Buch. Condizione: Neu. Neuware - There has been a great upsurge in interest in light microscopy in recent years due to the advent of a number of significant advances in microscopy, one of the most important of which is confocal microscopy. Confocal microscopy has now become an important research tool, with a large number of new…fluorescent dyes becoming available in the past few years, for probing your pet structure or molecule within fixed or living cell or tissue sampies. Many of the people interested in using confocal microscopy to further their research do not have a background in microscopy or even cell biology and so not only do they find considerable difficulty in obtaining satisfactory results with a confocal microscope, but they may be mislead by how data is being presented. This book is intended to teach you the basic concepts ofmicroscopy, fluorescence, digital imaging and the principles of confocal microscopy so that you may take full advantage ofthe excellent confocal microscopes now available. This book is also an excellent reference source for information related to confocal microscopy for both beginners and the more advanced users. For example, do you need to know the optimal pinhole size for a 63x 1. 4 NA lens Do you need to know the fluorescence emission spectrum of Alexa 568 Access to the wealth of practical information in this book is made easier by using both the detailed index and the extensive glossary.

Buch. Condizione: Neu. Neuware - Remote Sensing image analysis is mostly done using only spectral information on a pixel by pixel basis. Information captured in neighbouring cells, or information about patterns surrounding the pixel of interest often provides useful supplementary information. This book presents a wide range of i…nnovative and advanced image processing methods for including spatial information, captured by neighbouring pixels in remotely sensed images, to improve image interpretation or image classification. Presented methods include different types of variogram analysis, various methods for texture quantification, smart kernel operators, pattern recognition techniques, image segmentation methods, sub-pixel methods, wavelets and advanced spectral mixture analysis techniques. Apart from explaining the working methods in detail a wide range of applications is presented covering land cover and land use mapping, environmental applications such as heavy metal pollution, urban mapping and geological applications to detect hydrocarbon seeps. The book is meant for professionals, PhD students and graduates who use remote sensing image analysis, image interpretation and image classification in their work related to disciplines such as geography, geology, botany, ecology, forestry, cartography, soil science, engineering and urban and regional planning.

Buch. Condizione: Neu. Neuware - In the last few years, increasing effort has been devoted to better define the characteristics of tissue damage occurring outside MRI-visible lesions in patients with multiple sclerosis (MS) and, as a consequence, to improve our understanding of the disease pathobiology and of the mechanisms lead…ing to the accumulation of irreversible disability. This book provides an updated review of the results obtained by leading research groups in this field. The potential clinical applications of what has been shown so far, as well as the areas for future research in the study of normal-appearing white and gray matter damage in MS are extensively discussed, making this book a valuable tool for clinical neurologists who are involved in the daily-life care of MS patients and for neuroscientists involved in MS research.

Buch. Condizione: Neu. Neuware - Many organizations have an urgent need of mining their multiple databases inherently distributed in branches (distributed data). In particular, as the Web is rapidly becoming an information flood, individuals and organizations can take into account low-cost information and knowledge on the Intern…et when making decisions. How to efficiently identify quality knowledge from different data sources has become a significant challenge. This challenge has attracted a great many researchers including the au thors who have developed a local pattern analysis, a new strategy for dis covering some kinds of potentially useful patterns that cannot be mined in traditional multi-database mining techniques. Local pattern analysis deliv ers high-performance pattern discovery from multiple databases. There has been considerable progress made on multi-database mining in such areas as hierarchical meta-learning, collective mining, database classification, and pe culiarity discovery. While these techniques continue to be future topics of interest concerning multi-database mining, this book focuses on these inter esting issues under the framework of local pattern analysis. The book is intended for researchers and students in data mining, dis tributed data analysis, machine learning, and anyone else who is interested in multi-database mining. It is also appropriate for use as a text supplement for broader courses that might also involve knowledge discovery in databases and data mining.

