Flaxseed, similar to soy, is rich in phytoestrogens and high in omega-3 fatty acids. Phytoestrogens found in flaxseed can help increase estrogen levels and combat vaginal dryness, and they're known to help relieve a variety of other menopausal symptoms as well. Flax can also help lower LDL (bad cholesterol).
Compressed Natural Gas. CNG is produced by compressing natural gas to less than 1% of its volume at standard atmospheric pressure. To provide adequate driving range, CNG is stored onboard a vehicle in a compressed gaseous state within fuel tanks at a pressure of 3,000 to 3,600 pounds per square inch.
Electroencephalography (EEG) is an electrophysiological monitoring method to record electrical activity of the brain. It is typically noninvasive, with the electrodes placed along the scalp, although invasive electrodes are sometimes used in specific applications. EEG measures voltage fluctuations resulting from ionic current within the neurons of the brain.
