Skull-base surgery is a minimally invasive endoscopic procedure, which involves the surgeon inserting instruments through the natural openings in the skull—the nose or mouth—or by making a small hole just above the eyebrow. This type of surgery requires a team of specialists, which may include ENT (ear, nose, and throat), maxillofacial and neurosurgeons, as well as radiologists. The craniovertebral junction (CVJ) has a unique anatomical bone and neurovascular structure, which not only separates the subaxial cervical spine but also provides a special cranial flexion, extension and axial rotation pattern. As such, a sound knowledge of the basic principles of spine instrumentation and the region’s kinematics are essential when it comes to strategic preoperative planning.

An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions. Environmental changes caused by LIPs and SLIPs include rapid global warming, global cooling ('Snowball Earth'), oceanic anoxia events, mercury poisoning, atmospheric and oceanic acidification, and sea level changes.

Container industry is gathering pace as vessels are becoming increasingly larger, with the volume of containers carried regularly exceeding 23,000 per vessel. This means the scope for accidents and incidents is also increasing exponentially.

This book includes the insights of a seminar that was held at IUAV University of Venice, on May 29th and 30th featuring 10 speakers. 8 speakers, 2 moderators, and 1 organizer from the seminar, plus 10 other authors contributed to this book. The writers’ expertise spans from local climate adaptation planning, public policy analysis, climate and environmental finance, and climate adaptation advocacy to multi-risk analysis, GIS, disaster risk management, ecosystem services assessment, urban geography, art, and civic engagement. The book contents address adaptation and flood risk mitigation along the Science-Policy-Action path - both theoretical and operative perspectives are discussed. EU climate adaptation policy and finance, climate adaptation implementation, flood risk analysis, nature-based solutions, blue ecosystem services, regional adaptation planning, and critical infrastructure adaptation are the topics investigated in depth by the writers.

This is the second of two volumes that together provide a global overview of the impact of agriculture on soil degradation, tracing the most critical drivers like the use and abuse of agrochemicals, mechanization, overgrazing, irrigation, slash and burn agriculture, and the use of plastics.

This handbook provides both a comprehensive overview and deep insights on the state-of-the-art methods used in wind turbine aerodynamics, as well as their advantages and limits. The focus of this work is specifically on wind turbines, where the aerodynamics are different from that of other fields due to the turbulent wind fields they face and the resultant differences in structural requirements. It gives a complete picture of research in the field, taking into account the different approaches which are applied. This book would be useful to professionals, academics, researchers and students working in the field.

This textbook provides in-depth treatment of all systems associated with wind energy, including the aerodynamic and structural aspects of blade design, the flow of energy and loads through the wind turbine, the electrical components and power electronics including control systems. It explains the importance of wind resource assessment techniques, site evaluation and ecology and describes the integration of wind farms into the electrical grid. The reader will also become familiar with the offshore technology, the youngest and most promising aspect of wind energy.

This book compiles the groundbreaking research conducted by the Collaborative Research Center (CRC) 871, centered around the "Regeneration of Complex Capital Goods." This comprehensive work unveils an array of innovative methods developed through CRC 871, designed to revitalize and enhance the functional attributes of these critical assets. From non-destructive characterization of heavily stressed turbine components to the dynamic behavior of regenerated structural elements, each chapter offers a meticulous exploration of diverse facets in the field. The book also addresses the crucial consideration of variability in repair processes and material properties, as well as the comprehensive control of regeneration processes. With insights into simulation-based process design, fast measurement techniques, and resilience-based decision criteria, this volume provides a comprehensive view of the cutting-edge approaches employed. Moreover, readers will find a detailed process chain for condition-based regeneration, offering a practical framework for implementation. Finally, the book sheds light on the importance of targeted public relations in disseminating the invaluable research carried out by Collaborative Research Center 871. This extensive compilation not only showcases the scientific rigor behind maintaining complex capital goods but also demonstrates the collaborative efforts that brought together experts from various fields to push the boundaries of regeneration technology.

This handbook deals with the vast subject of thermal management of engines and vehicles by applying the state of the art research to diesel and natural gas engines. The contributions from global experts focus on management, generation, and retention of heat in after-treatment and exhaust systems for light-off of NOx, PM, and PN catalysts during cold start and city cycles as well as operation at ultralow temperatures. This book will be of great interest to those in academia and industry involved in the design and development of advanced diesel and CNG engines satisfying the current and future emission standards.

Due to limited non-renewable resources and climate change problems, the global energy sector must be transformed from fossil fuel dominated to renewable energy based. However, due to constraints of resources, technology, locked capital in existing energy systems, limited financial support, and associated risks in investment, etc., this transformation is not expected to occur rapidly. Rather there should be an energy transition path with planned replacement of fossil fuel-based systems to renewable-based ones. Large-scale renewable power is yet to be dominant globally. Distributed renewable power is appearing to be more common as its implementation requires smaller investments with lesser financial risks. There are several options of such distributed renewable power with great prospects at different locations. Simultaneously, there are many challenges to overcome for successful implementation of such projects. These challenges are also multi-dimensional. In this book, several chapters address bright prospects of several options of distributed renewable power. Simultaneously, other chapters address challenges of implementation of such technologies. The chapters together cover a wide perspective of both prospects and associated challenges to be addressed for it. Chapters include technological issues, optimization of energy systems, logistics and policies, case studies etc. Researchers, industry professionals, and students can benefit from this book.

This book discusses the geology, hydrogeology, and water quality/geochemistry of karst systems in geologically young terrain, using the state of Florida as an example. Also discussed are sinkhole-development models; sinkhole risk; eogenetic karst features developed in rocks as young as 125,000 years and as old as 65 million years; and karst landscapes of Florida, including regional geology and geomorphology with important examples of karst features, such as springs, sinkholes, caves, and other karst landforms. The eogenetic karst of Florida is largely covered and this book extensively discusses the interactions of karst processes with sand- and clay-rich cover materials.

This book presents selected, peer-reviewed proceedings of the International Conference on Advanced Mechanical Engineering, Automation and Sustainable Development 2021 (AMAS2021), held in the city of Ha Long, Vietnam, from November 4 to 7, 2021.
