    * A large cross-section of organic reactions/mechanisms given with stereochemical implications. * Relationship between conformation and reactivity specially highlighted. * Instrumentation techniques relating to stereochemical investigation discussed in simple language.ABOUT THE BOOK:During recent years, stereochemistry has undergone a phenomenal growth both in theory and practice, with a concomitant increase of interest among the organic chemists, biological chemists, medicinal chemists, and pharmacologists. The present text provides an up-to-date, coherent, and comprehensive account of the subject starting from the fundamentals and leading up to the latest developments as far as practicable. Emphasis has been placed on a symmetry-based approach to molecular chirality, stereochemical terminologies (modern stereochemistry is replete with them), topicity and prostereoisomerism, conformational analysis, dynamic stereochemistry, chiroptical properties, and assignment of absolute configuration to chiral molecules. Dynamic stereochemistry has been discussed with reference to conformation-reactivity correlation, stereoselective synthesis, and pericyclic reactions. A large cross-section of organic reactions with stereochemical implication has been incorporated. Attempts have been made to familiarise the readers with modern instrumental techniques, nuclear magnetic resonance in particular, used for stereochemical investigation. Each chapter is provided with a summary which highlights the main points of the text.

    If you've been searching for a basic text on how the atom works, this is it." --Booklist "A masterpiece."--OmniThe legendary Isaac Asimov starts what is perhaps the most fascinating of all his books with a simple query: how finely can a piece of matter be divided? But like many simple questions, this one leads us on a far-flung quest for a final answer, a search that becomes a series of beautifully structured building blocks of knowledge.It begins with the earliest speculations and investigations by the Greeks and Romans, and then, step by step and century by century, it traces the path of discovery that revealed more and more of the nature of the atom, of light, of gravity, of the electromagnetic force--and even the nature and structure of the universe.Atom also encompasses such phenomena as light and electricity; the protons, neutrons and quarks that are the fundamental units of the universe; hard-to-observe "anti-particles"; and other strange bits of matter that challenge our assumptions about the very nature of space and time.Atom is the only book of its kind, by the renowned author whose genius for bringing clarity and excitement to complex subjects has made him the most celebrated science author of our time.

    While we may take our air for granted, Earth was not always an oxygenated planet. How did it become this way? "Oxygen" is the most current account of the history of atmospheric oxygen on Earth. Donald Canfield--one of the world's leading authorities on geochemistry, earth history, and the early oceans--covers this vast history, emphasizing its relationship to the evolution of life and the evolving chemistry of the Earth. With an accessible and colorful first-person narrative, he draws from a variety of fields, including geology, paleontology, geochemistry, biochemistry, animal physiology, and microbiology, to explain why our oxygenated Earth became the ideal place for life.Describing which processes, both biological and geological, act to control oxygen levels in the atmosphere, Canfield traces the records of oxygen concentrations through time. Readers learn about the great oxidation event, the tipping point 2.3 billion years ago when the oxygen content of the Earth increased dramatically, and Canfield examines how oxygenation created a favorable environment for the evolution of large animals. He guides readers through the various lines of scientific evidence, considers some of the wrong turns and dead ends along the way, and highlights the scientists and researchers who have made key discoveries in the field.Showing how Earth's atmosphere developed over time, "Oxygen" takes readers on a remarkable journey through the history of the oxygenation of our planet.

    An x-ray microscope would do the trick, or since we're dreaming, perhaps an Asimov-style nanosubmarine (unfortunately, neither is currently feasible). Think of the wonders we could witness firsthand: antibodies atta- ing a virus, electrical signals racing down nerve fibers, proteins building new strands of DNA. Many of the questions puzzling the current cadre of sci- tists would be answered at a glance. But the nanoscale world of molecules is separated from our everyday world of experience by a daunting million-fold difference in size, so the world of molecules is completely invisible. I created the illustrations in this book to help bridge this gulf and allow us to see the molecular structure of cells, if not directly, then in an artistic rendition. I have included two types of illustrations with this goal in mind: watercolor paintings which magnify a small portion of a living cell by one million times, showing the arrangement of molecules inside, and comput- generated pictures, which show the atomic details of individual molecules. In this second edition of The Machinery of Life, these illustrations are presented in full color, and they incorporate many of the exciting scientific advances of the 15 years since the first edition.

    Examples of analytical techniques are drawn from such areas as life sciences, clinical chemistry, air and water pollution, and industrial analyses. New to this edition: Excel spreadsheets on CD-ROM * New chapters on good laboratory practice, as well as genomics and proteomics * A more modern flavor.

    Jonas Speller still has a lot to learn when he meets college student Victoria Schone, whose troubled relationship with her parents has her teetering on the verge of suicide. As Jonas struggles to make sense of his feelings for Victoria, he helps her become her own person and stand up to her overpowering mother, while she challenges the budding doctor to become more emotionally forthcoming and involved with her. Years later, a crisis in Victoria’s life reunites doctor and patient, forcing them to confront poignant truths about themselves, their families, and their powerful feelings for each other. Intensive Therapy: A Novel takes readers deep inside the hearts and minds of analyst and patient as they grapple with the limits of doctor-patient propriety. The novel, Deitz’s first, has garnered widespread praise both within the therapy community and the literary world.

    "It would be hard to design a more reliable timekeeper." In Nature's Clocks, Macdougall tells how scientists who were seeking to understand the past arrived at the ingenious techniques they now use to determine the age of objects and organisms. By examining radiocarbon (C-14) dating—the best known of these methods—and several other techniques that geologists use to decode the distant past, Macdougall unwraps the last century's advances, explaining how they reveal the age of our fossil ancestors such as "Lucy," the timing of the dinosaurs' extinction, and the precise ages of tiny mineral grains that date from the beginning of the earth's history. In lively and accessible prose, he describes how the science of geochronology has developed and flourished. Relating these advances through the stories of the scientists themselves—James Hutton, William Smith, Arthur Holmes, Ernest Rutherford, Willard Libby, and Clair Patterson—Macdougall shows how they used ingenuity and inspiration to construct one of modern science's most significant accomplishments: a timescale for the earth's evolution and human prehistory.
