Communicative proficiency and linguistic development
The Common European Framework of Reference for Languages (CEFR) has become the yardstick for teaching and testing language skills in Europe and elsewhere. Yet little is known about the relationships between the communicative levels established using the can-do statements of the CEFR and the developmental stages of grammatical and lexical development described by Second Language Acquisition (SLA) research. This book presents empirical research by members of the SLATE network (Second Language Acquisition and Testing in Europe), aimed at bridging this gap. The studies deal with several target languages, including Dutch, English, Finnish, French, Italian, Norwegian and Spanish, with adult, adolescent and child learners in both formal and informal contexts.

Mathematical Modeling of Disperse Two-Phase Flows
This book develops the theoretical foundations of disperse two-phase flows, which are characterized by the existence of bubbles, droplets or solid particles finely dispersed in a carrier fluid, which can be a liquid or a gas. Chapters clarify many difficult subjects, including modeling of the interfacial area concentration. Basic knowledge of the subjects treated in this book is essential to practitioners of Computational Fluid Dynamics for two-phase flows in a variety of industrial and environmental settings. The author provides a complete derivation of the basic equations, followed by more advanced subjects like turbulence equations for the two phases (continuous and disperse) and multi-size particulate flow modeling. As well as theoretical material, readers will discover chapters concerned with closure relations and numerical issues. Many physical models are presented, covering key subjects including heat and mass transfers between phases, interfacial forces and fluid particles coalescence and breakup, amongst others. This book is highly suitable for students in the subject area, but may also be a useful reference text for more advanced scientists and engineers.
