Flows And Counterflows

"The last 15 years have seen radical shifts in the roles of the various players in the Dutch housing sector. In particular, the privatization of Dutch housing corporations in 1994 has translated into a new dynamic in processes of urban renewal. At present this is most evident in the tackling of so-called problem neighbourhoods, where the policy of the parties involved is increasingly focused on reducing the number of rented properties in the social sector while increasing the number of owner-occupied properties for medium- and upper-income brackets. The process of transforming a neighbourhood previously inhabited by people from the lower social strata into a residential area for the middle classes is termed 'gentrification'. Initially, this was a bottom-up process and was often driven by the 'creative class', as seen in run-down parts of London and New York, but this mechanism has now been discovered by the market. The creative industries and cultural facilities are now being used as a top-down instrument to kick-start this process. OASE 73 explores the theoretical background to the phenomenon of 'gentrification' from various perspectives, such as the visual arts, cultural history, economics, landscape and urban design, and sociology. This issue also includes case studies on London, Amsterdam, Rotterdam, Antwerp and Vienna."--Publisher's web page for this issue, https://www.oasejournal.nl/en/Issues/73

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.

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

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.

In Queer Chinese Cultures and Mobilities, John Wei brings light to the germination and movements of queer cultures and social practices in today’s China and Sinophone Asia. While many scholars attribute China’s emergent queer cultures to the neoliberal turn and the global political landscape, Wei refuses to take these assumptions for granted. He finds that the values and pitfalls of the development-induced mobilities and post-development syndromes have conjointly structured and sustained people’s ongoing longings and sufferings under the dual pressure of compulsory familism and compulsory development. While young gay men are increasingly mobilized in their decision-making to pursue sociocultural and socioeconomic capital to afford a queer life, the ubiquitous and compulsory mobilities have significantly reshaped and redefined today’s queer kinship structure, transnational cultural network, and social stratification in China and capitalist Asia. With Queer Chinese Cultures and Mobilities, Wei interrogates the meanings and functions of mobilities at the forefront of China’s internal transformation and international expansion for its great dream of revival, when gender and sexuality have become increasingly mobilized with geographical, cultural, and social class migrations and mobilizations beyond traditional and conventional frameworks, categories, and boundaries. “This timely and compelling contribution to Chinese/Sinophone studies and queer/sexuality studies is a pleasure to read. John Wei explores a diverse, fascinating, and unevenly explored archive of queer materials, deftly deploying scholarship in multiple fields to analyze the emergent formation of queer Sinophone cultures.” —David L. Eng, University of Pennsylvania “John Wei’s meticulously researched and rigorously argued new book sets a new standard for queer Chinese studies. Bringing together a dazzling array of ethnographic materials, films, and digital media, Wei proposes the concept of stretched kinship to show us how questions of sexuality are always questions of mobilities as queer migrants become ineluctably entangled with China’s compulsory familism and developmentalism.” —Petrus Liu, Boston University
