Download or read book Siwa written by Margaret M. Vale and published by American University in Cairo Press. This book was released on 2015-01-01 with total page 302 pages. Available in PDF, EPUB and Kindle. Book excerpt: Siwa is a remote oasis deep in the heart of the Egyptian desert near the border with Libya. Until an asphalt road was built to the Mediterranean coast in the 1980s, its only links to the outside world were by arduous camel tracks. As a result of this isolation, Siwa developed a unique culture manifested in its crafts of basketry, pottery, and embroidery and in its styles of costume and silverwork. The most visible and celebrated example of this was the silver jewelery that was worn by women in abundance at weddings and other ceremonies. Based on conversations with women and men in the oasis and with reference to old texts, this book describes the jewelery and costume at this highpoint of Siwan culture against the backdrop of its date gardens and springs, social life, and dramatic history. It places the women's jewelery, costume, and embroidery into social perspective, and describes how they were used in ceremonies and everyday life and how they were related to their beliefs and attitudes to the world. The book also describes how, in the second half of the twentieth century, the arrival of the road and of television brought drastic change, and the oasis was exposed to the styles and fashions of the outside world and how the traditional silver ornaments were gradually replaced by gold.
Download or read book Wetland Environments written by James S. Aber and published by John Wiley & Sons. This book was released on 2012-08-24 with total page 628 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wetlands - swamp, marsh, bayou, tundra and bog - are places that are rarely visited and often misunderstood but they have, in fact, conspicuous roles in the physical, biological and cultural geography of the world. They are intrinsically beautiful environments where one may see the natural and essential values in the interaction of water, soil, vegetation, wildlife, and humans. Wetlands occur at the confluence of unique terrestrial, hydrological and climatic conditions that give rise to some of the most biodiverse regions of the world. They also play vital roles in the cycling and storage of key nutrients, materials and energy through the Earth?s system. A complete study of wetland environments requires the assessment of their physical and biological attributes, properties and functions of these ecosystems, and the economic, political and social aspects that mediate their use globally. A systems approach is taken throughout this book which emphasizes the interactions between these elements of wetland ecosystems. Moreover, selected case studies from across the world are used to illustrate wetland characteristics and circumstances. This book is intended to foster a greater awareness and appreciation of wetlands, promote a culture of conservation and wise management, and spread the knowledge that wetlands are important, indeed crucial, elements of the global environment. Our attempts to understand, manage and enhance wetlands in the twenty-first century are part of the larger effort to maintain a sustainable Earth. Readership: Introductory or intermediate level undergraduates taking courses on wetland environments Additional resources for this book can be found at: www.wiley.com/go/aber/wetland
Download or read book Gemmology written by P. G. Read and published by Elsevier. This book was released on 2013-10-22 with total page 375 pages. Available in PDF, EPUB and Kindle. Book excerpt: Gemmology is a text for students preparing for the Gemmological Association's Preliminary and Diploma examinations. The book is more expansive and up-to-date than the author's earlier book, Beginner's Guide to Gemmology. The book deals with the practical and theoretical sides of gemmology. Tracing the background and science of gemmology, the book covers the gem material, geological formation, and occurrence of gemstones on the earth. The composition of gemstones from the atoms, elements, molecules, and compounds comprising them is analyzed, and the relationship between chemical composition and durability of the stone is explained. The basics of crystallography is mentioned as a tool toward understanding gemmology after which cleavage, parting, and fracture are done. A gemstone's durability and hardness and how the latter influences engineering tests and the mining techniques are compared. An important test technique to identify unmounted stones is the measure of specific gravity using displacement measurement methods and hydrostatic methods. After more descriptive details are given in identification of gemstones, whether these are synthetic or simulants, through a comprehensive explanation of the materials found in these other gemstones, the fashioning, through shaping or polishing, of gemstones is explained. Emphasis is given on the critical angle in which light rays pass in different rock densities, and then the cutting styles, gemstone polishing, and grading are discussed. Students studying for the Gemmological Association's Preliminary and Diploma examinations, jewelers, lapidarists, and diamond cutters, as well as those engaged in the hobby of gemmology, will find this book helpful and full of information toward their endeavors and hobbies.
Download or read book Shell written by Ingrid Thomas and published by Thames and Hudson. This book was released on 2007-10-30 with total page 264 pages. Available in PDF, EPUB and Kindle. Book excerpt: The most complete, beautifully illustrated volume ever published on the fascinating world of the shell and its uses in design and decoration. Shells have captivated humans through the ages and been put to a wide range of uses—sharpened into tools, ground to make medicines, blown to make music. Shells were used as currency from the Americas through Africa to Asia, and worn as amulets to bring fertility, good fortune, or protection from the evil eye. Above all, the beauty of shells has fired the imaginations of artists and craftsmen, and their work forms the heart of this book. • Shells and mother-of-pearl have been carved to make buttons, jewelry, and delicate inlay work. • Shells are a universal element of human adornment, from the simplest string of beads to shell designs in gold and precious stones. • Mythological, symbolic, decorative, botanical, or fantastical: shells are a recurring theme in visual art. • Shells have featured in architectural ornament since ancient times, and in the twentieth century inspired the forms of landmark buildings. • Shells have inspired centuries of exquisite invention in silverware, ceramics, glass, textiles, furniture, and fashion. Shells were among the exotic treasures brought back from the voyages of discovery. By 1796 the mania for shells was such that a single shell raised six times the sum paid for a Vermeer painting at an estate auction in The Hague. Conchology and shell collecting remain hugely popular today, and the author explains how they can be pursued responsibly, without harming our precious marine environments. 500+ color photographs and illustrations.
