Download or read book The Secrets of a Fifty Year Romantic Expedition written by Matthew E. McLaren PhD and published by iUniverse. This book was released on 2015-06-04 with total page 127 pages. Available in PDF, EPUB and Kindle. Book excerpt: Do you remember the first day I saw you? The first date we had? The first time I took you into my arms? The vow we made? Do you realize it is fifty years since we said I do? I love you my first lady, my queen. With Jesus as our guiding light we will continue to walk together until death. By the power of prayer I have found you. You are my special treasure. You are a life partner with so much strength and compassion, a partner with such integrity and goodness in your heart; you have guarded the inner circle of our relationship and made it the sacred centre of our life, just for Jesus, you and me. God used a picture in Ezekiel 16 to describe His people and I would like to paraphrase it by saying. When I pass by you again and look upon you, indeed your heart was the heart of love; so I spread my arms and covered you, I went into a covenant with you; a covenant that cannot be broken. The more I know you, the deeper I appreciate and love you. Its like how Id cherish and treasure a rare and priceless work of art.

Download or read book Half a Century of Free Radical Chemistry written by Derek H. R. Barton and published by Cambridge University Press. This book was released on 1993-04-15 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book describes the experience over 25 years of the senior author with the chemistry of organic free radicals. It begins with a mechanistic study of industrial importance on the pyrolysis of chlorinated alkanes. It continues with a theory on the biosynthesis of phenolate derived alkaloids involving phenolate radical coupling. There follows 20 years of practical work to prove the theory correct, especially in the case of morphine alkaloids. The book then describes the work on nitrile photolysis (Barton reaction) which involved the invention of new radical chemistry leading to a simple synthesis of the important hormone, aldosterone. There follows a description of the invention of an important new method for the deoxygenation of biologically important molecules, especially sugars and nucleosides, using radical chemistry applied to thiocarbonyl derivatives. Some years later, in a logical extension to carboxylic acids, another new reaction was invented which provides carbon, nitrogen, oxygen and other radicals under mild conditions. A final chapter summarizes recent applications of thiocarbonyl group derived radical reactions by other authors.

Available in PDF, EPUB and Kindle. Book excerpt: Origin, Scope, and Plan of this Book In July 1962 the fiftieth anniversary of Max von Laue's discovery of the Diffraction of X-rays by crystals is going to be celebrated in Munich by a large international group of crystallographers, physi cists, chemists, spectroscopists, biologists, industrialists, and many others who are employing the methods based on Laue's discovery for their own research. The invitation for this celebration will be issued jointly by the Ludwig Maximilian University of Munich, where the discovery was made, by the Bavarian Academy of Sciences, where it was first made public, and by the International Union of Crystallo graphy, which is the international organization of the National Committees of Crystallography formed in some 30 countries to repre sent and advance the interests of the 3500 research workers in this field. The year 1912 also is the birth year of two branches of the physical sciences which developed promptly from Laue's discovery, namely X-ray Crystal Structure Analysis which is most closely linked to the names ofW. H. (Sir William) Bragg and W. L. (Sir Lawrence) Bragg, and X-ray Spectroscopy which is associated with the names of W. H. Bragg, H. G. J. Moseley, M. de Broglie and Manne Siegbahn. Crystal Structure Analysis began in November 1912 with the first papers ofW. L. Bragg, then still a student in Cambridge, in which, by analysis of the Laue diagrams _of zinc blende, he determined the correct lattice upon which the structure of this crystal is built.

