Transforming the Materials Economy Written by Alex Nicoll (http://www.newgreeneconomy.com) The Materials Economy The Materials Economy has been the driving force behind U.S. economics since the Second World War. The name refers to the raw materials from which its products are made. The marketing and sale of these products is what keeps the Materials Economy in motion‚ while exhausting natural resources and generating incalculable amounts of waste. Consumer products manufactured and sold in

Salt Saturation & How it Affects Salt Crystal Size 12/07/11 Research Question: How does the saturation of water affect the size of the salt crystals? This project was chosen because it was intriguing and to find out if more salt equals bigger crystals. Hypothesis: If the water is more saturated then the salt crystals will be bigger. The Independent Variable is the amount of salt in the water. The Dependent Variable is the size of the salt

Jupiter is composed primarily of gaseous and liquid matter. It is the largest of four gas giants as well as the largest planet in the Solar System with a diameter of 142‚984 km at its equator. The density of Jupiter‚ 1.326 g/cm3‚ is the second highest of the gas giant planets. The density is lower than any of the four terrestrial planets. Jupiter’s upper atmosphere is composed of about 88–92% hydrogen and 8–12% helium by percent volume or fraction of gas molecules. Since a helium atom has about

Comparison of side effects‚ limitations and risks. For the both ionising and non-ionising radiation there are many side effects‚ risks and limitations. In ionising radiation‚ there is a risk of cell mutation which can result in developing cancer if there is overexposure of the radiation to the patient’s. In the worst state this radiation can result in death. This type of radiation is not recommended to the groups of people like children‚ pregnant women or the elderly as it will expose them to higher

is the basis of major economic activities in a number of specialized technologies. A brief overview of methods is presented here; for detailed coverage‚ see the cross-referenced articles. Rust is permeable to air and water‚ therefore the interior metallic iron beneath a rust layer continues to corrode. Rust prevention thus requires coatings that preclude rust formation. Rust-resistant alloys: Stainless steel and Weathering steel. Stainless

Definition of UFO An unidentified flying object‚ or UFO‚ in its most general definition‚ is any apparent anomaly in the sky that is not identifiable as a known object or phenomenon. Such anomalies may later be identified‚ but depending on the evidence or lack of evidence‚ such an identification may not be possible generally leaving the anomaly unexplained. While stories of unexplained apparitions have been told since antiquity‚ the term "UFO" (or "UFOB") was officially created in 1953 by theUnited
