The book provides beneficial text for an academic and professional audience and serves as a source of knowledge for anyone who is interested in the fascinating subject of alkaloids. Each chapter features an abstract. Appendices are included, as are a listing of alkaloids, plants containing alkaloids and some basic protocols of alkaloid analysis.

  • Oxidative Stress and Neurodegenerative Disorders

    • 1st Edition
    • G. Ali Qureshi + 1 more
    • English
    Oxidative stress is the result of an imbalance in pro-oxidant/antioxid... homeostasis that leads to the generation of toxic reactive oxygen species. Brain cells are continuously exposed to reactive oxygen species generated by oxidative metabolism, and in certain pathological conditions defense mechanisms against oxygen radicals may be weakened and/or overwhelmed. DNA is a potential target for oxidative damage, and genomic damage can contribute to neuropathogenesis. It is important therefore to identify tools for the quantitative analysis of DNA damage in models on neurological disorders. This book presents detailed information on various neurodegenerative disorders and their connection with oxidative stress. This information will provide clinicians with directions to treat these disorders with appropriate therapy and is also of vital importance for the drug industries for the design of new drugs for treatment of degenerative disorders.

  • The Nutritional Biochemistry of Chromium(III)

    • 1st Edition
    • John Vincent
    • English
    Chromium nutritional supplements are the second best selling mineral supplements after calcium as chromium is found in pills, sports drinks, chewing gums, smoothies, and numerous other products. Chromium has been promoted to promote weight loss and muscle development and most recently to be available to treat the symptoms of type 2 diabetes and related conditions. The aim of The Nutritional Biochemistry of Chromium(III) is to examine the four most controversial areas of chromium nutrition and biochemistry: - is chromium an essential element for humans and are chromium nutritional supplements of value? - what biochemical role, if any, does chromium play in the body - can large doses of chromium(III) be used to treat symptoms of type 2 diabetes, cardiovascular disease, and related medical conditions - is the use of chromium(III) supplements a health concern. Scientific experts, who are recognized leaders in the field, weigh in with their opinions on both sides of these issues in this book.A background review of the field from 1955-1995 by Vincent opens the book and concludes with a summary by Dr. Forrest Nielsen, Center Director of the USDA's Grand Forks Human Nutrition Research Center concludes the book.

  • Systems Biology

    Philosophical Foundations
    • 1st Edition
    • Fred Boogerd + 3 more
    • English
    Systems biology is a vigorous and expanding discipline, in many ways a successor to genomics and perhaps unprecedented in its combination of biology with a great many other sciences, from physics to ecology, from mathematics to medicine, and from philosophy to chemistry. Studying the philosophical foundations of systems biology may resolve a longer standing issue, i.e., the extent to which Biology is entitled to its own scientific foundations rather than being dominated by existing philosophies.

  • Juneau Icefield Research Project (1949-1958)

    • 1st Edition
    • Volume 8
    • Cal Heusser
    • English
    The Juneau Icefield Research Project (JIRP) was formed to find a prototype area to study Alaska's coastal glaciers and trends in climatic change. For the past 57 years JIRP has conducted a systematic study of key receding and advancing glaciers, including Lemon Creek and Taku Glaciers. From this study, a model has been developed to study the mass balance of these glaciers and their relation to general atmospheric circulation. Taku's mass balance was expected to provide a meaningful assessment of flakier climate relations and environmental trends, specifically the increase in atmospheric trace element pollution and global warming.Juneau Icefield Research Project (1949-1958) is represented by 15 chapters, organized in four parts: Background of the Project, Early Years of the Project (1949-1952, Later Years of the Project (1953-1958), and Summation and Epilogue. After describing the Project's background, Chapters 3 through 12 cover year-by-year activities, personnel, logistics, and research of the Taku and Lemon Creek Glaciers. These chapters included day-to-day journal entries that represent a record of the informal itineraries covering the course of the study. Chapters 13 and 14 summarize glaciological findings on Taku Glacier and the status of hydrological budgets on Lemon Creek Glacier through the International Geophysical year (1957-19658). The final chapter of the text is an overview of paleoecological work by the Project in North Pacific America brought into the context of modern research with the recognition of glacier-climate cycles.

  • High Pressure Rheology for Quantitative Elastohydrodynamics

    • 1st Edition
    • Scott S. Bair
    • English
    Computational elastohydrodynamics, a part of tribology, has existed happily enough for about fifty years without the use of accurate models for the rheology of the liquids used as lubricants. For low molecular weight liquids, such as low viscosity mineral oils, it has been possible to calculate, with precision, the film thickness in a concentrated contact provided that the pressure and temperature are relatively low, even when the pressure variation of viscosity is not accurately modelled in detail. Other successes have been more qualitative in nature, using effective properties which come from the fitting of parameters used in calculations to experimental measurements of the contact behaviour, friction or film thickness. High Pressure Rheology for Quantitative Elastohydrodynamics is intended to provide a sufficiently accurate framework for the rheology of liquids at elevated pressure that it may be possible for computational elastohydrodynamics to discover the relationships between the behaviour of a lubricated concentrated contact and the measurable properties of the liquid lubricant. The required high-pressure measurement techniques are revealed in detail and data are presented for chemically well-defined liquids that may be used as quantitative reference materials.

  • UV-visible Spectrophotometry of Water and Wastewater

    • 1st Edition
    • Volume 27
    • Olivier Thomas + 1 more
    • English
    UV-Visible Spectrophotometry of Water and Wastewater is the first book dedicated to the use of UV spectrophotometry for water and wastewater quality monitoring. Using practical examples the reader is shown how this technique can be a source of new methods of characterization and measurement. Easy and fast to run, this simple and robust analytical technique must be considered as one of the best ways to obtain a quantitative estimation of specific or aggregate parameters (eg. Nitrate, TOC), and simultaneously qualitative information on the global composition of water and its variation.

  • Computational Methods for Modeling of Nonlinear Systems by Anatoli Torokhti and Phil Howlett

    • 1st Edition
    • Volume 212
    • Anatoli Torokhti + 1 more
    • English
    In this book, we study theoretical and practical aspects of computing methods for mathematical modelling of nonlinear systems. A number of computing techniques are considered, such as methods of operator approximation with any given accuracy; operator interpolation techniques including a non-Lagrange interpolation; methods of system representation subject to constraints associated with concepts of causality, memory and stationarity; methods of system representation with an accuracy that is the best within a given class of models; methods of covariance matrix estimation; methods for low-rank matrix approximations; hybrid methods based on a combination of iterative procedures and best operator approximation; and methods for information compression and filtering under condition that a filter model should satisfy restrictions associated with causality and different types of memory. As a result, the book represents a blend of new methods in general computational analysis, and specific, but also generic, techniques for study of systems theory ant its particular branches, such as optimal filtering and information compression.
