This book was released on 2011 with total page 205 pages. Available in PDF, EPUB and Kindle. Book excerpt: L’objectif principal de ce travail est de mettre en évidence l’intérêt du micromélange de réactifs dans la synthèse sol-gel de Fe(III)-TiO2 supporté et d’étudier le rôle joué par le dopant dans les processus de dégradation photocatalytique de l’éthylène. L’élaboration du photocatalyseur a été effectuée à partir des précurseurs tétraisopropoxyde de titane (TTIP) et de l’acétylacétonate de fer (Fe(acac)3). L’injection de ces derniers dans un mélange rendu turbulent permet le dopage au stade de nucléation des clusters oxo-TiO2 quasi monodisperses. Celui-ci a lieu par l’intermédiaire d’un complexe stable Fe(acac)3-oxo-TiO2. Le mécanisme de la réaction de dopage débute par la formation d’un monomère « particule-Fe(acac)2 » puis d’un dimère jusqu’à l’apparition d’un trimère où un ion Fe3+ est coordonné à 3 oxo-particules. La substitution des sites de surface des particules oxo-TiO2 par l’acétylacétone (Hacac) libérées diminue la vitesse d’induction de croissance des particules. Les résultats de cette étude ont montré la pertinence de notre approche sur la qualité du mélange même dans le cas des systèmes à cinétique de croissance lente. L’immobilisation des colloïdes hautement réactifs a été effectuée par nano-coating sur des substrats en verre. L’activité photocatalytique des nanodépôts a été conduite dans un réacteur tubulaire à lit fixe. La meilleure performance est obtenue pour un matériau dopé à 0,005 at.% et traité à 350°C. Ce résultat a été expliqué par la compétition du piégeage de trou par Fe3+ et de son annihilation sur Fe2+. Le modèle étudié permet d’estimer un volume de l’espace de localisation de l’électron après une photoexcitation et de définir une taille optimale des particules de l’ordre de ~8 nm. Un modèle de type Langmuir-Hinshelwood a été proposé pour décrire la cinétique de photooxydation de l’éthylène dans le domaine de concentration 35 - 300 ppm. L’ordre moyen de réaction déterminé proche de 1 permet de conclure que la vitesse de réaction dépend essentiellement de la concentration du polluant

Download or read book Mood Choice in Complement Clauses written by Toth and published by Peter Lang. This book was released on 2008 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: The volume investigates various approaches to mood distribution and mood variation in lexically selected complement clauses with special reference to Hungarian data. Its primary aim is to show that semantic factors play a crucial role in mood choice. The analysis focuses on the indicative/non-indicative opposition, the latter category includes the subjunctive, the imperative and the conditional. Critical discussion, revision and elaboration of previous semantic approaches pertaining to mood choice are presented, with particular emphasis on the applicability of the various analyses to mood phenomena in Hungarian. The author proposes two novel hypotheses about mood choice in Hungarian complement clauses.

Download or read book Teaching and Learning English Literature written by Ellie Chambers and published by SAGE. This book was released on 2006-03-14 with total page 241 pages. Available in PDF, EPUB and Kindle. Book excerpt: ′It is scarcely possible to imagine a truly educated person who cannot read well. Yet it is not clear how or even if courses in literature actually work. How can teachers of English help students in their developmental journey toward becoming skillful readers and educated persons? This is the complex question that Chambers and Gregory address in Teaching and Learning English Literature. The authors consider practical matters such as course design and student assessment but do not shirk larger historical and theoretical issues. In a lucid and non-polemical fashion - and occasionally with welcome humor - Chambers and Gregory describe the what, why, and how of "doing" literature, often demonstrating the techniques they advocate. Veteran teachers will find the book rejuvenating, a stimulus to examining purposes and methods; beginning teachers may well find it indispensable′ - Professor William Monroe, University of Houston ′The transatlantic cooperation of Ellie Chambers and Marshall Gregory has produced an outstanding book that ought to be on the shelves of anyone involved in the teaching of English Literature, as well as anyone engaged in the scholarship of teaching and learning in general or in any discipline. As they say, "the teaching of English Literature plays a central role in human beings′ search for meaning" although others in other disciplines may make this claim for theirs too. If so, they will still learn a great deal from this book; anyone looking for no more than a means of satisfying the demands of governments that look for simplistic quality measures and economic relevance, let them look elsewhere. This is a book for now and for all times′ - Professor Lewis Elton, Visiting Professor, University of Manchester, Honorary Professor, University College London This is the third in the series Teaching and Learning the Humanities in Higher Education. The book is for beginning and experienced teachers of literature in higher education. The authors present a comprehensive overview of teaching English literature, from setting teaching goals and syllabus-planning through to a range of student assessment strategies and methods of course or teacher evaluation and improvement. Particular attention is paid to different teaching methods, from the traditional classroom to newer collaborative work, distance education and uses of electronic technologies. All this is set in the context of present-day circumstances and agendas to help academics and those in training become more informed and better teachers of their subject. The book includes: - how literature as a discipline is currently understood and constituted - what it means to study and learn the subject - what ′good teaching′ is, with fewer resources for teaching, larger student numbers, an emphasis on ′user-pay′ principles and vocationalism. This is an essential text for teachers of English Literature in universities and colleges worldwide. The Teaching & Learning in the Humanities series, edited by Ellie Chambers and Jan Parker, is for beginning and experienced lecturers. It deals with all aspects of teaching individual arts and humanities subjects in higher education. Experienced teachers offer authoritative suggestions on how to become critically reflective about discipline-specific practices.

