Mechanics
by Masud Chaichian Anca Tureanu Ioan MerchesMechanics is one of the oldest and at the same time newest disciplines, in the sense that there are methods and principles developed first in mechanics but now widely used in almost all branches of physics: electrodynamics, quantum mechanics, classical and quantum field theory, special and general theory of relativity, etc. More than that, there are some formalisms like Lagrangian and Hamiltonian approaches, which represent the key stone for the development of the above-mentioned disciplines. During the last 20-25 years, classical mechanics has undergone an important revival associated with the progress in non-linear dynamics, applications of Noether's theorem and the extension of variational principles in various interdisciplinary sciences (for instance, magnetofluid dynamics). Thus, there ought to exist a book concerned with the applied analytical formalism, first developed in the frame of theoretical mechanics, which has proved to be one of the most efficient tools of investigation in the entire arena of science.The present book is an outcome of the authors' teaching experience over many years in different countries and for different students studying diverse fields of physics. The book is intended for students at the level of undergraduate and graduate studies in physics, engineering, astronomy, applied mathematics and for researchers working in related subjects. We hope that the original presentation and the distribution of the topics, the various applications in many branches of physics and the set of more than 100 proposed problems, shall make this book a comprehensive and useful tool for students and researchers.

Mechanics
by Florian ScheckPurpose and Emphasis. Mechanics not only is the oldest branch of physics but was and still is the basis for all of theoretical physics. Quantum mechanics can hardly be understood, perhaps cannot even be formulated, without a good knowledge of general mechanics. Field theories such as electrodynamics borrow their formal framework and many of their building principles from mechanics. In short, throughout the many modem developments of physics where one fre quently turns back to the principles of c1assical mechanics its model character is feIt. For this reason it is not surprising that the presentation of mechanics reflects to some extent the development of modem physics and that today this c1assical branch of theoretical physics is taught rather differently than at the time of Arnold Sommerfeld, in the 1920s, or even in the 1950s, when more emphasis was put on the theory and the applications of partial-differential equations. Today, symme tries and invariance principles, the structure ofthespace-time continuum, and the geometrical structure of mechanics play an important role. The beginner should realize that mechanics is not primarily the art of describing block-and-tackles, coIIisions of billiard balls, constrained motions of the cylinder in a washing ma chine, or bicycle riding.
Mechanics and Geometry of Enriched Continua
by Luis EspathThis monograph presents a comprehensive and rigorous new framework for the theoretical description and modelling of enriched continua. In other words, continua that exhibit more complex behaviour than their conventional counterparts and, in particular, multicomponent systems. It employs gradient theories, exhibiting multiple transition layers described by phase fields. As a point of departure, we account for multiple continuum kinematic processes, including motion and various phase fields. These gradient theories arise by considering various kinematic processes which are tightly linked to the level of the arbitrariness of the Euler–Cauchy cuts. The surface defining the Euler–Cauchy cut may lose its smoothness along a curve, and the curve may also lose its smoothness at a point. Additionally, we postulate the principle of virtual power on surfaces. Then, the first and second laws of thermodynamics with the power balance provide suitable and consistent choices for the constitutive equations. Finally, the complementary balances, namely the balances on surfaces, are tailored to coincide with different parts of the boundaries of the body. These surface balances are then called environmental surface balances and aid in determining suitable and consistent boundary conditions. Ultimately, the environmental surface power balance is relaxed to yield an environmental surface imbalance of powers, rendering a more general type of boundary condition.A detailed introduction sets the scene for the mathematical chapters that follow, ensuring that graduate students and newcomers can profit from the material presented.
