Here''s one golf book you should definitely own if you want to improve your game and lower your scores. Top golf instructor Martin Hall, host of Golf Channel''s weekly TV show, School of Golf, teaches you how to conquer challenging short-game shots as played by one of the all-time masters of the short game, Seve Ballesteros. By the time you''re done with this book you''ll have a fresh arsenal of short-game shots to choose from, whether it be running the ball through a bunker or hooking it around a tree, or hitting a super-high, super-soft flop shot that lands on the green like a butterfly with sore feet. You''ll uncover the secrets that made Ballesteros the most dominant and respected short-game player of his era—and put them to work to boost your own game.

Toxicity testing is used to assess the safety or hazards presented by substances such as industrial chemicals, consumer products, and pharmaceuticals. At present, many methods involve laboratory animals. Alternative procedures, some involving human cell-based technologies, are now being developed which reduce, refine, or replace animal usage and minimize the pain and distress caused. These new tests must protect public health and the environment at least as well as currently accepted methods. This book describes the ever-expanding "toolbox" of methods available to assess toxicity. Such techniques often result from our growing understanding of the biochemical and cellular pathways that mediate toxicity mechanisms. This permits evaluations of information generated from several sources to generate a "weight of evidence". By combining in silico, in vitro, and ex vivo methods with technologies that rely on biochemical- and cell-based in vitro assays, toxicologists are developing mechanistically based alternatives to live animal experimentation. This text also explores the complexities associated with adequate validation, and the assessment of test reliability and relevance. It provides an essential reference source for postgraduates, academics and industrialists working in this rapidly changing area.