Download or read book EBOOK Environment and Identity in Later Life written by Sheila Peace and published by McGraw-Hill Education (UK). This book was released on 2005-12-16 with total page 192 pages. Available in PDF, EPUB and Kindle. Book excerpt: Throughout life, our everyday interactions with material, social, and psychological environments influence our self identity: and ‘who we think we are’ influences how we behave in particular places. In later life, people bring to this relationship a lifetime’s experience that makes certain associations more or less important. This book explores the relationship between environment and identity for older people. In this detailed ethnographic study, older people talk in depth about their situations and experiences of space and place. The book examines the experience of men and women of different ages and cultures living in a range of different kinds of places, including ‘ordinary’ and ‘special’ housing - from a high-rise flat to a residential care home - in semi-rural, urban and metropolitan locations within the Midlands and south-east England. This research enables us to appreciate how older people manage their needs within the context of their whole lives. Many are able to achieve a ‘life of quality’ as they constantly engage and re-engage with their environment. The discussion of how environmental complexity influences people in developing and maintaining their own identity is essential for those involved in planning, designing, caring and supporting people as they age. Environment and Identity in Later Life is key reading for students, practitioners and policy makers interested in quality of life for older people.

Download or read book Manifesto for Learning written by Janet Collins and published by A&C Black. This book was released on 2010-07-15 with total page 214 pages. Available in PDF, EPUB and Kindle. Book excerpt: What makes people learn effectively? What can we do to promote more effective learning?Innumerable researchers have studied these important and urgent questions, yet their findings tend to be fragmentary and disparate. Now Janet Collins, Joe Harkin and Melanie Nind provide the big picture. Drawing on research from all sectors of education the authors show that effective learning depends crucially on a few easily understood principles. These principles hold true regardless of the age or nature of the learner or the context in which the learner is working.Manifesto for Learning explains those principles and how to apply them, showing in the process how to make the vision of an effective learning society a reality.
Download or read book English for Primary and Early Years written by Ian Eyres and published by SAGE Publications Limited. This book was released on 2007-07-21 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: From a review of the first edition: 'Ian Eyres tackles every issue of the teacher training curriculum for English making it accessible and easy to understand. As well as this, he offers reflection pieces to check your own understanding... With English exams looming round the corner for my PGCE, this book really has been a lifesaver. Wholeheartedly recommended' - Amazon Review English for Primary and Early Years is a comprehensive and essential guide to the structure of English. It draws on the reader's own knowledge and understanding of English as the basis for analysis of texts at word, sentence and whole text level. The book develops the reader's understanding of the linguistic and literary knowledge required by the U.K.'s National Curriculum at Key Stages 1 and 2 and by the National Literacy Strategy. Key concepts such as, Standard English, approaches to grammar, genre, clause structure and the role of phonics in reading are addressed in an interactive way which develops the reader's skills as an active analyst of English, leading to a far deeper understanding than the `do's and don'ts' of traditional grammar. The text is fully updated to include the most recent developments in such areas as synthetic and analytic phonics and multimodal texts. An in-depth self-assessment activity is included with the text. This is a set book for the U.K. Open University Course, 'Ways of Knowing: language, mathematics and science in the early years'.
