Book Synopsis How Tobacco Smoke Causes Disease by : United States. Public Health Service. Office of the Surgeon General
Download or read book How Tobacco Smoke Causes Disease written by United States. Public Health Service. Office of the Surgeon General and published by . This book was released on 2010 with total page 728 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report considers the biological and behavioral mechanisms that may underlie the pathogenicity of tobacco smoke. Many Surgeon General's reports have considered research findings on mechanisms in assessing the biological plausibility of associations observed in epidemiologic studies. Mechanisms of disease are important because they may provide plausibility, which is one of the guideline criteria for assessing evidence on causation. This report specifically reviews the evidence on the potential mechanisms by which smoking causes diseases and considers whether a mechanism is likely to be operative in the production of human disease by tobacco smoke. This evidence is relevant to understanding how smoking causes disease, to identifying those who may be particularly susceptible, and to assessing the potential risks of tobacco products.

Book Synopsis Plant-derived Natural Products by : Anne E. Osbourn
Download or read book Plant-derived Natural Products written by Anne E. Osbourn and published by Springer Science & Business Media. This book was released on 2009-07-07 with total page 588 pages. Available in PDF, EPUB and Kindle. Book excerpt: Plants produce a huge array of natural products (secondary metabolites). These compounds have important ecological functions, providing protection against attack by herbivores and microbes and serving as attractants for pollinators and seed-dispersing agents. They may also contribute to competition and invasiveness by suppressing the growth of neighboring plant species (a phenomenon known as allelopathy). Humans exploit natural products as sources of drugs, flavoring agents, fragrances and for a wide range of other applications. Rapid progress has been made in recent years in understanding natural product synthesis, regulation and function and the evolution of metabolic diversity. It is timely to bring this information together with contemporary advances in chemistry, plant biology, ecology, agronomy and human health to provide a comprehensive guide to plant-derived natural products. Plant-derived natural products: synthesis, function and application provides an informative and accessible overview of the different facets of the field, ranging from an introduction to the different classes of natural products through developments in natural product chemistry and biology to ecological interactions and the significance of plant-derived natural products for humans. In the final section of the book a series of chapters on new trends covers metabolic engineering, genome-wide approaches, the metabolic consequences of genetic modification, developments in traditional medicines and nutraceuticals, natural products as leads for drug discovery and novel non-food crops.

Book Synopsis Analytical Artifacts by : B.S. Middleditch
Download or read book Analytical Artifacts written by B.S. Middleditch and published by Elsevier. This book was released on 1989-01-01 with total page 1059 pages. Available in PDF, EPUB and Kindle. Book excerpt: This encyclopaedic catalogue of the pitfalls and problems that all analysts encounter in their work is destined to spend more time on the analyst's workbench than on a library shelf. The author has dedicated the book to ``the innumerable scientists who made mistakes, used impure chemicals and solvents, suffered the consequences of unanticipated side-reactions, and were otherwise exposed to mayhem yet were not too embarrassed to publish their findings''. Traditionally, the mass spectroscopist or gas chromatographer learnt his trade by participating in a 4-6 year apprenticeship as graduate student and post-doctoral researcher. Generally, no formal training was provided on the things that go wrong, but this information was accumulated by sharing in the experiences of colleagues. Nowadays, many novice scientists simply purchase a computerized instrument, plug it in, and use it. Much time can be wasted in studying and resolving problems due to artifacts and there is also a strong possibility that artifacts will not be recognized as such. For example, most analysts realize that they should use glass rather than plastic containers; but few of them would anticipate the possibility of plasticizer residues on glassware washed using detergent from a plastic bottle.This book is an easy-to-use compendium of problems encountered when using various commonly used analytical techniques. Emphasis is on impurities, by-products, contaminants and other artifacts. A separate entry is provided for each artifact. For specific chemicals, this entry provides the common name, mass spectrum, gas chromatographic data, CAS name and registry number, synonyms and a narrative discussion. More than 1100 entries are included. Mass spectral data are indexed in a 6-peak index (molecular ion, base peak, second peak, third peak) and there are also formula, author and subject indexes. An extensive bibliography contains complete literature citations.The book is designed to be used. It will not only allow experienced analysts to profit from the mistakes of others, but it will also be invaluable to other scientists who use analytical instruments in their work.

