Book Description
The book presents the fantastic world of water in all its different forms, from liquid to ice and snow. This book is amply illustrated with a large number of beautiful pictures with. Water plays a unique role in chemistry. The special properties of water are due to hydrogen bonding between the H2O molecules. The hydrogen bond is of fundamental importance in biological systems since all living matter has evolved from and exists in an aqueous environment, and hydrogen bonds are involved in most biological processes. There is a hundred times more water molecules in our bodies than the sum of all the other molecules put together.The unique properties of water are of great importance in our daily life. The origin of these special properties is often not recognized. Even among chemists and physicists, the fundamental facts are not always known. In spite of very active research, there are still many questions to be answered about the structure of liquid water, for instance.The book differs from most books on water as it covers basic facts about structure and properties as well as the influence of these properties in our daily life. Why does ice float on water? Why is the maximum density of water at 4°C? The beauty of snow crystals is amply illustrated, and many of the pictures are unique.

Book Description
'Cities are not just brick and mortar; they represent the dreams, aspirations, and hopes of societies.'UN Habitat (2008)Urban lakes are part of many of the cities we live in. They are often intricately bound with the city's social fabric, valued for direct utility purposes such as drinking water provision, or for their aesthetic, historical, cultural, and religious significance. However, oftentimes in spite of their unique spatial, socio-cultural, and economic value and 'relationship' with the city, urban lakes end up as receptacles for waste, or are infilled for development.This book traces the socio-cultural and technological dimensions at play for the protection and remediation of a tropical urban lake, and how these dimensions guide the design of need-based solutions. It explores design requirements based on the need for sensitivity to religious and cultural norms, social values and aesthetic requirements. First-hand experiences of the writers in planning and executing an urban lake remediation project in a fast-growing city and a UNESCO heritage site, are drawn as practical examples. The lessons learnt can find application in other lakes of cultural significance in tropical regions.

Book Description
Facing droughts, floods, and water security challenges, society is increasingly forced to develop new policies and practices to cope with the impacts of climate change. From taken-for-granted values and perceptions to embodied, existential modes of engaging our world, human perspectives impact decision-making and behaviour. The Wonder of Water explores how human experience – including our cultural paradigms, value systems, and personal biases – impacts decisions around water. In many ways, the volume expands on the growing field of water ethics to include questions around environmental aesthetics, psychology, and ontology. And yet this book is not simply for philosophers. On the contrary, a specific aim is to explore how more informed philosophical dialogue will lead to more insightful public policies and practices. Case studies describe specific architectural and planning decisions, fisheries policies, urban ecological restorations, and more. The overarching phenomenological perspective, however, means that these discussions emerge within a sensibility that recognizes the foundational significance of human embodiment, culture, language, worldviews, and, ultimately, moral attunement to place.

Book Description
As one of the typical intermolecular interactions, hydrogen-bonding plays a significant role in molecular structure and function. When the hydrogen bond research system is connected with the photon, the hydrogen-bonding effect turns to an excited-state one influencing photochemistry, photobiology, and photophysics. Thus, the hydrogen bond in an excited state is a key topic for understanding the excited-state properties, especially for optoelectronic or luminescent materials.The approaches presented in this book include quantum chemical calculation, molecular dynamics simulation and ultrafast spectroscopy, which are strong tools to investigate the hydrogen bond. Unlike other existing titles, this book combines theoretical calculations and experiments to explore the nature of excited-state hydrogen bonds. By using these methods, more details and faster processes involved in excited-state dynamics of hydrogen bond are explored.This highly interdisciplinary book provides an overview of leading hydrogen bond research. It is essential reading for faculties and students in researching photochemistry, photobiology and photophysics, as well as novel optoelectronic materials, fluorescence probes and photocatalysts. It will also guide research beginners to getting a quick start within this field.

