Circular Economy: Applications for Water Remediation

by Maulin P. Shah, Suvendu Manna, and Papita Das

The reclamation of wastewater (and other essential materials) is among the major research areas for understanding the effects of implementing a circular economic model. The re-use and re-cycling of wastewater can greatly reduce the overall demand for freshwater for various industrial applications. Such concepts could potentially greatly reduce the overall water demands of our planet if implemented successfully. Circular Economy: Applications for Water Remediation will examine the current understanding of the circular economy in water remediation processes, its drawbacks, and relatively unexplored areas that require further research. This book:• Provides an overview of the processes available to extract value-added materials from wastewater, such as clean water, nutrients, and energy.• Explores the possibilities of re-using wastewater for agricultural uses.• Provides an overview of the current policies and regulations concerning the implementation of circular economy concepts in wastewater remediation.

Circular Economy: Assessment and Case Studies (Environmental Footprints and Eco-design of Products and Processes)

by Subramanian Senthilkannan Muthu

This book highlights the notion of Circular Economy under the umbrella of Sustainability because of the widespread momentum it is gaining. Today the whole world is certainly in emergent need of an alternative system to traditional economy which is linear, i.e. make, use and dispose to get rid-off the waste and very important to ensure continuous use of resources, which is possible by the advent of circular economy. A circular economy aims to utilize the resources in use for as long as possible, extract the maximum value from them during use, then recover and regenerate products and materials at the end of each service life vis-à-vis traditional linear model. This book discusses circular economy in terms of assessment with various case studies.

Circularity in Textiles (Textile Science and Clothing Technology)

by Yasir Nawab Sheraz Ahmad Syeda Rubab Batool Muzzamal Hussain

This book explains the basic principles of recycling and circularity in textiles. With the emergence of "quick fashion," textile manufacturing has expanded significantly over the past few decades. The importance of textiles to human society goes beyond their practical uses in providing warmth, protection, and comfort. Therefore, the usage and production of textiles are enhanced substantially compared to the past globally. As a result, rates of textile production and trash output have grown drastically. The other side of the story is the drastic rate at which they are dumped into landfills which is almost a garbage truck every second. If this alarming trend continues, there will be serious environmental consequences. It is well known that the textile sector is recognized as the second largest industrial polluter in the world, producing 20% of the global wastewater and accounting for 10% of carbon emissions. Additionally, harmful chemicals are utilized and emitted during the manufacture of textiles, which has an impact on ecosystems and public health The last 150 years of the textile industrial system fundamentally follow the "take-make-dispose" principle, in which resources are continuously taken out of a natural system (take), changed during production (make), and used for various purposes within the human system (use), and then released back into the environment (dispose of). In this way, manufacturing industries produce waste-producing commodities to make money, which eventually has a negative impact leading to the lack of resources resulting in price volatility, uncertainty, and economic crises. This book consists of 11 potential chapters to cover all the aspects of “circularity in textiles.”

Circulating Tumor Cells in Breast Cancer Metastatic Disease (Advances in Experimental Medicine and Biology #1220)

by Roberto Piñeiro

This book is aimed to summarise the key aspects of the role of circulating tumour cells (CTCs) in breast cancer, with special attention to their contribution to tumour progression and establishment of metastatic disease. We aim to give a clear overview of the knowledge about CTCs, framed in the context of breast cancer, by analysing basic and clinical research carried out so far. In a broader sense, we will address what are the main clinical needs of this disease based on its molecular heterogeneity (subtypes) and lay out the knowledge and understanding that CTCs are giving about it and how they are contributing and can still improve the better monitoring and management of breast cancer patients. We will discuss the evidences of the use of CTCs as a tool to monitor cancer progression and therapy response, based on the prognostic and predictive value they have, as well as a tool to unravel mechanisms of resistance to therapy and to identify new biomarkers allowing to predict therapy success. Moreover, we will analyse the main aspects of ongoing clinical trials and how they can contribute to determine the clinical utility of CTCs as a breast cancer biomarker. We will also touch upon general knowledge or basic notions of the biology of the metastatic process in epithelial cancers, in order to understand the origin and biology of CTCs. In this sense, we will pay special attention to EMT (epithelial to mesenchymal transition), dormancy and minimal residual disease, three key aspects that determine the outcome of the disease. We will also cover general aspects on the isolation and characterization techniques applies to the study of CTCs, and also the possibilities that the study of CTCs, as a biomarker with biological function, is opening in terms of understanding the biology of metastatic cells and the identification of therapeutic targets based on the functional and molecular characterization of CTCs. Lastly, we will try to foresee the future of CTCs in terms of clinical application and implementation in the clinical routine.

