Acknowledging Indigenous Knowledge: Voices of Tropical Forest People (Urbanization, Industrialization, and the Environment)
by Purabi BoseThis book explores how the landscapes in indigenous territories are rapidly changing due to increased global industrial demand. This deforestation and urbanization have isolated the indigenous people from practicing ‘traditional ways of life.’ Portrayed in this book is the indigenous people’s perspective of their indigenous knowledge (IK) about the environment and why losing IK is a threat to humans, wildlife, and nature. Insight is shared into why acknowledging IK as a science can help solve climate change, food and nutrition insecurity, and increasing new types of pandemics through evidence‑based stories from indigenous people. Features:• Bridges the fractured space between science and nature.• Documents the perspectives of indigenous peoples about their ancestral knowledge.• Provides ethnographic qualitative comparative case studies of forest‑dwelling indigenous peoples over a 19‑year period.• Covers largely remote indigenous territories of ten tropical countries in the Global South.• Provides evidence‑based stories examining indigenous knowledge’s role in the tropics in preserving diverse landscapes and providing nature‑based solutions.
Acoustic Analysis and Design of Short Elliptical End-Chamber Mufflers
by Akhilesh MimaniThis book presents a three-dimensional analysis of acoustic wave propagation in an elliptical waveguide, and applies the equations and concepts to design axially short elliptical end-chamber muffler configurations which are an important component of a complex multi-pass muffler used in a modern-day automotive exhaust system. A general solution of the Helmholtz equation in elliptical cylindrical co-ordinates is presented in terms of the Mathieu and modified Mathieu modal functions. This is followed by the tabulation and analysis, for the first time, of the non-dimensional resonance frequencies of the transverse modes of a rigid-wall elliptical waveguide for a complete range of aspect ratio. The modal shape patterns of the first few circumferential, radial and cross-modes are examined with particular attention to the pressure nodal ellipses and hyperbolae. An analytical formulation is then outlined for characterizing a single-inlet and single-outlet elliptical muffler with the inlet located on the end face and the outlet located either on the end face or side-surface. The ensuing chapter is devoted toward analyzing the Transmission Loss (TL) performance of different short end-chamber mufflers, namely (a) the straight-flow configuration having ports located on the opposite face, (b) the flow-reversal configuration with ports located on the same end face and (c) configuration with inlet port on the end face and outlet on the side surface. Design guidelines are formulated in terms of the optimal location of inlet and outlet ports which suppresses the deteriorating influence of certain higher-order modes, thereby delivering a broadband TL performance. Directions for future work are discussed toward the end. In summary, this book is a one-stop solution for a practicing automotive engineer designing mufflers, for an applied mathematician studying wave propagation in elliptical geometries, and also as a niche area within noise control engineering.

Acoustic Investigation of Complex Seabeds (SpringerBriefs in Oceanography)
by Jacques Yves Guigné Philippe BlondelOffshore drilling and constructions require exact knowledge of the geophysical properties of the seabed and sub-seabed, as unexpected objects can slow down or halt projects. This book presents the state-of-the-art in acoustic exploration of the seabed and sub-seabed, from initial designs in the 1980s to commercial contracting and operation of the Acoustic Corer(tm) in the last decade. The Acoustic Corer(tm) is a high-definition commercial acoustic sub-bottom imaging system, producing an "acoustic core" within which sub-seabed sedimentary characteristics and discrete buried objects larger than 0. 5 m can be identified and mapped. It makes use of the innovative JYG-cross design, inspired by seismic reflection and uses Synthetic Aperture Sonar (SAS) multi-angle scattering in and within the seabed to deliver unprecedented imagery. This book was written by the inventor of these concepts, a known specialist in seabed acoustics, with help from an experienced academic and author. It is intended first and foremost as a "how-to" guide for offshore industries looking at techniques to make the installation of different types of structures safe and efficient.
Acoustic Waves in Periodic Structures, Metamaterials, and Porous Media: From Fundamentals to Industrial Applications (Topics in Applied Physics #143)
by Noé Jiménez Olga Umnova Jean-Philippe GrobyThis book delivers a comprehensive and up-to-date treatment of practical applications of metamaterials, structured media, and conventional porous materials. With increasing levels of urbanization, a growing demand for motorized transport, and inefficient urban planning, environmental noise exposure is rapidly becoming a pressing societal and health concern. Phononic and sonic crystals, acoustic metamaterials, and metasurfaces can revolutionize noise and vibration control and, in many cases, replace traditional porous materials for these applications.In this collection of contributed chapters, a group of international researchers reviews the essentials of acoustic wave propagation in metamaterials and porous absorbers with viscothermal losses, as well as the most recent advances in the design of acoustic metamaterial absorbers. The book features a detailed theoretical introduction describing commonly used modelling techniques such as plane wave expansion, multiple scattering theory, and the transfer matrix method. The following chapters give a detailed consideration of acoustic wave propagation in viscothermal fluids and porous media, and the extension of this theory to non-local models for fluid saturated metamaterials, along with a description of the relevant numerical methods. Finally, the book reviews a range of practical industrial applications, making it especially attractive as a white book targeted at the building, automotive, and aeronautic industries.

Across the Great Divide: Explorations In Collaborative Conservation And The American West
by Daniel Kemmis Sarah F. Bates Philip Brick Donald SnowAmid the policy gridlock that characterizes most environmental debates, a new conservation movement has emerged. Known as "collaborative conservation," it emphasizes local participation, sustainability, and inclusion of the disempowered, and focuses on voluntary compliance and consent rather than legal and regulatory enforcement. Encompassing a wide range of local partnerships and initiatives, it is changing the face of resource management throughout the western United States.Across the Great Divide presents a thoughtful exploration of this new movement, bringing together writing, reporting, and analysis of collaborative conservation from those directly involved in developing and implementing the approach. Contributors examine: the failure of traditional policy approaches recent economic and demographic changes that serve as a backdrop for the emergence of the movement the merits of, and drawbacks to, collaborative decision-making the challenges involved with integrating diverse voices and bringing all sectors of society into the movement .In addition, the book offers in-depth stories of eight noteworthy collaborative initiatives -- including the Quincy Library Group, Montana's Clark Fork River, the Applegate Partnership, and the Malpai Borderlands -- that explore how different groups have organized and acted to implement their goals.Among the contributors are Ed Marston, George Cameron Coggins, David Getches, Andy Stahl, Maria Varela, Luther Propst, Shirley Solomon, William Riebsame, Cassandra Moseley, Lynn Jungwirth, and others. Across the Great Divide is an important work for anyone involved with collaborative conservation or the larger environmental movement, and for all those who care about the future of resource management in the West.

Acting with the World: Agency in the Anthropocene
by Andrew PickeringIn the Anthropocene our actions are coming home to roost. Global warming, species extinctions, and environmental disasters are the dark side of our mastery of nature. In Acting with the World, Andrew Pickering identifies a different pattern of being and doing that can evade this dark side, a pattern that he calls acting-with the world. In contrast to our usual practice of acting on the world, acting-with foregrounds nonhuman or more-than-human agency and aims to attune our practices to the propensities of nature. Pickering explores examples of acting-with from around the globe, including flood control on the Mississippi River, ecosystem restoration on the Colorado River, the Room for the River project and rewilding in the Netherlands, natural farming in Japan, Aboriginal fire techniques in Australia, and Amazonian shamanism. Pickering argues that acting-with intimately and gracefully plugs us into nature, undercuts the Anthropocene from below, and offers a constructive approach to addressing otherwise intractable wicked problems.
