Gaseous Detonation Physics and Its Universal Framework Theory (Shock Wave and High Pressure Phenomena)
by Zonglin Jiang Honghui TengThis book highlights the theories and research progress in gaseous detonation research, and proposes a universal framework theory that overcomes the current research limitations. Gaseous detonation is an extremely fast type of combustion that propagates at supersonic speed in premixed combustible gas. Being self-sustaining and self-organizing with the unique nature of pressure gaining, gaseous detonation and its gas dynamics has been an interdisciplinary frontier for decades. The research of detonation enjoyed its early success from the development of the CJ theory and ZND modeling, but phenomenon is far from being understood quantitatively, and the development of theories to predict the three-dimensional cellular structure remains a formidable task, being essentially a problem in high-speed compressible reacting flow. This theory proposed by the authors’ research group breaks down the limitation of the one-dimensional steady flow hypothesis of the early theories, successfully correlating the propagation and initiation processes of gaseous detonation, and realizing the unified expression of the three-dimensional structure of cell detonation. The book and the proposed open framework is of high value for researchers in conventional applications such as coal mine explosions and chemical plant accidents, and state-of-the-art research fields such as supernova explosion, new aerospace propulsion engines, and detonation-driven hypersonic testing facilities. It is also a driving force for future research of detonation.

Gasotransmitters Signaling in Plants under Challenging Environment (Plant in Challenging Environments #5)
by Tariq Aftab Francisco J. CorpasAbiotic stressors, such as drought, extreme temperatures, heavy metals, or high salinity, are causing huge crop losses worldwide. These abiotic stressors are expected to become more extreme, less predictable, and more widespread in the near future. The harm of abiotic stresses includes the disruption of cellular redox homeostasis, reactive oxygen species (ROS) production, and oxidative stress in the plant. Plants have different mechanisms to fight stress, and these mechanisms are responsible for maintaining the required homeostasis in plants. Research on gasotransmitters is rapidly expanding and knowledge regarding the potential of gasotransmitters in biology and medicine is accumulating. Over the past few decades, the roles of these signaling molecules, especially NO and H2S, have been extensively studied for their application in plants. Recently, the emissions of endogenous gasotransmitters in plants have been widely studied and analyzed, thereby providing information to facilitate our understanding of new gasotransmitters signaling pathways. Given the multidimensional role of these signaling molecules, research over the past decades in mitigating abiotic stresses in plant biology and from an agriculture point of view, we intend to bring forth a comprehensive volume “Gasotransmitters Signaling in Plants under Challenging Environment". We are hopeful that this comprehensive volume will furnish the requisite of all those who are working or have an interest in the proposed topic

Gastrophysics: The New Science of Eating
by Charles SpenceThe science behind a good meal: all the sounds, sights, and tastes that make us like what we're eating—and want to eat more.Why do we consume 35 percent more food when eating with one other person, and 75 percent more when dining with three? How do we explain the fact that people who like strong coffee drink more of it under bright lighting? And why does green ketchup just not work? The answer is gastrophysics, the new area of sensory science pioneered by Oxford professor Charles Spence. Now he's stepping out of his lab to lift the lid on the entire eating experience—how the taste, the aroma, and our overall enjoyment of food are influenced by all of our senses, as well as by our mood and expectations. The pleasures of food lie mostly in the mind, not in the mouth. Get that straight and you can start to understand what really makes food enjoyable, stimulating, and, most important, memorable. Spence reveals in amusing detail the importance of all the “off the plate” elements of a meal: the weight of cutlery, the color of the plate, the background music, and much more. Whether we’re dining alone or at a dinner party, on a plane or in front of the TV, he reveals how to understand what we’re tasting and influence what others experience. This is accessible science at its best, fascinating to anyone in possession of an appetite. Crammed with discoveries about our everyday sensory lives, Gastrophysics is a book guaranteed to make you look at your plate in a whole new way.

Gated Communities and the Digital Polis: Rethinking Subjectivity, Reality, Exclusion, and Cooperation in an Urban Future (Advances in 21st Century Human Settlements)
by Kon Kim Heewon ChungThis edited collection provides an alternative discourse on cities evolving with physically and virtually networked communities—the ‘digital polis’—and offers a variety of perspectives from the humanities, media studies, geography, architecture, and urban studies. As an emergent concept that encompasses research and practice, the digital polis is oriented toward a counter-mapping of the digital cityscape beyond policing and gatekeeping in physical and virtual gated communities. Considering the digital polis as offering potential for active support of socially just and politically inclusive urban circumstances in ways that mirror the Greek polis, our attention is drawn towards the interweaving of the development of digital technology, urban space, and social dynamics. The four parts of this book address the formation of technosocial subjectivity, real-and-virtual combined urbanity, the spatial dimensions of digital exclusion and inclusion, and the prospect of emancipatory and empowering digital citizens. Individual chapters cover varied topics on digital feminism, data activism, networked individualism, digital commons, real-virtual communalism, the post-family imagination, digital fortress cities, rights to the smart city, online foodscapes, and open-source urbanism across the globe. Contributors explore the following questions: what developments can be found over recent decades in both physical and virtual communities such as cyberspace, and what will our urban future be like? What is the ‘digital polis’ and what kinds of new subjectivity does it produce? How does digital technology, as well as its virtuality, reshape the city and our spatial awareness of it? What kinds of exclusion and cooperation are at work in communities and spaces in the digital age? Each chapter responds to these questions in its own way, navigating readers through routes toward the digital polis.Chapter "Introduction - The digital polis and its practices: Beyond gated communities" is available open access under a Creative Commons Attribution 4.0 International License via link.springer.com.