Cisterns: Sustainable Development, Architecture and Energy

by Ali Sayigh Alireza Dehghani-sanij

Cisterns: Sustainable Development, Architecture and Energy was written on beliefs that based on historical evidence and actual findings, Iran is most probably the country where cisterns, or Aub-anbars in Farsi, were first developed and built. Therefore, it is quite natural for the author to name cisterns in the text Aub-anbars, as it has been called for centuries in this country, the translation of the same name having been used in other countries too. Although in some books, journals and papers published out of Iran by foreign and Iranian scholars, the names Cistern or Water Reservoir have been used. The word Aub-anbar is a compound noun in Farsi; Aub means water and Anbar means tank/reservoir. Putting them together gives the noun Aub-anbarand it should be used as one word.People of the region wanting reserved cool water whether in cities or in different locations across the harsh desert during their travel. Queen Zubeida, the wife of Khalifa Haroon Al-Rasheed in 750 AD built one of these cistern closer to the town of Hiyal in Saudi Arabia so that the Pilgrims? Caravans going to Mecca will have cool, fresh water. This book consists of 11-chapters with full analysis, illustrations and photographs. It makes interesting readings to those interested into vernacular architecture, traditional buildings and creative thinking.

Cities and Complexity: Understanding Cities with Cellular Automata, Agent-Based Models, and Fractals

by Michael Batty

This is a crucial text for anyone interested in the interrelationships of media and design processes. As urban planning moves from a centralized, top-down approach to a decentralized, bottom-up perspective, our conception of urban systems is changing. In Cities and Complexity, Michael Batty offers a comprehensive view of urban dynamics in the context of complexity theory, presenting models that demonstrate how complexity theory can embrace a myriad of processes and elements that combine into organic wholes. He argues that bottom-up processes--in which the outcomes are always uncertain--can combine with new forms of geometry associated with fractal patterns and chaotic dynamics to provide theories that are applicable to highly complex systems such as cities. Batty begins with models based on cellular automata (CA), simulating urban dynamics through the local actions of automata. He then introduces agent-based models (ABM), in which agents are mobile and move between locations. These models relate to many scales, from the scale of the street to patterns and structure at the scale of the urban region. Finally, Batty develops applications of all these models to specific urban situations, discussing concepts of criticality, threshold, surprise, novelty, and phase transition in the context of spatial developments. Every theory and model presented in the book is developed through examples that range from the simplified and hypothetical to the actual. Deploying extensive visual, mathematical, and textual material, Cities and Complexity will be read both by urban researchers and by complexity theorists with an interest in new kinds of computational models.

Citizens and Nation

by Gerald Friesen

Grandmother Andre told stories in front of a campfire. Elizabeth Goudie wrote a memoir in school scribblers. Phyllis Knight taped hours of interviews with her son. Today's families rely on television and video cameras. They are all making history.In a different approach to that old issue, 'the Canadian identity,' Gerald Friesen links the media studies of Harold Innis to the social history of recent decades. The result is a framework for Canadian history as told by ordinary people. Friesen suggests that the common peoples' perceptions of time and space in what is now Canada changed with innovations in the dominant means of communication. He defines four communication-based epochs in Canadian history: the oral-traditional world of pre-contact Aboriginal people; the textual-settler household of immigrants; the print-capitalism of the nineteenth and twentieth centuries; and the screen-capitalism that has emerged in the last few decades. This analysis of communication is linked to distinctive political economies, each of which incorporates its predecessors in an increasingly complex social order.In each epoch, using the new communication technologies, people struggled to find the political means by which they could ensure that they and their households survived and, if they were lucky, prospered. Canada is the sum of their endeavours. "Citizens and Nation" demonstrates that it is possible to find meaning in the nation's past that will interest, among others, a new, young, and multicultural reading audience.

Citizens of Worlds: Open-Air Toolkits for Environmental Struggle

by Jennifer Gabrys

An unparalleled how-to guide to citizen-sensing practices that monitor air pollution Modern environments are awash with pollutants churning through the air, from toxic gases and intensifying carbon to carcinogenic particles and novel viruses. The effects on our bodies and our planet are perilous. Citizens of Worlds is the first thorough study of the increasingly widespread use of digital technologies to monitor and respond to air pollution. It presents practice-based research on working with communities and making sensor toolkits to detect pollution while examining the political subjects, relations, and worlds these technologies generate. Drawing on data from the Citizen Sense research group, which worked with communities in the United States and the United Kingdom to develop digital-sensor toolkits, Jennifer Gabrys argues that citizen-oriented technologies promise positive change but then collide with entrenched and inequitable power structures. She asks: Who or what constitutes a &“citizen&” in citizen sensing? How do digital sensing technologies enable or constrain environmental citizenship? Spanning three project areas, this study describes collaborations to monitor air pollution from fracking infrastructure, to document emissions in urban environments, and to create air-quality gardens. As these projects show, how people respond to, care for, and struggle to transform environmental conditions informs the political subjects and collectives they become as they strive for more breathable worlds.
