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 The core of the book is an unpublished manuscript by Karl Kollmann, who was a prominent engineer at Daimler-Benz before and during the war.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 Drawing upon previously unpublished material from the archived German documents, those chapters provide a concise but technically precise and informative look into those technologies, where great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.

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.

This is a magisterial new account of the day-to-day practice of Russian criminal justice in the seventeenth and early eighteenth centuries. Nancy Kollmann contrasts Russian written law with its pragmatic application by local judges, arguing that this combination of formal law and legal institutions with informal, flexible practice contributed to the country's social and political stability. She also places Russian developments in the broader context of early modern European state-building strategies of governance and legal practice. She compares Russia's rituals of execution to the 'spectacles of suffering' of contemporary European capital punishment and uncovers the dramatic ways in which even the tsar himself, complying with Moscow's ideologies of legitimacy, bent to the moral economy of the crowd in moments of uprising. Throughout, the book assesses how criminal legal practice used violence strategically, administering horrific punishments in some cases and in others accommodating with local communities and popular concepts of justice.

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. Als Mitgrunder von AutoScout24 gehoerte er zu den Pionieren der deutschen Internet-Grunderszene. Er konzipierte 2004 die erste mobile UMTS-App in Deutschland, wurde 2012 zum Business Angel des Jahres gewahlt und sitzt u.a. im Aufsichtsrat von Kloeckner & Co SE. Laut dem Magazin Business Punk (02/2014) zahlt er zu den 50 wichtigsten Koepfen der Startup-Szene in Deutschland. Dr. Holger Schmidt ist Chefkorrespondent mit Schwerpunkt Internet des Magazins FOCUS in Berlin. Zuvor hat er 14 Jahre fur die Frankfurter Allgemeine Zeitung uber die digitale OEkonomie berichtet und dort die woechentliche Sonderseite "Netzwirtschaft" verantwortet. Als Internet-Koordinator war er fur die Zusammenarbeit Print/Online zustandig. Sein Blog "Netzoekonom" gehoert zu den meistgelesenen Publikationen der Digitalen Wirtschaft in Deutschland.

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."

The geologie term "'Tethys" introduced by Eduard Suess (1893) into Reience waR originally a paleogeographic one. Since its original des- eription it has been used in various ways. One of them is Tethys as a paleo-biogeographie eoneept. This eoneept was adopted for IGCP Project 262, Tethyan Cretaeeous Correlation. It was proposed by G. CSASZAR and Heim; A. KOLLMANN and has been approved by the IGCP Board in February 1987. The projeet haR its aimH primarily in the improvement of the stra- tigraphie cOl'relation between the heterogenous faeies of the Tethyan realm. The requests to paleontology in this programme are of variouR kindH: The delimitation of the Tethyan realm in spaee and time needH a dear statements on the eomposition of Tethyan faunal 01' floral assem- blages. Riozones based on various fossil groups have to be eRtablished fOI' biostratigraphie eorrelation. Finally, Tethyan bioprovinees have to be established. TheHe problems have been diseussed in a special meeting of the palaeontologieal group of the projeet whieh was held on January 25-27, 1988, in Vienna. Papers presented at this meeting are published in this volume. Heinz A. KOLI.MANN 1. Cretaceous Tethys versus Mesogee Xew Aspects on Tethyan Cretaceous Fossil Assemblages.
