Download or read book StarBriefs 2001 written by and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 805 pages. Available in PDF, EPUB and Kindle. Book excerpt: This compilation probably looks like one of the craziest things a human being could spend his or her time on. Yet nobody would wonder at someone taking a short walk every day - after twenty five years that person would have covered a surprisingly long distance. This is exactly the story behind this list, which appeared first as a few pages within the directory StarGuides (or whatever name it had at that time) and as a distinct sister publication since 1990. The idea behind this dictionary is to offer astronomers and related space scientists practical assistance in decoding the numerous abbreviations, acronyms, contractions and symbols which they might encounter in all aspects of the vast range of their professional activities, including traveling. Perhaps it is a bit paradoxical, but if scientists quickly grasp the meaning of an acronym solely in their own specific discipline, they will probably encounter more difficulties when dealing with adjacent fields. It is for this purpose that this dictionary might be most often used. Scientists might also refer to this compilation in order to avoid identifying a project by an acronym which already has too many meanings or confused definitions.
Download or read book Compendium of Terminology and Nomenclature of Properties in Clinical Laboratory Sciences written by Georges Férard and published by Royal Society of Chemistry. This book was released on 2016-11-11 with total page 213 pages. Available in PDF, EPUB and Kindle. Book excerpt: There has been significant expansion and development in clinical laboratory sciences and, in particular, metrological concepts, definitions and terms since the previous edition of this book was published in 1995. It is of prime importance to standardize laboratory reports for reliable exchange of patient examination data without loss of meaning or accuracy. New disciplines have appeared and the interrelationships between different disciplines within clinical laboratory sciences demand a common structure and language for data exchange, in the laboratory and with the clinicians, necessitating additional coverage in this book. These new sections will be based upon recommendations published by various national, regional, and international bodies especially IUPAC and IFCC. This book groups and updates the recommendations and will be appropriate for laboratory scientists, medical professionals and students in this area.

Download or read book Molten Salts and Ionic Liquids written by Marcelle Gaune-Escard and published by John Wiley & Sons. This book was released on 2012-07-06 with total page 466 pages. Available in PDF, EPUB and Kindle. Book excerpt: For many years, the related fields of molten salts and ionic liquids have drifted apart, to their mutual detriment. Both molten salts and ionic liquids are liquid salts containing only ions - all that is different is the temperature! Both fields involve the study of Coulombic fluids for academic and industrial purposes; both employ the same principles; both require skilled practitioners; both speak the same language; all then that is truly different is their semantics, and how superficial is that? The editors of this book, recognising that there was so much knowledge, both empirical and theoretical, which can be passed from the molten salt community to the ionic liquid community, and vice versa, organised a landmark meeting in Tunisia, designed to bridge the gap and heal the rift. Leaders from both communities met for a week for a mutual exchange, with a high tutorial content intermixed with cutting edge findings. This volume is a condensate of the principal offerings of that week, and emphasises the success which was achieved. Indeed, four future biannual meetings, under the title of “EUCHEM Conferences on Molten Salts and Ionic Liquids”, have now been planned as a direct result of this meeting of minds. Topics discussed in this volume include structure, dynamics, electrochemistry, interfacial and thermodynamic properties, spectroscopy, synthesis, and theoretical studies. Experimental and theoretical methods for investigating these data are elaborated, as are techniques for data collection and analysis. This book represents the first serious discussion on the transfer of these methods and techniques between the differing temperature regimes, and is a major contribution to the future of both fields.
Download or read book Isotope Dilution Mass Spectrometry written by Jose Alonso and published by Royal Society of Chemistry. This book was released on 2019-03-22 with total page 473 pages. Available in PDF, EPUB and Kindle. Book excerpt: Isotope Dilution Mass Spectrometry (IDMS) has become an essential tool in research laboratories and is increasingly used in routine analysis labs (including environmental, food safety and clinical applications). This is the first textbook to present a comprehensive and instructive view of the theory and applications of this growing technique. The main objective of this book is to cover the theory and applications of Isotope Dilution in Analytical Chemistry. The scope is comprehensive to include elemental analysis, speciation analysis, organic analysis and biochemical and clinical analysis together with applications in metabolism studies and traceability of goods. Until now there have been no books published with the same general scope (only book chapters on particular applications). This is a textbook focused at post-graduate level covering the basic knowledge required for doctoral studies in this field. Isotope Dilution Mass Spectrometry will also outline practical applications of interest for routine testing laboratories where isotope dilution procedures are implemented or can be implemented in the future. This unique book covers all the theoretical and practical aspects of Isotope Dilution Mass Spectrometry (IDMS). Due to the increasing application of IDMS in many research laboratories and the increasing implementation of IDMS methodologies in routine testing laboratories, scientists in industry and working in or affiliated to this area will this an invaluable source of information. Concerning the theoretical aspects, the authors present a uniform theoretical background which grows from previous developments in Organic, Speciation and Elemental analysis both in their own laboratory and in other laboratories around the world. This general approach will be simpler and will also include new emerging fields such as quantitative proteomics and metabolism studies.
