An examination of the central role of water politics and engineering in Spain's modernization, illustrating water's part in forging, maintaining, and transforming social power. In this book, Erik Swyngedouw explores how water becomes part of the tumultuous processes of modernization and development. Using the experience of Spain as a lens to view the interplay of modernity and environmental transformation, Swyngedouw shows that every political project is also an environmental project. In 1898, Spain lost its last overseas colony, triggering a period of post-imperialist turmoil still referred to as El Disastre. Turning inward, the nation embarked on “regeneration” and modernization. Water played a central role in this; during a turbulent period from the twentieth century into the twenty-first—through the Franco years and into the new era of liberal democracy—Spain's waterscapes were completely transformed, with large-scale projects that ranged from dam construction to irrigation to desalinization. Swyngedouw describes the contested political-ecological process that marked this transformation, showing that the Spain's diverse and contested paths to modernization were predicated on particular trajectories of environmental transformation. After laying out his theoretical perspectives, Swyngedouw analyzes three periods of Spain's political-ecological modernization: the aspirations and stalled modernization of the early twentieth century; the accelerated efforts under the authoritarian Franco regime—which included six hundred dams, expanded hydroelectricity, and massive irrigation; and the changing hydro-social landscape under social democracy. Offering an innovative perspective on the relationship of nature and society, Liquid Power illuminates the political nature of nature.

Open Circuits is a photographic exploration of the beautiful design inside everyday electronics. Its stunning cross-section photography unlocks a hidden world full of elegance, subtle complexity, and wonder. Our phones, computers, and appliances are made of hundreds of internal components, each precisely engineered to perform a certain function, but none intended to actually be seen. Through painstakingly executed, vividly detailed cross-section photography, Open Circuits reveals the surprising—and often accidental—beauty hiding inside the electronic components that drive our everyday devices. From resistors to LEDs, USB cables to headphone jacks, stepper motors to nixie tubes, the book’s arresting imagery transforms more than 130 components into delightful works of art. As you visually dissect the components’ insides, you’ll learn about how they work and how they were made. Open Circuits has something for everyone to appreciate, whether you’re a seasoned electrical engineer, an amateur tinkerer, or simply a lover of art and photography.

Traditionally heat and light are thought as energy sources to drive a particular chemical reaction, but now ultrasound is a promising energy source for this purpose. The collapse of a bubble generates a wide range of high temperatures and pressures, and therefore, use of ultrasound has a considerable potential in chemical and allied sciences. Ultrasound-assisted reactions are green and economically viable alternatives to conventional techniques. This new volume presents a complete picture of ultrasound-assisted reactions and technologies that can be used in organic synthesis, polymer synthesis and degradation, nanomaterials, wastewater treatment, food ingredients and products, pharmaceutical applications, bioenergy applications, and more. This volume aims to shed light on the diversified applications of ultrasound and its significant role as a green chemical pathway. Sonochemistry deals with the effect of ultrasonic waves on chemical systems. It has green value because of non-hazardous acoustic radiation and is therefore duly recognized as a green chemistry by synthetic chemists as well as environmentalists. There is no direct interaction of ultrasound with molecular species, but the observed chemical and physical effects of ultrasound are due to the cavitational collapse, which produces drastic conditions of temperature and pressure locally. It induces the formation of various chemical species, which cannot be easily attained under conventional conditions. Sometimes, these species are responsible for driving towards an unusual reactivity in molecular entities. This book, Sonochemistry: An Emerging Green Technology, provides the complete development of sonochemistry, starting with an introduction and basic concepts of sonochemistry and proceeding on to different types of sonochemical reactions, instrumentation, use of ultrasound in driving particular chemical reactions, and its applications in various fields, such as polymer synthesis, decontamination of water and wastewater, preparation of nanomaterials, food technology, pharmaceutical sciences, etc. The book also briefly discusses some areas that utilize ultrasounds of different frequencies. These include food products and their processing; anaerobic digestion of waste; and medical applications such as ultrasonography, sonodynamic therapy, drug delivery, etc. Sonochemistry will be successfully used on an industrial scale in pharmaceutical drugs, polymers, nanomaterials, food technology, material science, biogas production, etc. in years to come and will be an established green chemical technology of the future.
