Dr. Ruth L. Miller interprets a few essential essays by Ralph Waldo Emerson that tell us how the world always responds to our thoughts, words, and actions, and what we can do to ensure that our life is truly joy-filled in all aspects. In clear, simple language, she gives us a direct sense of what Emerson felt, saw, and struggled to share with his fellow human beings. Emerson transcended the limitations of his day. Using common sense, a love of nature, and his own particular genius, he expressed a higher truth about who we are and how the world gives us exactly what we demand from it. Yet, perhaps because he was so popular, and because so much of what was popularized focused on the need to transcend materialism and reconnect with Nature, some of his core ideas were lost to later generations. They were there, buried in the long sentences and extended paragraphs of his often-overlooked essays—but were discovered only by the few who were willing to take the time and seek them out. These few became great teachers in their own right, the founders and leaders of institutions and movements that have changed history. Natural Abundance makes the hidden treasures of Emerson’s wisdom accessible to 21st century readers. Through it, this great man’s alignment of his heart’s knowing and his intellect’s understanding can lead all of us to a more abundantly fulfilling life, today.

Medicinal Natural Products: A Biosynthetic Approach, Third Edition, provides a comprehensive and balanced introduction to natural products from a biosynthetic perspective, focussing on the metabolic sequences leading to various classes of natural products. The book builds upon fundamental chemical principles and guides the reader through a wealth of diverse natural metabolites with particular emphasis on those used in medicine. There have been rapid advances in biosynthetic understanding over the past decade through enzymology, gene isolation and genetic engineering. Medicinal Natural Products has been extended and fully updated in this new edition to reflect and explain these developments and other advances in the field. It retains the user-friendly style and highly acclaimed features of previous editions: a comprehensive treatment of plant, microbial, and animal natural products in one volume extensive use of chemical schemes with annotated mechanistic explanations cross-referencing to emphasize links and similarities boxed topics giving further details of medicinal materials, covering sources, production methods, use as drugs, semi-synthetic derivatives and synthetic analogues, and modes of action Medicinal Natural Products: A Biosynthetic Approach, Third Edition, is an invaluable textbook for students of pharmacy, pharmacognosy, medicinal chemistry, biochemistry and natural products chemistry.

An updated guide to the most current information available for determining how to use NMR spectroscopy to differentiate chiral compounds Differentiation of Chiral Compounds Using NMR Spectroscopy offers a thoroughly revised second edition to the essential volume that puts the focus on the chiral systems that are commercially available and have been widely vetted for use in NMR spectroscopy. The text covers a broad range of reagents that make it possible to determine the enantiomeric purity and assign the absolute configuration of many classes of compounds. Comprehensive in scope, the text describes the chiral NMR differentiating agents as derivatizing agents, solvating agents, metal-based reagents and liquid crystals and gels, and explains the range and types of compounds for which they can be used for analysis. New to this edition are the most recent findings in the field as well as the development of advanced NMR measurement techniques that allow for the simplification of complex spectra resulting in more readily identified enantiodifferentiation. This important resource: Includes the most recent coverage of a large range of compounds that can be analyzed using chiral NMR reagents Explores the use of chiral NMR reagents and explains their relationship to the stereochemistry of the analyzed molecules Offers the essential information needed to help decide which method is the best NMR method to apply to a class or molecules Contains experimental strategies for using the reagents that are likely to improve the quality of the results Differentiation of Chiral Compounds Using NMR Spectroscopy is a comprehensive guide designed for investigators planning to use NMR spectroscopy to determine enantiomeric purity or assign the absolute configuration of a compound.

This book highlights new and emerging uses of stable isotope analysis in a variety of ecological disciplines. While the use of natural abundance isotopes in ecological research is now relatively standard, new techniques and ways of interpreting patterns are developing rapidly. The second edition of this book provides a thorough, up-to-date examination of these methods of research. As part of the Ecological Methods and Concepts series which provides the latest information on experimental techniques in ecology, this book looks at a wide range of techniques that use natural abundance isotopes to: follow whole ecosystem element cycling understand processes of soil organic matter formation follow the movement of water in whole watersheds understand the effects of pollution in both terrestrial and aquatic environments study extreme systems such as hydrothermal vents follow migrating organisms In each case, the book explains the background to the methodology, looks at the underlying principles and assumptions, and outlines the potential limitations and pitfalls. Stable Isotopes in Ecology and Environmental Science is an ideal resource for both ecologists who are new to isotopic analysis, and more experienced isotope ecologists interested in innovative techniques and pioneering new uses.

Since the introduction of FT-NMR spectroscopy around five decades ago, NMR has achieved significant advances in hardware and methodologies, accompanied with the enhancement of spectral resolution and signal sensitivity. Rapid developments in the polymers field mean that accurate and quantitative characterization of polymer structures and dynamics is the keystone for precisely regulating and controlling the physical and chemical properties of the polymer. This book specifically focuses on NMR investigation of complex polymers for the polymer community as well as NMR spectroscopists, and will push the development of both fields. It covers the latest advances, for example high field DNP and ultrafast MAS methodologies, and show how these novel NMR methods characterize various synthetic and natural polymers.