Book Synopsis Good beekeeping practices for sustainable apiculture by : Food and Agriculture Organization of the United Nations
Download or read book Good beekeeping practices for sustainable apiculture written by Food and Agriculture Organization of the United Nations and published by Food & Agriculture Org.. This book was released on 2021-09-21 with total page 262 pages. Available in PDF, EPUB and Kindle. Book excerpt: Bees provide a critical link in the maintenance of ecosystems, pollination. They play a major role in maintaining biodiversity, ensuring the survival of many plants, enhancing forest regeneration, providing sustainability and adaptation to climate change and improving the quality and quantity of agricultural production systems. In fact, close to 75 percent of the world’s crops that produce fruits and seeds for human consumption depend, at least in part, on pollinators for sustained production, yield and quality. Beekeeping, also called apiculture, refers to all activities concerned with the practical management of social bee species. These guidelines aim to provide useful information and suggestions for a sustainable management of bees around the world, which can then be applied to project development and implementation.
Book Synopsis Extraction of Natural Products Using Near-Critical Solvents by : M.B. King
Download or read book Extraction of Natural Products Using Near-Critical Solvents written by M.B. King and published by Springer Science & Business Media. This book was released on 1992-12-31 with total page 342 pages. Available in PDF, EPUB and Kindle. Book excerpt: The aim of this book is to present the current state of the art of extracting natural products with near-critical solvents and to view the possibilities of further extensions of the technique. Relevant background theory is given but does not dominate the book. Carbon dioxide is the near-critical solvent used in most recent applications and inevitably receives prominence. In addition to general descriptions and reviews, the book contains three chapters by indus trial practitioners who describe in detail the operation of their processes and discuss the market for their products. Sections on the design of the pressure vessels and pumps required in these processes and on the acquisition of the data required for design are included. The costing of the processes is also discussed. There is good scope for combining a near-critical extraction step with other process steps in which the properties of near-critical solvents are utilised, for example as a reaction or crystallisation medium and a chapter is devoted to these important aspects. It is hoped that the work will be found to contain a great deal of specific information of use to those already familiar with this field. However the style of presentation and content is such that it will also be useful as an introduction. In particular it will be helpful to those wondering if this form of separation method has anything to offer for them, whether they are engineers, chemists or managers in industry, or in academic or research institutions.
Book Synopsis Forensic Toxicology by : John S. Oliver
Download or read book Forensic Toxicology written by John S. Oliver and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 295 pages. Available in PDF, EPUB and Kindle. Book excerpt: Forensic toxicology has progressed rapidly and diversified greatly in recent years. The members of the International Association of Forensic Toxicologists provide a valuable service through the association's bulletin. In its pages members hear of new poisons as they are encountered and the analytical techniques used to deal with them. There is a wealth of information in the form of case reports which is used to assist with the interpretation of the results. Each year the members have the opportunity of meeting in Europe. In 1979 the chosen venue was the University of Glasgow and the meeting was hosted by the Department of Forensic Medicine and Science. The department was established by Royal Charter in 1839 within a few years of the beginning of the modern approach to toxicology. In those early years the function of the department was to teach forensic medicine and toxicology. Today the department has become a recognised centre for the teaching of forensic medicine. The toxicology section has expanded greatly to provide the best forensic and environmental toxicology in Scotland. Inorganic analytical facilities are available for the investigation of metallic poisons by atomic absorption spectrometry, neutron activation analysis, X-ray fluorescence and anodic stripping voltametry. Organic analytical toxicology is pursued using gas chromatography, high performance liquid chromatography, immunoassays, and gas chromatography mass spectrometry. Apart from the normal research and routine investigations of a toxicological laboratory the department specialises in the investigation of fire related deaths, solvent abuse (glue sniffing) and trace element studies in human subjects.
Book Synopsis Techniques in Pheromone Research by : Hans E. Hummel
Download or read book Techniques in Pheromone Research written by Hans E. Hummel and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 470 pages. Available in PDF, EPUB and Kindle. Book excerpt: Insects as a group occupy a middle ground in the biosphere between bacteria and viruses at one extreme, amphibians and mammals at the other. The size and general nature of insects present special problems to the student of entomology. For example, many commercially available instruments are geared to measure in grams, while the forces commonly encountered in studying insects are in the milligram range. Therefore, techniques developed in the study of insects or in those fields concerned with the control of insect pests are often unique. Methods for measuring things are common to all sciences. Advances sometimes depend more on how something was done than on what was measured; indeed a given field often progresses from one technique to another as new methods are discovered, developed, and modified. Just as often, some of these techniques find their way into the classroom when the problems involved have been suffi ciently ironed out to permit students to master the manipulations in a few lab oratory periods. Many specialized techniques are confined to one specific research laboratory. Although methods may be considered commonplace where they are used, in another context even the simplest procedures may save considerable time. It is the purpose of this series (1) to report new developments in methodology, (2) to reveal sources of groups who have dealt with and solved particular entomo logical problems, and (3) to describe experiments which may be applicable for use in biology laboratory co~rses.
