From an early age, author Tom Ufert can remember his grandmother proclaiming that adversity builds character. At the time, he didnt completely understand what it meantor know that he would actually live it. In Adversity Builds Character, Ufert shares the events that altered and shaped his life and shows how, with Gods help, he was able to survive, thrive, and inspire others. In this memoir, he narrates his life story and tells about the adversity he has facedhis mothers early divorces; the breakdown of his relationship with his sister; his adoption by family friends; his mothers illness and murder; his contact with a predatory pedophile; his questioning of his own sexuality, bisexuality, and eventual acceptance of being gay; alcoholism and sexual addiction; diagnosis of Multiple Sclerosis and HIV; and paralysis from a car accident. Revealing, honest, painful, and tender, Adversity Builds Character communicates the power of the human spirit to overcome the trials of modern life. It shows how Uferts suffering paved the way for a deep appreciation for life and Gods role in the world.
The capture and use of solar energy has been growing for many years, but only in recent times have advances in design and manufacture allowed us to see the incorporation of solar energy as a significant player in the renewable energy arena. Solar cells are at the heart of any photovoltaic system and in this book the various types are described and their characteristics reviewed. Going beyond materials, design and function, ‘Solar Cells’ also covers their testing, monitoring and calibration thus providing a comprehensive account of current activity in this important field of research and industry. ‘Solar Cells’ has been abstracted from the recent ‘Practical Handbook of Photovoltaics’ by the same editors (ISBN 185617 3909. 2003: Elsevier) Internationally-respected contributors from industry and academia Abstracted from ‘The Practical Handbook of Photovoltaics' by the same Editors A comprehensive source-book on all aspects of solar cells
Solar energy is derived ultimately from the sun. It can be divided into direct and indirect categories. Most energy sources on Earth are forms of indirect solar energy, although we usually don't think of them in that way. Coal, oil and natural gas derive from ancient biological material which took its energy from the sun (via plant photosynthesis) millions of years ago. All the energy in wood and foodstuffs also comes from the sun.Movement of the wind (which causes waves at sea), and the evaporation of water to form rainfall which accumulates in rivers and lakes, are also powered by the sun. Therefore, hydroelectric power and wind and wave power are forms of indirect solar energy. Direct solar energy is what we usually mean when we speak of solar power. Chr(45) is the use of sunlight for heating or generating electricity. Solar energy research and applications have been receiving increasing attention throughout the world as solar energy must play a much greater role in the energy mix in upcoming years. This book examines new research in this frontier field.