Mechanics of Bio-Sediment Transport
by Wei Cheng Hongwei Fang Lei Huang Huiming Zhao Yishan Chen Mehdi Fazeli Qianqian ShangThe main focus of this book is the transport mechanics of sediment particles coated with microbial biofilm, which is called bio-sediment. The book also addresses the question of how to measure and simulate the considerable variation in the properties of natural sediment associated with microbial biofilm, ranging from the micro-scale surface morphology to the macro-scale sediment transport. Nowadays most studies to elucidate the mechanisms of sediment transport have concentrated on physical-chemical sediment properties, little work explicitly coupled sediment dynamics and the environmental effects under the influence of micro-ecosystem, thus leaving a serious gap in water and sediment sciences as well as water ecological research. With respect to physical-chemical sediment properties, this book has been undertaken to evaluate and quantify the effect of biological factors - biofilm on sediment transport mechanics. The chapters cover topics including development of bio-sediment and its properties; model of biofilm growth on sediment substratum; bedform and flow resistance of bio-sediment bed; incipient velocity and settling velocity of bio-sediment; bedload and suspended load transport for bio-sediment; numerical simulation of bio-sediment transport. Besides, the measurement technology, analysis method and expression approach introduced in this book combine the characteristics of hydraulic, environmental and microbial research, having more immediate innovation. This book will be of interest to researchers, managers, practitioners, policy and decision makers, international institutions, governmental and non-governmental organizations, educators, as well as graduate and undergraduate students in the field of hydraulics and river dynamics. It will help to understand the relevance of sediment transport and biofilm growth under the role of aqueous micro-ecosystem, to introduce better tools for the simulation and prediction of bio-sediment transport, and to provide a scientific basis and application foundation for the research of interaction between sediment particles and ecological and environmental factors.

Mechanism-Based Assessment of Structural and Functional Behavior of Sustainable Cottonid (Werkstofftechnische Berichte │ Reports of Materials Science and Engineering)
by Ronja Victoria ScholzRonja Victoria Scholz assesses the performance of cellulose-based Cottonid for implementation as sustainable construction material. Quasi-static and fatigue tests are performed in varying hygrothermal test conditions using mechanical testing systems in combination with integrable climate chambers. To investigate humidity-driven actuation properties, customized specimen holders are designed. Accompanying microstructural in situ experiments in analytical devices enable a profound understanding of effective material-specific damage and failure mechanisms. The findings are transferred into strength-deformation diagrams as well as Woehler curves, which enable a comparative evaluation of several process-related and environmental influencing factors and can directly be used for dimensioning of Cottonid elements for structural applications. The interpretation of thermoelastic material reponse during loading is used as scientific value for lifetime prediction. Comprehensive investigations on industrial standard materials as well as structurally optimized Cottonid variants provide a scientific basis for categorizing material’s structural and functional performance towards common technical plastics and wood.
Mechanisms for Long-Term Innovation: Technology and Business Development of Reverse Osmosis Membranes (Advances in Japanese Business and Economics #31)
by Yaichi Aoshima Masatoshi FujiwaraThis book explores how a long-term innovation can take place based on historical analyses of the development of reverse osmosis (RO) membrane from the early 1950s to the mid-2010s. The RO membrane is a critical material for desalination that is a key to solve water shortages becoming serious in many places of the world. The authors conducted in-depth field studies as well as analyses of rich archival data to demonstrate how researchers, engineers, managers, entrepreneurs, and policymakers interacted each other for this material innovation to be realized. A series of historical analyses in this book uncovered that initial government supports, strategic niche markets, emergence of breakthrough technology, and company-specific rationales played significant roles for companies to overcome four types of uncertainty, technological, market, competition, and social/organizational ones, and enabled the companies to persistently invest in the development and commercialization of the RO membrane. This book depicts that innovation does not arise on a sudden, but that it is actualized through long lasting process with turns and twists, which is driven by many non-economic rationales beyond economic motives.
Mechanisms of Arsenic Toxicity and Tolerance in Plants
by Masayuki Fujita Mirza Hasanuzzaman Kamrun NaharArsenic is likely the most talked-about metalloid in the modern world because of its toxic effects on both animal and plants. Further, arsenic pollution is now producing negative impacts on food security, especially in many south Asian countries. Since plants are a major food source, their adaptation to As-rich environments is essential, as is being informed about recent findings on multifarious aspects of the mechanisms of arsenic toxicity and tolerance in plants. Although numerous research works and review articles have been published in journals, annual reviews and as book chapters, to date there has been no comprehensive book on this topic.This book contains 19 informative chapters on arsenic chemistry, plant uptake, toxicity and tolerance mechanisms, as well as approaches to mitigation. Readers will be introduced to the latest findings on plant responses to arsenic toxicity, various tolerance mechanisms, and remediation techniques. As such, the book offers a timely and valuable resource for a broad audience, including plant scientists, soil scientists, environmental scientists, agronomists, botanists and molecular biologists.
