Step-by-step instructions on designing, installing and operating water supply systems based on hydraulic ram pumps. With illustrations and diagrams, and details of a pump designed for local manufacture and notes for those developing their own model. In recent years there has been a revival of interest in the hydraulic ram pump, a renewable energy water-lifting device. Hydraulic Ram Pumps aims to introduce the reader to all aspects of the use of ram pumps. It should be particularly useful to technicians and engineers involved in rural water supply, whether they are assessing the suitability of ram pumps, installing a system or contemplating local manufacture. It gives practical guidelines for the installation and operation of water supply systems based on such pumps, as well as describing the operation of the pump and the factors affecting its performance. The reader is taken through the steps involved in designing and installing a complete system, steps applicable to any model of ram pump available. Details of one pump designed for local manufacture in developing countries are given, along with some notes on ram pump design for those wishing to develop their own models. A large number of illustrations are used alongside a clear and simple text in order to make the information useful to a wide range of non-specialist readers.

"This book explains in detail how a ram pump works, and where it can be set up to pump water above the water source, year-round with virtually no maintainence. Also contained are complete plans for building the prove, nationally sold Atlas Ram Pump. The plans use standard plumbing fittings and requires NO special tools, welding, drilling or tapping to build. " -- Back cover.

This book focuses on water resources and the economic, financial, social and environmental impacts (ICSDWE) of global warming and climate change. It discusses the links between these aspects and presents cutting-edge research, technology, and practice in these fields. The book is a valuable resource for students and researchers at government organizations, academic institutions, and NGOs.

This handbook places emphasis on the importance of correct interpretation of pumping requirements, both by the user and the supplier. Completely reworked to incorporate the very latest in pumping technology, this practical handbook will enable you to understand the principles of pumping, hydraulics and fluids and define the various criteria necessary for pump and ancillary selection. The Pump Users Handbook will prove an invaluable aid in ordering pump equipment and in the recognition of fundamental oprational problems.

Written by an experienced engineer, this book contains practical information on all aspects of pumps including classifications, materials, seals, installation, commissioning and maintenance. In addition you will find essential information on units, manufacturers and suppliers worldwide, providing a unique reference for your desk, R&D lab, maintenance shop or library.* Includes maintenance techniques, helping you get the optimal performance out of your pump and reducing maintenance costs * Will help you to understand seals, couplings and ancillary equipment, ensuring systems are set up properly to save time and money * Provides useful contacts for manufacturers and suppliers who specialise in pumps, pumping and ancillary equipment

"[This book] deserves to be in everyone’s library. . . . It’s loaded with great information, and it can save your life or the life of someone you love."—Dr. Joseph Mercola "This book is life-changing for those trying to understand their own bodies, or those of loved ones, and it’s truly transformative in the hands of medical professionals, especially young doctors."—Foreword Reviews Thomas Cowan was a 20-year-old Duke grad—bright, skeptical, and already disillusioned with industrial capitalism—when he joined the Peace Corps in the mid-1970s for a two-year tour in Swaziland. There, he encountered the work of Rudolf Steiner and Weston A. Price—two men whose ideas would fascinate and challenge him for decades to come. Both drawn to the art of healing and repelled by the way medicine was—and continues to be—practiced in the United States, Cowan returned from Swaziland, went to medical school, and established a practice in New Hampshire and, later, San Francisco. For years, as he raised his three children, suffered the setback of divorce, and struggled with a heart condition, he remained intrigued by the work of Price and Steiner and, in particular, with Steiner’s provocative claim that the heart is not a pump. Determined to practice medicine in a way that promoted healing rather than compounded ailments, Cowan dedicated himself to understanding whether Steiner’s claim could possibly be true. And if Steiner was correct, what, then, is the heart? What is its true role in the human body? In this deeply personal, rigorous, and riveting account, Dr. Cowan offers up a daring claim: Not only was Steiner correct that the heart is not a pump, but our understanding of heart disease—with its origins in the blood vessels—is completely wrong. And this gross misunderstanding, with its attendant medications and risky surgeries, is the reason heart disease remains the most common cause of death worldwide. In Human Heart, Cosmic Heart, Dr. Thomas Cowan presents a new way of understanding the body’s most central organ. He offers a new look at what it means to be human and how we can best care for ourselves—and one another.

This two-volume set constitutes the refereed post-conference proceedings of the 8th International Conference on Advancement of Science and Technology, ICAST 2020, which took place in Bahir Dar, Ethiopia, in October 2020. The 74 revised full papers were carefully reviewed and selected from more than 200 submissions of which 157 were sent out for peer review. The papers present economic and technologic developments in modern societies in 6 tracks: Chemical, food and bio-process engineering; Electrical and computer engineering; IT, computer science and software engineering; Civil, water resources, and environmental engineering; Mechanical and industrial engineering; Material science and engineering.
