Available in PDF, EPUB and Kindle. Book excerpt: Examining portraits of black people over the past two centuries, Cutting a Figure argues that these images should be viewed as a distinct category of portraiture that differs significantly from depictions of people with other racial and ethnic backgrounds. The difference, Richard Powell contends, lies in the social capital that stems directly from the black subject’s power to subvert dominant racist representations by evincing such traits as self-composure, self-adornment, and self-imagining. Powell forcefully supports this argument with evidence drawn from a survey of nineteenth-century portraits, in-depth case studies of the postwar fashion model Donyale Luna and the contemporary portraitist Barkley L. Hendricks, and insightful analyses of images created since the late 1970s. Along the way, he discusses major artists—such as Frédéric Bazille, John Singer Sargent, James Van Der Zee, and David Hammons—alongside such overlooked producers of black visual culture as the Tonka and Nike corporations. Combining previously unpublished images with scrupulous archival research, Cutting a Figure illuminates the ideological nature of the genre and the centrality of race and cultural identity in understanding modern and contemporary portraiture.

Download or read book The Delft Sand Clay and Rock Cutting Model written by S.A. Miedema and published by IOS Press. This book was released on 2014-10-29 with total page 572 pages. Available in PDF, EPUB and Kindle. Book excerpt: Sand, clay and rock have to be excavated for a variety of purposes, such as dredging, trenching, mining (including deep sea mining), drilling, tunnel boring and many other applications. Many excavations take place on dry land, but they are also frequently required in completely saturated conditions, and the methods necessary to accomplish them consequently vary widely. This book provides an overview of cutting theories. It begins with a generic model, valid for all types of soil (sand, clay and rock), and continues with the specifics of dry sand, water-saturated sand, clay, atmospheric rock and hyperbaric rock. Small blade angles and large blade angles are discussed for each soil type, and for each case considered the equations/model for cutting forces, power and specific energy are given. With models verified by laboratory research, principally from the Delft University of Technology, and data from other recognized sources, this book will prove an invaluable reference for anybody whose work involves major excavations of any kind.

Download or read book Faceting History Cutting Diamonds and Colored Stones written by Glenn Klein and published by Xlibris Corporation. This book was released on 2005-10-13 with total page 242 pages. Available in PDF, EPUB and Kindle. Book excerpt: The author of, "FACETING HISTORY: CUTTING DIAMONDS AND COLORED STONES" has for a long time had a deep interest in learning how the early faceters (cutters) of diamonds and colored gemstones were able to complete their work. What methods did they use? What equipment did they have to make success possible? How soon did they discover how to complete the many phases necessary to accomplish their work? How did the equipment and methods differ between fashioning diamonds and faceting colored stones? These are just a few of the questions that the author wanted to find the answers for. In looking for answers to these and other questions, the author found that there were bits and pieces of information available in many previous books, but there was not a good book available that would answer most of his questions. Upon hearing the author ́s remarks about this fact, one of the librarians at the wonderful library located at the Gemological Institute of America ́s Carlsbad campus said that if such a book was not available, "maybe you should write the book!" Well, the author had been thinking of doing just that, but the remark caused the author to see the light and agree to get started on the project. Little did he know then that the project would require many months of eight hour days over seven day weeks to get the book completed. He decided to write a book that would answer these and other related questions that he had. The thought also occurred to him that such a book would be a valuable volume to be placed in libraries of individual faceters around the world. He realized that such a book would also be of great value to anyone who works behind a Jewelry store counter. A successful sales person is one who is knowledgeable about the products that they are selling. A book of faceting information would be extremely valuable if read and re-read from time to time. A customer in the Jewelry store will no doubt be favorably impressed by a sales presentation that is made with the use of interesting and informative information about diamonds and the various colored gemstones. The customer will be convinced that the sales person knows about what they are talking. The author has spent nearly three years on the project of researching the GIA library and other libraries, along with the extensive personal library of gemstone related books that he personally possesses. Many conflicting reports were noted in his study. He has made the statements in his book reflect the most commonly accepted opinions, of the most respected authors ́ works that he has found in his research. History is only obtainable from the earlier works of other authors. We cannot go back to the long past centuries ourselves, to see first hand what really happened and when it happened. A study of faceting history requires making the best choices of the information that is available. This completed book answers questions as to why the fashioning of diamonds was/is so different from the faceting of colored gemstones. The book compares the needed equipment and the methods that have brought the greatest successes. In addition, a great deal of other information connected to faceting is included. There are seven chapters in the book and there are over 125 photographs of the early equipment and methods that were used. The photographs show the faceters, the workroom conditions, and the tools and equipment that they used to complete beautiful and lasting gemstones. The book chapters are titled: An Introduction to Faceting, Early Man ́s Stone Appreciation, Diamond Fashioning Procedure and Equipment, Colored Stone Faceting Procedure and Equipment, The Evolution of Cut Designs, Famous and Historic Gemstones, Sources of Diamond and Colored Stone Rough, and lastly, Advances in Faceting Over the Past One Hundred Years. By books end, the reader will be well informed as to what is r
