Our ears are sufficiently sensitive that they're capable of differentiating between variations in sound equivalent to less than one-billionth of atmospheric pressure, and our brains have the ability to identify and memorize complex aural patterns [sources: GSU, CNRS]. That ability probably evolved ...
Every mobile device from smartphones and e-readers to tablets and portable music players requires power to operate, which means sooner or later you'll have to charge them. That's when proprietary cables for multiple devices really become an irritation. It's enough to make you wonder, "How ...
T. Heroult, working independently, devised a method to extract aluminum from aluminum oxide. The process, a type of electrolytic reduction, required an enormous amount of electrical power, but it produced the metallic form in large quantities. By 1891, production of aluminum had reached well...
One notable program is "Cotton. From Blue to Green," launched in 2006 by Cotton Incorporated. The program targets college students, educating them about the renewable attributes of denim and encouraging them to donate their old jeans to the cause. Students can drop their jeans in campus collecti...
There are other losses as well. Electrons have to flow from one side of the cell to the other through an external circuit. We can cover the bottom with a metal, allowing for good conduction, but if we completely cover the top, then photons can't get through the opaque conductor and we...
The shorter the leaf spring, the closer to the bottom it will be, giving it the same semielliptical shape a single leaf spring gets from being thicker in the middle. Leaf springs also have different ends, depending on where they're connected to the frame. On double-eye leaf springs, the...

BDD, like many medical conditions, runs from mild to severe. Some people can accept that even though they may see their defects as obvious and unattractive, they know that they probably look "normal". However, others with BDD really believe that they appear to others as they do to themselve...

However, many cities are not ready to welcome the mass of rubber and aluminum from blocking pedestrian walkways and piling up in the public space [14]. Though the DBSS is a fairly new trend, the concerns about the popularity, the benefits and potential harm behind it has prompted a hot ...
