The New York Times bestselling true story of an all-American girl and a boy from Zimbabwe and the letter that changed both of their lives forever. It started as an assignment... Everyone in Caitlin's class wrote to an unknown student somewhere in a distant place. Martin was lucky to even receive a pen-pal letter. There were only ten letters, and fifty kids in his class. But he was the top student, so he got the first one. That letter was the beginning of a correspondence that spanned six years and changed two lives. In this compelling dual memoir, Caitlin and Martin recount how they became best friends—and better people—through their long-distance exchange. Their story will inspire you to look beyond your own life and wonder about the world at large and your place in it.
The mercurial Judy returns - and she’s in a mood to take on the world! Judy Moody did not set out to save the world. She set out to win a contest. A Band-Aid contest. It all started with the Crazy-Strip contest - and the dream that she, Judy Moody, might one day see her very own adhesive-bandage design covering the scraped knees of thousands. But when her "Heal the World" motif merits only an honorable mention, Judy Moody realizes it’s time to set her sights on something bigger. Class 3T is studying the environment, and Judy is amazed to learn about the destruction of the rain forest, the endangered species (not) in her own backyard, and her own family’s crummy recycling habits. Now she’s in a mood to whip the planet into shape - or her name isn’t Judy Monarch Moody!

The Report on Unidentified Flying Objects is a book by Edward J. Ruppelt which described the study of UFOs by United States Air Force from 1947 to 1955. Ruppelt was a United States Air Force officer best known for his involvement in Project Blue Book, a formal governmental study of unidentified flying objects. He is generally credited with coining the term "unidentified flying object." Because Ruppelt was the central axis of the government's investigation the book provides a unique insider look at how the government's efforts functioned.
This comprehensive book provides practical guidance on the care of the critical patient in the emergency department. It focuses on the ED physician or provider working in a community hospital where, absent the consulting specialists found in a large academic center, the provider must evaluate and stabilize critically ill and injured patients alone.

Emergency medicine scenarios covered across 38 chapters include acute respiratory failure, spinal cord Injuries, seizures and status epilepticus, care of the newborn, and end-of-life care.

If water is life, rainwater is a fountain of life. The purpose of this book is to show how various communities have caught that fountain of life using rainwater catchment systems. This book looks at real, practical, global experiences of rainwater catchment (a.k.a. rainwater harvesting) on individual, financially constrained, and community based levels through academic, mathematical and practical perspectives. This book can be used to learn practical skills, see inspiring examples, and to make math have more meaning. This book is for practitioners, DIYers, community members looking for water solutions, as well as for students and teachers in environmental science, environmental studies, sustainable design, international development, engineering, and mathematics. The book is broken into sections on rainwater catchment in general, types, components, gravity, calculations, implementation stories, useful links, conversions, and problem-sets.
