Magnesium cannot be made in our body like all minerals, which is why we need to take it in through magnesium-rich foods.
The Brinell hardness number (HB) is the load divided by the surface area of the indentation. The diameter of the impression is measured with a microscope with a superimposed scale. The Brinell Hardness Number is computed from the equation: P is the applied load of 3000, 1500, or 500kg.
Problems with water softener. I bought my house in November 2009 and it has a midway 5600 water softener that was installed July 2000. I was an idiot and didn't maintain the softener at all.
