Designing the perfect mold is probably the most challenging task in plastics processing, especially in injection molding. The mold determines the... quality, performance, and the profitability of a plastic part. Neither modern computer technology nor sophisticated CAE software can substitute the experience of the practicing mold engineer. This is why the Gastrow is so special to plastics engineers: 130 mold designs are presented in this extensively revised edition of the great classic in mold making. Each of the case studies was actually built, tested, and run successfully in production. The book is written by practitioners, describing problem solving in the design and the manufacture of injection molds. The wealth of information includes rules of thumb, design details, and practical tips invaluable for everyone involved in this field.

Gas Turbine Engines gives a modern introduction to aircraft gas turbine engines intended to provide the fundamentals of turbines to maintenance... personnel and pilots either to simply understand the basics of turbines, or as a primer before studying the details of the specific engines you will be involved with. Easy to understand, step by step descriptions, with many color drawings and diagrams.

In recent years the gas turbine, in combination with the steam turbine, has played an ever-increasing role in power generation. Despite the rapid... advances in both output and efficiency, the basic theory of the gas turbine has remained unchanged. The layout of this new edition is broadly similar to the original, but greatly expanded and updated, comprising an outline of the basic theory, aerodynamic design of individual components, and the prediction of off-design performance. The addition of a chapter devoted to the mechanical design of gas turbines greatly enhances the scope of the book.

This groundbreaking study illuminates the Egyptian experience of modernity by critically analyzing the foremost medium through which it was articulated:... history. The first comprehensive analysis of a Middle Eastern intellectual tradition, Gatekeepers of the Past examines a system of knowledge that replaced the intellectual and methodological conventions of Islamic historiography only at the very end of the nineteenth century. Covering more than one hundred years of mostly unexamined historucal literature in Arabic, Yoav Di-Capua explores Egyptian historical thought, examines the careers of numerous critical historians, and traces this tradition's uneasy relationship with colonial forms of knowledge as well as with the post-colonial state.

Gatekeeping is one of the media’s central roles in public life: people rely on mediators to transform information about billions of events into a... manageable number of media messages. This process determines not only which information is selected, but also what the content and nature of messages, such as news, will be. Gatekeeping Theory describes the powerful process through which events are covered by the mass media, explaining how and why certain information either passes through gates or is closed off from media attention. This book is essential for understanding how even single, seemingly trivial gatekeeping decisions can come together to shape an audience’s view of the world, and illustrates what is at stake in the process.
