"As the race for resources in distant parts of the planet gathers momentum, most discussion has centered on the potential for conflict, environmental destruction, and upheaval from climate change. This important book shifts the conversation about the Arctic and Antarctic from conflict to cooperation. A multidisciplinary roster of experts provides fresh views of the polar regions, focusing on diplomacy and the potential for cooperative international decision-making. Collectively the contributors illustrate the breadth of issues that complicate governance in the Arctic and Antarctic, as well as parallels and differences between the politics of the two poles"--

This report describes flow-control methods for reducing ice problems in rivers. Objectives include reducing ice interference with winter hydroelectric production and navigation, ice jam flood mitigation, as well as ensuring minimum winter flows for fish and water supply. The winter season is divided into three periods. During early winter, the main objective of flow control is to promote the rapid formation of a smooth, stable ice cover. For the midwinter period, the aim of the river regulation is to maintain an intact ice cover and avoid premature ice breakup. During the final winter period, the goal is to minimize adverse effects of ice breakup. Examples illustrate the methods and objectives, emphasizing innovative approaches. Available flow regulation planning tools are described and valuable research directions identified.

At the age of twenty-two, Kayy Gordon headed for the Arctic Circle to be a missionary among the Inuit. There she adapted to the land of the midnight sun, sharing with the Inuit their camp life and winter storms, traveling with the reindeer herders, learning to enjoy whale meat and frozen fish. But most of all she shared with them the story of Jesus. She prayed with them, cried with them and ministered wherever she could. Fifty years later Kayy still travels in the North. And with her, the power of the Holy Spirit has taken the ice and set it on fire. . .

Like many a Canadian kid, Stephen Smith was up on skates first thing as a boy, out in the weather chasing a puck and the promise of an NHL career. Back indoors after that didn’t quite work out, he turned to the bookshelf. That’s where, without entirely meaning to, he ended up reading all the hockey books. There was Crunch and Boom Boom, Slashing! and High Stick; there was Max Bentley: Hockey’s Dipsy-Doodle Dandy, Blue Line Murder, and Nagano, a Czech hockey opera. There was Blood on the Ice, Cracked Ice, Fire On Ice, Power On Ice, Cowboy On Ice, and Steel On Ice. In Puckstruck, Smith chronicles his wide-eyed and sometimes wincing wander through hockey’s literature, language, and culture, weighing its excitement and unbridled joy against its costs and vexing brutality. In exploring his own lifelong love of the game, hoping to surprise some sense out of it, he sifts hockey’s narratives in search of hockey’s heart, what it means and why it should distress us even as we celebrate its glories. On a journey to discover what the game might have to say about who we are as Canadians, he seeks to answer some of its essential riddles.

The Ice Age Challenge refers to the challenge that we face globally to create a new foundation for living when the coming Ice Age climate shuts down most of the world's agriculture, possibly 100 to 150 years from now. The novel is the first part of the second episode of the series, The Lodging for the Rose, an eight-part science-fantasy centered on universal love, by Rolf A. F. Witzsche. - We truly are in a race against time, the greatest race since the dawn of man, 'racing' to create the technologies, economies, finances, politics, and social cultures that enable us to shift agriculture into efficient indoor facilities in order to protect our food production in the coming Ice Age environment. The Earth has been in an Ice Age for 1.8 million years, interspersed by the occasional warm period, like the present one that is ending in spite of global warming. The necessary infrastructures for survival are technologically feasible, but will we empower ourselves to create them? That appears to be less certain. It seems that we have been put in race without the skills for it. But then, don't we have the potential to be fast learners? In the course of exploring the question the novel touches on the collapse of the Soviet Union, the Aryan invasion in historic India, the face of Islam, the fascist holocaust, depopulation, global warming, nuclear fusion power, indoors agriculture, and principles of marriage, sex, culture, and science.

Initially, the only electric loads encountered in an automobile were for lighting and the starter motor. Today, demands on performance, safety, emissions, comfort, convenience, entertainment, and communications have seen the working-in of seemingly innumerable advanced electronic devices. Consequently, vehicle electric systems require larger capacities and more complex configurations to deal with these demands. Covering applications in conventional, hybrid-electric, and electric vehicles, the Handbook of Automotive Power Electronics and Motor Drives provides a comprehensive reference for automotive electrical systems. This authoritative handbook features contributions from an outstanding international panel of experts from industry and academia, highlighting existing and emerging technologies. Divided into five parts, the Handbook of Automotive Power Electronics and Motor Drives offers an overview of automotive power systems, discusses semiconductor devices, sensors, and other components, explains different power electronic converters, examines electric machines and associated drives, and details various advanced electrical loads as well as battery technology for automobile applications. As we seek to answer the call for safer, more efficient, and lower-emission vehicles from regulators and consumer insistence on better performance, comfort, and entertainment, the technologies outlined in this book are vital for engineering advanced vehicles that will satisfy these criteria.

The Power of Purpose begins with a simple but remarkable statement: “The more you focus on helping others, the more you will succeed in reaching your own goals.” Peter S. Temes builds on this fundamental insight to share a simple plan for living with the truest and most enduring kind of happiness. At the heart of The Power of Purpose are the “three levels of thinking.” At the first level, we ask, Who am I? and What do I want? At the second level, we ask, Who do other people think I am? How do I look to them? But the real magic happens when we hit the third level, forgetting about ourselves and asking the questions that lend a powerful sense of purpose to our lives: How do others look to themselves? How can I help others become the people they want to be? To help us along the way, Temes, who teaches humanities at Columbia University, draws on the wisdom of great thinkers including Aristotle, Søren Kierkegaard, and Abraham Lincoln; the life lessons of great achievers ranging from Mother Teresa to Michael Jordan; and home truths he’s gathered from his parents, his grandparents, and his three children. From all these sources and from his own life of great personal accomplishment, Temes identifies the essential knowledge that brings people happiness and success. He cites Aristotle’s notion that happiness is not a psychological state but a moral one, resulting from doing good in the world. Temes also believes in the pivotal importance of trust and team-building in every area of life, from the family to the workplace to the street corner. The Power of Purpose is a map for finding the confidence and power, the opportunities and occasions, and—most important—the techniques and strategies for centering your relationships and work on helping others. It is a book with a point of view: the clearest path to your own success and happiness lies in helping others get to where they want to go.
