.

This book describes the state-of-the-art use of biological insulating liquids in detail. In recent years, more and more transformers filled with esters have been put into operation. This is because people recognize the benefits of ester liquids in terms of their fire safety (high flash and fire points) and environmental characteristics, judging from their biodegradability, their low CO2 footprint (only valid for natural ester) and their beneficial interactions with solid insulation, etc. One of the main reasons is that the water adsorption and absorption characteristics of these liquids are excellent and very different compared to mineral oil. The today’s discussion about climate change and global warming is an additional driver for using natural ester. Another advantage is that transformers filled with biological insulating liquids can operate with an overload of up to 150%. This is advantageous in the case of volatile energy generation from wind and solar power and in the supply of electrical energy for electromobility. Liquid inside electrical equipment is the lifeblood that serves both as a dielectric and a cooling medium. Some properties of these liquids differ from mineral oil, which had to be considered in the transformer design. The dielectric liquid is always in direct contact with transformer materials; therefore, the interaction should be very well understood, especially when retrofilling an existing mineral oil filled device. There are several natural ester fluids derived from various seeds and fruits on the market, and their properties may differ more or less. In the book, the most important properties of the different biological insulating fluids and mineral oil are compared. Ester fluids have already found their way into various standards. The condition of the device can be verified very well from the contents of the insulating liquids. For analysis and testing, the same equipment and devices that are commonly used for mineral oil are used for ester liquid. The chemical and physical behaviors of ester fluids compared to mineral oil are different. This must always be considered when interpreting test results stemming from ester fluids. The book is a guideline for students, original equipment manufacturers, users, laboratories and authorities in the use of biological insulating liquids.
Scientific reserach implies progress. Sometimes, however, progress merely consists of a step back to the past, as in the case of the dating of the Prochiron, one of the Byzantine law books dealt with in this study. Recently, progress seemed to imply that the Prochiron had been issued by Leo the Wise in the year 907. This book sets out to show that the Prochiron was promulgated by Basil the Macedonian in the years 870-879, thus confirming the view of Karl Eduard Zachariä von Lingenthal, one of the first scholars who paved a way in the ‘ungodly jumble’ of Byzantine law books. Of course, the present study does not exclusively deal with the dating of law books: their status appeared to be inextricably bound up with their dating. Moreover, recent research has come up with results that shed new light on the Basilica and the Novels of Leo the Wise. Reason enough to investigate Leo’s legislative intentions..... To date and not to date, that is the issue in the realm of Byzantine legal history.
Describes and interrelates the following processes: cooperative alpha processes in a cold liquid, structural relaxation in the glass near Tg, the Johari-Goldstein beta process, the Williams-Götze process in a warm liquid, fast nonactivated cage rattling and boson peak, and ultraslow Fischer modes.
This study appears at a time when a decisive turn is due in the research on personality development. After many years of stagna tion and misguided research in this field, this book should lead to a thorough revision and a better understanding of current views on the factors which have an influence on personality. Let us consider the unsatisfactory aspects of the recent develop ments in personality studies. At the beginning of this century, the revolutionary insight gained ground that personality is susceptible to various influences, in particular to those resulting from human interaction. This insight swept away many of the old scholastic concepts and gained special importance in the fields of pedagogics and psychotherapy. How ever, in the wake of every great discovery we find inherent dangers. For years, various claims and creeds on the malleability of personality have been put forward as if they were proven facts. Lay literature, too, was permeated with wrong and distorted information on factors which might endanger child development.
The International System of Units (SI) is the world's most widely used system of measurement, used every day in commerce and science, and is the modern form of the metric system. It currently comprises the meter (m), the kilogram (kg), the second (s), the ampere (A), the kelvin (K), the candela (cd) and the mole (mol)). The system is changing though, units and unit definitions are modified through international agreements as the technology of measurement progresses, and as the precision of measurements improves. The SI is now being redefined based on constants of nature and their realization by quantum standards. Therefore, the underlying physics and technologies will receive increasing interest, and not only in the metrology community but in all fields of science. This book introduces and explains the applications of modern physics concepts to metrology, the science and the applications of measurements. A special focus is made on the use of quantum standards for the realization of the forthcoming new SI (the international system of units). The basic physical phenomena are introduced on a level which provides comprehensive information for the experienced reader but also provides a guide for a more intense study of these phenomena for students.
This textbook covers Plant Ecology from the molecular to the global level. It covers the following areas in unprecedented breadth and depth: - Molecular ecophysiology (stress physiology: light, temperature, oxygen deficiency, drought, salt, heavy metals, xenobiotica and biotic stress factors) - Autecology (whole plant ecology: thermal balance, water, nutrient, carbon relations) - Ecosystem ecology (plants as part of ecosystems, element cycles, biodiversity) - Synecology (development of vegetation in time and space, interactions between vegetation and the abiotic and biotic environment) - Global aspects of plant ecology (global change, global biogeochemical cycles, land use, international conventions, socio-economic interactions) The book is carefully structured and well written: complex issues are elegantly presented and easily understandable. It contains more than 500 photographs and drawings, mostly in colour, illustrating the fascinating subject. The book is primarily aimed at graduate students of biology but will also be of interest to post-graduate students and researchers in botany, geosciences and landscape ecology. Further, it provides a sound basis for those dealing with agriculture, forestry, land use, and landscape management.
The first volume contains species accounts of the venomous lizards and elapid and viperid snakes found north of Mexico's twenty-fifth parallel. Volume two covers the twenty-one species of rattlesnakes found in the United States, Canada, and northern Mexico.
