Book Synopsis Methods of Seawater Analysis by : Klaus Grasshoff
Download or read book Methods of Seawater Analysis written by Klaus Grasshoff and published by John Wiley & Sons. This book was released on 2009-07-30 with total page 632 pages. Available in PDF, EPUB and Kindle. Book excerpt: Since the book first appeared in 1976, Methods of Seawater Analysis has found widespread acceptance as a reliable and detailed source of information. Its second extended and revised edition published in 1983 reflected the rapid pace of instrumental and methodological evolution in the preceding years. The development has lost nothing of its momentum, and many methods and procedures still suffering their teething troubles then have now matured into dependable tools for the analyst. This is especially evident for trace and ultra-trace analyses of organic and inorganic seawater constituents which have diversified considerably and now require more space for their description than before. Methods to determine volatile halocarbons, dimethyl sulphide, photosynthetic pigments and natural radioactive tracers have been added as well as applications of X-ray fluorescence spectroscopy and various electrochemical methods for trace metal analysis. Another method not previously described deals with the determination of the partial pressure of carbon dioxide as part of standardised procedures to describe the marine CO2 system.
Book Synopsis Lake Pavin by : Télesphore Sime-Ngando
Download or read book Lake Pavin written by Télesphore Sime-Ngando and published by Springer. This book was released on 2016-10-31 with total page 422 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the first multidisciplinary scientific work on a deep volcanic maar lake in comparison with other similar temperate lakes. The syntheses of the main characteristics of Lake Pavin are, for the first time, set in a firmer footing comparative approach, encompassing regional, national, European and international aquatic science contexts. It is a unique lake because of its permanently anoxic monimolimnion, and furthermore, because of its small surface area, its substantially low human influence, and by the fact that it does not have a river inflow. The book reflects the scientific research done on the general limnology, history, origin, volcanology and geological environment as well as on the geochemistry and biogeochemical cycles. Other chapters focus on the biology and microbial ecology whereas the sedimentology and paleolimnology are also given attention. This volume will be of special interest to researchers and advanced students, primarily in the fields of limnology, biogeochemistry, and aquatic ecology.

Book Synopsis The Environmental Behaviour of Polonium by : International Atomic Energy Agency
Download or read book The Environmental Behaviour of Polonium written by International Atomic Energy Agency and published by . This book was released on 2018-01-31 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: Polonium-210 is an alpha emitting radionuclide with no radioactive progeny and produces only very-low-intensity gamma rays at very low abundance. This means doses largely arise from internal exposure. In addition to the relatively high ingestion does coefficient of 210Po, radionuclide transfer in the environment results in high activity concentrations in certain foods. This publication focuses on radionuclide transfers in terrestrial, freshwater and marine environments, and provides information on key transfer processes, concepts and models--back cover.

Book Synopsis Evaluation of Cellulose Ethers for Conservation by : Robert L. Feller
Download or read book Evaluation of Cellulose Ethers for Conservation written by Robert L. Feller and published by Getty Publications. This book was released on 1991-03-21 with total page 173 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report is the result of a three-year research program. It describes the chemical character of cellulose ethers as a general class of polymers and establishes an approximate ranking of the relative stability of each generic chemical subclass. Ranking the thermal stability of the polymers with respect to color change and loss in degree of polymerization led to the conclusion that as generic chemical classes, methylcellulose and carboxymethylcellulose appear to be the most stable of the cellulose ethers. Water-soluble ethylhydroxyethylcellulose apparently also possesses good stability. Of questionable long-term stability are hydroxyethylcellulose and hydroxy- propylcellulose. Ethylcellulose and organic-soluble ethylhydroxyethylcellulose proved to be of poor stability, potentially undergoing marked changes in twenty years or less under normal museum conditions. An important additional conclusion reached here, as well as in an earlier investigation, is that considerable variations in stability can occur within a generic chemical class from differences in the basic raw material, a natural product from plants, which is not a uniform, manufactured, chemical substance. Further variations can exist due to different manufacturing processes or commercial sources. Hence, commercial products must be evaluated individually to determine the most stable of a given generic type. Nonetheless, the authors believe the conclusions expressed here to be valid with regard to the relative stability of the generic chemical classes of cellulose ethers.

Book Synopsis Nitrogen Fixation with Non-Legumes by : K.A. Malik
Download or read book Nitrogen Fixation with Non-Legumes written by K.A. Malik and published by Springer. This book was released on 2012-10-13 with total page 362 pages. Available in PDF, EPUB and Kindle. Book excerpt: Diazotrophic bacteria convert atmospheric nitrogen to plant-useable form and this input of nitrogen through biological fixation is of great agronomic importance. The contributions presented in this volume relate to free-living nitrogen fixers and the diazotrophs associated with plants. Symbiotic association of Frankia with non-legumes and cyanobacterial associations are also discussed. Research topics covered in this volume include the biochemistry and genetics of diazotrophs, recent developments in improvement of plant-microbe interactions and their molecular basis, the use of molecular probes in taxonomy and ecology of diazotrophs and reports on field applications, agronomic importance and improvement in methodologies for assessing their contribution to plants. This book provides valuable information not only for researchers working in the field of biological nitrogen fixation but also for biochemistry, molecular biologists, microbiologists and agronomists.
