Approaches in Bioremediation: The New Era of Environmental Microbiology and Nanobiotechnology (Nanotechnology in the Life Sciences)

by Ram Prasad Elisabet Aranda

Bioremediation refers to the clean‐up of pollution in soil, groundwater, surface water, and air using typically microbiological processes. It uses naturally occurring bacteria and fungi or plants to degrade, transform or detoxify hazardous substances to human health or the environment.For bioremediation to be effective, microorganisms must enzymatically attack the pollutants and convert them to harmless products. As bioremediation can be effective only where environmental conditions permit microbial growth and action, its application often involves the management of ecological factors to allow microbial growth and degradation to continue at a faster rate. Like other technologies, bioremediation has its limitations. Some contaminants, such as chlorinated organic or high aromatic hydrocarbons, are resistant to microbial attack. They are degraded either gradually or not at all, hence, it is not easy to envisage the rates of clean-up for bioremediation implementation.Bioremediation represents a field of great expansion due to the important development of new technologies. Among them, several decades on metagenomics expansion has led to the detection of autochthonous microbiota that plays a key role during transformation. Transcriptomic guides us to know the expression of key genes and proteomics allow the characterization of proteins that conduct specific reactions. In this book we show specific technologies applied in bioremediation of main interest for research in the field, with special attention on fungi, which have been poorly studied microorganisms. Finally, new approaches in the field, such as CRISPR-CAS9, are also discussed. Lastly, it introduces management strategies, such as bioremediation application for managing affected environment and bioremediation approaches. Examples of successful bioremediation applications are illustrated in radionuclide entrapment and retardation, soil stabilization and remediation of polycyclic aromatic hydrocarbons, phenols, plastics or fluorinated compounds. Other emerging bioremediation methods include electro bioremediation, microbe-availed phytoremediation, genetic recombinant technologies in enhancing plants in accumulation of inorganic metals, and metalloids as well as degradation of organic pollutants, protein-metabolic engineering to increase bioremediation efficiency, including nanotechnology applications are also discussed.

Approaches to Economic Geography: Towards a geographical political economy (Regions and Cities)

by Ray Hudson

The last four decades have seen major changes in the global economy, with the collapse of communism and the spread of capitalism into parts of the world from which it had previously been excluded. Beginning with a grounding in Marxian political economy, this book explores a range of new ideas as to what economic geography can offer as it intersects with public policy and planning in the new globalised economy. Approaches to Economic Geography draws together the formidable work of Ray Hudson into an authoritative collection, offering a unique approach to the understanding of the changing geographies of the global economy. With chapters covering subjects ranging from uneven development to social economy, this volume explores how a range of perspectives, including evolutionary and institutional approaches, can further elucidate how such economies and their geographies are reproduced. Subsequent chapters argue that greater attention must be given to the relationships between the economy and nature, and that more consideration needs to be given to the growing significance of illegal activities in the economy. The book will be of interest to students studying economic geography as well as researchers and policy makers that recognise the importance of the relationships between economy and geography as we move towards a sustainable future economy and society.

Approaches to Study Living Foraminifera: Collection, Maintenance and Experimentation (Environmental Science and Engineering)

by Hiroshi Kitazato Joan M. Bernhard

Foraminiferal cultures now serve as tools for researching biological, environmental, and geological topics. However, the biological backgrounds, in particular the natural histories of foraminifera, largely remain unclear. It is also true that the different techniques used in different subdisciplines are a setback to fully understanding the subject. Taken together, these factors prevent progress in experimental approaches to foraminiferal studies. This book aims to share and exchange knowledge between researchers from different subdisciplines, and the book should interest not only foraminiferal researchers but also scientists who are working with marine organisms to explore questions in relation to biology, geology, and oceanography.

Approaching Sovereignty over the Diaoyu Islands: From the Perspectives of Ryukyu and Okinawa (China Academic Library)

by Tin Wong

This book discusses the sovereignty over the Diaoyu Islands from the perspectives of Ryukyu and Okinawa. Written in chronological order, the book has 13 chapters featuring 121 documents and maps. The first 12 chapters explain, based on detailed historical facts on the Diaoyu Islands, the rise and decline of the Ryukyu Kingdom and the historical roles of China, Japan, and the United States in the history of the kingdom. The final chapter is an overview of the Sino-Ryukyuan, Japan-Ryukyuan and US-Ryukyuan relations, and further clarifies the issue of ownership of the Diaoyu Islands and their strategic position. The book demonstrates that Ryukyu did not have sovereignty over the Diaoyu Islands, refutes Japan’s claim that these islands were a part of the Ryukyu Kingdom, and reveals the causes and consequences of the Sino-Japanese conflicts created by the United States. The book examines the 500-year friendship between China and Ryukyu, recounting moving stories. Lastly, citing ancient documents and more, the books proves that the Ryukyus never owned the Diaoyu Islands and that these islands belong to China.

Approaching Transnationalisms: Studies on Transnational Societies, Multicultural Contacts, and Imaginings of Home

by Brenda S. A. Yeoh Michael W. Charney

The term 'transnationalism' has gained considerable academic and popular currency despite a lack of clear definitions, in part because its overall form changes as its influence incorporates additional spheres of daily life on a variety of scales and contexts. The purpose of this volume is to bring together different perspectives on this phenomenon, using case studies that represent some of the most current thinking on 'transnationalism' in a wide range of disciplines. Central themes which this book explores include legal and economic reactions to transnational migration; the (re)negotiation of identities in the context of changing national, social and cultural identities; and the emergence of new imaginings of home and social space in transnational communities. Approaching Transnationalisms: Studies on Transnational Societies, Multicultural Contacts and Imaginings of Home foregrounds powerful transnational forces crossing the boundaries of nation-states, and at the same time, gives attention to the continued significance of the nation-state and the diversity of localized reactions to transnational challenges.

