This is a book written primarily for graduate students and early researchers in the fields of Analysis and Partial Differential Equations (PDEs). Coverage of the material is essentially self-contained, extensive and novel with great attention to details and rigour. The strength of the book primarily lies in its clear and detailed explanations, scope and coverage, highlighting and presenting deep and profound inter-connections between different related and seemingly unrelated disciplines within classical and modern mathematics and above all the extensive collection of examples, worked-out and hinted exercises. There are well over 700 exercises of varying level leading the reader from the basics to the most advanced levels and frontiers of research. The book can be used either for independent study or for a year-long graduate level course. In fact it has its origin in a year-long graduate course taught by the author in Oxford in 2004-5 and various parts of it in other institutions later on. A good number of distinguished researchers and faculty in mathematics worldwide have started their research career from the course that formed the basis for this book.

In 1996, the Argentine government authorized the use of genetically modified (GM), herbicide-resistance soybean seeds. By the mid-2000s, GM soybeans were cultivated on more than half of the arable land in Argentina and represented one-fourth of the country's exports. While this agricultural boom has benefitted agribusiness companies and fed tax revenues, it also has a dark side: it has accelerated the deforestation of native forests, prompted the eviction of indigenous and peasant families, and spurred episodes of contamination. In Soybeans and Power, Pablo Lapegna investigates the ways in which rural populations have coped with GM soybean expansion in Argentina. Based on over a decade of ethnographic research, Lapegna reveals that many communities initially resisted, yet ultimately adapted to the new agricultural technologies forced upon them by public officials. However, rather than painting the decline of the protests in an exclusively negative light, Lapegna argues that the farmers played an active role in their own demobilization, switching to tactics of negotiation and accommodation in order to maneuver the situation to their advantage. Lapegna offers a rare, on the ground glimpse into the life cycle of a social movement, from mobilization and protest to demobilization and resigned acceptance. Through the case study of Argentina, a major player in the use and export of GM crops, Soybeans and Power gives voice to the communities most adversely affected by GM technology, as well as the strategies that they have enacted in order to survive.

The field of quantum chemistry has grown so immensely that the importance of some of the earliest work and the earliest pioneers of quantum chemistry is unfamiliar to many of today's youngest scientists in the field. Thus, this book is an attempt to preserve some of the very valuable, early history of quantum chemistry, providing the reader with not only a perspective of the science, but a perspective of the early pioneers themselves, some of whom were quite interesting characters. The symposium on which this book is based came about because one of the co-editors (ETS) came to a conviction that the contributions such as those by George Wheland to quantum chemistry and Otto Schmidt to free electron theory should be better appreciated and known. He organized a symposium in which quantum chemistry pioneers, both those celebrated by everyone and those seemingly overlooked by posterity, would be recognized. While this volume is certainly not a history of quantum chemistry, it does cover many highlights over a period of about sixty years. This volume consists of chapters based upon ten of the presentations at the symposium "Pioneers of Quantum Chemistry" held March 28, 2011, at the 241st ACS National Meeting in Anaheim, CA.

Ancient Greek Philosophy routinely relied upon concepts of number to explain the tangible order of the universe. Plotinus' contribution to this tradition, however, has been often omitted, if not ignored. The main reason for this, at first glance, is the Plotinus does not treat the subject of number in the Enneads as pervasively as the Neopythagoreans or even his own successors Lamblichus, Syrianus, and Proclus. Nevertheless, a close examination of the Enneads reveals that Plotinus systematically discusses number in relation to each of his underlying principles of existence--the One, Intellect, and Soul. Plotinus on Number offers the first comprehensive analysis of Plotinus' concept of number, beginning with its origins in Plato and the Neopythagoreans and ending with its influence on Porphyry's arrangement of the Enneads. It's main argument is that Plotinus adapts Plato's and the Neopythagoreans' cosmology to place number in the foundation of the intelligible realm and in the construction of the universe. Through Plotinus' defense of Plato's Ideal Numbers from Aristotle's criticism, Svetla Slaveva-Griffin reveals the founder of Neoplatonism as the first post-Platonic philosopher who purposefully and systematically develops what we may call a theory of number, distinguishing between number in the intelligible realm and number in the quantitative, mathematical realm. Finally, the book draws attention to Plotinus' concept as a necesscary and fundamental linke between Platonic and late Neoplatonic schools of philosophy.

