Linda Sue Park Website A Long Walk to Water: based on a true story Clarion Books, November 15, 2010 A Long Walk to Water is based on the true story of Salva, one of some 3,800 Sudanese "Lost Boys" airlifted to the United States beginning in the mid 1990s. Before leaving Africa, Salva's life is one of harrowing tragedy. How to Build a Natural Swimming Pool Learn how to build a natural swimming pool in order to create a cooling summer retreat for your homestead. Whether you like to practice your dolphin dives or lounge away the day on a raft, swimming is one of summer's perfect pleasures. With a minimum of materials and without an arsenal of chemicals, you can build an idyllic water oasis right in your own back yard and thwart summertime's sultry dog days. Though fairly common in Europe, natural swimming pools (like the one pictured above in an Austrian family's backyard), are in their infancy in the United States. Ask most American swimming-pool contractors to build a backyard pool and chances are they'll roll out a long list of goods, including rebar, gunite, fiberglass, chlorine and an energy-sapping filtration system. But in recent years, a few builders and a growing number of homeowners have learned how to build pools without relying on a mass of manufactured materials and chemical additives.

Processing - Please Wait. "An Exceptionally Simple Theory of Everything"[1] is a physics preprint proposing a basis for a unified field theory, very often referred to as "E8 Theory,"[2] which attempts to describe all known fundamental interactions in physics and to stand as a possible theory of everything. The paper was posted to the physics arXiv by Antony Garrett Lisi on November 6, 2007, and was not submitted to a peer-reviewed scientific journal.[3] The title is a pun on the algebra used, the Lie algebra of the largest "simple", "exceptional" Lie group, E8. The theory received accolades from a few physicists[citation needed] amid a flurry of media coverage, but also met with widespread skepticism.[4] Scientific American reported in March 2008 that the theory was being "largely but not entirely ignored" by the mainstream physics community, with a few physicists picking up the work to develop it further.[5] Overview[edit]

Bug-out bag Off-the-shelf Red Cross preparedness kit . A bug-out bag[1][2] is a portable kit that contains the items one would require to survive for seventy-two hours[3][4] when evacuating from a disaster. The focus is on evacuation, rather than long-term survival, distinguishing the bug-out bag from a survival kit, a boating or aviation emergency kit, or a fixed-site disaster supplies kit. The kits are also popular in the survivalism subculture.[5] The term "bug-out bag" is related to, and possibly derived from, the "bail-out bag" emergency kit many military aviators carry. In the United States, the term refers to the Korean War practice of the U.S.

Desalination Desalination, desalinization, and desalinisation refer to any of several processes that remove some amount of salt and other minerals from saline water. More generally, desalination may also refer to the removal of salts and minerals,[1] as in soil desalination, which also happens to be a major issue for agricultural production.[2] Salt water is desalinated to produce fresh water suitable for human consumption or irrigation. One potential byproduct of desalination is salt. Desalination is used on many seagoing ships and submarines.

Connecticut Coalition to Save Darfur Next Meeting Thursday, May 24, 2012 10:30 A.M. Harry and Jeanette Weinberg Community Services Building Zachs Campus 333 Bloomfield Road (entrance is on Simsbury Road) West Hartford, CT 06117 (860) 727-6100 Directions "Experts" Push For Lithium To Be Added To Our Drinking Water Apparently there are not enough chemicals already added to our drinking water, as there is now a call by “experts” to further poison our water supplies by adding Lithium. Their main reason is to decrease suicide and violent crime rates. So it this how we wish to function as a society? Elementary Particle Explorer Welcome to the Elementary Particle Explorer, designed by Garrett Lisi and Troy Gardner. Every known elementary particle is identified by its charges with respect to the electromagnetic, weak, strong, and gravitational forces. Electrons have electric charge -1, up quarks 2/3, down quarks -1/3, and neutrinos 0, with antiparticles having opposite electric charges. In the Standard Model, as you are about to see, these electric charges are a combination of the particles' hypercharge, Y, and weak charge, W. The Elementary Particle Explorer (EPE) allows you to rotate in charge space (by dragging the image), showing the charges of all known particles.

How to Grow 100 Pounds of Potatoes in 4 Square Feet On many occasions, we've been tempted to grow our own potatoes. They're fairly low maintenance, can be grown in a pot or in the ground, last a fairly long time if stored properly, and can be very nutritious (high in potassium and vitamin C). Here's more incentive: according to this article, you can grow 100 pounds of potatoes in 4 sq. feet. Learn how after the jump... According to this article from the Seattle Times, potatoes planted inside a box with this method can grow up to 100 pounds of potatoes in just 4 square feet. All that is required:

OECD calls for policy reform and technology to prevent impending water crisis The OECD has released a report outlining the challenges humanity faces to maintain water resources in the future (Photo: Shutterstock) Image Gallery (2 images) Worldwide population growth and the related rapid increase in urbanization is already posing problems in many areas for the management of that most precious of resources, water. With these problems only set to intensify, the Organization for Economic Co-Operation and Development (OECD) has released a report outlining the challenges humanity faces to maintain water resources in the face of demographic growth and climate change. Educator Resources: Sudan Civil War-Lost Boys-Darfur Explore the experience of three Sudanese "Lost Boys" as they return to Sudan 20 years after fleeing their homes to escape Civil War. Part 1: Background Rebuilding Hope is a documentary film directed by Pulitzer Center journalist, Jen Marlowe. The film explores the experience of three Sudanese "Lost Boys" as they return to Sudan in 2007, 20 years after fleeing their homes to escape the Sudanese Civil War.

How to Detox Your Pineal Gland – Fluoride, Mercury, & Consciousness Waking Times Is there a natural herb or treatment to detox from fluoride, mercury, and pineal gland calcification? The first intentional addition of fluoride in drinking water occurred in the early 1930′s in Nazi Germany. Marketing it as supposed helping children’s teeth, the actual sodium fluoride was to sterilize humans and force the masses into a calm docile state of submission and declining health-state.
