The Molecule on the Front Cover is Paclitaxel, C47H51NO14 a chemotherapy drug that has been successful in treating breast, lung, and ovatian cancer. It is extracted from the bark of the Pacific Yew tree (Taxus brevifolia). Unfortunately, the bark of a 100-year-old Pacific Yew tree yields about 3 kg of bark and only 300 mg of paclitaxel, barely enough for a single dose of the drug (Taxol). The synthesis of this molecule engaged the attention of chemists for more than 20 years until finally, in 1994, chemists from Florida State University and from the University of California (San Diego) announced independently that they were able to synthesize it from simpler and readily available starting materials. A major challenge in the synthesis of paclitaxel is getting the spatial arrangement of atoms around 11 of the carbon atoms just right. These 11 carbon atoms are identified in the ball-and-stick structure by green or purple circles. If the synthesis is not done carefully, up to 2048 different possible paclitaxel-like structures could be obtained, but only one is known to have the desired anti-tumor activity. Because chemists can now synthesize paclitaxel, it is possible for researchers to explore how it works and design new chemotherapeutic drugs that are safer and more effective.

Computer Modeling Applications for Environmental Engineers in its second edition incorporates changes and introduces new concepts using Visual Basic.NET, a programming language chosen for its ease of comprehensive usage. This book offers a complete understanding of the basic principles of environmental engineering and integrates new sections that address Noise Pollution and Abatement and municipal solid-waste problem solving, financing of waste facilities, and the engineering of treatment methods that address sanitary landfill, biochemical processes, and combustion and energy recovery. Its practical approach serves to aid in the teaching of environmental engineering unit operations and processes design and demonstrates effective problem-solving practices that facilitate self-teaching. A vital reference for students and professional sanitary and environmental engineers this work also serves as a stand-alone problem-solving text with well-defined, real-work examples and explanations.

Basic Chemistry, Third Edition gives you the problem-solving tools and techniques you'll need to succeed in future chemistry courses and in the work force. In a clear, friendly writing style, Timberlake continues to make chemistry relevant and engaging. Her unique “Guide to Problem-Solving” strategy provides a visual, step-by-step plan that helps to solve a wide variety of problems. Sample and practice problems throughout each chapter help you practice and master quantitative skills. Real-world applications cover modern, interesting topics in helping connect chemical principles to events in today's world, while interviews with engineers, doctors, veterinarians, and biochemists show the importance of chemistry in future careers. This edition features the exact same content as the traditional text in a convenient, three-hole- punched, loose-leaf version. Books à la Carte also offer a great value—this format costs 35% less than a new textbook.
