Post-Tensioning in Building Construction
by Bijan O. AalamiWorldwide growth and application of post-tensioning in recent years is one of the major developments in building construction. The growth is propelled by a burgeoning demand for construction of serviceable and safe buildings. Unlike traditional construction, post-tensioning is based on new design methodology often not covered in traditional engineering courses. With more than 40 years of experience of study, teaching and work on post-tensioning applications around the world, the author has written this book for students as well as practicing engineers, contractors and academics. While the book covers the basics and concepts of post-tensioning in simple and clear language, it also focuses on the application and detailed design through real world examples. Topics of the book include the European and the American building Codes for post-tensioning design. The codes are detailed in the book’s examples such as column-supported floors and beam frames. The book explains and highlights the importance of shortening specific to post-tensioned members and construction detailing for serviceable and safe performance.

Post-Truth Imaginations: New Starting Points for Critique of Politics and Technoscience (History and Philosophy of Technoscience)
by Kjetil RommetveitThis book engages with post-truth as a problem of societal order and for scholarly analysis. It claims that post-truth discourse is more deeply entangled with main Western imaginations of knowledge societies than commonly recognised. Scholarly responses to post-truth have not fully addressed these entanglements, treating them either as something to be morally condemned or as accusations against which scholars have to defend themselves (for having somehow contributed to it). Aiming for wider problematisations, the authors of this book use post-truth to open scholarly and societal assumptions to critical scrutiny. Contributions are both conceptual and empirical, dealing with topics such as: the role of truth in public; deep penetrations of ICTs into main societal institutions; the politics of time in neoliberalism; shifting boundaries between fact – value, politics – science, nature – culture; and the importance of critique for public truth-telling. Case studies range from the politics of nuclear power and election meddling in the UK, over smart technologies and techno-regulation in Europe, to renewables in Australia. The book ends where the Corona story begins: as intensifications of Modernity’s complex dynamics, requiring new starting points for critique.

Postcolonial Developments: Agriculture in the Making of Modern India
by Akhil GuptaThis definitive study brings together recent critiques of development and work in postcolonial studies to explore what the postcolonial condition has meant to rural people in the Third World. Focusing on local-level agricultural practices in India since the "green revolution" of the 1960s, Akhil Gupta challenges the dichotomy of "developed" and "underdeveloped," as well as the notion of a monolithic postcolonial condition. In so doing, he advances discussions of modernity in the Third World and offers a new model for future ethnographic scholarship. Based on fieldwork done in the village of Alipur in rural north India from the early 1980s through the 1990s, Postcolonial Developments examines development itself as a post-World War II sociopolitical ideological formation, critiques related policies, and explores the various uses of the concept of the "indigenous" in several discursive contexts. Gupta begins with an analysis of the connections and conflicts between the world food economy, transnational capital, and technological innovations in wheat production. He then examines narratives of village politics in Alipur to show how certain discourses influenced governmental policies on the green revolution. Drawing links between village life, national trends, and global forces, Gupta concludes with a discussion of the implications of environmentalism as exemplified by the Rio Earth Summit and an examination of how global environmental treaties may detrimentally affect the lives of subaltern peoples. With a series of subtle observations on rural politics, nationalism, gender, modernization, and difference, this innovative study capitalizes on many different disciplines: anthropology, sociology, comparative politics, cultural geography, ecology, political science, agricultural economics, and history.
Postdigital Aesthetics
by David M. Berry Michael DieterPostdigital Aesthetics presents a constellation of contributors who seek to unpack, explore and critically reflect on the questions raised by the notion of the postdigital and its relation to our computational everyday lives. Through a number of interventions, each chapter subjects the concept and ideas that surround our ideas of an aesthetic of the postdigital to critical examination to understand the new asterism of material digital culture in the twenty-first century. From Minecraft to post-internet art, each contributor offers an original perspective on network culture and its distinctive aesthetics and politics, and the relations between art, computation and design.

Postdigital Storytelling: Poetics, Praxis, Research (Digital Research in the Arts and Humanities)
by Spencer JordanPostdigital Storytelling offers a groundbreaking re-evaluation of one of the most dynamic and innovative areas of creativity today: digital storytelling. Central to this reassessment is the emergence of metamodernism as our dominant cultural condition. This volume argues that metamodernism has brought with it a new kind of creative modality in which the divide between the digital and non-digital is no longer binary and oppositional. Jordan explores the emerging poetics of this inherently transmedial and hybridic postdigital condition through a detailed analysis of hypertextual, locative mobile and collaborative storytelling. With a focus on twenty-first century storytelling, including print-based and nondigital art forms, the book ultimately widens our understanding of the modes and forms of metamodernist creativity. Postdigital Storytelling is of value to anyone engaged in creative writing within the arts and humanities. This includes scholars, students and practitioners of both physical and digital texts as well as those engaged in interdisciplinary practice-based research in which storytelling remains a primary approach.

Postharvest Nanotechnology for Fresh Horticultural Produce: Innovations and Applications (Innovations in Postharvest Technology Series)
by Radhakrishnan E. K. Ashitha Jose Sunil PareekFood scarcity and insecurity is an alarming issue throughout the world. Postharvest loss due to both mechanical damage and microbial spoilage significantly influences the shelf life and hence the availability of agricultural produce. Once initiated, the microbial spoilage can make bulk quantity of a given agricultural product unacceptable for human consumption, and several methods have already been used to try to manage this. Considering the limited success of the available methods, there is increasing interest in exploring nanotechnological methods. These methods are being considered for both the development of various platforms for antimicrobial/barrier packaging applications that minimize the contact of agricultural produce with the external environment, and also for design sensors to ensure food safety and quality. The impact of various nano-systems developed through material engineering on the shelf-life enhancement and storage of fresh horticultural produce will have revolutionary effects on post-harvest management in the coming years. Hence, Postharvest Nanotechnology for Fresh Horticultural Produce has been edited to advance understanding of material development, intelligent selection of nanomaterials to ensure the nontoxic nature, and future perspectives of nanotechnology on postharvest produce. This includes various types of nanoparticles exploited for the postharvest management, their mechanism of action, varied applications and material engineering, along with natural products including essential oils and plant bioactives, modelling of various tailor-made materials to meet the required properties of the packed food, advancements in the nanotechnological applications for the minimally processed food, and the toxicity concerns.
