Microbial Transport Systems

The use and management of multimodal transport systems, including car-pooling and goods transportation, have become extremely complex, due to their large size (sometimes several thousand variables), the nature of their dynamic relationships as well as the many constraints to which they are subjected. The managers of these systems must ensure that the system works as efficiently as possible by managing the various causes of malfunction of the transport system (vehicle breakdowns, road obstructions, accidents, etc.). The detection and resolution of conflicts, which are particularly complex and must be dealt with in real time, are currently processed manually by operators. However, the experience and abilities of these operators are no longer sufficient when faced with the complexity of the problems to be solved. It is thus necessary to provide them with an interactive tool to help with the management of disturbances, enabling them to identify the different disturbances, to characterize and prioritize these disturbances, to process them by taking into account their specifics and to evaluate the impact of the decisions in real time. Each chapter of this book can be broken down into an approach for solving a transport problem in 3 stages, i.e. modeling the problem, creating optimization algorithms and validating the solutions. The management of a transport system calls for knowledge of a variety of theories (problem modeling tools, multi-objective problem classification, optimization algorithms, etc.). The different constraints increase its complexity drastically and thus require a model that represents as far as possible all the components of a problem in order to better identify it and propose corresponding solutions. These solutions are then evaluated according to the criteria of the transport providers as well as those of the city transport authorities. This book consists of a state of the art on innovative transport systems as well as the possibility of coordinating with the current public transport system and the authors clearly illustrate this coordination within the framework of an intelligent transport system.

The multimodal transport network customers need to be oriented during their travels. A multimodal information system (MIS) can provide customers with a travel support tool, allowing them to express their demands and providing them with the appropriate responses in order to improve their travel conditions. This book develops methodologies in order to realize a MIS tool capable of ensuring the availability of permanent multimodal information for customers before and while traveling, considering passengers mobility.

This book explains the ecology of viruses by examining their interactive dynamics with their hosting species (in this volume, in microbes and plants), including the types of transmission cycles that viruses have evolved encompassing principal and alternate hosts, vehicles, and vectoring species. Examining virology from an organismal biology approach and focusing on the concept that viral infections represent areas of overlap in the ecologies of the involved species, Viral Ecology is essential for students and professionals who either may be non-virologists or virologists whose previous familiarity has been very specialized.

In accordance with its predecessor, the completely revised and expanded Second Edition of Modern Microbial Genetics focuses on how bacteria and bacteriophage arrange and rearrange their genetic material through mutation, evolution, and genetic exchange to take optimal advantage of their environment. The text is divided into three sections: DNA Metabolism, Genetic Response, and Genetic Exchange. The first addresses how DNA replicates, repairs itself, and recombines, as well as how it may be manipulated. The second section is devoted to how microorganisms interact with their environment, including chapters on sporulation and stress shock, and the final section contains the latest information on classic exchange mechanisms such as transformation and conjugation. Chapters include: Gene Expression and Its Regulation Single-Stranded DNA Phages Genetic Tools for Dissecting Motility and Development of Myxococcus xanthus Molecular Mechanism of Quorum Sensing Transduction in Gram-Negative Bacteria Genetic Approaches in Bacteria with No Natural Genetic Systems The editors also cultivate an attention to global regulatory systems throughout the book, elucidating how certain genes and operons in bacteria, defined as regulons, network and cooperate to suit the needs of the bacterial cell. With clear appreciation for the impact of molecular genomics, this completely revised and updated edition proves that Modern Microbial Genetics remains the benchmark text in its field.

Healthy seeds and propagules are the basic requirement for producing good grains, fruits and vegetables needed for human survival and perpetuation. Dispersal of microbial plant pathogens via seeds and propagules has assumed more importance than other modes of dispersal, as infected seeds and propagules have the potential to become the primary sources of carrying pathogen inoculum for subsequent crops. Several diseases transmitted through seeds and propagules have been shown to have the potential to damage economies as a result of huge quantitative and qualitative losses in numerous crops. Hence, it is essential to rapidly detect, identify and differentiate the microbial plant pathogens present in seeds and propagules precisely and reliably, using sensitive techniques. Microbial Plant Pathogens: Detection and Management in Seeds and Propagules provides a comprehensive resource on seed-borne and propagule-borne pathogens. Information on the biology of microbial pathogens, including genetic diversity, infection process and survival mechanisms of pathogens and epidemiology of diseases caused by them, are discussed critically and in detail to highlight weak links in the life cycles of the pathogens. Development of effective disease management systems, based on the principles of exclusion and eradication of pathogens and immunization of crop plants to enhance the levels of resistance of cultivars to diseases, has been effective to keep the pathogens at bay. The need for production of disease-free seeds/propagules has been emphasized to prevent the carryover of the inoculum to the next crop or introduction of the pathogens to other locations. Effectiveness of adopting simple cultural practices and development of cultivars resistant to diseases through traditional breeding methods or biotechnological approach have resulted in reducing the pathogen inoculum and disease incidence. Although application of different chemicals may reduce the disease incidence effectively, biological management of crop diseases, employing potential biological control agents have to be preferred to preserve the agroecosystems. Greater efforts have to be made to integrate compatible strategies to enhance the effectiveness of diseases management systems. Protocols appended at the end of relevant chapters form a unique feature of this book to enable the researchers to fine-tune their projects. This 2 volume set provides comprehensive and updated information about the economically-important groups of microbial plant pathogens carried by seed and propagules. Graduate students, researchers and teachers of plant pathology, plant protection, microbiology, plant breeding and genetics, agriculture and horticulture, as well as certification and quarantine personnel will find the information presented in this book useful.

In recent years, the systems designed to support activity in the fields of banking, health, transportation, space, aeronautics, defense, etc. have become increasingly larger and more complex. With the growing maturity of information and communication technologies, systems have been interconnected within growing networks, yielding new capabilities and services through the combination of system functionalities. This has led to a further increasing complexity that has to be managed in order to take advantage of these system integrations. The book is divided into two parts. The first part addresses the concept and practical illustrations of a “system of systems” and is a multidisciplinary introduction to the notion of a “systems of systems” that is discussed extensively in the current scientific and technical literature. After a critical comparison of the different definitions and a range of various practical illustrations, this part provides answers to key questions such as what a system of systems is and how its complexity can be mastered. The second part, described as “systems-of-systems engineering: methods and tools”, focuses on both engineering and modeling, and standardization issues that are critical to deal with the key steps in systems of systems engineering: namely eliciting stakeholder needs, architecture optimization, integration of constituent systems, qualification, and utilization.
