Sommario/riassunto |
|
This reference covers the wide and rapidly growing field of biocatalysis. It combines complementary expertise from such areas as microbiology, enzymology, molecular biology structural biology and organic chemistry, thus highlighting the interdisciplinary nature of the subject.With its special focus on progress and new developments towards environmentally beneficial reactions with high levels of selectivity for the production of key compound classes, this book will enlighten both chemists and biologists as to the advances and opportunities existing in enzyme catalysis. |

Sommario/riassunto |
|
This volume aims at analyzing the relationship between the dialogical accomplishment of spoken talk-in-interaction on the one hand and entrenched patterns of linguistic and socio-cultural knowledge (constructions, frames, and communicative genres) on the other. The contributions analyze linguistic patterns in different languages such as English, French, German, and Swedish. Methodologically, they take up the usage-based position that structural and functional aspects of language use need to be studied empirically and "bottom-up": Since grammatical structure arises as the entrenched result of recurrent language use, its study should start with the local organization of natural talk-in-interaction before moving on to more complex and abstract relationships between linguistic structure, linguistic meaning, and socio-cultural activity/event patterns. Furthermore, they argue that Dialogism provides a promising starting point for a usage-based approach to linguistic patterns as both emerging (i.e. constructed in response to the situational circumstances of talk-in-interaction) and emergent (i.e. constructed with regard to symbolic units as parts of socially and culturally shared knowledge). |

Sommario/riassunto |
|
This work deals with the maximum achievable output flux of LED-projectors which is limited by physics. With the objective of increasing the output flux further, the illumination unit of LED-based projectors is enhanced systematically by improving existing technologies and developing new concepts. |
