As a low carbon energy source, nuclear energy plays a reinforced role in a sustainable electricity mix. However, strengthening the share of nuclear energy implies the guarantee of safe, long-term operation of current systems and potentially the fostering of new constructions. Service life extension as well as the design of future nuclear power plants relies on the availability of robust and qualified structural materials, and their manufacturing processes. The science and engineering of materials are key in selecting robust material solutions and predicting aging mechanisms. Materials and Processes for Nuclear Energy Today and in the Future reviews different reactor concepts and fuel management systems. Nuclear equipment has to maintain integrity under extreme conditions, such as high temperature, radiation, loads and/or corrosive environments. This book analyzes the requirements on components, and introduces reference solutions regarding materials and processes. It describes the materials main properties, their limits and the current R&D trends. Lastly, innovations are discussed, such as materials with enhanced properties, advanced manufacturing or using AI.

The advent of the automated and connected vehicle will require the implementation of high-performance communication systems: Cooperative Intelligent Transport Systems (C-ITS). However, controlling and managing these C-ITS is complex. A number of points need to be jointly considered: 1) a high level of performance to guarantee the Quality of Service requirements of vehicular applications (latency, bandwidth, etc.); 2) a sufficient level of security to guarantee the correct operation of applications; and 3) the implementation of an architecture that guarantees interoperability between different communication systems. In response to these issues, this book presents new solutions for the management and control of Intelligent and Cooperative Transport Systems. The proposed solutions have different objectives, ranging from increased safety to higher levels of performance and the implementation of new, more energyefficient mechanisms.

Low-temperature thermochronology has become an essential tool when studying near-surface geological processes. Time-temperature constraints are vital to quantify and describe a large variety of geological processes, such as relief building, erosion and sedimentation or the maturation of organic matter in sedimentary basins. After a brief history covering the discovery of fission tracks to their first applications in geochronology, Fission-track Thermochronology presents a complete description of not only the fission-track, but also the (U Th Sm)/He thermochronology approaches, both on basement rocks and on sediments. Firstly, the physical and chemical processes that underlie these techniques are addressed, and the analytical methods are described in detail. A particular focus is placed on the latest developments, such as the use of laser-ablation ICP-MS, and a whole chapter is dedicated to statistical modeling of the data. Finally, numerous examples of applications to geological questions will provide the reader with a comprehensive overview of the possibilities of low temperature thermochronology in solving geological and geomorphological questions.

Reducing consumption is now an absolute necessity for the future of our environment. The circular economy is designed to reduce resource wastage and waste production, but also enables waste recovery, leading to the creation of secondary resources. All materials, regardless of how they have been processed, can be reused. Recycling, a Challenge for the Circular Economy begins its analysis by raising awareness of the role of each of us in reducing the volume of individual waste. The book then outlines the strategies and challenges involved in recycling a wide range of materials, from minimally processed (wood, glass, building materials or polluted soil) to highly processed (electrical and electronic waste, batteries, magnets or plastics). Aspects of resource availability are also discussed, as well as ways of addressing the dynamic cycle of materials in the context of ever-increasing demand.

With the increasing proliferation of data and the systematization of geographic information referencing, maps are now a major concern not only for specialists, but also for urban planning and development organizations and the general public. However, while producing a map may seem straightforward, the actual process of transforming data into a useful map with a specific purpose is characterized by a series of precise operations that require knowledge in a variety of fields: statistics, geography, cartography and so on. Handling and Mapping Geographic Information presents a wide range of operations based on a variety of examples. Each chapter adopts a different approach, explaining the methodological choices made in relation to the theme and the pursued objective. This approach, encompassing the entire map production process, will enable all readers, whether students, researchers, teachers or planners, to understand the multiple roles that maps can play in the analysis of geographical data.

Since their discovery by Barbara McClintock in the mid-20th century, the importance of transposable elements in shaping the architecture, function and evolution of genomes has gradually been unveiled. These DNA sequences populate nearly all genomes and are viewed as genomic parasites. They are mobile, capable of proliferating within genomes and also commonly travel between species. These elements are mutagenic and are responsible for several human genetic disorders, but they also constitute a major source of genetic diversity. Some insertions have beneficial effects for the host and are selected for, giving rise to significant evolutionary innovations. Their dynamics within genomes are intricate, as are their interactions with other genome components. To limit their proliferation, the genome has evolved sophisticated defense mechanisms. While researchers commonly use these elements as genetic tools, their identification in newly sequenced genomes remains a challenge due not only to their extensive diversity, but also their large copy numbers.

Milk is considered a complete food, consumed at all stages of life. It is transformed into numerous products, fermented or not, as well as into a variety of ingredients, in order to preserve it or some of its constituents from a few days to a few years.

