Extensively tested in schools and colleges, this modular-based book provides a progressive introduction to supply and demand analysis and the theory of the firm, and shows how it can be applied to real economic problems. Its generous use of diagrams, examples and past examination questions helps the student understand and apply the basic principles. Each topic is developed through the use of data response and multiple-choice questions. No previous knowledge of the subject is assumed, but the text progresses through the material to achieve the necessary standard for examination success.

DEFINITION AND NOMENCLATURE A Stirling engine is a mechanical device which operates on a closed regenerative thermodynamic cycle with cyclic compression and expansion of the working fluid at different temperature levels. The flow of working fluid is controlled only by the internal volume changes, there are no valves and, overall, there is a net conversion of heat to work or vice-versa. This generalized definition embraces a large family of machines with different functions; characteristics and configurations. It includes both rotary and reciprocating systems utilizing mechanisms of varying...

The rapidly expanding use of very low temperatures in research and high technology during the last several decades and the concurrent high degree of activity in cryogenic engineering have mutually supported each other, each improvement in refrigeration technique making possible wider oppor tunities for research and each new scientific discovery creating a need for a refrigerator with special features. In this book, Professor Walker has provided us with an excellent exposition of the achievements of this period, the fundamental principles involved, and a critical examination of the many...

Graham Walker boldly recasts the debate over issues like constitutional interpretation and judicial review, and challenges contemporary thinking not only about specifically constitutional questions but also about liberalism, law, justice, and rights. Walker targets the "skeptical" moral nihilism of leading American judges and writers, on both the political left and right, charging that their premises undermine the authority of the Constitution, empty its moral words of any determinate meaning, and make nonsense of ostensibly normative theories. But he is even more worried about those who...
