The shimmering, cloud-covered planet of Venus conceals a wondrous secret: the strikingly beautiful yet deadly world of Amtor. In Amtor, cities of immortal beings flourish in giant trees reaching thousands of feet into the sky; ferocious beasts stalk the wilderness below; rare flashes of sunlight precipitate devastating storms; and the inhabitants believe their world is saucer-shaped with a fiery center and an icy rim. Stranded on Amtor after his spaceship crashes, astronaut Carson Napier is swept into a world where revolution is ripe, the love of a princess carries a dear price, and death can come as easily from the blade of a sword as from the ray of a futuristic gun.

Advances in digital technology led to the development of digital x-ray detectors that are currently in wide use for projection radiography, including Computed Radiography (CR) and Digital Radiography (DR). Digital Imaging Systems for Plain Radiography addresses the current technological methods available to medical imaging professionals to ensure the optimization of the radiological process concerning image quality and reduction of patient exposure. Based on extensive research by the authors and reference to the current literature, the book addresses how exposure parameters influence the diagnostic quality in digital systems, what the current acceptable radiation doses are for useful diagnostic images, and at what level the dose could be reduced to maintain an accurate diagnosis. The book is a valuable resource for both students learning the field and for imaging professionals to apply to their own practice while performing radiological examinations with digital systems.

Too often in the life of the church, theological reflection and the practical matters of leading and serving have been considered independently. The result has been the impoverishment of both Christian faith and Christian practice. In this groundbreaking book Ray Anderson reflects theologically and practically on preaching, worship, ethics, social justice, therapy, family, homosexuality, burnout in ministry, reconciliation in relationships and theological education itself. The result is The Shape of Practical Theology, a new and renewing foundation for engaging in Christian ministry. Anderson lays out his threefold goal as follows: - to define more clearly the shape of practical theology as truly a theological enterprise rather than mere mastery of skills and methods - to demonstrate the praxis of practical theology as critical engagement with the interface between the word of God as revealed through Scripture and the work of God taking place in and through the church in the world - to deal with practical pastoral theology from the perspective of those who are on the "field of play" of life and ministry, where preaching, counseling and teaching does affect for many persons the outcome of the game Illuminated by stimulating discussion and helpful case studies, The Shape of Practical Theology is aimed at seminary students, at Christian educators, and at working pastors and counselors. Anderson's work, fascinating and fruitful, brings together the Word of God with the Spirit of God in the ever-changing context of real-life ministry.