Download or read book Tears of Mermaids written by Stephen G. Bloom and published by St. Martin's Press. This book was released on 2011-05-10 with total page 401 pages. Available in PDF, EPUB and Kindle. Book excerpt: A round, luminescent pearl is the simplest and most perfect gem. Columbus sought—and found—this precious jewel coveted by his Spanish sovereigns, sparking popularity throughout Europe. Fashion icons Jacqueline Kennedy, Princess Grace, and Michelle Obama cherished them, making them iconic. And designer Coco Chanel raised them to new heights, bringing pearls— fake and real—to women everywhere. In Tears of Mermaids, Stephen G. Bloom travels 30,000 miles in an effort to trace a single pearl—from the moment a diver off the coast of Australia scoops an oyster containing a single luminescent pearl from the ocean floor to the instant a woman fastens the clasp of a strand containing the same orb. Bloom chronicles the never-before-told saga of the global pearl trade by gaining access to clandestine outposts in China, the Philippines, French Polynesia and Australia. He infiltrates high-tech pearl farms guarded by gun-toting sentries, farms for pearls in rural China, and even goes backstage at Christie's for a fast and furious auction of the most expensive pearl ever sold. Teeming with rogue humor and uncanny intelligence, Tears of Mermaids weaves a nonstop detective story whose main character is the world's most enduring jewel.
Download or read book The Pearl King written by Robert Lehane and published by Boolarong Press. This book was released on 2014-06-23 with total page 430 pages. Available in PDF, EPUB and Kindle. Book excerpt: Born on a Hunter estuary, NSW, island in 1857, James Clark was orphaned at age two, arrived penniless in Brisbane ten years later, and never looked back. Starting out in Torres Strait at 23, he became the dominant figure in Australia’s pearlshelling industry, The Pearl King. Then, with a young partner, he built one of the nation’s biggest pastoral companies. He ran an oyster business in Moreton Bay that supplied gourmet markets as far away as Perth, and was prominent in Queensland’s yachting and horseracing fraternities. Entrepreneurial, generous, with a reputation for straight-shooting, he lived life to the full.
Download or read book The Pearl shellers of Torres Strait written by Regina Ganter and published by Melbourne University. This book was released on 1994 with total page 340 pages. Available in PDF, EPUB and Kindle. Book excerpt: In an ethnically stratified work force, Japanese, South Sea Islander, Torres Strait Islander and Aboriginal divers brought up from the sea floor the shell that produced mother-of-pearl, and sometimes pearls. Many men died at this dangerous work. This was an industry that could have given the indigenous peoples of Torres Strait an occupation that preserved their identity and independence. Yet in spite of a co-operative lugger scheme that operated fairly successfully in the early twentieth century, a real independence was not achieved. And a resource that could have been conserved by small-scale indigenous harvesting was depleted time and again by the colonial practices of resource-raiding and mass extraction. Regina Ganter charts the progress of pearl-shelling from its heyday through its several crises resulting from overfishing to its present cautious management. The book is greatly enhanced by the oral testimony of divers and boat-owners.
Download or read book Goods and Services of Marine Bivalves written by Aad C. Smaal and published by Springer. This book was released on 2018-11-26 with total page 598 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this open access book is to review and analyse the goods and services of bivalve shellfish. How they are defined, what determines the ecological functions that are the basis for the goods and services, what controversies in the use of goods and services exist, and what is needed for sustainable exploitation of bivalves from the perspective of the various stakeholders. The book is focused on the goods and services, and not on impacts of shellfish aquaculture on the benthic environment, or on threats like biotoxins; neither is it a shellfish culture handbook although it can be used in evaluating shellfish culture. The reviews and analysis are based on case studies that exemplify the concept, and show the strengths and weaknesses of the current applications. The multi-authored reviews cover ecological, economic and social aspects of bivalve goods and services. The book provides new insights for scientists, students, shellfish producers, policy advisors, nature conservationists and decision makers. This book is open access under the CC BY license.
Download or read book An Archaeology of Australia Since 1788 written by Susan Lawrence and published by Springer Science & Business Media. This book was released on 2010-10-21 with total page 433 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume provides an important new synthesis of archaeological work carried out in Australia on the post-contact period. It draws on dozens of case studies from a wide geographical and temporal span to explore the daily life of Australians in settings such as convict stations, goldfields, whalers' camps, farms, pastoral estates and urban neighbourhoods. The different conditions experienced by various groups of people are described in detail, including rich and poor, convicts and their superiors, Aboriginal people, women, children, and migrant groups. The social themes of gender, class, ethnicity, status and identity inform every chapter, demonstrating that these are vital parts of human experience, and cannot be separated from archaeologies of industry, urbanization and culture contact. The book engages with a wide range of contemporary discussions and debates within Australian history and the international discipline of historical archaeology. The colonization of Australia was part of the international expansion of European hegemony in the eighteenth and nineteenth century. The material discussed here is thus fundamentally part of the global processes of colonization and the creation of settler societies, the industrial revolution, the development of mass consumer culture, and the emergence of national identities. Drawing out these themes and integrating them with the analysis of archaeological materials highlights the vital relevance of archaeology in modern society.
