Mitochondria in plants, as in other eukaryotes, play an essential role in the cell as the major producers of ATP via oxidative phosphorylation. However, mitochondria also play crucial roles in many other aspects of plant development and performance, and possess an array of unique properties which allow them to interact with the specialized features of plant cell metabolism. The two main themes running through the book are the interconnection between gene regulation and protein function, and the integration of mitochondria with other components of plant cells.

The book begins with an overview of the dynamics of mitochondrial structure, morphology and inheritance. It then discusses the biogenesis of mitochondria, the regulation of gene expression, the mitochondrial genome and its interaction with the nucleus, and the targeting of proteins to the organelle. This is followed by a discussion of the contributions that mutations, involving mitochondrial proteins, have made to our understanding of the way the organelle interacts with the rest of the plant cell, and the new field of proteomics and the discovery of new functions. Also covered are the pathways of electron transport, with special attention to the non-phosphorylating bypasses, metabolite transport, and specialized mitochondrial metabolism.

In the end, the impact of oxidative stress on mitochondria and the defense mechanisms, that are employed to allow survival, are discussed. This book is for the use of advanced undergraduates, graduates, postgraduates, and beginning researchers in the areas of molecular and cellular biology, integrative biology, biochemistry, bioenergetics, proteomics and plant and agricultural sciences.

Part of the What Everyone Needs to Know (R) series, David Day's book on Antarctica examines the most forbidding and formidably inaccessible continent on Earth. Antarctica was first discovered by European explorers in 1820, and for over a century following this, countries competed for the frozen land's vast marine resources-namely, the skins and oil of seals and whales. Soon the entire territory played host to competing claims by rival nations. The Antarctic Treaty of 1959 was meant to end this contention, but countries have found other means of extending control over the land, with scientific bases establishing at least symbolic claims. Exploration and drilling by the United States, Great Britain, Russia, Japan, and others has led to discoveries about the world's climate in centuries past-and in the process intimations of its alarming future. Delving into the history of the continent, Antarctic wildlife, arguments over governance, underwater mountain rangers, and the continent's use in predicting coming global change, Day's work sheds new light on a territory that, despite being the coldest, driest, and windiest continent in the world, will continue to be the object of intense speculation and competition.

J.R.R. Tolkien's The Lord of the Rings, The Hobbit and The Silmarillion are some of the greatest tales of good versus evil ever told.

Here in his latest book, best-selling author and Tolkien expert David Day explores Tolkien's portrayal of evil, and the sources that inspired his work: from myth, literature and history.

This volume is an in-depth and exquisitely illustrated guide to the Second Age of Middle-earth, one of the least-explored periods of Arda's history. The Illustrated World of Tolkien: The Second Age, is the follow up companion to the best-selling The Illustrated World of Tolkien, and gathers together artwork, charts, and fascinating and scholarly writing from renowned Tolkien expert David Day. Exploring the languages, poetry and elements of the heroic ages of Norse, Greek and Roman mythologies that may have influenced Tolkien's writing, it is a reference guide for any fan of Tolkien's work, Tolkien's world and the imaginative brilliance his vision inspired. The Second Age is made up of two great narrative channels: on the one hand the rise and cataclysmic downfall of the island-kingdom of Númenor and its aftermath, and on the other the forging of the Rings of Power and the rise to power of the new dark lord. Tolkien's sources for his Second Age are, of course, as rich and varied as ever and this book delves into some of these influences and shows how the power of Tolkien's imagination is manifest even in the lesser-known parts of his legendarium.

The key question this book addresses is how to identify and create optimal conditions for the kind of learning and development that is especially important for effectively functioning in the 21st century. Taking a new approach to this long-debated issue, it looks at how a design research-based science of learning (with its practical models and related design research) can provide insights and integrated models of how human beings actually function and grow in the social dynamics of educational settings with all their affordances and constraints. More specifically: How can specific domains or subject matters be taught for broad intellectual development? How can technology be integrated in enhancing human functioning? How can the social organization of classroom learning be optimized to create social norms for promoting deep intellectual engagement and personal growth? Part I is concerned with broad conceptual and technical issues regarding cultivating intellectual potential, with a focus on how design research might fill in an important a niche in addressing these issues. Part II presents specific design work in terms of design principles, models, and prototypes.

This book explores the ways in which preachers embody their messages - in their own person, in the words they use, in employing objects, pictures, the arts and the responses of those hearing the sermon. Suitable for most theological traditions, Embodying the Word is aimed at a broad range of Christian denominations. Although related to the author's previous work, A Preaching Workbook, this volume will be complementary.

Every Sunday all over the world people rise up and claim to speak in the name of God. It is an astonishing thing to do and an astonishing claim to make. It is small wonder that the sermon has been the focus of debate, discussion and investigation. It has been dismissed as irrelevant in today's culture and has become the butt of numerous jokes and caricatures. Yet the claim persists that these human words in some way can become God's message to these hearers. This collection of twenty-nine articles by international experts in the area of homiletics coincides with the revival of interest in preaching over the last twenty-five years. It is practical without being merely tips for preachers; and it offers the necessary theoretical discussion for anyone who wants to take the art of preaching seriously. No important issue has been omitted and, taken as a whole, the book constitutes a first class introduction to the principles, processes, context and theology of preaching. Contributors include: Walter Brueggemann, David Buttrick, Fred Craddock, Edward Farley, John Killinger, Richard Lischer, Thomas Long, Elaine Lawless, Jolyon Mitchell, Cheryl Sanders and Thomas Troeger.
