Book excerpt: Medical Education: Theory and Practice is a new text linking the theory and the practice for graduate students and educators who want to go beyond the basics. The scholarship of medical education is, above all, a ‘practice’, but one that has a strong theoretical foundation. Neither theory nor practice stand still, and both are grounded in research. The novelty of this book lies in its interweaving of practice, theory, innovation and research. The book starts with a theorised, contemporary overview of the field. Next, it explores the theoretical foundations of medical education in depth. The remainder of the book reviews a whole a range of educational contexts, processes and outcomes. This work has been edited by a distinguished, international team of medical educationalists and written by equally accomplished authors from across the globe representing a spectrum of disciplines. This will be an invaluable text for all Masters Students in health professions education as well as PhD students and education researchers wanting a background to the discipline. Educators and medical students will also find it a very useful resource. Written by key figures in medical educational research combined with a strong editorial influence from the international editorial team. The text has a strong evidence-based approach that is fully cognisant of research methodology issues, The book provides a scholarly explanation on the topic, rather than aiming to say the last word. Written throughout in a clear and comprehensible style. The content is extensively referenced with additional suggestions for further reading.

The text provides hints drawn from practical experience to help teachers create powerful learning opportunities for their students, providing readable guidelines and introducing new techniques that potentially could be adopted for use in any teaching programme. Throughout the book introduces some key basic principles that underpin the practical advice that is given and which will help to inform teaching practice. This book will assist readers to reflect on and analyse with colleagues the different ways that their work as a teacher or trainer can be approached and how their student or trainee's learning can be made more effective.

Available in PDF, EPUB and Kindle. Book excerpt: L'objectif de la thèse est la simulation numérique de l'hydrodynamique et du mélange en colonnes à bulles. En régime homogène, les bulles de gaz montent uniformément; en augmentant le débit de gaz, le régime devient hétérogène avec la présence de "grosses" structures. Ces structures ont un caractère instationnaire et contribuent au mélange. Il s'agit donc de simuler ces structures. La première partie explique l'apparition des "grosses" structures à partir d'une analyse de stabilité d'une colonne à bulles. Un régime d'écoulement permanent et établi est perturbé. L'analyse détermine dans quelles conditions la perturbation s'amplifie. Notre approche permet d'unifier des travaux antérieurs et d'expliquer les différences entre les modèles. Le rôle prépondérant de la déformation des bulles est intégré à l'analyse de stabilité. L'analyse est validée à partir de mesures de la vitesse du gaz et la vitesse de propagation des ondes, à différentes vitesses de liquide. L'analyse de stabilité permet aussi de déterminer la transition entre régimes d'écoulement en colonne à bulles et en conduite. La deuxième partie est consacrée à la simulation numérique. Des simulations ont été menées dans un système parallélépipédique, fermé au liquide, avec une injection de gaz ponctuelle. La prédiction de "grosses" structures en présence d'un panache gazeux est validée avec les travaux de Sokolichin & Eigenberger (1994). Nous retrouvons le rôle déterminant de la modélisation de la masse ajoutée. Nous avons simulé une colonne à bulle de section rectangulaire, fermée au liquide avec une injection de gaz uniforme, en testant différentes options de modélisation de la traînée et de la masse ajoutée. A ces simulations de l'hydrodynamique ont été couplés des traçages effectués sur une hydrodynamique instationnaire qui démontrent le rôle essentiel des "grosses" structures sur le mélange dans une colonne à bulles.