It analyzes the role of mobility in the mechanisms of environmental exposure and diffusion, as well as the resulting health inequalities. It deals with active modes of travel (mainly walking and cycling) and the local contexts that are conducive to them. Finally, it offers a critical reading of the place given to everyday mobility in policies to combat obesity and rationalize regional healthcare provision.

This book helps readers to understand the past (overview of technologies), current (how they are evolving) and the future (adaptation to new trends) of two representative communication technologies, Wi-Fi and Bluetooth. Wi-Fi and Bluetooth are technologies that are very familiar to us in our everyday lives. However, these technologies have evolved throughout the years to meet the continuously changing demands of users. Evolution of these technologies can be difficult to understand, even for professionals in the field of computer science and engineering, due to the extensiveness and complexity of written documents (technical standards and specifications are not very reader-friendly!). Next Generation of Bluetooth and Wi-Fi summarizes the key functions of Wi Fi and Bluetooth to show how they adapt to new environments and requirements. We introduce the new concepts that allow them to shift into the new paradigm of IoT and beyond, and we propose ideas and insights on how they could also possibly evolve in the future, integrated with other fascinating technologies.

Earth observation has witnessed a unique paradigm change in the last decade with a diverse and ever-growing number of data sources.

Multitemporal Earth Observation Image Analysis provides illustrations of recent methodological advances in data processing and information extraction from imagery, with an emphasis on the temporal dimension uncovered either by recent satellite constellations (in particular the Sentinels from the European Copernicus programme) or archival aerial images available in national archives. The book shows how complementary data sources can be efficiently used, how spatial and temporal information can be leveraged for biophysical parameter estimation, classification of land surfaces and object tracking, as well as how standard machine learning and state-of-the-art deep learning solutions can solve complex problems with real-world applications.

This book provides an understanding of ultrasound imaging principles and how the field is evolving to better probe living systems. Today, widely-used imaging systems visualize structures and blood flow within the body in real-time. Signal analysis, hardware and contrast agent innovations are extending the capacity of ultrasound to assess tissue elasticity, to enable three-dimensional viewing of moving structures and to detect vessels smaller than the wavelength-limited resolution. Techniques are also being designed so that we are less impeded by bones in the sound path, as well as to combine light and sound to detect optically-absorbent structures within the body. After an introductory chapter reviewing the key basic concepts, each chapter presents a detailed explanation focusing on a specific set of key principles and then shows the related techniques in each domain that are currently being refined to evaluate living systems in greater depth.

Despite their many common features (mechanical behavior, multi-scale structure, evolutionary and living characteristics, etc.), the tissues that make up the human body each have specific characteristics linked to their function, which require the development of dedicated experimental, theoretical and numerical methods. Mechanics of Living Tissues brings together the work of a number of experts to provide an overview of the most recent approaches developed to study the biomechanical behavior of these soft tissues, in order to understand their structure and apparent behavior. Specific tissues are analyzed across the chapters with the aim of developing solutions that address the clinical problems encountered. Conclusions are then drawn regarding future methods that will improve the current state of knowledge of the behavior of these living tissues, in particular with a view to predicting the effect of a pathology or medical procedure on their apparent properties.

Many practical examples are also provided throughout the book.

Organizations communicate in complex and various ways, and the context is mainly characterized by the pervasiveness of the digital ecosystem, including the Web, social networks and the Internet of data. However, its information delivery cannot overlook the requirements of multicultural communications at a variety of levels. Digital Presences of Organizations highlights the communication roadblocks faced by organizations as they emerge, arising not only from issues encountered on their own websites, but also as they construct online narratives. This multi-faceted and multi-strategy digital presence of organizations is addressed via three main thematic axes. The first focuses on differentiated strategies (content, services, interaction) that can be observed depending on the types of organizations and their users. The second examines the cultural dimension of websites, ranging from the local to the global. Finally, the third focuses on the role of narration in organizations' online communication strategies.

This book deals with risk management by focusing on microbiological risks. Throughout the food chain, foodstuff may be exposed to dangerous agents that can potentially affect its quality and thus the health of consumers. A good knowledge of the strategies and means of control implemented along the food chain after the primary production stage is a necessary condition and a prerequisite for any further improvement, but it is not sufficient. Indeed, in order to better prevent and therefore control these risks, it is essential to study both the phenomena of surface contamination and those relating to the elimination of this contamination by cleaning and disinfection operations in order to know the main mechanisms. Thanks to this, a certain number of innovations can already be proposed (new surfaces, new materials and cleaning and disinfection procedures, etc.) for future developments on an industrial or domestic scale.
