Abstract

Speciation analysis is a field of trace element analytical chemistry that deals with detection, identification and determination of individual chemical forms of metals and metalloids. There has been increased awareness of the importance of elemental speciation over the last 20 years and this has lead to growing demand for analytical techniques capable of providing species-specific information. Hyphenated Techniques in Speciation Analysis offers a brief but comprehensive overview of hyphenated techniques and their various applications for the determination of chemical forms of trace elements. I

Abstract

This international collection of chapters comprehensively covers different aspects of procedures for speciation analysis at all levels starting from sample collection and storage, through sample preparation approaches to render the species chromatographable, principles of separation techniques used in speciation analysis, to the element specific detection. International renowned editors and contributors Includes coverage of electrochemical methods, biosensors for metal ions, radioisotope techniques and direct solid speciation techniques Provides information on quality assurance and risk assessment, and speciation-relevant legislation Each chapter is a stand-alone reference covering a given facet of elemental speciation analysis written by an expert in a given field with the volume as a whole providing an excellent introductory text and reference handbook. Written by an internationally recognized group of editors and contributors, Handbook of Elemental Speciation, Volume 2 provides a comprehensive, cross-disciplinary presentation of the analytical techniques involved in speciation. Comprehensive coverage of key elements and compounds in situ Addresses the analysis and impact of these elements and compounds, e.g. arsenic, lead, copper, iron, halogens, etc.,_ in food, the environment, clinical and occupational health Detailed methodology and data are reported, as well as regulatory limits Includes general introduction on the impact in these key areas

Abstract

The population genetics and speciation of fungi is a rapidly developing field, heavily dependent upon the use of molecular markers. No basic text exists which describes the methods employed or the findings obtained from such investigations. This book is intended to provide such an account. It describes the methodologies employed and, for the benefit of the non-mycological reader, a brief introduction to basic fungal biology. Recent findings relating to processes in fungal populations - mutation, migration, recombination, heterokaryosis, hybridization, polyploidy, and the operation of selective forces are combined with traditional fungal biology. Finally the taxonomic problems raised by fungal species are discussed, together with the processes of speciation.

Abstract

This book should be of value to anyone interested in bird evolution and taxonomy, biogeography, distributional history, dispersal and migration patterns. It provides an up-to-date synthesis of current knowledge on species formation, and the factors influencing current distribution patterns. It draws heavily on new information on Earth history, including past glacial and other climatic changes, on new developments in molecular biology and palaeontology, and on recent studies of bird distribution and migration patterns, to produce a coherent account of the factors that have influenced bird speci

Abstract

Historienne et philosophe des sciences, professeur au MIT, Evelyn Fox Keller présente ici une analyse du progrès de la génétique et de la biologie moléculaire au XXe siècle.Sans s'en tenir à une histoire de la biologie qui passe du gène, dont le mot est forgé en 1909, au génome, avec l'achèvement, au moins partiel, du projet " Génome humain " en février 2001, Le Siècle du gène attire notre attention sur les façons surprenantes dont cette progression démolit les idées courantes, voire caricaturales, sur le gène et sur le programme génétique que la plupart d'entre nous partagent encore.Evelyn Fox Keller montre en effet que les succès mêmes qui ont emporté notre imagination ont aussi radicalement miné le caractère central du gène en tant que concept explicatif de l'hérédité et du développement, même s'il continue d'être utilisé et n'est pas près d'être abandonné. Avec le séquençage complet du génome humain, les biologistes en sont venus à se rendre compte qu'ils n'avaient pas atteint la fin de la biologie, mais qu'ils étaient au commencement d'une nouvelle époque.Non seulement ils n'avaient pas trouvé le " secret de la vie ", mais cet aboutissement révélait plus encore la complexité de l'ordre du vivant et les limites de la vision qui fut à l'origine de la génétique. Il restait cette fois à comprendre la manière dont les composants élémentaires s'assemblent et " fonctionnent " ensemble, ce qui rend leur assemblage robuste, fiable et apte à évoluer. Dans un petit ouvrage clair, précis et au ton alerte, en dépit de la difficulté du sujet, Evelyn Fox Keller réussit à introduire le non-spécialiste à des questions qui engagent la portée des applications de la science et les enjeux actuels de la recherche.
