great and tragic mistake. They should have been promoting magnesium. Magnesium deficiency leads to an increase in myocardial levels of both sodium and calcium. This is a problem because Coronary Artery calcium is a predictor of near-term coronary heart disease events. In the face of growing magnesium deficiencies calcium becomes increasingly more toxic to human physiology. It is magnesium that actually controls bone density not calcium. Magnesium drives the calcium into the bones where low levels encourage

The sugarcane undergoing fermentation produced a volume of carbon dioxide that was nearly nine times more than the corn‚ wheat grain and wheat stalk. Wheat grain and corn was nearly doubled that of the wheat stalk and the control (Figure 1). Sugarcane was the leading plant material producing the highest volume of carbon dioxide (mean= 19.9 ± 0.996 mL) while other than the control; the wheat stalk produced the lowest volume of carbon dioxide (mean= 1.33 ± 0.036 mL). As time elapsed‚ the sugarcane

The invention of the internal combustion engine is most probably the result of the developments of several individuals. Around 1780‚ Dutch scientist Christiaan Huygens built an engine that used gunpowder as a fuel‚ but this engine was far too dangerous to be practical. His assistant‚ Denis Papin‚ also experimented with developing an internal combustion engine‚ building a simple steam-powered device around 1790. Again‚ this engine was not practical‚ and not until the early nineteenth century did the

Heat Pump ------------------------------------------------- A heat pump can provide an alternative to using your air conditioner. * Heat pumps can supply heat‚ cooling‚ and hot water. * Your climate and site will determine the type of heat pump most appropriate for your home. For climates with moderate heating and cooling needs‚ heat pumps offer an energy-efficient alternative to furnaces and air conditioners. Like your refrigerator‚ heat pumps use electricity to move heat from a
