The effects of herbs on the human body are set in a lucid and modern context. Simon Mills describes traditional herbal pathology and therapeutics, and also suggests up-to-date research methods to validate herbalism so that it can take its rightful place among the medical sciences. For practising herbalist and lay reader alike, the detailed pharmacology, based on the author's own extensive research and experience, will be of crucial interest: the active constituents of.

This concise introduction to modern climatology covers the key topics for intermediate undergraduate students on one-semester courses. The treatment of topics is non-mathematical wherever possible, instead focusing on physical processes to allow students to grasp concepts more easily. Full-color illustrations support the text and supplementary topics are covered in boxes, enabling students to further increase their knowledge and awareness. A historical perspective of climatology is woven throughout, providing students with an insight into key scientists and technological developments. Each chapter concludes with a summary of the main points and a mixture of review and discussion questions, encouraging students to check their understanding and think critically. A list of key web links to data and other resources, and solutions and hints to answers to the student questions (password-protected for instructors) are provided online to complete the teaching package.

Taking its place beside the instant classic bestseller The Whole Earth Catalog, this new, practical, comprehensive and profusely illustrated guide will prove invaluable to all consumers looking for a quick, efficient route to the very best information. Over 1,000 black-and-white illustrations.

A concise, non-mathematical, full-color introduction to modern climatology, covering the key topics of climate science for intermediate undergraduate students.

“All of the essential knowledge for completing a successful rammed earth project. Written by a geo-technical engineer with experience ramming earth.” —Kelly Hart, author, Essential Earthbag Construction Everything you need to know to build with rammed earth in warm and cold climates. Rammed earth—sand, gravel, and clay or lime/cement binder packed into forms—is a low-energy, high-performance building method, yielding beautiful, sustainable results. It’s thermally stable and can be insulated, can actively modulate humidity, provides a healthy indoor environment, and allows site materials to be used for major structural and building envelope elements. Essential Rammed Earth Construction covers design, building science, tools, and step-by-step building methods for any climate, with a special emphasis on building in cold climates of the northern US, Canada, and northern Europe. Coverage includes: Overview of earthen building Appropriate use of rammed earth walls Stabilized versus raw rammed earth Design considerations, including structural, insulation, and building envelope details Special considerations for cold and freeze-thaw climates Construction drawings, with step-by-step building instructions Tools and labor covering industrial methods, low-tech techniques, formwork options, mix design, budgets, and schedules Codes, inspections, and permits. This guide is an essential resource for experienced builders, DIY home owners, designers, engineers, and architects. “A much-needed and science-based update to a North American audience of designers, engineers and builders.” —Bruce King. P.E., author, The New Carbon Architecture “ A great book for anyone who wants to deepen their technical knowledge of rammed earth walls systems. It’s very helpful to have a book on rammed earth that is more focused on engineered rammed earth walls for cold climates.” —Clifton Schooley, Clifton Schooley & Associates, Rammed Earth Designers and Builders

Modern technology is pitted against ancient dinosaurs in this scientific thriller James Rollins calls “Jurassic Park set amid the paradox of time travel.” Paleontologist Richard Leyster is perfectly content in his position with the Smithsonian excavating dinosaur fossil sites and publishing his findings . . . until the mysterious Harry Griffin appears in his office with a cooler containing the head of a freshly killed Stegosaurus. The enigmatic stranger offers Leyster the opportunity to travel back in time to study living dinosaurs in their original habitats—but with strings attached. Soon, the paleontologist finds himself, along with a select team of colleagues—including his chief rival, the ambitious and often ruthless Dr. Gertrude Salley—making discoveries that would prove impossible working from fossils alone. But when Leyster and his team are stranded in the Cretaceous, they must learn to survive while still keeping alive the joy of scientific discovery. This shocking novel spans hundreds of millions of years and deals with the ultimate fate not only of the dinosaurs but also of all humankind. Nominated for the Locus Award, the Hugo Award, and the Nebula Award for Best Novel, Bones of the Earth cements author Michael Swanwick as an author who “proves that sci-fi has plenty of room for wonder and literary values” (San Francisco Chronicle).
