Download or read book Perspectives in Amino Acid and Protein Geochemistry written by Glenn A. Goodfriend and published by Oxford University Press, USA. This book was released on 2000 with total page 392 pages. Available in PDF, EPUB and Kindle. Book excerpt: Amino Acids are not only the essential constituents of all living organisms, they also provide vital clues about life in the past. This book of contributed papers updates the science of amino acid geochemistry and replaces a classic but now outdated work, The Biogeochemistry of Amino Acids (out of print). The new book will have a wider focus than its predecessor, covering preservation of ancient proteins and amino acids, diagenesis of proteins and amino acids through geologic time and on short time scales (relevant to the preservation of museum materials), stable isotope geochemistry of proteins and amino acids, amino acid racemization, the origin of life, the stability of amino acids at hgh temperatures and pressures, and extraterrestrial amino acids. The primary audience for this book will be academics and graduate students in geochemistry, organic chemistry, archaeology, geochronology, and stratigraphy, although it will also be of interest to workers in forensic science.

Available in PDF, EPUB and Kindle. Book excerpt: This Ph. D. dissertation integrates stable isotope and trace element geochemistry in modern and fossil gastropod shells to study low-latitude marine paleoenvironments. First, stable isotopes (delta18O and delta13C) and Sr/Ca ratios are used to examine low-latitude temperature and salinity variations recorded in Plio-Pleistocene (3.5-1.6 Ma) fossils from western Florida during periods of high-latitude warming and "global" cooling. The middle Pliocene Pinecrest Beds (Units 7 and 4) and the overlaying Plio-Pleistocene Caloosahatchee Formation generate significantly different delta18O-derived paleotemperatures but identical Sr/Ca ratios. High delta18O values, together with low delta13C values and brackish fauna, indicate that Unit 4 was deposited in a lagoonal environment similar to modern Florida Bay. In contrast, relatively low delta18O and high delta13C values in Unit 7 and Caloosahatchee Formation represent deposition in an open-marine environment. The observed Unit 7 and Caloosahatchee paleotemperatures are inconsistent with middle Pliocene warming event, but consistent with the Plio-Pleistocene cooling trend. To quantify modern upwelling and freshening signals and contrast these signals between the tropical eastern Pacific (TEP) and southwestern Caribbean (SWC), methodologies are developed for reconstructing seasonal upwelling and freshening patterns from modern tropical gastropod shells from Panama using: 1) paired oxygen and carbon isotopic profiles and delta18O-delta13C (delta-delta) correlations, and 2) deviation from baseline delta18O values that represent conditions free of seasonal upwelling or freshening influences. Shell delta18O values normalized to the baseline faithfully record modern conditions of little or no upwelling in SWC and Gulf of Chiriqui, and strong upwelling in the Gulf of Panama, as well as strong freshwater input in most areas. The baseline and delta-delta methods are applied to identify and quantify changes in upwelling and freshening in the Neogene TEP and SWC seawaters associated with the final closure of Central American Isthmus. The records reveal significant upwelling in late Miocene SWC and mid Pliocene TEP waters, strong freshening in SWC waters from 5.7-2.2 Ma, and minimal seasonal upwelling and/or freshening variations in Plio-Pleistocene SWC waters. The reconstructed paleotemperatures agree with the global cooling trend through the late Miocene, but lack evidence for middle Pliocene warming or late Neogene global cooling.

Download or read book Drugs During Pregnancy and Lactation written by H. Garbis and published by Elsevier Science. This book was released on 2001-12-21 with total page 1300 pages. Available in PDF, EPUB and Kindle. Book excerpt: The care of pregnant women presents one of the paradoxes of modern medicine. Women usually require little medical intervention during an (uneventful) pregnancy. Conversely, those at high risk of damage to their own health or that of their unborn require the help of appropriate medicinal technology, including drugs. Accordingly, there are two classes of pregnant women, the larger group requires support but not much intervention, while the other needs the full range of diagnostic and therapeutic measures applied in any other branch of medicine. This book presents the current state of knowledge about drugs in pregnancy. In each chapter information is presented separately for two different aspects of the problem seeking a drug appropriate for prescription during pregnancy, and assessing the risk of a drug when exposure has already taken place. Practising clinicians who prescribe medicinal products to women who are, or who may become, pregnant, will find this volume an invaluable reference.
Download or read book Biochar for Environmental Management written by Johannes Lehmann and published by Routledge. This book was released on 2012-05-16 with total page 449 pages. Available in PDF, EPUB and Kindle. Book excerpt: Biochar is the carbon-rich product when biomass (such as wood, manure or crop residues) is heated in a closed container with little or no available air. It can be used to improve agriculture and the environment in several ways, and its stability in soil and superior nutrient-retention properties make it an ideal soil amendment to increase crop yields. In addition to this, biochar sequestration, in combination with sustainable biomass production, can be carbon-negative and therefore used to actively remove carbon dioxide from the atmosphere, with major implications for mitigation of climate change. Biochar production can also be combined with bioenergy production through the use of the gases that are given off in the pyrolysis process. This book is the first to synthesize the expanding research literature on this topic. The book's interdisciplinary approach, which covers engineering, environmental sciences, agricultural sciences, economics and policy, is a vital tool at this stage of biochar technology development. This comprehensive overview of current knowledge will be of interest to advanced students, researchers and professionals in a wide range of disciplines.

Download or read book Mangrove Ecosystems A Global Biogeographic Perspective written by Victor H. Rivera-Monroy and published by Springer. This book was released on 2017-11-03 with total page 407 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents a comprehensive overview and analysis of mangrove ecological processes, structure, and function at the local, biogeographic, and global scales and how these properties interact to provide key ecosystem services to society. The analysis is based on an international collaborative effort that focuses on regions and countries holding the largest mangrove resources and encompasses the major biogeographic and socio-economic settings of mangrove distribution. Given the economic and ecological importance of mangrove wetlands at the global scale, the chapters aim to integrate ecological and socio-economic perspectives on mangrove function and management using a system-level hierarchical analysis framework. The book explores the nexus between mangrove ecology and the capacity for ecosystem services, with an emphasis on thresholds, multiple stressors, and local conditions that determine this capacity. The interdisciplinary approach and illustrative study cases included in the book will provide valuable resources in data, information, and knowledge about the current status of one of the most productive coastal ecosystem in the world.
