Buch. Zustand: Neu. Neuware - Lo, soul! seest thou not God's purpose from the first The earth to be spann'd, connected by net-work From Passage to India! Walt Whitman, 'Leaves of Grass', 1900. The Internet is growing at a tremendous rate today. New services, such as telephony and multimedia, are being added to the pure data-delivery framework of yesterday. Such high demands on capacity could lead to a 'bandwidth-crunch' at the core wide-area network resulting in degra dation of service quality. Fortunately, technological innovations have emerged which can provide relief to the end-user to overcome the In ternet's well-known delay and bandwidth limitations. At the physical layer, a major overhaul of existing networks has been envisaged from electronic media (such as twisted-pair and cable) to optical fibers - in the wide area, in the metropolitan area, and even in the local area set tings. In order to exploit the immense bandwidth potential of the optical fiber, interesting multiplexing techniques have been developed over the years. Wavelength division multiplexing (WDM) is such a promising tech nique in which multiple channels are operated along a single fiber si multaneously, each on a different wavelength. These channels can be independently modulated to accommodate dissimilar bit rates and data formats, if so desired. Thus, WDM carves up the huge bandwidth of an optical fiber into channels whose bandwidths (1-10 Gbps) are compati ble with peak electronic processing speed.

Buch. Zustand: Neu. Neuware - Mathematical models are being increasingly used to estimate the concentrations of a wide range of substances in the environment for a variety of reasons, including government control and legislation, and risk and hazard estimation. Exposure assessment has to be performed for many types of substances, including pesticides, industrial chemicals, pollutants, accidental discharges, etc. The interpretation of the results of model equations should always bear in mind the purpose for which the model used was built in the first place. Further, models are always an abstraction of reality, requiring simplifying assumptions to keep the models within the restraints posed by computer performance and/or scientific knowledge. The present book treats the theme of modelling chemical exposure and risk in terms of four main topics: model characteristics, applications, comparison of estimated with measured concentrations, and modelling credibility.

Buch. Zustand: Neu. Neuware - This book should be of interest to scholars, researchers, students, and practitioners alike. Scholars, researchers, and students of personal relationship development will recognize in this book the first serious attempt in over 40 years to do a large-scale, longitudinal study of premarital factors that predict premarital breakup and marital quality; they should also appreciate our attempt to develop a theoretical rationale for predicted paths and to test those paths with the best available statistical tools. Practitioners-while generally not as interested in the intricacies of the statistical results-will find much that is useful to them as they help individuals and couples make decisions about their intimate relationships, their readiness for marriage, and how to increase the probability for marital success. Teachers, family life educators, premarital counselors, and clergy will find helpful our 'principles for practice,' particularly as described in Chapter 9, as they teach and counsel couples in any premarital situation. My interest in the development of relationships from premarital to marital probably began when I got married in 1972 and started to notice all of the characteristics my wife and I brought from our respective families and how our 'new beginning' as a married couple was in many ways the continuation of our premarital relationship, only more refined and more intense. My professional interest began when I did my doctoral dissertation in 198 1 on premarital predictors of early marital satisfaction (the results of that study are reported in Chapter 8).

Buch. Zustand: Neu. Neuware - Biophysical studies in the 1950ies and 1960ies led to the realization that the water permeability of certain biological membranes must be due to the presence of water transporting proteins. This hypothesis was confirmed in 1991 and 1992 with the pioneering discovery of the first molecular membrane water channel, CHIP28, by Agre and coworkers. This integral membrane protein, which is abundant in the erythrocyte membrane and in many epithelial cells, is now called aquaporin-1 or AQP1. Thus the terms water channel or aquaporin are synonymous. In July 2000 more than 200 researchers came together in Gothenburg, Sweden, for the `3rd International Conference on the Molecular Biology and Physiology of Water and Solute Transport' to discuss progress in this emerging research field. 58 different presentations from this conference are the basis for this book. Cumulatively, these 58 short chapters provide a balanced overview complementing numerous recent reviews in this field.

