The genus Microtoena is a lovely and enigmatic member of the mint family. This new monograph is a comprehensive taxonomic revision, based on extensive field observations, population sampling, specimen examinations, scanning electron microscopy observations, statistical analysis of characters, and molecular phylogenetic analysis. Detailed species descriptions are enhanced by 20 maps, 18 full page line drawings and numerous field photos. This is an essential reference for taxonomists, growers, breeders and horticulturalists. Qiang WANG. Associate Professor at the State Key Laboratory of systematic and Evolutionary Botany, Institute of Botany, Chinese Academy of Sciences. A young taxonomist, his main interests are taxonomy, phylogeny and evolution of Lamiaceae, and his passion for Microtoena stretches back 10 years.

This invaluable look provides a comprehensive treatment of design and applications of semiconductor optical amplifiers (SOA). SOA is an important component for optical communication systems. It has applications as in-line amplifiers and as functional devices in evolving optical networks. The functional applications of SOAs were first studied in the early 1990's, since then the diversity and scope of such applications have been steadily growing. This is the second edition of a book on Semiconductor Optical Amplifiers first published in 2006 by the same authors. Several chapters and sections rep

Advances in Textile Biotechnology, Second Edition examines the latest in biotechnology for the fiber and textile industry. This new edition has been fully revised to include the current essential areas of development in the field, covering both natural and synthetic fibers. Chapters cover the latest technology in bioprocessing for bast fiber, PVA, polyester, wool and silk before exploring issues of enzyme stability. Essential areas of application and development are then considered, including biomedical textiles, silk materials for biotechnological applications, bacterial cellulose, the ink jetting of enzymes, and the role of enzymes, wool and silk fibers.Containing groundbreaking research, this book will be essential reading for manufacturers, designers and engineers in the textiles industry, textile and fiber scientists, and academic researchers and postgraduate students working in the area of textile technology.

This edited volume documents the state of the art in research into how the age factor interacts with other factors in a variety of educational contexts. The book comprises 17 chapters examining early language learning and teaching in a range of countries in Europe, Asia and North America. Authors discuss main themes in research methodology, curricular and assessment issues, short- and long-term outcomes, the role of individual differences, innovation in teacher education, classroom processes, as well as the impact of the target language. The first two chapters (Nikolov; Edelenbos and Kubanek) overview the main trends in research. Four papers (Curtain;Ofra Inbar-Lourie and Elana Shohamy; Jalkannen; Haenni Hoti, Heinzmann, and Müller) focus on the assessment of young learners; two authors examine how age impacts on language learning over time (Muñoz; Kasai). Individual differences (motivation, anxiety, aptitude, and socio-economic status) are explored byMihaljevi? Djigunovi?, Mattheoudakis and Alexiou, and Kiss. Innovation is the common theme in chapters written by Wang, Moon, and Peng and Zhang. The last three papers analyze the status of languages (Harris, Enever, Carmel). The book is a must have for teacher educators of pre- and in-service teachers of modern languages to young learners, MA and PhD students in TEFL/TESOL and other languages, researchers and policy makers.