Taschenbuch. Condizione: Neu. Neuware - I was a Medical Student in 1966 when the Millis Report on the training of the generalist physician was published,de ning the concept of primary care. According to the Report, the primary provider has four major responsib- ities or roles. The rst role is that of initial contact care of the…undiffer- tiated patient. The second is to provide comprehensive care based on the belief that the primary provider should be able to manage the overwhe- ing majority of problems with which patients present. Equally important is the third role-continuity and coordination of care within the health care system. Finally,the primary provider is responsible for demonstrating le- ership in the community. This Report's description of a primary provider seems as relevant today as it was when it was written. In 1994,the Institute of Medicine's assessment of primary care added the responsibility of family and community integration of care to the Millis Report description. Without question there are many challenges to a contemporary imp- mentation of this comprehensive description of primary care, beginning with the level of individual patients who so often suffer from complex pr- lems, such as mental disorders and obesity. Treating these conditions in a brief primary care visit is dif cult. At the level of the larger system, re- bursement is often inadequate and can represent policies that are uns- portive of primary care, such as those that compromise payment for preventive services that help patients to quit smoking or lose weight.; Despite a well publicized shift away from the traditional family structure, the family remains the most basic relational unit in society and the physician's most potent ally. A family orientation in health care can provide a wider understanding of illness and broader range of solutions than the classic biomedical model. Family-Oriented Primary Care: A Manual for Medical Providers offers practical guidance for the physician who would like to take greater advantage of this resource. The result is a readable guide, structured around step by step protocols that are vividly illustrated with case studies drawn from the authors' extensive collaboration at the University of Rochester School of Medicine. The preliminary chapters give a common sense grounding to family systems theory, family research, and family assessment. The family conference is carefully examined with step-by-step instructions on when and how to call and conduct one. The majority of the book offers practical guidelines for family oriented approaches to transitional events in the life cycle, such as pregnancy or nursing home placement, as well as specific medical problems, such as chronic illness and somatization of the family systems approach in the office or in the hospital. This manual is an indispensable and unique resource for all primary care physicians and residents as well as nurses, family therapists, social workers and other members of the 'helping professions.'.

Buch. Condizione: Neu. Neuware - During the last 20 years interest in high-resolution x-ray diffractometry and reflectivity has grown as a result of the development of the semiconductor industry and the increasing interest in material research of thin layers of magnetic, organic, and other materials. For example, optoelectronics… requires a subsequent epitaxy of thin layers of different semiconductor materials. Here, the individuallayer thicknesses are scaled down to a few atomic layers in order to exploit quantum effects. For reasons of electronic and optical confinement, these thin layers are embedded within much thicker cladding layers or stacks of multilayers of slightly different chemical composition. It is evident that the interface quality of those quantum weHs is quite important for the function of devices. Thin metallic layers often show magnetic properties which do not ap pear for thick layers or in bulk material. The investigation of the mutual interaction of magnetic and non-magnetic layers leads to the discovery of colossal magnetoresistance, for example. This property is strongly related to the thickness and interface roughness of covered layers.

Buch. Condizione: Neu. Neuware - Our work began where the greatest classical morphologists left off; their best work was the start of ours. As our work progressed, the rigidity of basic, previous embryological principles was broken down as scientific knowledge advanced. At the same time, the molecular, biological characterizatio…n of the cell surface receptor systems progressed enormously with the invention of numerous monoclonal antibodies. Thus, thymology became once again very important because the thymus is the first and central organ of the human immunological system. Then, the question of immuno-neuroendocrine regulation arose and has only been partially answered. Our book seeks to explore what has not been explored. The topic of thymic epithelial cells is a unique one and has never been explored in any previous book as it is explored in this one.Only a handful of great thymologists remain in the world today, especially after the great loss the medical community suffered with the passing of Dr. Good, the list includes but is not limited to: Dr. Ritter and Dr. Kendall in England, Dr. Savino in Brazil, Dr. Dardenne in France, Dr. von Gaudecker in Germany, a few others in Belgium and Holland, and it is our hope that Dr. Bodey is among them. Nonetheless, a book on the thymus has not been written in the last five years and a book such as this one has never been. This book is based on a 30-year period of research and includes references from a broad range of sources spanning the globe and all sources, even those that were the beginning of thymic research. The book, thus, is uniquely well rounded, more so that previous works.