Download or read book Dietary Reference Intakes for Vitamin C Vitamin E Selenium and Carotenoids written by Institute of Medicine and published by National Academies Press. This book was released on 2000-08-27 with total page 530 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume is the newest release in the authoritative series of quantitative estimates of nutrient intakes to be used for planning and assessing diets for healthy people. Dietary Reference Intakes (DRIs) is the newest framework for an expanded approach developed by U.S. and Canadian scientists. This book discusses in detail the role of vitamin C, vitamin E, selenium, and the carotenoids in human physiology and health. For each nutrient the committee presents what is known about how it functions in the human body, which factors may affect how it works, and how the nutrient may be related to chronic disease. Dietary Reference Intakes provides reference intakes, such as Recommended Dietary Allowances (RDAs), for use in planning nutritionally adequate diets for different groups based on age and gender, along with a new reference intake, the Tolerable Upper Intake Level (UL), designed to assist an individual in knowing how much is "too much" of a nutrient.
Download or read book Chemical History written by Gerrylyn K Roberts and published by Royal Society of Chemistry. This book was released on 2007-10-31 with total page 261 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book provides an historical overview of the recent developments in the history of diverse fields within chemistry. It follows on from Recent Developments in the History of Chemistry, a volume published in 1985. Covering chiefly the last 20 years, the primary aim of Chemical History: Reviews of the Recent Literature is to familiarise newcomers to the history of chemistry with some of the more important developments in the field. Starting with a general introduction and look at the early history of chemistry, subsequent chapters go on to investigate the traditional areas of chemistry (physical, organic, inorganic) alongside analytical chemistry, physical organic chemistry, medical chemistry and biochemistry, and instruments and apparatus. Topics such as industrial chemistry and chemistry in national contexts, whilst not featuring as separate chapters, are woven throughout the content. Each chapter is written by experts and is extensively referenced to the international chemical literature. Chemical History: Reviews of the Recent Literature is also ideal for chemists who wish to become familiar with historical aspects of their work. In addition, it will appeal to a wider audience interested in the history of chemistry, as it draws together historical materials that are widely scattered throughout the chemical literature.
Download or read book From Atoms to Molecules written by Colin A. Russell and published by Taylor & Francis. This book was released on 2024-08-01 with total page 331 pages. Available in PDF, EPUB and Kindle. Book excerpt: The focus of this volume by Professor Russell is the history of organic chemistry, which arose improbably out of early speculations about the construction of chemical compounds, and in particular their electrochemical nature. The rise of electrochemistry and the work of Berzelius were critical in this regard, and receive much attention in the first few chapters in this book. Aspects of the contributions of Frankland (fully explored elsewhere) and those of Kekulê and Hofmann are considered, together with the miscellaneous functions of organic synthesis and the origins of conformational analysis. Questions of chemical organisation are germane to the whole sequence of events and are briefly summarized before the whole last hundred years of organic chemistry are placed in historical perspective.
Download or read book Free Radicals in Biology and Environment written by F. Minisci and published by Springer Science & Business Media. This book was released on 2013-04-17 with total page 496 pages. Available in PDF, EPUB and Kindle. Book excerpt: Our understanding of the quantitative aspects of free radical chemistry and the involvement of radicals in such areas as biology, medicine, the environment, etc., has developed spectacularly over recent years, yet the various topics are commonly discussed separately, in specific meetings and specialised publications. Free Radicals in Biology and Environment draws together two important areas of free radical chemistry, using as a bridge the fundamental physical chemistry of free radicals (spectroscopic detection of free radicals, evaluation of absolute rate constants, elucidation of mechanisms of free radical reactions and catalysis, photochemical and radiation processes, etc.). The most relevant topics covered are the EPR detection of radicals in biochemical systems and in pollutant formation and degradation, oxidation processes in biology and in the troposphere, radiation and induced damage, and atmospheric pollutants arising from incomplete combustion. Also covered are the chemistry and biochemistry of nitric oxide and peroxynitrite, the chemistry and biochemistry of DNA radicals, the role of radicals in myeloperoxidase, lignineperoxidase, radicals and cardiovascular injury, radiation and the fragmentation of cells and tissues.

Download or read book Solar Energy Absorbing Substances and Oxidative Stress and Inflammatory Diseases written by C. Thomas Gnewuch and published by Cambridge Scholars Publishing. This book was released on 2017-06-23 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book explores various topics relevant to understanding the complexities of biological effects generated by solar radiation. Solar-energy-absorbing substances are evaluated, including sunscreen agents, and their influence on cancers and diseases. One assumption is the use of sunscreen agents cannot prevent the photoinitiation of biological system malfunction, such as immunosuppression. On the contrary, sunscreens can help enhance the negative solar-energy-induced effects, such as by skin penetration. This collection offers critical appraisals of clinical studies involving vitamins and nonsteroidal anti-inflammatory agents for alleviating, mitigating, or even curing of various inflammatory diseases including cancers.
