In today's world, reasonably predictable military operations have been replaced by low intensity conflicts-less predictable terrorist activities carried out by determined individuals or small groups that possess a wide range of backgrounds and capabilities. Because of the threats posed by this evolving type of warfare, civil engineers and emergency

Damage to critical energy infrastructure as a result of terrorism, criminal activity or natural disaster can have a significant impact at both a national and international level. Reducing the vulnerability of critical infrastructure to protect populations is therefore a high priority for governments worldwide, and high-quality training courses and advanced technologies are imperative in this regard. This book presents edited contributions from the NATO Advanced Training Course (ATC) entitled ‘Critical Energy Infrastructure Protection: Innovative Structures and Materials for Blast and Ballistic Protection’, held as a virtual event from 22 - 25 March 2021. The principal aim of the course was to gather specialists from NATO member and partner countries interested in protecting their critical infrastructure against terrorist attacks, and to share research and practical experience in this field. The meeting provided a forum for participants and speakers to disseminate their recent work, and also served to promote the exchange of ideas and international cooperation among scientists and engineers. The focus was on the physical protection of critical infrastructure in the face of certain types of intentional threat or accident, such as explosions, impacts and blast waves, and the experts shared their experience on topics including the mitigation of risks, classification of vulnerabilities, improvement of resilience, advanced protective materials, dynamic testing of materials and structures, simulations, and numerical prediction methods. The book will be of interest to all those whose work involves protecting critical infrastructure from the threat of terrorist attacks.
This volume gathers select proceedings of the 10th International Conference on Wave Mechanics and Vibrations (WMVC), held in Lisbon, Portugal, on July 4-6, 2022. It covers recent developments and cutting-edge methods in wave mechanics and vibrations applied to a wide range of engineering problems. It presents analytical and computational studies in structural mechanics, seismology and earthquake engineering, mechanical engineering, aeronautics, robotics and nuclear engineering among others. The volume will be of interest for students, researchers, and professionals interested in the wide-ranging applications of wave mechanics and vibrations.
Although much research focuses on investigating the responses of reinforced concrete (RC) structures under sole impact or blast loads, the responses of RC structures under a combination of impact and blast loads currently represent a gap in our knowledge. The combined actions of impact and blast loadings may be applied to RC structures during accidental or intentional collision of vessels, vehicles, etc., carrying explosive materials. A comprehensive study on the vulnerability of various structural members is carried out using finite element (FE) simulations under combination of impact and blast loads with the variations of various loading- and structural-related parameters and key parameters. This book introduces various structural analysis approaches for concrete structures when subjected to extreme loads such as impact and blast loadings. The theory of the combinations of impact and blast loads is proposed that can provide primary insights to the specific readers to develop new ideas in impact and blast engineering, including combined actions of extreme loads arising from real-world intentional or accidental events. This book will be of value to students (undergraduate or postgraduate), engineers, and researchers in structural and civil engineering, and specifically, those who are studying and investigating the performances of concrete structures under extreme loads.
There has been a large increase in the commercial use of integrated crop/pest management methods for pest and disease control on a wide range of crops throughout the world since the first edition of this book. The completely revised second edition of the bestselling Biological Control in Plant Protection: A Color Handbook continues the objective of providing a handbook with profiles and full-color photographs of as many examples of biological control organisms from as wide a global area as possible. It is designed to help readers anticipate and recognize specific problems of pest management and then resolve them using the natural enemies of pests—parasites, predators, and pathogens. The authors first describe the impact of predator-prey relationships on host plant species in arable, orchard, and protected environments. The main sections of the book include profiles of pests, beneficial arthropods (insects and mites), and beneficial pathogens (bacteria, fungi, viruses, and nematodes), featuring a tabular pest identification guide. Descriptions of biocontrol organisms are divided into four sections: species characteristics, lifecycle, crop/pest associations, and influences of growing practices. The text is illustrated throughout with color photographs of the highest quality. This revised edition helps readers more fully understand the concepts and practice of biological control and integrated pest management. All chapters have been updated and expanded, and more than 300 new photographs have been added. The second edition covers new beneficial organisms and pest profiles, and it includes a new chapter on the practical aspects and application of biological control. It also contains a new final chapter that puts biological control in perspective, discussing interactions that occur when using biocontrol for population management as well as some of the possible mechanisms of biocontrol.

This book introduces BlastSim - a physics-based simulation platform to model and simulate suicide bombing events. The BlastSim software is designed to test, analyze, and validate the results of different explosive and injury model combinations under various conditions with different sets of parameters, such as explosive and crowd formation characteristics, blockage and human shielding effects, fragmentation and shrapnel, and the bomber's position in 2- and 3-dimensional environments. The suicide bombing event can also be re-created for forensic analysis. The number of fatalities and injured after a suicide bombing event can be predicted using this software with 91% accuracy. The assessment of an explosion's effect on a crowd can lead to better management of disasters, triage of patients, locating blast victims under the debris, development of protective gear, and safe distance recommendations to reduce casualties.