Buch. Condizione: Neu. Neuware - Have you ever wondered where the safety factors come from Why is it that deterministic analysis has reached a very sophisticated level, but in the end empirical factors are still needed Is there a way to select them, rather than assigning them arbitrarily as is often done This book clearly shows…that safety factors are closely related with the reliability of structures, giving yet another demonstration of Albert Einstein's maxim that 'It is incomprehensible that Nature is comprehensible'. The book shows that the safety factors are much more comprehensible if they are seen in a probabilistic context. Several definitions of the safety factors are given, analytical results on insightful numbers are presented, nonprobabilistic safety factors are shown, as well as their estimates derived by the inequalities of Bienayme, Markov, Chebushev and Camp-Meidell. A special chapter is devoted to important contributions by Japanese experts. This volume will help to critically re-think the issue of safety factors, which can create a false feeling of security. The deterministic paradigm can be enhanced by incorporating probabilistic concepts wisely where they are needed without treating all variables as probabilistic ones. The book shows that there is a need of their integration rather than separation. This book is intended for engineers, graduate students, lecturers and researchers.

Buch. Condizione: Neu. Neuware - In the first, 1986, edition of this book, inverse problems in vibration were interpreted strictly: problems concerning the reconstruction of a unique, undamped vibrating system, of a specified type, from specified vibratory behaviour, particularly specified natural frequencies and/or natural mode… shapes. In this new edition the scope of the book has been widened to include topics such as isospectral systems- families of systems which all exhibit some specified behaviour; applications of the concept of Toda flow; new, non-classical approaches to inverse Sturm-Liouville problems; qualitative properties of the modes of some finite element models; damage identification.With its emphasis on analysis, on qualitative results, rather than on computation, the book will appeal to researchers in vibration theory, matrix analysis, differential and integral equations, matrix analysis, non-destructive testing, modal analysis, vibration isolation, etc. 'This book is a necessary addition to the library of engineers and mathematicians working in vibration theory.'

Buch. Condizione: Neu. Neuware - Biological nitrogen fixation provides more than 50% of the total annual input of the essential element nitrogen to world agriculture. Thus, it is of immense agronomic importance and critical to food supplies, particularly in developing countries. This book, with chapters authored by international…ly renowned experts, provides a comprehensive and detailed account of the fascinating history of the process - including the surprising discoveries of molybdenum-independent nitrogenases and superoxide-dependent nitrogenase; a review of Man's attempts to emulate the biological process - most successfully with the commercially dominant Haber-Bosch process; and the current state of the understanding art with respect to the enzymes - called nitrogenases - responsible for biological nitrogen fixation. The initial chapters use a historical approach to the biological and industrial processes, followed by an overview of assay methodologies. The next set of chapters focuses on the classical enzyme, the molybdenum nitrogenase, and details its biosynthesis, structure, composition, and mechanism of action as well as detailing both how variants of its two component proteins are constructed by recombinant DNA technology and how computational techniques are being applied. The sophisticated chemical modelling of the metal-containing clusters in the enzyme is reviewed next, followed by a description of the two molybdenum-independent nitrogenases - first, the vanadium-containing enzyme and then the iron-only nitrogenase - together with some thoughts as to why they exist! Then follows an up-to-date treatment of the clearly 'non-classical' properties of the superoxide-dependent nitrogenase, which more closely resembles molybdenum-containing hydroxylases and related enzymes, like nitrate reductase, that it does the other nitrogenases. Each chapter contains an extensive list of references. This book is the self-contained first volume of a comprehensive seven-volumeseries. No other available work provides the up-to-date and in-depth coverage of this series and this volume. This book is intended to serve as an indispensable reference work for all scientists working in this area, including agriculture and the closely related metals-in-biology area; to assist students to enter this challenging area of research; and to provide science administrators easy access to vital relevant information.