Mechanisms of Forest Ecosystems Sustainability in a Changing Climate: Complete Triad of Ecological Monitoring
by Erland G. KolomytsThe author's working concept of geo-ecological monitoring is presented. For the first time, the full triad of monitoring in its classical definition is considered: "observation (state assessment) – control (prediction) – management (adaptation, feedback, regulation)". The strategic goal of described monitoring research is to reveal the environmental otential of sustainablility of forest ecosystems in the context of modern global warming. The monograph expounds the main statements of author’s topo-ecological predictive concept: “Global Changes on the Local Level”, as a basis of ground bio-ecological and geosystem monitoring of natural ecosystems under global anthropogenic climatic changes. This concept makes it possible to carry out local empirical simulation of the regional bioclimatic trend and thereby reveal the mechanisms of transmission of global and regional climate signals to the local level. On the example of the Volga River basin, predictive empirical-statistical models of the carbon balance of forest ecosytems are presented under conditions of a changing climate. The carbon content in various pools of boreal and nemoral forests were calculated. The global climate models give prognostic estimates of the components of them carbon balance. A quantitative assessment of the ecological resources of forest formations that provide the environment sustainability through mechanisms of regulation of the carbon cycle is given. The adaptation of forest ecosystems to climate change is described through the calculated parameters of their functional sustainability.
Mechanized Tunnelling in Urban Areas: Design methodology and construction control
by Piergiorgio Grasso Vittorio Guglielmetti Ashraf Mahtab Shulin XuInternationally, the mechanized excavation of tunnels has intensified in the last two decades, as the number of tunnels being constructed for subways and railway underpasses increases. The subject of mechanized tunnelling in urban areas has not previously received the attention that it deserves, despite there being specific hazards associated with the construction of tunnels in metropolitan areas, including poor ground conditions, water tables higher than the level of tunnels, and subsidence leading to damage to the existing structures on the surface. The application of technologies for achieving the stability of the tunnel and for minimizing surface settlement is described in this book. Accurate characterization of the ground; rigorous assessment and management of risk from design to maintenance; the correct choice of a tunnel boring machine and a plan for the advancement of the tunnel; specific excavation procedures and real-time monitoring of excavation parameters are all discussed in this thorough work.

Thanks to a healthy balance of theory and practical findings, the book offers a timely snapshot for the research and industrial communities alike, as well as a bridge to facilitate communication and collaboration between the two groups.
Media Reform and the Climate Emergency: Rethinking Communication in the Struggle for a Sustainable Future
by David ParkAward-winning author David J. Park argues that the battle against global warming is also a fight for media reform. With his new book Media Reform and the Climate Emergency: Rethinking Communication in the Struggle for a Sustainable World, he critically examines how advertising, the digital infrastructure, and journalism advance the climate emergency and lays out a path of reform to help create a more sustainable world. The production and consumption of goods and services within consumer societies lead to unsustainable greenhouse gas emissions, and Park finds that much of mass communication is either dependent upon or closely tied to the success of this social organization. As a result, he suggests successful environmental movements creatively dismantle or reform institutional infrastructures that extend the planetary global warming crisis and the unsustainable consumption of nature. Communication policies and industries are part of these infrastructures. Advertising evolved to propel a new consumer society that would encourage the over-consumption of goods and services with harmful and unsustainable production processes. Our digital infrastructure is largely premised upon the surveillance of online consumer habits and preferences, with the goal to create individualized messages to more effectively persuade people to increase their consumption habits. Much of commercial journalism resists the drastic and immediate regulatory changes necessary to address the worst aspects of this crisis. This is because so many of the needed changes challenge the media’s source of income, their libertarian philosophy, and the general status quo, which is preferred by elites. Bound to foster conversations among scholars, activists, politicians, and those who work in the communication industries, this book rethinks mass communication and highlights how immediate reform is needed in the struggle for a sustainable planet.
Media Research on Climate Change: Where have we been and where are we heading?
by Ulrika Olausson and Peter BerglezResearch on media coverage of climate change, as a particular subfield of environmental communication research, has proliferated over the past decade. This book sets out to consider what conclusions can be drawn in light of the existing body of work, what lessons can be learnt, what are the challenges to be met, and what are the directions to be taken in order to further develop media research on climate change. The mixture of articles in this volume serve well to illustrate the range of empirical, theoretical, and methodological approaches subsumed under the broad heading of "media studies on climate change." Some contributions focus on the past—how the subfield has developed and what we can learn from that—and some look toward the future. Either way, all the authors share the ambition to suggest important avenues of research, be they centered on media, context, applicability of results, or theoretical advancement. As such they make a valuable contribution to identifying important directions for future research on the role of the media in communicating climate change. This book was previously published as a special issue of Environmental Communication.
