This book is aimed at researchers who need to write clear and understandable manuscripts in English. Today, English is the official language of international conferences and most important publications in science and technology are written in English. Therefore, learning how to write in English has become part of the researcher's task. The book begins by discussing constructs of the English language such as sentence structure and word use. It then proceeds to discuss the style and convention used in scientific publications. This book is written at such a level that the reader should not have to resort to a dictionary. It includes many examples and exercises to clarify the rules and guidelines presented. Topics covered in this book include word choice - how to avoid redundancy; sentence and paragraph structure; the planning of a manuscript - format, nomenclature and style; how to present attractive figures and tables; references; how to prepare a manuscript for publication; submission to a journal and checking of proofs; and some standard abbreviations and symbols.