Buch. Condizione: Neu. Neuware - Mobility is perhaps the most important market and technological trend within information and communication technology. With the advent of new mobile infrastructures providing higher bandwidth and constant connection to the network from virtually everywhere, the way people use information resource…s is predicted to be radically transformed. Over the last years, a new breed of information systems, referred to as mCommerce systems or mobile information systems, has appeared to address this emerging situation. In 2000, the IFIP 8.1 WG decided to look into establishing a task group to look closer at this area, and the idea was adopted and extended by IFIP TC8 the following year. After the arrangement of several workshop, this task group has been the driving force behind the arrangement of MOBIS (IFIP TC 8 Working Conference on Mobile Information systems) held in Oslo, Norway, 15-17 September 2004. The objective of the working conference was to provide a forum for researchers and practitioners interested in planning, analysis, design, construction, modification, implementation, utilization, evaluation, and management of mobile information systems to meet, and exchange research ideas and results. Specifically, we tried to use the working conference to - Clarify differences and similarities between the development of mobile vs. more traditional information systems - Investigate organizational impact of mobile information systems - Investigate mobile commerce applications combined with the advantages of mobile communications technologies X Mobile Information Systems - Evaluate existing and newly developed approaches for analysis, design, implementation, and evolution of mobile information systems.

Buch. Condizione: Neu. Neuware - This monograph is planned to provide the application of the soliton theory to solve certain practical problems selected from the fields of solid mechanics, fluid mechanics and biomechanics. The work is based mainly on the authors' research carried out at their home institutes, and on some specifi…ed, significant results existing in the published literature. The methodology to study a given evolution equation is to seek the waves of permanent form, to test whether it possesses any symmetry properties, and whether it is stable and solitonic in nature. Students of physics, applied mathematics, and engineering are usually exposed to various branches of nonlinear mechanics, especially to the soliton theory. The soliton is regarded as an entity, a quasi-particle, which conserves its character and interacts with the surroundings and other solitons as a particle. It is related to a strange phenomenon, which consists in the propagation of certain waves without attenuation in dissipative media. This phenomenon has been known for about 200 years (it was described, for example, by the Joule Verne's novel Les histoires de Jean Marie Cabidoulin, Éd. Hetzel), but its detailed quantitative description became possible only in the last 30 years due to the exceptional development of computers. The discovery of the physical soliton is attributed to John Scott Russell. In 1834, Russell was observing a boat being drawn along a narrow channel by a pair of horses.

Taschenbuch. Condizione: Neu. Neuware - As the frequency of communication systems increases and the dimensions of transistors are reduced, more and more stringent performance requirements are placed on analog circuits. This is a trend that is bound to continue for the foreseeable future and while it does, understanding performan…ce trade-offs will constitute a vital part of the analog design process. It is the insight and intuition obtained from a fundamental understanding of performance conflicts and trade-offs, that ultimately provides the designer with the basic tools necessary for effective and creative analog design. Trade-offs in Analog Circuit Design , which is devoted to the understanding of trade-offs in analog design, is quite unique in that it draws together fundamental material from, and identifies interrelationships within, a number of key analog circuits. The book covers ten subject areas: Design methodology, Technology, General Performance, Filters, Switched Circuits, Oscillators, Data Converters, Transceivers, Neural Processing, and Analog CAD. Within these subject areas it deals with a wide diversity of trade-offs ranging from frequency-dynamic range and power, gain-bandwidth, speed-dynamic range and phase noise, to tradeoffs in design for manufacture and IC layout. The book has by far transcended its original scope and has become both a designer's companion as well as a graduate textbook. An important feature of this book is that it promotes an intuitive approach to understanding analog circuits by explaining fundamental relationships and, in many cases, providing practical illustrative examples to demonstrate the inherent basic interrelationships and trade-offs. Trade-offs in Analog Circuit Design draws together 34 contributions from some of the world's most eminent analog circuits-and-systems designers to provide, for the first time, a comprehensive text devoted to a very important and timely approach to analog circuit design.

