Water-Soluble Synthetic Polymers: Volume II: Properties and Behavior
by Philip MolyneuxAlthough several monographs and reviews have appeared on individual polymers of this type, and their applications and other technical aspects have also been discussed, this is apparently the first book to deal with the physical chemistry of water-soluble synthetic polymers as a group. This collective survey enables their properties and behaviour to be compared, and to be correlated with their molecular structures for predictive purposes. However, this has made it necessary to critically re-appraise much of the earlier fundamental work, so that current discussion of more recent work can be put on ta proper basis. Thus, of the 1800 or so references cited, the middle two-thirds related to the twenty-year period centred on about 1968. Nevertheless, sufficient key recent references have also been included so that the existing ‘state of the art is delineated.

Water Soluble Vitamins
by Olaf StangerThe discovery of vitamins in the early 1900s, their later chemical characterization and the clarification of pivotal metabolic functions are sequential aspects of a brilliant chapter in the history of modern nutritional sciences and medicine. The name, derived from "vital-amines", indicates their elementary metabolic key functions in human metabolism. Vitamins are truly families of compounds, which include precursors and various free and bound forms, all with individual roles in metabolism and function. A more recent approach therefore searches for the components, the understanding of their roles in physiology and pathology as well as looking for novel pharmacological applications. When used properly, vitamins are, indeed, "magical" substances. Due to their efficacy, they should therefore be regarded as drugs with effects and side effects to be weighted against each other. Today, it is not the previously fatal deficiency-associated diseases that are in the focus of interest, but rather the relation of suboptimal vitamin bioavailability to chronic disease. This is complicated by genetic susceptibility, lifestyle, and the presence or absence of health-compromising habits, such as smoking. In turn, the development and application of new and more sensitive and specific assays further enable us to look more closely into the many functions of vitamins. Water soluble vitamins are complex molecular structures and even today, many areas in vitamin biochemistry are not yet fully understood. Novel effects and functions of vitamins remain and continue to be discovered. This book presents most recent research results and fascinating new knowledge on the role and effects of the water soluble vitamins in man. Some of the most distinguished chemists, biochemists, biologists and clinicians have contributed valuable chapters sharing unexpected novel insights into the biochemistry, (epi)genetics, metabolism, and function of water soluble vitamins, with their potential for clinical applications. Thus, physicians, clinicians, scientists, researchers, epidemiologists. nutritional specialists and health professionals alike will find stimulating and fascinating new insight in the many roles that water soluble vitamins play in human health and disease.
Water Stress and Crop Plants: A Sustainable Approach, 2 Volume Set
by Parvaiz AhmadPlants are subjected to a variety of abiotic stresses such as drought, temperature, salinity, air pollution, heavy metals, UV radiations, etc. To survive under these harsh conditions plants are equipped with different resistance mechanisms which vary from species to species. Due to the environmental fluctuations agricultural and horticultural crops are often exposed to different environmental stresses leading to decreased yield and problems in the growth and development of the crops. Drought stress has been found to decrease the yield to an alarming rate of some important crops throughout the globe. During last few decades, lots of physiological and molecular works have been conducted under water stress in crop plants.Water Stress and Crop Plants: A Sustainable Approach presents an up-to-date in-depth coverage of drought and flooding stress in plants, including the types, causes and consequences on plant growth and development. It discusses the physiobiochemical, molecular and omic approaches, and responses of crop plants towards water stress. Topics include nutritional stress, oxidative stress, hormonal regulation, transgenic approaches, mitigation of water stress, approaches to sustainability, and modern tools and techniques to alleviate the water stress on crop yields. This practical book offers pragmatic guidance for scientists and researchers in plant biology, and agribusinesses and biotechnology companies dealing with agronomy and environment, to mitigate the negative effects of stress and improve yield under stress. The broad coverage also makes this a valuable guide enabling students to understand the physiological, biochemical, and molecular mechanisms of environmental stress in plants.
Water Supply and Demand Management in the Galápagos: A Case Study of Santa Cruz Island
by Maria Fernanda Reyes PerezWater resources in tourist islands have been severely threatened, especially in the Galápagos Islands, where the increased local population has generated attractive income from the tourist services. In addition, the data regarding water supply and demand are scarce. This study investigates water supply and demand in Santa Cruz, the most populated island of Galápagos. The research encompasses a thorough assessment of the water supply crisis, as well as the quantification of water demand from different categories (domestic, tourist, restaurants and laundries) through surveys, in the absence of water metering. Also, specific water demand was assessed by installing 18 water meters. The results yield a wide range of water consumption, questioning the current assumption of water scarcity. Furthermore, a prognosis of water supply and demand was carried out, and also several intervention strategies were proposed such as rainwater harvesting, greywater recycling, leakage reduction, water meter installation, water demand reduction, as well as seawater desalination to cope with the future population growth. Due to the fragility of the ecosystem, these strategies were assessed through a Multi-Criteria Decision Analysis, considering environmental, technical, economic and social aspects, as well as relevant stakeholders’ perspectives. finally, the water supply network of Puerto Ayora was evaluated in order to understand the need of the current intermittent supply regime. A methodology was developed to estimate the overflow of the domestic roof tanks (a common incidence amongst local population). The results question the practicality of individual household storage. The final results show that the current situation in terms of the lack of water quantity may not be real, as it has been thought for the last decades. The water issues refer more importantly to the water quality, as well as to the lack of proper water management practices.

