Updated in line with the 18th Edition of the Wiring Regulations and written specifically for the EAL Diploma in Electrical Installation, this book has a chapter dedicated to each unit of the EAL syllabus, allowing you to master each topic before moving on to the next. This new edition also includes information on LED lighting. End of chapter revision questions help you to check your understanding and consolidate the key concepts learned in each chapter.

This is the number one textbook for all EAL level 2 courses in electrical installation. It sets out the core facts and principles with solid explanation - not just to pass the exam but to confidently work as an electrician with a proper understanding of the regulations. Ideal for both independent and tutor-based study.

In Teaching Critical Thinking, renowned cultural critic and progressive educator bell hooks addresses some of the most compelling issues facing teachers in and out of the classroom today.

In a series of short, accessible, and enlightening essays, hooks explores the confounding and sometimes controversial topics that teachers and students have urged her to address since the publication of the previous best-selling volumes in her Teaching series, Teaching to Transgress and Teaching Community. The issues are varied and broad, from whether meaningful teaching can take place in a large classroom setting to confronting issues of self-esteem. One professor, for example, asked how black female professors can maintain positive authority in a classroom without being seen through the lens of negative racist, sexist stereotypes. One teacher asked how to handle tears in the classroom, while another wanted to know how to use humor as a tool for learning.

Addressing questions of race, gender, and class in this work, hooks discusses the complex balance that allows us to teach, value, and learn from works written by racist and sexist authors. Highlighting the importance of reading, she insists on the primacy of free speech, a democratic education of literacy. Throughout these essays, she celebrates the transformative power of critical thinking. This is provocative, powerful, and joyful intellectual work. It is a must read for anyone who is at all interested in education today.

The 2nd edition of Fundamentals of Wastewater Treatment and Design introduces readers to the fundamental concepts of wastewater treatment, followed by engineering design of unit processes for sustainable treatment of municipal wastewater and resource recovery. It has been completely updated with new chapters to reflect current advances in design, resource recovery practices and research. Another highlight is the addition of the last chapter, which provides a culminating design experience of both urban and rural wastewater treatment systems.

Filling the need for a textbook focused on wastewater, it covers history, current practices, emerging concerns, future directions and pertinent regulations that have shaped the objectives of this important area of engineering. Basic principles of reaction kinetics, reactor design and environmental microbiology are introduced along with natural purification processes. It also details the design of unit processes for primary, secondary and advanced treatment, as well as solids processing and removal. Recovery of water, energy and nutrients are explained with the help of process concepts and design applications.

This textbook is designed for undergraduate and graduate students who have some knowledge of environmental chemistry and fluid mechanics. Professionals in the wastewater industry will also find this a handy reference.
