Advances in Electromagnetic Fields in Living Systems ; Vol.4
Advances in Electromagnetic Fields in Living Systems , Volume 4 begins with fetal magnetocardiography (fMCG), a noninvasive method of detecting components of the magnetic field produced by the electrical activity of the fetal heart. FMCG is experiencing steady growth, and is expected to gain influence in diagnosing certain congenital fetal heart defects while at the same time providing optimal care for patients. FMCG provides a distinct signal, free of maternal cardiac interference, which can be detected throughout the last half of pregnancy.
Ad-hoc Networks : Fundamental Properties and Network Topologies
This book clearly demonstrates how the Medium Access Control protocols impose a limit on the level of interference in ad-hoc networks. It has been shown that interference is upper bounded, and a new accurate method for the estimation of interference power statistics in ad-hoc and sensor networks is introduced here. Furthermore, this volume shows how multi-hop traffic affects the capacity of the network. In multi-hop and ad-hoc networks there is a trade-off between the network size and the maximum input bit rate possible per node. Large ad-hoc or sensor networks, consisting of thousands of nodes, can only support low bit-rate applications.
Liquid separations with membranes : An introduction to barrier interference
On the level of a textbook a self-consistent approach to liquid separations with membranes is presented, contrasting equilibrium separations with the rate-controlling effects of barrier interference on mass transfer. As a corollary objective, an effort is made to observe context, factual and historical, when introducing concepts and applications of membrane separation science. Ordering principle is the formal structure of mass transfer across barriers, being construed of a driving force (allocated to the condition of the mixtures to be separated) and a barrier permeability (holding the keys to membrane selectivity). The membranes, by this approach, appear by way of the mass transport demands which they are to meet, or else by way of the separation effects which they inspire.
Laser Spectroscopy : Vol.2 Experimental Techniques
Keeping abreast of the latest techniques and applications, this new edition of the standard reference and graduate text on laser spectroscopy has been completely revised and expanded. While the general concept is unchanged, the new edition features a broad array of new material, e.g. frequency doubling in external cavities, reliable cw-parametric oscillators, tunable narrow-band UV sources, more sensitive detection techniques, tunable femtosecond and sub-femtosecond lasers (X-ray region and the attosecond range), control of atomic and molecular excitations, frequency combs able to synchronize independent femtosecond lasers, coherent matter waves, and still more applications in chemical analysis, medical diagnostics, and engineering.

Biophotonics
More profound understanding of the nature of light and light-matter interactions in biology has enabled many applications in the biology and medical fields. So a new discipline is born, namely biophotonics. The aim of this book is to review the current state-of-the-art of the field by means of authoritative chapters written by the world leaders of the respective fields. Biosensors, biochips, optical tomography, optical microsurgery, photodynamics therapy, bioactivation of gene, photobiology of skin, and nanobiophotonics are each introduced and recent advances presented. This book will be useful not only to physicians, biologists, physicists, chemists, materials scientists, and engineers but also to graduate students who are interested in these rapidly developing fields.
Biogeochemistry of Trace Elements in Arid Environments
Global warming has worsened the water resource crisis in many arid zones worldwide, from Africa to Asia, affecting millions of people and putting them at risk of hunger. Effective management of arid zone resources, including understanding the risks of toxic trace and heavy elements to humans, coupled with the need to produce more food to feed the world’s growing population, has thus become increasingly important. This very timely book, the only one of its kind on the market, fills the gap of our knowledge of trace elements in these regions. This book begins by introducing the nature and properties of arid zone soil, followed by an updated overview and comprehensive coverage of the major aspects of the trace elements and heavy metals of most concern in the world’s arid and semi-arid soils. These aspects include: - content and distribution - solution chemistry - solid-phase chemistry - selective sequential dissolution techniques - transfer fluxes - bioavailability - pollution and remediation In order to illustrate the themes, a comprehensive and focused case study on transfer fluxes of trace elements in Israeli arid soils is presented. Finally it closes with the global perspectives on anthropogenic interferences in the natural trace elements’ distribution.
Beyond Kyoto : A new global climate certificate system : Continuing Kyoto commitsments or a global ´Cap and Trade´ scheme for a sustainable climate policy?
This book shows how humankind can ‘prevent dangerous interference with the c- mate system’ without dangerous interference with the global economic system. In the two underlying studies on behalf of the Ministry of Environment and Transport of i the German federal state of Baden-Württemberg, the results have been elaborated through scientific evaluation of different climate protection systems and intensive developmental work on an efficient climate protection system. The results will be presented in nine chapters according to the following nine basic R&D steps: 1. Quantifying the ‘ultimate climate objective’ of the world community in order ‘to prevent dangerous interference with the climate system,’ thus achieving climate sustainability; 2. Development of a comprehensive standard system for evaluating the prospect of success for different climate protection systems; 3. Based on this scientific standard system, evaluation of the current Kyoto system and of the most important proposals for ‘incremental regime evolution’ of the Kyoto system. Unfortunately, it must be noted that these systems are incapable of achi- ing climate sustainability; 4. Evaluating three proposals for ‘structural regime change’ of the Kyoto system. Following this objective evaluation process and numeric comparison of the diff- ent proposals, 5. Description of the eight basic elements of GCCS and its in-depth ‘critical asse- ment;’ 6.
Adsorption and Diffusion
Molecular Sieves - Science and Technology covers, in a comprehensive manner, the science and technology of zeolites and all related microporous and mesoporous materials. Authored by renowned experts, the contributions to this handbook-like series are grouped together topically in such a way that each volume deals with a specific sub-field. Volume 7 is treating fundamentals and analyses of adsorption and diffusion in zeolites including single-file diffusion, i.e. phenomena of basic importance, especially with respect to separation processes and catalysis. Various methods of measuring adsorption and diffusion are described and discussed, i.e. techniques such as chromatographic, gravimetric and barometric uptake and desorption, nuclear magnetic resonance, infrared spectroscopy, interference microscopy, neutron scattering, frequency response as well as proton profiling.
Adaptive Techniques for Mixed Signal System on Chip
Adaptive Techniques for Mixed Signal Sytem on Chip discusses the concept of adaptation in the context of analog and mixed signal design along with different adaptive architectures used to control any system parameter. The first part of the book gives an overview of the different elements that are normally used in adaptive designs including tunable elements as well as voltage, current, and time references with an emphasis on the circuit design of specific blocks such as voltage-controlled transconductors, offset comparators, and a novel technique for accurate implementation of on chip resistors. While the first part of the book addresses adaptive techniques at the circuit and block levels, the second part discusses adaptive equalization architectures employed to minimize the impact of ISI (Intersymbol Interference) on the quality of received data in high-speed wire line transceivers. It presents the implementation of a 125Mbps transceiver operating over a variable length of Category 5 (CAT-5) Ethernet cable as an example of adaptive equalizers.
