Book Description
Disordered nature of structural arrangement in amorphous and nanocrystalline alloys gives rise to advantageous soft magnetic properties in particular from a practical application viewpoint [1]. Especially nanocrystalline alloys attract a lot of scienti?c interest because, contrary to their amorphous counterparts, their magnetic parameters do not substantially deteriorate at elevated temperatures during the process of their practical exploitation. To bene?t from their unique magnetic pr- erties, the mechanism of crystallization should be known. Here, we present the study of structural transformation of NANOPERM-type alloys by the help of Mössbauer spectrometry, conventional X-ray diffraction (XRD), and by an advanced diffraction of synchrotron radiation. 2 Experimental Alloys of the composition Fe Mo Cu B for x = 12, 15, 17, 20 prepared by 91?x 8 1 x 57 rapid quenching on a rotating wheel were analyzed in the as-cast state by Fe transmission Mössbauer spectrometry (TMS) and by conversion electron Mössbauer spectrometry (CEMS). The obtained as-quenched ribbons were about 10 mm wide and 20 ?m thick. The nanocrystalline state was achieved by annealing about 2 cm ? long samples for 1 h at temperatures up to 650 C in a vacuum. Conventional XRD was performed with Cu-K radiation in Bragg-Brentano con?guration with graphite ? monochromator in the diffracted beam. Monochromatic synchrotron radiation of 7keV(? = 0. 178 nm) provided at the KMC-2 beamline at BESSY Berlin was used for in situ examinations of structural transformations during continuous heat treatment.

Book Description
World Englishes is a vibrant research field that has attracted scholars from many different linguistic subdisciplines. Emphasizing the common ground of all research on World Englishes, the 22 articles in this collected volume, selected from more than a hundred papers presented at the 2007 conference of the International Association for World Englishes in Regensburg, cover a broad range of topics which together reflect the state of the art of research in this field. The volume focuses on regions as diverse as Africa, the Caribbean, the Antipodes and Asia, but also promotes a globally comparative perspective by analyzing selected characteristics of the English language across a wide range of varieties. Methodologically, a number of different approaches are applied, including corpus linguistic studies, socio-phonetics as well as historical discourse analysis. Due to its wide scope, the book is of interest not only to World Englishes scholars but also to sociolinguists as well as applied, contact or corpus linguists.

Book Description
The eleven contributions to this volume, written by expert corpus linguists, tackle corpora from a wide range of perspectives and aim to shed light on the numerous linguistic and pedagogical uses to which corpora can be put. They present cutting-edge research in the authors’ respective domain of expertise and suggest directions for future research. The main focus of the book is on learner corpora, but it also includes reflections on the role of other types of corpora, such as native corpora, expert users corpora, parallel corpora or corpora of New Englishes. For readers who are already familiar with corpora, this volume offers an informed account of the key role that corpus data play in applied linguistics today. As for readers who are new to corpus linguistics, the overview of approaches, methods and domains of applications presented will undoubtedly help them develop their own taste for corpora. This volume has been edited in honour of Sylviane Granger, who has been one of the pioneers of learner corpus research.

Book Description
This volume provides an overview of four currently booming areas in the discipline of corpus linguistics. The first section is concerned with studies of the history and development of morphological and syntactic phenomena in English, Spanish, and Mandarin Chinese. The second section contains case studies investigating the functions and contexts of use of different morphological and syntactic forms in English, Spanish, Russian, and Mandarin Chinese. The third section contains studies in the field of genre and register from settings as diverse as health, call center, academic, and legal discourse. The final section features papers refining existing, and exploring new, corpus-linguistic methods: dispersions, text mining, corpus similarity, as well as the development of extraction patterns and the evaluation of tagging methods.

Book Description
The Late Modern period is the first in the history of English for which an unprecedented wealth of textual material exists. Using increasingly sophisticated databases, the contributions in this volume explore grammatical usage from the period, specifically morphological and syntactic change, in a broad context. Some chapters explore the socio-historical background of the period while others provide information on prescriptivism, newspaper language, language contact, and regional variation in British and American English. Internal processes of change are discussed against grammaticalisation theory and construction grammar and the rich body of textual evidence is used to draw inferences on the precise nature of historical change. Exposing readers to a wealth of data that informs the description of a broad range of syntactic phenomena, this book is ideal for graduate students and researchers interested in historical linguistics, corpus linguistics and language development.

Book Description
Growing up, we go through many struggles. the manner of which we deal with those struggles differs from person to person. Paul took a different method for overcoming those challenges he faced. for all the negativity, frustration, anger, depression, and the lack of self-worth he had in his life, he looked toward his journal. He wrote in his journal as if having a conversation with himself. Paul dedicated all his writing to coaching himself toward finding a positive perspective and greater understanding of his life experiences. He now seeks to help others through the insights he gained.
