Book Description
The world’s ever-increasing need for fresh water has led to the use of non-conventional sources such as rain and fog water collection. Although rain water collection is relatively simple, the supply is often erratic. Passive fog water collection has been used in several parts of the world but is only relevant to certain geographical locations. Dew occurrence, however, is far more widespread, can form in most climates and geographic settings, show high frequency and prevalence throughout the year. During the past 20 years, dew collection has therefore been investigated as a serious supplemental source of fresh water. Dew Water offers a thorough review of dew, its formation characteristics and potential for dew collection, for audiences that include policy-makers, non-governmental organizations involved in development aid and sustainable development, engineers, urban planners, researchers and students.After providing a background on atmospheric water, humid air, and sky and materials emissivity, the book deals with dew formation and its estimation with a focus on the use of meteorological data. Dew measurement techniques are reviewed and discussed as well as dew collection by passive means. Computational fluid dynamics technique is described for better design of dew collectors. Dew quality (chemistry, biology) is assessed in view of potable water quality. Costs and economic aspects are also considered.

Book Description
Dew Harvest deals with dew harvesting as a feasible solution to the chronic water scarcity in arid areas near the coastline. It substantiates the methodology of dew harvesting based on a case study from the Kothara village in the Kutch region. The book provides insights into the simple and people friendly technology of dew harvesting. It explains the exemplary procedure that Prof. Sharan followed: study of the dew resource of the site, chemical analysis of dew water to verify potability, test of dew harvesting materials, construction of small and pilot-sized dew condensers, and ultimately the construction of a large dew production plant. The author describes the methodology involved in the measurement of dewfall throughout India, especially in the coastal regions. The author recommends that dew harvesting be part of the curriculum at colleges and urges hydrologists and engineers to seriously consider its utility as an innovative technology. This book is the summary then of present technology to harvest dew water through simple and inexpensive means.

Book Description
We meet him late in life: a quiet man, a good father and husband, a fixture in his Brooklyn neighborhood, a landlord and barber with a terrifying scar across his face. As the book unfolds, moving seamlessly between Haiti in the 1960s and New York City today, we enter the lives of those around him, and learn that he has also kept a vital, dangerous secret. Edwidge Danticat’s brilliant exploration of the “dew breaker”--or torturer--s an unforgettable story of love, remorse, and hope; of personal and political rebellions; and of the compromises we make to move beyond the most intimate brushes with history. It firmly establishes her as one of America’s most essential writers. BONUS: This edition includes an excerpt from Edwidge Danticat's Claire of the Sea Light.

Book Description
Even the most competitive companies only close about 15 percent of the deals in their sales pipelines. That means that salespeople spend time with prospects who, 85 percent of the time, aren't going to buy. Wouldn't those salespeople rather spend more time pursuing prospects they knew they could close? Or spend time with their prospects where it matters most at an executive level? Readers who are ready for exceptional results for themselves and their companies need "Selling to Zebras". The Zebra way can help salespeople identify the perfect prospects for their companies--their Zebras--and develop a sales process that will help them close deals 90 percent of the time. The Zebra method of selling will: Increase close rates; Shorten sales cycles; Increase average deal size; Reduce discounting and increase margins; Make better use of scarce resources; Make customers happy, creating a stable of great references. Jeff and Chad Koser don't just offer theories and concepts. They give readers specific tools, models, and spreadsheets they can customise to make the Zebra way the best way for their companies to do business.