Water Treatment in Urban Environments: Examples from South/Southeast Asia (Applied Environmental Science and Engineering for a Sustainable Future)
by Veeriah Jegatheesan Perlie Velasco Nevelina PachovaThe value of implementing nature-based solutions (NbS) for water treatment in urban environments is increasingly recognized due to the multiple ecosystem services and societal benefits they provide. The successful implementation of NbS for urban water treatment, however, depends on a range of diverse technical and societal factors that need to be taken into account. Those vary by the type of NbS implemented, the societal challenges the NbS are designed to address and the local ecological, socio-economic and political context, in which the solutions are implemented. This book provides a collection of guidelines for the implementation of three types of NbS for water treatment in urban environments across cities in South/Southeast Asia, namely constructed wetlands, green roofs and floating treatment wetlands. The guides were developed based on existing experiences with the establishment, operation, and maintenance of those three types of NbS in three different countriesin South/Southeast Asia and the lessons learnt from their implementation. They provide detailed outlines of suggested steps for ensuring successful implementation in the respective local contexts. Those include overall planning schemes, surveys for socio-economic evaluations, suggested methods for construction and associated costs, required maintenance as well as a range of operational monitoring parameters. It also includes examples of approaches for the scaling of the three types of NbS discussed in the book in their respective local contexts. This book is expected to benefit local government units and contractors, and other stakeholders involved in NbS implementation and up-scaling, as well as researchers and postgraduate students who plan to conduct pilot-scale studies on NbS.

