Preface “Lecture Notes in Physics”, having a strong publishing history in fundamental physics research, has devoted a special volume to recent developments in the field of physics of rotating fluids and related topics. The present volume will comprise 23 contributed papers on the different aspects of rotating fluids, i.e. Taylor– Couette flow, spherical Couette flow, plane Couette flow, as well as rotating annulus flow. In the seminal paper by G.I. Taylor, a powerful combination of theory and experiment was brought to bear on the stability of flow between rotating cylin- ders, now referred to as Taylor–Couette flow. The significance of his work lies in the fact that here, for the first time, an experiment in fluid dynamics and the theory, using the Navier–Stokes equations, could be compared and led to excel- lent agreement. Since that time ideas associated with rotating flows have been extended and have resulted in classic texts such as Greenspan’s “The theory of rotating fluids”. In this present book we report on modern developments in the field where new mathematical ideas have been applied to experimental observations on a variety of related flow fields. The aim of this volume is to provide the reader with a comprehensive overview of the current state of the art and possible future directions of the Taylor–Couette community and to include related topics and applications. The first part of this volume is devoted to several new results in the classical Taylor–Couette problem covering diverse theoretical, experimental and numeri- cal works on bifurcation theory, the influence of boundary conditions, counter- rotating flows, spiral vortices, time-periodic flows, low dimensional dynamics, ax- ial effects, secondary bifurcations, spatiotemporal intermittency, Taylor–Couette flows with axial and radial flow, Taylor vortices at different geometries and trans- port phenomena in magnetic fluids. The second part of this volume focuses on spherical Couette flows, including isothermal flows, vortical structures, spiral and wavy vortices, the influence of throughflow, thermal convective motions, intermittency at the onset of convec- tion, as well as magneto-hydrodynamics in spherical shells. Further parts are devoted to Goertler vortices and flows along curved sur- faces, rotating annulus flows, as well as superfluid Couette flows, tertiary and quarternary solutions for plane Couette flows with thermal stratification and rotating disk flows. VI Preface We hope that the readers will find this volume useful, giving an overview of the latest experimental and theoretical studies on the physics of rotating fluids. It is a pleasure for us to thank all those who contributed to the conference “11th International Couette–Taylor Workshop” and, by the same token, to this volume. We would like to thank the Dipl. Phys. Oliver Meincke, Markus Junk, Arne Schulz and Jan Abshagen for their invaluable and indispensable help in editing this book. Last, but not least, we are grateful to Dr. Christian Caron for offering to publish this volume in the Springer Series “Lecture Notes in Physics” and for the patient assistance of Mrs. Brigitte Reichel-Mayer.

  • The German North Sea Ports' Absorption Into Imperial Germany, 1866–1914
    From Unification to Integration: The German North Sea Ports' absorption into Imperial Germany, 1866–1914 Henning Kuhlmann Submitted for the award of Master of Philosophy in History Cardiff University 2016 Summary This thesis concentrates on the economic integration of three principal German North Sea ports – Emden, Bremen and Hamburg – into the Bismarckian nation- state. Prior to the outbreak of the First World War, Emden, Hamburg and Bremen handled a major share of the German Empire’s total overseas trade. However, at the time of the foundation of the Kaiserreich, the cities’ roles within the Empire and the new German nation-state were not yet fully defined. Initially, Hamburg and Bremen insisted upon their traditional role as independent city-states and remained outside the Empire’s customs union. Emden, meanwhile, had welcomed outright annexation by Prussia in 1866. After centuries of economic stagnation, the city had great difficulties competing with Hamburg and Bremen and was hoping for Prussian support. This thesis examines how it was possible to integrate these port cities on an economic and on an underlying level of civic mentalities and local identities. Existing studies have often overlooked the importance that Bismarck attributed to the cultural or indeed the ideological re-alignment of Hamburg and Bremen. Therefore, this study will look at the way the people of Hamburg and Bremen traditionally defined their (liberal) identity and the way this changed during the 1870s and 1880s. It will also investigate the role of the acquisition of colonies during the process of Hamburg and Bremen’s accession. In Hamburg in particular, the agreement to join the customs union had a significant impact on the merchants’ stance on colonialism.

  • Shipping Made in Hamburg
    Shipping made in Hamburg The history of the Hapag-Lloyd AG THE HISTORY OF THE HAPAG-LLOYD AG Historical Context By the middle of the 19th Century the industrial revolution has caused the disap- pearance of many crafts in Europe, fewer and fewer workers are now required. In a first process of globalization transport links are developing at great speed. For the first time, railways are enabling even ordinary citizens to move their place of residen- ce, while the first steamships are being tested in overseas trades. A great wave of emigration to the United States is just starting. “Speak up! Why are you moving away?” asks the poet Ferdinand Freiligrath in the ballad “The emigrants” that became something of a hymn for a German national mo- vement. The answer is simple: Because they can no longer stand life at home. Until 1918, stress and political repression cause millions of Europeans, among them many Germans, especially, to make off for the New World to look for new opportunities, a new life. Germany is splintered into backward princedoms under absolute rule. Mass poverty prevails and the lower orders are emigrating in swarms. That suits the rulers only too well, since a ticket to America produces a solution to all social problems. Any troublemaker can be sent across the big pond. The residents of entire almshouses are collectively despatched on voyage. New York is soon complaining about hordes of German beggars. The dangers of emigration are just as unlimited as the hoped-for opportunities in the USA. Most of the emigrants are literally without any experience, have never left their place of birth, and before the paradise they dream of, comes a hell.

  • Sunopta to Demand Immediate Delisting from Berlin-Bremen Stock Exchange
    SunOpta to Demand Immediate Delisting from Berlin-Bremen Stock Exchange TORONTO--Aug. 5, 2004--SunOpta Inc. (SunOpta or the Company) (Nasdaq:STKL) (TSX:SOY) today announced that it is demanding an immediate delisting from the Berlin-Bremen Stock Exchange in an attempt to prevent trading practices that are banned in the United States. SunOpta recently learned that it was one of more than 200 companies added to the Berlin- Bremen Stock Exchange without its knowledge, consent or authorization. Media reports concerning other companies have indicated that some stock traders may attempt to use this exchange to manipulate stock prices. SunOpta's management has instructed its counsel to request the immediate removal of SunOpta's common stock from this exchange. "We have no interest in trading on any exchange on which we have not sought listing," said Jeremy N. Kendall, SunOpta's Chairman & Chief Executive Officer. SunOpta Inc. is an owner/operator of high-growth ethical businesses, focusing on integrated business models in the natural and organic food markets. For the last six consecutive years, SunOpta was included in Profit magazine's 'Profit 100' list of the 100 fastest growing companies in Canada. The company has three business units: the SunOpta Food Group, which specializes in sourcing, processing and distribution of natural and organic food products integrated from seed through packaged products; the Opta Minerals Group, a producer, distributor, and recycler of environmentally friendly industrial materials; and the StakeTech Steam Explosion Group that engineers and markets clean pulping systems using patented steam explosion technology. Each of these business units has proprietary products and services that give it a solid competitive advantage in its sector.
