Hydraulic mining. Hydraulic mining, or hydraulicking, is a form of mining that uses high-pressure jets of water to dislodge rock material or move sediment. In the placer mining of gold or tin, the resulting water-sediment slurry is directed through sluice boxes to remove the gold. It is also used in mining kaolin and coal.
Each 1-cup serving of fresh grapes contains 22 micrograms of vitamin K. For a man, this amount supplies 18 percent of his recommended daily allowance; for a woman, a cup of grapes fulfills 24 percent of her vitamin K requirement per day.
The scientists aren't sure yet. But so far, they say grapes may have protective potential against cancer that is independent of its antioxidant properties. Plus, reams of other research encourage eating plenty of produce -- at least five fruits and veggies a day for maximum benefits, say health experts.
