Taschenbuch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - The structural complexity of lignin has continually challenged the in genuity of researchers to develop suitable methods for its charac terization prior to and following a wide variety of chemical, biologi cal, and physical treatments. Initially, activity along these lines was fueled by a desire to interpret technical delignification (Le. , pulping) processes in terms of accompanying structural changes in the lignin. Subsequently, increasingly wide ranging, in-depth investigations on the structure and reactivity of lignin exposed the inadequacy of many of the methods currently in use and underscored the ever-continuing need to develop new methods capable of solving the unique analytical problems associated with lignin. Characteristically, such methods should be selective, sensitive, suitable for quantitative measurements, and capable of being applied directly to, and without destruction of, the lignin or lignocellulose sample. One notable example of the head way being made in reaching this objective is the relatively recent devel opment and refinement of methods based on the use of sophisticated instrumentation, e. g. , lH_ and 13C-NMR spectroscopy. Although the utility of many of these and other recently developed methods de scribed in this book has yet to be fully and satisfactorily exploited, we believe that progress already made in this direction will continue and most likely accelerate. The decision to produce this book was prompted mainly by the acknowledged need for an up-to-date, single source compilation of lignin methodology. Hitherto, this need was, in part, satisfied by B. L.…

Buch. Zustand: Neu. Druck auf Anfrage Neuware - Printed after ordering - In this third, fully revised edition, the 10 volume Encyclopedia of Language and Education offers the newest developments, including an entirely new volume of research and scholarly content, essential to the field of language teaching and learning in the age of globalization. In the selection of topics and contributors, the Encyclopedia reflects the depth of disciplinary knowledge, breadth of interdisciplinary perspective, and diversity of socio-geographic experience in the language and education field. Throughout, there is an inclusion of contributions from non-English speaking and non-western parts of the world, providing truly global coverage. Furthermore, the authors have sought to integrate these voices fully into the whole, rather than as special cases or international perspectives in separate sections. The Encyclopedia is a necessary reference set for every university and college library in the world that serves a faculty or school of education, as well as being highly relevant to the fields of applied and socio-linguistics. The publication of this work charts the further deepening and broadening of the field of language and education since the publication of the first edition of the Encyclopedia in 1997 and the second edition in 2008.…
