This book confronts the issue of how young people can find a way into the world of algebra. It represents multiple perspectives which include an analysis of situations in which algebra is an efficient problem-solving tool, the use of computer-based technologies, and a consideration of the historical evolution of algebra. The book emphasizes the situated nature of algebraic activity as opposed to being concerned with identifying students' conceptions in isolation from problem-solving activity.

When finding another location, redesigning a structure, or removing troublesome ground at a project site are not practical options, prevailing ground conditions must be addressed. Improving the ground-modifying its existing physical properties to enable effective, economic, and safe construction-to achieve appropriate engineering performance is an increasingly successful approach. This third edition of Ground Improvement provides a comprehensive overview of the major ground improvement techniques in use worldwide today. Written by recognized experts who bring a wealth of knowledge and experience to bear on their contributions, the chapters are fully updated with recent developments including advancements in equipment and methods since the last edition. The text provides an overview of the processes and the key geotechnical and design considerations as well as equipment needed for successful execution. The methods described are well illustrated with relevant case histories and include the following approaches: Densification using deep vibro techniques or dynamic compaction Consolidation employing deep fabricated drains and associated methods Injection techniques, such as permeation and jet grouting, soil fracture grouting, and compaction grouting New in-situ soil mixing processes, including trench-mixing TRD and panel-mixing CSM approaches The introductory chapter touches on the historical development, health and safety, greenhouse gas emissions, and two less common techniques: blasting and the only reversible process, ground freezing. This practical and established guide provides readers with a solid basis for understanding and further study of the most widely used processes for ground improvement. It is particularly relevant for civil and geotechnical engineers as well as contractors involved in piling and ground engineering of any kind. It would also be useful for

This volume is part of the Complete Works of Evelyn Waugh critical edition, which brings together all Waugh's published and previously unpublished writings for the first time with comprehensive introductions and annotation. The edition's General Editor is Alexander Waugh, Evelyn Waugh's grandson and editor of the twelve-volume Personal Writings sequence, which collates all Waugh's letters, diaries, and other personal writings in chronological order. Volume one of the series covers the years 1903-1921, ending with Waugh's departure from Lancing College, aged 18, with a scholarship to Hertford College, Oxford. For many years at Lancing Waugh kept a daily account of his life, and every diary entry is reprinted here along with the lively pen-and ink drawings that accompanied them and the letters he sent to his parents and friends. No other book presents such a rich anthology of writing by a school-boy, let alone one who would later turn into a major literary figure and novelist of genius.