Book Description
Now in its second edition, Water Resources: An Integrated Approach provides students with a comprehensive overview of natural processes associated with water and the modifications of these processes by humans through climate change and land management, water-related health issues, engineering approaches to water and socio-economic processes of huge importance to water resources. The book contains chapters written by 24 specialist contributors, providing expert depth of coverage to topics. The text introduces the basic properties of water and its importance to society and the nature of the different regional imbalances between water resource availability and demand. It guides the reader through the changing water cycle impacted by climate and land management, water flows in river basins, surface water quality, groundwater and aquatic ecosystems, and covers the role of water in human health and associated hazards before turning to engineering solutions to water and wastewater treatment and reuse. The book deals with physical and social management strategies required for water resource planning, the economics of water and treatment of issues associated with conflict over water. The concept of virtual water is covered before the text concludes with a chapter considering the challenges of predicting future water issues in a rapidly changing world and where environmental systems can behave in a non-linear way. The need to work across disciplines to address challenges that are connected at both local and global scales is highlighted. Water Resources also includes global examples from both the developing and developed world. There are 58 case study boxes. Each chapter is supplemented with these case studies and with reflective questions, project ideas and further reading, as well as links to a glossary of terms. The book is richly illustrated throughout with over 160 full-colour diagrams and photographs. The text provides a novel interdisciplinary approach to water in a changing world, from an environmental change perspective and interrelated social, political and economic dimensions. It will be an indispensable guide to undergraduates studying water resources and management, geography of water, and water in the environment.

Book Description
There is nothing in the universe like water. It is unique and beautiful and without it there could be no life on earth. Little wonder, then, that people have always expressed such awe, delight, and reverence for it. The Bird in the Waterfall is a celebration of the wonders of water and the creatures that live in it. While exploring waterfalls and artesian springs, ocean waves and tidal bores, whirligig beetles and torrent ducks, author Jerry Dennis and artist Glenn Wolff address age-old aquatic mysteries: Why do rivers meander? What are the sources of hot springs and geysers? What causes tsunamis and rogue waves? Why is water blue—and sometimes green, black, yellow, or red? Why do we gather to watch falling water and crashing surf? Why do we toss coins into fountains? At the heart of The Bird in the Waterfall is a profound appreciation for the magic, music, and poetry of water—and a passionate appeal for the protection of this most precious of the earth’s resources. PRAISE: “A passionate appreciation for the magic, music, and poetry of water, and an appeal for the protection of this most precious of the earth’s resources.” —Natural Resources and Wildlife Magazine “Jerry Dennis is one of today’s most readable and informative nature essayists, and his latest book, The Bird in the Waterfall, is a marvelous look at the natural history of oceans, rivers, and lakes. It ought to be required reading for anyone who loves the outdoors, angling, surfing, beachcombing, or birding.” —Buffalo News “The Bird in the Waterfall is truly science for everyone. When you have finished reading it, you will not only know more, but you may become as charmed with water as Dennis is.” —Earth Magazine “I can’t think of anyone I know—angler, conservationist, scientific reader, curious kid—who wouldn’t enjoy, and learn from, this unusual book. And from endpaper to endpaper, it’s a visual delight, too.” —Fly Rod and Reel Magazine “Nature writer Dennis conveys his deep feelings for all aspects of the aquatic realm…and parlays his fascination with the dynamics of bodies of water into a richly informative description of how lakes and rivers support myriad lifeforms.” —Booklist

Book Description
Doing Honest Work in College stands on three principles: do the work you say you do, give others credit, and present your research fairly. These are straightforward concepts, but the abundance of questionable online sources and temptation of a quick copy-paste can cause confusion as to what’s considered citing and what’s considered cheating. This guide starts out by clearly defining plagiarism and other forms of academic dishonesty and then gives students the tools they need to avoid those pitfalls. This edition addresses the acceptable use of mobile devices on tests, the proper approach to sources such as podcasts or social media posts, and the limitations of citation management software.
