Direct coal liquefaction, a synthetic liquid fuel process, is one of the major developmental alternatives for meeting the anticipated fuel demands for the twenty-first century. This work provides a retrospective assessment of past attempts in this century to develop synthetic liquid fuel and applies the findings to produce reliable and pertinent data for the future. Retrospective technology assessment, a recent methodological invention, is used by the authors to analyze the past synthetic liquid fuel programs and the reasons for their failures. Bringing to bear four different perspectives--economic, technological, policy, and historical--the authors draw broad conclusions that will help guide the next development effort in the United States.

This unique textbook combines traditional geometry presents a contemporary approach that is grounded in real-world applications. It balances the deductive approach with discovery learning, introduces axiomatic, Euclidean and non-Euclidean, and transformational geometry. The text integrates applications and examples throughout. The Third Edition offers many updates, including expaning on historical notes, Geometry and Its Applications is a significant text for any college or university that focuses on geometry's usefulness in other disciplines. It is especially appropriate for engineering and science majors, as well as future mathematics teachers. The Third Edition streamlines the treatment from the previous two editions Treatment of axiomatic geometry has been expanded Nearly 300 applications from all fields are included An emphasis on computer science-related applications appeals to student interest Many new excercises keep the presentation fresh
