A Perilous Journey of Danger and Mayhem #3: The Final Gambit (Perilous Journey of Danger and Mayhem #3)
by Christopher HealyThe thrilling conclusion to Christopher Healy's funny, action-packed, acclaimed alt-history adventure!It is 1884, and Molly and Cassandra Pepper, Emmett Lee, and Emmett’s long-lost father are sailing back to New York following their death-defying adventure in Antarctica. Having discovered a subterranean world at the South Pole while saving the world from certain doom once again, surely their accomplishments will finally earn them the recognition they deserve.Unless, of course . . . well, you know by now.And so do the Peppers and Lees. They’re used to having their deeds covered up by the government in order to protect powerful men, and frankly, they’re sick of it. And when their return to New York doesn’t go the way they’d planned, they decide that maybe it’s best to go into hiding and accept that, perhaps, the forces aligned against them are just too great.As the 1884 presidential election approaches, however, our heroes discover a plot against leading candidate Thomas Edison that only they can stop. It’ll be up to them to decide whether to come out of hiding, make the perilous journey to Washington, DC, and do the right thing one last time. Even if it means risking everything they have left.

Periodic Mesoporous Organosilicas: Preparation, Properties and Applications (Springer Series in Materials Science #281)
by Chang-Sik Ha Sung Soo ParkThis book provides a comprehensive overview of the fundamental properties, preparation routes and applications of a novel class of organic–inorganic nanocomposites known as periodic mesoporous organosilicas (PMOs).Mesoporous silicas are amorphous inorganic materials which have silicon and oxygen atoms in their framework with pore size ranging from 2 to 50 nm. They can be synthesized from surfactants as templates for the polycondensation of various silicon sources such as tetraalkoxysilane. In general, mesoporous silica materials possess high surface areas, tunable pore diameters, high pore volumes and well uniformly organized porosity. The stable chemical property and the variable ability for chemical modification makes them ideal for many applications such as drug carrier, sensor, separation, catalyst, and adsorbent. Among such mesoporous silicas, in 1999, three groups in Canada, Germany, and Japan independently developed a novel class of organic–inorganic nanocomposites known as periodic mesoporous organosilicas (PMOs). The organic functional groups in the frameworks of these solids allow tuning of their surface properties and modification of the bulk properties of the material.The book discusses the properties of PMOs, their preparation, different functionalities and morphology, before going on to applications in fields such as catalysis, drug delivery, sensing, optics, electronic devices, environmental applications (gas sensing and gas adsorption), biomolecule adsorption and chromatography. The book provides fundamental understanding of PMOs and their advanced applications for general materials chemists and is an excellent guide to these promising novel materials for graduate students majoring in chemical engineering, chemistry, polymer science and materials science and engineering.
Periodic Motions to Chaos in a Spring-Pendulum System (Synthesis Lectures on Mechanical Engineering)
by Yu Guo Albert C. LuoThis book builds on the fundamental understandings, learned in undergraduate engineering and physics in principles of dynamics and control of mechanical systems. The design of real-world mechanical systems and devices becomes far more complex than the spring-pendulum system to which most engineers have been exposed. The authors provide one of the simplest models of nonlinear dynamical systems for learning complex nonlinear dynamical systems. The book addresses the complex challenges of the necessary modeling for the design of machines. The book addresses the methods to create a mechanical system with stable and unstable motions in environments influenced by an array of motion complexity including varied excitation frequencies ranging from periodic motions to chaos. Periodic motions to chaos, in a periodically forced nonlinear spring pendulum system, are presented through the discrete mapping method, and the corresponding stability and bifurcations of periodic motions on the bifurcation trees are presented. Developed semi-analytical solutions of periodical motions to chaos help the reader to understand complex nonlinear dynamical behaviors in nonlinear dynamical systems. Especially, one can use unstable motions rather than stable motions only.