Buch. Zustand: Neu. Neuware - Computer models offer a means of interpreting and analyzing the dynamics of real-world systems ranging from population growth to ozone depletion and a new section on modeling in genetics. Dynamic Modeling introduces an approach to modeling that makes it a more practical, intuitive endeavor. The book enables readers to convert their understanding of a phenomenon to a computer model, and then to run the model and let it yield the inevitable dynamic consequences built into the structure of the model. Dynamic Modeling uses STELLA software to develop simulation models. Part I provides an introduction to modeling dynamic systems. Part II offers general methods for modeling. Parts III through VIII apply these methods to model real-world phenomena from chemistry, genetics, ecology, economics, and engineering. Dynamic Modeling offers a clear, approachable introduction to the modeling process, and will be of interest in any field where real problems can be illuminated by computer simulation.

Buch. Zustand: Neu. Neuware - The classification of patterns is an important area of research which is central to all pattern recognition fields, including speech, image, robotics, and data analysis. Neural networks have been used successfully in a number of these fields, but so far their application has been based on a 'black box approach', with no real understanding of how they work. In this book, Sarunas Raudys - an internationally respected researcher in the area - provides an excellent mathematical and applied introduction to how neural network classifiers work and how they should be used to optimal effect. Among the topics covered are: - Different types of neural network classifiers; - A taxonomy of pattern classification algorithms; - Performance capabilities and measurement procedures; - Which features should be extracted from raw data for the best classification results. This book will provide essential reading for anyone researching or studying relevant areas of patter n recognition (such as image processing, speech recognition, robotics, and multimedia). It will also be of interest to anyone studing or researching in applied neural networks.

Buch. Zustand: Neu. Neuware - Despite the fact that the human life of the past cannot be understood without taking into account its ecological relationships, environmental studies are often marginalised in archaeology. This is the first book that, by discussing the meaning and purpose we give to the expression `environmental archaeology', investigates the reasons for such a problem. This is achieved through the use of theoretical considerations and the aid of a number of case studies, which, by taking us from Anglo-Saxon England to pre-Columbian Venezuela, and from Classical Greece to late Antique Egypt, emphasise the potential of an integrated approach. The book is written by archaeologists with different backgrounds and is addressed to all researchers who care about the past relationship between people and the rest of Nature. Despite the complexity of some of the issues tackled, the book is written in an accessible manner and should be of interest to all students who want to understand the essence of archaeology beyond the boundary of the individual sub-disciplines.

Buch. Zustand: Neu. Neuware - The triennial International Alloy Conferences (lACs) aim at the identification and promotion of the common elements developed in the study, either experimental, phenomenological, or theoretical and computational, of materials properties across materials types, from metals to minerals. To accomplish this goal, the lACs bring together scientists from a wide spectrum of materials science including experiment, theory, modeling, and computation, incorporating a broad range of materials properties. The first lAC, lAC-I, took place in Athens, Greece, June 16-21, 1996. The present volume of proceedings contains the papers presented at IAC-2, that took place in Davos, Switzerland, August 8-13, 1999. The topics in this book fall into several themes, which suggest a number of different classification schemes. We have chosen a scheme that classifies the papers in the volume into the categories Microstructural Properties; Ordering, Kinetics and Diffusion; Magnetic Properties and Elastic Properties. We have juxtaposed apparently disparate of revealing the dynamic character approaches to similar physical processes, in the hope of the processes under consideration. We hope this will invigorate new kinds of discussion and reveal challenges and new avenues to the description and prediction of properties of materials in the solid state and the conditions that produce them.

Buch. Zustand: Neu. Neuware - This volume contains a selection of 14 articles dealing with different aspects of biomonitoring and their relation to questions of global change. During the last 10 - 15 years, vegetation changes due to various causes have been more intensively studied in biological and environmental sciences. Especially aspects of global warming lead to a great variety of tasks for vegetation science (see e.g. the articles by Grabherr, Gottfried & Pauli; Carraro, Gianoni, Mossi, KlOtzli & Walther; Walther; Defila; Stampfli & Zeiter; Rothlisberger; Burga & Perret and Moller, WUthrich & Thannheiser). The different aspects of applied biomonitoring related to (possible) environmental changes concern various ecosystems, e.g. Central European beechwoods, Insubrian evergreen broad-leaved forests, thermophilous lowland deciduous forests, dry grasslands of the lower montane belt of the Ticino Alps, alpine mountain peaks of Switzerland and Austria, Swiss alpine timberline ecotones, and high arctic tundra vegetation. The volume is divided into three parts: A. General aspects of biomonitoring (contributions by KlOtzli; Wildi and Labasch & Otte) , B. Examples of applied biomonitoring in Germany and Switzerland (articles by Hakes; Herpin, Siewers, Kreimes & Markert; Defila; Stampfli & Zeiter; Rothlisberger and Ruoss, Burga & Eschmann), and C. Aspects of global change in the Alps and in the high arctic tundra (Grabherr, Gottfried & Pauli; Burga & Perret; Carraro, Gianoni, Mossi, KlOtzli & Walther; Walther and Moller, WUthrich & Thannheiser).

