Download or read book Evolution of the First Nervous Systems written by Peter A.V. Anderson and published by Springer. This book was released on 2013-07-18 with total page 424 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book represents the proceedings of a NATO Advanced Research Workshop of the same name, held at St. Andrews University, Scotland in July of 1989. It was the first meeting of its kind and was convened as a forum to review and discuss the phylogeny of some of the cell biological functions that underlie nervous system function, such matters as intercellular communication in diverse, lower organisms, and the electrical excitability of protozoans and cnidarians, to mention but two. The rationale behind such work has not necessarily been to understand how the first nervous systems evolved; many of the animals in question provide excellent opportunities for examining general questions that are unapproachable in the more complex nervous systems of higher animals. Nevertheless, a curiosity about nervous system evolution has invariably pervaded much of the work. The return on this effort has been mixed, depending to a large extent on the usefulness of the preparation under examination. For example, work on cnidarians, to many the keystone phylum in nervous system evolution simply because they possess the "first" nervous systems, lagged behind that carried out on protozoans, because the latter are large, single cells and, thus, far more amenable to microelectrode-based recording techniques. Furthermore, protozoans can be cultured easily and are more amenable to genetic and molecular analyses.

Download or read book Wastewater Treatment with Algae written by Yuk Shan Kwong and published by Springer Science & Business Media. This book was released on 2013-03-09 with total page 265 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book brings together environmental scientists and engineers to discuss the development of new approaches and methodologies which utilize microalgae for biological wastewater treatment. The researchers report their recent findings on microalgal removal of nutrients, heavy metals and other organic pollutants from sewage and industrial effluents. The technologies discussed here include biosorption and bioaccumulation of heavy metals, cell immobilization of algae, and mathematical modelling of metal uptake by cells. This book is unique in that it takes a practical approach to the subject matter and is a useful reference both in and outside of the laboratory.

This book was released on 2012-12-06 with total page 270 pages. Available in PDF, EPUB and Kindle. Book excerpt: The "European Experiment on the Transport and Transformation of Environmentally Relevant Trace Constituents over Europe" (EUROTRAC) was established in 1986 to tackle the scientific problem and combine the expertise, knowledge and resources in Europe, in order to apply them over a large region covering the greater part of the continent. EUROTRAC is a coordinated multidisciplinary scientific research project involving field measurements, laboratory studies, instrument development and development of comprehensive computer models for the simulation of the physical and chemical processes in the lower atmosphere.

Download or read book Transport and Chemical Transformation of Pollutants in the Troposphere written by Peter Borrell and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 446 pages. Available in PDF, EPUB and Kindle. Book excerpt: A major environmental concern is the increasing burden on all scales of photo-oxidants, acidifying substances and potential nutrients in the troposphere. These lead to episodes of summer smog, and appreciable damage to eco-systems both on land and at sea. Underlying the environmental effects is the complex scientific problem of linking the man-made and biological emissions to the myriad chemical reactions that transform the pollutants as they are transported to and deposited in the surroundings and also pristine areas remote from the sources. The project, the scientific results of which are described in this book, was set up to study the problem in an inter-disciplinary way by co-ordinating the work of more than 150 research groups in some 20 countries.

Available in PDF, EPUB and Kindle. Book excerpt: L'enseignement des Sciences expérimentales et de la Technologie à l'école vise la construction d'un premier niveau de connaissances sur la matière et le vivant, par l'observation puis l'analyse raisonnée de phénomènes qui suscitent la curiosité des élèves. Cet enseignement doit permettre aux élèves de participer à la construction de leur propre savoir. Sa pédagogie les engage dans des activités d'investigation guidées par le maître. La confrontation des résultats obtenus à des ouvrages de référence (parmi lesquels les manuels scolaires occupent une place de choix) complète l'apport de ces activités. Elle consolide les connaissances acquises et contribue par ailleurs à l'apprentissage des stratégies de lecture adaptées à la spécificité de ces textes. Faire des sciences, c'est observer et expérimenter, mais c'est aussi lire, écrire, analyser des documents variés...

This book was released on 2013-03-09 with total page 654 pages. Available in PDF, EPUB and Kindle. Book excerpt: This volume contains edited contributions from the speakers at the NATO Advanced Research Workshop on "DNA Repair Mechanisms and Their Biological Implications in Mammalian Cells" held October 1-6, 1988, at the Abbaye Royale de Fontevraud, Fontevraud France. The meeting was dedicated to Paul Howard-Flanders (Yale University, New Haven, CT. , 1919-1988), whose seminal con tributions to the DNA repair field include the cO-discovery of the excision repair pathway, the elucidation of post-repli cation repair in E. coli, the isolation of the lexA and recC mutants, and his extensive work on the enzymology of RecA. A plethora of recent developments in DNA repair mechan isms and related processes in mammalian cells have advanced our understanding of this field in a number of different areas and have given new emphasis to the ways these systems both resemble DNA repair processes in other groups of organisms in some respects yet are strikingly different from them in others. Within the past decade there have been a number of international conferences on DNA damage and repair mechanisms but none has been focused on these processes in mammalian cells.

Available in PDF, EPUB and Kindle. Book excerpt: L'enseignement des Sciences expérimentales et de la technologie à l'école a deux objectifs : d'une part, il vise la construction d'un premier niveau de connaissances qui permet " de comprendre et décrire le monde réel, celui de la nature et celui construit par l'Homme, d'agir sur lui, et de maîtriser les changements induits par l'activité humaine " ; d'autre part, il implique la participation active des élèves à la construction de leur savoir par la mise en oeuvre d'une démarche d'investigation guidée par le professeur. Ce manuel de Sciences expérimentales et Technologie, conforme aux programmes publiés au Bulletin Officiel du 19 juin 2008, a été conçu pour fournir un outil de travail, adapté au niveau des élèves de CM2, qui apporte, sur les sujets du programme, des documents d'analyse, riches et variés, ainsi que des mises au point précises de l'essentiel des connaissances à maîtriser. Vous y trouverez : une sélection de documents pertinents dont l'analyse raisonnée permet aux élèves de participer à la construction de leur savoir ; un questionnement simple, toujours en relation avec les documents proposés sous la rubrique " Activités " ; une double page " J'ai découvert " et " J'utilise mes connaissances " qui résume ce qu'il faut retenir et permet de contrôler les différentes compétences acquises.
