There can be no doubt that alkaline phosphatase is one of the most extensively in vestigated of all enzymes. This has resulted from the ubiquity of its distribution, and from the ease and sensitivity with which its activity can be measured. Unfortunately, these wide-ranging but often superficial experimental studies have been followed up by intensive and systematic investigations in only a few limited areas of the biochemistry and chemical pathology of alkaline phosphatase. The result has been the accumulation of a scientific literature of intimidating proportions, and the inevitable rediscovery of already known facts about the enzyme. Scientists are taught early in their careers that, in the words of Sir John Herschel, "Hasty generalization is the bane of science. " Nevertheless, moments arrive in all spheres of scientific activity when generalization becomes essential, to codify and to select from the mass of data already accumulated, and to provide starting points for new developments and new lines of investigation. This is especially true in a field such as alkaline phosphatase research, in which very real dangers exist that the seeds of fundamental understanding will be lost amidst an unexamined harvest of empirical observations. The history of the study of alkaline phosphatase provides several instances when valuable generalizations have emerged. Occasionally, the conclusions drawn on the basis of available evidence were wrong; more frequently, they have stood the test of further experimentation, and always, they have provided new insights into the nature and proper ties of this enzyme."
This book provides a state-of-the-art compendium on the role of proteoglycans and glycosaminoglycans during development and in cancer. It also suggests directions for novel therapeutic and biotechnological applications in stem cell biology. Proteoglycans and glycosaminoglycans, as part of the extracellular matrix, are multifunctional modulators of growth factor, cytokine, integrin and morphogen signaling, which determine both self-renewal, senescence and/or differentiation of stem cells during development. Since proteoglycans modulate cell adhesion and migration they are important organizers of the extracellular matrix within the proper stem cell niche. A malfunctioning of proteoglycans and glycosaminoglycans contributes to the cancer stem cell phenotype, which is linked to therapeutic resistance and recurrence in malignant disease. This book is essential reading for anyone interested in the extracellular matrix and its role in development. The series Biology of Extracellular Matrix is published in collaboration with the American Society for Matrix Biology.
This thesis builds on recent innovations in multi-phase emulsion droplet design to demonstrate that emulsion morphologies enable a useful variety of dynamic optical phenomena. Despite the highly dynamic nature of fluid morphologies and their utility for stimuli-responsive, dynamic optical materials and devices, fluid matter is underrepresented in optical technology. Using bi-phase emulsion droplets as refractive micro-optical components, this thesis realizes micro-scale fluid compound lenses with optical properties that vary in response to changes in chemical concentrations, structured illumination, and thermal gradients. Theoretical considerations of emulsions as optical components are used to explain a previously unrecognized total internal reflection-enabled light interference phenomenon in emulsion droplets that results in rich structural coloration. While this work is focused on the fundamental optics of emulsion droplets, it also facilitates the use of light-emitting emulsion morphologies as chemo-optical transducers for early-stage food-borne pathogen detection. This thesis beautifully demonstrates the virtue of fundamental interdisciplinary exploration of unconventional material systems at the interface of optics, chemistry, and materials science, and the benefits arising from translation of the acquired knowledge into specific application scenarios.
Potentiometric Water Analysis Second Edition Derek Midgley and Kenneth Torrance, National Power plc, Technology and Environmental Centre, Leatherhead, Surrey, UK This volume is a thoroughly revised and updated version of the very successful first edition. It provides, in one single volume, a comprehensive survey of the theoretical and practical aspects of potentiometry and ion-selective electrodes applied to the analysis of water. The first part of the book describes the basic theory of electrodes, the statistical treatment of results, titrimetric methods and general guidance on procedures. Useful information is given on the types of electrodes available, together with the apparatus required for laboratory and industrial use. For this second edition, the authors include details on microprocessor-based instruments, new electrodes and techniques that have recently been developed, as well as updating the variations on established procedures and their performance characteristics. The second part of the book gives detailed analytical methods for identifying a variety of determinands. Worked examples with discussions of sources of error and likely accuracy are also included. The book is designed to give sufficiently detailed procedures so that the reader can use the methods without recourse to the primary literature. With its emphasis on the practical aspects of potentiometric water analysis, this book will be a valuable tool for analysts working in the field.
This volume compiles and discusses the fundamental and multidisciplinary knowledge on adsorption and separation processes using zeolites as adsorbents. Over the last decade, a large amount of research has been carried out for the development of zeolites as adsorbents. However, there is still a growing interest to increase the understanding of such selective adsorbents. Therefore, synthesis strategies and new approaches for developing new selective zeolite adsorbents for gas separation are presented in the first chapter. In addition, a chapter focused on adsorption characterization techniques of microporous materials is included. This will be helpful for advanced readers, since the new IUPAC recommendations for microporous characterization are not still widely employed by the zeolite community. Experimental and theoretical aspects of economically and environmentally relevant separations, which have been successfully carried out with zeolites, are discussed in detail in subsequent chapters. Finally, industrial zeolite based adsorption and separation processes as well as current perspectives for new zeolite based separations, and improvements of current technologies are presented.