The Appropriation of Ecological Space: Agrofuels, unequal exchange and environmental load displacements (Routledge Studies in Ecological Economics)

by Kenneth Hermele

Although it is recognised that Thomas Robert Malthus was wrong when he posited a contradiction between population increase and agricultural growth, there are increasing signs that he could be proved right in the future. Perhaps Malthus was too late and too early in his prediction? He was too late, because he did not foresee the shift from land-based resources to fossil fuels, outing an end to the limits of agricultural growth, at least temporarily; and he was too early to witness that fossil fuels would come up against their own limits in terms of supply as well as in terms of global warming. This study deals with land-based resources and the role they play in the global socio-ecological metabolic regime, both now and in the future. In particular, the controversial use of agrofuels as a solution to coming scarcity is subjected to close scrutiny.

Approximate and Noisy Realization of Discrete-Time Dynamical Systems (Lecture Notes in Control and Information Sciences #Vol. 376)

by Yasumichi Hasegawa

This monograph deals with approximation and noise cancellation of dynamical systems which include linear and nonlinear input/output relations. It will be of special interest to researchers, engineers and graduate students who have specialized in ?ltering theory and system theory. From noisy or noiseless data, reductionwillbemade.Anewmethodwhichreducesnoiseormodelsinformation will be proposed. Using this method will allow model description to be treated as noise reduction or model reduction. As proof of the e?cacy, this monograph provides new results and their extensions which can also be applied to nonlinear dynamical systems. To present the e?ectiveness of our method, many actual examples of noise and model information reduction will also be provided. Using the analysis of state space approach, the model reduction problem may have become a major theme of technology after 1966 for emphasizing e?ciency in the ?elds of control, economy, numerical analysis, and others. Noise reduction problems in the analysis of noisy dynamical systems may havebecomeamajorthemeoftechnologyafter1974foremphasizinge?ciencyin control.However,thesubjectsoftheseresearcheshavebeenmainlyconcentrated in linear systems.

Approximate Global Convergence and Adaptivity for Coefficient Inverse Problems

by Larisa Beilina Michael Victor Klibanov

Approximate Global Convergence and Adaptivity for Coefficient Inverse Problems is the first book in which two new concepts of numerical solutions of multidimensional Coefficient Inverse Problems (CIPs) for a hyperbolic Partial Differential Equation (PDE) are presented: Approximate Global Convergence and the Adaptive Finite Element Method (adaptivity for brevity). Two central questions for CIPs are addressed: How to obtain a good approximations for the exact solution without any knowledge of a small neighborhood of this solution, and how to refine it given the approximation. The book also combines analytical convergence results with recipes for various numerical implementations of developed algorithms. The developed technique is applied to two types of blind experimental data, which are collected both in a laboratory and in the field. The result for the blind backscattering experimental data collected in the field addresses a real world problem of imaging of shallow explosives.

Approximate Quantum Markov Chains (SpringerBriefs in Mathematical Physics #28)

by David Sutter

This book is an introduction to quantum Markov chains and explains how this concept is connected to the question of how well a lost quantum mechanical system can be recovered from a correlated subsystem. To achieve this goal, we strengthen the data-processing inequality such that it reveals a statement about the reconstruction of lost information. The main difficulty in order to understand the behavior of quantum Markov chains arises from the fact that quantum mechanical operators do not commute in general. As a result we start by explaining two techniques of how to deal with non-commuting matrices: the spectral pinching method and complex interpolation theory. Once the reader is familiar with these techniques a novel inequality is presented that extends the celebrated Golden-Thompson inequality to arbitrarily many matrices. This inequality is the key ingredient in understanding approximate quantum Markov chains and it answers a question from matrix analysis that was open since 1973, i.e., if Lieb's triple matrix inequality can be extended to more than three matrices. Finally, we carefully discuss the properties of approximate quantum Markov chains and their implications.The book is aimed to graduate students who want to learn about approximate quantum Markov chains as well as more experienced scientists who want to enter this field. Mathematical majority is necessary, but no prior knowledge of quantum mechanics is required.

Approximation Methods in Science and Engineering

by Reza N. Jazar

Approximation Methods in Engineering and Science covers fundamental and advanced topics in three areas: Dimensional Analysis, Continued Fractions, and Stability Analysis of the Mathieu Differential Equation. Throughout the book, a strong emphasis is given to concepts and methods used in everyday calculations. Dimensional analysis is a crucial need for every engineer and scientist to be able to do experiments on scaled models and use the results in real world applications. Knowing that most nonlinear equations have no analytic solution, the power series solution is assumed to be the first approach to derive an approximate solution. However, this book will show the advantages of continued fractions and provides a systematic method to develop better approximate solutions in continued fractions. It also shows the importance of determining stability chart of the Mathieu equation and reviews and compares several approximate methods for that. The book provides the energy-rate method to study the stability of parametric differential equations that generates much better approximate solutions.

Approximation of Free-Discontinuity Problems (Lecture Notes in Mathematics #1694)

by Andrea Braides

Functionals involving both volume and surface energies have a number of applications ranging from Computer Vision to Fracture Mechanics. In order to tackle numerical and dynamical problems linked to such functionals many approximations by functionals defined on smooth functions have been proposed (using high-order singular perturbations, finite-difference or non-local energies, etc.) The purpose of this book is to present a global approach to these approximations using the theory of gamma-convergence and of special functions of bounded variation. The book is directed to PhD students and researchers in calculus of variations, interested in approximation problems with possible applications.
