An enthralling collection of 45 dramatic stories of yachts lost at sea, Total Loss has been a consistent bestseller since first publication. This fascinating new edition carries exciting first-hand accounts, including the tragic sinking of the yacht Ouzo, run down or swamped by a P&O ferry in the English Channel, the loss of Hooligan V, the sinking of two boats in the Atlantic after rudder failure, and the rescue of Pete Goss and his crew from the giant catamaran Team Philips. Here are tales of collisions with UFOs (unidentified floating objects), fire, explosion, exhaustion and crew failure, navigational blunders, capsize, gear failure, dismastings and severe storms. The moving, emotionally charged descriptions of shipwrecked sailors abandoning their yachts at sea will have you on the edge of your seat. But these accounts are more than just gripping tales of disaster - they carry valuable lessons which the survivors have been able to pass on to all who go to sea for pleasure. Every year, hundreds of yachts are lost at sea. For those who wish to avoid a similar fate, or learn how best to cope with emergencies, this book is a compelling, thought-provoking bunkside read.

Who knew there were so many bluegrasses in Mexico?ÿ This monographic study of the Mexican species of the large (500+ species), taxonomically complex, world-wide genus Poa, by Smithsonian researchers Robert J. Soreng and Paulÿ M. Peterson, revealed there were 23, including 2 new to science, and 2 previously unknown there.ÿ Two other narrow endemics were described only in the last 10 years. The Mexican species occur mainly in the mountains, and especially in the alpine.ÿ Most of the species occurrences in Mexico presumably reflect establishment during cooler climates of past glacial cycles. Today, several are living on the edge of extinction. Eleven natives are globally rare, or rare in Mexico. Breeding system diversity is high: asexual seed production is obligate in several and facultative in some others, one is dioecious, and some are gynomonoecious, several are perfect-flowered.ÿ At least 3 arrived by long-distance-dispersal from South America?s Andes; 2 aided by asexual reproduction, 1 by the capacity to self-fertilize.
Underwater Acoustic Modeling and Simulation, Fourth Edition continues to provide the most authoritative overview of currently available propagation, noise, reverberation, and sonar-performance models. This fourth edition of a bestseller discusses the fundamental processes involved in simulating the performance of underwater acoustic systems and emphasizes the importance of applying the proper modeling resources to simulate the behavior of sound in virtual ocean environments. New to the Fourth Edition Extensive new material that addresses recent advances in inverse techniques and marine-mammal protection Problem sets in each chapter Updated and expanded inventories of available models Designed for readers with an understanding of underwater acoustics but who are unfamiliar with the various aspects of modeling, the book includes sufficient mathematical derivations to demonstrate model formulations and provides guidelines for selecting and using the models. Examples of each type of model illustrate model formulations, model assumptions, and algorithm efficiency. Simulation case studies are also included to demonstrate practical applications. Providing a thorough source of information on modeling resources, this book examines the translation of our physical understanding of sound in the sea into mathematical models that simulate acoustic propagation, noise, and reverberation in the ocean. The text shows how these models are used to predict and diagnose the performance of complex sonar systems operating in the undersea environment.
Philadelphia is famous for its colonial and revolutionary buildings and artifacts, which draw tourists from far and wide to gain a better understanding of the nation’s founding. Philadelphians, too, value these same buildings and artifacts for the stories they tell about their city. But Philadelphia existed long before the Liberty Bell was first rung, and its history extends well beyond the American Revolution.In Philadelphia: A Narrative History, Paul Kahan presents a comprehensive portrait of the city, from the region’s original Lenape inhabitants to the myriad of residents in the twenty-first century. As any history of Philadelphia should, this book chronicles the people and places that make the city unique: from Independence Hall to Eastern State Penitentiary, Benjamin Franklin and Betsy Ross to Cecil B. Moore and Cherelle Parker. Kahan also shows us how Philadelphia has always been defined by ethnic, religious, and racial diversity—from the seventeenth century, when Dutch, Swedes, and Lenapes lived side by side along the Delaware; to the nineteenth century, when the city was home to a vibrant community of free Black and formerly enslaved people; to the twentieth century, when it attracted immigrants from around the world. This diversity, however, often resulted in conflict, especially over access to public spaces. Those two themes— diversity and conflict— have shaped Philadelphia’s development and remain visible in the city’s culture, society, and even its geography. Understanding Philadelphia’s past, Kahan says, is key to envisioning future possibilities for the City of Brotherly Love.

Universally acclaimed for their compelling narrative, their fresh insights, and their objective renderings of Winston Churchill's life, The Last Lion trilogy presents a revelatory and unparalleled portrait of this brilliant, flawed, and dynamic adventurer, aristocrat, soldier, and statesman. Born at the end of the 19th century when Imperial Britain still stood at the splendid pinnacle of her power, Churchill would witness the shift a few years later as the Empire hovered on the brink of a catastrophic new era. One of the greatest wartime leaders of our time, he would go on to stand alone, politically isolated in Parliament, as he took the lead in warning of the growing Nazi threat, and would lead Britain to victory against Nazi Germany and the Axis powers in World War II. Now, celebrated historian William Manchester's landmark biographies are collected together for the first time, along with the eagerly anticipated final installment Churchill's last years in power. More than thirty years in the making, The Last Lion is the definitive work on this remarkable man whose courageous vision guided the destiny of a nation during darkly troubled times-and who looms as one of the greatest figures of our century.
This book synthesises the growing body of evidence which suggests that modern-day birds have evolved from theropod dinosaurs of prehistoric times. The author argues that the ancestor-descendant relationship can also be reversed.

Using original Victorian prints, by collectable artist George Sowerby, marine biologist and author Paul Chambers has produced the first comprehensive guide to shells for over a century. The original prints are intricately detailed (much better than photographs which lack the exact detail of these drawings) and are a selling point in themselves but will be complemented by informative but accessible text, including families and to show what's edible, dangerous or belongs to mollusk families and in what part of the country they can be discovered. A delightful study by the leading expert and a must for anyone interested in learning more about shells - or who just enjoys beach combing with the family.