The work in your hand contains three main chapters, covering the chemistry of the condensed phase in the atmosphere, first, the different forms of atmospheric waters (precipitation, fog and clouds, dew), and secondly dust, now mostly termed particulate matter and, more scientifically, atmospheric aerosol. A third section treats the gases in the atmosphere. An introductory chapter covers the roots of the term atmospheric chemistry in its relations to chemistry in general and biogeochemistry as the chemistry of the climate system. Furthermore, a brief overview of understanding chemical reactions in aqueous and gaseous phase is given. It is my aim to pay respect to all persons who studied the substances in the air, to those who made small, and to them who made giant contributions for the progress in atmospheric science. I'm not a historian who is able to present the past from a true perspective of their time - this also would not be my aim. If possible, however, I try to interpret the past - almost limited to experimental fi ndings in the nineteenth century - through current values, without dismissal of the problems and ideas of earlier scientists. In this way it is possible to draw some ideas on the historical chemical state of the air. Hence, I name this voyage critical. However, nowhere in this book it is my attention to express my criticism to colleagues and scientifi c ancestors. Great scientists too were subject to errors; doing science consists from the permanent loop observation, interpretation, conclusion, and again testing against new observation. If this volume can contribute more than to be "a nice story" on atmospheric chemistry, then hopefully it inspires the reader to more critical reading of scientifi c publications, and, not to forget the older one.
Chemometrics in Spectroscopy, Second Edition, provides the reader with the methodology crucial to apply chemometrics to real world data. It allows scientists using spectroscopic instruments to find explanations and solutions to their problems when they are confronted with unexpected and unexplained results. Unlike other books on these topics, it explains the root causes of the phenomena that lead to these results. While books on NIR spectroscopy sometimes cover basic chemometrics, they do not mention many of the advanced topics this book discusses. In addition, traditional chemometrics books do not cover spectroscopy to the point of understanding the basis for the underlying phenomena. The second edition has been expanded with 50% more content covering advances in the field that have occurred in the last 10 years, including calibration transfer, units of measure in spectroscopy, principal components, clinical data reporting, classical least squares, regression models, spectral transfer, and more.

This book aims to give state of the art in several domains of cultural heritage in which Nanosciences allow fundamental breakthrough. The first part of the book concerns nanostructured materials in ancient artifacts. Understanding their nature and formation processes bring new insight in the apprehension of technical level of ancient societies but can also inspire the design of new materials. The second part is dedicated to the understanding of materials. This crucial issue in material science today, for cultural heritage, needs to perform specific characterization techniques and technologies, but also to create tailored analytical strategies. Part three presents new methods, processes and materials at nano levels that can bring innovative solutions to conservation and restoration issues, linked with the understanding of the alteration processes involved at different scales.
Over-pumping of aquifers is a worldwide problem, mainly caused by agricultural water use. Among its consequences are the falling dry of streams and wetlands, soil subsidence, die-off of phreatophytic vegetation, saline water intrusion, increased pumping cost and loss of storage needed for drought relief. Stopping or reversing the trend requires management interventions. The North China Plain serves as an example. A management system is set up for a typical county. It contains three components: monitoring, decision support based on modelling, and implementation in the field. Besides all monitoring data, the decision support module contains an irrigation calculator, a box model, and a distributed groundwater model to project the outcomes of different water allocation scenarios. In view of grain security, a solution combines an adaptation of the cropping system with imports of surface water from the South. The Open Access book does not only describe the problem and the path to its solution. It also gives access to nine manuals concerning methods used. They include computer programs and the game Save the Water. The Chinese experience should be of considerable interest to other regions in the world which suffer from over-pumping of aquifers.
Chiral Analysis: Advances in Spectroscopy, Chromatography and Emerging Methods, Second Edition covers an important area of analytical chemistry of relevance to a wide variety of scientific professionals, including chemistry graduate students, analytical chemists, organic chemists, professionals in the pharmaceutical industry, and others with an interest in chirality and chiral analysis. This thoroughly revised second edition covers several new, important areas of chiral analysis that have emerged since the first edition. Three of the new methods provide higher sensitivity than can be realized with the current methods and are expected to become mainstream applications: cavity based methods offer vastly higher sensitivity than conventional polarimetric methods, microwave chiral detection provides unsurpassed sensitivity for identifying diastereomers, and the rotating electric field method offers a competing new approach for the separation of enantiomers. Another topic, chirality in extraterrestrial life, has not been discussed in any other book and is important for understanding the origin of life.