Everyone should read it' PHILIPPA PERRY Why have we lost our ability to focus? What are the causes? And, most importantly, how do we get it back? For Stolen Focus, internationally bestselling author Johann Hari went on a three-year journey to uncover the reasons behind our shortening attention spans. He interviewed the leading experts in the world on attention, and learned that everything we think about this subject is wrong. We think our inability to focus is a personal failing - a flaw in each one of us. It is not. This has been done to all of us by powerful external forces. Our focus has been stolen. Johann discovered there are twelve deep causes of this crisis, all of which have robbed some of our attention. He shows us how in a thrilling journey that ranges from Silicon Valley dissidents, to a favela in Rio where attention vanished, to an office in New Zealand that found a remarkable way to restore our attention. Crucially, he learned how - as individuals, and as a society - we can get our focus back, if we are determined to fight for it.

This book offers a broad discussion of the concepts required to understand the thermodynamic stability of molecules and bonds and a description of the most important condensed-phase techniques that have been used to obtain that information. Above all, this book attempts to provide useful guidelines on how to choose the "best" data and how to use it to understand chemistry. Although the book assumes some basic knowledge on physical-chemistry, it has been written in a "textbook" style and most topics are addressed in a way that is accessible to advanced undergraduate students. Many examples are given throughout the text, involving a variety of molecules.
This text will provide a good starting point for those who wish to initiate in the field or simply to understand how to assess, to estimate, and to use thermochemical data. It will therefore appeal to a broad range of practicing chemists and particularly to those interested in energetics-structure-reactivity relationships.

There are many modes of communication that neurons use to transmit information besides what has come to be called neurotransmission. Many of these other types of communication can be classified as neuromodulatory, where instead of conveying excitation or inhibition, the signal from one neuron changes the properties of other neurons or synapses. This form of neuronal communication is often overlooked by systems physiologists, but it is extremely prevalent in the nervous system and needs to be included in any description of how the nervous system processes information. This book provides the foundations for understanding the cellular and molecular basis for neuromodulatory effects. It illustrates some key examples of the roles played by neuromodulation in sensory processing, neuromuscular transmission, generation of motor behaviours, and learning. Finally, the book seeks to point out areas that are likely to be of importance in the future study of information processing by the nervous system. For neurobiology students and researchers, the book summarizes a vast amount of research, and puts it into the context of how these cellular mechanisms are used in systems of neurons. By spanning the levels of analysis from sub-cellular mechanisms through cellular properties and neuronal systems to behaviour, the book provides a framework for understanding this currently exploding field of research. It is accessible to anyone with a basic understanding of neurobiology, but is in depth enough to satisfy readers who are very familiar with the field.

This volume presents reviews of topical areas in structural determination and structural chemistry, edited from the Proceedings of the 8th Symposium on Organic Crystal Chemistry, held at Poznan-Rydzyna, Poland in 1992. In this volume the definition of organic crystallography is interpreted widely to include factors influencing conformation, packing arrangements, and intermolecular bonding, as well as the determination of the positions and motions of the constituent atoms in molecular structures. An opening chapter introduces the edited proceedings which cover some of the most active areas in the structural determination and structural chemistry of small organic molecules in the crystalline state. The final chapter examines the current concerns of the adherents of organic crystallography and the future role and status of organic crystallography in structural science. The volume is divided into four sections: collection and treatment of diffraction data; crystalline-state reactions; structure correlation and structure-activity relations; and conformation, packing, and bonding in molecular crystals.

This book is a history of the development of mathematical astronomy in China, from the late third century BCE, to the early 3rd century CE - a period often referred to as 'early imperial China'. It narrates the changes in ways of understanding the movements of the heavens and the heavenly bodies that took place during those four and a half centuries, and tells the stories of the institutions and individuals involved in those changes. It gives clear explanations of technical practice in observation, instrumentation, and calculation, and the steady accumulation of data over many years - but it centres on the activity of the individual human beings who observed the heavens, recorded what they saw, and made calculations to analyse and eventually make predictions about the motions of the celestial bodies. It is these individuals, their observations, their calculations, and the words they left to us that provide the narrative thread that runs through this work. Throughout the book, the author gives clear translations of original material that allow the reader direct access to what the people in this book said about themselves and what they tried to do.
