Book Description
There has been an exponential increase in desalination capacity both globally and nationally since 1960, fueled in part by growing concern for local water scarcity and made possible to a great extent by a major federal investment for desalination research and development. Traditional sources of supply are increasingly expensive, unavailable, or controversial, but desalination technology offers the potential to substantially reduce water scarcity by converting the almost inexhaustible supply of seawater and the apparently vast quantities of brackish groundwater into new sources of freshwater. Desalination assesses the state of the art in relevant desalination technologies, and factors such as cost and implementation challenges. It also describes reasonable long-term goals for advancing desalination technology, posits recommendations for action and research, estimates the funding necessary to support the proposed research agenda, and identifies appropriate roles for governmental and nongovernmental entities.

Book Description
Nature is fragile, environmentalists often tell us. But the lesson of this book is that it is not so. The truth is far more worrying. Nature is strong and packs a serious counterpunch . . . Global warming will very probably unleash unstoppable planetary forces. And they will not be gradual. The history of our planet's climate shows that it does not do gradual change. Under pressure, whether from sunspots or orbital wobbles or the depredations of humans, it lurches-virtually overnight. —from the Introduction Fred Pearce has been writing about climate change for eighteen years, and the more he learns, the worse things look. Where once scientists were concerned about gradual climate change, now more and more of them fear we will soon be dealing with abrupt change resulting from triggering hidden tipping points. Even President Bush's top climate modeler, Jim Hansen, warned in 2005 that "we are on the precipice of climate system tipping points beyond which there is no redemption." As Pearce began working on this book, normally cautious scientists beat a path to his door to tell him about their fears and their latest findings. With Speed and Violence tells the stories of these scientists and their work-from the implications of melting permafrost in Siberia and the huge river systems of meltwater beneath the icecaps of Greenland and Antarctica to the effects of the "ocean conveyor" and a rare molecule that runs virtually the entire cleanup system for the planet. Above all, the scientists told him what they're now learning about the speed and violence of past natural climate change-and what it portends for our future. With Speed and Violence is the most up-to-date and readable book yet about the growing evidence for global warming and the large climatic effects it may unleash.

Book Description
The authors preceive a trend in the study and practice of groundwater hydrology. They see a science that is emerging from its geological roots and its early hydraulic applications into a full-fledged environmental science. They see a science that is becoming more interdisciplinary in nature and of greater importance in the affairs of man. This book is their response, and they have provided a text that is suited to the study of groundwater during this period of emergence.

Book Description
Heritage is synonymous with Nassau Country Club, home of the "two dollar Nassau wager"; also of the original Calamity Jane, renowned putter of Bobby Jones, & the Nassau bowl, oldest tennis award in the U.S. This Nassau Journey began 100 years ago in the heart of the old Gold Coast of Glen Cove, Long Island. The founders were rich in the history of this country at the turn into the 1900's. Among its first golf professionals were Alex Smith & Jimmie Maiden, from Carnoustie, Scotland. Nassau CC was The Place To Be for Jones, Travers, & Hagen, Vardon & Ray--for Nassau Bowl aspirants tennis greats Clothier, Tilden, Riggs, Trabert & Newcombe--J. P. Morgan & Percy Chubb--past Presidents of the U.S., luminaries, & royalty from abroad. Nassau is that rich in past tournaments in golf, lawn tennis, & squash that we earnestly researched & detailed many matches stroke by stroke; although unique for a club history, we invite the true follower to relive the excitement of days past to the present. Along the way, we introduce our members, their fun ways, the challenges exacerbated by two world wars, & the paths followed to solve problems & insure a future bicentennial.

Book Description
This book had its genesis in a symposium on gas hydrates presented at the 2003 Spring National Meeting of the American Institute of Chemical Engineers. The symposium consisted of twenty papers presented in four sessions over two days. Additional guest authors were invited to provide continuity and cover topics not addressed during the symposium. Gas hydrates are a unique class of chemical compounds where molecules of one compound (the guest material) are enclosed, without bonding chemically, within an open solid lattice composed of another compound (the host material). These types of configurations are known as clathrates. The guest molecules, u- ally gases, are of an appropriate size such that they fit within the cage formed by the host material. Commonexamples of gas hydrates are carbon dioxide/water and methane/water clathrates. At standard pressure and temperature, methane hydrate contains by volume 180 times as much methane as hydrate. The United States Geological Survey (USGS) has estimated that there is more organic carbon c- tained as methane hydrate than all other forms of fossil fuels combined. In fact, methane hydrates could provide a clean source of energy for several centuries. Clathrate compounds were first discovered in the early 1800s when Humphrey Davy and Michael Faraday were experimenting with chlorine-water mixtures.

Book Description
This practical textbook covers key areas like the foundations of public health, concepts and tools of policy, and models of public health programs run by pharmacists. Unlike other books, it includes real-life cases that highlight pharmacists who are starting or getting involved in public health efforts.
