Standards are replacing tariffs as the main trade barriers facing African agro-food exports. This book examines the challenges and opportunities that new public and private standards present to African countries - focusing on food safety, environmental and climate change, and social and labour standards.

The authors show how and why standards are used as governance tools. They follow the historical development of standards and their new forms and roles, across the substantive areas of industrial and organizational "quality," the financial sector, environment, and labor.

The need for dialysis access surgery is growing rapidly as the population of patients with end stage renal failure expands. This book is aimed at those healthcare professionals involved in the care of patients undergoing dialysis. "Vascular Access Simplified" gives a comprehensive review of all aspects of adult dialysis access with a specific emphasis on haemodialysis. The text highlights some of the difference in practises of physicians in Europe and the USA. The contributors are allied professionals, physicians, radiologists, vascular and transplant surgeons who have a specific interest and are all committed to improving the quality of dialysis access. The approach of each chapter is essentially practical with a few chosen references to aid further study rather than an exhaustive bibliography.

Expand your understanding of the physics and practical clinical applications of advanced radiation therapy technologies with Khan's The Physics of Radiation Therapy, 5th edition, the book that set the standard in the field. This classic full-color text helps the entire radiation therapy team--radiation oncologists, medical physicists, dosimetrists, and radiation therapists--develop a thorough understanding of 3D conformal radiotherapy (3D-CRT), stereotactic radiosurgery (SRS), high dose-rate remote afterloaders (HDR), intensity modulated radiation therapy (IMRT), image-guided radiation therapy (IGRT), Volumetric Modulated Arc Therapy (VMAT), and proton beam therapy, as well as the physical concepts underlying treatment planning, treatment delivery, and dosimetry.
In preparing this new Fifth Edition, Dr. Kahn and new co-author Dr. John Gibbons made chapter-by-chapter revisions in the light of the latest developments in the field, adding new discussions, a new chapter, and new color illustrations throughout. Now even more precise and relevant, this edition is ideal as a reference book for practitioners, a textbook for students, and a constant companion for those preparing for their board exams.
