This book is a unique blend of history, technology review, theoretical fundamentals, and design guide. The subject matter is primarily piston aeroengine superchargers - developed in Germany during the Second World War (WWII) - which are centrifugal compressors driven either by the main engine crankshaft or by an exhaust gas turbine. The core of the book is an unpublished manuscript by Karl Kollmann, who was a prominent engineer at Daimler-Benz before and during the war. Dr. Kollmann's manuscript was discovered by Calum Douglas during his extensive research for his earlier book on piston aeroengine development in WWII. It contains a wealth of information on aerothermodynamic and mechanical design of centrifugal compressors in the form of formulae, charts, pictures, and rules of thumb, which, even 75 years later, constitute a valuable resource for engineering professionals and students. In addition to the translation of the original manuscript from German, the authors have completely overhauled the chapters on the aerothermodynamics of centrifugal compressors so that the idiosyncratic coverage (characteristic of German scientific literature at that time) is familiar to a modern reader. Furthermore, the authors added chapters on exhaust gas turbines (for turbo-superchargers), piston aeroengines utilizing them, and turbojet gas turbines. Drawing upon previously unpublished material from the archived German documents, those chapters provide a concise but technically precise and informative look into those technologies, where great strides were made in Germany during the war. In summary, the coverage is intended to be useful not only to history buffs with a technical bent but also to the practicing engineers and engineering students to help with their day-to-day activities in this particular field of turbomachinery.

Autochromes were the first commercial colour photographs. Invented in 1904 by the Lumière brothers Auguste and Louis in Paris, colour photographs caused a great sensation at the time. They were an innovation and the first way to depict the world in true-to-life colour and thus capture it for eternity. This impressive book was compiled by the two authors Dr. Maria Reitter-Kollmann and Dr. Alfred Weidinger. The scholars are leading experts on the history of colour photography at the Oberösterreichische Landes-Kultur GmbH in Linz. The museum holds one of the most important European collections of historical autochromes. The exciting collection consists of more than 1,000 photographs by photographic pioneers such as the Archduchess, Margarethe of Austria-Tuscany or from the collection of Hans Frank, the founder of the first Austrian photo museum in Bad Ischl. Photographs by important photographers such as Auguste Lumière are also part of this unique collection. In the coffee table book Autochrome, the authors present the most beautiful and important pieces from this collection in their full glory. In addition to the wonderful pictures, the book also provides a lot of background knowledge about the technique of this first commercially usable colour photography. Text in English and German.

Modern Russian identity and historical experience has been largely shaped by Russia's imperial past: an empire that was founded in the early modern era and endures in large part today. The Russian Empire 1450-1801 surveys how the areas that made up the empire were conquered and how they were governed. It considers the Russian empire a 'Eurasian empire', characterized by a 'politics of difference': the rulers and their elites at the center defined the state's needs minimally - with control over defense, criminal law, taxation, and mobilization of resources - and otherwise tolerated local religions, languages, cultures, elites, and institutions. The center related to communities and religions vertically, according each a modicum of rights and autonomies, but didn't allow horizontal connections across nobilities, townsmen, or other groups potentially with common interests to coalesce. Thus, the Russian empire was multi-ethnic and multi-religious; Nancy Kollmann gives detailed attention to the major ethnic and religious groups, and surveys the government's strategies of governance - centralized bureaucracy, military reform, and a changed judicial system. The volume pays particular attention to the dissemination of a supranational ideology of political legitimacy in a variety of media - written sources and primarily public ritual, painting, and particularly architecture. Beginning with foundational features, such as geography, climate, demography, and geopolitical situation, The Russian Empire 1450-1801 explores the empire's primarily agrarian economy, serfdom, towns and trade, as well as the many religious groups - primarily Orthodoxy, Islam, and Buddhism. It tracks the emergence of an 'Imperial nobility' and a national self-consciousness that was, by the end of the eighteenth century, distinctly imperial, embracing the diversity of the empire's many peoples and cultures.

This collection of essays offers a series of reflections on the specific literary and cultural forms that can be seen as the product of modernity's spatial transformations, which have taken on new urgency in today's world of ever increasing mobility and global networks. The book offers a broad perspective on the narrative and poetic dimensions of the modern discourses and imaginaries that have shaped our current geographical sensibilities. In the early twenty-first century, we are still grappling with the spatial effects of 'early' and 'high' modern developments, and the contemporary crises revolving around political boundaries and geopolitical orders in many parts of the world have intensified spatial anxieties. They call for a sustained analysis of individual perceptions, cultural constructions and political implications of spatial processes, movements and relations. The contributors of this book focus both on the spatial orders of modernity and on the various dynamic processes that have shaped our engagement with modern space. They creatively engage in a dialogue between literature, cinema, art history, geography, architecture, cultural semiotics and political science, and they transform twentieth- and twenty-first-century theory and philosophy to examine the textual forms of different spatial modernities. The chapters do not only engage with the cartographies, crossings and displacements represented within different texts and media, but are also attentive to the ways in which the latter produce space and perform mobility. Tracing an arc from Thomas More's Utopia to the digital spatiality of contemporary autobiographical film, they treat texts as active cultural forces that crystallize, reinforce, interrogate or complicate the spatial imaginaries of modernity through their own narrative and poetic form.

