Sommario/riassunto |
|
This much-needed book presents a clear and very practice-oriented overview of thermal separation processes. An extensive introduction elucidates the physical and physicochemical fundamentals of different unit operations used to separate homogenous mixtures. This is followed by a concise text with numerous explanatory figures and tables referring to process and design, flowsheets, basic engineering and examples of separation process applications.Very helpful guidance in the form of process descriptions, calculation models and operation data is presented in an easy-to- understand manner |

Sommario/riassunto |
|
The study of native language influence in Second Language Acquisition has undergone significant changes over the past few decades. This book, which includes 12 chapters by distinguished researchers in the field of second language acquisition, traces the conceptual history of language transfer from its early role within a Contrastive Analysis framework to its current position within Universal Grammar. The introduction presents a continuum of thought starting from the late 70s, a time in which major rethinking in the field regarding the concept of language transfer was beginning to take place, a |