Water Waves and Ship Hydrodynamics: An Introduction
by A. J. HermansIn this book an introduction is given to aspects of water waves that play a role in ship hydrodynamics and offshore engineering. At first the equations and linearized boundary conditions are derived describing the non-viscous free surface water waves, with special attention to the combination of steady and non-steady flow fields. Then some simple kinds of free wave solutions are derived, such as plane waves and cylindrical waves. For several situations, steady and unsteady, the source singularity function is derived. These functions play a role in numerical codes used to describe the motion of ships and offshore structures. These codes are mostly based on a boundary integral formulation; therefore we give an introduction to these methods. It is shown how first order ship motions can be determined. In offshore engineering the second order wave drift motions play an important role. An introduction to this phenomenon is given and the effects which have to be taken into account are explained by means of a simple example where we can determine nearly all the aspects analytically. An interesting example that is worked out is the motion of very large floating flexible platforms with finite draft. Finally an introduction to the theory of shallow water non-linear dispersive waves is presented, and shallow water ship hydrodynamics, that plays a role in coastal areas and channels is treated. Here attention is paid to the interaction between passing ships in restricted water. In the appendix a short introduction to some of the mathematical tools is given.
The Water Will Come: Rising Seas, Sinking Cities, And The Remaking Of The Civilized World
by Jeff GoodellAn eye-opening and essential tour of the vanishing world What if Atlantis wasn't a myth, but an early precursor to a new age of great flooding? <P><P>Across the globe, scientists and civilians alike are noticing rapidly rising sea levels, and higher and higher tides pushing more water directly into the places we live, from our most vibrant, historic cities to our last remaining traditional coastal villages. With each crack in the great ice sheets of the Arctic and Antarctica, and each tick upwards of Earth's thermometer, we are moving closer to the brink of broad disaster. <P><P>By century's end, hundreds of millions of people will be retreating from the world's shores as our coasts become inundated and our landscapes transformed. From island nations to the world's major cities, coastal regions will disappear. Engineering projects to hold back the water are bold and may buy some time. <P><P>Yet despite international efforts and tireless research, there is no permanent solution-no barriers to erect or walls to build-that will protect us in the end from the drowning of the world as we know it. <P><P>The Water Will Come is the definitive account of the coming water, why and how this will happen, and what it will all mean. As he travels across twelve countries and reports from the front lines, acclaimed journalist Jeff Goodell employs fact, science, and first-person, on-the-ground journalism to show vivid scenes from what already is becoming a water world.

The Water–Food–Energy Nexus: Power, Politics, and Justice (Pathways to Sustainability)
by Jeremy Allouche Carl Middleton Dipak GyawaliThe world of development thinkers and practitioners is abuzz with a new lexicon: the idea of "the nexus" between water, food, and energy which is intuitively compelling. It promises better integration of multiple sectoral elements, a better transition to greener economies, and sustainable development. However, there appears to be little agreement on its precise meaning, whether it only complements existing environmental governance approaches or how it can be enhanced in national contexts. One current approach to the nexus treats it as a risk and security matter while another treats it within economic rationality addressing externalities across sector. A third perspective acknowledges it as a fundamentally political process requiring negotiation amongst different actors with distinct perceptions, interests, and practices. This perspective highlights the fact that technical solutions for improving coherence within the nexus may have unintended and negative impacts in other policy areas, such as poverty alleviation and education. The Water–Food–Energy Nexus: Power, Politics and Justice lays out the managerial-technical definitions of the nexus and challenges these conceptions by bringing to the forefront the politics of the nexus, around two key dimensions – a dynamic understanding of water–food–energy systems, and a normative positioning around nexus debates, in particular around social justice. The authors argue that a shift in nexus governance is required towards approaches where limits to control are acknowledged, and more reflexive/plural strategies adopted. This book will be of interest to academic researchers, policy makers, and practitioners in the fields of international development studies, environmental politics, and science and technology studies, as well as international relations.

Watermark
by Christy-VitaleTHE ECHOES OF OUR PAST Twelve thousand years ago, the human race barely escaped annihilation when a piece of exploded star passed through our solar system, unleashing an apocalypse. Great fires raged, mountains rose and fell, a maelstrom of cosmic debris bombarded Earth, continents broke apart, and oceans swept across the land. Millions of people, animals, and plants perished almost overnight. Entire societies, cultures, and belief systems were lost forever. The resulting aftershock shaped humanity for thousands of years, and continues to haunt us to this day. This is not fiction. This is history. THE TRUTHS OF THE PRESENT Using authoritative source material and an understanding of mankind's aptitude for the transmission of factual knowledge through myth and legend, Joseph Christy-Vitale dramatically unveils a past unlike any proposed by either religion or science, viewing the global catastrophe as living history, since the traumatic effects of that terrible event affect us as a species even today. THE PATHS OF THE FUTURE Providing an insight into where our troubled view of the world originated, Watermark tells the true story of how humanity's brush with extinction still pervades our lives -- and offers the first step to recovering what we lost so long ago: a healthy, balanced view of the world.
