Book Description
By the time the “Scramble for Africa” among European colonial powers began in the late nineteenth century, Africa had already been globally connected for centuries. Its gold had fueled the economies of Europe and the Islamic world for nearly a millennium, and the sophisticated kingdoms spanning its west coast had traded with Europeans since the fifteenth century. Until at least 1650, this was a trade of equals, using a variety of currencies—most importantly, cowrie shells imported from the Maldives and nzimbu shells imported from Brazil. But, as the slave trade grew, African kingdoms began to lose prominence in the growing global economy. We have been living with the effects of this shift ever since. With A Fistful of Shells, Toby Green transforms our view of West and West-Central Africa by reconstructing the world of these kingdoms, which revolved around trade, diplomacy, complex religious beliefs, and the production of art. Green shows how the slave trade led to economic disparities that caused African kingdoms to lose relative political and economic power. The concentration of money in the hands of Atlantic elites in and outside these kingdoms brought about a revolutionary nineteenth century in Africa, parallel to the upheavals then taking place in Europe and America. Yet political fragmentation following the fall of African aristocracies produced radically different results as European colonization took hold. Drawing not just on written histories, but on archival research in nine countries, art, oral history, archaeology, and letters, Green lays bare the transformations that have shaped world politics and the global economy since the fifteenth century and paints a new and masterful portrait of West Africa, past and present.

Book Description
Located where the Atlantic Ocean, Gulf of Mexico, and Caribbean Sea converge, the Florida Keys are distinctive for their rich and varied marine fauna. The Keys are home to nearly sixty taxonomic families of bivalves such as clams and mussels--roughly half the world's bivalve family diversity. The first in a series of three volumes on the molluscan fauna of the Keys and adjacent regions, Seashells of Southern Florida: Bivalves provides a comprehensive treatment of these bivalves, and also serves as a comparative anatomical guide to bivalve diversity worldwide. Paula Mikkelsen and Rüdiger Bieler cover more than three hundred species of bivalves, including clams, scallops, oysters, mussels, shipworms, jewel boxes, tellins, and many lesser-known groups. For each family they select an exemplar species and illustrate its shell and anatomical features in detail. They describe habitat and other relevant information, and accompany each species account with high-resolution shell photographs of other family members. Text and images combine to present species--to family-level characteristics in a complete way never before seen. The book includes fifteen hundred mostly color photographs and images of shells, underwater habitats, bivalves in situ, original anatomical and hinge drawings, scanning electron micrographs, and unique transparent--shell illustrations with major organ systems color-coded and clearly shown. Seashells of Southern Florida: Bivalves is the most complete guide to subtropical bivalves available. It is an essential tool for students and teachers of molluscan diversity and systematics, and an indispensable identification guide for collectors, scuba divers, naturalists, environmental consultants, and natural-resource managers.

Book Description
In this astonishingly assured, exquisitely crafted debut collection, Anthony Doerr takes readers from the African coast to the suburbs of Ohio, from sideshow pageantry to harsh wilderness survival, charting a vast and varied emotional landscape. Like the best storytellers, Doerr explores the human condition in all its manifestations: metamorphosis, grief, fractured relationships, and slowly mending hearts. Most dazzling is Doerr's gift for conjuring nature in both its beautiful abundance and crushing power. Some of his characters contend with tremendous hardship; some discover unique gifts; all are united by their ultimate deference to the mysteries of their respective landscapes.

Book Description
Shell structures are widely used in the fields of civil, mechanical, architectural, aeronautical, and marine engineering. Shell technology has been enhanced by the development of new materials and prefabrication schemes. Despite the mechanical advantages and aesthetic value offered by shell structures, many engineers and architects are relatively unacquinted with shell behaviour and design. This book familiarizes the engineering and architectural student, as well as the practicing engineer and architect, with the behaviour and design aspects of shell structures. Three aspects are presented: the Physical behaviour, the structural analysis, and the design of shells in a simple, integrated, and yet concise fashion. Thus, the book contains three major aspects of shell engineering: (1) physical understanding of shell behaviour; (2) use of applied shell theories; and (3) development of design methodologies together with shell design examples. The theoretical tools required for rational analysis of shells are kept at a modest level to give a sound grasp of the fundamentals of shell behaviour and, at the same time, an understanding of the related theory, allowing it to be applied to actual design problems. To achieve a physical understanding of complex shell behaviour, quantitative presentations are supplemented by qualitative discussions so that the reader can grasp the `physical feeling' of shell behaviour. A number of analysis and detailed design examples are also worked out in various chapters, making the book a useful reference manual. This book can be used as a textbook and/or a reference book in undergraduate as well as graduate university courses in the fields of civil, mechanical, architectural, aeronautical, and materials engineering. It can also be used as a reference and design-analysis manual for the practicing engineers and architects. The text is supplemented by a number of appendices containing tables of shell analysis and design charts and tables.

Book Description
Who among us hasn’t marveled at the diversity and beauty of shells? Or picked one up, held it to our ear, and then gazed in wonder at its shape and hue? Many a lifelong shell collector has cut teeth (and toes) on the beaches of the Jersey Shore, the Outer Banks, or the coasts of Sanibel Island. Some have even dived to the depths of the ocean. But most of us are not familiar with the biological origin of shells, their role in explaining evolutionary history, and the incredible variety of forms in which they come. Shells are the external skeletons of mollusks, an ancient and diverse phylum of invertebrates that are in the earliest fossil record of multicellular life over 500 million years ago. There are over 100,000 kinds of recorded mollusks, and some estimate that there are over amillion more that have yet to be discovered. Some breathe air, others live in fresh water, but most live in the ocean. They range in size from a grain of sand to a beach ball and in weight from a few grams to several hundred pounds. And in this lavishly illustrated volume, they finally get their full due. The Book of Shells offers a visually stunning and scientifically engaging guide to six hundred of the most intriguing mollusk shells, each chosen to convey the range of shapes and sizes that occur across a range of species. Each shell is reproduced here at its actual size, in full color, and is accompanied by an explanation of the shell’s range, distribution, abundance, habitat, and operculum—the piece that protects the mollusk when it’s in the shell. Brief scientific and historical accounts of each shell and related species include fun-filled facts and anecdotes that broaden its portrait. The Matchless Cone, for instance, or Conus cedonulli, was one of the rarest shells collected during the eighteenth century. So much so, in fact, that a specimen in 1796 was sold for more than six times as much as a painting by Vermeer at the same auction. But since the advent of scuba diving, this shell has become far more accessible to collectors—though not without certain risks. Some species of Conus produce venom that has caused more than thirty known human deaths. The Zebra Nerite, the Heart Cockle, the Indian Babylon, the Junonia, the Atlantic Thorny Oyster—shells from habitats spanning the poles and the tropics, from the highest mountains to the ocean’s deepest recesses, are all on display in this definitive work.
