The performance of grounding grids is critical in safeguarding electrical systems from damage during fault conditions and lightning strikes. Their effectiveness may be compromised under extreme conditions, leading to system failures or safety incidents. Despite advancements in grounding technologies, there remains a need to evaluate and enhance the performance of grounding grids to withstand these scenarios. Engineers, researchers, and industry stakeholders must collaborate to advance testing methodologies, improve design standards, and develop innovative solutions. Effective research and practical improvements in grounding grid systems will ensure reliable protection is provided to safeguard infrastructure and improve safety. Performance of Grounding Grids at Faulty and Lightning Strokes Conditions presents the characteristics of grounding electrodes when subjected to lightning, including the impacts of soil ionization with frequency, soil resistivity, and permittivity variations. The study presents the effects of different reflection factors on human safety through various methods and simulations. This book covers topics such as fault currents, soil ionization, and grounding systems, and is a useful resource for scientists, engineers, technologists, academicians, researchers, and business owners.

Geotechnical Aspects of Underground Construction in Soft Ground comprises a collection of 112 papers, the Fujita Lecture, three Special Lectures and the Bright Spark Lecture presented at the Tenth International Symposium on Geotechnical Aspects of Underground Construction in Soft Ground, held in Cambridge, United Kingdom, 27-29 June 2022. This second edition includes four general reports on the symposium themes. The symposium is the latest in a series which began in New Delhi in 1994, and was followed by symposia in London (1996), Tokyo (1999), Toulouse (2002), Amsterdam (2005), Shanghai (2008), Rome (2011), Seoul (2014) and Sao Paulo (2017). This was organised by the Geotechnical Research Group at the University of Cambridge, under the auspices of the Technical Committee TC204 of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE). Geotechnical Aspects of Underground Construction in Soft Ground includes contributions from more than 25 countries on research, design and construction of underground works in soft ground. The contributions cover: Field case studies Sensing technologies and monitoring for underground construction in soft ground Physical and numerical modelling of tunnels and deep excavations in soft ground Seismic response of underground infrastructure in soft ground Design and application of ground improvement for underground construction Ground movements, interaction with existing structures and mitigation measures The general reports give an overview of the papers submitted to the symposium, covered in four technical sessions. The proceedings include the written version of the five invited lectures covering topics ranging from developments in geotechnical aspects of underground construction, tunnelling and groundwater interaction (short and long-term effects), the influence of earth pressure balance shield tunnelling on pre-convergence and segmental liner loading (field observations, modelling and implications on design). Similar to previous editions, Geotechnical Aspects of Underground Construction in Soft Ground represents a valuable source of reference on the current practice of analysis, design, and construction of tunnels and deep excavations in soft ground. The book is particularly aimed at academics and professionals interested in geotechnical and underground engineering.

Environmental And Engineering Geology is a component of Encyclopedia of Environmental and Ecological Sciences, Engineering and Technology Resources in the global Encyclopedia of Life Support Systems (EOLSS), which is an integrated compendium of twenty one Encyclopedias. The Theme on Environmental and Engineering Geology with contributions from distinguished experts in the field discusses matters of great relevance to our world such as: engineering and environmental geology, and their importance in our life. It also includes a discussion of some new applications of geoscience, such as medical geology, forensic geology, use of underground space for human occupancy, and geoindicators. These four volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

Sports Science has increasingly developed both as an area of research and as a university subject. This book gives an authoritative account of the biological basis of athletic performance and training, based on an analysis of scientific and medical research in the area. The findings are presented in such a way that anyone involved in training for high-level sport will find the information accessible and of interest.

This book considers the properties and behaviour of cement-based materials from the point of view of composite science and technology. It deals particularly with newer forms of cement-based materials and also with a composite approach to conventional materials and their special properties. Emphasis is put on non-conventional reinforcement and desig
