The theory of one-dimensional ergodic operators involves a beautiful synthesis of ideas from dynamical systems, topology, and analysis. Additionally, this setting includes many models of physical interest, including those operators that model crystals, disordered media, or quasicrystals. This field has seen substantial progress in recent decades, much of which has yet to be discussed in textbooks. Beginning with a refresher on key topics in spectral theory, this volume presents the basic theory of discrete one-dimensional Schrödinger operators with dynamically defined potentials. It also includes a self-contained introduction to the relevant aspects of ergodic theory and topological dynamics. This text is accessible to graduate students who have completed one-semester courses in measure theory and complex analysis. It is intended to serve as an introduction to the field for junior researchers and beginning graduate students as well as a reference text for people already working in this area. It is well suited for self-study and contains numerous exercises (many with hints).
Gold has traditionally been regarded as inactive as a catalytic metal. However, the advent of nanoparticulate gold on high surface area oxide supports has demonstrated its high catalytic activity in many chemical reactions. Gold is active as a heterogeneous catalyst in both gas and liquid phases, and complexes catalyse reactions homogeneously in solution. Many of the reactions being studied will lead to new application areas for catalysis by gold in pollution control, chemical processing, sensors and fuel cell technology. This book describes the properties of gold, the methods for preparing gold catalysts and ways to characterise and use them effectively in reactions. The reaction mechanisms and reasons for the high activities are discussed and the applications for gold catalysis considered. Sample Chapter(s). Chapter 1: Introduction to Catalysis (892 KB). Contents: Introduction to Catalysis; The Physical and Chemical Properties of Gold; Physical Properties and Characterisation of Small Gold Particles; Preparation of Supported Gold Catalysts; Chemisorption of Simple Molecules on Gold; Oxidation of Carbon Monoxide; The Selective Oxidation of Carbon Monoxide; Selective Oxidation; Reactions Involving Hydrogen; The WaterOCoGas Shift; Reactions of Environmental Importance; Catalysis by Soluble and Supported Gold Compounds; Miscellaneous Reactions Catalysed by Gold; Commercial Applications. Readership: Postgraduate level researchers in academia and industry, as well as general readers.
David, The Man of the Heart is a book of essays exploring the impact and implications of the character of King David as revealed through a study of key Psalms. This book is not a chronological biography, but rather an exploration of King David's life as a type of Christ as the Shepherd, the Soldier, the Sovereign, the Sinner, and the Singer. At the same time, the reader is introduced to valuable guidelines to a study of the Psalms.
A study of what the Bible has to say about the essential nature of God, that being 'love', which compels him to do whatever it takes to draw us to himself.
The Heart of David Journal Volume 8: Leading with Vision, Passion, and Wisdom With a continual passionate pursuit after the heart of God, David Mayorga, once again, releases some compelling revelatory knowledge and present-day truths that will enlighten and empower the servant of Jesus who has been seeking more of God's incredible presence. In this new volume 8, the writer has found himself pressing in for a deeper understanding of the person of Jesus and His calling upon all who have decided to follow Him without regrets, retreats, and reserves. It is your time to allow God to take you to places you have never seen and never walked on! As you read, may the Spirit of God lead your heart and mind into the realm of God. Get ready to be immersed in higher levels of His glory!
From award-winning comedian, director, writer, and producer David Steinberg comes the totally original, utterly blasphemous, and hysterically funny memoir of a young man who emerged from a traditional Jewish childhood to become an international star -- all because, it seems, he kept God in stitches. David Steinberg was raised in Winnipeg, Canada, by parents who expected little from him. And no wonder. Instead of studying Talmud in order to become a rabbi, he chose to major in Martin and Lewis with a minor in basketball. As David imagines the story of his life (since his success otherwise makes no sense), God one day spotted him on the playground and decided that this young man with no ambition could go far with His help. Sure enough, God soon had David on network TV and Broadway, and selling out nightclubs across the country -- as well as being pursued by hot starlets. The Book of David is David Steinberg's hilarious trip down memory lane, assuming that the lane has a biblical address. This wild riff on the Old Testament is guaranteed laughter.