Dieses Buch zeigt, wie Deutschland als fuhrende Industrienation auch in der Digitalen Wirtschaft ein starker Player werden kann. Deutschland verfugt uber unzahlige Weltmarktfuhrer in den klassischen Wirtschaftsbranchen, bisher aber uber keinen digitalen Champion. Die grossen Player aus dem Internet wie Google, Facebook & Co. dringen zunehmend auch in die realen Wirtschaftsbranchen ein und wollen hier die Spielregeln verandern. Vor diesem Hintergrund analysieren Tobias Kollmann und Holger Schmidt die Rahmenbedingungen eines digitalen Wandels fur unsere Wirtschaft und Gesellschaft, beleuchten die aktuellen Entwicklungen und geben Hinweise auf die notwendigen AEnderungen fur die Zukunft. Im Zentrum stehen die Fragen: Was haben wir aus der bisherigen Digitalisierung gelernt? Wie sieht die aktuelle Digitale Transformation unserer Wirtschaft und Gesellschaft aus? Was ist zu tun, damit wir in Zukunft im digitalen Wettbewerb einen starken Stellenwert erreichen? Oder kurz gesagt: Wie muss ein digitaler Masterplan fur Deutschland aussehen? Die Autoren Prof. Dr. Tobias Kollmann ist Inhaber des Lehrstuhls fur E-Business und E-Entrepreneurship an der Universitat Duisburg-Essen. Er ist Vorsitzender des Beirats "Junge Digitale Wirtschaft" im BMWi und Beauftragter fur die Digitale Wirtschaft in NRW.

The principal author published the first edition of a book entitled in German "Technologie des Holzes" (Springer-Verlag) in the year 1936. This book was available only in photostat copy form in the United States during World War n. A translation into the English language was later made in Australia. Due to many hampering factors caused by World War n it was not unti11951 that the second edition of the first volume of thir:; book with the enlarged title (translated) "Technology of 'Vood and W ood Based Materials" was published. The se co nd volume followed in 1955. The enormOllS expansion of wood seience and technology within less than two deeade,: is evident from a comparison of the number of pages of these two editions. The first edition eomprises 764 pages, the two volumes of the second edition 2231 pages. More recently, it becamc evident that an English version in a condensed up- to-date form was needed. Therefore, the principal author decided to publish a book on "Principles of W ood Science and Technology" in English. The first volume dealt with solid wood, this second volume deals with wood based materials. U sing the ward "Principles" in the title of the condensed book this led directly to abandoning ft11 detailed historie al reviews, explanations, ftnd discussions of mftchines and processes.

Modern forest products research had its start hardly fifty years ago. Today we are in a position to apply the title "wood science" to the field of wood technology that is based on scientific investigation, theoretical as well as experimental. It is this research that fosters new uses for wood as a raw material and that creates the foundation for new industries for the manufacture of wood-base materials such as plywood, laminated products, particle and fiber board and sand wich construction. Wood technology in its broadest sense combines the disciplines of wood anatomy, biology, chemistry, physics and mechanical technology. It is through this interdisciplinary approach that progress has been made in wood seasoning, wood preservation methods, wood machining, surfacing and gluing, and in the many other processes applied in its utilization. In 1936 the senior author published a book entitled, "Technologie des Holzes," which was a first approach to a universal reference book on wood technology. The first edition of Volume I of the Textbook of Wood Technology, co-authored by H. P. BROWN, A. J. P AN SHIN, and C. C. FORSAITH, was published in 1948. An indication of the rapid development of this field can be gained from the fact that the second edition of "Technologie des Holzes und der Holzwerkstoffe," completely revised, was needed by 1951. It contains 2233 pages compared with the 764 pages of the 1936 edition."

Tobias Kollmann and Matthias Hasel explore the manifold possibilities of cross-channel cooperation and present the first systematic investigation and classification of cooperation strategies between partners equipped with online and offline business models. They provide a conceptual framework to understand the subject and examine the practical implications for the implementation of their new concept.

Praktische Probleme der Maschinenakustik sind komplex. Aus diesem Grund wird im vorliegenden Buch vorrangig die indirekte Kette der Schallabstrahlung behandelt. Es werden Berechnungsgleichungen, akustische Messverfahren und konstruktive Massnahmen zur Reduzierung der indirekten Abstrahlung von Gerauschen vorgestellt. Ausgehend von den im Inneren einer Maschine wirkenden dynamischen Kraften werden die Anregung von Korperschall und dessen Abstrahlung von der Oberflache der Maschine behandelt."

Religioese Phanomene und Inhalte ubersteigen oft unsere Wortgewandtheit und bedurfen einer differenzierten Ausdrucksweise. Die Musik bietet Schulern die Moeglichkeit, einen religioesen Stoff zu vertiefen, um Gefuhle und Gedanken daruber auszudrucken. Vergleiche von Lehrplanen und Schulbuchern von 1954 bis heute zeigen, dass der Gesang die christliche UEberlieferungstradition bestimmt hat. Welchen religionspadagogischen Wert Musik heute im Religionsunterricht haben kann, zeigt eine intensive Analyse der Bereiche Lieder, Instrumente und Hoeren von Musik im Religionsunterricht. Welcher Religionslehrer nutzt jedoch die Chance Musik als Ausdrucksquelle des christlichen Glaubens in seinen Unterricht einzubringen? Eine kritische Stellungnahme zum Thema umfasst die aktuelle Problematik des facherverbindenden Unterrichts von Musik und Religion in der Grundschule.