Buch. Condizione: Neu. Neuware - The Indian Society of Genetics and Plant Breeding was established in 1941 in recognition of the growing contribution of improved crop varieties to the country's agriculture. Scientific plant breeding had started inIndia soon after the rediscovery of Mendel's laws of heredity. The Indian Agricultu…ral Research Institute set up in 1905 and a number of Agricultural Colleges in different parts of the country carried out some of the earliest work mostly inthe form of pure-line selections. In subsequent years, hybridization programmes in crops like wheat, rice, oilseeds, grain legumes, sugarcane and cotton yielded a large number of improved cultivars with significantly higher yields. A turning point came in the 1960s with the development of hybrids in several crops including inter-specific hybrids in cotton. And when new germplasm with dwarfing genes became available in wheat and rice from CIMMYT and IRRI, respectively,Indian plant breeders quickly incorporated these genes into the genetic background of the country's widely grown varieties with excellent grain quality and other desirable traits. This was to mark the beginning of modem agriculture in India as more and more varieties were developed, characterized by a high harvest index and response to modem farm inputs like the inorganic fertilizers . India's green revolution which has led to major surpluses offood grains and othercommodities like sugar and cotton has been made possible by the work of one of the largest groups of plant breeders working in a coordinated network.

Buch. Condizione: Neu. Neuware - Mesoscopic physics deals with effects at submicron and nanoscales where the conventional wisdom of macroscopic averaging is no longer applicable. A wide variety of new devices have recently evolved, all extremely promising for major novel directions in technology, including carbon nanotubes, ball…istic quantum dots, hybrid mesoscopic junctions made of different type of normal, superconducting and ferromagnetic materials. This, in turn, demands a profound understanding of fundamental physical phenomena on mesoscopic scales. As a result, the forefront of fundamental research in condensed matter has been moved to the areas where the interplay between electron-electron interactions and quantum interference of phase-coherent electrons scattered by impurities and/or boundaries is the key to such understanding. An understanding of decoherence as well as other effects of the interactions is crucial for developing future electronic, photonic and spintronic devices, including the element base for quantum computation.

Buch. Condizione: Neu. Neuware - Most recent publications on spin-related phenomena focus on technological aspects of spin-dependent transport, with emphasis on the specific needs of spintronics. The present publication targets rather fundamental problems related to the physics of spin in solids, such as: (1) manifestation of sp…in and orbital polarization in spectroscopy, including valence and X-ray photoemission, magneto-optics, low-energy electron scattering on the surface; (2) application of new methods for interpretation and determination of magnetic low-lying excitations in the bulk and on the surface; (3) recent progress in evaluation of different type of magnetic forces including spin-orbit and exchange interaction, with subsequent determination of anisotropy and spin-ordering structure; (4) general problems of spin-dependent transport in semiconductors and metals, such as current-caused torque effect on spins at interfaces and spin injection in quantum dot systems; (5) problems in understanding the spin-dependent trends in unconventional superconductors; (6) many-body problems in solid state physics and recent progress in evaluation of self-energy effects; (7) fabrication of new magnetic materials with pre-programmed properties based on assembly from nano-particles, etc.

Buch. Condizione: Neu. Neuware - This book examines both the potential application of electronic nose technology, and the current state of development of chemical sensors for the detection of vapours from explosives, such as those used in landmines. The two fields have developed, somewhat in parallel, over the past decade and so… one of the purposes of this workshop, on which the book is based, was to bring together scientists from the two fields in order to challenge the two communities and, mutually, stimulate both fields.It begins with a review of the basic principles of an electronic nose and explores possible ways in which the detection limit of conventional electronic nose technology can be reduced to the level required for the trace levels observed for many explosive materials. Next are reviews of the use of several different types of solid-state chemical sensors: polymer-based sensors, i.e. chemiluminescent, fluorescent and optical, to detect explosive materials; metal oxide semiconducting resistive sensors; and then electrochemical sensors. Next, different pattern recognition techniques are presented to enhance the performance of chemical sensors. Then biological systems are considered as a possible blue-print for chemical sensing. The biology can be employed either to understand the way insects locate odorant sources, or to understand the signal processing neural pathways. Next is a discussion of some of the new types of electronic noses; namely, a fast GC column with a SAW detector and a micromechanical sensor. Finally, the important issues of sampling technologies and the design of the microfluidic systems are considered. In particular, the use of pre-concentrators and solid phase micro extractors to boost the vapour concentration before it is introduced to the chemical sensor or electronic nose.
