Available in PDF, EPUB and Kindle. Book excerpt: FROM THE PREFACE Wastewater collection systems are dynamic, not static. There is no single maintenance method, equipment, or technique that works best. Keeping an open mind, trying new techniques and technologies benefits sewer system operators. No two collection systems are alike. Maintenance staffing, skill levels, equipment, budgets, age and complexity of the system make each agency unique. However, collection systems do have many traits and problems in common. Based on inventory and analysis, problems are identified. Defects may then be prioritized, and corrective maintenance operations put into effect. Preventive maintenance techniques can be applied to all collection systems. Preventive maintenance is cost-effective; it strives to prevent problems from occurring rather than reacting to difficult situations and "putting out fires." This book examines problems shared by all agencies: roots, grease, deterioration, hydraulic inefficiencies and structural defects. New solutions to age-old problems are applied: TV inspection and video interpretation, rehabilitation analysis and trenchless technologies. Computerized maintenance management and GIS softwares are discussed. Jetting, line cleaning and exciting developments in nozzle technology are included. Roots and chemical root control foam, wastewater control and grease are major topics as well. Wastewater Collection System Maintenance shares insights drawn from operator experience, trial and error, successes and failures in the field, interviews and years of research and studies. A user-friendly rating and evaluation system is explained and applied to field conditions. Equipment operation and maintenance, and "tricks of the trade" are also discussed. As cities grow, new systems are extended upstream from older sewers. Many of these core drainage basins are now under capacity and in need of capital improvement projects. There are approximately 600,000 miles of sanitary sewers in the country. Nationwide, there exists a huge backlog of sewer pipes that need rehabilitation. Replacement would cost many billions of dollars. Maintenance operators are entrusted with the care and feeding of an aging sewer infrastructure.

Available in PDF, EPUB and Kindle. Book excerpt: The Craft and Science of Coffee follows the coffee plant from its origins in East Africa to its current role as a global product that influences millions of lives though sustainable development, economics, and consumer desire.For most, coffee is a beloved beverage. However, for some it is also an object of scientifically study, and for others it is approached as a craft, both building on skills and experience. By combining the research and insights of the scientific community and expertise of the crafts people, this unique book brings readers into a sustained and inclusive conversation, one where academic and industrial thought leaders, coffee farmers, and baristas are quoted, each informing and enriching each other.This unusual approach guides the reader on a journey from coffee farmer to roaster, market analyst to barista, in a style that is both rigorous and experience based, universally relevant and personally engaging. From on-farming processes to consumer benefits, the reader is given a deeper appreciation and understanding of coffee's complexity and is invited to form their own educated opinions on the ever changing situation, including potential routes to further shape the coffee future in a responsible manner. - Presents a novel synthesis of coffee research and real-world experience that aids understanding, appreciation, and potential action - Includes contributions from a multitude of experts who address complex subjects with a conversational approach - Provides expert discourse on the coffee calue chain, from agricultural and production practices, sustainability, post-harvest processing, and quality aspects to the economic analysis of the consumer value proposition - Engages with the key challenges of future coffee production and potential solutions

This book, with contributions from many of the world’s top experts in chemistry education, is a major publication offering something that has not previously been available. Within this single volume, chemistry teachers, teacher educators, and prospective teachers will find information and advice relating to key issues in teaching (such as the curriculum, assessment and so forth), but contextualised in terms of the specifics of teaching and learning of chemistry, and drawing upon the extensive research in the field. Moreover, the book is written in a scholarly style with extensive citations to the literature, thus providing an excellent starting point for teachers and research students undertaking scholarly studies in chemistry education; whilst, at the same time, offering insight and practical advice to support the planning of effective chemistry teaching. This book should be considered essential reading for those preparing for chemistry teaching, and will be an important addition to the libraries of all concerned with chemical education. Dr Keith S. Taber (University of Cambridge; Editor: Chemistry Education Research and Practice) The highly regarded collection of authors in this book fills a critical void by providing an essential resource for teachers of chemistry to enhance pedagogical content knowledge for teaching modern chemistry. Through clever orchestration of examples and theory, and with carefully framed guiding questions, the book equips teachers to act on the relevance of essential chemistry knowledge to navigate such challenges as context, motivation to learn, thinking, activity, language, assessment, and maintaining professional expertise. If you are a secondary or post-secondary teacher of chemistry, this book will quickly become a favorite well-thumbed resource! Professor Hannah Sevian (University of Massachusetts Boston)
