Book Description
Man was cutting, carving and polishing gems long before he began to leave written records of his doings. Many Museums have countless examples of the lapidary work done by those artisans and artists, who wrought from raw materials, with exceedingly primitive equipment, objects of art that our modern workers would be hard taxed to surpass. Today, in the Far East, native artisans with hand or foot driven wheels are producing perfect polishes on difficult gems, showing workmanship of which we amateurs with full complement of tools may well be envious. Gem cutting is only one of many arts that are old. Ceramics, wood working, metal working and so forth are old arts. The thing that is peculiar is that these other arts all have their extensive literatures. One may go to any public library and find many volumes on any of these subjects except gem cutting. These volumes are all-revealing, authoritative and detailed. But the subject of gem cutting is shrouded in mystery. Few have written even in generalities on the subject. The Author, several years ago, conducted a search for such literature. He found absolutely nothing. Much later he learned of and borrowed, a copy of Oliver Byrnes, “Handbook for the Mechanic, Artisan and Engineer” and found in it an exceedingly interesting chapter on gem cutting. But the volume was written about 75 years ago, probably had a very limited circulation, was never reprinted, and not one library in fifty ever heard of it. That is the only volume the Author has ever found that treats even briefly of gem cutting. This excludes of course such texts as “The Gem Cutters Craft” by Leopold Cleremont which have chapters on the technique of cutting, but that treat of it so generally that they cannot be used as instructions. The art for some reason has always been passed down from generation to generation by apprenticeship only. When the Author began the above mentioned investigation he was told “The cutting of gems can be learned only through an apprenticeship.” There is no desire here to picture the art as an easy one to learn nor to minimize the skill that is shown by the work of the professional lapidaries, nor to intimate that the professional could, if he would, reveal all his secrets in one brief volume. The desire is to lift the cloud of mystery that has always surrounded the operation and show that actually there is nothing mysterious in the practices of the profession, but only certain basic rules, which, if obeyed, will bring definite results. It is hoped that the instructions herein given are sufficiently explicit that the beginner in the work will have no especial difficulties. It is hoped also that they are not so tedious but that they will be readable by those who do not propose to cut gems but who are, nevertheless, interested in the operation.

Multi-Storey Precast Concrete Framed Structures
Author: Kim S. Elliott
Publisher: John Wiley & Sons
ISBN: 1118587359
Category : Technology & Engineering
Languages : en
Pages : 1
Book Description
Precast reinforced and prestressed concrete frames provide a high strength, stable, durable and robust solution for any multi-storey structure, and are widely regarded as a high quality, economic and architecturally versatile technology for the construction of multi-storey buildings. The resulting buildings satisfy a wide range of commercial and industrial needs. Precast concrete buildings behave in a different way to those where the concrete is cast in-situ, with the components subject to different forces and movements. These factors are explored in detail in the second edition of Multi-Storey Precast Concrete Framed Structures, providing a detailed understanding of the procedures involved in precast structural design. This new edition has been fully updated to reflect recent developments, and includes many structural calculations based on EUROCODE standards. These are shown in parallel with similar calculations based on British Standards to ensure the designer is fully aware of the differences required in designing to EUROCODE standards. Civil and structural engineers as well as final year undergraduate and postgraduate students of civil and structural engineering will all find this book to be thorough overview of this important construction technology.

Genre in a Changing World
Author: Charles Bazerman
Publisher: Parlor Press LLC
ISBN: 1643170015
Category : Language Arts & Disciplines
Languages : en
Pages : 486
Book Description
Genre studies and genre approaches to literacy instruction continue to develop in many regions and from a widening variety of approaches. Genre has provided a key to understanding the varying literacy cultures of regions, disciplines, professions, and educational settings. GENRE IN A CHANGING WORLD provides a wide-ranging sampler of the remarkable variety of current work. The twenty-four chapters in this volume, reflecting the work of scholars in Europe, Australasia, and North and South America, were selected from the over 400 presentations at SIGET IV (the Fourth International Symposium on Genre Studies) held on the campus of UNISUL in Tubarão, Santa Catarina, Brazil in August 2007—the largest gathering on genre to that date. The chapters also represent a wide variety of approaches, including rhetoric, Systemic Functional Linguistics, media and critical cultural studies, sociology, phenomenology, enunciation theory, the Geneva school of educational sequences, cognitive psychology, relevance theory, sociocultural psychology, activity theory, Gestalt psychology, and schema theory. Sections are devoted to theoretical issues, studies of genres in the professions, studies of genre and media, teaching and learning genre, and writing across the curriculum. The broad selection of material in this volume displays the full range of contemporary genre studies and sets the ground for a next generation of work.
