The central theme, which threads through the entire book, concerns computational modeling methods for water. Modeling results for pure liquid water, water near ions, water at interfaces, water in biological microsystems, and water under other types of perturbations such as laser fields are described. Connections are made throughout the book with statistical mechanical theoretical methods on the one hand and with experimental data on the other. The book is expected to be useful not only for theorists and computer analysts interested in the physical, chemical, biological and geophysical aspects of water, but also for experimentalists in these fields.
This book takes a broad and eclectic view of the water that all humanity depends upon, probing its role in human life and in the history of our planet, as well as surveying the latest scientific understanding of purification techniques and standards for the protection of water quality. The volume opens with a chapter on the role of drinking water in human life, which discusses the planet’s water resources, the quality of drinking water, water and health, the advent of water quality standards, “Green” chemistry and more. The chapter concludes by discussing the relationship of the biosphere and human civilization. Chapter Two explores the unique properties of water, the role of water in the scenario of development on Earth. Also covered is the current understanding of the importance of the isotopic composition of water, in particular the ratio of protium to deuterium, which is fundamental to life. The third chapter is devoted to Water Clusters, examining the structure, properties and formation of clusters. Also covered here is theoretical research on the interaction of water clusters with ozone, the impact of temperature on water clusters and more. Chapter Four is devoted to drinking water and factors affecting its quality. Discussion includes ecological and hygienic classification of centralized drinking water supply sources, water quality requirements, and problems and potentialities of drinking water preparation. The author introduces a new concept for supplying the population with high-quality drinking water. The fifth chapter examines the peculiarities and problems of water decontamination, with sections on chlorination, ozonation, the bactericidal effects of ultrasound and ultraviolet rays and more. Chapter Six offers a thorough exploration of the theory, means and methods of bio testing as an evaluation method for the quality of drinking water. The final chapter discusses new state standards for drinking water, as well as requirements and methods of quality control. The concluding selection relates the urgent need to measure, evaluate and protect the quality of drinking water and describes a new state standard of drinking water quality.
to arrive at some temporary consensus model or models; and to present reliable physical data pertaining to water under a range of conditions, i.e., "Dorsey revisited," albeit on a less ambitious scale. I should like to acknowledge a debt of gratitude to several of my col leagues, to Prof. D. J. G. Ives and Prof. Robert L. Kay for valuable guidance and active encouragement, to the contributors to this volume for their willing cooperation, and to my wife and daughters for the understanding shown to a husband and father who hid in his study for many an evening. My very special thanks go to Mrs. Joyce Johnson, who did all the cor respondence and much of the arduous editorial work with her usual cheerful efficiency. F.

Reflecting a rich technical and interdisciplinary exchange of ideas, Water and Life: The Unique Properties of H20 focuses on the properties of water and its interaction with life. The book develops a variety of approaches that help to illuminate ways in which to address deeper questions with respect to the nature of the universe and our place withi
The authors have correlated many experimental observations and theoretical discussions from the scientific literature on water. Topics covered include the water molecule and forces between water molecules; the thermodynamic properties of steam; the structures of the ices; the thermodynamic, electrical, spectroscopic, and transport properties of the ices and of liquid water; hydrogen bonding in ice and water; and models for liquid water. The main emphasis of the book is on relatingthe properties of ice and water to their structures. Some background material in physical chemistry has been included in order to ensure that the material is accessible to readers in fields such as biology, biochemistry, and geology, as well as to chemists and physicists.
Concepts of Biology is designed for the introductory biology course for nonmajors taught at most two- and four-year colleges. The scope, sequence, and level of the program are designed to match typical course syllabi in the market. Concepts of Biology includes interesting applications, features a rich art program, and conveys the major themes of biology. The images in this textbook are grayscale.
Around 71% of the Earth's surface is covered in water. In this Very Short Introduction John Finney explores the science of water, its structure and remarkable properties, and its vital role for life on Earth.
This book embraces all physiochemical aspects of the structure and molecular dynamics of water, focusing on its role in biological objects, e.g. living cells and tissue, and in the formation of functionally active structures of biological molecules and their ensembles. Water is the single most abundant chemical found in all living things. It offers a detailed look into the latest modern physical methods for studying the molecular structure and dynamics of the water and provides a critical analysis of the existing literature data on the properties of water in biological objects. Water as a chemical reagent and as a medium for the formation of conditions for enzymatic catalysis is a core focus of this book. Although well suited for active researchers, the book as a whole, as well as each chapter on its own, can be used as fundamental reference material for graduate and undergraduate students throughout chemistry, physics, biophysics and biomedicine.
The aim of this book is to explain the unusual properties of both pure liquid water and simple aqueous solutions, in terms of the properties of single molecules and interactions among small numbers of water molecules. It is mostly the result of the author's own research spanning over 40 years in the field of aqueous solutions. An understanding of the properties of liquid water is a prelude to the understanding of the role of water in biological systems and for the evolvement of life. The book is targeted at anyone who is interested in the outstanding properties of water and its role in biological systems. It is addressed to both students and researchers in chemistry, physics and biology.
