The use of bioreactors in food ingredient production has expanded rapidly in recent years. These processes create a controlled environment that is tailored to the specific needs of each microorganism, while also minimizing their environmental impact. However, to optimize the implementation of these processes, it is necessary to master a number of scientific concepts relating to material and heat balances, thermodynamics, microbial kinetics, extrapolation and agitation techniques, as well as the techno-economic analysis of processes. This book aims to provide an exhaustive and precise presentation of all of these concepts, making them accessible to students, researchers and professionals alike. Bioreactor Implementation in the Agro-Food Industries is structured in two complementary parts. The first part outlines the essential principles of bioreactor engineering. This knowledge is essential if we are to master the biological and physico-chemical processes that take place in bioreactors. The second part presents practical examples of the use of bioreactors for the production of several ingredients and metabolites of interest.

Numerical Methods for Strong Nonlinearities in Mechanics deals with recent advances in the numerical treatment of contact/friction and damage phenomena. Although physically distinct, these phenomena both lead to a strong nonlinearity in the mechanical problem, therefore limiting the regularity of the problem, which is now non-differentiable. This has two direct consequences: on the one hand, the mathematical characteristics of the problem deviate from wellestablished forms, requiring innovative discretization schemes; on the other hand, the low regularity makes it particularly difficult to solve the corresponding large-scale algebraic systems robustly and efficiently. In addition, neither the uniqueness, nor the existence of solutions, remain assured, resulting in bifurcation points, limit loads and structural instabilities, which are always tricky to overcome numerically.

There are currently over eight billion people on Earth: how did we arrive at the current distribution of humans on the planet? What shape is it taking, and how will it evolve? This book proposes an original answer to this, which is based on the explicit desire to place settlement at the heart of its questioning, by varying the level of analysis from global to local. After recalling how humans colonized the entire planet, this book presents their current distribution, which is predominantly urban. Population dynamics (birth rate, death rate and migration) are driving changes - including the demographic decline of certain regions - which are presented and explained from the angle of residential mobility and international migration, as well as the impact of ongoing climate change. Global Settlement Dynamics concludes with a discussion of the future of these settlements, based on data from the United Nations, and the question of the sustainability of human settlements on Earth.

Digital evolution, whether through Internet advances or the development of connected objects, has triggered a veritable societal revolution. Thanks to technological advances, e-health services enable healthcare professionals to monitor patients in real time.

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.

Everyday mobility is neither favorable nor unfavorable to health. While it can facilitate social interactions, increase access to remote services, or encourage physical activity, it can also generate pollution, promote the spread of epidemics or cause traffic accidents. This book presents different facets of the relationship between daily mobility and health, focusing on the environments (geographical, social and political) that people live and move around in. 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.