Permaculture: Principles and Pathways Beyond Sustainability
by David HolmgrenDavid Holmgren brings into sharper focus the powerful and still evolving Permaculture concept he pioneered with Bill Mollison in the 1970s. It draws together and integrates 25 years of thinking and teaching to reveal a whole new way of understanding and action behind a simple set of design principles. The 12 design principles are each represented by a positive action statement, an icon and a traditional proverb or two that captures the essence of each principle. Holmgren draws a correlation between every aspect of how we organize our lives, communities and landscapes and our ability to creatively adapt to the ecological realities that shape human destiny. For students and teachers of Permaculture this book provides something more fundamental and distilled than Mollison's encyclopedic Designers Manual. For the general reader it provides refreshing perspectives on a range of environmental issues and shows how permaculture is much more than just a system of gardening. For anyone seriously interested in understanding the foundations of sustainable design and culture, this book is essential reading. Although a book of ideas, the big picture is repeatedly grounded by reference to Holmgren's own place, Melliodora, and other practical examples.

Spanning the bucolic Beltway suburbs of his childhood and the clandestine CIA and NSA postings of his adulthood, Permanent Record is the extraordinary account of a bright young man who grew up online--a man who became a spy, a whistleblower, and, in exile, the Internet's conscience. Written with wit, grace, passion, and unflinching candor, Permanent Record is a crucial memoir of our digital age and destined to be a classic.
Permeable Reactive Barrier: Sustainable Groundwater Remediation (Advances in Trace Elements in the Environment #1)
by Ravi NaiduRemediation of groundwater is complex and often challenging. But the cost of pump and treat technology, coupled with the dismal results achieved, has paved the way for newer, better technologies to be developed. Among these techniques is permeable reactive barrier (PRB) technology, which allows groundwater to pass through a buried porous barrier that either captures the contaminants or breaks them down. And although this approach is gaining popularity, there are few references available on the subject. Until now. Permeable Reactive Barrier: Sustainable Groundwater Remediation brings together the information required to plan, design/model, and apply a successful, cost-effective, and sustainable PRB technology. With contributions from pioneers in this area, the book covers state-of-the-art information on PRB technology. It details design criteria, predictive modeling, and application to contaminants beyond petroleum hydrocarbons, including inorganics and radionuclides. The text also examines implementation stages such as the initial feasibility assessment, laboratory treatability studies (including column studies), estimation of PRB design parameters, and development of a long-term monitoring network for the performance evaluation of the barrier. It also outlines the predictive tools required for life cycle analysis and cost/performance assessment. A review of current PRB technology and its applications, this book includes case studies that exemplify the concepts discussed. It helps you determine when to recommend PRB, what information is needed from the site investigation to design it, and what regulatory validation is required.
Permeation Grouting for Liquefaction Countermeasures: Implementation and Performance Evaluation
by Yoshihisa Sugimura Kiyonobu KasamaAcademic and industry experts describe the use of chemical (permeation) grouting beneath an airport runway to improve ground resistance to liquefaction. They present the cost, environmental, and operational benefits; specifications; methodology; and practical results of this cutting-edge method. Because transportation infrastructure such as ports and airports are required to operate even in the event of a large earthquake, they must be resilient against liquefaction.Through contributions from experts in academia and industry, this book describes the discovery of construction defects at three airports in Japan and the subsequent project to repair and strengthen the ground using chemical grouting using environmentally friendly colloidal silica, the first time this technique was used in Japan. This book first describes chemical grouting and its benefits, its specifications, and field investigation results of its ground improvement performance. Next, it demonstrates a numerical and probabilistic method to model spatial variability in material properties of field data on improved ground. Finally, it explains a performance-based verification for airport runway availability in terms of bearing capacity and runway flatness after a large earthquake. Through its clear explanations, this book enables readers to implement chemical grouting and enjoy the cost, environmental, access, and operational benefits of this technique over traditional methodologies that would require temporary site closure and large-scale excavation. Because the concept and methodology described in this book are applicable to various geological, geotechnical, and seismological conditions depending on the location and structural and operational conditions depending on the infrastructure type, this book is a useful resource for geotechnical and other infrastructure engineers who must strengthen the ground without disrupting normal operations.