Buch. Zustand: Neu. Neuware - The design of computer systems to be embedded in critical real-time applications is a complex task. Such systems must not only guarantee to meet hard real-time deadlines imposed by their physical environment, they must guarantee to do so dependably, despite both physical faults (in hardware) and design faults (in hardware or software). A fault-tolerance approach is mandatory for these guarantees to be commensurate with the safety and reliability requirements of many life- and mission-critical applications. This book explains the motivations and the results of a collaborative project', whose objective was to significantly decrease the lifecycle costs of such fault tolerant systems. The end-user companies participating in this project already deploy fault-tolerant systems in critical railway, space and nuclear-propulsion applications. However, these are proprietary systems whose architectures have been tailored to meet domain-specific requirements. This has led to very costly, inflexible, and often hardware-intensive solutions that, by the time they are developed, validated and certified for use in the field, can already be out-of-date in terms of their underlying hardware and software technology.

Buch. Zustand: Neu. Neuware - Future Directions in Postal Reform brings together leading practitioners, world-wide postal administrations, and the courier industry, as well as a number of regulators, academic economists, mailers, and lawyers, to examine some of the major policy and regulatory issues facing the postal and delivery industry. Issues addressed include international postal policy; the universal service obligation; regulation; competition, entry, and the role of scale and scope economies; the nature and role of cost analysis in postal service; productivity; interaction of law and economics; and future technologies and service standards.

Buch. Zustand: Neu. Neuware - It is an authentic privilege to have the opportunity to assemble and edit a new volume on 'Prolactin,' the first in several decades to be devoted to this fascinating hormone in all its aspects. The obvious clinical rationale for understanding prolactin (PRL) is the frequent occurrence of prolactinomas, the most common type of pituitary tumor. Fortunately, medical management of prolactinomas can be based on our under standing of the physiology of hypothalamic control of the lactotroph. Armed with this knowledge, therapies for proiactinomas are highly successful and well tolerated. Be cause of the historical and practical importance of knowledge regarding the hypothala mus-Iactotroph axis, the first chapters of this volume are dedicated to reviewing the physiology, development, and cell biology of lactotroph regulation. Chapters focusing on prolactinomas and related clinical issues follow these. PRL is the primary hormone that is responsible for 'parental care' in many verte brate species. This reproductive strategy is not unique to mammals, but it has devel oped through evolution to be the central distinguishing feature of the mammalian life cycle. Among the mammals, mice have become the most effective research species in recent years. This can be traced to the development of a wide range of methods for manipulating mouse genetics, and thereby influencing development, physiology and behavior. Mice also provide a profound illustration of the physiological challenges faced in maternity. Female mice undergo a post-partum estrous, and often are both pregnant and lactating simultaneously.

Buch. Zustand: Neu. Neuware - Mitochondria from mammalian tissues possess an elaborate system for 2+ 2+ transporting Ca across their inner membrane which consists of Ca import, 2+ via the Ca uniporter, in response to the mitochondrial membrane 2+ + potential and of Ca release by an antiport system in exchange for H + 9,23 or Na (see Fig. l) . Because the uniporter is dependent upon the external 2+ 2+ 2+ 2+ Ca concentration ([Ca ]), mitochondria accumulate Ca until the [Ca ] o o 2+ decreases to the level at which the uniporter activity balances the Ca efflux. 2+ The [Ca ] at which the uniporter and efflux activities are equal is defined o the 'setpoint' andcorresponds to values between 0.3-3µM. 2+ Figure 1.
