Tunnels
by Roderick Gordon Brian Williams14-year-old Will Burrows has little in common with his strange, dysfunctional family. In fact, the only bond he shares with his eccentric father is a passion for archaeological excavation. So when Dad mysteriously vanishes, Will is compelled to dig up the truth behind his disappearance. He unearths the unbelievable: a secret subterranean society. "The Colony" has existed unchanged for a century, but it's no benign time capsule of a bygone era--because the Colony is ruled by a cultlike overclass, the Styx. Before long--before he can find his father--Will is their prisoner....
Tunnels and Underground Cities. Engineering and Innovation Meet Archaeology, Architecture and Art: Proceedings of the WTC 2019 ITA-AITES World Tunnel Congress (WTC 2019), May 3-9, 2019, Naples, Italy (Proceedings in Earth and Geosciences)
by Daniele Peila Giulia Viggiani Tarcisio CelestinoTunnels and Underground Cities: Engineering and Innovation meet Archaeology, Architecture and Art contains the contributions presented at the World Tunnel Congress 2019 (Naples, Italy, 3-9 May 2019). The use of underground space is continuing to grow, due to global urbanization, public demand for efficient transportation, and energy saving, production and distribution. The growing need for space at ground level, along with its continuous value increase and the challenges of energy saving and achieving sustainable development objectives, demand greater and better use of the underground space to ensure that it supports sustainable, resilient and more liveable cities. This vision was the source of inspiration for the design of the logos of both the International (ITA) and Italian (SIG) Tunnelling Association. By placing key infrastructures underground – the black circle in the logos – it will be possible to preserve and enhance the quality of the space at ground level – the green line. In order to consider and value underground space usage together with human and social needs, engineers, architects, and artists will have to learn to collaborate and develop an interdisciplinary design approach that addresses functionality, safety, aesthetics and quality of life, and adaptability to future and varied functions. The 700 contributions cover a wide range of topics, from more traditional subjects connected to technical challenges of design and construction of underground works, with emphasis on innovation in tunneling engineering, to less conventional and archetypically Italian themes such as archaeology, architecture, and art. The book has the following main themes: Archaeology, Architecture and Art in underground construction; Environment sustainability in underground construction; Geological and geotechnical knowledge and requirements for project implementation; Ground improvement in underground constructions; Innovation in underground engineering, materials and equipment; Long and deep tunnels; Public communication and awareness; Risk management, contracts and financial aspects; Safety in underground construction; Strategic use of underground space for resilient cities; Urban tunnels. Tunnels and Underground Cities: Engineering and Innovation meet Archaeology, Architecture and Art is a valuable reference text for tunneling specialists, owners, engineers, architects and others involved in underground planning, design and building around the world, and for academics who are interested in underground constructions and geotechnics.

Turbulence in Open Channels and River Flows
by Michio SanjouThis book is a monograph on the open-channel turbulence. Former part covers the basic characteristics including derivation of governing equations. The latter part focuses on various topics related to environmental management and disaster problem in river turbulence. The turbulent flow is a momentary phenomenon, but there are also organized motions, not just random. How to feedback this fundamental knowledge to the practice of hydraulic engineering including mass and sediment transport is a big issue. This book explains in detail the basic points and various specific problems of river turbulence in order for abecedarians to easily learn for themselves. By including application examples, the understanding of readers is more deepened. In addition, it also outlines the methods of hydraulics experiments and turbulence measurements. So, it will be very useful for readers themselves to measure turbulence with their own hands in future. It is intended for a wide range of readers, from students studying hydraulics to graduate students who want to know more about the essence of phenomena, and engineers using it as a reference for hydraulic works and practice.

The Turbulence Problem: A Persistent Riddle in Historical Perspective (SpringerBriefs in History of Science and Technology)
by Michael EckertOn the road toward a history of turbulence, this book focuses on what the actors in this research field have identified as the “turbulence problem”. Turbulent flow rose to prominence as one of the most persistent challenges in science. At different times and in different social and disciplinary settings, the nature of this problem has changed in response to changing research agendas. This book does not seek to provide a comprehensive account, but instead an exemplary exposition on the environments in which problems become the subjects of research agendas, with particular emphasis on the first half of the 20th century.
Turbulence—an Odyssey: Origins and Evolution of a Research Field at the Interface of Science and Engineering (History of Physics)
by Michael EckertTurbulence is a research field where high expectations have met with recurrent frustration. It is a common perception among physicists, mathematicians and engineers that there is a "big mystery" behind the phenomenon of turbulence. Its history has also remained anything but well researched. Unlike topics such as quantum theory, which began to attract physics historians as long as fifty years ago, turbulence has - until now - received only little professional historical investigation. In this book, which complements his earlier SpringerBrief "The Turbulence Problem", the author sketches the history of turbulence from the vantage point of its roots (Part I), the basic concepts (Part II) and the formation of a scientific community that regarded turbulence as a research field in its own right (Part III). From this perspective turbulence research appears to undertake an odyssey through uncharted territories. The book follows this development up until a conference in Marseille in the year 1961, which marked the inauguration of turbulence in the words of its organizer as “a new science”. The epilogue contains some observations about turbulence research since 1961. This book provides a rich source of information for all those interested in the history of this major field of basic and applied science.
Turbulent Cascades II: Proceedings of the Euromech-ERCOFTAC Colloquium 589 (ERCOFTAC Series #26)
by Mikhael Gorokhovski Fabien S. GodeferdGathering contributions by the most prominent researchers in a highly specialised field, this proceedings volume clarifies selected aspects of the physics of turbulent cascades and their statistical universalities under complex stationary and non-homogeneous conditions. Here, these conditions are induced by the presence of a gas/liquid interface, inertial particles, strong shear, rotation, MHD and stratification. By proposing different ways to model turbulence effects under these complex conditions, the book will be of considerable interest not only to academic researchers, but also to specialists and junior researchers in the domain of propulsion and power, as well as those whose work involves various applications related to atmospheric, oceanic and planetary physics.
