There is a vast and often bewildering array of synthetic methods and reagents available to organic chemists today. The Best Synthetic Methods series allows any scientist who is interested in the chemical transformations of molecules to choose between all the alternatives and assess their real advantages and limitations. With the emphasis on laboratory use, these volumes represent a comprehensive and practical guide to modern synthetic organic chemistry. This book is the product of the authors many years practical experience and reading of the original literature. It contains a valuable distillation and critical evaluation of the Best Synthetic Methods for the formation and reaction of thiophenes (five membered heterocycles containing a ring sulfur) or polymers containing a thiophene functionality (thienyls). A brief review of each area is provided, but the emphasis in all cases is on describing efficient practical methods to effect the transformations described. The reader can therefore use this book to rapidly review and select the best methods of performing a synthetic conversion to create or modify a specifically substituted thiophene. Although this book contains many references to the original literature, the large number of experimental recipes enables the user to prepare a thiophene derivative without access to the original literature. These features make the handbook especially useful for physicists working in material sciences and organic/pharmaceutical chemists, who rapidly want to find out the availability of (or how to make) a specific thiophene. - Contains a systematic description and critical evaluation of the best methods for preparation of thiophenes and polymers containing thiophenes - Rapid location of methods achieved by systematic division of substituents following the periodic table - All chapters are richly illustrated by detailed experimental proceedures for the synthesis of five membered heterocycles containing sulfur
This intriguing novel follows German author Thomas Mann during three crucial days in 1936. Away in Switzerland and fearing arrest by the Nazis upon his return to Germany, Mann must choose whether to travel back to Munich. He decides to release an open letter to the regime in a Swiss newspaper but is then tortured by doubt: his Jewish publisher in Germany will be furious with the unwelcome attention Mann’s letter is sure to bring, and by choosing exile, isn’t the writer abandoning his loyal readers back home? Will the Nazis burn his books? Will they confiscate his diaries, which include intimate, homoerotic confessions? Britta Böhler shows us one of the twentieth century’s greatest writers as a family man, a father, a writer, and a man with moral doubts. We see a human soul trapped in a historical setting that forces him to make a seemingly impossible choice. A convincing depiction of a dilemma addressed only sparsely in Mann’s own writings, The Decision eloquently explores the all-too-human price of confronting totalitarianism.

This book addresses scientists and engineers involved in the areas of uranium mining and milling sites, clean-up measures, emissions of nuclear power plants and radioactive waste disposal, as well as political decision-makers. The topics covered are: impact on groundwater from radionuclide emission, analytical speciation techniques, chemical toxicity, radioisotope plant uptake, microbiology catalyzing U(6+) to U(4+) reduction, geochemical and reactive transport, case studies on abandoned uranium mines and milling sites, long-term storage of radioactive waste, passive in situ treatment techniques and risk assessment studies.
Afin de parvenir à une meilleure entente entre pays voisins, maîtriser une autre langue que sa langue maternelle serait souhaitable Selon ces recommandations, le Conseil de l'Europe et l'Union européenne présentent ici un projet sur l'enseignement et l'apprentissage des langues étrangères dans le contexte scolaire. Il a pour objectif de développer, dans le cadre du concept de plurilinguisme, les bases générales de méthodologie de langue tertiaire en les illustrant d'exemples, sur le modèle de la séquence linguistique "l'allemand après l'anglais ". Les organisateurs du projet, le Centre européen pour les langues vivantes du Conseil de l'Europe et le Goethe Institut Inter Nations, coopèrent à cet égard, en collaboration avec des institutions régionales actives dans le domaine de l'enseignement de langues étrangères.
