Over the past 25 years, artists have vigorously engaged the debate around globalization, examining cross-border exchange from mass migration to the dynamics of translation, and devising new conceptual categories and new formal and metaphorical resources along the way. Noted art critic Marcus Verhagens timely examination of artistic interventions, Flows and Counterflows tells the story of projects that draw out both the dangers and tangible benefits of global exchange. In seven thought-provoking illustrated essays Verhagen maps the global art worlds shifting terrain and offers an incisive and original account of contemporary arts relationship to the processes of globalisation. The softcover survey covers how art addresses global markers such as tourism and border control; how the art system itself has been reshaped; and how artists resist by building informal networks. Packed with clearly explained and illustrated contemporary artworks, it is an indispensable history of art for our current times. Verhagen teaches in the United States and Europe and has published extensively in LeftReview, Art Monthly, Frieze along with many other publications.

This book discusses the physical mechanisms that drive counterflows, examining how they emerge, develop, become double and multiple counterflows and comprise both global and local circulations. Counterflows play an important role in nature and technology. A natural example is the Gulf Stream and the opposite flow in the ocean depths. Technological applications include hydrocyclones, vortex tubes and vortex combustors. These elongated counterflows are wildly turbulent but survive intense mixing, a seeming paradox. Local counterflows, whose spatial extent is small compared with that of surrounding flows, occur behind bluff bodies and in swirling streams. The latter are often referred to as vortex breakdown bubbles, which occur in tornadoes and above delta wings. Most scale counterflows are cosmic bipolar jets. Most miniature counterflows occur in capillary menisci of electrosprays and fuel atomisers.

Media on the Move provides a critical analysis of the dynamics of the international flow of images and ideas. This comes at a time when the political, economic and technological contexts within which media organisations operate are becoming increasingly global. The surge in transnational traffic in media products has primarily benefited the major corporations such as Disney, AOL, Time Warner and News Corporation. However, as this book argues, new networks have emerged which buck this trend: Brazilian TV is watched in China, Indian films have a huge following in the Arab world and Al Jazeera has become a household name in the West. Combining a theoretical perspective on contra-flow of media with grounded case studies into one up-to-date and accessible volume, Media on the Move provides a much-needed guide to the globalization of media, going beyond the standard Anglo-American view of this evolving phenomenon.

Porous and Complex Flow Structures in Modern Technologies represents a new approach to the field, considering the fundamentals of porous media in terms of the key roles played by these materials in modern technology. Intended as a text for advanced undergraduates and as a reference for practicing engineers, the book uses the physics of flows in porous materials to tie together a wide variety of important issues from such fields as biomedical engineering, energy conversion, civil engineering, electronics, chemical engineering, and environmental engineering. Thus, for example, flows of water and oil through porous ground play a central role in energy exploration and recovery (oil wells, geothermal fluids), energy conversion (effluents from refineries and power plants), and environmental engineering (leachates from waste repositories). Similarly, the demands of miniaturization in electronics and in biomedical applications are driving research into the flow of heat and fluids through small-scale porous media (heat exchangers, filters, gas exchangers). Filters, catalytic converters, the drying of stored grains, and a myriad of other applications involve flows through porous media. By providing a unified theoretical framework that includes not only the traditional homogeneous and isotropic media but also models in which the assumptions of representative elemental volumes or global thermal equilibrium fail, the book provides practicing engineers the tools they need to analyze complex situations that arise in practice. This volume includes examples, solved problems and an extensive glossary of symbols.

This book discusses flow cells, their emergence, multiplication, coalescence, disappearance, and physical reasons for their metamorphoses.
